Abstract
The present invention relates to a kind of stairstepping inductance coil winding method being applied to inductance sensor, the cylindrical framework including stairstepping coil and supporting coil and coil set, wherein stairstepping coil divides three sections to carry out coiling, and coil set is arranged on the position of fixed coil on coil；Use close around method coiling design the number of plies after one end hookup wire snare I of coil I, then coiling II；Hookup wire snare II, finally use close around method coiling III, the top of online snare II and coil III is wrapped up two-layer alkali-free glass fiber cloth and is fixed.The inventive method can make wire winding displacement neat, can well keep original shape, improves the inductance sensor linearity, improves certainty of measurement.
Description
Technical field
The present invention relates to a kind of inductance coil method for winding, relate to inductance sensor field, particularly relate to one and be applied to
The stairstepping inductance coil winding method of inductance sensor.
Background technology
Inductance coil is the vital part in inductance sensor, the inductance of inductance coil when the magnetic core of coil inside moves
Can change, can be obtained the displacement of magnetic core by the change of perception coil inductance, magnetic core is generally connected with gauge head, enters
And the displacement of gauge head can be obtained.Can form a magnetic field after coil electricity, preferable magnetic field is uniform, the electricity of such coil
Inductance value change keeps good linear relationship with the displacement energy of magnetic core, but due to the synergistic effect of coil magnetic field, causes coil
Middle region is due to by the produced magnetic field superposition of the right and left coil, thus the magnetic field of coil zone line is relatively by force, coil
The magnetic field of two end regions is more weak.So coil inductance change is not linear when portion moves magnetic core in coil, Jin Erying
Ring sensor performance, reduce certainty of measurement.
For solving the problems referred to above, the present invention proposes a kind of stairstepping inductance coil coiling side being applied to inductance sensor
Method, coiling forms the magnetic field of an approaches uniformity, and the method can make wire winding displacement neat, can well keep original shape,
Improve sensor linearity and improve certainty of measurement.
Summary of the invention
It is an object of the invention to provide a kind of stairstepping inductance coil winding method being applied to inductance sensor, the party
Method proposes a kind of winding method for the inductance coil feature of inductance sensor, can improve sensor linearity, improve and measure essence
Degree.
For achieving the above object, the present invention uses technical scheme to be a kind of stairstepping inductor wire being applied to inductance sensor
Circle winding method, the method includes the most several step: (a) use in cylindrical framework close around the method coiling design number of plies
Bottom coil；B () is at the top hookup wire snare I of coil I and coiling II；(c) online snare I and the top of coil II
Hookup wire snare II and coil III；D it is entered by () online snare II with the top parcel two-layer alkali-free glass fiber cloth of coil III
Row is fixing.
Compared with tradition winding method, the inventive method can make wire winding displacement neat, can well keep original shape, change
The kind inductance sensor linearity, raising certainty of measurement.
Accompanying drawing explanation
Fig. 1 is stairstepping inductance coil winding method schematic diagram
In figure: 1, coil I 2, coil II 3, coil III 4, cylindrical framework 5, coil set I 6, coil set II 7, alkali-free glass

Specific implementation method
So that below in conjunction with accompanying drawing, the invention will be further described.
It is illustrated in figure 1 stairstepping inductance coil winding method schematic diagram, comprises the steps:
(a) use in cylindrical framework 4 close around method coiling design the number of plies coil I 1.
B () is at the top hookup wire snare I 5 of coil I 1 and coiling II 2.Choose the position in the middle of skeleton to pacify
Wiring snare I 5, remote position coiling II 2；Coil II use close around method to carry out coiling；The thickness of coil set I 5
Spending equal with the thickness of coil II 2, its computing formula is [n-0.134 (n-1)] d, and in formula, n represents the number of plies of coiling, d
Represent the line footpath of coil.The internal diameter of coil set I 5 adds the thickness of coil I 1 equal to the radius of skeleton.
The top hookup wire snare II 6 of (c) online snare I 5 and coil II 2 and coil III 3.Choose in the middle of skeleton
Hookup wire snare II 6 is carried out in position, remote position coiling III 3, coil III 3 use close around method carry out coiling；Line
The thickness of snare II 6 is equal with the thickness of coil III 3, and its computing formula is [n-0.134 (n-1)] d, represents coiling in formula n
The number of plies of coil, d represents that the line footpath of coil, the internal diameter of coil set II 6 add coil I 1 and coil II 2 equal to the radius of skeleton
Thickness.
D it is fixed by () online snare II 6 with the top parcel two-layer alkali-free glass fiber cloth 7 of coil III 3.
Above-described embodiment, simply presently preferred embodiments of the present invention, not be used for limiting the scope of the present invention, therefore all with this
The equivalence change that content described in invention claim is done, within all should being included in scope of the invention as claimed.
