A resilient grounding clip including: a head having an aperture disposed in the head; a first leg having a proximate end connected to a first edge of the head, where the first leg is disposed at an obtuse angle relative to a first surface of the head; a second leg having a proximate end connected to a second edge of the head, where the second leg is disposed at an obtuse angle relative to the first surface of the head, and where the first edge is opposite the second edge; a first tab connected to the first leg at an end distal from the end connected to the head; and a second tab connected to the second leg at an end distal from the end connected to the head.

A miniaturized metal joint body and an apparatus for manufacturing the metal joint body to be improved about strength are provided. By cutting three overlapped metal sheets along a first cutting line and a pair of second cutting lines extending so as to intersect the first cutting line at each end of the first cutting line and pressing areas surrounded with the first cutting line and the pair of second cutting lines and each of a pair of bending lines connecting both ends of the pair of second cutting lines, each of the pairs of projecting members is formed so as to project in a pressing direction of arrow z.

A washer includes a conductive main body, a first seal portion, and a second seal portion. The main body includes an annular plate-shaped body and a protruding portion. The protruding portion protrudes in the thickness direction from the outer peripheral portion of the plate-shaped body. The first seal portion covers the inner peripheral surface at the inner peripheral portion and both surfaces in the thickness direction of the plate-shaped body. The second seal portion covers at least the distal end portion of the protruding portion.

A working machine includes an electrical component, at least two structural bodies each having electrical conductivity, and a conductive screw to conductively connect the at least two structural bodies to each other.

A torque-limiting nut for a break-off bolt includes a thread section having an internal thread, a head section having an abutment shoulder extending further toward a radial inward direction than the internal thread, and a predetermined breaking area separating the thread section and the head section. The abutment shoulder is arranged adjoining to the predetermined breaking area.

The present technology relates to novel conductive polymer rivets designed to allow a user to ground a shoe, including a sandal. They allow for easy installation into various types of shoes resulting in a comfortable, aesthetic and grounded shoe. The present technology also relates to kits incorporating such conductive polymer rivets with instructions for inserting such rivets into a shoe. The present technology further relates to methods of inserting such conductive polymer rivets into shoes. The present technology also relates to shoes with the present conductive polymer rivets inserted therein.

Aspects of the present disclosure relate to a self-mating fastener that includes a backing having a first side, and a rail element protruding perpendicularly from the first side of the backing. The rail element extends in a longitudinal direction along the backing. The rail element has a base portion attached to the first side of the backing and a cap portion distal from the backing. The cap portion has a cap width that is greater than a width of the base portion and the cap portion overhangs the base portion on opposing sides. The self-mating fastener includes an electrically conductive contact element proximate to the rail element.

An anchor for components of a lightning protection system may rely on a bonding agent, such as an adhesive, needing time for curing, drying, or otherwise setting (increasing in adhesion, strength, mechanical stability, or any combination thereof) by remaining in place while setting. The anchor may be suspended by a lip extending horizontally past an edge (plane of intersection of two planar surfaces) where a base plate is adhered to a vertical surface and the lip rests, registers in translation, and squares in rotation against a horizontal surface sharing an edge or fold (corner, bend) with the vertical surface. Once set sufficiently, the adhesive supports loads in shear (along plane of adhesion) and tension (perpendicular to plane of adhesion) imposed by brackets holding a cable, point, or both at each base plate.

A PV module alignment or attachment system and method that contains multi-connectors that interact with the modules along rows or columns of an array of the modules. In some versions, the multi-connectors connect to frames of the modules in a row or column and maintain the module-to-module height between modules. The multi-connectors connect to flanges on the frames, which flanges are molded into the frames or bolted to the frames.

A fastening arrangement comprises a first component that is repeatably releasably fastenable to a second component, and an additional part. The additional part is pivotable about a pivot joint between an open functional position, in which a joining portion of the first component is joinable to a receiving portion of the second component, and a closed functional position, in which the joining portion of the first component is received in the receiving portion of the second component. During a transition between the functional positions, the additional part passes through an unstable dead-center position.
