Patented Jan. 6, 1931 UNITED STATES PATENT OFFICE MILTON ALDEN, OF SPRINGFIELD, MASSACHUSETTS, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO RADIO INVENTIONS, INQ, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK Application filed January 7, 1927. Serial No; 159,592.
My invention relates particularly totermineral clips or conductors to facilitate .con-
nclption with battery binding posts and the li e.
One object is to provide a simple terminal which can be readily applied and by which the end of a flexible conductor can be readily handled and identified. Other details will be understood from the following specification: The terminal is preferably formed 'of a single sheetmetal blank stamped and formed to provide three parts viz: a socket portion attached to the wire, a forked portion to engage a binding post, and an extension at the opposite end serving as a handle and identifying tag.
Fig. 1 shows one form of blank from which a terminal is to be made (much enlarged).
Fig. 2 is an edge view of the same with a conductor wire partially attached.
Fig. '3 is an edge view, the terminal being completely attached to the wire and its insulation.
Fig. 4 is a plan view showing a completed terminal.
Fig. 5 is an edge view of a modified construction bent near the socket;
Fig. 6 is a plan view of the same.
The bod or socket portion 10 has a loop 11 adapte to receive the end 12 of a wire. The wings 13, 13 are adapted to be formed around the insulation 14 of the conductor to hold the parts together.
The forked end has two spaced fingers 15, 16 adapted to slip on the end of a binding post beneath the usual screw or nut. One finger may be shorter than the other to facilitate placing the clip into position.
The opposite end 17 of the clip forms a convenient finger piece by which the wire may be handled. This is particularly desirable where the wire has to be connected in a confined or inaccessible place as in a radio set. The narrow neck 18 is easily bendable so that the wire can be brought in at any acute angle i. e. parallel to the fork, at right angles or any other angle thereto.
This part 17 may have. stamped or printed in or on it some character or letter denoting the place to which that particular wire is supposed to be attached as for instance 13+ meaning tothe positive terminal of the B battery. I
In Fig. the two fingers 15 and 16 are of the same length.
In the form shown in Figs. 5 and 6 the end 17 is made much longer than 17 and has asecond socket 19 at its other end so that the wire is held more securely. This ensures holding the wire in position where it belongs and preventscontaot with other elements. The notation on this tag portion 17' indicates that that conductor is to be connected to the negative of the O battery if a O battery is used or to the negative of A battery if no G battery is used.
One end 15 of the fork may be pointed to facilitate its attachment to spring clips such as are frequently used. By making this point small enough it may be conveniently inserted in a perforated binding post. Thus the terminal is universalthat is it can be readily attached to any one of the various battery terminals commonly employed.
By marking the extension 17 or 17. with the letter or other indication of the element to which the connection is tobe made I do away with the necessity of special identification tags.
It may be desirable under certain condif tions to cover the tag or handle portion 17 or 17f with'celluloid paint, insulating varnish or other similar material to preclude possibility of shocks when making connections to high voltage terminals.
The device disclosed eflects a distinct saving in manufacturing and assembling cost over that of the usual separate marking tag and contacting terminahand maybe punched complete without re-handling by means of a compound punching and forming die.
' I claim:
An electric connecter including a body portion, a forked portion integrally formed at one end of said body portion for contacting with a binding post or the like, a loop outstruck from said body port-ion for joining a conductor to said body portion, an in tegral wing formed on one side of the body portion and disposed in alignment with said 100 whereby said wing is adapted to engage sai conductor, another wing member formed integrally with said body' on the opposite side thereof and adapted to engage said conductor at a point spaced from said first men tioned wing, said wings providing a two point contact with said conductor; an extension integrally formed at the opposite end of said body portion, said extension being adapted to afford convenient means for grasping with the hand for attaching to and detaching from the post, and being adapted to carry any suitable identifying indicia.
