Terminal Blocks - Headers, Plugs and Sockets are commonplace in electronic assembly industry for ease of manufacturing and replacement of components. 1821122 is a type of terminal blocks used in this industry. It is mainly used in power supplies and all types of embedded systems.

The product comprises of two distinct parts the header block and the plug/socket. The header block, made from gray phosphorous bronze, has slender, straight contacts and good electrical conductivity. It is designed to be inserted in PCB sockets. The plug/socket also made from gray phosphorous bronze ensures good electrical contact with the mating terminal and also helps in protection of wires from short circuits. Both parts are designed to be power transmitting and signify robust electrical contact.

The header block comprises of a body made from UL 94V-0 polyamide. It carries two pins and two sockets into which a spring contact is securely fitted. The spring contact is made from gray phosphorous bronze with two small notches into which the base spring is fitted. The contacts are fixed at the ends and these contacts have an insulation resistance of 1500MΩ. The plug/socket is designed to fit into the PCB slot and comprises of a plug body made from UL 94V-0 polyamide. It has a pair of stainless steel tangs on the top for easy connection with the contact.

The mechanical strength of the header block and the plug/socket ensures there is a robust electrical interconnectivity. The contact spring in the header block and the tangs on the plug/socket helps in sustained electrical connectivity and ensures more reliable operation.

The 1821122 terminal blocks therefore simplify assembly of components. It also ensures better performance while providing efficient electrical connection and protection. This connection is of the highest quality and can be used in a variety of applications. It is also widely used for providing stable power connection to the circuits.
