In the closed position, the latching arm portion 24a closes the outside of the side slit 13a in the upper side space portion 17a, so that the insertion into the side slit 13a of the tab portion 131 of the flat cable 101 becomes impossible. The flat cable 101 cannot be connected to the cable connector 1. On the other hand, in the open position, the latching arm portion 24a opens the outside of the side slit 13a in the upper side space portion 17a, so that the tabular cable 101 can be inserted into the side slit 13a of the ear portion 131. As a result, the flat cable 101 can be connected to the cable connection connector 1. The inclination angle between the base portion 23 of the cover member 21 and the first portion 14a of the housing 11 in the open position is regulated by the leg portion 22 coming into contact with the stopper portion 12a.

  Next, an assembly process of the cable connecting connector 1 will be described.

  FIG. 4 is a diagram for explaining an assembly process of the connector in the embodiment of the present invention. In the figure, (a) is a diagram showing a process of attaching the cover member to the housing, and (b) is a diagram showing a process of attaching the auxiliary metal fitting to the housing.

  First, the terminal 51 is loaded in the housing 11. In this case, as shown in FIG. 3, the terminal 51 is relatively moved upward from the lower end 11 b side of the housing 11, and the terminal 51 is inserted into the terminal holding recess 16. The terminals 51 arranged so as to be aligned in the width direction of the housing 11 are so positioned that the tail portions 52 are alternately positioned on the first portion 14a and second portion 14b sides for each adjacent terminal 51. And inserted into the terminal holding recess 16. Thereby, the tail part 52 is arrange | positioned in zigzag form in planar view.

  Subsequently, the cover member 21 is attached to the housing 11. In this case, as shown in FIG. 4A, the cover member 21 is arranged such that the base portion 23 is parallel to the first portion 14 a of the housing 11 and the latching arm portion 24 a and the leg portion 22 face the direction of the housing 11. To control the attitude. Then, the cover member 21 is relatively moved from the first portion 14a side of the housing 11 toward the second portion 14b in the direction of the second portion 14b, so that the pair of latching arm portions 24a are moved upward. The pair of leg portions 22 is inserted into the lower side space portion 17b.

  Subsequently, the auxiliary metal fitting 81 is attached to the housing 11. In this case, as shown in FIG. 4B, the auxiliary metal fitting 81 so that the tail part 82 and the base part 83 are parallel to the lower end 11 b and the side part 11 c of the housing 11 and the arm part 84 faces the direction of the housing 11. To control the attitude. Then, the auxiliary metal fitting 81 is relatively moved upward from the lower end 11 b side of the housing 11, and the arm portion 84 is inserted into the metal fitting receiving recess formed in the fixing portion 17. At this time, the shaft portion 26 of the cover member 21 relatively enters the shaft passage portion 85, relatively moves the shaft passage portion 85 downward, and finally reaches the inside of the bearing portion 86. . Thereby, the assembly of the connector 1 for cable connection is completed.

  The shaft passing portion 85 has a wide portion 85a near the upper end and a narrow portion 85b near the lower end, that is, a portion adjacent to the bearing portion 86. Preferably, the wide portion 85 a is formed wider than the shaft portion 26 of the cover member 21, and the narrow portion 85 b is formed narrower than the shaft portion 26 of the cover member 21. Therefore, the shaft part 26 of the cover member 21 can be easily inserted into the wide part 85a. Further, since the narrow portion 85 b adjacent to the bearing portion 86 is narrower than the shaft portion 26 of the cover member 21, the shaft portion 26 of the cover member 21 housed in the bearing portion 86 is difficult to be extracted from the bearing portion 86. . In the assembly of the cable connecting connector 1, when the shaft portion 26 that moves relatively downward passes through the narrow portion 85b, the arm portion 84 and the like are elastically deformed, and the narrow portion 85b. Is extended by the shaft portion 26.

  Next, the operation of connecting the flat cable 101 to the cable connecting connector 1 will be described.

  FIG. 5 is a view showing a state immediately before the cable is inserted into the connector in the embodiment of the present invention, FIG. 6 is a view showing a state in which the cable is inserted into the connector in the embodiment of the present invention, and FIG. The figure which shows the state which closed the cover member after inserting the cable in the connector in embodiment, FIG. 8 is a sectional side view of the connector in embodiment of this invention, and is a figure which shows the principal part side cross section of FIG. is there. 8A is a side sectional view passing through the terminal, and FIG. 8B is a side sectional view passing through the leg portion and the latch arm portion of the cover member.

  In the present embodiment, the flat cable 101 as a cable is, for example, a flexible circuit board, a flexible flat cable, or the like, but any type of flat cable having a conductive wire 151 may be used. Good. And the flat cable 101 is equipped with the elongate strip | belt-shaped shape, as FIG. 5 shows. In the figure, the flat cable 101 is drawn only from the tip 101a to a predetermined distance, and the drawing of other parts is omitted. In addition, the flat cable 101 is bent approximately 90 degrees in the middle thereof, but is not necessarily bent, and may be in a linear state, for example.

  The flat cable 101 includes a substrate portion (not shown) that is an insulating thin plate member, and a plurality of conductive wires 151 disposed on one or both surfaces of the substrate portion. The conductive wire 151 is a foil-like linear body made of a conductive metal such as copper, and is arranged in parallel at a predetermined pitch, for example, about 0.2 [mm]. The number and pitch of the conductive wires 151 can be appropriately changed as necessary. The upper side of the conductive wire 151 is covered with an insulating layer (not shown). Note that the insulating layer is removed and the upper surface of the conductive wire 151 is exposed at the tip portion that is a portion extending from the tip 101a of the flat cable 101 to a predetermined length.

  Further, ear portions 131 projecting outward in the width direction are formed in the vicinity of the tip 101a of the flat cable 101, that is, on both side edges of the tip portion. A conductive layer made of a conductive metal is formed on at least a part of the surface of the ear portion 131, that is, on the surface including at least the rear side surface 131a. The conductive layer is electrically connected to a ground line or a power supply line (not shown) included in the flat cable 101.

  Here, the connector 1 for cable connection shall be mounted on the surface of the board | substrate which is not shown in figure. Specifically, the tail portion 52 of the terminal 51 is connected to a connection pad formed on the surface of the substrate facing the lower end 11b by soldering or the like, and the tail portion 82 of the auxiliary metal fitting 81 is connected to the surface of the substrate. It is assumed that it is mounted upright on the substrate by being connected to the fixing pads formed on it by soldering. The connection pad is electrically connected to a conductive trace of the substrate, and the fixing pad is electrically connected to a ground line or a power supply line of the substrate.

  When connecting the flat cable 101 to the cable connecting connector 1, first, as shown in FIG. 5, the posture of the cover member 21 is set to the open position. Then, the attitude of the flat cable 101 is controlled so that the tip 101a faces the upper end 11a of the housing 11 and is parallel to the insertion recess 13 opened to the upper end 11a. Subsequently, the distal end portion of the flat cable 101 is relatively moved toward the upper end 11a of the housing 11, and the distal end portion is inserted into the insertion recess 13 that opens to the upper end 11a.

  When the distal end portion of the flat cable 101 is relatively lowered in the insertion recess 13, the ear portion 131 enters the side slit 13 a of the housing 11, and the outer end 131 b of the ear portion 131 is the upper side space portion. It will be in the state protruded to 17a. Further, the exposed conductive wire 151 abuts on the contact portion 54 a formed near the upper end of the arm portion 54 of the terminal 51 and slides. In the present embodiment, the distance between the contact portions 54 a facing each other is set to a dimension equal to or less than the thickness of the flat cable 101. Therefore, the distal end portion of the flat cable 101 inserted into the insertion recess 13 is inserted into the insertion recess 13 while receiving contact pressure from the contact portion 54a. That is, the cable connecting connector 1 in the present embodiment has a non-ZIF (Zero Insertion Force) structure.

  Subsequently, when the distal end 101a of the flat cable 101 reaches the back of the insertion recess 13 and the insertion of the flat cable 101 is completed, the state shown in FIG. 6 is obtained. In this case, since the ear portion 131 has also reached the back of the side slit 13a and the upper side space portion 17a, that is, the lower side, the rear side surface 131a of the ear portion 131 is also sufficiently below the upper end 11a of the housing 11. Has reached a position separated from

  Subsequently, as illustrated in FIG. 7, the posture of the cover member 21 is set to the closed position. In this case, since the ear part 131 in the side slit 13a and the upper side space part 17a is located sufficiently below, above the rear side surface 131a of the ear part 131 in the upper side space part 17a, There is a space in which the latch arm 24a can be inserted. Therefore, the posture of the cover member 21 can be changed from the open position as shown in FIG. 6 to the closed position as shown in FIG.

  Thus, when the posture of the cover member 21 is in the closed position, as shown in FIG. 8A, the distal end portion of the flat cable 101 is inserted into the cable insertion portion 55 of the terminal 51 and faces each other. The contact portion 54a is sandwiched between the conductive wires 151 exposed on the surface of the flat cable 101 and the contact portion 54a. Therefore, the conductive state between each conductive wire 151 of the flat cable 101 and the corresponding terminal 51 is reliably maintained.

  Further, as shown in FIG. 8B, in the upper side space portion 17a, the latching arm portion 24a is located above the ear portion 131 and restricts the upward displacement of the ear portion 131. The flat cable 101 is reliably prevented from being pulled out from the insertion recess 13. In addition, when the force which displaces the flat cable 101 upward is applied from the outside, the said force is transmitted via the ear | edge part 131 and the latching arm part 24a, and the whole cover member 21 is upwards with respect to the housing 11. Although it will be displaced, when the upper end of the leg part 22 inserted in the lower side space part 17b contact | abuts the lower end of the connection part 17c of the fixing | fixed part 17, the upward displacement of the cover member 21 is controlled. Is done. Therefore, even in such a case, the flat cable 101 is reliably prevented from being pulled out from the insertion recess 13.

  Furthermore, since the latching arm portion 24a contacts the rear side surface 131a of the ear portion 131, the ground line or power supply line of the cable connecting connector 1 is connected to the ground of the board via the conductive layer of the cover member 21 and the rear side surface 131a. Conductive with line or power line. Therefore, generation of static electricity is surely prevented.

  Note that the operation of releasing the connection between the cable connecting connector 1 and the flat cable 101 is the reverse of the operation of connecting the cable connecting connector 1 and the flat cable 101, and thus the description thereof is omitted.

  As described above, in the present embodiment, the cable connecting connector 1 includes the housing 11 having the insertion recess 13 into which the distal end portion of the flat cable 101 including the ear portions 131 protruding from both side edges is inserted, and the housing 11. The terminal 51 that is loaded and electrically connected to the conductive wire 151 of the flat cable 101 and the auxiliary metal fitting 81 attached to the housing 11 are connected to connect the flat cable 101. The cover member 21 further includes a cover member 21 that is rotatably attached to the auxiliary metal fitting 81 and changes its posture between an open position and a closed position. The cover member 21 includes a latch arm part 24a, and the latch arm part 24a includes: When the cover member 21 is in the open position, the end portion of the flat cable 101 can be inserted into the insertion recess 13, and when the cover member 21 is in the closed position, the ear 131 is hooked to Thus, the cable connection connector 1 is mounted on the substrate in such a posture that the insertion direction of the tip portion of the flat cable 101 is perpendicular to the substrate.

  Thereby, the flat cable 101 can be connected easily and reliably without occupying a large area on the substrate, and the connected flat cable 101 is not detached, so that reliability is improved. Can be improved.

  The cable connector 1 according to the present embodiment has a width (distance between the ends of the left and right auxiliary fittings 81) of about 5 [mm] and a height (from the board surface mounted on the board to the housing), for example. 11 is about 2.3 [mm], and the thickness (the distance from the base 23 to the second portion 14b when the cover member 21 is closed) is about 1.5 [mm]. . Therefore, as shown in FIGS. 1 and 2, etc., the cable connector 1 is mounted on the board in such a posture that the insertion direction of the tip portion of the flat cable 101 is perpendicular to the board. The area occupied by the board is substantially equal to the width × thickness of the cable connecting connector 1 and is a relatively small value, whereas the insertion direction of the tip portion of the flat cable 101 is temporarily with respect to the board. Imagine the state of being mounted on the board in a parallel orientation, it can be seen that the area occupied by the board will be approximately equal to the width x height of the cable connector 1 and will be a relatively large value. . In addition, when the flat cable 101 is inserted into the insertion recess 13, a certain amount of work space is required on the side where the insertion recess 13 is open, so that a larger area on the substrate will be required. I understand that.

  The housing 11 includes a main body portion 12 including the insertion recess 13 and a fixing portion 17 that protrudes outward from the side portion 11c of the main body portion 12 and to which the auxiliary metal fitting 81 is attached. When the cover member 21 is in the open position, the latching arm portion 24a is located outside the upper space portion 17a when the side slit 13a is formed to communicate with the upper space portion 17a between the fixing portion 17 and the side portion 11c. The tab 131 of the flat cable 101 can pass through the side slit 13a with its outer end protruding into the upper space 17a, and when the cover member 21 is in the closed position, The stop arm portion 24a is inserted into the upper space portion 17a, and hooks the portion protruding into the upper space portion 17a of the ear portion 131 of the flat cable 101 in which the distal end portion is inserted into the insertion recess 13.Therefore, by setting the cover member 21 to the closed position, it is possible to reliably prevent the distal end portion of the flat cable 101 from being pulled out from the insertion recess 13.

  Further, the fixing portion 17 is connected to the side portion 11c through the connecting portion 17c, and the side space portion is composed of an upper side space portion 17a and a lower side space portion 17b on the upper side and the lower side of the connecting portion 17c, and a cover. The member 21 is a leg portion 22 inserted into the lower side space portion 17b, and a shaft portion 26 connected to the tip of the leg portion 22, and is inserted into a bearing portion 86 formed in the auxiliary metal part 81 to rotate. When the cover member 21 is in the closed position, the latching arm portion 24a is inserted into the upper space portion 17a. Therefore, even if a force in the direction of pulling out the distal end portion of the flat cable 101 from the insertion recess 13, that is, an upward force is applied from the outside, such a force is applied via the cover member 21 to the auxiliary metal fitting. Since it is received by 81, the cover member 21 is not displaced upward, and it is possible to reliably prevent the distal end portion of the flat cable 101 from being pulled out from the insertion recess 13.

  Furthermore, the main body 12 of the housing 11 includes an upper end 11a where the insertion recess 13 and the side slit 13a are opened, and a lower end 11b that is located on the opposite side of the upper end 11a and faces the substrate. A metal fitting recess that opens to the lower end 11b side is formed, and the auxiliary metal fitting 81 includes a base portion 83, a tail portion 82 that is bent from the lower end of the base portion 83 and extends sideward, and an upper side from the upper end of the base portion 83. A pair of arm portions 84 extending toward each other, a groove-shaped shaft passage portion 85 formed between the arm portions 84, and a bearing portion 86 formed continuously at the lower end of the shaft passage portion 85. After the leg part 22 of the cover member 21 is inserted into the lower side space part 17b of the housing 11, the auxiliary metal fitting 81 is relatively moved from the lower end 11b side so as to be inserted into the metal fitting receiving recess. Of the cover member 21 when Part 26 is inserted into the bearing portion 86 through the shaft passage portion 85. Therefore, even if an upward force is applied from the outside, such a force is also received by the housing 11 via the cover member 21, so that the cover member 21 is not displaced upward. Further, it is possible to more reliably prevent the distal end portion of the flat cable 101 from being pulled out from the insertion recess 13. Further, the cable connecting connector 1 can be assembled by easily coupling the housing 11, the cover member 21, and the auxiliary metal fitting 81.

  Further, the ear 131 of the flat cable 101 includes a rear side surface 131a on which a conductive layer is formed. The cover member 21 is made of metal. When the cover member 21 is in the closed position, the hooking arm 24a has the ear 131. The shaft portion 26 contacts at least a part of the peripheral edge of the bearing portion 86. Therefore, since the conductive layer of the flat cable 101 is electrically connected to the auxiliary metal fitting 81 connected to the substrate through the cover member 21, the generation of static electricity can be effectively prevented.

  In addition, this invention is not limited to the said embodiment, It can change variously based on the meaning of this invention, and does not exclude them from the scope of the present invention.

  The present invention can be applied to a connector.
