Application filed m 'aa,

My invention relates to electrical connectors and more particularly to a plug for attaching an electric cord to a socket.

The object of the invention is to provide a connecting plug having abutments, for assistingin supporting the plug when it is connected into a socket in a horizontal position, and a'handle by means of which the plug may be inserted in a socket and withdrawn therefrom, thus tending to overcome the usual practice of removing a plug from its socket by jerking on'the electric cord.

' With this and other objects in view, the invention resides in the features of construction and arrangement of parts herein deing screws 10 for securing the ends of the ,wires of an electric cord 11 which enters recess 6 through an insulating bushing 12.

That part of recess 6 not occupied by block 7 is preferably lined with an insulating ring 13 and an insulating disk 14, through which insulating bushing 12 extends. The rear wall of shell 5 preferably slopes outwardly and forwardly from its median line so that cord 11 may extend rearwardly at an angle from the shell without interfering with a handle 15 secured to or formed on shell 5 parallel to its center line.

In order to assist prongs 9 in supporting the block when it is inserted horlzontally into a socket, abutments 16 are secured to or formed on the shell in alignment with handle 15 and with their front .ends flush with or ex- Even when the prongs fit loosely in a horizontally disposed socket the lower abutment supports the plug in a horizontal position;

two abutments being provided so that the plug may be inserted in a socket with either side up. When an electric cord is equipped with one of these plugs, it is found that there 1s little tendency upon the part of the user to remove the plug from the socket by jerking upon the cord, as the shape of handle 15 inembodiment of my invention, it will be understood that modifications may be made without departing from the-spirit thereof and, hence,

I do not wish to limit myself to the precise 6 construction set forth but consider that I am at liberty to make such changes and alterations as fairly come 'within the scope of the appended claims.

I claim 1. A connecting plug including a shell, an nsulating block secured in the shell, connecting prongs extending through the block, means for securing anelectric cord to, the prongs, a handle formed on the shell, and an abutment formed on the shell substantially flush with the front end thereof.

2. A connecting plug including a shell, an apertured handle formed on the shell, an in-. sulating block-secured in the shell, connecting prongs extending through the block, an insulating bushing extending into the shell adjacent the handle for accommodating an electric cord to be connected to the prongs, and abutments formed on the shell substantially flush with the front end thereof.

3. A connecting plug including a shell haV- ing a recess, an insulating block secured in the recess flush with the front end of the shell, prongs extending through the block, binding screws on the prongs, an insulating bushing extending into the recess at an angle to the axis of the plug, a loop-shaped handle formed on th shell adjacent the bushing, and abutment formed on the shell substantially flush 95 with the front end thereof.

In testimony whereof I have signed my name to this specification.
