Advantages and disadvantages of modular design for wiring harness

Modular design is based on functional analysis of a range of different functions or products with the same function, different performance, and different specifications. It divides and designs a series of function modules, and forms different customized products through the selection and combination of modules. To meet the different needs of the market. In the future design process of wire harnesses, modular design is a trend, especially the market demand is increasingly diversified, and modularized wire harness products are emerging to meet the different needs of the wire harness market. Below, Hooha engineer briefly explains the advantages and disadvantages of the modular harness.

Modular design of the wire harness has many advantages, such as: harness design drawing is simple, easy to read and draw; a wire harness wire color is not easy to repeat, the same wire harness can be used in different ways to protect; suitable for mass production; saving assembly man-hours; The damage to a certain section of line is easy to replace and maintenance is also convenient. However, the modular design of wire bundles also has many shortcomings, such as: the use of modular design of the wiring harness to increase the interconnection between the wires, the resistance must be minimized on the connection terminal, pull-out force between the connectors should be large enough, but also consider the power distribution of the vehicle. In order to solve these shortcomings, the Hongqi sedan uses a T-type bracket to fix the butt-jacket between the wire harnesses. Use the central distribution box to rationally distribute different types of power and signals to the various wiring harnesses through connectors. Modularization is a new design idea developed on the basis of traditional design. It is a method of assembling components into a large assembly for final assembly and is now widely used. It is expected that the modular design of the harness will become more popular in the future.
