1、 Wire (low voltage wire, 60-600v)
Type of wire:
National standard line: QVR, QFR, QVVR, qbv, qbvv, etc
Day marking line: AV, AVS, AVSS automobile harness, AEX, AVX, cavus, EB, TW, she-g, etc
German standard line: flry-a, flry-b, etc
American standard line: Sxl, etc
Common specifications include wires with nominal cross-sectional areas
of 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0, 6.0, etc
2、 Sheath
The sheath (rubber shell) is usually made of plastic. The wires of pressed terminals are
inserted into it to ensure the reliability of connection. The materials mainly include PA6, PA66
ABS, PBT, PP, etc
3、 Terminal
A shaped hardware component, crimped on a wire to connect different wires to transmit signals,
including a male terminal, a female terminal, a ring terminal andRound terminals, etc. The materials
are mainly brass and bronze (the hardness of brass is slightly lower than that of bronze), of which
brass accounts for a large proportion.
4、 Sheath accessories: Waterproof bolt, blind plug, sealing ring, lock piece, buckle, etc
It is generally used to form connectors with sheathed terminals
5、 Harness via rubber parts
It is wear-resistant, waterproof and sealed. It is mainly distributed at the interface between the engine
and the cab, and at the interface between the front compartment and the cab (2 places on the left and
right in total)The interface between the four doors (or the back door) and the carriage and the inlet of
the fuel tank.
6、 Tie (clip)
An original, usually made of plastic, used to fix a wire harness in an automobile. There are cable ties and
bellows lock cable ties.
7、 Pipe
It is divided into corrugated pipe, PVC heat shrinkable pipe and glass fiber pipe. Braided pipe, wound pipe,
etc. Used to protect the harness. (classified by diameter)
1. Bellows
The corrugated pipe generally accounts for about 60% or even more in the bundle binding. The main
characteristics are good wear resistance, high temperature resistance in high temperature area
Flame retardant and heat resistance are very good. The temperature resistance of the bellows is
between - 40-150 ℃. Its materials are generally divided into PP and PA. PA material in flame retardant
It is superior to PP in wear resistance; But PP material is better than PA material in bending fatigue
resistance.
2. PVC heat shrinkable pipe
The function of PVC pipe is similar to that of corrugated pipe. PVC pipe has good flexibility and bending
deformation resistance, and PVC pipe is generally closed, so PVC pipe
It is mainly used at the branch of the harness bend to make the wire smooth transition. The heat-resistant
temperature of PVC pipe is not high, generally below 80 ℃.
8、 Adhesive tape
Production tape: wrapped on the harness surface. (divided into PVC, sponge tape, cloth tape, paper tape, etc.)
. Quality identification tape: used for identificationDefects in production products.
The tape plays the roles of binding, abrasion resistance, insulation, flame retardant, noise reduction and
marking in the wire bundle, and generally accounts for about 30% of the binding materials. Wire harness
There are three kinds of tape: PVC tape, air flannel tape and cloth base tape. PVC tape has good abrasion
resistance and flame retardancy; Temperature resistance is around 80 ℃, noise reduction
Not good, the price is cheaper. Flannel tape and cloth base tape are made of pet. The flannel tape has
the best binding property and noise reduction property, and the temperature resistance is about 105 ℃;
The cloth base tape has the best wear resistance and the highest temperature resistance is about 150 ℃.
Flannel tape and cloth base tape have the common disadvantages of poor flame retardancy and high price.
