Description

Technical Field

[0001] This invention relates to an optical module, belonging to the field of optical module technology. Background Technology

[0002] The function of an optical module is to convert electrical signals into optical signals at the transmitting end, transmit them through optical fiber, and then convert the optical signals back into electrical signals at the receiving end. An optical module is a device that performs photoelectric and electro-optical conversion.

[0003] Patent CN107966771B discloses a module anti-disengagement structure, belonging to the field of optical communication devices, specifically involving a self-sinking unlocking anti-disengagement structure for SFP+ modules. This invention patent provides an unlocking and anti-disengagement structure for SFP+ optical communication modules, applicable to coaxial device packages of optical modules, such as TOSA & ROSA PCBAs. The module structure mainly includes a PCB positioning package structure, a device positioning package structure, and an unlocking and anti-disengagement mechanism. The unlocking mechanism employs a sliding oblique pressure principle; rotating the pull ring causes the rotating shaft to push the brake block to slide horizontally, causing the oblique pressure protrusion to sink, thus unlocking. The top cover and base restrict the rotation range of the rotating protrusion; the pull ring is controlled to rotate within the range of 0–90°, conforming to the protocol requirements of current mainstream SFP+ optical modules. In the locked state, the side wings of the protrusion design press against the jumper wire to prevent the protrusion from mistakenly locking the module and causing it to fall off. In the unlocked state, the jumper wire has been pulled out, and the protrusion sinks freely without affecting normal unlocking.

[0004] However, the following defects still exist in the use of this optical module: When the optical module is plugged in with an optical fiber, the optical fiber passes through the pull ring, and the pull ring cannot be rotated due to the obstruction of the optical fiber. The optical module cannot be pulled out from the mounting base. As a result, when replacing the optical module, the optical fiber plugged into the original optical module must first be unplugged, then the pull ring must be rotated to pull out the original optical module, and the unplugged optical fiber must be inserted after replacing the new optical module. Since there are two insertion ports on the optical module, it is easy to misinsert when unplugging the optical fiber and plugging it back in. Summary of the Invention

[0005] This invention provides an optical module that solves the problems disclosed in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] An optical module, wherein a disassembly component and a driving component are provided on the first sidewall of the optical fiber connector at the front end of the optical module;

[0008] The detachable component is slidably connected to the first sidewall;

[0009] The driving component moves on the outside of the first sidewall, and the moving driving component drives the disassembly component to slide towards the rear end of the optical module;

[0010] When the optical module is pulled out from the mounting base, the driving component moves under the action of external force, driving the disassembly component to slide towards the rear end of the optical module, so that the disassembly component presses against the locking component of the optical module inside the mounting base.

[0011] The driving component includes a pull ring rotatably mounted on the first side wall via a rotating shaft. A pressing component is fixed on the rotating shaft, and the free end of the pressing component is rotatably connected to the end of the disassembly component away from the rear end of the optical module. The rotation of the pull ring drives the pressing component to rotate, and the rotating pressing component pushes the disassembly component to slide.

[0012] An elastic reset device is also provided between the disassembled component and the first side wall. When the disassembled component slides toward the rear end of the optical module under the action of external force, the elastic reset device retracts. When there is no external force, the elastic reset device extends to push the disassembled component to reset.

[0013] A blocking element is provided on the side of the disassembly part, and the elastic reset device is located in front of the blocking element along the sliding direction of the disassembly part under the action of external force.

[0014] The elastic reset device includes a V-shaped spring, a first arc-shaped spring, a second arc-shaped spring, and a third arc-shaped spring;

[0015] The opening of the V-shaped spring faces the disassembly part, one end of the V-shaped spring is connected to the first side wall, and the other end of the V-shaped spring abuts against the blocking part;

[0016] The first, second, and third arc-shaped springs are connected in sequence and located on the side of the V-shaped spring facing the disassembly part. The arc surfaces of the first, second, and third arc-shaped springs face the V-shaped spring. The free ends of the first and third arc-shaped springs are respectively connected to the two inclined plates on both sides of the V-shaped spring.

[0017] The first sidewall has a sliding groove that extends to the housing behind the optical fiber connector. The disassembly component is a disassembly strip that is slidably installed in the sliding groove.

[0018] A contact block is provided at the end of the slide groove on the rear housing of the optical fiber connector, and a matching bayonet is provided at the end of the disassembly strip opposite to the contact block.

[0019] The end face of the disassembly strip opposite to the contact block is chamfered.

[0020] A self-reset button is provided on the second side wall of the fiber optic connector. When the fiber optic terminal is inserted into the fiber optic connector, the bottom end of the self-reset button abuts against the card on the fiber optic terminal; when the self-reset button is pressed, the bottom end of the self-reset button presses down on the card.

[0021] The fiber optic connector has two opposing slide rails in the fiber optic terminal slot. The fiber optic terminal has a slide rail groove that matches the slide rail. When the fiber optic terminal is inserted into the fiber optic connector, the slide rail is embedded in the slide rail groove. Both slide rails have compression springs on opposite sides. The compression springs are used to push the inserted fiber optic terminal outward.

[0022] The beneficial effects achieved by this invention are as follows: 1. The driving component of this invention moves on the outside of the first sidewall, and the optical fiber will not block the driving component. Therefore, the original optical module can be directly pulled out without pulling out the optical fiber. The new module's optical fiber connection can be made by referring to the connection relationship of the optical fiber in the original optical module, and misinsertion is not possible; 2. An elastic reset device is provided between the disassembly component and the first sidewall of this invention. The disassembly component automatically resets when the driving component is not subjected to external force, eliminating the need for manual reset and saving time and effort; 3. A self-reset button is provided on the second sidewall of the optical fiber connection part of this invention. Pressing the self-reset button causes the bottom of the button to press down on the card, which can quickly pull out the optical fiber; 4. This invention is provided with a squeezing spring that provides outward pushing force to the inserted optical fiber terminal. When the card on the optical fiber terminal is pressed down, that is, when the optical fiber terminal is not locked, the optical fiber terminal can be pushed out of the optical fiber terminal slot a certain distance under the pushing force of the squeezing spring (at this distance, the optical fiber terminal will not be completely separated from the optical fiber terminal slot), quickly achieving separation of the optical fiber from the original optical module.

[0029] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0030] like Figure 1As shown, an optical module has a disassembly component and a driving component installed on the first sidewall of the optical fiber connector 2 at the front end of the optical module. The disassembly component is slidably connected to the first sidewall. The driving component moves outside the first sidewall, and the moving driving component drives the disassembly component to slide towards the rear end of the optical module. When the optical module is pulled out from the fixed seat, the driving component moves under the action of external force, driving the disassembly component to slide towards the rear end of the optical module, so that the disassembly component presses against the locking component of the fixed seat that locks the optical module.

[0031] The drive unit of the aforementioned optical module moves on the outside of the first sidewall. The optical fiber will not block the drive unit. Therefore, the original optical module can be directly unplugged without unplugging the optical fiber. The optical fiber of the new module can be connected by referring to the connection relationship of the optical fiber in the original optical module. Misinsertion should be avoided.

[0032] The overall structure of the optical module is an existing structure, including a front-end fiber optic connector 2 and a functional part 1 fixed at the rear end of the fiber optic connector 2. The fiber optic connector 2 mainly includes a docking housing and fiber optic terminal slots disposed within the docking housing. Two fiber optic terminal slots are generally configured. The functional part 1 includes a plug-in housing and a PCB board installed within the plug-in housing. Two docking heads 21 are soldered to the side of the PCB board near the fiber optic connector 2. A plug-in spring 8 is fixed to the side wall of the plug-in housing near the fiber optic connector 2. Plug-in springs 8 are generally fixed to the top, left, and right side walls to abut against the inner wall of the mounting base during insertion, thus providing a fixing function. When using the optical module, the functional part 1 is inserted into the mounting base of the device, with the fiber optic connector 2 exposed. The fiber optic terminal 3 is inserted from one end of the fiber optic terminal slot and connected to the corresponding docking head 21. The PCB board converts electrical signals into optical signals, which are then transmitted through the fiber optic connector 21. The receiving end then converts the optical signals back into electrical signals.

[0033] like Figure 2 As an embodiment of the present invention, the side wall corresponding to the card 20 after the optical fiber terminal 3 is inserted into the optical fiber connector 2 is defined as the top side wall of the optical fiber connector 2. The first side wall of the optical fiber connector 2 can be the bottom side wall of the optical fiber connector 2. A sliding groove 9 in the length direction of the optical module can be opened in the bottom side wall of the optical fiber connector 2. The sliding groove 9 extends all the way to the housing on the rear side of the optical fiber connector 2, that is, to the plug-in housing. The disassembly component is specifically a disassembly strip 7 that is slidably disposed in the sliding groove 9 and matches the sliding groove 9. Under the drive of the driving component, the disassembly strip 7 slides toward the rear end of the optical module.

[0034] A contact block 5 is fixed at the end of the slide groove 9 on the plug-in housing. It is a snap-fit ​​component. When the functional part 1 is inserted into the fixing seat of the device, the plug-in spring 8 on the plug-in housing snaps into the corresponding position of the fixing seat. At the same time, the contact block 5 also snaps into the corresponding position of the fixing seat, realizing multi-point embedding snap-fit.

[0035] The end of the disassembly strip 7 opposite to the contact block 5 has a matching slot 13, and the end face of this end is a chamfered surface 6. When the disassembly strip 7 slides to the rear end of the optical module, the chamfered surface 8 presses against the locking piece of the optical module in the fixing seat, causing the contact block 5 to separate from the locking piece, and the original optical module can be easily pulled out.

[0036] The aforementioned driving component is a part that provides a driving force to the disassembly bar 7 under the action of external force. There are many such structures, such as a lever, but for easier driving and less effort, as an embodiment of the present invention, such as... Figure 3 As shown, the driving component may include a pull ring 4 rotatably mounted on the bottom sidewall of the fiber optic connector 2 via a rotating shaft 10. A limiting collar 12 is fitted on the rotating shaft 10 of the pull ring 4, so that the pull ring 4 can only rotate outside the bottom sidewall of the fiber optic connector 2 and cannot be flipped to the top sidewall of the fiber optic connector 2. A pressing component 11 is fixed on the rotating shaft 10. The pressing component 11 is a pressing support plate, specifically a pressing support plate fixed to the part of the rotating shaft 10 that passes through the slide groove 9. The free end of the pressing support plate is rotatably connected to the end of the disassembly strip 7 away from the rear end of the optical module. The rotation of the pull ring 4 drives the pressing support plate to rotate, and the rotating pressing support plate pushes the disassembly strip 7 to slide.

[0037] The forward and backward sliding of the disassembly strip 7 is entirely driven by the pull ring 4. To save time and effort, as an embodiment of the present invention, as follows... Figure 4 As shown, an elastic reset device is provided between the disassembly strip 7 and the bottom side wall of the optical fiber connection part 2. When the disassembly strip 7 slides towards the rear end of the optical module under the action of external force, the elastic reset device retracts. When there is no external force, the elastic reset device extends to push the disassembly strip 7 to reset. That is, the disassembly strip 7 is automatically reset when the driving component is not subjected to external force, without the need for manual reset by personnel.

[0038] To cooperate with the elastic reset device, a blocking member 14 is fixed on the side of the disassembly strip 7, specifically a linkage compression strip. Along the sliding direction of the disassembly strip 7 under external force, the elastic reset device is located in front of the blocking member 14, specifically including a V-shaped spring 15, a first arc-shaped spring 16, a second arc-shaped spring 17, and a third arc-shaped spring 18. The opening of the V-shaped spring 15 faces the disassembly strip 7, one end of the V-shaped spring 15 is connected to the first side wall, and the other end of the V-shaped spring 15 abuts against the blocking member 14. The first arc-shaped spring 16, the second arc-shaped spring 17, and the third arc-shaped spring 18 are connected in sequence and located on the side of the V-shaped spring 15 facing the disassembly strip 7. The arc surfaces of the first arc-shaped spring 16, the second arc-shaped spring 17, and the third arc-shaped spring 18 face the V-shaped spring 15. The free ends of the first arc-shaped spring 16 and the third arc-shaped spring 18 are respectively connected to the two inclined plates on both sides of the V-shaped spring 15.

[0039] The elastic reset device can be integrally formed by stamping mold. When the disassembly bar 7 slides to the rear end, the blocking member 14 squeezes the V-shaped spring 15. The bent section in the middle of the V-shaped spring 15 bends. As the V-shaped spring 15 is squeezed, the corresponding first arc spring 16, second arc spring 17 and third arc spring 18 will also be squeezed. The second arc spring 17 in the middle will also bend. When there is no external force, the bent spring will spring back, and under the action of the springback force, it will push the disassembly bar 7 to reset.

[0040] When the fiber optic terminal 3 is pulled out of the fiber optic terminal slot of the fiber optic connector 2, the card 20 on the fiber optic terminal 3 needs to be pressed. Since the card 20 is small, pressing it is not very user-friendly. As an embodiment of the present invention, a self-reset button 19 is provided on the second side wall of the fiber optic connector 2. Specifically, the self-reset button 19 is provided on the top side wall of the fiber optic connector 2, and the bottom end of the self-reset button 19 abuts against the card 20 on the fiber optic terminal 3. When the self-reset button 19 is pressed, the bottom end of the self-reset button 19 presses down on the card 20.

[0041] The fiber optic connector 2 typically has two fiber optic terminal slots, therefore two self-reset buttons 19 can be installed, with each self-reset button 19 corresponding to one fiber optic terminal 3. However, to remove all fibers at once, such as... Figure 5 As shown, a self-reset button 19 is installed, including a pressing part 22 and two abutting parts 23. Two fiber optic terminal slots are fixed side by side. There is a cavity between the top of the two fiber optic terminal slots and the docking housing. A bracket is fixed in the cavity. The two abutting parts 23 are slidably mounted on the bracket, and the bottom ends of the two abutting parts 23 can extend into the corresponding fiber optic terminal slots. The top ends of the two abutting parts 23 are respectively connected to the two sides of the bottom end of the pressing part 22. A compression spring 24 is fixed between the middle of the bottom end of the pressing part 22 and the bracket. The top end of the pressing part 22 extends out of the docking housing. When the pressing part 22 is pressed down, the two abutting parts 23 slide downwards, and the bottom ends of the two abutting parts 23 extend into the corresponding fiber optic terminal slots, thereby pressing down the card 20, causing the fiber optic terminal 3 to disengage from the fiber optic terminal slot component, allowing the fiber to be quickly pulled out.

[0042] To further accelerate fiber extraction, as one embodiment of the present invention, see [reference needed]. Figure 6Two opposing slide rails 25 are fixed inside the fiber optic terminal slot of the fiber optic connector 2. The fiber optic terminal 3 has a slide rail groove that matches the slide rail 25. When the fiber optic terminal 3 is inserted into the fiber optic connector 2, the slide rail 25 is embedded in the slide rail groove. Both slide rails 25 are fixed with compression springs 26 on opposite sides. The compression springs 26 are wedge-shaped springs. When the fiber optic terminal 3 is inserted into the fiber optic connector 2, the slide rail groove will press the wedge-shaped springs. The wedge-shaped springs will exert an inclined force on the slide rail groove (this force can be specifically decomposed into a force perpendicular to the slide rail groove and an outward pushing force). When the snap-fit ​​structure is disengaged, under the action of the outward pushing force, the fiber optic terminal 3 can be pushed out of the fiber optic terminal slot a certain distance (at this distance, the fiber optic terminal 3 will not be completely separated from the fiber optic terminal slot), quickly realizing the separation of the fiber optic cable from the original optical module.

[0043] The process of replacing the optical module based on this invention is as follows:

[0044] When the optical module needs to be replaced, rotate the pull ring 4 to drive the disassembly strip 7 to slide. The chamfered pressing will separate the contact block 5 from the connector. Pull the original optical module out of the mounting base. The pull ring 4 will reset under the action of the elastic reset device. Press down the pressing part 22 to disengage the optical fiber terminal 3 from the optical fiber terminal slot. The optical fiber terminal 3 will pop out of the optical fiber terminal slot a distance under the action of the wedge-shaped spring. Referring to the connection relationship of the optical fiber in the original optical module, insert the optical fiber into the new optical module. Finally, insert the new optical module into the mounting base. The whole replacement process is time-saving and labor-saving, and it is not easy to misinsert.

[0045] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
