Terminal Blocks - Barrier Blocks

Terminal blocks are electrical devices used to connect current and voltage sources with electrical loads in a safe and convenient way. They provide a secure and reliable connection between wires and components. Barrier blocks are one type of terminal blocks, which are defined by the presence of an insulated barrier that separates lower voltage sources from potentially dangerous higher voltage sources.CB21420907 is one such barrier block. Its application field includes industrial machinery, electronics, automotive, and commercial and consumer applications. In industrial machinery, it can be used to protect machine wiring from risk of damage caused by oil or water infiltration. In automotive applications, it can be used to protect sensitive electrical components from corrosion and voltage interference. In electronics, it can be used to provide better signal transmission between components, while in commercial and consumer applications, CB21420907 can be used to power battery packs and power supplies.A barrier block is comprised of two parts - an insulating barrier and an electrical contact portion. The insulating barrier prevents arcing between the electrical source and the contact portion, while the contact portion integrates the connection between the wires and the electrical source. The contact portion of the CB21420907 is made of insulated copper alloy for corrosion protection and enhanced electrical conductivity. The contact portion consists of saw-tooth like layers of stainless steel that ensure reliable and secure contact between the wires and the electrical source.Additionally, the CB21420907 is designed to meet safety standards such as UL, RoHS, and CE. The UL certification ensures the product meets all safety requirements and regulations, while the RoHS certification ensures it does not contain hazardous substances such as lead, mercury, and cadmium. The CE certification ensures the product is manufacturered in accordance with all applicable European regulations.The working principle of a CB21420907 barrier block is relatively simple. When connected to a power source, the electric current flows through the contact portion and is blocked by the insulating barrier. This ensures that the power source is protected from overvoltage, while the connected wires or components receive the desired amount of power.In conclusion, the CB21420907 barrier block is an ideal solution for industrial, automotive, electronics, and commercial and consumer applications. Its insulated barrier ensures safe and secure connections between power sources and electrical loads, while its contact portion ensures consistent performance across various temperatures and humidity levels. Moreover, its UL, RoHS, and CE certification ensures the product meets all safety and manufacturing requirements.
