Electronic Wiring harness – Material design

Line maintenance is to be maintained on the wire, overall maintenance of the circuit electrical equipment. The main maintenance equipment includes fuses, circuit breakers and fusible wires. High lattice electrons.

1. Selection criteria for fuses

Engine ECU, ABS, etc. have great influence on the performance and safety of the whole vehicle. For other electrical equipment which is easily disturbed by other electrical equipment, it is necessary to set fuses alone. Engine sensors, all kinds of alarm lights and external lights, horns and other electrical equipment on the vehicle performance and safety is also a great influence, but this kind of electrical load is not sensitive to each other’s disturbance. Thus, these electrical loads can be combined with each other according to conditions, using a fuse together.

The electrical loads of the usual electrical equipment set up for added comfort can be combined with one another according to the condition, using a fuse together.

Fuse is divided into fast melting type and slow melting type. The primary component of quick-melt fuse is thin tin line, during which the layout of the chip fuse is simple, reliable and good vibration resistance, easy to detect, so it is widely used; Slow melt fuses are actually tin alloy sheets. Fuses in this layout are usually connected in series to rational load circuits, such as motor circuits.

Resistive load and inductive load should avoid using the same fuse. Usually according to the maximum continuous operating current of electrical equipment accounting and determine fuse capacity, can be experienced by the formula: fuse additional capacity = circuit maximum operating current ÷80% (or 70%).

2. The circuit breaker

The biggest characteristic of circuit breaker is recoverability, but its cost is higher, less use. A circuit breaker is usually a thermal sensitive mechanical device that uses different thermal deformation of two metals to open and close the contact or connect it by itself. The new type of circuit breaker, using PTC solid data as the overcurrent maintenance element, is a positive temperature coefficient resistance, according to the current or temperature bump open or close. The biggest advantage of this maintenance component is that when the fault is removed, it can be connected on its own initiative without manual conditioning and disassembling.
