Document Type and Number:
WIPO Patent Application WO/2024/078421
Kind Code:
A1
Abstract:
A relay, comprising: a contact container (10), which has a contact chamber (101); a pair of stationary contact lead-out ends (20), which are connected to the contact container (10); a first magnetic conductor (40), which is fixedly arranged; a pushing rod assembly (50); a movable contact assembly (53); and a third magnetic conductor (60). The pushing rod assembly (50) comprises a rod portion (51), and a supporting seat (52) arranged at one end of the rod portion (51), wherein the supporting seat (52) at least partially extends into the contact chamber (101); and the movable contact assembly (53) comprises a movable contact spring (54) and a second magnetic conductor (55), wherein the second magnetic conductor (55) is fixed at the side of the movable contact spring (54) away from the first magnetic conductor (40). The third magnetic conductor (60) is connected to the supporting seat (52) and is movably arranged in the contact chamber (101). In the process of breaking the movable contact spring (54) from the stationary contact lead-out ends (20), the third magnetic conductor (60) moves preferentially over the second magnetic conductor (55). The relay improves breaking performance and short-circuit resistance.
