Description

  The present invention relates to a connector for connecting a thin plate-like connection object such as an FPC or FFC.

Patent Document 1 is a conventional example of a connector capable of connecting a thin plate-like connection object (FPC, FFC, etc.).
This connector has a thin plate-like connection object that can be inserted and removed, an insulator placed on a circuit board, a plurality of contacts that are fixed in line with the insulator and that come into contact with the connection object inserted into the insulator, and can rotate to the insulator And a cover member rotatably supported by the insulator. One end portion of each contact in the longitudinal direction is a tail portion that protrudes outside the insulator and is soldered to the circuit board.

The actuator can rotate between an unlock position that is substantially orthogonal to the insertion / removal direction of the connection object and a lock position that falls to the escape direction side of the connection object and increases the contact pressure between the connection object and the contact. is there.
The cover member is between an open position that exposes the tail portion of the contact substantially perpendicular to the insertion / removal direction of the connection target and a closed position that falls on the opposite side of the connection target and covers the tail portion. It is possible to prevent the dust and the dust from adhering to the tail part by covering the tail part of each contact with the cover member.

Japanese Patent No. 4262665

  This connector can be mounted on a circuit board using suction means. That is, the upper surface of the cover member positioned at the open position is adsorbed by the suction means located above the connector, and by moving this suction means, the tail portion of each contact is placed on the solder paste applied on the circuit board ( The connector is placed on the circuit board), and each solder paste is heated and melted in a reflow furnace, thereby mounting (soldering) on the circuit board.

In order to suck the cover member by the suction means, it is necessary to form a flat suction surface having a certain size on the surface of the cover member. However, since this type of connector has been downsized in recent years, the cover member has also been downsized. Therefore, it is difficult to form a sufficiently large suction surface on the surface of the cover member.
Further, when the cover member is downsized, it is not easy for the operator to rotate the cover member by hand.

  An object of the present invention is to provide a connector capable of reliably adsorbing a cover member by suction means and capable of easily rotating the cover member even when the connector is small.

The connector of the present invention is capable of contacting an insulator in which a thin plate-like connection object can be inserted and removed, and the connection object inserted into the insulator, and has an insulator at an end opposite to the escape direction of the connection object. A contact supported by the insulator having a tail portion that is electrically connected to the circuit board at a peripheral portion, an open position that exposes the tail portion substantially perpendicular to the circuit board, and the tail that is tilted toward the tail portion side A connector that includes a closed position that covers a portion and a cover member that is supported by the insulator so as to be rotatable between the circuit board and the suction member that is substantially parallel to the circuit board when the cover member is positioned at the open position. A flat suction surface that can be adsorbed by means, and substantially parallel to the circuit board when positioned at the open position, and one surface is continuous with the flat suction surface And a gripping protrusion constituting the extension plane that, further the connector, and a locking position lying in the exit direction increasing the contact pressure of the connection object and the contact, in the opposite side from the locking position An actuator that is supported by the insulator so as to be rotatable between the rotated and unlocked positions and that is positioned on the escape direction side of the cover member, and the unlock position when the cover member is located at the open position. It is characterized by comprising an unlock holding portion that engages with the actuator located at the position and holds the actuator in the unlock position .

The unlock holding portion may be formed on the gripping protrusion.
In this way, if the gripping means also serves as the unlock holding portion, the configuration of the cover member can be simplified.

The cover member may be provided with an inclined support surface that can fall on the opposite side with respect to a plane orthogonal to the insertion / removal direction when the cover member is located at the open position and can support the actuator.
When the cover member is located at the open position, the inclined support surface formed on the cover member falls to the side opposite to the escape direction with respect to the plane orthogonal to the insertion / removal direction of the connection object. Therefore, if the actuator rotated to the unlock position is supported by the inclined support surface, the unlock position of the actuator can be adjusted even when the connector is small (when the dimension of the connection target is small). The position can be set to a position that is greatly rotated from the lock position (a position that is tilted to the side opposite to the escape direction with respect to the plane). Therefore, when the actuator is located at the unlock position, the connection object can be smoothly inserted into and removed from the insulator.

You may provide the open position holding means which hold | maintains the said cover member in the said open position.
If comprised in this way, a cover member can be reliably hold | maintained in an open position. Accordingly, when the actuator and the unlock holding means are provided, the actuator is more reliably held at the unlock position by the cover member.

In the present invention, since the gripping protrusion is formed on the cover member, it is easy for the operator to rotate the cover member by hand even when the cover member (connector) is small. By rotating to the closed position, dust and dust can be easily prevented from adhering to the tail portion.
Moreover, since the cover member is provided with a gripping protrusion, a large suction surface composed of a flat suction surface and an extension plane is formed on the cover member, so that it is larger than a conventional cover member that does not have a gripping protrusion (extension plane). An adsorption surface can be formed. Therefore, even if the cover member (connector) is small, the cover member can be reliably adsorbed by the suction means.
Furthermore, the contact pressure between the connection object and the contact can be increased by rotating the actuator to the lock position side. Moreover, the actuator can be reliably held at the unlock position by the unlock holding portion of the cover member.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. In the following description, front and rear, left and right, and up and down directions are based on the directions of arrows in the figure.
The connector 10 of this embodiment includes an insulator 20, a signal contact 40, an actuator 50, a fixing bracket 60, and a cover member 70 as large components.
The insulator 20 is formed by injection molding an insulating and heat resistant synthetic resin material. An FPC insertion groove 21 having substantially the same width as the FPC 80 is formed in the front portion of the upper surface of the insulator 20. The front surface and the upper surface of the front portion of the FPC insertion groove 21 are open, and the rear portion of the FPC insertion groove 21 extends to the inside of the insulator 20 (see FIGS. 5 and 7). A pair of side walls 22 located on the left and right sides of the FPC insertion groove 21 are formed on the left and right sides of the front portion of the insulator 20, and a retaining recess 23 that is recessed downward is formed on the upper surface of the rear half of the side wall 22. It is provided. A front end cutout 24 is formed on the inner surface of the front half of the left and right side walls 22. The bottom surface of the front end notch 24 is a horizontal support plane 25, and a lock holding groove 26 whose front surface is open is formed on the side surface of the front end notch 24. Further, metal fitting fixing grooves 28 are recessed in the upper surfaces of the left and right side walls 22. As shown in the drawing, the front end of the metal fitting fixing groove 28 is open at the front end surface of the side wall 22. Further, the metal fitting fixing groove 28 extends to the bottom surface of the retaining recess 23 and the inside of the rear portion of the insulator 20 (see FIGS. 2 and 8). Seven support protrusions 30 project forward from the front half of the upper half of the rear portion of the insulator 20 (the part located above the FPC insertion groove 21). A groove 31 is recessed (see FIG. 5). Shaft insertion grooves (opening position holding means) 32 extending forward are respectively recessed in the left and right side portions of the rear end surface of the insulator 20, and walls (protrusions) are formed in the front and rear sides of the inner surface of the shaft insertion groove 32. ) And an inner shaft support groove 33 having an open upper surface is recessed (see FIGS. 1, 2, 8, 10, and 11). Further, a leg receiving groove 34 is formed in a portion adjacent to the inner shaft support groove 33 on the upper surface of the insulator 20 so as to extend downward and communicate with the shaft insertion groove 32 and open on the rear surface. In addition, a total of 28 contact insertion grooves 35 extending in the front-rear direction are formed in the insulator 20. The rear part of each contact insertion groove 35 penetrates the rear part of the insulator 20 in the front-rear direction, and the front part of each contact insertion groove 35 is recessed on the bottom surface of the FPC insertion groove 21.

A total of 28 signal contacts 40 were formed by processing a thin plate of a copper alloy (for example, phosphor bronze, beryllium copper, titanium copper) or a Corson copper alloy having spring elasticity into a shape shown in the drawing using a progressive die (stamping). The surface is formed by nickel plating on the surface, and then gold plating is applied.
As shown in FIGS. 1, 2, 6, and the like, a tail portion 41 bent in a substantially L shape is formed at the rear end portion of the signal contact 40. Further, the front portion of the signal contact 40 is an elastic deformation portion 42 extending obliquely upward in the front direction, and a contact protrusion 43 bent upward is formed in the vicinity of the front end of the elastic deformation portion 42.
Each signal contact 40 is press-fitted from the rear into each contact insertion groove 35 of the insulator 20. As shown in FIG. 6, when each signal contact 40 is press-fitted into the contact insertion groove 35, the elastic deformation portion 42 is positioned in the FPC insertion groove 21, and the lower surface of the intermediate portion positioned between the tail portion 41 and the elastic deformation portion 42. Comes into contact with the bottom surface of the corresponding contact insertion groove 35, and further, the locking projection provided on the side surface of the intermediate portion bites into the side surface of the corresponding contact insertion groove 35, so that the intermediate portion is fixed to the contact insertion groove 35. It becomes a state. On the other hand, the tail portion 41 projects rearward of the insulator 20, and the lower surface thereof is located below the lower surface of the insulator 20.

The rotary actuator 50, which is a plate-like member extending in the left-right direction, is obtained by injection-molding a heat-resistant synthetic resin material using a metal mold. At the lower ends of the left and right sides of the actuator 50, there are projecting rotation support shafts 51 extending leftward and rightward and coaxial with each other. Seven cam portions 52 project from the lower end portion of the actuator 50, and locked shafts 53 that are coaxial with the rotation support shaft 51 project from both side surfaces of each cam portion 52. Lock holding surfaces 54 are formed on the left and right sides of the surface of the actuator 50 (the front surface in FIGS. 1 and 2), and the space between the left and right lock holding surfaces 54 is larger than that of the lock holding surface 54 (FIG. 1). A pressing protrusion 55 is formed which protrudes forward in FIG. 2 and has a flat surface. Further, locking engaging portions 56 project outwardly from the tip portions (upper portions in FIGS. 1 and 2) on both side surfaces of the actuator 50. An unlock holding engagement groove 57 extending in the left-right direction is formed in the center in the width direction of the tip of the actuator 50 (the upper portion in FIGS. 1 and 2). Further, a flat auxiliary suction surface 58 is formed on the back surface of the actuator 50 (the rear surface in FIGS. 1 and 2).
The pair of left and right fixing brackets 60 is a metal plate press-molded product, and has a bowl-shaped tail portion 61 projecting from the lower end portion on the front side, a press-fit portion 62 projecting from the rear end surface, and an intermediate projecting portion projecting upward. 63.

The actuator 50 and the fixture 60 are attached to the insulator 20 by the following procedure.
First, as shown in FIGS. 1 and 2, the lower end portion of the actuator 50 that is substantially orthogonal to the insulator 20 is inserted into the FPC insertion groove 21 from the front, and each cam portion 52 is adjacent to the support protrusion of the insulator 20. The left and right rotation support shafts 51 are placed on the bottom surfaces of the left and right retaining recesses 23 (not shown). At this time, each locked shaft 53 of the actuator 50 is positioned below each bearing groove 31 (not shown), but when the actuator 50 is moved upward with respect to the insulator 20, each locked shaft 53 corresponds. The left and right rotation support shafts 51 are spaced upward from the bottom surface of the retaining recess 23 (see FIG. 8).
Next, the actuator 50 is held in this state by an assembly device (not shown), and the fixing bracket 60 is press-fitted into the left and right bracket fixing grooves 28 from the front. Then, the tail portion 61 engages with the front edge portion of the metal fitting fixing groove 28, and the press-fit portion 62 is press-fitted into the rear end portion of the metal fitting fixing groove 28, and the locking projection protruding from the upper surface of the press-fit portion 62 fixes the metal fitting. Since it bites into the upper surface of the rear end portion of the groove 28, the longitudinal movement and the vertical movement of the fixing bracket 60 with respect to the insulator 20 are restricted. Further, since the intermediate protrusion 63 is positioned in the retaining recess 23 and the upper end surface of the intermediate protrusion 63 supports the left and right rotation support shafts 51 from below (see FIG. 8), the holding of the actuator 50 by the assembly device is released. Even so, each locked shaft 53 maintains engagement with the front end portion of the corresponding bearing groove 31. Further, the lower surface of the tail portion 61 is located on the same plane as the lower surface of the tail portion 41.
The actuator 50 and the fixing bracket 60 can be attached to the insulator 20 in an inverted state in which the insulator 20 is turned upside down. In this case, since each of the locked shafts 53 is engaged with the front end portion of the corresponding bearing groove 31 by its own weight, the holding of the actuator 50 by the assembling apparatus can be omitted.

  When the actuator 50 is attached to the insulator 20 in this way, each locked shaft 53 engages with the front end portion of the bearing groove 31 (see FIG. 5), and the left and right rotation support shafts 51 are moved rearward. Since it is regulated by the rear wall of the corresponding retaining recess 23 (see FIGS. 3 and 8), the longitudinal movement of the actuator 50 with respect to the insulator 20 at the base end (lower end in FIGS. 1 and 2) is regulated. . Further, the upward movement of each of the locked shafts 53 is restricted by the bearing groove 31 and the downward movement of the left and right rotation support shafts 51 is restricted by the fixing bracket 60 (intermediate protrusion 63). The vertical movement of the end portion with respect to the insulator 20 is also restricted. Then, the actuator 50 has an unlocked position (position shown in FIGS. 3 to 9) rotated about the rotation support shaft 51 and the locked shaft 53 slightly rearward from a position orthogonal to the insulator 20. It is possible to rotate between the lock position (the position shown in FIGS. 10 to 13) which is tilted forward from the lock position and becomes substantially horizontal. When the actuator 50 rotates to the lock position, the left and right lock holding surfaces 54 abut against the left and right support planes 25 with the pressing protrusion 55 positioned between the left and right side walls 22, and the left and right lock engaging portions 56. Are respectively engaged with the lock holding grooves 26 of the insulator 20, so that the actuator 50 is held in the lock position.

The cover member 70 that is a member extending in the left-right direction is obtained by injection-molding a heat-resistant synthetic resin material using a metal mold. The cover member 70 includes a base plate portion 71 extending in the left-right direction, a suction plate portion 72 extending in a direction substantially orthogonal to the base plate portion 71 from one edge in the short direction of the base plate portion 71, and a base plate portion 71 and a pair of side wall portions 73 that connect the side portions of the suction plate portion 72, a pair of leg portions 74 that extend from the end portions of the left and right side wall portions 73 in a direction substantially orthogonal to the suction plate portion 72, The outer shaft 75 and the inner shaft 76 projecting coaxially from the front end portion of the leg portion 74 to the left and right sides, and the suction plate portion 72 protruding from the connection edge portion of the suction plate portion 72 of the base plate portion 71 are parallel to the suction plate portion 72. Gripping protrusions (unlock holding portions) 77. As shown in FIGS. 8 and 13, etc., the outer shaft 75 has a non-circular cross section, and the outer surface of the outer shaft 75 has a pair of open position holding surfaces (open position holding means) 75a parallel to each other. A pair of closed position holding surfaces 75b that are respectively positioned between the two open position holding surfaces 75a and orthogonal to the open position holding surface 75a are formed. As shown in the drawing, the surface of the base plate portion 71 is constituted by two surfaces intersecting each other, and the portion on the suction plate portion 72 side is an inclined support surface 71 a inclined with respect to a plane orthogonal to the suction plate portion 72. ing. The surface (upper surface in FIGS. 1 and 2) of the suction plate portion 72 is a flat flat suction surface 78, and the surface of the gripping protrusion 77 is located on the same plane as the flat suction surface 78 and is a flat suction surface 78. It becomes the extended plane 79 which continues.
As shown in FIGS. 1 and 2, the cover member 70 is inserted into the leg receiving groove 34 and the shaft insertion groove 32 from the rear with the left and right leg portions 74 and the outer shaft 75 being substantially orthogonal to the insulator 20. In addition, the inner shaft 76 is attached to the insulator 20 by engaging with the inner shaft support groove 33. When the left and right inner shafts 76 are engaged with the inner shaft support groove 33, the front and rear walls of the inner shaft support groove 33 are positioned on both front and rear sides of the inner shaft 76, so that the outer shaft 75 (unless it is intentionally removed). The inner shaft 76 does not come out rearward from the shaft insertion groove 32 and the inner shaft support groove 33. The cover member 70 is centered on the left and right outer shafts 75 and the inner shaft 76, and is in an open position (position shown in FIGS. 3 to 10) substantially orthogonal to the insulator 20, and is tilted rearward from the open position to be substantially horizontal. And a closed position (positions shown in FIGS. 11 to 13). When the cover member 70 is rotated to the open position, the pair of open position holding surfaces 75a of the left and right outer shafts 75 are in surface contact with the upper and lower surfaces of the shaft insertion groove 32, thereby holding the cover member 70 in the open position (FIG. 8). In addition, the flat suction surface 78 and the extension plane 79 become substantially horizontal. On the other hand, when the cover member 70 is rotated to the closed position, the pair of closed position holding surfaces 75b of the left and right outer shafts 75 are in surface contact with the upper and lower surfaces of the shaft insertion groove 32, so that the cover member 70 is held in the closed position ( (See FIGS. 11 and 13).
As shown in FIGS. 3 to 9, when the cover member 70 is positioned in the open position when the actuator 50 is in the unlock position, the auxiliary suction surface 58 of the actuator 50 positioned in front of the cover member 70 is covered. The member 70 is in surface contact (supported) with the inclined support surface 71 a of the member 70. Further, since the unlock holding engagement groove 57 is engaged with the tip end portion of the gripping protrusion 77 from below, the actuator 50 is held in the unlock position by the cover member 70.

  In order to mount the connector 10 having the above configuration on the upper surface (circuit forming surface) of the circuit board CB (refer to the imaginary line in FIGS. 5 to 8, 12, and 13), the actuator 50 is positioned at the unlock position and the cover With the member 70 held in the open position (the state shown in FIGS. 3 to 9), the suction means 87 (see the phantom line in FIG. 5) located above the connector 10 is brought close to the connector 10, and the suction means 87 The flat suction surface 78 and the extended flat surface 79 which are in a substantially horizontal state are adsorbed. Since the flat suction surface 78 and a part of the extension plane 79 are both located immediately above the straight line connecting the left and right outer shafts 75 and the inner shaft 76, the flat suction surface 78 The pressing force received by the extension plane 79 from the suction means 87 can be received by the left and right outer shafts 75 and the inner shaft 76. Then, by moving the suction means 87, the tail portions 41 of the signal contacts 40 are placed on a solder paste applied to a circuit pattern (not shown) on the circuit board CB, and the tail portions 61 of the left and right fixing brackets 60 are placed on the circuit board CB. It is placed on the solder paste applied to the upper ground pattern (not shown). Then, after the suction means 87 that has lost the suction force is retracted above the connector 10, each solder paste is heated and melted in a reflow furnace, each tail portion 41 is soldered to the circuit pattern, and each tail portion 61 is Soldering to the ground pattern (at this time, the flat suction surface 78 and the extension plane 79 are substantially parallel to the circuit board CB).

  An FPC (Flexible Printed Circuit) 80 that is an object to be connected is a thin plate-like long object that can be elastically deformed. It is smaller than the vertical interval between the cam portion 52 and the contact projection 43 when the state is in the state. The FPC 80 has a laminated structure in which a plurality of thin film materials are bonded to each other, and a total of 28 circuit patterns (not shown) extending linearly along the extending direction of the FPC 80 are arranged in the left-right direction on the lower surface of the FPC 80. The lower surface of the portion excluding both ends of the circuit pattern is covered with an insulating cover layer. Further, a pair of locked portions 81 projecting outward is integrally provided on both left and right side portions of at least one end portion of the FPC 80 in the longitudinal direction.

When the end of the FPC 80 is inserted into the FPC insertion groove 21 from the front with the actuator 50 of the connector 10 mounted on the circuit board CB positioned at the unlock position (see FIGS. 6 and 9), the left and right sides of the FPC 80 Since the to-be-latched portions 81 are fitted into the corresponding retaining recesses 23 from above, the removal to the FPC 80 is restricted by the retaining recesses 23 (see FIG. 9). When the actuator 50 is rotated forward while releasing the engagement between the unlock holding engaging groove 57 and the gripping protrusion 77 in this state, each cam portion 52 of the actuator 50 presses the upper surface of the FPC 80 downward. When the actuator 50 rotates to the locked position, the pressing protrusion 55 of the actuator 50 comes into pressure contact with the upper surface of the FPC 80, so that the circuit pattern of the FPC 80 contacts the contact protrusion 43 while elastically deforming the elastic deformation portions 42 of the signal contacts 40 downward. (See FIGS. 10 to 12).
When the gripping protrusion 77 is gripped by hand and the cover member 70 is rotated backward to the closed position while releasing the engagement between the upper and lower surfaces of the shaft insertion groove 32 and the pair of open position holding surfaces 75a, FIG. As shown, the upper, rear, and side portions of each tail portion 41 are covered by the cover member 70, so that dust and dust are prevented from adhering to each tail portion 41.
The FPC 80 can be pulled out of the insulator 20 by releasing the engagement between the left and right lock engaging portions 56 and the lock holding groove 26 and then rotating the actuator 50 to the unlock position. Further, each signal can be obtained by grasping the gripping protrusion 77 by hand and rotating the cover member 70 forward to the open position while releasing the engagement between the upper and lower surfaces of the shaft insertion groove 32 and the pair of closed position holding surfaces 75b. The tail portion 41 of the contact 40 is exposed again.

As described above, the connector 10 of the present embodiment is provided with the gripping protrusion 77 on the cover member 70, and therefore comprises the flat suction surface 78 and the extension plane 79 on the upper surface of the cover member 70 when rotated to the open position. A substantially horizontal and large adsorption surface is formed. This suction surface (flat suction surface 78, extended flat surface 79) is larger than the suction surface of a conventional cover member that does not include the flat suction surface 78 (grip protrusion 77). Also, the suction member 87 can reliably adsorb the cover member 70.
10 to 13, when the actuator 50 is positioned at the lock position, the auxiliary suction surface 58 becomes substantially horizontal. Therefore, after the flat suction surface 78 and the extension plane 79 are sucked by the suction means 87, they are further separated. If the auxiliary suction surface 58 is sucked by the suction means, the total area of the suction surfaces formed on the connector 10 is further increased. Therefore, the suction of the connector 10 by the suction means becomes more reliable.
Further, the cover member 70 is securely held in the open position by the open position holding surface 75a of the outer shaft 75 and the upper and lower surfaces of the shaft insertion groove 32, and then the actuator 50 (unlock holding engagement groove 57) rotated to the unlock position. ) Is held in the unlocked position by engaging the gripping protrusion 77, so that the actuator 50 can be securely held in the unlocked position and the cover member 70 can be securely held in the open position.

In addition, the engagement between the actuator 50 and the cover member 70 can more effectively prevent the cover member 70 from inadvertently rattling or falling due to the pressing force of the suction means 87 when the connector 10 is sucked. For this reason, the suction surface (flat suction surface 78, extended flat surface 79) can be maintained in a horizontal state and reliable suction can be realized.
In addition, although the cover member 70 positioned at the open position is located slightly rearward in the entire connector 10, the gripping protrusion 77 is provided on the cover member 70, so that the suction position is determined (the gripping protrusion 77. Since the position of the center of gravity of the connector 10 is close to that of the connector 10 as compared with the case where the connector 10 is not provided, the connector 10 can be prevented from being tilted during suction and conveyance by the suction means 87, and thus stable mounting is possible.
Further, when the connector 10 (and the cover member 70) is small, the opening / closing operability of the cover member 70 is lowered, but the operability is improved by providing the gripping protrusions 77. In particular, when the connector 10 is low in height, it is difficult to open the cover member. However, the connector 10 according to the present embodiment can grip (or hook) the gripping protrusion 77 with a hand, and thus the operation is extremely easy. Become.
Furthermore, in this embodiment, when the cover member 70 is located at the closed position, the gripping protrusion 77 does not protrude from the upper surface of the insulator 20 (see FIG. 13), so that the overall height of the connector 10 can be reduced. However, when the operability and adsorption property of the cover member 70 are further emphasized, by increasing the protruding amount of the gripping projection piece 77, the gripping projection piece 77 is attached to the insulator 20 when the cover member 70 is located at the closed position. You may make it protrude from an upper surface.

Further, when the cover member 70 is located at the open position, it includes an inclined support surface 71a that is inclined backward with respect to a vertical surface (a plane perpendicular to the insertion / removal direction of the FPC 80). Since the auxiliary suction surface 58 of the actuator 50 that is positioned is supported, the relative positional accuracy (the unlock position and the open position) between the actuator 50 and the cover member 70 can be improved. Further, since the actuator 50 in the unlock position does not rotate in the anti-lock direction inadvertently, the actuator 50 can be prevented from being damaged or dropped off.
Further, by forming the inclined support surface 71a on the cover member 70, the opening angle from the lock position to the unlock position side of the actuator 50 is made larger than 90 ° without increasing the longitudinal dimension of the connector 10. The insertion / removal property of the FPC 80 with respect to the insulator 20 is good.

As mentioned above, although this invention was demonstrated based on the said embodiment, this invention is not limited to the said embodiment, It can implement, giving various deformation | transformation.
For example, the modification shown in FIGS. 14 and 15 can be implemented.
This connector 10 ′ has the same configuration as the connector 10 except that it includes a ground contact 90.
The ground contact 90 is formed in the same manner as the signal contact 40, and has a tail portion 91 formed so as to form a substantially L shape at the front end portion, and an elastic extending obliquely upward and rearward from the upper portion of the tail portion 91. A deformation portion 92 and a contact protrusion 93 protruding from the upper surface near the tip of the elastic deformation portion 92 are provided. Each ground contact 90 is press-fitted into the contact insertion groove 35 of the insulator 20 from the front. As shown in FIG. 15, when each ground contact 90 is press-fitted into the contact insertion groove 35, the locking protrusions protruding in the vicinity of the base end (horizontal part) of the side surface of the elastic deformation portion 92 correspond to the corresponding contact insertion groove 35. Since the tail portion 91 bites into the side surface and engages with the front edge portion of the contact insertion groove 35 from the front, the ground contact 90 cannot move back and forth with respect to the insulator 20. The lower surface of each tail part 91 is located on the same plane as the lower surfaces of the tail part 41 and the tail part 61, and the latter half part of the elastic deformation part 92 can be elastically deformed in the vertical direction.
The connector 10 ′ is mounted on the circuit board CB in the same manner as the connector 10 by using the suction means 87 (and another suction means). At this time, the tail portion 91 of each ground contact 90 is soldered to the ground pattern on the circuit board CB.
The FPC 80 ′ used in this modification also has a laminated structure in which a plurality of thin film materials are bonded to each other, and the thickness thereof is such that when the actuator 50 is located at the unlock position (the signal contact 40 and the ground contact 90 are in a free state). It is smaller than the vertical interval between the cam portion 52 and the contact projection 43 and the vertical interval between the cam portion 52 and the contact projection 93. A total of 28 circuit patterns 82 extending linearly along the extending direction of the FPC 80 ′ are formed in the FPC 80 ′ in the left-right direction, and the lower surface of the portion excluding both ends of the circuit pattern 82 is covered by the insulating cover layer 83. Covering. On the lower surface of the insulating cover layer 83, a total of 28 ground patterns 84 that are parallel to the circuit pattern 82 and shorter than the circuit pattern 82 are formed side by side in the left-right direction, and the lower surface of the portion excluding both ends of the ground pattern 84 Is covered with an insulating cover layer 85.
When the end of the FPC 80 ′ is inserted into the FPC insertion groove 21 from the front with the actuator 50 positioned at the unlock position, the end of the FPC 80 ′ is brought into contact with the contact protrusion 43 and the contact protrusion in the FPC insertion groove 21. Since the actuator 50 is rotated to the locked position in this state, the upper surface of the FPC 80 ′ is pressed downward by the cam portions 52 and the pressing protrusions 55 of the actuator 50. The contact protrusion 43 of the contact 40 contacts the end of the circuit pattern 82, and the contact protrusion 93 of each ground contact 90 contacts the end of the ground pattern 84 (see FIG. 15).
The connector 10 ′ of this modification can also exhibit the same function and effect as the connector 10.

Further, the connector 10 may be mounted on the circuit board CB by sucking the cover member 70 with the suction means 87 in a state where the actuator 50 is located at the lock position.
Further, according to the number of poles (the number of contacts) of the connector 10 and the specifications of the suction means 87, a single gripping protrusion 77 and an extension plane 79 are formed over the entire region in the left-right direction of the cover member 70, or a plurality of The gripping protrusion 77 and the extension plane 79 may be formed on the cover member 70.
Further, the insulator and the contact group are connected in a manner orthogonal to the circuit board, and the FPC is inserted into and removed from the insulator through the FPC insertion / removal opening formed at the end of the insulator opposite to the circuit board (contact group). The cover member may be rotatably connected to an insulator of a connector that is in contact with and separated from the connector. In this case, the end portion of the contact group opposite to the FPC insertion / removal opening protrudes outside the insulator and constitutes a tail portion that is connected to the circuit board. The cover member is rotatable between an open position that exposes the tail portion substantially orthogonal to the circuit board and a closed position that falls to the tail portion side and covers the tail portion. A suction surface (flat suction surface, extended plane) formed on a flat surface formed on the projecting piece is substantially parallel to the circuit board on the side opposite to the circuit board when positioned at the open position.
Further, the actuator 50 may be omitted from the connectors 10, 10 ′.
Further, the thin plate-like connection object may be a cable other than the FPC, for example, a flexible flat cable (FFC).
