Abstract

PURPOSE:To obtain a radio-frequency elimination transformer by alternately stack-winding an insulator and a conductor on a magnetic iron core and composing a static capacity element by the winding and static portions of the conductor. CONSTITUTION:A synthetic resin film insulator 19a and a conductor 20a made by evaporating Al, Cu, etc. on a synthetic resin film insulator with its width substantially equal to that of the insulator 19a are stacked up. Depending upon a required static capacity element the insulator 19a and the conductor 20a are selected in length and area. Electrodes 21a, 21b and 21c are each connected with the cutoff layer portions of conductors 20a and 20b. Most of the conductors 20a, 20b comprise a transformer winding, and input terminals 24a, 24b and output terminals 25a, 25b are connected with the left and right ends of both conductors, i.e., 22a, 22b and 23a, 23b, respectively. The conductors are wound on a magnetic iron core 10.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transformer, and in particular comprises a conductor made of a synthetic resin film deposited with aluminum, copper, etc.
This invention relates to a transformer in which the length of the conductor is appropriately cut to form a winding element and a capacitance element to remove high frequencies.

Transformers generally consist of copper and aluminum conductors wound around a magnetic core.
It converts high voltage to low voltage and low voltage to high voltage.

When using such a transformer in a power supply circuit that uses high frequencies such as a television receiver, video, etc., the transformer's primary winding or secondary winding 1 must be
A capacitive element for IsK high frequency removal was connected separately.

Therefore, installation work such as soldering is required to attach the capacitive element, and this installation requires a mounting location.

The present invention is an improved transformer to eliminate the above-mentioned drawbacks, and the present invention is a transformer in which the winding is made of a synthetic resin insulating film, aluminum or copper vapor-deposited, and an insulating film in two or three layers. The electrodes are formed by stacking layers, and a part of the vapor-deposited film is cut to form an electrode, thereby obtaining a capacitive element and a transformer for removing high frequency waves.

An actual example of the present invention will be described below with reference to the drawings.

FIG. 1 is an electrical circuit showing the overall structure and configuration.

In the figure, a magnetic core 10 is wound with a primary winding 11 and a secondary winding 12, the details of which will be described later. Attached to this - arrow line 11 are two capacitance elements 13 and 14 connected in series, the details of which will be described later.

Further, a capacitance element 16, a resistor 17, and a capacitance element 18, the details of which will be described later, are attached to the secondary winding 12 via a rectifier 15 connected by Brigge.

In these electric circuits, the electric circuits of the first block A and the second block B shown by dashed lines are constructed by each element shown in FIG.

FIG. 2 shows the main parts of the first and second blocks of the electrical circuit of FIG. That is, there is an insulator 19a made of a synthetic resin film, and an insulator made of aluminum or copper on the insulator made of a synthetic resin film of approximately the same width on the outside of this insulator 19a. 19a and conductor 2
0a means an appropriate length and conductors 20a, 20
As b, at the front end, rear end, or middle part, static 2
Electrodes 21a, 21b, and 21e are connected to 0d and 20e.

Also, most of the conductors 20a and 20b have a length that constitutes the coil of the transformer, and the left and right ends 2 of both conductors are
2a*22b, 23a, 23bVcU input terminal 24a
, 24b and output terminals 25a, 25b.

These capacitance elements and transformers are constructed by forming two layers of conductors 20a, 20b and insulators 19a, 19b, cutting them to appropriate lengths, and then cutting the conductors 20a, 20b into electrodes -f.
Connect the terminals 21a, 21b, 21eTh to the kh 20c, 20d, 20e, and then connect the input terminal 20a to both terminals of the conductive (4) bodies 20a, 20b.

20b, output terminals 25a, 25bt- are connected and wound around the magnetic iron core 10.

Alternatively, it is also possible to attach a pre-wound one to the magnetic core 10 (C).

Next, how to use the illustrated transformer will be explained.

Terminals 24a and 24b' of the primary winding 11 are connected to the power supply side of the transformer.

Therefore, the output terminals 25 a , 25 of the secondary winding 12
b is transformed into a voltage according to the turns ratio, and is connected to rectifier 1.
5 to obtain a DC voltage. This DC voltage is then rectified by electrode 2.
The high frequency component is removed by a capacitive element consisting of 0c, 20d, and 20elh, and the output terminal 25a.

At 25b, a DC power source from which high frequencies are removed can be obtained. The pφ power for this purpose can be effectively used as a power source for timers, inverters, and the like.

In this circuit, when a high frequency wave enters the power supply side, it is routed to the ground side by the capacitance element on the input side, and is rarely introduced to the input power supply.

Furthermore, since the conductor 20a #20b as a winding is formed by full metal vapor deposition, the resistance value can be changed depending on the thickness of the vapor deposition and the material, and the current can be limited depending on the purpose of use. can.

As explained above, the transformer of the present invention is capable of stacking the primary and secondary windings in two layers and winding them all at once using a conductor and an insulator. Since both conductors face each other in the section, a capacitive element of any capacitance can be obtained by adjusting the entire area.

Therefore, it is easy to manufacture the transformer, and the capacitance can also be formed integrally through this winding operation, so the input side of the transformer is connected to the output side separately for high frequency removal. I can't even connect to it.

In addition, since the resistance value of the conductor can be selected, there is an advantage that various power transformers can be made smaller and have fewer parts.
