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. An engagement projection that engages with the engagement portion is formed at an intermediate portion in the longitudinal direction of the beam portion. A stress relaxation structure that relaxes stress acting on the intermediate portion of the beam portion includes a hole expanding portion that expands at least one of the pair of longitudinal-direction end portions of the long hole in a lateral direction.

Connector

In an electrical connector, a female housing is made to mate with a male housing. The female housing has guide ways each formed perpendicularly to a direction of mating of the male housing with the female housing. In the guide ways, a latch metal is disposed. The guide ways of the female housing respectively have opening portions from each of which the corresponding latch part of the latch metal is capable of projecting toward the male housing. When the male housing is inserted into the female housing, the latch parts are respectively projected from the opening portions of the female housing toward the male housing. The latch parts are respectively locked at predetermined inclined planes a formed on the male housing.

The present invention provides a connector capable of being simply and easily connected without loss of electrical continuity even in a harsh environment. First joining terminalsandare supported by a female housing, and second joining terminalsandelectrically connected to the first joining terminalsandare supported by a male housing. The male housingis inserted to mate with the female housing, which performs electrical connection. Further, slit ribstoare formed in the direction of mating in the female housing, and slitstoalong the direction of mating are formed in the male housing. The slit ribstohave recessed tapered shapes formed at a predetermined rate of angular change and a predetermined rate of width change, and the slitstohave tapered shapes having a rate of angular change and a rate of width change which are respectively greater than the predetermined rate of angular change and the predetermined rate of width change of the slit ribs.
