Description

Technical Field

[0001] This application relates to the technical field of communication power supplies, and in particular to a pluggable surge protection module for communication power supplies. Background Technology

[0002] With the development and expansion of information technology and data services, the emergence of new-generation communication base station power supplies, such as the current 5G communication base station power supplies, provides stable power guarantees for high-precision equipment and intelligent information systems. Among these, surge protectors are key components within the communication power supply and also serve as protective devices to safeguard the communication power supply.

[0003] Surge protectors in related technologies are generally loosely structured and large in size. They are installed vertically inside the communication power supply using bolts and nuts. When the communication base station power supply is struck by lightning, the surge protector will divert the instantaneous large current to the ground and release it, thereby ensuring the safety of the electrical equipment.

[0004] Regarding the aforementioned technologies, the inventors believe that: because surge protectors in the aforementioned technologies generally have a loose structure and are vertically installed inside the power supply, they occupy a lot of installation space, resulting in a large overall size of the surge protector, which is inconvenient to install; at the same time, the installation method of using bolts and nuts makes replacement and disassembly quite cumbersome.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a pluggable surge protector module for communication power supplies. (Refer to...) Figure 1 In this embodiment, the pluggable surge protection module includes surge protection components 1 and connecting units. Four surge protection components 1 are provided, and these four components are securely connected in series via the connecting units. All four surge protection components 1 are simultaneously connected in series with the outdoor live wire, neutral wire, and ground wire. The four surge protection components 1, securely connected in series, are horizontally fixedly inserted into the frame of the communication power supply, occupying a small installation space, thus achieving the modularity and miniaturization of the overall surge protector.

[0026] Specifically, refer to Figure 1 and Figure 2 In this embodiment, the surge protection component 1 includes a base 11, a top cover 12, a varistor unit, an electrode clamp unit, a tripping unit, and a sensing unit. The base 11 is a rectangular frame with a hollowed-out top, and the top cover 12 tightly covers the top of the base 11. The varistor unit is installed in the center of the interior of the base 11, and the electrode clamp unit is installed on one side of the interior of the base 11. One side of the electrode clamp unit is connected to the varistor unit, and the other side of the electrode clamp unit is clamped and connected to the inside of the communication power supply frame, thereby ensuring a stable installation of the overall surge protection module.

[0027] The trip unit is installed between the base 11 and the varistor unit, with one end of the trip unit snapped into the varistor unit and the other end of the trip unit connected to the electrode clamp unit; the sensing unit is installed between the four lightning protection components 1, and the sensing unit cooperates with each of the trip units.

[0028] When the communication power supply is struck by lightning, the powerful current damages the varistor, causing the trip unit to detach from the varistor. The trip unit then automatically slides to contact the sensing unit. The sensing unit detects the contact action of the trip unit and sends an alarm signal. In this way, the structure of the varistor, electrode clip unit, trip unit, and sensing unit working together can effectively protect the entire communication power supply and prevent damage to the entire communication power supply.

[0029] At the same time, refer to Figure 1 and Figure 2In this embodiment, the connecting unit includes a fixed concave tube 111, a fixed convex tube 121, and copper rivets 2. Multiple fixed concave tubes 111 are provided, each installed inside a base 11. The fixed concave tubes 111 in the four bases 11 are installed at the same position, and the fixed concave tubes 111 at the same position in the four bases 11 are interconnected. Multiple fixed convex tubes 121 are provided, each installed at the bottom of a top cover 12 and interconnected with the top cover 12. The number of fixed convex tubes 121 is the same as the number of fixed concave tubes 111 and they correspond to each other. The fixed convex tubes 121 and fixed concave tubes 111 cooperate with and are interconnected. When the top cover 12 is closed on top of the base 11, the fixed convex tubes 121 of the top cover 12 are securely inserted into the fixed concave tubes 111 of the base 11.

[0030] Multiple copper rivets 2 are provided, and the number of copper rivets 2 is the same as the number of fixed concave tubes 111 and fixed convex tubes 121. The copper rivets 2 cooperate with the fixed concave tubes 111 and fixed convex tubes 121 respectively. By using the copper rivets 2, they can be inserted into the corresponding fixed concave tubes 111 and fixed convex tubes 121 at the same time to securely connect the four lightning protection components 1 in series.

[0031] Preferably, a fixing limiting ring 21 is fixedly installed at both ends of each of the copper rivets 2, and multiple limiting grooves 22 are provided at the bottom of the base 11 and the top of the cover 12. The limiting grooves 22 are respectively connected to the fixing concave tube 111 and the fixing convex tube 121, and the limiting grooves 22 are engaged with the fixing limiting rings 21. By setting the fixing limiting rings 21, the copper rivets 2 can be more securely engaged in the lightning protection components 1, thereby achieving a stable connection effect for the lightning protection components 1.

[0032] On the other hand, the copper rivet 2 and the fixing limiting ring 21 can also be detachably configured. In this way, the fixing limiting ring 21 is tightly fitted onto the copper rivet 2, and the fixing limiting ring 21 and the limiting groove 22 are engaged with each other. This not only achieves the effect of stabilizing and limiting the copper rivet 2, but also allows the copper rivet 2 to be removed from the lightning protection components 1 by removing the fixing limiting ring 21 from the copper rivet 2, so as to facilitate the disassembly of the lightning protection components 1.

[0033] In addition, the structure of the pressure-sensitive unit, electrode clip unit, tripping unit, and sensing unit is described in detail below: Specifically, refer to Figures 2-4In this embodiment, the pressure-sensitive unit includes a limiting block 112, a pressure-sensitive fixing base 3, a pressure-sensitive resistor 32, a pressure-sensitive fixing frame 31, and a discharge tube 52. Multiple limiting blocks 112 are provided and fixedly installed inside the base 11. The pressure-sensitive fixing base 3 is placed between the limiting blocks 112, which securely limit and engage the pressure-sensitive fixing base 3 around its perimeter, thereby ensuring that the pressure-sensitive fixing base 3 is securely installed in the center of the interior of the base 11.

[0034] Three varistors 32 are provided, and the three varistors 32 are respectively placed inside the three varistor mounting bases 3. The varistor mounting bases 3 provide a stable locking effect for the varistors 32, thereby ensuring that the varistors 32 are securely installed inside the varistor mounting bases 3. The top of the varistor mounting base 3 has a notch, and the top of the varistor 32 extends out of the varistor mounting base 3 along the notch. The tops of the three varistors 32 respectively cooperate with three tripping units, so that the tripping units lock and limit the top of the varistor 32.

[0035] Meanwhile, the bottoms of the three varistors 32 are respectively connected to the three electrode clamp units, so that the electrode clamp units can effectively support the bottom of the varistor 32. This not only allows the varistor 32 to be placed in the varistor fixing base 31, but also allows the varistor 32 to be connected to the electrode clamp units.

[0036] A varistor mounting bracket 31 is installed inside the lowest varistor mounting base 3, and a discharge tube 52 is placed inside the varistor mounting bracket 31. The varistor mounting bracket 31 limits the position of the discharge tube 52, thus ensuring that the discharge tube 52 is securely installed inside the varistor mounting base 3. The top of the discharge tube 52 extends out of the varistor mounting base 3 along a notch, and the top of the discharge tube 52 cooperates with the lowest tripping unit, while the bottom of the discharge tube 52 cooperates with the lowest electrode clamp unit. Furthermore, the discharge tube 52 is connected in parallel with the external neutral and ground wires. After a lightning strike, the discharge tube 52 can guide the current along the neutral and ground wires to the ground, thereby ensuring the safety of the electrical equipment.

[0037] Additionally, refer to Figure 2 and Figure 3 In this embodiment, the electrode clamp unit includes a first electrode clamp 4, a second electrode clamp 5, a first electrode copper sheet 41, and a second electrode copper sheet 51. Electrode clamp mounting positions are symmetrically installed on one side of the inner surface of the base 11. The first electrode clamp 4 and the second electrode clamp 5 are respectively installed inside these two mounting positions, which securely limit the first electrode clamp 4 and the second electrode clamp 5, ensuring that they are firmly installed on one side of the inner surface of the base 11.

[0038] A first electrode slot 13 is symmetrically provided on one side of the surge protection component 1, that is, the first electrode slots 13 on the four surge protection components 1 are interconnected; and the two first electrode slots 13 of the surge protection component 1 respectively cooperate with the first electrode clip 4 and the second electrode clip 5, so that the first electrode clip 4 and the second electrode clip 5 are not only clamped and connected to the inside of the communication power supply frame through the first electrode slot 13; but also the surge protection components 1 can be quickly removed from the inside of the communication power supply frame, thus making the surge protection module easier to replace and remove, so as to achieve the effect of easy replacement of the surge protection module.

[0039] Meanwhile, the first electrode copper sheet 41 has an L-shaped structure. One side of the first electrode copper sheet 41 is fixedly connected to the side of the first electrode clamp 4 away from the first electrode slot 13. The side of the first electrode copper sheet 41 away from the first electrode clamp 4 is fixedly connected to the tripping unit. An L-shaped groove is provided on the top side of the pressure-sensitive fixing seat 3. The L-shaped groove and the first electrode copper sheet 41 cooperate with each other, so that the L-shaped groove on the pressure-sensitive fixing seat 3 effectively limits the first electrode copper sheet 41.

[0040] The second electrode copper sheet 51 is fixedly connected to the side of the second electrode clamp 5 away from the first electrode slot 13. The bottoms of the three uppermost varistors 32 are respectively pressed against the sides of the three uppermost second electrode copper sheets 51 away from the second electrode clamp 5; the bottom of the lowermost discharge tube 52 is pressed against the side of the lowermost second electrode copper sheet 51 away from the second electrode clamp 5. This not only securely mounts the varistor 32 and discharge tube 52 to the varistor mounting base 3, but also connects the electrode clamp unit to the varistor unit and the tripping unit, enabling an alarm signal to be issued in the event of a lightning strike.

[0041] In addition, refer to Figure 2 and Figure 3 In this embodiment, the tripping unit includes a tripping bracket 6, a tripping limiting plate 61, a tripping point 611, an elastic component, and a contact component. The tripping bracket 6 is slidably disposed at the top center of the pressure-sensitive fixing base 3, and a sliding groove 33 is formed on the top of the pressure-sensitive fixing base 3. The sliding groove 33 cooperates with the tripping bracket 6, allowing the tripping bracket 6 to move along the sliding groove 33 on the top of the pressure-sensitive fixing base 3. The tripping limiting plate 61 is L-shaped, with one side extending into the L-shaped groove of the pressure-sensitive fixing base 3, and one side of the tripping limiting plate 61 is fixedly connected to the side of the first electrode copper sheet 41 facing away from the first electrode clamp 4. The side of the tripping limiting plate 61 facing away from the first electrode copper sheet 41 is pressed against and engaged with the top of the tripping bracket 6 to engage and limit the tripping bracket 6.

[0042] The tripping point 611 is installed on the side of the tripping limiting plate 61 away from the first electrode copper sheet 41. The tripping point 611 engages and abuts against the top of the varistor 32 to achieve a stable fit with the varistor 32. In this embodiment, the tripping limiting plate 61 has a certain elasticity. When struck by lightning, the varistor 32 is damaged, and the tripping point 611 disengages from the varistor 32. Under the elastic action of the tripping limiting plate 61, the tripping limiting plate 61 moves the tripping point 611 upward, thereby causing the tripping limiting plate 61 to release its restriction on the tripping bracket 6.

[0043] Meanwhile, two elastic components are provided, symmetrically installed on both sides of the trip bracket 6 and between the top two sides of the pressure-sensitive fixing base 3, to effectively pull the trip bracket 6. The contact component is located on one of the elastic components away from the first electrode copper sheet 41, and the contact component cooperates with the sensing unit. When the limiting of the trip bracket 6 is removed, the two elastic components pull the trip bracket 6, causing the trip bracket 6 to slide along the sliding groove 33 on the top of the pressure-sensitive fixing base 3. This causes the trip bracket 6 to drive the contact component to contact the sensing unit, thereby causing the sensing unit to sense the contact action of the trip unit and issue an alarm signal.

[0044] Specifically, refer to Figure 3 In this embodiment, the elastic component includes a fixing plate 62, a first fixing post 621, a second fixing post 341, and a tripping spring 63. The fixing plate 62 is mounted on one side of the tripping bracket 6, and a fixing groove 34 is formed on the top of the pressure-sensitive fixing seat 3. The fixing plate 62 and the fixing groove 34 cooperate with each other. During the movement of the tripping bracket 6, the fixing plate 62 moves along the fixing groove 34. The first fixing post 621 is fixedly mounted on the top of the fixing plate 62, and the second fixing post 341 is fixedly mounted on the side wall of the fixing groove 34 near the first electrode slot 13. The first fixing post 621 and the second fixing post 341 correspond to each other and are on the same straight line.

[0045] The release spring 63 is disposed between the first fixed post 621 and the second fixed post 341, and the two ends of the release spring 63 are respectively fixedly connected with a first buckle and a second buckle. The first buckle is fastened in the first fixed post 621 and the second buckle is fastened in the second fixed post 341 to install the release spring 63.

[0046] When the limit on the trip bracket 6 is removed, under the elastic reset action of the two trip springs 63, the trip springs 63 pull the first fixed post 621 on the fixed plate 62, so that the two fixed plates 62 simultaneously drive the trip bracket 6 to move along the sliding groove 33, thereby causing the trip bracket 6 to drive the contact component to contact the sensing unit.

[0047] At the same time, refer to Figure 3 In this embodiment, the touch assembly includes a tripping connecting rod 64 and a tripping touch block 641. The tripping connecting rod 64 is fixedly installed on the side of the fixing plate 62 away from the tripping bracket 6, and the tripping connecting rod 64 is located in one of the fixing grooves 34 away from the first electrode copper sheet 41. The tripping touch block 641 is fixedly installed at the end of the tripping connecting rod 64 facing the first electrode groove 13, and the tripping touch block 641 is perpendicular to the tripping connecting rod 64.

[0048] When the tripping bracket 6 moves under the action of the tripping spring 63, the tripping bracket 6 drives the tripping connecting rod 64 on the fixed plate 62 to move. The tripping connecting rod 64 drives the tripping contact block 641 to move forward along the fixed groove 34, so that the tripping contact block 641 touches the sensing unit, thereby causing the sensing unit to issue an alarm signal.

[0049] Furthermore, refer to Figure 2 and Figure 3 In this embodiment, the sensing unit includes a sensing circuit board 7, a micro switch 71, and a remote signaling electrode clip 72. The sensing circuit board 7 is installed inside the four bases 11, and the first three bases 11 and the last three top covers 12 are all provided with interconnected mounting slots 14. The sensing circuit board 7 cooperates with the mounting slots 14 so that the sensing circuit board 7 is installed in the mounting slots 14, thereby connecting the interiors of these lightning protection components 1 in series.

[0050] Four microswitches 71 are provided, and the four microswitches 71 are soldered to the surface of the sensing circuit board 7 away from the first electrode slot 13. The microswitches 71 cooperate with the trip contact block 641. The remote signaling electrode clip 72 is soldered to the surface of the sensing circuit board 7 away from the microswitches 71. The remote signaling electrode clip 72 is located inside the lightning protection component 1 and cooperates with the microswitches 71.

[0051] Meanwhile, a second electrode slot 15 is provided on one side of each of the four lightning protection components 1. The second electrode slot 15 is located between the two first electrode slots 13, and the second electrode slot 15 cooperates with the remote signaling electrode clamp 72. The external monitoring system is connected through the cooperation of the second electrode slot 15 and the remote signaling electrode clamp 72.

[0052] When the surge protection module is working normally, the remote signaling electrode clip 72 is closed-loop connected to the external monitoring system. When the surge protection module is struck by lightning, causing the varistor 32 to fail, the trip contact block 641 and the micro switch 71 come into contact with each other. The micro switch 71 can send an alarm signal, and then the micro switch 71 feeds the alarm signal back to the remote signaling electrode clip 72, which in turn feeds the alarm signal back to the external monitoring system. The external monitoring system then controls the remote signaling electrode clip 72 to disconnect from the external monitoring system, thereby protecting the external monitoring system.

[0053] Better, refer to Figure 2 and Figure 5 In this embodiment, a tripping indicator unit is also provided between the base 11 and the tripping connecting rod 64. The tripping indicator unit includes a fixed frame 8, a slider 81, a push spring 82, and an indicator window 113. The fixed frame 8 is fixedly installed on the inner side wall of the base 11 away from the first electrode slot 13. The slider 81 is slidably disposed inside the fixed frame 8. One end of the push spring 82 is connected to the inside of the slider 81, and the other end of the push spring 82 is connected to the inner side wall of the fixed frame 8. Through the elastic extension and contraction function of the push spring 82, the slider 81 can move inside the fixed frame 8.

[0054] Meanwhile, the indicator window 113 is located on the side of the base 11 away from the first electrode slot 13, and a green indicator light 642 is installed on the end of the trip connecting rod 64 away from the trip contact block 641. The green indicator light 642 can emit green light; a red indicator light 811 is installed on the side of the slider 81 away from the push spring 82. The red indicator light 811 can emit red light.

[0055] When the surge protection module is in normal condition, the green indicator light 642 on the trip connection rod 64 abuts against the inner side wall of the base 11, and the lamp head of the green indicator light 642 faces the indicator window 113. At the same time, under the action of the push spring 82, the red indicator light 811 on the slider 81 abuts against one side of the green indicator light 642. In this way, the green light can be observed at the indicator window 113, thereby ensuring the normal use of the surge protection module.

[0056] When struck by lightning, the varistor 32 is damaged, and the trip point 611 disengages from the varistor 32. The trip connecting rod 64 moves the green indicator light 642 away from the indicator window 113. At this time, the slider 81 is pushed by the spring 82 to move, and the slider 81 moves the red indicator light 811 to the indicator window 113. In this way, the red light can be observed in the indicator window 113, which can effectively warn maintenance personnel.

[0057] In this embodiment, each of the four bases 11 is also provided with a snap-fit ​​unit, which can securely snap the surge protection module into the frame of the communication power supply. Specifically, refer to... Figure 2 and Figure 5 The snap-fit ​​unit includes a snap-fit ​​frame 9, a sliding snap-fit ​​block 91, a snap-fit ​​spring 92, a snap-fit ​​buckle 911, a push plate 93, and a stop block 931. The snap-fit ​​frame 9 is fixedly installed inside the base 11, located on the side of the pressure-sensitive fixing seat 3 away from the electrode clamp unit. The sliding snap-fit ​​block 91 is slidably disposed inside the snap-fit ​​frame 9. One end of the snap-fit ​​spring 92 is connected to one side of the sliding snap-fit ​​block 91, and the other end is connected to the inner side of the snap-fit ​​frame 9. The snap-fit ​​buckle 911 is installed on the side of the sliding snap-fit ​​block 91 away from the snap-fit ​​spring 92, and a mating groove 114 is formed on one side of the base 11. The mating groove 114 and the snap-fit ​​buckle 911 cooperate with each other. Under the elastic action of the snap-fit ​​spring 92, the snap-fit ​​spring 92 pushes the snap-fit ​​buckle 911 on the sliding snap-fit ​​block 91 out of the mating groove 114.

[0058] Furthermore, a slot is provided inside the frame of the communication power supply to engage with the latch 911. The latch 911 on the sliding block 91 is inserted into the slot to securely fasten the surge protection module inside the frame of the communication power supply. A push groove 115 is provided on the side of the base 11 away from the first electrode slot 13. One side of the push plate 93 extends out of the base 11 along the push groove 115, and the other side of the push plate 93 extends into the locking frame 9 along the push groove 115. The push plate 93 and the sliding block 91 cooperate with each other. A stop block 931 is fixedly installed on one side of the push plate 93 and abuts against the inner wall of the base 11 to prevent the push plate 93 from sliding out of the base 11.

[0059] When the surge protection module needs to be disassembled, the push plates 93 are pushed inward simultaneously. The push plates 93 press against the sliding block 91 along the push groove 115, and the sliding block 91 compresses the locking spring 92. The sliding block 91 then causes the latch 911 to retract along the mating groove 114, thereby separating the latch 911 from the slot, facilitating the unlocking of the surge protection module for disassembly. Conversely, when the pressure on the push plates 93 is released, the locking spring 92 pushes the sliding block 91 to move. The sliding block 91 then causes the latch 911 to engage with the slot inside the frame along the mating groove 114, facilitating the secure installation of the surge protection module.
