Description

  The present invention relates to an automatic return electronic component that automatically returns to a predetermined return position from a position where a moving body such as an operation knob has moved, and an assembling method thereof.

  Conventionally, in an electronic component, for example, a slide-type electronic component, an electric output (for example, a switch on / off state or a resistance value) is changed by moving the operation knob, and the movement of the operation knob is canceled. There is an automatic return type electronic component having a structure in which the operation knob automatically returns to a predetermined return position (for example, neutral position) and stops.

  For example, as shown in FIG. 2 of Patent Document 1, this type of automatic return type electronic component is provided in a coil spring housing portion (54) provided in a sliding type object (50) to which a slider (60) is attached. The coil spring (55) is compressed and accommodated, and then the lower case (40) is put on the sliding type object (50), and the flexible circuit board (70) is placed on the lower surface of the lower case (40). ) And the mounting member (80). Both ends of the coil spring (55) housed in the coil spring housing part (54) are connected to the latching parts (56c, 56d) of the coil spring housing part (54) and the contact part provided in the lower case (40). (49c, 49d). When the sliding object (50) is slid, the slider (60) slides on the switch pattern (71) on the flexible circuit board (70), and its on / off output changes. At this time, the coil spring (55) is compressed by being pressed by the other locking portion (56d or 56c) while the other end is in contact with the one contact portion (49c or 49d). The resilient force that automatically returns the sliding object (50) to the neutral position is urged. Accordingly, when the movement of the sliding object (50) is released, the sliding object (50) automatically moves to the original neutral position and stops.

However, in the conventional automatic return type electronic component, as described above, the coil spring (55) is accommodated in the coil spring accommodating portion (54) provided in the slide type object (50), and then this sliding type is used. When mounting the object (50) so that the lower case (40) is covered, the abutting part (49c or 49d) of the lower case (40) comes into contact with the end of the coil spring (55), and compression is performed. In some cases, the coil spring (55) is popped out of the coil spring housing part (54), or the end of the coil spring (55) is damaged or deformed, resulting in poor assembly. In order to prevent this phenomenon, when the sliding type object (50) containing the coil spring (55) is assembled into the lower case (40), the coil spring (55) is slightly affixed with a special jig separately prepared at both ends. There is also a method in which the sliding type object (50) is incorporated in the lower case (40) in a compressed state. However, in this method, not only a special jig is required, but also the work of assembling the sliding object (50) into the lower case (40) becomes complicated.

As shown in these drawings, the automatic return type electronic component 1-2 also includes a case 10 that is a fixed member, a moving body 40 that is housed in the case 10, and an electrical functional unit that is attached to the moving body 40. These are a slider 70, a resilient member (hereinafter referred to as “coil spring”) 90 accommodated in a resilient member accommodating portion 49 provided on the moving body 40, and a fixed-side member installed on the lower surface side of the case 10. The circuit board (hereinafter, referred to as “flexible circuit board”) 100 and a mounting plate 130 that is a fixed member installed on the lower surface side of the flexible circuit board 100 are provided.

  In this embodiment, the only difference from the previous embodiment is the shape of the case 10 and the moving body 40. That is, the case 10 according to this embodiment is different from the case 10 according to the first embodiment in that the side surface of the portion between the two locking portions 17 on the side surface provided with the pair of locking portions 17 is notched. The only difference is that the height dimension from the upper surface is shortened, and the space in the lower part is used as the first elastic member insertion port 19.

  Further, the moving body 40 according to this embodiment differs from the moving body 40 according to the first embodiment in that the elastic member insertion port 47 provided on the lower surface of the moving body 40 provided in the first embodiment is eliminated, and instead. The second elastic member insertion port 47-2 is only provided on one side surface (the side surface facing the locking portion 17 of the case 10) parallel to the slide movement direction A of the movable body 40 ( Note that the elastic member insertion port 47 on the lower surface of the moving body 40 may be provided as it is).
