Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a circuit breaker port structure. Background Art

[0002] A circuit breaker is a switch device that can close, carry and disconnect current under normal circuit conditions and close, carry and disconnect current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague, and those above 3kV are generally called high-voltage electrical appliances.

[0003] The existing authorization announcement number is CN216957926U, which discloses a circuit breaker port structure, including a circuit breaker and a port, and also includes a dust blocking mechanism and a bottom protection mechanism. The dust blocking mechanism is composed of a cover box, a rubber partition plate, a square hole, a through hole, an I-shaped rubber hose and a transparent plate. The circuit breaker surface outside the port is fixedly connected with the cover box, and the cover box on one side of the port is bonded with a rubber partition plate. The surface of the rubber partition plate is provided with a square hole, and the surface of the cover box on one side of the square hole is provided with a through hole. The dust blocking mechanism is arranged on the circuit breaker surface outside the port.

[0004] The above device can be inserted into the port through the I-shaped hose at the through hole on the surface of the cover box through the external power cord, and then inserted into the port after passing through the square hole on the surface of the rubber partition board. The internal wiring connection status of the cover box can be observed with the help of a transparent plate. Although the multi-layer barrier of the cover box and the rubber partition board can effectively prevent dust or rain from entering the port, since the circuit breaker is mainly used to protect the circuit from electrical equipment that causes short circuit due to excessive current, it should be in a resettable state under normal circumstances, that is, after being triggered, the user can reset it by manual operation to re-energize the circuit. The above device does not have such a structure. For this reason, we propose a circuit breaker port structure. Utility Model Content
