Claims

[Scope of utility model registration request]

A plug to which a cable is connected and fixed; a relay connector that has an insertion part that is removably inserted into the insertion part formed at the front end of the plug, and is electrically connected to the plug; A cylinder having a threaded portion on its circumferential surface that is threaded into a threaded portion on the outer circumferential surface of the relay connector, and which is externally fitted onto the outer circumferential surface of the plug and tightens and fixes the plug to the relay connector by the threaded engagement of the threaded portion. a coupling ring having a shape, an annular protruding wall formed on the outer circumferential surface of the plug to prevent the coupling from coming off, and an annular protruding wall that is fitted onto the outer circumferential surface of the plug so that when tightened by the coupling ring, the distal end surface of the insertion part of the relay connector and the annular protruding wall are formed on the outer circumferential surface of the plug. Equipped with an O-ring that is pressed into contact with the projecting wall,
A cylindrical wall having an L-shaped cross section is formed on the outer circumferential surface of the relay connector, and the cylindrical wall has an L-shaped cross section and fits into the front opening end of the coupling ring, and a plurality of slots are formed in the cylindrical wall along the axial direction of the cylindrical wall. A protrusion is formed around the axis, and a protrusion is formed on the outer circumferential surface of the cylindrical wall, and a groove-like part is formed in the front open end of the coupling ring into which the protrusion is inserted at a predetermined tightening position of the coupling ring. A connector device characterized in that a recess is formed along the circumferential direction and is removably engaged with the protrusion when the coupling ring rotates at a predetermined tightening position, at the end of the groove. .
