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.

Dependent claims

An electric connector for mounting on a circuit board, said electric connector comprising:

an insulator (21) comprising a central base section (21b) with a main face (21a), a coupling section (21c) formed on the main face of said base section for coupling with a mating connector (8), and a pair of end blocks (24) formed on opposite ends of said base section, each of said end blocks having a receiving face (24a) extending n parallel to the main face, a mounting face (24b) substantially perpendicular to the main face, and a receiving space (25) extending substantially perpendicular to said receiving face and parallel to said coupling section;
a plurality of conductive contacts (22) mounted in said coupling section of said insulator;
a pair of locking blocks (23) received in said receiving spaces in said end blocks of said insulator, each of said locking blocks having a hook (26) projecting from said receiving face for making a locking engagement with said mating connector, each of said locking blocks having first and second hook pin retainer slots (23a, 23b) respectively formed in opposite surfaces thereof and in parallel with said mounting face for engagement with a hook pin (29) to lock said connector to said circuit board;
and
means (27) for detachably engaging each of said locking blocks and each of said end blocks with each other for keeping each locking block in the receiving space in each end block.
