In operation, the relay can be switched on/off via voltage control to swing the cantilever beam; and the high reflecting mirror moves upward/downward to regulate incident light through the double-fiber collimator. The utility model has the advantages of convenient installation, good sealing performance, high precision and low manufacturing cost.
Description
Technical field
The utility model relates to a kind of photoswitch, particularly a kind of 2 * 2 photoswitches.
Background technology
The optical communication field of 21st century has entered into brand-new full optical communication epoch.In the optical communication network, photoswitch all has a wide range of applications in light path protection and recovery, optical fiber cross connection (0XC), optical add/drop multiplexer (OADM), wavelength-division multiplex (WDM).Photoswitch is the optical passive component of outbalance, can carry out the switching of break-make to light signal in the optical communication network system.The photoswitch broad market prospect is one of the most potential optical passive component.
2 * 2 photoswitches of existing market generally all are to form with glue technology encapsulation, not only install inconveniently, and sealing, precision are low, and cost is also higher relatively, does not have the very strong market competitiveness.
The utility model content
It is a kind of easy for installation that the purpose of this utility model is to provide, good seal performance, and 2 * 2 photoswitches of precision height, low cost of manufacture are to solve the weak point that existing light opens the light and exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of 2 * 2 photoswitches comprise:
One shell has the cavity that puts relay in the enclosure, has automatically controlled pin bores in the bottom of cavity;
Two are fixedly mounted on the weldering bridge on the shell two side;
Two are welded on the two fine collimating apparatus in the bridge;
One is installed in the relay in the shell cavity, and the automatically controlled pin of described relay is drawn from the automatically controlled pin bores on the shell, and a semi-girder is installed on described relay, and the front end of semi-girder is fixed a high reflective mirror;
One cover and be fixed in the cover plate of shell cavity accent portion.
For fixed relay better, make it have more stability, in the bottom design of shell cavity projection is arranged.
In order to ensure the sealing and the precision of 2 * 2 photoswitches, at the accent portion periphery design groove of cavity.Described cover plate and groove are fitted, and the slit between cover plate and groove seals with scolding tin.
2 * 2 photoswitches of the present utility model come the pilot relay adhesive by control voltage, drive the semi-girder swing, and then it is last or following to drive high reflective mirror by semi-girder, to control the optical path change of the light that enters from two fine collimating apparatuss, play the effect of light path selection.
Owing to adopted design proposal as above, the utlity model has easy for installationly, the sealing performance is good, precision height, advantage of low manufacturing cost.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of the utility model 2 * 2 photoswitches.
Fig. 2 is the structural representation of the described shell of the utility model 2 * 2 photoswitches.
Fig. 3 is the structural representation of the described relay of the utility model 2 * 2 photoswitches.
Fig. 4 is the structural representation of the described two fine collimating apparatuss of the utility model 2 * 2 photoswitches.
Embodiment
Referring to Fig. 1, a kind of 2 * 2 photoswitches comprise shell 1, relay 2, a butt welding bridge 3, a pair of two fine collimating apparatuss 4; Whole casing 1 adopts the filled gold made, and expansion coefficient is little, and resistance to compression is shockproof, and scolding tin is adsorbed on it, strengthens the fastness of photoswitch.In shell 1, have the cavity 11 that puts relay 2 and have in order to fix the weldering bridge opening of a butt welding bridge 3, have automatically controlled pin bores 12 in the bottom of cavity 11 in the two side of shell 1; For fixed relay 2 better, make relay 2 have more stability, in the bottom design of cavity 11 projection 13 is arranged.In order to ensure the sealing of 2 * 2 photoswitches, at the accent portion periphery design groove 14 of cavity 11.When snapping bridge opening, should guarantee that the weldering bridge opening on shell 1 two side is positioned on the same axis.
As can be seen from Figure 1, weldering bridge 3 is the cylinder type member, adopts in the two weldering bridge openings of mode welded and installed on shell 1 of welding, during welding, should adopt unit clamp, guarantees can be positioned on the same axis after 3 welding of two weldering bridges.
A pair of two fine collimating apparatus 4 usefulness scolding tin are fixed in the weldering bridge 3, for two fine collimating apparatus 4 all directions can both firmly be fixed in the weldering bridge 3 well, on the barrel of weldering bridge 3, have four circular holes 31 up and down, scolding tin can be poured into by these four circular holes 31, two fine collimating apparatuss 4 firmly are fixed in the weldering bridge 3.
Relay 2 usefulness glue are fixed in the cavity 11 of shell 1, automatically controlled pin 21 on it is drawn from the automatically controlled pin bores 12 of shell 1 bottom, control voltage is by automatically controlled pin 21 inputs, 22 swings of control semi-girder, semi-girder 22 is installed on the relay 2, and the front end of semi-girder 22 is fixed a high reflective mirror 23 with glue, in the time of semi-girder 22 swings, drive high reflective mirror 23 and move up and down, thereby control is played the effect of switch from the light that two fine collimating apparatuss 4 enter.Accent portion at cavity 11 also has a cover plate 5, and cover plate 5 is fitted with groove 14, and the slit that cover plate 5 and groove are 14 seals with scolding tin, improves sealing and precision.Design can fixed relay in the projection 13 of the bottom of cavity 11, makes it have more stability.
Certainly,, do not spend performing creative labour, on the basis of the foregoing description, can do multiple variation, can realize the purpose of this utility model equally for one of ordinary skill in the art.But this variation obviously should be in the protection domain of claims of the present utility model.
