Abstract

A contact has a flat surface and a side surface that is parallel to the flat surface. At least a part of the side surface is curved so as to swell. At least a part of the contact is able to be elastically deformed in parallel to the flat surface.

First claim

The invention claimed is:

1. A contact comprising:
a flat first side surface having a width that is a first value;
a curved second side surface that is curved when viewed from a direction parallel to the flat first side surface, and that is disposed opposite the flat first side surface; and
an elastic deformation portion that is elongated when viewed from a direction perpendicular to the flat first side surface,
wherein a maximum thickness of the contact measured between the first side surface and the second side surface is a second value,
wherein a ratio of the second value to the first value is equal to or greater than 0.4,
wherein at least a part of the contact is able to be elastically deformed in parallel to the flat first side surface, and
wherein at least part of the curved portion of the second side surface is located at the elastic deformation portion in a cross-section perpendicular to the direction in which the elastic deformation portion is elongated.

2. The contact according to claim 1 , wherein the curved portion of the second side surface is continuously formed along the direction in which the elastic deformation portion is elongated.

3. The contact according to claim 1 , wherein the curved portion of the second side surface constitutes a contact point.

4. A contact device comprising:
a contact housing member; and
the contact according to claim 1 disposed in the contact housing member,
wherein the second side surface of the contact is arranged so as to be in contact with a surface of the contact housing member placed so as to be parallel with the flat first side surface,
and
wherein the second side surface slides while being in contact with the surface of the contact housing member when the contact is elastically deformed.
