A cable termination apparatus for an underwater cable with a conductive core, an axially extending annular insulation portion radially outwardly of the core and an axially extending annular conductive screen layer radially outwardly of the insulation portion. The apparatus having a stress control sleeve, located radially outwardly of the insulation portion and extending partially over the annular conductive screen layer. The stress control sleeve includes an insulating portion and a conductive portion. When the cable termination apparatus is assembled the conductive portion of the stress control sleeve is in contact with an end portion of the screen layer.

A technique facilitates mechanical and electrical connection between components. The components may be coupled mechanically by a threaded engagement and electrically by first and second electrical couplers. The first and second electrical couplers may each have a plurality of electrical contacts oriented for linear engagement. The electrical contacts of the second electrical coupler are mounted on a first portion of the second electrical coupler which is rotatably received by a second portion to enable linear engagement of the electrical contacts while rotating the components relative to each other to form the mechanical connection.

Electrically insulated connector bands for Downhole Electrical Disconnect Tools provide power and/or data communication downhole are made from metal having sufficient strength and corrosion resistance to eliminate the need of any vacuum and sealed pressure compensation assembly while being exposed to wellbore fluids. The electrical insulation is achieved by having portions of the connector bands coated with electrically insulating material. An uncoated section of each connector band will provide the electrical path between the male and female mandrels.

The invention relates to a device for guiding a cable for linking a submerged robot, in particular a robot for cleaning swimming pools, to the device for controlling and powering same, said guiding device comprising: a. a coupling including a rotary connector, connected by one side to a first floating portion of the linking cable extending from the control and power device to said coupling and, by the other side, to a second portion of the linking cable extending from said coupling to the submerged robot; b. a floating mounting including: bi. a float; bii. an interface for mechanically linking the rotary connector to said float; and biii. a hood extending above the surface when the floating mounting is submerged in a liquid and removably connected to the float; c. in which the mechanical link between the float and the rotary coupling is a ball-and-socket link.

A method of dry-mating a first connector part and a second connector part wherein the first and second connector parts are brought into a first mated state, wherein a seal is engaged between the first and second connector parts. A sealed inner space is formed between the first and second connector parts. The sealed inner space is evacuated through an evacuating port. The evacuation port is arranged such that it is located on an inner sealed side of the engaged seal in the first mated state. Further, the first connector part and the second connector part are brought into a second mated state, wherein a seal is engaged between the first connector part and the second connector part such that the evacuation port is located on an outer side of the engaged seal so that it is no longer in flow communication with the sealed inner space.

A terminal block for transitioning electrical connections between two adjacent areas comprises at least one hole for receiving a stud. Each hole comprises a through hole and a sealing chamber surrounding the through hole. A stud is used for each hole. Each stud comprises a seal support flange and a sealing device. Each side of the seal support flange comprises a system for making an electrical connection. The seal support flange is sized to fit within the sealing chamber. The sealing device is located between the support flange and the sealing chamber. The stud is secured to the hole on the opposite side of the dielectric insert from the support flange and the sealing chamber to compress the sealing device between the support flange and the sealing chamber and cause the sealing device to fill the space of the sealing chamber and form a seal between the stud and the sealing chamber.
