Application'July 9, 1954, Serial No. 442,369

2 Claims. (Cl. 339-276) The present invention relates to new and useful improvements in lugs used in providing electrical connections.

An important object of the present invention is to provide a lug of strap metal construction adapted for bending upon itself to provide a loop in which one or more wires are clamped and soldered.

Another object of the invention is to provide a bendable locking tongue on one end of the lug adapted for adjustable locking engagement in an opening in the lug in accordance with the size of the loop formed in the lug depending upon the number of wires to be clamped thereby.

A still further object is to provide a connector lug of this character of simple and practical construction, which is efficient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purpose for which the same is intended.

These, together with other objects and advantages which will become subsequently apparent reside in the details of constructionand operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view showing a conventional type of socket equipped with a number of the connector lugs;

Figure 2 is an enlarged perspective view showing one of the lugs prior to being shaped to form the connector;

Figure 3 is asimilar view showing the initial step in bending the lug;

Figure 4 is a similar view showing the lug bent to provide a wire clamping loop and with the locking tongue inserted in the opening of the lug;

Figure 5 is an enlarged vertical sectional view taken on a line 5--5 of Figure 1; and

Figure 6 is a vertical sectional view showing the lug shaped for clamping a single wire therein.

Referring now to the drawing in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a bendable strap metal lug having one end embedded or otherwise suitably anchored in a conventional type of socket 6 and with the lug extending upwardly therefrom.

An opening 7 is formed in the lower portion of the lug 2 ,745,082 Patented May 8, 1956 ice at-a point immediately above the upper surface of the socket 6. The upper end of the lug is formed with a locking tongue 8 which extends longitudinally outwardly at the free end of the lug.

The lug is bent horizontally along a transverse line indicated at 9 in a point. above the opening 7, in the manner indicated in Figure 3 of the drawing and the horizontally bent portion 10 of the lug is then bent rearwardly upon itself to form a loop 11, as indicated in Figure 4 of the drawing.

A plurality of wires 12 are inserted in the loop 12, as illustrated in Figure 5, or a single wire 13 may be inserted in the loop, as shown in Figure 6. The single wire 13 or the group of wires 12 are clamped in the loop in a suitable manner by compressing the loop and wires may then be soldered therein to permanently secure the wires in position.

Thefree end portion 14 of the lug is extended downwardly in confronting relation at one side thereof and the tongue 8 is inserted in the opening 7 of the lug and bent upwardly at the opposite side thereof, as indicated in Figure 5, to lock the tongue in position in the opening of the lug. I

The lug accordingly provides a permanent soldered connection for the wires.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerousmodifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly all suitable modifications and equivalents may be resorted to, fallingwithin the scope of the appended claims.

What is claimedas new is as follows:

1. An electrical connector comprising a bendable strap metal lug having. one end anchored in an upstanding position to a supporting I device, a compressible loop formed at the free end of the lug and adapted to receive a circuit wire in a crosswise position with respect to the lug for clamping the wire transversely in the loop, said lug having an opening below the loop, and a bendable locking tongue at'the free end of the lug and engageable in said opening.

2. An electrical connector comprising a bendable strap metal lug having one end anchored to a supporting device and projecting outwardly therefrom, a closed loop formed in the lug and adapted for receiving a wire therein ma crosswise position with respect to the lug, and means locking the free end of the lug to itself at a'point inwardly of the loop to clamp the wire in a transverse position in the loop.
