24 pin GT25-24DS-HU R Auto Pin Wire Cable Harness Auto Connector Housing Plug And Terminal 2.0 Series

The three-dimensional layout design of wiring harness is generally considered from these aspects, namely.

It is required that the wiring harness is easy to assemble and the assembly process is goo.

It is required to ensure the maintainability of the wiring harness and the wiring harness has good maintainability.

It is required to ensure the reliability of the wiring harness layout and the reliability of the layout design.

Requires lightweight design of wire harness layout and cost consideration of wire harness layout.

It is required that the wiring harness layout is beautiful, hidden/horizontal and vertical.

1 The wire harness is easy to assemble and has good assembly process.

When designing the wiring harness layout, the first thing to consider is the assembly of the wiring harness. If the wiring harness is finally laid out, but it is found that it cannot be installed, the entire wiring harness layout design plan may have to be overturned and restarted, which will have a very bad impact

Ease of assembly refers to all the parts that need to be installed and fixed on the wire harness assembly, such as the laying of the wire harness assembly itself, the buckles on the wire harness, the installation of brackets, rubber sheaths, connectors and other accessory parts. At the same time, in addition to the requirements for ease of assembly, The wiring harness itself should also consider whether it will affect the installation of peripheral parts.

1) Wire harness segmentation and wire harness assembly installation bundle layout

The segmented design of the wiring harness must meet the premise of ease of assembly, and try not to add too many processes to the final assembly. for example:

Separate assembly can be used for different areas of the vehicle, such as door lines, instrument panel lines, etc.; at the same time, it should be considered that it is best to complete the assembly without using special tools.

Consider modular assembly of large assemblies as much as possible to increase the assembly speed of the production line. For example, the transmission wiring harness and engine wiring harness are assembled to the transmission and engine body respectively, and then assembled to the chassis as a whole.

If the diameter of the wire harness is too large, enough space must be reserved when bending at a certain angle. For trunk branches, the bending radius of the wire harness is generally required to be greater than twice the diameter of the wire harness to prevent the bending space from being too small and affecting the wire harness assembly.

When assembling the wire harness, do not pull the wire harness too tightly (especially when arranging the wire harness laterally) to avoid causing the fixed point position of the wire harness to shift when the vehicle is in a bumpy state, resulting in an instant increase in the distance between the two fixed points, thereby elongating the wire harness and causing The internal contacts of the wiring harness are pulled out/virtually connected, the wire parameters change, and the wires are even pulled off.
