Abstract: A retainer (30) including a pair of side plates (32) is mounted such that the retainer (30) crosses over a housing (10) along width direction and the side plates (32) bulge out along width direction from side surfaces of the housing (10). Protection walls (27, 28) are formed on the side surfaces of the housing (10) to project around movable ranges of the side plates (32) of the retainer (30). Thus, inadvertent movement of the retainer (30) due to the contact of an external matter with the side plates (32) can be prevented. The protection walls (27, 28) are formed to define jig insertion holes (29). Thus, the side plates (32) of the retainer (30) can be disengaged from a full locking position by inserting a jig (J) through the jig insertion holes (29).

A reinforcement (36) bulges out on a lower surface (31) of the lock (27) toward the deformation space (S) from a phantom line (L) connecting a front bending point (31b), which is a leading end position of the lock (27) with respect to a deforming direction when the lock (27) is deformed maximally, and a deformation supporting position (31c).

Abstract: Cavity towers (14) forming front parts of cavities (11) project forward independently of each other from a back end surface (13A) of a mount space (13) formed in a housing (10) to mount a retainer (30). The cavity towers (14) are prevented from deformations by being coupled to the adjacent cavity towers (14) by couplings (26). Thus, when a pulling force acts backward on a terminal fitting (50), withdrawal of the terminal fitting (50) resulting from the deformation of the cavity tower (14) can be prevented. Therefore, the reliability of a function of locking the terminal fittings (50) can be improved.

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.

A slanted guide surface (22) is formed at the peripheral rear edge of each cavity (11) for guiding the female terminal fitting (30) into the cavity (11) and is slanted at an obtuse angle to an inserting direction of the female terminal fitting (30). A stabilizer-inserting groove (20) is formed in a surface of the cavity (11) and has an open rear end into which a stabilizer (47) of the female terminal fitting (30) is insertable. A preventing surface (27) is provided at the peripheral rear edge of the cavity (11) and abuts the stabilizer (47) when the female terminal fitting (30) is inserted in an improper posture. An angle of the preventing surface (27) to the inserting direction is less than an angle of the slanted guide surface (22).

Abstract: An electrical connector system has an electrical contact structure including an electrically conducting contact with a metallic contact body having a hollow tubular portion, and a metallic contactor extending from the contact body. A hollow nonmetallic sleeve is joined to and extends from the hollow tubular portion of the contact body. The nonmetallic sleeve is coaxial with the hollow tubular portion in a region where the hollow tubular portion and the nonmetallic sleeve are joined to each other. A wire is inserted through an interior of the nonmetallic sleeve and into the hollow tubular portion of the contact body and is crimped to the hollow tubular portion. The electrical contact structure is received in an electrical connector body.
