Points to note when processing technology for electronic custom wire harnesses

What points should be paid attention to in the processing of electronic customized wiring harness? In the processing of electronic wiring harness, there are problems such as broken wire core, terminal wire terminal falling off easily, false welding of electronic wiring harness and wiring harness connector not being threaded in place. Some of these problems are caused by human misoperation, some are caused by wiring harness processing equipment, and some are caused by wiring harness raw materials. These problems will affect the quality of wiring harness. The terminal wire of the 1、 falls off, which is just the opposite of the situation of the third party above. The terminal machine is too loose when adjusting the machine, resulting in the terminal can not firmly wrap the harness; The harness connector of the 2、 is not inserted in place, which mainly occurs during the assembly of the harness. The harness of the electric vehicle is not inserted in place when it is inserted into the rubber shell of the connector. Under normal circumstances, there will be a "click" sound when it is inserted in place. In order to ensure that it is in place, it is necessary to pull back, that is, hold the connector with one hand and pull the wire with the other hand. Be careful not to use too much force to avoid breaking the harness; The electronic wiring harness of the 3、 has poor soldering, when the wire core is not tinned enough or the contact surface of the two wire cores is too small during the welding processing of the wiring harness, the poor soldering phenomenon will occur, because the welding position is required to be covered with an insulating sleeve, the appearance is invisible, some problems can be found in the quality inspection process, and the wiring harness is easy to fail if installed on the equipment; There are three reasons for the breakage of the wire core of the 4、 electronic wire harness: First, the quality of the wire harness raw material cable is not up to standard, the flexibility is not enough, or the wire diameter is not enough; Second, when the wire harness is cut, the wire feeding roller presses the wire too tightly, causing the wire core to be broken; Third, when the wire harness is crimped to the terminal, the machine is adjusted too tightly, and the pressure under the blade is too large, causing the core wire to be broken.
