Description
【０００１】[0001]
この考案は、プリント基板をケース内に収納固定したプリント基板固定構造に 関するものである。 The present invention relates to a printed circuit board fixing structure in which a printed circuit board is housed and fixed in a case.
【０００２】[0002]
従来のプリント基板固定構造を、図１１ないし図１４に基づいて説明する。図 １１において、６０はケースであり、ケース本体６１と蓋６２とから成る。ケー ス本体６１内には絶縁シート６３が敷いてあり、電子部品６４を実装したプリン ト基板６５がねじ６６にて固定して収納されている。さらに、ケース本体６１と 蓋６２との間には、ゴム製の防水シール６７が介装されている。 A conventional printed circuit board fixing structure will be described with reference to FIGS. In FIG. 11, reference numeral 60 denotes a case, which includes a case body 61 and a lid 62. An insulating sheet 63 is laid inside the case body 61, and a printed circuit board 65 on which an electronic component 64 is mounted is fixed by screws 66 and stored. Further, a rubber waterproof seal 67 is interposed between the case body 61 and the lid 62.
【０００３】 次に、プリント基板６５の収納作業について説明する。まず、図１２に示すよ うに、ケース本体６１内に絶縁シート６３を敷く。次に図１３に示すように、プ リント基板６５をねじ６６にてケース本体６１に固定する。そして、図１４に示 すように、防水シール６７を嵌め、蓋６２をケース本体６１にねじ止めする。Next, the work of housing the printed circuit board 65 will be described. First, as shown in FIG. 12, an insulating sheet 63 is laid inside the case body 61. Next, as shown in FIG. 13, the print substrate 65 is fixed to the case body 61 with screws 66. Then, as shown in FIG. 14, a waterproof seal 67 is fitted and the lid 62 is screwed to the case body 61.
【０００４】[0004]
しかしながら、従来のプリント基板固定構造によると、プリント基板６５をケ ース本体６１にねじ止めする際、ねじ６６の数や締結位置が、プリント基板６５ の回路によって制限されることがある。そのため、プリント基板６５の共振周波 数をある程度以上に上げることができず、プリント基板６５の表面に実装してい る電子部品６４の端子部やはんだ付け部に、プリント基板６５の共振による過大 な応力が作用し、疲労，破損の原因になるという問題があった。 However, according to the conventional printed circuit board fixing structure, when the printed circuit board 65 is screwed to the case body 61, the number of screws 66 and the fastening positions may be limited by the circuit of the printed circuit board 65. Therefore, the resonance frequency of the printed circuit board 65 cannot be raised to a certain level or more, and excessive stress due to the resonance of the printed circuit board 65 is applied to the terminals and soldered parts of the electronic components 64 mounted on the surface of the printed circuit board 65. Has a problem in that it causes fatigue and damage.
【０００５】 また、プリント基板６５を固定するためのねじ６６、絶縁シート６３、防水シ ール６７を必要とし、部品点数が多く、組立に手間がかかるという問題もあった 。 この考案の目的は、基板の共振による実装部品への悪影響を防止し、かつ部品 点数を削減したプリント基板固定構造を提供することである。Further, there is a problem that the screws 66 for fixing the printed circuit board 65, the insulating sheet 63, and the waterproof seal 67 are required, the number of parts is large, and the assembly is troublesome. An object of the present invention is to provide a printed circuit board fixing structure in which the adverse effects on the mounted components due to the resonance of the substrate are prevented and the number of components is reduced.
【０００６】[0006]
この考案のプリント基板固定構造は、ケース本体の開口部を蓋で覆ってなるケ ースと、外周縁をケース本体と蓋との間に介装してケース本体の内面に沿って設 けられ内側面に基板挿入溝を形成した防水性・弾性・絶縁性を有する保持部材と 、外周縁を基板挿入溝に挿入してケース内に収納したプリント基板とを備えたも のである。 The printed circuit board fixing structure of the present invention is provided along the inner surface of the case body with the case formed by covering the opening of the case body with the lid and the outer peripheral edge interposed between the case body and the lid. It is provided with a waterproof, elastic, and insulating holding member having a board insertion groove formed on the inner side surface, and a printed circuit board having an outer peripheral edge inserted into the board insertion groove and housed in a case.
【０００７】[0007]
この考案の構成によれば、ケース内に設けた保持部材にてプリント基板の外周 縁を保持するので、従来のねじ止めに比べ基板の共振周波数を上げることができ 、プリント基板の共振による実装部品への悪影響を防止することができる。また 、ケース本体の内面に沿って設けた防水性・弾性・絶縁性を有する保持部材は、 絶縁シートの役割を果たし、かつケース本体と蓋との間に介装されて防水シール としての役割も果たし、さらに内側面に形成した基板挿入溝にプリント基板を挿 入してプリント基板固定用としての機能をも備えており、保持部材を使用するこ とで部品点数の削減が図れる。 According to the configuration of the present invention, since the outer peripheral edge of the printed circuit board is held by the holding member provided in the case, the resonant frequency of the printed circuit board can be increased as compared with the conventional screwing, and the mounted component due to the resonance of the printed circuit board. Can be prevented from being adversely affected. Also, the waterproof, elastic, and insulating holding member provided along the inner surface of the case body serves as an insulating sheet, and is also interposed between the case body and the lid to function as a waterproof seal. Moreover, it also has the function of fixing the printed circuit board by inserting the printed circuit board into the board insertion groove formed on the inner surface, and the number of parts can be reduced by using the holding member.
【０００８】[0008]
第１の実施例 この考案の第１の実施例を図１ないし図４に示す。 図において、１０はプリント基板を収納するためのケースであり、上面が開口 した箱形のケース本体１１と、ケース本体１１の開口部を覆う蓋１２とから構成 されている。ケース本体１１の内面に沿って保持部材１３が敷いてある。保持部 材１３は、防水性・弾性・絶縁性を有したゴム製であるが、その他の樹脂等にて 形成してもよい。また、１４は表面に各種電子部品１５を実装したプリント基板 である。 First Embodiment A first embodiment of the present invention is shown in FIGS. In the figure, 10 is a case for accommodating a printed circuit board, which is composed of a box-shaped case body 11 having an open top surface and a lid 12 for covering the opening of the case body 11. A holding member 13 is laid along the inner surface of the case body 11. The holding member 13 is made of rubber having waterproofness, elasticity, and insulation, but may be made of other resin or the like. Reference numeral 14 is a printed circuit board having various electronic components 15 mounted on its surface.
【０００９】 次に、組立作業手順に従って、さらに詳細に説明する。まず、図２に示すよう に、保持部材１３にプリント基板１４を固定する。保持部材１３の内側面には水 平方向に延びる基板挿入溝１６が形成されており、プリント基板１４の外周縁を この基板挿入溝１６に挿入して固定する。なお、基板挿入溝１６は、保持部材１ ３の四側面全てに渡って設けられていて、プリント基板１４の全外周縁を保持す るようにしてもよいが、プリント基板１４の少なくとも２辺以上の縁部を保持す るような構造であればよい。さらに、保持部材１３の上端には、全周に渡って外 向きに折曲した鍔部１７が形成されている。Next, a more detailed description will be given according to the assembly work procedure. First, as shown in FIG. 2, the printed board 14 is fixed to the holding member 13. A board insertion groove 16 extending in the horizontal direction is formed on the inner side surface of the holding member 13, and the outer peripheral edge of the printed board 14 is inserted into and fixed to the board insertion groove 16. The board insertion groove 16 may be provided on all four side surfaces of the holding member 13 so as to hold the entire outer peripheral edge of the printed board 14, but at least two sides of the printed board 14 or more. Any structure may be used as long as it holds the edge of the. Further, a flange portion 17 is formed on the upper end of the holding member 13 and is bent outwardly over the entire circumference.
【００１０】 次に、図３に示すように、保持部材１３をケース本体１１内に収納する。保持 部材１３の鍔部１７は、ケース本体１１と蓋１２との間に介装され、ケース本体 １１と蓋１２に対峙して形成した突条部１８，１９どうしの間で鍔部１７を挟圧 固定する。そして、図４に示すように、ケース本体１１と蓋１２とをトルクスね じ等のねじ２０で固定するなお、図４には、保持部材１３の図示を省略してある 。Next, as shown in FIG. 3, the holding member 13 is housed in the case body 11. The collar portion 17 of the holding member 13 is interposed between the case body 11 and the lid 12, and the collar portion 17 is sandwiched between the ridge portions 18 and 19 formed facing the case body 11 and the lid 12. Fix in pressure. Then, as shown in FIG. 4, the case body 11 and the lid 12 are fixed with screws 20 such as a Torx screw. Incidentally, the holding member 13 is not shown in FIG.
【００１１】 このように構成されたプリント基板固定構造によると、プリント基板１４は、 外周縁を保持部材１３の基板挿入溝１６に挿入して固定したので、例えばプリン ト基板１４の８箇所をねじで固定した場合に比べ、共振周波数は約２倍以上にな ることが振動解析にて確認されている。このように、共振周波数を上げることに より、車両等に設置した際に外乱によるプリント基板１４の共振を防ぐことがで きる。プリント基板１４の共振がなければ、プリント基板１４の表面に実装され ている電子部品１５に対する振動対策は、プリント基板１４からの影響を考慮す る必要がなくなるので容易になる。また、プリント基板１４の共振がなければ、 ＨＩＣ（ハイブリッドＩＣ）のように、一列に端子が並んだ電子部品の両端の端 子にかかる応力が非常に小さくなり、端子折れや半田クラック等の破損を防止す ることができる。According to the printed circuit board fixing structure thus configured, since the printed circuit board 14 is fixed by inserting the outer peripheral edge into the board insertion groove 16 of the holding member 13, for example, the eight positions of the print circuit board 14 are screwed. It has been confirmed by vibration analysis that the resonance frequency is about twice as high as that when fixed at. By increasing the resonance frequency in this way, it is possible to prevent resonance of the printed circuit board 14 due to disturbance when the printed circuit board 14 is installed in a vehicle or the like. If the printed circuit board 14 does not have resonance, measures against vibration of the electronic component 15 mounted on the surface of the printed circuit board 14 become easy because it is not necessary to consider the influence from the printed circuit board 14. If the printed circuit board 14 does not resonate, the stress applied to the terminals at both ends of an electronic component such as a HIC (Hybrid IC) in which the terminals are aligned in a row becomes extremely small, and the terminals are broken or solder cracks are damaged. Can be prevented.
【００１２】 また、防水性・弾性・絶縁性を有した保持部材１３は、ケース本体１１の内面 に沿って設けられ、プリント基板１４とケース１０との間の絶縁シートとしての 役割を果たし、かつケース本体１１と蓋１２との間に介装されて突条部１８，１ ９で挟圧されるので、防水シールとしての役割も果たし、さらに内側面に形成し た基板挿入溝１６にプリント基板１４を挿入してプリント基板固定用としての機 能をも備えており、保持部材１３を使用することで部品点数の削減が図れ、組立 作業も大幅に短縮できる。The waterproof, elastic, and insulating holding member 13 is provided along the inner surface of the case main body 11 and serves as an insulating sheet between the printed circuit board 14 and the case 10. Since it is interposed between the case main body 11 and the lid 12 and is pinched by the ridges 18 and 19, it also functions as a waterproof seal, and the printed circuit board is inserted into the board insertion groove 16 formed on the inner surface. It also has a function for fixing the printed circuit board by inserting 14 therein, and by using the holding member 13, the number of parts can be reduced and the assembling work can be significantly shortened.
【００１３】 なお、図５に示すように、保持部材１３は、プリント基板１４の全周と接して いる必要はなく、嵌め込み作業等の都合により適当に縦溝２１を設けてもよい。 また、プリント基板１４の固定は、基板挿入溝１６への挿入だけでなく、ケース 本体１１へのねじ止めと併用してもよい。 第２の実施例 この考案の第２の実施例を図６および図７に示す。As shown in FIG. 5, the holding member 13 does not have to be in contact with the entire circumference of the printed circuit board 14, and the vertical groove 21 may be appropriately provided for convenience of fitting work or the like. The printed circuit board 14 may be fixed not only by being inserted into the board insertion groove 16 but also by being screwed to the case body 11. Second Embodiment A second embodiment of the present invention is shown in FIGS. 6 and 7.
【００１４】 この実施例は、ケース３０を構成するケース本体３１を浅底とし、保持部材３ ３の鍔部３４と基板挿入溝３９を略同一の高さに形成したものである。また、ケ ース本体３１と蓋３２には、鍔部３４を挟圧する突条部３５，３６が形成されて おり、さらに保持部材３３の側壁部を上下から挟圧する突条部３７，３８が形成 されている。In this embodiment, the case main body 31 constituting the case 30 has a shallow bottom, and the flange portion 34 of the holding member 33 and the substrate insertion groove 39 are formed at substantially the same height. Further, the case main body 31 and the lid 32 are formed with ridges 35 and 36 for pinching the flange 34, and further ridges 37 and 38 for pinching the side wall of the holding member 33 from above and below. Has been formed.
【００１５】 このように構成されたプリント基板固定構造においても、第１の実施例と同様 の効果が得られる。さらに、ケース本体３１を浅底としたことで、保持部材３３ の形状を小さくでき、コストダウンが図れる。また、保持部材３３は、ケース本 体３１の突条部３５，３７と蓋３２の突条部３６，３８の２箇所にて挟圧固定さ れているので、防水性が向上する。また、突条部３７，３８にて保持部材３３の 側壁部を挟持することで、基板挿入溝３９に挿入したプリント基板１４の外周縁 も挟圧固定され、プリント基板１４の固定がより一層強固となる。さらに、図７ に示すように、ケース本体３１の下面からねじ４１を挿通して蓋３２に締結し、 ケース本体３１と蓋３２を固定し、ねじ４１の頭部はケース本体３１の下面の凹 部４０内に収納される。よって、ケース３０を車両等に取付けた場合、ねじ４１ の頭部がケース３０と車両間にあり、ユーザーが誤ってねじ４１を外し、高電圧 部に触れるという危険が大幅に減少する。Also in the printed circuit board fixing structure thus configured, the same effect as that of the first embodiment can be obtained. Further, since the case main body 31 has a shallow bottom, the shape of the holding member 33 can be reduced, and the cost can be reduced. Further, since the holding member 33 is clamped and fixed at two places, the ridges 35 and 37 of the case body 31 and the ridges 36 and 38 of the lid 32, the waterproof property is improved. Further, by sandwiching the side wall portion of the holding member 33 with the ridges 37 and 38, the outer peripheral edge of the printed circuit board 14 inserted into the substrate insertion groove 39 is also clamped and fixed, so that the printed circuit board 14 is more firmly fixed. Becomes Further, as shown in FIG. 7, the screw 41 is inserted from the lower surface of the case main body 31 and fastened to the lid 32 to fix the case main body 31 and the lid 32, and the head of the screw 41 has a concave portion on the lower surface of the case main body 31. It is stored in the section 40. Therefore, when the case 30 is attached to a vehicle or the like, the head of the screw 41 is located between the case 30 and the vehicle, and the risk of the user accidentally removing the screw 41 and touching the high-voltage portion is greatly reduced.
【００１６】 第３の実施例 この考案の第３の実施例を図８に示す。この実施例は、第２の実施例において 、保持部材３３の基板挿入溝３９の上部４５を切断したものである。このように 構成されたプリント基板固定構造においても、第２の実施例と同様の効果が得ら れる。さらに、基板挿入溝３９の上部４５を切断したので、プリント基板１４を 基板挿入溝３９へ挿入し易くなる。なお、保持部材３３の基板挿入溝３９の下部 を切断しても同様の効果が得られる。Third Embodiment A third embodiment of the present invention is shown in FIG. In this embodiment, the upper portion 45 of the substrate insertion groove 39 of the holding member 33 is cut off in the second embodiment. Also in the printed circuit board fixing structure configured as described above, the same effect as that of the second embodiment can be obtained. Further, since the upper portion 45 of the board insertion groove 39 is cut, the printed board 14 can be easily inserted into the board insertion groove 39. The same effect can be obtained by cutting the lower part of the substrate insertion groove 39 of the holding member 33.
【００１７】 第４の実施例 この考案の第４の実施例を図９に示す。この実施例は、ケース５０のケース本 体５１と蓋５２の接合部近傍に位置して、保持部材５３に基板挿入溝５６を形成 したものであり、保持部材５３の側壁部が突条部５４，５５にて挟圧固定されて いる。このように構成されたプリント基板固定構造においても、第２の実施例と 同様の効果が得られる。Fourth Embodiment A fourth embodiment of the present invention is shown in FIG. In this embodiment, a board insertion groove 56 is formed in a holding member 53 in the vicinity of a joint between a case body 51 and a lid 52 of a case 50, and a side wall portion of the holding member 53 has a ridge 54. It is clamped and fixed by 55. Also in the printed circuit board fixing structure thus configured, the same effect as that of the second embodiment can be obtained.
【００１８】 第５の実施例 この考案の第５の実施例を図１０に示す。この実施例は、第４の実施例におい て、保持部材５３の側壁部の上下面５７，５８を、外側が薄肉厚となるように傾 斜させたものである。このように構成されたプリント基板固定構造においても、 第４の実施例と同様の効果が得られる。さらに、ケース本体５１と蓋５２をねじ 止めした際、プリント基板１４が保持部材５３にてより強く挟圧固定される。し たがって、プリント基板１４を保持部材５３の基板挿入溝５６に挿入し易くする ために、保持部材５３の硬度を軟化させた場合でも、プリント基板１４を強固に 固定することができる。Fifth Embodiment FIG. 10 shows a fifth embodiment of the present invention. In this embodiment, in the fourth embodiment, the upper and lower surfaces 57 and 58 of the side wall portion of the holding member 53 are tilted so that the outside has a thin thickness. Also in the printed circuit board fixing structure thus configured, the same effect as that of the fourth embodiment can be obtained. Further, when the case body 51 and the lid 52 are screwed together, the printed board 14 is more firmly pinched and fixed by the holding member 53. Therefore, in order to facilitate the insertion of the printed board 14 into the board insertion groove 56 of the holding member 53, the printed board 14 can be firmly fixed even if the hardness of the holding member 53 is softened.
