[0032] In order to clearly and completely describe the objectives, technical solutions of the present invention and make the advantages more clearly understood, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0033] Example 1, please refer to Figures 1-12 , the present invention provides a technical solution: an air-conditioning compressor wiring harness that is convenient for docking, including a connecting wiring harness 1 and a telescopic bellows 11. The two ends of the telescopic bellows 11 are connected to the connecting wiring harness 1 through a first heat-shrinkable tube 12. A multi-core wire 13 is arranged inside the connecting wiring harness 1. One end of the multi-core wire 13 is fixedly connected with a circular ring terminal 14. Heat-shrinkable tubes 121 are respectively arranged at both ends of the connecting wiring harness 1. A gland head mechanism 2 is arranged outside the connecting wiring harness 1. One end of the gland head mechanism 2 is movably connected with a compressor female connector 3. The compressor female connector 3 is arranged at the IP interface position of the air-conditioning compressor. The gland head mechanism 2 includes a threaded annular sleeve 21 and a gland head body 22. An externally convex thread 210 is fixedly added to the outer surface of the threaded annular sleeve 21. The outer surface of the externally convex thread 210 is threadedly connected with the inner wall of the gland head body 22. An auxiliary tightening component is arranged inside the threaded annular sleeve 21. A tensioning and locking component is arranged at one end of the gland head body 22. The tensioning and locking component includes a shrinkable threaded sleeve plate 23 and a locking nut 24. An end waterproof component is arranged at the end of the gland head body 22 away from the compressor female connector 3. The end waterproof component includes an externally connected waterproof boss 25;

[0034] In this embodiment, the circular ring terminal 14 is used to connect with the end of the multi-core wire 13, replacing the traditional quick-insert terminals to be inserted into the compressor. This avoids the influence of jitter on the insertion effect of the terminals. And by adding the gland head mechanism 2 to the connecting wiring harness 1, the cable is tightly connected to the docking device, preventing the cable from loosening or falling off due to external forces during use, and playing a role in the sealing and fastening of the connection with the air-conditioning compressor device. Through the cooperation of the tensioning and locking component and the end waterproof component, multiple protections are carried out on the IP position. With the setting of the auxiliary tightening component, it can prevent the cable from randomly undergoing radial torsion and axial displacement, thereby protecting the cable skin from damage and extending the overall service life; further solving the problems of single connection method between the existing cable and the gland head, inconvenient installation and disassembly, and poor protection effect.

[0035] Embodiment 2. On the basis of Embodiment 1, in order to realize the tightening of the threaded annular sleeve 21 and the gland body 22, this embodiment further proposes that a threaded docking platform 211 is fixedly installed at one end of the threaded annular sleeve 21. The outer surface of the threaded docking platform 211 is threadedly connected to the inner surface of the compressor female connector 3. A terminal rubber waterproof ring 222 is provided at the end of the threaded annular sleeve 21 away from the threaded docking platform 211. The terminal rubber waterproof ring 222 has a circular convex ring structure. A waterproof membrane 2221 is fixedly connected to the outer end of the terminal rubber waterproof ring 222, and the terminal rubber waterproof ring 222 is fixedly installed on the inner ring surface of the gland body 22. An auxiliary force-bearing assembly is provided on the outer surface of the gland body 22. The auxiliary force-bearing assembly includes a force-bearing nut 221. The inner ring surface of the force-bearing nut 221 is fixedly connected to the outer surface of the gland body 22. An embedding groove 2210 is formed on the outer surface of the force-bearing nut 221, and a soft rubber convex strip 2211 is movably embedded in the inner surface of the embedding groove 2210.

[0036] In this embodiment, the threaded annular sleeve 21 is first sleeved from one end of the connecting wire harness 1. One end of the threaded annular sleeve 21 is adaptively docked with the plug-in connector compressor female connector 3 on the air conditioner compressor. One end of the threaded annular sleeve 21 is connected to the terminal rubber waterproof ring 222 and the waterproof membrane 2221 to protect the skin of the connecting wire harness 1. Then, the entire gland body 22 is inserted from the same end of the connecting wire harness 1. When the two are close, the outer part of the force-bearing nut 221 is held by hand to screw the gland body 22. Under the action of thread adaptation, the internal thread groove of the gland body 22 is threadedly adapted to the convex thread 210 part on the surface of the threaded annular sleeve 21. When the gland body 22 is screwed in place, the terminal rubber waterproof ring 222 at the inner side of the end of the gland body 22 close to the external waterproof boss 25 abuts against the end of the threaded annular sleeve 21 away from the compressor female connector 3. The reason for adding structures such as the terminal rubber waterproof ring 222 and the waterproof membrane 2221 at the end of the gland body 22 is to play a role in waterproofing and dustproofing the inside of the threaded annular sleeve 21. It should be noted that the terminal rubber waterproof ring 222 is made of soft and elastic nitrile material throughout, which can not only play a role in waterproofing and dustproofing, but also strengthen the protection of the cable clamping and slow down the damage of the outer skin.

[0037] It should also be noted that the force-bearing nut 221 is connected to the outside of the gland body 22, and the embedding groove 2210 accommodates the soft rubber convex strip 2211. When the operator rotates the gland body 22, the hand receives force by contacting the soft rubber convex strip 2211, ensuring that the screwing is more labor-saving without the need to use external tools.

[0038] Embodiment 3, on the basis of embodiment 2, in order to realize the limiting of the connection harness 1, this embodiment further proposes that the auxiliary tightening assembly includes an inner ring 26, the inner ring 26 is fixedly mounted on the inner ring surface of the threaded annular sleeve 21, and the outer surface of the inner ring 26 is fixedly mounted with reinforcing ribs 261, and the reinforcing ribs 261 are arranged in a circular array about the central axis of the inner ring 26, and one end of the inner ring 26 is fixedly connected with a clamping head 262, and the clamping head 262 has a feather-like structure, and the outer surface of the clamping head 262 is movably connected to the inner ring surface of the end rubber waterproof ring 222;

[0039] In this embodiment, after the gland body 22 and the threaded annular sleeve 21 are butt-jointed and locked, the inner sleeve 26 connected to the inner side is sleeved on the outside of the connecting harness 1, and the clamping head 262 here is set as a feather-shaped annular structure, referring to Figures 10-11 It can be seen that when the cable gland body 22 drives the end rubber waterproof ring 222 to move toward one end of the compressor female connector 3, the inner ring of the end rubber waterproof ring 222 contacts the clamping head 262, so that the threaded annular sleeve 21 and the cable gland body 22 are docked and installed, while ensuring that the clamping head 262 is pressed tightly against the outer skin of the inner connecting wire harness 1, further ensuring that the connecting wire harness 1 will not be arbitrarily radially twisted and axially displaced, thereby protecting the cable skin from damage.

[0040] Embodiment 4: On the basis of embodiment 3, in order to achieve the waterproof effect on the end of the gland body 22, this embodiment further proposes an end waterproof assembly, the external waterproof boss 25 is fixedly installed at one end of the gland body 22 away from the compressor female joint 3, the inner ring surface of the external waterproof boss 25 is provided with a receiving groove 251, the inner surface of the receiving groove 251 is embedded with a sealing rubber ring 252, and the central inner surface of the sealing rubber ring 252 is provided with an extrusion groove;

[0041] In this embodiment, refer to Figures 4-5 As shown, when the gland body 22 is adapted and connected with the threaded annular sleeve 21, the external waterproof boss 25 at one end of the gland body 22 is designed with an inwardly inclined opening, which can ensure that the sealing rubber ring 252 gradually contacts the surface of the connecting harness 1. The sealing rubber ring 252 first contacts the waterproof membrane 2221. The sealing rubber ring 252 here plays a role in preventing the cable from slipping and loosening. At the same time, the special structural design of the external waterproof boss 25 can avoid friction and bending at the contact position of the connector, thereby further enhancing the protection effect of the connecting harness 1. It should be noted that the receiving groove 251 here accommodates the sealing rubber ring 252, and the extrusion groove on the inner side of the sealing rubber ring 252 can provide space for the deformation of the sealing rubber ring 252.

[0042] Embodiment 5, on the basis of embodiment 4, in order to realize the bidirectional clamping between the threaded annular sleeve 21 and the gland body 22, this embodiment further proposes a tension locking assembly, one end of the shrinking thread sleeve 23 is fixedly connected to the end of the gland body 22 away from the external waterproof boss 25, and reserved grooves 230 are evenly provided on the inner wall of the shrinking thread sleeve 23, and the reserved grooves 230 are distributed in a circular array about the central inner surface of the shrinking thread sleeve 23, and a protective gasket 231 is attached to the inner ring surface of the shrinking thread sleeve 23; the inner surface of the locking nut 24 is threadedly connected to the outer surface of the shrinking thread sleeve 23, and the outer surface of the locking nut 24 is provided with a thumb groove 240, and a silicone gasket 2401 is arranged on the inner side of the thumb groove 240; a sealing gasket 241 is movably connected to one side of the locking nut 24, and the outer surface of the sealing gasket 241 is movably abutted with a sealing gasket 1 220, and the sealing gasket 1 220 is sleeved and installed on the outer surface of the gland body 22;

[0043] In this embodiment, the threads of the threaded annular sleeve 21 and the gland body 22 are adapted and clamped, and the shrinking threaded sleeve plate 23 added to the end of the gland body 22 away from the external waterproof boss 25 is sleeved to the outside of the threaded annular sleeve 21. At this time, the thread on the surface of the shrinking threaded sleeve plate 23 is adapted to the thread on the inner wall of the locking nut 24 by screwing the locking nut 24. It is worth noting that reserved grooves 230 are evenly opened on the inner wall of the shrinking threaded sleeve plate 23, so that the inner diameter of the shrinking threaded sleeve plate 23 can be gradually reduced when the locking nut 24 and the shrinking threaded sleeve plate 23 are screwed together, so as to cooperate with the waterproof The provision of the protective gasket 231 enhances the flexible protection of the surface of the threaded annular sleeve 21 to avoid damage; and through the provision of the sealing gasket 241 and the sealing gasket 1 220, the sealing performance of the locking nut 24 on the gland body 22 is enhanced. It should be noted that thumb grooves 240 are evenly opened on the surface of the locking nut 24 to facilitate the operator's thumb to apply force, and a silicone gasket 2401 is installed on the inner side of the thumb groove 240 to protect the thumb, so that the locking nut 24 can be tightened more labor-saving and ensure that the wiring harness and the air-conditioning compressor interface are more precisely connected.

[0044] Embodiment Six, the present invention also provides a usage method of an air-conditioning compressor wiring harness that is convenient for docking. The specific operations are as follows: Step One: First, lock the multi-core wire 13 on the frequency converter and the compressor for fixation. Then, first sleeved the threaded annular sleeve 21 from one end of the connecting wire harness 1. One end of the threaded annular sleeve 21 is adaptively docked with the female mating connector 3 on the air-conditioning compressor. The end connecting end rubber waterproof ring 222 and the waterproof diaphragm 2221 of the threaded annular sleeve 21 protect the skin of the connecting wire harness 1. Then, the gland head body 22 is inserted into the same end of the connecting wire harness 1 as a whole. When the two are close, hold the outside of the force-bearing nut 221 and twist the gland head body 22. Under the action of thread adaptation, the internal thread groove in the gland head body 22 is partially thread-adapted to the convex thread 210 on the surface of the threaded annular sleeve 21. When the gland head body 22 is screwed in place, the end rubber waterproof ring 222 inside the end of the gland head body 22 close to the external waterproof boss 25 abuts against one end of the threaded annular sleeve 21 away from the compressor female mating connector 3. Step Two: When the gland head body 22 and the threaded annular sleeve 21 are docked and locked, the inner sleeve ring 26 connected inside is sleeved on the outside of the connecting wire harness 1. When the gland head body 22 drives the end rubber waterproof ring 222 to move forward towards the compressor female mating connector 3, the inner ring of the end rubber waterproof ring 222 abuts against the clamping head 262. In this way, while the threaded annular sleeve 21 and the gland head body 22 are docked and installed, it is ensured that the clamping head 262 tightens the outer skin of the inner connecting wire harness 1. Step Three: After the gland head body 22 and the threaded annular sleeve 21 are adaptively connected, the external waterproof boss 25 at one end of the gland head body 22 is designed with an inwardly inclined opening, which can ensure that the sealing rubber ring 252 gradually abuts against the surface of the connecting wire harness 1. The sealing rubber ring 252 first abuts against the waterproof diaphragm 2221. Here, the sealing rubber ring 252 plays a role in preventing the cable from slipping and loosening. Step Four: The threaded annular sleeve 21 and the gland head body 22 are thread-adapted and clamped. The shrinkage threaded sleeve plate 23 added at one end of the gland head body 22 away from the external waterproof boss 25 is sleeved on the outside of the threaded annular sleeve 21. At this time, by twisting the locking nut 24, the thread on the surface of the shrinkage threaded sleeve plate 23 is thread-adapted to the inner wall thread of the locking nut 24, so as to realize the final fixation of the gland head mechanism 2.
