Abstract: A receptacle assembly includes a casing having a closed side and an open side, at least one receptacle hole module defined in the casing, and containing a plurality of insertion holes defined in the closed side of the casing, a plurality of extension columns each extending from the closed side of the casing, and each containing a receiving channel therein aligning with one of the corresponding insertion holes, each of the extension columns including a positioning block formed in the wall of the receiving channel, and a plurality of conductive terminals each received in the receiving channel of one of the corresponding extension columns and each abutting the positioning block such that each of the conductive terminals is fixed in the receiving channel by the positioning block.

Abstract: A power connector comprises a plug mechanism and a socket mechanism. The plug mechanism is provided with a plurality of insulating tubes designed to enclose and arranged to be spaced around respective pinning mechanism. The socket mechanism of the connector is provided with corresponding holes for the tubes, tubular conductors for the pinning mechanism, and a housing element for partially receiving the plug mechanism, whereby when the pinning means are inserted into the holes, sparks, in case there are, will be kept apart from a person' hand by both the insulating tubes and the housing element.
