UTILITY MIDSPAN ADAPTER FIELD OF THE INVENTION The invention relates to an adapter for tapping a plurality of transmission lines and a streetlight to a main electrical line span at any point thereof.
According to the present invention, the adapter comprises a stamped and formed conductor provided with a main leg and two sets of secondary legs, all of which legs are coined to a cylindrical configuration and in conformity with selected standardized wire gauge sizes. A layer of insulation is provided over the adapter. In use, insulation is stripped from selected legs. The main leg is spliced to a transmission line span at any point thereof. The secondary legs are manually bent to project generally laterally of the adapter and are spliced to taplines. A generally centrally located secondary leg is partially wrapped around the transmission line, thereby anchoring the adapter thereto at a location generally remote from its point of splice. The protruding end of the wrapped leg provides a tap on which a streetlight may be electrically attached.
OBJECTS OF THE INVENTION It is therefore an object of the present invention to provide an adapter for tapping a plurality of transmission lines to a main electrical transmission line span at any point thereof.
Another object of the present invention is to provide a stamped and formed conductor having a plurality of legs.
respectively spliced to transmission lines and with a main leg spliced to a main electrical transmission line span at any point thereof.
A further object of the present invention is to provide an adapter for tapping a plurality of taplines to a main electrical transmission line, wherein the adapter is spliced and anchored to the transmission line.
Still another object of the present invention is to provide an adapter for tapping a plurality of electrical transmission lines and a streetlight to a main transmission line.
Still a further object of the present invention is to tap a plurality of transmission lines to any point of a main electrical transmission line span by an adapter which is spliced and anchored to the transmission line and'provided with a tap on which a streetlight may be attached.
Other objects and many attendant advantages of the present invention will become apparent upon perusal of the following detailed description of the preferred embodiment taken in conjunction with the drawings.
BRIEF DESCRIPTION OF THE DRAWING FIG. I is a fragmentary perspective of an adapter according to the present invention, spliced and anchored to a main transmission line, and having a plurality of legs respectively spliced to electrical taplines, with a leg anchored to the transmission line at a point remote from the location of splice and providing a protruding tap on which a streetlight may be attached;
FIG. 2 is a perspective of the adapter according to the embodiment of FIG. 1 which has been stamped from sheet stock to form a plurality of legs, which legs are coined to cylindrical configurations in conformity with standardized wire gauge sizes; and
FIG. 3 is a perspective of the adapter shown in FIG. 2 provided thereover with a layer of insulation material.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS With more particular reference to the drawings, there is illustrated generally at l, a utility midspan adapter according to the present invention. The adapter includes a pair of spaced connector blocks 2 and 3, each in the form of a threebranched fork defined between a pair of parallel lateral planar sidewalls 4. Immediately adjacent to the sidewalls 4 are a'pair of rectangular sidewalls 6 converging to form a tapered configuration. A main, generally central longitudinal main leg 8 extends from the converging sidewalls 6 and is provided at its terminal end thereof with a generally rectangular portion 10 having a terminal planar end wall 12. The branches of the block 2 are each provided thereon with parallel longitudinal legs 14. The central one of the legs 14 additionally is connected to and projects from the converging walls 6 of the block 3. The three branches of the block 3 are respectively provided with legs 16 and 18 provided respectively with terminal end portions 20.
The entire adapter 1 is advantageously stamped from a single piece of conducting material, for example, dimensioned laterally by the walls 4 and longitudinally between the endwalls 12 and 20. Initially the stamped legs 8, 1'4, 16 and 18 may be formed with rectangular configurations as exemplified by the rectangular portion 10 on the leg 8. Subsequent to stamping, the legs are coined to the illustrated cylindrical configurations and in conformity with standardized wire gauge sizes. For example, the leg 8 may be coined to a 2/0 solid diameter of 0.364 inch to have the current carrying capacity of a 2/0 AWG, AAAC or AAC conductor. The legs 14 and 16 may be coined to the same 2/0 solid equivalent conductor. The leg 18 may be advantageously coined to a No. 4 AWG conductor equivalent which is of smaller diameter than the other legs as shown in the drawing.
With reference to FIG. 3, the adapter I is then provided thereover with a surrounding coating or layer of insulation, generally indicated at 22, completely covering the blocks 2 and 3 and each of the legs l4, l6 and 18. The insulation layer terminates in an integral sleeve portion 24 which encircles and partially extends over the leg 8. Accordingly, a substantial length of the leg 8 which protrudes from the sleeve 24 is not insulated.
In use, reference will be made to FIG. 1. The uninsulated main leg 8 is electrically tapped to a main electrical transmission line span, a portion of which is indicated at 26 by a suitable connector 28. The connector 28 is of the AMP-PACT wedge-type manufactured by AMP lnc., Harrisburg, Pennsylvania, and connects the adapter 1 underneath and generally parallel to the line span 26. Selective ones of the legs 14 and 16 may be manually bent from the positions shown in FIG. 2 to positions generally laterally extending from the adapteras shown in FIG. 1. The insulation layer covering the legs may be partially stripped off as shown at 30 to expose a protruding end portion of the legs 14 and 16. Such protruding and thus uninsulated end portions of the leg are spliced to electrical tap lines 32 by suitable electrical connectors 28', which connectors are similar to the connector 28.
With reference yet to FIG. I, the insulated leg l8, being of relatively smaller diameter is readily manually looped or partially wrapped over the transmission line 26 thus anchoring the adapter 1 to the transmission line 26 at a point remote from the location of the splice connection 28. Accordingly, the adapter 1 is suspended by the connector 28 and the leg 18 from the transmission line span 26. A portion of the insulation layer covering the leg 18 is partially stripped off as shown at 34 to expose a protruding uninsulated portion of the leg 18. The exposed portion is advantageously connected to a hanging-type streetlight (not shown).
Thus what has been described is a utility midspan adapter for connecting a plurality of taplines to a main electrical transmission line span at any point thereof. Additionally, the adapter is anchored to the transmission line span at a point remote from the location of the splice and provided with a protruding connector leg 18 to which a streetlight may be electrically connected.
Other modifications and embodiments of the invention are to be covered by the scope of the appended claims.
