Description

Technical Field

[0001] The utility model relates to the technical field of discharge performance testing, in particular to a testing tool for the discharge performance of a pulsed discharge circuit board. Background Art

[0002] A testing tool for the discharge performance of a pulsed discharge circuit board is usually used to evaluate the performance of the circuit board under pulsed discharge conditions.

[0003] Existing testing tools for the discharge performance of pulsed discharge circuit boards generally include key components such as a power supply, a control unit, a pulse generator, a load unit, and measurement and data recording devices. For example, in a Chinese patent with the publication number CN220271501U and the name "A testing tool for the discharge performance of a pulsed discharge circuit board", the connection pin is inserted into the connection socket at the pulsed discharge circuit board, the voltage test probe is clamped on the voltage test contact point of the testing tool body, the current test probe passes through the current test through-hole of the testing tool, and the test computer is connected to the pulsed discharge circuit board with a control cable; then the oscilloscope is turned on, the measurement parameters of each channel are adjusted, the test computer is turned on, and the pulsed discharge circuit board is controlled to discharge with the control software, and the lighting process and brightness of the neon bulb during the discharge process are observed. However, during its actual detection, since the overall tooling is an externally exposed structure, certain interference will be generated in this detection environment, which will then lead to errors in the test results. For example, devices such as high-power motors, generators, transformers, ovens, input and output ports of audio and video equipment, and high-pressure machines may cause magnetic field or electric field interference, which may damage the test equipment or the circuit board itself. At the same time, during its long-term use, the internal temperature of its detection work will gradually increase, and at this time, the stable change will cause peak spectrum drift, and excessive humidity may cause the serious consequence of abnormal high-voltage discharge and breakdown of the light tube. Therefore, this application provides a testing tool for the discharge performance of a pulsed discharge circuit board to meet the requirements. Summary of the Utility Model

[0004] The purpose of this application is to provide a testing tool for the discharge performance of a pulsed discharge circuit board, which solves the problem that environmental interference affects the detection structure in the prior art, and achieves the purpose of reducing interference factors during detection and improving the overall test accuracy and precision.

[0005] To achieve the above object, the present application provides the following technical solution: A test tool for the discharge performance of a pulse discharge circuit board, including an installation support member and a test tool body fixedly connected to the installation support member. The installation support member is in an L-shaped structure, and the top of the installation support member is rotatably connected to a sealing housing through a damping shaft body. The installation support member and the sealing housing can form a sealed cavity, and the test tool body is located inside the sealed cavity. An electrically insulating isolation layer is fixedly connected inside the sealing housing through a placement cavity, and an electrically insulating isolation plate body is fixedly connected to the side wall of the installation support member. The electrically insulating isolation layer and the electrically insulating isolation plate body can isolate the external magnetic field of the sealed cavity, and a filter is provided inside the sealed cavity.

[0006] Preferably, an installation port is provided at the bottom of the installation support member and is slidably connected with a fixing member through an electric slide rail inside the installation port. A silica gel sleeve is fixedly connected inside the fixing member, and the silica gel sleeve is used to seal the communication cavity.

[0007] Preferably, a temperature detector and a humidity detector are fixedly connected to the top of the installation support member, and a plurality of communication cavities are provided on the installation support member. A sealing plate member is rotatably connected inside the communication cavity.

[0008] Preferably, a driving motor is fixedly connected inside the communication cavity, and a driving rotating shaft is fixedly connected to the output end of the driving motor. The sealing plate member is fixedly inserted on the periphery of the driving rotating shaft.

[0009] Preferably, rubber members are fixedly connected to both the top and the bottom of the sealing plate member, and inclined cutting parts are provided on both sides of the rubber members.

[0010] Preferably, a clamping and fixing member is fixedly connected to the side wall of the installation support member, and a clamping and fixing groove is provided on the side wall of the sealing housing. The sealing housing can be clamped on the clamping and fixing member through the clamping and fixing groove.

[0011] Preferably, the rotation angle range between the installation support member and the sealing housing is from zero degree to one hundred and eighty degrees, and two protective members are fixedly connected to the top of the installation support member.

[0012] In summary, the technical effects and advantages of the present utility model:

[0013] 1. The structure of the utility model is reasonable. By setting a sealed cavity with an electrically insulating isolation layer and an electrically insulating isolation plate body, during its use, the test tooling body can be placed inside the sealed environment and cooperate with the electrically insulating isolation layer and the electrically insulating isolation plate body. When the test tooling body detects the circuit board, the electrically insulating isolation layer and the electrically insulating isolation plate body can effectively limit the current flow under the action of their own insulating materials, avoid the mutual interference of currents between different circuits, and then ensure the stability of the detection environment during the use of the test tooling body. At the same time, when detecting, the filter can also be turned on to make the filter enter the working state, further reducing the interference of high-frequency noise in the circuit, thereby improving the stability and accuracy of the detection.

[0014] 2. In the utility model, by setting a temperature detector and a humidity detector, during its detection and use, the temperature detector and the humidity detector can continuously and effectively detect and control the temperature and humidity inside the sealed cavity. When an abnormal situation occurs, the abnormal signal can be directly transmitted to the controller. The controller will effectively control the driving motor to drive the sealing plate member to rotate, thereby changing the sealing state of the sealing plate member, enabling the sealed cavity to perform air flow exchange independently, and achieving the effect of cooling.

[0015] 3. In the utility model, by setting an installation port and a fixing member, before its use, an external circuit can be directly used. The external circuit is clamped inside the fixing member, and the fixing member fixes the external circuit through a silicone sleeve. Then, the free end of the external circuit is fixed to the test tooling body, thereby grounding the test tooling body to reduce the interference of electromagnetic radiation. Grounding can release and disperse electromagnetic energy by connecting the circuit or equipment to the ground, ensuring the stability of the external environment during the detection of the test tooling body.

[0028] The following combines Figures 1-4 the embodiments shown to describe the technical solution of the present utility model:

[0029] It includes an installation support member 1 and a test tooling body 2 fixedly connected to the installation support member 1. The installation support member 1 is in an L-shaped structure, and the top of the installation support member 1 is rotatably connected to a sealing housing 3 through a damping shaft body. The installation support member 1 and the sealing housing 3 can form a sealed cavity, and the test tooling body 2 is located inside the sealed cavity. An electrically insulating isolation layer 4 is fixedly connected inside the sealing housing 3 through a placement cavity, and an electrically insulating isolation plate body 5 is fixedly connected to the side wall of the installation support member 1. The electrically insulating isolation layer 4 and the electrically insulating isolation plate body 5 can isolate the external magnetic field of the sealed cavity, and a filter 6 is arranged inside the sealed cavity.

[0030] During its use, the installation support 1 can be directly placed on a flat surface, so that the circuit board to be detected can be directly placed inside the test fixture body 2. Then, the sealing housing 3 can be pulled to rotate along the damping shaft under force. When it rotates to the top of the installation support 1, the installation support 1 and the sealing housing 3 will effectively form a sealed cavity, enabling the test fixture body 2 to be located inside a sealed environment. Thus, in cooperation with the electrical insulation layer 4 and the electrical insulation plate body 5, when the test fixture body 2 detects the circuit board, the electrical insulation layer 4 and the electrical insulation plate body 5 can, under the action of their own insulating materials, avoid the mutual interference of currents between different circuits, thereby ensuring the stability of the detection environment during the use of the test fixture body 2. At the same time, during the detection, the filter 6 can also be turned on to make the filter 6 enter the working state, further reducing the interference of high-frequency noise in the circuit, and thus improving the stability and accuracy of the detection.

[0031] An installation port that starts to communicate with the bottom of the installation support 1, and a fixing member 16 is slidably connected inside the installation port through an electric slide rail 15. A silica gel sleeve 17 is fixedly connected inside the fixing member 16, and the silica gel sleeve 17 is used to seal the communication cavity 11.

[0032] Before its use, an external circuit can be directly used. The external circuit is clamped inside the fixing member 16, so that the fixing member 16 fixes the external circuit through the silica gel sleeve 17. Then, the free end of the external circuit is fixed to the test fixture body 2 to complete the grounding operation of the test fixture body 2 to reduce the interference of electromagnetic radiation. Grounding can release and disperse electromagnetic energy by connecting the circuit or equipment to the ground, ensuring the stability of the external environment during the detection of the test fixture body 2.

[0033] A temperature detector 9 and a humidity detector 10 are fixedly connected to the top of the installation support 1, and a plurality of communication cavities 11 are provided on the installation support 1. A sealing plate member 13 is rotatably connected inside the communication cavity 11.

[0034] During its detection and use, the temperature detector 9 and the humidity detector 10 can continuously and effectively detect and control the temperature and humidity inside the sealed cavity. When an abnormal situation occurs, the abnormal signal can be directly transmitted to the controller, thereby reminding the operator to adjust the communication cavity 11, and then perform operations such as cooling and heat dissipation by rotating the sealing plate member 13.

[0035] A driving motor 12 is fixedly connected inside the communication cavity 11, and an output end of the driving motor 12 is fixedly connected to a driving rotating shaft. The sealing plate member 13 is fixedly inserted on the periphery of the driving rotating shaft.

[0036] During its use, when the temperature detector 9 or the humidity detector 10 transmits an abnormal signal to the inside of the controller, the controller will effectively control the drive motor 12, so that the drive motor 12 drives the sealing plate 13 to rotate, ending the change of the sealing state of the sealing plate 13, enabling the sealed cavity to perform air exchange autonomously, and ending to achieve the cooling effect.

[0037] Rubber parts 14 are fixedly connected to both the top and bottom of the sealing plate 13, and inclined cutting parts are provided on both sides of the rubber parts 14.

[0038] During its sealing use, the setting of the rubber parts 14 will effectively increase the contact friction force between the sealing plate 13 and the communication cavity 11, not only improving the fixed sealing effect of the sealing plate 13, but also to a certain extent, when the sealing plate 13 rotates, the rotational force can act on the rubber parts 14, causing the rubber parts 14 to deform under force, ending the change of their own dimensions, enabling the sealing plate 13 to rotate more autonomously, avoiding the situation of jamming during the rotation of the sealing plate 13, and improving the overall stability of use.

[0039] A clamping and fixing part 8 is fixedly connected to the side wall of the installation support part 1, and a clamping and fixing groove 7 is provided on the side wall of the sealing shell 3. The sealing shell 3 can be clamped on the clamping and fixing part 8 through the clamping and fixing groove 7.

[0040] During its use, the sealing shell 3 can be directly pulled so that it is stressed to form a clamping structure with the clamping and fixing part 8 through the clamping and fixing groove 7, and then its position is limited, to a certain extent avoiding the possibility of deviation, inclination or falling off under external force during detection.

[0041] The rotation angle range between the installation support part 1 and the sealing shell 3 is from zero degree to one hundred and eighty degrees, and two protective parts 18 are fixedly connected to the top of the installation support part 1.

[0042] Therefore, before and after its use, the sealing shell 3 directly rotates under the action of external force, ending the change of the state of the installation support part 1, so that during its use, a sealed cavity is formed for sealing detection, and when taking it away before and after use, the installation support part 1 can be made to be in an exposed state, simplifying the taking-away steps. At the same time, the setting of the protective parts 18 also effectively ensures the stability of the sealing shell 3 during rotation, avoiding the possibility of jamming during the rotation of the sealing shell 3.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
