The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0026] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0027] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description.

Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
[0030] This utility model discloses a withstand voltage testing device for electronic components, such as... Figure 1-5 As shown, it includes the main body 10 and the protective body 20.
[0031] The main structure 10 includes an electromagnetic shielding shell 11, a test chamber 12 disposed within the electromagnetic shielding shell 11, and a high-voltage generator 36 and a PLC controller 37 spaced apart below the test chamber 12. The high-voltage generator 36 and the PLC controller 37 are respectively disposed in two integrally formed mounting slots 35 inside the electromagnetic shielding shell 11. The test chamber 12 is provided with a liftable and movable support plate 15. The support plate 15 has symmetrically arranged and movable fixing plates 13 on both sides. The two fixing plates 13 are each equipped with a power terminal 14 connected to the high-voltage generator 36 on the side closest to each other. The high-voltage generator 36 is used to generate the high voltage required for the test and can be a power frequency transformer, a rectifier filter circuit, or a switching power supply module.
[0032] As a technical optimization of this utility model, in order to support the components during the test, rubber pads 16 and second screws 38 are respectively provided at the top and bottom of the support plate 15. The second screws 38 are used to drive the support plate 15 to move up and down.
[0033] As a technical optimization of this utility model, in order to facilitate the adjustment of the position of the power supply terminal 14 according to the component size, one end of each of the two fixing plates 13 is slidably connected to the slide rod 17, and the other end is respectively connected to the two reverse threads on the first screw 18. That is, by rotating the first screw 18, the two fixing plates 13 can be moved synchronously towards or away from each other.
[0034] As a technical optimization of this utility model, in order to facilitate the heat dissipation of the PLC controller 37 and the high voltage generator 36, heat dissipation holes 31 are provided on both the left and right sides of the electromagnetic shielding shell 11.
[0035] As a technical optimization of this utility model, in order to facilitate voltage display, a display screen 33 is provided on the front side of the electromagnetic shielding shell 11.

The knobs 32 are used to adjust the output voltage, and the indicator lights 34 are used to display the working status.
[0036] The protective mechanism 20 includes an electromagnetic shielding cover 21 that slides with the electromagnetic shielding shell 11. The electromagnetic shielding cover 21 has an observation window 22 that corresponds to the test chamber 12. Conductive foam 23 is also connected between the electromagnetic shielding cover 21 and the electromagnetic shielding shell 11. Specifically, the electromagnetic shielding cover 21 slides with the sliding groove 19 on the electromagnetic shielding shell 11 through a sliding part 24. The sliding part 24 is symmetrically arranged on one side of the electromagnetic shielding cover 21, and the other two sides of the electromagnetic shielding cover 21 are connected to the conductive foam 23.
[0037] As a technical optimization of this utility model, both the electromagnetic shielding shell 11 and the electromagnetic shielding cover 21 are made of carbon fiber material.
[0038] When the withstand voltage testing device for electronic components of this utility model is in operation, the electromagnetic shielding cover 21 is moved horizontally to remove it. The support plate 15 is rotated in conjunction with the second screw 38 to adjust the height of the support plate 15, thereby meeting the support requirements of different components. The component is placed on the support plate 15 in the test chamber 12, and the component contacts the rubber pad 16. The first screw 18 is rotated to move the two fixing plates 13, so that the fixing plates 13 drive the power terminal 14 to connect with the component. At the same time, the component is clamped and fixed by the fixing plates 13 and the power terminal 14. Then, the electromagnetic shielding cover 21 is installed above the test chamber 12 in conjunction with the sliding groove 19 to shield and protect the test chamber 12. The high voltage generator 36 is started by rotating the knob 32, and the high voltage power supply is adjusted to the predetermined value. The power supply is discharged for a period of time in this state. The component is observed through the observation window 22 to check whether the withstand voltage of the component meets the requirements.
[0039] In summary, the pressure withstand testing device for electronic components provided by this utility model has a simple structure and is easy to operate. It can prevent injury to observers when components malfunction, improve the safety of the test, and has great market value, making it worthy of widespread promotion and application.
