一、線束線路故障的原因分析
 
插接件接觸不良,線纜之間發生短路、斷路、搭鐵等。原因主要有以下幾方面。
 
1、自然因素。線束經過長時間在特殊環境的使用、催化,導緻線纜老化、絕緣層破損和機械強度下降,從而産生電氣線纜短路、斷路和搭鐵等故障,引起線纜或者電器件燒損。另外,經過長時間使用的端子發生氧化變形,引起接觸故障,也能使電器件無法正常工作。
 
2、電器件故障。電器件由于長時間使用或者其他原因導緻故障,可能引發汽車線束的短路或搭鐵等故障。
 
3、人為因素。在進行線束安裝或者檢修時,由人為因素導緻線束線纜絕緣層的破損,或者線束安裝的位置錯誤,或者沒有嚴格按照安裝圖進行接線,都可能導緻汽車線束的損壞。另外,在對汽車線束故障進行檢修時,沒有按照線路圖恢複,或者造成亂接、亂剪、糊弄的問題,都容易導緻電器件和汽車線束發生故障。
 
I. Cause Analysis of Wire Harness Line Faults
 
Poor contact between connectors and cables, short circuit, break circuit, tie-up and so on. The main reasons are as follows.
 
1. Natural factors. After a long period of use and catalysis in special environment, the harness leads to cable aging, insulation layer damage and mechanical strength decline, resulting in short-circuit, circuit breakage and iron-tapping of electrical cables, causing cable or electrical components to burn. In addition, after long-term use of terminal oxidation deformation, resulting in contact failure, can also make electrical appliances can not work properly.
 
2. Electrical failure. Electrical appliances may cause faults such as short circuit of automobile wiring harness or tie-up due to long-term use or other reasons.
 
3. Human factors. When installing or repairing the harness, the damage of the insulation layer of the harness cable caused by human factors, or the incorrect location of the installation of the harness, or the failure to connect strictly according to the installation drawing, may lead to the damage of the automobile harness. In addition, failing to restore the wiring harness according to the circuit diagram or causing problems of random connection, random cutting and confusion in the repair of the wiring harness faults of automobiles can easily lead to faults of electrical appliances and wiring harnesses of automobiles.
