Abstract: A retainer is inserted and fitted into an engagement hole that is open in a first direction of a housing where the first direction, a second direction, and a third direction are defined as mutually-orthogonal three directions. An engagement portion is disposed at each of a pair of inner wall surfaces facing each other in the second direction in an inner peripheral wall of the engagement hole. The retainer includes a pair of first outer surfaces facing each other in the first direction, a pair of second outer surfaces facing each other in the second direction, and a pair of third outer surfaces facing each other in the third direction. A long hole passing through the third outer surface in the third direction is formed so as to be adjacent to each of the second outer surfaces, and extends in the first direction defined as a longitudinal direction. A beam portion supported at both ends by a pair of longitudinal-direction end portions is formed between the long hole and the second outer surface.

Abstract: An electrical connection structure comprises a base member, a connector, and a mating connector. The electrical connection structure comprises a half-fitting detecting mechanism including a half-fitting detecting portion in the connector and a short-circuiting member in the mating connector. The half-fitting detecting portion includes a conductive member and an inspecting member. The half-fitting detecting portion allows a half-fitting state to be detected by the short-circuiting member being in non-contact with the inspecting member when in the half-fitting state. The inspecting member short-circuits with the conductive member via the short-circuiting member by the mating engaging portion of the short-circuiting member being engaged with the engaging portion of the connector and being in contact with a contact part of the inspecting member and the short-circuiting member being in contact with the conductive member when in a normal fitting state.

Abstract: An electrical connection device includes a pair of connectors, namely a first connector and a second connector. The first connector includes a housing main body portion, a lock arm, and a cantilever portion. The second connector includes a lock receiving portion and an abutting portion. When the pair of connectors are in the unfitted state, the cantilever portion is located between the housing main body portion and the lock arm so as to be capable of supporting the lock arm. The abutting portion comes into contact with the cantilever portion when the pair of connectors are fitted together, and therefore the cantilever portion undergoes elastic displacement to a position that allows the lock arm to flex toward the housing main body portion.
