Abstract
Abstract A connector housing has a locking mechanism. The locking mechanism has a plate-like movable locking member provided through a thin hinge formed closer to the front of the connector housing. The movable locking member has a locking pawl at its free end and a locking portion which is formed in its inner surface and adapted to engage with a locking projection formed on a terminal. The locking pawl is adapted to engage, for locking, with a shoulder formed at the rear end of the connector housing.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
131 words
A connector housing adapted to contain a terminal attached to a conductor, said connector housing being defined by a pair of spaced apart sidewalls defining a cavity adapted to receive the terminal, an opening formed in a top wall bridging said sidewalls and juxtaposed to said cavity, a locking member integrally connected to said top wall by a thin hinge portion and pivotal between an opened position and a closed position in which said locking member closes said top wall opening, a bridging member extending between said sidewalls at an end of said opening spaced from said thin hinge for reinforcing said connector housing, and interlocking means on said bridging member and the cantilevered end of said locking member adapted to engage and retain said locking member in its closed position.
Claim 2
Dependent Claim
131 words
A connector housing adapted to contain a terminal attached to a conductor, said connector housing being defined by a pair of spaced apart sidewalls defining a cavity adapted to receive the terminal, an opening formed in a top wall bridging said sidewalls and juxtaposed to said cavity, a locking member integrally connected to said top wall by a thin hinge portion and pivotal between an opened position and a closed position in which said locking member closes said top wall opening, a bridging member extending between said sidewalls at an end of said opening spaced from said thin hinge for reinforcing said connector housing, and interlocking means on said bridging member and the cantilevered end of said locking member adapted to engage and retain said locking member in its closed position.
Claim 3
Dependent Claim
39 words
A connector housing as described in claim 1 wherein the thin hinge portion is resilient and the locking member assumes an angle less than 90° relative to the connector housing when the locking member is in its open position.
Claim 4
Dependent Claim
26 words
A connector housing as described in claim 2, wherein the locking member assumes an angle about 45° when the locking member is in its open position.
Claim 5
Dependent Claim
35 words
A connector housing as described in claim 1 wherein the terminal has a locking projection engaged by a locking projection formed on the locking member for retaining the terminal in position within said connector housing.
Claim 6
Dependent Claim
46 words
A connector housing as described in claim 4 wherein the interlocking means of the locking member and the bridging members have portions that are inclined relative to a direction normal to the direction of engagement of the terminal locking projection and said locking member locking projection.
Claim 7
Dependent Claim
29 words
A connector housing as described in claim 5 wherein the interlocking means further include second portions angularly disposed to the first mentioned portions and parallel to the normal direction.
Claim 8
Dependent Claim
41 words
A connector housing as described in claim 4 wherein the connector housing is provided with a second locking portion spaced from the locking portion of the locking member and cooperable with the terminal for retaining the terminal within said connector housing.
Claim 9
Dependent Claim
42 words
A connector housing as described in claim 7 wherein the terminal has a connector portion adapted to be detachably connected to an associated terminal for forming an electrical and mechanical connection therebetween, said terminal locking projection being spaced from said connector portion.
Claim 10
Dependent Claim
46 words
A connector housing as described in claim 7 wherein the interlocking means of the locking member and the bridging member have portions that are inclined relative to a direction normal to the direction of engagement of the terminal locking projection and said locking member locking projection.
Claim 11
Dependent Claim
29 words
A connector housing as described in claim 9 wherein the interlocking means further include second portions angularly disposed to the first mentioned portion and parallel to the normal direction.
