Description

 I

j The invention relates to electrical engineering and may find application in areas of underwater technology where multiple switching of electrical circuits is required.

Known electrical connector containing two mating parts, in the case of one mating part is a contact, made in the form of a rod, and the body of the other mating part is made in the form of a glass, in the cavity filled with liquid, the contact Cl is installed.

The disadvantage of this connector is the inability to dock and disconnect in water under stress.

The purpose of the invention is to improve the reliability of the connector in operation.

To achieve this goal, the electrical connector is provided with a casing made in the form of a cup of resilient electrically insulating material, the bottom of which faces towards the sub-connection, spring-loaded non-return valve, mounted for movement, a bellows with a bottom made of resilient electrically insulating material, bellows covers the rod, forming a sealed cavity, the sharp end of the rod is directed towards its bottom, the casing covers the glass of the other counterpart, forming a sealed cavity, on the inside th surface of the casing, by connecting mating part is mounted obratnv valve and said electrically insulating fluid is selected.

In addition, the spring-loaded non-return valve is made in the form of a disk made of electrically insulating material with a metal cone on its surface.

Figure 1 shows the plug; in Fig. 2, a socket} in Fig. 3 shows a conductive contact; figure 4 - check valve; figure 5 - electrical connector general view. The plug is a pin 1 made in the form of a rod, which is located in the bellows 2, made of an elastic electrically insulating material. The plug is mounted on the housing 3 of the removable part 4 of the submersible header connector. The socket is made in the form of a cup 5, hermetically sealed with the casing-6, made of an elastic insulating material filled with electrically insulating liquid 7 and containing current leads pin 8, which is spring-loaded spring 9 and has freedom of movement — in a direction perpendicular to contact axis 1. Contact 8 is located in the electrically insulating liquid 7, which provides spark extinguishing at the time of the electrical connection, and is fixed on the insulating gasket 0. Contact 8 has the shape of a cut lindric sleeve, the end of which is flared. The entrance to the receptacle cup 5 is closed by a check valve 11, which is made in the form of a disc made of electrically insulating material with a metal nozzle in the form of a cone. The pressure drop is compensated by the membrane 2 installed in the cap 13. Outside, the cable outlet 14 is connected to the socket. The socket outlet is mounted on the housing 15 of the stationary part 16 of the subsea connector connector. The use of guide protrusion 17 and corresponding socket 18, as well as guide ropes 19, pins 20 and corrective sleeves 21 in the collector-connector allows for precise docking under water without the diver's participation. The subsea collector-connector is connected to a surface source of electrical power through a reinforced submarine cable 22. The electrical connector operates as follows. The detachable part 4 of the underwater collector-connector along the guide ropes 19 is lowered and docked with the stationary part 16. 84 Contact 1 punctures the protective bellows 2, as well as the casing 6 sockets and, bending the check valve 11, comes in contact 8, ensuring a reliable connection due to springs 9. Tightly joined bellows 2 and -casing 6 provide reliable insulation and sealing. The bellows 2 can be replaced as far as triggered. The use of an electrical connector allows docking and disconnection under water without the participation of a diver, improves the performance of the connector and extends its service life. Claim 1. An electrical connector comprising two mating parts, in the case of one mating part there is a contact made in the form of a rod, and the case of the other mating part is made in the form of a glass, in its cavity filled with liquid, a contact is made, characterized in that in order to increase reliability in operation, it is provided with a casing, made in the form of a cup from an elastic electrically insulating material, the bottom of which is turned towards the connection, spring-loaded with a check valve installed with bellows with a bottom made of elastic electrically insulating material, the bellows encloses the rod, forming a sealed cavity, the end of the rod is directed towards its bottom, the casing covers the glass of the other counterpart, forming an airtight cavity on the inner side of the casing , a check valve is installed, and the specified fluid is electrically insulated. 2. A connector according to claim 1, characterized in that the spring-loaded non-return valve is made in the form of a strip of electrically insulating material with a metal cone on its surface.
