High-voltage DC relay having a movable piece

A high-voltage DC relay, comprising a housing, two main lead-out terminals, a main movable piece and a pushing rod component;

• the two main lead-out terminals are respectively mounted on a top of the housing and bottom ends of the two main lead-out terminals are respectively located inside the housing, the main movable piece is accommodated in the housing and fitted under the two main lead-out terminals, when the main movable piece is pushed by the pushing rod component and then contacts the two main lead-out terminals, current flows in from one of the two main lead-out terminals, and flows out from another of the main lead-out terminals after passing through the main movable piece, so that the main movable piece is bridged with the two main lead-out terminals;
• the main movable piece and the pushing rod component are assembled together to form a movable assembly;
• wherein the relay further comprising two auxiliary lead-out terminals, an auxiliary movable spring and an insulating partition plate;
• the insulating partition plate is disposed in a first vertical plane on a side of the main movable piece, the auxiliary movable spring is disposed on a side of the insulating partition plate opposite the main movable piece, and a main body portion of the auxiliary movable spring is disposed in a second vertical plane, the insulating partition plate is configured to completely isolate the main movable piece and the auxiliary movable spring;
• the auxiliary movable spring is insulated from the movable assembly and fixed to the movable assembly through the insulating partition plate, so as to follow a movement of the movable assembly to achieve bridging with the two auxiliary lead-out terminals;
• the other side of the insulating partition plate is connected with the movable assembly.
