Description

Technical Field

[0001] This utility model relates to the field of compressor wiring harness technology, specifically to an oil-resistant wiring harness assembly for compressors. Background Technology

[0002] In modern industrial production, compressors are a key piece of equipment widely used in refrigeration, air compression, chemical and many other fields. Their operating environment is often accompanied by a large amount of oil, which places stringent oil resistance requirements on the wiring harnesses connecting the various electrical components of the compressor.

[0003] Traditional compressor wiring harnesses have several shortcomings in terms of oil resistance. Most harnesses rely primarily on a simple outer sheath to protect against oil corrosion, with insufficient internal structural design to effectively prevent oil penetration. For example, the harnesses typically lack internal filler, and even if filler is present, it is ineffective against oil. Once the outer sheath is damaged due to mechanical friction, aging, or other reasons, oil can easily seep in, corroding the wire insulation and even the battery cells. This affects the harness's conductivity and safety, leading to frequent malfunctions in the compressor's electrical system.

[0004] In view of this, we propose an oil-resistant wiring harness assembly for compressors. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an oil-resistant wire harness assembly for compressors.

[0006] The technical solution of this utility model is:

[0007] An oil-resistant wiring harness assembly for compressors includes a central battery cell with an outer sheath. A support layer is fixedly installed on the outer wall of the sheath. A main protective layer is located outside the support layer, and several oil-absorbing layers are located outside the main protective layer. A barrier layer is located inside each oil-absorbing layer. The assembly also includes an outermost corrugated tube with a protective shell fixedly connected to both ends. A plug is electrically connected to both ends of the battery cell, with two plugs located within two separate protective shells. An oleophobic layer is located outside each protective shell. By combining multiple oil-absorbing and barrier layers, along with the outermost corrugated tube and protective shells, a multi-layered protection system is formed from the inside out. The outer wire sheath, support layer, and main protective layer can initially block oil intrusion; the oil-absorbing layers actively absorb penetrating oil; the barrier layers prevent further oil diffusion; the corrugated tube and protective shells resist external mechanical damage and oil erosion; and the oleophobic layer reduces external oil adhesion, significantly improving the oil resistance and service life of the wiring harness in the oily environment of the compressor.

[0008] As a preferred technical solution, an isolation layer is provided on the outer side of the main protective layer, and the isolation layer is tightly fitted with the innermost partition layer. The isolation layer can prevent oil from seeping in due to gaps between the main protective layer and the partition layer.

[0009] As a preferred technical solution, the inner side of the corrugated pipe is provided with a reinforced wear-resistant layer, which is tightly fitted to the inner ring wall of the corrugated pipe. This not only enhances the structural strength of the corrugated pipe but also improves its wear resistance.

[0010] As a preferred technical solution, the reinforced wear-resistant layer contains several layers of metal mesh, and the reinforced wear-resistant layer is tightly bonded to the outermost absorbent layer's outer ring wall. This significantly improves the tensile and impact resistance of the reinforced wear-resistant layer.

[0011] As a preferred technical solution, the protective shell includes two symmetrically arranged semi-shells, which are fixedly connected by a number of fixing screws. During assembly or maintenance, the protective shell can be opened by removing the screws to facilitate operation of internal components such as plugs, while forming a tight protective space when closed.

[0012] As a preferred technical solution, the protective shell includes a main body layer, an oleophobic layer disposed on the outer side of the main body layer, and an inner protective layer disposed on the inner ring wall of the main body layer, the inner protective layer being tightly fitted to the outer ring wall of the plug. The oleophobic layer on the outer side of the main body layer of the protective shell and the inner protective layer on the inner ring wall, with the inner protective layer tightly fitted to the outer ring wall of the plug, form multiple layers of protection for the plug.

[0013] As a preferred technical solution, the oil-absorbing layer has uniformly distributed honeycomb-shaped pores inside. This significantly increases the specific surface area of ​​the oil-absorbing layer, thereby improving its oil absorption capacity and oil absorption rate.

[0014] As a preferred technical solution, the support layer contains a plurality of axially arranged and uniformly distributed glass fiber filaments. This provides stable structural support for the wire harness. The glass fiber filaments have high strength and toughness, which enhances the bending and tensile resistance of the wire harness.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes a multi-layered structure combining oil-absorbing and barrier layers, along with an outermost corrugated pipe and protective shell, to form a multi-layered protection system from the inside out. The outer wire sheath, support layer, and main protective layer of the battery cell initially prevent oil intrusion; the oil-absorbing layer actively absorbs the infiltrated oil; the barrier layer prevents further oil diffusion; the corrugated pipe and protective shell resist external mechanical damage and oil erosion; and the oleophobic layer reduces external oil adhesion, significantly improving the oil resistance and service life of the wiring harness in the oily environment of a compressor.

[0025] An oil-resistant wiring harness assembly for a compressor includes a central battery cell 3, with an outer sheath 30 on the outer wall of the battery cell 3. A support layer 31 is fixedly installed on the outer wall of the sheath 30. A main protective layer 32 is provided outside the support layer 31, and several oil-absorbing layers 35 are provided outside the main protective layer 32. A partition layer 36 is provided inside each oil-absorbing layer 35. The assembly also includes an outermost corrugated pipe 1, with a protective shell 2 fixedly connected to both ends of the corrugated pipe 1. A plug 4 is electrically connected to both ends of the battery cell 3, with two plugs 4 located inside two protective shells 2 respectively. An oleophobic layer 22 is provided on the outer side of the protective shells 2. By combining multiple layers of oil-absorbing layers 35 and partition layers 36, along with the outermost corrugated pipe 1 and protective shells 2, a multi-layered protection system from the inside out is formed. The wire sheath 30, support layer 31 and main protective layer 32 outside the battery cell 3 can initially block the intrusion of oil. The oil-absorbing layer 35 can actively absorb the infiltrated oil. The barrier layer 36 can prevent the oil from spreading further. The corrugated pipe 1 and protective shell 2 can resist external mechanical damage and oil erosion. The oleophobic layer 22 can also reduce the adhesion of external oil, which greatly improves the oil resistance and service life of the wire harness in the oily environment of the compressor.

[0026] In a preferred embodiment, an isolation layer 33 is provided on the outer side of the main protective layer 32, and the isolation layer 33 is tightly fitted with the innermost partition layer 36. The isolation layer 33 can prevent oil from seeping in due to gaps between the main protective layer 32 and the partition layer 36.

[0027] As a preferred embodiment, the inner side of the bellows 1 is provided with a reinforcing wear-resistant layer 34, which is tightly fitted to the inner ring wall of the bellows 1. This not only enhances the structural strength of the bellows 1 but also improves its wear resistance.

[0028] In a preferred embodiment, the reinforced wear-resistant layer 34 contains several layers of metal mesh, and the reinforced wear-resistant layer 34 is tightly bonded to the outermost absorbent layer's outer ring wall. This significantly improves the tensile and impact resistance of the reinforced wear-resistant layer 34.

[0029] In a preferred embodiment, the protective shell 2 includes two symmetrically arranged semi-shells 20, which are fixedly connected by a plurality of fixing screws 21. During assembly or maintenance, the protective shell 2 can be opened by removing the screws to facilitate operation of internal components such as the plug 4, while forming a tight protective space when closed.

[0030] In a preferred embodiment, the protective shell 2 includes a main body layer 24, an oleophobic layer 22 disposed on the outer side of the main body layer 24, and an inner protective layer 23 disposed on the inner ring wall of the main body layer 24. The inner protective layer 23 is tightly fitted to the outer ring wall of the plug 4. The oleophobic layer 22 on the outer side of the main body layer 24 of the protective shell 2 and the inner protective layer 23 on the inner ring wall, with the inner protective layer 23 tightly fitted to the outer ring wall of the plug 4, form multiple layers of protection for the plug 4.

[0031] As a preferred embodiment, the oil-absorbing layer 35 has uniformly distributed honeycomb-shaped pores inside. This significantly increases the specific surface area of ​​the oil-absorbing layer 35, thereby improving its oil absorption capacity and oil absorption rate.

[0032] In a preferred embodiment, the support layer 31 contains a plurality of axially arranged and uniformly distributed glass fiber filaments 3. This provides stable structural support for the wire harness. The glass fiber filaments have high strength and toughness, which enhances the bending and tensile strength of the wire harness.

[0033] When the compressor is running, the oil-resistant wiring harness assembly of this utility model provides protection through multiple structural synergies. The wire sheath 30, support layer 31, and main protective layer 32 outside the central battery core 3 form an initial oil barrier, with the glass fiber filaments of the support layer 31 providing stable support. A small amount of oil seeps in but is blocked by the gaps in the isolation layer 33, and then absorbed by the oil-absorbing layer 35 with honeycomb-like pores and blocked by the barrier layer 36. The outer corrugated tube 1 and the inner reinforced wear-resistant layer 34 with metal mesh resist mechanical damage and friction. The protective shells 2 at both ends are closed by the semi-shell 20 to form a tight space. The outer oleophobic layer 22 reduces oil adhesion, and the inner protective layer 23 seals the gaps in the plug 4. Overall, by blocking, absorbing, and isolating oil and resisting mechanical damage, the assembly ensures stable operation of the wiring harness and improves its oil resistance life.
