ELECTRICAL CONNECTER'.

Application led November 10, 1921. Serial No.4514,231.

To aZZ whomz't may concern.' y

Be it known that I, ALFRED E. LATHAM, acitizen of the United States, and a resident of the city of New York, boroughof Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Electrical Connecter, of which the following is' a full, clear, and exact description.

This invention relates to an electrical connecter, and has for an object the provision of means whereby a circuit wire may vbe simply but very securely fastened within the connecter so that it will stand greater strains and will make a much more eilicient elec trical Contact.

Another object resides in th particular construction and arrangement of parts which are hereinafter described and claimed and* shown in the accompanying drawings.

The invention 'is illustrated in the drawings, of which- Figure 1 is a longitudinal section taken Fig. 2 is a side elevation showingthe two parts of the connecter spaced apart.

Fig. 8 is an end view of the plug portion of the connecter. u

The drawings illustrate a preferred form. of my invention but it is understood that modifications in the arrangement 'andfconstruction of the parts may be adopted without departing from the general spirit of the y inventiony as set forth hereinafter.

This invention as shown in the drawings comprises a socket portion A and a plug portion B. The socket portion comprises a shell 1 of any suitable insulating material, v such as ebonite, having disposed in a suitable portion therewithin a metallic socket body portion 2. This socket is provided with a bore 3 threaded as at 4: along its outer edges and provided with a curved shoulder 5 at an intermediate portion. This bore is reduced toward the inner end, as at 6, and is provided with a shoulder l7, Aand beyond this is still further reduced as a 'small bore 8. Midway of the body portion of the socket 2 are bayonet pins 9 and 10 which extend in opposite directions therefrom through the ebonite shell 1 to forni'means for fastening the connecter to any suitable co-operating member. .A contact pin l11 extends through the aperture or bore 8 and has a ange 12 thereon engaging the shoulder 7. This flange is backed by a spring 13, the

tion of said head to engage with the threads other end of which bears against wires 14. These wires passthrough a bore 15 in a metal plug portion andare bent around over the end thereofv to be gripped between the projecting portion 17 of the plug and the walls of the socket andto bear against the curved shoulder 5 previously mentioned. The projecting plug portion 17 is provided with threads to engage in the threaded bore 4.

rI he plug meinberis provided, likewise, with an insulating body portion 18 provided with a knurled ring flange 19 and at its front end with a depressed recess 20 into which the end of the shell 1 extends as the plug portion 16 is screwed into the socket portion 2. The plug portion 16 and the insulating body portion 18 are provided with aligning apertures forming the bore 21 through which the conductor 22 extends. conductor is stripped so that the wires maypass through the bore 15 with their ends bent .over and contacting alongthe outer surface of the projectmg portion 17.

cess 20 embraces the end ofthe shell 1, the

joint between the body portion 18 and the socket 2 is very perfectly insulated by the engagement` of the insulating shell. y

In this manner I have provided. a simple, eliicient connecter device thatcan Vbe readily y disassembled, and when assembledl forms a compact structure in which the wires are` very firmly and strongly gripped.

What I claim is:

1. An electrical connecter which comprises a conducting socket portion, a sleeve of insulating material surrounding the same, said l The end of the Vsocket portion having 'an interior bore threaded at one end, a plug portion of conductin material,- a sleeve of insulating material t erearound, said lastmentioned sleeve on the face adjacent the socket portion havl ing a recess into which the end of the iirstmentioned sleeve extends,`said plug having a projecting head to extend into the bore of the socket portionand threaded along a por- 1 inthe bore of the socket whereby the socket member and the plug member are tightly engaged.

2. An electrical connecter'whieh comprises a conducting socket portion, a sleeve of insulating material surrounding the same, said socket portion having an interior bore threaded at one end, a plug portionof conducting material, 'a sleeve of insulating material therearound, said last mentioned sleeve on the face adjacent the socket portion having a recessinto which the end of the firstmentioned sleeve extends, said plug having a projecting head to extend into the bore of the socket portion and threaded along a portion of said head to engage with the threads in theb'ore of the socket whereby the socket member and the plug member are tightly engaged, said extending head portion having a bore therethrough, and conducting wires eX- tending through said bore and beyond the end of the head, said Wires being bent backwards along the outside surface of the head to b-e gripped between the Walls of the socket and the head. n
