Abstract

The invention discloses a method and a device for rapidly testing fusing characteristics of a meltof a filament fuse, and belongs to the field of electronic components. The test method comprises a fuse meltfusing time test method, a fuse finished product fusing time test method, a melt cold state resistance value test method and a fuse finished product cold state resistance value test method. During testing, the fuse wire is tensioned by the spring for testing, wherein the test includes a moderate overload test and a high overload test when the fuse takes air or a shell as a dielectric layer and takes an arc suppression material or the shell as the dielectric layer. The testing device comprises a testing device base, a hanging frame, a left clamp, a left clamp fixing seat, a right clamp, a differential sliding table and a gear sliding table. The problems that only semi-finished product or finished product testing can be carried out on an existing filamentous fuse, time and materials are consumed, checking is carried out afterwards, the production efficiency is low, and the cost is high are solved. The method and device are widely applied to the field of testing of fuse melt materials.

Description

technical field [0001] The invention belongs to the field of electronic components, and further relates to the field of fuses, in particular to a rapid testing method and testing device for the fusing characteristics of filamentary fuses. Background technique [0002] In electronic circuits, in order to protect the circuit itself, fuses are usually used for overvoltage and overcurrent protection of the circuit. The key characteristic of the fuse is mainly the fusing characteristic, which is an important indicator parameter for the overcurrent protection of the fuse connected to the circuit. Therefore, accurate testing of its fusing characteristic is the key to ensure that the fuse can effectively protect the circuit. At present, domestic wire fuse manufacturers usually test the fusing characteristics of fuse products by testing their semi-finished products or finished products to monitor the research and development or production of fuses. Although this method can evaluate ...
