2 Claims.

This invention relates to an electrical connection and it aims to provide a novel construction which will avoid tangling, undue-straining and breaking of the wires, and more specifically aims to provide a construction in which the parts are swiveled together.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawing illustrating an operative embodiment.

In said drawing:--

Figure 1 is a view of the connection in side elevation,

Figure 2'is a vertical sectional view on an enlarged scale taken on the plane of line 2-2 of Figure 1,

Figure 3 is an inverted plan view of the connection.

Figure 4 is a cross sectional view taken on the line 4-4 of Figure 2, and

Figure 5 is a cross section'taken on the line 55 of Figure 2.

Referring specifically to the drawing, a body or sectionlO of insulation has a neck 11 which extends into and is swiveled in a second body of section 12 of insulation. Extending from the body 12 are metallic conductor prongs 13 and 14, respectively, preferably made in a single piece and having

tangs

15 and 16 by means of which they are detachably bolted as at 1'7 and 18 to the body 12. Prong 13 at the inner end has a ring 19 integral therewith and disposed at a right angle thereto. After the prong 13 is secured in place, but before the prong 14 is mounted, a conductor sleeve 20 is secured to the neck 11 in any suitable manner, for instance, by friction, and the same has an annular flange at 21 which underlaps the ring 19. Thus the body 10 carries the sleeve 20 and flange 21 constantly moved in contact with the ring 19. 'A conductor strip 22 is formed as a tongue on sleeve 20 and secured in any suitable manner as by means of screw 23 to the body 10. One of the feed wires for the currentis shown at 25 and is fastened in place in contact with strip 22 by means of the screw 23. The companion conductor is shown at 26 and is secured by a screw 2'7 in contact with a conductor 28 which terminates centrally of the plug 10 in an enlargement 29 at the base of an extension 30 of neck 11. The outer surface of the enlargement 29 is preferably spherical. The prong 14 has an inward extension at- 31, preferably of less thickness than the remainder of the prong to alford resilience, and which extension 31 is in constant wiping contact with the enlargement 29. As a result the wires will not become twisted since movement of body 10 relative to body 12 maintains electrical contact 1: the

flanges

19 and 21 and enlargement 29 and Various changes may be made provided they fall within the spirit and scope of the invention.

What is claimed is: 1. A connection of the class described comprising a body section, conducting elements se-. cured to the body section, one of the elements terminating in a ring, the other element having a resilient extension spaced outwardly of the ring, a section of insulation abutting the body section and having a neck extending thereinto, a conducting sleeve carried by said neck and having a flange underlapping said .ring, a conductor strip carried by the section of insulation in conducting relation to said sleeve, a conductor member carried by the section of insulation extending through said neck and engageable by said resilient extension, and an extension on said neck, said conductor member having a spherical surface at the base of said extension directly'engageable by said resilient extension.

2. A connection of the class described comprising a body section, conductingelements secured to the body section, one of the elementsterminating in a ring, the other element having a resilient extension spaced outwardly of the ring, a section of insulation abutting the first mentioned section and having a neck extending thereinto, a conducting sleeve carried by said neck and having a flange underlapping said ring, a conductor strip carried by the section of insulation in conducting relation to said sleeve,

a conductor member carried by the section of insulation extending through said neck and engageable by said resilient extension, an extension on said neck, said conductor member having a spherical surface at the base of said extension directly engageable by said resilient extension, and-an operating sleeve detachably secured to the first mentioned section and enclosing the second mentioned section, said sleeve having an outwardly extending flange adjacent its free end.
