Description

Technical Field

[0001] This utility model relates to the field of surge protector testing technology, and specifically to a device for open-circuit testing of surge protectors. Background Technology

[0002] A surge protector is an electronic protection device used in the field of surge protector testing technology. Its core function is to quickly conduct current and discharge surge energy to the ground when a transient overvoltage occurs in a circuit or communication line due to lightning strikes, switching operations, equipment failures, etc., thus preventing overvoltage damage to sensitive electronic equipment at the downstream end. It is a key component to ensure the safe and stable operation of electrical systems and electronic equipment.

[0003] During long-term use, surge protectors may experience damage or failure of their internal protective components due to repeated surge impacts, component aging, changes in environmental humidity, and other factors. Therefore, it is necessary to perform open-circuit testing on the surge protector to confirm whether it is damaged. However, open-circuit testing is often performed by manually wiring the surge protector, which results in extremely low testing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a device for open-circuit testing of surge protectors, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An apparatus for open-circuit testing of surge protectors includes: a base plate, with support seats fixedly installed at the four corners of the lower surface of the base plate, a control device fixedly installed at one end of the upper surface of the base plate, guide rails symmetrically fixedly installed on the upper surface of the base plate, a limiting mechanism slidably connected to the two guide rails, a surge protector being inserted into the top of the limiting mechanism, and the limiting mechanism being used to limit the position of the surge protector; and a plug-in mechanism, which is located at the end of the guide rail away from the limiting mechanism, is installed inside the base plate, and the output end of the plug-in mechanism extends to the outside of the base plate, and the plug-in mechanism is slidably connected to the base plate.

[0007] Using the above technical solution, when an open-circuit test of a surge protector is required, the operator places the surge protector to be tested on the limiting mechanism. Then, the limiting mechanism is moved along the guide rail. As the limiting mechanism moves the surge protector, it restricts the position of the surge protector, thereby increasing the stability of the surge protector during the open-circuit test and making it easier for the operator to operate. Furthermore, the plug-in mechanism allows for quick electrical connection of the surge protector, thus improving the testing process.

[0008] A further improvement of the present invention is that the limiting mechanism includes a sliding seat slidably connected to the guide rail. The sliding seat has a mounting groove in the center. Sliding rods are fixedly installed at equal intervals in the mounting groove inside the sliding seat. Clamping plates are slidably connected to several sliding rods. Auxiliary springs are sleeved on both ends of the sliding rods, and one end of the auxiliary spring is pressed against the side wall of the clamping plate. A pressing seat is fixedly installed in the center of the upper surface of the base plate, and the pressing seat is located between the two guide rails. A mating groove for pressing against the pressing seat is opened at the bottom end of the clamping plate.

[0009] Using the above technical solution, the operator places the surge protector to be tested on top of the sliding seat. At this time, the sliding seat is in its initial position away from the compression seat on the guide rail. Several sliding rods are evenly distributed in the mounting groove in the center of the sliding seat. The clamping plate is slidably connected through the sliding rods. The auxiliary springs at both ends of the sliding rods are in a naturally extended state, and the clamping plate is not subjected to lateral pressure, remaining in its initial position to facilitate quick placement of the surge protector. The operator pushes the sliding seat along the guide rail towards the insertion mechanism. When the sliding seat moves to the vicinity of the compression seat, the mating groove at the bottom of the clamping plate begins to engage with the inclined surface of the compression seat. As the sliding seat continues to move, the contact area between the mating groove and the inclined surface gradually increases. The lateral squeezing force generated by the inclined surface pushes the clamping plate to slide inward along the slide rod. During this process, the auxiliary springs at both ends of the slide rod are compressed by the clamping plate and contract, converting mechanical energy into elastic potential energy, which provides power for the subsequent clamping action. When the sliding seat moves to the preset test position and aligns with the insertion mechanism, the clamping plate completes the clamping and fixing of the surge protector under the combined action of the inclined surface squeezing force and the auxiliary spring. When the sliding seat is pushed in the opposite direction, the squeezing force disappears, and the auxiliary spring extends to push the clamping plate to reset.

[0010] A further improvement of this utility model is that: the end of the extrusion seat near the limiting mechanism is symmetrically provided with inclined surfaces that are inserted into the mating groove at the bottom of the clamping plate.

[0011] By adopting the above technical solution, the inclined surface provided at the end of the extrusion seat can increase the fitting degree between the extrusion seat and the clamping plate, thereby enabling the limiting mechanism to limit the surge protector during the movement process, and further improving the stability of the device during operation.

[0012] A further improvement of this utility model is that the clamping plate is L-shaped, and the top of the clamping plate is inserted into the bottom of the surge protector.

[0013] Using the above technical solution, the clamp is designed in an L-shape, with its top end tightly inserted into the bottom of the surge protector. Lateral compression ensures that the clamp fits against the side wall of the surge protector, limiting the horizontal displacement of the surge protector.

[0014] A further improvement of the present invention is that the insertion mechanism includes a gear rotatably connected inside the base plate, racks meshing with both sides of the gear, a connecting rod fixedly installed at one end of the gear, a rotating seat fixedly installed at the end of the connecting rod away from the gear to the outside of the base plate, two racks fixedly connected at the ends away from the gear to two mounting plates respectively, a fixing seat fixedly installed on one side of the mounting plate, an insertion seat fixedly installed at the top of the fixing seat, and one end of the insertion seat extending into the interior of the mounting plate, and the insertion seats inside the two mounting plates are electrically connected.

[0015] Using the above technical solution, the operator rotates the rotating seat outside the base plate, causing the connecting rod fixed to it to rotate, which in turn causes the gear inside the base plate connected to the connecting rod to rotate synchronously. Since the gears are meshed with diagonally arranged racks on both sides, the rotation of the gears is converted into synchronous reverse linear motion of the two racks. The racks drive the mounting plates connected to them to slide along the base plate through the end protrusions. The top of the fixed seat on one side of the mounting plate is equipped with a plug-in seat. As the mounting plate moves, the two plug-in seats will move closer or further away synchronously. When they move closer, they can accurately dock with the surge protector fixed on the limiting mechanism. Since the plug-in seats inside the two mounting plates have been electrically connected in advance, a test circuit can be quickly formed after docking to meet the open circuit test requirements. After the test is completed, the rotating seat is rotated in the opposite direction, and the gears and racks drive in the opposite direction, causing the plug-in seats to separate from the surge protector, completing one plug-in action cycle.

[0016] A further improvement of this utility model is that the two racks are arranged diagonally, and the ends of the racks are provided with protrusions that are fixedly connected to the mounting plate.

[0017] By adopting the above technical solution, the protrusion provided at the end of the rack can increase the connection and fit between the rack and the mounting plate, and further increase the stability of the device during operation.

[0018] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0019] 1. This utility model improves test stability and reduces human error through the setting of a limiting mechanism. It achieves standardized clamping force through the combination of mechanical extrusion and elastic clamping, and combines the L-shaped clamping plate to limit the horizontal displacement and vertical sway of the surge protector, avoiding product displacement caused by uneven force in traditional manual fixing, and ensuring the stability of the test circuit and the accuracy of the results. In addition, the setting of the limiting mechanism can simplify the operation process and improve the testing efficiency. There is no need for additional manual clamping steps. The operator can trigger clamping by pushing the sliding seat, and the clamping plate can be reset by pushing it in the opposite direction after the test. This greatly shortens the preparation and waiting time for testing a single device and is suitable for the needs of large-scale continuous testing.

[0020] 2. This utility model, through the setting of the plug-in mechanism, can drive the two mounting plates to move synchronously in opposite directions by meshing gears and diagonally arranged racks. This allows the top plug-in to quickly connect with the surge protector, avoiding poor contact caused by alignment deviations in traditional manual plugging and ensuring stable conduction of the test circuit. In addition, the plug-in mechanism can simplify the operation process and improve testing efficiency. There is no need for operators to manually adjust the position of the two plug-in, and plugging and unplugging can be completed with a single rotation action. This reduces the number of operation steps, adapts to the continuous testing needs of a large number of surge protectors, and shortens the test preparation time of a single device.

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the embodiments.

[0029] Example 1

[0030] like Figures 1-5As shown, this utility model provides a device for open-circuit testing of surge protectors, comprising: a base plate 1, with support seats 2 fixedly installed at the four corners of the lower surface of the base plate 1, a control device 3 fixedly installed at one end of the upper surface of the base plate 1, guide rails 6 symmetrically fixedly installed on the upper surface of the base plate 1, a limiting mechanism 4 slidably connected on the two guide rails 6, a surge protector 5 inserted into the top of the limiting mechanism 4, and the limiting mechanism 4 being used to limit the position of the surge protector 5; and a plug-in mechanism 7, which is located at the end of the guide rails 6 away from the limiting mechanism 4, is installed inside the base plate 1, and the output end of the plug-in mechanism 7 extends to the outside of the base plate 1, and the plug-in mechanism 7 is slidably connected to the base plate 1.

[0031] In this embodiment, when an open-circuit test is required on the surge protector 5, the operator places the surge protector 5 to be tested on the limiting mechanism 4. Then, the limiting mechanism 4 is moved along the guide rail 6. As the limiting mechanism 4 moves the surge protector 5, it restricts the position of the surge protector 5, thereby increasing the stability of the surge protector 5 during the open-circuit test and making it more convenient for the operator to operate. In addition, the plug-in mechanism 7 can quickly make electrical connections to the surge protector 5, thus improving the testing work.

[0032] Example 2

[0033] like Figure 3 and Figure 4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the limiting mechanism 4 includes a sliding seat 8 slidably connected to the guide rail 6, a mounting groove is provided in the center of the sliding seat 8, and sliding rods 9 are fixedly installed at equal intervals in the mounting groove inside the sliding seat 8. Clamping plates 10 are slidably connected to several sliding rods 9, and auxiliary springs 11 are sleeved on both ends of the sliding rods 9. One end of the auxiliary spring 11 is pressed and engaged with the side wall of the clamping plate 10. A pressing seat 12 is fixedly installed in the center of the upper surface of the base plate 1, and the pressing seat 12 is disposed between the two guide rails 6. A mating groove 13 is provided at the bottom end of the clamping plate 10 to press and engage with the pressing seat 12.

[0034] In this embodiment, the operator places the surge protector 5 to be tested on the top of the sliding seat 8. At this time, the sliding seat 8 is in the initial position away from the compression seat 12 on the guide rail 6. Several sliding rods 9 are evenly distributed in the mounting groove in the center of the sliding seat 8. The clamping plate 10 is slidably connected through the sliding rods 9. The auxiliary springs 11 at both ends of the sliding rods 9 are in a naturally extended state. The clamping plate 10 is not subjected to lateral compression force and remains in the initial position, which facilitates the quick placement of the surge protector 5. The operator pushes the sliding seat 8 to move along the guide rail 6 towards the insertion mechanism 7. When the sliding seat 8 moves to the vicinity of the compression seat 12, the mating groove 13 at the bottom of the clamping plate 10 begins to engage with the inclined surface of the compression seat 12. As the sliding seat 8 continues to move, the contact area between the mating groove 13 and the inclined surface gradually increases. The lateral squeezing force generated by the inclined surface pushes the clamping plate 10 to slide inward along the slide rod 9. During this process, the auxiliary springs 11 at both ends of the slide rod 9 are compressed by the clamping plate 10 and contract, converting mechanical energy into elastic potential energy, providing power for the subsequent clamping action. When the sliding seat 8 moves to the preset test position (i.e., when the surge protector 5 is aligned with the plugging mechanism 7), the clamping plate 10 completes the clamping and fixing of the surge protector 5 under the combined action of the inclined surface squeezing force and the auxiliary spring 11. When the sliding seat 8 is pushed in the opposite direction, the squeezing force disappears, and the auxiliary spring 11 extends to push the clamping plate 10 to reset.

[0035] like Figure 3 As shown, preferably, the end of the compression seat 12 near the limiting mechanism 4 is symmetrically provided with an inclined surface that is inserted into and engaged with the bottom groove 13 of the clamping plate 10.

[0036] In this embodiment, the inclined surface provided at the end of the compression seat 12 can increase the fitting degree between the compression seat 12 and the clamping plate 10, thereby enabling the limiting mechanism 4 to limit the surge protector 5 during the movement process, and further improving the stability of the device during operation.

[0037] like Figure 4 As shown, preferably, the clamping plate 10 is L-shaped, and the top of the clamping plate 10 is inserted into the bottom of the surge protector 5.

[0038] In this embodiment, the clamping plate 10 is designed in an L-shape, with its top end tightly inserted into the bottom of the surge protector 5. The lateral compression force ensures that the clamping plate 10 fits against the side wall of the surge protector 5, limiting the displacement of the surge protector 5 in the horizontal direction.

[0039] Example 3

[0040] like Figure 5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the plug-in mechanism 7 includes a gear 14 rotatably connected inside the base plate 1, with racks 15 meshing on both sides of the gear 14, a connecting rod 16 fixedly installed at one end of the gear 14, and a rotating seat 17 fixedly installed at the end of the connecting rod 16 away from the gear 14 extending to the outside of the base plate 1. The ends of the two racks 15 away from the gear 14 are respectively fixedly connected to two mounting plates 18. A fixing seat 19 is fixedly installed on one side of the mounting plate 18, and a plug-in seat 20 is fixedly installed at the top of the fixing seat 19. One end of the plug-in seat 20 extends into the interior of the mounting plate 18, and the plug-in seats 20 inside the two mounting plates 18 are electrically connected to each other.

[0041] In this embodiment, the operator rotates the rotating seat 17 outside the base plate 1, which drives the connecting rod 16 fixedly connected to it to rotate, thereby causing the gear 14 connected to the connecting rod 16 inside the base plate 1 to rotate synchronously. Since the gear 14 is meshed with diagonally arranged racks 15 on both sides, the rotation of the gear 14 will be converted into synchronous reverse linear motion of the two racks 15. The racks 15 drive the mounting plates 18 connected to them to slide along the base plate 1 through the end protrusions. The top of the fixed seat 19 on one side of the mounting plate 18 is provided with a plug seat 20. As the mounting plate 18 moves, the two plug seats 20 will move closer or further away synchronously. When they move closer, they can accurately dock with the surge protector 5 fixed on the limiting mechanism 4. Since the plug seats 20 inside the two mounting plates 18 have been electrically connected in advance, a test circuit can be quickly formed after docking to meet the open circuit test requirements. After the test is completed, the rotating seat 17 is rotated in the opposite direction, and the gear 14 and rack 15 drive in the opposite direction, causing the plug seat 20 to separate from the surge protector 5, completing one plugging action cycle.

[0042] It should be noted that the control device 3 and the plug-in mechanism 7 are electrically connected.

[0043] like Figure 5 As shown, preferably, the two racks 15 are arranged diagonally, and each end of the rack 15 is provided with a protrusion that is fixedly connected to the mounting plate 18.

[0044] In this embodiment, the protrusion provided at the end of the rack 15 can increase the connection and fit between the rack 15 and the mounting plate 18, and further increase the stability of the device during operation.

[0045] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
