The present invention relates to a sliding electronic component suitable for use in a slide variable resistor or slide switch.

Background Art Conventionally, in electronic equipment such as sound equipment, slide electronic components such as slide variable resistors for adjustment and slide switches for switching have been frequently used.

10 is an exploded perspective view of such a conventional slide variable resistor. As shown, the slide variable resistor includes a case 100, a sliding body 110, and a substrate 120.

The case 100 is box-shaped, and the long holes 101 for projecting a plurality of operating levers are formed in the upper portion thereof. In the sliding body 110, the base portion 111 and the operation lever 112 are integrally formed, and the operation lever 112 is installed at an almost center portion of the upper portion of the base portion, and near the side of the operation lever 112. The click spring 113 is attached. The substrate 120 is provided with various patterns 121 such as resistor patterns and current collector patterns on the upper surface thereof. In addition, although not shown, the sliding contact which slides on the various patterns 121 of the board | substrate 120 is attached to the bottom part of the base part 111 of the sliding body 110. As shown in FIG.

The assembly of the slide type variable resistor having the above-mentioned component parts projects the operation lever 112 of the sliding body 110 upwardly from the long hole 101 of the case 100, and thus the protrusion formed on the lower part of the case 100. 102 is inserted into the hole 122 of the board | substrate 120, and the front-end | tip of the protrusion part 102 is tightened and it combines and the case 100 and the board | substrate 120 are performed.

11 is a side sectional view showing the main portion of the slide-type variable resistor. As shown, the base portion 111 of the sliding body 110 is positioned between the case 100 and the substrate 120, and the sliding contact 114 attached to the bottom of the base portion 111 is the substrate 120. It is arranged to slid to the various patterns 121 of). By operating the operation lever 112, the base portion 111 of the sliding body 110 moves between the case 100 and the substrate 120 to change the resistance value, while the click spring 113 is the case 100. It fits in the click hole 103 formed in the inside, and is detached | released, and it gives a click feeling.

Reference numeral 130 in FIG. 11 denotes a slide plate sandwiched between the base 111 and the case 100.

However, in the conventional slide type variable resistor as described above, it is necessary to attach the sliding contact 114 to the sliding body 110, or to attach the click spring 113, and the number of assembling steps increases. There is a problem in that the number of parts increases due to the need to independently form the click spring 113 or the sliding contact 114.

In addition, since the sliding body 110, the click spring 113, and the slide plate 130 are disposed so as to overlap between the case 100 and the substrate 120, the dimensional error of each part becomes large, and the performance of the finished product is uneven. Not only does this occur, but the case 100 and the board | substrate 120 become large, there also existed a problem that miniaturization of a slide type variable resistor was not possible.

In addition, there is a drawback that the sliding of the click spring 113 and the case 100 is not smooth, as a countermeasure, in the conventional slide type variable resistor, the click spring is formed of synthetic resin in order to facilitate the sliding movement of the sliding body 110. There is one, but the sliding movement of the sliding body 110 is smooth, but because the click spring is made of a resin, there was a problem that the so-called sticky occurs in the click spring at high temperatures.

In addition, the appearance of various patterns 121 formed in the case 100, particularly on the upper surface of the substrate 120, from the long hole 101 formed in the case 100 has caused a problem of impairing aesthetics.

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-described problems, and provides a slide-type electronic component which eliminates the above-mentioned problems, has a small number of parts, has a miniaturization thereof, is easy to assemble, and has excellent aesthetics.

In addition, since the click spring is integrally formed with the sliding body, the reinforcing plate is integrally formed with the sliding contact, and the sliding contact and the reinforcing plate are insert-molded on the sliding body, and both are integrally integrated. In addition, the assembly is easy and the movement between the parts can be completely eliminated.

In addition, since various patterns on the substrate to which the sliding contact slides are not located directly under the operation lever position of the base portion of the sliding body, the pattern inside the case, in particular, the upper surface of the substrate is not seen from the long hole of the case, so that the pattern is excellent. It becomes.

In addition, when the spacer is sandwiched between the portion of the base of the sliding member and the portion between the substrate and the substrate, the surface of the substrate itself is also invisible.

)(13)이 형성되어 있다. 그리고 케이스(10)는 금속판으로 형성되어 있다.As shown in FIG. 1, the case 10 has a plurality of elongated holes 11 through which the operation lever 22 of the sliding body 20 penetrates at a predetermined position. On one side, a click hole 12 is formed in which the protrusion 24a of the click spring 24 fits in and leaves. Here, the width of the long hole 11 is formed to be slightly wider than the width of the operating lever 22 of the sliding body 20, and the entire surface of the case 10 except for the long hole 11 is formed of the substrate 40 to be described later. Various patterns 41 and the like are formed so that they are not visible. In addition, a tongue-shaped operation for fixing the case 10 to the substrate 40 at a predetermined lower peripheral position of the case 140 (

(13) is formed. The case 10 is formed of a metal plate.

As shown in FIG. 1, the substrate 40 has various patterns 41,... Which consist of a resistor pattern, a current collector pattern, or the like, in which the contacts 23a of the contact members 23,... Of the sliding body 20 slide. Is formed. Moreover, the board | substrate 40 is provided with the hole 42 and the recessed part 43 in which the piece 13 of the case 10 for attaching the case 10 is fitted.

The spacer 30 is divided into three compartments 31a, 31b, 31c, as shown in FIGS. 1 and 6 (FIG. 6 is a plan view of the space 30), and the compartments 31a, 31b, One sliding body 20 is arrange | positioned at 31c), respectively, and this sliding body 20 is guided in a predetermined direction. On both sides of each of the partitions 31a, 31b and 31c, support portions 32 and 33 are formed to support both bottoms of the base portion 21 of the sliding body 20 by sliding.

One of the support parts 32 and 33 is formed to be wider than the support part 33.

Next, the assembly of the slide type variable resistor made of the above-mentioned member will be described.

First, the sliding body 20 is formed by the thickness portions 21a and 21b of the base portion 21 to the respective support portions 32 and 33 (see FIG. 6) of the partitions 31a, 31b and 31c of the space 30, respectively. So that it is positioned. Next, the spacer 30 on which the sliding body 20 is placed is placed on the substrate 40, and the case 10 is fixed to the substrate 40. The substrate 40 and the case 10 are fixed by inserting the pieces 13 into the holes 42 and the recesses 43 into which the pieces 13 are fitted, and bending the ends of the pieces 13. As a result, the operation lever 22 of the sliding body 20 protrudes upward from the long hole 11 of the case 10.

The contacts 23a of the contact members 23,... Exposed to the bottom of the base portion 21 abut on the various patterns 41 on the substrate 40. The state which saw this assembled slide type variable resistor from the top is shown in FIG.

Next, the operation of this slide type variable resistor will be described with reference to FIG. 7 and FIG. 8 is a cross-sectional view taken along the line D-D of FIG.

As shown in FIG. 8, both sides of the base portion 21 of the sliding body 20 are supported on both supporting portions 32 and 33 of the spacer 30, and the operating lever 22 of the sliding body 20 is supported. Protrudes upward from the long hole 11 of the case 10. Therefore, when the operation lever 22 is moved along the long hole 11, each of the contacts 23a of the contact members 23, ... slides over the various patterns 41 of the substrate 40. Therefore, the resistance value between each terminal part (not shown) pulled out from these various patterns 41 changes.

At this time, since the click spring 24 of the sliding body 20 is bent upward by the reinforcing plate 25, the protrusion 24a of the click spring 24 moves while flipping the inner surface of the case 10. . Therefore, when this protrusion part 24a is fitted in the click hole 12 formed in the case 10, a click feeling arises from this sliding body 20. FIG.

Here, since the projection part 24a of the click spring 24 is formed of synthetic resin, the movement in the case 10 is smooth, and the projection part 24a of the click spring 24 and the click of the case 10 are carried out here. The fitting of the hole 12 is also smooth.

In particular, when the lower surface of the click hole 12 of the case 10 as shown in FIG. 5 is rounded, the click sensation becomes smooth.

In addition, since the reinforcing plate 25 is integrally formed with the sliding contact substrate 26 forming the contact member 23, only the reinforcing plate 25 is fixed to the base 21 made of synthetic resin alone. In comparison, the elastic force is large.

In addition, either of the contact member 23 and the reinforcing plate 25 is electrically conductive through the sliding contact substrate 26. Even if the case 10 is made of metal, the upper surface of the reinforcing plate 25 is made of synthetic resin. Since the click spring 24 is formed, the contact 23a of the contact member 23 and the case 10 do not become electrically conductive.

Moreover, since the reinforcement board 25 was inserted in the said click spring 24, and both were integrated, the elastic strength does not become small even at high temperature compared with the case of only the click spring which consists of synthetic resins.

In the slide type variable resistor according to the present embodiment, as shown in FIG. 8, the contacts 23a, ... of the contact members 23, ... attached to the base portion 21 of the sliding body 20 are the base portions. Since it is attached to the position biased to one side from the lower part of the position which attached the operation lever 22 of 21, correspondingly, the various types on the board | substrate 40 with which the contact 23a, ... slides correspondingly are corresponded. The pattern 41 also does not come directly under the part to which the operation lever 22 is attached. Therefore, since the various patterns 41 of the inside of the case 10, especially the surface of the board | substrate 40 are not seen from the long hole 11 formed in the case 10, it becomes a slide type variable resistor excellent in aesthetics.

In addition, in the slide-type variable resistor according to the present embodiment, a spacer (between the bottom portion of the position where the operation lever 22 of the base portion 21 of the sliding body 20 is attached and the substrate 40 is provided. When the support part 32 of the 30 is inserted to cover the surface of the substrate 10 seen from the long hole 11 of the case 10, the surface of the substrate 40 is also invisible, and the various patterns 41 as described above. Not only can it be seen from the outside, it also improves the beauty.

(4) The position of the contact members 23,... Attached to the base portion 21 of the sliding body 20 is not limited to the position of the above embodiment. For example, FIG. 9 is a cross-sectional view of main parts of the slide-type variable resistor of another embodiment of the present invention, and as shown, the contact members 23,... Of the slipper 20 are immediately below the position of the operating lever 22. It can also be provided in both sides, and even if comprised in this way, the various patterns 41 formed in the upper surface of the board | substrate 40 from the elongate hole 11 of the case 10 are not seen from the exterior. In addition, as shown, the spacer 30 forms the plate-like member 34 for the predetermined hole cover at a position corresponding to the lower portion of the operating lever 22, thereby removing the substrate (from the long hole 11). The surface of 40) becomes invisible, resulting in good aesthetics. In other words, the insert position of the contact members 23,... To the base portion 21 may be a portion other than the portion immediately below the operation lever 22.

In the above embodiment, an example of the slide type variable resistor has been shown, but the present invention is not limited to the slide type variable resistor, provided that the sliding contact formed at the bottom of the base portion of the sliding body slides the pattern on the substrate.
