A cable connector assembly includes a pair of sub-assemblies movable in translation relative to each other along a clamping direction and a tightening device tightening the sub-assemblies along the clamping direction. Each of the sub-assemblies is pivotable relative to a pivot axis extending perpendicular to the clamping direction. Each of the sub-assemblies has a main housing and a clamping part at least partially housed within the main housing. The clamping part is movable in translation relative to the main housing along the clamping direction. The tightening device tightens the sub-assemblies along the clamping direction with a first clamping region formed between the sub-assemblies that receives and clamps a first cable. A secondary clamping region is formed in each of the sub-assemblies between the clamping part and the main housing that receives and clamps a secondary cable.

A clamping assembly for attaching a grounding conductor to a pipe having a protective coating includes an elongate conductive strap and a clamp. The conductive strap is sufficiently long to circumferentially surround the pipe and has longitudinally spaced sharp projections that are sufficient to penetrate the protective coating around the pipe to make an electrical coupling between the strap and a conductive part of the pipe beneath the protective coating. The clamp is coupled to the grounding conductor and clamps the conductive strap to the pipe at a tension sufficient to maintain an electrical connection between the conductive part of the pipe and the grounding conductor without the need for any welding of the grounding conductor to the pipe and without the need for any stripping of the protective coating from the pipe.

An insulation piercing connector includes a connector body, a bolt, a piercing pin, and an insulator member that electrically insulates the piercing pin from the bolt. The connector body includes a cable receiving slot and a threaded bore in communication with the cable receiving slot. The bolt includes a threaded shank with a central bore, and a head joined to the threaded shank by a shear-off section. The piercing pin is supported within the central bore by the insulator member and includes opposite first and second ends. The first end is configured to pierce the insulation of an electrical cable extending through the cable receiving slot and contact a conductor. The central bore of the bolt threadingly receives a sensor. The sensor includes a probe that contacts the second end of the piercing pin to obtain information from the conductor, such as voltage, current, and/or thermal information.

Various implementations of insulation piercing connectors are disclosed. The insulation piercing connectors include a simple and efficient design for providing electrical tap connections to a power cable for voltage detection purposes. The insulation piercing connector includes at least a top housing and a bottom housing that come together to receive the power cable. Terminal contacts are housed internally within the insulation piercing connector, and the terminal contacts are positioned to pierce the power cable when the insulation piercing connector is assembled into an operational state.

A novel cable connector comprises a main body, a clamp, a conductor assembly, and a controller. The main body is provided with an installation cavity and a receiving slot, and both sides of the receiving slot extend longitudinally to form a left and right wing. The clamp is arranged in the receiving slot, the receiving slot forming a passage for accommodating a cable. The conductor assembly is arranged on the installation cavity of the main body, and comprises a sharp lower end, which protrudes from the top surface of the receiving slot and is located in the passage. The clamp is located between the controller and the main body, the controller cooperates with the left wing and the right wing under an external force to directly apply a force to the clamp to drive the clamp to move towards the top surface of the receiving slot.

The present invention concerns a line filter (1), which is configured to be installed onto a system cable (2), wherein the line filter (1) comprises a magnetic component (4), wherein the line filter (1) defines a cable path (6) through the line filter (1), wherein the line filter (1) is configured to allow a placement of the system cable (2) along the cable path (6) at the time of an installation, thereby providing a magnetic coupling of the system cable (2) to the magnetic component (4), and wherein the line filter (1) comprises an insulation displacement connector (16) and a shunt component (5) wherein the insulation displacement connector (16) is configured to be tightened at the time of the installation, thereby providing a galvanic connection of the system cable (2) to the shunt component (5). Further, the present invention concerns a method of installing a line filter (1) onto a system cable (2).
