に固着される。 The contact 18 has a cross shape that fits into the groove 15 and the hole 11, and has a protrusion 19 formed at one end of each of two orthogonal sides, and a tip on the opposite side to the protrusion 19. Convex portions 20 that fit into the four holes 11 of the partition wall 9 of the housing 8 are formed on the sides, and a square-shaped convex portion 21 for fitting is further formed in the center of the same surface. Therefore, if the contact 18 is fitted into the cross-shaped recessed groove 15 of the partition wall 9 of the female housing 8 with adhesive and fixed, the protrusion 21 and the recess 16 will fit together, and the protrusion 20 will connect the four The two holes 1 are closed, and only the two adjacent protrusions 19 protrude from the partition wall 9, which is the coupling surface with the male housing 1. The contacts 18 are also rotated by 90 degrees and fixed in the grooves 15 of the partition wall 9 of each male housing 8.

形状の十字状の接触子が用意される。 In this case, the cross-shaped contact 18 fixed in the groove 4 of the male housing 1 has only two adjacent protrusions 19 fixed in the groove 4 that are connected to the female housing 8. A cross-shaped contact protruding from the top surface of the female housing 8 is provided, and a cross-shaped contact 17 fixed to the groove 15 of the female housing 8 has a cross-shaped contact protruding from the top surface. A cross-shaped contact is prepared in which a recess 4' is left in the recessed groove 15 by the notches at the two ends, and the other parts are flush with the partition wall 9, which is the joining surface with the male housing 1. .

であることは直ちに判明する。 In either case shown in Figures A and B of Figure 5, the two convex portions 19 will protrude, so
When the protruding length of the protrusion 19 is set appropriately, and the two protrusions 19 on one side and the recess 4' formed by the cutout part of the contactor 17 on the other side connect both housings, If the connection of each optical fiber wire is made in the fitted state, then when all the female housings 8 are separated and rejoined, if they are connected by mistake, the convex portion 19 It is immediately obvious that the connection is erroneous because the engagement element 12 and the convex element 5 between the housings, which have already been described, do not engage with each other.

かることができる。[Effect] In the present invention, a cross-shaped concave groove is formed in one of the cross-shaped grooves formed on the top surface and the partition wall of each of the connecting surfaces of a plurality of male housings and female housings, and has two notched ends. One of the contacts is rotated by 90 degrees and secured in place, and a cross-shaped contact with two convex tips is secured to the other concave groove while being rotated by 90 degrees. The two types of contacts prepared should be rotated 90 degrees each and attached to the housing.In this point, in order to prevent the female housing from erroneously connecting to the male housing, measures to prevent erroneous connection are taken during molding of the housing. The manufacturing cost can be reduced compared to the case where the connecting means for the purpose is integrally molded.
