Development of Small Connector for Electrical Components

摘要

In recent automobile systems: (1) Securing the space to mount and install more electrical components in vehicles has become a big issue. Thus, the downsizing of components is more required than ever. (2) Electrical components are mounted (inside and outside the cabin) in severe environments where they are exposed to disturbances such as heat and vibrations. Conventional on-board connectors are highly reliable, but they are large and it is difficult to secure the needed mounting space. Therefore, the users require: (1) The further downsizing of connectors (2) Smaller connectors that can endure severe environments To satisfy these requirements, Sumitomo Electric Industries, Ltd. and Sumitomo Wiring Systems, Ltd. have successfully reduced the length of the section where a terminal is crimped on the wire, and developed a small, highly-reliable connector for wiring components. A unit maker is interested in this connector for an application in a small wiring space, as shown in Fig. 2. In addition, this connector will be used to connect the wiring harness and the electric power-steering rotation angle sensor in the Toyota Estima (to be sold from January 2006).
