Description
Technical field
The utility model relates to a kind of inductance device, particularly a kind of rigid line simplex winding common mode inductance vertical unit, and it is the common mode inductance vertical unit of a kind of energy by big electric current." vertical " mentioned is meant that the axial line in the magnet ring center of circle is vertical with the plane of installation.
Background technology
At present, general current density is smaller or equal to 400A/cm
2The common mode inductance horizontal type device, be to adopt to allow lead pass from magnet ring, the structure of fixing cord and magnet ring respectively again.Along with the power of all kinds of power modules (as AC adapter AC/DC, DC converter DC/DC, inverter DC/AC etc.) is increasing, the current density of lead is also increasing, and is also will the differentiate cross-sectional area also increasing.The stumpy lead that will pass from magnet ring, not only threading and fixing difficulty, and also it is also big to take up room, and is difficult to realize the miniaturization of product structure.And if to guarantee the quality of product, will improve the manufacturing seating means, thereby cause its processing technology complexity.
Summary of the invention
The purpose of this utility model is, proposes and design a kind of rigid line simplex winding common mode inductance vertical unit, the problem that exists with the traditional structure that solves big electric current common mode inductance.
Technical solution of the present utility model is: comprise magnet ring and single core rigid line winding, it is characterized in that described magnet ring has one or more; Single core rigid line winding has two groups, adopts two copper bars to pass magnet ring respectively and forms, and between two copper bars at the center of passing magnet ring insulation board is housed; The magnet ring that printed circuit board list core rigid line winding and insulation board are housed is installed on the printed circuit board, and the axial line in the center of circle of magnet ring is vertical with the plane of printed circuit board.
It is characterized in that two copper bars are same member.
It is characterized in that two copper bars pass magnet ring respectively, and with being connected of printed circuit board, adopt the filling of insulating cement to fix magnet ring.
It is characterized in that an end of two copper bars symmetry respectively passes the center of magnet ring and printed circuit board and printed circuit board and fixes, an other end of two copper bars is stayed the outer and printed circuit board of magnet ring and is connected.
The utility model has the advantages that, novel, reasonable in design, simple in structure, safe in utilization, can pass through big electric current effectively, and easy for installation.

Embodiment
Below, with reference to the accompanying drawings, describe embodiment of the present utility model in detail.
As shown in Figure 1, the device of existing traditional common mode inductance, wherein lead passes from magnet ring.Lead is rounded.To pass lead just very difficult and be not easy to fix along with volume increases many round conductors.
As Fig. 2, shown in Figure 3, the utility model has adopted magnet ring 2, and by two groups of single core rigid line windings that two copper bars 1,4 constitute, magnet ring adopts high-permeability material to make.Two copper bars 1,4 are processed into identical shaped member, three magnet ring 2 levels stack, combine, in three magnet rings 2, two copper bars 1 and an end of 4 respectively symmetry to pass the center of magnet ring 2 and printed circuit board 5 and printed circuit boards 5 fixing, two copper bars 1 and an other end of 4 are stayed the outer and printed circuit board 5 of magnet ring 2 and are connected.The axial line in the center of circle of magnet ring 2 is vertical with the plane of printed circuit board 5.An end of copper bar 1,4 that passes the center of magnet ring 2 is equipped with insulation board 3 each other, and two copper bars 1,4 that constitute two groups of single core rigid line windings are kept apart.Stay the termination of two outer copper bars 1 of magnet ring 2 and an other end of 4 and be connected with supporting terminal on the printed circuit board 5, copper bar 1 and 4 two ends are connected with fixedly magnet ring 2, insulation board 3 present positions printed circuit board 5.Copper bar 1 and 4 sectional area size have determined the current characteristics of common mode inductance.Adopt insulating cement to fill magnet ring 2, fixedly magnet ring 2.Magnet ring 2 can use one or more as required.
Above content be in conjunction with concrete execution mode to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
