Description

Technical Field

[0001] This utility model relates to the field of electronic components, and more specifically to a frame-type power surge protector. Background Technology

[0002] Surge protection devices (SPDs) are used to absorb lightning overvoltage spikes, filter out interference signals in the power grid, and protect system safety. They are widely used in precision and expensive instruments, equipment, and power systems in military, new energy, communication base stations, railways, and meteorological systems to protect instruments and equipment from lightning strikes and other transient overvoltage interference. As the height of power supply enclosures in the communication market continues to decrease, the existing SPD structures—35mm standard rail mount, PCB board mount, and screw mount—pose significant challenges to installation and maintenance due to their height, footprint, and wiring requirements. Furthermore, the investment cost of the SPD and its effective control circuitry cannot be readily observed. Once an SPD deteriorates or fails, it requires disconnecting the power supply, opening the cover, loosening multiple screws, or removing the SPD from the PCB board with a soldering iron, making repair and replacement inconvenient.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Figures 1A to 5C Taking this example, we will introduce in detail the frame-type power surge protector provided in the embodiments of this utility model.

[0039] The frame-type surge protector provided in this embodiment mainly includes: a housing, a lightning protection component 16, a clamping component, a fixing frame 19, and a rotating wheel 20.

[0040] Specifically, a pull knob 3 and a latch 2 are provided on one side of the casing. The casing can be inserted into or removed from the chassis by using the combination of the pull knob 3 and the latch 2. The surge protection component 16, without changing its size, can install one to three parallel varistor chips, or it can install switching components, such as discharge tubes, graphite gaps, etc. The nominal discharge current In can cover the commonly used 10kA, 20kA, 30kA, 40kA and 60kA, and the corresponding maximum discharge current values ​​can reach 20kA, 40kA, 60kA, 80kA and 100kA, achieving lightning protection levels of C, B and B+C. Furthermore, the surge protection component 16 is positioned and installed in the fixing frame 19. One output terminal of the surge protection component 16 is connected to the first clamping component through a connecting electrode, and the other output terminal is connected to the second clamping component through a remote signaling terminal. The output end of the first clamping assembly is secured to the copper busbar led out from the protected equipment by the limiting of the housing. The input end of the remote signaling terminal is in contact with the micro switch 15, the lever 26 included in the micro switch 15, and the slider 17. The output end of the remote signaling terminal is connected to the second clamping assembly through a lead wire. The second clamping assembly also includes an isolator 24. When the surge protection assembly 16 is in normal condition, the lever 26 included in the micro switch 15 will contact the contact point included in the micro switch 15 under the action of the slider 17, thereby keeping the remote signaling terminal in a normally closed state. When the surge protection assembly 16 deteriorates or is about to fail, the slider 17 will move in the opposite direction of the micro switch. After the slider 17 moves, the lever 26, which is in contact with the contact point of the micro switch 15, will slide in the direction of the slider's movement, disconnecting from the contact point of the micro switch 15, thereby realizing the conversion of the remote signaling terminal from normally closed to normally open, achieving the alarm function.

[0041] In practical applications, a micro switch is a contact mechanism with tiny contact intervals and a quick-acting mechanism that performs switching actions with a specified stroke and force. It plays a role in controlling the on / off state of a circuit. The remote signaling terminal is used to transmit remote signaling signals. In this embodiment, the remote signaling terminal of the micro switch is connected to the second clamping assembly via leads and a circuit board to transmit the status signal of the surge protection component for remote monitoring and other operations.

[0042] The mounting bracket 19 includes a first slot 32 and a first lug. A separation electrode 13 and a slider 17 including a second slot 33 and a second lug are disposed at the upper end of the mounting bracket 19. Specifically, the first slot 32 and the second slot 33 are the same size and are concentrically arranged. The separation electrode 13 is then placed in the first slot 32 and the second slot 33 and welded to the lightning protection component 16 with a warm alloy tin. The first lug and the second lug are used to set the tension spring 18. At this time, the separation electrode 13 also has another function, which is to fix the slider 17 including the second slot 33 on the mounting bracket 19. If the separation electrode 13 leaves the first slot 32, the slider 17 will move towards the first lug under the action of the tension spring 18.

[0043] In practical applications, when the surge protection component 16 deteriorates or is about to fail, the voltage limiting or switching voltage limiting element heats up. When the heat accumulates to a certain level, the detachment end of the separation electrode 13 located in the first slot 32 and the second slot 33 separates from the voltage limiting or switching voltage limiting element and lifts up. After the separation electrode 13 leaves the first slot 32, since the two second lugs and the two first lugs are respectively provided with two tension springs 18, the slider 17 will move towards the first lug under the action of the tension springs 18 until the separation electrode 13 is completely separated from the voltage limiting or switching voltage limiting element. Then, the shovel-shaped surface 31 located on the side of the second lug away from the first lug completely covers the first slot 32.

[0044] Furthermore, the rotating wheel 20 located on one side of the fixed frame 19 has a torsion spring 21 installed inside. One end of the rotating wheel 20 is an L-shaped end 27, which contacts the U-shaped groove of the slider 17. The second end of the rotating wheel 20 is a green end 30-1. When the slider 17 moves towards the first lug, the relative position of the L-shaped end and the U-shaped groove changes. Originally, the L-shaped end 27 was constrained and positioned within the U-shaped groove. With the movement of the slider 17 and the cooperation of the torsion spring 21, this constraint is broken, allowing the L-shaped end to loosen and enabling the rotating wheel 20 to rotate counterclockwise. The second end of the rotating wheel 20, originally green end 30-1, becomes red end 30-2 after counterclockwise rotation. This change in red end 30-2 can be observed through the observation window 25 on the outer casing, thus realizing a visual alarm function to alert the user that the surge protection component 16 may have a problem.

[0045] This utility model embodiment provides a frame-mounted surge protector. The pull-twist mechanism 3 and the snap-fit ​​mechanism 2, integrally designed on the housing, allow for the overall fixation of the housing to the chassis or cabinet. Furthermore, the design of the mounting bracket 19 not only enables the conversion of remote alarm signals but also allows for linkage with visual alarms, avoiding the alarm risks caused by asynchronous operation and improving alarm reliability. The torsion spring 21 drives the rotating wheel 20 to rotate, converting arc motion into linear motion, thus improving the alarm reliability of the indicator lights connected to the rotating wheel 20. The design of the first clamping component not only results in a refined appearance and a compact, simple structure but also allows for the clamping of copper busbars, simplifying installation and use. This surge protector embodiment solves the problem of existing SPD repairs requiring the loosening of multiple screws or the removal of the SPD from the PCB board with a soldering iron, leading to complex repair processes.

[0046] For example, this utility model embodiment provides a frame-type power surge protector, wherein the first clamping assembly includes a first clamping member 9 and a second clamping member 10; the second clamping assembly includes a third clamping member 11-1 and a fourth clamping member 11-2.

[0047] Specifically, the first clamping member 9 and the second clamping member 10 are electrically connected to the voltage limiting or switching voltage limiting element through the first connecting electrode 12 and the second connecting electrode 14, respectively; the first clamping member 9 and the second clamping member 10 can fasten the copper busbars led out from the protected equipment by the limiting of the outer shell, so as to achieve the function of pluggable and tight connection.

[0048] The third clamping member 11-1 and the fourth clamping member 11-2 are electrically connected to the micro switch 15 via the first remote signaling terminal and the second remote signaling terminal, respectively. An isolator 24 is provided between the third clamping member 11-1 and the fourth clamping member 11-2, and a lever 26 is provided between the micro switch 15 and the surge protection assembly 16. When the surge protection assembly 16 is in normal condition, the first remote signaling terminal and the second remote signaling terminal are normally closed. In other words, when the surge protection assembly 16 deteriorates or is about to fail, the voltage limiting element or the switching element heats up. When the heat accumulates to a certain level, the separating electrode 13 separates from the voltage limiting element or the switching element. At the same time, under the action of the tension spring 18, the slider 17 moves toward the first lug until the separating electrode 13 is completely separated from the voltage limiting element or the switching element. Then, the shovel-shaped surface 31 on the side of the second lug away from the first lug completely covers the first slot 32.

[0049] For example, this utility model embodiment provides a frame-type power surge protector. The pull knob 3 includes a first compression spring 22 and a first inclined end 28, and the buckle 2 includes a second inclined end 29 and a boss end. Specifically, the upper side of the first inclined end 28 contacts the lower side of the second inclined end 29, and the end of the first inclined end 28 facing the pull knob 3 is connected to the pull knob through the first compression spring 22. The bottom layer of the second inclined end 29 is fixedly connected to the boss end, and the upper side of the second inclined end 29 is connected to the fixing frame 19 through the second compression spring 23. In practical applications, when the pull-torque 3 moves away from the buckle under the action of external force, the pull-torque 3 moves parallel to the set track under the action of the first compression spring 22. The first inclined end 28, which is fixedly connected to the pull-torque 3, moves in the same direction as the pull-torque 3 under the action of the pull-torque 3. The second inclined end 29, which is located above the first inclined end 28, slides into the shell under the action of friction, causing the second compression spring 23 to contract. When the second inclined end 29 slides into the shell, it will drive the protrusion end of the buckle, which is fixedly connected to the second inclined end, to also move into the shell. In other words, the buckle 2 is a single integral component, the second inclined end 29 is a characteristic part of the buckle 2, and the boss end is also a characteristic component of the buckle 2. The second inclined end 29 cooperates with the first inclined end 28 on the pull knob 3. When the pull knob 3 is pulled, the interaction between the first inclined end 28 and the second inclined end 29 allows the boss end of the buckle 2 to extend and retract under the action of the second compression spring 23, thereby completing the fixing or loosening operation with the chassis or cabinet. In this embodiment, the integral design of the pull knob not only restricts the range of motion, but also enables the buckle to extend and retract freely with the assistance of the first and second compression springs, facilitating the insertion and removal of the product in the chassis or cabinet. The buckle utilizes friction and is linked with the pull knob, achieving free extension and retraction with the assistance of the first and second compression springs, thus playing an overall fixing role and simplifying operation.

[0050] Based on the above design, after the outer casing is inserted into place, pushing in the pull knob 3 will cause the latch 2 to extend again, achieving the function of fixing it to the chassis or cabinet. Based on the above design, it can also be combined into "1+1", "2P", "3+1", "4P" and other modes. When forming a combined mode, since the weak point of the plastic cross on the first outer casing 101 and the second outer casing 102 includes multiple slots, namely the first slot 401, the second slot 402, the third slot 501, the fourth slot 502, the fifth slot 601, the sixth slot 602, the seventh slot 701, and the eighth slot 702, it is necessary to remove the slots on the weak point of the cross located inside the combined mode, and only retain the slots on the outside of the combined mode. That is, whether it is a single power surge protector or a power surge protector in a combined mode, it only includes slots on both sides of the outer casing. In this embodiment of the utility model, the slots provided on both sides of the outer casing increase the electrical clearance and creepage distance to facilitate the insertion of the copper busbars led out from the protected equipment.

[0051] For example, in the combined mode, the remote signaling terminals of the micro switch 15 are connected to the third clamping member 11-1 and the fourth clamping member 11-2 by means of leads and circuit boards, passing through the removed first hole 401 and second hole 402; rivets pass through two or more fixing holes 8 located on the pull torque 3 to achieve overall riveting and unified pulling. In this embodiment, the individual units also need to have rivets passed through multiple corresponding holes in the first housing 101 and the second housing 102 to achieve fixed riveting, thereby achieving a reliable and stable lightning protection effect.

[0052] It should be noted that the frame-type surge protector provided in this embodiment of the invention also has a barcode label mounting frame on one side of the housing. This barcode label mounting frame is used to set barcodes, QR codes, or performance parameter tables. In practical applications, the design of the mounting frame for unique product tracking information such as barcodes, QR codes, and performance parameters reflects the product's aesthetic appeal and also facilitates product identification and management.

[0053] For example, this utility model embodiment provides a frame-type power surge protector, which also includes an observation window 25; the observation window 25 is located on the housing and is used to display a green end 30-1 when the separating electrode 13 is located in the first slot 32, and to display a red end 30-2 after the separating electrode 13 leaves the first slot 32.

[0054] The frame-mounted surge protector of this utility model embodiment utilizes a slider mounted on a fixed frame. One end of the slider can switch between remote signaling alarms, while the other end is linked with a visual alarm, avoiding the risk of false alarms caused by asynchrony between the two and improving the reliability of the alarm. This allows users to understand the status of the surge protection components in a timely and accurate manner. Furthermore, the fixed frame maximizes the parallel installation of multiple protection chips in a small volume, making full use of space and integrating more protection functions within a limited volume. At the same time, the mounting ears on the fixed frame and the mounting ears included in the slider are linked by a tension spring, resulting in a compact structure and coordinated functions. This frame-mounted surge protector solves the problem of existing surge protectors requiring the loosening of multiple screws or disassembly from the PCB board with a soldering iron during maintenance, which leads to complicated maintenance processes.
