Abstract
A suspension-typed coil-driving reflecting mirror device used for optical switches consists of the levers, a mobile reflecting mirror, a suction device of the mobile reflecting mirror and an electromagnetic device. The levers are arranged on a pivot point; the mobile reflecting mirror is arranged on the lever at one side of the pivot point; the electromagnetic device consists of a fixing magnetic element and a motion magnetic element; the motion magnetic element is arranged on the lever at the other side of the pivot point and the fixing magnetic element is arranged at the position which is fixed relative to the pivot point. The gap is maintained between the fixing magnetic element and the motion magnetic element. The suction device of the mobile reflecting mirror is arranged at the position which is fixed relative to the pivot point and is arranged at one side of the pivot point where the mobile reflecting mirror is arranged. As the suspension-type coil is adopted and the electromagnetic force is utilized to push the lever and the reflecting mirror at the other end of the lever, the non-touch drive without friction can be realized and the number of on-off times of the optical switch can achieve one hundred million, thus greatly enhancing the reliability of the mechanical optical switch and simultaneously shortening the on-off time by almost a half and the volume of the mechanical optical switch is smaller.
Description
Technical field:
The utility model relates to a kind of photoelectronic device, relates in particular to a kind of optical switch components, particularly a kind of floated coil drive reflector apparatus that is used for photoswitch.
Background technology:
Photoswitch is a kind of one or more selectable transmit pories that have, and can mutually transfer the light signal in the optical transmission pathway or the device of logical operation, can realize optical cross connect, wavelength selection, Route Selection, self-healed protection, go up function such as download.Photoswitch commonly used at present has mechanical optical switch, electrooptical switching, magneto-optic shutter, MENS photoswitch, ink-jet bubble thermo-optical switch, liquid crystal optical switch, holographic optical switch, acoustooptic switch, liquid grating photoswitch etc.
In the world research and time of application machine formula photoswitch long, the photoswitch of the type is the most practical, the most ripe and most widely used at present photoswitch.Its advantage is: insert that loss is lower, isolation is high, be subjected to polarization state of light and wavelength affects is less, be not subjected to restriction, the price comparison of the data layout that system adopts cheap, its weak point be grow switching time (being generally 8ms), life-span fall short of (generally the switch number of times is 1,000 ten thousand times), volume ratio is bigger.However, the switching time of mechanical optical switch and life-span can have been satisfied the demand of general optical communication network, therefore still have irreplaceable effect in current optical-fiber network.In addition, in other non-Communication ray network system not high to the switch rate requirement, in optical tests system, optical sensor system, its cost performance is higher, and the photoswitch of other type can't be compared with it especially.Mechanical optical switch can be subdivided into again: moving fiber type (comprising mobile sleeve pipe, mobile collimating apparatus) and mobile optical element type (comprising mobile mirror, mobile prism) two big classes." moving-member " of mechanical optical switch generally all with miniature relay etc., promotes with the direct way of contact, thereby reaches the purpose of conversion light path.This type of drive has limited the dwindling of speed, serviceable life and volume of mechanical optical switch.
As shown in Figure 1, the ultimate principle of mechanical optical switch now is described with 1 * 2 mobile mirror photoswitch, among Fig. 1 the 20,21, the 22nd, the parallel standard fiber collimating apparatus that is placed on sustained height, 10,11, the 12nd, the plane mirror that corresponding collimating apparatus axis with each becomes 45 degree to place, 12 is movable part.When 12 were in a high position, 12 and 10,11 were in sustained height.At this moment from the light of 20 optical fiber collimators input,, export through 22 collimating apparatuss by 12 reflections again through 10 reflection directives 12.At this moment OUT2 is in " opening " attitude, and OUT1 then is in " pass " attitude.When driving mechanism moves to low level with 12, after 10 reflections, cross top, ground directive 11 by the light of 20 inputs, and export through 21 optical fiber collimators by 11 reflections, at this moment OUT2 is " pass " attitude, OUT1 is in " opening " attitude.Move 12 position by driving mechanism, reach the purpose of switching-over light path.Here adopt relay to do driving mechanism usually.Because there is the swing reforming phenomena in relay in handoff procedure, also have the friction in the physical construction, influences the serviceable life of product and the raising of speed, has reduced reliability of products simultaneously.
Summary of the invention:
Technical problem to be solved in the utility model is: photoswitch is widely used in a plurality of fields of optical signal transmission, lacks shortcomings such as (1,000 ten thousand times), switching speed slow (10ms) and volume be bigger than normal but the existing conventional mechanical optical switch exists the life-span.The utility model provides a kind of floated coil drive reflector apparatus that is used for photoswitch for the technical scheme that above-mentioned technical matters adopted that solves in the prior art, the described this floated coil drive reflector apparatus of photoswitch that is used for is by lever, mobile mirror, mobile mirror suction device and calutron constitute, wherein, described lever is arranged on the fulcrum, described mobile mirror is arranged on the lever of described fulcrum one side, described calutron is made of a stationary magnetic element and a motion magnetic element, described motion magnetic element is arranged on the lever of described fulcrum opposite side, described stationary magnetic element is arranged on the position of fixing with respect to described fulcrum, maintain the gap between described stationary magnetic element and the motion magnetic element, described mobile mirror suction device is arranged on the position of fixing with respect to described fulcrum, and is mobile mirror one side at described fulcrum; Concrete, described fulcrum can be made of an axle; Described mobile mirror suction device adopts magnet; Described motion magnetic element is a solenoid, and described solenoid is arranged on the described lever, and described stationary magnetic element is a permanent magnet, and described permanent magnet is arranged on the position of fixing with respect to described fulcrum; Further, be set with wire winding pole on the described lever, described solenoid twines and is arranged on the described wire winding pole, and described wire winding pole is an iron core.Described permanent magnet has a cavity in shape, and the internal diameter of described cavity makes described solenoid can enter into the cavity of described permanent magnet, but mutual contact friction can not take place greater than the external diameter of described solenoid; Further, described stationary magnetic element also can adopt solenoid, and described solenoid is arranged on the position of fixing with respect to described fulcrum, and simultaneously, described motion magnetic element adopts permanent magnet, and described permanent magnet is arranged on the described lever; Further again, the quantity of described motion magnetic element can not be only limited to one, can adopt two solenoids.
The utility model and prior art contrast, and effect is positive and tangible.A kind of floated coil drive reflector apparatus that is used for photoswitch of the utility model, owing to adopted floated coil, utilize electromagnetic force to promote the catoptron of the lever and the lever other end, so can realize nothing friction, noncontact drives, the switch number of times of photoswitch can reach 100,000,000 times, than the mechanical optical switch life-span has been improved an order of magnitude in the market, thereby the reliability of mechanical optical switch is improved greatly, simultaneously switching time is less than 5ms, and nearly half and volume are littler than having shortened the switching time of most of photoswitches in the market.
