A solid ring-conductor assemblage (20) blocks water from migrating in the axial direction of an electrical stranded conductor (1). The solid ring-conductor assemblage (20) has a ring and an electrical stranded conductor. The diameter of an initial opening of the ring exceeds an outer diameter of the stranded conductor (1). The solid ring-conductor assemblage (20) is obtained by the process of placing the ring in an installed position where the electrical stranded conductor (1) runs through the initial opening. A compressive force (F) is applied onto the ring (2) in the installed position thereby compressing the ring (2) as well as the portion of the electrical stranded conductor (1) as covered by the ring into a compressed state. The compressed ring and the compressed portion of the electrical stranded conductor bonds as an entity providing the solid ring-conductor assemblage (20). A ring is provided to obtain the solid ring-conductor assemblage; a cable has a stranded electrical conductor where at least one ring is compressed around the electrical stranded conductor; and a method includes manufacturing an electrical stranded conductor arranged with at least one solid ring-conductor assemblage.

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 electrical connector includes a locking unit and a contact insert at least partially surrounded by the locking unit. At least one contact is arranged in and/or on the contact insert. The contact insert is formed from a contact body and a contact sleeve connected to the contact body. Furthermore, a contact insert and a method for producing an electrical connector are described.

A break-off bolt for securing a conductor within a connector includes a first thread section, a second thread section and a torque-limiting section arranged between the first thread section and the second thread section. The first thread section and the second thread section comprise the same external thread having a minor diameter. The torque-limiting section has at least one of no thread with an outer diameter larger than the minor diameter of the external thread or an external thread having a minor diameter larger than the minor diameter of the external thread of the first and second thread sections.

A grounding clip for fastening and electrically contacting two cables to a separate surface includes a plate having a first and second longitudinal edges opposite each other and extending in a first direction, and first and second transverse edges opposite each other and extending perpendicularly to the longitudinal edges in a second direction. First and second cable fastening regions for fastening and electrically contacting first and second cables to the plate extends along the first and second transverse edges, respectively. An opening is arranged between the cable fastening regions for inserting a fastener. First and second tabs extend between the first and second cable fastening regions in parallel to the first and second transverse edges, respectively, and perpendicularly to a plane of the plate in a direction of an underside of the plate.

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.

The present disclosure describes a power cable connector. The connector includes a main body having a bore therethrough, a first threaded section, and a second threaded section; a back cover having a third threaded section configured engage the first threaded section of the main body; a pair of female conductor pins configured to be coupled to inner conductors of a power cable; an insulator having one or more recesses extending along an outer surface and a fourth threaded section configured to engage with the second threaded section of the main body, the insulator having a pair of inner channels extending therethrough sized to receive the pair of female conductor pins; an end cap including one or more recesses; and a locking nut including one or more protrusions extending radially inward. When the locking nut is inserted onto the insulator and end cap, the one or more recesses of the insulator and one or more recesses of the end cap are configured to receive and guide the one or more protrusions of the locking nut to secure the end cap to the insulator. Connector assemblies are also described herein.

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 connector for a strip of linear lighting includes an outer shell or block and an adapter configured to be removably inserted into a cavity of the outer shell. The adapter may be a printed circuit board (PCB) adapted to mount wires on one side or edge. On the opposite side or edge, a series of contact pins are formed on the underside of the adapter. The outer shell includes a pressure-applying mechanism, like screws that insert through its thickness and are secured in a bar with threaded holes. The adapter is positioned such that the screws bear on and supply pressure to the contact pins. A strip of linear lighting is inserted into a slot beneath the adapter such that the contact pins of the adapter coincide with the solder pads or other electrical contacts of the strip of linear lighting.
