To provide a trip lock terminal board having a pair of terminals fixed to a board and a short circuit plug connecting between the pair of terminals capable of not only efficiently connecting and disconnecting the pair of terminals but also surely checking a disconnecting state, and to attain downsizing.
The trip lock terminal board includes a first and a second terminals 110, 120 which are equipped with conductive shaft parts 111, 121, knob parts 113, 123 attached to tip sides of the shaft parts, and an elastic member 115 biasing a short circuit plug 130 connected between the shaft parts 111, 121 of the first and the second terminals 110, 120 so as not to be separated. A marker M is formed on the short circuit plug 130 checking that the short circuit plug 130 is not separated from the first and the second terminals 110, 120 by the elastic member 115 when the knob parts 113, 123 are turned to one direction. The short circuit plug 130 is divided into a first short circuit piece 131 and a second short circuit piece 132.
