As shown in fig. 1, the utility model provides a case of inverter, including case body 1 and cover 2. Wherein, the box body 1 has an opening (not shown in the figure), the cover 2 is disposed on the box body 1 and covers the opening, and the box body 1 and the cover 2 can enclose to form an inner space for accommodating the inner device.

Different from the conventional design, the embodiment of the present invention further includes a deformation component 3, and the deformation component 3 may be fixedly disposed, specifically, may be fixedly assembled with the case body 1, or may be connected with some fixed structures (such as a wall body, etc.) in the environment where the case is located, so as to form a first connection position; also, the deformation member 3 may be coupled to the cover 2 to form a second coupling position.

Adopt this kind of scheme, when the inner part device breaks down, the operation is unusual, and then when initiating the explosion accident, cover 2 receives the explosive force effect, can move towards the direction of keeping away from case body 1. In the process, the deformation component 3 can deform to absorb the explosive force and buffer the displacement of the cover 2, so that the force acting on the deformation component 3 and the two connecting positions can be relatively small, the possibility that the two connecting positions of the deformation component 3 and the deformation component 3 are damaged is relatively low, the deformation component 3 can limit the displacement stroke of the cover 2, the possibility that the cover 2 is directly exploded is low, and the safety of the case can be high.

The embodiment of the utility model provides a deformation part 3 that sets up does not prevent cover 2 to take place the displacement, but allows cover 2 to take place certain displacement under the effect of explosive force through self deformation, in case cover 2 takes place the displacement relative case body 1, can produce the gap between cover 2 and the case body 1 promptly, and the produced pressure of explosion can leak through this gap rapidly, can further reduce the effect of explosive force to cover 3 again.

So, explosion accident takes place the back, and the damaged risk of cover 2 can reduce, and like this, the possibility that cover 2 secondary comes into operation is higher, can also reduce cost.

In the embodiment of fig. 1, the deformation member 3 is located outside the chassis, so that the intrusion of the deformation member 3 into the internal space can be reduced, and the deformation member 3 is located outside the explosion space, so that the influence of the explosive force on the deformation member 3 and the connection position of the deformation member 3 can be reduced. Of course, in particular practice, a solution is also possible in which the deformation element 3 is arranged inside the cabinet, i.e. the deformation element 3 may be arranged in the inner space; thus, damage to the deformable member 3 due to human factors and the like can be reduced.

Further, the utility model provides a machine case can also include connecting piece 4, and connecting piece 4 is used for connecting cover 2 and case body 1, can improve the connection reliability of cover 2 and case body.
