Title:
CONTACT STRUCTURE, METHOD OF MANUFACTURING CONTACT STRUCTURE AND ELECTROMAGNETIC RELAY
Document Type and Number:
Japanese Patent JP2017191759
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a contact structure, a contact structure manufacturing method and an electromagnetic relay that can further improve thermal conductivity from a contact portion to a conductive plate.SOLUTION: A contact structure 1a further includes a fillet portion 4 formed across a first surface 21 of a conductive plate 2 and a side surface 313 of a contact portion 31. The height of the fillet portion 4 from the first surface 21 gradually decreases as it goes away from the contact portion 31. The surface 411 of the outer peripheral portion 41 of the fillet portion 4 which is spaced apart from the contact portion 31 when viewed from the thickness direction of the conductive plate 2 is inclined with respect to the first surface 21 and formed of a part of the conductive plate 2 so that no step occurs between the fillet portion 4 and the first surface 21 in the direction away from the contact portion 31 along the first surface 21 of the conductive plate 2.SELECTED DRAWING: Figure 1
