Abstract
The present invention discloses a voice coil motor for optical communication device products. The motor comprises a pedestal, a permanent magnetism cell group, a motion carrying base, a conductive coil, a set of cylinder springs and a top cover. The permanent magnetism cell group is fixed on the pedestal to form a magnetic field generation device; the conductive coil is fixed on the motion carrying base to form a linear mobile device; a set of guiding rods on the pedestal, a set of through holes on the motion carrying base and the set of cylinder springs form a resetting mechanism and limit the mobile device to perform lateral movement; and the end of the column on the motion carrying base is provided with a through hole and configured to bond an optics function part so as to realize corresponding optics functions. The voice coil motor provided by the invention has long linear movement distance and small size, and is convenient to be integrated in the light-regulated products such as a light attenuator, a light switch and the like to be taken as the actuating parts of the light-regulated products.
Description
Technical field
The present invention relates to a kind of voice coil motor, a kind of voice coil motor for optic communication device product.
Background technology
Scalable light product such as optical attenuator and photoswitch is very important fiber optic passive device in optical-fiber network, plays very important effect in fiber optic communication systems, is to realize the intelligentized critical component of optical-fiber network.Optical attenuator and light type of opening the light includes mechanical type, waveguide type, liquid crystal type, micromechanics etc..Wherein waveguide type and liquid crystal type are due to reasons such as match materials, are also not widely used at a lot of application scenarios；Traditional mechanical formula product is the most progressively withdrawn from the market due to its volume reason and is replaced with the product of micromechanics type.
Current micromechanics type product mainly has baffle arrangement and micromilTor device.The former technological design is complicated, relatively costly during small lot；Simultaneously because of the reason such as technology and material, the displacement that typically can reach is all between some tens of pm, it is impossible to meets the one hundred micron of needs blocked completely of light beam number after the conventional collimated lens of single-mode fiber, thus limits being widely used of it.The latter is the most affected by environment, and the requirement to encapsulation is high.
Summary of the invention
It is an object of the invention to provide a kind of voice coil motor, it has in longer rectilinear movement distance, small volume and the scalable optic communication product such as be easy to be integrated in optical attenuator, light opens the light the actuated components as them.
A kind of voice coil motor for optic communication device product provided according to the present invention, it includes that base, permanent magnet unit group, motion carry seat, conductive coil, cylindrical spring and top cover.It is characterized in that permanent magnet unit group is fixed on described base composition field generator for magnetic；Conductive coil is fixed on motion load seat and constitutes linear shifter；One group of guide bar on base, motion carry the through hole on seat and cylindrical spring group composition linear shifter resets and limits linear shifter and makees shifted laterally；The square column end that motion carries on seat has a through hole for bonding optical function parts to realize corresponding optical function.

Detailed description of the invention
Below in conjunction with the accompanying drawings, a kind of voice coil motor being applicable to optic communication device product of the present invention is described in further detail.In the accompanying drawings, identical reference represents identical parts, feature or structure.
As it is shown in figure 1, a kind of voice coil motor being applicable to optic communication device product of the present invention includes that base 100, permanent magnet unit group 200, motion carry seat 300, conductive coil 400, cylindrical spring group 500 and top cover 600.Its structure is: described permanent magnet unit group 200 is fixed on described base 100 composition field generator for magnetic；Described conductive coil is fixed on motion load seat and constitutes linear shifter, and after conductive coil 400 energising, linear shifter is for linear motion under field generator for magnetic effect.
Such as Fig. 2, the number of assembling steps of a kind of voice coil motor being applicable to optic communication device product of the present invention is: the relevant position that permanent magnet unit group 200 is fixed on base 100 constitutes field generator for magnetic；Conductive coil 400 is arranged on motion and carries composition linear shifter on seat 300；4 guide bars (101,102,103 and 104, such as 3) on base 100 are carried 4 through holes (311,312,313 and 314, such as Fig. 4) on seat 300 by motion；Again four cylindrical springs of cylindrical spring group 500 are inserted on guide bar 101,102,103 and 104 respectively；Finally top cover is installed.
4 guide bars on described base 100, motion carry 4 through holes on seat 300 and cylindrical spring group 500 forms resetting-mechanism and limits mobile device and make shifted laterally.
Described motion carries seat 300 separately a rectangle column 320, its end has a through hole 330(such as Fig. 4), realize corresponding optical function such as wavelength regulation, light intensity attenuation or light path switching etc. for pasting the optical function parts such as optical filter, light barrier, reflecting mirror, wedge such as.
Although combining accompanying drawing above to describe in detail structure and the number of assembling steps of the present invention, but foregoing description nonrestrictive.Those skilled in the art can carry out suitable change to this voice coil motor on the basis of above disclosure, such as, change some concrete part shape or quantity, but this also should fall into protection scope of the present invention.
