Detailed Description

Example 1

Fig. 2 is a schematic structural diagram of a micro switch for a mouse according to the first embodiment. As shown in fig. 2, the micro switch for a mouse of the present embodiment includes a movable reed 1, a base 2, an operation lever 3, a fixing structure 4, and a limiting structure 5. The movable reed 1 lower surface is provided with the support shell fragment 12, and the one end of support shell fragment 12 is fixed at the middle part of movable reed 1, and fixed knot constructs 4 and is used for supporting the one end of action bars 1 and the other end of support shell fragment 12, and the basement 2 is located the below of the action bars 1 other end, and the lower surface of the action bars 1 other end has welded movable end contact 11, and the upper surface of basement 2 has welded quiet end contact 21, and action bars 3 are located movable reed 1 top to action bars 3 include insulating contact 31 and magnetic structure 32, and insulating contact 31 protrusion is in the bottom of magnetic structure 32.

With the micro-switch mouse shown in fig. 2, when the mouse button is pressed, the operation rod 1 moves downward, so that the insulating contact 31 generates downward pressure on the movable reed 1, so that the movable reed 1 is recessed downward, and the movable end contact 11 is driven to move downward and contact with the stationary end contact 21. In the above-mentioned micro-gap switch, the movable reed 1 is made of iron material, and the magnetic structure 32 can generate upward attraction force to the movable reed 1, so that the movable reed 1 can be restrained from sinking downwards to a certain extent, the problem that the movable end contact 11 and the stationary end contact 21 are in poor contact due to deformation of the movable reed 1 after the mouse is used for a long time is avoided, and the service life of the mouse is prolonged.

In the first implementation manner, the magnetic structure 32 is a conventional magnet, and the magnetic structure 32 may have various shapes such as a cylinder, a cuboid, or a triangular prism, and the specific shape of the magnetic structure 32 is not limited in this application. As shown in fig. 2, the insulating contact 31 is fixed at the bottom of the magnetic structure 32, and the operating rod 3 has the advantages of low cost, difficulty in falling off of the insulating contact 31 and stable structure.

In the second implementation manner, the magnetic structure 32 is a conventional magnet, and the magnetic structure 32 may have various shapes such as a cylinder, a cuboid, or a triangular prism, and the specific shape of the magnetic structure 32 is not limited in this application. The insulated contacts 31 are fixed to the side surfaces of the magnetic structure 32, and as shown in fig. 3, the bottom surfaces of the insulated contacts 31 are lower than the bottom surfaces of the magnetic structure 32. The advantage of such an operating lever 3 is that it is low in cost, simple in manufacturing process and easy to operate.

In the third implementation manner, the magnetic structure 32 is a conventional magnet, and the magnetic structure 32 may have various shapes such as a cylinder, a cuboid, or a triangular prism, and the specific shape of the magnetic structure 32 is not limited in this application. As shown in fig. 4, the insulating contact 31 is cylindrical, the magnetic structure 32 is in a circular tube shape, and the magnetic structure 32 is sleeved and fixed outside the insulating contact 31. The operating lever 3 has the advantage that the insulating contact 31 coincides with the axis of the magnetic structure 32, and the insulating contact 31 coincides with the center point of the acting force of the magnetic structure 32 on the movable reed 1, so that the deformation of the movable reed 1 can be suppressed to the maximum.

In a fourth implementation manner, the magnetic structure 32 is implemented by an electromagnet, and the power supply of the electromagnet may be an independent power supply or a power supply led out from an original circuit inside the mouse. The switch in the electromagnet power supply loop adopts a mechanical switch which is arranged on the mouse shell. After the mouse is used for a long time, the movable reed 1 deforms, so that the movable end contact 11 and the fixed end contact 21 cannot be contacted when a mouse button is pressed, at this time, a mechanical switch can be controlled to supply power to a coil of an electromagnet, after current is generated in the coil, the electromagnet generates strong attractive force to the movable reed 1 below, so that the movable reed 1 arches upwards for a period of time (for example, 1 minute, the time depends on factors such as the attractive force of the electromagnet to the movable reed 1 below, the elasticity of the movable reed 1, the deformation degree of the movable reed 1 and the like), and then a power supply loop of the electromagnet is disconnected again through controlling the mechanical switch, so that the electromagnet loses magnetism. The movable reed 1 returns to the original position. The operating rod 3 has the advantages that parameters of the electromagnet can be selected according to actual conditions, so that the electromagnet can generate larger magnetic force, and the problem that the movable reed 1 deforms is effectively solved.

In a fifth implementation manner, the magnetic structure 32 is implemented by an electromagnet, and the power supply of the electromagnet may be an independent power supply or a power supply led out from an original circuit inside the mouse. The switch in the electromagnet power supply loop is realized by adopting a movable end contact 11 and a static end contact 21. As shown in fig. 5, the coil M, the power source E, the resistor R, and the switch K formed by the movable terminal contact 11 and the stationary terminal contact 21 of the electromagnet are electrically connected end to end in this order, forming a series circuit. Specifically, one end of the coil M may be connected to the movable reed 1, and one end of the resistor R may be connected to the substrate 2. When the mouse button is pressed, the movable end contact 11 is contacted with the fixed end contact 21, the power supply loop of the electromagnet is conducted, the electromagnet generates attractive force on the movable reed 1, when the mouse button is sprung, the movable end contact 11 is separated from the fixed end contact 21, the power supply loop of the electromagnet is disconnected, and the magnetic force generated by the electromagnet disappears. The operating rod 3 has the advantages that the upward attractive force and the downward pressure applied to the movable reed 1 are generated simultaneously and disappear simultaneously, the parameters of the electromagnet can be reasonably selected, the movable reed 1 can always keep the initial shape, the shape of the movable reed 1 is not required to be changed by external force after the movable reed 1 is deformed, and the stability of the mouse is improved.

In the above embodiments, the movable contact spring 1 receives the attractive force from the magnetic structure 32 and the pressure from the insulating contact 31, and although the acting area and the acting position of the two forces on the movable contact spring 1 deviate, the overall size of the operation lever 3 is very small relative to the movable contact spring 1, so that the acting positions of the attractive force and the pressure on the movable contact spring 1 can be considered to be substantially coincident, and the problem that the bending of the movable contact spring 1 is aggravated due to the fact that the acting positions of the two forces are not exactly the same is avoided.

In a sixth implementation, the insulating contact 31 is a thin sheet made of an electrically insulating material, as shown in fig. 6, the insulating contact 31 covers the bottom of the magnetic structure 32, and the magnetic structure 32 may be a conventional magnet or an electromagnet, and the power supply manner and the control manner of the electromagnet may refer to the fourth implementation and the fifth implementation described above. The advantage of this operating lever 3 is that the position and the area of action of the upward attractive force and the downward pressure to which the movable contact spring 1 is subjected are highly uniform, and the attractive force is able to completely counteract the effect of the pressure.
