Problems solved by technology
Because the Internet of Things or smart miniature circuit breaker is an emerging product, there are not many such products in the known field. Even if there are, they generally use extended circuit breaker bodies for the aforementioned problems such as sensors and signal transmission. Dimensions, squeezing the space inside the circuit breaker, the general wiring is chaotic, the electrical isolation does not meet the requirements, the signal crosstalk is very serious, and the wireless signal transmission is unstable, etc.

The invention discloses a miniature circuit breaker operation surface side-embedded signal device. The device comprises a bottom shell and an upper cover, the bottom shell and the upper cover are fixedly connected through mounting holes; a handle is arranged at an upper end of the bottom shell; a left side and a right side of the handle are side end faces of the bottom shell, clamping grooves areformed in the side end faces, pin bases are installed in the clamping grooves, signal transmission devices can be installed in the clamping grooves, pins matched with the pin bases are installed on the signal transmission devices, installation rails are arranged below the bottom shell, and wiring ports are formed in a left side and a right side of the bottom shell. The device is simple and reasonable in structure, the signal transmission devices are arranged on the outer side such that the signal shielding caused by a circuit breaker body, electrical isolation, arc interference, metal pieces and the like is effectively avoided; the device conforms to the size of a miniature circuit breaker marked in the national standard, the pin bases has heat dissipation effects, and meanwhile, the signal transmission devices can be made into a passive jumper wire row to be in basic signal parallel connection with an adjacent circuit breaker.
Description
technical field [0001] The invention relates to a side-embedded signal device on the operation surface of a miniature circuit breaker, which belongs to the technical field of miniature circuit breaker equipment. Background technique [0002] At present, in the field of known low-voltage electrical appliances, miniature circuit breakers are used in infrequent opening and closing lines to protect the overload and short circuit of lines and equipment. In addition, the leakage protection opening is added; some have added external control signal releases, which are used to control openings such as undervoltage and prepaid meters; some have also added motor opening and closing mechanisms controlled by external level signals. [0003] With the development of the Internet of Things, there are new requirements for the functional requirements of miniature circuit breakers. For example, the intelligent processing of data such as line voltage, load current, and line leakage, in order t...
