Title:
CONTACT POINT DEVICE AND ELECTROMAGNETIC RELAY
Document Type and Number:
WIPO Patent Application WO/2018/135084
Kind Code:
A1
Abstract:
This contact point device has first contactors (71), oscillating support parts (73), and second contactors (72). The first contactors surround a central shaft and have an outer side surface (711) that is cylindrically shaped. The oscillating support part supports the first contactor so as to allow the central shaft to oscillate. The second contactor is disposed facing the first contactors. Among the first contactor and the second contactor, one has a plurality of first contact point parts (761) provided so as to surround the central shaft on a plane orthogonal to the central shaft, the other has second contact point parts (762) provided so as to protrude toward the space surrounded by the plurality of first contact point parts. A contact surface (763), which is a curved surface exposed to the space, is formed on the second contact point parts so as to surround the central axis.
