## Abstract

A locking confirmation device of multiple electrode contacts includes an electrode, a terminal bolt, a sensing unit and a positioning bolt. The electrode includes an electrode thread and a positioning thread. The terminal bolt is used for locking a conductor and the electrode thread. The terminal bolt includes a positioning recess. The sensing unit includes an insulated cover, a first contact, a second contact, an elastic member and an voltage signal input connector. When the elastic member is extruded, a circuit is formed for returning a voltage signal of a node of the electrode. The positioning bolt is used for fixing a detection sensor assembly on the positioning thread. When a head portion of the positioning bolt is received within the positioning recess, the terminal bolt is led to a locking state by the head portion of the positioning bolt. Therefore, a fault of an electricity system is prevented.
