Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a switch knob device for electronic equipment such as a cassette tape recorder.

Conventional technology In recent years, electronic products have become smaller and thinner, and as a result, the internal components and switches have also become smaller, and more and more importance has been placed on their appearance and operational feel. .

An example of a conventional switch knob device will be described below with reference to the drawings. FIG. 4 shows a conventional switch knob device. 1 is a cabinet. Reference numeral 2 denotes a printed circuit board, which is fixed to the cabinet 1 with screws 3.
4 is a switch connected to the printed circuit board 2. 5 is a switch knob, and by pushing it in the direction of arrow A, switch 4 is switched.

Problems to be Solved by the Invention However, in the above configuration, clearances a, b, and c shown in FIG. It also has a negative impact on Also, switch 4 is fixed on printed circuit board 2.
This is done using screws, which is very disadvantageous when configuring it inside smaller and thinner products.

In view of the above-mentioned problems, the present invention eliminates the play between the cabinet and the switch knob, reduces the size of the switch knob device so that it can be configured inside a small and thin product, and allows easy installation and removal of the device from the cabinet. The present invention provides a switch knob device that can perform the following functions.

Means for Solving the Problems In order to solve the above problems, the switch knob device of the present invention includes a knob part that switches the switch by a hinge effect, a holding part that holds the switch,
It is composed of a hook portion that engages with a locking portion provided on the cabinet.

Effects The present invention solves the following problems with the above-described configuration. Since the switch knob is directly attached to the cabinet and can be switched using a hinge effect, play between the cabinet and the switch knob can be eliminated, and since the switch is held by the switch knob, the switch can be fixed and held even in a small space. Additionally, the switch knob is attached to the cabinet using a snap-in method, making it easy to attach and remove.

Embodiment A switch knob device according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a cross section of a switch knob device according to an embodiment of the present invention. 11 is the main body cabinet;
12 is a subcabinet. 13 is a switch held by a holding part 14a of a switch knob 14, and when the knob part 14b is pushed in the direction of arrow A, the hinge part 14c is deflected and the switch 13 is switched. The switch knob 14 is the hook part 1
4d and 14e are the locking parts 1 of the main body cabinet 11
1a and 11b, respectively.

The mounting structure of the switch knob device configured as described above will be explained below. In FIG. 2, reference numeral 15 denotes a flexible printed circuit board to which the switch 13 is connected, and is inserted into the switch knob 14 in the direction of arrow B. Next, in FIG. 1, first fit the hook portion 14d of the switch knob 14 into the lock portion 11a of the main body cabinet 11, and then bend the hook portion 14e to engage the lock portion 11b. and fix it. As described above, according to this embodiment, there is no play between the switch knob and the main body cabinet.
Holding and fixing the switch becomes reliable and easy. Further, when the switch is to be removed, the switch can be removed simply by pressing the hook portion 14e of the switch knob 14 and bending it. Furthermore, by providing a protruding portion 14f from the switch knob 14 as shown in FIG. 3, electrical components such as the LED 16 can be held and positioned.

Effects of the invention As described above, the present invention provides a switch knob with a knob part that switches the switch by a hinge effect, a holding part that holds the switch, and a hook part that engages with a locking part provided on the cabinet. This eliminates play between the cabinet and the switch knob, allows the switch to be held and fixed easily and securely, allows the switch knob device to be made smaller, and is very effective in configuring the interior of smaller and thinner products.
