Description
Technical field
The present invention relates to a kind of magnetic element, relate in particular to the magnetic element of the little and suitable assembling of a kind of volume.
Background technology
Generally speaking, standing in the electric equipment have many magnetic elements, as transformer, inductance element etc., and in order to adapt to the slimming of electric equipment, magnetic element and the inner conductive winding of using also must be towards the trend developments of slimming, to reduce the overall volume of electric equipment.
With the inductance element is example, existing inductance element is shown in Figure 1A, as shown in the figure, inductance element 1 is mainly by drum stand 11, magnetic core set 12 and coil 13 are formed, wherein, drum stand 11 has winding slot 111, use for coil 13 and twine thereon, also has consistent break-through road 112 in the drum stand 11, and the bottom of drum stand 11 has a plurality of pins 113, in order to be connected with coil 13, so that this coil 13 can be electrically connected with a circuit board (not icon), and magnetic core set 12 is an EE sections core, and have first magnetic core component 121 and second magnetic core component, 122, the first magnetic core components 121 and second magnetic core component 122 in the centre and two ends be respectively equipped with the center pillar 121a that homonymy protrudes, 122a and lateral column 121b, 122b.
When assembling inductance element 1, mainly the center pillar 121a of the center pillar 121a of first magnetic core component 121 and second magnetic core component is corresponded respectively to the penetrating via 112 of drum stand 11, and center pillar 121a, 122a be located in the penetrating via 112, and make the lateral column 122b corresponding assembling mutually of lateral column 121b with second magnetic core component 122 of first magnetic core component 121, by being arranged at coil 13 on the drum stand 11 and the electromagnetic induction between first magnetic core component 121 and second magnetic core component 122, make coil 13 produce induced voltage, and finish the inductance element 1 shown in Figure 1B.
Existing inductance element 1 is when the sensibility reciprocal of control electromagnetic induction, need distance between the center pillar 122a of the center pillar 121a by changing first magnetic core component 121 and second magnetic core component 122 to increase the air gap of inductance element 1, thereby reach the purpose of control inductance value, way now mainly is, with instrument center pillar 121a, 122a are pondered, fall certain volume with originally pondering, make center pillar 121a, 122a after pondering reduce length d than lateral column 121b, 122b with center pillar 121a, the 122a of lateral column 121b, 122b equal length
0(shown in Figure 1A), thus, when first magnetic core component 121 and second magnetic core component 122 were installed with to penetrating via 112, will have a length between center pillar 121a and the center pillar 122a was 2d
0Gap (figure do not show), this gap can be in order to adjust the inductance of inductance element 1, yet, existing inductance element 1 is when pondering center pillar 121a, 122a, can be subjected to the obstruction of lateral column 121b, 122b, make and to ponder comparatively difficulty of operation, especially darker when pondering when carrying out to center pillar 121a, 122a, often need expend more time because operation is difficult.
In addition, existing inductance element 1 is connected because the lateral column 121b of first magnetic core component 121 corresponds to each other with the lateral column 122b of second magnetic core component 122, thereby makes that the volume of inductance element 1 is very huge after assembling.This shows that existing technology is difficult to take into account the volume of reduced inductance element integral body and the manufacturing process of simplifying magnetic core set.
In view of this, how developing the manufacturing process that a kind of volume is little, can simplify magnetic core set, and can increase air gap, and can adjust the magnetic element of inductance value, to solve many shortcomings of prior art, is the problem of those skilled in the art's solution that presses at present.
