ELECTRICAL CONNECTER Filed April 1. 193e 2 sheets-shane IIU 52am@ EME Attorney@ Patented Feb. 9, 1937 UNITED STATES PATENT OFFICE 1 Claim.

This invention appertains to new and useful improvements in electrical connecters.

The principal object of the present invention is to provide an electrical connecter for electrical conductors which is of the swivel type, wherein the parts are so interrelated as to materially reduce the occurrence of wear which is the principal objection to the present day use of swivel connecters.

Another important object of the invention is to provide an electrical connecter of the swivel type wherein the parts are sturdily constructed and interconnected to the end that the assembly will not be susceptible to the ready development oi defects.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:-

Figure 1 represents a side elevational view of a connecter.

Figure 2 is a longitudinal sectional view through the device.

Figure 3 is a section on line 3-3 of Figure 1.

Figure 4 is a cross-sectional view on the line 4--4 of Figure 2.

Figure 5 is an inside elevational view of one section of the connecter.

Figure 6 is an inside elevational view of the section complementary to the section shown in Figure 5.

Figure 7 represents an inside elevational view of the opposed section of the connecter.

Figure 8 is an inside elevational view of the section of the shell complementary to the shell section shown in Figure 7.

Figure 9 is an end elevational view of the structure shown in Figure 5.

Figure 10 is an end elevational view of the structure shown in Figure '7.

Referring to the drawings wherein like numerals designate like parts, it can be seen that the connecter is made up of the unit generally referred to by numerals 5 and 6. The unit 5 consists of the cylindrical shell made up of the sections L -b. The sections a--b are provided with the conductor inlet necks 'I--1 at one end and with inwardly disposed flanges 8 at their opposite end.

Suitably secured in the section a is the sleeve 9 of current conducting material which projects a substantial distance beyond the end of the unit 5 and is there provided with a circumferentially extending shoulder IIJ. Numeral II is a dielectric core for the sleeve 9 having the contact pin I2 disposed longitudinally therethrough and in one end of which the adjacent end of the conductor I3 is anchored as at I4. The conductor I5 has its end suitably connected to the adjacent end of the sleeve 9.

The unit 6 consists of the shell sections c-d and each of these sections c-d is provided with a reduced conductor receiving neck portion I6 at one end and a rabbeted portion I'l at its opposite end receiving the semi-circular ring I8. These rings I8 are secured to the section c-d by a screw I9 and engage over the shoulder I0 on the sleeve 9. Thus a swivelled connection is established between the units 5 6. It can also be seen in Figure 1, that each of these units has its sections secured together by screws or bolts 20.

Referring to Figure 2, it can be seen that the section c of the unit 6 is provided with an internal boss 2l provided with an axial bore receiving the tube 22 in which is located the coiled compressible spring 23, urging the contact member 24 in a direction to engage the contact pin I2. (See Figure 2).

As is apparent in Figure 2, the semi-circular rings I8 are of current conducting material and jumpers 25 extend through the wall of the section 6 to connect with one of the conductors 26. The

other conductor 2l is anchored as at 28 in the -I tube 22.

It can now be seen, that with the elements thus sturdily assembled and positively interlocked, the units 5-5 can rotate with respect to each other, as a swivel, without affecting the electrical connection between the same.

While the foregoing specification sets forth the invention in specic terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention what is claimed as new is:-

A swiveled connecter comprising a pair of hollow sections, a sleeve of current conducting material projecting from one of the sections and provided with an insulating filler, an electrode extending longitudinally through the ller, the outer end of the sleeve being provided with an outstanding circumferentially extending shoulder in spaced relation to the adjacent end of the corresponding section, the other section being provided with an internal boss, said boss being provided with an axially spring pressed contact engaged with the electrode of the complementary section, the spring contact carrying section provided With an annular conductive member at its end opposed to the complementary section, said annular member being interposed between the shoulder on the sleeve and its companion section end, affording a swivel and electrical connection between the Sections.
