Y., assignor to Burndy Engineering Company, Inc., a corporation of New York Application January 4, 1945, Serial No. 571,227

My invention relates to electric terminal connections and more particularly to a terminal for attachment to a terminal board to which electrical connections are made.

The objects of my invention are to provide a terminal which occupies relatively small space, to which electrical connections may be quickly made, and which can be quickly and permanently attached to a terminal board.

I accomplish these and other objects and obtain my new results as will be apparent from the device described in the following specification, particularly pointed out in the claims, and illustrated in the accompanying drawing in which:

Fig. l is a longitudinal cross-sectional View of my device.

Fig. 2 is a side-View illustrating the method of installations.

Fig. 3 is a similar view of my device attached to a terminal board.

Fig. 4 is a side-view partly in section of a modification of my device.

Fig. 5 is a side-view of another modification.

Fig. 6 is a side-View of a completed connection.

Referring more particularly to the drawing reference numeral l designates a tubular sleeve of metal having an eyelet ll secured thereto by soldering or brazing at the junction l2. The eyelet may be secured to the sleeve at a point sufiicient to allow the upper and lower sections of the sleeve to have ample length for securing a conductor thereto.

The eyelet II contains the usual shoulder l3, and free edge It for rolling the edge into a clamping shoulder as shown in Fig. 2, by means of a tool, hereinafter described.

For attachment to a Wall section, the tubular sleeve and integral eyelet is passed through an aperture E in the wall [6, as shown in Fig. 2. An eyelet supporting tool l1, having a bore I8 is inserted over the free end of the sleeve supporting the shoulder E3 of the eyelet.

A rolling tool- I 9 similarly provided with a bore 26 is inserted over the remaining end of the sleeve Hi. The rolling edge 2i of the tool is shaped so as to force the free edge IA of the eyelet to roll over and secure the eyelet with attached sleeve securely to the wall section I6.

The final result is illustrated in Fig. 3, wherein the sleeve and attached eyelet are fully secured 3 Claims. (Cl. 248-56) 2 to the wall section [6, with the tool I1 and I9 Withdrawn.

One end of the sleeve may be formed into a terminal lug 25, as shown in Fig. 4, provided with a central aperture 26, or the sleeve may be provided with slots 30, shown in Fig. 5, for providing resilient prongs 3| for resiliently engaging a pinjack, not shown.

Various methods may be used to secure a conductor to the sleeve. In Fig. 6, a familiar type of indentation 40 is employed which forces the metal of the sleeve with tight engagement into the inserted conductor 4l'.

In the foregoing I have provided a construction for accomplishing, the objects of my invention. The connection is compact, inexpensive to make and install, contains fewer parts than are usually found, and provides a sound connection for various electrical installations.

I have thus described my invention, but I desire it understood that it is not confined to the particular forms or uses shown and described, the same being merely illustrative, and that the invention may be carried out in other ways without departing from the spirit of my invention, and, therefore, I claim broadly the right to employ all equivalent instrumentalities coming within the scope of the appended claims, and by means of which, objects of my invention are attained and new results accomplished, as it is obvious that the particular embodiments herein shown and. described are only some of the many that can be employed to attain these objects and accomplish these results.

I claim:

1. A connector for attachment to an apertured wall section comprising a body section having a cylindrical portion, a shoulder extending circumferentially about the cylindrical portion, and a circumferentially extending portion in non-movable relationship to the cylindrical portion having a diameter sufficient to enable the connector to be fitted into an aperture of a wall section as a unit and being bendable to permit it to be forced in a plane transversely to the longitudinal axis of the cylindrical portion for supporting the cylindrical portion rigidly in position on the wall section.

2. The connector of claim 1, wherein the shoulder and. the circumferentially extending portion comprise an eyelet which is made integral with the cylindrical portion.

3. A connector for attachment to an apertured wall section comprising a body section having a cylindrical portion, a shoulder section extending oircumferentially about the cylindrical portion, and a circumferentially extending portion having a diameter sufiicient to enable the connector to be fitted into an aperture of a Wall section and being bendable to permit it to be forced in a plane transversely to the longitudinal axis of the cylindrical :portion for supporting the cylindrical portion -.in position on the Wall section, said shoulder section and circumferentially extending portion permanently being mounted to the cylin- 15 drical portion to form a unitary assembly before insertion into the aperture of the wall section.
