Apparatus for making electrically conductive contact with an electrically conductive, elongated, body, for example a pipe or cable. Apparatus includes a base body having a metal carrier element configured as a clamp clampable around body to be contacted, and open in circumferential direction. Apparatus includes a connecting device with a connecting member, by which ends of carrier element are connectable or connected to one another when mounted. Apparatus has a contact device for establishing electrically conductive connection between body contacted and conductor, such as grounding cable. A connecting member configured for cooperating with a guide device for guiding translatory motion of connecting member, and situated at free ends of carrier element so that in mounted position of apparatus, translatory motion of the connecting member between a guide start and a guide end of guide device achieves a nondestructively detachable form fit, connecting free ends of the carrier element.

A swivel joint includes a tail section and a body portion that define a passageway therethrough and which can rotate relative to one another. One or more seals and bearings can be disposed between the tail section and the body portion. An electrical conductivity grease fitting can be mounted within a bore hole in the body portion. The electrical conductivity grease fitting can have a lubricant passed therethrough to lubricate the bearings. The electrical conductivity grease fitting has a first portion in electrical communication with the body portion and a second portion that is biased into electrical communication with the tail section to maintain electrical conductivity between the tail section and the body portion.

An equipotential bonding system can be provided for a lightning protection system that includes a mast assembly with an internal passageway that includes an internal surface, and a conductor that extends through the internal passageway. The equipotential bonding system can include a deflection member that is disposed at least partly within the internal passageway. The deflection member can be configured to urge the conductor into contact with the internal surface to form a conductive pathway between the mast assembly and the conductor.

An irrigation system grounding strap including an adjustable lap-joint band clamp attachable to a wheel support lateral member of an irrigation system end tower with a flat braided copper wire strap having one end attached to the band clamp and an opposite end having a ground body, such as a flat washer, attached thereto that makes ground contact when the irrigation system is operating to dissipate electrical charges produced by a short circuit in the electric drive motor on a lateral wheel support member of an end tower of the irrigation system.

A grounding pipe clamp secures a pipe and accommodates various attachment configurations to secure a range of conductor sizes. The grounding pipe clamp includes a bolt, a main body, and clamping pads. The bolt has a first leg and a second leg. The main body has a first end portion, a middle portion, and a second end portion. The first end portion has a slot that receives the first leg of the bolt. The second end portion has a L-shaped cutout that receives the second leg of the bolt to secure a pipe between the main body and the bolt. The clamping pads are secured to the first leg of the bolt and the second leg of the bolt. The clamping pads secure the conductors positioned on the main body.

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.

A mechanical grounding clamp including a body, having an upper plate defining a threaded hole therethrough and having an outer surface, a lower plate spaced apart from the upper plate and having an inner surface, and a connecting plate connecting the upper plate to the lower plate, a fastener mateable with the threaded hole in the upper plate and having a proximal end and a distal end, the distal end extendable through the threaded hole of the upper plate and toward the inner surface of the lower plate. There may be a nut on the fastener for driving toward the upper plate to secure a grounding conductor to the body.

A connector assembly for earth-bonding of a corrugated stainless steel tubing system is disclosed. The collector assembly incorporates a fitting to hold a tubing at least at one opening of the fitting, a collet at inner side of the at least one opening to enable sealing of the tubing, and a nut configured on outer side of the one or more opening of the fitting. The connector assembly can include one or more holes positioned at pre-defined positions on the fitting or nut to electrically couple one or more earth-bonding means at the one or more holes. The earthing means can include an earthing cable coupled to the fitting or the nut by an earth-bonding clamp or a tightening screw, which can be connected to an electrical earth or electric zero potential for providing earth-bonding.

A mechanical grounding clamp includes a body, having an upper plate defining a threaded hole therethrough and having an outer surface, a lower plate spaced apart from the upper plate and having an inner surface, and a connecting plate connecting the upper plate to the lower plate, a set screw mateable with the threaded hole in the upper plate and having a proximal end and a distal end, the distal end extendable through the threaded hole of the upper plate and toward the inner surface of the lower plate. There may be a nut on the set screw for driving toward the upper plate to secure a grounding conductor to the body.

A press coupler is provided for use with a pipe or conduit system. The press coupler facilitates increased ease and speed of assembly of pipe and conduit installations and can be used with both threaded and non-threaded connections.
