A harness is a collection of wires and cables used to transmit information or operational signals. The binding materials of the wire harness are clamps, cable belts, sleeves, electrical tape or a combination of such materials.

What's a harness?

1. Assembly Process

The wire beam sub-material number must be compared with the positioning plate to determine the size of the cutting line. In the process of wiring harness assembly, it is often possible to meet the size of sub-material, but it can not meet the size of positioning plate, resulting in a lot of unnecessary waste. Sub-material number is also under electrical testing and full inspection.

2. Wiring of a Harness.

1). It will be in accordance with the requirements of the surface of the sub-material number tiled on the positioning board.

2). In the wiring, first to a region of a region to put, a single region of the sub-material number after put, then put the sub-material number across the region.

3). Cross-regional sub-material number should be put simply at first, and then complex.

3. PIN Insertion (a TER with part of the PIN not inserted must first be inserted into the corresponding connector).

Binding line (binding line location according to the positioning board, the starting point of the binding line is generally in the positioning board at the starting point of the two lines) .

Wiring Harness Assembly Process and Requirements

4. Electrical Testing. Because the line position of the assembly line is complex, the test data must be checked strictly. 2 after PE & QE are confirmed, the test can be carried out.

5. Full Inspection.

1). Check that terminals and Conn are within the tolerance zone.

2). Check whether the binding ring is even. Check whether the assembly method of the parts is correct.

6. The material number of the wire beam is put into storage. The sub-material number must PASS the OQC test before the follow-up action.

Wiring Harness Assembly Process and Requirements

Assembly Process Requirement

1. After wiring harness assembly, all wiring harness to parallel, and can not move. However, a cord or harness should not jam the wire.

2. PIN insertion or welding, the core wire can not be wound together, but also can not be too tight.

3. When wiring, the terminals, HOUSING, D-SUB, IDC, Conn of each sub-material number must match the mark of the locating board.

4. Each sub-material number wire must be arranged according to the route on the positioning board.

5. When tying, the rope should move vertically from the bottom of the loop.

6. The harness must be tightened and the tail must not exceed 1 mm.

7. The distance between the two loops is about 25mm, and the tail should be kept about 10mm at the end of each rope.

8. Each rope should be tied in a knot at the beginning and end.

9. When tying the string, do not loop or twist the rope. Coupler can not be stuck on the positioning nail, pull the rope, should be fixed on the line head of the rope on the positioning nail, and then bind the line. Otherwise, it is easy to cause the terminal to pull off the core wire or the terminal to fall off.

Assembly Quality Standard

Wiring harness assembly finished product, to test the wiring wiring conductivity, the requirements to achieve the conductivity of 100% , no short-circuit, short-circuit, wrong-circuit phenomenon. At the same time they also have wiring harness customer requirements of quality standards, packaging to provide safety and quality assurance.

Every step of wiring harness assembly and inspection should be done meticulously for perfection, and standardize operation requirements are accordance with ISO 9001:2015 quality management system.
