1, can't make the elementary winding on the internal magnetic ring be evenly distributed on the regulation zone, often squint;
2, internal magnetic ring location difficulty in insulation crust causes the position of primary coil in whole transformer to be difficult to control;
3, the secondary coil on the shell is few owing to the number of turns, and adopts the manual mode coiling, is difficult to reach the requirement of even coiling, and finally causes the discreteness of the primary coil and the secondary coil degree of coupling bigger, and the control difficulty of electric property (especially leakage inductance) is bigger.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of prior art; Providing a kind of can be controlled at elementary winding in the regulation zone uniformly; Can effectively locate, effectively control the position deviation between primary coil and the secondary coil, reduce the annular isolation transformer of the discreteness of electric property.
Technical scheme: in order to realize above purpose, a kind of annular isolation transformer of the present invention comprises: internal magnetic ring, inner casing and shell; Internal magnetic ring is fixed in the inner casing, and said shell card covers on the outside of inner casing; Said internal magnetic ring lateral surface is provided with at least two internal magnetic ring positioning boss; Said inner casing is inboard to be provided with the internal magnetic ring location notch with internal magnetic ring positioning boss opposite position; Said internal magnetic ring after the coiling is fit in the inner casing, and said internal magnetic ring positioning boss snaps in the location notch of inner casing.The present invention is evenly distributed in regulation zone through the internal magnetic ring positioning boss with elementary winding through at the internal magnetic ring lateral surface internal magnetic ring positioning boss being set; Overcome the difficulty that to locate elementary winding on the internal magnetic ring; Internal magnetic ring positioning boss and the inboard internal magnetic ring location notch of inner casing is used on the while internal magnetic ring; Internal magnetic ring is fixed on the position that requires of inner casing; Locate simple and conveniently, the position of primary coil in whole transformer fixed, improved the consistency of electric property.
The outside of shell described in the present invention is provided with the shell positioning boss; Said inner casing exterior bottom and shell positioning boss opposite position are provided with the shell location notch; When said shell and inner casing assembling, the shell positioning boss snaps in the shell location notch; The shell positioning boss on the shell and the shell location notch of inner casing exterior bottom are interlocked and have realized the relative fixed of inner casing and shell, have realized the location of inner casing and shell, shell is fixed on is difficult for skew, good stability on the inner casing.
Be provided with shell secondary pole coiling locating piece at said outer casing top surface among the present invention, the number of shell secondary pole coiling locating piece is confirmed through the number of turns of the coil that twines on the shell; When secondary coil twines; The copper wire that constitutes secondary coil snaps between shell secondary pole coiling locating piece and the shell secondary pole coiling locating piece; Through even distribution and the location that shell secondary pole coiling locating piece has been realized secondary coil, reduced the discreteness of electric property (particularly leakage inductance).
Inner casing described in the present invention is provided with elementary winding lead-out groove and elementary winding leading foot; The said annular isolation transformer case outside is equipped with the protection blade that is used to protect transformer.
Beneficial effect: the present invention compared with prior art has the following advantages:
1, the present invention makes the elementary winding on the internal magnetic ring be evenly distributed in the regulation zone through the internal magnetic ring positioning boss that is provided with on the internal magnetic ring, and deviation does not take place;
Effective location of 2, having realized internal magnetic ring and inner casing through the internal magnetic ring positioning boss that is provided with on the internal magnetic ring and the internal magnetic ring location notch on the inner casing among the present invention; Position deviation between control primary coil and the secondary coil, the annular isolation transformer of the discreteness of reduction electric property;
3, through shell positioning boss and shell location notch inner casing and shell are effectively located among the present invention, improved the stability of transformer;
The even distribution and the location of 4, having realized secondary coil through shell secondary pole coiling locating piece among the present invention have further reduced the discreteness of electric property (particularly leakage inductance).
