Abstract
The invention discloses a surge protector with a protection module capable of being plugged without interrupting signals. The surge protector is mainly composed of a terminal base and a module plug, wherein the module plug is connected with the terminal base in a pluggable mode and is provided with a protection element. The terminal base comprises at least one short circuit sheet. Each short circuit sheet is provided with at least one metal sheet in a locating mode. The terminal base is provided with terminal sets and elastic clamp sets, wherein one terminal set and one elastic clamp set correspond to one metal sheet. Each terminal set comprises a first terminal and a second terminal. Each elastic clamp set comprises a first elastic clamp and a second elastic clamp. PCBs corresponding to the short circuit sheets respectively are arranged in the module plug in a locating mode. Each PCB is provided with two inserts corresponding to one metal sheet in a spaced mode. When the surge protector is damaged and needs replacing, there is no need to dismantle the terminal base connected with a wire, only the protection module mounted on the terminal base in a pluggable mode needs to be replaced, and the signals can not be interrupted in the replacing process of the protection module, so working time is saved, and replacement cost can be lowered.
