Abstract
Abstract An electric connector is provided with an insulator which includes a base section provided with a main face, electrically conductive contacts arranged on the main face of the base section, a coupling section accommodating the contacts, and end blocks formed on both ends of the base section. Each end block is provided with a receiving face parallel to the main face, a mounting face normal to the main face and a receiving space extending normal to the receiving face. A locking block is detachably received within the receiving space for locking engagement with a mating connector. The locking block is provided with a hook projecting from the receiving face for locking engagement with the mating connector, and the first and the second slots to be placed in engagement with a hook pin used for securing the connector to a circuit board. Alternatively, the end block may be provided with a cutaway extending in an opposite surface to the receiving face in combination with a side slot formed in the locking block for receiving an edge of the circuit board.
