Abstract
The invention discloses an air switch, belongs to the field of electrical equipment. The air switch comprises a casing, threaded holes are symmetrically arranged at positions near to the two ends at the front surface of the casing, the middle portion between the threaded holes at the two ends of the front end surface of the casing is provided with a boss, the middle portion of the rear end surface of the casing is provided with a groove, a switching device and a bearing platform connected with the switching device are arranged on the boss, the switching device comprises a toggle switch and a soleplate, the toggle switch is mounted in the soleplate in an overturnable manner and enables the soleplate to abut against the bearing platform, and an arc-shaped groove is formed in the end portion of the bearing platform. On the basis of a traditional air switch, the bearing platform is additionally arranged on the boss to increase the bearing area and reduce damage on the toggle switch, and influence on the service life of the air switch is avoided.
Description
Technical field
The present invention relates to electrical equipment, be specifically related to a kind of air switch.
Background technology
Air switch, has another name called air circuit, is the one of circuit breaker, as long as be that in a kind of circuit, electric current exceedes the switch that rated current will disconnect automatically.Air switch is very important a kind of electrical equipment in low voltage power distribution network and electric drive system, and it integrates control and multi-protective function.Decapacitation completes outside contact and point deenergizing, and the short circuit that still can occur circuit or electric equipment, heavy overload and under voltage etc. are protected, and also may be used for infrequently actuating motor simultaneously.Existing air switch is when automatic Closing Switch, plate button very promptly can clash into bullet and close and cut out with air switch convex platform, bear huge active force in the plate button short time, and this model button can be easy to fracture, air switch has just been scrapped, and affects the useful life of whole air switch.
Summary of the invention
Problem to be solved by this invention is: provide a kind of air switch, and it can reduce air switch and close the injury caused plate button, avoids its impact on air switch useful life.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of air switch, comprise housing, described housing forward end face is arranged with screwed hole near two ends place, housing forward end Middle face between described screwed hole is provided with boss, described housing rear end Middle face is provided with groove, and described boss is provided with switching device and weighted table, and described weighted table is connected with switching device, described switching device comprises plate button and mount pad, and described plate button is turnover to be arranged in mount pad and to make it can against weighted table.
Preferably, described weighted table end opens has arc groove.
The invention has the beneficial effects as follows: the present invention, on the basis of conventional air switch, weighted table is set up by boss, increase the injury that lifting surface area reduces suffered by plate button, avoid its impact on air switch useful life.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention.
Number in the figure: 1 is housing, 11 is boss, and 12 is screwed hole, and 13 is groove, and 14 is switching device, and 15 is weighted table, and 16 is plate button, and 17 is mount pad, and 18 is arc groove.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
As shown in Figure 1, a kind of air switch, comprise housing 1, described housing 1 front end face is arranged with screwed hole 12 near two ends place, boss 11 is provided with in the middle part of housing 1 front end face between described screwed hole 12, groove 13 is provided with in the middle part of described housing 1 rear end face, described boss 11 is provided with switching device 14 and weighted table 15, described weighted table 15 is connected with switching device 14, described switching device 14 comprises plate button 16 and mount pad 17, and described plate button 16 is turnover to be arranged in mount pad 17 and to make it can against weighted table 15.
During specific design, described weighted table 15 end opens has arc groove 18.
The present invention proposes a kind of air switch.The present invention is directed to the deficiencies in the prior art mentioned in background technology, on the basis of existing technology, boss 11 is set up weighted table 15, and plate button 16 can against weighted table 15, weighted table 15 end also offers arc groove 18, like this at plate button 16 under the constant prerequisite of stressed size, the lifting surface area increasing plate button 16 reduces the injury suffered by it, avoids its impact on the air switch life-span.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
Claims (2)
1. an air switch, comprise housing, described housing forward end face is arranged with screwed hole near two ends place, housing forward end Middle face between described screwed hole is provided with boss, and described housing rear end Middle face is provided with groove, it is characterized in that, described boss is provided with switching device and weighted table, described weighted table is connected with switching device, and described switching device comprises plate button and mount pad, and described plate button is turnover to be arranged in mount pad and to make it can against weighted table.
2. a kind of air switch according to claim 1, is characterized in that, described weighted table end opens has arc groove.
