Description

[Detailed Description of the Invention] The present invention relates to a capacitor, and in particular, it is an object of the present invention to provide a capacitor which has good productivity and wiring work, and which can be manufactured simply and easily with various capacitances.

Hereinafter, one embodiment of the present invention shown in FIGS. 1 to 4 will be described. Reference numeral 1 indicates a case made of an insulating material, and the case includes an opening 2, a hollow portion 3, a bottom plate portion 4, and ,
Several recesses 5 are formed on the inner wall of the hollow portion 3 so as to span the bottom plate portion 4 .

6... is a chip-shaped capacitor formed by forming electrodes 8, 8 on both sides of a dielectric material 7 such as ceramic, 9...
. . . is a terminal plate made of electrodynamic material and has a contact portion 10 that contacts the electrode 8 and a pull-out portion 11; 12 is a pressing member made of a screw or the like; the pressing member is screwed into the hollow portion 3 of the case 1;
Alternatively, it can be attached by press fitting.

Next, the assembly of the capacitor of the present invention will be explained. First, one terminal plate 9 is housed in the hollow part 3 of the case 1,
The drawer part 11 is aligned with the recess 5 of the case 1 and led out from the bottom plate part 4, and the contact part 10 is overlapped on the bottom plate part 4.

Next, the chip capacitor 6 is inserted into the hollow part 3 of the case 1 so that one electrode 8 is brought into contact with the terminal plate 9.

Next, another terminal board 9 is housed in the hollow part 3, the lead-out part 11 is matched with the other recess 5, and it is led out through the bottom plate part 4, and the contact part 10 is connected to the chip-shaped capacitor. 6 on the other electrode 8.

After the terminal plates 9 and the chip capacitors 6 are alternately housed in the case 1 in this way, the pressing member 12 is screwed or press-fitted into the hollow part 3 of the case 1, and the terminal plates housed in the case 1 are 9 and the chip-shaped capacitor 6 are pressed toward the bottom plate portion 4 to complete the assembly.

In the embodiment of the present invention shown in FIG. 1, five chip capacitors 6 are used, and the circuit diagram thereof is as shown in FIG. Furthermore, the present invention can be applied to a tuning capacitor C1, a coupling capacitor C2, a feedback capacitor C3, and bypass capacitors C4 and C5 of a modified clamp type oscillation circuit used in a 1M tuner or a television tuner.

Further, in the present invention, the number of chip-shaped capacitors 6 is not limited to five, but can be configured with an appropriate number, and furthermore, the number of chip-shaped capacitors 6 provided between adjacent terminal plates 9 is limited to one. Not only can the capacitance value be varied by stacking two or three of them in an appropriate number, but
The number of terminal plates 9 is also 1 between adjacent chip capacitors 6.
It is not limited to the number of individual capacitors, but a plurality of capacitors can be stacked to provide a plurality of external connections.Furthermore, the case 1 and the chip capacitor 6 can be arbitrarily changed in shape, such as circular or polygonal.

That is, according to the present invention, a plurality of chip capacitors 6 are housed in the hollow part 3 of the insulating case 1, the drawer part 11 is led out of the case 1, and the contact part 10 is connected to the chip capacitor 6. Since the terminal plate 9 is housed in contact with the electrode 8 of the terminal plate 9, and the terminal plate 9 and the chip-shaped capacitor 6 are pressed by the pressing member 12, the assembly is extremely easy and the productivity is good. In addition, an appropriate number of chip-shaped capacitors 6 and terminal boards 9 can be assembled as needed, and therefore, various capacitance values and any number of external connections can be easily obtained. In addition, various practical effects such as better wiring work can be achieved.
