One side between two ring surfaces being oppositely arranged and the outer peripheral edge being connected to this two ring surface, described side
It is parallel with first annular groove and lay respectively at this that middle part is provided with multiple first annular groove be arrangeding in parallel at equal intervals
Two the second cannelures of a little first annular groove both sides and vertical with first annular groove and the second cannelure and etc.
Multiple pods of spaced and parallel setting.
Preferred version is, the interval between described each first annular groove be adjacent to less than the second cannelure the
Interval between one cannelure.
Preferred version is, described side is respectively equipped with line outlet groove in the position at the two ends near ring surface, described
Four wire holes it are provided with at equal intervals in line outlet groove.
Preferred version is, each ring surface is first-class is interval with four grooves, and between the most adjacent two grooves
Form a boss, parallel on each boss be provided with multiple bar-shaped trough at equal intervals.
Preferred version is, the groove that the two ends of each bar-shaped trough are adjacent respectively communicates, and relative to boss
Centrosymmetry arrange.
Preferred version is, the shape of the form and dimension of the cross section of described boss and the cross section of groove and big
Little identical, each groove and boss are straight flange in the limit near through hole, and around the outer peripheral face formation one of through hole
Octagon.
The invention have the benefit that
Insulator in the present invention is silicon nitride insulator, and thermal coefficient of expansion is low, especially polysilicon, works as temperature
When degree raises, temperature drift is less likely to occur the measurement signal of coil；Simultaneously as insulator is provided with interval
Different first annular groove, the second cannelure and pods, easily facilitates the coiling of coil groups, makes and allocate,
Meanwhile, make coil convenient relative to position adjustments succinct, measurement signal can be regulated by fine setting, it is ensured that measure
Precision so that assembling positioning precision is high.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, be fully described by, it is clear that described embodiment be only a part of embodiment of the present invention rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation
The every other embodiment obtained under property work premise, broadly falls into the scope of protection of the invention.
As it is shown in figure 1, this insulator 100 is applied in an array induction apparatus for coiling.This insulation
Body 100 is ceramics insulator, specially silicon nitride ceramics insulator.This insulator 100 is cylindric, its
Center is provided with the through hole 10 of a circle.This insulator 100 includes two ring surfaces 20 being oppositely arranged and connects
One side 30 between the outer peripheral edge of this two ring surface 20.
Each ring surface 20 is first-class is interval with four grooves 21, and is formed between the most adjacent two grooves 21
One boss 22.The shape of the form and dimension of the cross section of described boss 22 and the cross section of groove 21 and big
Little identical.Each groove 21 and boss 22 are straight flange in the limit near through hole 10, and around through hole 10
Outer peripheral face forms an octagon.The side of the through insulator in outside 100 of each groove 21 and boss 22
30.The degree of depth everywhere of each groove 21 is identical；Each boss 22 height everywhere is identical.Each boss 22
Upper the most parallel it is provided with multiple bar-shaped trough 23, the groove that the two ends of each bar-shaped trough 23 are adjacent respectively at equal intervals
21 communicate, and arrange relative to the centrosymmetry of boss 22.
Described side 30 is provided with multiple first annular groove 31 and two second parallel with first annular groove 31
Cannelure 32.The most parallel middle part being located at side 30 of described first annular groove 31, and with insulator 100
Ring surface 20 parallel.Described two second cannelures 32 lay respectively at the both sides of these first annular grooves 31,
And in arranging near the position of ring surface 20.Interval between described each first annular groove 31 is less than the second ring
Interval between the first annular groove 31 that shape groove 32 is adjacent to.Described side 30 is near ring surface 20
Two ends and the position of a corresponding boss 22 be respectively equipped with a line outlet groove 33, in described line outlet groove 33 at equal intervals
It is provided with four wire holes 330.Each wire hole 330 in each line outlet groove 33 at grade, and with one
Second cannelure 32 at grade, to guide by the wire drawn in line outlet groove 33.
