Description

[Detailed explanation of the invention] [Summary] This is a structure in which multiple data channel transformers are mounted adjacently on a printed circuit board, in order to prevent deterioration of circuit characteristics due to mutual interference of magnetic lines of force generated from adjacent transformers. The circuit characteristics are improved by arranging the lines of magnetic force so as to be orthogonal to each other and reducing mutual interference of the lines of magnetic force.

[Industrial application field]

The present invention relates to a data channel transformer mounting structure, and more particularly to a data channel transformer mounting structure that reduces mutual interference of magnetic lines of force.

In recent years, there has been a strong demand for smaller and lighter electronic devices in general, and in order to satisfy these demands, electronic components have been forced to be mounted in high density. If the magnetic field lines are placed in parallel, the lines of magnetic force will interfere with each other.

[Prior Art] FIG. 2 is a diagram illustrating the mounting structure of a conventional data channel transformer, in which a is a plan view of the main part and b is a plan view of a distributed arrangement.

Figure 2a shows a plurality of (two in the drawing) transformers 2 and 3 on the printed circuit board 1 of the data channel.
When the lines of magnetic force 4 are mounted adjacent to each other in parallel, the lines of magnetic force generated from the transformers 2 and 3 have an elliptical shape, and the longitudinal direction, that is, the width portion of the ellipse overlaps, and the area of mutual interference is the hatched part 5. It grows like this.

FIG. 2b shows a transformer 2 on a printed circuit board 1,
In order to avoid mutual interference of the lines of magnetic force generated from the magnetic field lines, the magnetic field lines are distributed in a dispersed manner.

[Problem that the invention attempts to solve]

In the conventional data channel transformer mounting structure described above, multiple transformers are mounted so that their lines of magnetic force are parallel, so that some of the lines of magnetic force (the part shown by hatching in Figure 2a) overlap each other. Since they interfere with each other and deteriorate the characteristics of the circuit, there is a problem in that distributing them (FIG. 2b) hinders high-density packaging.

[Means for solving problems]

In order to solve the above problems, the present invention provides a data channel transformer mounting structure that reduces mutual interference between magnetic lines of force generated from adjacent transformers.

That is, the problem is solved by mounting a plurality of data channel transformers 2 and 3 adjacent to each other on the printed circuit board 1 so that the lines of magnetic force 4 of the adjacent transformers 2 and 3 are orthogonal to each other. .

[Effect]

In the data channel transformer mounting structure, adjacent transformers are orthogonally arranged and arranged at equal intervals, thereby reducing the mutual interference area of magnetic lines of force generated from the transformers and improving circuit characteristics.

〔Example〕

FIG. 1 is a plan view of essential parts for explaining an embodiment of the present invention, and parts equivalent to those in FIG. 2 are given the same reference numerals.

In the figure, a plurality of (two in the drawing) transformers 2 and 3 are installed on the data channel printed circuit board 1.
When mounted so that the lines of magnetic force 4 are perpendicular to each other, the lines of magnetic force 4 generated from the transformers 2 and 3 have an elliptical shape. overlaps with the center in the width direction, so the mutual interference area 6
becomes small like the hatched part.

In this embodiment, two transformers are mounted, but the present invention is also applicable to two or more transformers.

[Effect of idea]

As is clear from the above description, according to the present invention, the mutual interference area is reduced, circuit characteristics are improved, and the present invention is extremely effective for high-density packaging.
