Preferably, the housing 10 is rectangular in shape, and provides sufficient longitudinal space to achieve the effects of multiple component mounting and accommodation. Of course, other shapes can be adopted according to the use requirement, and the application is not limited in the application. Further, a detachable upper cover is arranged at the top of the shell 10; the upper cover is detachably connected with the top of the housing 10 by means including but not limited to bolts or screws, so that the effect of easily opening or closing the space of the housing 10 can be achieved, the effect of easily installing other components inside the housing 10 can be achieved, and a good component matching effect can be achieved. Further, the upper cover is clamped with the shell 10; the effect of easy dismouting can be realized.
