A connector is provided which includes a housing in which a terminal is accommodated, and a retainer which is mounted on the housing to prevent movement of the terminal in the direction of detachment. A retainer insertion hole is provided on the housing to insert the retainer, and a provisional locking projection and a final locking projection are provided which extend into the retainer insertion hole. A guide portion is provided in the retainer which is flexibly deformed by interference from the provisional locking projection and the final locking projection, and a locked portion is formed, which is a locking hole opened in the guide portion. The locked portion and the provisional locking projection are temporarily locked during the insertion process, and the locked portion and the final locking projection are locked at the end of the insertion process.
1. A connector comprising:
a housing in which a terminal is accommodated, and
a retainer which is mounted on the housing to prevent the terminal from moving in the direction of detachment,
wherein a retainer insertion hole through which the retainer is inserted along an insertion direction, and a provisional locking projection and a final locking projection which project into the retainer insertion hole are provided in the housing,
wherein the retainer includes a bending deformation portion which bends and deforms by interference with each of the provisional locking projection and the final locking projection, and a locked portion is provided in the bending deformation portion,
wherein the locked portion and the provisional locking projection are locked together to be brought into a provisional locking state in an intermediate insertion position of the retainer into the retainer insertion hole, and the locked portion and the final locking projection are locked together to be brought into a final locking state in an insertion completion position of the retainer into the retainer insertion hole, and wherein
wherein the locked portion is formed as a locking hole opened in the bending deformation portion.
2. The connector according to claim 1 ,
wherein the bending deformation portion is a guide portion provided continuously to a retainer main body.
3. The connector according to claim 2 ,
wherein in the guide portion, a beam portion surrounding the locking hole is formed thinner than the rest of the guide portion.
4. The connector according to claim 1 , wherein the bending deformation portion is a pair of guide portions provided continuously to a retainer main body.
5. The connector according to claim 1 , wherein the provisional locking projection and the final locking projection are successively provided along the insertion direction of the retainer.
