Abstract
A push-type solid-state circuit breaker, including: a closing button; an opening button; a locking member; a movable contact capable of moving together with the closing button; a linkage plate, arranged on the housing via a spring and capable of moving in a second direction between an extended position and a recovery position, the linkage plate is in the extended position upon the closing button being in the initial closing position and in the recovery position upon the closing button being in the closed position, upon the linkage plate being in the recovery position and the opening button being in the open position, a part of the linkage plate abuts against the opening button and prevents the opening button from returning from the open position to the initial opening position.
Claims19
A solid-state circuit breaker, comprising:
- a closing button configured to move in a first direction between an initial closing position and a closed position;
- an opening button configured to move in the first direction between an initial opening position and an open position;
- and
- a movable contact, connected to the closing button and capable of moving together with the closing button, so as to separate and contact with a stationary contact;
- a linkage plate configured to move in a second direction between an extended position and a recovery position, wherein the linkage plate is in the extended position upon the closing button being in the initial closing position and in the recovery position upon the closing button being in the closed position,
- upon the linkage plate being in the recovery position and the opening button being in the open position, a part of the linkage plate abuts against the opening button and prevents the opening button from returning from the open position to the initial opening position, only upon the closing button returning from the closed position to the initial closing position and the linkage plate moving from the recovery position to the extended position, the linkage plate allows the opening button to return from the open position to the initial opening position;
- and
- a locking member configured to move in a second direction perpendicular to the first direction between a locked position and an unlocked position, the locking member is biased toward the locked position, in the locked position, the locking member is configured to lock the closing button in the closed position, and upon the opening button being in the open position, the opening button can drive the locking member from the locked position to the unlocked position, so as to release locking of the closing button,
- upon the closing button being in the initial closing position, the movable contact is separated from the stationary contact, upon the closing button moving from the initial closing position to the closed position, the closing button is able to overcome bias of the locking member to allow the movable contact to move toward the stationary contact, upon the movable contact being in contact with the stationary contact, the locking member returns to the locked position and keeps the closing button in the closed position.

- a closing button configured to move in a first direction between an initial closing position and a closed position;
- an opening button configured to move in the first direction between an initial opening position and an open position;
- and
- a movable contact, connected to the closing button and capable of moving together with the closing button, so as to separate and contact with a stationary contact;
- a linkage plate configured to move in a second direction between an extended position and a recovery position, wherein the linkage plate is in the extended position upon the closing button being in the initial closing position and in the recovery position upon the closing button being in the closed position,
- upon the linkage plate being in the recovery position and the opening button being in the open position, a part of the linkage plate abuts against the opening button and prevents the opening button from returning from the open position to the initial opening position, only upon the closing button returning from the closed position to the initial closing position and the linkage plate moving from the recovery position to the extended position, the linkage plate allows the opening button to return from the open position to the initial opening position;
- and
- wherein the linkage plate comprises a main body comprising:
- a first contour notch, formed on the main body, wherein the first contour notch comprises a first contour wall, and a shape of the first contour wall is designed such that, upon the closing button moving between the initial closing position and the closed position, a part of the closing button abuts against the first contour wall of the first contour notch, so that the linkage plate moves between the extended position and the recovery position;
- a second contour notch, formed on the main body, wherein the second contour notch comprises a second contour wall, and a shape of the second contour wall is designed to prevent the opening button from returning to the initial opening position from the open position upon the linkage plate being in the recovery position and the opening button being in the open position;
- the first contour wall and the second contour wall are respectively formed at a side of the first contour notch and the second contour notch away from the spring.
