Description

Technical Field

[0002] An AC withstand voltage tester is an electrical testing instrument used to test the insulation performance of electrical equipment and insulating materials under AC high voltage. It is widely used in industries such as power, electronics, and electrical manufacturing. Its working principle is based on the breakdown characteristics of insulating media. During the test, the test sample is connected to the test circuit, and a gradually increasing AC voltage is applied to the test sample through a high voltage generator and maintained for a certain period of time. During this process, the instrument monitors the leakage current of the test sample and whether breakdown has occurred. If the leakage current is within the specified range and the tested insulation product has not broken down, then the tested insulation product has broken down and there is a defect in the insulation of the test sample.

[0003] When using the CS2670A model AC withstand voltage tester, the terminal block is connected to the wiring port of the AC withstand voltage tester main unit. Since the end of the connecting cable is plugged into the AC withstand voltage tester, if the connecting cable is pulled or touched, it may affect the stability of the connection between the terminal block and the AC withstand voltage tester main unit, thereby affecting the circuit loop. The AC withstand voltage tester main unit does not have a design to prevent the connecting cable from being touched, which needs to be improved. Existing AC withstand voltage testers have the problem that the main unit of the AC withstand voltage tester does not have a design to prevent contact with the cable. To address this issue, this application proposes an AC withstand voltage tester. Utility Model Content

[0016] 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.

[0017] Please see Figures 1 to 5 This utility model provides a technical solution: an AC withstand voltage tester, including an AC withstand voltage tester main unit 1; and an anti-touch component 2, including a fixed plate 21 fixed to the AC withstand voltage tester main unit 1 by screws, a pull-out plate 22 pulled and connected to the fixed plate 21, an anti-touch plate 23 fixed to the end of the pull-out plate 22 by screws, a base plate 3 perpendicular to the anti-touch plate 23, and a flip plate 4 flipped and connected to the base plate 3. The anti-touch plate 23 and the flip plate 4 are opposite to the operation panel embedded on the surface of the AC withstand voltage tester main unit 1. The anti-touch plate 23 and the flip plate 4 block the terminals of the data cable connected to the AC withstand voltage tester main unit 1, thereby preventing contact or... The effect of pulling the data cable terminal is that the flip plate 4 can be flipped, which does not affect the data cable end passing through the anti-touch plate 23 and connecting to the AC withstand voltage tester host 1; the wire clamping assembly includes a lifting rod 5 that slides through the anti-touch plate 23, a wire clamping plate 6 installed inside the anti-touch plate 23 and fixed to the bottom of the lifting rod 5 by screws, and a rotating cap 7 that is rotatably connected to the top of the lifting rod 5. By manually lifting the rotating cap 7 and the top of the lifting rod 5, the height position of the wire clamping plate 6 can be changed, which is conducive to the data cable end passing through. In addition, the downward movement of the wire clamping plate 6 can press down the data cable, which plays a role in clamping the wire and preventing accidental contact or pulling of the data cable terminal.

[0018] In this embodiment, the center of the anti-touch plate 23 is provided with a movable groove a for the vertical movement of the wire pressing plate 6. The wire pressing plate 6 is located on the bottom surface of the movable groove a and a protective sponge pad 61 is fixed thereon with adhesive. When the wire pressing plate 6 presses the wire, the protective sponge pad 61 contacts the data line, which serves to protect the data line and prevent damage to the outer insulation layer of the data line. The surface of the anti-touch plate 23 located in the movable groove a and facing the protective sponge pad 61 is the contact surface b. The data line contacts the contact surface b and the protective sponge pad 61.

[0019] In this embodiment, a fixed cylinder 8 is fixedly connected to the center of the top surface of the anti-collision plate 23. The rotating cap 7 is connected to the fixed cylinder 8 by a threaded connection. When the rotating cap 7 moves down, the rotating cap 7 is connected to the fixed cylinder 8, thereby limiting the position of the rotating cap 7. The rotating cap 7 is rotatably connected to the lifting rod 5. When the lifting rod 5 is fixed, the rotation of the rotating cap 7 is not affected.

[0020] In this embodiment, a reset assembly is connected to the corner of the flip plate 4 and the corner of the base plate 3. The reset assembly includes a connecting block 31 fixedly connected to the base plate 3, a rotating shaft 32 passing through the flip plate 4, and a reset torsion spring 33 sleeved on the outer side of the end of the rotating shaft 32. The rotating shaft 32 is installed between the opposing connecting blocks 31. The two ends of the reset torsion spring 33 are respectively embedded in the interior of the flip plate 4 and the connecting block 31. The flip plate 4 is rotatably connected to the rotating shaft 32 on the base plate 3. In manual operation, the flip plate 4 can be flipped for easy operation. When the flip plate 4 is released, it can be reset under the elastic deformation of the reset torsion spring 33, so that the flip plate 4 is perpendicular to the base plate 3.

[0021] In this embodiment, a winding rod 10 is screwed onto the surface of the base plate 3, and a "T"-shaped cylindrical winding drum 9 is screwed onto the surface of the base plate 3. The winding rod 10 and the winding drum 9 serve to wind the wire. When not being tested, the data cable can be wound around the outside of the winding rod 10 and the winding drum 9 for winding, thus having the function of storing the data cable.

[0022] Working principle and usage process of this utility model: When using an AC withstand voltage tester, the end of the data cable needs to be connected to the AC withstand voltage tester host 1; Manually pull the anti-touch plate 23 away from the AC withstand voltage tester host 1. The pull plate 22 is pulled out and connected to the fixed plate 21, so that there is a certain distance between the anti-touch plate 23 and the AC withstand voltage tester host 1. In manual mode, flip the flip plate 4, pass one end of the data cable through the anti-touch plate 23 and connect it to the data interface on the AC withstand voltage tester host 1; Manually move the rotating cap 7 and the lifting rod 5 vertically downward to change the height of the wire pressing plate 6. The wire pressing plate 6 moves down to press the wire, protecting the sponge pad 61 and making flexible contact with the data cable to avoid accidental contact or pulling of the data cable terminal. Release the flip plate 4, and under the elastic deformation of the return torsion spring 33, the flip plate 4 returns to its original position, making the flip plate 4 perpendicular to the bottom plate 3; The anti-touch plate 23 and the flip plate 4 cover the terminals of the data cable connected to the AC withstand voltage tester host 1, thereby preventing the data cable terminals from being touched or pulled. When not being tested, the data cable can be wound around the outside of the winding rod 10 and the winding drum 9 for winding, which has the function of storing the data cable; In summary: The AC withstand voltage tester of this application has a design to prevent contact with the connecting wire. The anti-contact plate 23 and the flip plate 4 serve to shield the connecting wire, preventing contact with or pulling of the data cable terminals. The pressure plate 6 moves down to press the wire, protecting the sponge pad 61 and making flexible contact with the data cable, thus providing a secure data cable function.
