In order to solve the above-mentioned technical problem, the present embodiment provides a kind of multichannel optical switches.Illustrating the utility model reality
Before applying example, the working principle and structure feature of existing multichannel optical switch are first introduced, to help to understand the utility model reality
Apply the relevant programme in example.
In the prior art, input terminal is moved to corresponding output end by driving part by photoswitch, and it is logical to complete light
Road switching, therefore there are used in mechanical optical switch and the documents by mentioning in background technique through lens or electricity
Machine completes the conducting switching of output end.
The lens of use realize optical path switching, higher to the shape and machining accuracy of lens, cause lens production process difficult
Spend that larger, processing cost is high；Optical path switching is realized using motor driven input terminal, rotating arm is influenced by input terminal optical cable, is rotated
Limited angle, there are output optical fibre collimators, and blind angle is connected, and more demanding to the control precision of motor and control direction.
For this purpose, providing a kind of multichannel optical switch in the present embodiment, motor is equally used to complete input terminal and output
Switching between end, is different from the prior art, and multichannel optical switch structure provided in this embodiment uses unique structure feature
Conducting is realized to the light beam between input terminal and output end.Concrete scheme is as follows:
Referring to Figure 1-3, multichannel optical switch provided in this embodiment includes array disk 10, optical fiber collimator, reflection rib
Mirror 20 and driving assembly 30.
Referring to Figure 1-2, wherein optical fiber collimator includes an input collimator 40 and several output collimators 50,
And it is assembled on array disk 10.Wherein input collimator 40 is coaxially fixed on the center point of array disk 10, output collimator 50
It is isometrical to be arranged on array disk 10 then to input collimator 40 as the center of circle, and input collimator 40 and output collimator 50 is equal
The same side of array disk 10 is set.The quantity of output collimator 50 can be two or more, according to output collimator
50 quantity, the multichannel optical switch structure be made into 1x2,1x3 ... 1x32 or the optical switch construction in higher amount channel.
Fig. 3 is referred to, in the present embodiment, array disk 10 is in the form of annular discs, has been formed uniformly U-shaped in the periphery of array disk 10
Locating slot, output collimator 50 are fixed in U-shaped locating slot by glue.It should be noted that although adopting in the present embodiment
With U-shaped locating slot, but the locating slot can voluntarily process forming V-shape, rectangular or other shapes according to processing request and difficulty of processing
Locating slot, as long as can realize that the installation to output collimator 50 is fixed in locating slot.
Wherein, reflecting prism 20 is then right against optical fiber collimator, and the light beam for enabling input collimator 40 input is by reflexing to
Output collimator 50.
Fig. 4 is referred to, specifically, reflecting prism 20 is in be parallel to the radial strip of array disk 10, and reflecting prism 20
Length is equal with the radius of circle that output collimator 50 is formed.It is respectively formed with inclined-plane 21 at the both ends of reflecting prism 20, is enabled anti-
The cross sectional shape for penetrating prism 20 is trapezoidal.On reflecting prism 20, one of inclined-plane 21 back to input collimator 40, and with it is defeated
Enter the coaxial arrangement of collimator 40.
Wherein, driving assembly 30 is stepper motor, and one end of reflecting prism 20 is fixed at the shaft of stepper motor, and tiltedly
Face 21 enables reflection prismatic rotate the circle that the circle to be formed is formed with output collimator 50 and is arranged coaxially back to input collimator 40.
As a kind of preferred technical solution, the angle between inclined-plane 21 and the side of reflecting prism 20 is 45 °, enables reflection
The isosceles trapezoid that the cross sectional shape of prism 20 is 45 ° in base angle.
In the turn on process on two-beam road, input collimator 40 input light beam penetrate reflecting prism 20, with input
Collimator 40 reflects at corresponding inclined-plane 21, since the angle between inclined-plane 21 and the side of reflecting prism 20 is 45 °, makes
The incidence angle that must be inputted between light beam and inclined-plane 21 is 45 °, and the light beam after reflection can be along the length direction of reflecting prism 20
It propagates, and the second secondary reflection occurs at another inclined-plane 21, similarly, in the second secondary reflection, incidence angle is similarly light beam
45°.To sum up, if incident beam projects light by the reflecting prism 20 of above structure perpendicular to the length direction of reflecting prism 20
The direction of beam and the direction of incident beam are parallel, and difference is that two light beams are located at two inclined-planes 21.
In order to be coated with reflecting layer on the inclined-plane of reflecting prism 20 21 as a kind of preferred technical solution.
According to the design feature and reflection characteristic of above-mentioned reflecting prism 20, multichannel optical switch provided in this embodiment,
Input collimator 40 is arranged in parallel with output collimator 50, i.e., the input light beam with output collimator 50 of input collimator 40 is defeated
Light beam is parallel out.According to above-mentioned input collimator 40, output collimator 50 and reflecting prism 20, the light beam of collimator 40 is inputted
After reflection by reflecting prism 20, it can be exported always from by the other end of reflecting prism 20, and enter output collimator
50。
Due to parallel between input light and output light, there is no angles, so that energy between reflecting prism 20 and array disk 10
Enough arbitrarily to move in beam direction, i.e., reflecting prism 20 uses both ends inclined-plane 21 for the structure of 45° angle, can make reflecting prism
Spacing between 20 and array disk 10 can accomplish 1mm minimum distance, reduce loss caused by various errors.
Multichannel optical switch provided in this embodiment is provided with input collimator and output collimator on array disk, leads to
The optical path realization conducting that both ends have bevelled reflecting prism to input collimator and output collimator is crossed, driving assembly pair is passed through
Reflecting prism is rotated, and then realizes the switching of output collimator；Input collimator and output collimator are in the same side, closely
Distance is lost small；Output collimator be collimator annular array, it is compact-sized, output end can large capacity extension, annular array can
To be made into N channel (N < 360) high reliablity.
Embodiments described above does not constitute the restriction to the technical solution protection scope.It is any in above-mentioned implementation
Made modifications, equivalent substitutions and improvements etc., should be included in the protection model of the technical solution within the spirit and principle of mode
Within enclosing.
