Description

Sampler of integrated fuse Technical Field The utility model relates to the technical field of electronic products, in particular to a sampler integrated with a fuse. Background In the field of electronics, a sampler is one of the important components. The utility model discloses an electric bicycle surplus mileage number display system among the prior art, the authority bulletin number is CN200944133Y, and it includes electric motor car battery, sample thief, power management chip, mileage conversion module, outage memory module, display module and display terminal. The power management chip obtains the residual electric quantity parameter of the storage battery through sampling of the sampler, the mileage conversion module converts the residual electric quantity parameter into a drivable mileage and sends the drivable mileage to the display module, the display module is communicated with a display terminal arranged on the surface of the electric vehicle, the display terminal accurately displays the mileage of the electric vehicle, which can be powered by the residual electric quantity, and the display terminal can be a pointer meter or a nixie tube and the like. The power management chip and the mileage conversion module are connected with the power-off memory module, so that the stored data can not be lost under the condition of stopping power supply. As known from this prior patent, the sampler is an important component for detecting the battery charge parameter. In order to ensure safety, many samplers are configured with fuses, but users often cannot know the state of the fuses in time in the use process, so that the overhaul and the investigation are not facilitated. Disclosure of utility model The utility model aims to provide a sampler integrated with a fuse, which solves the problems in the prior art.
