Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an LC composite element suitable for use as a line filter element for protecting electronic circuit components such as OP'U, TTL, and 0-MOS from power line noise, and a method for manufacturing the same. It is.

Typically, Log combination components are made up of single coils and capacitors. Therefore, the number of parts is large and bulky, and connecting circuits in narrow spaces becomes a national problem.

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

In the figure, 1 is a winding core, 2.3D is an insulating film or paper, which is used as a dielectric material in the manufacture of capacitor elements. Then, one end side, that is, the winding start side end of the two stacked insulating film scraps is sandwiched between a sheet of electrode foil 47. The width, length, etc. of this electrode foil 4 are determined so as to have the required capacity of the foil-like coil to be formed, and lead wires 5a and 5b, which serve as both electrodes, are wound at both ends of this electrode foil 4. V is cut so as to protrude from one end side of the mating element. Two insulating films or papers sandwiching the electrode foil 4 are stacked and wound around the outer periphery of the υ-wound core 1 from one end thereof to form a foil coil II. Furthermore, between and above the two insulating films or papers, two electrode foils 7.8 are provided using these as dielectrics, and are wound concentrically around the outer periphery of the previously formed square coil. A capacitor O is formed by stacking them. Lead wires 66, 61) are provided protruding from each electrode foil 7, 8 of this capacitor. The capacitor lead wires 6a-s'b and the coil lead wires 5a, 51) are provided protruding from one side of the LO composite element configured as shown in the figure to facilitate connection to the electronic circuit later. However, the lead wires are not limited to those in the illustrated embodiment, and any markings may be made as necessary. In this way, one element has both the functions of a coil and a capacitor, but in order to protect its outer surface, it can be housed in an exterior case and filled with the composite value to form an integral mold, or it can be molded without using an exterior case. , directly apply a synthetic resin by dipping or the like to provide an exterior and make it durable for use.

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