Abstract
A kind of safety switch of the explosion-proof high reliability of water proof and dust proof, it is to adapt to the requirement of the extreme environments such as high temperature, high pressure, using magnetic drive pattern, it is moved by magnetic drive intermediate active contact, it realizes and fixed contact is contacting and separating, to reach the open and close of circuit, and all contacts all be fully sealed, explosion-proof, anti-high pressure, the work of the enclosure interior of insulating properties, thus there is high safety；The structure easily to break down due to eliminating traditional pressure distortion element, elastic sealing elements etc., such no fatigue limit of switch can continuous in the presence of a harsh environment, long-time, high-frequency, heavy load work.
Description
Technical field
It is a kind of there is waterproof and dustproof, explosion-proof, heat safe power switch the present invention relates to electric power, appliance field.
Background technology
Switch is a kind of power equipment commonly element, usually there is fixed contact, armature contact, elastic device and pressure dress
Composition is set, under pressure, elastic device deforms, and armature contact is contacted with fixed contact, circuit turn-on；Cancelling
After pressure, elastic device resets, and circuit is disconnected, to realize that the break-make to circuit controls.
Current water proof switch is typically all that the external world is isolated by elastic material, and water is allowed to be unable to the mode inside access switch
Realize water-proof function.Under the effect of the pressure, elastic material deforms upon, and the contact of switch internal is connected, realizes circuit
Conducting.There are two security risks for the water proof switch of this mode：The first, the ageing failure of elaxtic seal；The second, high
Elastic material deformation failure under pressure condition also results in switch malfunction.It is limited by design principle, the switch nothing of this type
Method uses under conditions of deep-sea, high pressure.Meanwhile in an environment of high temperature, the elastic packing of switch can also lose in aging quickly
Effect, causes switch internal to be intake, loses water-proof function, lead to the generation of accident.
It extreme environment elastic part fatigue can not be lost in the spaces such as high temperature, high pressure to solve common water proof switch
Effect and the problem of sealing ring ageing failure, the present invention uses new on-off principle, eliminates usually used elastic part and close
Seal so that no fatigue limit is switched, without sealing device, so as to reach highest security level.
Invention content
The object of the present invention is to provide a kind of use electric connection mode of high security, electrical using the manufacture of this technology opens
It closes, there is high safety, can be used safely in the ultra-hostile environment (UHE)s such as high pressure, deep-sea, high temperature, inflammable gas.
A kind of safety switch of the explosion-proof high reliability of water proof and dust proof, it is characterised in that magnetic drive pattern is used, by magnetic
Power drive intermediate active contact is moved, and realizes and fixed contact is contacting and separating, to reach the open and close of circuit, and institute
Some contacts all be fully sealed, the work of explosion-proof, anti-high pressure, the enclosure interior of insulating properties, thus there is high safety；By
In the structure for eliminating traditional pressure distortion element, elastic sealing elements etc. and easily breaking down, such switch is without tired pole
Limit, can continuous in the presence of a harsh environment, long-time, high-frequency, heavy load work.
The present invention adopts the following technical solutions to realize：
A kind of safety switch of the explosion-proof high reliability of water proof and dust proof is by explosion-proof casing, sliding magnet, resets iron block, normally closed tactile
Point, common, sliding contact, normally opened contact composition；Wherein normally-closed contact, common and normally opened contact have been fixedly mounted on
In hermetically sealed explosion-proof casing inner cavity, sliding contact is permanently connected to common, and can be in normally opened contact and normally-closed contact
Between slide, the movement of sliding contact can be switched on or switched off common and normally opened contact（Or normally-closed contact）Circuit connect
It connects, to realize switching function；Sliding magnet is mounted in the sliding groove of the shell of the half opening on the outside of sliding contact, and can be with
It is moved in sliding groove；Sliding magnet move when, magneticaction drive next door sliding contact movement, realize circuit disconnection and
Turn-on power loss；One end that iron block is fixed on sliding groove is resetted, not when the effect of external force, sliding magnet is always leaned on reset iron block
Together, so that sliding contact is contacted with normally-closed contact, normally-closed circuit is formed.
Preferably, the length of the sliding contact is more than the length of sliding magnet.
Preferably, the sliding contact is formed by the high conductive corrosion-resistant Material cladding such as magnet, iron, silver, platinum.
Secondary selection of land, the sliding contact can also be to be made by the single magnetic material such as conducting magnetic iron, iron, nickel.
Preferably, the common, normally opened contact, normally-closed contact are highly conductive, anti-corrosive properties by silver, platinum, graphene etc.
Material is made.
Secondary selection of land, the common, normally opened contact, normally-closed contact can be also made by cheap metals such as copper, aluminium.
Preferably, the explosion-proof casing is made of high temperature resistant, high pressure, waterproof, fire-retardant insulating materials.
Preferably, full of inert gases or insulating oils such as nitrogen, argon gas in the explosion-proof casing closing inner chamber.
Description of the drawings：
Fig. 1 is the front view of the present invention.
Specific implementation mode
Principle according to the present invention, a kind of safety switch example of the explosion-proof high reliability of water proof and dust proof are as follows：
Example 1
As shown in Fig. 1, a kind of safety switch of the explosion-proof high reliability of water proof and dust proof, by by explosion-proof casing 1, sliding magnet 2, multiple
Position iron block 3, normally-closed contact 4, common 5, sliding contact 6, normally opened contact 7 form
Wherein normally-closed contact 4, common 5, sliding contact 6 and normally opened contact 7 are mounted on 1 inner cavity of explosion-proof casing being fully sealed
In, the movement of sliding contact 6 can be switched on or switched off common 6 and normally opened contact 7（Or normally-closed contact 4）Circuit connection,
Realize switching function；Sliding magnet 2 is mounted in the sliding groove of the half opening on the outside of sliding contact, and can be moved in sliding groove
Dynamic, magneticaction drives the sliding contact 6 in next door to move when sliding magnet 2 moves, and realizes the off and on function of circuit；It is multiple
Position iron block 3 is fixed on one end of shell sliding groove, and not when the effect of external force, sliding magnet 2 always leans against one with reset iron block 3
It rises, so that sliding contact 6 is contacted with normally-closed contact 4, forms normally-closed circuit.
Under the action of sliding magnet 2 is by thrust, separated with iron block 3 is resetted, sliding contact 6 attracts in sliding magnet 2
It moves to side under the action of power, is disconnected with normally-closed contact 4, when sliding magnet 2 is moved to the other end of sliding groove, sliding is touched
Point 6 is closed with normally opened contact 7, the normally opened circuit turn-on that common 5 is constituted with normally opened contact 7.
The foregoing describe the basic principles and main features and advantages of the present invention of the present invention.The technical staff of the industry answers
The understanding, the present invention is not limited to the above embodiments, and the above embodiments and description only describe of the invention former
A kind of applicable cases of reason only change quantity, shape, material, the peace of component without departing from the principle of the present invention
Dress mode, size, the parameters such as move mode, these changes and improvements belong to the scope of the present invention.
