Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chemical foils test sample clamping, particularly to a chemical foils test sample clamping device. BACKGROUND

[0002] Chemical foils are key raw materials for aluminum electrolytic capacitors, and chemical foils testing mainly detects the performance and quality of the chemical foils. Chemical foils voltage resistance testing applies gradually increasing voltage to the chemical foils until breakdown or other abnormal phenomena occur, at which time the voltage is the voltage resistance value. Voltage resistance testing can evaluate the insulation performance and reliability of the chemical foils under high voltage.

[0003] Publication No. CN209356312U discloses a device for simultaneously detecting the voltage resistance of chemical foils in multiple channels, which comprises a temperature control system, a clamp set, a TV tester, chemical foils, and a test tank. The temperature control system comprises an electronic thermometer, a heating furnace, and a temperature control box. The electronic thermometer is connected to the data input end of the temperature control box, and the data output end of the temperature control box is connected to the heating furnace. The clamp set comprises several telescopic clamps, the top end of each telescopic clamp is connected to a control handle, the control handle is connected to the TV tester, and the bottom end of each telescopic clamp clamps the chemical foils. The test tank is filled with test liquid, and the electronic thermometer is suspended in the test liquid without contacting the tank body.

[0004] In the existing patent, the device for detecting the voltage resistance of chemical foils clamps the chemical foils into the test liquid for testing through telescopic clamps. However, the single clamp of such clamps has fewer clamping points for the chemical foils, which limits the firmness and stability of the chemical foils during clamping and testing. If the clamped chemical foils are subjected to external force due to misoperation, they may easily fall off, thereby affecting the testing operation of the chemical foils. Therefore, we propose a chemical foils test sample clamping device. UTILITY MODEL CONTENTS
