Specific embodiment
The utility model will be further described in conjunction with the embodiment in attached drawing below：
As shown in Figure 1, the utility model mainly includes touch switch 1, push rod component, tension spring 3, cover board 7,11 and of front supporting plate
Rear carrier plate 12.
Push rod component is equipped between touch switch 1 and cover board 7, end in contact touch switch 1 before push rod component, in push rod component
3 one end of tension spring is connected, 3 other end of tension spring connects front supporting plate 11.Under the effect of tension spring 3, push rod component sequentially passes through front supporting plate 11
With rear carrier plate 12 and hold out against contact cover board 7.
Spring base 8 is equipped between the tension spring 3 and front supporting plate 11, spring base 8 is fixed on front supporting plate 11, and tension spring 3 mounts
On spring base 8.
The push rod component includes preceding mandril 2 and pushing rod 6 of the front and back in straight line setting, preceding 2 front and back end of mandril difference
Contact touch switch 1 and 6 front end face of pushing rod.Mandril 2 and cover board 7 before 6 front and back end of pushing rod contacts respectively.
Front shaft sleeve 4 is equipped between the preceding mandril 2 and front supporting plate 11, front shaft sleeve 4 is fixed on front supporting plate 11, front shaft sleeve 4
Preceding copper sheathing 5 is equipped between preceding mandril 2.
Rear axle housing 9 is equipped between the pushing rod 6 and rear carrier plate 12, rear axle housing 9 is fixed on rear carrier plate 12, rear axle housing 9
Rear copper sheathing 10 is equipped between pushing rod 6.
The working principle of the utility model is：, when opening cover board, push rod component slides backward under the action of tension spring,
To be detached from touch switch, make corresponding main switch separating brake.Mandril leaves touch switch, and touch switch becomes normal by normally opened
It closes, because this contact is in parallel with main switch sub-gate circuit, so main switch separating brake.It completes and opens the function that cover board automatically powers off
Energy.
The utility model structure is simple, compact, reasonable, automatic when suitable for safeguarding that high voltage flameproof switch cabinet opens cover board
Power-off improves safety when maintenance.
