Abstract: A subsea connector cable connection system has an interface and a retainer. One of the interface and the retainer has an external screw thread on a cylindrical section and the other has a corresponding internal screw thread on a cylindrical section. The interface further includes a conical body extending from the cylindrical section and the retainer further includes a corresponding conical internal surface extending from the cylindrical section and adapted to be spaced from the surface of the conical body when the interface and retainer are screwed together. Interaction of the conical body and conical internal surface produces a first end stop adapted to stop axial movement of the retainer. A second end stop remote from the first end stop is provided, adapted to stop axial movement of the cable. In one embodiment the connector may include a locking mechanism whereby undoing the joint requires more torque than doing up the joint.

Abstract: A system for joining a lug with a conductor includes a lug, compression nut, and conductor. The lug has material removed to allow for compression, an internal hole sized slightly larger than the conductor, and a tapered end. The compression nut has an internal thread and tapered end to match the lug. When assembled, the conductor is compressed against the lug creating a strong mechanical and electrical contact. The tighter the lug is screwed, the greater the compression between the lug and conductor.

Abstract: The subject invention pertains to a method and an electrical connector for coupling to a multi-stranded conductor. In a specific embodiment, the subject method and electrical connector can be used for coupling to an insulated multi-stranded conductor. In a specific embodiment, the subject connector can have: a housing having at least one bore for receiving an insulated multi-stranded electrical conductor; an electrically conductive prong located in the bore and electrically connected to the housing; and a securing means for insertion into the bore after insertion of the electrical conductor into the bore and onto the prong. Insertion of the securing means into the bore, after insertion of the electrical conductor into the bore and onto the prong, presses the strands of the electrical conductor against the conductive prong such that the connector makes electrical contact with the electrical conductor and acts to mechanically secure the electrical conductor to the connector.

The clamping tube is provided with a funnel-shaped connection opening and a connection chamber, into which the cable strands are insertable, wherein a clamping shoulder with a conical surface provided in the connection chamber adjoins the connection opening. The contact part, which can be screwed in the centre of the clamping tube and is thus displaceable axially, likewise has a conical surface, which penetrates the centre etween the bared strands on assembly and presses these against the conical surfaces and the clamping shoulder. The angles of the conical surfaces in the connection chamber and the contact part are executed differently in this case.

Abstract: A device for connecting wires. The device has two elements; an external element and an internal metal element. The external element is cylindrical and hollow. The external element has a central section with an outer surface that is hexagonal. The external element has an orifice at each end. Both orifices are sized into receive wires and have internal threads. The internal threads function to grip the insulation of the wires and draw the wires inside of the device to make contact with the internal metal element or contact. The internal metal element, or contact, is located inside the external element and is secured by an internal bearing surface. The internal element possesses sharp points for puncturing the insulation on filamentous wires that are inserted into the orifices of the device to complete electrical contact between the wires. Alternatively, the internal element has blunt ends for contacting solid wires.
