タ。 A retainer 2 is provided on the terminal insertion side of the connector housing 21, which has a lance 33 that engages the terminal 30 in the terminal accommodating chamber 22 into which the terminal 30 is inserted.
5 is movably attached along the insertion direction, and the first stage engaging portion 2 temporarily engages with both at the first stage position.
8, and a second-stage engaging portion 29 with which the retainer 25 is engaged when the retainer 25 is pushed from the first-stage position to the second-stage position. The retainer 25 is provided with protruding pieces 27, 27' that protrude in the direction, and when the retainer 25 is located at the first stage position, the terminal 30 is accommodated in the terminal accommodating chamber 22, and then the retainer is removed. 25 into the second stage position to engage the second stage engaging portion 29 so that the missing ends of the protruding pieces 27, 27' engage with the rear ends of the terminals 30, and The lance 33 is provided with an engaging protrusion 34 extending laterally, and the retainer 2
5 to the first stage position, insert the jig 36 into the terminal accommodating chamber 22 from the insertion end of the mating terminal of the connector housing 21,
Pressing the front end of the lance 33
When the engagement between the terminal 30 and the terminal 30 is released, the engagement protrusion 34 presses the protruding pieces 27, 27' to release the engagement between the protruding pieces 27, 27' and the terminal 30. An electrical connector characterized by:
