Description

Technical Field

[0001] The utility model relates to the technical field of disassembly and assembly tools, in particular to a round aviation plug disassembly and assembly wrench in a narrow space, which is suitable for disassembling and assembling aviation plugs in a narrow space that cannot be touched by hands or conventional tools. Background Art

[0002] Aviation plugs are components that connect electrical circuits and are widely used in circuit connections between various electrical equipment. Round aviation plugs are generally connected by threads. When connected, the aviation plug uses the threads on the socket or plug side to achieve reliable fastening between the plug and the socket. When the round aviation plug is inserted, in order to ensure the reliable sealing of the aviation plug and the minimum contact resistance between the plug and the socket, the connecting nut of the aviation plug must be tightened in place; when disassembling, the connecting nut must be loosened in place so that the plug and the socket can be separated.

[0003] Generally, aviation plugs can be tightened directly by hand, or clamped and tightened with general tools such as pliers and hawkbill pliers. However, in some narrow and restricted areas, it is impossible to clamp the aviation plug with hands or conventional tools, or it is inconvenient to apply force after clamping. In this case, it is very easy to cause the aviation plug to be loosely connected, which in turn causes faults such as no contact, virtual connection, and high contact resistance between the pin and the socket. Currently, there is no suitable disassembly and assembly tool for this situation. Utility Model Content

The axial opening 101 can avoid the wiring harness at the end of the aviation plug and be directly sleeved on the connecting nut of the aviation plug. There is no need to set an additional clearance groove to avoid the wiring harness, which is convenient for operation.

[0033] A first clamping surface 102 is provided on the inner surface of one side of the open circular ring 1 , and a notch 104 is provided on the side of the open circular ring 1 away from the first clamping surface 102 . The notch 104 passes through both the inner and outer sides of the open circular ring 1 .

[0034] A hinged ear 103 protruding outward is provided on the outer side of the open circular ring 1, and the hinged ear 103 is located next to the notch 104. One side of the movable claw 2 is hinged to the hinged ear 103 through the hinge shaft 3. The movable claw 2 and the notch 104 are located on the same side, and a second clamping surface 202 is provided on the side of the movable claw 2 close to the notch 104. During use, the movable claw 2 can rotate so that the second clamping surface 202 enters the open circular ring 1 from the notch 104. When the second clamping surface 202 enters the open circular ring 1, the first clamping surface 102 and the second clamping surface 104 can clamp the connecting nut 4 of the circular aviation plug.

[0035] The movable claw 2 is provided with a connection hole 201 for connecting with an external tool. The connection hole 201 of this embodiment is a square hole, which is a through hole. In other embodiments, the connection hole 201 can also be other shapes, such as a hexagonal hole.

When disassembling, the open ring 1 is put on the connecting nut 4 of the circular aviation plug, the connecting hole 201 is connected to the external tool, and then rotated clockwise, so that the first clamping surface 102 and the second clamping surface 202 clamp the connecting nut 4 and drive the connecting nut 4 to rotate clockwise.

[0041] 2. When the connecting nut 4 of the circular aviation plug needs to be turned counterclockwise, the clamping position of the circular aviation plug disassembly wrench will be as follows: Figure 4 As shown, the movable claw 2 will be located on the left side of the open ring 1 when viewed from a top view.

[0042] The utility model can be used for the disassembly and assembly of aviation plugs that are located in narrow and restricted areas and cannot be touched by hands and conventional tools. It can reliably and directly clamp the connecting nut 4 of the aviation plug to ensure that the rotational force is reliably transmitted to the connecting nut 4. Adapter rods of different lengths can be used according to regional conditions to complete the disassembly and assembly of aviation plugs in areas of different depths. The clamping part is conveniently designed and can be operated with one hand. The two clamping surfaces and the hinge shaft 3 form a balanced force to ensure that the aviation plug is balanced in all directions and is not easy to slip. If necessary, a torque device can be connected to achieve the application of a specific torque for the disassembly and assembly of the aviation plug. The axial opening 101 of the open ring 1 can avoid the wiring harness at the end of the aviation plug and be directly sleeved on the connecting nut 4 of the aviation plug. There is no need to set an additional clearance groove to avoid the wiring harness, which is convenient for operation. The utility model can realize reliable disassembly and assembly of aviation plugs in narrow and restricted areas, ensure the connection reliability of pins and sockets in the plug and socket, and compared with general tools, can effectively protect the aviation plug from damage and greatly improve the efficiency of disassembly and assembly.
