る。In recent years, in the field of automobiles, high performance and high functionality of vehicles have been rapidly promoted. Therefore, wiring has increased along with the increase of various electric equipments and control equipments to be mounted on the vehicle. Since the weight of the entire copper electric wire is also increasing, it is desired to reduce the weight of the wiring in order to reduce the vehicle weight.

Since it is heavy in itself, there is a strong demand to reduce the weight of the vehicle and make it lighter. Therefore, for the purpose of weight reduction, the specific gravity of copper is about 3
Recently, aluminum electric wire using aluminum, which is one-third of aluminum, as the conductor wire has been particularly attracting attention in the automobile field (8.

However, when the aluminum electric wire is used for automobiles, the following problems occur.

に行われている。Usually, the higher the pressure of the crimp connection or the larger the contact area, the smaller the contact resistance. However, if the contact itself is dirty or the pressure is weak, a non-negligible contact resistance occurs. In this case, since aluminum is very active, the outer surface of the aluminum wire is easily oxidized by peeling off the outer cover of the aluminum wire to expose the conductor wire and exposing the surface to the atmosphere. An oxide film is formed. This oxide film is about 100Å
Although it is extremely thin as shown below, it is usually dense, hard, and insulative, so normally, just before connecting the aluminum wire to the wire terminals, this oxide film is manually machined beforehand using a wire brush etc. It is common practice to destroy and remove it.

Then, the subject which this invention tends to solve is providing the crimp terminal which can be connected, destroying the oxide film of an aluminum electric wire.

By digging into the surface, the oxide film on the surface of the aluminum conductor wire is destroyed and removed. In other words, the oxide film is scraped off by the intrusion of the ridge of the contact part into the conductor,
Or it will be pushed away, which will result in good contact with the conductor. Furthermore, since a sufficient contact load can be obtained by crimping, sealing such a contact site,
Again oxidation is prevented. Also, pulling out of the electric wire is prevented. Therefore, a highly reliable connection with low contact resistance can be obtained.

Although the crimp terminal having the fastening portion is shown in the above embodiment, it is of course possible to adopt a configuration without such a fastening portion, for example, a configuration including a plurality of crimp portions for relay connection or branch connection of electric wires. Further, a plurality of contact portions having ridges may be provided on the inner surface of the crimp portion.
