TECHNICAL FIELD
[0001] The utility model belongs to the field of rectifier bridge, concretely relates to a rectifier bridge insulation withstand voltage test fixture. BACKGROUND
[0002] The rectifier bridge is an electronic circuit for converting alternating current into direct current, which is composed of four diodes connected in a specific way and belongs to a full-wave rectifier circuit.

The working indicator light in the present application is a diode indicator light. Each copper column and the probe connected to the copper column are connected in series with the working indicator light through the rectifier bridge bottom plate to form a working circuit. When the fixed plate is pressed down, the height of the lead-out electrode on the rectifier bridge is higher than the height of the bottom plate of the rectifier bridge. The probe corresponding to the lead-out electrode of the rectifier bridge first contacts the lead-out electrode of the rectifier bridge, and the probe corresponding to the rectifier bridge bottom plate contacts the rectifier bridge bottom plate through the copper column. When each copper column contacts the corresponding rectifier bridge bottom plate, the rectifier bridge bottom plate can act as a conductive electrode for the copper column, and the probes connected with the copper column are connected in series with each other to conduct, thereby making the working indicator light light up. Only when each copper column contacts the rectifier bridge bottom plate, the series circuit of the working indicator light is conducted, and the working indicator light lights up.
[0004] However, in actual use, the probes need to be placed through the fixed plate.
