Electrical contact terminal having elasticity and mounting structure thereof

An electrical contact terminal having elasticity and configured to mount to a through-hole of a substrate for electrically connecting to a conductive pattern disposed adjacent to the through-hole of the substrate, the electrical contact terminal comprising:

• a core having elasticity and heat resistance and provided with an electrically conductive layer on the outermost surface thereof,
• wherein the core comprises:
• a body part having a first width;
• an insertion part having a second width with a dimension less than that of the first width and extending vertically downward from the body part;
• and
• a contact part in the form of a pair of wings protruding from a distal end of the insertion part in a width direction, wherein the body part, the insertion part, and the contact part are provided as a single body, and the electrically conductive layer is disposed on a bottom surface of the body part, the insertion part, and the contact part to electrically connect the body part, the insertion part, and the contact part to each other,
• wherein a through-hole is defined in the substrate, and first and second conductive patterns are disposed adjacent to the through-hole on a top surface and a bottom surface of the substrate, respectively;
• and
• the insertion part of the electrical contact terminal is fitted into the through-hole so that the body part is electrically connected to the first conductive pattern, and the contact part is electrically connected to the second conductive pattern by elastic restoration force.
