Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a slider for an electronic component such as a sliding type variable resistor.

[Conventional technology]

BACKGROUND OF THE INVENTION Electrical devices often use electronic components that include sliders, such as sliding variable resistors.

FIGS. 6 to 8 are diagrams showing conventional examples of such slide type variable resistors.

FIG. 6 is an exploded perspective view of a slider S that slides inside the case of the slide type variable resistor to change its resistance value. In the figure, reference numeral 5 denotes a sliding element body integrally molded from synthetic resin;
is equipped with a lever 51 for sliding the slider S on the upper part of the sliding base 53, legs 55 provided at the four corners of the sliding base 53, and protrusions 57 and 59 provided on the lower surface of the sliding base 53. do. Reference numeral 6 denotes a click spring made of elastic metal that is placed on the sliding base 53 of the sliding element body 5, and the click spring 6 has a hole 61 having a shape and size through which the lever 51 passes through the click spring 6. There is a sliding element body 5 on both sides.
and a click spring section 65 for producing a click sensation when sliding the sliding element main body 5.
is formed. The upper part of the click spring part 65 engages with a recess 105 of the case 10 described below.
A detachable click protrusion 67 is formed. 7
is a slide plate made of synthetic resin that is placed on the click spring 6; approximately in the center of the slide plate 7 there is a hole 71 shaped and dimensioned to allow the lever 51 to pass therethrough, and a hole 71 shaped to allow the click spring portion 65 of the click spring 6 to pass therethrough. A hole 73 of the same size is formed. The length of the hole 73 in the vertical direction is limited so that the end 65a of the click spring portion 65 cannot pass through it. 8 and 9 are sliding terminals each made of an elastic metal, and each of the sliding terminals 8 and 9 is formed with terminal portions 81 and 91 that come into sliding contact with the sliding resistance pattern described below, and also has terminal portions 81 and 91 that are in sliding contact with the slide resistance pattern described below. Protrusion 5
Holes 83 with shapes and dimensions that engage with holes 7 and 59, respectively;
93 is formed.

To assemble the slider S, first insert the lever 51 into the hole 61 of the click spring 6 to place the click spring 6 on the sliding base 53. Next, the slide plate 7 is placed on the sliding base 53 by inserting the lever 51 into the hole 71 of the slide plate 7 and causing the click protrusion 67 of the click spring part 65 to protrude from the hole 73. On the other hand, by inserting the protrusions 57 and 59 on the lower surface of the sliding base 53 of the sliding element main body 5 into the holes 83 and 93 of the sliding terminals 8 and 9, respectively, and hot caulking the tips of the protrusions 57 and 59, The sliding terminals 8 and 9 are fixed to the sliding base 53 of the sliding element main body 5. This completes the assembly of the slider S.

FIG. 7 is an assembly diagram of a slide type variable resistor using the slider S described above. Reference numeral 10 denotes a case of a sliding type variable resistor made of synthetic resin. A plurality of slide holes 101 are formed in the upper surface of the case 10, and a plurality of protrusions are formed on both sides of the case 10. Reference numeral 11 denotes a substrate on which a plurality of slide resistance patterns 111 are formed. The protrusion 103 of the case 10 is attached to the substrate 11.
A hole 113 is provided at a position corresponding to.

To assemble the slide type variable resistor, the lever 51 of the slider S is inserted into the slide hole 101, and the hole 113 of the substrate 11 is inserted into the protrusion 103, and then the tip of the protrusion 103 is heat caulked. By doing so, the case 10 is fixed onto the substrate 11. At this time, the terminal portions 81 of the sliding terminals 8 and 9 of the slider S,
91 comes into contact with the slide resistor 111.

FIG. 8 is a sectional view of essential parts showing the relationship between the slider S, the case 10, and the substrate 11. Sliding terminals 8, 9
slides on the slide resistance pattern 111 by moving the lever 51 in the direction of the arrow shown in the figure. When the click protrusion 67 of the click spring section 65 engages with the recess 105, the slider S produces a click sensation. In addition, the resilient spring portion 63 of the click spring 6 connects the slide plate 7 to the case 1.
Since the slider S bounces in the 0 direction, an appropriate sliding force is maintained for the movement of the slider S. Furthermore, since the slide plate 7 is made of synthetic resin, its sliding motion is smooth.

[Problem that the invention attempts to solve]

However, the conventional slide type variable resistor as described above has the disadvantage that it has a large number of parts, requires time to assemble, and is also expensive. In addition, since the slider S, click spring 6, and slide plate 7 are arranged overlappingly between the case 10 and the board 11, the total dimensional error of each component becomes large, which not only causes variations in the performance of the finished product. However, the distance d between the case 10 and the substrate 11 becomes large, and the slide type variable resistor cannot be miniaturized.

The present invention has been made in view of the above points, and the object is to provide a slider for use in electronic components such as sliding type variable resistors that eliminates the above drawbacks, has a small number of parts, and is easy to assemble. .

[Means for solving problems]

In order to solve the above problems, the present invention comprises a sliding base, a lever integrally formed on the sliding base, and two sliding terminals fixed to the lower surface of the sliding base.
A slider for an electronic component in which a lever protrudes from a slide hole provided at the top of an electronic component case, and a sliding terminal slides on a board by moving the lever along the slide hole. The sliding base is integrally formed with a spring part that holds the lever and protrudes from the upper surface of the sliding base on both sides, and a click part that has a click convex part at the tip, and one of the two sliding terminals has a corresponding one. A resilient spring portion is formed that is bent upward from the surface of the sliding terminal, and a click spring portion is formed on the other side that is bent upward from the surface of the sliding terminal, so that the two sliding terminals can be slid. A slider is constructed by fixing to the lower surface of the movable base so that the resilient part is pushed upward by a resilient spring part, and the click part is pushed upward by a click spring part.

[Effect]

With the above configuration, the two sliding terminals are fixed to the lower surface of the sliding base in such a way that the resilient spring part pushes up the resilient part and the click spring part pushes the click part upward. Therefore, unlike the conventional slider described above, the click spring and slide plate can be omitted, the number of parts is reduced, and the performance of the finished product is less likely to vary due to the total dimensional error of each part.
Furthermore, since the slider can be treated as a single component, it becomes easier to assemble electronic components such as a sliding variable resistor.

Furthermore, since the resilient portion 16 and the click portion 17 are made of synthetic resin, their sliding motion is smooth. In addition, if grease is applied on the resilient part 16 and the click part 17, the sliding thereof will be made even smoother. When the click convex portion 17a of the click portion 17 engages with the concave portion 105, the slider S
produces a clicking sensation.
