Title:
RELAY
Document Type and Number:
WIPO Patent Application WO/2024/078424
Kind Code:
A1
Abstract:
Provided in the present disclosure is a relay. The relay comprises a contact assembly (2), a short-circuit resistant assembly (3) and a supporting component (6). The contact assembly (2) comprises a movable contact spring (22), and a pair of stationary contact lead-out ends (21) capable of coming into contact with or being separated from the movable contact spring (22); the short circuit resistant assembly (3) comprises an upper conductive magnet (31) and a lower conductive magnet (32); the supporting component (6) is used for bearing the upper conductive magnet (31); and the lower conductive magnet (32) is fixed at the bottom of the movable contact spring (22), and a magnetic conductive loop can be formed between the upper conductive magnet (31) and the lower conductive magnet (32), such that an attractive force is generated when a large fault current occurs in the movable contact spring (22), so as to resist an electrodynamic repulsion force between the movable contact spring (22) and the stationary contact lead-out ends (21). In the present disclosure, the upper conductive magnet (31) is of a fixed structure which is borne by the supporting component (6), such that the requirement of a holding force can be satisfied without needing a large-size coil, thereby being conducive to making the relay lightweight.
