Technical Requirements for Electronic Wire Harness Processing

First, measure the length of the entire vehicle wiring harness: the length of the trunk road; the length of the main line; the length of the branch point; maintenance of waterproof casing and sheath spacing (i.e., the length of the exposed power plug), second, the socket and robustness test: cable line is not damaged selection; no special requirements for sockets, terminals should be individually clamped in the electrical conductor and cable sheath, electrical conductors can not be pressed off, cable sheath can not be pressed into the Electrical conductor socket position, in Figure 1 shows the a area whereby the cable line can be seen in the electrical conductor, but can not prevent plugging; cable sheath socket position by not less than three cycles of the system bending test, the b area is still visible in the cable sheath; terminals and cable connection should be solid, in the requirements of the tensile force can not be damaged and loosened, and its value of the tensile force should not be less than the requirements of the standard value. Third, the point of contact provisions: selection of non-welding material welding process welding welding welding surface layer does not allow air oxidation, broken wire, broken and cable sheath melting condition; selection of non-welding material welding process tearing force should not be less than the required standard value. Fourth, the sealing plug in the crimping can not be damaged. Cable line and sealing plug in the middle, sealing plugs and cable sheaths do not need to look at the middle of the gap thus visible. Cable and sealing plug and terminal socket, in the a area to be seen from the sealing plug and cable cable cable sheath top. Fifth, the entire vehicle harness bundling, should be inseparable, proportionate, not loose. Selection of maintenance waterproof sleeve, no offset and jeopardize the cable harness bending condition. Sixth, the vehicle harness cable and terminal insulation tube should be inseparable set in the joint position, no offset, no loose condition. Seven, the vehicle wiring harness in the cable and parts should be properly installed, do not need to have shifted conditions, terminals in the wire sheath can not slip off. Eight, the entire vehicle wiring harness route conductivity, no short-circuit failure, wrong way condition. Nine, labeling: the entire vehicle harness should be accompanied by a significant labeling is not easy to fall off; the entire vehicle harness labeling the necessary content is as follows: the name of the entire vehicle harness, the available car line, equipped with; manufacturers, time and other manufacturing information content.
