The numeral 26 merely designates a washer which is interposed between the inner end of the contracting sleeve and the adjacent apertured eye I3, 7

In assembling the structure the spear-like or :10 pointed head I8 is forced into the wire core I5 Then, the bushing I9 is threaded into place to take the position shown in Figure 2. Then the contraction sleeve 25 is slipped up over the bushing and stud and as it is forced outwardly or longitudinally from right to left in Figure 2 it binds the fingers 20 tightly in order to effect a permanent connection between the stud I1 and the wire core I5. The extreme right hand portion of the stud extends through and beyond the eyes I3 to accommodate the nut 2 and the nut serves not only to speed the sleeve 23 into binding position but simultaneously serves to secure the clamp I I on the battery post I 0.

Attention is now invited to Figures 5 and 6 showing a modification of the invention. The battery, post, and clamp are designated by the same reference characters already utilized in Figures 1 and 2. The cable is distinguished by the numeral 23 and comprises a wire core 21 and an insulation covering or casing 28. In this arrangement the terminal is adapted to be built into the cable at the time of manufacture. This result is satisfactorily accomplished by using a different type bushing 29. As shown in Figure 7 this comprises a neck or collar 30 internally screw threaded as indicated at 3i and an integral sleeve 32 of appropriate taper. A substantially T-shaped slot comprising a longitudinal main slot 33 and a short transverse head slot 34 is provided here. The spear head 34 on the screw threaded stud 35 is forced into the wire core and threaded through the collar as shown in the assembly in 45 Figure 6. The bushing 29 is slipped over the core and is tightly clenched in place to join the stud and core together in permanent relationship. The entire sleeve or bushing 23 is here covered with the insulation covering 28. The numeral 36 merely designates a stop nut on the stud located adjacent one of the apertured eyes I3 as shown in Figure 6 so that the take-up action of the nut 24 does not effect the coupling of the stud to the core. As before stated, in this arrangement, the stud is already built into the cable at the time of manufacture.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size, and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.

I claim:

1. In a structure of the class described, a conductor cable embodying a wire core and an insulation covering therefor, the covering terminating short of one end of the core, a screw threaded stud having a pointed head embedded in said projecting end of the core, a tapered longitudinally slit bushing having a screw threaded collar at one end, said collar being threaded on the stud into abutting relationship with the core, a frusto-conical binding sleeve fitting over said collar and slitted portion of the bushing, together with a split ring post clamp having apertured eyes, the free end portion of the stud extending through and beyond the eyes, and a nut on the extreme outer end of said stud, said nut serving to simultaneously move the eyes toward each other to secure the clamp in place and at the same time to longitudinally adjust said bushing relative to said sleeve to bind the bushing firmly into clamping contact with said core.

2. A cable terminal, comprising a screw threaded stud adapted to be arranged in abutting relationship with the cable, a tapered, longitudinally slit bushing having a screw threaded collar at one end, said collar being threaded on said stud with said bushing embracing said cable, a tapered binding sleeve fitting over the collar and slitted portion of said bushing, together with an apertured support, the free end of said stud extending through and beyond said aperture, and a nut on the free end of said stud, the tightening of said nut serving to clamp said support between said nut and sleeve and at the same time to longitudinally adjust said sleeve relative to said bushing to bind the bushing firmly into clamping contact with said cable.

3. A cable terminal comprising, a screw threaded stud having a pointed head embedded in the end of the cable, a tapered longitudinally slit bushing having a screw threaded collar at one end, said collar being threaded on the stud, a tapered binding sleeve fitting over said collar and slitted portion of the bushing, together with a split ring post clamp having apertured eyes, the free end portion of the stud extending through and beyond the eyes, and a nut on the extreme outer end of said stud, said nut serving to simultaneously move the eyes toward each other to secure the clamp in place and at the same time to longitudinally adjust said bushing relative to said sleeve to bind the bushing firmly into clamping contact with said cable.
