With the growing demand for electronic and electrical safety, comfort and economy, electric appliances, electronic appliances function is also more and more, so the connection of various electrical wiring harness is also more and more complicated, become the contemporary electronic failure of multiple links, but also because of this in the electronic and electrical equipment design and manufacture people pay more and more attention. Below is a brief introduce the electric wire harness design process
1 Schematic Design and calculation
1.1 according to the "electrical schematic diagram is drawn electrical configuration and technical requirements for electrical design task book"
1.2 according to the electric power determining insurance capacity and line size, and load distribution on each electrical system, determine the total insurance capacity
1.3 calculation of wire diameter: according to the formula (see photo)
Type: I -- P -- A; current, electrical power, W; U -- voltage, V;
A -- wire diameter, mm2; P -- Copper resistivity (approximately 0.0185 mm2/m); L = m; the length of the wire, Ud -- allowing maximum voltage drop
At the same time, also want to consider the following:
A. wire is too long may be appropriate to the wire diameter enlargement;
B. wire with multiple connector adapter connected to the appliance situation, consider the terminal voltage drop is obvious, may be appropriate to the wire diameter enlargement
1.4 different forms of wire with the allowable current and line voltage is different
