A device includes a body portion and a moveable fastener extension coupled to the body portion. The moveable fastener extension is configured to be inserted in an opening of an electrical ground lug and an opening of an object to be grounded. The device further includes a handle coupled to the moveable fastener extension and configured to be operated by hand to manipulate the moveable fastener extension to secure the electrical ground lug to the object via the device.

A female welding lead connector including a safety cover hingedly connected to a main body of the female welding lead connector. The safety cover preferably includes a fastener for fastening the cover to a closed position, shielding a female welding lead receptacle inside the main body of the female welding lead connector.

A method of forming an electrode array includes the steps of positioning a workpiece on a mold part, compressing the workpiece into the mold part to form a contact, and introducing resilient material into the mold part to form a flexible body.

A method for manufacturing a power distribution member includes preparing a solid wire with a circular cross-sectional shape, pressing to a portion of the solid wire in a pressing direction orthogonal to the solid wire to cause plastic deformation, thereby forming a pair of small curvature surfaces on an outer circumference of the solid wire on both sides in the pressing direction, the small curvature surfaces having a smaller curvature than an outer circumferential surface of the solid wire before the pressing and facing the pressing direction, preparing a terminal metal piece including a pair of facing walls facing each other and a coupling wall coupling between ends of the pair of facing walls, inserting the solid wire after the pressing between the pair of facing walls of the terminal metal piece in such a manner that one of the pair of small curvature surfaces faces one of the pair of facing walls and the other of the pair of small curvature surfaces faces the other of the pair of facing walls, and, after the inserting, crimping the pair of facing walls onto the solid wire.

Method of manufacturing a ground apparatus and ground apparatus comprising an aluminum nut (16) having an internal thread and adapted to clamp an eyelet (28) of an electrical conductor on a corresponding contact area of the stud (12), wherein the nut (16) has at least one coating (30) which contains at least zinc, characterized in that the coating further comprises tin, in that the coating consists of an acid tin-zinc electroplating on the aluminum nut (16) and is such that the tin is between 60 and 80% by weight of the coating and the tin-zinc coating forms a layer with an average thickness of from about 5 to 16 microns.

The present disclosure relates to a magnetic assembly structure which utilizes a magnetic attraction or repulsion effect generated by two magnetic components to make two buckle structures automatically engaged to each other. The magnetic assembly structure of the present disclosure has a first main body and a second main body, and via the hardware design of disposing magnetic components and buckle structures respectively on the first main body and the second main body, the first and second main bodies rotate in respect to each other due to the magnetic attraction or repulsion effect, so as to efficiently engage the two buckle structures each other. Thus, it actually eases the installation and uninstallation of the appliance to which the magnetic assembly structure is applied, and the costs of installation and consuming time are reduced.

A harness is provided with one or more first wires each including a first core exposed portion, one or more second wires each including a second core exposed portion, and a bonded portion formed by welding the first and second core exposed portion(s). A total cross-sectional area of the second core(s) is equal to or less than ⅓ of the sum of total cross-sectional areas of the first and second core(s). The bonded portion has two pairs of outer surfaces extending along an extending direction of the first and second wires and facing each other and a distance H between one pair of the outer surfaces (upper/lower surfaces), out of the two pairs of outer surfaces, is longer than a distance W between another pair of the outer surfaces (right/left side surfaces). The second core exposed portion(s) is/are arranged adjacent to the upper surface Up in the bonded portion.

The present disclosure relates to an electric wire connection structure including one or more copper-based conductor covered electric wires having a copper-based conductor covered part and exposed part; and one or more aluminum-based conductor covered electric wires having an aluminum-based conductor covered part and exposed part. An ultrasonic joint part is provided at a conductor stacked part in which the copper-based conductor exposed part and the aluminum-based conductor exposed part are superposed. A total contacting length L which is a summed length of a part at which the copper-based conductor exposed part and the aluminum-based conductor exposed part contact and a summed length x of a contour line of a space S formed at a part at which the copper-based conductor exposed part and the aluminum-based conductor exposed part are separate in a joint interface of the ultrasonic joint part satisfy a relational expression of (x/L)×100≤10% based on cross-section observation.

The invention relates to a method of connecting electrical wires, conductors, or connections together by rotating the connector ends in an enclosure to tightly twist the wire ends together and also includes a clamping mechanism to prevent the wires from untwisting, becoming loose, or falling out of the enclosure. The present invention increases the holding ability of current rotating tools for electrical wires and connections.
