The invention discloses a low-inductance annular magnetic core inductance sorting tool, which comprises a metal base, an annular magnetic core, an inductance tester and a metal post, wherein the annular magnetic core is wound with metal conducting wires and is a magnetic field source, the metal post, a metal cover and an uncovered metal box are in contact and jointly form a closed magnetic circuit, the uncovered metal box is matched with an annular insulation cover, the metal cover is movably matched with the annular insulation cover, the metal post sequentially passes through the metal cover, the annular insulation cover, the annular magnetic core and the uncovered metal box from top to bottom, holes are formed in the side edge of the uncovered metal box, and the metal conducing wires wound on the annular magnetic core are allowed to pass through the holes. Through the adoption of the structure, the height of the metal cover is decreased, the weight is reduced, and the testing operation is more labor-saving and is more convenient; and the holes are formed in the side edge of the uncovered metal box, so that the metal conducting wires can be fixed and do not need to be replaced to and fro and wound repeatedly, and in addition, the service lives of the metal conducing wires are prolonged.
Description
Technical field
The present invention relates to a kind of small inductor toroidal core inductance sorting instrument.
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 leads.
Disclosed No. 201120445738.0 China's invention on July 11st, 2012 (calling documents in the following text) disclosed a kind of toroidal core inductance sorting instrument; 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 lead, metal column, metal platform, annular insulating boot, base etc.
This structure can be finished the inductance sorting of small inductor toroidal core substantially, but in use, because of metal cap height height, Heavy Weight, each test needs metal cap is taken off, puts back to operation from metal column; After the long-time test, tester's hand can be felt to ache, swelling.
In addition, when metal cap was closed, the plain conductor on magnet ring of can rubbing back and forth came off insulation course, needed often to change and coiling plain conductor again, used inconvenience.
Summary of the invention
The technical problem to be solved in the present invention provides and a kind ofly can make that plain conductor is fixed, metal cap weight is lighter, operates more laborsaving, the instrument of small inductor toroidal core inductance sorting easily.
For solving the problems of the technologies described above, technical scheme provided by the invention is as follows:
A kind of small inductor toroidal core inductance sorting instrument, comprise metab, be wound with toroidal core, electric inductance measuring-testing instrument, the metal column of plain conductor, described toroidal core is Magnetic Field Source, and described metal column, metal cap, uncovered can contact, and constitute closed flux path jointly; The uncovered can matches with annular insulating lid, and metal cap cooperates with annular insulating lid is movable, and described metal column passes metal cap, annular insulating lid, toroidal core and uncovered can successively under last.
Above-mentioned small inductor toroidal core inductance sorting instrument, described metal column is detachable the connection with metab.
Above-mentioned small inductor toroidal core inductance sorting instrument, described uncovered can side has the hole, allows the plain conductor of coiling on the toroidal core to pass.
Above-mentioned small inductor toroidal core inductance sorting instrument, fill insulant between described toroidal core and the metal column.
After the present invention adopted said structure, the metal cap height reduced, weight saving, operated more laborsaving, convenient; The perforate of uncovered can side can make plain conductor fix, and does not need to change back and forth and coiling plain conductor again, and has prolonged the serviceable life of plain conductor.
Description of drawings
Fig. 1 is the structural representation of small inductor toroidal core inductance sorting instrument of the present invention.
Wherein have: 1. metab; 2. metal column; 3. be wound with the toroidal core of plain conductor; 4. electric inductance measuring-testing instrument; 5. metal cap; 6. annular insulating lid; 7. uncovered can; 8. magnet ring to be measured; 9. hole.
Embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
A kind of small inductor toroidal core inductance sorting instrument, comprise metab 1, be wound with toroidal core 3, electric inductance measuring-testing instrument 4, the metal column 2 of plain conductor, described toroidal core 3 is Magnetic Field Source, and described metal column 2, metal cap 5, uncovered can 7 contact, and constitute closed flux path jointly; Uncovered can 7 matches with annular insulating lid 6, metal cap 5 and annular 6 movable cooperations of insulating lid, and described metal column 5 passes metal cap 5, annular insulating lid 6, toroidal core 3 and uncovered can 7 successively under last.
After adopting said structure, described toroidal core 3 be Magnetic Field Source, can from described electric inductance measuring-testing instrument 4 read a value, i.e. the truth of a matter, the common truth of a matter need be the bigger the better.
Before the use, need the limit of the specification up and down toroidal core by manual coiling test, in small inductor toroidal core inductance sorting instrument of the present invention, test, with test value as standard value.
During use, annular magnet ring 8 to be measured is placed on the annular insulating lid 6, closed metal cap 5, can from electric inductance measuring-testing instrument 4 read a new displayed value, this displayed value and standard value are compared, can judge whether this toroidal core to be measured qualified.
Compare with documents, the metal cap in the documents is split as metal cap 5 and uncovered can 7 in the present invention, has highly reduced half, and correspondingly volume reduces, and weight has also alleviated more than 1/3rd, and the tester is also just more laborsaving in use; The metal cap volume reduces, also easier grasping.
Small inductor toroidal core inductance sorting instrument of the present invention, described uncovered can 7 sides have hole 9, allow the plain conductor of coiling on the toroidal core 3 to pass.Further, because plain conductor can fixedly pass from hole 9, the plain conductor that just can not rub is not worried coming off of insulation course on the plain conductor, does not need to change back and forth and coiling plain conductor again, thereby has prolonged serviceable life of plain conductor.
Small inductor toroidal core inductance sorting instrument of the present invention, described metal column 2 is detachable the connection with metab 1.Can change the metal column 2 of appropriate length according to the height of magnet ring to be measured; Also can the metal column 2 of wearing and tearing be keeped in repair and change, thereby prolong serviceable life of this sorting instrument.
Further, small inductor toroidal core inductance sorting instrument of the present invention, fill insulant between described toroidal core 3 and the metal column 2 can make toroidal core 3 fixing, does not rock, and it is more accurate, reliable to test, and this toroidal core 3 is difficult for taking place disrepair phenomenon.
