Title:
CONTACT DEVICE AND ELECTROMAGNETIC RELAY
Document Type and Number:
WIPO Patent Application WO/2019/116837
Kind Code:
A1
Abstract:
The present disclosure addresses the problem of providing a contact device and an electromagnetic relay wherein conduction failure caused by a frozen contact can be prevented. A contact device (A1) according to the present disclosure comprises a fixed terminal (1), a moving member (11), a regulating member (12), and a heat transmission structure (16). The fixed terminal (1) has a fixed contact (13). The moving member (11) has a moving contact (14) and moves between a closed position where the moving contact (14) comes in contact with the fixed contact (13) and an open position where the moving contact (14) is away from the fixed contact (13). The regulating member (12) comes in contact with the moving contact (14) when the moving member (11) is located at the open position. The heat transmission structure (16) transmits heat from the moving contact (14) to the fixed terminal (1) through a thermal path including at least the regulating member (12) when the moving member (11) is located at the open position.
