底の孔を塞ぎ組立てゝいる。 As shown in Figures 1 and 2, the oil-filled ignition coil is made by fitting the primary coil 1 onto the outer periphery of the secondary coil 2 and inserting the iron core 3 into the inner periphery of the bobbin of the secondary coil. The coil can be stored vertically on the bottom of the case 4 (Fig. 1), or the primary coil 1 can be inserted into the inner periphery of the bobbin of the secondary coil 2, and the iron core 3 can be inserted into the inner periphery of the bobbin of the primary coil. - The core assembly is housed horizontally on the bottom of case 4 with its top open (Fig. 2), and a packing 6 is placed on top of step 5 formed by extending outward from the top of case 4. Place the flange 7' that protrudes from around the cap 7 formed of electrically insulating material on the top, swage the upper edge 4' of the case onto the flange 7' to secure the cap to the case, and then attach the secondary cap provided on the cap. Tower part 8 for terminal installation
After injecting and filling the case with insulating oil 9 through the hole at the bottom of the case, the secondary terminal 10 is installed inside the tower section 8 and the hole at the bottom is closed to assemble.

鉄心組立体がケース内で移動したり、シールが不
充分で絶縁油が漏出したりする虞れがあり、かと
言つてかしめ強度が過大であるとパツキンやキヤ
ツプが破損する虞がある。 The purpose of placing the cap flange 7' on the packing 6 and fixing the upper edge of the case 4 on this flange 7' by caulking is to attach the coil-core assembly to the case using the downward protrusion 11 provided on the cap. To prevent the coil-core assembly from moving within the case by pressing it against the bottom, and to compress the gasket 6 to seal between the cap and the case to prevent leakage of the insulating oil filled in the case. It is. Therefore, if the caulking strength to secure the cap and case is insufficient, the coil
There is a risk that the core assembly may move within the case, or that insulating oil may leak due to insufficient sealing.On the other hand, if the caulking strength is excessive, there is a risk that the packing or cap may be damaged.
要するにかしめ強度はキヤツプ、パツキン、ケ
ースなどの材質、寸法に応じて適切にすべきであ
るが、従来の構造では不安定にならざるを得なか
つた。 In short, the caulking strength should be appropriate depending on the material and dimensions of the cap, packing, case, etc., but conventional structures were inevitably unstable.
そこで本考案はケースの上部にキヤツプの鍔を
受止める上段部と、パツキンをその上に敷く下段

問題点を解消したのである。 Therefore, the present invention has an upper part that receives the cap flange at the top of the case, and a lower part on which the packing is placed. Set the appropriate value, hold the cap's flange on the upper part, and swage the upper edge of the case onto the flange to maintain a constant crimping strength. By compressing it to a predetermined constant state, the problems of the conventional method were solved.

適切に選ぶ。尚、下段部５ｂの内形はパツキンの
外形より僅かに大である。 FIGS. 3 and 4 are partially enlarged sectional views of the case and cap in an uncrimped state and a sectional view of the packing, showing the main parts of the present invention, and FIG. 5 is a partially enlarged sectional view in a crimped state. Case 4, Patsukin 6,
The cap 7 may accommodate the coil-core assembly vertically (FIG. 1) or horizontally (FIG. 2). In accordance with the present invention, the upper part of the case 4 is provided with an upper part 5a on which the cap flange 7' is placed, and a lower part 5b on which the packing 6 is placed.The height t of the lower part 5b is equal to the thickness of the packing 6. is smaller than T, and the ratio T/t>
1 is appropriately selected mainly depending on the material of the packing and the desired degree of compression. Note that the inner shape of the lower step portion 5b is slightly larger than the outer shape of the packing.
これにより下段部５ｂ上にパツキン６を敷き、
その上にキヤツプの鍔７′を載せてケースの上縁
部を鍔上にかしめ、鍔７′の下面が上段部５ａの
段面に当接してかしめに対する抗力が飛躍的に高
まつた時点でかしめを停止すれば、パツキン６は
鍔の下面と下段部５ｂの段面間で一定の所望の圧
縮度に圧縮される。 As a result, the packing 6 is laid on the lower part 5b,
Place the cap's flange 7' on top of it and caulk the upper edge of the case onto the flange.At the point when the lower surface of the flange 7' comes into contact with the stepped surface of the upper part 5a, the resistance against caulking increases dramatically. When the caulking is stopped, the packing 6 is compressed to a constant desired degree of compression between the lower surface of the collar and the stepped surface of the lower step portion 5b.
従つて、製品のかしめ強度、パツキンの圧縮度
は均一で、過不足がなく、コイル−鉄心体のケー
ス内での移動、絶縁油の洩れ、パツキンやキヤツ
プの破損等が起る余地は無くなる。 Therefore, the caulking strength of the product and the degree of compression of the packing are uniform, with no excess or deficiency, and there is no room for movement of the coil-iron core within the case, leakage of insulating oil, damage to the packing or cap, etc.
こうして本考案によれば従来の不安定であつた
かしめ強度とパツキンの圧縮度を所望の一定に保
