A conductive member of the present invention includes: a metallic conductive base material including a joining region to be joined to another conductive member when the conductive member is used; and a conductive-auxiliary-coating-agent layer for imparting conductivity and an oxidation preventing property to a joining section between the joining region and another conductive member when the conductive member is used, the conductive-auxiliary-coating-agent layer being formed by applying a conductive auxiliary coating agent to the joining region of the conductive base material, in which the joining region of the conductive base material has a surface roughness of 0.6 μm or less in terms of an arithmetic mean roughness Ra specified in JISB0601 (1994).

The invention relates to a direct burial ground lug. The lug is preferably constructed of a phosphor bronze material. The block may have two through holes to install two conductors, rods, cables, and the like. Stainless steel threaded screws are used to hold the rod and ground conductor in a stable condition. The threaded screws insert into threaded holes positioned perpendicular to the through holes. The direct burial ground lug allows the ground rod and ground conductor to be connected for a continuous grounding system.

A connection structure, of a short bar forming a conductive path and a land on a printed circuit board, in which the short bar includes a plate portion having a flat plate shape and a protrusion protruding in a stepped shape from a surface of the plate portion, the protrusion is threadably fastened to the printed circuit board by a screw inserted into a land-side through hole formed through the land, from an opposite side of the printed circuit board with respect to the protrusion, in a state where a flat surface portion formed, at a position spaced apart from the surface of the plate portion, on an outer surface of the protrusion is in close contact with the land.

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.

An electrical terminal, a corresponding electrical assembly, and a related installation method are disclosed herein. An exemplary embodiment of the electrical assembly includes an electrically conductive threaded mounting post, a threaded fastener that mates with the mounting post, and a terminal for an electrical conductor. The terminal has a deformable feature that compresses when the fastener is installed to clamp the terminal between a contact surface of the mounting post and the fastener. The deformable feature has mechanical properties and characteristics such that torque required to compress the deformable feature increases during installation of the fastener.

Systems and methods for providing screw bosses on a substrate. The substrate can be dimpled. The dimples can then be threaded to accept screw bosses. The dimples can be threaded using a threading die or can have threads cut by self-tapping screw bosses. An adhesive can be applied to the substrate, the bottom of the screw boss, or both. The screw bosses can include standoffs to determine the distance between the bottom of the screw boss and the substrate. The screw bosses can be threaded onto the dimples and can provide threads for attaching items to the substrate. A filler material can be applied to the reverse side of the substrate to fill-in the dimples and present a smooth surface. A decorative or protective layer can be applied over the filler material.

Solar panel grounding lug assemblies and systems are disclosed. The grounding lugs may include a top member having a grounding wire channel and an aperture, a bottom member having an aperture, and a fastener inserted through the apertures. The fastener may couple the top member to the bottom member and secure a grounding wire within the grounding wire channel.

A cable lug or functional part in combination with a nut is provided. The cable lug or functional part has a tubular receiving portion for a cable, an integrally formed flat part connecting portion connected to the tubular receiving portion, the flat part connecting portion having a hole therethrough defined by a wall said hole having a central axis. The nut includes a body having an undercut. The nut is held captively and rotatably on the flat part connecting portion. The nut does not pass through the flat part connecting portion is held by a reshaped holding material portion of the flat part connecting portion which projects into the undercut. The reshaped holding material portion is accommodated in the undercut, and an axial clearance is provided between the reshaped holding material and the wall which defines the hole.

A connecting arrangement for a three-level converter arrangement includes a first to third connection rail which are each in the form of a shaped metal body. The respective connection rail has a line section and a connection section which has a connection means. The respective connecting rail has a line section and a connecting section which, for its part, has an associated respective connecting means. The respective connection means forms, with the connecting means, a force-fitting, electrically conductive connection. The connection rails are connected to the connecting rails with the correct polarity. The respective line sections of the connection rails and the connecting rails are situated one above the other in a stack, wherein the first connecting section, in projection in the normal direction of the first connection section, covers the first connection section; wherein the second connecting section, in projection in the normal direction of the second connection section, covers the first connection section and the second connection section, and wherein the third connecting section, in projection in the normal direction of the third connection section, covers the second connection section and the third connection section.
