ABSTRACT:
A fuse inspection device having receiving terminals which are arranged in a longitudinal direction of a fuse box body and with which a plurality of band fuses are held in fit engagement. Windows are provided in side walls of accommodating chambers for the respective receiving terminals, and a slide knob slides along the band fuses. A sensing terminal moves together with the slide knob and has one end electrically connected with the receiving terminals through the window and has the other end brought into contact with a common conductive member. Electric conduction states of the band fuses are successively sensed by electrically connecting the sensing terminal and the receiving terminals through the movement of the slide knob. A plurality of connecting terminals each of which has one end held in contact with the corresponding receiving terminal through the window are arranged in ascendible fashion in the fuse box body and in a moving direction of the slide knob so that when one end of the sensing terminal has come into contact with any of the connecting terminals, the contact pressure between the other end of the sensing terminal and the conductive member rises, thereby to reliably sense the conduction state of the fuse.
