In addition, in the present embodiment, the edge portion on the side where the cuts 11a and 12a are formed has a step shape, but as shown in the development view of FIG. The two small parallelograms may intersect at different heights, and the cuts 11a and 12a may be formed on the upper side of each. However, by making it stepwise, each press contact blade 11, 1
2 becomes clearer and easier to understand, and it becomes easier to cross the wires. The cut shape formed with the press contact blades 11 and 12 is not particularly limited, and may be appropriately modified depending on the type of core wire such as single wire or multiple wire.
