Claims

[Scope of utility model registration request]

A cylindrical joint body attached to the outer periphery of the connecting pipe, a push ring that tightens and fixes the pipe via a pipe tightening mechanism by screwing onto the end of the joint body, and a space between the push ring and the joint body. A pipe joint equipped with a biting ring which is interposed and electrically connects the press ring, the joint main body, and the connecting pipe,
The biting link is made of a highly conductive metal having a spring action, and biting claws are integrally molded at a plurality of circumferential parts of the biting ring, each having a back surface bent so as to face each other and an engaging part, The angle between the back surface part and the central axis of the connecting pipe is set to be larger than the angle that the press ring taper part makes with the central axis of the connecting pipe, and the angle that the meshing part makes with the central axis of the connecting pipe from the connecting pipe pulling side is set to be an obtuse angle. The biting pawl is pressed from the main body side by screwing into the press ring, the back surface is pressed into contact with the taper part of the press ring, and the engaging part bites into the outer circumferential surface of the connecting pipe. Electrically conductive pipe fittings.
