The invention relates to the field of electrical engineering, namely, devices multiphase high-voltage connectors.

Known single-phase high-voltage connectors, in which the insulator is made of elastic materials. The use of such connectors in a multi-phase connections are not reasonable because of the bulkiness and high cost of the resulting structures [1].

Closest to the proposed technical solution is the high-voltage device multiphase connector consisting of sockets and plugs with fasteners cable and solid bushing insulators, having insulating elements to ensure rapid bridging the gap in the connection, as well as contacts, mounted in insulators [2]. In the specified connector lock insulator entirely made of insulating material providing the necessary mechanical and dielectric strength of the insulator.

However, such design of the insulator has the disadvantage that it is fixed to the insulator conductor contacts do not have any possibility of relative movement, highly desirable to ensure proper entry of current-carrying contacts of the contact pairs when they join. The absence of such movement may cause damage or poor connection of connector contacts is A.

The aim of the present invention is the elimination of this drawback and improve the reliability of the connector.

This goal is achieved by the fact that in the high-voltage connector, multi-phase, consisting of two vzaimozachetnykh parts, plugs and sockets, comprising a housing, current-carrying contacts and bushings in each part of the connector is made in the form of a diaphragm having an insulating elements around each of the conductive contacts of the connector, the insulator of each part of the connector is made of an elastic polymeric insulating material, mainly of silicon rubber with inner reinforcement plate made of hard insulating material, mainly steklovidnogo sheet. Hole conductor contacts the reinforcing plate is made with a diameter equal to the outside diameter of the insulating elements.

Figure 1 shows a General view and coupled to the connector, and figure 2 shows two projections of the prison.

Plug 1, plug 2, the insulator 3 in the form of a diaphragm 4 having a site with 5 holes for mounting conductive contacts 6 and the insulating elements 7 around each of the holes for mounting conductive contacts 6 of the connector that provides the necessary dielectric strength insulation between electrical contacts 6 of the connector is made of an elastic polymeric insulation is an ionic material, mainly of silicon rubber with inner reinforcement plate 8 made of hard insulating material, mainly steklovidnogo sheet. When this hole in reinforcing plate under the current-carrying contacts 6 can be performed with a diameter equal to the outside diameter of the insulating element 7.

It is advisable that the outer diameter of insulating element 7 from one side of the diaphragm 4 was less than the internal diameter of the insulating elements 7 located at the other side of the diaphragm 4, so that it was possible to insert the insulating elements 7 one of the insulator 3 in the insulating elements 7 other insulator 3. In addition, the insulators 3 polurethane it is advisable to install so that the insulating elements 7 having a larger diameter in one polurethane housed in side abutting ends of the conductive contacts 6, and the second polyurethane - side attachable thereto cables, resulting in the coupling of paurashava insulating elements 5 into each other, and their geometrical dimensions provide a sealing connection of each contact pair 6 separately. This will allow to unify the insulators 3 and thereby reduce the cost of manufacture of the connectors.

When connecting two parts of the first connector includes at each other insulating elements 7, providing the op is realsie gap bridging ability, further connected between a contact pair 6. Elastic pad 5 provide relief of coincidence of the axes of the contact pairs, the reinforcing plate 8 provides the necessary rigidity and closing the ends of the insulating elements 7 and planes return insulators 3 provides sealing contact pairs 6. Thus, the elastic pad 5 allow the contacts 6 to be displaced relative to each other, thereby facilitating Assembly of the connector and at the same time provide a reliable electrical insulation, eliminating the possibility of surface breakdown on the reinforcing plate 8.
