【考案の詳細な説明】
従来この種の装置は第２図に示すようにケース１の内周
壁面は平滑に仕上げられているため、ケース１内に充填
した充填剤１０が硬化するにしたがって、その体積が収
縮するため、ケース内周壁面と充填剤１０との間に隙間
が生じ、これによって充填剤１０のケース１に対する軸
方向の摩擦力が少なく、このため充填剤１０がケース１
から抜は出すおそれがあり、したがって故障を起すおそ
れが多分にあった。[Detailed Description of the Invention] Conventionally, in this type of device, as shown in FIG. 2, the inner circumferential wall surface of the case 1 is finished smooth, so that as the filler 10 filled in the case 1 hardens, As the volume contracts, a gap is created between the case inner circumferential wall surface and the filler 10, and as a result, the frictional force of the filler 10 against the case 1 in the axial direction is small.
There was a risk of the product being pulled out, and therefore there was a high risk of causing a breakdown.
この考案はこのような欠点を解消しようとするもので、
以下図によってこの考案の一実施例を説明する。This idea attempts to eliminate these shortcomings.
An embodiment of this invention will be explained below with reference to the drawings.
すなわち第１図において筒状のケース１の一端にはヘッ
ドキャップ３が嵌挿され、このキャップ内にはコイル４
およびコア５が収容されている。That is, in FIG. 1, a head cap 3 is fitted into one end of a cylindrical case 1, and a coil 4 is inserted into this cap.
and core 5 are accommodated.
またケース１内にはプリント基板６およびこの基板に取
付けた回路部品７，７が収容されている。Further, the case 1 houses a printed circuit board 6 and circuit components 7, 7 attached to this circuit board.
プリント基板６に一端を接続したコード８がケース１外
に引出されている。A cord 8 whose one end is connected to a printed circuit board 6 is drawn out of the case 1.
ケース１の内周壁には多数の凹部９，９が、その軸心と
交差する方向に、たとえば環状あるいはらせん状に形成
されている。A large number of recesses 9, 9 are formed in the inner circumferential wall of the case 1 in a direction intersecting the axis of the recesses, for example, in an annular or spiral shape.
そしてケース１内には充填剤１０たとえばエポキシ樹脂
が充填されている。The case 1 is filled with a filler 10 such as an epoxy resin.
この考案は上述のようにケース１の内周壁に多数の凹部
９，９を、その軸心と交差する方向に設けているのでケ
ース１内に充填した充填剤が硬化することによって収縮
し、ケース１との間に隙間が生じても凹部８９，９と係
合しているため、充填剤１０はケース１の軸方向に抜出
ることはない。As mentioned above, in this device, a large number of recesses 9, 9 are provided in the inner peripheral wall of the case 1 in a direction intersecting the axis of the recesses, so that the filler filled in the case 1 hardens and contracts. Even if there is a gap between the filler 10 and the case 1, the filler 10 will not come out in the axial direction of the case 1 because it is engaged with the recesses 89 and 9.
