Abstract

The invention relates to electrical engineering. The aim of the invention is to increase reliability. The connector includes a cylindrical body 1, in the cavity of which the sleeves 2 are located with cables fixed in them. Between the sleeves 2 are the connecting elements for the cable cores. The sleeves 2 are installed with the possibility of reciprocating motion and are sealed on the output side with an epoxy compound 7. The cavity 11 in the middle part of the housing 1 is filled with an electrically insulating liquid. The implementation of a piston-type sealed sleeve provides the back pressure when the connector is immersed, increasing with increasing depth of the connector, which ensures the reliability of the connector. 1 hp ff, 1 ill.

The invention relates to electrical engineering,

The purpose of the invention is to increase reliability, g

The drawing shows a cable connector, a longitudinal section.

The cable connector consists of a cylindrical body 1, the ends of which on the outer side have a thread, sleeves 2 placed inside the polished cylindrical surface of the body 1 and having grooves for additional sealing elements 3, end sealing elements 4, pressure metal nuts 5 and pressure metal washers 6. Sealing elements can be made, for example, of rubber.20

The sleeve cavity on the cable outlet side is sealed with a layer of epoxy compound 7, and separated cable cores pass through the perforated disk 8. The insulating sleeve 9 prevents the cores from touching the housing in case of insulation damage. The connecting elements 10, which are insulated with vinyl chloride, are soldered to the ends of the cable cores. In the middle 30 of the housing there is a cavity (between the sleeves) 11 filled with a polyethylsiloxane fluid having electrical insulating properties .35

The minimum diameter of the cable 12 to be sealed must correspond to the diameter of the cylindrical bore of the sleeve 2. The hole has a threaded notch that bakes the adhesion of the cable surface to the internal surface of the sleeve when using an adhesive composition, such as epoxy compound K-115.

The cable connector is assembled in the following sequence. First, parts 1, 4, 5, and 6 are installed on the cable, then the cable is cut and cables are installed into bushings and the cables are spliced. Then, the sleeves with cables are inserted into the housing and the cavity between the sleeves is filled with electrical insulating liquid.

The connector is provided with a sealed piston-type sleeve with sealing elements, and the cavity between the sleeves for accommodating the connected cable cores is filled with an electrically insulating liquid, which is in preloading, which is carried out with the help of pressure nuts. At the same time, with an increase in the immersion depth, a further increase in the back pressure in the fluid chamber occurs, ensuring the tightness of the junction.
