Abstract
Abstract A connector fitting construction in which a half-fitted condition is positively prevented when fitting a pair of male and female connectors together, and the fitting operation and a fitting release operation can be effected easily, and a connector housing can be formed into a small size. In this connector fitting construction, the male connector includes a connector housing, and an exclusive-use housing forming a slider receiving portion for receiving a slider therein. Guide grooves for respectively guiding opposite side portions of a body of the slider are formed respectively in opposite side portions of the exclusive-use housing. A lock arm, provided at a central portion of the exclusive-use housing, includes a lock beak having a slanting surface, and a housing lock formed on a lower surface thereof at a front end thereof, and side spaces are provided respectively on opposite sides of the lock arm. The slider has a slider arm provided in the slider body, the slider arm having a pair of abutment projections. The female connector includes a pair of stopper projections, which are formed on a housing, and abut respectively against the abutment projections when the two connectors are fitted together, a slanting projection having a slanting surface, and an engagement groove.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
184 words
A connector fitting construction comprising: a first connector including a housing having a terminal receiving chamber for receiving a first terminal; and a second connector fittable to the first connector, the second connector including: a housing including a first portion having a terminal receiving chamber for receiving a second terminal matable with the first terminal, and a second portion having a lock arm and side spaces disposed respectively on opposite sides of said lock arm; a spring member mounted in the second portion, wherein a half-fitted condition of the two connectors is prevented by a spring force of said spring member; and a slide lock member which is slidably supported in the second portion, and cooperates with said spring member so that said lock arm retains the housing of the first connector when the first and second connectors are fitted to each other, the slide lock member including an elastic arm having abutment projections formed respectively on opposite side portions of a lower surface of the elastic arm, the abutment projections which can be disposed respectively in the side spaces of the second portion.
Claim 2
Dependent Claim
