Abstract
A retainer (30) has a penetration prevention portion (37) rearward from a locking projection (36) and configured to project into a cavity (22) when the retainer (30) is at a main locking position. A terminal fitting (10) erroneously inserted into a rear portion of the cavity (22) when the retainer (30) is at the main locking position will strike the penetration prevention portion (37) before striking the locking projection (36). Thus the erroneously inserted terminal fitting (10) cannot push the locking projection (36) in a way that could return the retainer (30) to a temporary locking position.
Claims12
A connector (1) comprising:
- a housing (20) with at least one cavity (22) for receiving at least one terminal fitting (10);
- and
- a retainer (30) insertable into said housing (20) from one side surface of the housing (20) in a direction crossing said cavity (22),
- said retainer (30) having an engaging projection (36) capable of engaging said terminal fitting (10) for locking said terminal fitting (10) in the cavity (22);
- said retainer (30) being movable between a temporary locking position where said engaging projection (36) is disposed alongside said cavity (22) and allows said terminal fitting (10) to be inserted into said cavity (22) and removed therefrom and a main locking position where said engaging projection (36) projects in said cavity (22) and engages said terminal fitting (10);
- and
- said retainer (30) having a penetration prevention portion (37) that projects into said cavity (22) and prevents said terminal fitting (10) from penetrating into said cavity (22) when said retainer (30) is held at said main locking position.
A connector (1), comprising:
- a housing (20) having opposite front and rear ends and a plurality of cavities (22) extending between the ends, a retainer insertion opening (25) extending into a side surface of the housing (20) and intersecting the cavities (22);
- a plurality of terminal fittings (10) disposed respectively in a plurality of the cavities (22), the terminal fittings (10) being fewer in number than the cavities (22) so that at least one of said cavities (22) has no terminal fitting (10) therein;
- and
- a retainer (30) disposed in said retainer insertion opening (25) and being movable between a temporary locking position and a main locking position, the retainer (30) having a plurality of engaging projections (36) corresponding to the respective cavities (22) and a plurality of penetration prevention portions (37) disposed between the engaging projections (36) and the rear end of the housing (20), the engaging projections (36) and the penetration prevention portions (37) being substantially alongside the respective cavities (22) when the retainer is in the temporary locking position and projecting into the respective cavities (22) when the retainer (30) is in the main locking position.
