For the whole vehicle wiring harness design, the matching of parts and components is an important part. The general layout should consider the alternatives of various parts and the feasibility analysis of various solutions, and conduct close exchanges and cooperation with parts and components manufacturers. Finally, the matching of body molds, accessories and chassis parts is realized, which lays the foundation for further improvement of the digital model. Automobile wiring harness processing is used in different fields, and it is also divided into different types. The common ones are automobile wiring harness processing, and vehicle wiring harness processing, automobile wiring harness processing, etc.


There are a few things that need to be paid attention to in the processing of automobile wiring harness:


1. Appearance inspection 1) The tension is moderate but not too loose or too tight; 2) There is no sticky ash phenomenon on the surface of the copper wire after rolling; 3) The wiring is good, uniform, without stacking edges and under-edges (the side is high and the side is low or the two sides are high and the two sides are low. ), no strands; 4) smooth surface, no black lines, no random lines, no pitting, no oxidation, no scratches, no scratches, no bad tin plating (tin sticking, tin leakage), no skew Line, no hand connector, no handprint;


 2. Wire diameter inspection 1) First adjust the micrometer to zero; 2) Put the copper wire to be inspected outside the clamping line of the micrometer, and twist the end of the micrometer with appropriate force (the force should not be too heavy or too light); 3) When you hear After the micrometer beeps three times, the reading can be observed; the readings should be repeated two or three times so that the same position cannot be detected each time, and the test should be segmented; the copper wire with a wire diameter of more than 0.2cm should check the different interfaces of the copper wire , so as not to have flat wires;


3. Elongation test 1) Turn on the switch of the elongation tester; observe whether the clip on the left is in the original position, and whether the reading displayed by the instrument returns to zero. If the left sensing clip is not in the original position, the reading displayed by the instrument is not correct. To reset to zero, press the reset button and the zero button immediately; 3) Gently open the clamp, put one end of the copper wire to be tested into the induction clamp, press the induction clamp, and then gently straighten the copper wire and put it in the induction clamp. Put the other end into another induction clip, press the induction clip to clamp the copper wire firmly, and press the test button; 4) After the induction clip breaks the copper wire and stops moving, observe the reading displayed on it is the detected value Elongation of copper wire;


4. Vehicle wiring harness resistivity inspection 1) Turn on the power switch of the resistivity tester; 2) Clamp the induction clips on both sides to observe whether the reading is zero; if the reading displayed by the instrument is 0, put the Take a 1m long section of the copper wire and clamp both ends of the copper wire with two induction clips. The detected copper wire should not be in contact with the metal object A. Press the test key; 4) Observe the displayed reading, and take the reading to measure the resistance rate is calculated.
