The survival of the fittest in the market economy, the quality of the continued momentum of enterprise development, excellent quality, any fancy packaging are not last long. Therefore, the wiring harness manufacturers should perform strictly regulate the production technology and complete quality testing system, and do everything possible to ensure that the wiring harness quality.

1, wiring harness wires and terminals in the junction of the insulating sleeve should be tight sets in the joints, no torn off and the displacement phenomenon; 

2, the wiring harness wires and parts should be fitted correctly, there should be no dislocation, the terminal should be in place in the jacket should not prolapse; 

3, the connectors shall comply with the provisions of the Q / FT A095 or the Company allows the specifications of the products; 

4, complete logo: including security identifies the sub-square test for mark, the number and its implementation of the wiring harness standard number, certification mark; 

5, no special requirements, tape protection layer application of thin PVC tape folding tight package, the swallow received less than 4 mm, the surface shall not have the thick joints and gaps; 

6, the loose yarn protective layer surface should be uniform; 

7, the plastic casing, the bellows are application of adhesive tape fixed bandage on the wiring harness; 

8, the contact surface insulation should be a good conductor should not pressure off; 

9, should be protective treatment of the surface of the metal clamp that does not allow any burrs, rust, scars and other defects; 

10, terminals and wire connections should be used to crimp the terminals should be pressed on the conductor and the insulation, the conductor should not pressure off; 

11, the harness should be used insulation bandage, the bandage should be close, even, do not loose; use of protective casing should be no shift and the impact of wire bending phenomenon.

Line guide wire bundles pass rate of 100%, no short-circuit the wrong way phenomenon, and have the customer demand for quality, safety and certification.
