Abstract

Disclosed is a switchboard. The switchboard includes a switchboard case (110) with a built-in circuit breaker (150), a door (120) mounted on the switchboard case (110) in a hinge structure to be opened or closed and configured to include a door hook (121) including an inclined surface (121a) at a front end, an external manipulation handle (111) provided at an outer side of the switchboard case (110) and configured to manually, externally manipulate a switch-on or off operation of the circuit breaker (150), and a catching member (140) disposed in the switchboard case (110) to be contactable with the inclined surface (121a) of the door hook (121). The catching member (140) rotates by contacting the inclined surface (121a) of the door hook (121) according to a closing operation of the door (120), and a locked state of the door (120) is maintained by catching the door hook (121) on one side corner of the catching member (140).

Description

technical field [0001] The present disclosure relates to a switchboard that allows a user to easily close a door. Background technique [0002] Generally, a molded case circuit breaker (MCCB) is an electrical device that automatically cuts off the circuit when an overload or short circuit occurs in the circuit, thereby protecting the circuit and the load device. When the MCCB is provided in the switchboard, a separate external operating handle device is used in conjunction with the MCCB to manually operate the on / off of the handle of the circuit breaker outside the switchboard. [0003] figure 1 is a front view showing an external handle operator of a prior art switchboard housing. The MCCB is disposed in the switchboard case 1 , and the door 2 is disposed at the switchboard 1 in a hinge structure and closes or opens the front opening of the switchboard case 1 . In addition, a joystick 3 is provided on an outer side of the switchboard case 1 so as to be rotatable in a ver...
