Abstract

PURPOSE:To provide a plug by which constant tensile force elimination can be obtained even when a diameter of an electric wire is different and jointing work of half divided bodies to constitute a housing can be easily performed. CONSTITUTION:In a tensile force eliminating body 51, one end part is inserted and installed in vertical grooves 50 formed on both side walls of a recess 21a of a body 11 to constitute an electric wire pull-out port 21 so as to be freely mountable and demountable, and the other end side is projected in the recess 21a. Electric wires 31 connected to plug edges 15 are pulled outside of a housing 1 composed of the body 11 and a cover 12 through the electric wire pull-out port 21. A part of the tensile force eliminating body 51 projecting to the recess 21a from the vertical grooves 50 projects in its slant posture in the anti-pull-out direction of the electric wires 31, and hook-fastening claws 51b on the tips are elastically brought into contact with a casing of the electric wires 31. When the electric wires 31 are pulled in the pull-out direction, the hook-fastening claws 51b bite into the casing of the electric wires 31, and eliminates tensile force applied to the electric wires 31.

Since the tension removing body that regulates the movement of the wire due to the force in the drawing direction is provided on both inner walls of the wire drawing port, a constant tension removing performance can be obtained even if the diameter of the wire is different. At the time of joining, the force for pressing the electric wire in the joining direction is not required, so that the joining work can be easily performed.

Since the other end where the hooking claw to bite is formed is projected in the electric wire drawing port by inclining in the direction opposite to the drawing direction, it is possible to use a tension removing body according to the shape of the electric wire and change the housing. Without changing the tension removing body, the tension can be removed according to the shape of the electric wire.
