Description

Technical Field

[0001] The utility model relates to the technical field of spring wire harnesses, and particularly relates to a highly protective spring wire harness and an aviation connector plug. Background Art

[0002] At present, the spring wire harnesses on the market have a single-layer wire skin and are mostly used in working conditions with relatively good environments, that is, the requirements for the anti-corrosion, wear resistance, fatigue resistance and other properties of the spring wire are relatively low. However, in the field of sanitation vehicles at present, especially the working environment of kitchen waste vehicles is relatively complex. The spring wire needs to withstand high-intensity and high-frequency work. At the same time, the oil stains around the wire harness are highly corrosive. Conventional spring wires cannot meet this environment, so a spring wire with relatively high performance is needed to deal with this situation. Content of the Utility Model

[0003] The purpose of the utility model is to provide a highly protective spring wire harness and an aviation connector plug with good corrosion resistance, strong reliability and capable of withstanding high-intensity and high-frequency work.

[0004] A highly protective spring wire harness for an aviation plug connector. The spring wire harness includes a spring part and a connector part. Both ends of the spring part are connected to the connector part. The connector part includes a protective outer layer, a protective inner layer, a shielding layer, a protective layer and a wire layer. The protective layer wraps around the outer periphery of the wire layer, the shielding layer wraps around the outer periphery of the protective layer, the protective inner layer wraps around the outer periphery of the shielding layer, and the protective outer layer wraps around the outer periphery of the protective inner layer.

[0005] In the above solution, the wire layer is used for current or electromagnetic transmission. The protective layer is used to protect the wire layer, which can effectively protect the electrical system and ensure the reliability of the wire layer. The shielding layer is used to reduce the electromagnetic interference from the outside to the wire layer. The protective inner layer is made of a material with excellent chemical stability and corrosion resistance, which can resist the erosion of various chemical substances. The protective outer layer is made of a material with high durability and flexibility. The combination of the protective inner layer and the protective outer layer can not only resist the harsh and complex working environment but also meet the requirements of frequent stretching operations. The aviation plug connector has excellent waterproof and dustproof performance, and can automatically lock the connector part, which can avoid the spring wire harness from falling off, has high connection strength, and is suitable for the working environment of operation vehicles such as sanitation vehicles or engineering vehicles.

[0006] Further, the material of the protective outer layer is TPU.

[0007] In the above solution, the Chinese name of TPU is thermoplastic polyurethane elastomer rubber, which has strong oil resistance, wear resistance, high elasticity, anti-aging and other characteristics, and is very suitable for the outer protection of the spring wire harness.

[0008] Further, the material of the protective inner layer is PVC.

[0009] In the above solution, the PVC material has good tolerance to a variety of chemical substances and can resist the erosion of chemical substances such as acids, alkalis, and salts, thereby protecting the inside of the wire harness from chemical damage. PVC has appropriate strength and hardness, which can provide good physical protection and prevent external impacts from damaging the internal shielding layer, protective layer, and wire layer.

[0010] Further, the protective layer is made of aluminum foil.

[0011] In the above solution, the aluminum foil can provide heat insulation protection, has the characteristics of electrical insulation, and good flexibility, thus being able to protect the wire layer, effectively protecting the electrical system, and ensuring the reliability of the wire harness.

[0012] Further, the wire layer includes a plurality of cylindrical conductors.

[0013] In the above solution, the conductors are made of tinned soft copper wire materials. By stranding a plurality of conductors together to form a wire layer, the tinned layer on the surface of the copper wire provides additional protection against oxidation and corrosion of the copper wire, thereby extending the service life of the conductor. The tinned layer also has good welding performance, which is convenient for manufacturing and maintenance. Compared with hard copper wire, soft copper wire has better flexibility and ductility, enabling the wire layer to adapt to various bending and stress conditions and avoiding breakage due to excessive bending.

[0014] An aviation connector plug includes an aviation plug body and also includes the high-protection spring wire harness as described in any one of the above solutions. A wiring port is provided on the aviation plug body, and the connection head is inserted into the wiring port.

[0015] In the above solution, the connection between the spring wire harness and the aviation plug body is achieved by inserting the connection head into the wiring port. This design solution of the aviation connector plug combines a high-protection spring wire harness and a stable aviation plug body to achieve reliable operation in harsh environments, excellent electrical conductivity and connection performance, convenient maintenance and replacement, and wide application adaptability.

[0016] Further, the aviation plug body can be an aviation male plug or an aviation female plug.

[0017] In the above solution, both ends of the spring wire harness can be connected to an aviation male plug or an aviation female plug, or one end can be connected to an aviation male plug and the other end to an aviation female plug. The aviation plug body and the spring wire harness can be freely combined and used, with strong compatibility.

[0018] Further, it also includes a dust cap and a connecting wire. The connecting wire is connected to the dust cap. The dust cap can be covered on the aviation plug body, and the connecting wire can be connected to the spring wire harness.

[0019] In the above solution, covering the dust cap on the aviation plug body can avoid the problems of waterproof and dustproof during transportation on the one hand, and on the other hand, considering the working environment problems, when installing the spring wire harness, there may be a lot of dirt around. At this time, with the protection of the dust cap, it can avoid dirt entering the inside of the aviation plug body and affecting the use, greatly improving the reliability, convenience of construction and the construction efficiency.
