An electrical connector is configured to couple an electrical conductor to a support surface. The electrical connector includes a terminal block having a connecting aperture and a threaded aperture. The connecting aperture is configured to receive the electrical conductor. The electrical connector also includes a fastener having threads receivable within the threaded aperture. The fastener is configured to secure the electrical conductor against movement relative to the terminal block. The electrical connector further includes a lock selectively receivable within a slot of the fastener to inhibit unintentional movement of the fastener relative to the terminal block.

In various representative aspects, the present invention relates generally to providing an apparatus for securing a solar panel module to a solar panel rail guide structure. More specifically, the invention relates to providing an end clamp that mounts a bottom flange of a solar panel module to a solar panel rail guide structure. The end clamp does not require any tools for insertion. It mechanically fastens and electrically bonds the solar panel module to a solar panel rail guide structure.

A method according to one embodiment includes securing a first plurality of conductive sheets to a surface, applying a conductive tape to a first plurality of joints between conductive sheets of the first plurality of conductive sheets, and securing a second plurality of conductive sheets to the first plurality of conductive sheets without fully penetrating the first plurality of conductive sheets. In such an embodiment, each of a second plurality of joints between conductive sheets of the second plurality of conductive sheets is offset relative to the first plurality of joints.

A ground block may include a metal ground plate and a ground wire fixedly coupled with the metal ground plate. The ground wire is configured to be non-detachable from the ground block during normal use of the ground block. The ground block may be formed by soldering, brazing, or clamping the ground wire to the metal ground plate.

A fastening system has a conditioner clamp and a penetrating fastener. The conditioner clamp has an upper assembly and a lower assembly attachable together to define a conductor cavity therebetween. At least one threaded opening provides ingress into the conductor cavity. The penetrating fastener is extendable through the at least one threaded opening. The penetrating fastener has a threaded bolt and a penetrating portion with a proximal end at a second end region of the threaded bolt and a distal end spaced therefrom. The penetrating portion has a frustoconical configuration terminating at a tip portion. The tip portion is configured to penetrate into a conductor positioned within the conductor cavity.

A busbar contact includes a contact ring and a fastening element. The contact ring has a contact surface at a distal end and a press-in flange projecting radially. The press-in flange has a cylindrical contact surface pointing radially outward.

A bolt terminal mounted on a guide rail is provided. The bolt terminal comprises a housing (1), an integral nut (2), a screw (3), a connection component (4), and a wiring metal surface (5); one end of the screw is provided in the housing, the other end of the screw is located outside the housing, and the screw located outside the housing is to be connected to the integral nut fitted therewith; the wiring metal surface is provided on the interface between the screw and the housing; and the housing is to be connected to the guide rail via the connection component. The bolt terminal increases the requirement for powering the wirings, and the bolt terminal can be removed from the guide rail only by using a conventional screwdriver to lightly tap on a removal port. The screw is integrally connected to the housing by injection molding and thus there is no risk of the screw falling off, enabling higher reliability.
