Description

Technical Field

[0001] The invention relates to the technical field of optical line terminal equipment of a passive optical network system, in particular to an SFP optical transceiver integrated module. Background Art

[0002] SFP (Small Form-factor Pluggable Transceiver) is a small pluggable optical transceiver module, which is mainly used to realize the conversion between optical signals and electrical signals in optical communication systems.

[0003] The prior art has the following deficiencies: the “SFP optical transceiver integrated module” with the publication number CN201820018U in the prior art “includes: a module upper cover; a module side panel sheet metal; an MPO connector; a hot-swappable unlocking device for the optical module; a module base; a PCB circuit board, on which a PLC planar optical waveguide splitter is provided, and the first end of the splitter is provided with at least one optical transmitting device for transmitting multiple downstream optical signals, and its pigtail is optically coupled with the second end of the PLC planar optical waveguide splitter through an optical fiber array, and at least one MCR mode coupled optical receiving device for receiving multiple upstream optical signals is also provided at the second end of the splitter, and the two devices are respectively connected to the PCB circuit board through a flexible circuit board”.

[0004] The above structure reduces the maintenance cost of system equipment by expanding the functions of 4 conventional OLT modules on the OLT slot, but the structure does not make improvements to the interface of the optical fiber connection end. The commonly used SFP optical transceiver modules are divided into two types: the optical fiber interface end has a manually disassembled protection structure and the optical fiber interface end does not contain any protection structure. The optical fiber interface without a protection structure will have residual attachments that are difficult to clean during use due to its concave structural characteristics, which will cause the optical fiber to be in a poor connection state over time, and the manually disassembled protection structure needs to be disassembled and processed separately before and after the use of the SFP optical transceiver module, which is inconvenient. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides an SFP optical transceiver integrated module, which solves the existing problems of contaminants adhering to the optical fiber interface and the need for manual disassembly and assembly of the protective structure.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an SFP optical transceiver integrated module, comprising a main frame, an upper protective shell, a base and a control panel, the upper protective shell is arranged at the upper end of the main frame, the base is arranged at the lower end of the main frame, the control panel is arranged at the upper end of the upper protective shell, a circuit board is arranged at the upper end of the main frame, and an optical transmitting component and an optical receiving component are arranged on the side of the circuit board.

[0007] A driving end adjusting wheel is arranged at the side end of the main frame, a linkage end synchronizing wheel is arranged at the upper end surface of the upper end of the main frame away from the driving end adjusting wheel, and a linkage end adjusting wheel is arranged at the outer end of the other side of the main frame.

[0008] The main frame also includes a side bracket, a motor, and an optical fiber interface. The side bracket is provided with two groups and is integrally die-cast with the main frame. The motor is fixedly installed at the inner end of the side bracket close to the driving end adjusting wheel. The optical fiber interface is provided with two groups and is opened at the front end of the main frame.

[0009] In some embodiments, the driving end adjusting wheel also includes a shielding frame, a driving end synchronous wheel, a synchronous belt and a protective plug, the shielding frame is fixedly connected to the outer end surface of the driving end adjusting wheel, and the driving end synchronous wheel is fixedly connected to the upper end of the driving end adjusting wheel.

[0010] In some of the embodiments, the synchronous belt is sleeved on the periphery of the synchronous wheel at the driving end, and the protective plug is adhered to the end surface of the shielding frame close to the main frame by brushing glue.

[0011] In some embodiments, the linkage end synchronous wheel also includes a changing gear, a linkage gear and a connecting shaft, and the linkage end synchronous wheel is movably connected to the upper end of the main frame through a shaft body at the bottom.

[0012] In some embodiments, the direction-changing gear is fixedly connected to the upper end of the synchronous wheel at the linkage end, the tooth groove of the linkage gear is meshed with the direction-changing gear, and a movable connection relationship is established with the upper end of the connecting shaft, and the connecting shaft is movably connected to the middle part of the adjusting wheel at the linkage end.

[0013] In some of the embodiments, a bottom of the driving end adjusting wheel is in active connection with a motor, and the motor is embedded in the end side bracket.

[0014] In some of the embodiments, two groups of shielding frames are provided, and fixed connections are established with the outer sides of the driving end adjusting wheel and the linkage end adjusting wheel respectively, and the rotation range of the shielding frames is fixed to 180°.

[0015] Compared with the prior art, the present invention provides an SFP optical transceiver integrated module:

[0016] An SFP optical transceiver integrated module is provided with a driving end adjustment wheel, a driving end synchronous wheel, a synchronous belt, a linkage end adjustment wheel, a direction-changing gear and a linkage gear. When the device is used, the operator checks the optical transceiver data and controls the operation of the motor through the control panel. First, the motor is controlled to start, and the motor controls the driving end synchronous wheel to rotate through the driving end adjustment wheel. When the driving end synchronous wheel rotates, the linkage end synchronous wheel is driven to rotate simultaneously through the synchronous belt, and the direction-changing gear on the upper end of the linkage end synchronous wheel rotates in the same direction. At this time, the linkage gear meshed with its tooth groove is driven, and the linkage end adjustment wheel is driven to rotate through the connecting shaft. At this time, the driving end adjustment wheel and the linkage end adjustment wheel rotate in opposite directions at the same time, and drive the shielding frame and the protective plug on both sides to rotate, until the shielding frame rotates 180 degrees and the protective plug is detached from the optical fiber interface, and then the optical fiber is inserted, and the photoelectric signal conversion is performed through the optical transmitting component, the optical receiving component and the circuit board;

[0017] The above settings and processes can make the device have the following beneficial effects:

[0018] By dividing the two sides of the main frame into a driving end and a linkage end, and transmitting through the driving end synchronous wheel and the linkage end synchronous wheel, the structure can automatically drive the shielding frame and the protective plug. Compared with the traditional optical transceiver module, this structure can ensure the cleanliness of the optical fiber interface when not in use and prevent attachments from entering the interior of the optical fiber interface. The fully automatically controlled shielding frame is more convenient to use than the manually disassembled and assembled protective structure, and the optical fiber interface can be inserted with one hand.

[0032] A driving end adjusting wheel 8 is arranged at the side end of the main frame 1 , a linkage end synchronizing wheel 9 is arranged at the upper end surface of the upper end of the main frame 1 away from the driving end adjusting wheel 8 , and a linkage end adjusting wheel 10 is arranged at the outer end of the other side of the main frame 1 .

[0033] The main frame 1 also includes a side bracket 101, a motor 102, and an optical fiber interface 103. The side bracket 101 is provided with two groups and is integrally die-cast with the main frame 1. The motor 102 is fixedly installed at the inner end of the side bracket 101 close to the driving end adjusting wheel 8. The optical fiber interface 103 is provided with two groups and is opened at the front end of the main frame 1.

[0034] In this embodiment, the driving end adjusting wheel 8 also includes a shielding frame 801, a driving end synchronous wheel 802, a synchronous belt 803 and a protective plug 804. The shielding frame 801 is fixedly connected to the outer end face of the driving end adjusting wheel 8, and the driving end synchronous wheel 802 is fixedly connected to the upper end of the driving end adjusting wheel 8; the synchronous belt 803 is sleeved on the periphery of the driving end synchronous wheel 802, and the protective plug 804 is glued to the end face of the shielding frame 801 close to the main frame 1 by brushing glue.

[0035] Specifically, Figure 1 Figure 2 and Figure 7 As shown, the motor 102 drives the driving end adjusting wheel 8 to rotate, and then the driving end adjusting wheel 8 drives the linkage end synchronous wheel 9 on the other side through the driving end synchronous wheel 802 and the synchronous belt 803 on the top.

[0036] In this embodiment, the linkage end synchronization wheel 9 also includes a changing gear 901, a linkage gear 902 and a connecting shaft 903.

First, the motor 102 is controlled to start, and the motor 102 controls the driving end synchronous wheel 802 to rotate through the driving end adjustment wheel 8. When the driving end synchronous wheel 802 rotates, it drives the linkage end synchronous wheel 9 to rotate at the same time through the synchronous belt 803, and the direction-changing gear 901 at the upper end of the linkage end synchronous wheel 9 rotates in the same direction. At this time, the linkage gear 902 meshing with its tooth groove is driven, and drives the linkage gear 902 through the connecting shaft 903. The linkage end adjusting wheel 10 rotates, and at this time, the driving end adjusting wheel 8 and the linkage end adjusting wheel 10 rotate in the opposite direction at the same time, and drive the shielding frame 801 and the protective plug 804 on both sides to rotate, until the shielding frame 801 rotates 180° and the protective plug 804 is disengaged from the optical fiber interface 103, and then the optical fiber is inserted, and the photoelectric signal conversion is performed through the optical transmitting component 6, the optical receiving component 7, and the circuit board 5.
