Description

  The present invention relates to a sliding electronic component such as a sliding switch.

  Conventionally, as a sliding electronic component, there is a sliding electronic component (sliding variable resistor) described in Patent Document 1. In this sliding electronic component, a sliding type object is slidably accommodated in a case, and a slider attached to the lower surface of the sliding type object is provided on a substrate installed below the sliding type object. By sliding on the resistor pattern, the resistance value between the resistor patterns changes. By the way, the slide-type electronic component described in Patent Document 1 is formed by integrally forming a slide-type object and an operation knob for operating the slide-type object with the same member. This is a structure in which a protruding portion that is an operation knob is protruded.

  However, the material of the sliding-type material is sufficient for heat-caulking materials and repeated deformation because the slider is attached by heat caulking, or a resilient contact arm for the click mechanism is provided. It will be limited to the material which can maintain elasticity. For this reason, the material of the portion of the operation knob integrated with the sliding type object is also limited to the above material, but this material is not necessarily a preferable material for decoration. I couldn't decorate.

  On the other hand, in the case of a slide-type electronic component having a slide-type object integrated with the operation knob, when the slide-type object is stored in the case at the time of assembly, the operation knob portion projects upward from the hole on the upper surface of the case. Therefore, the operation knob cannot be made larger than the hole of the case, so that the hole of the case and the surrounding area cannot be hidden by the operation knob, and the appearance of the operation knob is deteriorated. There was also.

  In order to solve the above-described problems, the sliding object 120 and the operation knob 130 may be separated as in the sliding electronic component 100 shown in FIG. That is, the slide type electronic component 100 houses a sliding object 120 slidably in a case 110, and further has a flexible substrate 140 and a mounting plate 150 installed on the lower side of the case 110 and an upper side of the case 110. An operation knob 130 is installed, and the operation knob 130 and the sliding mold 120 are integrally fixed. Here, the sliding mold 120 and the operation knob 130 are fixed to each other with the protrusion 121 protruding from the upper surface of the sliding mold 120 through the opening 111 provided on the upper surface of the case 110. This is done by inserting it into an engaging portion 131 made of a hole provided on the lower surface. Reference numeral 125 denotes a slider attached to the lower surface of the slide-type object 120, which slides on the switch pattern 141 provided on the flexible substrate 140. In addition, the sliding electronic component 100 is provided with a click mechanism 160 that generates a click sensation when the sliding object 120 slides. The click mechanism portion 160 is provided with a click spring portion 112 formed by cutting out a part of a metal plate constituting the case 110 on the upper surface of the case 110, and a concave click mechanism provided on the upper surface of the sliding object 120. The click spring 112 is engaged with the joint 122.

  If the slide-type object 120 and the operation knob 130 are separate parts as in the slide-type electronic component 100, the material of the operation knob 130 is not limited to the material of the slide-type object 120, and is suitable for decoration. Can be selected freely, so that the desired decoration can be applied to the operation knob 130. Further, since the opening 111 of the case 110 and its peripheral portion can be covered by the operation knob 130, even when the operation knob 130 is installed so as to be directly exposed on the surface of the exterior case, the appearance is improved.

  However, in this sliding electronic component 100, the fixing structure between the sliding mold 120 and the operation knob 130 is a structure in which the protrusion 121 of the sliding mold 120 is inserted into the engaging portion 131 of the operation knob 130. In addition, since the both are not firmly fixed unless the insertion depth of the protrusion 121 into the engaging portion 131 is increased to some extent, the height of the operation knob 130 is increased accordingly, and the entire slide electronic component 100 is increased. There has been a problem that the height dimension cannot be reduced.

  Even if the engagement length between the engaging portion 131 and the protruding portion 121 is increased, the protruding portion 121 of the sliding mold 120 is only inserted into the engaging portion 131 of the operating knob 130. If the 130 is pulled upward with a strong force, the operation knob 130 may be detached from the sliding object 120. In order to prevent this fear, a snap-in engagement structure may be used between the protrusion 121 and the engagement portion 131. However, if it does so, both engagement structure will become more complicated and the height dimension of the operation knob 130 will become high.

Further, as described above, the sliding electronic component 100 is provided with the click mechanism 160, but since the protrusion 121 is provided on the upper surface of the sliding object 120, the click mechanism 160 is provided with the protrusion. It must be installed at a position around it, avoiding 121. Then, since the protrusion 121 and the click mechanism 160 are provided side by side on the upper surface of the sliding mold 120, the width dimension of the sliding electronic component 100 (perpendicular to the sliding direction of the sliding mold 120). In the horizontal direction), and the width of the sliding electronic component 100 cannot be reduced.
