Description

Technical Field

[0001] The utility model relates to the technical field of fuse testing, in particular to a fuse tension testing device. Background Art

[0002] With the advancement of technology, more and more electrical appliances are entering people's homes. In addition to traditional refrigerators, color TVs and the like, modern houses are more likely to use whole-house intelligence. Once these intelligent devices and home appliances and other products have quality problems, the products may be damaged at the least, or major safety accidents such as explosions and fires may occur at the worst, seriously threatening people's lives and property safety. Therefore, the above-mentioned home appliances must be installed with fuses to prevent dry burning or quality accidents.

[0003] The push-pull force test of the fuse is to ensure the installation strength of the fuse and prevent the internal structure of the temperature fuse from being damaged due to a certain force during the use or installation process of the customer, including the displacement of components to produce re-conduction, reduce creepage distance, electrical clearance and other electrical requirements. This will affect the end customer's use of home appliances, which may cause dry burning and fire or non-conduction and affect the use of home appliances. The importance of the push-pull force test can be imagined, although the current manufacturer's test methods are constantly improving. The traditional method is to use a simple fixture for testing. During the test, the fixture is unstable and easy to shake, so that the test results cannot truly reflect the quality of the fuse. In addition, the traditional fixture uses a mechanical opening and closing method, which has a slow clamping speed and affects work efficiency. Utility Model Content
