Description

The invention relates to mechanical engineering and can be used in structures where it is required to disconnect the plug and socket of the electrical connector when divided into two parts of the body, for example, the aircraft on which they are fixed.

Known "Device for docking and undocking of electrical connectors between parts of products separated during operation" (patent RU No. 2 110 124 publ. 27.04.1998 IPC H01R 13/62).

This device contains an electrical connector made of a fixed part, rigidly fixed on the detachable part of the product, and a movable part docked with it, installed in a cylindrical housing, a fixation unit in the axial direction of the connector parts, a pyrotechnic pressure source installed in a socket connected to a sealed annular channel. The analogue has a hollow cylindrical sleeve, telescopically covering the housing of the movable part of the connector. An annular groove is made on the inner surface of the bushing, connected with a socket for a pyrotechnic pressure source. The undocking of the electrical connector is provided by the course of the detachable part of the product, or by means of a pyrotechnic pressure source.

The disadvantages of this analog are the complexity of the design, the lack of compensation for possible angular and transverse displacements of the separable parts of the product when the electrical connector is undocked by the course of the separable part of the product. When disconnecting the electrical connector by the course of the detachable part of the product, the presence of a pyrotechnic pressure source is not required.

As a prototype for the claimed invention, the "Docking point for electrical circuits of a detachable connection" was selected (patent RU No. 2 339 553 publ. 27.11.2008 Bull. No. 33 IPC B64G 1/64, H01R 13/52). This invention relates to rocket technology. The docking unit of the electrical circuits of the detachable connection contains the first and second parts of the connector, installed respectively on the detachable and onboard units with the help of brackets. The first and second parts of the connector are installed in housings placed inside a casing made in the form of a sleeve. The casing and body of the second part of the connector are provided with tails placed in the brackets by means of adapters with an outer spherical surface interacting with the inner spherical surface of said brackets. Mutual displacements of the separable and onboard blocks that occur during the separation of the blocks are compensated by the displacements of the adapters in the brackets using spherical hinges.

The disadvantages of this prototype are the complexity and bulkiness of the design, the presence of four parts associated with the manufacture of spherical surfaces. The external location of the junction of the electrical circuits of the detachable connection requires the sealing of the connector.

The objective of the claimed invention is to create a simple, compact assembly that provides reliable disconnection of the plug and socket of the electrical connector when divided into two parts of the housing on which they are fixed. In this case, the pins of the plug should not jam in the socket sockets with a possible angular and transverse displacement of the separable parts of the housing. The junction unit of the electrical connector is located inside the separable housing, and therefore, the sealing of the electrical connector is not required.

The solution of this problem is achieved by the fact that a roller is installed in the bracket for the fork with the help of screws, which can freely rotate in the holes of the bracket. A screw with a spherical head is screwed into the roller, which is installed in a bracket fixed on the detachable part of the body and having a hole with a longitudinal groove. The spherical head screw can freely rotate in the hole of the bracket, which makes it possible to screw the screw into the threaded hole of the shaft to press the plug to the socket during assembly and to ensure the disconnection of the plug and socket of the electrical connector when separating the housing. After pressing the plug to the socket, the screw is locked in the hole of the roller with a nut. Also, the screw can freely move in the hole of the bracket along the groove and rotate within the gap between the neck of the screw and the longitudinal groove in the bracket at a small angle (approximately ± 9°) and transverse displacement of the separable parts of the body. The bracket for the socket and the bracket with a screw with a spherical head, connected to the bracket for the plug by means of a roller with screws, are fixed on the body on different sides from the separation point.

The proposed junction of the electrical connector has a simple and compact design and allows you to compensate for possible angular and transverse displacements of the separable parts of the housing. If necessary, the plug and socket of the electrical connector can be interchanged, and the number of electrical connectors can be one, two or more.

The design of the disconnection unit of the plug and socket of the electrical connector when divided into two parts of the body on which they are fixed is shown in:

fig. 1 - junction of the plug and socket of the electrical connector before the separation of the body;

fig. 2 - junction of the plug and socket of the electrical connector after the separation of the housing;

fig. 3 - section A-A.

The undocking unit consists of the following structural elements:

1 - body;

1a - main body part;

1b - detachable part of the body;

2 - bracket;

3 - screw with a spherical head;

4 - roller;

5 - bracket for socket;

6 - bracket for plug;

7 - screw;

8 - nut;

9 - socket;

10 - fork;

11 - spherical head;

12 - pyrotechnic device;

13 - square shoulder;

14 - longitudinal groove;

15 - screw neck.

On the main part of the body 1a, a bracket for socket 5 is fixed with socket 9 fixed on it. screw 3 with a spherical head 11 is installed on the bracket 2. The screw 3 can freely rotate in the hole of the bracket 2 and move along the groove 14. The threaded part of the screw 3 passes through the longitudinal groove 14 of the bracket 2 and is screwed into the transverse threaded hole of the shaft 4 installed with the help of screws 7 in the fork bracket 6 so that the longitudinal axis of the shaft 4 is parallel to the longitudinal groove 14 of the bracket 2, and the shaft 4 can rotate freely about its longitudinal axis. Turning the screw 3 by the square collar 13 with a key ensures that the plug 10 is pressed against the socket 9. After that, the screw 3 is locked in the hole of the shaft 4 by the nut 8.

When separating body 1 using a pyrotechnic device 12, the bracket 2, together with the detachable part of the body 1b, pulls the bracket for the plug 6 through the screw 3 with a spherical head 11 and the roller 4, and the plug 10 and the socket 9 are undocked. 3 can move along the groove 14, and the shaft 4 together with the screw 3 can rotate on the screws 7 in the bracket for the fork 6 relative to the longitudinal axis of the shaft 4 within the gap between the neck 15 of the screw 3 and the longitudinal groove 14 in the bracket 2 at a small angle (approximately ± 9° sufficient to disconnect the plug 10 and socket 9 of the electrical connector.

The use of the proposed assembly ensures reliable disconnection of the plug and socket of the electrical connector when divided into two parts of the body on which they are fixed, without jamming the pins of the plug in the socket sockets in case of angular and transverse displacement of the separable parts of the body.

The claimed invention "Uncoupling the plug and socket of the electrical connector" has an inventive step, novelty and industrial applicability.
