  • Patent number: 11183781
    Abstract: A connector includes a base member having a projection, a contact made of a conductive material and having a projection accommodating portion of a recess shape into which the projection is inserted, and a housing holding the contact. The housing has a holding mechanism configured to hold a flexible conductor disposed to extend across an opening end portion of the projection accommodating portion of the contact. When the projection of the base member is inserted into the projection accommodating portion of the contact together with the flexible conductor held by the holding mechanism, the flexible conductor is sandwiched between a lateral surface of the projection and an inner surface of the projection accommodating portion to contact the inner surface of the projection accommodating portion. The contact is electrically connected to the flexible conductor.
