Connector housing
First Claim
1. A connector housing, comprising:
- at least one cavity for accommodating at least one terminal fitting, a housing main body having a hollow portion intersecting the cavity, and a retainer configured for locking in first and second partial locking positions in the hollow portion, the retainer being configured to permit insertion and withdrawal of the terminal fitting into and out of the cavity when the retainer is in the first and second partial locking positions, the retainer further being configured for insertion to a full locking position where the retainer is deeper in the hollow portion than in the first and second partial locking positions to lock the terminal fittings in the cavities, wherein the retainer and the housing main body are configured such that a force for resisting movement of the retainer from the first partial locking position to the second partial locking position is larger than a force resisting movement of the retainer from the second partial locking position to the full locking position.

Abstract
A connector housing (11) is provided to prevent a retainer (15) from inadvertently moving from a partial locking position to a full locking position. The retainer (15) can be held in a partial locking position where the retainer (15) is located at a shallow insertion position in a hollow portion (14a) and permits the insertion and withdrawal of terminal fittings (T). The retainer (15) also can be in a full locking position (P3) where the retainer (15) is deeper in the hollow portion (14a) to lock the terminal fittings (T) so as not to come out of cavities. There are first and second partial locking positions (P1 and P2) of the retainer (15) at different depths in an inserting direction. A holding force for partially locking the retainer (15) in the housing main body (12) is set larger in the first partial locking position (P1) than in the second partial locking position (P2) before the full locking position (P3).
