UNITED STATES PATENT OFFICE ELECTRICAL CONNECTOR Karl J. Mosebach, Pittsburgh,- Pa.
Application January 11, 1945, Serial No. 572,302
2 Claims. (01. zoo-115.5)
My invention relates to electrical connectors and more particularly to those of the feeder tap type such as are employed in temporarily tapping trolley wires and the like for the utilization of electrical current for electrically-driven machines, welding apparatus, etc.
Such connectors or taps usually include fuses for the purpose of safety. 1
One object of my invention is to provide a connector device of the character referred to wherein the fuses can be more readily placed and replaced than in the case of various types of connectors or feeder taps heretofore employed, and wherein no tools such as screw drivers, or wrenches are required in the changing of the fuses.
vAnother object of my invention is to provide a device of the character referred to, containing a fewer number of parts than are commonly employed.
Still another object of my invention is to provide a feeder tap that will engage a trolley wire conductor more firmly than various types of taps heretofore employed and which can conveniently and safely be manipulated by the operator.
Some of the forms which my invention may take are shown in the accompanying drawing wherein Figure 1 is a longitudinal sectional view through a connector, and Fig. 2 is a view showing a modification thereof.
A connector comprises a tubular body or casing 3 of insulating material such as impregnated fabric or a molded plastic. A bushing 3 of simi lar insulating material has snug fit with one end of the tube 3 and is held against accidental dis placement by'a series of pins A cable 65 ex tends loosely through the bushing l and contains the usual conductor wires or wire "i that extend through the end wall or bottom of a coupling socket 8 that is screw-threaded to receive a coupling plug 9, so that when the coupling plug is screwed tightly into the socket, the ends or the wires 1 will be firmly clamped or gripped. The plug 9 has a stud-like extension it that extends into the hole in the end of the socket ii to assist in holding the Wires. The plug 3 also is provided with askirt-like extension ii that has a series of axially-extending slots ii! that are yieldable and will therefore serve as a holding clip for a fuse- I3.
At its other end, the tube 3 contains a threaded bushing 14 that closely fits the tube and is anchored therein by a series of tubular rivets I 5. An insulating-protecting sleeve 16 tightly encircles the tube 3 to cover the exposed ends ,of the rivets I5.
A screw-threaded plug i1 is detachably held in place by the bushing l4 and has a skirt portion slotted at various points as indicated at l8 so that it will serve as a holding clip for one end of the fuse H! as in the case of the coupling plug 9.
The plug ll has an extension I 9 formed integrally therewith or rigidly attached thereto in some other suitable manner. This member it serves as one of the gripping jaws for a trolley wire 25 or other electrical conductor. A cooperating jaw is shown at 22 and has a handle portion 23 that has an insulating covering 24. ihe jaw 22 is pivotally connected at 25 to the jaw it. A spring :25 yieldably holds the jaws in gripping engagement with the conductor wire, and the jaws have a series of grooves for gripping wires of various thicknesses.
A disc of insuiating material is connected to the plug it by a screw it and serves to reduce danger or" the operators hand, when grasping the tube from accidentally coming into engagement with the jaw members. ihe disc or plate 2?? has a slot at it to permit the handle to be moved closely against the tube 3 when opening the jaws. it will be seen that when the tube 3 is hem in the hand, the users fingers or thumbs can he moved against the handle at 23 to open the jaws when applying the tap to or removing it from a wire.
in connecting the device to the wires or wire in the cabie t3, the plug l! is removed from the tube and the coupling members 8 and slid out of the tube at its iorward end, these members being of slightly less external diameter than the internal diameter of the bushing M. Thereupon the cable 55 will be slid forwardly through the bushing it and through the tube until it projects from the forward end of the tube. Thereupon bared wires from within the cable will be inserted into the socket member it and bent lateraliy. The plug 9 will then be screwed tightly into the socket 8, by the use of wrenches, thus firmly gripping the wire ends. The stud It will assist in gripping the wires in the hole at the bottom of the socket and may also serve to spread the wires. It will assist in the gripping and holding action even though a single wire is being clamped in the coupling members.
The cable 6 and the coupling can then be drawn to the position shown in Fig. 1, the fuse 3 inserted in the holding clips at H, and the plug I! screwed into place. When it is necessary to replace the fuse, the plug I'I will be unscrewed, without the necessity of disturbing the coupling members 8-9.
Referring to Fig. 2, I show a plug II that serves substantially the same purpose as the vplug H, but instead of carrying a jaw, it is simply threaded to receive a wire-engaging hook 32. The hook could, of course, be welded or otherwise secured to the plug.
I claim as my invention:
1. An electrical connector comprising a tubular body having one end partly closed by a bushing through which a cable conductor may extend, a screw-threaded bushing secured in the other end of the tube, a screw plug removably engaging the latter bushing, means carried by the plug, for detachably engaging an electrical conductor, a fuse-holding clip carried by the inner end of the plug, a screw-threaded coupling socket of smaller external diameter than the screwthreaded bushing, having abutting engagement with the inner edge of the first-named bushing and having a hole through its end wall, through which wires from the cable may extend, and a coupling plug having threaded engagement with the coupling socket and having a fuse-holding clip, and a fuse carried by the clips, the coupling plug serving to clamp wires against an inner wall surface of the coupling socket, and the coupling members being removable from the tubular body, when the first-named plug is removed.
2. An electrical connector comprising a tubular body having one and partly closed by a bushing through which a cable conductor may extend, a
4 screw-threaded bushing secured in the other end or the tube. a screw plug removably 8 8 8 8 the latter bushing, means carried by the plug, tor detachably engaging an electrical conductor, a ruse-holding clip carried by the inner end of the Phil, a screw-threaded coupling socket of smaller external diameter than the screw-threaded buahins. having abutting engagement with the inner edge 0! the first-named bushing and having a hole through its end wall, through which wires from the cable may extend, a coupling plug having threaded engagement with the coupling socket and having a ruse-holding clip, a (use carried by the clips, the coupling plug serving to clamp wires against an inner wall surface of the coupling socket and the coupling members being removable from the tubular body, when the firstnamed plug is removed, and a stud on the cou- 1 8 9 1 8. in position to extend into and partly fill the hole in the coupling socket.
