A temporary grounding assembly is provided that includes a ground clamp, a tensioning member, a tensioner device, a first conductor, and a ground rod. The ground clamp has a main body with a plurality of teeth that are configured to make electrical connection with an outer diameter of a pipe. The tensioning member is secured to one end of the ground clamp. The tensioner device is securable to the tensioning member and to an opposite end of the ground clamp. The first conductor is in electrical connection with the ground clamp. The ground rod is in electrical connection with the first conductor.

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.

In at least some implementations, a retainer for a fuel system component having an electrically conductive portion accessible from the exterior of the component includes a retaining feature and a grounding feature. The retaining feature is adapted to maintain the location of the fuel system component and the grounding feature electrically couples a ground wire to the electrically conductive portion of the fuel system component. The fuel system component is grounded through a path including the grounding feature and ground wire.

This detection terminal (2) includes a fixing portion (4) intended to be fixed in a structure, an electrically conductive protective portion (5) secured to the fixing portion (4) and arranged to protect the fixing portion (4), the protective portion (5) being arranged to be accessible from the outside of the structure so as to allow the injection of an electric signal, and connection means intended to connect propagation means capable of propagating an electric signal along the optically invisible network, the connection means being connected to the protective portion (5) so as to hold, when in use, an electrical continuity between the protective portion (5) and the propagation means.

A subsea connector includes a recess arranged on an inner surface of the housing of the subsea connector. The recess is configured to receive a canted coil spring such that it provides an electrical multi-point contact between an outer shielding layer, sometimes referred to as a screen, of a subsea cable. The subsea connector further includes a link configured to releasably attach an earth link wire to the housing.

A hot stick 8 is provided for applying a grounding clamp, such as a grounding clamp 10, to an overhead electrical conductor, such as an overhead electrical conductor 12. The hot stick 8 includes an elongate insulating pole 42, an electric stepper motor 44 carried on the pole 42, and an adapter 46 mounted on the pole 42 for rotation about an axis 22, with the adapter 46 operably connected to the electric motor 44 to be rotated by the electric motor 44 about the axis 22. The adapter 46 has a receptacle 52 configured to receive a rotatable member 20 of a grounding clamp, such as a rotatable member 20 of the grounding clamp 10, and to transfer a rotational force from the electric motor 44 to the rotatable member 20 to actuate the grounding clamp 10 between an open condition and clamped condition of the grounding clamp 10.

The invention relates to an electronic arrangement (1), comprising: an electronic component (2), a cooler (3) for cooling the electronic component (2), a housing (4), and a contact element (5), wherein: the electronic component (2) and the cooler (3) are arranged within the housing (4); the cooler (3) has at least one coolant connection (31) which protrudes through a through-opening (41) in the housing (4); the contact element (5) interconnects the cooler (3) and the housing (4) in an electrically conductive manner, and the contact element (5) is designed and arranged concentrically with the through-opening (41).

The invention relates to a connection head piece for contacting an insulated down conductor in the external lightning protection, comprising a sleeve having an axially extending first inner diameter section adjusted to the outer diameter or cross-section of the insulated down conductor for receiving one end of the insulated down conductor, and having a second inner diameter section extending axially adjacent thereto and adjusted to the outer diameter or cross-section of a stripped, exposed conductor end of the insulated down conductor, and means for fastening the stripped, exposed conductor end in the second inner diameter section. According to the invention, a static friction-generating means is formed in the first inner diameter section of the sleeve and flexibly projects into the interior of the sleeve such that a nonpositive connection is established between an outer sheath of the insulated down conductor and the sleeve upon insertion of the down conductor.

An insulated grounding hub locknut for securing a conduit connector or threaded conduit has a locknut and a snap-on insulator. The outer surface of the locknut has grounding-lug mounting pads and raised members, and the inner surface has internal threads for screwing onto threads of conduit connector or a threaded end of the electrical conduit. The snap-on insulator has an annular body with an end face, the outer side of which has a cylindrical surface arranged to snap onto the raised members of the locknut. The cylindrical surface has open slots to receive the mounting pads on the locknut. The end face also has an inner cylindrical sleeve arranged to be placed inside the throat of the first cylindrical member of conduit connector.
