Description

Technical Field

[0001] The invention relates to the technical field of aviation plugs, and in particular to an aviation plug adapted for a light chain. Background Art

[0002] Aviation plug is a kind of connector, which originated from the military industry, hence the name, referred to as aviation plug. Aviation plug is an electromechanical component that connects electrical circuits, so its own electrical parameters are the first thing to consider when choosing an aviation plug.

[0003] After multiple plugging and unplugging of existing wiring harnesses, the conductive copper sheet will be worn out, resulting in poor contact between the conductive copper sheet and the conductive column. At the same time, after long-term use, the surface of the copper sheet will be oxidized to increase resistance, thereby increasing heat. Therefore, the conductive copper sheet needs to be replaced, but it is troublesome to replace the copper sheet. Summary of the invention

[0007] In practical applications, the device is provided with a locking assembly, and the movable cylinder in the locking assembly is squeezed by the mounting cylinder, so that the airbag is inflated, and the airbag is expanded, and the wire bundle is squeezed, so as to constrain the position of the wire bundle and prevent the wire from falling off due to squeezing the wire bundle to move;

[0008] The device is provided with a conductive component. After taking out the second connecting piece, the second connecting piece and the second mounting plate are disassembled, and then the conductive cylinder is taken out, so that it is convenient for the staff to replace the conductive cylinder and effectively avoid poor contact between the conductive cylinder and the conductive column in the first connecting piece.

[0009] Further, the locking assembly includes a movable cylinder slidably connected to the connecting cylinder, a plurality of groups of spring telescopic rods are installed at one end of the movable cylinder, one end of each of the spring telescopic rods is connected to a hose, the other end of each of the hoses is commonly connected to an airbag, the periphery of the airbag is pasted on the inner wall of the connecting cylinder, and a friction plate or glue can be pasted on the surface of the airbag;

[0010] In actual application, the device is provided with a locking assembly, which squeezes the movable cylinder by the mounting cylinder, and the movable cylinder squeezes the spring telescopic rod, thereby injecting the gas inside the spring telescopic rod into the hose, and the air then enters the airbag from the inside of the hose, thereby inflating the inside of the airbag, and then expanding the airbag, thereby squeezing the wire bundle, and further constraining the position of the wire bundle to avoid squeezing the wire bundle to move and cause the wires to fall off.

[0011] Furthermore, the connecting tube is arranged in a trumpet shape, a rubber ring is fixedly arranged at one end of the connecting tube with a small opening, the rubber ring is fitted with the surface of the wire harness, and a retaining ring is arranged on the side of the airbag away from the rubber ring;

After replacing the conductive tube, the staff inserts the new conductive tube into the through hole, and then installs the second mounting plate on the outer wall of the second connecting member. Then the staff uses tools such as a syringe to inject the conductive liquid into the cavity between the sealing plate and the joint through the sealing plate. After the injection is completed, since the sealing plate is made of tough material, the injection hole can self-repair and the conductive liquid will not leak.
