Aug. 16, 1932. c. F. CARTER ELECTRICAL CONNECTER Filed May 19, 1930 Inventor fhnewejf'dmzer A tiomey Patented Aug. 16, 1932 UNITED STATES PATENT OFFICE ELECTRICAL CONNECTER Application filed May 19, 1980. Serial No. 453,698.

This invention relates to new and useful improvements in electrical connecters for electrical conductors. The principal object of this invention is to provide a connection for conductor terminals whereby a firm and intact connection may be made.

Another important object of the invention is to provide a connecter which is capable of connecting conductor terminals in a quick and lasting relation.

Several other important objects and advantages of the invention will become apparent to the reader as the description of the invention proceeds hereinafter.

In the drawing Figure 1 represents a side elevational view of a connecter enclosed by flexible tubing.

Fig. 2 represents a side elevational view of the connecter partly withdrawn showing the tubein section.

Fig. 3 represents a longitudinal sectional view through the connecter taken substantially .on the line 33 of Fig. 2 with tube sections removed.

Fig. 4 is an enlarged fragmentary sectional view disclosing certain parts of the connecter.

Fig. 5 represents a perspective view of the expansible bushing.

Fig. 6 represents across sectional view of the bushing taken substantially on the line 6-6 of Fig.5.

Referring to the drawing,.where1n-l1ke numerals designate like parts, it can be seen that numerals 5 and 6 represent adjacent ends vided with the usual insulating jac et '7,

The novel socket construction generally referred to by the numeral 8 is rovided for the conductor terminal 5, while the plug structure 9, is provided for the conductor terminal 6. The socket structure 8 is provided with a pocket 10 extending inwardly from one end thereof to receive the conductor terminal 5, and securin means 111s placed in this pocket 10 to reta n the conductor ter minal properly connected to the socket structure 8. v

Of course, this must be a current conductive connection. A pocket 12 extends mwardly from .the opposite or outer end of of a pair of conductors which may be pro the socket structure 8 and terminates at its inner end before communicating in the pocket 10. A pin 13 is disposed transversely thru the socket structure 8 at the inner end of the pocket 12. The plug structure 9 includes a cylindrical body 145 provided with a pocket 15 at one end to receive the conductor terminal 6, wherein the terminal is secured by some of the aforementioned means 11.

The outer end of the body 14 is provided with an elongated toothed extension 16, which in itself is provided with a reduced and threaded extension 17, the portion between the outer ends of theextension 16 and the extension 17 being tapered as at 18. i

Fig. 5 discloses the bushing structure which .is employed in conjunction with the aforementioned parts. This bushing is tubular and is denoted by the numeral'19. Slits 20 extendinwardly from one end of the bushing and terminate inwardly of the oppositeend thereof, while slits 21 extend in inwardly from the opposite end of the bushing and terminate inwardly from the first-mentioned end of the bushing, the latter slits bein in interlapping relation with respect to the rstmentioned slit, as in the manner clearlyshown in Fig. 5.

Numeral 22 discloses a stationary internally threaded bushing provided with notches 23 at one end to receive the aforementioned pin 13 when the bushing 22 is inelosed with-- in the pocket 12 as in the manner -shown in Fig. 3. The opposite end of thebushing 22 is tapered as at 24 for engagement within the internally beveled adjacent end of the bushing 19. when the bushing 19 is properly disposed over the threaded extension 17. The opposite end of the bushing 19 is I also internally beveled so as to engage against the tapering portion 18 of the body 14. After the parts are assembled on'the plug structure 9 as in the manner shown in Fig. 4, the same is inserted into the pocket 12 of the socket. structure 8 and by rotating the plug 9, the body 14 will be fed toward the bushing 22; during which maneuver the bushing 19 expands and confines against the mner s1de of 10( l the pocket 12, in snug contact so as to firmly connect the plug body 14 to the socket structure 8.

Numerals 25 and 26 represent flexible tube sections which are engaged over the socket structure 8 and plug structure 9 respectively. By engaging the shapes and ends of these flexible sections, in abutting relation as shown in Fig. 1, the entire connection will be fully covered and protected.

While the foregoing specification sets forth the invention in definite 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 thus described my invention, what I claim as new is A connecter for electrical conductors comprising a socket having an axially disposed chamber, a pin extending diametrically through the chamber, a plug including a body, an axially disposed threaded extension on the body, the body having a bevelled seat tapering toward the extension, a bushing threaded on the extension having a tapered inner end defining a seat, an expansible sleeve disposed on the extension and having its ends fitted on the first and second mentioned seats, the plug being slidable in the socket, said bushing having a diametrically, extending slot on its outer end for receiving the pin in the socket, whereby upon turning movement of either the socket or the plug, the bushing can be threaded on the extension for expanding the sleeve.

In testimony whereof I afiix my signature.

CLARENCE FREEMONT CARTER.
