Assembly requirements for toy wiring harness: wiring harness assembly and sealing operation guidance. All wiring harnesses require neat wiring, firm fixation, no swaying or hanging, no interference, no frictional damage. In order to make the wiring harness layout reasonable and beautiful, various types and sizes of fixing brackets can be used when wiring. When laying the wiring harness, fully consider the specific installation positions of various electrical components and plug connectors. At the same time, it must be combined with the structure of the toy body for wiring and reserve the length of the wiring harness.

Since many cables work outside of electronic chassis and cabinets, and are not fixedly installed, they are susceptible to various mechanical damages and damage electrical connections. Therefore, cable assembly has its own special requirements. The processing technology of wire binding and the electrical connection of electronic equipment mainly rely on wires of various specifications to achieve. In some more complex electronic devices, the connected wires are many and complicated. If they are not arranged in any way, they will appear very messy, that is, they are not beautiful and not easy to maintain. In order to simplify the assembly structure, reduce the occupied space, and facilitate inspection, testing and maintenance. Often when the product is assembled, the wires of the same direction are bundled into a certain shape of wire ties (also called wire handles, wire harnesses). In this way, wiring and product assembly can be separated, which is convenient for professional production, reduces errors, and improves the installation quality of the whole machine assembly. When arranging electrical wiring harnesses, consider as much as possible the modular assembly of large assemblies to increase the assembly speed of the production line.
