Abstract: A basic connector body (13) which electrically connects and mechanically secures a ground wire (1) to a grounding member (14), e.g. pipe or electrical conduit, which body is made of a one piece brass alloy casting. The generally cylindrical, basic connector body has a smaller diameter, wire section and a larger diameter, pipe section, the size of the latter allowing the body to be slipped over the pipe end. In contrast, the smaller, wire section prevents the pipe from passing through the connector body due to the presence of a ridge (7). When the connector body is slipped over the end of the grounding pipe until the end of the pipe bears against the ridge, a first set screw (8) is screwed down until it drives itself down against the outer, exterior surface of the pipe, electrically connecting and mechanically securing the connector body to the pipe.

Abstract: A connector is securely mounted on the end of a low voltage track. The connector is electrically connected to a pair of spaced conductive wires in the tracks. The conductive wires are separated in an insulator body. The insulator body has a pair of opposed inwardly extending edges. The terminal includes a base having a pair of opposed resilient side walls. Each of the side walls defines in part a respective longitudinal receptacle groove. Each receptacle groove is parallel to the other groove. A cantilever tongue is formed integral with the side walls and is substantially parallel to the grooves. The tongue is positioned between the opposed edges of the insulator body. The tongue has opposed portions positioned under the inwardly extending edges of the insulator body. A connector belt is positioned in each of the receptacle grooves. Each connector belt receives a wire from the low voltage track.

Abstract: A terminal block, by means of which a multi-core cable is connected to several drop wires, may be repaired by positioning an adapter over its binding posts. The adapter has an aperture into which a non-stripped, non-split, multi-core drop wire can be inserted such that one core of the drop wire is adjacent one binding post. Caps are then screwed onto the binding posts to make contact with respective cores, prebinding posts to make contact with respective cores, preferably by cutting through insulation of the drop wire. The adapter may be adjustable to suit different sizes of terminal block.

Abstract: A clamping assembly which provides a uniform pressure simultaneously at two spaced apart points. The assembly includes a portion of a support member which has two parallel sides and a passage connecting the two parallel sides. A tubular shaped sleeve is received within the passage and includes short tabs extending slightly past the surface of the two parallel sides of the support member. A U-shaped anti-turn bracket is slidably received around the support member and includes slots that coincide with the passage in the support member. The tubular sleeve has a non-circular inside cross-section. A double-ended bolt having a first and second threaded end and an intermediate non-circular portion complementary to the non-circular cross-section of the sleeve is slidably received within the sleeve. The bolt is permitted to move linearly but not permitted to rotate within the sleeve. Threaded nuts are placed on each of the first and second threaded end.

Abstract: The present invention relates to an electrical connector for coupling together at least two electrical conductors in electrically conductive relationship to each other. The connector has an elongate hollow tubular conductive sleeve in which the conductors are inserted to be coupled. At least one radial aperture extends through the sleeve, and a fastening means extends through the aperture for fastening the conductors in the hollow tubular sleeve by pressing the conductors against the interior surface of the sleeve. An electrically insulative coating covering substantially the entire exterior surface of the sleeve eliminates the potential for electrical shock.

Abstract: A high-voltage test terminal for interconnection between high-voltage power lines and the bushing stud member of a transformer or reactor. An insulator component of the terminal is placed in compression rather than tension, the terminal having a substantially reduced moment arm to withstand angular forces which are created upon interconnection between the power lines and the stud member. Metallic end fittings for the insulator serve to maintain the insulator in permanent compression and provide ready disconnection of the bus bars of the terminal for determination of induced electrical currents such as by Doble testing. The insulator is mounted horizontally between the end fittings and between the power lines in substantially parallel and horizontal alignment therewith, and eliminates the torsional stresses which have been generated previously with upright post-type insulators.

Abstract: An electrical cable connection device (10) for use in splicing a pair of cables or teminating a single cable has been disclosed. More particularly, the device (10) includes a body member (12), wedge (14) and bolt (16). An axial passage (22) through the body member for receiving the end of the cable is intersected by a transverse passage (42) in which the wedge (14) is slidably positioned. The wedge (14) is drawn into tight engagement with the cable by the bolt (16) entering the transverse passage (42) on an opposite side of the axial passage (22).

Abstract: Improved terminal blocks having inserts comprising a spring-loaded stirrup for clamping electrical conductors, together with a screw for adjusting the clamping action of the stirrup and for releasably locking the stirrup in a fully open position to permit insertion of an electrical conductor, a mechanism for quickly and easily releasing the stirrup when the conductor is in a desired position, and an attachment member for releasably securing the block to a mounting rail.

Abstract: A conductor connector arrangement includes an elongated current bar having two end portions each of which is bent back on itself. An upwardly open elongated insulating material housing accommodates the current bar and has guiding grooves extending in the longitudinal direction of the current bar. At least one clamping body includes a clamping member and has laterally projecting guiding lugs which are introducible into the guiding grooves of the housing at a longitudinally central region of the current bar and guide the clamping body in the guiding grooves during displacement of the clamping body from the longitudinally central region into juxtaposition with the respective bent-back one end portion of the current bar for clamping an electric conductor to the bent-back end portion of the current bar and thus for electrically connecting the conductor with the current bar.

Abstract: This invention comprises a connection between a plurality of electrical conductors such as a mainline conductor and a tap or branch line conductor. The connection utilizes a connector comprising a pair of members which clampingly engage one conductor. One of the clamping members includes means for engagement with another conductor. The clamping members are smoothly contoured and free of sharp edges and all other parts are completely recessed within the clamping members when the connector is installed to prevent interference with or damage to insulation applied to the connection.
