JP 11-353976 A Japanese Patent Application Laid-Open No. 2004-1778989

  In the case of the pressing and rotating electronic component with illumination function according to Patent Document 1, since the light emitting element is installed at a position facing the lower end surface of the transparent shaft, the shaft can be efficiently illuminated. Instead, it is necessary to install the push switch at a position away from the rotation axis of the shaft. For this reason, downsizing of the outer diameter of the electronic component is hindered, and when there is one press switch (in the case of Patent Document 1, two press switches are balanced), the shaft is pressed to turn on the press switch. In doing so, a force in a direction in which the shaft is tilted is applied, and the operation feeling may not be good.

  In order to solve the above problem, as shown in Patent Document 2, it is only necessary to install a push switch directly under the shaft. However, in this case, on the contrary, the light emitting element cannot be installed directly under the shaft, and thus there is a problem that efficient illumination of the shaft is hindered.

  The present invention has been made in view of the above points, and an object of the present invention is to provide an electronic component with an illumination function that can perform effective illumination and can smoothly perform a pressing operation of the pressing electronic component. There is to do.

An electronic component with an illumination function according to the present invention is an electronic component with an illumination function including a light emitting element. The electronic component with a light emitting element includes a flexible circuit board, and the light emitting element installation circuit board is provided on the flexible circuit board. A case that houses the light emitting element installation circuit board, and a terminal that is attached to the case with one end protruding to the outside of the case and the other end exposed on the bottom surface of the case, and A terminal connection pattern is formed on a part of the circuit board for installing the light emitting element that is drawn from the part where the light emitting element is installed, and the terminal connection pattern and the exposed surface of the terminal exposed on the bottom surface of the case are arranged on the light emitting element installation. It is characterized by being connected and conducted by being pressed by an elastic member installed on the circuit board .
Since the terminal connection pattern of the circuit board for installing the light emitting element is directly connected to the exposed surface of the terminal and conducted, the light emitting element and the terminal can be reliably conducted with a simple structure.

Further, the present invention provides the electronic component with a lighting function, wherein a press switch is installed on a bottom surface in the case, and an operating body for operating the press switch is housed in the case so as to be movable up and down. The part of the circuit board for installation where the light emitting element is installed is mounted on the operating body.
Thereby, a press switch and an operation body can be stored compactly in a case.

According to another aspect of the present invention, there is provided an electronic component with an illumination function, wherein the light guide member has translucency and has an element storage portion that stores the light emitting element on a lower surface side, and is disposed above and below the light guide member. A light-emitting element mounted on the operating body in a state of being housed in an element housing portion of the light guide member, and the shaft is interposed via the light guide member. The operating body is operated.
By providing the light guide member, the light emitted from the light emitting element can be reliably guided to the shaft side. Further, since the light emitting element is accommodated in the element accommodating portion provided in the light guide member, the light emitting element is not destroyed by the pressing of the pressing switch by the shaft, and at the same time, the size in the height direction can be reduced.
In addition, the light guide member, the light emitting element, and the operating body can be integrated (unitized), and the electronic component with illumination function can be assembled more easily.
In addition, since the pressing switch is installed below the shaft via the operating body, the pressing operation of the pressing electronic component by pressing the shaft can be performed smoothly. Furthermore, since the light emitting element is installed just under the shaft on the operating body, the shaft can be effectively illuminated by the light emitting element. Further, since the light emitting element and the push switch are arranged above and below, even if the light emitting element is installed, the installation space of the push switch is not limited by the light emitting element. Therefore, even if a reversing plate is used for the pressing switch, a reversing plate having the same size as the conventional one can be easily used. For this reason, it is possible to easily change the pressing operation stroke and pressing force of the shaft.

  According to the present invention, it is possible to perform effective illumination, and it is possible to smoothly perform the pressing operation of the pressing electronic component.

At this time, the locking portion 197 of the operating body 190 is inserted into the locked portions 175 and 155 of the first case 150 to position the operating body 190 in the operating body storage portion 153. That is, the operating body 190 does not rattle in the first case 150. Then, both ends of the cover member 220 are inserted into the pair of cover member insertion portions 159 of the first case 150 to close the notch portions 157. As a result, as shown in FIGS. 2 and 3, the pressing portion 203 of the operating body 190 is disposed at the center of the reversing plate 171 a of the pressing switch 171, and the light emitting element 173 is disposed thereon.

  Next, the click spring 30 is disposed on the lower surface of the upper surface portion 11 of the cover 10, and each locking piece 33 of the click spring 30 is engaged with each engagement portion 19 of the cover 10, whereby the click spring 30 is attached to the cover 10. Lock. Next, the shaft 50 is inserted into the shaft support portion 15 from the lower surface side of the cover 10. Next, the rotating body 70 attached with the slider 90 is disposed below the shaft 50. At this time, the pressing base portion 55 of the shaft 50 is inserted into the insertion portion 71 of the rotating body 70. The pair of guide portions 57 of the shaft 50 are inserted into the guide portion insertion portion 73. At this time, both elastic contact portions 37 of the click spring 30 elastically contact the click elastic contact portion 75 of the rotating body 70.

To position. Further, at this time, the attachment portion 31 of the click spring 30 is accommodated in the recess 119 of the second case 110.

  Next, the first case 150 in which the operating body 190 and the like are accommodated is arranged below the second case 110, and then the distal end portions of the respective locking portions 23 of the cover 10 located on both outer sides of the first case 150 are arranged. The second case 110 and the first case 150 are integrated with the cover 10 by folding the first case 150 to the bottom surface side. Thereby, the electronic component 1 is completed. At this time, as shown in FIG. 2, the pressing portion 62 of the shaft 50 is in contact with the upper surface of the light emitting element installation portion 169 of the first flexible circuit board 161, and the light emitting element 173 is located in the element housing portion 61 of the shaft 50. Yes. The above assembling procedure is an example, and it goes without saying that the assembly may be performed using other various assembling procedures.

  When the shaft 50 is rotated, the rotating body 70 and the slider 90 rotate together with the shaft 50, and the contact portion 95 of the slider 90 slides on the sliding contact pattern 127 so that the terminals 131 are turned on and off. The output changes.

  On the other hand, when the shaft 50 is pressed in the direction of the rotation axis (downward), only the shaft 50 is lowered with respect to the rotating body 70, and the pressing portion 62 presses the operating body main body 195 from above the light emitting element installation portion 169. Then, the pressing portion 203 presses the reverse plate 171a of the pressing switch 171 to reverse it, and the pressing switch 171 is turned on. When the pressure on the shaft 50 is released, the reversing plate 171a is automatically restored to its original shape by the elastic restoring force of the reversing plate 171a. At the same time, the pressing switch 170 is turned off, and the shaft 50 returns to the original raised position.

  When the light emitting element 173 emits light, the light is introduced into the transparent shaft 50 covering the top and the periphery of the light emitting element 173, and is emitted toward the top of the shaft 50 to illuminate the top of the shaft 50 brightly.

  In the electronic component 1, as described above, since the rotating body 70 is rotated by the shaft 50 that passes through the rotating body 70 so as to freely move up and down, the rotating operation of the rotary electronic component by the shaft 50 can be performed smoothly. . At the same time, since the pressing switch 171 is installed below the shaft 50 (directly in this example) via the operating body 190, the pressing operation of the pressing electronic component by pressing the shaft 50 can be performed smoothly. Further, since the light emitting element 173 is installed directly below the shaft 50 on the operating body 190, the light emitting element 173 can effectively illuminate the shaft 50. Since the light emitting element 173 is accommodated in the element accommodating portion 61 provided at the lower end of the shaft 50, the light emitting element 173 is not destroyed by the pressing of the pressing switch 171 by the shaft 50, and the size in the height direction can be reduced at the same time. Can be planned. Further, since the light emitting element 173 and the pressing switch 171 are arranged above and below, even if the light emitting element 173 is installed, the installation space of the pressing switch 171 is not reduced by the light emitting element 173. Therefore, even if the reversing plate 171a is used for the pressing switch 171, the reversing plate 171a can be easily used in the same size as the conventional one. For this reason, it is possible to easily change the pressing operation stroke and the pressing force of the shaft 50.

  In addition, the electronic component 1 includes a first case 150 having an operating body storage portion 153 that stores the operating body 190, and a pressing switch 171 is installed on the bottom surface of the operating body storage portion 153. The pressing switch 171 and the operating body 190 can be stored in a compact manner.

  The actuating body 190 is connected to the base 191 attached to the actuating body storage 153 of the first case 150, the flexible hinge 193 protruding from the base 191 and the tip of the hinge 193, and emits light on the upper surface. Since the element 173 is placed and the operating body main body 195 provided with the pressing portion 203 on the lower surface, the vertical movement of the operating body main body 195 provided with the pressing portion 203 is stable. The on / off operation of the pressing switch 171 by the shaft 50 can be performed more smoothly and reliably. Further, since the light emitting element 173 is mounted on the upper surface of the operating body main body 195, the light emitting element 173 can be stably held.

  In addition, the switch forming portion 167 of the first flexible circuit board 161 is installed on the inner bottom surface of the operating body storage portion 153 of the first case 150, and the light emitting element installation portion 169 is operated by folding the first flexible circuit board 161. Since the pressure switch 171 and the light emitting element 173 can be formed on one sheet of the first flexible circuit board 161 and the first flexible circuit board 161 is simply folded back, the push switch 171 and the light emitting element 173 can be formed on the upper and lower sides of the operating body 190.
