Abstract
The utility model discloses a magnetic button, comprising a left magnet and a right magnet; wherein, the magnetic poles of the magnets are deposited in a reverse direction, namely, half of the end face of the magnetic button is S pole, and the other half is N pole. The magnetic button has the advantages that: the magnetic flux leakage is avoided and the button has favorable magnetism.
Description
Technical field
The utility model relates to the fastener technical field of wrapping class, a kind of specifically magnetic clasp.
Background technology
On special use such as magnetic clasp extensive use mobile phone, digital camera, MP3/MP4, GPS, laptop computer or common leather sheath or the suitcase, because there is certain defective in the magnetic field of the magnetic clasp that adopts before, when you take electronic product, may cause abnormal phenomenons such as automatic open and close machine, signal difference, the improper demonstration of screen-picture or mess code because of the interference of magnetic.Also there be the antimagnetic leatherware of part by improveing in existing market, but this series products can only be accomplished the function that one side is antimagnetic, antimagnetic effect is also not ideal enough, as Fig. 1, the cardinal principle that it is antimagnetic: below the magnetic fastener, place iron plate and weaken magnetic to reach antimagnetic effect, this antimagnetic real demagnetizing effect that plays of failing, antimagnetic weak effect.Study for this reason and a kind ofly can prevent leakage field, and the good magnetic clasp of magnetic is an emphasis of the present utility model.
Summary of the invention
The purpose of this utility model is for providing a kind of leakage field that prevents, and the good magnetic clasp of magnetic.
The technical scheme that realizes the foregoing invention purpose is as follows:
Magnetic clasp is made up of left and right sides two parts magnet, and the magnetic pole of two parts magnet is placed upside down, promptly the end face of magnetic clasp half be the S utmost point, second half is the N utmost point.
Two parts magnet side, the described left and right sides and the back side are coated with antimagnetic iron plate.
The inner surface of described antimagnetic iron plate or outer surface, one side is coated with the zinc layer at least.
The surfaces externally and internally of described antimagnetic iron plate all is coated with the zinc layer.
The utility model takes two parts magnet to be placed upside down, and forms a pair of utmost point work pole-face, and magnetic line of force work distance shortens, and magnetic resistance reduces, and the magnetic line of force is more concentrated relatively, and the space leakage field reduces, and the magnetic circuit of composition more effectively and reasonably; Compare with original structure, under the prerequisite of equal volume magnet steel, magnetic energy is not fully exerted, and efficient improves, thereby makes the absorption affinity of this specific magnetic circuit assembly that this steel yoke is formed improve greatly, and stability strengthens.Further, on the magnetic structure after the improvement, put an antimagnetic iron cover again, formed a dual fail-safe and made the magnetic force of magnet steel form magnetic, played other faces demagnetizing effect more at single face at its reverse side.
Description of drawings
Fig. 1 cuts open figure and principle schematic for existing magnetic button structure on the market;
Fig. 2 cuts open figure and principle schematic for the structure of the utility model embodiment;
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 2, magnetic clasp is made up of left and right sides two parts magnet 1, and the magnetic pole of two parts magnet 1 is placed upside down, promptly the end face of magnetic clasp half be the S utmost point, second half is the N utmost point.
The magnetic line of force 4 work distances of the utility model magnetic clasp shorten, and magnetic resistance reduces, and the magnetic line of force is more concentrated relatively, and the space leakage field reduces, and the magnetic circuit of composition more effectively and reasonably.
Further, two parts magnet side, the described left and right sides and the back side are coated with antimagnetic iron plate 2.Make magnetic clasp except that the front, other faces are leakage field still less.
The inner surface of described antimagnetic iron plate or outer surface, one side is coated with the zinc layer at least.Be coated with the antimagnetic better effects if of zinc layer.
Present embodiment adopts surfaces externally and internally all to be coated with the antimagnetic iron plate of zinc layer 3.Antimagnetic better effects if.
Claims (4)
1. magnetic clasp, it is characterized by: be made up of left and right sides two parts magnet, the magnetic pole of two parts magnet is placed upside down, promptly the end face of magnetic clasp half be the S utmost point, second half is the N utmost point.
