A break-away hook assembly is adapted for installation for use with a low-voltage residential communication cable. A pair of members is coupled. One of the members has a connector with a terminal portion which receives a terminus of the other member. The connector breaks to release the second member from coupled engagement with the first member so that upon application of a stress in excess of a pre-established load, the cable will sag while maintaining the communication integrity of the cable.

Break-away hook assembly

A ground connector implemented as a modified lug on a flexible ground lead allows the convenient termination of a solid ground wire at a cable shield ground clamp. The ground wire and ground clamp are electrically and mechanically attached at the modified lug. The flexible ground lead carries the combined ground connection to a common ground point within an enclosure.

Ground connector

Electrical clamp connector

An electrical clamp connector for clamping ground conductors employs interconnecting male and female clamp sections having integrally extending jaws. The male clamp section forms a tongue which is received in a complementary groove defined by the female clamp section. The jaws include V-shaped holding surfaces and a retaining lip which allow the clamping of conductors of various sizes. The clamp sections are fastened together by a bolt passing through the female clamp section to threadably engage the male clamp section whereby the jaws are drawn together, clamping conductors received therein.

A flexible bond harness including a flexible ground subassembly and a rigid ground subassembly which are joined together by a barrel connector. The flexible ground assembly has a first terminal connector which is mounted to the distal end portion of a substantially flexible conductor and the rigid ground assembly has a second terminal connector which is mounted to the distal end portion of a substantially rigid conductor. The barrel connector has a substantially uniform thickness, first and second side walls, a base and is divided into first and second segments. The proximal end portion of the flexible conductor is positioned within the first segment and the proximal end portion of the rigid conductor is positioned within the second segment. The first and second segments of the barrel connector are simultaneously crimped onto the flexible and rigid conductors, respectively, forming a bond which prevents relative motion between the barrel connector and the flexible and rigid conductors.

Flexible bond harness and manufacturing method therefor

A mast clamp assembly including a strap, a drop wire clamp, and a hook. The ribbon-like strap forms a loop which engages a utility pole or mast. The drop wire clamp includes a clamp for clamping to the drop wire and a loop which engages the hook. The hook includes a back wall and first and second side walls. The loop of the drop wire is received in loop mounting slots in the side walls and engages a protrusion on each side wall. Each side wall also has a strap mounting opening having a triangular-shaped lower portion and a rectangular-shaped upper portion. The hook is mounted on the strap by inserting the strap, bottom edge first, through a slot in the back wall into the lower portion of the strap mounting openings and rotating the hook around the strap such that the upper edge of the strap rotates into the upper portion of the strap mounting opening and the strap engages the hook back wall.

A ground clamp for clamping to a cable shield to provide a ground connection employs a yoke member having a U-shaped yoke section, a rigid ground section and a strain relief section. The yoke member is molded as an integral unit, eliminating all machining/stamping operations from its manufacture. A relatively inexpensive zinc alloy is used in the manufacture of the yoke member, eliminating the use of relatively expensive bronze and copper. A keeper has a driver which threadably engages thread surfaces at the interior side of the yoke legs. The keeper has a clamp jaw which may be compressively engaged against a cable shield received in an aperture defined by the yoke. Electrical tape, tie-wraps, or similar devices mechanically connect the strain relief section of the yoke member to the cable outer jacket to relieve strain on the cable conductive sheath.

A connector for clamping to a cable shield to provide a ground connection employs a U-shaped yoke. A keeper threadably engages thread surfaces at the interior side of the yoke legs. A clamp jaw on the keeper is compressively engaged against a cable shield received in an aperture defined by the yoke. The yoke connects to a flexible ground wire via a spark gap assembly. An electrically conductive boss extends from the yoke into one end of a bore in an electrically non-conductive separator member. The ground wire is mounted to the separator member by an electrically conductive fastener that extends into the other end of the bore of the separator member. The distal ends of the boss and the fastener are separated by a spark gap. The distal end of an electrically conductive bridging member is positionable in the separator member to engage the distal end portions of the boss and the fastener to bridge the spark gap and provide electrical communication therebetween.

A ground clamp for clamping to a cable shield to provide a ground connection employs a U-shaped yoke. A keeper has a driver which threadably engages thread surfaces at the interior side of the yoke legs. The keeper has a clamp jaw which may be compressively engaged against a cable shield received in an aperture defined by the yoke. A surface of the clamp jaw and a surface of the driver have complementary radially extending projections and grooves, respectively. The projections are received by the grooves when the clamp jaw engages the cable shield to resist relative movement between the driver and the clamp jaw. The yoke then connects to a common ground point via a flexible ground wire connection. A protective shoe may be inserted between the cable conductors and the clamp jaw to prevent crushing of the connectors.

Conductor protector

A ground clamp for clamping to a cable shield to provide a round connection employs a U-shaped yoke. A keeper has a driver which threadably engages thread surfaces at the interior side of the yoke legs. The keeper has a clamp jaw which may be compressively engaged against a cable shield received in an aperture defined by the yoke. The yoke connects to a common ground point via a ground connector member. The ground connector member has a grounding portion which may comprise a flexible ground connector or a rigid conductive plate. A bracing portion of the ground connector member is connected to the grounding portion by a ramp portion which projects laterally towards the cable. The bracing portion includes two arms which project laterally from a center connector portion. The connector portion and arms define a horseshoe-shaped stress relief clamp which may be crimped into engagement with the cable to mechanically connect the ground clamp with the cable outer jacket.

Cable shield ground clamp

A universal ground clamp is employed for clamping to a ground electrode such as a conduit, a pipe or a rod by means of a clamp strap. The ground wire is secured by means of a set screw in an aperture of a head which extends from a threaded shank. A platen, which has a convex bowed surface, is retained against rotation by retainer flanges of a contact member. The platen is clamped against the strap to secure the ground clamp in position. The clamp may be mounted and the ground wire secured by applying a torque from one side of the ground clamp.

Universal ground clamp

A bond clamp attaches to a T-slot of a cable rack for connecting a ground conductor. An L-shaped bolt inserted in a T-slot secures a pair of clamp members to the cable rack. The ground conductor is clamped between the clamp members to provide the electrical bond connection with the cable rack.
