Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a LOO composite element suitable for use as a line filter element for protecting electronic circuit components such as CPUXTTL and 0-MOS from power line noise. Since the circuit is made up of a combination of single coils and capacitors, it has a large number of components and is bulky, making it difficult to connect the circuit in narrow spaces.

In view of this, the present invention applies the conventional manufacturing method of capacitor elements to simultaneously wind the coil t around the center of the capacitor to form an integral structure, so that one element has both the functions of a coil and a capacitor. The present invention will now be described based on the illustrated embodiments.

In the figure, 1 is a winding core, and 2 and 3 are insulating films or paper, which are used as dielectric materials in the production of capacitor elements. And one of these two layers of insulating film or paper at one end, that is, the beginning of the roll? The electrode foil 4 is sandwiched between the electrode foils 4 and 4. The width, length, etc. of this electrode foil 4 are determined so as to have the required capacity of the foil coil to be formed, and the t
Lead wires 5a and 5b, which serve as both electrodes, are provided at both ends of the passive drive 4 so as to protrude toward one end of the composite element to be wound and formed. Two insulating films or papers sandwiching the electrode foil 4 are stacked and wound around the outer periphery of the P-winding core 1 from one end thereof to form a foil coil 'L'. In addition, two electrode foils 7.8 are provided between and above the two insulating films or papers, using these as dielectrics, and are wound concentrically around the outer periphery of the previously formed coil. A capacitor C is formed. Lead wires 6a and 6b are provided protruding from each electrode foil 7.8 of this capacitor, respectively. The capacitor leads 6a and 6'b and the coil lead m5
A and 5b are provided protruding from one side of the IIC compensation element configured as shown in the figure to facilitate connection to the electronic circuit later, but these lead wires are limited as in the illustrated embodiment. It may be provided so as to protrude in any direction without being fixed. Furthermore, markings shall be placed on each lead wire to distinguish between coils and capacitors, if necessary.

Next, after concentrically winding the capacitor around the outer periphery of the coil, the winding core 1 is removed, and the ferrite core 10 is inserted into the winding core hole 9 formed at the center. In this way, one element has both the functions of a coil and a capacitor, but in order to protect the outer surface of the IC, it can be housed in an external case and integrally molded with synthetic resin, or an external case can be used. First, a synthetic resin is applied directly by dipping or the like to provide an exterior covering to make it durable for use.

According to the present invention, the coil is wound and formed in the same way as the conventional capacitor manufacturing method, and the capacitor is also wound and formed concentrically around the outer circumference, so that the coil and the capacitor are formed simultaneously in one element. Therefore, it has advantages such as easy manufacture and low bulk, making it easy to incorporate into electronic circuits.
