Description

【考案の詳細な説明】 本考案は高圧電源用モールドケースに関する。[Detailed explanation of the idea] The present invention relates to a molded case for a high voltage power supply.

例えばテレビジョン受像機の高圧電源は防塵、防湿、安
全性等を考慮してモールドケースに樹脂モールドされて
いる。
For example, the high-voltage power supply of a television receiver is molded in a resin molded case in consideration of dust-proofing, moisture-proofing, safety, and the like.

しかしながら、従来のモールドケースではケース内に樹
脂を注入し、硬化させたときにケース内壁からモールド
樹脂がはがれることがしばしばあり、その部分から湿気
等が浸入して絶縁不良を起す欠点があった。
However, in conventional molded cases, when resin is injected into the case and cured, the molded resin often peels off from the inner wall of the case, and moisture etc. can enter from that part, causing insulation failure.

本考案は上記欠点を除去するためになされたもので、以
下本考案の実施例につき図面を参照して詳細に説明する
The present invention has been made to eliminate the above-mentioned drawbacks, and embodiments of the present invention will be described in detail below with reference to the drawings.

第1図は本考案の一実施例を示すモールドケースの平面
図で、平面はぼ長方形のモールドケース1の対向する1
対の長側壁2,2の内面にそれぞれ2個の突起3をケー

FIG. 1 is a plan view of a molded case showing an embodiment of the present invention.
Two protrusions 3 are formed integrally with the case 1 on the inner surfaces of the pair of long side walls 2, 2, respectively.

突起3は本実施例では各側壁2の内面に2個づつ設けら
れているが、短側壁7,7にも設けても良くケースの大
きさによって適宜変更し得るものであり、最低1個は必
要である。
In this embodiment, two protrusions 3 are provided on the inner surface of each side wall 2, but they may also be provided on the short side walls 7, 7, and may be changed as appropriate depending on the size of the case, and at least one protrusion 3 is provided. is necessary.

突起3は第1図から明らかなように断面円形状でケース
10側壁2との接続部分が狭く形成されると共に、第2
図の側面図に示すように、側壁2に垂直方向に形成され
ている。
As is clear from FIG. 1, the protrusion 3 has a circular cross section and a narrow connection portion with the side wall 2 of the case 10.
As shown in the side view of the figure, it is formed perpendicularly to the side wall 2.

また、ケース1の底面4の内面の4隅近傍には高圧電源
の基板5(第2図)を載置するネジ穴8付の台6がケー
ス1と一体に形成されている。
Furthermore, near the four corners of the inner surface of the bottom surface 4 of the case 1, a stand 6 with screw holes 8 on which a high-voltage power supply board 5 (FIG. 2) is placed is integrally formed with the case 1.

基板5は図示しないネジをネジ穴8に螺合することによ
りケース1に固定されている。
The board 5 is fixed to the case 1 by screwing not shown screws into the screw holes 8.

このように構成すると、第2図に示すように基板5(高

に収納したときに、ケース底面4と基板5との間に台6
により空間ができ、従ってこの状態で樹脂を注入すると
、この樹脂が基板5の裏側の空間に回り込むことになる
With this configuration, as shown in FIG.
When stored in the case, there is a stand 6 between the case bottom 4 and the board 5.
A space is created by this, and therefore, if resin is injected in this state, this resin will flow around into the space on the back side of the substrate 5.

また、突起3はケース1との接続部分が細く形成されて
いるから、ケース1内に注入されたモールド樹脂が硬化
したとき、突起3の側壁2との接続部分に引掛り側壁内
面に密着し、はがれが生じない。
In addition, since the protrusion 3 has a narrow connection part with the case 1, when the mold resin injected into the case 1 hardens, it will catch on the connection part of the protrusion 3 with the side wall 2 and adhere tightly to the inner surface of the side wall. , no peeling occurs.

本考案者の実験によれば、第1図、第2図に示す構成の
ケースを使用した結果、モールド樹脂のはがれは1つも
生じなかった。
According to experiments conducted by the present inventor, no peeling of the mold resin occurred as a result of using the case configured as shown in FIGS. 1 and 2.

上記したように、本考案によればモールドケースの側壁
内面に突起を設けたためにモールド樹脂のはがれが完全
に防止される。
As described above, according to the present invention, since the protrusion is provided on the inner surface of the side wall of the mold case, peeling of the mold resin is completely prevented.

また底面内面の台6により形成された基板5との空間に
モールド樹脂が回り込むために、絶縁が良くなり、かつ
半田付は部分が底面に接触しないので沿面放電も防止で
きる等の大なる利点がある。
In addition, since the mold resin wraps around the space between the board 5 formed by the base 6 on the inner surface of the bottom surface, insulation is improved, and since the soldering part does not touch the bottom surface, creeping discharge can be prevented, which is a great advantage. be.

なお、上記実施例では突起3は断面円形状のものを示し
たが、第3図に示すように断面三角形状のものでもよい
In the above embodiment, the protrusion 3 has a circular cross section, but may have a triangular cross section as shown in FIG.

勿論、ケースとの接続部分がその突起部分より細いもの
であれば形状は問わない。
Of course, the shape does not matter as long as the connecting part with the case is thinner than the protruding part.

また、台6の形状は必要に応じて変更し得るものであり
、要は基板とケース底面との間に空間が形成されればよ
い。
Further, the shape of the stand 6 can be changed as necessary, and it is sufficient that a space is formed between the substrate and the bottom surface of the case.

さらに、テレビジョン受像機に限らず、他の高圧電源装
置のケースにも適用できることはいうまでもない。
Furthermore, it goes without saying that the invention is applicable not only to television receivers but also to cases of other high-voltage power supplies.

その他必要に応じて種々の変更がなし得ることは勿論で
ある。
Of course, various other changes can be made as necessary.
