Abstract
The utility model discloses a magnetic core shell of a flux gate sensor probe, comprising an excitation coil magnetic core shell and an induction coil magnetic core shell, wherein the two magnetic core shells are made of soft plastic thin slices and can house a magnetic core, the shape of the magnetic core shell is in a transverse I shape after symmetrically folding the shell along a midline of a developing view and a copper wire is wound on the two magnetic core shells. The way of sleeving different magnetic cores by magnetic core shells for producing flux gate sensor probes with uniform external factors of the magnetic cores such as wire winding and edge distance replaces the traditional method for producing a plurality of independent flux gate sensor probes, so as to conquer the inevitable external parameter fluctuation among different flux gate sensor probes.
Description
Technical field
The utility model relates to a kind of magnetic core shell of magnetic flux door sensor probe.
Background technology
Fluxgate sensor (being designated hereinafter simply as fluxgate) is used to measure low-intensity magnetic field, has the resolution height, measurement range is wide, reliability is high, simple in structure, economy and durability, can directly measure characteristics such as magnetic-field component.The critical component of fluxgate is a fluxgate magnetic core, partly is made up of magnetic core, drive coil, magnetic test coil etc.Nowadays the research of fluxgate obtains paying attention to gradually; Many scientific research personnel study fluxgate; Can run into many problems unavoidably under study for action, for example when research the influencing of core material, generally all be identical drive coil and the magnetic test coil of coiling on the magnetic core of unlike material or different tissues state, same size; Influence parameter with outside the fixed magnetic core other; But different magnetic cores are attend the physical dimension of the coil of institute's coiling, and the tightness of coiling etc. there are differences inevitably, thereby interference experiment result.In addition,, need to be equipped with the probe of a plurality of different magnetic cores, have above-mentioned problem equally for adapting to different application scenarios.
The utility model content
The purpose of the utility model is to provide a kind of magnetic core shell of magnetic flux door sensor probe.
The basic ideas of the utility model are: have the mode that the unified fluxgate magnetic core shells of magnetic core external factor such as coiling, back gauge come the different magnetic cores of suit with making; Replace making the classic method of a plurality of independent probes, overcome the inevitable external parameter fluctuation that exists between the different probes.
The magnetic core shell of a kind of magnetic flux door sensor probe that the utility model provided; Form by drive coil magnetic core shell and two magnetic core shells of inductive coil magnetic core shell; Two magnetic core shells are processed by the nonrigid plastic thin slice; Can entangle magnetic core, the magnetic core shell shape is the I shape that behind the center line symmetrical fold of stretch-out view, is traverse, is wound with copper cash on two magnetic core shells.
Said magnetic core shell is used for the movable magnetic core of suit unlike material.
Copper cash 100～200 circles that said magnetic core shell coiling diameter is 0.15～0.25mm.
Described magnetic core shell adapts to the magnetic core of unlike material, different length, and magnetic core ties in shell, can fixed magnetic core, be difficult for squinting.
Described magnetic core shell can be made a plurality of different shells, to satisfy the requirement of different external parameters.
Described magnetic core shell is used for the movable magnetic core of suit unlike material.Can the cover holding position of shell be adjusted according to the different back gauge requirement of when research, have very big dirigibility.
Described magnetic core shell is processed by the nonrigid plastic thin slice, and it is shaped as the I shape of traverse.In the coiling process, coiling receives the restriction on right sides edge, can guarantee that coil edge is neat, can act on magnetic core fully to guarantee inductive coil and drive coil, and even action, and monnolithic case is fixed simultaneously, and is not easy to wear, reduces the influence of external parameter fluctuation.
I shape ghost at described magnetic core shell is around with copper cash 100～200 circles that diameter is 0.15～0.25mm.Select the less copper cash coiling of diameter for use, help making the magnetic core shell coiling of producing neat, and can coiling more coil number under the same size shell, thereby satisfy the requirement of different drive coils and number of inductive coil turns.
The method for making of the said magnetic core shell of the utility model has following steps:
(1) according to the physical dimension of magnetic core, design the stretch-out view of probe magnetic core shell, and on the nonrigid plastic thin slice, draw, accurately cut down again;
(2) along the center line symmetrical fold of stretch-out view, interior folder magnetic core;
(3) behind the alignment edge, in the middle of the I shape plastics neatly, equably successively around on copper cash, between adjacent two layers, the copper cash coiling of staggering;
(4) after coiling finishes, the fixedly copper cash that applies glue, treat glue curing after, extract magnetic core out, form the multi-function magnetic core housing.
The beneficial effect of the utility model is: make a fluxgate multi-function magnetic core housing, through the magnetic core of interior cover unlike material, can study different heat treatment mode, different-thickness; The different edge distance; Different length has been eliminated the influence of coiling difference to the influence of probe characteristic, has reduced the workload of making fluxgate magnetic core; Used control variate method neatly, for studying and even using and all brought very large convenience.

Embodiment
First rectangle of on the nonrigid plastic plate, drawing, specification is 11mm*20mm, is respectively second, third rectangular long limit with these rectangular two minor faces again; Symmetry this two small rectangles that draw in first rectangle, specification is 7mm*3mm, draws the 4th rectangle in first rectangular midline simultaneously; Specification is 6mm*7mm; Being located at first rectangular middle, cutting the shape of having drawn then, is the axis of symmetry doubling with the center line; Form I shape, obtain the I shape model.The magnetic core of making is put in the middle of the I shape model, and like this, model is being wrapped up in the magnetic core outside, and two outshot is a confinement block; The model center section begin neatly equably successively around on copper cash, the coiling of staggering between the adjacent two layers copper cash is whenever around one deck copper cash; Note checking frequently whether the magnetic core degree of tightness is suitable, guarantee the copper cash coiling closely, evenly, when reaching the coil number that needs; Applying glue fixes copper cash, extracts magnetic core out, has accomplished the making of the magnetic core shell of a magnetic flux door sensor probe.
