light-emitting anzeigevorrichtung of runaway fuses and their causes in elekrischen circuits of motor vehicles

摘要

Made up of a holder element (1) on which one or several detecting circuits (4) are assembled constituted by a lamp of LED diode connected in series to a Zener diode and a resistance, dimensioned in such a way that the LED turns on when the value of the impedance of the circuit to be protected is lower than a predetermined value. The detecting circuit (4) has two connecting tags (8) foreseen to hold the fuse element (2) itself, which being made up of a soft metal strip in the shape of an "H" is clamped by the holder (1) by means of a clamping mechanism made up of two stops (12) which are inserted into two slits (9) which the fuse element has and which can be released by pressing on the corresponding levers (5).
