Description

  The present invention relates to an electric component holder that holds an electric component in a predetermined positional relationship with respect to a through hole formed in a plate-like body disposed on the front surface thereof.

  Conventionally, as an electrical component holder as described above, there is one disclosed in Patent Document 1, for example. The technology of Patent Document 1 is for arranging lenses on the front surface of each of a plurality of light emitting diodes arranged in a row. The long surface of a horizontally long box is arranged in a row along its length direction. The mounting surface has an opening on the opposite side to the lens surface, and a printed circuit board is attached to the mounting surface. A plurality of light emitting diodes are arranged on the printed circuit board so as to correspond to each lens. Is attached. A positioning plate is arranged on the inner surface of the box so as to face the lens surface at a predetermined distance from the lens surface, and positioning holes are formed in a row corresponding to each lens on the positioning plate. Each light emitting diode is inserted into the hole with its tip protruding from the positioning hole to the lens side.

  In the technique of Patent Document 1, when a printed circuit board on which a plurality of light emitting diodes are attached is attached to the opening surface of the box, each light emitting diode is inserted into a corresponding positioning hole, and the optical axis and lens of each light emitting diode are inserted. The deviation from the optical axis is corrected.

Japanese Utility Model Publication No. 2-46306

  According to the technique of Patent Document 1, a plurality of light emitting diodes arranged in a row can be arranged with their optical axes aligned with each lens and attached to the box. For example, a light emitting diode may be attached to the inner surface side of a plate-like body such as a panel of an electric device so that it can be observed from the outside of the panel. In this case, if it is going to utilize the technique of patent document 1, a panel must be formed in the box shape which has an opening in the inner surface side, and the positioning plate must be formed integrally with the box shape in the box shape, Manufacturing is cumbersome. In particular, in a plate-like body such as a panel, when the light emitting diodes can be observed from the outer surface, the light emitting diodes are not necessarily arranged in a row, and may be arranged at different positions on the panel. . In such a case, if the technique of Patent Document 1 is to be applied, a box shape having a positioning plate inside must be provided at a plurality of locations on the inner surface side of the panel. Application is impossible. For example, the technique of Patent Document 1 is provided with an electric component mounting surface on which a part of an electric component such as a plurality of switches protrudes instead of a box-shaped lens surface, and the electric component is operated from the outside of the box type. If possible, it can be applied to positioning of electrical parts by providing a positioning plate in the box. However, if this applied technology is also applied to a plate-like body such as a panel, Such a problem arises.

  An object of the present invention is to provide an electric component holder that can be positioned with a simple structure and can be arranged on a plate-like body so that it can be observed from the outside or operated from the outside.

  The electric component holder of one embodiment of the present invention has a plate-like body. The plate-like body has a first surface and a second surface opposite to the first surface, and a through-hole penetrating the first surface and the second surface is formed. The position restricting plate has a third surface arranged to face the second surface and a fourth surface opposite to the third surface. A restriction through-hole penetrating the third surface and the fourth surface is formed in the position restricting plate. Only one restriction through hole may be formed, or a plurality of restriction through holes may be provided. In the case of providing a plurality, it can be provided in a row on the position regulating plate, or can be provided at various positions. The substrate has a fifth surface arranged to face the fourth surface and a sixth surface opposite to the fifth surface. An electrical component is mounted on the fifth surface side of the substrate, and the electrical component has a curved portion whose tip is curved convexly. As the electrical component, for example, a light emitting element, specifically, a light emitting diode can be used, and an electrical operation member such as a switch can be used. The through hole is formed at a position corresponding to the electrical component, and the position restricting plate is attached to the plate-like body so that the through hole and the restricting through hole are concentric, and the restricting through hole The size of the hole is at least larger than the curved portion of the electrical component, and the curved portion of the electrical component is introduced into the restriction through hole.

  In the electrical component holder configured as described above, for example, the electrical component may be mounted in a posture different from the intended posture, but the posture is different from the restriction through hole of the position restriction plate attached to the plate-like body. When the substrate and the plate-like body are moved relatively close to each other so that the curved portions of the electric parts come into contact with each other, the electric parts having different postures are corrected to the predetermined postures during the contact. In this electric component holder, it is not necessary to form the plate-like body and the position restricting plate in a box shape, and it is only necessary to combine the two so that the manufacture becomes easy.

  A light emitting element can be used as the electrical component. In this case, the center axis of the plate-like body and the optical axis of the light emitting element can be easily matched.

  A plurality of the electrical parts, the through holes, and the restriction through holes can be provided. When configured in this way, the configuration of the electrical component holder can be simplified even when electrical components are arranged corresponding to a plurality of through holes at different positions of the plate-like body, and the manufacture is easy. Become.

  A protrusion formed on one of the second surface of the plate-like body and the third surface of the position restricting plate is engaged with a receiving portion formed on the other to position both of them. Can do.

  The electrical component may be introduced into the regulation through hole. If comprised in this way, even if it is an electrical component which protrudes outside from the through-hole of a plate-shaped object, for example, it is applicable. In addition, since not only the tip of the electrical component but also the whole is disposed in the through hole for regulation, when the electrical component is a light emitting component such as an LED, light does not leak and the visibility is further improved.

  As described above, according to the electric component holder of the present invention, the electric component can be positioned and arranged on the plate-like body with a simple structure so that it can be observed from the outside or can be operated from the outside.

It is a figure which shows the procedure of the assembly operation | work of the electrical component holder of one Embodiment of this invention. It is the front view and back view of a panel board used for the electric component holder of FIG. It is a rear view of the state which attached the position control board to the electrical component holder of FIG.

  An electrical component holder according to an embodiment of the present invention is obtained by implementing the present invention on an operation display unit of a power supply device for an electric device, for example, a welding machine. As shown in FIG. 2 has. FIG. 1 is an end view taken along the line AA of FIG. In a state in which the electrical component holder is attached, the substrate 4 is disposed on the back side of the panel plate 2 with a predetermined distance from the panel plate 2 as shown in FIG. An electrical component having a plurality of curved portions whose tips are convexly curved, for example, a plurality of light emitting elements, specifically, an LED 6, for example, an operation component, specifically, a switch or a rotary encoder 8, is attached to the substrate 4. Can be observed from the front side of the panel plate 2, and the switch can be operated from the front side of the panel plate 2.

  The panel board 2 is formed in a rectangular shape as shown in FIGS. 2A and 2B, and has a first surface, for example, a front surface 10 and a second surface, for example, a rear surface 12 opposite thereto. Yes. As shown in FIG. 1 (a), a plurality of through holes 14 and operation holes 16 are formed so as to penetrate between these. The through hole 14 is for observing the LED 6 from the front 10 side of the panel plate 2 as described above. The operation hole 16 is for enabling the switch and the rotary encoder 8 to be operated from the front surface 10 side of the panel plate 2 and is formed at various positions on the panel plate 2 as shown in FIG. ing. Since all the LEDs 6 used are the same, the through holes 14 are all circular holes having the same diameter. The operation hole 16 may be circular or bowl-shaped depending on the corresponding switch or rotary encoder 8. Also, the diameter of the operation hole 16 having the same shape varies depending on the size of the corresponding switch or rotary encoder 8.

  At the four corners of the panel plate 2, as shown in FIG. 1 (d), one end of a spacing holder for attaching the panel plate 2 to the substrate 4 at a predetermined distance, for example, a columnar spacer 18 is attached. ing.

  Further, as shown in FIG. 2A, a seal 20 is stuck on the entire front surface 10 of the panel 2. As shown in FIG. 2A, a frame is printed on the seal 20 so as to show each switch and each rotary encoder 8 and an LED whose light emission state changes in accordance with the operation state, and only a part thereof is printed. As shown, characters for displaying the functions of the switch and the rotary encoder 8 are printed. Further, the operation hole 16 corresponding to the push button switch is covered with a seal 20, a mark indicating the position is printed, and this can be operated from above the seal.

  A hole 22 is formed at the position of the seal corresponding to the operation hole 16 corresponding to the switch protruding from the panel plate 2 or the rotary encoder 8. The shape and size of the hole 22 are formed in a shape corresponding to each corresponding switch and each rotary encoder 8. In addition, a transparent or translucent window 24 having the same size as the through hole 14 is formed at a position corresponding to the through hole 14 corresponding to the LED 6 of the seal 20. Instead of the window 24, a hole can be formed in the seal 20 at the position where the window 24 is formed.

  A position restricting plate 26 is disposed on the back surface 12 side of the panel plate 2. The position restricting plate 26 is formed in a rectangular shape smaller than the panel plate 2. As shown in FIG. 1 (a), the position restricting plate 26 has a front face 28 and a rear face 30, and as shown in FIG. 1 (b), the front face 28, which is the third face of the position restricting plate 26, is a panel plate. 2 is attached to the rear surface 12 which is the second surface.

  In this attached state, restriction through holes 32 are respectively formed in the position restricting plate 26 at positions corresponding to the through holes 14 of the panel plate 2. These restricting through holes 32 are circular ones somewhat larger than the LED 6. In addition, a passage hole 34 having a shape that is slightly larger than the operation hole 16 through which the rotary encoder 8 can pass is formed at a position corresponding to the operation hole 16 of the panel plate 2. The position restricting plate 26 is positioned with respect to the panel plate 2 such that the restricting through hole 32 and the through hole 14 are concentric and the passing hole 34 is concentric with the operation hole 16 of the panel plate 2. To do. In this example, for positioning, protrusions such as dowels 36 are projected from the back surface 12 at two locations on the back surface 12 of the panel plate 2 as shown in FIG. The position restricting plate is configured to receive the dowel 36 in a state where the restricting through hole 32 is concentric with the through hole 14 of the panel plate 2 and the passage hole 34 is concentric with the operating hole 16 of the panel plate 2. 26 is formed with a receiving portion 38.

  As shown in FIG. 1B, the substrate 4 has a fifth surface, for example, a front surface 40, and a sixth surface, for example, a rear surface 42. As shown in FIG. 4D, the substrate 4 is coupled to the other end of the spacer 18 so that the front face 40 maintains a predetermined distance from the rear face 12 of the panel plate 2. Each LED 6 mounted on the front surface 40 side of the substrate 4 is disposed at a position corresponding to the through hole 14 of the panel plate 2, and a switch or rotary encoder 8 is disposed at a position corresponding to the operation hole 16. Soldered to a wiring pattern (not shown).

  Each LED 6 is soldered to the substrate 4, and the tip end side is convexly curved toward the position regulating plate 26. Each LED 6 preferably has a posture in which its optical axis coincides with the central axis of the corresponding through hole 14. However, each LED 6 is soldered to the substrate 4 by, for example, reflow soldering. At that time, the substrate 4 may be subjected to vibration, and the LED 6 is a component whose lead is inserted into the substrate 4. As shown in FIG. 1B, the optical axis is not perpendicular to the substrate 4 but may be inclined and soldered in a posture different from a desired posture. If the substrate 4 is attached to the panel plate 2 with the LED 6 having a different posture, the optical axis does not coincide with the central axis of the corresponding through hole 14, and the LED 6 with poor visibility exists. For this reason, operations such as correcting the posture of the LED 6 occur, and the manufacturing efficiency is significantly deteriorated. In order to improve this point, the position restricting plate 26 having the above-described configuration is provided.

  That is, as shown in FIG. 1A, the front surface 28 of the position regulating plate 26 is positioned on the back surface 12 side of the panel plate 2, and both are brought into contact with each other as shown in FIG. At this time, the two dowels 36 are inserted and fitted into the corresponding two receiving portions 38, and the through hole 14 of the panel plate 2 and the restricting through hole 32 of the position restricting plate 26 are positioned so as to be concentric. Arranged. The position restricting plate 26 may be fixed to the panel plate 2 by fixing means such as screws.

  The panel plate 2 to which the position restricting plate 26 is attached is arranged so that the back surface 30 of the position restricting plate 26 is positioned on the front surface 40 side of the substrate 4 as shown in FIG.

  Then, as shown in FIG. 5C, the panel plate 2 and the substrate 4 are connected so that the switch and the rotary encoder 8 are inserted into the passage hole 34 of the position restricting plate 26 and the operation hole 16 of the panel plate 2. The panel plate 2, the regulating through hole 32, and the substrate 4 are relatively moved to a parallel position. Then, the panel board 2 and the board | substrate 4 are fixed through the spacer 18, and both are attached.

  Here, the size of the restriction through hole 32 will be described. When the optical axis of the LED 6 is inclined with respect to the substrate 4, the restriction through hole 32 may come into contact with the edge of the restriction through hole 32 when the curved portion is positioned in the inclination direction of the LED 6. It is formed in a size that can be done. That is, when the optical axis of the LED 6 is mounted in a correct posture perpendicular to the substrate 4, the restriction through-hole 32 is large enough to be inserted without interfering with the curved portion at the tip of the LED 6. That's it. When the panel plate 2 and the substrate 4 are brought close to each other, the curved LED 6 is pushed toward the center of the restricting through hole 32 by the edge of the restricting through hole 32, so that the LED 6 enters the restricting through hole 32. As shown in FIG. 4D, the posture is corrected so that the optical axis of the LED 6 faces the center direction of the restricting through hole 32 and substantially coincides with the through hole 14 of the panel plate 2. . Then, the other ends of the spacers 18 are respectively attached to the substrate 4, and the panel plate 2 and the substrate 4 are combined.

  By providing the position regulating plate 26 on the back side of the panel plate 2 in this way, even if the LED 6 on the substrate 4 is inclined, it is inclined when the panel plate 2 and the substrate 4 are attached. The posture of the LED 6 can be corrected, and the posture correction work is easy. Moreover, the only additional part necessary for posture control is the position restricting plate 26, and the plate-like position restricting plate 26 is only attached to the back side of the panel plate 2. Therefore, manufacture of this holder becomes easy. In addition, the workability is improved because the work of correcting the posture of the LED 6 is not required. Furthermore, even if the LEDs 6 are not arranged in a row at various positions on the substrate 4, the LEDs 6 can be freely arranged.

  After the panel plate 2 and the substrate 4 are attached, the seal 20 is attached to the front 10 side of the panel plate 2 as shown in FIG. When the panel plate 2 and the substrate 4 are combined, a plurality of operation components protrude from the operation holes 16 on the front surface 10 of the panel plate 2. In this example, two rotary encoders 8 among a plurality of operation parts are inserted into corresponding holes 22 of the seal 20 for positioning the seal 20. By inserting the rotary encoder 8 into the hole 22 of the seal 20, the seal 20 can be positioned at the correct sticking position on the front surface 10 side of the panel plate 2. By doing so, the seal 20 is stuck at the correct sticking position without being displaced with respect to the panel plate 2, so that the transparent or translucent window 24 of the seal 20 is provided with the regulation through-hole 32 and the through-hole 14. It is stuck so that it is located right above. As described above, since the posture of the LED 6 is corrected and the optical axis faces the window 24, the display of the LED 6 can be clearly recognized.

  In the above embodiment, the LED 6 and the switch or the rotary encoder 8 are used. However, only the LED 6 can be used. Although the LED 6 is used as an electrical component, the present invention is not limited to this, and other electrical components can be used as long as the electrical component has a curved portion that can come into contact with the regulation through hole 32 at the tip. Although the panel board 2, the board | substrate 4, and the position control board 26 showed the rectangular thing, it is not restricted to this, It is set as another shape, for example, circular or a polygon, according to the place of the electric equipment to which these are attached. You can also. Since the LED 6 is used for the through-hole 14 and the regulation through-hole 32, both are circular holes, but other shapes may be used according to the front shape of the electric component to be used. Further, the LED 6 is configured such that the tip portion is partially inserted into the restriction through hole 32, but the entire LED 6 may be inserted into the restriction through hole 32. Although the dowel 36 is provided on the back surface 12 of the panel plate 2 and the receiving portion 38 is provided on the front surface 28 of the position restricting plate 26, the dowel is provided on the front surface 28 of the position restricting plate 20. It can also be provided on the back surface 12. The receiving portion 38 need not be a through hole as long as it can accommodate and restrain the dowel 36 inside, and may be a concave portion, for example.
