Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a slide operation type electric component, and more particularly to a slide operation type electric component having a height as small as possible.

[0002]

[Prior Art]

 As shown in FIG. 5, a slide operation type variable resistor, which is an example of a conventional slide operation type electric component, has a resistor (not shown) formed on the upper surface, and an insulating substrate 2 having terminals 1 at both ends is formed on the center of the upper surface. A long groove 3 is bored in the case, and a side face is covered with a case 5 having mounting feet 4. Between this insulating substrate 2 and case 5, a slider (not shown) that slides on the resistor of the insulating substrate 2 is provided. The lever 7 provided on the slider holder 6 is projected from the long groove 3 of the case 5 to the upper surface of the case 5 with the fixed slider holder 6 interposed.

By the way, in the above-mentioned slide operation type variable resistor, since the lever 7 is projected upward from the upper surface of the case 5, the height dimension Ho is correspondingly increased, so that it is mounted on a panel or a printed circuit board. In this case, high integration cannot be achieved due to space and design.

Therefore, a device for making the height dimension smaller than Ho in FIG. 5 is disclosed in Japanese Utility Model Application Laid-Open No. 58-144805.

6 to 9 are drawings described in this publication, FIG. 6 is a perspective view seen from an operation surface of a slide operation type variable resistor, and FIG. 7 is a perspective view seen from the back surface thereof. FIG. 8 is a perspective view showing an assembled state of the slider receiver and the lever, and FIG. 9 is a sectional view showing a swaged state of the slider receiver and the lever.

6 to 9 described above, the side plate 5a of the case 5 is provided with a long groove 3a from which the lever 7 projects, and the slider receiver 6 is operated from the side plate 5a side of the case 5. As a result, the height dimension H ₃ of the slide operation type variable resistor is made smaller than the conventional height dimension Ho.

[Problems to be solved by the device]

 By the way, the slide operation type variable resistor described in Japanese Utility Model Laid-Open No. 58-144805 has a case 5 in which a long groove 3a is provided in a side plate 5a in a state where a slider 7 is integrally provided with a lever 7. In this case, the lever 7 interferes with the storage and it is difficult to store it. Therefore, there is a problem in assembling work. Therefore, as shown in FIG. 6 is housed in the case 5, the insulating substrate 2 is caulked to the case 5, and then the mounting portion 7a of the lever 7 is inserted into the hole 6b of the slider receiver 6, and then the back side surface 5b of the case 5 is inserted. The tool is inserted from the provided caulking hole 8 and the caulking portion 7b is formed in the caulking groove 6d to fix the lever 7 to the slider receiver 6, but in this case, the number of parts increases and the structure becomes complicated. However, there is a problem that the work process increases and the cost increases. .

The present invention is intended to solve the above problems, and an object of the present invention is to reduce the height dimension of a slide operation type electric component as much as possible and to simplify the structure. It is intended to provide a slide operation type electric component having good assembling workability.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides an insulating substrate having a pattern formed on one surface, a slider receiver having a slider in sliding contact with the pattern, and a housing for the slider receiver. In a slide operation type electric component having a case, a side wall of the case is provided with a notch having an open lower end, and the slider receiving member is provided by a long groove defined between the notch and the insulating substrate. I made the knob of the projecting.

[0010]

[Action]

 According to the present invention, the side plate of the case is provided with a notch having an open lower end, and a long groove is defined between the notch and the insulating substrate. Since the pendulum receiver is operated from the side plate of the case, the height dimension of the slide operation type electric component can be made as small as possible, and the side plate of the case has a notch with an open lower end. By providing the slider holder, the slider holder can be easily housed in the case even when the knob is provided integrally with the slider holder, which improves the assembling workability as compared with the conventional one. By integrating the lever with the moving element receiver, the number of parts can be reduced and the step of crimping the sliding element receiver and the lever can be omitted, so that the cost can be reduced.
