できない。Further, a central electrode connected to an ignition coil is in contact with the center of rotation of the rotor electrode, and the discharge electrode is connected to a spark plug. Therefore, when the rotor electrode rotates together with the shaft, a spark is generated between the rotor electrode and the discharge electrode, igniting the spark plug. As stated in Japanese Patent Application Laid-Open No. 53-8693, a brass plate or aluminum plate of 1 to 2 wn was conventionally used for the discharge electrode, but as mentioned above, it was difficult to use it for a long time due to wear due to high voltage discharge. Can not.

。Increasing the plate thickness may be considered as a countermeasure, but if the plate thickness is increased too much, it becomes difficult to perform press processing, and the high voltage withstand resin must be made thicker during molding, resulting in an increase in external dimensions. Problems such as weight and weight may arise.
An object of the present invention is to provide a power distribution cap for an internal combustion engine power distributor that can be extended to about twice the usage period by simple improvement, and is characterized in that the power distribution cap is connected to a spark plug. The conductive plate connected to the side electrode is folded back so as to face the circumferential portion of the rotor electrode that the tip of the central electrode contacts, and the upper half of the folded portion is embedded in a high-voltage resin. There is a particular thing.

としてある。FIG. 1 is a sectional view of a power distribution cap that is an embodiment of the present invention. The power distribution cap 1 has a central electrode 2 connected to an ignition coil, a side electrode 3 connected to a spark plug, integrally molded from high-voltage resin 4, and screwed to a housing 5. A high withstand voltage resin 4 is fixed to the upper end of a shaft 10 passing through the center of the housing 5, and a rectangular rotor electrode 9 is fixed to the upper surface thereof. Further, the lower end of the center electrode 2 is in contact with the center of rotation of the rotor electrode 9, and the peripheral end of the rotor electrode 9 is close to and opposite to the side surface of the discharge electrode 6 connected to the side electrode 3. The discharge electrode 6 is formed by forming a brass plate into an L-shape and bending it twice from the folded part 11 at the tip to form the discharge surface 7.
It is as follows.

高耐電圧樹脂４で埋設してある。第２図は第１図の放電
電極をロータ電極側から見た側面図てある。Further, a hole 12 is provided in the folded portion, and the portion up to this portion is filled with high voltage withstand resin 4. FIG. 2 is a side view of the discharge electrode shown in FIG. 1, viewed from the rotor electrode side.

の期間使用することができる。Notches 13a are formed in order to remove the raised portions of flesh that develop on both sides of the folded portion 11 of the discharge electrode 6, and holes 12 and notches 13b are formed in the portions buried with the high withstand voltage resin 4. This improves the adhesion between the discharge electrode 6 and the high-voltage resin 4. By forming the discharge electrode 6 by folding it back in this way, even if the discharge surface 7 is consumed by discharge, it can be used for about twice as long.

It never falls off. In addition, the above-mentioned notch part 13a
Forming also has the advantage that it becomes easy to set the discharge electrode 6 in the mold. The power distribution cap of this embodiment has a folded part formed at the tip of the discharge electrode 6, and a hole or notch part formed in the folded part.
This has the effect of prolonging the consumption period due to electric discharge, increasing the lifespan, and facilitating the molding operation using high voltage withstand resin.
