Abstract
An air-cooled switch relates to the technical field of switches, and comprises a columnar sealed container, wherein the upper and the lower ends of the columnar sealed container are provided with through holes, rubber pads which are matched with the through holes are installed in the through holes, metallic contacts are arranged in the rubber pads, electricity conducting liquid is contained in thecolumnar sealed container, a supporting rack extends on the columnar sealed container, a fan is arranged on the supporting rack, and the air-cooled switch has better explosion-proof property, and canbe automatically cooled.
Description
Technical field
The utility model relates to switch.
Background technology
Existing switch is made with copper sheet, utilize the copper sheet conduction, the time that this switch is used has been grown, will produce friction between the copper sheet, so, be to produce electric spark at make-and-break contact easily just, be used in factory etc. and contain the place of explosion hazard gases and just blast easily that explosion-proof performance is bad.
The utility model content
In order to overcome the bad deficiency of existing copper sheet switch explosion-proof performance, the utility model provides a kind of Wind-cooling type switch, and this Wind-cooling type switch has explosion-proof performance preferably, and can cool off automatically.
The utility model adopts following technical scheme, a kind of Wind-cooling type switch, comprise cylindrical closed vessel, the two ends up and down of cylindrical closed vessel have through hole, the rubber blanket that is complementary is installed in the through hole, is provided with hard contact in the rubber blanket, fill conducting liquid in the cylindrical closed vessel, be extended with bracing frame on the cylindrical closed vessel, bracing frame is provided with fan.
The beneficial effects of the utility model are, because this Wind-cooling type switch comprises cylindrical closed vessel, the two ends up and down of cylindrical closed vessel have through hole, the rubber blanket that is complementary is installed in the through hole, be provided with hard contact in the rubber blanket, fill conducting liquid in the cylindrical closed vessel, be extended with bracing frame on the cylindrical closed vessel, bracing frame is provided with fan.This Wind-cooling type switch has explosion-proof performance preferably, and can cool off automatically.
Description of drawings
Fig. 1 is the structural representation of the utility model Wind-cooling type switch;
Embodiment
As shown in Figure 1, a kind of Wind-cooling type switch, comprise cylindrical closed vessel 1, the two ends up and down of cylindrical closed vessel 1 have through hole, the rubber blanket 2 that is complementary is installed in the through hole, is provided with hard contact 3 in the rubber blanket 2, fill conducting liquid 4 in the cylindrical closed vessel 1, be extended with bracing frame 5 on the cylindrical closed vessel 1, bracing frame 5 is provided with fan 6.
Because fill mercury in the utility model cylindrical closed vessel 1, the two ends of cylindrical closed vessel 1 have can with the contacted hard contact 3 of mercury, in vertical state the time, the hard contact 3 of upper end does not contact with mercury at cylindrical closed vessel 1, and the utility model switch is off-state.When cylindrical closed vessel 1 was the level of state, the hard contact 3 at cylindrical closed vessel 1 two ends linked together with the mercury conductor, and promptly the utility model switch is opening.Therefore the utility model is safe, has explosion-proof performance preferably.Because bracing frame 5 is provided with fan 6, so this switch can cool off automatically.
Claims (1)
1, a kind of Wind-cooling type switch, comprise cylindrical closed vessel (1), it is characterized in that: the two ends up and down of cylindrical closed vessel (1) have through hole, the rubber blanket (2) that is complementary is installed in the through hole, be provided with hard contact (3) in the rubber blanket (2), fill conducting liquid (4) in the cylindrical closed vessel (1), be extended with bracing frame (5) on the cylindrical closed vessel (1), bracing frame (5) is provided with fan (6).
