Development of junctions module for the car wiring system

摘要

The recent trend surrounding the car industry is changing to emphasize environmental protection and toward value added multiplexed functional performances. Under these circumstances, wiring systems tend to be larger and more complex with the increase of car electronics. Carmakers domestic and abroad are deploying competition for survival in an attempt to reduce substantial cost reduction. One of the measures to reduce costs is implementation of modules in car assembling. Modularization is considered in a wide range from small parts such as switches, to parts of the car body such as bumpers. The biggest theme in the implementation of module is considered as the connection reliability and workability of each module products. We have paid much effort in developing a new wiring system for cockpit modules and as a result, we have succeeded in developing a special junction module implement cockpit modules. Junction module is designed to achieve automatic connection of the wiring of the cockpit and body by applying the newly developed float-mount connector and a system that consists of a junction block which is the essential part of wiring function and ECU (Electric Control Unit) of the car IAN. At the same time, by applying the newly developed wall-mount connector, we have succeeded in relinquishing hole wiring which is considered as one of the biggest problems at the time of dismantling wire harnesses. We will introduce a new wiring system where the new junction module is applied.
