  • Publication number: 20240039201
    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.

  • Publication number: 20220376432
    Abstract: The sealing element of the waterproof connector has a shape in which a family seal portion that waterproofs the peripheries of electric wires which are sandwiched between an inner housing and an outer housing 40, and which are not illustrated, and a seal ring portion that performs waterproofing between the seal ring portion and a mating housing are integrated. The standing board portions of the inner housing penetrate the long openings of the sealing element, and the portion to be caught of the outer housing is caught by catch protrusion portions that are formed in upper portions of the standing board portions and each have a hook shape, whereby the inner housing and the outer housing are assembled in a state in which the family seal portion of the sealing element is sandwiched between the inner housing and the outer housing. The mating housing comes into contact with the third waterproof portion of the sealing element, which acts as the seal ring portion.

  • Patent number: 9912089
    Abstract: An electrical connector is disclosed having a terminal housing, a female terminal, and a holding protrusion. The female terminal is positioned in the terminal housing and has a terminal body into which a complementary male terminal may be inserted and extracted. The holding protrusion projects from the terminal body in a direction orthogonal to inserting and extracting directions, and is press-fitted in the terminal receiving terminal housing.
