Embodiment
Please refer to Fig. 1 and Fig. 2, an embodiment provides a kind of Hall switch 100.This Hall switch 100 comprises the first housing 110, second housing 120, signal processing unit 130, Hall element 140, magnet 150, reposition element 160 and switch element 170.
The shell closed also is formed together with first housing 110 is slidably connected with the second housing 120.Signal processing unit 130, Hall element 140, magnet 150, reposition element 160 and switch element 170 are arranged in the shell that the first housing 110 and the second housing 120 formed.Signal processing unit 130 receives the signal that Hall element 140 produces and to go forward side by side row relax.Hall element 140 and magnet 150 are individually fixed on the first housing 110 and the second housing 120.One end of reposition element 160 is fixed on the first housing 110, and the other end is fixed on the second housing 120.Reposition element 160 herein resets for making the first housing 110 and the second housing 120 after change in location appears in the first housing 110 and the second housing 120.Switch element 170 is electrically connected with Hall element 140 phase, when the first housing 110 to the second housing 120 near time, Hall element 140 is close to magnet 150, and switch element 170 is converted to conducting state.
In this embodiment, the first housing 110 is provided with snap fit 112, and the second housing 120 is provided with block 122.When first housing 110 and the second housing 120 are fixed together, snap fit 112 coordinates with block 122 and prevents the first housing 110 from separating with the second housing 120.Like this, the phenomenon mutually departed from would not be there is when the first housing 110 and the second housing 120 relative sliding.The mode that snap fit 112 coordinates with block 122 is also convenient to the first housing 110 and the second housing 120 carries out assembly and disassembly.
The signal processing unit 130 of this Hall switch 100 is a pcb board being provided with Signal Processing Element, and this pcb board processes the signal that Hall element 140 produces and is passed to this Hall switch 100 outside.Signal processing unit 130, the pcb board being namely provided with Signal Processing Element is arranged between Hall element 140 and the first housing 110.Can conveniently be electrically connected with Hall element 140 phase like this.
The switch element 170 of this Hall switch 100 comprises contact 172 and copper facing pcb board 174.Contact 172 is fixed on the first housing 110, and copper facing pcb board 174 is fixed on the second housing 120.Copper facing pcb board 174 is provided with copper facing region and non-copper facing region.As shown in Figure 2, the left side of copper facing pcb board 174 is non-copper facing region, and the right is copper facing region.
When the first housing 110 and the second housing 120 close to each other time, contact 172 slides to copper facing region by non-copper facing region.Contact 172 is herein electrically connected with Hall element 140 phase, and the copper facing region on copper facing pcb board 174 can be electrically connected mutually with external power source.Hall element 140 is also electrically connected mutually with external power source.Such Hall element 140, contact 172 and copper facing pcb board 174 just can form a loop with external power source.Certainly, also power supply can be arranged in the first housing 110 and the second housing 120, namely this Hall switch also comprises the supply unit for Hall element 140 power supply herein.
The area that contact 172 contacts with copper facing pcb board 174 is comparatively large, and reliability is higher, not easily comes in contact bad phenomenon.In order to the replacing making contact 172 contact with copper facing pcb board 174, the quantity of contact 172 is two herein.Be sliding contact between contact 172 and copper facing pcb board 174 in addition, the deformation that contact 172 produces is less, and the useful life of contact 172 can be made so longer.
In this embodiment, the reposition element 160 of this Hall switch 100 is back-moving spring.One end of back-moving spring is fixed on the first housing 110, and the other end is fixed on the second housing 120.
The end of the second housing 120 of this Hall switch 100 is provided with to be convenient to point the bend placed.That is, the second housing 120 has the profile of a trigger shape.Like this, operated by personnel can be facilitated in use.
In addition, the meta that this Hall switch 100 also comprises restriction first housing 110 mutually close with the second housing 120 is locked.At this Hall switch 100 for devices such as electric tools, and electric tool is not when using state, meta lock can by this Hall switch 100 under lock and key, makes the first housing 110 and the second housing 120 can not be too close, thus prevent the electric tool work of this Hall switch 100 of accident use.
During use, this Hall switch 100 can be installed on the devices such as electric tool.During initial condition, the first housing 110 and the second housing 120 are separated from each other to maximum distance.Now, magnet 150 and Hall element 140 lie farthest away, contact 172 contacts with the non-copper facing region of copper facing pcb board 174.Therefore circuit not conducting, this Hall switch 100 no power.
User presses the second housing 120, and make the second housing 120 close to the first housing 110, magnet 150 is close to Hall element 140.Because this Hall switch is pinned by meta lock, contact 172 still has a segment distance with the copper facing region on copper facing pcb board 174, and this is the upper electrical distance of safety.Now, Hall element 140 not yet detects changes of magnetic field, and the performance loop of electric tool can not conducting, and electric tool does not work.
Solution removes meta lock, and the second housing 120 continues to the first housing 110 close, and magnet 150 is close to Hall element 140.Contact 172 contacts with the copper facing region on copper facing pcb board 174, and Hall element 140 is started working and changes of magnetic field detected.Hall element 140 passes the signal along to signal processing unit 130, and signal processing unit 130 pairs of signals process and pass, and electric tool makes electric tool enter operating state according to the signal that signal processing unit 130 transmits.
Second housing 120 continues to the first housing 110 close, and magnet 150 is close to Hall element 140.Contact 172 slides on the copper facing region of copper facing pcb board 174, and Hall element 140 detects changes of magnetic field.The signal that Hall element 140 transmits by signal processing unit 130 carries out processing and the corresponding module transferred on electric tool, the signal adjustment electric tool rotating speed etc. that electric tool transmits according to signal processing unit 130.Thus play the effect of speed governing.When the second housing 120 and the first housing 110 lean on nearest time, electric tool will enter full-speed operation state.
When user does not press the second housing 120, the second housing 120 gets back to initial position by under the drive of reposition element 160, i.e. the position of the first housing 110 and the second housing 120 lie farthest away.Now electric tool quits work.
This Hall switch 100 just achieves the effect controlling electric tool work like this.This Hall switch 100 can control the switch of electric tool, and can control the rotating speed of electric tool.
Signal processing unit 130, Hall element 140, magnet 150, reposition element 160 and switch element 170 are arranged in the shell that the first housing 110 and the second housing 120 surround by this Hall switch 100, during such assembling, this Hall switch 100 just can carry out overall package, therefore this Hall switch 100 assembling and change can be very convenient.The shell that first housing 110 and the second housing 120 surround simultaneously can protect the inner member of this Hall switch 100, makes this Hall switch have the advantage of good dustproof effect.Therefore, this Hall switch 100 has assembling and the advantage changing convenient and good dustproof effect.
The above embodiment only have expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
