A connector ( 1 ) includes a connector housing ( 2 ), a terminal ( 3 ) received in a terminal reception chamber ( 21 ), and a retainer ( 4 ) inserted in a retainer insertion hole ( 22 ) of the connector housing ( 2 ) and configured to shift between a terminal insertion allowable position and a terminal fit position. A terminal locking protrusion ( 47 ) of the retainer ( 4 ) has a base protrusion ( 45 ) configured to come in contact with a rear wall ( 31 b ) of an opposite terminal connection part ( 31 ) of the terminal ( 3 ) with the retainer ( 4 ) being in the terminal fit position, and a tip end protrusion ( 46 ) provided on an enter-side face of the base protrusion ( 45 ) and configured to enter space inside a connection part ( 33 ) of the terminal ( 3 ) with the retainer ( 4 ) being in the terminal fit position.
1. A connector comprising:
a connector housing having a terminal reception chamber and a retainer insertion hole opening into the terminal reception chamber;
a terminal received in a terminal reception chamber by insertion, the terminal having an opposite terminal connection part connected to an opposite terminal, an electric wire connection part connected to an electric wire, and a connection part arranged between the opposite terminal connection part and the electric wire connection part; and
a retainer inserted in the retainer insertion hole, having a terminal locking protrusion, and configured to shift between a terminal insertion allowable position and a terminal fit position,
wherein the terminal locking protrusion in the terminal insertion allowable position is arranged outside the terminal reception chamber to allow an insertion of the terminal in the terminal reception chamber,
wherein the terminal locking protrusion in the terminal fit position protrudes inside the terminal reception chamber and is locked to a rear wall of the opposite terminal connection part of the terminal to prevent a movement of the terminal in a direction opposite to an insertion direction of the terminal, and
wherein the terminal locking protrusion has
a base protrusion configured to come in contact with the rear wall of the opposite terminal connection part of the terminal with the retainer being in the terminal fit position, and
a tip end protrusion provided on an enter-side face of the base protrusion and configured to enter space inside the connection part of the terminal with the retainer being in the terminal fit position.
