× N, M × N etc. are a variety of, and they have different purposes in different occasions.What is be most widely used at present is still 1 × 2 and 2 × 2 machines
Tool formula photoswitch.Light can be directly coupled to output end by mechanical optical switch by moving fiber, be switched using prism, speculum
Light path, output end is directly sent to or reflexes to by light.Wherein, 2 × 2 mechanical optical switch, is entering end and is going out end respectively to have two light
Fibre, can complete two kinds of connection status, parallel connection and interconnection.
The application environment of existing mechanical optical switch is usually out of doors so that its building block is easily squeezed by external force
It is pressed into and damages its internal part, not only greatly reduce the performance of optical transport, while also can greatly shortens the life-span of device.
Thus the encapsulation of the mechanical optical switch of application under such circumstances is extremely important.
Utility model content
Therefore, for it is above-mentioned the problem of, the utility model proposes a kind of housing packaged type mechanical optical switch, to existing
The structure of mechanical optical switch is improved, and strengthens its anti-pressure ability, improves the life-span of device, it is ensured that lower photoswitch is used for a long time
Optical transport performance.
In order to solve the above-mentioned technical problem, the utility model is the technical scheme adopted is that a kind of housing packaged type is mechanical
Relay and prism are provided with formula photoswitch, including housing, housing, two relative side walls of housing are correspondingly provided with earhole, two
The end of individual collimater is fixed in earhole, and the both sides extension from earhole to outside housing；The central axis position of two collimaters
In on same straight line, and the axis extended line of collimater both passes through prism；Prism is between two collimaters, and and relay
Output end be fixedly connected, prism is moved up and down in the presence of relay, so realize prism into and out collimater it
Between light path；Glass tube, the outer package of glass tube are arranged with outside accommodating cavity of the collimater provided with receiving optical fiber, collimater
There is protective metal shell formation metal ear；The one end of metal ear is fixed on housing, and the other end offers through hole, so that light
Fibre is stretched out away by the through hole.By setting up metal ear, the glass tube in collimater can be further protected, glass is prevented
Pipe and optical fiber are lost, thus can strengthen the anti-pressure ability of photoswitch.
As a kind of preferred scheme, the length of the metal ear vertically is more than the length of glass tube, radially
Width is more than the diameter of glass tube, namely the optical fiber that the fully wrapped around glass tube of metal ear and a part stretch out；More enter one
Step, the metal ear is sheathed on outside glass tube, and its end is fixed by viscose glue and is attached on housing.
In order to further improve the anti-pressure ability of metal ear, as a kind of preferred scheme, the metal ear it is vertical
Section is class elliptical shape, and such elliptical shape includes arc left side wall, straight upper side wall, the right side wall of arc and straight
Lower wall.
Further, the collimater is double-fiber collimator.
The utility model compared with prior art, is encapsulated, cocoa is further by such scheme by setting up metal ear
The glass tube in collimater is protected, prevents glass tube and optical fiber from losing, so as to increase the compressive resistance of switch.In addition, ellipse using class
The metal ear of toroidal, increases its anti-pressure ability, can avoid causing compressing to the glass tube of its inside after the extruding of metal ear,
Further protect glass tube and optical fiber.When making, metal ear can be fabricated separately, the metal ear is then set in standard
Outside straight device, the both sides of switch case are then pasted respectively, it is easy to make and realized, with good practicality.
Brief description of the drawings
Fig. 1 is the overall schematic of mechanical optical switch of the present utility model；
Fig. 2 is side view of the present utility model.
