Description

Technical Field

[0001] This utility model relates to the field of voltage regulator testing technology, specifically to a semi-automatic voltage regulator testing device. Background Technology

[0002] A ZnO (zinc oxide) voltage regulator is an electronic component based on the characteristics of zinc oxide varistors, primarily used for voltage protection and regulation in circuits. Its core principle utilizes the non-linear resistance characteristics of zinc oxide material when voltage changes to achieve overvoltage protection, voltage clamping, and voltage regulation, protecting downstream equipment from transient high-voltage surges caused by lightning strikes, static electricity, and switching operations.

[0003] During the production and processing of ZnO voltage regulators, high-voltage testing is required to prevent the ZnO voltage regulator from failing to operate stably under rated high voltage (such as threshold voltage drift or decrease in nonlinear coefficient), which could lead to failure in actual overvoltage protection and damage to the protected equipment.

[0004] Currently, the testing of ZnO voltage regulators is often done manually by clamping the high-voltage point and grounding point of the ZnO voltage regulator. Only one ZnO voltage regulator can be tested at a time, which is time-consuming, labor-intensive, inconvenient, and inefficient. Utility Model Content

[0005] The purpose of this invention is to provide a semi-automatic detection device for voltage regulators to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a semi-automatic detection device for a voltage regulator, which includes a base, a top cover, a high-voltage contact head, a ground contact head, and a moving component. The base has multiple limiting grooves adapted to the voltage regulator. The top cover is detachably connected to the base. There are multiple high-voltage contact heads, which are arranged on the first side of the limiting grooves and correspond one-to-one with the limiting grooves. The multiple high-voltage contact heads are mounted on the top cover and respectively contact the corresponding voltage regulator. The ground contact head is arranged on the second side of the limiting groove. The moving component is used to move the ground contact head to contact the corresponding voltage regulator.

[0007] Furthermore, the upper cover plate is connected to the base by screws.

[0008] Furthermore, the upper cover plate is provided with multiple springs, each of which corresponds to a single high-voltage contact head. The springs cause the high-voltage contact head to tend to move toward the corresponding voltage regulator.

[0009] Furthermore, the moving component includes a lead screw, a moving block, and a motor. The two ends of the lead screw are rotatably connected to the base, and the moving block is provided with a ground contact head. The moving block is sleeved on the lead screw and threadedly connected to the lead screw. The motor is used to drive the lead screw to rotate.

[0010] Furthermore, the limiting groove is an elongated groove, and the ratio of its depth to the height of the voltage regulator is 1:2.

[0011] Furthermore, the motor is mounted on one side of the base, and a shielding film is provided on the surface of the motor.

[0012] Furthermore, it also includes a limiting block, which is installed on the base and used to limit the grounding contact head during detection.

[0013] Furthermore, a high-voltage pulse source interface is provided on the top of the base.

[0014] The beneficial effects of this invention are as follows: This invention can clamp multiple voltage regulators at once, enabling the testing of multiple voltage regulators, ensuring consistency in testing quality, and improving testing efficiency. The grounding contact head is moved to the designated position via a moving component to perform high-voltage testing on the voltage regulator to be tested, reducing the number of times products need to be clamped and changed, simplifying the operation process, and reducing labor intensity.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only one embodiment of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To make the objectives, technical solutions and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.

[0021] In the following description, references to "an embodiment," "an embodiment," "an example," "example," etc., indicate that the described embodiment or example may include a particular feature, structure, characteristic, property, element, or limitation, but not every embodiment or example necessarily includes that particular feature, structure, characteristic, property, element, or limitation. Furthermore, the repeated use of the phrase "an embodiment according to this application," while possibly referring to the same embodiment, does not necessarily refer to the same embodiment.

[0022] like Figures 1-2 As shown, this utility model discloses a semi-automatic detection device for a voltage regulator, which includes a base 1, an upper cover plate 2, a high-voltage contact head 3, a ground contact head 4, and a moving component 5. The base 1 has multiple limiting grooves adapted to the voltage regulator. The upper cover plate 2 is detachably connected to the base 1. Multiple high-voltage contact heads 3 are arranged on the first side of the limiting grooves and correspond one-to-one with each groove. The high-voltage contact heads 3 are mounted on the upper cover plate 2 and contact their respective voltage regulators. The ground contact head 4 is arranged on the second side of the limiting grooves. The moving component 5 is used to move the ground contact head 4 to contact the corresponding voltage regulator. The ground contact head 4 is connected to an external ground wire connection.

[0023] Initially, the upper cover plate 2 is not connected to the base 1, and the ground contact head 4 is positioned away from the limiting slot under the action of the moving component 5. Multiple ZnO voltage regulators (i.e., voltage stabilizers) to be tested are placed in their respective limiting slots on the base 1. Since the limiting slots are adapted to the voltage regulators, the accurate and stable position of the voltage regulators within the slots is ensured, providing a good foundation for subsequent testing. The upper cover plate 2 is then installed onto the base 1. At this point, the multiple high-voltage contact heads 3 installed on the upper cover plate 2 are located precisely on the first side of the limiting slot and correspond one-to-one with the voltage regulators placed in the limiting slots. The high-voltage contact heads 3 will make close contact with their corresponding voltage regulators, establishing a high-voltage connection channel. The moving component 5 (e.g., a cylinder) is activated, and the ground contact head 4 moves along the distribution direction of the limiting slots, ultimately making contact with the voltage regulators in the limiting slots, establishing a ground connection channel. This device facilitates voltage regulator clamping, provides secure clamping, reduces manpower, and increases efficiency.

[0024] After both the high-voltage contact 3 and the ground contact 4 are connected to the voltage regulator, the high-voltage source applies the rated high voltage to the high-voltage contact 3. Based on the nonlinear resistance characteristics of zinc oxide material under voltage changes, the ZnO voltage regulator exhibits specific electrical properties under high voltage, such as overvoltage protection, voltage clamping, and voltage regulation. The voltage and current parameters at both ends of the voltage regulator are detected and analyzed by the detection circuit to determine whether it can operate stably under the rated high voltage and whether there are problems such as threshold voltage drift or a decrease in the nonlinear coefficient. After the voltage regulator is tested, the control moving component 5 moves the ground contact 4 to the next voltage regulator to be tested, and the above testing process is repeated. Compared to manual one-by-one testing, this method is more efficient, reduces labor intensity, simplifies the operation, and improves testing efficiency, while meeting the test requirements.

[0025] This invention allows for the simultaneous clamping of multiple voltage regulators, enabling the testing of multiple regulators, ensuring consistent testing quality, and improving testing efficiency. The grounding contact 4 is moved to a designated position via the moving component 5 to perform high-voltage testing on the voltage regulator to be tested, reducing the number of times products need to be clamped and changed, simplifying the operation process, and reducing labor intensity.

[0026] In one embodiment, the upper cover plate 2 is connected to the base 1 by screws. In this embodiment, the upper cover plate 2 has screw holes, and the threaded end of the screw passes through the screw holes and is threaded to the base 1. The structure is simple, low-cost, and easy to disassemble and install.

[0027] In one embodiment, the upper cover plate 2 is provided with multiple springs 6, each corresponding to a single high-voltage contact 3. The springs 6 cause the high-voltage contact 3 to tend to move towards the corresponding voltage regulator. That is, in this embodiment, the springs 6 are sleeved on the high-voltage contact 3, with both ends of the springs 6 connected to the high-voltage contact 3 and the upper cover plate 2, respectively. After the upper cover plate 2 is installed on the base 1, the high-voltage contact 3 is pressed tightly against the voltage regulator under the action of the springs 6, thereby establishing a stable and reliable electrical connection and preparing for subsequent high-voltage testing.

[0028] In one embodiment, the moving component 5 includes a lead screw 51, a moving block 52, and a motor 53. The two ends of the lead screw 51 are rotatably connected to the base 1, and the moving block 52 is provided with a ground contact head 4. The moving block 52 is sleeved on the lead screw 51 and threadedly connected to the lead screw 51. The motor 53 is used to drive the lead screw 51 to rotate.

[0029] Motor 53 drives lead screw 51 to rotate. Since moving block 52 is sleeved on lead screw 51 and threadedly connected to lead screw 51, the rotation of lead screw 51 will drive moving block 52 to move along lead screw 51. Ground contact head 4 moves together with moving block 52, gradually approaching or moving away from the target voltage regulator. In this embodiment, motor 53 is connected to controller. The controller sends pulses, and the driver on motor 53 receives the pulses to realize the start and stop of motor 53. That is, the movement of ground contact point can be controlled by program. Motor 53 moves to a specified distance and automatically stops after each program segment is executed. The controller is existing technology and will not be described in detail here.

[0030] In one embodiment, the limiting groove is an elongated groove with a depth-to-height ratio of 1:2. This means that after the voltage regulator is placed in the limiting groove, it prevents the regulator from moving forward, backward, left, or right, while simultaneously fixing its vertical movement via a cover plate. In this embodiment, each contact segment uses a soft contact.

[0031] In one embodiment, the motor 53 is mounted on one side of the base 1, and a shielding film is provided on the surface of the motor 53. This prevents external electromagnetic interference caused by high voltage and effectively solves the problem of the motor 53 having a default signal output. In this embodiment, the housing of the motor 53 has built-in mounting holes, and it is fixed to the side of the base 1 with screws.

[0032] In this embodiment, a limiting block 7 is also included. The limiting block 7 is installed on the base and is used to limit the position of the grounding contact during testing. Specifically, the limiting block 7 is installed at the grounding electrode of the ZnO voltage regulator. During the zinc oxide testing and installation process, it assists in positioning the grounding contact, ensuring that the connection between the grounding contact and the voltage regulator's grounding electrode meets the testing requirements. This avoids testing errors caused by poor contact or positional deviation, improving the accuracy and reliability of the grounding electrode testing.

[0033] In this embodiment, the ZnO voltage regulator is U-shaped, and multiple limiting blocks 7 are provided on the second side of the limiting groove. They are all set on the base 1, with their first ends in contact with the corresponding voltage regulator and their second ends being free ends. When the motor 53 controls the ground contact head 4 to move and contact the second end of the limiting block 7, it prevents the voltage regulator from being deformed by force when the ground contact head 4 moves, and at the same time limits the position of the ground contact head.

[0034] In one embodiment, a high-voltage pulse source interface 8 is provided on the top of the base 1. The high-voltage pulse signal generated by the high-voltage pulse source interface 8 can more realistically simulate the complex electrical environment that the voltage regulator may encounter in actual operation, such as instantaneous high voltage and voltage fluctuations. After the upper cover plate 2 is installed on the base 1, the high-voltage pulse source interface 8 is electrically connected to multiple high-voltage contact heads 3 for easy detection.

[0035] The above description of the disclosed embodiments enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
