[0001] This utility model relates to the technical field of power supply electrical stress fault reproduction control equipment, specifically a power supply electrical stress fault reproduction control equipment. Background Technology

[0002] Power supply electrical stress fault reproduction control equipment is a specialized testing device used to simulate, reproduce, and analyze the fault behavior of power supply equipment under abnormal electrical stress conditions (such as overvoltage, undervoltage, surge, transient pulse, etc.). Its core purpose is to reproduce the extreme electrical environments that power supplies may encounter in practical applications in a controllable manner, thereby verifying product reliability, optimizing design, or diagnosing faults.

[0003] Due to the usage characteristics of power supply electrical stress fault reproduction control equipment, the following types of equipment are often equipped with such equipment: laboratories or test benches, production lines (quality inspection areas), etc. Power supply electrical stress fault reproduction control equipment installed on production lines will be affected by the vibration of the production line. This will not only cause the power supply electrical stress fault reproduction control equipment to shake, but also cause the power supply electrical stress fault reproduction control equipment to loosen due to shaking. Such shaking power supply electrical stress fault reproduction control equipment may cause surface collisions and damage to the machine body, while loose power supply electrical stress fault reproduction control equipment may fall off, thus directly affecting its normal use function. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a power supply electrical stress fault reproduction control device, comprising a control body, wherein fixing members for fixing are fixedly installed on the rear sides of both the left and right sides of the control body, and two connection holes for connection are opened on the rear of each of the two fixing members, and fasteners for fixing are provided on the inner walls of the several connection holes.

[0006] The control body is provided with protective plates on the top, bottom and rear sides, and the surface of the protective plates is provided with heat dissipation vents. The protective plates are composed of several heat-conducting plates and heat dissipation plates stacked alternately.

[0007] Furthermore, several of the heat-conducting plates are thermally conductive silicone pad structures, while several of the heat dissipation plates are aluminum plate structures, and the heat dissipation plates are located inside the protective plate.

[0008] Furthermore, all of the aforementioned heat dissipation vents are provided with elliptical openings, and the major axis of the elliptical openings is perpendicular to the length direction of the protective plate.

[0009] Furthermore, both of the aforementioned fasteners are L-shaped angle iron structures, and the plurality of the aforementioned connecting holes are rectangular openings.

[0010] Furthermore, the fastener includes a screw fitted on the inner wall of the connecting hole, and the surface of the screw is fitted with a snap-fit ​​ring for snapping.

[0011] Furthermore, each of the aforementioned snap-fit ​​rings includes a rubber ring and several rectangular protrusions fixedly installed on one side of the surface of the rubber ring, wherein the rubber ring is a ring structure with a notch on one side.

[0012] Furthermore, the surfaces of several of the protective plates are bonded to the surface of the control body using frame-type double-sided adhesive.

[0013] Compared with the prior art, this utility model provides a power supply electrical stress fault reproduction control device, which has the following beneficial effects:

[0014] 1. This device has the effect of reinforcing the connection position, preventing the device from falling due to loose connection during use, ensuring the normal use of the device, and the surface of the device is covered with a protective heat dissipation structure, which not only protects the surface of the device but also increases its heat dissipation effect, thereby preventing damage to the surface of the device.

[0021] 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 some embodiments 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.

[0022] Please see Figures 1 to 5 The power supply electrical stress fault reproduction control device in this embodiment includes a control body 1. Fixing members 2 are fixedly installed on the rear sides of both the left and right sides of the control body 1. Both fixing members 2 are L-shaped angle iron structures. Several connecting holes 201 are rectangular openings. Two connecting holes 201 for connection are opened on the rear of both fixing members 2. The inner walls of several connecting holes 201 are provided with fasteners 3 for fixing. The fasteners 3 include screws 301 sleeved on the inner walls of the connecting holes 201. The surface of the screws 301 is sleeved with snap rings 302 for snapping. Several snap rings 302 include rubber rings 303 and several rectangular protrusions 304 fixedly installed on one side of the surface of the rubber rings 303. The rubber rings 303 are annular structures with a notch on one side.

[0023] The control body 1 has protective plates 4 on its top, bottom, and rear sides. The surfaces of the protective plates 4 are bonded to the surface of the control body 1 with frame-type double-sided adhesive 6. The surfaces of the protective plates 4 are provided with heat dissipation vents 5. The heat dissipation vents 5 are elliptical openings, and the major axis of the elliptical openings is perpendicular to the length direction of the protective plate 4. The protective plate 4 is formed by overlapping several heat-conducting plates 401 and heat dissipation plates 402. The heat-conducting plates 401 are all thermally conductive silicone pads, and the heat dissipation plates 402 are all aluminum plates. The heat dissipation plates 402 are located inside the protective plate 4.

[0024] The working principle of the above embodiments is as follows:

[0025] When the equipment is in use, the fasteners 3 can ensure the fixation of the control body 1. The control body 1 in this equipment has the function of power supply electrical stress fault reproduction control equipment, and it is a mature technology. This equipment highlights the innovative structure of the equipment and will not elaborate on the mature technology.

[0026] During the fixing process, the rubber ring 303 in the fastener 3, in conjunction with the rectangular protrusion 304, ensures that after the bolt is tightened, the notch structure of the rubber ring 303 allows the screw 301 connection position to elastically contract and compensate for axial clearance, preventing loosening and ensuring the stability of the control body 1 during the connection process. Meanwhile, the rectangular protrusion 304 increases the friction at the connection position, ensuring the stability of the connection.

[0027] The heat dissipation plate 402 and heat conduction plate 401 inside the protective plate 4 of the equipment can better dissipate the heat from the surface of the control body 1. The elliptical contour of the heat dissipation port 5 has a more uniform transition than the round or square hole, reducing stress concentration at sharp corners and improving fatigue resistance. The elliptical port provides a larger effective ventilation area (compared to the rectangular port of equal width) and has less airflow disturbance, which can better increase the heat dissipation effect of the protective plate 4. This can avoid the problem of high temperature affecting the use of control components inside the control body 1 and ensure the normal use of the equipment.

[0028] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
