Common protection of automotive wiring harness

Automotive wiring harness protection generally use bellows, PVC pipe, PET winding pipe, woven cloth, sponge, electrical tape for protection, and will use the cable ties, straps for fixed. Mainly on the car cable to play a fixed, wear-resistant, fire-retardant, insulation, anti-corrosion, anti-interference, reduce noise and beautify the appearance of the role.
Protection mode one: bellows

Although the shape of the bellows are very similar appearance, but there are many kinds of material. Polypropylene (PP), nylon (PA), polypropylene modified (PPMOD), its main feature is good wear resistance, high temperature resistance, even the most common bellows high temperature can reach 100 ℃, and Flame resistance is better, the bellows itself has a good flexibility, good bending resistance. Bellows are the most common in cabin and front and rear protection structures.
Protection mode two: PVC pipe, heat shrink tube

PVC pipe for the soft PVC material, its function and similar to the bellows, the main features or soft, good anti-bending performance. But the wear resistance in general, temperature resistance can generally be 80 ℃ ~ 105 ℃. PVC pipe is mainly used for four doors and cab, and more for the line where the beam.
Protection of three: industrial plastic cloth
Industrial plastic sheet material for the PVC, the appearance of a black mesh protection film, crimped after the dressing in the wiring harness, the main feature is good soft, easy to bend. Where the backbone harness needs to be bent, or where the thicker cable branches are visible, the wear resistance of the industrial plastic sheet is poor and is rarely seen.
Protection mode four: sponge

Sponge is also known as sponge tape, its function and use similar to the tape, the main feature is the noise reduction performance, and more for the door and the cab needs to reduce the noise reduction of the place, to eliminate the abnormal beam.
Protection mode five: wiring harness wrapped tape
Tape is the most basic, the most commonly used protective materials, the whole wiring harness need to rely on tape for fixed molding. Tape with good corrosion resistance, oil resistance and insulation characteristics. According to the different level of harness protection, tape wrapping method is divided into all wrapped, Tape classification is also a lot, generally divided into PVC tape, high temperature PVC tape, cloth tape, velvet tape and so on. PVC focus on wear and flame retardant, the material noise performance is poor, cheap. Burkina Faso tape high temperature, high wear resistance. Velvet tape noise reduction performance, can eliminate abnormal sound.

Protection of six: rubber sheath
Rubber sheath, also known as rubber parts, through-hole rubber parts, door rubber parts, commonly used in automotive wiring harness through the warehouse and the door of the sheet metal parts to protect the wiring harness
Protection of seven: bracket guard
The harness bracket is less versatile and the brackets are designed to be different in different models. The brackets are equipped with high cost of R & D and need to design molds. Most manufacturers will not control the overall cost of the vehicles. Widely used this protection.
