Description

[Detailed Description of the Invention] This invention relates to a mounting structure for a switch rod used in electronic equipment such as a tuner, a cassette deck, and a tape recorder.

Conventionally, some switch rods used in electronic devices such as tuners, cassette decks, and tape recorders have bent front and rear ends as shown in FIGS. 1 to 3. That is, the switch rod 1' is equipped with a switch operation part 1'A having a slit 3 on the tip side into which the switch body 2 is fitted, and a knob 5 exposed from a front panel 4, which will be described later. It is formed by bending a knob operating portion 1'B on the rear end side in parallel to each other via a bending connection portion 1'C.

To install this switch rod 1', guide the switch rod 1', which has a knob 5 on the rear end side, into a mounting hole 6'A provided in a guide panel 6' that is attached to a chassis, etc. Insert from the front end of the panel 6'. After rotating the bending connection part 1'C in the mounting hole 6'A, insert it up to the knob operating part 1'B, and then fit the switch body 2 into the slit 3 provided at the tip of the switch rod 1'. Let them wear it. Thereafter, the front panel 4 is placed parallel to the guide panel 6' and the switch rod 1' is attached.
In this case, the position of the guide panel 6' is restricted relative to the switch rod 1', so that the front panel 4 can be easily attached without wobbling.

In this way, guide switch rod 1'.
It must be inserted from the front into the mounting hole 6'A of the panel 6'. Therefore, switch rod 1'
The horizontal dimension l' of the mounting hole 6'A provided in the guide panel 6' must be larger than the width of the guide panel 6'. This causes looseness between the switch rod 1' and the mounting hole 6'A of the guide panel 6'. - There was a drawback that the position of the switch rod 1' with respect to the panel 4 was not accurately regulated.

The present invention was developed in view of the above-mentioned drawbacks, and its purpose is to accurately control the position of the switch rod relative to the guide panel when the front panel is installed in front of the guide panel. Moreover, it is an object of the present invention to provide a mounting structure for a switch rod in an electronic device in which a front panel can be accurately positioned and mounted in front of a guide panel.

A first embodiment of the present invention will be described below with reference to FIGS. 4 to 8.

In this embodiment, the same parts as those of the conventional product shown in FIGS. 1 to 3 are designated by the same reference numerals.

Guide panels 6, 6 into which the switch rod 1 is inserted are formed at different levels. Reference numeral 6A denotes a mounting hole formed between guide panels 6, 6 at different levels, and this mounting hole 6A has a horizontal dimension l shorter than that of the conventional mounting hole 6'A shown in FIG. It is formed to have a step _l1 of arbitrary size in the front and back direction into which the switch rod 1 is inserted.

The first embodiment of the present invention has the above-mentioned configuration, and since the guide panels 6, 6 are arranged at different levels, the horizontal direction of the mounting hole 6A formed between the guide panels 6, 6 is The dimension l can be made shorter than that of the conventional products shown in FIGS. 1 to 3.

To install the switch rod 1 in this way, first insert the switch operating part 1A on the tip side into the mounting hole 6A.
(see Figure 4). Next, the switch rod 1 is tilted slightly as shown in FIG.
Insert the bent connecting portion 1C into the mounting hole 6A to connect the connecting portion B with the connecting portion 1C. In this case, mounting hole 6A
is formed between the guide panels 6, 6 which are formed at different levels as shown in FIG.
Although the horizontal dimension l is shorter than the conventional mounting hole 6'A shown in Figs. 1 to 3, since there is a step _l1 in the front-rear direction, it is easy to attach the switch operation part 1A.
The bent connecting portion 1B that is bent relative to the mounting hole 6A can be inserted into the mounting hole 6A.

Furthermore, although the bent connecting portion 1B is bent in the horizontal direction in the drawing with respect to the switch operation portion 1A on the distal end side, even if it is bent in the vertical direction at the same time, the bent connecting portion 1B can be easily inserted into the mounting hole 6A. can. Then, by inserting the linear knob operation part 1C straight into the mounting hole 6A, the guide
Insert the switch rod 1 into the mounting hole 6A of the panel 6 and set it. Then, insert the switch body 2 into the slit 3 provided at the tip of the switch rod 1.
Insert.

The mounting hole 6A formed between the guide panels 6, 6 is a conventional mounting hole 6'A shown in FIG.
Unlike, the horizontal dimension l is short and the switch
Since it is formed only slightly larger than the rod, it does not wobble even in the direction perpendicular to the axial direction. Therefore, even when installing the front panel 4, the switch rod 1 is attached to the guide panel 6.
As a result, the switch rod 1 can also control the mounting position of the front panel 4.

In addition, in the drawing, positioning protrusions 7A and 7B are provided on the left and right sides of the switch rod 1 and on the upper and lower surfaces orthogonal thereto along the axial direction thereof, and a guide recess is provided at a position orthogonal to the mounting hole 6A. By fitting the protrusions 7A and 7B into the mounting holes 6B and 6B so as to be able to slide freely, the switch rod 1 can be inserted into the mounting hole 6A without wobbling in the horizontal and vertical directions in the drawing. The switch rod 1 can be inserted into the mounting hole without any trouble.

What is shown in FIGS. 9 and 10 is a second embodiment of the present invention. This embodiment differs from the previous embodiment in that the guide panels 6, 6 are formed at different levels in the horizontal plane, and a mounting hole 6A is provided between the guide panels 6, 6.
This embodiment differs from the previous embodiment in that the mounting hole 6A is diagonally opened in the guide panel 6 in the same plane.

In addition, the bending connection part 1B of the switch rod 1
Although the switch rod 1 is only bent in the horizontal direction in the drawing, even if it is bent in the vertical direction, the mounting hole 6 can be opened by tilting the switch rod 1.
It can be easily inserted into A.

As mentioned above, in the present invention, the mounting holes of the guide panel are formed at different levels in the front and back direction to form mounting holes with short horizontal dimensions, so when the front panel is mounted in front of the guide panel, The position of the switch rod relative to the guide panel can be precisely regulated.In this way, the guide rod can be accurately positioned and installed relative to the guide panel. Can be accurately positioned and installed.
