Document Type and Number:
WIPO Patent Application WO/2024/078418
Kind Code:
A1
Abstract:
A relay comprising a contact container (1), a contact assembly (2) and an anti-short circuit assembly (3), wherein the contact container (1) comprises an insulating cover (11); the contact assembly (2) comprises a movable elastic piece (22) and a pair of static contact lead-out ends (21), the static contact lead-out ends (21) at least partially extending into the insulating cover (11), and the movable elastic piece (22) being arranged in the insulating cover (11); the anti-short circuit assembly (3) comprises an upper magnetically conductive magnet (31) and a lower magnetically conductive magnet (32), and a magnetically conductive loop can be formed between the upper magnetically conductive magnet (31) and the lower magnetically conductive magnet (32), such that when the movable elastic piece (22) experiences a large fault current, an attraction force is generated and is used for resisting an electric repulsive force between the movable elastic piece (22) and the static contact lead-out ends (21); the upper magnetically conductive magnet (31) is provided with a fixed mounting foot (311) fixedly connected to the inner wall of the top of the insulating cover (11), such that a gap (312) is provided between the upper magnetically conductive magnet (31) and the inner wall of the top of the insulating cover (11).
