How the wiring harness works in an electromechanical system environment

It is important to seal the electrical contacts of the harness when applied to the exterior of the car and under the hood. For connector manufacturers, providing a low-cost, high-stability, easy-to-assemble submersible connector solution is a challenging task. In high-density or multi-pin systems, it is standard practice to use gasket seals or porous kiln seals. There are two major issues that must be addressed when designing such seals.

Improve mechanical strength. Selecting suitable irradiation conditions, such as controlling a certain irradiation dose, to ensure that the material does not degrade, the mechanical properties such as tensile strength and wear resistance of the material can be improved after irradiation crosslinking. The tensile strength is more than doubled, so that the insulating material layer can be thinned or the insulating layer can be eliminated, which is desirable for ships and aircraft. This technology brings significant process cost benefits by pressing a solderless pin into the hole in the metal plate. Designed for demanding automotive applications, the press-fit terminals are specifically designed to provide fully controllable force during insertion, minimizing drag and deformation and ensuring a secure interface.

The overall functional model of the system is the information flow model between the main functional modules of the system, including five functional modules, corresponding to the five phases of the harness assembly planning in the virtual environment. The human-computer interaction layer is responsible for handling human-computer interaction transactions in a virtual assembly environment, such as tasks related to the mouse, keyboard, voice input and output devices, data gloves, etc., to realize information exchange between the designer and the system, mainly including human-computer interaction device data. Reading, assembly operation instructions and parameter input during assembly process planning, roaming of virtual scenes, etc. The function of the input information parser is to parse the input information of the designer and distribute it to the corresponding function module for burying.

There is a special type of wire harness in electromechanical products. These wire harnesses are in motion during the operation of the product. The moving wire harness is usually fixed at one end, and the other end is moved by the moving parts according to a certain law. By controlling another set of multi-select switches, the harness can be connected to the ground one by one. During the test, we exchanged the voltage at the connection between the switch and the power supply into a digital signal, and then sent the data to the MCU for processing.

There are two types of closed busbars. One type of closed busbar has a large current carrying capacity, but it is not resistant to high temperature. It is usually installed on the line that transports the mains. This kind of busbar is also called dense closed busbar. Therefore, it is designed in the fire line and emergency power line. When the busbar is used, the fire-resistant closed busbar is used.

In order to meet the requirements of the operability of the harness model in the virtual environment, the harness and pipeline modeling technology based on discrete control points is adopted, and the smoothing degree of the harness model is improved by the curve-based smoothing algorithm. The algorithm completes the arc transition of the pipeline model.
