At this time, the first housing 110 is re-covered with the copper busbar 210 .

[0043] It should be noted that in the embodiment of the present application, the first housing 110 is vertically connected to the second housing 120, but it can also be appropriately adjusted according to the shape of the outer shell 220 of the wiring module 200. The first housing 110 is used to cover the copper busbar 210 of the wiring module 200, and the second housing 120 is used to drive the first housing 110 to move along the outer shell 220 of the wiring module 200. Preferably, in order to better cover and protect the copper busbar 210, the first housing 110 is enclosed to form a hollow box structure.

[0044] The present application provides a movable baffle 100, comprising a first shell 110 and a second shell 120 connected to each other, wherein the first shell 110 is provided with a through hole 111, and the copper bar 210 of the wiring module 200 of the circuit breaker can extend from the through hole 111; the second shell 120 is provided with a sliding portion 121 and a reset mechanism, and the movable baffle 100 can be slidably connected with the wiring module 200 through the sliding portion 121; the movable baffle 100 can be reset by the reset mechanism so that the through hole 111 blocks the copper bar 210.

The abutment portion 122 includes a first protrusion 1221 and a first limiting portion 1222.

[0052] By setting the connecting plate 1211, the sliding portion 121 can be more easily extended into the housing 220 of the wiring module 200, and the second limiting portion 1212 can be limited by the shell of the wiring module 200, thereby further improving the stability of the movable baffle 100 connected to the housing 220 of the wiring module 200.
