Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a click mechanism for a rotary electric component with a click mechanism.

[Conventional technology]

5 and 6 are explanatory diagrams of a conventional example. FIG. 5 is a sectional view of a rotary variable resistor with a click mechanism, and FIG. 6 is a plan view of a click plate.

In FIG. 5, 1 is a rotating shaft, 2 is a bearing, 3 is a click plate that rotates together with the shaft 1, and the click plate 3
As shown in FIG. 6, on the surface thereof, there are a plurality of first click grooves 4 on the same circumference and second click grooves 5 provided at predetermined positions. 5 is formed deeper than the first click groove 4. 6 is a slider holder that rotates together with the click plate 3; 7 is a slider fixed to the slider holder 6; 8 is a slider holder that rotates together with the click plate 3;
9 is a resistor board, 9 is a leaf spring non-rotatably held between the bearing 2 and the resistor board 8, and the arm 1 of the leaf spring 9 is
0 is in elastic contact with the surface of the click plate 3 provided with the first and second click grooves 4 and 5. 11 is a case of the variable resistor, and 12 is a terminal connected to the end of the resistor on the resistor board 8, whose illustration can be omitted.

By rotating the shaft 1, the click plate 3 rotates together, the arm 10 of the leaf spring 9 engages and disengages from the first click groove 4, and the slider 7 moves into the resistor with the same click feeling. When the arm 10 of the leaf spring 9 engages with the second click groove 5 while sliding on the resistor on the board 8, a stronger click feeling is activated than when the arm 10 of the leaf spring 9 engages with the first click groove 4. The slider 7 is configured to sense that the slider 7 has reached a predetermined position.

[Problem that the invention attempts to solve]

However, as parts become smaller, the click plate 3 is naturally also made smaller, and the distance between the first click groove 4 and the adjacent second click groove 5 becomes closer, making it impossible for each to provide an independent click sensation. Instead, they interfere with each other, reducing the difference in sensation between when the arm 10 of the leaf spring 9 engages with the first click groove 4 and when it engages with the second click groove 5.
This has the disadvantage that it is difficult for the operator to sense when the slider 7 has reached the desired position on the resistor.

The present invention aims to solve the above-mentioned conventional drawbacks, and the purpose of the present invention is to provide a small multi-contact switching rotating electric component that allows an operator to easily sense a predetermined rotational position. The purpose of this invention is to provide a click mechanism for rotating electronic components that can be used.

[Means for solving problems]

In order to achieve the above objectives, the present invention
A first click groove, a click plate provided with a second click groove having a different depth from the first groove at a predetermined location, and a first click groove that engages and disengages the first and second click grooves. , a leaf spring provided with a second arm, the first and second arms of the leaf spring are engaged with and disengaged from the first and second click grooves, respectively, and the leaf spring has different lengths. A rotary electric component is provided with first and second arms, and the click plate has a first click groove and a second click groove arranged so as to be shifted in the radial direction,
The surface on which the first and second click grooves are formed is arranged with a step.

[Effect]

The present invention has the above-described structure, and when the click plate rotates due to the rotation of the rotating shaft, the first plate spring
The arm of the leaf spring engages and disengages from the first groove of the click plate to give the same click feeling, and when the second arm of the leaf spring engages the second groove of the click plate, a click feeling greater than the above click feeling is generated. A tactile sensation is provided, allowing the operator to clearly sense that the shaft has reached a predetermined position.

In addition, since the surface on which the first click groove is formed and the surface on which the second click groove is formed are arranged with a step and shifted in the thickness direction of the click groove, when assembling, the leaf spring and the click plate are separated. Even if the relative positional relationship is slightly shifted, the two click mechanisms will not interfere.

Note that the same parts as in the conventional example shown in FIGS. 5 and 6 are designated by the same reference numerals, and detailed explanations will be omitted. The differences between the conventional example shown in FIGS. 5 and 6 and the embodiment of the present invention are the structure of the leaf spring 13 and the click plate 1.
4, this point will be explained in detail below. In FIG. 2, 13 is a leaf spring, 15 is a central hole, and 16 is an arc-shaped cut groove provided on the upper outer periphery of the hole 15, and the outer periphery of the hole 15 and the inner periphery of the cut groove 16 are connected. In between, the first arm 17 is cut and raised. Reference numeral 18 denotes an arc-shaped kerf formed in the opposite direction of the groove 16, and the outer periphery of the groove 15 and the kerf 1

It is formed longer than 9.

In FIG. 3, reference numeral 14 denotes a click plate, and an oval-shaped hole 22 into which the oval-shaped portion 1a of the shaft 1 fits is formed in the center. 23 is a plurality of first click grooves formed on the same circumference from the center o' of the hole 22;
Reference numeral 24 denotes a second click groove 24 extending radially inward from the first click groove 23 and provided at a predetermined location. A flat portion 25 is formed. Further, the first arm 17 of the leaf spring 13 corresponds to the first click groove 23, and the second arm 19 corresponds to the second click groove 24. As shown in FIG. 4B, the surface on which the second click grooves 24 are formed is one step higher than the surface on which the first click grooves 23 are formed.

When the shaft 1 is rotated in FIG. 1, the bulge 20 of the first arm 17 of the leaf spring 13 and the first click groove 23 of the click plate 14 are repeatedly engaged and disengaged, and the click plate 14 rotates. The second arm 19 of leaf spring 13 provides the same click sensation to the actuator, but
When the bulging portion 21 of the slider 7 fits into the second click groove 24 of the click plate 14, the operator is given a click feeling larger than the above-mentioned click feeling, and the operator feels that the slider 7 is on the resistor board 8. It is possible to sense that the resistor is located at a predetermined location.

According to the embodiment of the present invention, the click plate 14 is provided with a plurality of first click grooves 23 on the same circumference, and the second click grooves 23 are provided at predetermined locations inside the click grooves 23.

Even if the diameter of the click grooves 23, 24 of the click plate 14 from the center o' becomes smaller as the product becomes smaller, the two click mechanisms work independently, and the two click mechanisms do not interfere with each other. , the operator can clearly sense the predetermined position in the multi-contact switching.

Further, as shown in FIG. 4B, the surface on which the first click groove 23 is formed and the surface on which the second click groove 24 is formed are arranged so as to be offset in the thickness direction of the click plate 14 with a step. Therefore, even if the relative positional relationship between the leaf spring 13 and the click plate 14 is slightly shifted during assembly, the two click mechanisms will not interfere.
