Abstract
Abstract Disclosed herein is a connector which comprises a female housing and a male housing to be inserted and fitted into the female housing for establishing an electrical connection therebetween. The connector further comprises locking member pivotably provided on one of the female and male housings in such a manner that one housing is locked with the other housing by the locking member only when the female and male housings are properly fitted together. The locking member includes engagement projection for temporarily hooking the locking member to one housing until the other housing is inserted into one housing. On the other housing, there is provided a projection for disengaging the lock member from one housing when one housing is inserted into the other housing.

Claim 1
Independent Claim
121 words
A connector, comprising: a female housing; a male housing inserted and fitted into said female housing for establishing an electrical connection therebetween; lock means pivotably provided on one of said female and male housings in such a manner that said one housing is locked with the other housing by said lock means only when said female and male housings are properly fitted together; means for temporarily hooking said locking means to the one housing until the other housing is inserted into said one housing, said hooking means provided on said lock means; and means for disengaging said lock means from said one housing while the other housing is inserted into said one housing, said disengaging means provided on the other housing.
Claim 2
Dependent Claim
121 words
A connector, comprising: a female housing; a male housing inserted and fitted into said female housing for establishing an electrical connection therebetween; lock means pivotably provided on one of said female and male housings in such a manner that said one housing is locked with the other housing by said lock means only when said female and male housings are properly fitted together; means for temporarily hooking said locking means to the one housing until the other housing is inserted into said one housing, said hooking means provided on said lock means; and means for disengaging said lock means from said one housing while the other housing is inserted into said one housing, said disengaging means provided on the other housing.
Claim 3
Dependent Claim
23 words
A connector as claimed in claim 1, wherein said one housing is said female housing and the other housing is said male housing.
Claim 4
Dependent Claim
89 words
A connector as claimed in claim 2, wherein said female housing has a fitting space into which said male housing is inserted and an upper surface with a slit opening to the fitting space, and said locking means includes a locking member pivotably provided on said female housing by hinge means, and said locking member has at least one locking portion which protrudes into said fitting space through the slit so as to lock with said male housing when said male housing is perfectly fitted to said female housing.
Claim 5
Dependent Claim
77 words
A connector as claimed in claim 2 wherein said female housing has a concave portion formed on the upper surface thereof, and said locking member is constructed in such a manner that said locking member is pivotable between a first position in which said locking member is accommodated in said concave portion and a second position in which said locking member is rotated with a small angle with respect to the upper surface of said female housing.
Claim 6
Dependent Claim
43 words
A connector as claimed in claim 4, wherein said hooking means comprises an engagement projection formed on said locking member in such a manner that said projection is temporarily hooked with said female housing when said locking member is in the first position.
