(Summary description)The selection of harness materials for UAV is closely related to the quality and service life of harness. Don't be greedy and cheap when choosing harness products for drones. If you are a UAV pilot or maintenance personnel, you must have enough technical ability to distinguish between qualified and unqualified UAV harnesses, otherwise it will lead to unnecessary losses. Cheap products may be made of inferior materials.

The selection of harness materials for UAV is closely related to the quality and service life of harness. Don't be greedy and cheap when choosing harness products for drones. If you are a UAV pilot or maintenance personnel, you must have enough technical ability to distinguish between qualified and unqualified UAV harnesses, otherwise it will lead to unnecessary losses. Cheap products may be made of inferior materials.


Usually, the harness of UAV consists of wires, insulation sheath, terminals and wrapping materials. In practical work, because different types of equipment need to use different kinds of wire harnesses, their quality requirements are also different. We only need to know these data, so it is convenient to distinguish the advantages and disadvantages of UAV wiring harness.

 

1. In order to avoid short circuit or open circuit during wiring, copper alloy or aluminum alloy can be selected. The copper (copper) used in the terminal is mainly brass and bronze (the hardness of brass is slightly lower than that of bronze), which occupies a considerable proportion in these brasses. In addition, different coatings can be selected according to different needs.

2. These materials of UAV wiring harness have good flame retardancy and mechanical properties, but their heat resistance is poor, which can't meet the use requirements. Therefore, it is necessary to consider selecting materials with high heat resistance and good mechanical properties to make insulating sheaths. The sheath (plastic part) is usually made of PA6. PA66。 ABS, PBT, pp and other materials. According to the actual situation, flame retardant or reinforcing materials can be added to plastics to achieve the purpose of strengthening or flame retardant, such as glass fiber reinforcement.

3. Selection of wiring harness: According to different use environments, select the corresponding wires.

4. UAV wiring harness can play the functions of wear resistance, flame retardant, anti-corrosion, anti-interference, noise reduction and beautification. Adhesive tape or non-woven fabric is often used to dress patients' wounds. Packaging materials are usually selected according to the working environment and space size. As far as dressing materials are concerned, adhesive tape, corrugated pipe and PVC pipe are generally used.

 

The harness of UAV can be divided into full utilization type, partial utilization type and link type according to different structures, and can be divided into loss type and waiting type according to different service modes (see random service system). According to the different connection relations, it can be divided into direct connection harness and indirect connection harness. According to the number of service load sources, it can be divided into infinite load source harness and limited load source harness.

 

Based on the load source call behavior, that is, whether the user will make a new call attempt when the call fails, the UAV harness can be divided into two types: repeated call system and non-repeated call system. In a non-repetitive call system, because each client is connected to the network through one or more ports, when a call occurs, the connection will be interrupted. There are repeated calls in all practical communication systems, and there are similarities between non-repeated call systems and repeated call systems.
