(54) SINGLE-POLE SEAL ELECTRIC CONNECTOR

one

The invention relates to devices for sealed interconnects made by cable-rope in underwater technology.

A single-pole sealed electrical connector is known, which contains two coupling halves, in telescopically coupled cylindrical cases of which insulators are installed, with elements and gaskets fixed in them, elastic bushing for sealing the cable and coupling nut connecting the coupling half l.

However, this connector is not sufficiently reliable, since when it is disconnected due to the resultant dilution, residues of water accumulated in structural cavities are sucked into the internal cavity and fall on contact elements. In addition, in this connector is difficult to connect the cable to the contact elements, which creates inconvenience in operation.

The purpose of the invention is to increase reliability by preventing moisture from contacting the connector when disconnecting the connector, as well as improving the convenience of operation. The goal is achieved by completing one of the coupling halves along the entire length of the coupling with the response coupling half, in at least , one is longitudinal notch, and through holes are made along the perimeter of the cap nut. At the same time, one of the contact elements has a tail in the form of a collet, crimped by an elastic sleeve, which makes it possible to attach the cable to the connector directly on the deck.

FIG. 1 depicts the proposed

5 is a connector, a longitudinal section in FIG. 2 is a section A-A in FIG. 1, in FIG. 3 is a section BB in FIG. 1, in FIG. 4 shows a section B-B in FIG. 1, in FIG. 5 - cable splitting - cable in front

0 connection.

A single-pole sealed electrical connector consists of two palu {luft 1 and 2, and the coupling half 2 can be made as a single unit with the body of the instrument unit. The coupling half 1 has a cylindrical housing 3, in which a housing 4 is formed, which forms a cavity 6 with the response cylindrical housing 5 of the coupling half 2. a recess 4 is made along the entire length

:;. it: neHHH packages. Sealed coupling half. The coupling is made with a n (.) M01tsyo sealing gasket 7 and a cap nut 8, screwed onto the housing of the coupling half 2. Inside the coupling halves 1 and 2 there is an electrical fixture that provides electrical connection and consisting of a socket 9, a shank which is made in the form of a cylindrical collet, which includes a wire 10 with the conductors 11 of the conductor core bent to the outer surface of the insulation.

Socket 9 is fixed in the half coupling

I through insulating sleeve 12

and nuts 13. The nut 13 has on the insulating sleeve 12, which, acting as an axle box, squeezes the rubber sleeve 14 through which it passes. wire 10 entering the collet of the socket 9 In this case, as a result of the elastic deformation of the rubber sleeve 14, the coupling half is sealed at the cable entry side and the collet of the shank of the socket 9 is simultaneously compressed, thereby making electrical contact of the socket with the wires

It is a conductive conductor.

The armature of the coupling half 2 contains a pin 15, which enters the socket 9, fixed in the insulating sleeve 16 by means of nuts 17 screwed onto the threaded shank, between which the tab 18 is clamped, which serves to make electrical contact with the elements inside the thermal instrument unit. The insulating sleeve 16 is retained in the housing with the help of 19. A bracket 20 is screwed onto the housing of the half coupling 1, to which the cover 22 is fastened with bolts 21. Power clamping of the cable armor 23 is carried out by means of a cable 20 and cover 22. the strap 20 and the cover 22 are provided with grooves provided with transverse projections made in the form of a thread. The slack of the wire required for the assembly of the electrical connector is placed in the form of a loop in the cavity between the bar 20 and the lid 22. To partially remove the water residues of the internal cavity

the union nut before disconnecting the connector serves as a drainage hole 24.

When loosening the union nut 8 and the mutual longitudinal displacement of the coupling halves at the initial moment of disconnection, the connection between the internal cavity of the connector and the atmosphere through the cavity b and the holes 24 of the union nut occurs. Thanks to such a compound, residue residue is eliminated.

0 non-removed water as a result of the interaction of the guides.

Cutting the cable as well as the design of the electrical connector allows you to quickly produce

5 termination of the cable and prevents soldering veins. The electrical contact between the conductive core and the collet of the socket is made simultaneously with the compression, the seal is looking for a sleeve.
