RU62479U1 - COMMUNICATION CABLE FOR AIRCRAFT WITH CONTROL APPARATUS - Google Patents

Abstract

A utility model for a communication cable between an aircraft and control equipment relates to electrical engineering.

The communication cable contains several 50-pin electrical connectors of the same type, connected by cable branches to a multi-pin electrical connector (450-pin). Cable branches are made of insulated shielded wires and cables. Typical electrical connectors have cable entries that contain a rack with a two-sided cutout, a sleeve is connected to the rack, onto which screen braids of wires and cables are soldered. The stand is closed from the outside by a casing, a tightened nut, screwed onto the sleeve. Holes are made in the casing, in which rivets are installed that are electrically connected with screen braids soldered to the sleeve. Cable branches and part of typical electrical connectors are covered with heat-resistant tape, the ends of which are fixed with a bandage of threads.

Description

The utility model relates to the field of electrical engineering, in particular, to communication cables.

A utility model is known according to Russian patent No. 34800 of June 30, 2003 for a jumper to cable racks and travel boxes containing a plug, a flexible cable, a contact bolt, insulating sleeves and nuts, which are placed on a plug having an additional section with a thread.

Closer in technical essence to the proposed utility model is a utility model according to Russian patent No. 50040 dated 05/14/05 for the cable connecting the battery and starter. The connection cable consists of a wire and lugs for connecting to the battery terminal and connecting to the starter. The tip for connecting to the battery is formed by a split sleeve with a truncated cone-shaped inner surface, and the tip for connecting to the starter is L-shaped.

The disadvantage of this cable connection is that this cable can connect only two objects of one conductive core.

The objective of the proposed utility model is to provide cable communication of many parameters of the aircraft with the control equipment through one electrical connector, this is due to the fact that the aircraft is separated from the control equipment by a tight wall, and it is necessary to have a minimum of tight passages through this wall.

This problem is solved by the fact that eight 50-contact electrical connectors are connected by cable branches to one special electrical connector, which is connected to a sealed special electrical connector passing through an airtight wall.

The essence of the utility model is illustrated by drawings, where:

- figure 1 shows a communication cable,

- figure 2 - in section aa shows a cable entry with an electrical connector.

The communication cable between the aircraft and control equipment contains a multi-pin electrical connector 1 (450-pin) connected by cable branches 2 with the same type of electrical connectors 3 (50-pin). On one of the cable branches 2 there is a tag 4 with the name of the communication cable.

Each cable branch 2 is made of a set of insulated shielded wires 5 of different sections. A tube 6 of insulating material is installed on the sets of wires 5, at the ends of the tube 6 is fixed with a bandage 7 of threads that are impregnated with glue, for example VK-9. The wiring harness with the applied bandage 7 is located inside the sleeve 8, which is connected to the rack 9, which in turn is connected to the electrical connector 3. In the rack 9, cutouts are made on both sides to provide access to the shanks 10 of the electrical connector 3. Outside, the rack 9 is closed by a casing 11, which is fixed by a nut 12. In the casing 11, holes are made where rivets 13 are installed, with which the casing 11 is connected to the screen braids through the tips 14 and wires 15. Screen braids are soldered to the sleeve 8. At the ends of the casing 11, as well as at the point of exit from the nut 12, glue is applied, for example, VK-9. On top of all cable branches 2, a coating of heat-resistant tape 16 is applied, for example, LETSAR. The same tape 16 wound part of the nut 12 and part of the cable branch 2 in the area of entry to the nut 12. The tape 16, applied to the nut 12 and the cable branch 2, is fastened with yarn bandages 17, 18 and is also impregnated with glue.

Assembly cable entry as follows.

Screw the rack 9 onto 3, onto which the sleeve 8 is installed. The end of the cable branch 2 with the bandage 7 applied and the cut wires 5 and 15 is led into the hole of the sleeve 8. Screen braids are soldered to the sleeve 8,

solder the wires 5 to the shanks 10, then install the casing 11, while prior to the final installation of the casing 11, rivets 13 with tips 14 are installed in the holes and riveting is carried out. When the casing 11 is finally installed, glue is applied to its ends and the casing is pressed with the nut 12. Then glue is applied to the nut 12 and to the cable branch 2 at the place of entry into the nut 12. After that, part of the nut 12 and part of the cable branch 2 are wrapped with heat-resistant tape 16. At the ends of the tape install bandages of threads 17, 18 and impregnate them with glue.

This embodiment of the communication cable of the aircraft with the control equipment allows to reduce the number of tight passages through the wall, and the proposed cable entry provides the convenience of mounting the wires when soldering to the electrical connector, reliable grounding of the screen braids of the wires and provides dust and moisture protection of the internal volume of the electrical connector.
