[0018] In order to facilitate the understanding of those skilled in the art, the utility model is further explained below in combination with examples and drawings, and the content mentioned in the implementation manner is not a limitation of the utility model. The utility model is described in detail below in combination with drawings.

[0019] As shown in Figure 1 and Figure 2 The utility model discloses a kind of multi-functional partition cover of moulded case circuit breaker, including cover 1, multiple partition pieces 2 are arranged in cover 1 with interval, the container 3 for accommodating into gas copper bar or outgoing gas cable is formed between adjacent partition pieces 2 or between partition piece 2 and the inner side wall of cover 1, the top of the partition piece 2 is equipped with extension groove 13, extension groove 13 is provided with partition board 4, breakage groove 5 is arranged at the junction of extension groove 13 and partition board 4, breakage groove 5 is used to be disconnected by external force to make the container 3 on the both sides of this partition board 4 be communicated with each other.

[0020] That is, when the utility model is made, breakage groove 5 is shaped between partition board 4 and extension groove 13 after the utility model is injection molded, the thickness of the position of this breakage groove 5 is less than the thickness of partition board 4, so that when some incoming gas copper bar or outgoing gas cable needs to give way due to specification problem, only needs to knock the breakage groove 5 position of corresponding partition board 4, so that partition board 4 can be separated from extension groove 13, so that extension groove 13 can be used to communicate with two adjacent containers 3 and be used to accommodate incoming gas copper bar / outgoing gas cable.

[0021] And because the utility model is used as a lid, only need to make the extension groove 13 position intercommunication two holding groove 3, without making two holding groove 3 completely intercommunication, can realize the effect of giving way to the corresponding air inlet copper bar / air outlet cable, which is conducive to ensuring the strength of the partition.

[0022] In the embodiment, the top of the partition 2 is provided with a reinforcing member 6 connected with the partition plate 4, and a breaking groove 5 is arranged between the reinforcing member 6 and the partition plate 4.
