Description

The invention relates to electrical engineering, in particular to electrical connectors that provide remote undocking of the plug and socket of the electrical connector.

A device for disconnecting the current collector from the electrical network according to the patent of Russia No. 2096878 with a priority of 10.01.1996, containing a socket and a plug. An electromagnet control winding is installed inside the plug housing. The undocking occurs when current is passed through the winding of the electromagnet. The disadvantage of this device is that with a large number of contacts of the electrical connector, the dimensions of the device will be very significant.

Closest to the invention in technical essence is a device for docking-undocking electrical connectors between parts of products that are shared during operation according to Russian patent No. 2110124 with a priority of 02/05/1998.

The device contains separable parts — a plug and socket, a spring holding the plug and socket in a docked state, o-rings, a spring ring and a pyrotechnic pressure source.

A disadvantage of the known device is the complexity of the design, low-tech manufacturing due to the lateral arrangement of the pyrotechnic device, because of this there is a likelihood of a skew when undocking the shared parts. In addition, the contact fields of the parts to be separated are not protected from the external environment after their separation.

The objective of the invention is to simplify the design, increase reliability and protect the contact fields of the parts to be separated from the effects of the external environment after separation. This problem is solved in that the device comprises a housing, inside of which are plug and socket parts. A piston is installed on the fork part, which is rigidly connected to the socket part at one end and connected to a threaded sleeve at the other end, which prevents the piston from moving and, accordingly, the fork and socket parts are separated in the initial position. A spring is installed on the outlet, preventing the docking and outlet parts from joining after separation.

The invention is illustrated by drawings, where:

- figure 1 shows a General view of the device in a docked state;

- figure 2 shows the device after separation of the plug and socket parts.

The device comprises a housing 1, inside of which the male part 2 and the outlet part 3 are located, the male part 2 is rigidly connected to the housing 1. Inside the insulator 4 of the male part 2, a diaphragm 5 is pressed into which the stand 6 is screwed. A pyrotechnic pressure source 7 is installed in the stand 6 through the gasket 8, as well as a nut 9 with an opening for a screw 10, which holds the piston 11 from moving and, accordingly, from an arbitrary undocking of the device. The base of the nut 9 with the hole for the screw 10 is made with a bottom thickness designed to break through the pressure of the gases of the pyrotechnic pressure source 7.

The other end of the piston 11 is connected by a screw 12 to the socket part 3. The piston has a step 13, and there is also a step 14 in the internal channel of the rack 6. The distance between the steps 13 and 14 is greater than the length of the pins of the fork part 1.

To eliminate the breakthrough of gases from the pyrotechnic pressure source 7, a sealing ring 15 is installed in the piston.

The socket part 3 is made of two detachable insulators 16 and 17. In the insulator 16 two guide bushings 18 with threaded holes are pressed into, where the screws 19 are fastened, fastening the insulators 16 and 17. The flat spring tabs 20 are fastened with the same screws 19. In the insulator 16 in the center a sleeve 23 is pressed in, which is in contact with the insulator 17 and connected via a screw 12 to the piston 11.

In the housing 1, two grooves are made 21. For visual inspection of the docking of the plug and socket parts in the housing 1, two inspection holes 22 are made.

The docking device is as follows. The sleeve 9 is screwed into the stand 6 until it stops, through which a piston 11 is pressed against it by a screw 10. After that, a pyrotechnic pressure source 7 is installed. The outlet part 3 is connected to the fork part 2, the final docking is carried out with the help of screw 12. Visual inspection of the fork dock and outlet parts are carried out through holes 22.

When a signal is supplied to the pyrotechnic pressure source 7, a pressure appears in cavity A, under the influence of which the base of nut 9 breaks. After breaking through the base of nut 9, the piston 11 moves under pressure until the ledge 13 of the piston 11 abuts against the ledge 14 of the rack 6. Since the piston 11 is rigidly connected with the outlet part 3, then along with the stroke of the piston 11 there is an undocking-departure of the outlet part 3 from the fork part 2.

At the end of the undocking of the outlet part 3, the flat springs of the petals 20 enter the grooves 21 made in the housing 1, thereby preventing the outlet of the outlet part 3 and, accordingly, the docking part 3 and the plug part 2 are mated after undocking, this position of the device is shown in FIG. .2.

A similar embodiment of the device for docking and undocking electrical connectors can improve reliability and simplify the design.
