Description

本発明は、電子機器の筐体内に収容された回路基板と該基板と協働する構成部材と、を含む電子機器の筐体構造に関する。   The present invention relates to a housing structure of an electronic device including a circuit board housed in the housing of the electronic device and a component member that cooperates with the substrate.

電子回路を担う回路基板へ実装される部品(受動部品、能動部品、機構部品等)の載置には、表面実装技術(SMT:Surface Mounting Technology)が多用されている。SMTは、回路基板上に形成した接合パッド上にスルーホールを用いることなく直接部品をはんだ付けできる故に、回路基板への部品実装における利点が多い。   Surface mounting technology (SMT) is often used for mounting components (passive components, active components, mechanical components, etc.) mounted on a circuit board that carries an electronic circuit. SMT has many advantages in mounting components on a circuit board because components can be soldered directly onto a bonding pad formed on the circuit board without using a through hole.

特許文献1には、表面実装技術等により押釦スイッチが回路基板上に固定され、筐体に設けられた弾性片を介して該スイッチのボタン部を押す電子機器のスイッチ構造が開示されている。   Patent Document 1 discloses a switch structure of an electronic device in which a push button switch is fixed on a circuit board by a surface mounting technique or the like and a button portion of the switch is pushed through an elastic piece provided on a housing.

特開平09−288925号公報JP 09-288925 A

しかしながら、特許文献1に記載された従来の電子機器のスイッチ構造においては、スイッチと協働する構成部材である弾性片を、筐体と一体的に又は板バネ等で形成して筐体に設けている。構成部材の弾性片は、製造上の制約により、筐体の別部品として固定した場合、固定基準が異なるため、部品誤差組立による傾きにより位置関係がずれてしまう。そのため、押釦スイッチの押圧による電源のオン/オフ動作ができない、押釦スイッチを押し過ぎてしまい押釦スイッチを破損してしまう等の問題があった。SMTによるスイッチは回路基板のスルーホールに挿入される脚部を有していない故に、剪断方向への抵抗力は低く、弾性片の操作により素子が容易に回路基板から剥離し易い課題もある。   However, in the conventional electronic device switch structure described in Patent Document 1, an elastic piece, which is a component that cooperates with the switch, is formed integrally with the housing or by a leaf spring or the like and provided in the housing. ing. When the elastic pieces of the constituent members are fixed as separate parts of the housing due to manufacturing restrictions, the fixing reference is different, and the positional relationship is shifted due to the inclination due to component error assembly. For this reason, there are problems that the power on / off operation cannot be performed by pressing the push button switch, the push button switch is pushed too much, and the push button switch is damaged. Since the switch by SMT does not have the leg part inserted in the through hole of the circuit board, the resistance in the shearing direction is low, and there is a problem that the element is easily peeled off from the circuit board by the operation of the elastic piece.

本発明は、以上の従来技術の問題点に鑑みなされたものであり、その目的は、回路基板と協働する構成部材と回路基板との組立を容易としつつ組立強度を改善する電子機器の筐体構造を提供することを目的とする。   The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to provide an electronic device housing that improves the assembly strength while facilitating the assembly of a component that cooperates with a circuit board and the circuit board. The object is to provide a body structure.

Further, the housing body 11 is provided with locking portions 11Sa and 11Sb (side surfaces of the ribs 11LB) corresponding to the claws 14Na and 14Nb, and when the clamping portions are fitted, the claws 14Na and 14Nb are locked to the locking portions 11Sa and 11Sb. The entire component member 14 is configured not to move in the pressing direction.

図4、5に示すように、構成部材14の挟持部14Sa、14Sbの間に設けられた突出部14Pの各々は、これを中心に設けられた円弧形状の長孔に囲まれた可動部KTの押圧部である。可動部KTは、円弧形状の長孔以外の首部で固定されている故に、外圧が加われば可動部KT自体の弾性により首部の周りに押圧方向に撓んで変形し、突出部14Pの各々が押圧方向に可動となる。図5に示すように、可動部KTの各突出部14Pの裏側(外部に露出する側)には突出部14Pとは反対に突出するレバーキートップ部KTTが設けられ、外圧を受けるように構成されている。   As shown in FIGS. 4 and 5, each of the projecting portions 14P provided between the sandwiching portions 14Sa and 14Sb of the component member 14 is a movable portion KT surrounded by an arc-shaped long hole provided at the center thereof. It is a pressing part. Since the movable portion KT is fixed at the neck portion other than the arc-shaped long hole, if an external pressure is applied, the elastic portion of the movable portion KT itself bends and deforms in the pressing direction around the neck portion, and each of the projecting portions 14P is pressed. Movable in the direction. As shown in FIG. 5, a lever key top portion KTT that protrudes opposite to the protrusion 14P is provided on the back side (side exposed to the outside) of each protrusion 14P of the movable portion KT, and is configured to receive external pressure.

As shown in FIG. 7, the component member 14 is fitted to the rod-shaped portions 11Pa and 11Pb. Here, when the component member 14 is fitted and assembled into the housing body 11, the rod is inserted into the locking portion 11S of the housing body 11 as shown in FIG. The through holes 14Ha and 14Hb are slid and fitted into the shape portions 11Pa and 11Pb while the component member 14 is inclined obliquely. That is, the fence portions 14HH of the through holes 14Ha and 14Hb are fitted in contact with the rod-shaped portions 11Pa and 11Pb. At that time, the lever key top portion KTT is allowed to escape from the side wall of the housing body 11 and is inserted into the operation opening 11OP (FIG. 4) formed in the side wall of the housing body 11 so as to be inserted. To do. After fitting, as shown in FIG. 8B, the component member 14 has its claws 14Na and 14Nb abutting against the locking portions 11Sa and 11Sb of the housing main body 11, and its main body side edge portion Eb being the housing. Since it contacts the claws 11N of the body body 11, the entire component member 14 does not move in the pressing direction. The component member 14 is disposed so that the lever key top portion KTT loosely closes the operation opening 11OP (FIG. 4) formed in the side wall of the housing body 11.

図8(b)(c)に示すように、回路基板13を、その位置決め孔13Ha、13Hbを介してロッド形状部11Pa、11Pbに嵌合して、筐体本体11上の構成部材14の挟持部14Sa、14Sb上に積層する。なお、筐体本体11上の構成部材14の挟持部14Sa、14Sbの上面と筐体本体11のボス11Bの上面とが同一平面に位置するように予め構成されている。さらに、回路基板13には、各ボス11Bに圧入されている雌ネジ11Fsに対応する開口13SOが予め形成されている(図3)。   As shown in FIGS. 8B and 8C, the circuit board 13 is fitted into the rod-shaped portions 11Pa and 11Pb via the positioning holes 13Ha and 13Hb, and the component member 14 on the housing body 11 is sandwiched. Laminated on the portions 14Sa and 14Sb. Note that the upper surfaces of the sandwiching portions 14Sa and 14Sb of the constituent member 14 on the housing body 11 and the upper surface of the boss 11B of the housing body 11 are configured in advance so as to be on the same plane. Further, an opening 13SO corresponding to the female screw 11Fs press-fitted into each boss 11B is formed in the circuit board 13 in advance (FIG. 3).

図8(c)(d)に示すように、蓋体12を、筐体本体11上に嵌合させる。嵌合時、構成部材14の蓋側縁部Ecは蓋体12の係止部12Sに当接する。その後、蓋体12の開口12SO(図3)から、回路基板13の開口13SOを介して、筐体本体11のボス11Bの雌ネジ11Fsに対し、複数本の雄ネジMsで固定する。なお、蓋体12にも、筐体本体11のボス11Bに対応する開口12SOが貫通するボス12Bが予め形成されている。これにより、回路基板13を、構成部材14の挟持部14Sa、14Sbと筐体本体11のボス11Bの上に載せて雄ネジMsを捩じ込むと、構成部材14は筐体本体11の係止部(リブ11LB上面)と回路基板13とにより挟み付けられる状態になる。すなわち、回路基板13が所定位置に固定されると共に、構成部材14も筐体本体11の係止部11S、蓋体12の係止部12Sで所定位置に固定される。   As shown in FIGS. 8C and 8D, the lid body 12 is fitted on the housing body 11. At the time of fitting, the lid side edge portion Ec of the component member 14 abuts on the locking portion 12S of the lid body 12. After that, a plurality of male screws Ms are fixed to the female screw 11Fs of the boss 11B of the housing body 11 from the opening 12SO (FIG. 3) of the lid 12 through the opening 13SO of the circuit board 13. In addition, the boss 12B through which the opening 12SO corresponding to the boss 11B of the housing body 11 passes is also formed in the lid 12 in advance. As a result, when the circuit board 13 is placed on the sandwiching portions 14Sa and 14Sb of the component member 14 and the boss 11B of the housing body 11 and the male screw Ms is screwed in, the component member 14 locks the housing body 11. The portion (the upper surface of the rib 11LB) and the circuit board 13 are sandwiched. That is, the circuit board 13 is fixed at a predetermined position, and the component member 14 is also fixed at a predetermined position by the locking portion 11S of the housing body 11 and the locking portion 12S of the lid body 12.

図9を用いて筐体の動作を説明する。図9は図1の線BBにおける電子機器を示す概略断面図である。   The operation of the housing will be described with reference to FIG. FIG. 9 is a schematic cross-sectional view showing the electronic device taken along line BB in FIG.

図9に示すように、表面実装された押釦スイッチ15は回路基板13の先端部に固定され、筐体本体11側には、押釦スイッチ15に対峙するように構成部材14が固定配置されている。回路基板13の押釦スイッチ15を押圧時は、構成部材14を矢印方向(押圧方向)へ押すことにより、樹脂製の構成部材14が撓み、突出部14Pが押釦スイッチ15を押圧する。構成部材14の押圧時でも、回路基板13と構成部材14は共に、それらの位置決め孔、貫通孔で筐体本体11のロッド形状部11Pa、11Pbに案内され積層されている故に、動くことなく、押釦スイッチ15と構成部材14の位置関係が確保される。更に、構成部材14の押圧時に、樹脂の撓みで構成部材14が付勢されていても、構成部材14の爪14Na、14Nbと筐体本体11の爪11Nで全体は固定されている。   As shown in FIG. 9, the surface-mounted pushbutton switch 15 is fixed to the tip of the circuit board 13, and the component member 14 is fixedly disposed on the housing body 11 side so as to face the pushbutton switch 15. . When the pushbutton switch 15 of the circuit board 13 is pressed, by pressing the constituent member 14 in the direction of the arrow (pressing direction), the resin constituent member 14 is bent, and the protruding portion 14P presses the pushbutton switch 15. Even when the component member 14 is pressed, both the circuit board 13 and the component member 14 are guided and stacked by the rod-shaped portions 11Pa and 11Pb of the housing body 11 through their positioning holes and through-holes. The positional relationship between the push button switch 15 and the component member 14 is ensured. Further, even when the component member 14 is urged by the bending of the resin when the component member 14 is pressed, the whole is fixed by the claws 14Na and 14Nb of the component member 14 and the claws 11N of the housing body 11.

以上の説明から明らかなように、本実施例によれば、筐体本体11に設けたロッド形状部11Pa、11Pbに、押釦スイッチ15を押圧する構成部材14の挟持部14Sa、14Sbを嵌合させ位置ずれを防止すると共に、構成部材14を挟み込みながら、回路基板13の押釦スイッチ15の位置を規制することができる。また、構成部材14の押圧時に、樹脂の撓みで構成部材14全体が付勢されないように、爪14Na、14Nb、爪11Nで位置決め、固定できる。更に、水平方向(押圧方向)に操作する押釦スイッチ15に対し、垂直方向に装置全体の積層組立を可能とした効果も得られる。更に、構成部材14に押圧力が与えられても、押釦スイッチ15が回路基板13から脱離することを防止することができる。なお、上記実施例では、樹脂製筐体の一体成型のロッド形状部を説明したが、変形例として金属製ロッド形状部を別体として筐体本体11に固着することで形成することもできる。さらに、筐体本体11と蓋体12の係止部11S、12Sで構成部材14を固定されるならば、一本のロッド形状部のみを用いるように構成できる。また、上記実施例では、1枚の回路基板13を用いた例を説明したが、変形例として、それぞれにロッド形状部に嵌合できる位置決め孔を設けた複数の回路基板を用いるように構成できる。   As is clear from the above description, according to the present embodiment, the sandwiching portions 14Sa and 14Sb of the component member 14 that presses the pushbutton switch 15 are fitted to the rod-shaped portions 11Pa and 11Pb provided in the housing body 11. The position of the push button switch 15 on the circuit board 13 can be regulated while preventing the displacement and sandwiching the component member 14. Further, when the component member 14 is pressed, it can be positioned and fixed by the claws 14Na, 14Nb and the claws 11N so that the entire component member 14 is not biased by the bending of the resin. In addition, the push button switch 15 operated in the horizontal direction (pressing direction) can also achieve an effect of enabling the entire apparatus to be stacked and assembled in the vertical direction. Further, even when a pressing force is applied to the component member 14, the push button switch 15 can be prevented from being detached from the circuit board 13. In the above-described embodiment, the integrally molded rod-shaped portion of the resin casing has been described. However, as a modified example, the metal rod-shaped portion can be formed as a separate body and fixed to the casing body 11. Furthermore, if the structural member 14 is fixed by the locking portions 11S and 12S of the housing body 11 and the lid body 12, it can be configured to use only one rod-shaped portion. In the above-described embodiment, an example in which one circuit board 13 is used has been described. However, as a modification, a plurality of circuit boards each having a positioning hole that can be fitted into the rod-shaped portion can be used. .

図10は本発明による実施例2の電子機器を示す概略断面図である。実施例2の電子機器は、実施例1の蓋体12と筐体本体11とが筐体本体11のボス11Bと雌ネジ11Fsと協働する雄ネジMsで固定する構成に代えて、ロッド形状部11Pa、11Pbの先端にスナップ結合部11Aを設け且つ筐体本体11の内壁に対向する蓋体12の内壁にスナップ結合部11Aを嵌合する嵌合部12Aを設けた以外、実施例1の電子機器と同一である。   FIG. 10 is a schematic cross-sectional view showing an electronic apparatus of Example 2 according to the present invention. The electronic device according to the second embodiment has a rod shape instead of the configuration in which the lid body 12 and the housing body 11 of the first embodiment are fixed by the male screw Ms that cooperates with the boss 11B of the housing body 11 and the female screw 11Fs. Example 1 except that a snap coupling part 11A is provided at the tip of the parts 11Pa and 11Pb, and a fitting part 12A for fitting the snap coupling part 11A is provided on the inner wall of the lid 12 facing the inner wall of the housing body 11. It is the same as electronic equipment.

図10に示すように、蓋体12のボス12Bに対応する筐体本体11の位置に、リブ11LBとそこからボス12Bへ伸長するロッド形状部11Pa、11Pbとその先端にスナップ結合部11Aを設け、スナップ結合部11Aがそれに対応する蓋体12の開口12SOを貫通するように予め構成されている。蓋体12を筐体本体11に固定する時は、筐体本体11のロッド形状部11Pa、11Pbの先端に設けたスナップ結合部11Aが、蓋体12の嵌合部12Aの貫通孔を塞ぎながら蓋体12を固定する。これにより、筐体本体11のロッド形状部11Pa、11Pbの先端に設けたスナップ結合部11Aで蓋体12の固定が可能であり、スナップ結合部11Aでの蓋体12の傷つけ防止効果も得られる。ネジの組み立て部品点数の削減の効果も得られる。   As shown in FIG. 10, at the position of the housing main body 11 corresponding to the boss 12B of the lid 12, rod-shaped portions 11Pa and 11Pb extending from the rib 11LB to the boss 12B and a snap coupling portion 11A at the tip thereof are provided. The snap coupling portion 11A is configured in advance so as to penetrate the corresponding opening 12SO of the lid body 12. When the lid body 12 is fixed to the housing body 11, the snap coupling portion 11A provided at the tip of the rod-shaped portions 11Pa and 11Pb of the housing body 11 closes the through hole of the fitting portion 12A of the lid body 12. The lid 12 is fixed. Accordingly, the lid body 12 can be fixed by the snap coupling portion 11A provided at the tip of the rod-shaped portions 11Pa and 11Pb of the housing body 11, and the effect of preventing the lid body 12 from being damaged by the snap coupling portion 11A can be obtained. . The effect of reducing the number of assembly parts of the screw can also be obtained.
