Description

one

The invention relates to electrical engineering, is a choke in a hybrid-film design, intended for use in circuits with both printed and volumetric wiring.

The purpose of the invention is to improve the specific-dimensional characteristics of the throttles and increase its reliability.

FIG. 1 shows one side of the printed conductor board; FIG. 2 shows a board with a magnetic core enclosing it; on fig.Z - assembled choke, top view; figure 4 is the same, side view.

A choke consists of a board 1, on which the conductors 2 are made on two sides by the method of printed wiring. Figure 1 shows the board 1 on one side only, since there are similar conductors on the other side. An insulating layer 3 is located over the conductors 2. A closed insulated core 4 encloses the conductors 2 on both sides of the board 1. Each conductor 2 is connected in series with the adjacent conductor 5 located on top of the magnetic core 4. Thus, on both sides of the board two about 1203606

It operates with the electric field of the two windings. The assembly (receiving) of the windings from the semi-windings is performed by soldering (or welding) the ends of the conductors 5 with printed half-windings. Moreover, the semi-turn of the conductors 5 can be performed in the form of a finished comb and be welded by wave soldering at one time to the printed half winding, which increases the productivity of the assembly work and the reliability of the thrusts.

Applying two coils to the circuit board allows the inductance to be quadrupled (proportional to the square of the turns), since two times more turns are placed on one board on both sides.

The core is wound onto a printed circuit board and shorted to it, i.e., the entire magnetic field is closed through the electric field of both coils.

Thus, the magnetic characteristics of the core are maximally used, 20 since the entire core body in the proposed construction works in the creation of an electromagnetic field. This also leads to an increase in inductance of 1.2 times. As a result, the proposed design allows to obtain an inductance of 3.5 times

These windings are then connected electrically (in parallel or in series) through terminals 6. In this way, a choke with two windings and with a closed magnetic core of a core structure is obtained, i.e. the magnetic field of the interaction 30

Also, the proposed construction, made on the same board with printed semi-windings, allows to obtain the height of the throttles (the main parameter for microcircuit) not more than 3 mm.
