  • Patent number: 10700473
    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.

  • Patent number: 10581198
    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.
