Abstract
The utility model discloses a kind of soft magnetic core of improvement, comprise magnetic core intermediolateral column and be distributed in the magnetic core limit leg of described magnetic core intermediolateral column both sides.The window size of described soft magnetic core is 15.8mm, and the distance between the outside of the magnetic core limit leg of described both sides is 20.4mm.The height of described magnetic core intermediolateral column and magnetic core limit leg is 7.7mm.The diameter of section of described magnetic core intermediolateral column is 8.9mm.Distance between the upper surface of described magnetic core limit leg and the lower surface of magnetic core entirety is 10mm.The utility model is not changing on the integrally-built basis of magnetic core, distance between the outside of the magnetic core limit leg of both sides increases to 20.4mm by 20mm, realize magnetic core window size and become 15.8mm, increase the window size of magnetic core, the group number realizing secondary winding on magnetic core intermediolateral column increases, and meets the matching requirements of large gauge line bag.
Description
Technical field
The utility model relates to magnetic core technical field, especially relates to a kind of soft magnetic core structure for transformer.
Background technology
In order to increase the magnetic flux density of electromagnet, the magnetic conduction substance body arranged in the magnetic circuit of inductance coil is called magnetic core.Along with the increase of electronic product function, thus require the group number of the corresponding corresponding increase secondary winding of switching mode power supply transformer, and then requiring the most critical element as switching mode power supply transformer---magnetic core will have enough large window to increase winding to ensure that transformer has living space, and the window through calculating original EFD20 product cannot satisfy the demands.
As shown in Figure 1, be the structural representation of EFD20 magnetic core in prior art, EFD20 magnetic core comprises magnetic core intermediolateral column 1 and is distributed in the magnetic core limit leg 2 of magnetic core intermediolateral column 1 both sides, and line bag is arranged on magnetic core intermediolateral column 1.The window size 15.4mm of magnetic core shown in figure, the distance between the outside of the magnetic core limit leg 2 of described both sides is 20mm.The height of described magnetic core intermediolateral column 1 and magnetic core limit leg 2 is 7.7mm.The diameter of section of described magnetic core intermediolateral column 1 is 8.9mm.Distance between the upper surface of described magnetic core limit leg 2 and the lower surface of magnetic core entirety is 10mm.In order to meet the performance requirement of transformer, in prior art, EFD20 magnetic core can only configure the line bag of relative dimensions.When line bag specification expands, the window size of current magnetic core will seem less than normal, affects its assembly manipulation.
In order to adapt to the assembling compared with large gauge line bag, just needing the window size correspondingly increasing magnetic core, and adaptive adjustment is done to the overall structure of magnetic core, to meet the overall structure requirement of transformer.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, applicant is through repeatedly putting into practice improvement, devise a kind of soft magnetic core of improvement, do not changing on the integrally-built basis of magnetic core, increase the window size of magnetic core, the group number realizing secondary winding on magnetic core intermediolateral column increases, and meets the matching requirements of large gauge line bag.
Technical scheme: in order to realize foregoing invention object, the technical scheme that the utility model adopts is: a kind of soft magnetic core of improvement, comprises magnetic core intermediolateral column and is distributed in the magnetic core limit leg of described magnetic core intermediolateral column both sides.
The window size of described soft magnetic core is 15.8mm, and the distance between the outside of the magnetic core limit leg of described both sides is 20.4mm.
Further, the further technical scheme that the utility model adopts is: the height of described magnetic core intermediolateral column and magnetic core limit leg is 7.7mm.
Further, the diameter of section of described magnetic core intermediolateral column is 8.9mm.
Again further, the distance between the upper surface of described magnetic core limit leg and the lower surface of magnetic core entirety is 10mm.
Beneficial effect: compared with prior art, its beneficial effect is the utility model:
1, the utility model is not changing on the integrally-built basis of magnetic core, distance between the outside of the magnetic core limit leg of both sides increases to 20.4mm by 20mm, realize magnetic core window size and become 15.8mm, increase the window size of magnetic core, the group number realizing secondary winding on magnetic core intermediolateral column increases, and meets the matching requirements of large gauge line bag.
