Abstract

The invention discloses a breaker voltage isolation structure, comprising a circuit board, a support, a push plate, a conductive piece and a knob rod. The support is installed on the circuit board, the push plate is installed on the support in a sliding mode, the conductive piece is installed on the push plate and can conduct the circuit board and an external circuit, and the knob rod is installedon the circuit board in a rotating mode and is equipped with a cam. The cam is provided with a top abutting face located at the top end. When the abutting surface of the cam is not in contact with the push plate, the circuit board is not communicated with an external circuit; when the knob rod is rotated, the cam pushes the push plate to slide on the support, and when the cam is rotated until theabutting surface of the cam abuts against the push plate, the conductive part on the push plate moves along with the push plate to conduct the circuit board and an external circuit. The invention provides a breaker voltage isolation structure which can rapidly and accurately disconnect or connect an external circuit and a circuit board, and is good in conduction synchronism and high in use safety.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to a circuit breaker voltage isolation structure. Background technique [0002] With the needs of the country's rapid development, especially national-level construction projects such as smart manufacturing, smart platforms, and new infrastructure have been launched one after another. The current low-voltage circuit breakers tend to develop in the direction of intelligent or electronic. Some low-voltage circuit breakers need to realize real-time measurement of current, voltage, power, frequency and other parameters. Therefore, more or less low-voltage circuit breakers are equipped with circuit board. The operating voltage of the circuit board may be powered from an external circuit, and may also be supplied with signals from an external circuit to the circuit board for calculation and identification during real-time measurement. [0003] Low-voltage circu...
