Abstract
The utility model discloses a universal meter, which comprises a shell and a meter core arranged in the shell, wherein the meter core comprises a movable ring, a magnet and a bracket; the movable ring and the magnet are arranged on the bracket; and the bracket is made of an iron sheet. A buzzing switch-on and switch-off measurement device is arranged in the shell. The universal meter is light in weight, small in size, small in thickness, high in sensitivity and low in cost; and a requirement of general electricians on measurement can be met.
Description
Technical field
The utility model relates to a kind of electrotechnical measurement instrument, specifically a kind of multimeter.
Background technology
Current along with society's high speed development of electronic age; Electrotechnical measurement also generally develops to the digitizing direction, but traditional electric instrument is because it has simple in structure, cheap, indication advantage such as clear still is widely used among the every profession and trade commercial measurement.Now, mostly the analogue measurement multimeter is outer magnetic structure gauge outfit and common general inner magnetic structure.Factors such as the outer magnetic structure gauge outfit volume of cause is big, heavy, cost height; Make the development of multimeter develop to the direction of inner magnetic structure, and magnetic gauge outfit poor linearity in common, thickness is high; Can not satisfy the accuracy requirement of multimeter, it is portable also being not easy to product design simultaneously.
Summary of the invention
In order to overcome the problem that existing multimeter exists, the purpose of the utility model provides a kind of multimeter, this multimeter is in light weight, volume is little, thin thickness, highly sensitive, cost is low; And can satisfy general general electrotechnical measurement requirement.
The purpose of the utility model realizes through following technical scheme:
A kind of multimeter comprises housing and the watch core that is arranged in the housing, and it is characterized in that: said watch core comprises moving-coil, magnet and support, and moving-coil and magnet are arranged on the support, and said support is processed by iron sheet.
The utility model is provided with buzzing break-make measurement mechanism in housing.
The utility model is made up of universal circuit, adopts iron sheet support inner magnetic machine structure, the multimeter that obtains is in light weight, volume is little, thin thickness, be easy to carry, highly sensitive, cost low and can satisfy general general electrotechnical measurement requirement.This multimeter also has alternating current-direct current 10A Super-Current Measurement and buzzing break-make measurement function.
Description of drawings
Fig. 1 is the structural representation of watch core in the utility model.
Embodiment
A kind of multimeter comprises housing and the watch core 1 that is arranged in the housing, sees Fig. 1, and said watch core 1 comprises moving-coil 11, magnet 12 and support 13, and moving-coil 11 is arranged on the support 13 with magnet 12, and support 13 is processed by iron sheet.In housing, be provided with buzzing break-make measurement mechanism.
The utility model adopts in the iron sheet supporting structure magnetic watch core as the indicating mechanism of multimeter, and this mechanism is in light weight, cost is low, thin thickness, precision is high, the indication linearity is good.Multimeter volume with this watch core manufacturing is little, in light weight, indication is clear, gear is practical, range enriches, be easy to carry, cost is low, be convenient to batch process.
