DETAILED DESCRIPTION

[0034] Embodiment 1:

[0035] See also Figure 1 to Figure 2 An embodiment of the present invention provides a surge protection module, which includes a protection module body 1. The protection module body 1 includes a shell 101, an energy storage rotating unit 102 rotatably arranged inside the shell 101, a conductive sheet 103 fixedly engaged with both sides of the shell 101, and a limit assembly 2. The limit assembly 2 is slidably matched with the shell 101 and corresponds to the left and right positions of the energy storage rotating unit 102. The right side of the limit assembly 2 remains flush with the right side wall of the shell 101.

[0036] Among them, the energy storage rotating unit 102 cooperates with the shell 101 to play a color change reminder role, reminding the staff whether the surge protection module is invalid; the conductive sheet 103 is used to play the role of 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 also installed inside the shell 101, which are not shown in this embodiment. When encountering overvoltage / current, the protection module body 1 can be automatically turned on, so that the energy storage rotating unit 102 releases the limit and automatically rotates to the right. The protection module body 1, the shell 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.

[0037] See also Figures 2 to 3In this embodiment, preferably: the limit assembly 2 includes a guide column 201 that is slidably matched with the inner right wall of the shell 101, and the left side of the guide column 201 corresponds to the extreme position of the energy storage rotation unit 102 after rotating to the right, that is, the energy storage rotation unit 102 can just fit with the guide column 201 after the right rotation is completed, and its right side remains flush with the right side wall of the shell 101; a first spring 202 is fixedly installed between the guide column 201 and the inner right wall of the shell 101, and the first spring 202 can be used to reset the guide column 201 when it moves to the right, and at the same time, the first spring 202 can realize the pre-positioning of the right end of the guide column 201 relative to the right side wall of the shell 101.

[0038] During normal use, there is a certain distance between the energy storage rotating unit 102 and the right guide column 201. When encountering overvoltage / current, the energy storage rotating unit 102 releases the limit and rotates to the right. At this time, the surge protection module is in a failed state; during this process, the guide column 201 does not move, and the energy storage rotating unit 102 will not drive it to move.

[0039] The flush design of the guide post 201 and the right side wall of the housing 101 makes the surge protection module consistent in appearance with other surge protection modules on the market, and can be used interchangeably, so it has a wider range of applications.

[0040] Embodiment 2:

[0041] See also Figures 1 to 4 On the basis of the first embodiment, the embodiment of the present invention provides a surge protection device, which is mainly used to realize the firm limit of the protection module body 1 after it is installed. The surge protection device includes a surge base 3 and the surge protection module in the first embodiment. The surge base 3 is provided with a placement slot 301 for placing the housing 101 and a card slot 302 for placing the conductive sheet 103. When assembling, the housing 101 is inserted downwardly with the conductive sheet 103 aligned with the card slot 302 from top to bottom. Among them, when the surge base 3 is assembled with the protection module through the placement slot 301 and the wiring is coordinated, the electrical conduction preparation of the surge protection device can be realized. The surge base 3 is provided with a wiring terminal corresponding to the conductive sheet 103, which is not shown in the figure; at the same time, in this embodiment, one surge base 3 can be equipped with four surge protection modules, and the four surge protection modules are arranged in a close fit, which is consistent with the appearance of other surge protection devices on the market and can be used interchangeably. It is an existing mature technology and will not be described in detail here.

[0042] The inner right wall of the surge base 3 is penetrated and slidably mounted with a sliding assembly 5 corresponding to the front and rear positions of the guide pillar 201. The sliding assembly 5 also extends to the inside of the placement slot 301. When the housing 101 is assembled downward, the side wall of the housing 101 presses the sliding assembly 5 to make it retract into the inside of the surge base 3. When the housing 101 is lowered to the guide pillar 201 corresponding to the sliding assembly 5, the sliding assembly 5 extends toward the placement slot 301 and contacts the guide pillar 201. Because four surge protection modules are provided, four sliding assemblies 5 are also provided accordingly.

[0043] See also Figures 4 to 5 In this embodiment, preferably: the sliding assembly 5 includes a sliding rod 501 that penetrates the surge base 3 and slides therewith left and right, the sliding rod 501 is circular in design, and when the shell 101 and the surge base 3 are assembled, the left end of the sliding rod 501 corresponds to the right end of the guide column 201, and its left end is arc-shaped; a second spring 503 is fixedly installed between the right end of the sliding rod 501 and the inner wall of the surge base 3, and when the shell 101 squeezes the arc-shaped left end of the sliding rod 501, the sliding rod 501 is driven to move right to squeeze the second spring 503; in the initial state, the sliding rod 501 can be extended relatively to the placement slot 301 by a distance under the action of the second spring 503, and the distance is equal to the thickness of the right side wall of the shell 101.

[0044] When in use, align the conductive sheet 103 with the card slot 302, and insert the shell 101 from top to bottom into the placement slot 301 to achieve the connection between the protection module and the surge base 3; in this process, the right side wall of the shell 101 squeezes the arc-shaped left end of the slide bar 501, causing the slide bar 501 to move right and squeeze the second spring 503. As the shell 101 continues to descend, the guide column 201 and the slide bar 501 are in corresponding positions. At this time, the slide bar 501 automatically moves to the left under the action of the second spring 503, extends from the surge base 3 and enters the interior of the shell 101. At this time, the left end of the slide bar 501 pushes the guide column 201, causing it to move left a distance and stretch the first spring 202. This is a normal use state.

[0045] When encountering overvoltage / current, the energy storage rotating unit 102 releases the limit and rotates to the right. Because the guide column 201 moves to the left for a distance, the guide column 201 has deviated to the left from the rotation limit of the energy storage rotating unit 102. At this time, the energy storage rotating unit 102 pushes the guide column 201, driving the guide column 201 to move to the right so that its right end is restored to be flush with the right side wall; in this process, the guide column 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 (that is, the slide bar 501 is retracted into the interior of the surge base 3). At this time, the staff can remove the surge protection module (which has failed) and replace it, while other effective surge protection modules remain different.

[0046] Through the cooperation of the guide column 201, the slider, the first spring 202 and the second spring 503 and other structures, the surge protection module can be effectively limited so that it can be stably installed on the surge base 3; at the same time, for the failed surge protection module, the limit can be automatically released, and the surge protection module at this position can be quickly replaced, while other effective surge protection modules remain stable, avoiding the staff from wasting time by mistake, and the overall work efficiency is improved. In addition, because of the stable state of the surge protection module and the surge base 3, the overall protection effect can be guaranteed. At the same time, the overall structure is more concise, and whether the surge protection module is fixed is controlled by whether it is failed, and multiple surge protection modules are arranged in a close fit, which reduces the overall space occupied by the surge protection device, facilitates the later wire wiring design, and improves the space utilization rate; and the appearance is consistent with the surge protection modules and surge protection devices on the market, and can be freely exchanged and used, that is, it is more applicable.

[0047] Embodiment three:

[0048] 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.

[0049] 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 the adjustment component 7 can limit the rotating component 6.

[0050] 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 front to back; a disc 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 part 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.

[0051] In the above structure, the coil spring makes the short rod 602 and the roller 601 tend to rotate counterclockwise, but the short rod 602 cannot rotate temporarily under the action of the adjustment assembly 7. When the short rod 602 and the roller 601 contact the limit position, they can automatically rotate counterclockwise, and when the right side wall of the housing 101 rises and contacts the roller 601, it can drive it to rotate clockwise and reset to complete energy storage.

[0052] The adjusting assembly 7 includes a sleeve 701 that can slide forward, backward, left and right with the slide groove 303. The sleeve 701 cannot rotate along the slide groove 303 and its rear end is set to an arc shape. It can be a triangular, quadrilateral, pentagonal or other special-shaped design, but cannot be circular. In this embodiment, the sleeve 701 is designed in a quadrilateral shape, and its arc-shaped rear end protrudes and extends to the inside of the slot 302; the sleeve 701 is sleeved on the outer surface of the short rod 602 and its inner wall is movably fitted with the surface of the rib 603 away from the short rod 602, and a protrusion 704 that is movably fitted with the side of the rib 603 is fixedly installed inside the sleeve 701. In this embodiment, three protrusions 704 are provided and arranged in a ring array. The protrusions 704 are fitted one by one with the rib 603, which can realize the rotation 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 and right movement along the slide groove 303 through the rib 603 and the protrusion 704. A side plate 702 is fixedly mounted on the right side wall of the sleeve 701 , and a third spring 703 is fixedly mounted between the side plate 702 and the inner wall of the surge base 3 for automatically resetting the side plate 702 and the sleeve 701 after movement.

[0053] In the above structure, the front side of the rib 603 and the right side of the protrusion 704 are also designed in an arc shape, and the length of the rib 603 in the front-to-back direction is greater than the protrusion 704, so that the protrusion 704 can quickly separate from the rib 603 when the sleeve 701 moves toward the short rod 602; at the same time, when the sleeve 701 drives the protrusion 704 away from the short rod 602 to reset, the protrusion 704 can quickly fit with the side of the rib 603 under the effect of the arc design, playing a blocking role. In order to achieve that the protrusion 704 can fit with the side of the rib 603 after reset, the thickness of the protrusion 704 and the rib 603 are both set to be small, and in this embodiment, they are both one centimeter.

[0054] In order to achieve the front-back and left-right sliding fit of the sleeve 701 relative to the slide slot 303, the upper and lower dimensions of the slide slot 303 are adapted to the sleeve 701, and its left-right width is greater than the sleeve 701. In order to ensure that the arc-shaped rear end of the sleeve 701 can be quickly adjusted when the conductive sheet 103 moves in the slot 302, the slide slot 303 and the sleeve 701 are moved up to a higher position, and the positions of the slide bar 501 and the guide column 201 can also be moved up synchronously. In order to ensure that the arc-shaped rear end of the sleeve 701 can still be limited after the conductive sheet 103 is completely lowered, the slide slot 303 is designed to be within the upper and lower moving area of ​​the conductive sheet 103, that is, the conductive sheet 103 is in the overlapping area with the conductive sheet 103 when and after the conductive sheet 103 is lowered, and the movement of the sleeve 701 toward the short rod 602 can be maintained at this time.

[0055] In order to achieve better contact between the roller 601 and the side wall of the shell 101, a frosted strip is installed on the right side wall of the shell 101 and above the guide column 201, which can not only improve the friction contact force between the roller 601 and the shell 101, but also enable the staff to better pick up the shell 101.

[0056] When in use, align the conductive sheet 103 with the card slot 302 and then insert the housing 101 downward to achieve the connection between the protection module and the surge base 3. In this process, after 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 toward the short rod 602. The sleeve 701 drives the protrusion 704 to move synchronously so that the protrusion 704 is separated from the rib 603. At this time, the rib 603, the short rod 602 and the roller 601 are released from the limit, and they tend to rotate counterclockwise under the action of the coil spring; when the conductive sheet 103 is inserted into the card slot 302, the housing 101 has also entered the placement slot 301, and the right side wall of the housing 101 begins to contact The contact causes the slide bar 501 and the roller 601 to move to the right. Because the right side wall of the shell 101 is in contact with the roller 601, and with the counterclockwise rotation of the roller 601, the shell 101 can quickly drop and reach the bottom limit position; when the shell 101 drops to the bottom of the placement slot 301 (bottom limit position), the guide column 201 also corresponds to the position of the slide bar 501. At this time, the slide bar 501 and the roller 601 move to the left and push the guide column 201 to move it to the left for a distance. At this time, the conductive sheet 103 also drops to the limit position and still maintains contact with the sleeve 701. This is a normal usage state.

[0057] When encountering overvoltage / current, the energy storage rotating unit 102 releases the limit and drives the guide column 201 to return to being flush with the right side wall; during this process, the guide column 201 pushes the slide bar 501 and the roller 601 to move synchronously and separate from the shell 101. At this time, the staff can remove and replace the failed surge protection module.

[0058] In the second embodiment, it is necessary to press the top of the housing 101 by hand, press the surge protection module in the direction of the placement slot 301 and all the way to the bottom, and then the overall assembly is completed; however, when encountering a narrow space or when other components are blocked (such as when the front side of the surge base 3 is provided with a component higher than the height of the surge protection module), it will affect the pressing of the surge protection module to the surge base 3, that is, the surge protection module cannot be pressed to the bottom of the placement slot 301, and there are certain limitations in use. Compared with the second embodiment, through the cooperation of the conductive sheet 103, the sleeve 701, the rib 603 and the coil spring and other structures, during assembly, it is only necessary to align the card slot 302 and move a short distance in the direction of the placement slot 301, so that the roller 601 releases the limit and rotates counterclockwise, driving the surge protection module to quickly drop to the limit position, without the need for the staff to press it all the way to the bottom of the placement slot 301 by hand, and it can also be normally used when encountering a narrow space or when there is an obstruction; at the same time, combined with the movement of the conductive sheet 103 and the movement of the housing 101, the applicability is stronger.

[0059] Embodiment 4:

[0060] See also Figures 1 to 8 On the basis of the third embodiment, the inner bottom wall of the surge base 3 is penetrated and slidably installed with a lifting assembly 8 fixedly connected to the slide bar 501. When the slide bar 501 moves to the left, the lifting assembly 8 can be driven to hide in the surge base 3. When the slide bar 501 moves to the right to reset, the lifting assembly 8 can be driven to rise and lift up the surge protection module. In this embodiment, there are four surge protection modules, so there are also four lifting assemblies 8.

[0061] In order to distinguish between a failed surge protection module and an 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 opened on the surface of the slide bar 501, and a control component 4 corresponding to the position of the wedge-shaped groove 502 and offset from the slide bar 501 is penetrated and slidably installed on the top of the surge base 3.

[0062] See also Figures 9 and 10 In this embodiment, preferably: the lifting assembly 8 includes a top block 801 that penetrates the inner bottom wall of the surge base 3 and slides up and down therewith, and two guide wheels 802 rotatably installed inside the surge base 3, and a fourth spring 803 is fixedly installed between the bottom of the top block 801 and the surge base 3, which is used for resetting the top block 801 after it descends; a pull rope 804 fixedly connected to the slide bar 501 is fixedly installed at the bottom of the top block 801, and the pull rope 804 passes through the top block 801 and passes through the two guide wheels 802 in turn and is fixedly connected to the slide bar 501.

[0063] The control assembly 4 includes a button that penetrates the top of the surge base 3 and slides with it up and down. The bottom of the button extends to the inside of the surge base 3 and is fixedly installed with a long rod 401. The bottom of the long rod 401 is fixedly installed with four wedge-shaped rods 402 corresponding to the positions of the four wedge-shaped grooves 502. In the initial state, the wedge-shaped rods 402 and the slide bar 501 are arranged in a left-right misalignment, that is, in the initial state, the slide bar 501 protrudes to the left relative to the surge base 3 under the action of the second spring 503. At this time, the right end of the slide bar 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 slide bar 501 is reset and moved rightward into the surge base 3 under the action of the guide column 201, the wedge-shaped groove 502 of the slide bar 501 corresponds to the wedge-shaped rod 402 in the upper and lower positions. 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 being pressed down.

[0064] In the above structure, the inclination direction of the wedge rod 402 and the inclination direction of the wedge groove 502 are both inclined to the upper right ( Fig. 9 When the wedge-shaped rod 402 is pressed downward, the sliding rod 501 can be driven to move rightward through the wedge-shaped groove 502.

[0065] When in use, the surge protection module is first assembled with the surge base, so that the slide bar 501 moves toward the surge protection module, and the surge protection module is driven to quickly drop into place through the cooperation of the roller 601, the shell 101, the short rod 602 and the slide bar 501. The movement process and effect of the surge protection module are the same as those in the third embodiment, and are not repeated here; when the slide bar 501 moves to the left, it will also cause the wedge-shaped groove 502 and the wedge rod 402 to change from a corresponding state to a left-right misaligned state; when the slide bar 501 moves to the left, it also drives the pull rope 804 to move synchronously. The pull rope 804 drives the top block 801 to drop and squeeze 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 shell 101 can also be completely fitted with the bottom groove wall of the placement groove 301. This is a normal use state.

[0066] When encountering overvoltage / current, the energy storage rotating unit 102 drives the sliding rod 501, the wedge-shaped groove 502 and the pull rope 804 to move right and reset through the guide column 201; in this process, the wedge-shaped groove 502 returns to a state corresponding to the wedge-shaped rod 402 up and down, 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 for a distance; when the surge protection module rises, the right side wall of the shell 101 drives the roller 601 to rotate clockwise, and the energy storage of the roller 601 is realized by the coil spring, and when the surge protection module is driven to rise by the top block 801, there is no need to consider the reaction force of the coil spring when storing energy.

[0067] 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 groove 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 leave the placement groove 301 (which is also the state where the conductive sheet 103 is about to leave the card groove 302), that is, the surge protection module reaches a state of being 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 during energy storage. At the same time, after the housing 101 rises, it can drive the roller 601 to rotate clockwise to complete the final energy storage. Since the conductive sheet 103 is about to leave the slot 302, the conductive sheet 103 has also been 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, and the arc design drives the protrusion 704 to resume the fit with the rib 603, so as to realize 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 lift it lightly to complete the rapid disassembly of the surge protection module.

[0068] 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 bar 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 is failed in advance, which is more difficult to complete 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 the 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 for a 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 is overcome; on this basis, the failed surge protection module can be further moved to a state where it is about to be separated from the surge base 3 through the wedge rod 402, so that the staff can easily disassemble the failed surge protection module, and there is no need to consider the energy storage reaction force of the coil spring in this process, and the coil spring and the roller 601 are fully energized, so as to prepare for the rapid assembly of the new surge protection module; the overall process can also be normally applied when encountering a narrow space or an obstruction, and at the same time, combined with the movement of the slide bar 501 and the use of the roller 601, more requirements in actual use are met.

[0069] As a further improvement of this embodiment: in actual use, another control assembly 4 can be installed on the basis of the original control assembly 4, and the new control assembly 4 is located between the original control assembly 4 and the surge protection module, and the new control assembly 4 corresponds to the position of the slide bar 501 and the wedge-shaped groove 502 after the surge base 3 is moved to the left and protruded. At this time, the new button, long rod 401 and wedge-shaped rod 402 are located between the original button, long rod 401 and wedge-shaped rod 402, and the new wedge-shaped rod 402 corresponds to the wedge-shaped groove 502 after the slide bar 501 is moved to the left.

[0070] When the new button is pressed, the new wedge rod 402 can be driven down, and the new wedge rod 402 passes through the wedge groove 502 on the slide bar 501 that has not been moved right to reset, driving the slide bar 501 to move right to reset and release the pull rope 804. At this time, all surge protection modules are released from the limit and automatically rise a certain distance, and all of their slide bars 501 move right to the same position. Pressing the original button again drives the original wedge rod 402 down, and the original wedge rod 402 passes through the wedge groove 502 on the slide bar 501 after the right shift, driving the slide bar 501 to continue to move right and continue to release the pull rope 804, which can achieve the effect of further lifting the surge protection module described in the fourth embodiment, and all surge protection modules are lifted, which can be applicable to the comprehensive maintenance and replacement of all surge protection modules.
