Abstract: A connector comprises a contact pin, a housing into which the contact pin is inserted, and a retainer. The contact pin includes a contact point portion formed on an end thereof and defining an opening adapted to receive a mating contact, and an engagement portion. The engagement portion is defined at least partially through the contact point portion, and includes a continuous opening formed partially through a side wall of the contact point portion in a height direction and partially through a top wall or a bottom wall of the contact point portion in a width direction. The retainer is insertable into the housing in a direction intersecting the direction of insertion of the contact pin. The retainer is adapted to be inserted into the housing and engage with the engagement portion of the contact pin to secure the contact pin within the housing.

Abstract: An electrical connector assembly comprises a first connector including a first housing having a mating opening, a second connector including a second housing configured to be mated with the mating opening of the first connector, and a drainage structure provided on and corresponding to a boundary portion between the first housing and the second housing. The boundary portion faces the mating opening. The drainage structure includes a convex region having a top at the boundary portion, a first concave region continuous with the convex region and formed in the first housing, and a second concave region continuous with the convex region and formed in the second housing.

Abstract: A seal member includes a main body portion, an easily-deformable portion formed integrally with the main body portion and being more easily deformable than the main body portion, and a pair of lip portions. The lip portions are formed on an outer peripheral side of the seal member in a loading direction in which a compressive load elastically deforming the seal member acts.

Abstract: An electrical connector comprises a housing having a water stop groove and a region disposed between an end of the housing and the water stop groove. The water stop groove extends along a circumferential direction of the housing orthogonal to a mating direction of the electrical connector. The water stop groove is dimensioned to allow a surface tension to act on a quantity of water accumulated in the region.

Abstract: An electrical connector assembly comprises a first connector and a second connector. The first connector has a hood defining a mating opening. The second connector has a housing body configured to be received in the hood, a rear end wall formed continuous with the housing body and projecting outward from the housing body in a circumferential direction, a lock arm configured to prevent disengagement of the first connector and the second connector, and a cover disposed at the rear end wall covering a portion of the lock arm. A front end surface of the rear end wall facing the second connector forms a uniformly continuous flat surface in a region including the cover.

Abstract: An electrical connector that prevents water from entering the hood of the electrical connector. The electrical connector includes a housing adapted to be mated in a receiving space in a hood of a mating connector. On a top side of the electrical connector in a state where the electrical connector is mated to the mating connector, the housing includes an inclined surface having an inclination angle of more than 90° at a front end of the hood of the mating connector for draining water falling onto the electrical connector.

Abstract: An electrical connector comprises a housing and a contact held by the housing. The housing has a hood including a receiving space for receiving a mating connector and a pair of first inner surfaces extending along a vertical direction. The first inner surfaces face the receiving space and are disposed at a first interval in a horizontal direction. Each of the first inner surfaces includes a first inclined surface extending a predetermined distance from a front end of the hood in a mating direction toward an opposite rear end of the hood.
