1 Claim.

This invention relates to electrical conductors,

particularly to a connector for conductors arranged at an angle to each other.

The primary object is to provide a novel arrangement for connecting one pair of concentric conductors with another pair of concentric conductors wherein one pair is disposed at an angle to the other pair, which arrangement is of simple yet sturdy construction and can be readily disconnected.

With the above and other objects in view which will be apparent from the following description to those skilled in the art to which the invention appertains, the present inventionv consists in certain features of construction and combinations of parts to be hereinafter described with reference to the accompanying drawing and then claimed.

In the drawing which illustrates a suitable embodiment of the invention:

Figure 1 is a side elevation of the conductors and connector; and

Figure 2 is a section through the arrangement of Figure 1, showing the same in greater detail.

Referring to the accompanying drawing, the invention is illustrated as applied to a vertical conductor I and a horizontal conductor 2. The vertical conductor I is comprised of concentric current conducting elements 3 and 4 electrically insulated from each other by a sleeve 5 of suitable insulating material. The end of the outer element 4 is externally threaded and the inner element 3 projects beyond the element 4 and is similarly externally threaded.

Associated with the conductor I is a flanged sleeve member 6 containing an internally threaded extension member 1 which is electrically insulated by insulation Il and extends beyond the sleeve member 6. The inner element 3 is threaded into the extension member 1 and the outer element 4 is threaded into the sleeve member 6.

The horizontal conductor 2, like the conductor I is comprised of concentric tubular current conducting

elements

8 and 8 electrically insulated from each other by an insulating sleeve I0.

The outer element 4 of the conductor I is electrically connected to the outer element 8 of the conductor 2 by the sleeve member 6 and an elbow member II having its ends recessed to partially surround the sleeve member 6 and conducting element 9. The sleeve member 6 and element 9 are securely clamped within the recessed ends 0i the elbow member I I by recessed caps I2. Screws I3 secure the caps I2 to the ends of the elbow member and when tightened securely clamp the sleeve member 6 and element 9 in good electrical contact with the elbow member I I.

Connection between the inner conducting

elements

3 and 8 is aorded by a plug I4 threaded into the end of conducting element 8 and having a recessed end which receives the extension member 1. A recessed cap I5 secured by screws I6 to the plug I4 clamps the extension member 1 in good electrical engagement with the plug I4.

By removing the screws I3 and one cap member I2 and the screws I6 and cap member I5 the conductors I and 2 can be readily disconnected.

The arrangement described provides a simple and sturdy expedient for connecting electrical conductors, particularly electrical conductors arranged at an angle to each other and each comprising a pair of concentric tubular conducting elements.

This arrangement is particularly adaptable for use in high-frequency induction heating equipment wherein current is conducted from a transformer to a heating coil.

It is to be understood that various changes may be made in the detailed construction and arrangement of the parts described without departing from the spirit and substance of the invention the scope of which is defined by the appended claim.

What is claimed is:

A pair of inner and outer concentric current conducting elements, means electrically insulating said elements from each other, a second pair of inner and outer concentric current conducting elements arranged at an angle to the rst pair, means electrically insulating said second pair of elements from each other, an electrical connector having recessed end portions partially surrounding said outer conducting elements, recessed caps partially surrounding said outer conducting elements, means securing said caps to said end portions in clamping relation about said outer elements, one of said inner elements having an end portion projecting beyond its concentric outer element into intersecting relation with the axis of the other inner element, a second connector extending from within said other inner element and having a recessed end portion partially surrounding said projecting end portion, a cap surrounding the remainder of said end portion, and means securing said last mentioned cap to said last mentioned end portion in clamping relation about said end projecting end portion.
