- the cap 230 is used, for example, when the conductor Wa of the electric wire W is made of aluminum or an aluminum alloy and the terminal 210 is made of copper or a copper alloy. It is because there is a possibility that electric corrosion will occur if it adheres, and the material of the cap 230 is set to be the same type (copper or copper alloy) as the material of the terminal 210 so that this does not occur. Also, although aluminum or aluminum alloy terminals can be used for the aluminum electric wires, both the terminals 210 and the cap 230 are made of copper or copper because the copper or copper alloy terminals are advantageous in terms of strength. Made of copper alloy.

After reaching the end 33a, it must finally reach the conductor Wa.

- the structure of the cap in other embodiment is explained in full detail.
- the cap 30 ⁇ / b> B shown in FIG. 4 is chamfered at the outer peripheral side corner of the open end 33 a of the cylindrical peripheral wall 33. If the chamfered portion 36 is formed by chamfering the outer peripheral side corner of the open end 33a to a thickness, and the inner peripheral side corner 36a is formed at an acute angle, the open end 33a of the cap 30B can be more easily connected to the electric wire W. It becomes possible to insert into the gap between the conductor Wa and the covering Wb, and the mounting workability of the cap 30B can be improved.
- the cap 30C shown in FIG. 5 is formed by cutting the open end 33a of the cylindrical peripheral wall 33 of the cap 30C with an inclined surface 37 inclined with respect to the central axis of the cap 30, so that the circumference of the cylindrical peripheral wall 33 of the cap 30C is reduced. A portion 33f in the direction protrudes from the other portion. Accordingly, the conductor Wa of the terminal portion of the electric wire W is placed on the protruding portion 33f of the cylindrical peripheral wall 33 as shown by the arrow D, and the conductor Wa of the electric wire W is easily placed inside the cap 30C while using that portion as a guide. It can be inserted.
- the chamfered portion 36 is provided by chamfering the outer peripheral side corner portion of the opening end 33a of the cylindrical peripheral wall 33 as in the cap 30D shown in FIG. If the side corner portion 36a is formed at an acute angle, the opening end 33a of the cap 30D can be more easily inserted into the gap between the conductor Wa of the electric wire W and the covering Wb.
- a projecting portion 38 that is convex on the outer peripheral side is annularly formed in the vicinity of the opening end 33a of the cylindrical peripheral wall 33 of the cap 30E. If formed, when the opening end 33a of the cap 30E is inserted into the gap between the conductor Wa of the electric wire W and the covering Wb, the protruding portion 38 is caught by the covering Wb, and is difficult to come off. Moreover, since the intrusion route of the moisture S is bent more complicatedly, the invasion of the moisture S can be further prevented. Also in this case, by providing the chamfered portion 36 at the opening end 33a as in the cap 30B of FIG. 4, it is possible to ensure ease of insertion into the gap between the covering Wb and the conductor Wa. Moreover, you may cut the opening end 33a with an inclined surface like the cap 30C of FIG.
