Claims

[Claims for Utility Model Registration] 1. In a contact that is press-fitted into a through-hole in a substrate, the cross section of the press-fitted part is a through-hole in which one or two corners of a quadrilateral are taken along the axial direction of the contact. A shape that has play in one direction relative to the through hole, a shape that has play in both directions with respect to the through hole with four corners of the quadrilateral taken, and a shape that has play in both directions with respect to the through hole, and a shape that has play in both directions with respect to the through hole. A shape in which there is play in the opposite direction with respect to the through hole, a shape in which the four corners of the quadrilateral are removed and there is play in both directions with respect to the through hole, and one or two corners of the quadrilateral in one direction. The sections are removed and sequentially formed into a shape with play in one direction with respect to the through hole, and when the press-fit section is inserted into the through hole, one or two corners of the quadrilateral cross section in one direction or in the opposite direction If the shape of the part is removed and there is play in one direction or the opposite direction with respect to the through hole, one or two corners will be bent toward the side where the corner has been removed, and the corner of the press-fit part will be pushed through due to the reaction force. A press fit contact characterized by pressure contact with a hole. 2. In a contact that is press-fitted into a through-hole in a substrate, the cross-section of the press-fitted part is a quadrangle along the axial direction of the contact, and the four corners of the quadrangle are taken so that there is play in both directions with respect to the through-hole. A shape in which one or two corners in one direction of the quadrilateral are removed so that there is play in one direction with respect to the through hole, and a shape in which four corners of the quadrilateral are taken out so that there is play in both directions with respect to the through hole. A certain shape and one or two opposite corners of the quadrangle are removed to form a shape in which there is play in the opposite direction to the through hole, and when the press fit part is inserted into the through hole, the press fit part The quadrangular cross-section portion is pressed against the through hole in both directions, and one or two corners of the quadrangular cross section are taken in one direction or in the opposite direction to allow play in one direction or the opposite direction with respect to the through hole. In a certain shape, one or two corners are bent toward the cut side,
A contact for a press fit, characterized in that a corner of a press fit part is brought into pressure contact with a through hole by a reaction force.
