Abstract

A connecting terminal of electrically conductive material is in the form of a flat plate having first and second tabs which are stamped from the plate and bent upwardly from the same surface of the plate. The first tab is reversely bent to overlie the plate in spaced substantially parallel relation thereto for receiving an insulated wire and the second tab is disposed at an acute angle to the plate and is directed opposite to the first tab for anchoring the free end of the wire to the terminal. The first tab is provided with an elongated slot in the bent portion thereof so that on subsequent clamping of the wire by the application of pressure by opposed electrodes and the passage of current through the electrodes, the insulation will be burned off the wire under the first tab. The elongated slot allows for the escape of gasses and burned insulation material so as to insure a good electrical connection between the conductive core of the wire and the terminal.

Claims

1. A connecting terminal comprising plate means having a hook-like tab member protruding from one surface thereof and extending over said plate means in spaced substantially parallel relation thereto for receiving an insulated wire thereunder, means defining an elongated aperture in the bight of said hook-like tab member to facilitate the dispersal of gases and insulating residue during a subsequent fusing operation of said wire to said terminal and clamping means protruding from the same surface of said plate means as said hook-like tab member for securing the free end of said wire to said terminal, said clamping means being comprised of a piece protruding from said one surface of said plate means at an acute angle thereto and facing in the opposite direction from said hook-like tab member.

2. A connecting terminal as set forth in claim 1 wherein said tab member and said piece are of one-piece integral construction with said plate means which is of electrically conductive material.
