Abstract: An electrical connector for a threaded stud may include: a connector body having a first end with a recessed portion and an anti-rotation wall extending upwardly from the recessed portion; a connector element configured to electrically connect and secure the threaded stud thereto; and a fastener configured to secure said connector element to the connector body. The connector element is selectively attached to the connector body in either a right-hand configuration, in which the threaded stud is secured on a right side of the connector body, or a left-hand configuration, in which the threaded stud is secured on a left side of the connector body. The anti-rotation wall engages a side wall of the connector element to prevent the connector element from rotating about the fastener relative to the connector body.

Abstract: A railroad rail is electrically and mechanically connected to a power conductor by an electrical connector that includes a first connector part having a first tail that is bolted to the web of the railroad rail, a socket, and a first opening in the socket. The connector also includes a second connector part having a second tail, a head rotatably received in the socket, and a second opening in the head. The second connector part is rotatable in the socket between an open position, in which the first and second openings are aligned to allow a power conductor to be inserted into the connector, and a clamped position, in which the first and second openings are partially misaligned to clamp the electrical conductor in place. A fastener passes through the first and second tails to hold the second connector part in the clamped position.

Abstract: An electrical connector for a threaded shaft includes first and second connector elements, each defining a respective partial-cylindrical threaded surface, a respective hinge element, and a respective tail. The hinge elements are coupled together at a hinge axis such that the connector elements rotate about the hinge axis to move the threaded surfaces toward and away from one another. The threaded surfaces are oriented to contact and intermesh with opposed sides of a threaded shaft, and a fastener holds the tails together to clamp the threaded shaft between the threaded surfaces. A third connector element cooperates with the first connector element to clamp against and establish electrical contact with a cable.

Abstract: A cable-clamping device includes a second part that is mounted for rotation in a first part. The first part defines a cable-receiving opening, and the second part defines a cable-receiving bore. The opening and the bore define opposed cable-clamping surfaces that clamp a cable therebetween as the second part is rotated in the first part to a closed position. The second cable-clamping surface of the second part is provided with a chamfer that blunts the second cable-clamping surface to reduce any tendency of the clamping device to cut into the clamped cable, while simultaneously enhancing the pull-out resistance.

Abstract: An electrical connector (10) includes inner and outer conductive straps (14, 12), each having a tail (18, 24) and a conductor-receiving portion (26, 20). The conductor-receiving portions (26, 20) are wrapped in reverse directions with respect to the axis of rotation (A) of the connector to reduce any tendency of the inner element to bind or stick in the outer element. The connector includes conductor receiving passages or openings (30, 32) for both a larger conductor such as a ground rod (C1) and a smaller conductor such as a ground wire (C2). The conductor receiving openings are oval for the ground rod and circular for the ground wire such that the connector distorts the ground wire to a greater extent than it distorts the ground rod as the connector is closed.

Abstract: A ground rod connector includes first and second connector portions that are pivotably mounted together to move between an open position and a closed position. The connector portions include tail portions that are positioned adjacent one another in side-by-side orientation when the connector portions are in the closed position, and a threaded fastener is coupled between the tail portions to hold the connector portions in the closed position. The connector portions cooperate to form a ground rod receiving passage and at least one ground wire receiving passage. These passages are formed in part by the first connector portion and in part by the second connector portion and are oriented such that movement of the connector portions to the closed position clamps a ground rod and a ground wire in the respective passages.

Abstract: A cable clamp includes first and second jaws secured together by a fastener to clamp a cable therebetween. A shield member is mounted to the longer of the jaws, adjacent to the shorter of the jaws, and a moisture resistant cover is sealed to the shield member, around the shorter jaw and to a clamped cable. The fastener includes a boss with a threaded opening on one of the jaws, which boss is received by an opening in the other of the jaws. A bolt engages the threaded opening to clamp the jaws on the cable.

Abstract: A cable clamp includes first and second jaws, each having a respective cable clamping portion and tail. The first jaw is pivotably mounted to the second jaw to move between a cable receiving open position, in which a cable can be inserted between the cable clamping portions, and a cable clamping closed position, in which the cable is clamped between the cable clamping portions. A first opening is formed in one of the tails, and a raised boss is formed on the other of the tails. This raised boss is positioned to fit within the first opening when the jaws are in the closed position, and the raised boss includes a threaded opening. A threaded fastener is mounted in the threaded opening, and this threaded fastener applies closing forces on the tails as the threaded fastener is rotated into the threaded opening, thereby moving the jaws to the closed position.

Abstract: A cable clamping device includes a female clamping member that includes a C-shaped head receiving portion and a tail. A male clamping member includes a cylindrical head positioned to rotate inside the head receiving portion of the female clamping member, and a radially extending tail. The free ends of the two tails define a total of four opposed surfaces, and these four opposed surfaces are parallel to one another when the two tails are clamped together. The lower side of the female clamping member defines a mounting plane, and the head receiving portion of the female clamping member extends both above and below the mounting plane. In this way, headroom requirements for the cable clamping device are reduced, and shorter fasteners can be used to secure the device in place.

Abstract: An improved cable clamping device includes a J-shaped female member which pivotably receives the head of a male clamping member. The male member defines a bore and a window extending through the tail of the member adjacent to the bore. This window is provided with a width greater than that of the bore. The female clamping member defines a raised clamping surface situated within the window when the connector is closed. This raised surface is provided with a flat, ridged contour and cooperates with the window to cause the free end of the cable to be spread laterally as the connector is closed. This lateral spreading increases pull-out resistance. Additionally, the connector is configured to ensure that two pairs of opposed clamping surfaces are provided, and that the clamping surfaces in each pair are axially spaced from one another ensuring a crimping rather than a pinching action.

Abstract: A cable clamping device of the rotary jaw type, including a hook-shaped female member adapted to be mounted on a support, and a male member of symmetrical cross-section with a cylindrical head adapted for rotation within the female hook. Cable-receiving bores in the male and female members and a separate clamping surface on the female shank cooperate to clamp the cable. Size or force adjustability is provided by making the axis of the male bore non-coincident with the axis of symmetry of the male member, and rotating the latter about its axis of symmetry. Cam-locking means are provided to create a resilient clamping pressure on the cable prior to closure, and to ensure positive locking of the device upon complete closure.
