Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a variable resistor, and more particularly to a variable resistor whose resistance value can be easily adjusted.

0002

[Conventional technology]

A variable resistor mounted on a conventional printed circuit board has only one adjustment surface for adjusting the resistance value. I only had one place. In other words, a variable resistor with an adjustment surface horizontal to the printed board. and a variable resistor with an adjustment surface perpendicular to the printed circuit board. and, When installing a variable resistor on a printed circuit board, consider the arrangement of components around the variable resistor. The two types mentioned above were used separately.

0003

[Problem that the idea aims to solve]

With this conventional variable resistor, the adjustment process of the variable resistor is required after it is incorporated into the device. There are two or more resistance adjustment steps, one from the top of the printed board and one from the side. In cases where there are two types of cases, the disadvantage is that it is difficult to adjust one of them. there were.

0004

[Means to solve the problem]

The variable resistor with two-way adjustment surface according to the present invention has a resistance value variable mechanism of the variable resistor body. a first adjustment surface connection gear that rotationally drives the first adjustment surface connection gear, and a first adjustment surface connection gear that rotationally drives the The shaft is arranged in a vertical direction, and the gear for connecting the first adjustment surface is rotationally driven by a gear. and a second adjustment surface connection gear.

【Example】

Next, the present invention will be explained with reference to the drawings.

[0006] FIG. 1 is a sectional view of an embodiment of the present invention.

[0007] This variable resistor with two adjustment surfaces drives the resistance value variable mechanism of the variable resistor main body 3. It has a gear 2 for connecting the adjustment surface. The adjustment surface connection gear 2 is located on the top surface of the case 7. It is connected to the provided horizontal adjustment section 1, and is rotated by the rotation of the horizontal adjustment section 1. Ru. The tip a of the adjustment surface connection gear 2 is connected to the resistance variable mechanism of the variable resistor body 3. has been done. The variable resistor main body 3 is used as a resistance value variable mechanism, for example, if a part is missing. Pressure is applied to two places: a circular resistor, a contact point provided at the center of the circle, and the resistor. It has a brush for better connection. Then, by rotating the brush, Effectiveness of the resistor connected to the printed board connection terminals 6a and 6b via contacts, etc. By changing the length, the resistance value of the variable resistor is changed.

[0008] The adjustment surface connection gear 2 further includes an adjustment surface connection whose shaft is installed perpendicularly to the adjustment surface connection gear 2. It is connected to the gear 5 by a gear. The adjustment surface connection gear 5 is on the side of the case 7. It is connected to the vertical plane adjusting parts 4a, 4b provided on the plane, and the vertical plane adjusting parts 4a, 4 The adjustment surface connection gear 2 is rotated by the rotational force from b. Therefore, for connecting the adjustment surface Gear 5 drives the resistance value variable mechanism of the variable resistor main body 3 via the adjustment surface connection gear 2 can.

[0009] With such a drive mechanism that drives the resistance value variable mechanism of the variable resistor main body 3, This variable resistor has a horizontal surface adjustment section 1 and a vertical surface adjustment section 4. The resistance value can be easily adjusted from two directions of the vertical plane where a and 4b are provided. say In other words, the two horizontal plane adjustment parts 1 and the vertical plane adjustment parts 4a and 4b, which are perpendicular to each other, The resistance value can be adjusted from the direction.

0010

[Effect of the idea]

As explained above, the present invention has two resistance adjustment surfaces perpendicular to each other. The resistance value can be adjusted from any direction, especially when built into equipment. This has the effect of being easy to adjust.
