Abstract
Abstract Male and female connectors of an extremely small size, while having a number of connection terminals, are provided. The male connector consists of a cylindrical cable-supporting member, a cylindrical conductive-wire guide member, and a core member for coupling the two with each other. The conductive-wire guide member has partitions and holding sections. The conductive wire of the cable passing through the cable-supporting member is folded on the holding section from outside to inside so that the exposed portion of the conductive wire forms a connection terminal of the male connector. The female connector consists of a casing having an insertion hole to be inserted by the male connector, a locking member for locking the male connector, projected from the end of the casing, and female side connection terminals, each to be fitted to a terminal retaining section of the casing so that the leading end thereof is exposed in the insertion hole. Since the conductive wire of the cable connected to the male connector defines the connection terminal of the male connector, the small-sized multi-terminal type male connector is realized. The female connector to be mated thereto also can be miniaturized.
