Abstract
A filled explosion-proof switch relates to the technical field of switches. The explosion-proof switch comprises a cylindrical closed container, wherein through holes are formed at the upper end and the lower end of the cylindrical closed container; rubber pads which are matched with each other are mounted in the through holes; a metal contact point is arranged in each rubber pad; a conducting liquid is filled in the cylindrical closed container; and a filling material is arranged on the inner side of the cylindrical closed container. The filled explosion-proof switch is provided with better explosion-proof performance, and can save the conducting liquid.
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 filled type flame-proof switch, and this filled type flame-proof switch has explosion-proof performance preferably, can save conducting liquid again.
The utility model adopts following technical scheme, a kind of filled type flame-proof 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, be provided with hard contact in the rubber blanket, fill conducting liquid in the cylindrical closed vessel, the cylindrical closed vessel inboard is provided with filler.
The beneficial effects of the utility model are, because this filled type flame-proof 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, the cylindrical closed vessel inboard is provided with filler.Therefore, this filled type flame-proof switch has explosion-proof performance preferably, can save conducting liquid again.
Description of drawings
Fig. 1 is the structural representation of the utility model filled type flame-proof switch;
Embodiment
As shown in Figure 1, a kind of filled type flame-proof 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, be provided with hard contact 3 in the rubber blanket 2, fill conducting liquid 5 in the cylindrical closed vessel 1, cylindrical closed vessel 1 inboard is provided with filler 4.Wherein, conducting liquid 5 is a mercury.
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.Because cylindrical closed vessel 1 inboard is provided with filler 4, therefore, so the utility model is safe, has explosion-proof performance preferably, can save conducting liquid again.
Claims (1)
1, a kind of filled type flame-proof 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 (5) in the cylindrical closed vessel (1), cylindrical closed vessel (1) inboard is provided with filler (4).
