Abstract
An electronic molded case circuit breaker with an easy-to-connect accessory. Mainly solves the problem that the accessory connection of the existing electronic molded case circuit breaker is inconvenient. The method is characterized in that: the circuit board is provided with an accessory interface, the position of the upper cover corresponding to the accessory interface is provided with an interface groove, and the upper cover is also provided with wiring grooves which are transversely arranged and extend towards two sides of the upper cover. The connecting wire of the accessory is directly connected with the accessory interface through the interface groove by opening the top cover when the accessory is connected, and the accessory is more convenient to connect by running the wire along the wiring groove.
Description
Technical Field
The invention relates to an electronic molded case circuit breaker, in particular to an electronic molded case circuit breaker with an accessory convenient to connect.
Background
The circuit breaker is a current switching device for distributing electric energy and protecting a power line, a motor and the like in real time, and can test load, switch on and switch off the current in a normal loop according to the states of normal, overload, short circuit, undervoltage and the like of the circuit, thereby ensuring the safety of the circuit. An electronic molded case circuit breaker is one of the circuit breakers, which uses a plastic insulator as the housing of the device and can also cut off the current after the actual current exceeds the trip setpoint.
In general, the circuit breaker is connected with accessories, and the accessories of the electronic molded case circuit breaker are connected with a circuit board in the electronic molded case circuit breaker through wires, so that connecting wires of the accessories are also usually arranged in a shell of the electronic molded case circuit breaker, but main working elements such as an operating mechanism and a release of the circuit breaker are installed in the shell, and when the accessories are disconnected, the operation is troublesome and difficult.
Disclosure of Invention
In order to overcome the defects of the background technology, the invention provides an electronic molded case circuit breaker with an conveniently connected accessory, which solves the problem that the accessory of the existing electronic molded case circuit breaker is inconvenient to connect.
The invention adopts the technical scheme that: an electronic molded case circuit breaker with convenient connection type accessories comprises a base, an upper cover, a top cover and a circuit board; the circuit board is arranged between the base and the upper cover, and the top cover is arranged on the upper cover; the circuit board is provided with an accessory interface, the position of the upper cover corresponding to the accessory interface is provided with an interface groove, and the upper cover is also provided with wiring grooves which are transversely arranged and extend towards two sides of the upper cover.
The wiring groove is composed of two groups of limiting bosses which are arranged in parallel at intervals, and a notch groove is arranged at the position of the limiting boss corresponding to the interface groove.
And a plurality of 7-shaped limit hooks are also arranged on the wiring groove.
The beneficial effects of the invention are as follows: when the accessory is connected, only the top cover is required to be opened, the connecting wire of the accessory directly penetrates through the interface groove to be connected with the accessory interface, the traveling wire is carried out along the wiring groove, and the accessory connection is more convenient.
