Description

[Detailed explanation of the idea] The present invention relates to a multiple volume.

In conventional multiple volume controls, each volume has the same type of terminal, such as a printed circuit board connection type terminal, a wire wrapping type terminal, or the like.

However, in the case of a multi-volume volume in which each volume has a terminal connected to a printed circuit board, the circuit patterns corresponding to each volume are concentrated near the volume because they are mounted on the printed circuit board, resulting in performance deterioration and damage to the printed circuit board. There was a problem that the area could not be used effectively.

Additionally, multiple volume controllers in which each volume has wire-wrapped or wire-soldered terminals cannot be fixed to a printed circuit board, which increases the number of man-hours required for wiring, and also causes problems such as circuit wiring becoming tangled and deteriorating performance. Ta.

It is an object of the present invention to solve these conventional problems and to provide a multiple volume that can improve electrical performance and make effective use of printed circuit boards.

The present invention will be explained in detail below based on the illustrated embodiments.

FIG. 1 shows an embodiment of a double volume.

VR□. VH2 is a single volume, VRl is a volume having a printed circuit board connection type terminal 1, and VH2 is a volume having a wire wrapping type terminal 2.

This multiple volume is installed on the printed circuit board P by connecting the terminal 1 of the volume VR1 to one circuit pattern on the printed circuit board P, and is assembled in a part of the printed circuit board P away from the volume mounting part. A lead wire 4 pulled out from a wrapping terminal 3 of another circuit pattern is wound around the terminal 2 of the volume VR2.

If the volume VR2 is also fixed to the printed circuit board P by providing a fixed leg 5 (indicated by an imaginary line in the figure), the entire fixation will be made more stable.

Figure 3 shows an example of a four-volume volume, ■R1, VR2
is a volume having a printed circuit board connection type terminal 1, VH3
, VH2 is a volume having a wire wrapping type terminal 2.

In this case, two circuit patterns corresponding to the volumes VR1 and VR2 are placed near the volume mounting part of the printed circuit board P, and the other two volumes VR are placed in a part away from this.
3. A circuit pattern corresponding to VR1 is provided, and the wire wrapping type terminals 2, 2 and the wrapping terminal (not shown) of each circuit pattern are connected by lead wires.

Incidentally, in the above two embodiments, a multiple volume is shown in which a volume having a printed circuit board connection type terminal and a polyurethane having a wire wrapping type terminal are combined, but a wire soldering type terminal is used instead of a volume having a wire wrapping type terminal. It is also possible to use a volume having the following values.

As described above, the present invention is a multiple volume that is a combination of a volume having a printed circuit board connection type terminal and a volume having a wire wrapping type or wire soldering type terminal, so that the circuit pattern corresponding to each volume is printed on the printed circuit board. It is not necessary to concentrate the circuits in the volume mounting area when installing the volume, which simplifies the design of the printed circuit board, prevents interference between each circuit, and particularly improves channel separation. Instead of having wire wrapping type or wire soldering type terminals, some of the volumes have printed circuit board connection type terminals, so they can be attached to a printed circuit board and the number of lead wires can be reduced. This makes assembly and wiring easier by avoiding the entanglement.
