Patent ID: 7563135

Claim:
A connector, comprising: a connector housing having a terminal receiving space for receiving a metal terminal, and a retainer for preventing withdrawal of the metal terminal from the terminal receiving space; wherein said retainer includes: a lance inserted into said terminal receiving space through an opening portion formed through an outer wall of said connector housing, and retainingly engaged with said metal terminal located in a proper position within said terminal receiving space so as to prevent withdrawal of said metal terminal from said terminal receiving space; and a lance abutment portion abutting against said lance retainingly engaged with said metal terminal, and retainingly engaged with a retaining portion formed at said connector housing so as to hold said lance in retainingly-engaged relation to said metal terminal; and wherein said lance is provided such that the amount of insertion of said lance in said terminal receiving space before said lance is retainingly engaged with said metal terminal is equal to the amount of insertion of said lance in said terminal receiving space when said lance is retainingly engaged with said metal terminal; and when said metal terminal is kept half inserted in said terminal receiving space, said lance is located outwardly of said terminal receiving space, so that said lance prevents said lance abutment portion from being retainingly engaged with said retaining portion, thereby detecting the fact that said metal terminal is half inserted in said terminal receiving space.
