Therefore, the utility model is not only suitable for the signal control of small current, but also suitable for the power control of large current; meanwhile, the device has the characteristics of small volume, low cost and simple structure.
Description
Technical field
The utility model relates to electric switch, is a kind of magnetic micromotion switch specifically.
Background technology
All to be outer mechanical force be used to move reed by actuated element (push-piece, button, lever, roller etc.) with masterpiece with sensitive switch in the market, and with energy accumulation after critical point, produce instantaneous operation, the moving contact and the fixed contact of action reed end are switched on or switched off fast.After the active force on the actuated element was removed, the action reed produced counteragent power, reach the action critical point of reed when the actuated element reverse stroke after, the instantaneous counteragent of finishing.This sensitive switch is that contact is transmitted power, and along with consumer's quality of life improves, more and more higher to the profile and the quality requirements of product, this contactless switch of magnetic red pipe is widely used, but the magnetic red pipe can not pass through big electric current, and the scope of application also is restricted.The flame-proof switch of ZL01215049.5, reality also are the switches that a kind of contact passes relay, and volume is big, cost height, complex structure; The non-contact card of ZL200520102756.3 is near sense switch, and is contactless between movable contact spring and static contact, and easy-to-draw arc guide causes wearing and tearing during by big electric current, and the life-span is short, even arcing can occur and be sticked together and security incident occurs.Active and static contact is not in seal, inert free gas, even by little electric current, the active and static contact material can cause loose contact because of surface oxidation.
The utility model content
The purpose of this utility model is to overcome the defective that above-mentioned prior art exists, and a kind of noncontact magnetic sensitive switch is provided, and both is suitable for the signal controlling of little electric current, and also the volume of the power of suitable big electric current control is little, and cost is low, magnetic micromotion switch simple in structure.
Realize the technical scheme of the utility model purpose: comprise shell, static contact, movable contact spring, be fixed with fixed contact on the static contact, it is characterized in that, the static contact below is provided with movable contact spring, is provided with magnet between movable contact spring and shell.
Also include the movable contact spring return unit in the technique scheme.
In the technique scheme, movable contact spring and magnet can be designed to integrative-structure.
In the technique scheme, the quantity of static contact and movable contact spring is at least one separately.
In the technique scheme, static contact and movable contact spring respectively are one, and described movable contact spring is provided with moving contact, the position of fixed contact on the corresponding static contact in the position of moving contact.
In the technique scheme, static contact is for disconnecting and two arranged side by side, each static contact is provided with a fixed contact, movable contact spring is one, its length is greater than the distance between two fixed contacts, movable contact spring is provided with two moving contacts, the position of fixed contact on corresponding respectively two static contacts in the position of two moving contacts.
In the technique scheme, also can be: static contact be for disconnecting and two arranged side by side, and each static contact is provided with a fixed contact, and movable contact spring is one, and its length is greater than the distance between two fixed contacts.
For guaranteeing the orientation of described magnet in motion process, described shell is provided with places the gathering sill that magnet and magnet can move within it, and magnet is placed in the gathering sill.
Above-mentioned movable contact spring return unit is to be arranged on flexible members such as spring between movable contact spring and the shell or shell fragment.Or return unit and movable contact spring be structure as a whole, as movable contact spring itself is made as elastic construction;
Described shell is that non-magnetic conductive material that make or nonmetal that plastics are made or ceramic is made.
The beneficial effects of the utility model are, owing to be provided with magnet between movable contact spring and shell, utilize magnet and the magnet same sex is repelled each other He there is a natural attraction between the sexes active force to realize contactless the switching on and off of sensitive switch of controlling.When magnetic switch external magnet during near switch, the magnet in the switch moves because of being subjected to the active force that there is a natural attraction between the sexes or the same sex is repelled each other, and drives movable contact spring simultaneously and moves, by the contact condition of change movable contact spring and fixed contact, with the connecting and disconnecting of realization switch.The utility model both had been suitable for the signal controlling of little electric current, also was suitable for the power control of big electric current; It is little also to have volume simultaneously, and cost is low, characteristic of simple structure.

Fig. 2 is the structural representation of the utility model embodiment two;
Fig. 3 is the structural representation of the utility model embodiment three.
Embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is further described.
Embodiment one:
As shown in Figure 1, the utility model magnetic micromotion switch comprises shell 1, movable contact spring 2, magnet 3, static contact 4, elastic reset spare 5, fixed contact 6 and moving contact 7, and moving contact 7 is in normally open with fixed contact 6.Elastic reset spare 5 is arranged between movable contact spring 7 and the shell 1.Magnet 3 is placed in the gathering sill 11 of shell 1, when having magnet close at the top of shell 1, magnet 3 moves up at the active force lower edge gathering sill 11 that there is a natural attraction between the sexes, with upwards distortion of movable contact spring 2, moving contact 7 and fixed contact 6 closed connections, after the top magnet of shell 1 was removed, the active force of magnet 3 disappeared, and movable contact spring 2 makes moving contact 7 and fixed contact 6 instantaneous disconnections under 5 effects of elastic reset spare; In the present embodiment, elastic reset spare 5 is spring or shell fragment, and described shell 1 is made of plastics.
The present embodiment making that elastic reset spare 5 and movable contact spring 2 can also be combined, be about to movable contact spring 2 and itself be made into the rubber-like element, so that after the top magnet of shell 1 is removed, the active force of magnet 3 disappears, movable contact spring 2 is subjected to self flexible influence and resets, and impels moving contact 7 and fixed contact 6 instantaneous disconnections.
Embodiment two:
As shown in Figure 2, the present embodiment difference from Example 1 is that magnet 3 and movable contact spring 2 link together, and does not have movable contact spring elastic reset spare 5.Static contact 4 is for disconnecting and two arranged side by side, each static contact 4 is provided with a fixed contact 6, and movable contact spring 2 is one, and its length is greater than the distance between two fixed contacts 6, movable contact spring 2 is provided with the position of fixed contact 6 on respectively corresponding two static contacts 4 in position of 7, two moving contacts 7 of two moving contacts.
When having magnet close in the bottom of shell 1, magnet 3 moves up under the active force that the same sex is repelled each other, and movable contact spring 2 is pushed to moving contact 7 and fixed contact 6 closed connections; After the magnet of the bottom of shell 1 was removed, the active force that is subjected to of magnet 3 disappeared, and magnet 3 disconnects because of the self gravitation effect makes moving contact 7 and fixed contact 6 with the combination of movable contact spring 2.
Embodiment three:
As shown in Figure 3, the difference of present embodiment and embodiment two is, movable contact spring 2 and magnet 3 are united two into one, and promptly adopts the materials processing making that possesses conduction, magnetic property, and do not establish moving contact.Its operation principle is consistent with the content of embodiment two.
