Abstract: There is provided a connector in which a plug is put to a socket in any rotational direction around an axis and is guided to a normal position smoothly thereby providing proper connection with a simple structure. On opposite surfaces of the plug and the socket, there are provided a tilted cam surface and a cam follower with which the plug and the socket are slidably contacted to each other, rotated and positioned in a rotational direction around the axis when the plug is fitted onto the socket axially. At the center of one of the opposite surfaces of the plug and the socket, a pin-receiving hole is formed, and a center pin at the center of the other fits into the pin-receiving hole before the tilted cam surface comes in contact with the cam follower.

Abstract: A connector is provided in which, only inserting a plug and a socket with each other, a plug body and a socket body are rotated relative to each other around a center axis line to a regular position, and the overall outer diameter of the connector can be reduced. An outward protrusion 9 is provided on an outer peripheral surface of the distal end portion of an insertion portion 7 of a plug body 4, a plurality of inward ridges 17 extending in an axial direction facing are provided on the inner surface of a cylindrical portion 8 of a socket body 6, a groove 16 through which the outward protrusion 9 can pass is formed between each of the adjacent ridges 17, and an inclined cam surface 18 is provided on the inner surface of the cylindrical portion 8 closer to the proximal end portion than the ridge 17, so that the protrusion 9 can slidably contacts and guides the plug body 4 to a regular position.

Abstract: A female contact is used in an electrical connector for a computer or electronic equipment. An elongated conductive piece of the contact is punched with a press and has narrower end portions at both ends. One narrower portion is symmetrical to the other around the center of piece. When the piece is folded on itself at the center, the overlapped narrower portions form a forked receiver suitable to receive a male contact terminal.
