Automobile line manufacturer analyzes the case of car wire harness burning

Car wire burn accidents are rare, but the severity of the consequences is alarming. Auto wire manufacturers said many of the incidents were caused by faulty wiring. The following three cases of wire bundle burning accidents are introduced and the causes are summarized for sharing.

   A tianjin Charley is in use. The ac generator wire bundle was found to be burnt out. Upon examination, it was found that it was caused by short connection of the circuit and severe heat of the wire. Fortunately, timely detection and measures were taken to prevent major fire accidents. In this regard, wan lianhe tai summed up the reasons why the wire harness was burnt out in years of automobile wire harness processing as follows:

A. Car line manufacturer says the two - column of ammeter often USES plastic insulator sleeve, plastic heat dissipation sex is poor, want to bear strong current already. Also to withstand turbulence and vibration, if the meter connection is loose or contact is not good, there will be temperature rise. Easy to lead to plastic melting and iron, resulting in power cord burn.

B. The power wire harness is usually fixed by thin sheet iron card. Its edge is as sharp as knife edge, and the surface of the sheet metal card is not insulated. When the vehicle vibrates and bumps in the long run, the power cable bundle will inevitably be worn out, cut and cast iron, causing the wire bundle to burn down.

C. When the electric equipment is temporarily connected, the current inlet and outlet of the fuse are not clear, that is, the power cord is drawn at will. Or after the fuse is burnt out, the fuse of the same specification is not replaced as required; Or use thick copper wire instead of fuse, lose protection and burn wire bundle.

D. The connection of the connecting post is not secure, resulting in a large pressure drop and heating, a long time, the insulation gasket will be damaged and the lapping iron short circuit. The connection post after ammeter and other instruments must be connected reliably. In addition, the wire connecting screw fixed on the frame terminal board should not be too long. To avoid burning wire bundles with iron.
