Abstract
The utility model discloses a 1X 2 small-size mechanical type photoswitch, including single fiber collimator, reflection prism, speculum and two fiber collimator, wherein, single fiber collimator, two fiber collimator are located speculum one side, and reflection prism is located between single/two fiber collimator and the speculum, and reflection prism fixes and to make it reciprocate and cut into and withdraw from the actuating mechanism of light path. By adopting the structure, the up-and-down movement of the driving mechanism is utilized to drive the reflecting prism to cut in and withdraw from the light path so as to realize the switching of the light path. Meanwhile, because the single optical fiber collimator and the double optical fiber collimator are arranged in the same direction, the original input and output at two ends are changed into single-end input and output, the size of the optical switch can be greatly reduced, and the installation is convenient.
Description
Affiliated technical field
The utility model relates to a kind of 1 * 2 mechanical optical switch that optical communication system, optical tests system, optical sensor system play light path switching effect that is used for, and refers in particular to a kind of 1 * 2 mechanical optical switch of small size.
Background technology
Photoswitch is a kind of switching device, and it can be transformed into another loop or path with the signal in optical fiber, integrated circuit or other optical waveguides from a loop or path effectively.According to principle of work and material therefor, photoswitch can be divided into mechanical type and on-mechanical formula two big classes, and the utility model relates generally to mechanical optical switch, and mechanical optical switch can be divided into moving fiber and mobile optical element dual mode again.Disclose in the existing technology and a kind ofly repeated that performance is good, 1 * 2 mechanical optical switch of mobile refracting prisms (as shown in Figure 1), many shortcomings such as moving fiber poor repeatability, the rebound shake is big to the light path influence, the life-span is short, Insertion Loss is big have been avoided, but still because its input light and output light lay respectively at both sides, account for volume during installation, be difficult to reach the strict demand of modern optical communication.
Summary of the invention
The purpose of this utility model is to provide 1 * 2 mechanical optical switch that a kind of volume is little, be convenient to install.
For realizing above-mentioned purpose, the utility model adopts following structure: a kind of 1 * 2 small-sized machine formula photoswitch, comprise single fiber collimating apparatus, reflecting prism, catoptron and double-fiber collimator, described single fiber collimating apparatus, double-fiber collimator are positioned at catoptron the same side, reflecting prism between list/pair fine collimating apparatus and catoptron, and reflecting prism be fixed on it is moved up and down and the driving mechanism of incision and exit optical on.
Adopt said structure to utilize moving up and down of driving mechanism to drive reflecting prism incision and exit optical, to realize the switching of light path.Simultaneously,, can reduce the volume of photoswitch greatly, be convenient to install because be arranged so that in the same way original two ends input, the output of single fiber collimating apparatus, double-fiber collimator become single-ended input, output.

Embodiment
A kind of 1 * 2 small-sized machine formula photoswitch of the utility model, comprise single fiber collimating apparatus 4, reflecting prism 2, catoptron 3 and double-fiber collimator 1, described single fiber collimating apparatus 4, double-fiber collimator 1 are positioned at catoptron 3 the same sides, reflecting prism 2 between list/double- fiber collimator 1,4 and catoptron 3, and reflecting prism 2 be fixed on it is moved up and down and the driving mechanism 6 of incision and exit optical on.
Principle of work of the present utility model is such: light beam is from an end incident of double- fiber collimator 1, and 3 reflections are coupled into the other end output of double-fiber collimator 1 through catoptron.Move up by adding a driving mechanism 6, make the reflecting prism of fixing on it 2, make light beam pass through reflecting prism 2 and produce the reflection displacement, from 4 outputs of single fiber collimating apparatus.Be the incision and the exit optical of reflecting prism 2, beam direction is changed, thereby reach the purpose that switch switches.
