Description

本発明は、基板を収容したケース体内に充填材を充填する電気機器に関する。   The present invention relates to an electrical device that fills a case body containing a substrate with a filler.

従来、電子部品を実装した基板を、金属製などの箱状のケース体に収容する場合には、電子部品の温度低減や外部からの水気の侵入の防止のために、ケース体内に液状の充填材として樹脂を盛り上げ、この樹脂を押し広げるように基板をケース体に取り付けた後、この樹脂を熱硬化させる製造方法が知られている(例えば、特許文献1参照。)。
特開2002−141676号公報(第3−4頁、図1−2)
Conventionally, when a board on which electronic components are mounted is housed in a box-like case body made of metal or the like, the case body is filled with a liquid in order to reduce the temperature of the electronic components or prevent water from entering from the outside. A manufacturing method is known in which a resin is raised as a material, a substrate is attached to a case body so as to spread the resin, and then the resin is thermally cured (see, for example, Patent Document 1).
JP 2002-141676 A (page 3-4, Fig. 1-2)

しかしながら、上述の電気機器の製造方法では、樹脂を押し広げるように基板をケース体に取り付けることから、基板の周辺部などに樹脂が充填されない部分が形成されるおそれがある。このように樹脂が充填されない部分が形成されないようにするためには、ケース体内に樹脂を予め多めに盛り上げておかなければならない。   However, in the above-described method for manufacturing an electrical device, since the substrate is attached to the case body so as to spread the resin, there is a possibility that a portion where the resin is not filled is formed in the peripheral portion or the like of the substrate. In order to prevent a portion not filled with the resin from being formed in this way, it is necessary to increase the amount of resin in the case body in advance.

そこで、筒状に形成したケース体に基板を軸方向に沿って収容し、ケース体の一端側の開口部から樹脂を充填した後、このケース体の開口部を閉塞した状態でこのケース体を横置きにして、この状態で樹脂を硬化させることで、比較的形成が容易で汎用性があるケース体を用いつつ、充填するために使用する樹脂量を低減する方法が考えられる。   Therefore, the substrate is accommodated along the axial direction in the case body formed in a cylindrical shape, and after filling the resin from the opening on one end side of the case body, the case body is closed with the opening of the case body closed. A method of reducing the amount of resin used for filling can be considered by using the case body that is relatively easy to form and versatile by curing the resin in this state in a horizontal orientation.

このような方法の場合には、樹脂が硬化する前にケース体を横置きにするため、ケース体の開口部を閉塞する蓋部から液状の樹脂が漏れ出さないように液密に封止処理を行う必要がある。特に、蓋部の外面側に端子台を取付ける場合には、基板から導出された内部リード線を端子台に配線するために内部リード線を挿通させる挿通孔を蓋部に形成する必要があり、この挿通孔に対して封止処理を行っている。   In the case of such a method, since the case body is placed horizontally before the resin is cured, a liquid-tight sealing process is performed so that the liquid resin does not leak from the lid portion that closes the opening of the case body. Need to do. In particular, when the terminal block is attached to the outer surface side of the lid portion, it is necessary to form an insertion hole in the lid portion through which the internal lead wire is inserted in order to wire the internal lead wire led out from the substrate to the terminal block. A sealing process is performed on the insertion hole.

ところが、蓋部の挿通孔は端子台を蓋部の外面側に取付けた後に端子台によって塞がれてしまうため蓋部の外面側から直接封止処理を行うことができない。このため、端子台の周縁と蓋部の外面側との隙間をシリコーン樹脂等のシール剤で防水処理を行う必要があり、封止処理が煩雑であるとともに、封止処理の材料コストが高くなってしまう。また、蓋部の挿通孔に防水用ブッシング等の部材を装着する手段も考えられるが、充填した樹脂は硬化処理されるため、硬化後には防水機能は実質不要であり、高価な防水用部材を使用することは控えるのが好ましい。   However, since the insertion hole of the lid portion is closed by the terminal block after the terminal block is attached to the outer surface side of the lid portion, the sealing process cannot be performed directly from the outer surface side of the lid portion. For this reason, it is necessary to waterproof the gap between the peripheral edge of the terminal block and the outer surface side of the lid with a sealing agent such as silicone resin, which makes the sealing process complicated and increases the material cost of the sealing process. End up. In addition, a means for attaching a member such as a waterproof bushing to the insertion hole of the lid may be considered, but since the filled resin is cured, the waterproof function is substantially unnecessary after curing, and an expensive waterproof member is required. It is preferable to refrain from using it.

本発明は、このような点に鑑みなされたもので、ケース体内に充填した充填材が蓋部から漏れ出さないような封止処理を比較的安価で簡単に行うことが可能な電気機器を提供することを目的とする。   The present invention has been made in view of the above points, and provides an electrical device capable of performing sealing processing relatively inexpensively and easily so that the filler filled in the case body does not leak from the lid. The purpose is to do.

請求項1の電気機器は、筒状に形成され、少なくとも一端側に開口部を有するとともに、軸方向に沿って一対の保持部が形成されたケース体と;板状に形成され、前記筒状のケース体の内部の一対の保持部に側部が保持された状態で前記ケース体に収容される基板と;この基板に実装された電子部品と;前記開口部から前記ケース体内に充填され、前記電子部品の少なくとも一部が基板面に対して上側となるように前記ケース体を配置した状態で硬化される充填材と;ケース体の開口部に取付けられ、基板から導出された内部リード線を挿通する挿通孔が形成された平板状の蓋部と;端子孔を有し、蓋部の挿通孔に端子孔が対向するように蓋部の外面側に取付けられた端子台と;端子孔の周囲に環状に配設され、端子台を蓋部の外面側に取付けたときに蓋部の外面側と端子台との間で挟着される発砲材料で形成された弾性封止部材と;を具備していることを特徴とする。   The electrical device according to claim 1 is formed in a cylindrical shape, and has a case body having an opening on at least one end side and a pair of holding portions formed along the axial direction; A substrate housed in the case body in a state where the side portions are held by a pair of holding parts inside the case body; an electronic component mounted on the substrate; and the case body is filled from the opening, A filler that is cured in a state in which the case body is arranged so that at least a part of the electronic component is on the upper side with respect to the board surface; and an internal lead wire that is attached to the opening of the case body and led out from the board A plate-like lid portion formed with an insertion hole for inserting the terminal block; a terminal block having a terminal hole and attached to the outer surface side of the lid portion so that the terminal hole faces the insertion hole of the lid portion; The terminal block is attached to the outer surface of the lid. Characterized in that it comprises a; and an elastic sealing member formed of a foamed material which is pinched between the outer surface side and the terminal block of the lid when the.

ケース体は、例えば、金属などにより筒状に押し出し形成されたものなどが用いられる。   As the case body, for example, a case body that is extruded and formed in a cylindrical shape by metal or the like is used.

基板は、例えば、複数の電子部品が実装された回路基板であり、例えば、電子部品を両面に実装した両面実装プリント配線基板などが用いられる。   The board is, for example, a circuit board on which a plurality of electronic components are mounted. For example, a double-sided mounting printed wiring board on which electronic components are mounted on both sides is used.

充填材は、例えば、ウレタンやシリコーン樹脂などの流動性、放熱性および絶縁性に優れた熱硬化性の部材が用いられる。   As the filler, for example, a thermosetting member having excellent fluidity, heat dissipation, and insulating properties such as urethane and silicone resin is used.

一対の保持部は、ケース内側に設けられた基板を所定の位置に保持する部分であり、基板を保持可能な構成であればよい。   The pair of holding portions are portions that hold the substrate provided inside the case at a predetermined position, and may be any configuration as long as the substrate can be held.

蓋部は、ケース体の開口部を閉塞する部材であり、開口部を閉塞した状態で基板から導出された内部リード線を挿通する挿通孔が平板状の基体に形成されている。   The lid is a member that closes the opening of the case body, and an insertion hole through which the internal lead wire led out from the substrate is closed is formed in the flat substrate.

端子台は、蓋部の外面側に取付けられるものであり、電源線または他の電気機器との接続線が入力される入力端子を備えているものである。また、蓋部の挿通孔を介して配線される内部リード線が挿入される端子孔も有している。端子台は、端子孔が蓋部の挿通孔に対向する位置関係を持って蓋部の外面側に取付けられる。   A terminal block is attached to the outer surface side of a cover part, and is provided with the input terminal into which a connection line with a power wire or another electric equipment is input. Moreover, it has a terminal hole in which the internal lead wire wired through the insertion hole of a cover part is inserted. The terminal block is attached to the outer surface side of the lid portion with a positional relationship in which the terminal hole faces the insertion hole of the lid portion.

弾性封止部材は、端子孔の周囲に配設される平坦な環状部材であり、合成樹脂製の発砲材料で形成されていて、硬度はゴムや樹脂製シール部材などと比較して低く、弾性を有するが容易に変形が可能なものが使用される。   The elastic sealing member is a flat annular member disposed around the terminal hole, and is made of a synthetic resin foam material. Its hardness is lower than that of rubber or resin sealing members, and it is elastic. However, it can be easily deformed.

そして、弾性封止部材は、蓋部の外面側と端子台との間に配設され、端子台を蓋部の外面側に取付けたときの応力によって蓋部の外面側と端子台との間で挟着され、厚さが小さくなるように変形して密度が高くなる。これによって端子孔と挿通孔との間を液密に封止処理することが可能となり、特別な封止処理や部材を必要としない。充填した樹脂は粘性物質であるため高度な液密状態は不要であり、また硬化処理されるため弾性封止部材には高度な耐久性は必要ないため、合成樹脂製の発砲材料でも十分な封止処理を行うことができる。   The elastic sealing member is disposed between the outer surface side of the lid portion and the terminal block, and is formed between the outer surface side of the lid portion and the terminal block by stress when the terminal block is attached to the outer surface side of the lid portion. And is deformed so as to reduce the thickness, thereby increasing the density. This makes it possible to liquid-tightly seal between the terminal hole and the insertion hole, and no special sealing process or member is required. Since the filled resin is a viscous substance, it does not require a high degree of liquid-tightness, and since it is cured, the elastic sealing member does not require a high degree of durability. Stop processing can be performed.

請求項2は、請求項1記載の電気機器において、前記蓋部と前記ケース体の開口部との間にシート状のパッキンが配設されており、このパッキンは前記蓋部に貼着されていることを特徴とする。   According to a second aspect of the present invention, in the electric device according to the first aspect, a sheet-like packing is disposed between the lid portion and the opening of the case body, and the packing is adhered to the lid portion. It is characterized by being.

パッキンが蓋部に貼着されているため、蓋部と開口部との封止性能が向上し、蓋部とパッキンとを一体的に開口部に取付けることができるので製造工程も簡略化される。   Since the packing is attached to the lid, the sealing performance between the lid and the opening is improved, and the manufacturing process can be simplified because the lid and the packing can be integrally attached to the opening. .

請求項3は、請求項2記載の電気機器において、前記ケース体の側縁部にはねじ溝が設けられており、このねじ溝に対向する前記蓋部の部位にはねじ挿通孔が設けられ、前記蓋部のパッキン側の面にはパッキン側に突出する突条が前記ねじ挿通孔を囲むように形成されていることを特徴とする。   According to a third aspect of the present invention, in the electric device according to the second aspect, a screw groove is provided in a side edge portion of the case body, and a screw insertion hole is provided in a portion of the lid portion facing the screw groove. A protrusion protruding toward the packing is formed on the packing-side surface of the lid so as to surround the screw insertion hole.

蓋部のパッキン側の面に突設された突条は、蓋部を開口部に取付けたときにパッキンをねじ挿通孔の周囲に沿って押圧するので、パッキンの液密性能を向上させることができ、蓋部と開口部との封止性能が向上する。   The protrusion protruding on the packing side surface of the lid part presses the packing along the periphery of the screw insertion hole when the lid part is attached to the opening, so that the liquid tightness of the packing can be improved. This can improve the sealing performance between the lid and the opening.

本発明の電気機器によれば、発砲材料で形成された弾性封止部材が端子台を蓋部の外面側に取付けたときの応力によって厚さが小さくなるように変形して密度が高くなり、端子孔と挿通孔との間を液密に封止処理することが可能となって特別な封止処理や部材が必要ない。充填した樹脂は粘性物質であるため高度な液密状態は不要であり、また硬化処理されるため弾性封止部材には高度な耐久性は必要ないため、合成樹脂製の発砲材料でも十分な封止処理を行うことができる。このように、発砲材料で形成された弾性封止部材によってケース体内に充填した充填材が蓋部から漏れ出さないような封止処理を比較的安価で簡単に行うことができる。   According to the electrical device of the present invention, the elastic sealing member formed of the foaming material is deformed so that the thickness is reduced by the stress when the terminal block is attached to the outer surface side of the lid, and the density is increased. Since the terminal hole and the insertion hole can be sealed in a liquid-tight manner, no special sealing process or member is required. Since the filled resin is a viscous substance, it does not require a high degree of liquid-tightness, and since it is cured, the elastic sealing member does not require a high degree of durability. Stop processing can be performed. In this way, a sealing process that prevents the filler filled in the case body from leaking out from the lid by the elastic sealing member formed of the foaming material can be performed relatively inexpensively and easily.

以下、本発明の一実施の形態を図面を参照して説明する。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

図1ないし図4に第1の実施の形態を示し、図1は電気機器の分解斜視図、図2は電気機器に取付けられた端子台の概略断面図、図3は端子台と蓋部とを分離した状態の概略断面図、図4は電気機器の製造方法の説明図である。   1 to 4 show a first embodiment, FIG. 1 is an exploded perspective view of an electric device, FIG. 2 is a schematic sectional view of a terminal block attached to the electric device, and FIG. FIG. 4 is an explanatory view of a method for manufacturing an electric device.

図1ないし図4の電気機器は、放電灯点灯装置11であり、この放電灯点灯装置11は、ケース体12に基板13を収納して構成され、高輝度放電ランプ(HID)などの放電灯を点灯させるものである。   1 to 4 is a discharge lamp lighting device 11. The discharge lamp lighting device 11 is configured by housing a substrate 13 in a case body 12, and is a discharge lamp such as a high-intensity discharge lamp (HID). Is to light up.

ケース体12は、例えばアルミニウムなどの金属の押し出し成形などにより角筒状に形成されたケース本体15と、このケース本体15の両端部に取り付けられたシール部材であるパッキン16,17および蓋部18,19とを備えている。   The case body 12 includes, for example, a case main body 15 formed into a rectangular tube shape by extrusion molding of a metal such as aluminum, and packings 16 and 17 that are seal members attached to both ends of the case main body 15 and a lid portion 18. , 19.

押し出し成形のケース本体15は、一端部に開口部21を備えるとともに、他端部に開口部22を備えた中空筒状の堅牢な構造体であるが、共通金型にて切り出し長さを変更するだけで容易にサイズ調整が可能であり、汎用性に優れ、製造コストを抑制可能な部品である。また、このケース本体15の内側の両側部には、基板13の両側部が嵌合される一対の保持部としての溝部23,23が互いに対向して設けられている。これら溝部23,23は、軸方向である長手方向全体に亘って直線状に形成され、両端部が各開口部21,22に臨んでおり、これら溝部23,23間に基板13が嵌合・保持されることで、ケース本体15内には、基板13の一主面である表面側に第1空間部25が区画されるとともに、基板13の他主面である裏面側に第2空間部26が区画される。本実施の形態では、第1空間部25が広く、第2空間部26が狭く形成されている。   Extruded case body 15 is a hollow cylindrical solid structure with an opening 21 at one end and an opening 22 at the other end, but the cut length is changed with a common mold It is a component that can be easily adjusted in size, has excellent versatility, and can suppress manufacturing costs. Further, on both inner side portions of the case main body 15, groove portions 23 and 23 as a pair of holding portions to which both side portions of the substrate 13 are fitted are provided so as to face each other. These groove portions 23, 23 are formed linearly over the entire longitudinal direction, which is the axial direction, both end portions face each opening 21, 22, and the substrate 13 is fitted between these groove portions 23, 23. By being held, in the case body 15, the first space portion 25 is partitioned on the front surface side which is one main surface of the substrate 13, and the second space portion is formed on the back surface side which is the other main surface of the substrate 13. 26 is sectioned. In the present embodiment, the first space 25 is wide and the second space 26 is narrow.

また、開口部21は、パッキン16と蓋部18とにより覆われている。パッキン16は、ケース本体15内に充填される充填材である合成樹脂Pの隙間からの漏れを防止するもので、弾力性および可撓性を有する部材により形成されている。パッキン16の表面には粘着層が形成されていて、蓋部18の内面に貼着された状態で開口部21に取付けられる。また、蓋部18は、例えばケース本体15と同様の金属により形成され、ねじS1などによりパッキン16とともにケース本体15に固定可能である。蓋部18には、開口部21を閉塞した状態で基板13から導出された内部リード線35、35を挿通する挿通孔が形成されている。   The opening 21 is covered with the packing 16 and the lid 18. The packing 16 prevents leakage from the gap of the synthetic resin P, which is a filling material filled in the case body 15, and is formed of a member having elasticity and flexibility. An adhesive layer is formed on the surface of the packing 16, and is attached to the opening 21 in a state of being adhered to the inner surface of the lid 18. The lid 18 is made of, for example, the same metal as the case main body 15, and can be fixed to the case main body 15 together with the packing 16 with screws S1 and the like. The lid 18 is formed with an insertion hole through which the internal lead wires 35 and 35 led out from the substrate 13 with the opening 21 closed are inserted.

図2および図3を参照して、端子台51の取付け構造について説明する。蓋部18の外面側には端子台51がねじ等の手段によって取付けられている。端子台51の主面側には4つの外部リード線挿入孔52、52が設けられている。端子台51の蓋部18の外面側には端子孔53、53が設けられている。なお、外部リード線挿入孔52、52および端子孔53、53はその周囲に環状のボス部が突設されている。端子孔53、53のボス部は、端子台51を蓋部18に取付けたときに蓋部18の外面との間にわずかな隙間が形成される。この隙間は、端子台51の蓋部18側端縁に設けられたボス部よりも突出長が若干大きい当接リブによって形成される。   With reference to FIG. 2 and FIG. 3, the attachment structure of the terminal block 51 is demonstrated. A terminal block 51 is attached to the outer surface side of the lid portion 18 by means such as screws. On the main surface side of the terminal block 51, four external lead wire insertion holes 52, 52 are provided. Terminal holes 53 and 53 are provided on the outer surface side of the lid portion 18 of the terminal block 51. The external lead wire insertion holes 52 and 52 and the terminal holes 53 and 53 have an annular boss projecting around the periphery. A slight gap is formed between the boss portions of the terminal holes 53 and 53 and the outer surface of the lid portion 18 when the terminal block 51 is attached to the lid portion 18. This gap is formed by an abutment rib having a slightly longer protruding length than the boss provided at the edge of the terminal block 51 on the lid 18 side.

端子孔53、53の周囲の環状のボス部には、合成ゴムを発砲させて形成されたエプトシーラ等からなる環状の弾性封止部材54が配設される。この弾性封止部材54は内側に端子孔53と同径の孔が形成されており、ボス部とほぼ同径の環状をなし、厚さ寸法は約3mmである。弾性封止部材54は、端子台51を蓋部18の外面側に取付けたとき、蓋部18の外面と端子台51のボス部との間で挟着され、取付けたときの応力によって端子孔53のボス部と蓋部18の外面との間のわずかな隙間の寸法に弾性的に圧縮変更する。これによって端子孔53と蓋部18の挿通孔との間を液密に封止処理される。なお、充填した合成樹脂Pは粘性物質であるため高度な液密状態は不要であり、また硬化処理されるため弾性封止部材53には高度な耐久性は必要ないため、合成樹脂製の発砲材料のような安価な部材でも十分な封止処理を行うことができる。蓋部18を開口部21に取付ける前に、基板13から導出された内部リード線35、35を端子孔53に挿入する。このとき、内部リード線35の先端が蓋部18の挿通孔を覆っているパッキン16の部位を突き破り、蓋部18の挿通孔を介して端子孔53へ挿通される。また、パッキン16が蓋部に貼着されているため、蓋部18と開口部21との封止性能が向上し、蓋部18とパッキン16とを一体的に開口部21に取付けることができるので製造工程も簡略化される。   An annular elastic sealing member 54 made of an epoxy sealer or the like formed by firing synthetic rubber is disposed on the annular boss portion around the terminal holes 53 and 53. The elastic sealing member 54 has a hole having the same diameter as the terminal hole 53 on the inner side, has an annular shape having substantially the same diameter as the boss portion, and has a thickness of about 3 mm. The elastic sealing member 54 is sandwiched between the outer surface of the lid portion 18 and the boss portion of the terminal block 51 when the terminal block 51 is attached to the outer surface side of the lid portion 18, and the terminal hole 51 is caused by the stress when the terminal block 51 is attached. The compression is elastically changed to the size of the slight gap between the boss portion of 53 and the outer surface of the lid portion 18. As a result, a liquid-tight sealing process is performed between the terminal hole 53 and the insertion hole of the lid portion 18. In addition, since the filled synthetic resin P is a viscous substance, a high degree of liquid-tight state is unnecessary, and since it is cured, the elastic sealing member 53 does not need a high degree of durability. Even an inexpensive member such as a material can perform a sufficient sealing process. Prior to attaching the lid 18 to the opening 21, the internal lead wires 35 and 35 led out from the substrate 13 are inserted into the terminal holes 53. At this time, the tip of the internal lead wire 35 breaks through the portion of the packing 16 that covers the insertion hole of the lid portion 18, and is inserted into the terminal hole 53 through the insertion hole of the lid portion 18. Further, since the packing 16 is adhered to the lid, the sealing performance between the lid 18 and the opening 21 is improved, and the lid 18 and the packing 16 can be integrally attached to the opening 21. Therefore, the manufacturing process is also simplified.

また、蓋部18とケ−ス本体15の開口部21とが当接する部分に硬度が低く、弾性変形し易い粘着性テープをパッキン16の代わりに挟着してもよい。このようにすることで、抜き型もしくは成形型などの金型が必要な専用パッキンではなく汎用部材を試用することができ、材料費を抑えることが可能となる。この種のテープ材としては、発砲ブチルゴムを基材とした両面テープなどのように材厚が薄く、硬度が低く弾性変形し易いタイプで高い粘着力を有するタイプが好ましい。   Further, an adhesive tape having low hardness and easily elastically deforming may be sandwiched in place of the packing 16 at a portion where the lid 18 and the opening 21 of the case body 15 abut. By doing so, it is possible to use a general-purpose member instead of a dedicated packing that requires a die such as a punching die or a molding die, and it is possible to reduce material costs. As this type of tape material, a type having a thin material, a low hardness, a type that is easily elastically deformed, and a high adhesive force, such as a double-sided tape based on foamed butyl rubber, is preferable.

ここで、合成樹脂Pは、例えばウレタン、あるいはシリコーン樹脂などの流動性、絶縁性および放熱性を有する液状の部材で、かつ、熱硬化性の部材とする。   Here, the synthetic resin P is a liquid member having fluidity, insulation and heat dissipation, such as urethane or silicone resin, and a thermosetting member.

一方、開口部22は、パッキン17と蓋部19とにより閉塞されている。パッキン17は、パッキン16と同様に、ケース本体15内に充填される合成樹脂Pの隙間からの漏れを防止するもので、弾力性および可撓性を有する部材により形成されている。また、蓋部19は、例えばケース本体15と同様の金属により形成され、ねじS2などによりパッキン17とともにケース本体15に固定可能である。   On the other hand, the opening 22 is closed by the packing 17 and the lid 19. Like the packing 16, the packing 17 prevents leakage from the gap of the synthetic resin P filled in the case body 15, and is formed of a member having elasticity and flexibility. The lid portion 19 is made of, for example, the same metal as the case main body 15, and can be fixed to the case main body 15 together with the packing 17 by screws S2 or the like.

また、基板13は、四角形板状の基板本体31と、この基板本体31の表面、あるいは裏面に実装された点灯回路部品である電子部品32、33a、33bなどを備えている。   The substrate 13 includes a rectangular plate-shaped substrate body 31 and electronic components 32, 33a, 33b that are lighting circuit components mounted on the front surface or the back surface of the substrate body 31.

基板本体31は、例えばガラスエポキシなどの絶縁性の部材により形成されている。基板本体31の端部には、その長手方向へ突出するスペーサ42が取付けられており、基板本体31の端部とパッキン17との間で連通部を形成している。すなわち、スペーサ42の先端がパッキン17に接触することで、基板本体31の端部とパッキン17とが所定の距離だけ離間され、基板13の端部に連通部が区画される。スペーサ42は、基板本体31に略直交する方向、すなわち基板本体31の厚み方向に沿って面方向を有する板状に形成されており、溝部23,23よりも大きく形成され、基板本体31の側方に一主面が向けられている。さらに、これらスペーサ42は、例えば基板本体31の両側部から所定の距離分幅方向の中心側に位置し、溝部23,23が形成されたケース本体15の内面の両側部に当接することで、基板13の幅方向位置をケース体12に対して位置決め可能に構成されている。   The substrate body 31 is formed of an insulating member such as glass epoxy. A spacer 42 protruding in the longitudinal direction is attached to the end portion of the substrate body 31, and a communication portion is formed between the end portion of the substrate body 31 and the packing 17. That is, when the tip of the spacer 42 contacts the packing 17, the end of the substrate body 31 and the packing 17 are separated from each other by a predetermined distance, and a communication portion is defined at the end of the substrate 13. The spacer 42 is formed in a plate shape having a surface direction along a direction substantially orthogonal to the substrate body 31, that is, along the thickness direction of the substrate body 31, and is formed larger than the groove portions 23, 23, One main surface is directed towards. Furthermore, these spacers 42 are located on the center side in the width direction by a predetermined distance from both side portions of the substrate body 31, for example, by contacting both side portions of the inner surface of the case body 15 in which the groove portions 23, 23 are formed, The position in the width direction of the substrate 13 is configured to be positionable with respect to the case body 12.

また、電子部品32は、例えばコンデンサ、抵抗器、インダクタ、トランジスタ、あるいはICなどであり、基板本体31上に形成された図示しないパターンなどとともに、所定の回路、ここでは図示しない放電灯を点灯させるインバータを備えた点灯回路を、基板本体31上に形成している。なお、各図において、電子部品32、33a、33bは一部のみを記載し、その配置は任意に設定可能である。   Further, the electronic component 32 is, for example, a capacitor, a resistor, an inductor, a transistor, or an IC, and lights a predetermined circuit, not shown here, with a pattern (not shown) formed on the substrate body 31. A lighting circuit including an inverter is formed on the substrate body 31. In each figure, only a part of the electronic components 32, 33a, and 33b is described, and the arrangement thereof can be arbitrarily set.

この電子部品のうち基板13の一主面に対して最も上側(第1空間部25側)に突出した電子部品33aの頂部にはシート材としての合成樹脂製の絶縁テープ34が貼着されている。そして、絶縁テープ34の一端は、突出電子部品33aに隣接する2番目に突出高さの大きい電子部品33bの下方部位に貼着され、絶縁テープ34の他端は、突出電子部品33aの電子部品33bとは反対側の下方部位に貼着されている。本実施形態においては、突出電子部品33aおよび隣接する2番目に突出高さの大きい電子部品33bはいずれもインダクタ部品である。絶縁テープ34は、2つの電子部品33a、33bよりもやや幅広な寸法を有しており、これら2つの電子部品33a、33bを包み込むように貼着している。そして、絶縁テープ34の内面側(粘着層側)には、2つの電子部品33a、33bの外表面との間に隙間が形成されている。   An insulating tape 34 made of synthetic resin as a sheet material is attached to the top of the electronic component 33a that protrudes to the uppermost side (the first space portion 25 side) of the main surface of the substrate 13 among the electronic components. Yes. One end of the insulating tape 34 is attached to a lower part of the second largest protruding electronic component 33b adjacent to the protruding electronic component 33a, and the other end of the insulating tape 34 is the electronic component of the protruding electronic component 33a. It is stuck on the lower part opposite to 33b. In the present embodiment, the protruding electronic component 33a and the adjacent second electronic component 33b having the second largest protruding height are inductor components. The insulating tape 34 has a slightly wider dimension than the two electronic components 33a and 33b, and is attached so as to enclose the two electronic components 33a and 33b. A gap is formed on the inner surface side (adhesive layer side) of the insulating tape 34 between the outer surfaces of the two electronic components 33a and 33b.

次に、上記第1の実施の形態の放電灯点灯装置11の製造方法を説明する。なお、図4においては、説明の便宜上、端子台51を省略している。   Next, a method for manufacturing the discharge lamp lighting device 11 according to the first embodiment will be described. In FIG. 4, the terminal block 51 is omitted for convenience of explanation.

まず、図4(a)に示すように、開口部22にパッキン17と蓋部19とを固定して開口部22を閉塞したケース本体15を、開口部21を上側とした状態で保持し、各電子部品32を実装した基板13の基板本体31の両側部をケース本体15の溝部23,23に嵌合させ、ケース本体15の軸方向へと摺動させて挿入することで、基板13をケース本体15内に軸方向に沿って収納する。   First, as shown in FIG. 4 (a), the case body 15 in which the packing 17 and the lid 19 are fixed to the opening 22 and the opening 22 is closed is held with the opening 21 facing upward, The both sides of the board body 31 of the board 13 on which each electronic component 32 is mounted are fitted in the grooves 23 and 23 of the case body 15, and the board 13 is inserted by sliding in the axial direction of the case body 15. The case body 15 is stored along the axial direction.

このとき、スペーサ42の先端がパッキン17に接触することで、基板本体31の端部とパッキン17との間に連通部が形成されるとともに、ケース本体15の内部において、基板本体31の表面側に第1空間部25が、裏面側に第2空間部26が、それぞれ区画される。   At this time, the leading end of the spacer 42 is in contact with the packing 17, so that a communication portion is formed between the end of the substrate body 31 and the packing 17, and the inside of the case body 15 is on the surface side of the substrate body 31. The first space 25 is partitioned into the second space 26 and the second space 26 is partitioned into the rear surface.

この状態で、図4(b)に示すように、ここでは開口部21からノズルNなどにより合成樹脂Pを第1空間部25へと注入すると、この第1空間部25へと流れ込んだ合成樹脂Pの一部が、基板13とケース体12の内面との隙間、あるいは、基板13下方端部側の連通部などを介して第2空間部26へと回り込む。   In this state, as shown in FIG. 4B, here, when the synthetic resin P is injected into the first space portion 25 from the opening 21 by the nozzle N or the like, the synthetic resin that has flowed into the first space portion 25 is obtained. Part of P goes around to the second space portion 26 through a gap between the substrate 13 and the inner surface of the case body 12 or a communication portion on the lower end side of the substrate 13.

なお、合成樹脂Pを第2空間部26へと注入した場合でも、同様の作用により合成樹脂Pが第1空間部25へと回り込む。   Even when the synthetic resin P is injected into the second space portion 26, the synthetic resin P wraps around the first space portion 25 by the same action.

さらに、図4(c)に示すように、合成樹脂Pが所定量、ここでは合成樹脂Pの液面がケース本体15の高さ寸法の半分程度の位置まで充填されると、パッキン16および蓋部18により開口部21を覆い、これらパッキン16および蓋部18をケース本体15に固定する。このとき、基板13から導出されたリード線を蓋部18の図示しない挿通孔を介して端子台51に接続する。   Further, as shown in FIG. 4 (c), when the synthetic resin P is filled to a predetermined amount, here, the liquid surface of the synthetic resin P is filled to a position about half the height of the case body 15, the packing 16 and the lid The opening portion 21 is covered with the portion 18, and the packing 16 and the lid portion 18 are fixed to the case body 15. At this time, the lead wire led out from the substrate 13 is connected to the terminal block 51 through an insertion hole (not shown) of the lid portion 18.

次いで、この状態で、図4(d)に示すように、ケース体12を、開口部21,22が水平方向に向くように、換言すれば、基板13の面方向が上下方向、ここで基板13の一主面側の第1空間部25が上側、第2空間部26が下側となるように倒す。   Next, in this state, as shown in FIG. 4 (d), the case body 12 is arranged so that the openings 21 and 22 face in the horizontal direction, in other words, the surface direction of the substrate 13 is the vertical direction. The first space portion 25 on one main surface side of 13 is tilted so that the second space portion 26 is on the lower side and the second space portion 26 is on the lower side.

このとき、液状の合成樹脂Pは、自重により下側の第2空間部26の全てを充填するように流動し、基板13が合成樹脂Pに埋没する。そして、合成樹脂Pの流動によって合成樹脂Pの液面が、突出電子部品33aの頂部と略同位置で、他の電子部品32、33bの全体を埋没させる高さ位置となり、液面とケース本体15の内面との間に空間が形成される。   At this time, the liquid synthetic resin P flows so as to fill all of the lower second space 26 by its own weight, and the substrate 13 is buried in the synthetic resin P. Then, due to the flow of the synthetic resin P, the liquid level of the synthetic resin P is substantially at the same position as the top of the protruding electronic component 33a and is at a height position where the entire other electronic components 32 and 33b are buried. A space is formed between the inner surface of 15.

また、突出電子部品33aの頂部近傍では、絶縁テープ34の内面側と電子部品33aの外表面との間に形成された隙間内に合成樹脂Pが侵入する。このとき、合成樹脂Pの液面が突出電子部品33aの頂部よりも若干下側の位置となった場合であっても、絶縁テープ34の内面側の隙間内に侵入した合成樹脂Pはその粘性または表面張力の作用によって隙間内にとどまり、この液面から突出した絶縁テープ34に向かって円弧面状となるように液面が湾曲した状態を維持して突出電子部品33aの外表面に充填材に合成樹脂Pを覆うことができる。   Further, in the vicinity of the top portion of the protruding electronic component 33a, the synthetic resin P enters a gap formed between the inner surface side of the insulating tape 34 and the outer surface of the electronic component 33a. At this time, even if the liquid level of the synthetic resin P is slightly below the top of the protruding electronic component 33a, the synthetic resin P that has entered the gap on the inner surface side of the insulating tape 34 has its viscosity. Alternatively, the surface tension stays in the gap due to the action of the surface tension, and the liquid surface is curved so as to form an arcuate surface toward the insulating tape 34 protruding from the liquid surface, and the filler is applied to the outer surface of the protruding electronic component 33a. The synthetic resin P can be covered.

そして、この状態で、図4(e)に示すように、ケース体12を所定温度、例えば80℃下で所定時間、例えば1時間熱処理することで合成樹脂Pを硬化させて、放電灯点灯装置11を完成する。   In this state, as shown in FIG. 4E, the synthetic resin P is cured by heat-treating the case body 12 at a predetermined temperature, for example, 80 ° C., for a predetermined time, for example, 1 hour. Complete 11

この後、基板13から導出された内部リード線35により、端子台51を介して外部から入力された電力を高周波交流電力に変換する点灯回路の出力により放電灯が点灯される。   Thereafter, the discharge lamp is lit by the output of the lighting circuit that converts the electric power input from the outside via the terminal block 51 into the high-frequency AC power by the internal lead wire 35 led out from the substrate 13.

このように、合成樹脂Pの使用量を抑制しつつ基板13を確実に合成樹脂Pに埋没させることができるため、製造性が向上するとともに、電子部品32などの発熱を合成樹脂Pにより確実に放熱でき、電子部品32などの絶縁性を確保でき、かつ、外部からの水気の侵入などをも防止できるなど、信頼性を向上できる。   As described above, since the substrate 13 can be surely embedded in the synthetic resin P while suppressing the amount of the synthetic resin P used, the productivity is improved and the heat generated by the electronic component 32 and the like is reliably ensured by the synthetic resin P. The heat can be dissipated, the insulation of the electronic component 32 and the like can be secured, and the reliability of the device can be improved, such as the prevention of water from entering from the outside.

また、ケース体12を倒す際に、ケース体12の内面との距離が近い側の基板13の主面、すなわち裏面側を下側とすることで、より少ない合成樹脂Pの使用量で基板13の両主面を確実に埋没させることができる。   Further, when the case body 12 is tilted, the main surface of the substrate 13 on the side closer to the inner surface of the case body 12, that is, the back surface side is the lower side, so that the substrate 13 can be used with a smaller amount of synthetic resin P. Both main surfaces can be reliably buried.

さらに、合成樹脂Pの使用量を抑制できるため、製造時に開口部21を上側に向けた状態でケース体12に振動が加わった場合でも、合成樹脂Pがケース体12からこぼれることも防止できる。   Furthermore, since the amount of the synthetic resin P used can be suppressed, it is possible to prevent the synthetic resin P from spilling out of the case body 12 even when vibration is applied to the case body 12 with the opening 21 facing upward during manufacture.

そして、注入する合成樹脂Pの量を調整することで、使用量を抑制しつつ基板13の両主面だけでなく電子部品32をも確実に埋没させることができる。   Then, by adjusting the amount of the synthetic resin P to be injected, not only both main surfaces of the substrate 13 but also the electronic component 32 can be surely buried while suppressing the amount used.

また、電子部品32として耐熱性部品を用いれば、電子部品32を合成樹脂Pに完全に埋没させなくてもよいから、合成樹脂Pの使用量を、より抑制できる。   Further, if a heat-resistant component is used as the electronic component 32, it is not necessary to completely embed the electronic component 32 in the synthetic resin P. Therefore, the usage amount of the synthetic resin P can be further suppressed.

さらに、放電灯を点灯させるインバータ点灯回路などの点灯回路部品としての電子部品32を実装した基板13をケース体12に収納して、このケース体12内にて基板13を合成樹脂Pに確実に埋没させた放電灯点灯装置11を構成することができ、放電灯点灯装置11の放熱性および絶縁性を確保して、信頼性を向上できる。   Further, the substrate 13 on which the electronic component 32 as a lighting circuit component such as an inverter lighting circuit for lighting the discharge lamp is mounted is accommodated in the case body 12, and the substrate 13 is securely attached to the synthetic resin P in the case body 12. The buried discharge lamp lighting device 11 can be configured, and the heat dissipation and insulation of the discharge lamp lighting device 11 can be ensured to improve the reliability.

次に、本発明の第2の実施形態を図5を参照して説明する。なお。図5において図1ないし図4と同一の構成については同一の符号を付してその詳細な説明を省略する。   Next, a second embodiment of the present invention will be described with reference to FIG. Note that. 5, the same components as those in FIGS. 1 to 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

図5は、本発明の第2の実施の形態を示す電気機器の蓋部18の要部拡大図である。図5(a)はねじS1を取付ける前の状態を示す正面図、図5(b)はねじS1を取付けた状態を示す正面図、図5(c)はねじS1を締め付ける前の状態を示す側面図、図5(d)はねじS1を締め付けた状態を示す側面図である。この電気機器のケース体12の側縁部である4つの角部には、ねじ溝43が押し出し成型によって形成されている。蓋部18のねじ溝43に対向する部位にはねじ挿通孔が設けられている。このねじ溝43には蓋部18が開口部21を閉塞した状態でパッキン16を突き破ってねじS1が螺着される。蓋部18のパッキン16側の面からは、ねじ挿通孔を囲むような突条44がパッキン側に突設されている。この蓋部18の突条44は、蓋部18を開口部21に取付けたときにパッキン16をねじ挿通孔の周囲に沿って押圧するので、パッキン16の液密性能を向上させることができ、蓋部18と開口部21との封止性能を向上させることができる。   FIG. 5 is an enlarged view of a main part of the lid portion 18 of the electric apparatus showing the second embodiment of the present invention. 5A is a front view showing a state before the screw S1 is attached, FIG. 5B is a front view showing a state where the screw S1 is attached, and FIG. 5C shows a state before the screw S1 is tightened. FIG. 5D is a side view showing a state in which the screw S1 is tightened. Thread grooves 43 are formed by extrusion molding at four corners which are side edges of the case body 12 of the electrical device. A screw insertion hole is provided in a portion of the lid portion 18 facing the screw groove 43. The screw S1 is screwed into the screw groove 43 through the packing 16 with the lid 18 closing the opening 21. From the surface of the lid portion 18 on the packing 16 side, a protrusion 44 is provided on the packing side so as to surround the screw insertion hole. Since the protrusion 44 of the lid 18 presses the packing 16 along the periphery of the screw insertion hole when the lid 18 is attached to the opening 21, the liquid tightness of the packing 16 can be improved. The sealing performance between the lid 18 and the opening 21 can be improved.

次に、本発明の第3の実施形態を図6を参照して説明する。なお。図6において図1ないし図4と同一の構成については同一の符号を付してその詳細な説明を省略する。   Next, a third embodiment of the present invention will be described with reference to FIG. Note that. 6, the same components as those in FIGS. 1 to 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

図6は、本発明の第3の実施の形態を示す電気機器を示す分解正面図である。なお、図6においては、説明の便宜上、端子台51を省略している。本実施形態では、蓋部18のねじ挿通孔28、29の形状に特徴を有している。蓋体18の上部側に設けられたねじ挿通孔28、28は上方に開放した切欠き形状をなしている。   FIG. 6 is an exploded front view showing an electrical apparatus according to the third embodiment of the present invention. In FIG. 6, the terminal block 51 is omitted for convenience of explanation. This embodiment is characterized by the shape of the screw insertion holes 28 and 29 of the lid portion 18. The screw insertion holes 28 and 28 provided on the upper side of the lid 18 have a notch shape opened upward.

まず、ケース本体の上部側のねじ溝43には、予めねじS1、S1を約半分の締め付け量で螺着しておく。そして、蓋体18を開口部21に沿って図面の矢印方向に移動させ、切欠き状のねじ挿通孔28、28がねじS1、S1に当接する位置までスライドさせる。これによって、蓋体18の装着時の位置決めおよびガイドが容易に行われる。この後、下側のねじ挿通孔29、29とともにねじS1、S1を締め付けることで蓋体18の取り付けが完了する。   First, screws S1 and S1 are screwed into the screw groove 43 on the upper side of the case body in advance with a tightening amount of about half. Then, the lid 18 is moved along the opening 21 in the direction of the arrow in the drawing, and is slid to a position where the notched screw insertion holes 28 and 28 are in contact with the screws S1 and S1. This facilitates positioning and guiding when the lid 18 is mounted. Thereafter, the screws S1 and S1 are tightened together with the lower screw insertion holes 29 and 29, whereby the attachment of the lid 18 is completed.

なお、上記各実施の形態において、ケース体12に注入する充填材は、液状で絶縁性および放熱性などを有するものであれば、上記合成樹脂Pに限定されるものではない。   In each of the above embodiments, the filler injected into the case body 12 is not limited to the synthetic resin P as long as it is liquid and has insulating properties and heat dissipation properties.

そして、電気機器は、放電灯を点灯させる点灯回路部品を用いた放電灯点灯装置に限らず、その他の電力変換装置や、別の電気機器などにも適用することもでき、同様の作用効果が得られる。   The electrical equipment is not limited to a discharge lamp lighting device using a lighting circuit component for lighting a discharge lamp, but can also be applied to other power conversion devices, other electrical equipment, and the like. can get.
