Description

  The present invention relates to an electrical connector for a flat cable.

  Conventionally, an electric connector for a flat cable for connecting a flat cable typified by a flexible flat cable (FFC) or a flexible printed circuit (FPC) to a circuit board is known. For example, Patent Document 1 discloses an FPC connector. This FPC connector includes a contact held by an insulator and an actuator rotatably attached to the insulator. The contact has an upper contact portion that bears contact with the upper side of the FPC and a lower contact portion that bears contact with the lower side. A pair of contact parts are connected via the connection spring part, and the spring part is extended behind the connection spring part of the upper contact part. When the spring portion behind the upper contact portion is driven by the rotating actuator, the upper contact portion is lowered to contact the FPC together with the lower contact portion.

  Patent Document 2 also discloses a flat flexible cable connector that includes a contact portion, a casing, and an actuator. The contact portion has a first contact beam disposed on the upper side of the cable and a second contact beam disposed on the lower side. The second contact beam is supported by a base beam fixed to the housing via the connecting portion, and the first contact beam is connected to the second contact beam. When the rear end protrusion of the second contact beam is driven by the actuator, the first contact beam is lowered and contacts the cable together with the second contact beam.

  In the FPC connector of Patent Document 1, the lower contact portion of the contact is fixed to the insulator. As a result, when the FPC is turned upward, that is, when the outer portion of the connector in the FPC is lifted upward, the contact portion on the lower side of the contact cannot follow the FPC, which may cause a contact failure.

  The 2nd contact beam shown by patent document 2 is supported by the connection part, and is movable. However, the rear end protrusion of the second contact beam is locked by the actuator. Therefore, when the cable is twisted upward, the second contact beam cannot follow and there is a risk of causing a contact failure.

  An object of the present invention is to solve the above-described problems and provide an electric connector for a flat cable with improved contact reliability.

The electrical connector for a flat cable of the present invention that achieves the above object is as follows.
A housing that accepts insertion of a flat cable with the face up and down from the front,
A fixing portion fixed to the housing; a lower beam extending forward from the fixing portion along a lower surface of the flat cable received in the housing and in contact with the lower surface of the flat cable; and the lower beam In the middle of extending forward from the fixed portion, the lower beam is branched from the lower beam, and a receiving portion for receiving the end portion of the flat cable is formed between the lower beam and the upper portion of the flat cable. A contact having an actuating beam and an upper beam extending forward from and over the actuating beam from the fixed portion to bear contact with the upper surface of the flat cable, and a cam acting on the actuating beam And receiving the flat cable by releasing the action of the cam portion on the working beam. The cable receiving posture that opens in the inserted state, and by pushing up the working beam by the cam portion, the flat cable received in the receiving portion is pressed against the lower beam from below so that the flat cable is connected to the upper beam. An actuator is provided that is rotatable between a cable fixing posture held between the lower beam and the lower beam.

  In the electric connector for a flat cable of the present invention, the actuator pushes up the working beam, so that the lower beam comes into contact with the flat cable so as to press from below. For this reason, even when the flat cable is rolled upward, the lower beam follows the flat cable. Therefore, in the flat cable electrical connector according to the present invention, the displacement amount of the lower beam is larger than the case where the lower beam is not pushed up by the actuator. High reliability.

Here, in the electric connector for a flat cable according to the present invention, the flat cable is adjacent to the edge side terminal away from the edge and the edge side terminal near the edge at the end portion received by the housing. The rear terminal of the position is alternately arranged in the width direction along this edge,
The contact shares the contact with the back terminal,
The electrical connector for the flat cable further includes
A second fixing portion fixed to the housing and a second receiving portion that branches from the second fixing portion and receives the flat cable between them are formed to the lower surface and the upper surface of the flat cable, respectively. A second lower beam and a second upper beam that are in contact with each other, and comprising a second contact that shares the contact with the edge terminal,
The actuator is further a second cam portion that acts on the second upper beam, and in the cable receiving posture, the action on the second upper beam is released to make the second receiving portion the The flat cable received in the second receiving portion is pushed from above onto the second upper beam by opening the flat cable in a state of receiving and pressing down the second upper beam in the cable fixing posture. It is preferable to have a second cam portion for holding the flat cable between the second upper beam and the second lower beam.

  The contacts that share the contact with the back terminal and the second contacts that share the contact with the edge terminal are alternately arranged so that the flat cable ends up with the upward beam of the contact's lower beam. A force and a downward force due to the upper beam of the second contact are alternately applied. For this reason, the holding force of a flat cable increases.

  As described above, according to the present invention, an electrical connector for a flat cable with improved contact reliability is realized.

  The first contact 3 includes a fixing portion 31, a solder connection portion 32, a lower beam 33, an operation beam 34, and an upper beam 35. The first contact 3 is a member formed by punching a metal plate, and the fixing portion 31, the solder connection portion 32, the lower beam 33, the working beam 34, and the upper beam 35 are integrally formed. Yes. The first contact 3 is inserted into the housing 1 from the rear of the housing 1 toward the front F. A locking claw 311 protrudes from the fixed portion 31. The first contact 3 is supported by the housing 1 by press-fitting and fixing the fixing portion 31 to the housing 1. The solder connection portion 32 is exposed on the lower surface of the housing 1. The first contact 3 is electrically connected to the circuit board by the solder connection portion 32 being solder-connected to a circuit board (not shown).

  The lower beam 33 is a cantilever spring that extends forward F from a fixed portion 31 that is closer to the rear in the housing 1. The lower beam 33 extends substantially along the bottom wall 11 of the housing 1 and is in contact with the lower surface of the FPC 9. A contact 331 that contacts the lower surface of the FPC 9 protrudes upward U from the tip of the lower beam 33.

  The working beam 34 is a portion of the lower beam 33 that is branched and extended from the lower beam 33 while extending from the fixed portion 31 toward the front F. The working beam 34 forms a receiving portion 3 a that receives the end portion 92 of the FPC 9 with the lower beam 33, and extends to the upper side of the FPC 9.

  A first cam portion 22 is provided at a portion of the actuator 2 where the first contact 3 is disposed. The first cam portion 22 of the actuator 2 is cam-engaged with the tip portion of the operating beam 34 of the first contact 3.

  The upper beam 35 of the first contact 3 is a cantilever spring that is separated from the fixed portion 31 and extends forward F. The upper beam 35 extends separately from the lower beam 33 from the fixed portion 31. The upper beam 35 passes over the working beam 34 and extends forward F beyond the working beam 34 beyond the working beam 34. A tip portion of the upper beam 35 is bent downward D to form a contact 351 that contacts the upper surface of the FPC 9.

  FIG. 7 is a cross-sectional view for explaining the operation of the actuator and the first contact shown in FIG. Part (A) of FIG. 7 shows a state in which the end 92 of the FPC 9 is inserted, Part (B) shows a state during the operation of the actuator, and Part (C) shows a state in which the actuator is in a fixed posture. .

  Part (A) of FIG. 7 shows the actuator 2 in a receiving state. In this state, the first cam portion 22 of the actuator 2 is released from the action on the actuation beam 34 and is open to receive the FPC 9 by the receiving portion 3a. As shown in Part (A) of FIG. 7, when the actuator 2 rotates backward B as shown in Part (B) of FIG. 7 with the end 92 of the FPC 9 received in the housing 1, the first cam The portion 22 rotates and pushes the tip end portion of the working beam 34 which is a cam follower upward U. Since the working beam 34 extends from the middle of the lower beam 33, when the working beam 34 is pushed up, the narrow base portion 31 a near the fixed portion 31 is elastically deformed, and the lower beam 33, particularly the contact 331. A tip portion having a ridge rises while rotating upward U around the root portion 31a. The contact 331 of the lower beam 33 is in contact with the lower surface of the end 92 of the FPC 9, more specifically, the inner terminal (not shown) disposed just behind the inner terminal 93 shown in FIG. Press the part upward U. As a result, the upper surface of the end portion 92 of the FPC 9, more specifically, the rear side terminal 93 shown in FIG. 1 contacts the contact 351 of the upper beam 35. In the state shown in part (C) of FIG. 7, the end 92 of the FPC 9 is sandwiched between the lower beam 33 and the upper beam 35. That is, the lower beam 33 and the upper beam 35 are in elastic contact with the end portion 92 of the FPC 9, and the end portions 92 are biased toward each other by elastic force. Therefore, the first contact 3 reliably contacts the terminal on both the upper surface and the lower surface of the FPC 9. Further, in the state shown in Part (C) of FIG. 7, the upper beam 35 is in contact with the actuator 2 that has fallen into the fixed posture at a portion closer to the fixed portion 31 than the tip.

[Second contact]
8 is a view showing a cross section taken along line 8-8 passing through the vicinity of the second contact of the FPC connector C shown in FIG.

  The second contact 4 includes a fixing portion 41, a solder connection portion 42, a lower beam 43, a reinforcing beam 44, and an upper beam 45. The second contact 4 is a member formed by punching a metal plate, and the fixing portion 41, the solder connection portion 42, the lower beam 43, the reinforcing beam 44, and the upper beam 45 are integrally formed. Yes. Here, the fixed portion 41, the lower beam 43, and the upper beam 45 correspond to examples of the second fixed portion, the second lower beam, and the second upper beam, respectively, according to the present invention.

  The second contact 4 is inserted into the housing 1 from the front of the housing 1 toward the rear B, contrary to the first contact 3 (see FIG. 6). A locking claw 411 protrudes from the fixed portion 41. The second contact 4 is supported by the housing 1 by press-fitting and fixing the fixing portion 41 to the housing 1. The fixed portion 41 of the second contact 4 has a shape that is bent in an L shape as a whole, and extends downward in the housing 1 from the rear portion in the housing 1 to the front F. The solder connection portion 42 is provided at the front end of the front portion F of the fixing portion 41 and is exposed on the lower surface of the housing 1. The solder contact portion 42 is soldered to a circuit board (not shown), whereby the second contact 4 is electrically connected to the circuit board.

  The lower beam 43 is a cantilever spring extending from the front F front end of the fixed portion 41 to the rear B. The lower beam 43 extends along the lower surface of the FPC 9 (see FIG. 4) received in the housing 1 and is in contact with the lower surface of the FPC 9. A contact 431 that contacts the lower surface of the FPC 9 protrudes upward U from the tip of the lower beam 43.

  The upper beam 45 is a cantilever spring extending from the rear portion of the fixed portion 41 to the front F. The upper beam 45 extends separately from the lower beam 43 from the fixed portion 41. The upper beam 45 forms a second receiving portion 4 a that receives the end portion 92 of the FPC 9 between the upper beam 45 and extends to the upper side of the FPC 9. A contact point 451 that contacts the upper surface of the FPC 9 protrudes downward D from the tip of the upper beam 45.

  A second cam portion 23 is provided at a portion of the actuator 2 where the second contact 4 is disposed. The second cam portion 23 of the actuator 2 is cam-engaged with the upper beam 45 of the second contact 4.

  The reinforcing beam 44 is a cantilever spring extending forward F from the upper end of the rear portion of the fixed portion 41. The reinforcing beam 44 extends separately from both the upper beam 45 and the lower beam 43. The reinforcing beam 44 extends upward from the upper beam 45 and is in contact with the upper portion of the second cam portion 23. The reinforcing beam 44 presses the second cam portion 23 that pushes down the upper beam 45 from above.

  FIG. 9 is a cross-sectional view for explaining the operation of the actuator and the second contact shown in FIG. Part (A) in FIG. 9 shows a state in which the end portion 92 of the FPC 9 is inserted, Part (B) shows a state during the operation of the actuator, and Part (C) shows a state in which the actuator is in a fixed posture. .

  Part (A) of FIG. 9 shows the actuator 2 in an accepted state. In this state, the second cam portion 23 of the actuator 2 releases the action on the upper beam 45, and the receiving portion 4a is open to receive the FPC 9. As shown in Part (A) of FIG. 9, when the actuator 2 rotates rearward B as shown in Part (B) of FIG. 9 with the end 92 of the FPC 9 received in the housing 1, the second cam The portion 23 rotates and pushes the tip portion of the upper beam 45, which is a cam follower, downward D. The contact point 451 of the upper beam 45 contacts the upper surface of the end portion 92 of the FPC 9, more specifically, the edge side terminal 94 shown in FIG. 1 and presses the contacted portion downward D. As a result, the lower surface of the end portion 92 of the FPC 9, more specifically, an end-side terminal (not shown) arranged just behind the end-side terminal 94 shown in FIG. . In the state shown in part (C) of FIG. 9, the end 92 of the FPC 9 is sandwiched between the lower beam 43 and the upper beam 45. That is, the lower beam 43 and the upper beam 45 are in elastic contact with the end portion 92 of the FPC 9, and the end portions 92 are urged toward each other by elastic force. Therefore, the second contact 4 reliably contacts the terminal on both the upper surface and the lower surface of the FPC 9. In the state shown in part (C) of FIG. 9, the reinforcing beam 44 that presses the second cam portion 23 from above is in contact with the actuator 2 that has fallen.

[FPC fixing]
As shown in part (A) of FIG. 7 and part (A) of FIG. 9, after the end portion 92 of the FPC 9 is inserted into the FPC connector C in which the actuator 2 is in the receiving posture, the actuator 2 is in the fixed posture. When the rotation is performed, the end 92 of the FPC 9 is fixed to the FPC connector C. Specifically, of the end portion 92 of the FPC 9 shown in FIG. 1, the portion of the end side terminal 94 arranged in the width direction W at a position near the end 92a is the second contact shown in Part (C) of FIG. 4 is sandwiched between the lower beam 43 and the upper beam 45. Further, among the end portions 92 of the FPC 9 shown in FIG. 1, the portion of the back side terminal 93 that is separated from the end edge 92a and is arranged in the width direction W is the upper beam of the first contact 3 shown in Part (C) of FIG. 35 and the lower beam 33. Of the end portion 92 of the FPC 9, the portion of the edge-side terminal 94 and the portion of the back-side terminal 93 are sandwiched so that the posture of the FPC 9 is fixed. Furthermore, as shown in FIG. 4, the retaining protrusion 95 of the FPC 9 whose posture is fixed is locked to the FPC locking claw 54 provided on the peg 5, thereby preventing the FPC 9 from being detached. .

  FIG. 10 is a cross-sectional view illustrating a state in which the FPC is rolled up.

  FIG. 10 shows a state in which the FPC 9 fixed to the FPC connector C is turned upward, that is, a state in which the outer portion of the connector is lifted by receiving an upward force U away from a circuit board (not shown). Yes. In this case, the end portion 92 of the FPC 9 is also lifted upward U, and the end portion 92 of the end portion 92 (see FIG. 1) close to the insertion port of the FPC connector C is particularly lifted.

  In the FPC connector C of the present embodiment, the lower beam 33 of the first contact 3 that contacts the portion of the back terminal 93 (see FIG. 1) is driven by the working beam 34 and the end 92 of the FPC 9 is moved upward U. Is energized. For this reason, the lower beam 33 follows the upward displacement of the end portion 92 of the FPC 9. Therefore, a high contact pressure on the end 92 by the lower beam 33 as well as the upper beam 35 is maintained. Therefore, even if the FPC 9 is turned upward, contact is maintained on both the upper surface and the lower surface of the end portion 92, so that contact reliability is high.

  Further, when the FPC 9 is rolled upward, the upper beam 35 is lifted upward U by the FPC 9. The upper beam 35 lifts the actuator 2 upward U because the portion closer to the fixed portion 31 than the tip is in contact with the actuator 2 in a fixed posture. Although the actuator 2 is held by the housing 1 via the peg 5 (see FIG. 5), the actuator 2 is made of resin, so that it is elastically displaced upward U by receiving a force. At this time, the actuator 2 pushes the tip of the working beam 34 further upward through the first cam portion 22. As the operating beam 34 is pushed up, the contact 331 of the lower beam 33 is further raised. In this way, the lower beam 33 follows the rise of the FPC 9. Therefore, contact reliability is further increased.

  In the FPC connector C of the present embodiment, the first contacts 3 and the second contacts 4 are alternately arranged in the left-right direction RL, that is, the width direction W. In a state where the FPC 9 is fixed to the FPC connector C, the first contact 3 holds the end 92 by the force by which the lower beam 33 pushes the end 92 of the FPC 9 upward U, and the second contact 4 45 clamps the end 92 by a force that pushes the end 92 downward D. Since an upward U force and a downward D force are alternately applied to the end portion 92 in the width direction W, the holding force of the end portion 92 by the first contact 3 and the second contact 4 increases.

  In the above-described embodiment, the FPC connector C that connects the FPC 9 in which the edge side terminals 94 and the back side terminals 93 are arranged in two rows is shown. However, the present invention is not limited to this, and for example, a flat cable having terminals arranged in a row may be targeted.

  In the above-described embodiment, an FPC connector C including both the first contact 3 and the second contact 4 is shown as an example of the flat cable electrical connector according to the present invention. However, the present invention is not limited to this. For example, the flat cable electrical connector may include only the first contact 3.

  In the present embodiment, an FPC connector C intended for an FPC is shown. However, the electrical connector for a flat cable of the present invention is not limited to an FPC, but may be a flexible flat member having a conductor, such as an FFC. Also good.

  Further, the number of contacts included in the flat cable electrical connector may be 40 or less, or 42 or more.

  In the present embodiment, an FPC connector C having a so-called back flip type actuator 2 is shown. However, the electric connector for flat cable of the present invention may have a front flip type actuator.
