External circuit breaker of electric energy meter

Abstract

The invention discloses an external circuit breaker of an electric energy meter. The external circuit breaker comprises a shell formed by splicing a plurality of base shells, the plurality of base shells are adjacently spliced to form a plurality of cavities; the shell comprises two convex parts; the plurality of cavities at least comprise a first cavity, a second cavity and a third cavity; a first on-off assembly and a second on-off assembly are respectively arranged in the first cavity and the second cavity; a driving module is arranged in the third cavity; a circuit board is also arranged in the third cavity; a control chip is integrated on the circuit board, a wireless communication module is further welded and fixed to the circuit board, at least one protruding part is provided with an inserting groove used for containing the wireless communication module, the inserting groove is formed by splicing at least two base shells, and the inserting groove is communicated with the third cavity and isolated from the first cavity and the second cavity. According to the invention, the external circuit breaker is compact in structure, convenient to assemble and more stable to use.

Description

technical field [0001] The invention relates to a circuit breaker, in particular to an external circuit breaker with an electric energy meter. Background technique [0002] In order to meet the needs of the Internet of Things, in addition to basic functions such as conventional overcurrent and leakage protection, external circuit breakers for electric energy meters on the market are usually equipped with remote control opening and closing functions. In order to realize remote control of circuit breakers, A circuit breaker generally includes a circuit board integrated with a control chip, a drive module for driving the circuit breaker to open or close, and a wireless communication module to realize remote control signal transmission and reception. The setting of these functional modules takes up a lot of circuit breaker The internal space increases the overall volume of the circuit breaker and also complicates the structure of the circuit breaker. The modules and circuit boar...

[0002] In order to meet the needs of the Internet of Things, in addition to basic functions such as conventional overcurrent and leakage protection, external circuit breakers for electric energy meters on the market are usually equipped with remote control opening and closing functions. In order to realize remote control of circuit breakers, A circuit breaker generally includes a circuit board integrated with a control chip, a drive module for driving the circuit breaker to open or close, and a wireless communication module to realize remote control signal transmission and reception. The setting of these functional modules takes up a lot of circuit breaker The internal space increases the overall volume of the circuit breaker and also complicates the structure of the circuit breaker. The modules and circuit boards are connected by wires, which is prone to interference and is not conducive to assembly, affecting the stable operation of the circuit breaker.
