Abstract
Abstract The present invention is structured for preventing a spacer from being dislocated as inserting a terminal to a terminal compartment provided in a terminal connector housing, so that simple and reliable assembly and connection of the connector are made possible, and incomplete insertion of the terminal can be detected at the same time. This in turn improves the efficiency of the work, reduces the load of a worker and also improves the quality of the connector.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
156 words
A terminal connector retaining construction comprising: a connector housing, a plural number of terminal compartments provided in said connector housing, a resilient arm and a locking step provided in inner walls of each of said compartment for retaining an inserted terminal, said resilient arm and said locking step being adapted respectively to be pressed against one side of said terminal and to be engaged with the other side of said terminal, a spacer for pressing sid resilient arm against said terminal, said spacer being adapted to be inserted into said connector housing in the direction opposite to a terminal insertion direction, a provisional locking projection and a final locking projection provided on one of the outer wall of said terminal compartment and on said spacer, and engagement portions formed on one of the other member of said wall portion and of said spacer for engaging with said provisional locking projection and said final locking projection respectively.
Claim 2
Dependent Claim
156 words
A terminal connector retaining construction comprising: a connector housing, a plural number of terminal compartments provided in said connector housing, a resilient arm and a locking step provided in inner walls of each of said compartment for retaining an inserted terminal, said resilient arm and said locking step being adapted respectively to be pressed against one side of said terminal and to be engaged with the other side of said terminal, a spacer for pressing sid resilient arm against said terminal, said spacer being adapted to be inserted into said connector housing in the direction opposite to a terminal insertion direction, a provisional locking projection and a final locking projection provided on one of the outer wall of said terminal compartment and on said spacer, and engagement portions formed on one of the other member of said wall portion and of said spacer for engaging with said provisional locking projection and said final locking projection respectively.
Claim 3
Dependent Claim
44 words
A connector terminal retaining construction as claimed in claim 1, wherein said terminal is formed with projections and said spacer is formed with abutting portions which abut against said projections of said terminal when said terminal is not completely engaged with said locking step.
Claim 4
Dependent Claim
44 words
A terminal connector retaining construction as claimed in claim 1, wherein said engagement portion to be locked with said provisional projection is constructed in such a manner that said engagement portion does not interfere with said final locking projection when said spacer is inserted.
Claim 5
Dependent Claim
49 words
A terminal connector retaining construction as claimed in claim 3, wherein the interval between said provisional and final locking projections are provided in such a manner that even when said spacer is fully inserted into said terminal compartment, there remains still some distance for completing the final locking operation.
