GB4943.1 Figure 26 Roller Test Device

Also known as the core shaft testing device. It is designed in accordance with section 4.2.6 of GB4943.1 "Audio, Video, Information Technology, and Communication Technology Equipment Part 1: Safety Requirements" and related appendices, and is used to test the dielectric strength and mechanical strength of thin insulation materials in information technology equipment under specific pressure and mechanical bending.Here is a detailed introduction:GB4943.1 Figure 26 Roller Test DeviceOverall structure: Aluminum alloy and steel composite structures or aluminum profile frame structures are commonly used for strong stability. The scroll is made of 304 stainless steel material, and the triangular body has undergone electroplating and pointed quenching treatment, which is wear-resistant and not easily deformed. Core component specifications: The common reel diameters are 4.0mm, 6.0mm, 8.0mm, and 10.0mm, with a tolerance control of ± 0.2mm. It is suitable for testing thin layer materials of different thicknesses and can detect insulation components such as enameled round wires with a nominal diameter of more than 0.05-2.50mm. Weight configuration: Typically equipped with a main weight of 50N, it can be paired and combined to form loads of 100N and 150N. Additionally, two small weights of 1N can be used to adjust the tension applied to the sample as needed. Angle and operating parameters: There are mechanical limits at 10 ° and 230 ° positions, and the test angle can reach ± 230 ° to ensure accurate bending angle. The operation mode is mostly manual or hand cranked, and the default test frequency is usually set to 3 times. Clamping method: Adopting butterfly screw compression clamping, it can firmly fix the sample and avoid additional damage to the thin insulation material during clamping.
