Abstract
The invention discloses an inertia moving coil type electric sensor which comprises a casing, a mandrel, magnetic steel, a coil, a lead wire, spring pieces and a damping cup. The magnetic steel is fixed with the casing, the mandrel penetrates a central hole of the magnetic steel and supported on the casing through upper and lower spring pieces, the coil is fixed at one end of the mandrel, the copper damping cup is fixed at the other end of the mandrel, and the spring pieces are in shapes of spherical surfaces. The inertia moving coil type electric sensor has the advantages of being compact in structure, low in output impedance, good in anti-interference performance and the like.
Description
Technical field
the present invention relates to sensor design technical field, relate in particular to a kind of inertia-type moving-coil type electrodynamic transducer.
Background technology
utilize electromagnetic induction principle, movement velocity is converted to the sensor of the induced potential output in coil, claim again inductosyn, the work of this sensor does not need additional power source, but directly draw the mechanical energy of testee and convert electric signal output to, for the induction of measuring dither, need to have much room for improvement.
Summary of the invention
The object of the present invention is to provide a kind of inertia-type moving-coil type electrodynamic transducer, compact conformation, output impedance is low, strong interference immunity.
To achieve these goals, the present invention adopts following technical scheme:
A kind of inertia-type moving-coil type electrodynamic transducer, include housing, mandrel, magnet steel, coil, lead-in wire, spring leaf and damping cup, described magnet steel and housing are fixed together, described mandrel is through the center pit of magnet steel, and be supported on housing by upper and lower two flat spring sheets, one end of mandrel is fixed with coil, and the other end is fixed with copper damping cup.
Affiliated spring leaf is dome shape.
Beneficial effect of the present invention:
The advantages such as the present invention has compact conformation, and output impedance is low, strong interference immunity.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Wherein: 1-housing; 2-mandrel; 3-magnet steel; 4-coil; 5-lead-in wire; 6-spring leaf-7-damping cup.
