Description

  The present invention relates to a connector that presses a terminal against a flat electric wire such as FFC (Flexible Flat Cable) or FPC (Flexible Printed Circuits) by an actuator.

  Conventionally, a connector into which a flat electric wire such as FFC or FPC can be inserted is used. A connector of this type is disclosed in Patent Document 1. The connector of Patent Document 1 is provided with an actuator that tilts the front part of the terminal toward the flat electric wire side by pushing up the rear part of the terminal. That is, the terminal of patent document 1 has the front upper beam and front lower beam which are extended ahead from the base part, and a flat type electric wire is inserted in between. The terminal has a rear upper beam and a rear lower beam extending rearward from the base. An actuator cam portion is disposed between the rear upper beam and the rear lower beam. When the operator rotates the actuator rearward, the cam portion rotates between the rear upper beam and the rear lower beam, and pushes up the rear upper beam. As a result, the front upper beam is elastically inclined downward with its base as a fulcrum, and is pressed against the surface of the flat wire.

  In the connector described above, the rear lower beam has a convex portion at a position behind the cam portion. The convex portion restricts the rearward movement of the cam portion when the cam portion rotates. As a result, the cam portion stays between the rear lower beam and the rear upper beam when rotating, and the actuator is prevented from being detached from the connector.

JP-A-2005-78908

  However, the above-described connector has a problem that when the operator accidentally rotates the actuator forward, the actuator is detached from the connector. That is, in this type of connector, in order to increase the movable range of the actuator, the actuator is formed with a hole into which the rear upper beam fits. Since this hole penetrates the actuator, the actuator can be rotated further forward from a position standing up with respect to the connector. When the actuator is rotated forward, the rear end (lower end) of the cam portion is lifted and gets over the convex portion formed after the cam portion. As a result, the actuator may come off the connector.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a connector that can prevent the actuator from coming off even when a force is applied to rotate the actuator forward. It is in.

  In order to solve the above-mentioned problems, a connector according to the present invention is a connector into which a flat electric wire can be inserted, which extends forward from a base portion and is positioned rearward from the base portion. A plurality of terminals having a rear beam extending; Further, the connector is an actuator having a cam portion disposed below the rear beam, and a lock position where the cam portion pushes up the rear beam, and a release position where the cam portion is separated from the rear beam. And an actuator that moves to the lock position by rotating backward from the release position. Furthermore, the connector has a convex portion protruding upward at a position after the cam portion. The actuator is formed with a plurality of holes into which the rear beam is fitted when the actuator is in the release position, and the tip of the rear beam is at the bottom of at least one of the plurality of holes. A wall part is provided.

  According to the present invention, even when a force to rotate the actuator forward acts, the wall portion hits the tip of the rear beam, so that the actuator can be prevented from rotating forward from the release position, and the cam It can suppress that a part moves back beyond a convex part. As a result, it is possible to suppress the actuator from being detached from the connector. In addition, directions, such as the front and back here, are directions for showing the relative positional relationship of each member, and do not show an absolute direction when the connector is used.

  In the aspect of the invention, the tip of the rear beam may be located behind the portion of the convex portion that contacts the cam portion. When a force is applied to rotate the actuator forward from the release position, the tip of the rear beam serves as a fulcrum, so that a force to move the cam portion backward acts on the cam portion. In this aspect, since the tip of the rear beam is located behind the portion of the convex portion that contacts the cam portion, the force acting on the cam portion is rearward and obliquely downward. As a result, it is possible to more effectively suppress the cam portion from getting over the convex portion.

  In the aspect of the invention, the wall portion may block the at least one hole. According to this aspect, the tip of the rear beam comes into contact with the wall portion reliably.

  In the aspect of the invention, the actuator includes a plurality of first holes penetrating the actuator and a plurality of second holes provided with the wall portion as the plurality of holes. May be. According to this aspect, the rear beam that fits into the first hole can be lengthened. As a result, the force required for the cam portion to push up the rear beam, that is, the force required to rotate the actuator backward can be reduced.

  In this aspect, the plurality of first holes and the plurality of second holes may be alternately arranged. This can reduce the stiffness imbalance of the actuator.

  In one embodiment of the present invention, the wall portion is formed to swell rearward. Thereby, since the hole provided with the wall portion can be deepened, the post-beam that fits into the hole can be lengthened. As a result, the force required for the cam portion to push up the rear beam, that is, the force required to rotate the actuator backward can be reduced.

  In the aspect of the invention, the plurality of terminals further include a rear lower beam extending rearward from the base portion and positioned below the rear beam. In addition, the connector includes a first terminal having a connection portion attached to the circuit board on a distal end side of the rear lower beam as the plurality of terminals, and the rear lower beam having a flat upper surface formed on the distal end side. The actuator is provided with a first hole that penetrates the actuator and fits the upper beam of the first terminal, and the wall as the plurality of holes. A second hole into which the upper beam of the second terminal fits may be formed. According to this aspect, when the actuator is rotated rearward and disposed at the lock position, it is easy to avoid interference between the actuator and the first terminal.

  As shown in FIG. 2 or FIG. 3, the front connection terminal 3 is substantially H-shaped and extends forward (from the base 31 in the direction opposite to the direction in which the flat wire 100 is inserted (Y1 direction)). It has a pair of front upper beam 32 and front lower beam 33 into which the electric wire 100 can be inserted. When the flat electric wire 100 is inserted, the front upper beam 32 is located above the flat electric wire 100, and the front lower beam 33 is located below the flat electric wire 100. The front upper beam 32 is formed with a convex portion 32a that protrudes downward, and the front lower beam 33 is formed with a convex portion 33a that protrudes upward and faces the convex portion 32a. In this example, the convex part 32a and the convex part 33a are located in the middle of the front upper beam 32 or the front lower beam 33, respectively. As will be described later, when the front connection terminal 3 is elastically deformed so as to sandwich the flat electric wire 100 by rotating the actuator 2 backward, the convex portion 32a or the convex portion 33a is formed on the upper surface or the lower surface of the flat electric wire 100. It functions as a contact part which contacts the conductor part (not shown) made (refer FIG. 3).

  The front connection terminal 3 has a connection portion 36 that can be attached to a circuit board (not shown) on which the connector 1 is disposed at the tip of the front lower beam 33. Specifically, the connecting portion 36 is located in front of the front edge 11 c of the housing 11, and the lower edge of the connecting portion 36 is located at a position lower than the lower surface of the housing 11. When the connector 1 is disposed on the circuit board, the lower edge of the connection part 36 is in contact with the conductor part on the circuit board and is soldered to the conductor part.

A beam 42 and a front lower beam 43 are provided. When the flat electric wire 100 is inserted, the front upper beam 42 is located above the flat electric wire 100, and the front lower beam 43 is located below the flat electric wire 100. The front upper beam 42 is formed with a convex portion 42a protruding downward, and the front lower beam 43 is formed with a convex portion 43a protruding upward and facing the convex portion 42a in the vertical direction. In this example, the convex part 42a and the convex part 43a are located at the tip of the front upper beam 42 or the front lower beam 43, respectively, and are located in front of the convex parts 32a and 33a of the front connection terminal 3 (see FIG. 4). As will be described later, when the rear connection terminal 4 is elastically deformed so as to sandwich the flat electric wire 100 by rotating the actuator 2 backward, the convex portion 42 a or the convex portion 43 a is formed on the upper surface or the lower surface of the flat electric wire 100. It functions as a contact portion that contacts the formed conductor portion (not shown) (see FIG. 5).

  The rear connection terminal 4 has a pair of rear upper beam 44 and rear lower beam 45 extending rearward from the base 41 (the direction opposite to the extending direction of the front upper beam 42 and the front lower beam 43 (Y2 direction)). ing. The rear lower beam 45 is positioned below the rear upper beam 44 and faces the rear upper beam 44 in the vertical direction. The rear connection terminal 4 has a connection portion 46 that can be attached to the circuit board on which the connector 1 is disposed at the tip of the rear lower beam 45. Specifically, the connecting portion 46 is located behind the rear edge 11 d of the housing 11, and the lower edge of the connecting portion 46 is located lower than the lower surface of the housing 11. When the connector 1 is disposed on the circuit board, the lower edge of the connection portion 46 contacts the conductor portion on the circuit board and is soldered to the conductor portion.

  As shown in FIG. 2 or 4, the housing 11 has a plurality of insertion holes 11 a extending in the front-rear direction. The front connection terminal 3 and the rear connection terminal 4 are respectively inserted into the insertion holes 11a and are held in the insertion holes 11a. In this example, as shown in FIG. 4, a claw portion 41 a is formed on the upper edge of the rear connection terminal 4. The claw portion 41 a is hooked on the lower surface of the upper plate 12 of the housing 11. As shown in FIG. 2, in the front connection terminal 3, a claw portion 35 a is formed on the upper edge of the rear lower beam 35. Engaging portions 11b are spanned between the left and right walls of the insertion hole 11a into which the front connection terminal 3 is inserted. The engaging portion 11b is positioned between the rear upper beam 34 and the rear lower beam 35, and the claw portion 35a is hooked on the engaging portion 11b.

  As described above, the connector 1 has the actuator 2 at the rear part thereof. The actuator 2 has a rod-like cam portion 21 that is long in the left-right direction (see FIG. 7). As shown in FIGS. 2 to 5, the cam portion 21 is located below the rear upper beams 34 and 44. In this example, the front connection terminal 3 and the rear connection terminal 4 include rear lower beams 35 and 45 in addition to the rear upper beams 34 and 44, and the cam portion 21 includes the rear upper beams 34 and 44 and the rear upper beams 34 and 44. It is located between the lower beams 35 and 45. The cam portion 21 is formed so that the cross-section thereof is a long circle longer than the distance between the rear upper beams 34 and 44 and the rear lower beams 35 and 45, and the rear upper beams 34 and 44 and the rear lower beams 35 and 45 are formed. , The rear upper beams 34 and 44 are pushed up. The operation of the cam portion 21 will be described in detail later.

  As shown in FIG. 2 or FIG. 4, the actuator 2 has an operation portion 27 on the opposite side of the cam portion 21 with the rear upper beams 34 and 44 interposed therebetween. The operation unit 27 is formed to extend in the left-right direction above the rear upper beams 34 and 44.

  The actuator 2 is a thick plate-like member that is long in the left-right direction, and a plurality of holes 22, 23 arranged in the left-right direction are formed on the front surface thereof. The holes 22 and 23 are located between the cam portion 21 and the operation portion 27 (see FIG. 7). The holes 22 and 23 are alternately formed, and the position of the hole 22 in the left-right direction corresponds to the position of the rear upper beam 34 of the front connection terminal 3. When the actuator 2 is in a release position (the position of the actuator 2 shown in FIG. 2 or FIG. 4) described later, the rear upper beam 34 is fitted in the hole 22. The position of the hole 23 in the left-right direction corresponds to the position of the rear upper beam 44 of the rear connection terminal 4, and the rear upper beam 44 is fitted in the hole 23 when the actuator 2 is in the release position.

  As shown in FIG. 2, the hole 22 has an inner surface 22 b that extends from the front edge 22 a of the hole 22 in the depth direction of the hole 22 (rearward in FIG. 2) and faces the cam portion 21. . The rear upper beam 34 extends rearward along the inner surface 22 b, and the front end 34 a of the rear upper beam 34 is located deeper than the front edge 22 a of the hole 22. Similarly, as shown in FIG. 4, an inner surface 23 b that extends from the front edge 23 a of the hole 23 in the depth direction of the hole 23 and faces the cam portion 21 is formed in the hole 23. The rear upper beam 44 extends rearward along the inner surface 23 b, and the front end 44 a of the rear upper beam 44 is located deeper than the front edge 23 a of the hole 23. The vertical width of the holes 22 and 23 into which the rear upper beams 34 and 44 are fitted is larger than the vertical width of the rear upper beams 34 and 44 so that the rotation of the actuator 2 around the cam portion 21 is allowed.

  As shown in FIG. 7, the adjacent hole 22 and hole 23 are independent from each other, and a wall portion 24 is provided between the hole 22 and the hole 23 to partition them. As will be described later, the hole 23 penetrates the actuator 2 in the thickness direction, and the hole 22 is provided with a wall portion 22d for closing the hole 22.

  As shown in FIG. 4, a convex portion 45 a that protrudes upward from the rear lower beam 45 is provided on the distal end side of the rear lower beam 45 of the rear connection terminal 4 described above. The convex part 45a is located behind the cam part 21, and the rear end (lower end) 21a of the cam part 21 hits the side surface of the convex part 45a. On the other hand, as shown in FIG. 2, the rear lower beam 35 of the front connection terminal 3 is not provided with such a convex portion, and the rear lower beam 35 has a flat upper surface up to its tip. ing.

  In the actuator 2, the cam portion 21 pushes up the rear upper beams 34 and 44 (the position of the actuator 2 shown in FIGS. 3 and 5), and the cam portion 21 is located away from the rear upper beams 34 and 44. It is provided so as to be rotatable between the release position (position of the actuator 2 shown in FIGS. 2 and 4). Specifically, as shown in FIG. 2 or FIG. 4, when the actuator 2 is in the release position, the cam portion 21 is disposed obliquely on the rear lower beams 35 and 45, and the front end (upper end) 21 b of the cam portion 21 is , Located away from the rear upper beams 34 and 44. In this example, when the actuator 2 is in the release position, the cam portion 21 is disposed obliquely so that the front end 21b is positioned away from both the rear upper beams 34 and 44 and the rear lower beams 35 and 45. Has been. On the other hand, when the actuator 2 is in the locked position, as shown in FIG. 3 or 5, the cam portion 21 stands between the rear upper beams 34 and 44 and the rear lower beams 35 and 45. 44 and the rear lower beams 35 and 45 are pushed.

  As shown in FIG. 2 or FIG. 4, the operating portion 27 is located above the rear upper beams 34 and 44 in the release position. When the operator tilts the operation unit 27 backward, the actuator 2 rotates rearward from the release position and moves to the lock position. At this time, the cam portion 21 rotates between the rear upper beams 34 and 44 and the rear lower beams 35 and 45 to push up the rear upper beams 34 and 44.

  The front upper beams 32 and 42 and the rear upper beams 34 and 44 extend in opposite directions with the base portions 31 and 41 interposed therebetween, and the front upper beams 32 and 42 and the rear upper beams 34 and 44 have a rod shape. Therefore, as shown in FIG. 3 or 5, when the rear upper beams 34 and 44 are pushed up by the cam portion 21, the front upper beams 32 and 42 are elastically inclined downward with the base portions 31 and 41 as fulcrums. And the convex parts 32a and 42a of the front upper beams 32 and 42 are pressed against the upper surface of the flat electric wire 100 inserted between the front upper beams 32 and 42 and the front lower beams 33 and 43, and the convex part 32a. 42a and the convex portions 33a and 43a sandwich the flat electric wire 100. The front connection terminal 3 and the rear connection terminal 4 that are elastically deformed in this way are formed by, for example, metal punching.

  As described above, the rear lower beam 45 of the rear connection terminal 4 is formed with a convex portion 45 a that protrudes upward at a position after the cam portion 21. The rear end 21a of the cam portion 21 is in contact with the convex portion 45a. Accordingly, when the cam portion 21 rotates between the rear upper beams 34 and 44 and the rear lower beams 35 and 45, the rearward movement is restricted by the convex portion 45a. The convex portion 45a may be formed on the housing 11. For example, a convex portion that protrudes upward from the bottom plate portion 13 of the housing 11 (see FIGS. 2 to 5) between the rear connection terminal 4 and the front connection terminal 3 adjacent to each other and at a position after the cam portion 21. May be formed. Even in this case, the rearward movement of the cam portion 21 can be restricted by the convex portion.

  As shown in FIG. 7, a convex portion 26 protruding in the left-right direction is formed on the side surface of the actuator 2. On the other hand, the housing 11 has a lateral wall portion 16 that extends rearward and faces the side surface of the actuator 2 (see FIG. 1 or FIG. 6). The actuator 2 is disposed between the left and right lateral wall portions 16 and 16. As shown in FIG. 6, a convex portion 16a is formed on the inner surface of the horizontal wall portion 16, and the convex portion 26 of the actuator 2 is hooked on the convex portion 16a. The convex portions 16a and 26, together with the convex portion 45a, suppress the backward movement of the actuator 2.

  As shown in FIG. 4, the hole 23 into which the rear upper beam 44 fits penetrates the actuator 2 in the front-rear direction (thickness direction of the actuator 2). The rear upper beam 44 extends rearward along the inner surface 23 b of the hole 23, and the front end 44 a is located rearward of the rear edge 23 e of the hole 23.

  On the other hand, as shown in FIG. 2, a wall 22d is provided at the bottom of the hole 22 into which the rear upper beam 34 is fitted. This wall portion 22d hits the tip 34a of the rear upper beam 34 when the actuator 2 is disposed at the release position. In this example, the wall portion 22d extends from the operation portion 27 to the cam portion 21, and closes the hole 22 from the rear. Therefore, a bottom surface 22 e extending from the above-described inner surface 22 b toward the cam portion 21 is provided on the inner surface of the hole 22. The tip 34a of the rear upper beam 34 is in contact with the bottom surface 22e from the front.

  The actuator 2 is restricted from rotating from the release position in the direction opposite to the lock position (forward) by the wall portion 22d hitting the tip 34a of the rear upper beam 34. Specifically, as shown in FIG. 2 or FIG. 4, when a force F1 for tilting the operating portion 27 forward is applied, the tip 34a of the rear upper beam 34 comes into contact with the wall portion 22d. Acting as a fulcrum, the actuator 2 tries to rotate forward. At this time, although a force F <b> 2 for moving the cam portion 21 backward acts on the cam portion 21, the rearward movement of the cam portion 21 is restricted by the convex portion 45 a of the rear lower beam 45. As a result, the forward rotation of the actuator 2 is restricted, and the cam portion 21 is prevented from getting over the convex portion 45a.

  As shown in FIG. 2 or FIG. 4, the position of the tip 34a of the rear upper beam 34 in the front-rear direction is located rearward from the position of the portion that contacts the cam portion 21 of the convex portion 45a. In this example, the rear end 21a of the cam portion 21 hits the side surface of the convex portion 45a. The tip 34a of the rear upper beam 34 is located behind the side surface of the convex portion 45a. As a result, even when a forward force F1 is applied to the operation portion 27, the cam portion 21 is more difficult to get over the convex portion 45a. In other words, when the force F1 for tilting the operation unit 27 forward is applied, the actuator 2 tries to rotate forward with the tip 34a and the fulcrum. At this time, the direction of the force F2 acting on the side surface of the convex portion 45a from the cam portion 21 is rearward and obliquely downward because the tip 34a of the rear upper beam 34 is located rearward from the side surface of the convex portion 45a. . Therefore, it is difficult for the cam portion 21 to get over the convex portion 45a.

  As shown in FIG. 6, the wall 22d is formed so as to swell rearward. In this example, the outer surface 22f of the wall portion 22d is located rearward of the rear edge 23e of the hole 23 and the rear end (lower end) 21a of the cam portion 21 (see FIG. 4). Thereby, the hole 22 can be deepened, and the rear upper beam 34 fitted into the hole 22 can be lengthened.

  As described above, the rear connection terminal 4 is provided with the convex portion 45 a and the connection portion 46. As shown in FIG. 5, when the actuator 2 is disposed at the lock position, the hole 23 is located above the convex portion 45 a and the connecting portion 46. By forming the hole 23 in this way, interference between the connecting portion 46 and the actuator 2 and interference between the convex portion 45a and the actuator 2 can be avoided. In particular, in this example, when the actuator 2 is disposed at the locked position, the top of the convex portion 45 a and the upper edge of the connecting portion 46 are located at a position slightly higher than the rear edge 23 e of the hole 23. Further, when the actuator 2 is disposed at the lock position, the wall portion 22d provided in the hole 22 is located between the two adjacent connection portions 46. By forming the hole 22 in this way, the wall portion 22d can be greatly expanded rearward and the hole 22 can be deepened without causing interference between the connection portion 46 and the wall portion 22d.

  As described above, the connector 1 includes a plurality of front connection terminals having a front upper beam 32 extending forward from the base 31 and positioned above the flat wire 100 and a rear upper beam 34 extending rearward from the base 31. 3 is provided. The actuator 2 has a cam portion 21 disposed below the rear upper beam 34, and a lock position where the cam portion 21 pushes up the rear upper beam 34, and a release position where the cam portion 21 is separated from the rear upper beam 34. Between the release position and the rear end, and the rear end is moved to the lock position. Further, the connector 1 is provided with a convex portion 45 a that protrudes upward at a position after the cam portion 21. The actuator 2 is formed with a plurality of holes 22 into which the rear upper beam 34 is fitted when the actuator 2 is in the release position, and a wall 22d where the tip 34a of the rear upper beam 34 abuts at the bottom of the hole 22. Is formed.

  According to such a connector 1, even when a force for rotating the actuator 2 forward acts, the wall 22d hits the tip 34a of the rear upper beam 34, so that the actuator 2 rotates forward from the release position. This can prevent the cam portion 21 from moving backward beyond the convex portion 45a. As a result, it is possible to suppress the actuator 2 from being detached from the connector 1.

  In addition, this invention is not restricted to the connector 1 demonstrated above, A various change is possible. For example, in the above description, the wall 22 d provided at the bottom of the hole 22 blocks the hole 22 from the rear. However, the wall portion 22d does not have to block the hole 22. For example, although the wall portion 22d extends downward from the operation portion 27, a gap may be provided between the cam portion 21 and the wall portion 22d. That is, a hole smaller than the hole 22 may be formed in the wall portion 22d, and the hole may penetrate the wall portion 22d.

  Further, the connector 1 was provided with a hole 23 penetrating the actuator 2. However, the bottom portion of the hole 23 may be provided with a wall portion against which the tip 44a of the rear upper beam 44 of the rear connection terminal 4 hits.

  In the connector 1, the wall portion 22 d is provided in all the holes 22 into which the rear upper beam 34 of the front connection terminal 3 is fitted. However, the wall 22 d may be provided only in a part of the hole 22.

  Further, in the connector 1, the wall portion 22d is formed such that the tip 34a of the rear upper beam 34 hits the wall portion 22d from the front. However, the inner surface of the wall 22d may be curved in accordance with the shape of the tip 34a. FIG. 8 is a cross-sectional view of the connector 101 according to this embodiment. In the figure, the same reference numerals are given to the same portions as described above. The connector 101 has an actuator 102. In the actuator 102, a curved surface 22 g is formed as the inner surface of the wall portion 22 h provided at the bottom of the hole 22.
