[0049] This invention provides an optical transceiver for fiber optic composite ground wire in power distribution networks, which solves the technical problem of poor overall heat dissipation in existing optical transceivers for fiber optic composite ground wire in power distribution networks during operation.

[0050] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0051] For easier understanding, please refer to Figures 1 to 8 The present invention provides an optical transceiver for a power distribution network using an optical fiber composite ground wire. The optical transceiver for a power distribution network uses an optical fiber composite ground wire to communicate with the power distribution network. It includes a dustproof unit, a top heat dissipation unit, an optical transceiver body, and a bottom heat dissipation unit.

[0052] The dustproof unit includes a top cover 1, two sets of plug-in components and a cooling fan 8, all of which are fixedly installed inside the top of the top cover 1;

[0053] The top heat dissipation unit is located on the top of the optical transceiver body 5, and includes a horizontal plate 6, two sets of connecting components and two sets of supporting components. The two ends of the horizontal plate 6 are connected to the supporting components through the connecting components.

[0054] The dustproof unit is embedded in the horizontal plate 6 via a plug-in assembly;

[0055] The cooling fan 8 is used to respond to the heat dissipation signal, deliver airflow to the top of the optical transceiver body 5, and deliver airflow to the bottom of the optical transceiver body 5 through the cavity in the horizontal plate 6, the connecting component and the support component;

[0056] The bottom heat dissipation unit and all supporting components are connected to the bottom of the optical transceiver body 5 to guide airflow and dissipate heat from the bottom of the optical transceiver body.

[0057] The heat dissipation signal is used to control the cooling fan to start and deliver airflow.

[0058] In this embodiment of the invention, the dustproof unit includes a top cover 1, two sets of plug-in components, and a cooling fan 8. Both the plug-in components and the cooling fan 8 are fixedly connected to the top inner surface of the top cover 1. The top heat dissipation unit includes a horizontal plate 6, two sets of connecting components, and two sets of supporting components. The horizontal plate 6 is located on the top outer surface of the optical transceiver body 5, and both ends of the horizontal plate 6 are connected to the supporting components via connecting components. It is understood that the bottom of the supporting components is lower than the bottom of the optical transceiver body 5. When the top heat dissipation unit is combined with the optical transceiver body 5, the optical transceiver body 5 is in a suspended state, and the bottom heat dissipation unit can be snapped into all the supporting components and located below the optical transceiver body 5.

[0059] The dustproof unit is connected to the horizontal plate 6 via a plug-in component. It can be understood that in order to prevent dust accumulation on the top of the optical transceiver, the dustproof cover 1 can cover the outer top of the main body 5 of the optical transceiver, while facilitating the airflow delivered by the cooling fan 8. There is a certain space between the inner top of the top cover 1 and the horizontal plate 6 to allow the cooling fan 8 to rotate.

[0060] When the dustproof unit, top heat dissipation unit, optical transceiver body 5 and bottom heat dissipation unit are connected in combination, in response to the received heat dissipation signal, the cooling fan 8 is activated to deliver airflow to the top of the optical transceiver body 5 to dissipate heat from the top of the optical transceiver body 5, and airflow is delivered to the bottom of the optical transceiver body through the cavity in the horizontal plate 6, connecting components and supporting components. The bottom heat dissipation unit guides the airflow delivered to the bottom of the optical transceiver body to dissipate heat from the bottom of the optical transceiver body, thereby achieving overall heat dissipation of the optical transceiver.

[0061] It is understandable that the interiors of the horizontal plate 6, the connecting component, and the supporting component are all hollow structures. When the three are embedded and connected, their internal cavities are connected, and airflow can be delivered to the bottom of the optical transceiver body 5 within the internal cavity.

[0062] See Figure 1 , Figure 2 , Figure 6 As shown, the top cover 1 has two symmetrical grooves 2 on one side for engaging with the two ends of the horizontal plate 6; the other side of the top cover 1 has multiple through holes 7, and all through holes are covered with dust covers 19.

[0063] In this embodiment of the invention, two grooves 2 are formed on one set of sides of the top cover 1. When the dustproof unit is inserted into the horizontal plate 6 via the plug-in assembly, both ends of the horizontal plate 6 are engaged in the slots of the grooves 2. Multiple sets of through holes 7 are provided on another set of sides of the top cover 1, and a dustproof cover 19 is provided over the through holes 7. It can be understood that the dustproof cover has a hollow cavity structure. Therefore, when the cooling fan 8 delivers airflow to dissipate heat from the optical transceiver body 5, it can prevent dust accumulation while simultaneously allowing heat exchange between the air dissipated by the optical transceiver body 5 and the outside air.

[0064] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6 Each set of plug-in components includes a fixing plate 20, two sets of fixing strips 21, and a first engaging strip 22. The top of the fixing plate 20 is fixedly connected to the top of the inner top of the top cover 1. The two sets of fixing strips 21 are symmetrically arranged on the sides of the fixing plate 20, and the first engaging strip 22 is fixedly arranged at the bottom of the fixing plate 20. The horizontal plate is embedded with two sets of fixing grooves 9, which are used to engage with the plug-in components.

[0065] The optical transceiver body 5 has two second meshing strips 18 at its top ends. The second meshing strips 18 are used to mesh with the first meshing strip 22 when the dustproof unit is embedded in the horizontal plate 6 through the plug-in assembly.

[0066] In this embodiment of the invention, each set of plug-in components includes a fixing plate 20, two sets of fixing strips 21, and a first engaging strip 22, wherein the top of the fixing plate 20 is fixedly connected to the inner top of the top cover 1. When the dustproof unit is inserted into the horizontal plate 6 through the plug-in components, the fixing strips 21 on both sides of the fixing plate 20 are engaged with the inner side of the fixing groove 9, thus embedding the fixing plate 20 into the fixing groove 9. At the same time, second engaging strips 18 are provided at the corresponding positions of the groove openings of the fixing groove 9 at both ends of the outer top of the optical transceiver body 5. When the fixing plate 20 is inserted into the bottom of the fixing groove 9, the first engaging strip 22 at the bottom of the fixing plate 20 engages with the second engaging strip 18.

[0067] Please see Figure 1 and Figure 3 As shown, each set of connecting components includes a connecting plate 13 and a sliding plate 14. The connecting plate 13 and the sliding plate 14 are fixedly connected. The connecting plate 13 is respectively embedded with both ends of the horizontal plate 6 and the support component.

[0068] A set of outer sides of the optical transceiver body 5 are symmetrically provided with sliding grooves 12, which are used to slide the sliding plate 14 in the sliding grooves 12 and drive the top heat dissipation unit to move.

[0069] In this embodiment of the invention, each set of connecting components includes a connecting plate 13 and a sliding plate 14. The connecting plate 13 and the sliding plate 14 are fixedly connected. The connecting plate 13 is simultaneously embedded in both ends of the horizontal plate 6 and the support components, and symmetrical grooves 12 are provided on a set of outer surfaces of the optical transceiver body 5. When the horizontal plate 6 of the top heat dissipation unit, the two sets of connecting components, and the two sets of support components are combined and connected, the sliding plate 14 connected to the connecting plate 13 moves in the groove 12, driving the horizontal plate 6 and the support components embedded in the connecting plate 13 to move, thereby realizing the overall movement of the top heat dissipation unit.

[0070] Understandably, in order to facilitate the movement of the top heat dissipation unit by the sliding plate 14, the height of the sliding plate 14 on the connecting plate 13 is such that the main body 5 of the optical transceiver is in a certain suspended state while allowing it to be inserted and engaged with the sliding groove 12. At the same time, one end of the sliding groove 12 is an open groove, which facilitates the placement of the top heat dissipation unit on the top of the main body 5 of the optical transceiver through the sliding groove 12.

[0071] Please see Figure 1 The other outer side of the optical transceiver body 5 is provided with an indicator light 4 and multiple plug holes 3. The optical transceiver body 5 is provided with a motherboard. The indicator light 4 and all the plug holes 3 are electrically connected to the motherboard. The plug holes 3 are used to communicate with the motherboard through plug wires.

[0072] In this embodiment of the invention, another set of outer surfaces of the optical transceiver body 5 is provided with indicator lights 4 and multiple plug-in holes 3. The indicator lights 4 and all the plug-in holes 3 are electrically connected to the motherboard inside the optical transceiver body 5. When a signal interaction command is received, it is connected to the plug-in hole 3 through an external plug-in wire, thereby realizing signal interaction with the motherboard.

[0073] Please see Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the horizontal plate 6 is embedded with multiple hollow slots 11, which are used to dissipate heat from the top of the optical transceiver body 5 through airflow. Two sets of first connection holes 10 are symmetrically opened on the upper surface of the horizontal plate 6. Each support assembly includes a crossbar 15 and a rubber strip 16. The rubber strip 16 is located at the bottom of the crossbar 15, and multiple second connection holes 17 are opened on the inner side of the crossbar 15. Each connection assembly is respectively embedded with both ends of the horizontal plate 6 and the crossbar 15, and is used to output the airflow input by the cooling fan 8 through the first connection holes 10 to the bottom of the optical transceiver body 5 through the second connection holes 17.

[0074] The bottom heat dissipation unit includes two sets of plug-in plates 23 and a middle plate 27. The middle plate 27 has plug-in slots 26 on both sides. The plug-in end of the plug-in plate 23 is connected to the plug-in slot 26 via a spring 25, and the snap-fit ​​end of the plug-in plate 23 is snapped into place by the elastic force of the spring 25 against the rubber strip 16. Each set of plug-in plates 23 has multiple arc-shaped plates 24, and each arc-shaped plate 24 has ventilation holes 28 with the hole width increasing sequentially from the plug-in end to the snap-fit ​​end.

[0075] In this embodiment of the invention, the horizontal plate 6 is embedded with multiple hollow slots 11. When the cooling fan 8 responds to the cooling signal and delivers airflow, the airflow acts on the hollow slots 11 to dissipate heat on the top of the optical transceiver body 5. Each set of support components includes a horizontal bar 15 and a rubber strip 16. The connecting components are respectively embedded with both ends of the horizontal plate 6 and the horizontal bar 15. The bottom heat dissipation unit includes two sets of plug-in plates 23 and a middle plate 27. The middle plate 27 has plug-in slots 26 on both sides. One end of the two sets of plug-in plates 23 serves as the plug-in end and is connected to the plug-in slot 26 through a spring 25. The other end of the two sets of plug-in plates 23 serves as the snap-fit ​​end and is snap-fitted with the rubber strip 26 under the elastic force of the spring 25. Each set of plug-in plates 23 is provided with multiple arc-shaped plates 24. Each arc-shaped plate 24 is provided with a vent hole 28, and the width of the vent hole 28 of the arc-shaped plate 24 on each set of plug-in plates 23 increases sequentially from the plug-in end to the snap-fit ​​end. When the cooling fan responds to the received cooling signal, airflow is input into the inner cavity of the horizontal plate 6 through two sets of first connection holes 10 symmetrically opened on the upper surface of the horizontal plate 6. Through the inner cavity of the horizontal plate 6, which communicates with the connecting components and the crossbar 15, airflow is output from multiple second connection holes 17 on the inner side of the crossbar 15 to the bottom of the optical transceiver body 5. After the airflow reaches the bottom of the optical transceiver body 5, it is guided through the arc-shaped plate 24 and the vents 28 on the arc-shaped plate 24, thereby better dissipating heat from the bottom of the optical transceiver body 5.

[0076] Understandably, the spring in the connector slot can be used to disconnect the connector plate from the rubber strip, allowing for cleaning of the connector plate.

[0077] Optionally, the vent width of the arc-shaped plate on each set of plug-in plates increases sequentially from the plug-in end to the snap-fit ​​end with the same width dimension.

[0078] This invention features a plug-in assembly and a cooling fan located at the top of the dustproof unit's top cover. The top cooling unit includes a horizontal plate, two sets of connecting components, and two sets of supporting components. The horizontal plate is connected to the supporting components at both ends via the connecting components, and the dustproof unit is embedded in the horizontal plate via the plug-in assembly. The bottom cooling unit is snapped into place below the main body of the optical transceiver. Upon receiving a cooling signal, the cooling fan delivers airflow to the top of the optical transceiver and through cavities within the horizontal plate, connecting components, and supporting components to the bottom of the main body. The bottom cooling unit further guides the airflow. This combination of the top and bottom cooling units, along with the airflow from the cooling fan, allows for simultaneous cooling of both the top and bottom of the optical transceiver, improving the overall cooling performance of the transceiver.

[0079] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
