  • Patent number: 6872093
    Abstract: A terminal fitting (10) has a main body (11) and stabilizer (17) for preventing upside-down insertion stands up from a surface of the main body (11). Elongated projections (50) extend from a surface of the main body (11) opposite the stabilizer (17). If the male terminal fitting (10) is inserted upside down, the elongated projections (50) contact a bottom wall (24B) at the entrance of a cavity (24) during the insertion to shift the male terminal fitting (10) transversely. Thus, the stabilizer (17) is caught deeply by a ceiling wall (24C) at the entrance. As a result, the male terminal fitting (10) is prevented from any further insertion.

  • Patent number: 6702614
    Abstract: A connector has a housing (40) with cavities (41) and resiliently deformable locks (43) that project into the cavities (41). Terminal fittings (10) are insertable into the cavities (41) and deform the locks (43) in a deforming direction (DD) that intersects the inserting and withdrawing directions (IWD) of the terminal fitting (10). The locks (43) then restore and locking surfaces (64) of the locks (43) lock the terminal fittings (10) in the cavities (41). Each locking surface (64) has an upper locking surface (58) furthest into the cavity (41) and a lower locking surface (61). The lower locking surface (61) is at an obtuse angle to the withdrawing direction of the terminal fitting (10), whereas an angle of the upper locking surface (58) to the withdrawing direction is smaller than the angle of the lower locking surface (61).

  • Patent number: 6702627
    Abstract: A connector has a housing (1) and retainer mount hole (8) is open in the housing (1) from its bottom surface over to its opposite side surfaces. Upon being moved from a partial locking position to a full locking position, A retainer (7) can be moved from a partial locking position to a full locking position and is guided obliquely forward by guides (22-25). Thus, the retainer (7) can be constantly guided to a specified position regardless of a variation in the fitted position of the retainer (7) in the retainer mount hole (8) along forward and backward directions. Since the retainer (7) and terminal fittings (4) can constantly have a proper positional relationship, a problem of a varying function of the retainer (7) to detect the insufficiently inserted states of the terminal fittings (4) due to a variation in the fitted position of the retainer (7) can be solved.
