Description

[Detailed description of the invention] This invention relates to a control device for operating parts such as a volume control and a switch used in a radio receiver, etc., and it is possible to easily and inexpensively move the control parts such as a control panel and a switch that are directly attached to a printed circuit board from the front of the cabinet. The purpose is to enable operation using a knob.

Generally, printed circuit boards are often mounted with the foil side facing the front of the cabinet in order to adjust electrical components placed on the board and to improve serviceability. Therefore, operating parts such as volume controls and switches are often mounted directly on the cabinet and connected to the printed circuit board using lead wires. Therefore, with this type of product, it is necessary to connect the operating parts attached to the cabinet and the printed circuit board using lead wires, which increases the number of parts and makes it difficult to assemble the operating parts and printed circuit board to the cabinet. , it was not very favorable economically.

On the other hand, when operating parts such as a volume control or switch are mounted directly on a printed circuit board, the printed circuit board must be placed at right angles to the front of the cabinet, which has through-holes for operation, in order to adjust the electrical components mounted on the board. As a result, the depth of the cabinet increases, making it difficult to reduce the thickness of the cabinet.

This project eliminates the above-mentioned drawbacks of the conventional method, and uses a jumper wire soldered to a printed circuit board as a support shaft, and a separate lever for operation is attached.
This lever is used to directly operate operating parts such as a volume and a switch.

The operating device of the present invention will be described below with reference to drawings of an embodiment.

FIG. 1 is a partially cutaway perspective view of an embodiment of the operating device according to the present invention. In the figure, 1 is a printed circuit board, which is mounted with its foil side facing the cabinet 2 side. A slide switch 3 has an operating shaft 4 on its side.

Reference numeral 5 designates an operating lever, which has a substantially U-shaped engagement portion 11 at one end that engages with the operating shaft 4 of the slide switch, and has a hole 6 for a support shaft near the center. Furthermore, the operating lever 5 is attached to pass through a through hole 8 provided in the printed circuit board 1, and a jumper wire 7 soldered across the through hole 8 is inserted into the hole 6 for the support shaft. Therefore, the operating lever 5 can be pivoted about the jumper wire 7 as a support shaft. Reference numeral 9 indicates a through hole for operating a knob provided in the cabinet 2, and reference numeral 10 indicates a knob attached to the operating lever 5.

2 and 3 are a perspective view and a side view of main parts showing another embodiment. In this case, a cylindrical pipe 12 is fitted to the jumper wire 7, and the cylindrical pipe 12 is used as a support shaft for operation. The lever 5 is pivotally supported. The operating lever 5 uses the cylindrical pipe 12 as a support shaft.
If it is pivoted so that it can swing freely, the swinging fulcrum can be stably and easily separated from the printed circuit board by the radius of the cylindrical pipe, and it can be moved that much closer to the operating shaft 4 of the slide switch 3, making the operating stroke of the knob easier. Can be expanded. This is Cabinet 2
This is particularly advantageous when the distance between the control lever 5 and the printed circuit board 1 is regulated to be small and the knob 10 side of the operating lever 5 cannot be extended. In this case, the jumper wire itself is also reinforced, making it mechanically stronger. When attaching the knob, instead of attaching the knob 10 directly to the operating lever 5 as shown in FIG. 1, as shown in FIG. It is also possible to provide a slide-type knob by providing a knob 14 slidably attached to the cabinet 2 and engaging the shaft 15 formed on the knob 14 with the engaging portion 13.

Note that the support shaft jumper wire 7 may also be used for electrical wiring.

In this case, as described above, the operating lever 5, which is attached through the printed circuit board 1 which is attached to the front of the cabinet with the foil side facing, is supported by the jumper wire 7 or the cylindrical pipe 12 fitted to the jumper wire 7. The lever 5, which is swingably mounted, is configured to operate switches and other operating parts 3 directly mounted on the printed circuit board, and the operating parts are directly mounted on the printed circuit board and electrically connected. Therefore, even if the printed circuit board is mounted with the foil side facing the front of the cabinet, lead wires are not required, which increases the number of parts due to connection using lead wires, and worsens the workability of assembling operating parts and printed circuit boards into the cabinet. There isn't. Further, since the printed circuit board can be attached to the cabinet so that the foil side of the printed circuit board faces the front surface of the cabinet, the dimension in the depth direction of the cabinet is small and the cabinet can be made thinner. Moreover, the operating lever is supported by a jumper wire that passes through the printed circuit board and is attached to the printed circuit board, and one end is connected to the operating shaft of the operating component that is directly attached to the printed circuit board, and the other end is connected to the operating shaft of the operating component that is directly attached to the printed circuit board. Since it protrudes from the operating hole on the front surface of the cabinet, the operating parts directly attached to the printed circuit board can be operated using the knob on the front surface of the cabinet without increasing the depth of the cabinet.
