Abstract
Abstract An electrical connector retains metal terminals more positively without insertion and removal problems caused by fatigue of any part of the connector mechanism. A spacer is provided with a drive control portion having a retaining release projection and a retaining fixture projection, both of which engage driven projections within the connector housing to enable provisional and complete connection of a metal terminal in the housing.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
117 words
In an electrical connector, a metal terminal retaining mechanism comprising: a connector housing having two flexible retaining pieces provided in a terminal receiving chamber so as to retain a metal terminal; and a spacer, movably connectable to said connector housing and having a provisional retaining position and a complete retaining position; said spacer being configured such that, in a provisional retaining position of said spacer, one of said flexible retaining pieces is driven to a position out of engagement with said metal terminal; and said spacer further being configured such that, in a complete retaining position of said spacer, said one of said flexible retaining pieces is driven to a position in engagement with said metal terminal.
Claim 2
Dependent Claim
117 words
In an electrical connector, a metal terminal retaining mechanism comprising: a connector housing having two flexible retaining pieces provided in a terminal receiving chamber so as to retain a metal terminal; and a spacer, movably connectable to said connector housing and having a provisional retaining position and a complete retaining position; said spacer being configured such that, in a provisional retaining position of said spacer, one of said flexible retaining pieces is driven to a position out of engagement with said metal terminal; and said spacer further being configured such that, in a complete retaining position of said spacer, said one of said flexible retaining pieces is driven to a position in engagement with said metal terminal.
Claim 3
Dependent Claim
59 words
A mechanism according to claim 1, wherein said spacer includes at least one retaining piece, and said connector housing includes at least one provisional retaining hole and one complete retaining hole, said retaining piece being fitted into said provisional retaining hole in said provisional retaining position, and being fitted into said complete retaining hole in said complete retaining position.
Claim 4
Dependent Claim
