(54) KNOT OF CONNECTING CABLE WITH ELECTRIC CONNECTOR

t

The invention relates to electrical engineering, in particular, to a cable connection unit with a marine electrical connector, designed for operation under conditions of increased hydrostatic pressure, and can be used when connecting cables to submersible electric motors.

A cable connection unit with an electrical connector is known, comprising a block with the contact details of the connector, cable cores connected thereto, enclosed in a hermetically sealed housing, which consists of several parts 11.

In the known connector, the cable is brought to the side surface and access to the soldering points of the cable wires to the contact parts is possible only from above. This necessitates the presence of the lateral part of the body of tubular contact parts, at one end of which the cores are strapped and the other part includes the contact part; mounted in another part of the case. Intermediate uono.iFmTe.nbHbix of intermediate tubular contact parts leads to a decrease in operational reliability ™ and an increase in the electrical resistance of the joint assembly.

The known joint assembly also does not provide the possibility of fastening without squeezing the cables differing in outer diameter.

A connection node is also known, in which the indicated disadvantages are eliminated (2).

This assembly contains a metal cup and a sleeve, hermetically mounted on the cable sheath, the cut-off conductors of which are connected to the contacts of the connector, are placed in a glass that is detachably connected to the sleeve and the connector body. At the same time, the joints are sealed with vulcanized rubber.

However, the known device provides the connection of only one cable supplied along the axis of the connector.

The purpose of the invention. is an extension of functionality.

Claims (2)

This goal is achieved by the fact that in a well-known cable connection unit with an electrical connector with sealing joints with rubber containing a metal cup and a sleeve sealed on the cable sheath, the sheathed wires of which are connected to the connector contacts are connected to the sleeve. and a connector housing, the sleeve is made with a flange at an angle of 30-90 to the axis of the sleeve, the cup is made of a composite, at least two parts with a longitudinal line of the connector, with this sleeve flange and installed at the end of the glass, and the internal volume of the latter is filled with electrical insulating components. The essence of the proposal is illustrated in the drawing where it is shown in FIG. i - general view of the node; in fig. 2 - ceiKHiie A-A of FIG. 1. The joint assembly comprises a housing I in which contacts 2 are mounted, a cup consisting of several parts with a longitudinal pin connector, for example two, 3 and 4, a sleeve 5 with a flange 6. located at an angle of 30-90 °. Sleeve 5 is vulcanized with rubber 7 to the sheath of cable 8, conductors 9 of which are fed to contacts 2. The glass is connected with screws 10 to housing 1, and screws And to flange 6 of the sleeve. The inner volume of the cup is filled with the electron insulating compound 12, and the outer surface of the assembly is rubberized. The assembly of the assembly is carried out as follows. On the sheath of cable 8, rubber 7 is vulcanised by sleeve 5 with flange 6 attached, the core 9 of cable 8 is cut and soldered to contacts 2, after which parts 3 and 4 of the cup are fixed to housing 1 with screws 10 and flange 6 is fixed to parts 3 and 4, and then filling the internal volume of the joint with the electrically insulating composition 12 through one of the holes sealed by the screw 11, and the outer surface of the joint of the joint is rubberized. Such an implementation provides the ability to connect cables at an angle to the connector, as defined by the tilt of the flange, reliability and ease of installation. Claims The cable connection unit with an electrical connector with rubber sealing joints, containing a metal cup and a sleeve, is fixed to the cable sheath, the divided wires of which are connected to the connector pins, are placed in a glass plug connected to the sleeve and the connector body, characterized by that, in order to improve the functionality, the sleeve is made with a flange disposed at an angle of 3 ° C-90 ° to the axis of the sleeve, the glass is made of at least two parts, with extension hydrochloric parting line at ztom fshshets sleeve mounted on spergula stakasch and vnugr greatest volume of the latter is filled ektroizol tsiogashm composition.
