Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of communication equipment, in particular to an anti-falling optical module. Background Art
[0002] The optical module is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic devices include transmitting and receiving parts. The function of the optical module is to convert electrical signals into optical signals at the transmitting end. After being transmitted through optical fibers, the receiving end converts the optical signals into electrical signals. The two ends of the optical module are ports for connecting optical fiber lines and connecting to devices through gold finger ends. In actual use, the optical fiber line ports may become loose due to long-term extraction and pressure from the weight of the optical fiber line, and the optical fiber line may fall off. The traditional gold finger end is directly plugged into the device, so the weight of the entire optical module is borne by the gold finger part. Combined with the influence of the weight of the optical fiber at the other end of the optical module, the overall installation form of the optical module is slightly tilted. Long-term use may easily cause the gold finger part to wear and fall off. Therefore, there is room for improvement in how to ensure the stability of the installation and connection of the optical module. Utility Model Content
[0003] The utility model aims to provide an anti-falling optical module to solve the above problems existing in the prior art.
[0004] The technical problem to be solved by the utility model is to improve stability and prevent wear and falling off.
[0005] The technical solution of the utility model to solve the above technical problems is as follows:
[0006] An anti-falling optical module comprises a shell and a cover body, wherein two baffles are arranged on the right side of the outer wall of the shell, a module mainboard is arranged in the shell, two opposite sides of the two baffles are fixedly connected with positioning buckles, the two positioning buckles are plugged with the module mainboard, an optical fiber connector is arranged at one end of the module mainboard away from the baffle, a mounting platform is fixedly installed on the top of the optical fiber connector, an adjustment component is movably installed inside the mounting platform, a calibration plate is fixedly installed on the bottom of the adjustment component, the optical fiber connector is provided with two optical fiber interfaces, two square limit grooves adapted to the optical fiber interfaces are provided inside the calibration plate, and the two positioning buckles are both "C" shaped.
[0007] The beneficial effect of the utility model is that the gold finger end of the module mainboard is arranged in the groove of the positioning buckle, and the gold finger can be stabilized by relying on the C-shaped structural characteristics of the positioning buckle, avoiding the problem of loosening and slipping of the gold finger end due to wear.
[0008] The left and right side walls of the cover are provided with bolt plates, and the top of the shell is provided with threaded grooves accordingly. The cover can be threadedly connected to the shell by bolts, which is convenient for maintenance and replacement of the module mainboard inside the shell. The main part of the module mainboard is covered by the shell and the cover to block dust, and the gold finger end can rely on the baffle and positioning buckle to block dust to avoid poor contact caused by dust. The non-fully-enclosed design of the gold finger end also has better heat dissipation capability to prevent heat accumulation.
[0009] A square limit groove is provided in the alignment plate to match the shape of the optical fiber interface on the optical fiber connector. The optical fiber line will preferentially pass through the square limit groove and then be connected with the optical fiber connector. Therefore, the optical fiber line can be positioned by the alignment plate. When the alignment plate is fixed, the optical fiber line cannot loosen, thereby ensuring the stability of the optical fiber connection. The positioning rod can pass through the positioning platform in sequence and extend to be connected to the circular hole groove of the connecting rod to form a limit. When the connecting rod is limited, the alignment plate will also be limited. Therefore, when the optical fiber line passes through the alignment plate and is connected with the optical fiber connector, the line itself will be limited by the alignment plate. When the connecting rod drives the alignment plate to rise, the top of the inner wall of the square limit groove will support the bottom of the optical fiber line, thereby avoiding the problem of natural sinking of the optical fiber line due to no load-bearing, resulting in wear and loosening of the optical fiber connector.
[0010] On the basis of the above technical solution, the present invention can also be improved as follows.
[0011] Furthermore, a positioning platform is fixedly installed on the top of the mounting table, a positioning rod is inserted into the interior of the positioning platform, the adjustment component includes a connecting rod, a circular hole groove matching the positioning rod is opened inside the connecting rod, an empty groove is opened inside the mounting table, and the connecting rod is inserted into the empty groove, and the alignment plate is fixedly connected to the bottom of the connecting rod.
[0012] The beneficial effect of adopting the above further solution is that the connecting rod is used to drive the alignment plate to rise and fall, and the positioning rod is used to position the connecting rod.
[0013] Furthermore, the adjustment assembly also includes an anti-slip ring, and the anti-slip ring is fixedly installed on the outside of the connecting rod. The anti-slip ring is annular and larger than the inner diameter of the empty groove to prevent the connecting rod from falling off.
[0014] The beneficial effect of adopting the above further solution is that the empty groove inside the mounting platform is used to provide lifting space for the connecting rod, and the anti-slip ring can prevent the connecting rod from detaching from the mounting platform.
[0015] Furthermore, the adjustment assembly also includes a handle, and the top of the connecting rod is provided with a handle.
[0016] The beneficial effect of adopting the above further solution is that the handle is used to lift the connecting rod up and down.
[0017] Furthermore, the exteriors of the two positioning buckles are both covered with an insulating rubber sheath.
[0018] The beneficial effect of adopting the above further solution is that the positioning buckle covered by the insulating rubber sleeve layer can increase the friction force to clamp the gold finger and improve stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0027] like Figure 1-5 As shown, embodiment 1 of the present invention is an anti-falling optical module, comprising a shell body 1 and a cover body 2, two baffles 3 are arranged on the right side of the outer wall of the shell body 1, a module main board 5 is arranged in the shell body 1, two positioning buckles 4 are fixedly connected to the opposite sides of the two baffles 3, the two positioning buckles 4 are plugged with the module main board 5, an optical fiber connector 6 is arranged at the end of the module main board 5 away from the baffle 3, a mounting platform 7 is fixedly installed on the top of the optical fiber connector 6, an adjustment component 9 is movably installed inside the mounting platform 7, a calibration plate 10 is fixedly installed on the bottom of the adjustment component 9, the optical fiber connector 6 is provided with two optical fiber interfaces, and two square limit grooves adapted to the optical fiber interfaces are provided inside the calibration plate 10, and the two positioning buckles 4 are both "C" shaped.
