Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

As shown in fig. 1-4, the amplifier housing structure according to the preferred embodiment of the present invention includes a housing main body 1, two ends of the housing main body 1 are detachably covered with end covers 2, and the end covers 2 are connected with the housing main body 1 through screws;

the shell main part 1 includes integrated into one piece's L shape upper cover 11 and integrated into one piece's L shape lower cover 12, upper cover 11 reaches the inner wall of lower cover 12 all is equipped with joint spare 13 and PCB board fixed strip 14, just upper cover 11 reaches lower cover 12 passes through joint spare 13 detachably connects.

Based on the amplifier shell structure of above-mentioned technical characteristics, through with

upper cover

11 and 12 structure integrated into one piece of lower cover, use joint spare 13 to connect upper cover 11 and lower cover 12 simultaneously, need not the screw fixation, not only the equipment is convenient, has avoided moreover fixed back because the clearance that the deformation leads to, has improved the appearance quality of product.
