Electronic wire harness processing technology manufacturing matters

Electronic wire harness processing can be used in different fields and different types. Commonly, there are automotive wiring harness processing, electronic wiring harness processing, terminal wiring harness processing and so on. In the electronic wire harness processing should pay attention to the following points: First, electronic wire harness processing appearance check 1. Tension moderate but not too loose or too tight. 2. After rolling the surface of the copper wire without sticking to the phenomenon of gray. 3. Cable laying is good, uniform, no heap edge, underside (high side of the edge or high side of the edge of the edge of the edge), no stranded. 4. Smooth surface, no black lines, messy lines, pockmarks, oxidation, scratches, poor tin plating (sticky tin, tin leakage), diagonal. 5, Hand sewing, handprints. Second, the electronic harness processing wire diameter inspection 1. first micrometer debugging to zero. 2. copper wire to be inspected on the micrometer outside the clamping line, appropriate force (not too heavy or too light) twist the end of the micrometer. 3. hear the micrometer ringing three times, observe the micrometer readings. 4. the same position to repeat the inspection of the same readings two or three times each time the detection of failure to check out to be segmented. 5. inspection of the diameter of the 0.2cm above the different interfaces of copper wire, the wire diameter of 0.2cm, the wire diameter of 0.2cm above the different interfaces, the wire diameter of 0.2cm above the different interfaces, the wire diameter of 0.2cm above the wire diameter of 0.2cm above the wire diameter of 0.2cm. cm above the different interfaces of the copper wire to avoid flat line. Third, the electronic wire harness processing elongation test 1. Open the switch of the elongation instrument. 2. Observe whether the left clamp is in the original position, the instrument shows whether the reading is zero. If the left sensing clamp is not in the original position, the instrument shows the reading is not zero, immediately press the recovery key and set zero key. 3. gently open the wire clamp, the end of the copper wire to be inspected into the sensing clamp, press the sensing clamp, and then gently straighten the copper wire, the other end of the copper wire into the other sensing clamp, press the sensing clamp to clamp the copper wire securely, press the key. 4. when the sensing clamp will pull the copper wire and stop moving, observe its Display readings, as the elongation of the measured copper wire. Fourth, the electronic harness processing resistivity check 1. Open the resistivity meter power switch. 2. Clamp both sides of the inductor clamp, observe whether the reading is zero. 3. If the instrument shows a reading of 0, take a 1m long copper wire to be inspected, with two inductive devices were clamped at both ends of the copper wire. The copper wire to be tested shall not be in contact with any metal object and press the key.4. Check the displayed reading and take the reading to calculate the resistivity.
