Electrical terminal blocks (also known as terminal junction blocks, junction blocks, or barrier blocks) are devices used for safely, conveniently and efficiently connecting together one or more pairs of wires or cables. Terminal blocks are utilized in the telecommunications industry to provide an efficient connection for individual wires, line or conductors to individual pairs of lines of a multi-pair cable. Terminal blocks generally are configured as standard, multi-chambered units which terminate either 5, 10 or 25 wire pairs. Terminal blocks are generally of different lengths depending upon requirements at a particular site. Also, terminal blocks are often used outdoors which require sealing of the electrical connections against adverse environmental conditions, especially moisture. The typical terminal block utilizes insulation displacement connectors sometimes called clips to make the connection. A common type of terminal connector for connecting electrical wiring is the fast-on connector in which a female connector slides on and clamps a male terminal blade. A variety of terminal block assemblies have been introduced that include one or more filter elements coupled to electrical terminal elements for removing undesirable frequency transmission through the terminal block.
