Specific embodiments

[0031] Embodiment 1:

[0032] Please refer to Figures 1 to 2 , an embodiment of the present invention provides a surge protection module. The surge protection module includes a protection module body 1. The protection module body 1 includes a housing 101, an energy storage rotating unit 102 rotatably arranged inside the housing 101, conductive sheets 103 fixedly fitted on both sides of the housing 101, and a limit assembly 2. The limit assembly 2 is in left-right sliding fit with the housing 101 and corresponds to the left-right position of the energy storage rotating unit 102. The right side of the limit assembly 2 is flush with the right side wall of the housing 101.

[0033] Among them, the energy storage rotating unit 102 and the housing 101 can play a role in reminding by color change, reminding the staff whether the surge protection module fails; the conductive sheet 103 is used to achieve electrical conduction after being assembled with the surge base 3. Other structures belonging to the protection module body 1, such as lightning protection chips, are not shown in this embodiment. When encountering overvoltage / current, the protection module body 1 can achieve automatic conduction, so that the energy storage rotating unit 102 is released from the limit and automatically rotates to the right. The protection module body 1, the housing 101, the conductive sheet 103, and the energy storage rotating unit 102 are all existing mature technologies and will not be described in detail here.

[0034] Please refer to Figures 2 to 3, in this embodiment, preferably: the limit component 2 includes a guide post 201 that is slidably engaged with the right inner wall of the housing 101 in the left-right direction. The left side of the guide post 201 corresponds to the extreme position after the energy storage rotating unit 102 rotates to the right, that is, after the energy storage rotating unit 102 finishes rotating to the right, it can just fit with the guide post 201, and its right side is flush with the right side wall of the housing 101; a first spring 202 is fixedly installed between the guide post 201 and the right inner wall of the housing 101. When the guide post 201 moves to the right, the first spring 202 can be used for its reset, and at the same time, the first spring 202 can realize the pre-positioning of the right end of the guide post 201 relative to the right side wall of the housing 101.

[0035] During normal use, there is a certain distance between the energy storage rotating unit 102 and the right guide post 201. When overvoltage / overcurrent occurs, the energy storage rotating unit 102 is released from the limit and rotates to the right. At this time, the surge protection module is in a failure state; during this process, the guide post 201 does not move, and the energy storage rotating unit 102 will not drive it to move.

[0036] Through the flush design of the guide post 201 and the right side wall of the housing 101, the appearance of this surge protection module is the same as that of other surge protection modules on the market, and they can be replaced and used interchangeably, with a wider application range.

[0037] Embodiment Two:

[0038] Please refer to Figures 1 to 4 , on the basis of Embodiment One, the embodiment of the present invention provides a surge protection device, which is mainly used to firmly limit the protection module body 1 after installation. The surge protection device includes a surge base 3 and the surge protection module in Embodiment One. A placement groove 301 for placing the housing 101 and a card slot 302 for placing the conductive sheet 103 are formed on the surge base 3. During assembly, the housing 101 is from top to bottom, and the conductive sheet 103 is aligned with the card slot 302 and inserted downward. Among them, when the surge base 3 is assembled with the protection module through the placement groove 301 and the wiring is connected, the electrical conduction preparation of the surge protection device can be realized. The wiring terminals corresponding to the conductive sheet 103 in the surge base 3 are not shown in the figure; at the same time, in this embodiment, one surge base 3 can be correspondingly assembled with four surge protection modules, and the four surge protection modules are arranged in a fitting manner, with the same appearance as other surge protection devices on the market, and they can be replaced and used interchangeably. This is an existing mature technology and will not be described in detail here.

[0039] A sliding component 5 is installed through and slidably on the inner right wall of the surge base 3, corresponding to the guide post 201 in the front-rear position. The sliding component 5 also extends into the interior of the placement groove 301. When the housing 101 is assembled downward, the side wall of the housing 101 squeezes the sliding component 5 to make it retract into the interior of the surge base 3. When the housing 101 descends to a position where the guide post 201 corresponds to the sliding component 5, the sliding component 5 extends out towards the placement groove 301 and contacts the guide post 201. Since there are four surge protection modules, four sliding components 5 are correspondingly provided.

[0040] Please refer to Figures 4 to 5 , in this embodiment, preferably: The sliding component 5 includes a slide bar 501 that penetrates the surge base 3 and is slidably engaged with it in the left-right direction. The slide bar 501 is circular in design. When the housing 101 and the surge base 3 are assembled, the left end of the slide bar 501 corresponds to the right end of the guide post 201, and its left end is arc-shaped; A second spring 503 is fixedly installed between the right end of the slide bar 501 and the inner wall of the surge base 3. When the housing 101 squeezes the arc-shaped left end of the slide bar 501, it drives the slide bar 501 to move rightward and squeeze the second spring 503; In the initial state, under the action of the second spring 503, the slide bar 501 can extend out of the placement groove 301 by a certain distance, and this distance is equal to the wall thickness of the right side wall of the housing 101.

[0041] During use, align the conductive sheet 103 with the card slot 302, and insert the housing 101 into the placement groove 301 from top to bottom to realize the connection between the protection module and the surge base 3; During this process, the right side wall of the housing 101 squeezes the arc-shaped left end of the slide bar 501, causing the slide bar 501 to move rightward and squeeze the second spring 503. As the housing 101 continues to descend, the guide post 201 and the slide bar 501 are in corresponding positions. At this time, the slide bar 501 automatically moves leftward under the action of the second spring 503, extends out of the surge base 3 and enters the interior of the housing 101. At this time, the left end of the slide bar 501 pushes the guide post 201, causing it to move leftward by a certain distance and stretch the first spring 202. This is the normal use state.

[0042] When overvoltage / current is encountered, the energy storage rotation unit 102 releases the limit and rotates to the right. Because the guide post 201 has moved leftward by a certain distance, the guide post 201 has deviated to the left from the rotation limit of the energy storage rotation unit 102. At this time, the energy storage rotation unit 102 pushes the guide post 201, driving the guide post 201 to move rightward so that its right end returns to be flush with the right side wall; During this process, the guide post 201 pushes the slide bar 501 to move synchronously so that the left end of the slide bar 501 is flush with the inner right wall of the surge base 3 (i.e., the slide bar 501 retracts into the interior of the surge base 3). At this time, the staff can remove the (failed) surge protection module and replace it, while the other effective surge protection modules remain unchanged.

[0043] Through the coordination of the guide post 201, the slider, the first spring 202, and the second spring 503, the surge protection module can be effectively limited so that it can be securely mounted on the surge base 3. At the same time, for a failed surge protection module, the limit can be automatically released, allowing the surge protection module at that location to be quickly replaced, while other valid surge protection modules remain stable, preventing staff from wasting time by mistakenly removing them. Overall work efficiency is improved, and the stability of the surge protection module and the surge base 3 ensures the overall protection effect. Furthermore, the overall structure is more concise, and whether the surge protection module is fixed is controlled by whether it fails, and multiple surge protection modules are arranged in a close-fitting manner, reducing the overall space occupied by the surge protection device, facilitating subsequent wiring design, and improving space utilization. Furthermore, the appearance is consistent with surge protection modules and surge protection devices on the market, allowing for free interchangeability and greater applicability.

[0044] Embodiment three:

[0045] See also Figures 1 to 4 On the basis of the second embodiment, a groove is provided at the end of the slide bar 501 close to the guide column 201, and a rotating component 6 is provided inside the groove, which protrudes a short distance relative to the left end of the slide bar 501. When the shell 101 is assembled downward, the rotating component 6 can contact the right side wall of the shell 101.

[0046] A slide groove 303 connected to the card slot 302 is provided on the surface of the surge base 3. An adjustment component 7 is slidably installed inside the slide groove 303 and moves synchronously with the rotating component 6 and extends into the card slot 302. When the slide rod 501 drives the rotating component 6 to move relative to the shell 101, the rotating component 6 can drive the adjustment component 7 to move synchronously, and at the same time, the adjustment component 7 can limit the rotating component 6.

[0047] See also Figures 4 to 7 In this embodiment, preferably, the rotating component 6 includes a short rod 602 that passes through the sliding rod 501 and is rotatably connected thereto, and the short rod 602 passes through the sliding rod 501 from front to back; a coil spring is sleeved on the outer surface of the short rod 602, and a roller 601 arranged inside the groove is fixedly installed at the front end of the short rod 602, and a small portion of the left side of the roller 601 protrudes relative to the left end of the sliding rod 501; a rib 603 that is movably fitted with the adjusting component 7 is fixedly installed on the outer surface of the short rod 602 and located at the rear side. In this embodiment, three ribs 603 are provided and arranged in a circular array.

[0048] In the above structure, the disc spring causes the short rod 602 and the roller 601 to tend to rotate counterclockwise, while the short rod 602 cannot rotate temporarily under the action of the adjusting assembly 7. When the short rod 602 and the roller 601 come into contact with the limit, they can automatically rotate counterclockwise. When the right side wall of the housing 101 rises and contacts the roller 601, it can drive the roller 601 to rotate clockwise to reset and complete energy storage.

[0049] The adjusting assembly 7 includes a sleeve 701 that is slidably engaged with the chute 303 in the front-back, left-right directions. The sleeve 701 cannot rotate along the chute 303 and its rear end is designed to be arc-shaped. It can be designed with special shapes such as triangular, quadrilateral, pentagonal, etc., but not circular. In this embodiment, the sleeve 701 is designed in a quadrilateral shape, and its arc-shaped rear end protrudes and extends into the inside of the card slot 302. The sleeve 701 is sleeved on the outer surface of the short rod 602 and the inner wall thereof is movably attached to the surface of the rib 603 away from the short rod 602. A convex block 704 that is movably attached to the side surface of the rib 603 is fixedly installed inside the sleeve 701. In this embodiment, three convex blocks 704 are provided and arranged in a circular array. The convex blocks 704 are in one-to-one fit with the rib 603, which can realize the rotational limit of the rib 603 and the short rod 602. At the same time, the short rod 602 and the sleeve 701 can realize synchronous left-right movement along the chute 303 through the rib 603 and the convex block 704. A side plate 702 is fixedly installed on the right side wall of the sleeve 701, and a third spring 703 is fixedly installed between the side plate 702 and the inner wall of the surge base 3 for automatic reset after the movement of the side plate 702 and the sleeve 701.

[0050] In the above structure, the front side of the rib 603 and the right side of the convex block 704 are also designed to be arc-shaped. At the same time, the length of the rib 603 in the front-back direction is greater than that of the convex block 704, so that the convex block 704 can quickly separate from the rib 603 when moving towards the short rod 602 along with the sleeve 701. At the same time, when the sleeve 701 drives the convex block 704 to reset away from the short rod 602, the convex block 704 can quickly fit with the side surface of the rib 603 under the action of the arc-shaped design to play a blocking role. In order to enable the convex block 704 to fit with the side surface of the rib 603 after reset, the thicknesses of both the convex block 704 and the rib 603 are set to be relatively small. In this embodiment, both are one centimeter.

[0051] To achieve the front-back, left-right sliding fit of the sleeve 701 relative to the chute 303, the up-down dimension of the chute 303 is adapted to the sleeve 701, and at the same time its left-right width is greater than that of the sleeve 701. To ensure that when the conductive sheet 103 moves within the card slot 302, the arc-shaped rear end of the sleeve 701 can be quickly adjusted, the chute 303 and the sleeve 701 are moved up to a higher position, and at the same time the positions of the sliding rod 501 and the guide post 201 can be synchronously moved up. To ensure that after the conductive sheet 103 has descended completely, the arc-shaped rear end of the sleeve 701 can still be limited, the chute 303 is designed to be within the up-down movement area of the conductive sheet 103, that is, when the conductive sheet 103 descends and after it has descended, it is in the overlapping area with the conductive sheet 103. At this time, the movement of the sleeve 701 towards the short rod 602 can be maintained.

[0052] To achieve better contact between the roller 601 and the side wall of the housing 101, a frosted strip is installed on the right side wall of the housing 101 and above the guide post 201, which can not only improve the frictional contact force between the roller 601 and the housing 101, but also enable the staff to better hold the housing 101.

[0053] During use, align the conductive sheet 103 with the card slot 302 and then insert the housing 101 downward to realize the connection between the protection module and the surge base 3. During this process, when the conductive sheet 103 is inserted into the card slot 302, it contacts the arc-shaped rear end of the sleeve 701, and the front surface of the conductive sheet 103 squeezes the sleeve 701 to move it towards the short rod 602. The sleeve 701 drives the convex block 704 to move synchronously, causing the convex block 704 to separate from the rib 603. At this time, the rib 603, the short rod 602, and the roller 601 are released from the limit and tend to rotate counterclockwise under the action of the disc spring; when the conductive sheet 103 is inserted into the card slot 302, the housing 101 has also entered the placement groove 301. At this time, the right side wall of the housing 101 starts to contact, causing the sliding rod 501 and the roller 601 to move to the right. Due to the contact between the right side wall of the housing 101 and the roller 601, and the cooperation of the counterclockwise rotating roller 601, the housing 101 can quickly descend and reach the bottom limit position; when the housing 101 descends to the bottom of the placement groove 301 (bottom limit position), the guide post 201 also corresponds to the position of the sliding rod 501. At this time, the sliding rod 501 and the roller 601 move to the left and push the guide post 201 to move it to the left by a certain distance. At this time, the conductive sheet 103 also descends to the limit position and still remains in contact with the sleeve 701. This is the normal use state.

[0054] When overvoltage / current is encountered, the energy storage rotating unit 102 is released from the limit and drives the guide post 201 to return to be flush with the right side wall; during this process, the guide post 201 pushes the sliding rod 501 and the roller 601 to move synchronously and separate from the housing 101. At this time, the staff can remove and replace the failed surge protection module.

[0055] In the second embodiment, it is necessary to press the top of the housing 101 by hand and press the surge protection module in the direction of the placement groove 301 until the end to complete the overall assembly. However, when encountering a narrow space or being blocked by other components (such as when there is a component with a height higher than that of the surge protection module on the front side of the surge base 3), it will affect the pressing of the surge protection module onto the surge base 3, that is, the surge protection module cannot be pressed to the bottom of the placement groove 301, resulting in certain limitations in use. Compared with the second embodiment, through the cooperation of structures such as the conductive sheet 103, the sleeve 701, the rib 603, and the disc spring, during assembly, it only needs to move a short distance in the direction of the placement groove 301 by aligning with the card slot 302, so that the roller 601 is released from the limit and rotates counterclockwise, driving the surge protection module to quickly drop to the limit position, without the need for the staff to keep pressing it by hand to the bottom of the placement groove 301, and it can also be normally applied when encountering a narrow space or being blocked; at the same time, combined with the movement of the conductive sheet 103 and the movement of the housing 101, the applicability is stronger.

[0056] Embodiment 4:

[0057] Please refer to Figures 1 to 8 , on the basis of the third embodiment, a jacking assembly 8 fixedly connected to the sliding rod 501 is installed through and slidably on the inner bottom wall of the surge base 3. When the sliding rod 501 moves leftward, the jacking assembly 8 can be driven to hide in the surge base 3, and when the sliding rod 501 moves rightward and resets, the jacking assembly 8 can be driven to rise to jack up the surge protection module. In this embodiment, corresponding to four surge protection modules, there are also four jacking assemblies 8.

[0058] In order to distinguish between the failed surge protection module and the effective surge protection module, that is, to make the failed surge protection module rise while effectively keeping the assembly stationary, a wedge-shaped groove 502 is formed on the surface of the sliding rod 501, and a control assembly 4 corresponding to the position of the wedge-shaped groove 502 and arranged in a staggered manner with the sliding rod 501 is installed through and slidably on the top of the surge base 3.

[0059] Please refer to Figures 9 to 10 , in this embodiment, preferably: the jacking assembly 8 includes a top block 801 that penetrates and is slidably engaged with the inner bottom wall of the surge base 3 and two guide wheels 802 rotatably installed inside the surge base 3. A fourth spring 803 is fixedly installed between the bottom of the top block 801 and the surge base 3 for resetting the top block 801 after it descends; a pulling rope 804 fixedly connected to the sliding rod 501 is fixedly installed at the bottom of the top block 801, and the pulling rope 804 passes around the two guide wheels 802 through the top block 801 and is fixedly connected to the sliding rod 501.

[0060] The control component 4 includes a button that penetrates through the top of the surge base 3 and is slidably engaged with it up and down. The bottom of the button extends into the interior of the surge base 3 and is fixedly installed with a long rod 401. At the bottom of the long rod 401, four wedge-shaped rods 402 corresponding to the positions of the four wedge-shaped grooves 502 are fixedly installed. In the initial state, the wedge-shaped rods 402 and the sliding rod 501 are arranged in a left-right misalignment, that is, in the initial state, the sliding rod 501 protrudes leftward relative to the surge base 3 under the action of the second spring 503. At this time, the right end of the sliding rod 501 is located on the left side of the wedge-shaped rod 402 and is in a left-right misalignment state with the wedge-shaped rod 402. When the sliding rod 501 is reset and moves rightward into the surge base 3 under the action of the guide post 201, the wedge-shaped groove 502 of the sliding rod 501 corresponds to the wedge-shaped rod 402 in the up-down position. A fifth spring 403 is fixedly installed between the top of the long rod 401 and the surge base 3 for resetting the long rod 401 and the button after they are pressed down.

[0061] In the above structure, the inclination directions of both the wedge-shaped rod 402 and the wedge-shaped groove 502 are diagonally upward to the right ( Figure 9 viewing angle), so that when the wedge-shaped rod 402 is pressed down, the sliding rod 501 can be driven to move rightward through the wedge-shaped groove 502.

[0062] During use, first, the surge protection module is assembled with the surge base, so that the sliding rod 501 moves toward the surge protection module, and through the cooperation of structures such as the roller 601, the housing 101, the short rod 602, and the sliding rod 501, the surge protection module is driven to quickly descend in place. The movement process and effect of the surge protection module are the same as those in Embodiment 3 and will not be repeated here; when the sliding rod 501 moves leftward, the wedge-shaped groove 502 and the wedge-shaped rod 402 will also change from the up-down corresponding state to the left-right misalignment state; when the sliding rod 501 moves leftward, it also drives the pull rope 804 to move synchronously. The pull rope 804 drives the top block 801 to descend and compress the fourth spring 803 through the cooperation of the guide wheel 802, so that the top block 801 is hidden inside the surge base. At this time, the bottom of the housing 101 can also be completely attached to the bottom groove wall of the placement groove 301, which is the normal use state.

[0063] When overvoltage / current is encountered, the energy storage rotation unit 102 drives the sliding rod 501, the wedge-shaped groove 502, and the pull rope 804 to move rightward and reset through the guide post 201; during this process, the wedge-shaped groove 502 returns to the up-down corresponding state with the wedge-shaped rod 402, and the pull rope 804 cooperates with the guide wheel 802 and the fourth spring 803 to drive the top block 801 to rise and reset. At this time, the top block 801 can lift the surge protection module by a certain distance; when the surge protection module rises, the right side wall of the housing 101 drives the roller 601 to rotate clockwise, and the energy storage of the roller 601 is realized through the disc spring, and driving the surge protection module to rise through the top block 801 does not need to consider the reaction force during the energy storage of the disc spring.

[0064] At this time, pressing the button downward drives the long rod 401 and the wedge-shaped rod 402 to descend vertically, and the wedge-shaped rod 402 continues to move rightward through the wedge-shaped slot 502, so that the pull rope 804 continues to be released, and the pull rope 804 cooperates with the guide wheel 802 and the fourth spring 803 to allow the top block 801 to continue to rise, and the top block 801 allows the surge protection module to continue to rise until it is raised to a state where it is about to be separated from the placement slot 301 (which is also the state where the conductive sheet 103 is about to be separated from the card slot 302), that is, the surge protection module is separated from the surge base 3; in this process, because the push The block is lifted without considering the reaction force of the coil spring when storing energy. At the same time, after rising, the housing 101 can drive the roller 601 to rotate clockwise to complete the final energy storage. Because the conductive sheet 103 is about to leave the slot 302, it has also separated from the sleeve 701. Under the action of the side plate 702 and the third spring 703, the sleeve 701 drives the protrusion 704 to move away from the short rod 602. The arc design drives the protrusion 704 to resume contact with the rib 603, realizing the rotation limit of the rib 603, the short rod 602 and the roller 601. At this time, the staff only needs to hold the two sides of the surge protection module and gently lift it to complete the quick disassembly of the surge protection module.

[0065] In the third embodiment, although the surge protection module is quickly assembled in the placement slot 301 through the cooperation of structures such as the short rod 602, the coil spring, the roller 601 and the slide rod 501, when removing the surge protection module, it is necessary to overcome the reaction force of the coil spring energy storage. At the same time, when removing the failed surge protection module, the staff still needs to observe and determine whether the surge protection module has failed in advance, which is more difficult to accomplish in a small space or when there is an obstruction, and there are certain limitations in use. Compared with the third embodiment, through the cooperation of structures such as the slide bar 501, the wedge rod 402, the top block 801 and the pull rope 804, on the basis of realizing the rapid assembly of the surge protection module, when the surge protection module fails, it can be automatically raised a certain distance, so that the failed surge protection module can be clearly distinguished from the effective one, and at the same time, a part of the reaction force of the energy storage of the coil spring can be overcome; on this basis, the wedge rod 402 can be used to make the failed surge protection module further move to a state where it is about to be separated from the surge base 3, so that the staff can easily remove the failed surge protection module. In this process, there is no need to consider the reaction force of the energy storage of the coil spring, and the coil spring and the roller 601 are fully energized, ready for the rapid assembly of the new surge protection module; the overall process can also be normally applied when encountering a small space or an obstruction, and combined with the movement of the slide bar 501 and the use of the roller 601, more requirements in actual use are met.

[0066] As a further improvement of this embodiment: during actual use, a control component 4 can be additionally installed on the basis of the original control component 4. The new control component 4 is located between the original control component 4 and the surge protection module, and the new control component 4 is vertically corresponding to the position where the slide bar 501 and the wedge-shaped groove 502 protrude leftward relative to the surge base 3. At this time, the new button, long rod 401 and wedge-shaped rod 402 are located in the middle of the original button, long rod 401 and wedge-shaped rod 402, and the new wedge-shaped rod 402 is vertically corresponding to the wedge-shaped groove 502 after the slide bar 501 moves leftward.

[0067] When the new button is pressed, it can drive the new wedge-shaped rod 402 to descend. The new wedge-shaped rod 402 drives the slide bar 501 to move rightward and reset and release the pull rope 804 through the wedge-shaped groove 502 on the slide bar 501 that has not moved rightward and reset. At this time, all the surge protection modules are released from the limit and automatically rise a certain distance, and all the slide bars 501 thereof move rightward to the same position. Then press the original button to drive the original wedge-shaped rod 402 to descend. The original wedge-shaped rod 402 drives the slide bar 501 to continue to move rightward and continue to release the pull rope 804 through the wedge-shaped groove 502 on the slide bar 501 after it moves rightward, which can achieve the effect of further improving the surge protection module described in the fourth embodiment, and all the surge protection modules are improved, which is applicable to the comprehensive inspection and replacement of all the surge protection modules.
