The core component of the module signal line
Wire
Material: mostly copper (good conductivity), silver-plated copper is used in some high-precision scenarios (reduce signal loss).
Structure: single-strand or multi-strand twisted wire (multi-strand wire has better flexibility and is suitable for frequent bending environments).
Insulation layer: PVC, XLPE (cross-linked polyethylene) or fluoroplastics are used, and insulation layers with different weather resistance are selected according to the use environment (such as high temperature, oil pollution, corrosion).
Connector
Function: to achieve rapid docking and separation of the
Wiring Harness and the module, which is convenient for installation, maintenance and replacement.
Type: According to the interface form, it can be divided into plugs and sockets; according to the connection method, there are snap-on type, threaded type, welding type, etc.; according to the number of pins, it ranges from a few pins to hundreds of pins (such as automotive ECU connectors are mostly dozens of pins).
Material: The shell is mostly plastic (such as PA66, which is resistant to high temperature and high strength), and the contact terminal is copper alloy (such as brass, phosphor bronze, to ensure conductivity and elasticity).
Protection and fixing parts
Protective sleeves: such as corrugated tubes (wear-resistant and impact-resistant), braided mesh (anti-electromagnetic interference), heat shrink tubes (insulation and sealing), etc., select the protection level according to the usage scenario (such as the engine compartment of a car, inside industrial equipment).
Fixing parts: including cable ties, wire clips, brackets, etc., used to fix the wiring harness inside the equipment to avoid wear or poor contact caused by shaking.
