Feed Through Terminal Block.
In the electrotechnics, the terminal refers to the terminal and is designed to run through the terminal production. The type is divided into single hole, double hole, socket, hook, etc. from the material, copper silver plating, copper zinc plating, copper, aluminum, iron, etc. their functions are mainly to transmit electrical signals or conduct electricity. The unit of terminal block is "bit", and one wiring bit is "bit". Usually the so-called table is the serial number of the terminal, which has different definitions in different applications. "Jie" and "bit" have the same meaning, but they are called differently. Groups are made up of sections.
