An electrical connection device including a support and an electrically conductive terminal lug, wherein the support includes a first face, with channels projecting from a second face opposite from the first face and defining between them a housing; the terminal lug includes a base for placing in the housing and a shank fastened coaxially to the base, the base including a first face from which the shank extends and a second face opposite from the first face for coming to bear against the second face of the support; the terminal lug including a locking ring having the shank passing through its center and movable in rotation relative to the shank, the ring including ramps extending from the outer periphery of the ring, the ramps co-operating with the channels.

An apparatus for locking welding leads together or for locking a welding lead connector to a welding machine terminal connector, and for protecting such welding leads. A method of locking welding leads together or locking a welding lead connector to a welding machine terminal connector.

A crimp connection system for electrical cables, including an electrical cable having a stripped cable end and a fastening sleeve. The stripped cable end is arranged at least partially within the fastening sleeve. The fastening sleeve has a number of fastening protrusions extending from the interior and/or outer surfaces of the fastening sleeve. The fastening protrusions are distributed over the interior and/or outer surfaces of the fastening sleeve. The crimp connection system also includes a contact terminal having a crimp portion. The fastening sleeve is arranged at least partially within the crimp portion.

A cable splice includes a casing having a central portion and a first end including a first aperture. The casing defines an interior cavity. A guide assembly extends through the first opening into the interior cavity. A first clamp member is positioned in the interior cavity and moveable between a loading position and a terminated position. A first biasing member biases the first clamp member toward the terminated position. A carrier is positioned in the interior cavity between the first biasing member and the central region. A second clamp member is positioned in the carrier and moveable with respect to the carrier.

A method of forming an electrode array includes the steps of positioning a workpiece on a mold part defining an opening and a channel and having undercuts, 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 covering processing tool performs a covering process of a cable connection portion and is provided with a first tubular unit extending in an axial direction, a second tubular unit disposed so as to surround the first tubular unit on an outer peripheral side, and a third tubular unit disposed so as to surround the first tubular unit on the outer peripheral side. The second tubular unit is installed on the first tubular unit so when extracting a first diameter expansion holding member of the first tubular unit, by supporting the second tubular unit from an outer peripheral side, relative movement in an axial direction and a circumferential direction of the first tubular unit relative to the second tubular unit is suppressed.

A single-core cable is protected over a long region by a pipe. A conductive path includes: a single-core cable in which end portions of a single-core wire are exposed; a first stranded cable in which an end portion of a first stranded wire that is exposed is coaxially fixed to the one end portion of the single-core wire; a second stranded cable in which an end portion of a second stranded wire that is exposed is coaxially fixed to the other end portion of the single-core wire; and a pipe that has an inner diameter dimension capable of surrounding the single-core cable and the first stranded cable, and is axially displaceable between a protective position at which only the single-core cable is surrounded, and an exposed position at which the one end portion of the single-core wire and the first stranded cable are surrounded, and the other end portion of the single-core wire is exposed.

The invention relates to an electric device, especially to a connecting rod, said connecting rod comprises a conductive first column portion that has an interference fit with a busbar, said first column portion axially arranges a conductive second column portion which has an interference fit with said first column portion, said second column portion is located inside of said first column portion, a thermal expansion coefficient of said second column portion is greater than that of said first column portion. Said transformer has such advantageous effects, 1. the same overlapping length increases more conductive surface for reducing a current density to achieve low temperature rising of connecting part; 2. amount of material is reduced and save the social source; 3. the electric clearance or safety distance is increased, an electric safety of device is also increased; 4. a width of a connecting part is reduced, an occupation space of transformer is also reduced.

A method of forming an end seal on a cable. The method includes placing a curable sealant in a cavity formed in a boot, inserting an end of the cable in to the cavity with the boot extending about the exterior of the cable, forcing the cable in to the curable sealant while inhibiting the egress of curable sealant from the boot to force the curable sealant along the interior of the cable, curing the curable sealant to provide a stable load supporting layer of sealant within the cable, and applying a crimping ring to the boot in the area of the load supporting layer to secure the boot to the cable.
