Description

Technical Field

[0001] The utility model relates to the field of wiring bar bases, in particular to a universal circuit breaker wiring bar base. Background Art

[0002] The terminal block base is also called a drawer base. When the circuit breaker is repaired or otherwise operated, the circuit breaker body can be shaken out of the terminal block base to separate the circuit breaker body from the main circuit of the terminal block base, thereby realizing the power-off operation. In order to improve the operator's safety, a safety partition is usually provided between the circuit breaker body and the main circuit of the terminal block base.

[0003] For example, the Chinese patent publication number CN201781212U discloses a safety device for opening and closing the isolation baffle of a withdrawable circuit breaker, which is installed in the bottom frame of the drawer seat of the circuit breaker, and includes four isolation baffles, a guide plate and two springs. Two of the four isolation baffles are installed on the preset transverse slideway on the upper part of the bottom frame, and the other two are installed on the preset transverse slideway on the lower part of the bottom frame. The guide plate is inserted into the preset slot on the bottom frame; the upper and lower surfaces of the guide plate are respectively provided with two guide rails, and the inner end of the guide plate is provided with two guide rods; the two guide rails above the guide plate are respectively connected with the two isolation baffles installed on the upper part of the bottom frame, and the two guide rails below the guide plate are respectively connected with the two isolation baffles installed on the lower part of the bottom frame. Two springs are respectively mounted on the two guide rods on the guide plate. The utility model has the advantages of compact structure, high safety and reliability of opening and closing the isolation baffle of the circuit breaker drawer seat, high synchronization and stability, and convenient assembly and use.

[0004] Since the isolation baffle has multiple bumps, which are small and thin, the bumps on the isolation baffle are prone to breakage and damage during use, resulting in inability to use normally. Therefore, the isolation baffle needs to be disassembled and replaced. However, the base frame of the drawer seat of the circuit breaker is an integrated structure, which means that when disassembling the isolation baffle, the base frame often needs to be disassembled as a whole, which causes many inconveniences in replacing the isolation baffle, thereby affecting maintenance efficiency.
