Abstract

The invention relates to electrical engineering. The aim of the invention is to increase the reliability of fixing the contacts. To prevent the contacts from moving in the longitudinal and transverse directions, the element for fastening the contacts in the insulator is made in the form of a transverse groove 21 located in the middle part of the contacts. The contacts are installed in the shaped holes of the main insulator so that their transverse grooves 21 cover the specified isotope in the area of the longitudinal grooves. A protrusion 25 located in the cylindrical part of the shaped hole is made in the additional insulator. 9 il. And-a with (L with oo; o with Figure 2

Description

The invention relates to electrical engineering, in particular to detachable connecting devices used for switching electrical circuits.

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

FIG. 1 shows the socket of the connecting device; in fig. 2 shows section A-A in FIG. one; in fig. 3 - plug coupling device; in fig. 4 shows a section in FIG. 3; in fig. 5 - sleeve; in fig. 6 - pin connecting device; in fig. 7 is a figured window in an insulating plate of the socket; in fig. 8 the same, in the insulation plate of the plug; in fig. 9 - location of the projections in the isolator of the socket.

The socket (Fig. 1 and 2) includes a housing 1, along the axis of which 2 KpbinjKa 3 is fixed, spring-loaded with a spring 4, fixed ii; i; ; o) 1 with the help of rivets 5. On KOfiruse 1, two insulators of cyopic elements are fixed by expanding the projections 6 - the main insulator is the main one) ISOLATION 11., 1 7 and additional in the form of an insulator 8 with assembled gi .chz-9 and pins 10.

Thus, in this plane, the section of the sleeve 9 or the pin 10 is a segment. The height of the groove corresponds to the thickness of the insulation plate 7 or 14.

In the insulating plate 7 sockets, figured holes are made according to the number of clocks. Each figured hole consists of a cylindrical part 22, which transforms into a longitudinal groove 23. The diameter of the cylindrical part 22 corresponds to the diameter of the sleeve 9 or pin 10, the width of the projection groove 23 corresponds to the congact crowd and the section of the groove 21. Each contact 9 or 10

is inserted into the cylinders, the impurity part 22 and is inserted with its groove 21 into the longitudinal groove 23. In the insulation plate 14 of the plug there are grooves 24 according to the number of contacts.

The depth of the groove 24 (Fig. 8) exceeds the diameter of the contact, and the width of the groove 24 corresponds to the thickness of the contact in the cross section of the groove 21; each sleeve 9 or pin 10 of the plant groove 21 into the groove 24. On the contact parts of the sleeves 9

Q and 10 of the plugs 10 are worn with their mounting holes insulator 8 sockets or insulator 15 plugs. The protrusions 25 and 26, made on the insulators 8 and 15 (Fig. 9), enter into the cylindrical holes 22 and the grooves 24 and are adjacent to the cylindrical part of the contacts 9 and 10, ensuring their reliable fixation. To secure the wires in the terminal part of the sleeve 9 and the pins 10, 27 are screwed into the threaded holes 20. The insulation plate 7 or 14 and the insulator 8 or 15 are connected to each other by 10MM with a rivet 28 or 29.

The described mounting design of the contacts ensures reliable fixation of the contacts of the connector in the longitudinal and transverse directions and eliminates the rotation of the wok 5 of the 1 U contact.
