A cable joint includes a cable joint body, a conductive connector disposed within the cable joint body and electrically connecting a first cable to a second cable, and a first conductive element electrically connecting a first shielding layer of the first cable to a second shielding layer of the second cable. The cable joint body includes a first insulating sleeve and a re-jacketing sleeve at least partly encompassing the first insulating sleeve. The re-jacketing sleeve forms a channel along a longitudinal axis of the first insulating sleeve. The first conductive element is disposed within the channel. The channel is collapsed after heat shrinking the first insulating sleeve and the re-jacketing sleeve.

A device for electrically connecting a cable metallic shield to another electrical element includes a neutral connection portion and an extended connecting member. The neutral connection portion is a flexible contact strip for electrically connecting to the metallic shield of the cable. The extended connecting member connects to the neutral connection portion and is used to electrically connect to another electrical element. The extended connecting member has a plurality of electrical members disposed over the contact strip. A clamping device biases the contact strip against the metallic shield of the cable. In use, an environmental jacket from the electrical cable is removed to expose the metallic shield of the cable. The contact strip is wrapped around the exposed metallic shield, and the clamping device is then connected to the contact strip. Another end of the extended connecting member is then used to connect to the other electrical element.

A high-voltage cable set, in particular for a vehicle electrical system, contains a plurality of cables, which are surrounded by a common shield, and a connector, which consists of a conducting material and is electrically connected to the shield. For this purpose, a contact sleeve is integrated into the connector, the shield being fastened to the contact sleeve. The risk of contact corrosion is thereby significantly reduced.

A two-way crimpless butt connector is provided. The butt connector includes a cylindrical housing including a pair of open ends providing two-way entry into the housing, a cylindrical conduit including a pair of open ends each configured to receive an end of a wire therein, and a fastener configured to secure and adjoin the pair of wire ends in the conduit. The fastener includes bendable teeth disposed on the open ends of the conduit. The teeth protrude radially inwardly and form an opening including a diameter smaller than a diameter of the wire ends. When a wire end is inserted into the conduit, the teeth bend with the wire end, thereby engaging the wire end and securing it within the conduit. In this way, the wire ends may be inserted into the housing, adjoined, and locked in the conduit without the use of a crimper, thereby establishing an electrical connection therebetween.

A method for contacting a wire (1), in particular an aluminum wire, with a connecting body (4), in particular with a plug of a coil body (5), comprising the following steps: connecting the wire (1) materially to the connecting body (4) at at least one point (2, 3); after connecting, enclosing a connecting region including the at least at one point (2, 3) is by a shrink tube (6) with an inner glue (7), the shrink tube (6) encompassing the connecting body (4).

An electrical cable is provided with a rounded insulated electrical conductor that transitions to a flattened section to fit into areas where the rounded portion does not fit. A round electrical conductor transitions to a flattened section for electrical conduction routing via the undercarriage of a vehicle, for routing under the carpeting of the passenger compartment, or other confined spaces. The electrical cable may illustratively be used in an electric car application where distribution of electrical current from the battery compartment to the motor requires additional wiring in the vehicle not found in combustion based engines. The reduced vertical profile of the flattened section provides for additional clearance between the vehicle undercarriage and the road, or between the undercarriage frame and the interior passenger compartment carpet.
