That is, the upper contact portion 110 and the lower contact portion 120 both extend straight in the vertical direction and extend in the same line. A predetermined contact structure may be provided on the lower portion of the lower contact portion 120 so as to be in contact with the external electric terminal. For example, the contact structure may be a crown or a pin structure having a predetermined three-dimensional configuration as provided in the upper contact portion 110.

An elastic holding part 130 may be provided between the upper contact part 110 and the lower contact part 120.

The elastic holder 130 may have a U-shaped configuration. In other words, while the upper contact portion 110 and the lower contact portion 120 extend in the vertical direction, the resilient holding portion 130 is bent in a C-shape laterally so that the entire main contact portion 100 is bent in the longitudinal direction And has a shape with a center portion protruding in the right direction. Here, the rightward direction is described with reference to the drawings for the sake of convenience, and the direction may be a different direction when viewed from another viewpoint.

As the elastic holding portion 130 is curved in a C-shape, the elastic holding portion 130 has the first line portion 122 in the upper portion, the second line portion 124 in the middle, and the third Line portion 126, as shown in FIG.

As the upper contact portion 110, the elastic holding portion 130 and the lower contact portion 120 are continuously connected to each other, a bending portion is also formed between the upper contact portion 110 and the first line portion 122, A bent portion is also formed between the lower contact portion 120 and the third line portion 126.

Accordingly, when the name of each bent portion is divided, a first bent portion 141 is formed between the upper contact portion 110 and the first line portion 122, and the first line portion 122 and the second line 122 A second bent portion 142 is formed between the second line portion 124 and the third line portion 126 and a third bent portion 143 is formed between the second line portion 124 and the third line portion 126, A fourth bent portion 144 is formed between the lower contact portion 120 and the lower contact portion 120.
