A dry mate cable connection includes a data cable. The data cable includes a plurality of electrical conductors and at least one electrically insulating outer layer surrounding each data conductor, whereby the data conductors are electrically insulated from one another. The cable includes a termination end. The outer layer of each conductor is physically in contact with an outer layer of an adjacent conductor, except at the termination end. The plurality of electrical conductors at the termination end are physically separated from one another by a single electrically insulating overmoulded cable termination housing. The housing is in contact with at least part of the electrically insulating layers of each of the electrical conductors.

Cable connection

An ROV, diver, or stab, wet mateable connector plug front end housing includes a housing front section; a locator mount section; and a seal section axially in series with one another. The housing front section includes a plug coarse alignment feature on an outer surface of the housing front section, adjacent to a front surface of the housing front section and radially outward of a central axis of the housing. There is a circumferential groove on the outer surface of the housing front section, axially displaced from and rearward of the coarse alignment feature, the groove being adapted to receive a latch of a wet-mateable connector receptacle front end housing. The plug coarse alignment feature includes a bullnose feature. A plug fine alignment feature is formed in the outer surface of the housing front section, aligned with and located radially outward of the central axis of the housing.

An electrical connector having a first connector part and a second connector part, the first connector part with at least one electrically conductive pin and the second connector part with at least one shuttle pin, the conductive pin having two or more electrically conductive cores, each conductive core being provided with an external electrical contact and an insulating material forming a watertight seal with the conductive core and the electrical contact. The conductive cores include two or more cores spaced from one another to form the conductive pin. Facing surfaces of the two or more cores are spaced by an air gap with insulating material in the air gap and overmoulded insulating material is in contact with other surfaces of the conductive cores.

Connector and method of manufacture

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.

Cable connection and method
