摘要： A connector includes a female-side connector and a male-side connector including an inner engagement portion and an outer engagement member or portion. The outer engagement member or portion has: an outer engagement member or portion body covering the female-side engagement portion from outside when the male-side connector is inserted into the female-side connector; and has a holder that, when the male-side connector is inserted into the female-side connector, covers the screw thread on the female-side engagement portion from outside, and fills a gap between the female-side engagement portion and the outer engagement member or portion body. The holder is disposed on an end portion side of the male-side connector from the inner engagement portion in a longitudinal direction of the male-side connector, and disposed so as to pinch the female-side engagement portion in cooperation with the inner engagement portion when the male-side connector is inserted into the female-side connector.

摘要： The present invention addresses the problem of significantly reducing torque between a cable and a connector, preventing breakage/damage to the cable, and thus increasing the durability and safety of the cable relative to the prior art when an end part of a cable is grasped and subjected to a bending or twisting action. The cable according to the present invention is provided with a cable body, a connector part attached to an end part of the cable body in the longitudinal direction thereof, and a cable holding device (strain relief) for covering a peripheral surface of the cable body, the cable holding device being provided so as to be able to rotate about the central axis of the cable body in relation to the cable body. When an operator grasps the cable holding device or a portion thereof and connects the connector part to a testing device, etc., even when torsion occurs in the cable, since the cable body side to which the connector part is attached can freely rotate along with the torsion of the cable in relation to the cable holding device, which is grasped by the operator and restricted from moving, the connector attachment portion of the cable is not prone to undergo stress.
