Wire Harness and Cable Assembly
What Is a Wire and a Cable
A wire is a single strand of conductive material such as copper, aluminum, or tin.
A cable, on the other hand, consists of two or more wires bundled together, often braided or bonded.
What Is a Wire Harness and Cable Assembly
✅ Wire Harness
-
A simple outer sheath that holds together wires or cables.
-
Usually made from thermoplastic or thermoset material to provide basic protection.
-
Ideal for organizing internal wiring in controlled environments.
-
Limitations: Not designed to withstand extreme temperature, friction, or moisture.
✅ Cable Assembly
-
A more rugged, protective casing that encloses wires or cables.
-
Typically made from heavy-duty materials like vinyl or thermoplastic rubber.
-
Designed for harsh environments: heat, moisture, abrasion, vibration, etc.
Key Differences Between Wire Harness and Cable Assembly
Application Environments
| Feature | Wire Harness | Cable Assembly |
|---|---|---|
| Usage | Internal use (PCs, electronics) | Industrial or outdoor applications |
| Conditions | Stable, dry, enclosed | Harsh: dust, oil, temperature swings |
| Space Constraints | Flexible, compact design | Custom sizes and robust builds |
Structure & 材料
| Feature | Wire Harness | Cable Assembly |
|---|---|---|
| Sheath | Light plastic or rubber wrap | Heavy-duty thermoplastic or vinyl |
| 层数 | Thin external sheath over pre-insulated wires | Fully enclosed, high-strength structure |
| Cost | Low-cost solution | Higher cost, more robust |
Durability
-
Wire Harness: Limited durability; suitable for low-risk environments.
-
Cable Assembly: High durability; resists heat, pressure, moisture, and mechanical stress.
PCB Wire Harness Applications
🟢 PCB Wire Harness
-
Connects printer heads to the mainboard.
-
Also used in scanners, copiers, plotters, audio systems, IoT devices, etc.
-
Ensures stable signal transmission in modern electronics.
🔵 PCB Data Wire Harness
-
Built with pure copper core and quality plastic insulation.
-
Designed to transmit data signals within electronic and electrical devices.
🔴 PCB Power Wire Harness
-
Equipped with precision copper terminals and flame-retardant sheaths.
-
Connects AC power to PCBs via:
-
U-shape / O-shape terminals
-
Fast-plug connectors
-
-
One end is soldered to the PCB; the other may have a terminal.
