Abstract
The present disclosure relates to a shutter assembly and a switchboard comprising same, and provides a shutter assembly comprising: a shutter plate arranged to cover an outer terminal arranged on the rear surface of a switchboard case; and a shutter driving unit which is connected to one side of the shutter plate and which moves the shutter plate in the left and right directions, wherein the shutter driving unit has at least a portion pressed and rotated by means of a circuit breaker according to the entry of the circuit breaker into the switchboard case, so that the outer terminal covered by the shutter plate is exposed toward the inside of the switchboard, and thus the shutter plate is moved.
Claims18
A shutter assembly comprising:
- a shutter plate disposed to cover an external terminal disposed on a rear surface of a switchboard case;
- and
- a shutter driving unit connected to one side of the shutter plate and configured to move the shutter plate in a left-right direction, including:
- a bracket mounted on a side plate of the switchboard case that includes a bracket body mounted on a side surface of the switchboard case, and wherein the bracket body includes:
- an elastic member hook protrusion protruding from a first end of the bracket body and configured to fix a first end of an elastic member;
- and
- a coupling protrusion protruding from a second end of the bracket body opposite to the first end of the bracket body and protruding in a direction opposite to a protruding direction of the elastic member hook protrusion;
- a slider connected to the bracket to be moved relative to the bracket;
- a main body disposed close to a front surface of the switchboard case;
- and
- a first split body and a second split body vertically separated and extending from the main body toward the rear surface of the switchboard case,
- wherein:
- when the slider is moved toward the rear surface or the front surface of the switchboard case by a circuit breaker, the slider moves at least a portion of the shutter plate
- the shutter driving unit is configured so that the shutter plate is moved by at least a portion that is rotated by being pressed by the circuit breaker as the circuit breaker enters the switchboard case so that the external terminal covered by the shutter plate is exposed toward an inside of a switchboard.

A switchboard comprising:
- a switchboard case having a space in which a circuit breaker is accommodated and having a front surface formed with an opening and a rear surface on which an external terminal is disposed;
- a circuit breaker connected to the external terminal and inserted into and withdrawn from the switchboard case;
- and
- a shutter assembly disposed inside the switchboard case and configured to open and close the external terminal as the circuit breaker is inserted and withdrawn,
- wherein the shutter assembly includes:
- a shutter plate disposed to cover the external terminal;
- and
- a shutter driving unit connected to one side of the shutter plate and configured to move the shutter plate in a left-right direction, including:
- a bracket mounted on a side plate of the switchboard case that includes a bracket body mounted on a side surface of the switchboard case, and wherein the bracket body includes:
- an elastic member hook protrusion protruding from a first end of the bracket body and configured to fix a first end of an elastic member;
- and
- a coupling protrusion protruding from a second end of the bracket body opposite to the first end of the bracket body and protruding in a direction opposite to a protruding direction of the elastic member hook protrusion;
- a slider connected to the bracket to be moved relative to the bracket,
- a main body disposed close to a front surface of the switchboard case;
- and
- a first split body and a second split body vertically separated and extending from the main body toward the rear surface of the switchboard case, and
- wherein:
- the shutter driving unit is configured so that the shutter plate is moved by at least a portion that is rotated by being pressed by the circuit breaker as the circuit breaker enters the switchboard case so that the external terminal covered by the shutter plate is exposed toward an inside of a switchboard.
