Description

The big electric current SMD of slimming induction structure

Technical field

The utility model relates to the big electric current SMD of a kind of slimming induction structure, be particularly related to the inductance component of a kind of SMD of being applied to (surface mount design), can laterally wind the line for the line group by main core, with reach a kind of can fast and convenient manufacturing and tool slimming, low clearance SMD inductance be purpose.

Background technology

The existing SMD induction structure that is used for the big electric current of slimming, see also shown in Figure 1, described SMD inductance 1 comprises unshakable in one's determination 10, line group 11 and ring cowling 12 are formed, wherein, described unshakable in one's determination 10 is to be the I-shaped shape, described line group 11 is with more than described unshakable in one's determination 10 the center pillar 100 minimum circles of vertical coiling storehouse, each extends the weld part 12A that described ring cowling 12 1 sides 120 are located in weldering 11 liang of end lines of described line group, 12B, described again ring cowling 12 covers cover described unshakable in one's determination 10, form SMD inductance 1 part, and see through the weld part 12A of described ring cowling 12 1

sides

120,12B and circuit board (figure does not show) connect, when making a kind of inductance component for surface mount technology (SMD) use, the fabricated part of described again SMD inductance 1 total height below 1mm, described I-shaped shape iron core 10 highly equals the described sum total that height that pendulum 101 thickness add center pillar 100 adds the bottom 102 thickness that goes up, take a broad view of, when vertical winding line group 11 on described center pillar 100, but the line group 11 of its winding storehouse is height-limited in the height of described center pillar 100, described again unshakable in one's determination 10 go up puts 101, the thickness of the bottom 102 is too thin, the artificial coiling is difficulty relatively, and described unshakable in one's determination 10 center pillar 100 winding modes can't pick up from motivation device processing mode, need the collocation manual operation, when the manual operation manufacturing tolerance, easily cause described unshakable in one's determination 10 upward pendulum 101, the bottom 102 breakages, thereby cause described unshakable in one's determination 10 fracture, and described again unshakable in one's determination 10 center pillar 100 is height-limited, the coil number of its winding is limited, the number of turns of its required winding ratio again, process technology be difficulty relatively;

The shortcoming of prior art:

1. existing SMD induction structure, the thickness of the upper and lower pendulum of described iron core is thin excessively, cracky during the artificial coiling.

2. manpower processing is loaded down with trivial details, can't fast and convenient manufacturing production.

3. yield is low, and manufacturing cost can't reduce.

Therefore, how providing a kind of can laterally wind the line for the line group by described main core, with reach a kind of can fast and convenient manufacturing and tool slimming, low clearance SMD inductance be purpose, effectively control its stabilised quality, and then reach the saving manpower and improve yield, be the place of the technical difficulties of this case inventor institute desire solution.

Summary of the invention

The purpose of this utility model is to provide the big electric current SMD of a kind of slimming induction structure, can solve above-mentioned problems of the prior art.

To achieve these goals, the utility model provides the big electric current SMD of a kind of slimming induction structure, and it comprises: ㄇ female cap sheet, and it is the square shape body that is ㄇ shape, with the cemented one that is of main core; Main core is established the left side pendulum of vertical configuration and the right side pendulum of vertical configuration, and described left pendulum is established horizontal center pillar indirectly with right pendulum, horizontal winding line group on the center pillar of described main core; The line group, on the center pillar that laterally is set around described main core, described line group is respectively extended two end lines and described main core left and rightly accommodates side weld part weldering and establishes.

Can laterally wind the line for the line group by described main core, with reach a kind of can fast and convenient manufacturing and tool slimming, low clearance SMD inductance be purpose.

Advantage of the present utility model:

1. process fast and Stability Analysis of Structures, production capacity and quality promote relatively.

2. the utility model is adopted horizontal winding mode manufacturing, and described part can meet and reaches slimming, highly low requirement, and the automatic facility of can arranging in pairs or groups are produced in a large number.
