AI Technical Summary
Technical Problem
Existing relays are prone to arcing when interrupting large currents, leading to poor interruption.
Method used
An exciter generates gas to drive a punching component to break the moving contact from the side away from the stationary contact. Combined with the thinning design of the moving contact, the reaction force between the punching component and the stationary contact is used to achieve efficient disconnection.
Benefits of technology
It improves the efficiency of relay circuit disconnection, avoids arcing, and enhances safety and reliability.

Abstract
A relay includes a plurality of stationary contacts, a movable contact, and a trip assembly. The movable contact is configured to contact or separate from the stationary contacts. The trip assembly is located on a side of the movable contact facing away from the stationary contacts. The trip assembly includes a trigger and a trip member. The trigger is configured to be activated to generate gas when the movable contact contacts the stationary contacts and a threshold current flows through the movable contact. The gas is configured to drive the trip member to move so that the trip member trips the movable contact from the side of the movable contact facing away from the stationary contacts.
