Technical Field
[0001] This utility model relates to the field of insulating products technology, and in particular to an insulating product insulation degree tester. Background Technology
[0002] Insulation testing of insulating products is a series of tests used to evaluate the ability of insulating materials or products to prevent current from passing through. Its core is to quantify the insulation performance of materials to ensure that they play a role in isolating conductive parts and preventing leakage or short circuits in electrical equipment.
[0003] In the patent application number 201320120980.X, the insulating rope testing clamp is connected to the main unit of the testing instrument. The clamp jaws are used to clamp the insulating rope and pull the insulating rope along its axis, thereby realizing insulation detection through the insulating rope testing electrode. However, the connection is exposed, which affects the service life. In addition, the detection shape is specific, which is not conducive to the detection of insulating products outside the specific shape. The debris generated during the detection is troublesome to clean, which affects the cleanliness of the instrument.
[0004] The existing patent (publication number: CN222319072U) is an insulation product insulation tester, which facilitates the testing of insulation products of different shapes and sizes by powering them on. By sliding the bottom plate up and down and opening and closing it, the debris that appears during the test can be put into the drawer for easy cleaning.
[0005] To address the aforementioned issues, existing patents have provided solutions. However, the clamps proposed in these patents are curved, and the contact tip is small in size, making it inconvenient to stably clamp plate-shaped insulating products and conduct insulation testing while energized, thus limiting their application.
[0006] Therefore, an insulation tester for insulating products is proposed. Utility Model Content
[0007] The purpose of this utility model is to provide an insulation product insulation tester that can solve the problem that the existing patent has a curved clamp and a small contact tip, which makes it inconvenient to stably clamp and conduct insulation tests on plate-shaped insulation products, thus limiting its use.
[0008] To achieve the above objectives, the present invention provides the following technical solution: an insulation product insulation tester, comprising a base plate, a fixing frame fixedly connected to the top of the base plate, a contact mechanism provided on the top of the base plate, an insulation tester body fixedly connected to the top of the base plate, and a baffle mechanism provided on the top of the base plate;
[0009] The contact mechanism includes a positive electrode flexible connecting wire, a positive electrode contact piece, a movable plate, and an adjusting rod. The front side of the positive electrode flexible connecting wire is electrically connected to the rear side of the positive electrode contact piece. The top of the positive electrode contact piece is fixedly connected to the bottom of the movable plate. The adjusting rod is disposed on the top of the movable plate and is threadedly connected inside the fixed frame.
[0010] Preferably, a bracket is fixedly connected to the top of the movable plate, and a rotating shaft is rotatably connected inside the bracket. The top of the rotating shaft is fixedly connected to the bottom of the adjusting rod.
[0011] Preferably, a rotating plate is fixedly connected to the right side of the adjusting rod, and a knob is rotatably connected inside the rotating plate.
[0012] Preferably, a fixing plate is fixedly connected to the top of the base plate, a negative electrode contact piece is fixedly connected to the top of the fixing plate, a negative electrode flexible connecting wire is electrically connected to the rear side of the negative electrode contact piece, both the positive electrode flexible connecting wire and the negative electrode flexible connecting wire are electrically connected to the interior of the insulation tester body, and the middle of both the positive electrode contact piece and the negative electrode contact piece are concave.
[0013] Preferably, card holders are fixedly connected to both sides of the rear side of the movable plate, and the surface of the card holders is in movable contact with the surface of the fixed frame.
[0014] Preferably, the partition mechanism includes two support plates, a partition plate, and a pull rod. The top of the support plate is fixedly connected to the bottom of the partition plate, and the pull rod is fixedly connected between the front sides of the two support plates. The partition plate is made of polytetrafluoroethylene and is located between the positive electrode contact piece and the negative electrode contact piece on opposite sides.
[0015] Preferably, slots are provided on both sides of the top of the base plate, and the support plate is movably inserted into the slots.
[0016] Preferably, silicone anti-slip pads are fixedly connected to the four corners of the bottom of the base plate.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This application, by setting up a contact mechanism, uses a large-area concave structure for both the positive and negative contact pieces. This allows for a tight fit between the concave curved surfaces and the columnar insulating product, preventing rolling and achieving stable clamping. It also allows for full contact with plate-shaped insulating products that are larger than the positive and negative contact pieces. With the help of the adjusting rod, rotating plate, and rotating shaft, the positive contact piece moves downward when the adjusting rod rotates, enabling the positive and negative contact pieces to contact and clamp the plate-shaped insulating product for insulation testing. This effectively solves the problem in existing patents where the clamping plate is arc-shaped and the contact tip is small, making it inconvenient to stably clamp plate-shaped insulating products and conduct insulation testing while energizing them, thus limiting its use.
[0019] 2. This application sets up a baffle mechanism. The PTFE baffle plate can be detachably connected to the support plate and the slot. In the non-testing state, it can be quickly deployed between the positive and negative contact plates. Its high insulation properties can be used to block the accidental current path, prevent the risk of short circuit, and ensure the safety of the insulation tester when it is idle.

[0027] 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.
[0028] Please see Figure 1-6 The present invention provides the following technical solution:
[0029] An insulation product insulation tester includes a base plate 1, a fixing frame 4 fixedly connected to the top of the base plate 1, a contact mechanism 5 provided on the top of the base plate 1, an insulation tester body 2 fixedly connected to the top of the base plate 1, and a baffle mechanism 6 provided on the top of the base plate 1.
[0030] The contact mechanism 5 includes a positive electrode flexible connecting wire 501, a positive electrode contact piece 502, a moving plate 503, and an adjusting rod 504. The front side of the positive electrode flexible connecting wire 501 is electrically connected to the rear side of the positive electrode contact piece 502. The top of the positive electrode contact piece 502 is fixedly connected to the bottom of the moving plate 503. The adjusting rod 504 is located on the top of the moving plate 503 and is threadedly connected to the inside of the fixing frame 4.
[0031] In this embodiment: Because the positive electrode contact 502 and the negative electrode contact 8 have large areas and are concave in the middle, when testing columnar insulating products, they are placed between the two. The concave structure fits the columnar body, preventing rolling and forming a stable clamp. After the insulation tester body 2 is powered on, it tests the insulation performance based on the current. When testing plate-shaped insulating products, they are first cut to be larger than the size of the positive and negative electrode contact 8 and placed on the negative electrode contact 8. Rotating the knob 15 moves the adjusting rod 504 down, causing the positive electrode contact 502 to move down until the positive electrode contact 502 and the negative electrode contact 8 are in close contact with the plate-shaped product, forming a circuit path. When testing is complete and no further testing is required, insert the support plate 601 into the slot 9. The PTFE baffle 602 is located between the positive electrode contact piece 502 and the negative electrode contact piece 8 to prevent accidental contact between the positive electrode contact piece 502 and the negative electrode contact piece 8, which could cause safety issues. By increasing the area of the positive electrode contact piece 502 and the negative electrode contact piece 8 and the concave structure in the middle, convenient testing of columnar and plate-shaped insulating products can be achieved. This solves the problem that the existing patent has a curved clamping plate and a small contact tip, which is inconvenient for stable clamping and insulation testing of plate-shaped insulating products, and has limited use.
[0032] Specifically, such as Figure 1 and Figure 3As shown, a bracket 11 is fixedly connected to the top of the movable plate 503, and a rotating shaft 10 is rotatably connected inside the bracket 11. The top of the rotating shaft 10 is fixedly connected to the bottom of the adjusting rod 504.
[0033] Specifically, such as Figure 3 and Figure 6 As shown, a rotating plate 13 is fixedly connected to the right side of the adjusting rod 504, and a knob 15 is rotatably connected inside the rotating plate 13.
[0034] Specifically, such as Figure 2 As shown, a fixing plate 7 is fixedly connected to the top of the base plate 1, and a negative electrode contact piece 8 is fixedly connected to the top of the fixing plate 7. A negative electrode flexible connecting wire 3 is electrically connected to the rear side of the negative electrode contact piece 8. Both the positive electrode flexible connecting wire 501 and the negative electrode flexible connecting wire 3 are electrically connected to the interior of the insulation tester body 2. The positive electrode contact piece 502 and the negative electrode contact piece 8 are both concave in the middle.
[0035] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, card holders 12 are fixedly connected to both sides of the rear side of the movable plate 503, and the surface of the card holder 12 is in contact with the surface of the fixed frame 4.
[0036] In this embodiment: the rotational connection design between the bracket 11 and the rotating shaft 10 ensures that when the adjusting rod 504 rotates, it only drives the moving plate 503 to make a vertical linear movement, effectively preventing the positive contact piece 502 from shifting during the adjustment process and ensuring the accuracy of contact with the insulating product. The rotational connection between the rotating plate 13 and the knob 15 allows for easy rotation of the rotating plate 13 and the adjusting rod 504 by holding the knob 15. The concave design of the positive and negative contact pieces 8 increases the contact area with the columnar insulating product and adapts to the contour of the columnar insulating product, facilitating the stable clamping of the columnar insulating product by the positive contact piece 502 and the negative contact piece 8. The movable contact between the clamp 12 and the fixing frame 4 provides guidance and limitation for the movement of the moving plate 503, further ensuring the stability and positioning accuracy of the positive contact piece 502 during movement.
[0037] Specifically, such as Figure 4 As shown, the partition mechanism 6 includes two support plates 601, a partition plate 602, and a pull rod 603. The top of the support plate 601 is fixedly connected to the bottom of the partition plate 602, and the pull rod 603 is fixedly connected between the front sides of the two support plates 601. The partition plate 602 is made of polytetrafluoroethylene and is located between the positive electrode contact piece 502 and the negative electrode contact piece 8 on opposite sides.
[0038] Specifically, such as Figure 2 and Figure 4 As shown, slots 9 are provided on both sides of the top of the base plate 1, and the support plate 601 is movably inserted into the slot 9.
[0039] Specifically, such as Figure 5 As shown, silicone anti-slip pads 14 are fixedly connected to the four corners of the bottom of the base plate 1.
[0040] In this embodiment: the PTFE baffle 602, with its excellent insulation properties, allows the support plate 601 to be inserted into the slot 9 when the insulation tester body 2 is idle, so that the baffle 602 is located between the positive electrode contact piece 502 and the negative electrode contact piece 8, which can effectively prevent the positive electrode contact piece 502 and the negative electrode contact piece 8 from accidentally contacting each other. The silicone anti-slip pads 14 at the four corners of the bottom of the base plate 1 increase the friction with the placement surface and prevent the insulation tester body 2 from sliding and shifting during operation.
[0041] Working Principle: When testing the insulation of columnar insulating products, the large area and concave center of the positive contact 502 and negative contact 8 allow the columnar insulating product to be placed directly between them. The concave design facilitates a close fit to the columnar insulating product, preventing rolling and creating a stable clamping effect. The insulation tester body 2 is then energized, allowing current to flow through the columnar insulating product. The tester body 2 detects its insulation performance based on the current flow. When testing plate-shaped insulating products, the plate-shaped product is first cut to a size larger than the positive contact 502 and negative contact 8 and placed on top of the negative contact 8. Then, the knob 15 is rotated, causing the rotating plate 13 to rotate. This causes the adjusting rod 504 to rotate and move downward within the fixed frame 4. The adjusting rod 504, through the rotating shaft 10, moves the moving plate 503 and the positive contact 502 fixed thereon downward until the positive contact 502 and negative contact 8 are in close contact with the plate-shaped insulating product, forming a circuit. At this point, the insulation tester body 2 begins operation, completing the process. For insulation testing of plate-shaped insulating products, when no testing is required, the support plate 601 is inserted into the slots 9 on both sides of the top of the base plate 1, so that the baffle plate 602 is located between the positive contact piece 502 and the negative contact piece 8. The baffle plate 602, made of polytetrafluoroethylene, has excellent insulation performance and effectively prevents accidental contact between the positive contact piece 502 and the negative contact piece 8, preventing short circuits or other safety problems caused by accidental contact, and ensuring the safety of the insulation tester body 2 when idle. By increasing the area of the positive contact piece 502 and the negative contact piece 8 and designing the middle of the positive contact piece 502 and the negative contact piece 8 to be concave, it is convenient to perform insulation testing on columnar or plate-shaped insulating products. This solves the problem that the clamping plate proposed in the existing patent is arc-shaped and the contact tip is small in volume, which is inconvenient for stable clamping and energizing of plate-shaped insulating products for insulation testing, and has limited use. It should be noted that the insulation tester body 2 is a mature technology that has been published, and its basic mechanism will not be elaborated here.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
