The rapidly growing optoelectronic industry is an application field created by combining electronics and optics. And one of the important key components is the optical transceiver module, which includes an optical transmitter (transmitter) and an optical receiver (receiver) or integrated both into an optical transceiver (transceiver), where the main function of the optical receiver It is to convert the received optical signal into an electrical signal, and the function of the transmitter is to convert the electrical signal into an optical signal for transmission. 0 In general communication products, such as hubs, it is usually set in network equipment such as hubs. There is at least one optical transceiver module for converting optical signals into electrical signals. Generally, the optical transceiver modules or components installed in the computer room are prone to accumulate pollutants such as dust. Therefore, after the optical fiber is removed from the transceiver module, if it is not properly protected, it will be polluted by dust or other impurities, causing the module Component is damaged. The traditional method is to use a set of covers. After the optical fiber is removed, the cover is inserted to block the opening of the optical transceiver module. However, the method of using the cover to prevent dust is easy to be negligent or accidental, such as forgetting to insert the cover back to the opening of the optical transceiver module, or losing the cover, which causes inconvenience to the information personnel or users in use and maintenance. . Therefore, 200533976 needs an improved optical transceiver module to solve the inconvenience of the conventional dust-proof technology. [Summary of the Invention] Therefore, an object of the present invention is to provide an optical transceiver module with a dustproof function, to prevent dust from contaminating the optical transceiver module. Another object of the present invention is to provide a light transmitting and receiving module with a dustproof function, which can achieve the effect of automatic dustproofing when the optical transceiver module is not used. Another object of the present invention is to provide a light transmitting and receiving module with a dustproof function, so that the dustproof cover plate also has the function of removing the optical transceiver module from the stacker. According to the above object of the present invention, an optical transceiver module having a dustproof function is proposed. The optical transceiver module with a dustproof function includes a module case, an -i-th plate, and a first springback member. The module housing has a first opening, the first cover plate is pivotally connected to the module housing, and the first springback member has a first end and a second end, the first end is lightly pressed against the module housing, and the first The two ends meet against the first cover plate to provide a force to cause the first cover plate to rebound to cover the first opening of the module housing to achieve a dust-proof function. According to a preferred embodiment of the present invention, the module housing includes an iron casing and a structural base. The optical transceiver module further includes a steering mechanism and an ejection slider, and the module housing further includes a driving member. Slide on the casing. The steering mechanism is, for example, a reverse mechanism, which is simultaneously coupled to the driving member and the ejection slider, and the first cover is pivotally connected to the driving member. The ejection slider is restricted to move in one direction, and has an ejection slope. When the first cover is pulled in a first direction, the driving member is disengaged by 7 200533976, and the ejection slider is moved in the opposite direction by the reverse mechanism, so as to eject the abutting member on the stacker. The function can remove the optical transceiver module from the stacker when the fiber connector is removed in different counties. It can be known from the above that the application of the optical transceiver module with dustproof function of the present invention can not only effectively prevent dust particles from polluting the transceiver module, avoid damage to internal components and optical fiber connectors, and improve the service life and reliability of the device. When the module is separated, the dustproof function has the ability to start automatically. In addition, by applying the integrated transceiver module removal function of the present invention, it is possible to remove the optical transceiver module from the stacker device without first removing the fiber connector, which is quite convenient for users and reduces fiber insertion.

Preferably, the first cover plate 104 further includes a second protruding portion 104b, staggered by a predetermined distance from the first protruding portion 10 乜, so as to facilitate a user with a larger hand shape to lift the first cover plate. The first springback member 106 uses a torsion spring and cooperates with an elastic sheet 丨 2. The elastic sheet 112 is fixed on the module housing 102 to fix the first cover when the first cover plate is opened at a pre-clamping angle A. Plate 1 〇4. Utilizing the characteristics of the elastic sheet 丨 丨 2, when the first cover 104 is opened more than a predetermined angle a, the elastic sheet 112 exerts a force on one of the positioning portions 11 () of the first cover 104 and resists the first spring member 106. Apply force and fix the first cover plate 104. When the opening angle of the first cover plate 104 is smaller than the predetermined angle A, the positioning portion 110 of the first cover plate 104 is released from the force of the elastic piece 112, and is automatically springed back to the first opening 108a by the action of the first springback member 106. The predetermined angle A is determined by the design of the elastic piece 112 and the positioning portion 110 of the first cover 104. Referring to FIG. 3 at the same time, it shows a schematic diagram of the connection between the optical fiber connector and the optical transceiver module in a preferred embodiment of the present invention. When inserting the optical fiber connector 160 into the optical transceiver module, turn the first cover 104 to make the first cover 104 separate from the 9th 200533976 opening 108a. When the rotation exceeds a predetermined angle of eight, the elastic sheet 112 places the first cover The plate 104 is pushed upward to prevent the first cover plate 104 from springing back to the first opening 108a. At this time, the optical fiber connector 160 is directly inserted into the first opening 108 and the place. To remove the optical fiber connector 160 from the optical transceiver module, first press the first cover 104, and at this time, the exit portion 162 of the optical fiber connector 160 will be pressed, so in addition to the optical fiber connector 160 exiting the first opening i〇8a In addition, the opening angle of the first cover 104 is also smaller than the predetermined angle A, so that the elastic sheet 12 no longer fixes the first cover 104, and the first cover 104 springs back to the first opening 108a to cover The first opening 108a achieves an automatic dustproof effect. Refer to Figures 4A and 4B at the same time. Fig. 4A shows a schematic diagram of the second cover plate in a preferred embodiment of the optical transceiver module according to the present invention.

The second resilient member 146 is coupled to the second cover plate 144 and the module case 102, respectively, and is configured to cover the second opening 108b on the module case 102. In this embodiment, the optical transceiver module uses two second cover plates 144, and the first springback member 146 uses a twist, which is located on the module housing 102 and has a first elastic section 146a and a second elasticity. Segment 146b is coupled to each cover plate 144 'and fixes a female-second cover plate 144 in the sliding groove 148 of the module housing 102 to cover the second opening on the module housing 102. 200533976 • 108b. The planes of the second openings referred to here are perpendicular to each other. The plane of 108 is connected to the first opening 108a. The optical fiber connector 160 has a _ ridge; 7 ^ 丄 ^ connector bevel 164, when the optical fiber connector 160 is inserted into the first open music port 108a of the optical transceiver module, the connector bevel 164 resists the force of the first rebound member 146 and pushes the flute away from the first cymbal 144. When the optical fiber connector 164 is removed from the opening of the younger brother, the first spring member 146 is no longer resisted by the connector bevel 164, and the spleen 筮 — # — pushes the first ridge plate W4 back to In situ, covers the second opening 108b to achieve automatic dustproof effect. Preferably, the second cover plate 144 further has a second cover plate inclined surface 166, the normal direction of which is parallel to the normal direction of the joint inclined surface 164, so that the joint inclined surface 164 pushes the second cover plate 144 more smoothly.

Each receiving slot 262 is provided with an abutting member 264, such as an elastic piece. When a plurality of optical transceiver modules are assembled in the stacker 260 at the same time, the abutment piece 264 is used to block the tenon 266, so that the optical transceiver module is fixed in the stacker 260. Referring also to FIG. 5B, a schematic diagram of a reverse mechanism in another preferred embodiment of the optical transceiver module according to the present invention is shown. The optical transceiver module further includes a steering mechanism and an ejection slider 270, and the module housing 202 further includes a driving member 21, which slides on the module housing 202. In this embodiment, the steering mechanism uses a reverse mechanism 240, which is simultaneously coupled to the driving member 210 and the ejection slider 200533976 270 'the first cover plate 204 is restricted to move in one direction, and: the moving member 210' The sliding block 270 is formed on the table 1 with an inclined surface 272. In the first direction, 280 forks are displaced in response to interlocking movements, and the drive member 21 and the side through the reverse mechanism 240 are used to move the ejector slider 27 in the opposite direction through the reverse 2--plate 204. Push the stacking number 1xb ^ and 260 on the top piece 264 away. In the present embodiment, the direction of the first brother 280 means 筮 pa 〇Λ〇 ^ + You know the normal direction of the first opening 208. Refer to Figure 6 at the same time, and check the schematic diagram of the components when removing the optical transceiver module when the sun is not yet activated. The reverse mechanism is not shown in the figure. 240. In this embodiment, the reverse mechanism 240 includes a rotating rod 246, a first bump 212, and a second bump 214. The first bump 212 is used to push and pull the rotating rod 246, and the first bump 214 is used to drive the ejection slider η. . The rotation lever 246 is pole-connected to the module housing 202, and the contact point is the rotation center 256 in the figure, and has a first lever arm 242 and a second lever arm 244. The first: lever arm 242 and the second lever arm 244 have a first sliding slot and a first sliding slot 254, respectively. The first bump 212 is connected and fixed to the driving member 21 and is restricted from moving in the first chute 252. The second bump 214 is connected and fixed to the ejection slider 270, and is restricted to move in the second sliding groove 254. The above description is only a case of a preferred embodiment. The second bump 214 can also be located on the second lever arm 244 'and the second sliding slot 254 is opened on the ejection slider 270, which has the same effect. All are included in the spirit and scope of the present invention. When inserting the optical fiber connector 290 into the first opening 208, only the first cover plate 204 needs to be rotated, and then the optical fiber connector 290 is inserted into the first opening 208. When the optical fiber connector 290 is removed, the first cover plate 204 is automatically rebounded by the first springback member 206 to achieve automatic dust protection. 12 200533976 Same reference No. 7 B1 'It shows the schematic diagram of the components when the function of removing the optical transceiver module is started.' The figure clearly shows that the reverse mechanism undergoes a rotation, and the first bump 212 and the second bump 214 are in the first A sliding groove 252 and a second sliding groove 254 slide, and the ejection slider 27 also moves. ^ In the state where the fiber connector 290 is still inserted in the first opening 208, 2 remove the optical transceiver module from the stacker finely, just pull the first cover 204 in the first direction 280, At this time, the driving member 210 moves accordingly. The first bumps 2 丨 2 on the driving member 210 start to move relative to each other in the first sliding groove 252, and then drive the rotating lever to rotate. Due to the rotation of the rotating lever, the second lever arm 254 will press the second bump 214, so that the second bump 214 moves relatively in the second chute 254. It will also drive the ejector slider 27. The direction 28 ° is displaced in the opposite direction. When the ejection inclined surface 272 on the ejection slider 270 touches and presses the abutment member 264, the abutment member 264 is offset, and the tenon 266 is no longer blocked. At this time, the optical transceiver module is removed from the placement slot. 262, to achieve the purpose of removing the optical transceiver module. As can be seen from the foregoing preferred embodiments of the present invention, the application of the present invention has the following advantages. The optical transceiver module with dustproof function of the present invention not only achieves the function of automatically starting the dustproof function when not in use, but also can be matched with the elastic sheet to achieve the effect of positioning the dustproof cover. The dust cover is equipped with a reverse mechanism and a slider ejection design. It also integrates the dust protection function and the optical transceiver module removal / plug-in function, and the fiber connector is removed from the optical transceiver module and the optical transceiver. The removal of modules from the stacker is independent of each other. The conventional method of removing the optical transceiver module by pulling the handle is that when the optical transceiver module is to be removed, because the fiber connector is blocked, the handle cannot be pulled directly when the fiber connector is inserted, and the 13 200533976 The fiber optic transceiver is removed from the optical transceiver module, which is very inconvenient. By using the present invention, the optical transceiver module can be removed from the stacker without removing the optical fiber connector first, and the pollution of the optical fiber and the optical transceiver module and the wear of the plugging mechanism can be reduced. Therefore, the integration of the transceiver module removal function of the present invention is really one of the major advances in this field. … Although the present invention has been disclosed as above in a preferred embodiment, # is not intended to be used by anyone who is enthusiastic about this skill, without departing from the spirit and scope of the present invention, it can be modified and retouched, so The protection scope of the present invention shall be determined by the scope of the attached patent application.
