せて接触を図っている。As shown in FIG. 7, the connection of the high-voltage resistance wire to the terminal 5 attached to the terminal is cut to a fixed length for each cylinder number of an automobile engine, and then as shown in FIG. Next, the insulating coating 4 is peeled off at a fixed length from the cut end to expose the conductor 3, and then, as shown in FIG. 9, the exposed conductor 3 is folded back from the end face of the insulating coating 4 along the outer peripheral surface. In this state, the conductor 3 is inserted into the inside of the terminal 5, and the portion of the folded conductor 3 along the outer peripheral surface of the insulating coating is crimped to the inner surface of the bottom of the terminal 5. In the connection structure, as shown in FIGS. 10 and 13, by crimping and crimping the terminal 5, the folded conductor 3 is pressed by the insulating coating 4, and the winding 2 of the conductor 3 is attached to the bottom inner surface of the terminal 5. The contact is made by making close contact.

には導体３と端子５が接触不良を生じる結果となる。However, in the above structure, when the rubber of the insulating coating 4 undergoes thermal deterioration, the rubber elasticity decreases and the volume shrinks, and the load for bringing the conductor 3 into close contact with the inner surface of the terminal 5 becomes insufficient. When vibration is applied thereto, the conductor 3 peels off from the terminal 5, and a spark is generated at the peeled portion, so that the insulating rubber is further deteriorated. The above interaction ultimately results in poor contact between the conductor 3 and the terminal 5.

A technique in which the folded portion 3a along the insulating coating end face of the conductor 3 is brought into contact with and brought into contact with the conductor 3, or a technique in which a conductive paint 6 such as epoxy is applied to the contact portion between the conductor 3 and the terminal 5 as shown in FIG. Provided. In addition, a technique is provided in which both the stopper portion 5a and the application of the conductive paint 6 are used in combination at the plug-side terminal portion, which is particularly susceptible to thermal degradation.

証に限界がある。Normally, the connection between the conductor 3 and the terminal 5 of such a high-voltage resistance wire must be guaranteed for the same level as the life of the engine. However,
Even when the stopper portion 5a and the application of the conductive paint 6 are used together, conduction failure may occur after long-term running. That is, the conventional connection structure described above has a limitation in long-term guarantee.

料６が多量に必要となる問題がある。The limitation in the above connection structure is that the folded conductor 3 is crimped with the maximum load over its entire length and the conductor 3 is made to extend along the outer surface of the insulating coating 4 over its entire length in order to obtain stable contact. This is because the smaller the outer diameter of the wire is, the more difficult it is.
Further, since the applied conductive paint 6 is also stretched at the same time as the pressing, there is a problem that a large amount of the conductive paint 6 is required to obtain stable contact.
