A through roof connector assembly for connecting an air termination conductor to a conducting rod through a roof of a structure while limiting water ingress into the roof. The through roof connector assembly includes a universal top, a threaded stud, a conduit connection component with an upper threaded tap hole and a lower threaded tap hole which do not meet to provide a completely weatherproof connection, and a conduit extending through a roof membrane when installed in the roof. The conduit has within a conducting rod, the conducting rod threaded the lower threaded tap hole of the conduit connection component. The air terminal also threads into the threaded stud. An o-ring is located between the conduit connection component and the conduit to provide a further weatherproof connection.

An assembly is provided for a connector of an electrical wiring device having a base with a plurality of electrical terminals having a connecting screw. The assembly includes a plurality of terminal connector with a base extending from the first end and having a screw hole for coupling to one of the electrical terminals by a connecting screw. The leg has a screw hole receiving a coupling screw for electrically connecting a wire to the terminal connector and the terminal of the electrical wiring device. A clamping member receives the coupling screw for clamping the wire between the leg and clamping member. A cover encloses the terminal connectors and includes one or more apertures directing a wire through the cover to the terminal connector assembly to clamp the wire in place. Access openings are provided in a wall of the cover to access the coupling screws for clamping wires to the terminal connector assembly.

A battery terminal clamp has a body portion with an intermediate aperture for engaging a battery post. The clamp further includes a threaded rod extending upwardly relative to the body portion at an angle to the horizontal of between 45 and 60. A battery pull bar extends from one side wall to the opposite side wall of the body portion. A wedge-shaped element abuts one side wall of the body portion. Together with the battery pull bar, the wedge-shaped element alternately effects a reduction in, or increase in, the size of the intermediate aperture.

A circuit board disclosed herein includes a threaded receptor, one or more alignment holes, and one or more pads. The threaded receptor is configured to receive a component with a threaded screw. Each of the one or more alignment holes are configured to receive an alignment pin located on the component. Each of the one or more pads are configured to electrically connect to a pogo pin on the component.

A terminal attaching/detaching device includes a housing, an engaging member, and a movable member. The engaging member is configured to move in a first direction toward a terminal inserted in the housing to engage with the terminal, and is configured to move from the terminal inserted in the housing in a second direction to disengage from the terminal. The movable member is configured to move in concert with the engaging member in the moving process thereof in the first direction, and is configured to move the engaging member from the terminal inserted in the housing in the second direction, so that the engaging member is disengaged from the terminal.

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.

The present invention relates to mechanical connector (10, 100) for connecting an electrical cable (1) comprising a longitudinal internal bore (14) configured for receiving the electrical cable (1) and a transverse threaded hole (22, 24, 26, 28, 102) extending into the longitudinal internal bore (14). The mechanical connector (10, 100) comprises a laterally-open groove (34) recessed in an internal wall (20) along a longitudinal direction (Y) of the longitudinal internal bore (14). The groove (34) has a higher curvature value (R2) than a curvature value (R1) of the longitudinal internal bore (34), and is substantially arranged opposite to the transverse threaded hole (22, 24, 26, 28, 102). The present invention further relates to methods for manufacturing such mechanical connector (10, 100) and a method for assembling the mechanical connector (10, 100) with an electrical cable (1).

A wire connection assembly comprises a connector body and a binding screw. The connector body forms a wire receiving chamber and has a threaded bore extending perpendicular to the wire receiving chamber. The binding screw has an inner bolt and an outer bolt. The inner bolt includes an outer thread and an inner breaking point. The outer bolt includes an inner thread engaging the outer thread, a threaded section engaging the threaded bore, and an outer breaking point.
