Description

Technical Field

[0001] The invention belongs to the field of aviation connector design, and in particular relates to an easily detachable connector. Background Art

[0002] With the development of aviation electromechanical integration technology, connectors are increasingly used in the aviation field. As connectors are installed more and more densely, insufficient disassembly space has become a major problem.

[0003] Currently, connectors have screw connections, threaded connections, and push-pull self-locking connections. The disassembly process requires a large space, and sometimes it is necessary to pull the cable tail guide to remove the connector. When the connector separation force is large, it is easy to cause damage to the connector. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the connector is difficult to disassemble and damaged due to insufficient disassembly space, and to provide an easily disassembled connector suitable for use in a narrow space.

[0005] The technical solution of the present invention is: an easily detachable connector, the connector has an axially penetrating stepped hole in the male head, and has an I-shaped or T-shaped hole in the female head, or the connector has an I-shaped or T-shaped hole in the male head, and has an axially penetrating stepped hole in the female head;

[0006] The stepped hole has a large diameter portion on the connection side, and the small diameter portion is a threaded hole. A hexagonal nut is connected in the stepped hole, the head of the hexagonal nut is accommodated in the large diameter portion, and the end face of the rod is exposed and has a hexagonal hole.

[0007] The diameter of the I-shaped or T-shaped hole on the connection side is sufficient for the head of the hexagonal nut to enter, and the thrust of the hexagonal nut is borne by the hole shoulder.

[0008] Advantageously, a spacer block matching the hole shape is embedded in the “I”-shaped or “T”-shaped hole, and the spacer block bears the thrust of the hexagonal nut.

[0009] Advantageously, the cross-sectional shape of the cushion block is an I-shape or a T-shape.

[0010] Advantageously, the connecting end face of the male connector has a pin, the connecting end face of the female connector has a socket, and the size of the large diameter portion and the head size of the hexagonal nut meet the requirements for tight integration of the pin and the socket.

[0011] Advantageously, the male connector and the female connector are made of insulating material, and the pin and the socket are made of conductive material.

[0012] Advantageously, the hexagonal nut and the spacer are made of metal material.

[0013] Advantageously, the spacer is installed in an I-shaped or T-shaped hole by molding.

[0014] The advantages of the present invention are that the connector can occupy a small space so that the connector can be easily separated. When the connector separation force is large, there is no need to pull the cable tail to cause damage to the connector cable tail, thus saving space and improving the reliability of the connector.

[0020] The present invention is described in further detail below.

[0021] See also Figure 1 The embodiment of the easily detachable connector shown comprises a male head 1 , a female head 2 , a spacer 3 and a hexagonal inner nut 4 . The male head 1 is internally threaded with the hexagonal inner nut 4 , and the female head 2 is provided with the spacer 3 .

[0022] See Figure 2 The male connector 1 has an axial stepped hole 5, the hole diameter near the end face is larger than the inner hole diameter, the inner hole is a threaded hole, and the end face of the male connector 1 has a pin 6. The material of the male connector 1 is an insulating material.

[0023] See also Figure 3-4 The hexagonal nut 4 has an inner hexagonal hole 8 on the end face of its rod; after the inner hexagonal nut 4 is threadedly connected with the threaded hole of the male head 1, the inner hexagonal hole 8 is exposed, and the inner hexagonal nut 4 can be rotated by a hexagonal wrench. The inner hexagonal nut 4 is made of metal.

[0024] See also Figure 5The female head 2 has a hole with an I-shaped cross section, in which a spacer 3 is embedded. The spacer 3 is made of metal. The end face of the female head 2 has a socket 7. The spacer 3 is flush with the end face of the female head 2. When the male head 1 is combined with the female head 2, the spacer 3 contacts the head end face of the hexagonal nut 4. By rotating the hexagonal nut 4, the disassembly force between the male head and the female head can be applied to the spacer 3. The cross-sectional shape of the spacer 3 is I-shaped, which is adapted to the I-shaped hole of the female head 2. The spacer 3 and the female head 2 are installed by molding.

[0025] During installation, first use a screwdriver with a hexagonal head to screw the hexagonal nut 4 into the male head 1, and then press the male head 1 down so that the pin 6 fits tightly with the socket 7 of the female head 2 and is installed in place.

[0026] When disassembling, use a screwdriver with a hexagonal head to insert into the hexagonal hole 8 of the hexagonal nut 4, rotate the hexagonal nut 4, and the hexagonal nut 4 is kept stationary by the support force of the pad 3 in the female head, so that the male head 1 and the female head 2 are separated, and the pin 6 and the socket 7 are also easily separated. There is no need to pull the cable tail to cause damage to the connector cable tail, which saves space and improves the reliability of the connector.

[0027] In another embodiment, an I-shaped hole can be provided in the male head 1, in which a spacer block 3 is embedded. A threaded stepped hole 5 is provided in the female head 2, in which a hexagonal nut 4 is installed. The same effect of easy disassembly is achieved.
