ELECTRIC CONNECTION.
Specification of Letters Patent;
Patented Apr. 4., 1916.
Application filed November 7, 1914. Serial No. 870,733.
trical connection whereby an insulated elec-' tric wire or cable is detachablv connected to a binding post or other terminal for the passage of an electric current therethrough, the joint being entirely enveloped and protected by insulating material.
In my improved connection a screw cap of insulating material is slipped on to the end of the cable, the wire extending from the end of the cable is connected to the binding post in a manner to be hereinafter described. and the cap is screwed into place on the binding post support, the arrangement being such that the electric terminals will be clamped together in such relation as to insure the best possible electric conduit, and at the same time lock the end of the cable securely in the joint. This is accomplished without the small screws usually used in the connection of wires to terminals, thus avoiding the inconvenience accompanying the use of such screws. making a more positive connection, and effecting a saving of time in making or breaking connections.
In the preferred form of the invention, the construction and arrangement are such that the cable may turn freely relatively to the fixed binding post support without atfecting the electric connection; it being, therefore, a matter of indifference whether, in screwing or unscrewing the screw cap, the cable turns with it.
Another advantage of the invention is that it is impossible, bv pulling upon the cable, to disrupt or affect the electric connection.
Having now set forth in a general way the primary objects and advantages of my invention, I will describe same in detail in connection with the accompanying draw ings. in which- Figures 1 and 2 are sectional views showing steps in the process of forming a connection with my improved device. Fig. 3
is a similar View of the finished joint. Fig. I is a developed view of an intermediate link of the joint. Fig. 5 is a perspective view of said link. Fig. 6 is a sectional view showing a modification in structure. Figs. 7 and 8 are sectional views, corresponding to Fig. 2, of a modification, the two views being taken at right angles to each other. Fig. 9 is a plan view of the binding post of Figs. 7 and 8.. Fig. 10 is a plan view of a binding post of still another modification. Fig. 11 is a sectional view of the finished joint of Figs. 7 and 8, but somewhat modified in construction.
Asshown in Figs. 1. 2 and 3, the stationary terminal member comprises a binding post a and support Z), the former being turned down as it emerges from its support to form a projection c. -An intermediate link (l is stamped out of a thin strip of conducting material as shown in Fig. 4. This link is bent around into the ring form shown in Fig. 5, the two end holes 6 overlapping. 'This link is then slipped over the projecting end 0 of the binding post and held. loosely thereon bv cotter pin f.
The end of the insulated wire 9 is scraped free of insulation as shown at h, and the cap 2' of insulating material is strung over the wire it onto the insulated portion. The bare wire it is then passed through holes in link (Z, as shown in Fig. 1. The bare wire is then pulled farther through the link and wound about itself as shown in Fig. 2.
Next the cap 2' is slid down and screwed onto the su port I). the recess 7c in said cap being of suliicient depth to compress the link (Z down upon the projection c, as shown in Fig. 3.
In connections of this form the orifice in the cap is necessarily made a close fit on the insulated wire, in order to provide bearing and support for same. Therefore. in the ordinarv construction, when screwing the cap into this form of connection, the wiretherein is apt to be turned with the screwing moti n, tending to impair or destroy the electric connecti n of the wire to binding post. In the embodiment of my invention just described. the link (Z is swiveled upon the binding post and is readily turn-able thereon, allowing the turning of the end of the wire with the screwing on of the cap without in wire passing through them when bent into" the shape shown in 8. Further the narrowing of the link between holes 6 and j prorides for flattening the link withontidis torticn of the central part thereof. If the cap is not made to fit tightly over the insulated wire as stated, it does not only not term a good support for said wire, but in allowing the cap to be turned in relation thereto in the process of screwing into place, the opening in the cap tends to wear and abrade the insulation on the wire. The ori ice in my imorored cap holds the wireipas'sing therethmugh firmly, and by being slightly rounded at m, allows free bending of the wire withont danger of cutting the insulation.
A. modified form of structure is shown in Fig. 6. In this case, the connection is made exactly as described above, but the members in threaded en 'age'ment are here made of metal instead of the hard rubber or other composition used for a non-conductor. The cap 2" has cast therein the threaded metal ring Z. Similarly the threaded part at is made of metal, in one piece with the binding post a. This makes a much cheaper struc" ture. and the engaging threads, bemg of metal, are more durable and perfect thanthe.
composition threads. The embodiment of my invention shown in Sheet 2 of the drawings does not possess all the advantages of the embodiment shown on Sheet 1, in that the intermediate link, while swiveled upon the binding post has no unlimited turning movement thereon; but the structure" is available for use where it is desired to estab lish a plurality of electrical connections with a plurality of binding posts. and is especially applicable to electric light sockets. In this contraction, 6 represents the support for the two fixed binding posts aihaving the projecting ends 0 The two intermediate links (Z are applied to the ends 0 of the binding posts a as hereinbe'fore described.
The' two ends of insulated wire g h'ave sleeved upon them the cap 2' and theirbare ends 71 are respectively secured to the two intermediate links (P, as hereinbefore de scribed. A partition 0' extends upward from the support a and has a relatively narrow projection 79 having a J-shaped recess in its upper end, thus allowing the wires h to extend on opposite sides of the partition and projection, which maintain the wires insu lated from each other. When the cap 2' is slid down aii'cl screwed onto the support b the partition 0 extends up into the recess k within'the cap, the projection pennies up into" the cable-receiving orifice iii the cap, antltlie links d are compresseddownupon the projections 0 as shown in Fig. 11, the two ba're'ends of wire h extending respecti'y'ely on opposite sides of the partition 0 and projection p. In the last named figure, however, the construction differs somewhat from that shown in Figs. 7 and 8, in that the base 0 has a screw threaded orifice to receive the special fitting r carrying the two binding posts a".
InnFig; 10 I haveindica't'ed' how the invention may be" adapted to three or more electrical connections by forming on thesiip port three or more partitions' s adapted to separate from each'other the separate wires.
The various modifications shown are merely illustrativeof thepossibility of varying the mechanical details without departingilfrom the essential invention;
avingnow fully described my invention,
