Description

  The present invention relates to a flat cable connector to which a flat cable such as a flexible flat cable (FFC) and a flexible circuit board (FPC) is connected.

As a conventional flat cable connector of this type, for example, the one shown in FIG. 10 is known (see Patent Document 1). FIG. 10 is a cross-sectional view of an example of a conventional flat cable connector.
A flat cable connector 100 shown in FIG. 10 includes an insulating housing 110 having a flat cable receiving opening 111 into which a flat cable 140 can be inserted and removed. A plurality of contacts 120 are attached to the housing 110 along the width direction thereof. Each contact 120 has an upper contact beam 124 that contacts the upper surface of the flat cable 140 inserted into the flat cable receiving opening 111 and a lower contact beam 123 that contacts the lower surface of the flat cable 140. Contact protrusions 124 a and 123 a are formed at the tips of the upper contact beam 124 and the lower contact beam 123, respectively. The contact 120 has a base 121 that extends from the front side (left side in FIG. 10, the front side in the flat cable insertion direction) to the rear side (right side in FIG. 10, the back side in the flat cable insertion direction). The base 121 is press-fitted and fixed to the housing 110 from the rear of the housing 110. The lower contact beam 123 is provided at the upper end of a fulcrum part 122 that extends upward from a substantially central part in the front-rear direction of the base part 121. The lower contact beam 123 is elongated in the front-rear direction with the fulcrum part 122 interposed therebetween. The upper contact arm 124 rises from a portion on the rear side of the fulcrum portion 122 of the lower contact beam 123 and extends forward so as to face the lower contact beam 123.

  The flat cable connector 100 includes an actuator 130. When the flat cable 140 is inserted into the flat cable receiving opening 111, the actuator 130 applies contact pressure to the flat cable 140 by the upper contact beam 124 and the lower contact beam 123 by a turning operation. Specifically, the actuator 130 can be rotated relative to the housing 110 from the rotation operation start position to the rear side, that is, by rotating in the arrow A direction in FIG. It is supported by. FIG. 10 shows a state where the actuator 130 is at the rotation operation end position.

  Each contact 120 is provided with an operating portion 125 that is driven by a rotation operation of the actuator 130. The operating unit 125 is provided at the rear end of the lower contact beam 123. The actuator 125 is pushed upward by the drive unit 131 of the actuator 130 when the actuator 130 is rotated rearward, and the upper contact beam 124 is displaced downward. Thereby, the contact pressure with respect to the flat cable 140 by the upper contact beam 124 and the lower contact beam 123 is applied.

As another example of a conventional flat cable, for example, the one shown in FIG. 11 is also known (see Patent Document 2). FIG. 11 is a cross-sectional view of another example of a conventional flat cable connector.
A flat cable connector 200 shown in FIG. 11 includes an insulating housing 210 having a flat cable receiving opening 211 into which the flat cable 250 can be inserted and removed. A plurality of contacts 220 are attached to the housing 210 along the width direction thereof. Each contact 220 includes a base 221 that is press-fitted from the rear end of the housing 210 (the rear end in the flat cable insertion direction, the right end in FIG. 11). A connecting portion 223 extends forward from the upper end of the front edge of the base portion 221, and a rotation support portion 222 is provided at the front end of the connecting portion 223. Further, a lower contact arm 224 extends from a substantially central portion in the front-rear direction of the lower end edge of the connecting portion 223. The lower contact arm 224 extends downward from the connecting portion 223 and further forwards. The lower contact arm 224 contacts the lower surface of the flat cable 250 inserted in the flat cable receiving opening 211.

The flat cable connector 200 includes an actuator 230. When the flat cable 250 is inserted into the flat cable receiving opening 211, the actuator 230 applies contact pressure to the flat cable 250 by the lower contact beam 224 by a turning operation. More specifically, the actuator 230 rotates with respect to the rotation support portion 222 from the rotation operation start position to the front side, that is, by rotating in the arrow B direction in FIG. It is supported movably. FIG. 11 shows a state where the actuator 230 is at the rotation operation end position. When the actuator 230 rotates to the front side from the rotation operation start position, the pressing portion 231 provided on the actuator 230 presses the upper surface of the flat cable 250. Thereby, the contact pressure with respect to the flat cable 250 by the lower contact beam 224 is applied.
Further, a pair of restraining blades 240 (only one is shown) are provided at both front ends of the housing 210 in the width direction. These restraining blades 240 are positioned so as to be close to or in contact with the upper surface of the flat cable 250 and restrict the upward movement of the flat cable 250.

However, the flat cable connector 100 shown in FIG. 10 and the flat cable connector 200 shown in FIG. 11 have the following problems.
That is, in the case of the flat cable connector 100 shown in FIG. 10, the actuator 125 is locked by the drive part 131 of the actuator 130 when the actuator 130 is in the rotation operation end position. For this reason, when the flat cable 140 that has been inserted is wound upward as indicated by the arrow X in FIG. 10, the lower contact beam 123 cannot follow the flat cable 140, which may cause contact failure.

  Further, in the case of the flat cable connector 200 shown in FIG. 11, since the restraining blade 240 is provided, the actuator 230 rotates and the flat cable 250 is disconnected when the flat cable 250 is rolled upward. Absent. However, as shown in FIG. 11, when a load is applied below the flat cable 250 bent upward as indicated by the arrow Y, there is no member that receives the load applied to the flat cable 250. For this reason, the load which moves to the downward direction acts also on the vicinity of the part which the lower side contact beam 224 of the flat cable 250 is contacting. Here, in the flat cable connector 200 shown in FIG. 11, when it is assumed that the upper contact beam exists like the flat cable connector 100 shown in FIG. 10, the flat cable 250 tends to move away from the upper contact beam. For this reason, the contact pressure with respect to the flat cable 250 by an upper side contact beam falls, and there exists a possibility that a contact failure may arise.

  Accordingly, the present invention has been made in view of these problems, and an object of the present invention is to provide a flat cable connector having an upper contact beam and a lower contact beam whose contacts contact the upper and lower surfaces of the flat cable. In the case where the lower contact beam can follow the flat cable when it is beaten upward, it avoids poor contact of the lower contact beam, and also when a downward load is applied to the flat cable bent upward An object of the present invention is to provide a flat cable connector capable of avoiding contact failure of an upper contact beam.

  To achieve the above object, a flat cable connector according to claim 1 of the present invention is an insulating housing having a flat cable receiving opening through which a flat cable can be inserted and removed, and a contact attached to the housing. A contact having an upper contact beam facing the upper surface of the flat cable inserted into the flat cable receiving opening and a lower contact beam contacting the lower surface of the flat cable; A flat cable connector comprising an actuator for applying contact pressure to the flat cable by the upper contact beam and the lower contact beam by a rotation operation when inserted into the cable receiving opening, Extending from the lower contact beam; An actuator that is driven by a pivoting operation of the actuator to displace the lower contact beam upward and applies contact pressure to the flat cable by the upper contact beam and the lower contact beam; When the flat cable inserted into the flat cable receiving opening is bent upward on the front side of the flat cable insertion direction, the bending position of the flat cable is isolated from the upper contact beam to the front side of the flat cable insertion direction. A flat cable bending position correcting section, and a load is applied downward to the flat cable bent upward, below the flat cable bending position correcting section and on the near side of the flat cable insertion direction of the lower contact beam. Load receiving part that receives the flat cable when It is characterized in that.

Moreover, the flat cable connector which concerns on Claim 2 among this invention is a flat cable connector of Claim 1, The said flat cable bending position correction | amendment part is from a pair of solder peg provided in the width direction both ends of the said housing. It is characterized by extending.
Furthermore, a flat cable connector according to a third aspect of the present invention is the flat cable connector according to the first or second aspect, wherein the load receiving portion is a part of the housing.

  In addition, a flat cable connector according to a fourth aspect of the present invention is the flat cable connector according to any one of the first to third aspects, wherein the actuator is a rotation operation start position with respect to the housing. It is characterized by being supported so as to be able to turn to reach the turning operation end position by turning to the back side in the flat cable insertion direction.

  According to the flat cable connector according to the present invention, the contact extends from the lower contact beam and is driven by the rotation operation of the actuator, and the lower contact beam is displaced upward to be flat by the upper contact beam and the lower contact beam. An operating part for applying contact pressure to the cable was provided. As a result, when the flat cable is twisted upward, the lower surface of the flat cable tends to be separated from the lower contact beam, but the lower contact beam is displaced upward by the actuator and the operating part. The side contact beam can follow the movement of the flat cable. Therefore, when the flat cable is wound upward, the lower contact beam can follow the flat cable so that the contact failure of the lower contact beam can be avoided.

  Also, when the flat cable inserted into the flat cable receiving opening is bent upward on the front side of the upper contact beam in the flat cable insertion direction, the bending position of the flat cable is moved from the upper contact beam to the front side of the flat cable insertion direction. A flat cable bending position correction part for isolation was provided. As a result, when a load is applied downward with respect to the flat cable bent upward, the position of the flat cable to which the load is applied is separated from the upper contact beam, and the load applied to the flat cable is changed to the upper contact beam and the lower side. Direct contact between the contact beam and the flat cable can be avoided. Thereby, it can prevent that the upper surface of a flat cable moves below and leaves | separates from an upper side contact arm, and the contact failure of an upper side contact beam can be avoided.

  Furthermore, a load receiving portion that receives the flat cable when a load is applied downward to the flat cable bent upward and below the flat cable bending position correction portion and in front of the flat cable insertion direction of the lower contact beam. Equipped with. Thereby, when a load is applied downward to the flat cable bent upward, the load is received by the load receiving portion of the flat cable. For this reason, it can prevent that the upper surface of a flat cable moves below and leaves | separates from an upper side contact arm, and can avoid the contact failure of an upper side contact beam.

A flat cable connector 1 shown in FIG. 1 includes a housing 10, a plurality of first contacts 20 and second contacts 30 attached to the housing 10, an actuator 40, and a pair of left solder pegs 50 and right solder pegs 60. I have.
Here, the housing 10 is formed in a substantially rectangular shape extending in the width direction (left-right direction in FIG. 1) and the front-back direction (up-down direction in FIG. 2), and is integrally formed by molding an insulating synthetic resin. . The housing 10 is provided with a flat cable receiving opening 11 into which a flat cable 70 (see FIG. 9) can be inserted and removed. The flat cable receiving opening 11 extends rearward from the front end surface of the housing 10 (the lower end surface in FIG. 2 and the left end surface in FIGS. 4 and 5) along the width direction of the housing 10. In this embodiment, the flat cable 70 is configured by a flexible circuit board (FPC). The flat cable 70 is inserted into the flat cable receiving opening 11 along the flat cable insertion direction (front-rear direction), and is pulled out along the opposite direction.

The plurality of first contacts 20 and second contacts 30 are alternately attached in a line along the width direction of the housing 10.
As shown in FIG. 4, each first contact 20 includes a base portion 21, a lower contact beam 22, an upper contact beam 23, and an operating portion 24, and is formed by punching a metal plate. The base 21 is formed in a substantially rectangular flat plate shape, and is press-fitted and fixed to the housing 10 from the rear of the housing 10. At the lower end portion of the base portion 21, a substrate connecting portion 21a connected to a circuit board (not shown) is provided. The lower contact beam 22 extends forward from the lower end portion of the front end edge of the base portion 21 through the narrow portion 21 b and is positioned below the flat cable receiving opening 11. The upper contact beam 23 extends forward from the vicinity of the upper end portion of the front end edge of the base portion 21 and is positioned above the flat cable receiving opening 11. And the upper side contact beam 23 and the lower side contact beam 22 are facing up and down. Further, at the front end of the lower contact beam 22, a contact protrusion 22a that contacts the lower surface of the flat cable 70 (see FIG. 9A) inserted into the flat cable receiving opening 11 is formed to protrude upward. Yes. Further, a contact protrusion 23 a that contacts the upper surface of the flat cable 70 inserted into the flat cable receiving opening 11 is formed at the front end of the upper contact beam 23 so as to protrude downward. Further, the actuating portion 24 once rises from the rear portion of the lower contact beam 22 and extends further forward. The actuating portion 24 is driven by a rotation operation of the actuator 40 after the flat cable 70 is inserted into the flat cable receiving opening 11, and has a function of displacing the lower contact beam 22 upward. Thereby, the contact pressure with respect to the flat cable 70 by the upper contact beam 23 and the lower contact beam 22 is applied.

  As shown in FIG. 5, each second contact 30 includes a base 31, a lower contact beam 32, an upper contact beam 33, and a front extension 34, and is formed by punching a metal plate. . The base 31 is formed in a substantially rectangular flat plate shape, and is press-fitted and fixed to the housing 10 from the front of the housing 10. The lower contact beam 32 rises from the front end of the connecting portion 31 a extending forward from the lower end portion of the front end edge of the base portion 31 and extends further rearward and is positioned below the flat cable receiving opening 11. A board connecting part 31b connected to a circuit board (not shown) is provided at the lower end of the front end of the connecting part 31a. The upper contact beam 33 rises from the vicinity of the rear end of the connecting portion 31a and extends further forward and is positioned above the flat cable receiving opening 11. Further, the front extension 34 extends forward from the upper end of the front edge of the base 31. Further, a contact protrusion 32 a that contacts the lower surface of the flat cable 70 inserted into the flat cable receiving opening 11 is formed at the rear end of the lower contact beam 32 so as to protrude upward. Further, a contact protrusion 33 a that contacts the upper surface of the flat cable 70 inserted into the flat cable receiving opening 11 is formed at the front end of the upper contact beam 33 so as to protrude downward. After the flat cable 70 is inserted into the flat cable receiving opening 11, the drive unit 49 presses the front end of the upper contact beam 33 from above by the turning operation of the actuator 40, and the upper contact beam 33 is displaced downward. Let Thereby, the contact pressure with respect to the flat cable 70 by the upper contact beam 33 and the lower contact beam 32 is applied.

  Further, when the flat cable 70 is inserted into the flat cable receiving opening 11, the actuator 40 applies a contact pressure to the flat cable 70 by the upper contact beams 23 and 33 and the lower contact beams 22 and 32 by a turning operation. . As shown in FIG. 1, the actuator 40 includes an actuator main body 41 extending along the width direction of the housing 10 and a pair of side wall portions 42 provided at both ends of the actuator main body 41 in the width direction. The pair of side wall portions 42 are connected by a connecting portion 43 extending in the width direction at the front ends (the lower ends in FIGS. 1 and 4) of the side wall portions 42. A pair of through holes 44 through which the pair of left solder pegs 50 and the left solder pegs 60 can be inserted are formed in the vicinity of both ends in the width direction of the connecting portion 43, as shown in FIGS. 1 and 6. Further, as shown in FIG. 6, a rotating shaft portion 45 is provided at the through hole 44 of each actuator 40. As shown in FIG. 6, each rotation shaft portion 45 enters a notch 65 of a right solder peg 60 (also the left solder peg 50) that is press-fitted and fixed to the housing 10. As a result, the actuator 40 can rotate in the direction of arrow A from the rotation operation start position shown in FIG. 9A to the rotation operation end position shown in FIG. 9B. That is, the actuator 40 is rotatably supported with respect to the housing 10 so as to reach the rotation operation end position by rotating from the rotation operation start position to the rear side (back side in the flat cable insertion direction). . Therefore, it can be said that the flat cable connector 1 is a so-called back flip type connector. Here, the rotation operation start position is a position where the actuator 40 stands at an angle of 90 ° with respect to the horizontal direction, as shown in FIG. Further, the rotation operation end position is a position where the actuator 40 is in the horizontal direction, as shown in FIG.

  Further, as shown in FIGS. 1, 4, and 5, a plurality of first through holes 46 into which the upper contact arm 23 of the first contact 20 enters are formed in the connecting portion 43 of the actuator 40. The connecting portion 43 is formed with a plurality of second through holes 48 into which the front extension 34 of the second contact 30 enters. The plurality of first through holes 46 and second through holes 48 are alternately formed along the width direction of the connecting portion 43. And the drive part 47 is provided in the place of the 1st through-hole 46 of the connection part 43 of the actuator 40, as shown in FIG.4 and FIG9 (A), (B). The drive unit 47 drives the operating unit 24 of the first contact 20 by the rotation operation of the actuator 40, and displaces the lower contact beam 22 integral with the operating unit 24 upward. Further, as shown in FIG. 5, a separate driving portion 49 is provided at the second through hole 48 of the connecting portion 43 of the actuator 40. The drive unit 49 pushes the tip of the upper contact beam 33 of the second contact 30 from above by a turning operation, and displaces the upper contact beam 33 downward.

The pair of left solder pegs 50 and right solder pegs 60 are press-fitted and fixed to both ends of the housing 10 in the width direction, and the housing 10 is fixed to a circuit board (not shown) with solder. .
Here, the left solder peg 50 is press-fitted and fixed to the left end in the width direction of the housing 10, and the detailed structure of the left solder peg 50 is shown in FIGS. 7A, 7B, and 7C. It is. The left solder peg 50 includes a base portion 51 having a substantially rectangular flat plate shape, a press-fit portion 52, and a flat cable bending position correction portion 54, and is formed by punching and bending a metal plate. The bottom 51 of the base 51 of the left solder peg 50 is solder-fixed on the circuit board. The press-fit portion 52 extends rearward from the rear end edge of the base portion 51 and is press-fitted and fixed to the housing 10 from the front of the housing 10.

  Further, as shown in FIG. 9 (C), the flat cable bending position correcting section 54 sets the bending position of the flat cable 70 when the flat cable 70 inserted into the flat cable receiving opening 11 is bent upward. The contact 20 is isolated from the upper contact beam 23 to the front side (front side in the flat cable insertion direction). And this flat cable bending position correction | amendment part 54 is extended in the front-back direction via the connection part 53 from the upper end edge of the base 51, as shown to FIG. 7 (A), (B), (C). The flat cable bending position correcting portion 54 includes a substrate portion 54a extending in the front-rear direction from the upper end of the connecting portion 53, and a bending position correcting portion 54b extending rightward from the front end of the substrate portion 54a. When the flat cable 70 is bent upward, the bending position correcting portion 54b regulates the flat cable 70 on the front surface thereof, and isolates the bending position of the flat cable 70 from the upper contact beam 23 of the first contact 20 to the front side. . For this reason, the position of the bending position correction part 54b is separated from the upper contact beam 23 to the front side by a predetermined distance. Further, as shown in FIG. 9A, the bending position correcting portion 54b is positioned on the front side of the actuator 40 when the actuator 40 is at the rotation operation start position.

  On the other hand, the right solder peg 60 is press-fitted and fixed to the right end of the housing 10 in the width direction, and its detailed structure is shown in FIGS. 8A, 8B, and 8C. The right solder peg 60 has a mirror-symmetrical shape with the left solder peg 50, and includes a substantially rectangular flat plate-like base 61, a press-fit portion 62, and a flat cable bending position correction portion 64, and is formed by punching a metal plate. It is formed by bending. Since the base 61 has the same shape and function as the base 51 and the press-fit portion 62, the description thereof will be omitted.

  The flat cable bending position correction unit 64 of the right solder peg 60 has the same function as the flat cable bending position correction unit 54. That is, when the flat cable 70 inserted into the flat cable receiving opening 11 is bent upward, the bending position of the flat cable 70 is isolated from the upper contact beam 23 to the front side. And this flat cable bending position correction | amendment part 64 is extended in the front-back direction via the connection part 63 from the upper end edge of the base 61, as shown to FIG. 8 (A), (B), (C). The flat cable bending position correcting portion 64 includes a substrate portion 64a extending in the front-rear direction from the upper end of the connecting portion 63, and a bending position correcting portion 64b extending leftward from the front end of the substrate portion 64a. When the flat cable 70 is bent upward, the bending position correcting unit 64b regulates the flat cable 70 on the front surface thereof, and isolates the bending position of the flat cable 70 from the upper contact beam 23 to the front side. For this reason, the position of the bending position correction part 64b is separated by a predetermined distance from the upper contact beam 23 to the front side. Further, the bending position correction unit 64b is positioned on the front side of the actuator 40 when the actuator 40 is at the rotation operation start position.

  Furthermore, as shown in FIGS. 1 and 4, a plurality of load receiving portions 12 are provided below the flat cable bending position correcting portions 54 and 64 and on the front side of the lower contact beam 22 (front side in the flat cable insertion direction). It has been. Each load receiving portion 12 receives the flat cable 70 when a load is applied downward to the flat cable 70 bent upward. As shown in FIG. 1, a plurality of load receiving portions 12 are provided on the front side of the lower contact beam 22 at the same pitch as the first contacts 20 along the width direction of the housing 10. Each load receiving portion 12 is provided so as to rise from the bottom wall 10 a of the housing 10. As shown in FIG. 4, the front end surface of each load receiving portion 12 protrudes to the front side from the front surface of the bending position correcting portion 54 b. Thus, each load receiving portion 12 reliably receives the flat cable 70 when a load is applied downward to the flat cable 70 bent upward.

Next, the operation of the flat cable connector 1 will be described with reference to FIGS. 9 (A), (B), (C), and (D).
First, as shown in FIG. 9A, when the actuator 40 is in the rotation operation start position, the flat cable 70 is inserted into the flat cable receiving opening 11 from the front side (front side in the flat cable insertion direction). At this time, no contact pressure is applied to the flat cable 70 from the lower contact beam 22 and the upper contact beam 23 of the first contact 20 and from the lower contact beam 32 and the upper contact beam 33 of the second contact 30.

Next, as shown in FIG. 9B, the actuator 40 is rotated in the direction of arrow A toward the rear side (back side in the flat cable insertion direction), and the actuator 40 reaches the rotation operation end position. At this time, the drive unit 47 of the actuator 40 drives the operation unit 24 of the first contact 20 to displace the lower contact beam 22 upward. Thereby, the contact pressure with respect to the flat cable 70 by the upper contact beam 23 and the lower contact beam 22 of the first contact 20 is applied. At the same time, although not shown, the drive unit 49 of the actuator 40 presses the tip of the upper contact beam 33 of the second contact 30 from above and displaces the upper contact beam 33 downward. Thereby, the contact pressure with respect to the flat cable 70 by the upper contact beam 33 and the lower contact beam 32 of the second contact 30 is applied.
Thus, when the contact pressure with respect to the flat cable 70 by the first contact 20 and the second contact 30 is applied, the electrical connection between the flat cable 70 and the circuit board on which the flat cable connector 1 is mounted is completed. .

  Thereafter, as shown in FIG. 9C, the flat cable 70 may be twisted upward as indicated by an arrow X for some reason. In this case, the flat cable 70 is wound upward while the bending position is corrected on the front surface of the bending position correction portions 54b and 64b. Here, the lower surface of the flat cable 70 tends to be separated from the contact protrusion 22 a of the lower contact beam 22 of the first contact 20, but the lower contact beam 22 is displaced upward by the actuator 40 and the operating unit 24. Yes. For this reason, the contact protrusion 22 a of the lower contact beam 22 can follow the movement of the flat cable 70. Therefore, when the flat cable 70 is rolled upward, the lower contact beam 22 can follow the flat cable 70, so that contact failure between the lower contact beam 22 and the flat cable 70 can be avoided.

  And as shown in FIG.9 (D), a load may be added to the downward direction shown by the arrow Y with respect to the flat cable 70 bent upward for some reason. In this case, the load of the flat cable 70 is received by the load receiving portion 12 provided below the flat cable bending position correcting portions 54 and 64 and on the front side of the lower contact beam 22. For this reason, it can prevent that the upper surface of the flat cable 70 moves below and leaves | separates from the contact protrusion 23a of the upper side contact arm 23, and the contact failure of the upper side contact beam 23 can be avoided. At this time, the bending position of the flat cable 70 is isolated from the upper contact beam 23a to the front side (front side in the flat cable insertion direction) by the flat cable bending position correction portions 54 and 64. For this reason, the position of the flat cable 70 to which a load is applied is separated from the upper contact beam 23a. Therefore, it can be avoided that the load applied to the flat cable 70 is directly applied to the contact points between the upper contact beam 23 and the lower contact beam 22 and the flat cable 70. Thereby, it can prevent reliably that the upper surface of the flat cable 70 moves below and leaves | separates from the contact protrusion 23a of the upper side contact arm 23, and the contact failure of the upper side contact beam 23 can be avoided reliably.

  The flat cable bending position correcting portions 54 and 64 extend from a pair of left solder pegs 50 and right solders 60 provided at both ends in the width direction of the housing 10. For this reason, the left solder peg 50 and the right solder peg 60 have a function as a flat cable bending position correcting portion in addition to the function of fixing the housing 10 to the circuit board. Therefore, it is not necessary to separately provide the flat cable bending position correcting portions 54 and 64, and the cost can be reduced.

The load receiving portion 12 extends from the bottom wall 10 a of the housing 10 and is configured as a part of the housing 10. For this reason, it becomes unnecessary to provide the load receiving part 12 separately, and the cost can be reduced.
As mentioned above, although embodiment of this invention has been described, this invention is not limited to this, A various change and improvement can be performed.

For example, the flat cable bending position correcting portions 54 and 64 do not necessarily extend from the solder pegs 50 and 60, and may extend from the housing 10 or from the first contact 20 or the second contact 30. Good. Alternatively, the flat cable position correcting portions 54 and 64 may be members separate from the housing 10 and the first and second contacts 20 and 30.
Further, the load receiving portion 12 extends from the bottom wall 10 a of the housing 10 and is configured by a part of the housing 10, but may be configured by a member separate from the housing 10.

The flat cable connector 1 may be a front flip type in which the actuator 40 reaches the rotation operation end position by rotating from the rotation operation start position to the near side in the flat cable insertion direction.
Further, the flat cable 70 is not limited to the FPC, and may be another flat cable such as FFC.
