Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment, in particular to an electrical fast pulse group immunity testing device. Background Art

[0002] An electrical fast transient pulse group refers to a limited number of clearly identifiable pulse sequences or oscillations of limited duration. A single pulse in the pulse group has a specific repetition period, voltage amplitude, rise time and pulse width. When testing the immunity of electrical fast pulse groups, a test device is required. If dust enters the jacks on the panel of the test device, it is easy to cause unstable current transmission and affect the accuracy of the test results.

[0003] In the prior art, such as Chinese patent publication number CN209624701U, an electrical fast pulse group immunity test device is disclosed, including a tester body, handle frames are embedded and installed on both sides of the tester body, a dustproof component is installed on the top edge of the tester body, and a storage plate is fixedly installed on the middle part of the top of the tester body by heat fusion, and wire receiving grooves are opened at equal distances on the top of the storage plate. The utility model has a scientific and reasonable structure and is safe and convenient to use. By placing the plug at one end of the connecting wire into the convex groove, straightening the connecting wire along the wire receiving groove, and winding the connecting wire from the back end of the wire receiving groove to another wire receiving groove, the other plug can also be placed in the convex groove, and then the limit swing rod is swung to prevent the connecting wire from slipping out of the wire receiving groove. The problem that the connecting wires of the existing tester are directly stored in the drawer after use, and multiple wires are easily entangled in the drawer, making it inconvenient to take out, is solved.

[0004] Although the above patent uses Velcro to fix the dustproof cloth on the tester panel to prevent dust from entering the plug, some dust will adhere to the surface of the plug during use and before the dustproof cloth is covered. The accumulation of dust will still affect the current transmission stability of the plug, and the operator's regular use of cotton swabs for cleaning will undoubtedly increase the workload. Therefore, in response to the above problems, we propose a new type of electrical fast pulse group immunity test device. Utility Model Content

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figure 1-Figure 6 As shown, the utility model provides an electrical fast pulse group immunity test device, including a tester body 1, a shield 2 is arranged on the front side of the tester body 1, a dustproof plate 21 is symmetrically arranged on the front surface of the shield 2, a motor frame 22 is symmetrically fixedly connected to the inner surface wall of the front side of the shield 2, a driving motor 23 is installed on the rear surface of the motor frame 22, an output end of the driving motor 23 slides through the outer surface of the motor frame 22 and the shield 2 and extends to the front side, a fan blade 24 is fixedly connected to the output end of the driving motor 23, a connecting frame 4 is fixedly connected to the front surface of the shield 2 near the edge, the front surface of the connecting frame 4 is inclined, a cover plate 42 is fixedly connected to the front surface of the connecting frame 4, a plurality of triangular grooves 41 are opened through the inner bottom of the connecting frame 4, a U-shaped handle 11 is symmetrically fixedly connected to the front surface of the tester body 1 near the edges on both sides, the cross section of the triangular groove 41 is triangular, a pressure block 3 is fixedly connected to the inner surface wall of one side of the shield 2, a travel switch 15 is arranged on the front surface of the tester body 1 near one of the corners, and the pressure block 3 and the travel switch 15 are in corresponding positions.

[0026] The effect achieved by the entire embodiment 1 is that the tester body 1 is a device for testing the immunity to electrical fast pulse groups, and its working principle has been fully disclosed in the above-mentioned comparative documents, and will not be elaborated on here. When the tester body 1 is used, the shield 2 is rotated to the front side of the tester body 1 to cover the panel of the tester body 1 under the action of the first connecting block 12 and the second connecting block 32, and the pressure block 3 on the inside of the shield 2 will squeeze and trigger the travel switch 15. At this time, the travel switch 15 sends an electrical signal to the drive motor 23 to control its start. When the drive motor 23 is started, it will drive the fan blades 24 to rotate at high speed for one minute. During this process, the pressure difference generated by the rotation of the fan blades 24 will cause the air inside the shield 2 to be pumped out. When the plug is pulled out, the dust and impurities just attached to the plug will be drawn out from the holes on the surface of the dustproof plate 21 and sent into the interior of the connecting frame 4 and the cover plate 42, and then discharged from the triangular groove 41 below with the air, which has the effect of keeping the plug clean without the need for regular cleaning by personnel, reducing the workload of operators, ensuring the stability of current transmission, and being easy to use and highly practical. The U-shaped handle 11 is mainly used to facilitate the taking of the tester body 1. The holes on the surface of the dustproof plate 21 are conical, and the inner diameter on the side close to the tester body 1 is larger than the inner diameter on the other side, so that dust can easily pass through from the rear side of the dustproof plate 21 but is not easy to pass from the front to the rear side. The motor frame 22 is mainly used to install the drive motor 23.

[0027] Embodiment 2, as Figure 1-Figure 4 As shown, the top of the tester body 1 is symmetrically fixedly connected with a first connecting block 12 near the front surface, the outer surfaces of the two first connecting blocks 12 on the opposite sides are rotatably connected with second connecting blocks 32, the bottoms of the two second connecting blocks 32 are fixedly connected to the top of the protective cover 2, the outer surfaces on both sides of the second connecting blocks 32 are fixedly connected with second buckles 31, the front surface of the protective cover 2 is fixedly connected with a block 33 near the top, the top of the tester body 1 is fixedly connected with a first buckle 13, the rear surface of the first buckle 13 is fixedly connected with a pull rod 14, the first buckle 13 and the block 33 are snap-connected, and the second buckle 31 and the U-shaped handle 11 are snap-connected.

[0028] The effect achieved by the entire embodiment 2 is that when the protective cover 2 needs to be opened during use of the tester body 1, the two second buckles 31 are pushed outward to disengage them from the U-shaped handle 11 and then rotated upward, and then the block 33 on the surface of the protective cover 2 will be engaged with the first buckle 13, thereby fixing the protective cover 2 so that it does not affect the use of the tester body 1. After use, pull the pull rod 14 to disengage the first buckle 13 and the block 33, and then rotate the protective cover 2 downward. At this time, the second buckles 31 on both sides will be stuck on the U-shaped handle 11, thereby completing the fixation of the protective cover 2. The overall structure is reasonable, the operation is convenient, and the practicability is high.

[0029] Working principle: when the tester body 1 is used up, the shield 2 is rotated to the front side of the tester body 1 under the action of the first connecting block 12 and the second connecting block 32 to cover the panel of the tester body 1, and the pressure block 3 inside the shield 2 will squeeze and trigger the travel switch 15. At this time, the travel switch 15 sends an electrical signal to the drive motor 23 to control its start. When the drive motor 23 is started, it will drive the fan blades 24 to rotate at high speed for one minute. During this process, the pressure difference generated by the rotation of the fan blades 24 will cause the air inside the shield 2 to be drawn out. When drawn out, the dust and impurities just attached to the plug will be drawn out from the holes on the surface of the dustproof plate 21 and sent to the inside of the connecting frame 4 and the cover plate 42, and then discharged from the triangular groove 41 below with the air, which does not require people to touch the plug. Regular cleaning by the operator can also maintain the cleanliness of the plug, reduce the workload of the operator, ensure the stability of current transmission, be easy to use, and have high practicality. In addition, when the protective cover 2 needs to be opened during use of the tester body 1, the two second buckles 31 are pushed outward to disengage them from the U-shaped handle 11 and then rotated upward. Then, the block 33 on the surface of the protective cover 2 will be engaged with the first buckle 13, thereby fixing the protective cover 2 so that it does not affect the use of the tester body 1. After use, pull the pull rod 14 to disengage the first buckle 13 and the block 33, and then rotate the protective cover 2 downward. At this time, the second buckles 31 on both sides will be stuck on the U-shaped handle 11, thereby completing the fixation of the protective cover 2. The overall structure is reasonable, the operation is convenient, and the practicality is high.
