After the first rear housing 21 and the backboard 1 are fastened in place, in order to prevent the first rear housing 21 from falling off, two screws are arranged below (extending part of) the first rear housing 21 for fixing, so as to strengthen the fixation of the first rear housing 21 and the backboard 1. It will be appreciated that the screw structure may be covered by the second rear case 22 without being exposed, thereby ensuring the aesthetic appearance of the overall structure of the cabinet.

The second rear case 22 can be fixed with the back plate 1 through the plug-in assembly and the clamping and positioning assembly. The number of the plug-in components is multiple, and the plug-in components are arranged at the upper end of the second rear shell 22 in the width direction of the backboard 1; the plugging direction of the plug assembly may be from bottom to top along the width direction of the backplane 1 (vertical direction in fig. 1). The clamping and positioning components are respectively arranged at two ends of the backboard 1 in the length direction.

The second rear case 22 and the back plate 1 can be assembled and fixed in the following manner: the second rear case 22 is placed on the back plate 1, and is slid from bottom to top, and the insertion tongue 31A is inserted into the corresponding insertion groove 31B. When the inserting tongue 31A and the inserting groove 31B are inserted in place, the second rear shell 22 can be directly pressed, so that the locking tongue 32 of the locking and positioning structure is limited in the limiting locking groove 32B, and the second rear shell 22 is fixed with the back plate 1.
