With the rise of household appliances, as early as the 1970s, in order to reduce the work intensity of first-line workers and reduce product damage caused by connector misinsertion rates, the overall processing cost was reduced. So, Europe began to gradually introduce a new product, that is RAST connector. At present, RAST connector technology/concept is widely used in traditional superior industries such as automobiles, HVAC and household appliances. There are many types of the rast connectors. I will introduce them in this article.

The RAST connector officially became the international terminal block standard in the household appliance market in the 1980s. It usually uses insulation displacement (IDC) crimping technology to simplify and speed up the harness processing process. This connection technology (Grid Connection Plug Technology) makes the past processing process. It requires the cutting of single wires, stripping and crimping, and the potential for potential failures introduced by these manual termination processes to be minimized, which can achieve large-scale fully automated assembly and testing, and improve the quality of the rast connectors. RAST connectors usually include a number in their name (eg RAST5 connector) to show the terminal spacing (eg 5 mm).
The RAST connector word is said to be an initial letter combination from the German Raster (bar grid) + Anschluss (combination) + Steck (superposition) + Technik (technology). The mainstream of the RAST connector products are generally RAST2.5 and RAST5.0, which represent the spacing of 2.5 and 5.0 mm respectively (there is also RAST2.5 which is 5.0 spacing). Since it is a wire-to-board connector, there are IDC (Insulation Displacement Connection) method, traditional crimping method and lock screw method. Because the IDC method is suitable for automatic/semi-automatic machine crimping, it greatly improves production efficiency, improves product consistency, and reduces error rates and costs.
Obviously, the RAST connectors can also be classified according to the different usage scenarios. I will show you the details as follows.
1.The RAST 5 Timer connector system is designed to provide a safe and reliable power connection for RAST 5 components in household appliances including indoor air conditioners. The nylon housing of the system meets GWT and UL94 V-0 flame retardant requirements. Integrated terminals Position (TPA) mechanism is used to ensure that the contact is fully seated, and provides additional measures to prevent the contact from falling off, and the use of a latch helps prevent accidental disconnection. The shell also has multiple keying options.
2. RAST 2.5, RAST 5 and RAST power connector product line. It is converted into an extremely reliable product that meets a wide range of international design compatibility GWT and UL94 V-0 flame retardant requirements, and provides a range of design current ratings to enhance automotive lighting applications and various household appliances (including washing machines and washing machines) ) flexibility.
3. The RAST 5 PCB connector system is designed to meet the requirements of the heating industry, and offers a variety of color coding possibilities, as well as custom labeling options, enabling high levels of variability for quick, easy, and accurate identification in complex systems.
4. RARSF RAST connector is a right angle RAST 5 connector designed for household appliances. The low-insertion right-angle RAST connector can be quickly and easily matched to the standard convex tabs on the PCB, simplifying wiring harness wiring in narrow spaces, and adopting a reliable locking mechanism to prevent accidental detachment.
As far as I am concerned, after reading this article, you will know most kinds of the rast connector.
