Abstract
Description
Technical Field
[0001] This invention relates to the field of lightning protection device technology, and in particular to a surge protector. Background Technology
[0002] A surge protector is an electronic device that provides safety protection for various electronic devices, instruments, and communication lines. When a surge current or voltage spike suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and discharge the surge current in a very short time, thereby preventing damage to other equipment in the circuit.
[0003] The 1U device, conforming to EIA specifications and measuring 4.445cm in thickness, is specifically designed for specialized applications and high-density computing environments. With the rapid development of enterprise informatization, the demand for servers is increasing. How to rationally plan and implement solutions within limited installation space is crucial. The main advantages of the 1U device lie in its space-saving and modular design, effectively saving energy, maintenance, and environmental costs. While the modular, universal design significantly reduces size, it also results in less usable internal space. The limited assembly space of the 1U device strictly restricts the structural dimensions of the surge protector, while simultaneously demanding high performance from it. Existing 1U removable surge protectors have low current-carrying capacity, limited tripping reliability, and incomplete failure indication functions. When encountering overvoltage causing the surge protector to trip, they cannot guarantee reliable electrical disconnection, failing to ensure equipment protection and resulting in lower safety. Summary of the Invention
[0004] The technical problem to be solved and the technical task proposed by the present invention is to improve the existing technology and provide a surge protector that solves the problem that the current surge protectors are difficult to meet the requirements of large current carrying capacity and tripping reliability within a limited size.
[0005] To solve the above technical problems, the technical solution of the present invention is as follows:
[0006] A surge protector includes a core assembly comprising an overvoltage protection element one, an overvoltage protection element two, a tripping mechanism one, a tripping mechanism two, and a main body supporting each component. One pin of the overvoltage protection element one is connected to an electrode one on the main body via the tripping mechanism one, and the other pin of the overvoltage protection element one is connected to an electrode two on the main body. One pin of the overvoltage protection element two is connected to an electrode one on the main body via the tripping mechanism two, and the other pin of the overvoltage protection element two is connected to an electrode three on the main body. The tripping mechanism one, the overvoltage protection element one, the overvoltage protection element two, and the tripping mechanism two are stacked sequentially, and the overvoltage protection element one and the overvoltage protection element two are insulated from each other. The surge protector described in this invention has a compact structure and occupies little space, meeting the needs of miniaturization. Overvoltage protection element one and tripping mechanism one protect the first electrode from the second electrode. Overvoltage protection element two and tripping mechanism two protect the first electrode from the third electrode. Overvoltage protection element one and tripping mechanism one, and overvoltage protection element two and tripping mechanism two also protect the second electrode from the third electrode. This achieves multi-path protection while requiring fewer components, effectively improving current carrying capacity and the performance of multi-path protection. It features a double tripping structure, reliably disconnecting the circuit when the current is too high or the overvoltage protection element fails, causing a temperature rise and achieving electrical isolation. This prevents continuous flow of fault current, effectively protecting the load devices, and offers high reliability and safety.
[0007] Furthermore, the interior of the main body is an assembly chamber for assembling overvoltage protection element one and overvoltage protection element two. The main body includes a cover body one and a cover body two, which are joined together to form the assembly chamber. A partition is also provided within the assembly chamber to insulate and separate overvoltage protection element one and overvoltage protection element two. Overvoltage protection element one and overvoltage protection element two are enclosed in the assembly chamber and kept mutually insulated, which improves electrical isolation and ensures that overvoltage protection element one and overvoltage protection element two operate independently and reliably. A failure in one of them will not affect the normal operation of the other, thus improving reliability.
[0008] Furthermore, the pins of the overvoltage protection element one connected to the electrode two protrude out of the assembly chamber, and the main body is provided with an isolation chamber one for covering the connection between the electrode two and the pins of the overvoltage protection element one. The pins of the overvoltage protection element two connected to the electrode three protrude out of the assembly chamber, and the main body is provided with an isolation chamber two for covering the connection between the electrode three and the pins of the overvoltage protection element two. This improves the insulation between the electrodes, prevents discharge conduction between the electrodes, and ensures the insulation safety of the surge protector when a large surge current passes through.
[0009] Furthermore, tripping mechanism one and tripping mechanism two are located outside the assembly chamber, and are symmetrically arranged on both sides of the assembly chamber. Openings are respectively provided on the walls of the two opposite sides of the assembly chamber. The release spring of tripping mechanism one and the pin of overvoltage protection element one are connected at the opening using low-temperature solder to form a release joint. The release spring of tripping mechanism two and the pin of overvoltage protection element two are connected at another opening using low-temperature solder to form a release joint. The structure is simple. When encountering an extremely large overload current, after the release spring trips from the pin of the overvoltage protection element, it can separate from the pin of the overvoltage protection element due to its own elasticity, thereby achieving the function of disconnecting the circuit, effectively protecting the equipment, and improving operational safety.
[0010] Furthermore, the first and second release springs are integrated into a single unit. One end of the U-shaped elastic sheet forms the first release spring, and the other end forms the second release spring. The middle of the U-shaped elastic sheet is connected to the first electrode. This design is simple, compact, easy to implement, and has few components. It also improves the structural stability of the first and second release springs, in other words, it enhances their resilience. This allows them to separate sufficiently from the pins of the overvoltage protection element one and the overvoltage protection element two after tripping, thereby improving protection performance and safety.
[0011] Furthermore, the tripping mechanism also includes an arc-shielding element and an elastic element. The elastic element is in an energy-storing state before the pin of the release spring is disconnected from the pin of the overvoltage protection element. After the release spring is separated from the pin of the overvoltage protection element, the elastic element pushes the arc-shielding element to move between the release spring and the pin of the overvoltage protection element for electrical isolation.
[0012] The second tripping mechanism also includes an arc-shielding element and an elastic element. The elastic element is in an energy-storing state before the pin of the second release spring and the second overvoltage protection element are disconnected. After the second release spring and the pin of the second overvoltage protection element are separated, the elastic element pushes the arc-shielding element to move between the second release spring and the pin of the second overvoltage protection element for electrical isolation.
[0013] By using arc-shielding component one and arc-shielding component two to improve the electrical isolation effect after tripping, the arc can be effectively extinguished and the reliability of protection can be improved.
[0014] Furthermore, it also includes a housing covering the core assembly and a status indicator mechanism on the housing. The status indicator mechanism includes a linkage component, a status indicator section, and an indicator window on the housing that cooperates with the status indicator section. Arc-shielding component one and arc-shielding component two drive the status indicator section to switch states via the linkage component, which includes multi-stage sequentially driven linkage components. The status indicator mechanism visually displays the operating status of the surge protector. When the tripping mechanism one or tripping mechanism two of the surge protector trips and disconnects the circuit, arc-shielding component one and arc-shielding component two move, thereby driving the status indicator section to move via the linkage component to switch states. Different states are then displayed in the indicator window, allowing staff to promptly grasp the operating status of the surge protector, facilitating timely maintenance and ensuring long-term stable protection.
[0015] Furthermore, the linkage assembly includes a primary linkage component and a secondary linkage component, which are rotatably mounted on the outer casing. The primary linkage component is driven to rotate by arc-shielding component one and arc-shielding component two, and the secondary linkage component is driven to rotate by the primary linkage component. The status indicator is mounted on the secondary linkage component. The structure is simple and compact, easy to implement, and the multi-stage transmission method extends the transmission distance, avoids the impact of excessively long individual components on transmission reliability, and ensures accurate and reliable status indication.
[0016] Furthermore, it also includes a remote signaling component. The arc-shielding component one and the arc-shielding component two touch the same remote signaling component, so that if either the tripping mechanism one or the tripping mechanism two trips, it will trigger the remote signaling component to generate a remote signaling signal, which facilitates remote monitoring of the working status of the surge protector.
[0017] Furthermore, at least one of the electrodes one, two, and three is connected to both a pin for connection to the base and an external port, facilitating the connection of external cables to achieve multi-functionality.
[0018] Furthermore, the external port includes a conductive part, an elastic crimping member, and a pushing member. The conductive part is electrically connected to one of the first electrode, the second electrode, and the third electrode. The elastic crimping member elastically abuts against the conductive part to clamp the terminal inserted between the conductive part and the elastic crimping member. The pushing member is adjustable against the elastic crimping member to adjust the elastic force applied by the elastic crimping member. The structure is simple, convenient for connecting external cables, and ensures the reliability of the wiring connection.
[0019] Compared with the prior art, the advantages of the present invention are as follows:
[0020] The surge protector described in this invention has a compact structure and occupies little space, meeting the needs of miniaturization.

Detailed Implementation
[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0030] The surge protector disclosed in this invention has a compact structure, occupies little space, meets the requirements of large current carrying capacity, has high tripping reliability, and has reliable protection performance, meeting the needs of miniaturization development.
[0031] like Figures 1 to 6As shown, a surge protector mainly includes a core assembly. The core assembly includes an overvoltage protection element 1, an overvoltage protection element 2, a tripping mechanism 3, a tripping mechanism 4, and a main body 5. The overvoltage protection element 1, overvoltage protection element 2, tripping mechanism 3, and tripping mechanism 4 are carried by the main body 5. One pin of the overvoltage protection element 1 is connected to an electrode 61 on the main body 5 via the tripping mechanism 3, and the other pin is connected to an electrode 62 on the main body 5. One pin of the overvoltage protection element 2 is connected to an electrode 61 on the main body 5 via the tripping mechanism 3, and the other pin is connected to an electrode 63 on the main body 5. The tripping mechanism 1, overvoltage protection element 1, overvoltage protection element 2, and tripping mechanism 4 are all included. The two overvoltage protection elements are stacked sequentially, with the first overvoltage protection element 1 and the second overvoltage protection element 2 insulated from each other. This stacked layout is more reasonable and compact, effectively reducing the volume and meeting the needs of miniaturization. It also meets the requirements of high current carrying capacity, has high tripping reliability, and has reliable protection performance. The surge protector described in this embodiment forms a Y-shaped multi-channel protection circuit structure. Overvoltage protection element 1 and tripping mechanism 1 protect the first electrode from the second electrode. Overvoltage protection element 2 and tripping mechanism 2 protect the first electrode from the third electrode. Overvoltage protection element 1 and tripping mechanism 1, as well as overvoltage protection element 2 and tripping mechanism 2, protect the second electrode from the third electrode. This achieves multi-channel protection while requiring fewer components, resulting in a compact structure and small footprint.
[0032] The overvoltage protection element 1 and overvoltage protection element 2 can be either voltage-limiting elements or switching elements. Specifically, they can be varistors or gas discharge tubes, etc. Different types of elements have different functions or performance. In this embodiment, the overvoltage protection element 1 is a gas discharge tube, and the overvoltage protection element 2 is a varistor. Electrode 61 and electrode 63 are working electrodes, while electrode 62 is a grounding electrode. The surge protector is a pluggable module. When the surge protector is plugged into the base, electrode 61 and electrode 63 are connected to the neutral wire and live wire on the base, respectively, and electrode 62 is connected to the grounding wire on the base, thereby realizing multi-path protection between the neutral wire, live wire, and grounding wire.
[0033] In this embodiment, the interior of the main body 5 is an assembly chamber for assembling overvoltage protection element 1 and overvoltage protection element 2. This assembly chamber is a relatively enclosed space, which isolates overvoltage protection element 1 and overvoltage protection element 2 from the outside, improving electrical isolation. Even if overvoltage protection element 1 or overvoltage protection element 2 fails, the assembly chamber can still isolate them, better preventing the fault from escalating and reducing losses. Specifically, the main body 5 includes a cover 51 and a cover 52, which are assembled to form the assembly chamber. The chamber has a simple structure, is easy to implement, and is convenient to assemble and disassemble. The first cover 51 and the second cover 52 are snapped together, which can conveniently encapsulate the first overvoltage protection element 1 and the second overvoltage protection element 2 in a relatively isolated space, ensuring both isolation effect and ease of assembly and disassembly. In addition, a partition layer 53 is provided in the assembly chamber to insulate and separate the first overvoltage protection element 1 and the second overvoltage protection element 2, improving the insulation isolation effect between the first overvoltage protection element 1 and the second overvoltage protection element 2, ensuring that they work independently and reliably, and avoiding the failure of one affecting the normal operation of the other.
[0034] In this embodiment, the pin of the overvoltage protection element 1 connected to the electrode 2 62 extends out of the assembly chamber, and the main body 5 is provided with an isolation chamber 54 for covering the connection between the electrode 2 62 and the pin of the overvoltage protection element 1. The pin of the overvoltage protection element 2 connected to the electrode 3 63 extends out of the assembly chamber, and the main body 5 is provided with an isolation chamber 55 for covering the connection between the electrode 3 63 and the pin of the overvoltage protection element 2. That is, the connection between the pins of the electrode 2 62 and the overvoltage protection element 1, and the connection between the electrode 3 63 and the overvoltage protection element 2 are isolated from the surrounding environment, which can improve the insulation capability between the electrodes, avoid the discharge conduction between the electrodes, ensure the insulation safety of the surge protector when a large surge current passes through, and improve the reliability of the surge protector. Furthermore, the pins of the overvoltage protection element 1 are provided with sockets, and the electrode 2 62 is provided with an insertion part for inserting into the socket. The insertion part is inserted into the socket and then soldered to improve the reliability of the electrical connection between the electrode 2 62 and the pins of the overvoltage protection element 1, ensuring that the surge protector can stably perform its protective function. Similarly, the pins of the electrode 3 63 and the overvoltage protection element 2 2 can also adopt a similar connection structure to improve the connection reliability. The main body 5 is provided with channels for respectively engaging and fixing the electrodes 1 61, 2 62, and 3 63 and for the wiring of the electrodes 1 61, 2 62, and 3 63. This allows for convenient assembly or disassembly of the electrodes 1 61, 2 62, and 3 63, while ensuring the connection stability of the electrodes 1 61, 2 62, and 3 63 on the main body 5.
[0035] Tripping mechanisms one and two are located outside the assembly chamber, and are symmetrically arranged on both sides of the assembly chamber. Tripping mechanism one (3) is isolated from overvoltage protection element one (1) by the wall of the assembly chamber, and tripping mechanism two (4) is also isolated from overvoltage protection element two (2) by the wall of the assembly chamber, thus improving the electrical isolation effect after tripping. Tripping mechanism one includes a release spring (31), an arc-shielding element (32), and an elastic element (33). Tripping mechanism two includes a release spring (41), an arc-shielding element (42), and an elastic element (43). Openings are respectively provided on the walls of the two opposite sides of the assembly chamber. These openings are specifically located on the walls at both ends of the stacking direction of tripping mechanism one, overvoltage protection element one (1), overvoltage protection element two (2), and tripping mechanism two (2). The release spring (31) is isolated from overvoltage protection element one (1). The pins are connected at the port with low-temperature solder to form a release point. The pins of the release spring 41 and the overvoltage protection element 2 are connected at another port with low-temperature solder to form a release point. The release spring 31 and the release spring 41 are simultaneously connected to the electrode 61. Under normal operating conditions, the overvoltage protection element 1 is electrically connected to the electrode 61 through the release spring 31, and the overvoltage protection element 2 is electrically connected to the electrode 61 through the release spring 41. When the current is too high or the overvoltage protection element 1 or the overvoltage protection element 2 fails and causes the temperature to rise, the low-temperature solder melts. The release spring 31 separates from the overvoltage protection element 1 under its own elastic force, and the release spring 41 separates from the overvoltage protection element 2 under its own elastic force, thereby disconnecting the circuit, preventing the fault current from continuing to pass, and effectively protecting the load device.
[0036] Furthermore, the first elastic element 33 is in an energy-storing state before the pin of the first disengagement spring 31 and the first overvoltage protection element 1 is disconnected, and after the first disengagement spring 31 and the first overvoltage protection element 1 are separated, it pushes the first arc-shielding element 32 to move between the first disengagement spring 31 and the first overvoltage protection element 1 to provide electrical isolation. Similarly, the second elastic element 43 is in an energy-storing state before the pin of the second disengagement spring 41 and the second overvoltage protection element 2 is disconnected, and after the second disengagement spring 41 and the first overvoltage protection element 2 are disconnected, it pushes the first arc-shielding element 32 to move to provide electrical isolation between the first disengagement spring 31 and the first overvoltage protection element 2. After separation, the arc-shielding element 42 is moved to the pin between the release spring 41 and the overvoltage protection element 2 for electrical isolation. Specifically, the elastic element 33 and the elastic element 43 are springs. The elastic element 33 is connected between the arc-shielding element 32 and the main body 5, and the elastic element 43 is connected between the arc-shielding element 42 and the main body 5. When tripping occurs, the elastic element 33 and the elastic element 43 release their elastic force to push the arc-shielding element 32 and the arc-shielding element 42 to move respectively, effectively extinguishing the arc and improving the electrical isolation effect. In this embodiment, when a trip occurs, the release spring 31 separates from the pin of the overvoltage protection element 1 in the stacking direction, while the arc shield 32 moves perpendicular to the stacking direction to effectively separate the release spring 31 from the overvoltage protection element 1. Similarly, when a trip occurs, the release spring 41 separates from the pin of the overvoltage protection element 2 in the stacking direction, while the arc shield 42 moves perpendicular to the stacking direction to effectively separate the release spring 41 from the overvoltage protection element 2.
[0037] In this embodiment, the first release spring 31 and the second release spring 41 are distributed on two opposite sides of the main body 5, and both the first release spring 31 and the second release spring 41 are connected to the first electrode 61, thus designing the first release spring 31 and the second release spring 41 as an integral structure. In other words, the first release spring 31 and the second release spring 41 are integrally formed from a single elastic sheet. The elastic sheet is U-shaped, with one end forming the first release spring 31 and the other end forming the second release spring 41. The middle part of the U-shaped elastic sheet is connected to the first electrode 61. The structure is compact, with few parts, and easy to assemble and process.
[0038] The surge protector is a pluggable module that is plugged into a slot on the cabinet base. The surge protector also includes a housing 7, in which the core assembly is installed. The housing 7 conforms to the structural dimensions of a 1U device and is rectangular in shape. One end is a plug-in end 71, which is inserted into the slot for electrical connection with the base. The other end is an operating end 72, used to hold the surge protector for plugging and unplugging operations. The plug-in end is provided with a plug interface, which is provided with pins 74 that are electrically connected to electrodes 61, 62, and 63 respectively. The pins 74 are specifically metal spring clips, which facilitate plugging and unplugging while ensuring reliable electrical connection. The metal spring clips can reliably and elastically hold the electrode pins on the base, thereby ensuring the stability of the electrical connection.
[0039] A status indication mechanism is provided on the outer casing 7. The status indication mechanism includes a linkage component 81, a status indication part 82, and an indication window 83 on the outer casing 7 that cooperates with the status indication part 82. Arc shielding component 1 32 and arc shielding component 2 42 drive the status indication part 82 to switch states through the linkage component. The linkage component includes multi-stage sequentially driven linkage components. When either tripping mechanism 1 or tripping mechanism 2 trips, the status indication part 82 is driven to switch states through the linkage component. That is, arc shielding component 1 32 and arc shielding component 2 42 drive the same status indication part 82 to switch states through the same linkage component. Only one linkage component and one status indication part 82 are provided, resulting in fewer components, a compact structure, and reduced volume. When either arc shielding component 1 32 or arc shielding component 2 42 is activated, the same status indication mechanism is activated. Specifically, the status indication part 82 may include two different colored blocks. When the status indication part 82 moves, different colors are displayed in the indication window 83, thereby allowing for intuitive understanding of the working status of the surge protector through the status indication mechanism. In this embodiment, the linkage assembly includes a primary linkage and a secondary linkage, which are rotatably mounted on the outer casing 7. Both the primary and secondary linkages are rotating rods rotatably connected to the outer casing at their center. The primary linkage is driven to rotate by arc-shielding components 32 and 42. When either the first or second tripping mechanism trips, it drives the primary linkage to rotate. The secondary linkage is driven to rotate by the primary linkage. The status indicator 82 is mounted on the secondary linkage. A torsion spring for reset is also provided between the primary and secondary linkages and the outer casing, facilitating reset of the status indicator mechanism when replacing the movement assembly after tripping. The aforementioned status indicator mechanism has a simple and compact structure, is easy to implement, and employs a multi-stage transmission method, which extends the transmission distance and ensures transmission reliability, thereby guaranteeing the accuracy of the status indication.
[0040] The surge protector is also equipped with a remote signaling component 84, which is disposed in the housing 7. The arc-shielding element 32 and the arc-shielding element 42 touch the same remote signaling component 84. That is, when either the tripping mechanism 1 or the tripping mechanism 2 trips, they both touch the same remote signaling component 84 to send a remote signaling signal. The remote signaling component 84 includes a micro switch, a PCB board, and pin terminals. The micro switch and the pin terminals are disposed on the PCB board. The micro switch is touched by the arc-shielding element 32 and the arc-shielding element 42. The pin terminals are disposed in the plug-in interface on the plug-in end of the housing 7. While the first electrode 61, the second electrode 62, and the third electrode 63 are electrically connected to the base through the pin portion, the pin terminals are also connected to the corresponding electrode pins on the base. While the surge protector performs its protection function, the remote signaling component 84 monitors the working status of the surge protector in real time.
[0041] In this embodiment, electrode 62 is connected to both a pin portion 74 for connection with the base and an external port 9. Electrode 62 is used for grounding, and the external port 9 is used for external grounding. The external port 9 is located at the operating end of the housing 7 for convenient external wiring. The external port 9 specifically includes a conductive part 91, an elastic crimping member 92, and a pushing member 93. The conductive part 91 is electrically connected to electrode 62. The elastic crimping member 92 elastically abuts against the conductive part 91 to clamp the terminal inserted between the conductive part 91 and the elastic crimping member 92. The pushing member 93 adjustably abuts against the elastic crimping member 92 to adjust the elastic force applied by the elastic crimping member 92. Specifically, the conductive part 91 is an extension of electrode 62, resulting in a compact structure with fewer parts, improving the reliability of the electrical connection. The elastic crimping member 92 is formed by bending a metal strip. The metal strip has a rotating part that is bent into an arc shape in the middle. The elastic pressing member 92 is rotatably mounted on a pin on the outer shell 7 through the rotating part. One end of the metal strip abuts against the conductive part 91, and the other end of the metal strip is pressed by the pushing member 93. The pushing member 93 is specifically a bolt that is screwed onto the outer shell 7. The degree of pressing of the pushing member 93 against the elastic pressing member 92 is adjusted by turning the pushing member 93, so that the elastic pressing member 92 rotates around the pin on the outer shell 7 to adjust the elastic force of the elastic pressing member 92 against the conductive part 91. This allows for convenient wiring and ensures a reliable electrical connection.
