[0002] The terminal block is used to facilitate the connection of wires. It is actually a piece of metal sheet sealed in insulating plastic. There are holes at both ends for inserting wires and screws for tightening or loosening. For example, two wires sometimes need to be connected and sometimes need to be disconnected. At this time, they can be connected with terminals and can be disconnected at any time without welding or wrapping them together. It is very convenient and fast, and suitable for interconnecting a large number of wires. In the power industry, there are special terminal blocks and terminal boxes, which are all wiring terminals, single-layer, double-layer, current, voltage, ordinary, breakable, etc. A certain crimping area is to ensure reliable contact and to ensure that enough current can pass. Therefore, the demand for a low-voltage dual power switch terminal is growing.

[0003] When plugging in, the plug-in terminals are usually directly plugged in and limited by friction. In order to improve the stability of the plug-in, threaded rods are usually set on both sides of the terminal block for threaded fixation. Due to the limited space on both sides of the terminal block, the threaded rods are set small, and the operation is extremely inconvenient when rotating to limit the position, which needs to be improved.
