(bending member 81)

The second terminal 51B provided at one end of the bending member 81 in this embodiment has a partial shape different from the second terminal 51B in the first embodiment.

As shown in FIG. 20 , the second terminal 51B in this embodiment includes a base 52 connected to an end of the bending member 81 and a body portion extending from the base 52 toward the front end ( 56) are included. And the said body part 56 contains the latching piece 55 formed so that it may protrude in one direction crossing the axial direction of the bending member 81 on the base part 52 side.

In addition, the main body portion 56 includes a pair of side walls 56a extending toward the ends in a state facing each other, a deformation preventing wall 56b formed at the ends of the side walls 56a, and facing each other. It has a pair of contact pieces 54 extending toward the front end in the state. The front end portion of the main body portion 56 is formed by a pair of side walls 56a and a pair of contact pieces 54 so as to form a quadrangular shape when viewed from the insertion direction of the bending member 81. In addition, the deformation preventing wall 56b is a rectangular tubular member continuous to form a quadrangular shape when viewed from the insertion direction of the bending member 81 .

In addition, the body portion 56 crosses in the axial direction of the bending member 81 at a portion adjacent to the locking piece 55, and also intersects in the protruding direction of the locking piece 55 In 20(a) and (c), it has a pair of engaging protruding pieces 57 protruding toward both left and right sides.

Accordingly, the engagement protruding piece 57 is accommodated in its entirety in the protruding piece engaging groove 44a and does not protrude from the second housing-side surface 42c of the alignment member 41, so that the alignment member ( When attaching the second housing 11B to 41), there is no obstruction. In addition, if the length 11 is made longer, for example, about twice the length L, the number of bending members 81 is large, and even if there is a tolerance in the position of the engaging protruding piece 57, as shown in FIGS. 21 and 22 In this state, it is possible to prevent all of the engaging protruding pieces 57 from protruding from the second housing-side surface 42c of the alignment member 41.

(assembly order)

The assembly procedure of the connector 10 in this embodiment is demonstrated.

The aligning member 41 and the first housing 11A are overlapped, and the first terminal 51A of each flexural member 81 is inserted into each flexural member insertion cavity 44 of the aligning member 41. The procedure from passing through to inserting into each terminal accommodating cavity 13 of the first housing 11A is the same as that of the first embodiment, so the description thereof is omitted. In the first embodiment, the convex portion 45 for positioning and the concave portion 11f for positioning are interlocked so that the alignment member 41 and the first housing 11A are overlapped. In the embodiment, an anti-rotation pawl 48 protruding downward from the first housing-side surface 42d of the body portion 42 is opened at the center of the base end surface 11c of the base end portion 11a. It is inserted into the hole 18, and the first housing-side surface 42d and the base end surface 11c abut or come close to each other so that the alignment member 41 and the first housing 11A are overlapped. By inserting the anti-rotation pole 48 into the anti-rotation hole 18, the relative rotation of the aligning member 41 and the first housing 11A is prevented.

18, on the side surface of the base portion of the anti-rotation pawl 48 protruding downward from the first housing-side surface 42d of the alignment member 41, there are ribs protruding outward. Since 48a is formed, when the anti-rotation pawl 48 is inserted into the anti-rotation hole 18 of the first housing 11A, the rib 48a is lightly press-fitted to the inner wall surface of the anti-rotation hole 18. In this state, the alignment member 41 is fixed to the first housing 11A. Accordingly, an operation of inserting the first terminal 51A into the terminal accommodating cavity 13 of the first housing 11A can be stably performed. In addition, since the rib 48a is only lightly press-fitted into the inner wall surface of the anti-rotation hole 18, there is no problem with the operation of separating the aligning member 41 from the first housing 11A, which is performed thereafter. .

Next, the aligning member 41 is separated from the first housing 11A, moved relatively along the bending member 81 toward the second terminal 51B, and each second terminal 51B is moved along the body portion 42 ) from the side of the second housing-side surface 42c through the respective bending member insertion cavities 44, and aligning them to obtain a state as shown in FIGS. 21 and 22. In this state, in each second terminal 51B, the base 52 and the locking piece 55 are accommodated in the bending member insertion cavity 44, and the pair of engaging protruding pieces 57 are the second terminals 51B. It is accommodated in the protruding piece engaging groove 44a formed at the end of the housing-side face 42c side, and engages with the protruding piece engaging groove 44a. Accordingly, each of the aligned second terminals 51B can no longer move within the bending member insertion cavity 44 toward the first housing-side surface 42d, and as shown in FIGS. 21 and 22, contact The piece 54, the side wall 56a, and the deformation preventing wall 56b rest against the alignment member 41 in a state in which they protrude upward from the second housing side face 42c. In addition, in FIGS. 21 and 22, it should be noted that illustration of some bending members 81 is omitted for convenience of description.

Then, as shown in Fig. 23, the second housing 11B is aligned with respect to the alignment member 41. Specifically, the base end face 11c faces the second housing-side face 42c in parallel, and the anti-rotation hole 18 opening at the center of the base end face 11c is formed from the second housing-side face 42c. Opposite to the anti-rotation pawl 48 protruding upward, each terminal accommodating cavity 13 opened in the base end face 11c faces each second terminal 51B.

Next, the second housing 11B is relatively moved toward the alignment member 41, the anti-rotation pawl 48 is inserted into the anti-rotation hole 18, and upward from the second housing side face 42c. Each of the second terminals 51B protruding toward each other is inserted into each of the terminal accommodating cavities 13, and the second housing-side face 42c and the base end face 11c are brought into or close to each other, so that the alignment member 41 and the second terminal 51B are brought into contact with each other. The housing 11B is overlapped. By inserting the anti-rotation pole 48 into the anti-rotation hole 18, relative rotation of the aligning member 41 and the second housing 11B is prevented. Further, the anti-rotation pawl 48 may be press-fitted into the anti-rotation hole 18 . As a result, each of the second terminals 51B is accommodated in the respective corresponding terminal accommodating cavity 13 in the second housing 11B.

18, on the side surface of the base portion of the anti-rotation pawl 48 protruding upward from the second housing-side surface 42c of the alignment member 41, there are ribs protruding outward. Since 48a is formed, when the anti-rotation pawl 48 is inserted into the anti-rotation hole 18 of the second housing 11B, the rib 48a is lightly press-fitted to the inner wall surface of the anti-rotation hole 18. In this state, the alignment member 41 is fixed to the second housing 11B. Accordingly, an operation of inserting the second terminal 51B into the terminal accommodating cavity 13 of the second housing 11B can be stably performed. In addition, the shape of the rib 48a is changed so that the rib 48a is strongly pressed into the inner wall surface of the anti-rotation hole 18, thereby strengthening the fixing force of the alignment member 41 to the second housing 11B. If so, it is also possible to omit the first attachment 21A and the second attachment 21B used thereafter.

And the procedure up to this point can also be performed by sliding the 1st housing 11A, the alignment member 41, or the 2nd housing 11B along the guide member. For example, a work bench equipped with a straight rail as a guide member on a horizontal upper surface is prepared. Then, with the first housing 11A, the alignment member 41 and the second housing 11B facing sideways, respectively, the groove portion 11g formed on the outer circumferential surface of the proximal end 11a of the first housing 11A, the alignment member A groove portion 42b formed on the outer circumferential surface of the main body portion 42 of 41 and a groove portion 11g formed on the outer circumferential surface of the tip portion 11b of the second housing 11B are slidably fitted to the rail. In this way, by sliding the first housing 11A, the alignment member 41 or the second housing 11B along one rail, they can be brought closer to or separated from each other.

Subsequently, as shown in FIGS. 24 to 26, the alignment member 41 overlapping the second housing 11B is attached to the second housing 11B using the first attachment 21A and the second attachment 21B. Mount it. The first attachment 21A and the second attachment 21B each have a body portion 22 having an overall shape such as a half cylinder obtained by dividing a cylinder into two vertically, and a window portion 23 formed in the body portion 22. ), the hood portion 24 protruding inward at the upper end of the body portion 22 (the end on the side of the second housing 11B), and the lower side of the window portion 23 in the body portion 22. It has a stepped portion 25 protruding inward. In addition, a part corresponding to the rib dividing the side end of the window portion 23 is a locking piece 23a.

The first attachment 21A and the second attachment 21B are mounted so as to cover the circumferential surface of the body portion 42 of the alignment member 41 from both left and right sides. Then, the hooking piece 23a is hooked to the hook part 42a of the body part 42 of the aligning member 41 . The locking piece 23a is a member that has elasticity and functions as a spring and exerts a spring force, so that the locking state with the hook portion 42a is not easily released. Further, the hood portion 24 enters into the attachment engaging groove 11a1 of the second housing 11B and engages with it. Further, the stepped portion 25 engages with the first housing-side surface 42d of the body portion 42 of the alignment member 41 . In this way, the hood part 24 engages with the attachment engaging groove 11a1 of the second housing 11B, and the stepped part 25 is formed in the first part of the main body part 42 of the alignment member 41. Since it engages with the housing-side surface 42d, the state in which the alignment member 41 is attached to the second housing 11B is maintained by the first attachment 21A and the second attachment 21B. As a result, the positional relationship between the alignment member 41 and the second housing 11B is stabilized, and load is prevented from being applied to the bending member 81.

And, as shown in FIGS. 25 and 26, in each second terminal 51B, the base 52 and the locking piece 55 are accommodated in the bending member insertion cavity 44 of the alignment member 41, The contact piece 54, the side wall 56a, and the deformation preventing wall 56b are accommodated in the terminal accommodating cavity 13 of the second housing 11B. However, since the lance 15 is not formed on the wall surface of the terminal accommodating cavity 13 of the second housing 11B as described above, each second terminal 51B is formed in the insertion direction of the bending member 81. It is movable to some extent (in the vertical direction in Figs. 25 and 26). For example, in the example shown in Fig. 26, the engaging protruding piece 57 of the second terminal 51B is located in the protruding piece engaging groove 13a in the terminal accommodating cavity 13, but the bending member The protruding piece in the insertion hole 44 may be located in the engaging groove 44a. And, with respect to the insertion direction of the bending member 81, the length l2 of the protruding piece engaging groove 13a in the terminal accommodating cavity 13 is the protruding piece engaging groove in the bending member insertion cavity 44. It is preferable to set longer than the length l1 of the coupling groove 44a. In this way, when the length l2 of the protruding piece engaging groove 13a and the length l1 of the protruding piece engaging groove 44a are longer than the length L of the engaging protruding piece 57, the second terminal Since 51B is movable in the insertion direction of the bending member 81, the size of the bending member 81 and the size of the first terminal 51A in the terminal accommodating cavity 13 of the first housing 11A Even if there is a tolerance at the press-in position, this tolerance can be absorbed.

And, when the length l1 of the protruding piece engaging groove 44a in the bending member insertion cavity 44 is sufficiently long, shortening the protruding piece engaging groove 13a in the terminal accommodating cavity 13 It is also possible, and it is also possible to omit the protruding piece engaging groove 13a.

As a result of the above, the terminals 51 located at both ends of the flexible bendable member 81 such as an electric wire can be inserted into the housing 11 accurately, easily and in a short time with one alignment member 41. Connector ( 10), and an alignment member 41 used therefor.

Incidentally, the configuration and operation of the other points of the connector 10 in the present embodiment are the same as those in the first embodiment, and thus the description thereof is omitted.
