Abstract
Abstract The connector consists of a connector housing with a plurality of terminal accommodating chambers and a terminal locking member mounted to the rear portion of the connector housing. The terminal locking member is fitted to the connector housing in one of two engagement states--a preliminarily engaged state and a fully engaged state. The terminal locking member has resilient support pieces for fixing the terminal lugs in the terminal accommodating chambers. When the terminal locking member is moved backwardly from the preliminarily engaged state, the resilient support pieces ride on triangular engagement projections formed on the connector housing, moving outwardly out of the insertion path of the terminal lugs. This allows the terminal lug in question to be pulled out without disengaging the terminal locking member from the connector housing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
129 words
A connector with a terminal locking member comprising: a connector housing having a plurality of chambers accommodating terminal lugs therein; a terminal locking member mounted at a rear portion of said connector housing movably in two steps, said two steps including a preliminarily engaged state and a fully engaged state; resilient support pieces provided in said terminal locking member for fixing said terminal lugs in the terminal accommodating chambers; and engagement projections provided in said connector housing for holding said terminal locking member in the preliminarily engaged state; whereby when said terminal locking member is moved backwardly from the preliminarily engaged state, said resilient support pieces ride on said engagement projections, and thereby cause said resilient support pieces to move out of the insertion paths of said terminal lugs.
Claim 2
Dependent Claim
129 words
A connector with a terminal locking member comprising: a connector housing having a plurality of chambers accommodating terminal lugs therein; a terminal locking member mounted at a rear portion of said connector housing movably in two steps, said two steps including a preliminarily engaged state and a fully engaged state; resilient support pieces provided in said terminal locking member for fixing said terminal lugs in the terminal accommodating chambers; and engagement projections provided in said connector housing for holding said terminal locking member in the preliminarily engaged state; whereby when said terminal locking member is moved backwardly from the preliminarily engaged state, said resilient support pieces ride on said engagement projections, and thereby cause said resilient support pieces to move out of the insertion paths of said terminal lugs.
Claim 3
Dependent Claim
21 words
A connector as claimed in claim 1, wherein said resilient support pieces have step portions adapted to engage said engagement projections.
Claim 4
Dependent Claim
22 words
A connector as claimed in claim 2, wherein said resilient support pieces have terminal locking projections adapted to lock said terminal lugs.
Claim 5
Dependent Claim
19 words
A connector as claimed in claim 3, wherein said terminal locking projections are located forwardly of said step portions.
Claim 6
Dependent Claim
65 words
A connector as claimed in claim 1, wherein said terminal locking member has an engagement piece and said connector housing has a pullout prevention projection adapted to engage said engagement piece of the terminal locking member when said terminal locking member is moved backwardly from the preliminarily engaged state so as to prevent said terminal locking member from being pulled out from said connector housing.
Claim 7
Dependent Claim
30 words
A connector as claimed in claims 1, wherein said engagement projections are in a triangular configuration having forwardly and rearwardly inclined surfaces, whereby said resilient support pieces may ride thereon.
