Dimensional Drawing
Â
The terminal is used to facilitate the connection of wires. It is actually a piece of metal enclosed in insulating plastic. There are holes at both ends to insert wires. There are screws for fastening or loosening, such as two wires, sometimes Need to connect, sometimes need to be disconnected, then you can use the terminal to connect them, and can be disconnected at any time, without having to solder or twist them together, very convenient and fast.
