In addition, a guide groove 38 corresponding to the guide groove 32 ′ formed in the support part 32 is formed at a position corresponding to the opposite side of the contact protrusion 37. That is, both ends of the drive cam 47 are rotated in the two guide grooves 32 ′ and 38, respectively, so that the rotation of the drive cam 47 can be achieved.

Next, the locking member 40 will be described. The locking member 40 is coupled to the housing 10 and serves to deform the first and second terminals 20 and 30 through rotation. That is, the locking member 40 lifts one end of the operation beams 26 and 36 of the first and second terminals 20 and 30 in a direction away from the mounting beams 21 and 31 through rotation, The contact protrusions 27 and 37 formed at the other ends of the actuating beams 26 and 36 press the surface of the flexible cable C.

The exterior and skeleton of the locking member 40 is formed by the body portion 41. The body portion 41 has a substantially rectangular parallelepiped shape as shown, and is a portion exposed outside the operating space of the housing 10.

One end of the body portion 41 is provided with an insertion portion 42. The insertion part 42 is a part which is selectively inserted into the insertion spaces 12 and 13 of the housing 10 to substantially operate the first and second terminals 20 and 30.

The insertion part 42 is provided with a guide boss 45. The guide boss 45 protrudes at both ends of the insertion part 42, and contacts the guide jaw 15 provided on the inner surface of the housing 10 to guide the movement of the locking member 40. Play a role.

The insertion part 42 is provided with a drive cam 47. The driving cam 47 substantially elastically deforms the first and second actuating beams 26 and 36 of the first and second terminals 20 and 30. As shown in FIG. 6, the driving cam 47 has an elliptical shape. Is formed. More precisely, the width and height of the cross section of the drive cam 47 are different from each other, so that the height of the cross section of the cross section of the drive cam 47 varies as it is rotated. As a result, the operation beams 26 and 36 of the first and second terminals 20 and 30 are elastically deformed. As shown in FIG. 2, the driving cams 47 are formed in a number corresponding to the number of the first and second terminals 20 and 30.

In this case, as shown in FIG. 6, the driving cam 47 inserted between the seating beam 21 and the operation beam 26 of the first terminal 20 has a flat portion 47 ′ at one side thereof. The planar portion 47 'has a shape in which a portion of the drive cam 47 having an approximately elliptical shape is cut off, and the planar portion 47' serves to reduce the overall height of the drive cam 47.

Hereinafter, the operation of the flexible cable connector according to the present invention as described above will be described in detail with reference to the drawings.

First, the process of assembling the flexible cable connector according to the present invention will be described with reference to FIG. 7. For reference, Figure 7 (a) to Figure 7 (d) is a cross-sectional view in which the connector is cut in different positions, the left side is inserted into the terminal, and the right side is shown that the guide boss 45 of the locking member is moved Shown together.

The operator inserts the first terminal 20 into the first insertion space 12 of the housing 10. That is, the first terminal 20 is inserted into the first insertion space 12 of the housing 10 by moving the first terminal 20 from the right side to the left side based on FIG. 7 (a). At this time, the hook groove 23 ′ formed in the seating leg 23 of the first terminal 20 is hooked to the housing 10 to restrict the insertion degree of the first terminal 20.

When the first terminal 20 is inserted, the operator inserts the locking member 40 in the same direction as the direction in which the first terminal 20 is inserted. At this time, the locking member 40 is inserted in a state orthogonal to the housing 10, as shown in Figure 7 (a). More precisely, the locking member 40 is inserted while allowing the driving cam 47 of the locking member 40 to be inserted between the first actuating beam 26 and the first seating beam 21 of the first terminal 20. Is moved.

At this time, referring to Figure 6, the first mounting beam 26 and the first mounting beam 21, more precisely the first mounting beam from the tip of the fixing hanger 28 of the first working beam 26 Since the interval H1 between the 21 is formed smaller than the thickness H of the drive cam 47, the drive cam 47 is inserted while slightly elastically deforming the fixed hook portion 28. Therefore, once the driving cam 47 is positioned between the first actuating beam 26 and the first seating beam 21, the driving cam 47 is prevented from being separated by being caught by the fixed hanger part 28 which is restored in a circular shape.

This appearance is also shown in Fig. 7 (a). That is, the first actuating beam 26 is elastically deformed by the driving cam 470. In this case, the guide boss 45 of the locking member 40 is a guide jaw provided on the inner surface of the housing 10. 15 is moved along the inlet portion 15a, so that the guide boss 45 can no longer be lifted upward based on the drawing, which means that the driving cam 47 of the locking member 40 Interfering with the fixed hanger portion 28 of the terminal 20 is to prevent excessive elastic deformation.

In FIG. 7B, the locking member 40 is further inserted such that the driving cam 47 passes through the fixing hanger 28 and the first seating beam 21 and the first working beam 26. The state located in between is shown. In this case, the first terminal 20 is in a circular state.

At the same time, the guide boss 45 of the locking member 40 is spaced apart from the inlet 15a of the guide jaw 15 on one side of the seating jaw.

Next, referring to FIG. 7C, the operator lifts the locking member 40 upward. In this case, a gap is formed between the driving cam 47 of the locking member 40 and the first seating beam 21 of the first terminal 20. This spacing is shown exactly in FIG. 6 (see 'H3' in FIG. 6).

At this time, looking at the right side of Figure 7 (c), it is shown that the guide boss 45 of the locking member 40 is hooked to the seating portion (15b) of the guide jaw (15) of the housing (10) have. That is, the locking member 40 is guided to the seating portion 15b so that it can no longer be lifted and can be accurately fixed to the designed position.

In this state, the operator inserts the second terminal 30 into the second insertion space 13 of the housing 10. More precisely, the second terminal 30 is moved in the direction opposite to the direction in which the first terminal 20 is inserted to be accommodated in the second insertion space 13.

When the second terminal 30 is completely inserted into the second insertion space 13, the support part 32 formed in the second seating beam 31 of the second terminal 30 is formed of the locking member 40. The gap between the driving cam 47 and the first mounting beam 21 of the first terminal 20 is filled. The height H3 of the support part 32 corresponds to the height H3 between the driving cam 47 of the locking member 40 and the first seating beam 21 of the first terminal 20. It is possible to have.

In this case, even when the operator releases the locking member 40, the driving cam 47 of the locking member 40 is supported by the support part 32, thereby preventing the locking member 40 from falling. do. In addition, the driving cam 47 is prevented from escaping between the first actuating beam 26 and the first seating beam 21 of the first terminal 20.
