Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example one

Referring to fig. 1 and 2, a high-insulation isolation capacitor mounting structure disclosed by the present invention comprises a PCB board 1, wherein a capacitor 5 is welded on the PCB board 1; wherein, for the safe distance between two terminals of reinforcing electric capacity 5, PCB board 1 has been close to electric capacity 5's side and has been seted up safe groove 2, safe groove 2's the perpendicular electric capacity 5's of extending direction installation direction, and has been filled with the insulating cement in the safe groove 2, and the insulating cement surpasss safe groove 2 to wrap up electric capacity 5.

The creepage distance of the capacitor 5 terminal is increased by the safety groove 2, and the resistance between the safety grooves 2 is increased by the insulating glue, so that the safety distance between two ends of the capacitor 5 terminal is increased, and the safe operation of the capacitor 5 is ensured; and after the insulating glue wraps up the capacitor 5, the external damage to the capacitor 5 can be reduced, and the service life of the capacitor 5 is prolonged.
