Detailed Description

The following describes the specific contents of the present invention in detail by using specific embodiments with reference to fig. 1~6. The power supply system ground control indicating lamp box mainly comprises a front cover assembly 1 and a rear cover assembly 2 which are in embedded fit. It is used for installation, fixed spare part, components and parts as product main part bearing structure to play protective structure inside and avoid receiving the corruption, strengthen the heat dissipation, provide purposes such as product mechanical interface.

The front cover assembly 1 comprises a semi-closed front cover body 11, a plurality of element limiting holes 16 arranged on a panel of the front cover body 11 at intervals, an indicator lamp 12, a potentiometer 13 and a button switch 14 which are assembled on the element limiting holes 16, a plurality of weight-reducing grooves 15 arranged on the side wall of the front cover body 11 along the circumferential direction of the side wall, front cover assembly holes 18 arranged along the circumferential direction of the side wall and used for matching with the rear cover assembly 2, and side lugs (not marked in the figure) arranged on the side part of the panel and provided with fixing holes 17. The indicator light 12, the potentiometer 13 and the toggle switch 14 are preferably soldered connections.
