[0022] will now refer to Figures 1 to 7 Preferred embodiments of the present invention are described.

[0023] The connector includes a female housing 10 and a male housing 20 that fit together correctly. Another male shell (hereinafter referred to as "error shell 30") is located in the vicinity of the male shell 20, which is identical to the convex shell 20 in the shape and size of the outer edge, but the number of poles is different on the convex shell 20 . In the drawings, the opening shape of the cavity 11 in the female housing 10 , the opening shape of the cavity 21 in the male housing 20 , and the opening shape of the cavity 31 in the wrong housing 30 are schematically shown.

[0024] The female housing 10 has a fitting recess 12 that is open to its front (ie, figure 1 surface presented in). When viewed from the front side, the fitting recess 12 has a substantially rectangular shape with four arcuate rounded corners. Narrow and elongated grooves 13L and 13R having ...

Abstract

Connector. An attempt to fit an improper combination of housings (10, 30) together brings a projection (32R) of the wrong housing (30) into abutting engagement with an interference portion (15) in a fitting recess (12). Abutment surfaces (15a, 32Ra) are inclined in directions to move an inner peripheral surface of the fitting recess (12) towards an outer peripheral surface of the wrong housing (30). Therefore, the fitting recess (12) cannot deform and spread out, and the fitting of the wrong housing (30) cannot proceed by force.

Description

technical field [0001] The present invention relates to a connector with an incorrect assembly detection function. Background technique [0002] As an example of a connector in which a male housing is inserted into a fitting concave portion in a female housing, there is known a type of connector in which a plurality of male housings are prepared in which The shape of the inner edge of the recess is the same, but the number of poles is different) and a variety of convex shells, the shape of the convex shell is the same on the outer edge, but the number of poles is different, and each pair of corresponding concave and convex shells can be assembled together. In such a connector, the male housings have the same outer edge shape and the fitting recesses have the same inner edge shape, so there is a fear of fitting together an incorrect combination of the female and male housings. [0003] Therefore, heretofore, there has been a type employing a misfit preventing means in which...
