Abstract

An electric wire connecting device for connecting an electric wire or TV antenna feeder wire to a receptacle or terminals only by the tightening action of the device which passes a blade provided within the connecting device through the insulation cover layer so as to be contacted directly with the conductive wire core made normally of copper wire, so that electrical connection can be obtained. The invention is comprised of: basic body (1) and blade (1a) standing erect from the body, a pair of pressing pieces (1b) bent inwardly at both end edge portions, a pair of anti-motion pieces (1c) bent inwardly at both end edge portions and diverging from said pressing pieces with a predetermined cut out portion therebetween, and a stopper coupling groove (1d) defined by a cutout at a central portion of the rear edge of the body for coupling with a mating protrusion so as not to rotate with screwing of the tightening screw.

Dependent claims

An electric wire connecting device, comprising:

a conductive connecting member providing a washer function for a terminal screw in connecting electrically the electric wire;
a first blade to extend bent erectly from a body of the connecting member so that the electrical connection can be obtained by causing said blade to penetrate an insulation cover layer of the electric wire only by the tightening action of the terminal screw;
a pair of means for pressing both sides of a connecting portion of the electric wire by bending both end edge portions of right and left sides of the body inwardly and spaced apart from said body;
a pair of anti-motion pieces made of electrically conductive material with, a terminal base maintaining the connecting member horizontally at a predetermined distance from said pressing means, said pressing means and anti-motion pieces having inwardly turned resilient ends terminating at different distances from said body;
and
coupling groove means for coupling with a stopper protruded from a terminal board to prevent the turning of the connecting member together with turning of the screw upon screwing the terminal screw for the electrical connection of the connecting member with terminal board.
