The Screw Terminal Blocks Manufacturers from wave soldering to reflow soldering means that connector materials need to be able to withstand significantly higher temperatures, so the heat distortion temperature (HDT) of the material needs to be higher than 250°C. F11 is one of the halogen-free high temperature resistant plastics that has obtained VDE certification. A new connector material solution turned out to break this deadlock. It penetrates into the lives of millions of households and affects the average home appliance ownership of the society. The Rast standard version is a series of specific connection coefficients for Peugeot, including the geometric diameter of the housing (upper component [connector] and lower component [welding tank], as well as the specifications of the upper and lower components according to coding or positioning. . The transition of connectors in Asia and the United States to Rast has slowed down, mainly due to its existing equipment Most of the foundation is crimped terminal equipment, and the initial investment of the Rast IDC system is relatively high. The key to this trend is standardization and modularization. At first, standard crimp-snap connectors were crimped into the line guide with an open wire tube structure, and then snapped Into the shell, this structure reveals some Rast characteristics. The development melody of sensor technology will not change, and it still occupies an important part of the overall development trend (see Figure 1). The Rast 2. The Rast connector system has made great efforts in standardization. Through-hole reflow soldering technology can be applied to specific technologies, so it can be used in basic pin insertion (PTH) connectors Design (see Table 2, Figure 4). Increased requirements. With the increasing number of functions assigned to home appliances, the number of connectors that realize the connection between the module function and the main control has also increased accordingly.
