Technical field
The utility model relates to a kind of small inductor toroidal core inductance sorting unit.
Background technology
Small inductor toroidal core, especially ferrite core of nickel-zinc, single turn inductance value unit is in the nH rank, and existing electric inductance measuring-testing instrument can not directly be tested substantially; For testing its inductance and avoiding instrument and test error, need around the multi-turn plain conductor, usually more than 50 circles; After test is finished, the dismounting that will wind the line again, it is very inconvenient to test, and wastes time and energy, inefficiency, and has wasted a large amount of wires.
On July 11st, 2012, disclosed No. 201120445738.0 Chinese utility model disclosed a kind of annular magnetic core inductance separation tool; This sorting instrument comprises the toroidal core that is wound with plain conductor, the electric inductance measuring-testing instrument that links to each other with wire, metal column, metal platform, annular insulating boot, base etc.
This structure has the space because of toroidal core to be tested and metal column, and during test, along with the difference of each putting position, the inductance of toroidal core is also along with changing.Although after adopting said structure, the test inductance is about 10 μ H, the variable quantity of different putting positions then more than 1 μ H, accounts for more than 10% of inductance of test, and test error is large, so cause testing not accurate enough; The producer that has can be between the space of toroidal core and metal column increases the insulated hollow right cylinder, and reducing test error, but different toroidal core need be made different insulated hollow right cylinders, and also need be changed back and forth at every turn and preserve, and it is very inconvenient to use.
The utility model content
The technical problems to be solved in the utility model provide a kind of use simple, toroidal core test position to be measured is fixed, reduce test error, make more accurately small inductor toroidal core inductance sorting unit of test.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is as follows:
A kind of small inductor toroidal core inductance sorting unit comprises metab, is wound with toroidal core, electric inductance measuring-testing instrument, the metal column of plain conductor, and toroidal core is Magnetic Field Source; Metal column, metal cap, uncovered can contact, and jointly consist of the closed magnetic path; The uncovered can matches with annular insulating lid, metal cap cooperates with annular insulating lid is movable, metal column passes metal cap, annular insulating lid, toroidal core and uncovered can successively under upper, be provided with symmetrical groove and insulation projection on the described annular insulating lid radial surface, the insulation projection can slide along groove.
Above-mentioned small inductor toroidal core inductance sorting unit, described recess edge is provided with scale.
Above-mentioned small inductor annular magnetic core inductance separation tool is filled with insulating material between described toroidal core and the metal column.
Above-mentioned small inductor annular magnetic core inductance separation tool, described metal column is detachable the connection with metab.
The utility model is owing to adopted said structure, and the insulation projection can slide into magnet ring endocyclic position to be measured, and follow-up test can make each magnet ring to be measured position fix take this position as point of fixity, reduce test error, make test more accurate; This insulation projection can be adjusted according to magnet ring internal diameter size to be measured, uses so can adapt to the magnet ring test of different inner diameters, and is easy to use.
