Abstract

The invention relates to electrical engineering. The aim of the invention is to improve the reliability of the connector. When the two parts of the connector junction, they first touch the surface of the two parts of the insulation located near the contact elements, then when the cap nut 21 is tightened, the spring 22 is compressed and the elastic insulation of one part is pressed to the other. As a result of the presence of an increasing gap between the two parts of the insulation in the initial position, in the butted position, the maximum seal of the insulation is obtained near the contact elements 7 and 8 and decreases with increasing the radius of the body of rotation, which eliminates the leading bubbles at the junction. In the butted position, the annular protrusion 20 fits into the annular groove 19, which eliminates the torsion of the elastic insulation of one part relative to the other, as a result, the reliability is significantly increased. To ensure reliable fixation of the contact elements 7 and (L T o 00 OS

This invention relates to electrical engineering, in particular to hermetic electrical connectors.

The object of the invention is to increase the reliability of operation.

FIG. 1 shows a deep-water high-voltage electrical connector in the articulated position; FIG. 2 is a section A-A in FIG. 1, FIG. 3 is a schematic arrangement of the abutting surfaces of elastic insulation, in FIG. 4 is a section BB in FIG. 1.

The deep-water high-voltage electrical connector (FIGS. 1 and 2) consists of two parts - sockets 1 and plug 2, mounted in detachable housing 3 and 4, each of which contains cable fasteners 5 and 6, contact elements 7 and 8, covered by elastic insulation 9. The forming interface of the insulation between two parts 10 and 11 (Fig. 3) has the shape of a body of rotation and is implemented as a cosine curve satisfying the equation

where d is the maximum gap between the generatrix of the junction of the elastic insulation of the socket and the plug at the point.

Proceeding from this equation, the surface of the isolation of one part with respect to the other in the initial position is made with an increasing gap (Fig. 3). So, for example, given by the value of X, which determines the increase in the radius of the body of rotation, according to the equation, obtaining the gap A

Thus, due to the presence of an increasing gap between the two parts, with the initial position in the coupled position, the maximum seal of the insulation is obtained near the contact elements 7 and 8 and decreases as the radius of the body of rotation increases. -Each contact element 7 and 8 sleep bzhen spherical washer 12 (Fig.1 and 2) with a central hole 13 in the form of a cone with two diametrically spaced grooves 14 (Fig.2). The base of the cone 13 is directed towards the side of the corresponding cable 15 and 16. On the outer side of the elastic insulation, both parts are detachable

the cases 3. and 4 are reinforced with rings 17 and 18, each of which fixes a corresponding part of the split housing 3 and 4. One part of the split housing, for example 3, is provided with an annular groove 19 on the inner side of the joint, and the other 4 with an annular protrusion 20, Fixing the corresponding housing 3 and 4 to the rings 17 and 18 (figure 4) is made by the protrusion 20, and the compression of the two parts of the connector between them is provided with a plug 2t and a spring 22 (figure 1). The cables 15 and 16 are mounted in the corresponding sleeves 23, on which diametrically located protrusions 24 are included, which are included in the grooves 14,

vibration and shock loads allow deep-sea high-voltage elec-j5 to increase reliability and durability

services 1.5-1.7 times due to the fact that each part of the connector of elastic insulation is made in the form of a socket and plug, the interface of which in cross section is made in the form of a cosine, and also the isastric connector works as follows.

When articulating the two parts of the connector, the surfaces of the two parts of the insulation located near the contact elements first touch, then when the cap nut 21 is tightened, the springs 22 are compressed and the elastic insulation of one part presses against the other, resulting in an increasing gap between two parts insulation at the initial position in the open position, the maximum seal of the insulation is obtained near the contact elements 7 and 8 and decreases with increasing radius of the body of rotation, which eliminates air nye bubbles at the joint when interfacing. The seal is reduced, but its size should be sufficient to eliminate the appearance of: a gap between the joining parts of the insulation when exposed to elevated environmental pressure and vibration or shock loads. As a result, the electrical strength of the overlap along the interface increases sharply. In addition, in the docked position of the col-. The ninth protrusion 20 enters the annular groove 19, which eliminates the skewing of the elastic insulation of one part relative to the other, as a result of being. Reliably increases to ensure that the contact elements 7 and 8 are securely fixed in elastic insulation, spherical washers 12 are installed in it, in each of which through a sleeve 23 on one side there are rigidly
