In recent years, plug-in circuit breakers are more and more widely used, and particularly, with the rapid development of the 5G industry, 5G cabinets have more and more requirements, and plug-in circuit breakers used in cooperation with the 5G cabinets are more and more valued by manufacturers.

Chinese patent application publication No. CN107993900A discloses a plug-in type miniature circuit breaker. The invention is applied to the most common commercial plug-in circuit breaker. The plug-in circuit breaker adopts a button type structure, and when the button is pressed, the circuit breaker is switched on; when the button is pulled out, the breaker is opened. But this structure easily takes place the maloperation problem that the circuit breaker breaks away from the rack when opening. In order to solve the problem, the chinese patent application No. 202010287069.2 provides a switching-on/off handle mechanism of a plug-in circuit breaker, which controls switching-on and switching-off by rotation of a handle rocker arm, and operates a locking piece by linear movement.

However, the above structures all have the following disadvantages: the height and width of the plug-in circuit breaker are only about 4x2cm, and the front end face of the circuit breaker needs to be provided with an operation part and a wire outlet to connect a wire outlet terminal, and the installation space of the cabinet is narrow, so that the wire of the wire outlet terminal can be pressed against the operation part (a button and a handle), and the operation of a user is inconvenient. The interference of the wire to the operation part is also easy to cause the risk of incomplete switching-on (virtual switching-on) and the risk of incomplete switching-off when the product has short circuit/overload fault, thus causing great potential safety hazard for users.

Furthermore, the wire baffle and the breaker shell are of an integrated structure.

Further, the wire baffle is detachably connected with the breaker shell.

Further, the side of preceding terminal surface be equipped with the mounting groove, the stop line baffle on be equipped with draw-in groove portion, make the stop line baffle install on the terminal surface before through the combination of mounting groove and draw-in groove portion.

Furthermore, the wire blocking partition plate is adhered to the front end face.

Further, the wire baffle is a rectangular, semicircular or polygonal plate.

Furthermore, the side edge of the suspended end of the line blocking baffle plate is provided with an inward concave arc surface.

Furthermore, both sides of the wire blocking partition plate are provided with guard plates, and the guard plates and the wire blocking partition plate form a concave structure.

Further, the circuit breaker housing has a housing opening in an upper surface thereof for extending the locking mechanism of the circuit breaker.

A plug-in circuit breaker uses a plug-in circuit breaker housing structure as described in any one of the above.

Compared with the prior art, the invention has the following beneficial effects:

1. the invention can better separate the conducting wires of the operating part and the connecting terminal by arranging the wire baffle, avoid the interference of the conducting wires to the operating part, overcome the defect that the opening and closing switch does not move in place, and improve the convenience of user operation.

2. The wire baffle and the detachable installation of circuit breaker casing are convenient for maintain and change, and the user can choose the wire baffle of different grade type for use to replace according to actual conditions, arranges the wire better.
