  However, in the conventional seat connector, the connection state between the male connector and the female connector is unstable, and there is a case where conduction is momentarily interrupted, that is, instantaneous interruption occurs. This is because, when the male connector and the female connector are multipolarized, and the size and thickness are reduced, the bump housing holes 922 are formed into the thin female side base 911 with a precise shape and a narrow pitch. Since it becomes difficult to form, the position, shape and dimensions of the female electrode pattern 951 formed around the bump housing hole 922 become inaccurate, and as a result, contact with the bump 851 becomes uncertain. This is because even a slight external force, vibration or the like affects the contact state between the bump 851 and the female electrode pattern 951.

  The present invention solves the problems of the conventional sheet connector, and the female terminal formed of a plate-shaped metal includes a pair of contact portions that elastically clamp the male terminal from both sides, The contact with the female terminal can be stably maintained, the occurrence of instantaneous interruption can be surely prevented, and the manufacture is easy, the configuration is simple, the cost is low, the size is small, and the reliability is high. An object is to provide a high sheet connector.

A sheet connector that fits (mates) with a mating connector, wherein the connection recess includes a flat terminal that engages with a mating terminal of the mating connector, and the flat terminal patterns the conductor pattern. And a pair of contact portions that include an inner opening formed on the inner side thereof, are connected to a portion around the flat plate terminal in the conductor pattern, and a pair of contact portions that face each other. includes an arm portion connecting the base and the contact portion, said base portion is connected to one part and the other part of the periphery of the plate-like terminals in the conductor pattern An upper base and a lower base, and the arm includes an upper arm and a lower arm that connect the contact portion to the upper base and the lower base, and the inner opening has a pair of opposing faces. The portion between the upper arm portions is larger than the portion between the pair of opposed lower arm portions , and the interval between the pair of opposed contact portions is the width dimension of the inner opening and When the flat terminal is smaller than the width dimension of the counterpart terminal and the flat terminal engages with the counterpart terminal, the pair of contact portions elastically clamp the counterpart terminal from both sides.

  In another seat connector of the present invention, the inner opening further includes a shape in which a width dimension gradually decreases when approaching a portion between the pair of contact portions.

  In still another sheet connector of the present invention, the conductor pattern further includes a frame existing on both left and right sides of the flat terminal, and a pair of left and right outer sides located between the frame and the contact portion or the arm portion. The upper base and the lower base are connected to the left and right frames.

  In still another sheet connector of the present invention, the flat terminal further includes a bridge portion that connects the upper arm portion and the lower arm portion outside the contact portion.

  In still another seat connector of the present invention, at least one of the upper base portions has a crank shape.

  According to the present invention, in the sheet connector, the female terminal formed of a plate-like metal includes a pair of contact portions that elastically sandwich the male terminal from both sides. Thereby, contact with a male terminal and a female terminal can be maintained stably, and generation | occurrence | production of a momentary interruption can be prevented reliably. In addition, the thickness of the female terminal can be reduced, and the height of the seat connector can be reduced. Further, the manufacturing can be easily performed, the configuration is simple, the cost is low, and the size is small, but the reliability can be improved.

  In the figure, reference numeral 1 denotes a male connector as a first connector which is one of the seat connectors in the present embodiment, and is electrically connected to a female connector 101 as a second connector described later. The male connector 1 has a flat cable portion 12 and a flat connection portion 11 integrally formed at the tip of the cable portion 12. Note that intermediate recesses 13 as recesses for engaging with the female connector 101 are formed on the left and right sides of the boundary portion between the cable portion 12 and the connection portion 11.

  In the present embodiment, expressions showing directions such as upper, lower, left, right, front, rear, etc., used to explain the configuration and operation of each part included in the male connector 1, the female connector 101, and other members. Is not absolute but relative, and is appropriate when the male connector 1, female connector 101 and other parts included in the other members are in the posture shown in the figure. When the posture of each part included in the connector 101 and other members is changed, it should be interpreted according to the change in the posture.

  The male connector 1 has, for example, a dimension in the width direction of the connection portion 11 (direction connecting the upper left and lower right in FIG. 1) of about 10 to 15 mm, and the front-rear direction of the connection portion 11 (lower left in FIG. 1). The dimension of the connecting portion 11 in the thickness direction is approximately 0.3 to 0.5 mm, and the intermediate recess 13 is approximately 2 in the longitudinal direction. Although the member has a dimension of about 4 mm, the dimension can be changed as appropriate.

  The cable portion 12 is a flat flexible cable called a flexible circuit board (FPC: Flexible Printed Circuit), a flexible flat cable (FFC: Flexible Flat Cable), or the like. As long as it is a cable or a substrate, it may be of any kind. The cable portion 12 includes a base film 15 as a male substrate portion that is a plate-like first substrate portion that is an insulating thin plate member having an elongated strip shape, and one surface of the base film 15 (FIG. 7). A conductor pattern 51 as a male conductor, which is a first conductor functioning as a plurality of conductive wires arranged in parallel on the upper surface of FIG. Further, on the other surface of the conductor pattern 51 (upper surface in FIG. 7), a cover film 17 as a male covering portion which is a plate-like first covering plate portion which is an insulating thin plate member having an elongated strip shape is formed. It is arranged. That is, the cable portion 12 is a flat member having a layer structure in which the base film 15, the conductor pattern 51, and the cover film 17 are laminated in this order from the bottom.

  The base film 15 and the cover film 17 are made of, for example, a resin such as polyimide, but may be made of any kind of material as long as it has insulating properties. The conductor pattern 51 is formed by, for example, etching a copper foil (foil) having a thickness of several [μm] to several tens [μm], which is pasted on one surface of the base film 15 in advance. And formed by patterning.

  The example shown in the figure shows a case where the male connector 1 is used for connection to a power supply, and the conductor pattern 51 includes a pair of wide patterns 51a and a pair of narrow patterns arranged in parallel to each other. The adjacent conductor patterns 51 are separated from each other by a pattern separation space 52. For example, the wide pattern 51a is used as a ground line, and the narrow pattern 51b is used as a power line. In addition, the number of the said conductor patterns 51, a pitch, and the aspect of arrangement | sequence can be changed suitably as needed. For example, when the male connector 1 is used for signal line connection, each conductor pattern 51 is formed like a narrower linear body and has a predetermined pitch, for example, 0.1 [ mm], and a large number of them are arranged in parallel with each other.

  The cable portion 12 is usually a long belt-like member, but in the drawing, for the sake of illustration, the rear portion (upper right in FIG. 1) is cut away. Note that another flat cable can be connected behind the cable portion 12.

  The connecting portion 11 also has a base film 15 and a conductor pattern 51 disposed on one surface of the base film 15. The conductor pattern 51 is formed continuously from the cable portion 12 and terminates in the connection portion 11. In the example shown in the figure, the conductor pattern 51 extends to the distal end portion 11a of the connection portion 11 and terminates at the distal end portion 11a. However, the conductor pattern 51 may terminate in the middle of the connection portion 11. A reinforcing layer 16 as a plate-shaped reinforcing plate portion, which is a flat thin plate member, is disposed on the other surface of the base film 15 (the lower surface in FIG. 7). The reinforcing layer 16 is made of, for example, a metal such as stainless steel. The material thereof may be a resin, a composite material including glass fiber, carbon fiber, or the like, or any kind of material. It may be. That is, the connection part 11 is a flat plate-like member having a layer structure in which the reinforcing layer 16, the base film 15, and the conductor pattern 51 are laminated in this order from the bottom.

  And the ear | edge part 21 extended in the width direction outer side rather than the intermediate | middle recessed part 13 is respectively provided in the right-and-left both sides of the said connection part 11. As shown in FIG. The ear portion 21 is a portion that functions as a convex portion for engaging with the female connector 101, and a rear end portion thereof is a male fitting lock portion 22 as a fitting lock portion. Then, the male fitting lock portion 22 engages with a female fitting lock portion 122 of the female connector 101 described later, and locks so that the fitting state between the male connector 1 and the female connector 101 is maintained.

  In the example shown in the figure, the width dimension of the connection part 11 is equal to the width dimension of the cable part 12, but it is not necessarily equal to the width dimension of the cable part 12. It may be larger or smaller.

  The ear portion 21 is a strip-like thick portion extending in the front-rear direction of the male connector 1 and includes an insertion convex portion 56 protruding upward from the surface of the connection portion 11. The side edge of the insertion convex portion 56 is formed so as to coincide with the side edge 21 a of the ear portion 21, and is recessed inward in the width direction at a portion near the rear end thereof, that is, a portion near the male fitting lock portion 22. A locking recess 56a formed to enter is provided. The locking recess 56a is locked to a locking projection 156a of the female connector 101 described later, and prevents the engagement between the male fitting lock portion 22 and the female fitting lock portion 122 from being released.

  In the example shown in the figure, the insertion convex portion 56 is formed integrally with the conductor pattern 51 on the surface of the conductor pattern 51, but is not necessarily a member integral with the conductor pattern 51. A member separate from the conductor pattern 51 may be used.

  As shown in FIGS. 2 to 4, the male fitting lock portion 22 includes a male side step portion 23 as a fitting step portion formed on the back surface. The male side step portion 23 is a step portion formed so as to be recessed from the back surface of the connection portion 11, more specifically, from the back surface of the reinforcing layer 16, and is substantially orthogonal to the back surface of the connection portion 11, The step part end surface 23a extended in the direction parallel to the width direction of the connection part 11 and the level | step difference surface 23b extended in parallel with the back surface of the connection part 11 are included. The boundary on the inner side in the width direction of the connection portion 11 in the male side step portion 23 is defined by the side edge 13 a of the intermediate recess 13.

  In the connecting portion 11, the surface of the conductor pattern 51 is exposed, and a plurality of protruding terminals 53 as male terminals are disposed on the surface of the conductor pattern 51. In the example shown in the figure, the projecting terminals 53 are arranged in a lattice shape and are arranged so as to form a pair of rows extending in the width direction. Specifically, in the wide pattern 51a, three protruding terminals 53 are included in each row, and in the narrow pattern 51b, one protruding terminal 53 is included in each row, and protruding terminals in the front row and the rear row are included. 53 is located on a straight line extending in the front-rear direction of the male connector 1. That is, the male connector 1 is arranged so as to form a rectangular (2) planar lattice having lattice lines as axes extending in the front-rear direction and the left-right direction. In addition, the arrangement | sequence aspect of the protrusion terminal 53 is not limited to the example shown by a figure, It can change arbitrarily.

  Each of the protruding terminals 53 is a member protruding upward from the surface of the conductor pattern 51, and is formed integrally with the conductor pattern 51 by, for example, a method such as etching using a photolithography technique. The height of the protruding terminal 53, that is, the position of the upper surface is the same as the position of the upper surface of the insertion convex portion 56 in the example shown in FIG. It is not necessary to be the same as the position of the upper surface, and may be higher or lower than the position of the upper surface of the insertion convex portion 56.

  Further, the shape of the upper surface and the transverse section of the protruding terminal 53 is larger in the front-rear direction than in the width direction, as clearly shown in FIG. The upper part in a) is preferably a pentagon or hexagon like a baseball base with a pointed base, but it is not necessarily limited to the example shown in the figure. ) It may be circular and can be changed arbitrarily.

  In the present embodiment, the side shape of the protruding terminal 53 is concave as shown in FIG. Specifically, in the protruding terminal 53, the width dimension of the base end portion 53a that is a portion connected to the surface of the conductor pattern 51 is equal to or larger than the width size of the tip end portion 53b that is the upper end portion, and the base end portion 53a and The side surface portion 53c between the distal end portion 53b is a smooth and smooth surface that is recessed toward the inner side in the width direction from the proximal end portion 53a and the distal end portion 53b, and in the middle thereof, The minimum point 53d where the width dimension is minimum is included. In other words, the width dimension of the protruding terminal 53 is the maximum at the base end portion 53a, gradually decreases as it goes upward, becomes minimum at the minimum point 53d, increases gradually as it goes further upward, and increases at the tip end portion 53b. The size is the same as or smaller than that of the base end portion 53a. The shape of the side surface portion 53c is desirably a gently continuous curved surface, but may be a curved surface in which a plurality of slopes are continuous.

  Moreover, the side shape of the protruding terminal 53 when viewed from the side of the male connector 1 is also a concave surface as shown in FIG. That is, the width dimension of the base end part 53a is equal to or larger than the width dimension of the tip end part 53b, and the side surface part 53c is a surface that is recessed toward the inside in the width direction from the base end part 53a and the tip end part 53b. In the middle, a minimum point 53d having a minimum width dimension is included. In other words, the width dimension of the protruding terminal 53 is the maximum at the base end portion 53a, gradually decreases as it goes upward, becomes minimum at the minimum point 53d, increases gradually as it goes further upward, and increases at the tip end portion 53b. The size is the same as or smaller than that of the base end portion 53a.

  When the protruding terminal 53 is engaged with a receiving terminal 153 (described later) of the female connector 101, the side surface portion 53c is elastically sandwiched from both sides by a pair of contact portions 153c (described later) of the receiving terminal 153. . As will be described later, the receiving terminal 153 is a thin member, and the thickness dimension (vertical dimension) of the contact portion 153c is smaller than the height dimension (vertical dimension) of the protruding terminal 53. When receiving an external force or receiving a vibration, the contact portion 153c may move in the vertical direction of the protruding terminal 53 along the side surface portion 53c. However, since the side surface portion 53c is a smooth concave surface and includes the minimum point 53d, the position of the contact portion 153c elastically pressed by the side surface portion 53c always converges to the minimum point 53d, and the Since the elastic pressing force increases as the distance from the minimum point 53d increases, the contact portion 153c does not separate from the side surface portion 53c. That is, since the side surface portion 53c is concave, contact between the side surface portion 53c and the contact portion 153c is reliably maintained even when subjected to external force or vibration. No interruption occurs.

  Next, the configuration of the female connector 101 will be described.

  FIG. 8 is a perspective view of the female connector according to the first embodiment of the present invention as viewed from the front side, FIG. 9 is a three-view diagram of the female connector according to the first embodiment of the present invention, and FIG. FIG. 11 is a perspective view of a reinforcing layer of a female connector in the first embodiment of the present invention, and FIG. 12 is a first embodiment of the present invention. It is a top view which shows the modification of the female terminal of the female connector in. 9A is a top view, FIG. 9B is a front view, FIG. 9C is a bottom view, and FIGS. 12A to 12D are first to fourth modified examples. is there.

  In the present embodiment, the female connector 101 is a second connector as the other of the seat connectors, has a rectangular planar shape, and is electrically connected to the male connector 1 as the first connector which is the mating connector. It is connected and mounted on the surface of a substrate such as a printed circuit board or a flexible circuit board (not shown). In this case, the female connector 101 has a flat plate shape, is mounted so that the back surface thereof faces the front surface of the substrate, and is electrically connected to the conductive traces of the substrate.

  The female connector 101 has a flat frame body 111 having a substantially U-shaped surface. The frame body 111 extends in the width direction of the female connector 101 (the direction connecting the lower right and the upper left in FIG. 8), and forward from both ends of the horizontal frame 111a (lower left in FIG. 8). ) Is provided with a vertical frame portion 111b extending toward the top. A wide portion 113 that engages with the intermediate recess 13 of the male connector 1 is formed at the front end of the vertical frame portion 111b.

  And the flat flat recessed part provided with the rectangular planar shape demarcated by the said frame 111 is the connection recessed part 114 which accommodates the connection part 11 of the male connector 1. FIG. The bottom 114a of the connection recess 114 is a flat member having a layer structure in which a base film 115, a conductor pattern 151, and a cover film 117 are laminated in this order from the bottom. The frame body 111 is a thick plate-like member as compared with the connection recess 114.

  The female connector 101 has, for example, a width of the frame body 111 of about 11 to 16 [mm], and a front and rear direction of the frame body 111 (a direction connecting the lower left and the upper right in FIG. 8) of about 5 to 5. Although it is a plate-shaped member having a dimension of 7 [mm] and a thickness of the frame body 111 of about 0.3 to 0.5 [mm], the dimension can be changed as appropriate.

  The conductor pattern 151 is a female conductor as a second conductor that functions as a plurality of conductive wires, and is etched into a copper foil having a spring property with a thickness of several [μm] to several tens [μm], for example. It is formed by applying patterning and the like.

  The example shown in the figure shows a case where the female connector 101 is used for connection to a power source, and the conductor pattern 151 includes a pair of wide patterns 151a and a pair of narrow patterns arranged in parallel to each other. The adjacent conductor patterns 151 are separated from each other by a pattern separation space 152. For example, the wide pattern 151a is used as a ground line, and the narrow pattern 151b is used as a power line. Note that the number, pitch, and arrangement of the conductor patterns 151 can be changed as appropriate. For example, when the female connector 101 is used for signal line connection, each conductor pattern 151 is formed like a narrower linear body and has a predetermined pitch, for example, 0.1 [ mm], and a large number of them are arranged in parallel with each other.

  In the figure, 158a and 158b are a wide rear tail portion and a narrow rear tail portion formed integrally with the wide pattern 151a and the narrow pattern 151b so as to protrude rearward from the horizontal frame portion 111a of the frame body 111. And connected to a connection pad formed on the surface of the substrate (not shown) by soldering or the like. Reference numeral 158c denotes a front tail portion formed integrally with the wide pattern 151a so as to protrude forward from the wide portion 113 of the frame body 111, and is soldered to a connection pad formed on the surface of the substrate (not shown). Connected by appending etc. When the wide rear tail portion 158a, the narrow rear tail portion 158b and the front tail portion 158c are described in an integrated manner, the tail portion 158 will be described. By connecting the tail portion 158 to the connection pad, the female connector 101 is fixed to the substrate, and the conductor pattern 151 is electrically connected to the corresponding conductive trace of the substrate.

  A receiving terminal 153 as a female terminal, which is a plurality of flat-plate terminals, is disposed at a portion corresponding to the bottom 114 a of the connection recess 114 in the conductor pattern 151. Since the receiving terminal 153 is a member that is engaged and electrically connected to the protruding terminal 53 of the male connector 1 that is the counterpart terminal, the arrangement thereof is the same as the arrangement of the protruding terminal 53. And when the arrangement | sequence aspect of the protrusion terminal 53 is changed, the arrangement | sequence aspect of the receiving terminal 153 is also changed so that it may adapt. Furthermore, since the conductor pattern 151 is also a member that conducts with the conductor pattern 51 of the male connector 1, the arrangement thereof is the same as the arrangement of the conductor pattern 51 of the male connector 1. When is changed, the arrangement pattern of the conductor pattern 151 is also changed so as to be adapted thereto.

  Each of the receiving terminals 153 is a member accommodated in a substantially rectangular terminal accommodating opening 154 that penetrates the conductor pattern 151 in the thickness direction. For example, the conductor pattern 153 is formed by a method such as etching using a photolithography technique. It is formed by patterning 151. Typically, the remaining pattern formed by patterning the conductor pattern 151 is the receiving terminal 153, and the portion where the material around the receiving terminal 153 is removed is the terminal receiving opening 154. Therefore, the thickness dimension of the receiving terminal 153 is equivalent to the thickness dimension of the conductor pattern 151.

  The planar shape of each receiving terminal 153 is bilaterally symmetric. Each receiving terminal 153 includes a base portion 153a connected to a peripheral portion of the receiving terminal 153 in the conductor pattern 151, that is, a peripheral edge of the terminal receiving opening 154, a pair of arm portions 153d connected to the base portion 153a, and each arm. A pair of contact portions 153c connected to the distal ends of the portions 153d and a pair of free end portions 153b connected to the distal ends of the contact portions 153c are provided. The left and right arm portions 153d, the contact portion 153c, and the free end portion 153b are symmetrical members that face each other. The arm portion 153d is a cantilever-like member that functions as a spring, and the free end portion 153b and the contact portion 153c are elastically displaced in the width direction of the female connector 101 due to the spring property of the arm portion 153d.

  The terminal receiving opening 154 includes an inner opening 154 a inside the receiving terminal 153 and an outer opening 154 b outside the receiving terminal 153. The inner opening 154a is a portion into which the protruding terminal 53 enters and is accommodated when the receiving terminal 153 is engaged with the protruding terminal 53 of the male connector 1, and the outer opening 154b is the arm portion 153d, This is a portion that allows displacement of the free end portion 153b and the contact portion 153c.

  In the inner opening 154a, the portion between the opposing arm portions 153d has a large area, and typically the width dimension is larger than the width dimension of the distal end portion 53b of the protruding terminal 53, and The vertical dimension is also larger than the vertical dimension of the tip 53 b of the protruding terminal 53. Therefore, the protruding terminal 53 can smoothly enter the inner opening 154a. On the other hand, the portion between the contact portions 153 c facing each other is a narrow space, and typically the width dimension is smaller than the width dimension at the minimum point 53 d of the protruding terminal 53. Therefore, when the projecting terminal 53 accommodated in the inner opening 154a moves relatively between the contact portions 153c, the interval between the contact portions 153c abuts on the side surface portion 53c of the projecting terminal 53 and is expanded. The contact portion 153c is pressed against the side surface portion 53c of the protruding terminal 53 by the spring property of the arm portion 153d. That is, the pair of contact portions 153c elastically sandwich the side surface portion 53c of the protruding terminal 53 from both sides.

  The shape of the inner opening 154a is such that the width dimension gradually decreases when approaching the portion between the contact portions 153c. That is, the vicinity of the contact portion 153c at the side edge of the opposing arm portion 153d has an inclined tapered shape. Therefore, the protruding terminal 53 can smoothly enter the portion between the contact portions 153c facing each other.

  In the vicinity of both ends of the conductor pattern 151 in the width direction, insertion concave portions 156 that are substantially rectangular openings for accommodating the insertion convex portions 56 of the male connector 1 are formed. Each of the insertion recesses 156 is an opening that penetrates the conductor pattern 151 in the thickness direction, similarly to the terminal receiving opening 154. For example, the conductor pattern 151 is patterned by a method such as etching using photolithography technology. It is formed by doing. A locking projection 156a is formed on the outer edge of the insertion recess 156 near the front end. The locking projection 156a is a projection formed at the tip of a cantilever member that functions as a spring, and is elastically displaced in the width direction of the female connector 101 by the spring property of the cantilever member. The locking projection 156 a locks a locking recess 56 a formed on the side edge of the insertion projection 56 of the male connector 1, and the engagement between the male fitting lock portion 22 and the female fitting lock portion 122. Prevents the combination from being released.

  The base film 115 is a female substrate portion as a second substrate portion that is an insulating thin plate member, and is made of, for example, a resin such as polyimide, but may be any kind of material as long as it has an insulating property. May be. The base film 115 has a terminal-corresponding opening 115a and a recess-corresponding opening 115b penetrating the base film 115 in the thickness direction at portions corresponding to the receiving terminals 153 and the insertion recesses 156 formed in the conductor pattern 151. Each is formed. The receiving terminals 153 form a pair of rows extending in the width direction, and are arranged so that the receiving terminals 153 in the front row and the rear row are positioned on a straight line extending in the front-rear direction of the female connector 101. Whereas, each of the terminal corresponding openings 115a has a rectangular shape that is long in the front-rear direction so as to correspond to the pair of receiving terminals 153 in the front row and the rear row.

  The cover film 117 is a female covering portion as a second covering plate portion that is an insulating thin plate member, and is made of, for example, a resin such as polyimide. It may be a material. The cover film 117 has a terminal-corresponding opening 117a and a recess-corresponding opening 117b penetrating the cover film 117 in the thickness direction at portions corresponding to the receiving terminals 153 and the insertion recesses 156 formed in the conductor pattern 151. Each is formed. Each of the terminal corresponding openings 117a has a rectangular shape elongated in the front-rear direction so as to correspond to the pair of receiving terminals 153 in the front row and the rear row.

  And the bottom part 114a of the connection recessed part 114 formed by laminating | stacking the said base film 115, the conductor pattern 151, and the cover film 117 is equipped with the ear | edge accommodation recessed part 121 arrange | positioned at the width direction both ends. The ear receiving recess 121 corresponds to the recess-corresponding opening 115b of the base film 115, the insertion recess 156 of the conductor pattern 151, and the recess-corresponding opening 117b of the cover film 117, and is an opening that penetrates the bottom 114a in the thickness direction. ing. The terminal accommodating opening 154 corresponds to the terminal corresponding opening 115a of the base film 115 and the terminal corresponding opening 117a of the cover film 117, and is an opening that penetrates the bottom 114a in the thickness direction. In the example shown in the figure, the conductor pattern 151 and the cover film 117 do not exist in the corresponding part between the left and right wide portions 113, and only the base film 115 exists.

  Further, a frame reinforcing layer 116 is laminated on the cover film 117. The frame reinforcing layer 116 is a thin plate member having a substantially U-shaped surface shape, and is made of, for example, a metal such as stainless steel or a resin such as polyimide. It may be a material or an insulating material. Further, as shown in FIG. 10, the frame reinforcing layer 116 may be a member formed by laminating a first frame reinforcing layer 116a and a second frame reinforcing layer 116b, as shown in FIG. As a result, a single member configured integrally may be used. As shown in FIG. 10, when the first frame reinforcing layer 116a and the second frame reinforcing layer 116b are laminated, for example, the material of the first frame reinforcing layer 116a is a metal such as stainless steel. In addition, different materials can be used in combination such that the second frame reinforcing layer 116b is made of resin such as polyimide.

  The frame reinforcing layer 116 is a member constituting the uppermost layer of the frame body 111, and the surface shape thereof matches the surface shape of the frame body 111. And as FIG. 11 shows, the frame reinforcement layer 116 has the wide part 116c corresponding to the wide part 113 of the frame 111, The rear end (upper right end in FIG. 11) part of this wide part 116c is It functions as a female fitting lock part 122 as a fitting lock part. Since the wide portion 113 is located at the front end of the ear receiving recess 121 (the lower left end in FIG. 8), the female fitting lock portion 122 becomes the front end portion of the ear receiving recess 121 and is the male fitting lock of the male connector 1. It engages with the part 22 and locks so that the fitting state of the male connector 1 and the female connector 101 is maintained.

  The female fitting lock portion 122 includes a female side step portion 123 as a fitting step portion formed on the back surface. The female-side step portion 123 is a step portion that is formed so as to be recessed from the back surface of the frame reinforcing layer 116, and is substantially orthogonal to the back surface of the frame reinforcing layer 116 and the surface of the female connector 101. It includes a stepped end surface 123a extending in a direction parallel to the width direction, and a stepped surface 123b extending in parallel to the back surface of the frame reinforcing layer 116 and the surface of the female connector 101. The step end surface 123a corresponds to the front edge of the recess-corresponding opening 115b of the base film 115, the insertion recess 156 of the conductor pattern 151, and the recess-corresponding opening 117b of the cover film 117.

  In the present embodiment, the planar shape of the receiving terminal 153, which is a flat terminal, is not necessarily limited to the example shown in FIGS. 8 to 10, but is shown in FIGS. 12 (a) to 12 (d). Such a shape may be used. 12A to 12D are the rear side of the female connector 101 (the upper right side in FIG. 8 and the upper side in FIG. 9A) and the front side (the lower left side in FIG. 8 and FIG. 9). (Lower side in (a)).

  In the example shown in FIG. 12A, the planar shape of the receiving terminal 153 is left-right symmetric and vertically symmetric. The receiving terminal 153 includes a base portion 153a connected to each of the left and right side edges of the terminal receiving opening 154, and is separated into a left side portion and a right side portion having a symmetric plane shape. Each of the left side portion and the right side portion includes an arm portion 153d connected to each of the upper and lower base portions 153a and a contact portion 153c connecting the tips of the upper and lower arm portions 153d, and has a vertically symmetrical plane shape.

  The terminal accommodating opening 154 includes a pair of upper and lower inner openings 154a located between the left and right arm parts 153d and a pair of left and right outer openings 154b located outside the contact part 153c. And the space | interval of the contact parts 153c which right and left oppose is narrower than the space | interval of arm parts 153d.

  The shape of the inner opening 154a is such that the width dimension gradually decreases when approaching the portion between the contact portions 153c. That is, the vicinity of the contact portion 153c at the side edge of the opposing arm portion 153d has an inclined tapered shape. Therefore, the protruding terminal 53 can smoothly enter the portion between the contact portions 153c facing each other.

  In the example shown in FIG. 12A, the protruding terminal 53 can be inserted into any of the upper and lower inner openings 154a. Therefore, when the male connector 1 and the female connector 101 are fitted, the male connector 1 and the female connector The degree of freedom of the relative position with the connector 101 is large, and the fitting operation can be easily performed. Further, since both the upper and lower sides of the contact portion 153 c are so-called doubly supported beams (flashes) supported by the arm portion 153 d, the spring force for supporting the contact portion 153 c is large, and the pair of contact portions 153 c has the protruding terminals 53. The force which elastically clamps the side surface portion 53c from both sides is large, and the contact between the side surface portion 53c and the contact portion 153c can be more reliably maintained.

  In the example shown in FIG. 12 (b), the receiving terminal 153 includes a base portion 153a connected to each of the left and right side edges of the terminal receiving opening 154, and a left side portion and a right side portion having a bilaterally symmetric planar shape. Have been separated. Each of the left part and the right part includes an arm part 153d connected to each of the upper and lower base parts 153a and a contact part 153c that connects the tips of the upper and lower arm parts 153d, but the planar shape is not vertically symmetrical. .

  The upper base portion 153a1 is located near the upper edge of the terminal accommodating opening 154, while the lower base portion 153a2 is located substantially in the middle of the upper and lower sides of the terminal accommodating opening 154. The contact portion 153c exists at a position closer to the lower side than the upper and lower middles of the terminal accommodating opening 154. In addition, the planar shape of the upper arm portion 153d1 is a substantially straight or a large bent shape, but the planar shape of the lower arm portion 153d2 is a slightly curved J shape or U shape. The inner opening 154a is positioned between the left and right upper arm portions 153d1.

  The shape of the inner opening 154a is such that the width dimension gradually decreases when approaching the portion between the contact portions 153c. That is, the vicinity of the contact portion 153c at the side edge of the opposing arm portion 153d has an inclined tapered shape. Therefore, the protruding terminal 53 can smoothly enter the portion between the contact portions 153c facing each other.

  In the example shown in FIG. 12B, since the upper side of the inner opening 154a is larger than the lower side, it is possible to make one (upper) inner opening 154a larger than in the example shown in FIG. In addition, when the male connector 1 and the female connector 101 are fitted, the relative position between the male connector 1 and the female connector 101 is large, and the fitting operation can be easily performed. Further, if the size of the upper inner opening 154a is made equal to the example shown in FIG. 12A, the entire size of the terminal accommodating opening 154 can be reduced, and the terminal accommodating opening 154 and the receiving terminal 153 can be reduced. The arrangement density can be increased. Furthermore, since the upper and lower arm portions 153d are long, so-called spring lengths are long, the range in which the contact portion 153c can be elastically displaced is widened, and the width dimension of the side surface portion 53c of the protruding terminal 53 is changed over a wide range. Therefore, the contact between the side surface portion 53c and the contact portion 153c can be more reliably maintained.

  In the example shown in FIGS. 12C and 12D, the receiving terminal 153 includes a base portion 153a connected to each of the left and right side edges of the terminal receiving opening 154, and has a left and right symmetrical plane shape. And the right part. Each of the left part and the right part includes an arm part 153d connected to each of the upper and lower base parts 153a and a contact part 153c that connects the tips of the upper and lower arm parts 153d, but the planar shape is not vertically symmetrical. .

  The upper base portion 153a1 is located near the upper edge of the terminal accommodating opening 154, and the lower base portion 153a2 is located near the lower edge of the terminal accommodating opening 154. The contact portion 153c exists at a position closer to the lower side than the upper and lower middles of the terminal accommodating opening 154. In addition, the planar shape of the upper arm portion 153d1 is a substantially straight or a large bent shape, but the planar shape of the lower arm portion 153d2 is a slightly curved S shape or N shape. The inner opening 154a is positioned between the left and right upper arm portions 153d1.

  In the example shown in FIGS. 12C and 12D, the length of the lower arm portion 153d2 is longer than that in the example shown in FIG. 12B, so that the spring length is longer and the side surface of the protruding terminal 53 is longer. A wider range of changes in the width dimension of the portion 53c can be accommodated. The other points are the same as in the example shown in FIG.

  Next, an operation of fitting the male connector 1 and the female connector 101 having the above-described configuration will be described.

  FIG. 13 is a diagram showing a mating process between the male connector and the female connector in the first embodiment of the present invention, and FIG. 14 is a mating process between the male connector and the female connector in the first embodiment of the present invention. FIG. 15 is a three-plane view showing a state in which the mating process between the male connector and the female connector in the first embodiment of the present invention is completed, and FIG. 16 is a first view of the present invention. It is a principal part enlarged view which shows the state which the fitting process of the male connector and female connector in embodiment completed, and is the F section enlarged view in FIG.15 (c). In addition, in FIG. 13, (a)-(c) is a figure which shows each process, In FIG. 15, (a) is a top view, (b) is a front view, (c) is a sectional side view ( It is EE arrow sectional drawing in b).

  Here, it is assumed that the female connector 101 is surface-mounted on the substrate by connecting the tail portion 158 to a connection pad formed on the surface of the substrate (not shown) by soldering or the like. The female connector 101 is mounted in such a posture that the back surface thereof faces the front surface of the substrate. In addition, the substrate is used for, for example, a personal computer, a mobile phone, a PDA, a digital camera, a video camera, a music player, a game machine, an electronic device such as a vehicle navigation device, and an electric device such as a home appliance. Although it is a circuit board, a flat circuit cable such as a flexible circuit board, a flexible flat cable, or the like, any kind of board may be used.

  First, as shown in FIG. 13A, the operator determines the posture of the male connector 1 such that the surface on which the protruding terminals 53 are formed faces the surface of the female connector 101, that is, the surface of the male connector 1 is female. The male connector 1 is positioned above the female connector 101 so as to face the surface of the connector 101 and so that the distal end portion 11a of the connecting portion 11 coincides with the inner surface of the horizontal frame portion 111a of the frame 111.

  Subsequently, the operator lowers the male connector 1 relative to the female connector 101, that is, moves the male connector 1 in the fitting direction, so that the connection portion 11 is in the connection recess 114 as shown in FIG. The surface which is the fitting surface of the male connector 1 and the surface which is the fitting surface of the female connector 101 are brought into contact with each other so that the wide portion 113 is located in the intermediate recess 13. In this case, the front end portion 11 a of the connection portion 11 is brought into contact with or close to the inner side surface of the horizontal frame portion 111 a of the frame body 111. Thereby, the connection part 11 and the connection recessed part 114 engage, and the intermediate | middle recessed part 13 and the wide part 113 engage. The left and right ear portions 21 of the connection portion 11 engage with the left and right ear accommodation recess portions 121 of the connection recess portion 114, and the insertion convex portion 56 positioned at the end of the ear portion 21 is an insertion part of the ear accommodation recess portion 121. Enter the recess 156. In addition, each of the protruding terminals 53 enters the inner opening 154 a inside the corresponding receiving terminal 153. Note that the distal end portion 11 a of the connection portion 11 is separated from the inner side surface of the horizontal frame portion 111 a of the frame body 111.

  Subsequently, the operator slides the male connector 1 in the locking direction relative to the female connector 101. That is, the male connector 1 is moved relative to the female connector 101 rearward (lower left in FIG. 13B) with the surface of the male connector 1 and the surface of the female connector 101 in contact with each other. In this case, each protruding terminal 53 enters the inner opening 154a inside the corresponding receiving terminal 153, and the insertion convex portions 56 of the left and right ear portions 21 are inserted into the insertion concave portions 156 of the left and right ear accommodating concave portions 121. Since it slides and guides in the approached state, the posture of the male connector 1 with respect to the female connector 101 is not disturbed.

  Then, as shown in FIGS. 13C and 14, when the fitting between the male connector 1 and the female connector 101 is completed, the male fitting lock portions 22 of the left and right ear portions 21 in the male connector 1 are connected to the female connector 101. The left and right wide portions 113 engage with the female fitting lock portions 122. Specifically, the male side step portion 23 of the male fitting lock portion 22 is engaged with the female step portion 123 of the female fitting lock portion 122, and the step end surface 23 a of the male side step portion 23 is engaged. In addition, the step surface 23b is in contact with or close to the step end surface 123a and the step surface 123b of the female side step portion 123. Thereby, the male connector 1 and the female connector 101 are locked, and a fitting state is maintained.

  Further, since the locking projection 156a of the insertion recess 156 locks the locking recess 56a of the insertion projection 56, the male connector 1 is prevented from sliding relative to the female connector 101 in the anti-lock direction. The Therefore, even if external force or vibration is received, the male connector 1 does not slide relative to the female connector 101 in the anti-locking direction and the lock is not released. The fitting state with the female connector 101 is maintained. Note that the force of the operator's fingers is sufficiently larger than the spring force applied to the locking projection 156a, so that when the operator slides the male connector 1 relative to the female connector 101 in the anti-lock direction. Can release the locking by releasing the locking between the locking projection 156a and the locking recess 56a.

  Furthermore, when the male connector 1 is slid relative to the female connector 101 in the locking direction, that is, rearward, the protruding terminal 53 that has entered the inner opening 154a inside the receiving terminal 153 is moved into the inner opening 154a. Are moved relative to each other and enter between the contact portions 153c facing each other as shown in FIG. As a result, the distance between the contact portions 153c is abutted against the side surface portion 53c of the protruding terminal 53 and is expanded, so that the contact portion 153c is pressed against the side surface portion 53c of the protruding terminal 53 by the spring property of the arm portion 153d. become. That is, the pair of contact portions 153c elastically sandwich the side surface portion 53c of the protruding terminal 53 from both sides. As described above, the contact portion 153c holding the side surface portion 53c of the protruding terminal 53 also contributes to maintaining the fitted state.

  Further, since the receiving terminal 153 is a thin member, and the thickness dimension of the contact portion 153c is smaller than the height dimension of the protruding terminal 53 as shown in FIG. 16, the dimensional error (tolerance) and shape of each part Even if a misalignment in the fitting direction between the male connector 1 and the female connector 101 occurs between the projecting terminal 53 and the receiving terminal 153 due to distortion or the like, all the projecting terminals 53 can cope. It surely enters the inner opening 154a inside the receiving terminal 153, and the side surface portion 53c and the contact portion 153c come into contact with each other.

  The shape of the inner opening 154a is such that the width dimension gradually decreases when approaching the portion between the contact portions 153c. That is, the width becomes narrower toward the front of the female connector 101 (lower left in FIG. 13). Further, in the example shown in the figure, the shape of the cross section of the protruding terminal 53 is a shape in which the rear of the male connector 1 (lower left in FIG. 13) is pointed. Therefore, when it moves back and approaches between the contact parts 153c which oppose, it can approach smoothly and can expand the space | interval of contact parts 153c.

  Further, the receiving terminal 153 is a thin member, and as shown in FIG. 16, the thickness dimension of the contact portion 153c is smaller than the height dimension of the protruding terminal 53, so that the receiving terminal 153 is subjected to external force or vibration. In some cases, the contact portion 153c may move in the vertical direction of the protruding terminal 53 along the side surface portion 53c. However, since the side surface portion 53c is a concave surface and includes the minimum point 53d, the position of the contact portion 153c elastically pressed by the side surface portion 53c always converges to the minimum point 53d and is separated from the minimum point 53d. Since the elastic pressing force is increased, the contact portion 153c is not separated from the side surface portion 53c. That is, since the side surface portion 53c is concave, contact between the side surface portion 53c and the contact portion 153c is reliably maintained even when subjected to external force or vibration. No interruption occurs.

  Note that the operation for releasing the fitting between the male connector 1 and the female connector 101 is only the operation opposite to the operation for fitting the male connector 1 and the female connector 101, and thus the description thereof is omitted.

  As described above, in the present embodiment, the female connector 101 as the seat connector includes the flat frame body 111 and the connection concave portion 114 defined by the frame body 111 and has a flat plate conductor on the bottom 114a. A connection recess 114 provided with a pattern 151, which fits with the male connector 1 as a mating connector, and the connection recess 114 includes a receiving terminal 153 that engages with the protruding terminal 53 of the male connector 1. Reference numeral 153 denotes a plate-like member formed by patterning the conductor pattern 151, and includes an inner opening 154 a formed inside thereof, and is connected to a portion around the receiving terminal 153 in the conductor pattern 151. A base 153a, a pair of contact parts 153c facing each other, and an arm connecting the contact part 153c and the base part 153a When the receiving terminal 153 is engaged with the projecting terminal 53, the distance between the pair of opposing contact portions 153c is smaller than the width dimension of the inner opening 154a and the projecting terminal 53. The portion 153c elastically holds the protruding terminal 53 from both sides.

  As a result, the contact between the receiving terminal 153 and the protruding terminal 53 can be stably maintained, and the occurrence of instantaneous interruption can be reliably prevented. Further, since the width of the inner opening 154a is larger than the distance between the contact portions 153c, the protruding terminal 53 can easily enter the inner opening 154a of the receiving terminal 153, and the male connector 1 and the female connector 101 The fitting operation can be easily performed.

  And the inner side opening 154a is provided with the shape which a width dimension reduces gradually, when it approaches the part between a pair of contact parts 153c. Thereby, the protruding terminal 53 can smoothly move between the contact portions 153c from the inside opening 154a.

  The base portion 153a includes an upper base portion 153a1 and a lower base portion 153a2 connected to one portion around the receiving terminal 153 and the other portion of the conductor pattern 151, and the arm portion 153d includes the contact portion 153c and the upper base portion. 153a1 and lower base portion 153a2 are connected to upper arm portion 153d1 and lower arm portion 153d2. Inner opening 154a has a portion between a pair of opposed upper arm portions 153d1 facing each other. It is larger than the portion between the side arm portions 153d2. As a result, both the upper and lower sides of the contact portion 153c are so-called doubly supported beams supported by the arm portion 153d, so that the spring force for supporting the contact portion 153c is large, and the pair of contact portions 153c elastically supports the protruding terminals 53 from both sides. Therefore, it is possible to more reliably maintain the contact between the protruding terminal 53 and the contact portion 153c. Moreover, since the upper inner opening 154a is large, when the male connector 1 and the female connector 101 are fitted, the relative position between the male connector 1 and the female connector 101 is large, and the fitting work is easy. This can be done and the arrangement density of the receiving terminals 153 can be increased.

  Furthermore, the conductor pattern 151 includes a frame existing on both the left and right sides of the receiving terminal 153, and a pair of left and right outer openings 154b positioned between the frame and the contact portion 153c or the arm portion 153d, and includes an upper base portion 153a1 and a lower base portion. 153a2 is connected to the left and right frames. Thereby, it can prevent that the receiving terminal 153 adjacent to right and left contacts. Further, the positions of the upper base portion 153a1 and the lower base portion 153a2 can be arbitrarily determined, and the degree of freedom in designing the receiving terminal 153 is increased. Further, when the receiving terminal 153 is formed by etching, the thickness of the receiving terminal 153 can be extremely reduced, and the female connector 101 can be reduced in height.

  Next, a second embodiment of the present invention will be described. In addition, about the thing which has the same structure as 1st Embodiment, the description is abbreviate | omitted by providing the same code | symbol. The description of the same operation and the same effect as those of the first embodiment is also omitted.

  FIG. 17 is an exploded view showing the layer structure of the female connector according to the second embodiment of the present invention.

  In the present embodiment, the female connector 101 is not used for connection to a power supply but is used for connection of a signal line as in the example described in the first embodiment. It is explained as a thing. In this case, as shown in FIG. 17, the conductor pattern 151 includes a wide pattern 151a and a narrow pattern 151b. The narrow pattern 151b is narrower than the first embodiment, and more There are many. And the wide pattern 151a is each arrange | positioned at the both sides of the row | line | column of the narrow pattern 151b arrange | positioned along with mutually parallel. For example, the wide pattern 151a is used as a ground line, and the narrow pattern 151b is used as a signal line.

  A receiving terminal 153 as a female terminal, which is a plurality of flat-plate terminals, is disposed in a portion corresponding to the bottom 114 a of the connection recess 114 in the conductor pattern 151. In the example shown in the figure, the receiving terminals 153 are arranged in a lattice shape and are arranged so as to form a pair of rows extending in the width direction. Specifically, in the wide pattern 151a, one receiving terminal 153 is included in each column, and in the narrow pattern 151b, one receiving terminal 153 is included in each column, and the front row (lower left side in FIG. 17). The receiving terminals 153 in the rear row and the rear row (upper right column in FIG. 17) are positioned on a straight line extending in the front-rear direction of the female connector 101. That is, the female connector 101 is arranged so as to form a rectangular planar lattice having lattice lines as axes extending in the front-rear direction and the left-right direction.

  In the first embodiment, the receiving terminals 153 in the front row and the rear row are included in the same narrow pattern 151b. However, in this embodiment, as shown in FIG. The narrow pattern 151b is separated forward and backward by a pattern separation space 152 that passes between the receiving terminal 153 in the front row and the receiving terminal 153 in the rear row. That is, one narrow pattern 151b is separated forward and backward by the pattern separation space 152, that is, the front narrow pattern 151bf and the rear narrow pattern 151br, and the receiving terminals 153 in the front row and the rear row are narrow in the front width. It is separated so as to be included in the pattern 151bf and the narrow back pattern 151br. Similarly, the wide pattern 151a is also separated into the front wide pattern 151af and the rear wide pattern 151ar by the pattern separation space 152, and the receiving terminals 153 in the front row and the rear row are included in the front wide pattern 151af and the rear wide pattern 151ar. So that they are separated.

  Thus, by separating and arranging the receiving terminals 153 not only in the width direction but also in the front-rear direction of the female connector 101, a large number of signal lines can be connected at high density. Note that the arrangement of the protruding terminals 53, which are counterpart terminals of the receiving terminals 153, is the same as the arrangement of the receiving terminals 153, but includes the protruding terminals 53 and the protruding terminals 53 here. The description of the male connector 1 is omitted.

  The front narrow pattern 151bf and the rear narrow pattern 151br separated in the front-rear direction are a front narrow tail part 158bf projecting forward as a solder tail part and a rear narrow tail part 158br projecting rearward, respectively. Is provided. The front narrow tail portion 158bf and the rear narrow tail portion 158br are connected to connection pads formed on the surface of the substrate (not shown) by soldering or the like. As a result, the female connector 101 is fixed to the board, and the front narrow pattern 151bf and the rear narrow pattern 151br including the receiving terminals 153 are individually connected to the corresponding conductive traces on the board.

  Each of the receiving terminals 153 is formed by patterning the conductor pattern 151 by, for example, a method such as etching using a photolithography technique, as in the first embodiment. Therefore, the thickness dimension of the receiving terminal 153 is equivalent to the thickness dimension of the conductor pattern 151.

  The base film 115 is the same member as the base film 115 of the first embodiment, and the base film 115 is thickened at portions corresponding to the receiving terminals 153 and the insertion recesses 156 formed in the conductor pattern 151. A terminal corresponding opening 115a and a recess corresponding opening 115b penetrating in the vertical direction are formed. Note that the receiving terminals 153 in the present embodiment form a pair of rows extending in the width direction, and the receiving terminals 153 in the front row and the rear row are separated, so that each of the terminal corresponding openings 115a is also a receiving terminal. In order to correspond to each of 153, they are individually separated and arranged so as to form a rectangular planar lattice having lattice lines as axes extending in the front-rear direction and the left-right direction of the female connector 101.

  The cover film 117 is the same member as the cover film 117 of the first embodiment, but the range of the terminal corresponding opening 117a and the recess corresponding opening 117b provided in the cover film 117 of the first embodiment. A large single central opening 117c is formed so as to include all of the above.

  Next, the planar shape of the receiving terminal 153 in the present embodiment will be described.

  FIG. 18 is a first top view showing an example of a female terminal of a female connector in the second embodiment of the present invention, and FIG. 19 shows an example of a female terminal of the female connector in the second embodiment of the present invention. FIG. 20 is a third top view showing an example of the female terminal of the female connector in the second embodiment of the present invention, and FIG. 21 is a diagram of the female connector in the second embodiment of the present invention. It is a 4th top view which shows the example of a female terminal.

  The receiving terminal 153 in the present embodiment may have a planar shape similar to that of the receiving terminal 153 in the first embodiment, but has a planar shape as shown in FIGS. Will be described. 18 to 21 correspond to the rear side (upper right side in FIG. 17) and the front side (lower left side in FIG. 17) of the female connector 101.

  In the example shown in FIGS. 18A to 18D, the receiving terminal 153 is not housed in the terminal housing opening 154. For example, the receiving terminal 153 is formed by patterning the conductor pattern 151 by a method such as etching using a photolithography technique, but the rear end side or the rear narrow pattern of the narrow front narrow pattern 151bf. Since it is formed on the front end side of 151br, no material that forms a frame is left around the portion where the material around the receiving terminal 153 has been removed by patterning. As described above, the receiving terminals 153 are not received in the terminal receiving openings 154, that is, there are no frames around the receiving terminals 153 or on the left and right sides, so that the interval between the receiving terminals 153 adjacent to the left and right can be reduced. The arrangement density of the receiving terminals 153 in the left-right direction of the female connector 101 can be increased, and the width dimension of the female connector 101 can be shortened.

  In addition, none of the examples shown in FIGS. 18A to 18D is vertically symmetric, and strictly speaking, neither is left-right symmetric. Note that the examples shown in FIGS. 18A to 18D are all assumed to be formed on the front end side of the rear narrow pattern 151br.

  In the example shown in FIG. 18A, the receiving terminal 153 is an upper end portion 153e1 which is a portion connected to the main body of the rear narrow pattern 151br and a portion corresponding to the front end portion of the rear narrow pattern 151br. A lower end 153e2 is included. The upper end portion 153e1 and the lower end portion 153e2 correspond to portions around the receiving terminals 153 in the conductor pattern 151. The upper end portion 153e1 has a substantially L-shaped shape with a lower right portion missing, and a left portion and an upper base portion 153a1 of the right portion are connected to the right side of a portion extending vertically. Further, the lower base portion 153a2 of the left side portion and the right side portion are gathered at the center in the width direction so as to be integrated with the left and right sides, and connected to the upper side of the lower end portion 153e2.

  The planar shapes of the lower arm portion 153d2 and the contact portion 153c of the left and right portions are symmetrical. The planar shape of the lower arm portion 153d2 is such that a small bent L shape and a J shape are combined. Further, the planar shape of the upper arm portion 153d1 on the right side portion is a substantially straight or a bent shape, but the planar shape of the upper arm portion 153d1 on the left side portion is a shape in which an L shape is further added. is there. The upper base portion 153a1, the lower arm portion 153d2, and the contact portion 153c have a narrow strip shape, but the upper arm portion 153d1 has a wide strip shape.

  The contact portion 153c exists at a position closer to the lower side than the upper and lower middles of the terminal accommodating opening 154. The inner opening 154a is positioned between the left and right upper arm portions 153d1. The shape of the inner opening 154a is such that the width dimension gradually decreases when approaching the portion between the contact portions 153c. That is, the vicinity of the contact portion 153c at the side edge of the opposing upper arm portion 153d1 has an inclined tapered shape. Therefore, the protruding terminal 53 can smoothly enter the portion between the contact portions 153c facing each other. Further, an outer space 154c, which is a relatively large space, is formed outside the left and right contact portions 153c, and the outer space 154c absorbs the displacement of the contact portion 153c in the outer direction. Therefore, even if the protruding terminal 53 enters the portion between the contact portions 153c facing each other and the contact portion 153c is displaced outward, it does not come into contact with other receiving terminals 153 adjacent in the left-right direction.

  In the example shown in FIG. 18 (a), the contact portion 153c is located at the lower position, so that the inner opening 154a between the left and right upper arm portions 153d1 can be enlarged, and the male connector 1 and the female connector 101 When mating, the degree of freedom of the relative position between the male connector 1 and the female connector 101 is large, and the mating operation can be easily performed. Further, at least one of the upper base portion 153a1 having the shorter upper arm portion 153d1 and the upper base portion 153a1 on the left side in the example shown in FIG. Therefore, the stress received by the upper arm 153d1 or the upper base 153a1 when the protruding terminal 53 enters the terminal accommodating opening 154 can be dispersed. Further, since the lower arm portion 153d2 is long, so-called spring length is long, the range in which the contact portion 153c can be elastically displaced is widened, and the width dimension of the side surface portion 53c of the protruding terminal 53 is changed in a wide range. Therefore, the contact between the side surface portion 53c and the contact portion 153c can be more reliably maintained.

  Also in the example shown in FIG. 18B, the receiving terminal 153 includes an upper end portion 153e1 and a lower end portion 153e2, similarly to the example shown in FIG. 18A. The upper end portion 153e1 has a substantially rectangular shape, and a left portion and an upper base portion 153a1 of the right portion are connected to the right side of a portion extending vertically. Further, the lower base portion 153a2 of the left side portion and the right side portion are gathered at the center in the width direction so as to be integrated with the left and right sides, and connected to the upper side of the lower end portion 153e2. Further, the planar shapes of the other portions, that is, the upper arm portion 153d1, the lower arm portion 153d2, the contact portion 153c, the upper base portion 153a1, and the lower base portion 153a2 are substantially the same as the example shown in FIG. However, the following three points are different from the example shown in FIG.

  First, in the example shown in FIG. 18B, the upper arm portion 153d1 is formed wider than the example shown in FIG. Second, in the example shown in FIG. 18B, the length of the lower arm 153d2 in the vertical direction is shorter than that in the example shown in FIG. Third, in the example shown in FIG. 18B, a linear bridge portion 153f that passes through the outside of the contact portion 153c and connects the upper arm portion 153d1 and the lower arm portion 153d2 is formed.

  By having these three points, the spring strength of the upper arm portion 153d1, the lower arm portion 153d2, the contact portion 153c, the upper base portion 153a1, and the lower base portion 153a2 as a whole, that is, the receiving terminal 153 is improved. Accordingly, the force by which the contact portion 153c clamps the side surface portion 53c of the protruding terminal 53 from both sides is improved, and the contact pressure between the contact portion 153c and the side surface portion 53c is increased, so that the contact state between the receiving terminal 153 and the protruding terminal 53 is increased. Is more stable. Further, excessive bending (bending) of each part of the receiving terminal 153 is prevented, and contact between the receiving terminals 153 adjacent in the left-right direction is reliably prevented.

  Since the configuration and effects of other points are the same as the example shown in FIG. 18A, the description thereof is omitted.

  In the example shown in FIG. 18C, the upper end portion 153e1 has a substantially rectangular shape, and the upper base portion 153a1 of the right portion is connected to the right side of the vertically extending portion, and the portion extending to the left and right The upper base 153a1 of the left part is connected to the lower side. Further, the upper base portion 153a1 does not have a crank-like planar shape and is substantially linear. Except for the width and length of each part, the configuration and effects of other points are the same as in the example shown in FIG.

  The example shown in FIG. 18 (d) is the same as the example shown in FIG. 18 (a) except for the width and length of each part, and the description thereof will be omitted. .

  In the example shown in FIGS. 19A to 19C, the receiving terminal 153 is not accommodated in the terminal accommodating opening 154 as in the examples shown in FIGS. 18A to 18D. There is no frame around or on the left and right of the receiving terminal 153. In addition, none of the examples shown in FIGS. 19A to 19C is vertically symmetric and left-right symmetric. The examples shown in FIGS. 19A to 19C are all formed on the front end side of the rear narrow pattern 151br, as in the examples shown in FIGS. 18A to 18D. It will be explained as a thing.

  In the example shown in FIG. 19A, the receiving terminal 153 is an upper end portion 153e1 which is a portion connected to the main body of the rear narrow pattern 151br and a portion corresponding to the front end portion of the rear narrow pattern 151br. A lower end 153e2 is included. The upper end portion 153e1 has a substantially rectangular shape, and a left portion and an upper base portion 153a1 of the right portion are connected to a portion extending to the left and right. The lower end portion 153e2 has a substantially rectangular shape, and the lower base portion 153a2 of the right side portion is connected to the right end of the left and right portions thereof, but the lower base portion 153a2 of the left side portion is connected. Absent. In the example shown in FIG. 19A, the lower base portion 153a2, which is the second base portion of the left portion, is connected to the upper end portion 153e1 outside the upper base portion 153a1.

  In the right side portion, the upper arm portion 153d1 has a substantially curved “H” -shaped planar shape, and its upper end is connected to the upper base portion 153a1. The lower arm 153d2 has a substantially S-shaped planar shape, and the lower end thereof is connected to the lower base 153a2. The lower end of the upper arm portion 153d1 and the upper end of the lower arm portion 153d2 are connected by a contact portion 153c. The contact portion 153c is located approximately in the middle between the upper end portion 153e1 and the lower end portion 153e2.

  On the other hand, in the left part, the upper arm part 153d1 has a plane shape symmetrical to the upper arm part 153d1 in the right part, and its upper end is connected to the upper base part 153a1, and its lower end is connected to the upper end of the contact part 153c. . The contact portion 153c faces the contact portion 153c on the right side portion. The lower arm portion 153d2 has a substantially J-shaped planar shape, the upper end of the long portion is connected to the lower base portion 153a2 that is the second base portion, and the upper end of the short portion is the lower end of the contact portion 153c. It is connected to the. That is, the left portion has a substantially U-shaped planar shape as a whole, and is connected to the upper end portion 153e1 at two points of the upper base portion 153a1 and the lower base portion 153a2, and is not connected to the lower end portion 153e2.

  In the example shown in FIG. 19A, the lower arm 153d2 on the left side and the lower end 153e2 are open to communicate with the outer space 154c. Therefore, not only from the inner opening 154a between the left and right upper arm portions 153d1, but also from between the lower end and the lower end portion 153e2 of the lower arm portion 153d2 of the left side portion, Since the male connector 1 and the female connector 101 can be fitted together, the relative position between the male connector 1 and the female connector 101 is large, and the fitting work is easy. It can be carried out. Further, since the upper base portion 153a1 and the upper arm portion 153d1 are narrower than those in FIGS. 18A to 18D, and the left side portion is not connected to the lower end portion 153e2, a so-called cantilever state is obtained. High flexibility. Accordingly, the range in which the contact portion 153c can be elastically displaced is widened, and it is possible to cope with a wide range of changes in the width dimension of the side surface portion 53c of the protruding terminal 53, and the contact between the side surface portion 53c and the contact portion 153c is further improved. It can be reliably maintained.

  The configuration and effects of other points are the same as in the example shown in FIGS. 18A to 18D, and thus the description thereof is omitted.

  In the example shown in FIG. 19B, the right side portion and the left side portion of the receiving terminal 153 are connected to the upper end portion 153e1 and the lower end portion 153e2. The upper end portion 153e1 and the lower end portion 153e2 have a substantially rectangular planar shape, and an upper base portion 153a1 and a lower base portion 153a2 of the right side portion and the left side portion are connected to left and right ends thereof. Further, the left and right contact portions 153c facing each other are positioned approximately in the middle between the upper end portion 153e1 and the lower end portion 153e2.

  In the right portion, the upper arm portion 153d1 has a planar shape that combines a straight line and a U-shape, and has an upper end connected to the upper base portion 153a1 and a lower end connected to the contact portion 153c. The lower arm 153d2 also has a planar shape that combines a straight line and a U-shape, and has an upper end connected to the contact portion 153c and a lower end connected to the lower base 153a2.

  On the other hand, in the left side portion, the upper arm portion 153d1 has a planar shape that combines a straight line and a U-shape, and has an upper end connected to the upper base portion 153a1 and a lower end connected to the contact portion 153c. The lower arm portion 153d2 has a planar shape that combines an L shape and a U shape, and has an upper end connected to the contact portion 153c and a lower end connected to the lower base portion 153a2.

  The U-shaped portion of the upper arm portion 153d1 and the lower arm portion 153d2 in the left portion is located above the U-shaped portion of the upper arm portion 153d1 and the lower arm portion 153d2 in the right portion, and In the left part, the parts that bulge out like a U-shape are nested in each other and protrude inward in the width direction. The configuration and effects of other points are the same as in the example shown in FIG.

  In the example shown in FIG. 19 (c), the upper arm portion 153d1 on the right side portion has a shape such as a combination of L shape and the lower arm portion 153d2 on the left side portion is also L shape. It has a shape that is combined with the character.

  Since the configuration and effects of other points are the same as the example shown in FIG. 19B, the description thereof is omitted.

  In the example shown in FIGS. 20A and 20B, the receiving terminal 153 is housed in the terminal housing opening 154, similar to the example shown in FIGS. There is a frame around or on the left and right of the receiving terminal 153. In addition, the examples shown in FIGS. 20A and 20B are both symmetrical, but not vertically symmetrical. Note that the examples shown in FIGS. 20A and 20B are formed on the front end side of the rear narrow pattern 151br, as in the examples shown in FIGS. It will be explained as a thing.

  In the example shown in FIG. 20 (a), the receiving terminal 153 includes a base portion 153a connected to each of the left and right side edges of the terminal receiving opening 154, and a left side portion and a right side portion having a left-right symmetric planar shape. Have been separated. Each of the left part and the right part includes an arm part 153d connected to each of the upper and lower base parts 153a and a contact part 153c that connects the tips of the upper and lower arm parts 153d, but the planar shape is not vertically symmetrical. .

  The upper base portion 153a1 is located near the upper edge of the terminal accommodating opening 154, while the lower base portion 153a2 is located substantially in the middle of the upper and lower sides of the terminal accommodating opening 154. The contact portion 153c exists at a position closer to the lower side than the upper and lower middles of the terminal accommodating opening 154. In addition, the planar shape of the upper arm portion 153d1 is a substantially straight or a large bent shape, but the planar shape of the lower arm portion 153d2 is a slightly curved J shape or U shape. The inner opening 154a is positioned between the left and right upper arm portions 153d1.

  The shape of the inner opening 154a is such that the width dimension gradually decreases when approaching the portion between the contact portions 153c. That is, the vicinity of the contact portion 153c at the side edge of the opposing arm portion 153d has an inclined tapered shape. Therefore, the protruding terminal 53 can smoothly enter the portion between the contact portions 153c facing each other.

  In the example shown in FIG. 20A, since the upper side of the inner opening 154a is larger than the lower side, one (upper) inner opening 154a can be enlarged, and the male connector 1 and the female connector 101 are fitted. In this case, the relative position between the male connector 1 and the female connector 101 is large, and the fitting operation can be easily performed. Further, the overall size of the terminal accommodating openings 154 can be reduced, and the arrangement density of the terminal accommodating openings 154 and the receiving terminals 153 can be increased. Furthermore, since the upper and lower arm portions 153d are long, so-called spring lengths are long, the range in which the contact portion 153c can be elastically displaced is widened, and the width dimension of the side surface portion 53c of the protruding terminal 53 is changed over a wide range. Therefore, the contact between the side surface portion 53c and the contact portion 153c can be more reliably maintained. Further, compared with the example shown in FIG. 12B, the width of the upper arm portion 153d1 and the lower arm portion 153d2 is narrow, so that the flexibility is high and the range in which the contact portion 153c can be elastically displaced is wide. Therefore, it is possible to cope with a wide range of changes in the width dimension of the side surface portion 53c of the protruding terminal 53, and it is possible to more reliably maintain contact between the side surface portion 53c and the contact portion 153c.

  The configuration and effects of other points are the same as in the example shown in FIG.

  In the example shown in FIG. 20B, the receiving terminal 153 has the same dimension in the width direction as the example shown in FIG. 20A, whereas the dimension in the vertical direction is shown in FIG. Larger than the example. That is, as compared with the example shown in FIG. 20A, the dimensions of the respective portions of the receiving terminal 153 are elongated in the vertical direction. Therefore, the flexibility is higher, the range in which the contact portion 153c can be elastically displaced is wider, and it is possible to cope with a wider range of changes in the width dimension of the side surface portion 53c of the protruding terminal 53. The contact with the contact portion 153c can be more reliably maintained.

  In addition, about the structure and effect of another point, since it is the same as that of the example shown by Fig.20 (a), the description is abbreviate | omitted.

  In the example shown in FIGS. 21A to 21D, the receiving terminal 153 is housed in the terminal housing opening 154, similar to the example shown in FIGS. 20A and 20B. There is a frame around or on the left and right of the receiving terminal 153. In addition, all of the examples shown in FIGS. 21A to 21D are neither left-right symmetric nor vertically symmetric. Note that the examples shown in FIGS. 21A to 21D are formed on the front end side of the rear narrow pattern 151br, as in the examples shown in FIGS. 20A and 20B. It will be explained as a thing.

  In the example shown in FIG. 21A, the upper base portion 153a1 and the lower base portion 153a2 are connected to the side edges near the upper edge and the lower edge of the terminal accommodating opening 154. The base 153a1 is connected to the left edge, and the lower base 153a2 is connected to the right edge.

  In the right part, the upper base 153a1 has an L-shaped planar shape, and the upper arm 153d1 is connected to the lower end thereof. The upper arm portion 153d1 is provided with a substantially bent square shape, and a contact portion 153c is connected to the lower end of the upper arm portion 153d1. And the lower arm part 153d2 provided with the planar shape which combined the letter B and the J character bent greatly is connected to the lower end of this contact part 153c. Further, a lower base portion 153a2 having a substantially P-shaped or hook-shaped planar shape is connected to the lower end of the lower arm portion 153d2.

  On the other hand, in the left part, the upper base 153a1 has a substantially P-shaped or bowl-shaped planar shape, and the upper arm 153d1 is connected to one end. The upper arm portion 153d1 has a planar shape that is a combination of a substantially bent square shape and a P shape, and a contact portion 153c is connected to the lower end thereof. And the lower arm part 153d2 provided with the plane shape of the shape of a large bend at the lower end of the contact part 153c is connected. Further, a lower base portion 153a2 having an L-shaped planar shape is connected to the lower end of the lower arm portion 153d2.

  The terminal accommodating opening 154 includes a pair of upper and lower inner openings 154a located between the left and right arm parts 153d and a pair of left and right outer openings 154b located outside the contact part 153c. And the space | interval of the contact parts 153c which right and left oppose is narrower than the space | interval of arm parts 153d.

  The contact portion 153c exists at a position closer to the lower side than the upper and lower middles of the terminal accommodating opening 154. The inner opening 154a is positioned between the left and right upper arm portions 153d1. The shape of the inner opening 154a is such that the width dimension gradually decreases when approaching the portion between the contact portions 153c. That is, the vicinity of the contact portion 153c at the side edge of the opposing upper arm portion 153d1 has an inclined tapered shape. Therefore, the protruding terminal 53 can smoothly enter the portion between the contact portions 153c facing each other.

  In the example shown in FIG. 21A, since the upper side of the inner opening 154a is larger than the lower side, the upper inner opening 154a can be enlarged, and when the male connector 1 and the female connector 101 are fitted, The degree of freedom of the relative position between the male connector 1 and the female connector 101 is large, and the fitting operation can be easily performed. 20A and 20B, the upper base portion 153a1 and the lower base portion 153a2 have an elongated planar shape, so that the flexibility is high and the protruding terminal 53 is located in the terminal receiving opening 154. The stress received by the upper arm portion 153d1 or the upper base portion 153a1 when entering the space can be dispersed.

  In addition, about the structure and effect of another point, since it is the same as that of the example shown by Fig.20 (a) and (b), the description is abbreviate | omitted.
