DEVICE FOR SENSING LOOSENING OF A TERMINAL OF AN ELECTRIC DEVICE FOR AN INTERNAL COMBUSTION ENGINE, PREVENTING THE LIFE SPAN OF THE ELECTRIC DEVICE FROM BEING SHORTENED BY A SUPERHEAT PRODUCED FROM A TERMINAL CONNECTION PART AND PREVENTING A FIRE FROM BRAKING OUT

摘要

PURPOSE: A device for sensing loosening of a terminal of an electric device for an internal combustion engine is provided to enable a driver to discern the terminal is normally fastened at a glance from a driver's seat by installing a device for ascertaining a fastened state of the terminal. CONSTITUTION: A device for sensing loosening of a terminal(12) of an electric device for an internal combustion engine comprises a housing(11) of a case shape; sensing terminals(13) moving to the upper and lower sides of the housing according to a fastened degree of the terminal; a bolt(15) fixed to the top of the sensing terminals; nut stoppers fixed to the housing to be situated to the upper side of the sensing terminals, to suppress the fastened degree of a nut(14); an elastic member(17) installed between the sensing terminals and the nut stopper to deviate the sensing terminals downward; a sensing unit sensing the fastened degree of the terminal; and a warning unit warning the outside of the sensing result of the sensing unit. The sensing terminals are installed in the housing in a state capable of moving up and down. The terminal is fitted to the bolt and the nut is combined to the bolt.
