Description

Technical Field

[0001] This application relates to the field of optical communication, and more particularly to an optical module and an optical communication device. Background Technology

[0002] Optical modules are very important optoelectronic signal interface devices in optical fiber communication.

[0003] A traditional optical module has one end serving as an optical interface connected to an external optical fiber, and the other end as an electrical interface connected to an external communication device. The optical module can convert optical signals to electrical signals. A traditional optical module consists of three parts: the front end, the middle end, and the back end. The front end includes a pull ring assembly for locking and unlocking the module on the device and the optical interface, with the optical interface facing the front end. The middle end includes functional components such as a laser chip, a receiver chip, and multiplexing and / or splitter components. The back end includes the electrical interface for interconnecting electrical signals with the device. The pull ring assembly at the front end is the operational point for plugging and unplugging the optical module from the device, and is exposed on the outside of the device panel after plugging and unplugging.

[0004] In communication interconnection systems, the accuracy requirements for optical signal interconnection are far higher than those for electrical signal interconnection. However, in the traditional process of inserting and removing optical modules, the electrical interface is connected first, while the optical interface, which has higher accuracy requirements, is connected in a secondary operation. Furthermore, the optical interface is fixed and cannot be adjusted, which often results in insufficient coupling accuracy between the optical interface and the device. Summary of the Invention

[0005] In view of this, embodiments of this application aim to provide an optical module and an optical communication device to solve the problem of optical interface insertion and removal accuracy.

[0006] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0007] The optical module includes: a housing assembly, an optical interface assembly, an electrical interface, a light source, a circuit board, and a pull ring;

[0008] The electrical interface is electrically connected to the circuit board, and the electrical interface is configured to provide power to the light source.

[0009] The light source is coupled to the optical interface component;

[0010] The pull ring is disposed at one end of the housing assembly, and the optical interface assembly is floatingly disposed at the end of the housing assembly away from the pull ring.

[0011] Furthermore, the optical interface assembly includes a housing that extends from front to back, an elastic structure disposed within the housing, and a ferrule, wherein the housing is fixed to the end of the housing assembly away from the pull ring;

[0012] The insert can compress the elastic structure to achieve elastic floating relative to the housing.

[0013] Furthermore, the optical interface assembly includes a rear seat and a base;

[0014] The rear seat is detachably disposed at the rear end of the housing, and the base is disposed at one end of the insert near the elastic structure. The two ends of the elastic structure are respectively connected to the rear seat and the base in contact.

[0015] Furthermore, the housing includes a first inner cavity, a second inner cavity, and a step disposed within the housing;

[0016] The insert includes a front end, a rear end, and a guide structure. The rear end is disposed in the second inner cavity and abuts against the step. The front end passes through the first inner cavity and protrudes from the end face of the second inner cavity away from the step. The guide structure is used to assist the front end in insertion and guidance.

[0017] Furthermore, the electrical interface is located at the end of the housing assembly away from the pull ring.

[0018] Furthermore, the electrical interface is located at one end of the housing assembly near the pull ring.

[0019] Furthermore, the electrical interface is a gold finger integrally formed at one end of the circuit board; or,

[0020] The electrical interface is a pin, which is fixedly disposed inside the housing assembly and connected to the circuit board via a flexible, electrically conductive connection.

[0021] Furthermore, the electrical interface includes a fixed base and a floating component. The fixed base is fixed relative to the circuit board, and the floating component is movably disposed on the fixed base. The floating component is flexibly electrically connected to the circuit board, and the floating component can float relative to the circuit board. The floating component is used to supply power to the light source.

[0022] Furthermore, the electrical interface includes an elastic element, the floating element is inserted into the fixed base, the elastic element is arranged between the floating element and the fixed base, and the end face of the floating element is retractable relative to the fixed base.

[0023] An optical communication device for the aforementioned optical module includes an optical connector and an electrical connection portion; the optical connector is coupled to the optical interface assembly; and the electrical connection portion is detachably connected to the electrical interface.

[0024] Furthermore, the optical communication device includes a retainer cage, on which a retainer groove is formed to cooperate with the brake pad.

[0025] Furthermore, the optical communication device includes a socket, which includes an optical socket cavity and an electrical socket cavity arranged side by side. The optical connector is inserted into the optical socket cavity to connect with the optical interface assembly. The electrical connection part is a metal spring, which is disposed in the electrical socket cavity to be inserted into the electrical interface.

[0026] The optical module and optical communication device of this application embodiment are configured with a housing assembly, an optical interface assembly, an electrical interface, a light source, a circuit board, and a pull ring. The pull ring is located at one end of the housing assembly, and the optical interface assembly is located at the end of the housing assembly away from the pull ring. This allows the optical interface assembly located at the end of the housing assembly away from the pull ring to immediately connect with the optical communication device, thereby avoiding the impact of secondary insertion and removal on the optical signal coupling accuracy of the optical interface assembly. The floating configuration of the optical interface assembly allows the accuracy error caused by multiple insertions when the optical module is plugged into the optical communication device to be released by the floating of the optical interface assembly itself, thereby achieving optimal coupling between the optical interface assembly and the optical connector, ultimately resulting in high coupling accuracy.

[0048] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of this application and should not be regarded as undue limitations on this application.

[0049] In the description of the embodiments in this application, the orientations or positional relationships of "up", "down", "left", "right", "front", and "rear" are based on the appendix. Figure 1The orientations or positional relationships shown are intended only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0050] like Figures 1 to 20 As shown, an optical module 100, used in an optical communication device, includes: a housing assembly 1, an optical interface assembly 2, an electrical interface 3, a light source 4, a circuit board 5, and a pull ring 7. The light source 4 may be a semiconductor laser.

[0051] The housing assembly 1 includes a lower housing 12 and an upper housing 11 covering the lower housing 12. The lower housing 12 and the upper housing 11 form a receiving cavity (not shown) with at least one open end, which is used to accommodate other components. After assembly, the circuit board 5 can be fixedly installed within the receiving cavity. The outer side of the housing assembly 1 can be plugged into external optical fibers, optical communication devices, etc., to realize the photoelectric conversion and signal transmission / reception functions of the optical module.

[0052] The electrical interface 3 is electrically connected to the circuit board 5. It should be understood that the electrical connection here can refer to the fact that the electrical interface 3 and the circuit board 5 are connected by copper foil, wires, or metal contact to achieve the transmission of electrical energy or electrical signals between them.

[0053] The light source 4 is typically mounted on the circuit board 5, and the electrical interface 3 is configured to supply power to the light source 4. That is, the electrical interface 3 supplies power to the light source 4 through the circuit board 5 to generate an optical signal. As those skilled in the art will know, in the field of optical device technology, an optical module has an independent package, and the circuit board 5 integrates the necessary components for completing the photoelectric signal conversion.

[0054] For example, components such as an optical modulator (not shown), a multiplexer (not shown), and a demultiplexer (not shown) can be integrated on circuit board 5. The optical modulator is used to load electrical signals onto optical energy, thereby outputting a signal-carrying optical signal. Specifically, loading electrical signals onto optical energy to form a specific form of optical signal can change the phase, amplitude, etc., of the light. Optical signals of different wavelengths can be combined by the multiplexer to form a single optical signal. A single optical signal containing multiple wavelengths is then split into multiple single-wavelength optical signals by the demultiplexer.

[0055] The light source 4 is coupled to the optical interface component 2, which is used to output the continuous light energy emitted by the light source 4.

[0056] The pull ring 7 is located at one end of the housing assembly 1, and the optical interface assembly 2 is floatingly located at the end of the housing assembly 1 away from the pull ring 7. That is to say, the pull ring 7 serves as the operating end to facilitate the docking of the optical module 100 with the optical communication device, and the optical interface assembly 2, located at the end of the housing assembly 1 away from the pull ring 7, can dock with the optical communication device immediately, thereby avoiding the impact of secondary plugging and unplugging on the optical signal coupling accuracy of the optical interface assembly 2.

[0057] The optical interface component 2 is movably mounted on the shell component 1. At least a portion of the structure of the optical interface component 2 can float relative to the shell component 1. It should be understood that, here, "floating" means that, without detaching from the constraint of the shell component 1, at least a portion of the structure of the optical interface component 2 can extend and retract, swing left and right, or shift horizontally relative to the shell component 1 within a certain range.

[0058] Therefore, when the optical module 100 is plugged into the optical communication device, the shell assembly 1, the card cage 6 (mentioned below), and the socket 9 (mentioned below) are plugged into each other. The accuracy error caused by multiple plugging can be released by the floating of the optical interface assembly 2 itself, so that the coupling between the optical interface assembly 2 and the optical connector 82 (mentioned below) achieves the best effect and the coupling accuracy is high.

[0059] In the specific operation process, the optical module 100 is plugged into the optical communication device. The electrical interface 3 transmits the received electrical energy to the circuit board 5 and then to the light source 4 to excite the light source 4 to emit an optical signal. The optical signal is transmitted to the optical communication device through the optical interface component 2. Depending on the application scenario, the optical communication device can use the optical signal as its own signal source, or it can split off an optical fiber from itself to transmit the optical signal to other devices.

[0060] In related technologies, refer to Figure 21 The optical interface 2' is located at the first end of the housing assembly 1' near the pull ring (in a folded state, not shown), and the electrical interface 3' is located at the second end of the housing assembly 1' away from the pull ring. The second end needs to be connected to the optical communication device, and a corresponding locking mechanism needs to be set to prevent the two from loosening. The first end needs to be connected to the connector 9', and a corresponding locking mechanism needs to be set to ensure the coupling accuracy of the optical signal. Therefore, the optical modules of the relevant technologies need to be equipped with corresponding locking mechanisms for the connector 9' and the optical communication device respectively.

[0061] In this embodiment, since the optical interface component 2 is located at the end of the housing component 1 away from the pull ring 7, the optical interface component 2 is directly inserted into the optical communication device. The optical communication device and the optical module 100 are locked together by a locking mechanism to prevent them from coming loose, and the coupling accuracy of the optical signal can be ensured, thus simplifying the structure.

[0062] In one possible embodiment, the optical module includes a brake pad 71 connected to a pull ring 7. The pull ring 7 is rotatable relative to the housing assembly 1 to drive the brake pad 71 to lock with the optical communication device, thereby ensuring that the optical communication device and the optical module 100 will not become detached and ensuring the coupling accuracy of the optical signal.

[0063] One possible implementation, such as Figures 1 to 5 As shown, the optical interface assembly 2 includes a housing 21 that extends from front to back, an elastic structure 23 disposed within the housing 21, and a ferrule 25.

[0064] Along the axial direction of the housing assembly 1, the ferrule 25 can be completely disposed inside the housing 21, with the end face of the ferrule 25 flush with the front end of the housing 21; the ferrule 25 can also be partially disposed at the front end of the housing 21, that is, the end face of the ferrule 25 protrudes from the front end of the housing 21, so as to better facilitate coupling and docking with the optical connector 82 of the optical communication device.

[0065] It should be noted that, unless otherwise specified, refer to Figure 1 and Figure 2 In various embodiments of this application, the extension direction of the shell assembly 1 is axial, wherein the direction from the pull ring 7 to the optical interface assembly 2 along the axial direction is forward, and the end of the shell 21 near this direction is the front end; the direction from the optical interface assembly 2 to the pull ring 7 along the axial direction is backward, and the end of the shell 21 near this direction is the rear end.

[0066] The housing 21 is fixed to the end of the housing assembly 1 away from the pull ring 7. Specifically, a fixing groove 215 can be formed on the outer wall surface of the housing 21, and the lower housing 12 and / or upper housing 11 of the housing assembly 1 are respectively provided with positioning blocks that cooperate with the fixing groove 215 to fix the housing 21 to the housing assembly 1.

[0067] It is important to understand that the "floating" here refers to the ability of the ferrule 25 to extend and retract, swing left and right, or shift horizontally relative to the housing 21 within a certain range, without detaching from the housing 21. The ferrule 25 can compress the elastic structure 23 to achieve elastic floating relative to the housing 21. On the one hand, the fixed deviation between the housing 21 and the housing assembly 1, and the fixed deviation between the housing assembly 1 and the retainer 6, can all be corrected by the floating of the ferrule 25 itself, so that the ferrule 25 can achieve high coupling accuracy with the optical connector 82.

[0068] On the other hand, the elastic structure 23 always exerts an axial elastic force on the ferrule 25. Under this elastic force, the ferrule 25, which protrudes from the front end of the housing 21, fits tightly with the optical connector 82 of the optical communication device, so that the two can be reliably connected, thereby achieving the best optical coupling effect.

[0069] One possible implementation, such as Figures 1 to 5As shown, the optical interface assembly 2 includes a rear seat 24 and a base 22.

[0070] The rear seat 24 is detachably mounted on the rear end side of the housing 21. Figures 2 to 4 In the illustrated non-limiting embodiment, the connection method can be snap-fit, with a positioning hole 214 formed on the peripheral sidewall of the housing 21 and a corresponding locking block 242 provided on the rear seat 24. The locking block 242 can engage with the positioning hole 214 to achieve fixation. In other non-limiting embodiments, the rear seat 24 and the housing 21 can also be connected by screws or other methods.

[0071] The base 22 is located on one end of the insert 25 near the elastic structure 23. The elastic structure 23 is a spring. The two ends of the elastic structure 23 are respectively connected to the rear seat 24 and the base 22. The elastic structure 23 applies elastic force to the insert 25 through the base 23 to protect the fragile insert 25 and prevent it from breaking.

[0072] When the ferrule 25 is attached to the optical connector 82 of the optical communication device, the reaction force at the contact point can compress the elastic structure 23 of the ferrule 25 to achieve elastic floating relative to the housing 21. When the optical module 100 is inserted into the optical communication device, the accuracy error caused by multiple insertions can be released by the floating of the ferrule 25 itself, so that the coupling between the ferrule 25 and the optical connector 82 (mentioned below) achieves the best effect and the coupling accuracy is high.

[0073] One possible implementation, such as Figures 1 to 5 As shown, the housing 21 includes a first inner cavity 211, a second inner cavity 212, and a step 213 disposed within the housing 21. That is, the step 213 divides the inner cavity of the housing 21 into the first inner cavity 211 and the second inner cavity 212, with the first inner cavity 211 being smaller than the second inner cavity 212. It can be understood that the inner cavity of the housing 21 is continuous from front to back, and the step 213 serves as the annular dividing interface between the first inner cavity 211 and the second inner cavity 212.

[0074] The ferrule 25 includes a front end 251, a rear end 252, and a guide structure 253. The rear end 252 is larger than the front end 251. The ferrule 25 is inserted into the housing 21. The rear end 252 is located within the second inner cavity 212 and abuts against the step 213. The front end 251 passes through the first inner cavity 211 and protrudes from the end face of the second inner cavity 212 away from the step 213, so as to facilitate coupling and docking with the optical connector 82 of the optical communication device. The base 22 is disposed on the bottom surface of the rear end 252 away from the front end 251. The rear seat 24 is fixed to the end of the second inner cavity 212 away from the first inner cavity 211 to serve as a support for the elastic structure 23. The two ends of the elastic structure 23 are respectively connected to the rear seat 24 and the base 22 to provide a certain preload force to the ferrule 25 through the base 22.

[0075] The guide structure 253 is typically disposed on the end face of the front end portion 251. The guide structure 253 is used to guide the front end portion 251 to the optical connector 82 of the optical communication device during insertion. Typically, the guide structure 253 is a guide post or a guide hole, and the optical connector 82 is provided with a guide portion 821 corresponding to the guide structure 253.

[0076] The optical interface assembly 2 may also include an optical fiber 26. A through hole 241 is formed in the middle of the rear seat 24. One end of the optical fiber 26 is coupled to the light source 4, and the other end passes through the through hole 241 and the base 22 until it is connected to the ferrule 25. The end face of the optical fiber 26 passes forward through the rear end 252 and the front end 251 and reaches the end face of the front end 251. The front end 251 is tightly fitted with the optical connector 82 of the optical communication device to complete the coupling.

[0077] One possible implementation, such as Figures 10 to 11 As shown, the electrical interface 3 is located at the end of the housing assembly 1 furthest from the pull ring 7. Even if the electrical interface 3 and the optical interface assembly 2 are located at the same end of the housing assembly 1, during the insertion and removal of the optical module 100 from the optical communication device, the optical interface assembly 2 couples with the optical connector 82, and the electrical interface 3 connects with the corresponding electrical connection part 83, achieving optoelectronic connection in a single insertion and removal, saving the number of insertions and removals and reducing the cost of the entire optoelectronic system. Here, the optoelectronic system refers to the optical communication device, the optical module, and the corresponding auxiliary structures.

[0078] During operation, the optical module 100 is plugged into the optical communication device. The optical communication device transmits electrical energy to the electrical interface 3 through the electrical connection part 83. The electrical energy is transferred to the circuit board 5 and then to the light source 4 to excite the light source 4 to emit an optical signal. The optical signal is transmitted to the optical connector 82 of the optical communication device through the optical interface component 2, completing the photoelectric signal conversion. Depending on the application scenario, the optical communication device can use the optical signal as its own signal source, or it can branch off an optical fiber to transmit the optical signal to other devices.

[0079] exist Figures 1 to 3 ,as well as Figures 18 to 20 In the illustrated, non-limiting embodiment, the electrical interface 3 is a gold finger integrally formed on the circuit board 5, which has a simple structure and facilitates the design of circuits on the circuit board 5. The electrical connection part 83 can be a metal spring disposed in the electrical socket cavity 92 (mentioned below). While the optical interface assembly 2 and the optical connector 82 are coupled and docked, the electrical interface 3 is correspondingly inserted into the electrical socket cavity 92 and connected to the electrical connection part 83 to realize circuit connection. The gold finger can be disposed on both sides of the insert 25, or on the top and / or bottom of the insert 25, depending on the design.

[0080] exist Figures 3 to 9In the illustrated non-limiting embodiment, the electrical interface 3 is a pin with a simple structure. The electrical interface 3 is fixedly disposed within the housing assembly 1 and electrically connected to the circuit board 5 via a flexible strip 51. The electrical connection part 83 can be a female plug corresponding to the electrical interface 3. When the optical interface assembly 2 and the optical connector 82 are coupled and docked, the electrical interface 3 is inserted into the corresponding electrical connection part 83 to achieve circuit connection. When the electrical interface 3 and the electrical connection part 83 are inserted and removed, mechanical stress is generated. While maintaining the electrical connection between the two, the flexible strip 51 can eliminate the mechanical stress of the electrical interface 3 through flexible deformation, thereby preventing the mechanical stress from being transmitted to the optical interface assembly 2 through the circuit board 5 and improving the coupling accuracy between the optical interface assembly 2 and the optical connector 82.

[0081] The electrical interface 3 is a pin and is fixedly installed with the housing assembly 1. The electrical interface 3 can be designed as multiple or one. The position can be set on both sides of the core 25, or above and / or below the core 25, depending on the design.

[0082] exist Figures 13 to 17 In the illustrated non-limiting embodiment, the electrical interface 3 includes a fixed base 31 and a floating member 32. The fixed base 31 is fixed relative to the circuit board 5, and the floating member 32 is movably disposed on the fixed base 31, allowing it to float relative to the circuit board 5. Here, "floating" refers to the ability of the floating member 32 to extend and retract, swing left and right, or shift horizontally relative to the circuit board 5 within a certain range without detaching from the fixed base 31.

[0083] The optical module is plugged into the optical communication device. The floating component 32 is used to power the light source 4. The floating component 32 provides electrical energy to the light source 4 through the circuit board 5 to generate an optical signal. The mechanical stress generated by the insertion and removal of the electrical connection part 83 and the floating component 32 is released by the floating component 32 itself, thereby preventing the mechanical stress from being transmitted to the optical interface component 2 through the circuit board 5. This allows the optical interface component 2 to couple with the optical connector 82 with minimal external interference, ultimately improving the coupling accuracy of the optical interface component 2.

[0084] The optical module 100 includes a flexible strip 51. The floating member 32 is electrically connected to the circuit board 5 via the flexible strip 51. When the electrical interface 3 is inserted or removed from the electrical connection part 83, mechanical stress is generated. While maintaining the electrical connection between the two, the flexible strip 51 can eliminate the mechanical stress of the electrical interface 3 through flexible deformation, so as to prevent the mechanical stress from being transmitted to the optical interface assembly 2 through the circuit board 5, thereby improving the coupling accuracy between the optical interface assembly 2 and the optical connector 82.

[0085] Depending on the design requirements, the flexible strip 51 can be a flexible circuit board; a multi-core ribbon cable; or multiple flexible wires. It is low in cost, has stable conductivity, and can effectively eliminate the mechanical stress of the electrical interface 3 through its own deformation.

[0086] One possible implementation, such as Figures 13 to 17 As shown, the electrical interface 3 includes an elastic element 33 and a floating element 32 inserted into the fixed base 31. The elastic element 33 is arranged between the floating element 32 and the fixed base 31, and the end face of the floating element 32 is retractable relative to the fixed base 31. That is, the end face of the floating element 32 is retractable relative to the circuit board 5, thus forming a male plug. The electrical connection part 83 can be configured as a female plug as needed. The floating element 32 is inserted into the electrical connection part 83 in the form of a male and female plug to complete the connection between the two. The corresponding mechanical stress causes the floating element 32 to extend and retract back and forth, swing left and right, or shift horizontally, thereby avoiding the mechanical stress from being transmitted to the optical interface assembly 2, and ultimately improving the coupling accuracy of the optical interface assembly 2.

[0087] Specifically, such as Figure 7 As shown, the floating component 32 is a hollow cylinder with one open end. A positioning hole 311 is formed on the fixed base 31. The inner diameter of the positioning hole 311 is larger than the outer diameter of the floating component 32. The two are fitted together to form a gap C, 0.01mm≤C≤0.5mm, so that the floating component 32 can be vertically offset up and down or horizontally offset left and right according to the mechanical stress generated when it is inserted into the electrical connector 82. It can also swing left and right and up and down within the angle B with one end of the floating component 32 as the fulcrum, 1°≤B≤10°. While maintaining the electrical connection between the floating component 32 and the circuit board 5, mechanical stress is avoided from being transmitted to the optical interface assembly 2, and the coupling accuracy of the optical interface assembly 2 is ultimately improved.

[0088] One possible implementation, such as Figures 10 to 13 As shown, the electrical interface 3 is located at one end of the housing assembly 1 near the pull ring 7. Even if the electrical interface 3 and the optical interface assembly 2 are located at opposite ends of the housing assembly 1, during the insertion and removal of the optical module 100 and the optical communication device, the optical interface assembly 2 and the optical connector 82 are coupled and connected, and then the electrical interface 3 is connected to the corresponding external circuit, so that the external circuit can provide power to the electrical interface 3.

[0089] During operation, the optical module 100 is plugged into the optical communication device. External circuitry transmits electrical energy through the electrical interface 3. This energy is then transferred to the circuit board 5 and subsequently to the light source 4, exciting it to emit a light signal. The light signal is then transmitted through the optical interface assembly 2 to the optical connector 82 of the optical communication device, completing the photoelectric signal conversion. This external circuitry can be a power line separately drawn from another device to power the optical module 100, or it can be a separate power line drawn from the optical communication device. Depending on the application scenario, the optical communication device can use the light signal as its own signal source, or it can branch off an optical fiber to transmit the light signal to other devices.

[0090] This application further provides an optical communication device for use with the aforementioned optical module 100, such as... Figures 18 to 20 As shown, the optical communication device includes an optical connector 82 and an electrical connection part 83; the optical connector 82 is coupled to the optical interface assembly 2; the electrical connection part 83 is detachably connected to the electrical interface 3.

[0091] In addition, the optical communication device includes a cage 6, which has a cavity capable of accommodating an optical module and a rectangular toothed groove formed on its outer peripheral side to facilitate heat dissipation. The cage 6 has a slot 61 that cooperates with the brake pad 71. When the optical module 100 is inserted into the cage 6, the slot 61 and the brake pad 71 cooperate to lock the optical module 100 and the cage 6, thereby realizing the locking of the optical communication device and the optical module 100.

[0092] One possible implementation, such as Figure 18 , 19 and Figure 20 As shown, the optical communication device includes a socket 9 and a PCB board 200.
