The connector body 2 has a configuration in which a plurality of contacts 6 crimped and fixed to the respective tips of a plurality of lead wires 5 drawn out from the end of the cable 4 are aligned and fixed in a housing 7. ..

As shown in FIGS. 3 (A) and 3 (B), the contactor 6 has a structure in which the contactor portion 6a and the crimp terminal portion 6b are integrated, and a flange 6c is provided therebetween.

The housing 7 is a resin molded product, and as shown in FIGS. 4 (A) to 4 (D) and FIG. 5, the housing 7 is rotatable about a main body portion 7a and thin hinge portions 7b and 7c. It is composed of a pair of lids 7d and 7e.

The main body portion 7a includes an enclosing portion 7f having a substantially trapezoidal band shape, cylindrical portions 7g and 7h arranged in two rows in the enclosing portion 7f, left and right side wall portions 7i and 7j protruding rearward, It is composed of a base portion 7k that projects rearward from the position between the cylindrical portions 7g and 7h and that horizontally extends between the side wall portions 7i and 7j.

The lid portion 7d has a contactor locking portion 7l, a fence portion 7m for preventing the lead wire from protruding, claw portions 7h and 7o on the left and right side surfaces, and a pair of claw portions 7p and 7q on the outer side. Similar to the lid 7d, the other lid 7d also has a contact locking portion 7r, a fence 7s, claws 7t and 7u, and claws 7v and 7w. The lids 7d and 7e are rotatable in the directions of arrows A and B with bending of the hinges 7b and 7c, respectively.

As shown in FIGS. 1 and 6, the contactor 6 is housed in a cylindrical portion 7g in the upper row, and the flange 6c is provided with an end surface 7g _-1 near the rear end of the cylindrical portion 7g and a locking portion. It is locked so as to be sandwiched by 7l, its upper position is regulated in the longitudinal direction, and it is fixed in a state where it does not come out from the cylindrical portion 7g. As shown in FIG. 7, the locking portion 7l extends to a position where the center line CL of the contact 6 exceeds the dimension a 1, and the area for pressing the flange 6c (indicated by cross hatching in the figure) is wide. ing. Therefore, compared with the case where the locking portion is fastened to the center line CL of the contactor 6, the pressing area becomes wider and the contactor 6 is firmly fixed.

The lead wire 5 following the contact 6 is housed in the housing 7 in a state of being bent by being in contact with the fence portion 7m, and the protrusion to the rear is restricted.

The contacts 6 housed in the lower row of cylinders 7 n and the lead wires 5 following this are also fixed in the same manner as described above and are housed in the housing 7.

As shown in FIG. 8, the contactor 6 is inserted into a predetermined tubular portion 7g from the rear side as shown by an arrow C when the lid portion 7d is open, and the Insert it to the final position shown by the dotted line, then rotate the lid 7d in the direction of arrow A to close it, and lock it in the closed position by engaging the claws 7n and 7o with the recesses 7i _-1 and 7j _-1. By doing so, as shown in FIG. 6, it is fixed in the housing 7. The other lid 7e is locked at the closed position by engaging the claws 7t and 7u with the recesses 7i _-2 and 7j _-2 , respectively.

As shown in FIG. 9, even when the contactor 6 is not completely inserted into the cylindrical portion 7g, the locking portion 7l of the lid portion 7d is not locked during the operation of closing the lid portion 7d. The locking portion 7l pushes in the direction of arrow D in contact with the flange 6c, and the closing operation of the lid portion 7d thereafter causes the contactor 6 to be inserted into the cylindrical portion 7g. Therefore, even if the contactor 6 is not completely inserted, the contactor 6 is pushed to a predetermined position and normally fixed. Here, since the locking portion 7l is defined as shown in FIG. 7, even when the insufficient insertion dimension b of the contactor 6 is comparatively large, the contactor 6 can be pushed in by the locking portion 7l. Next, it is a good city.

As shown in FIGS. 1, 6 and 10, a clamp metal fitting 8 is crimped and fixed to the end portion of the cable 4. As shown in FIG. 10, the clamp metal fitting 8 is crimped so that its rear side portion has a substantially oval shape.

As shown in FIG. 6, the cover 3 is moved in the direction of arrow E from the rear side with respect to the connector body 2 having a substantially rectangular parallelepiped shape with the lids 7d and 7e closed, so that the cover 3 is closed. It is attached so that it covers.

As shown in FIGS. 11A to 11C, 12 and 13, the cover 3 has a rectangular frame-shaped main body portion 3a and a rear cable lead-out portion 3b.

On the upper surface of the main body portion 3a, holes 3c and 3d that engage with the claw portions 7p and 7q and grooves 3e and 3f that guide the claw portions 7p and 7q, and on the lower surface, engage the claw portions 7v and 7w. Holes 3g and 3h are formed, and grooves 3i and 3j for guiding the claw portions 7v and 7w are formed.

As shown in FIG. 2A, in the cover 3 and the connector body 2, the claw portions 7p and 7q are engaged with the holes 3c and 3d, respectively, and the claw portions 7v and 7w are respectively into the hole 3g. , 3h are engaged and coupled.

Here, the dimension between the claws 7p and 7q, the holes 3c and 3d, the grooves 3e and 3f is set to X ₁ , respectively, and the dimension between the claws 7v and 7w, the holes 3g and 3h, and the grooves 3i and 3j is respectively measured. It is defined as X ₂ (≠ X ₁ ). Since X ₁ ≠ X ₂ , the connector body 2 and the cover 3 can be connected only when they have a predetermined orientation relationship, and when they have an incorrect orientation relationship, the claw portion 7p, 7q, 7v, 7w come into contact with the end face of the inlet portion of the cover 3 to restrict further joining work. Therefore, the connected connector body 2 and cover 3 are always in the normal orientation.

Further, the lids 7d and 7e are covered with the cover 3, which never opens, and the connector 1 is more reliable than the structure without the cover.

As shown in FIGS. 11 (A) to 11 (C), FIG. 12 and FIG. 13, the cable lead-out portion 3b includes a clamp metal fitting housing portion 3k, which is a rectangular space, and a trumpet-shaped lead-out port 3l. Has been formed.

As shown in FIGS. 1 and 10, the clamp metal fitting 8 is housed in the housing portion 3k, and the cable 4 is pulled out rearward through the lead-out portion 3b.

The rear end of the clamp metal fitting 8 is in contact with the end surface 3k ₋₁ of the housing portion 3k. Therefore, even when the cable 4 in FIG. 1 is strongly pulled in the direction of the arrow F, this force F is received by the clamp metal fitting 8 locked to the end face 3k ₋₁ and is not transmitted any further. ..

Further, as shown in FIG. 10, the clamp metal fitting 8 is located in the diagonal direction of the rectangular accommodating portion 3k and is restricted from rotating in the arrow G direction. Therefore, even when the cable 4 is twisted as shown by the arrow H in FIG. 1, this twisting force is received by the clamp metal fitting 8 and is not transmitted further.

Therefore, when the cable 4 is pulled or twisted, no force acts on the connection portion between the lead wire 5 and the contact 6, and the connection portion is completely protected and the connection is completed. Accidents that disconnect at some parts are reliably prevented.

Further, the lead wire 5 is bent so as to have a margin, and even if the distance between the cable 4 and the contact 6 becomes long for some reason, the change in this distance is absorbed and the connection portion is absorbed. The force does not act on.

Further, the circular other end of the clamp metal fitting 8 is in contact with the rear surface of the connector body 2, and displacement in the direction opposite to the arrow F direction is restricted.

Further, since the inner surface of the outlet port 3l has a trumpet shape, even when the connector 1 and the cable 4 are bent, the cable 4 is attached to the inner surface of the outlet port 3l as shown by the chain double-dashed line in FIG. The cable 4 is bent gently along the line so that the damage to the cable 4 is minimized.

The connector 1 having the above configuration is connected to the socket 10 shown by the chain double-dashed line in FIG. The contact pin 11 of the socket 10 relatively enters into the cylindrical portions 7g and 7h and comes into contact with the contactor 6.
