  • Patent number: 8282423
    Abstract: A connector whose terminal portions of contacts can be reliably inserted into through holes of a circuit board. The connector comprises a housing, contacts, and an alignment member. Each contact includes a holding portion held by the housing, a terminal portion inserted into a circuit board, and a linking portion connecting the holding and terminal portions. The alignment member is mounted on the contacts and positions the terminal portions. The contacts are arranged in a longitudinal direction of the connector, and in two rows in a vertical direction thereof. Each pair of adjacent contacts in the longitudinal direction are connected by a connecting portion, to form first and second combination contacts. The alignment member has receiving portions receiving the linking portions, open portions from which the connecting portions are exposed, and grooves preventing a relative movement of the connecting portions in the vertical direction.
    Type: Grant

  • Patent number: 7658640
    Abstract: A cable connector 1 includes a cover insulator adapted to clamp a cable. The cable has an end portion bent by a bending angle ?. The cover insulator is coupled to a base insulator. The base insulator holds a terminal having an end portion bent by a bending angle ?. Herein, the angles ? and ? satisfy the relationship given by ?<??? (rad) so that the end portion of the cable is pressed by the end portion of the terminal.
