The rear case 2 can be fixedly coupled to the rear side of the back cover 13 by the second snap elements 22 being snapped on the first snap elements 14 respectively. In addition, the corresponding blocking surfaces 149 of the side baffles 142 of the first latching members 14 adjacent to the end wall portions 134 abut against and block the corresponding blocking surfaces 142 disposed in the same direction along the vertical direction Z. The surface 231 of the bump 23 can prevent the rear case 2 from shaking relative to the back cover 13 along the up-down direction Z. The corresponding stop surfaces 149 of the side baffles 142 of the first latches 14 disposed in the same direction along the left-right direction Y and adjacent to the side wall portions 135 (as shown in FIG. 6 ) abut against each other. And blocking the surface 231 of the corresponding bump 23 can prevent the rear case 2 from shaking relative to the back cover 13 along the left-right direction Z. Thereby, the rear case 2 can be more firmly fixed to the back cover 13 .

Referring to FIG. 10 , when the rear case 2 is to be detached from the back cover 13 , the operator pulls the rear case 2 backward along a disassembly direction D2 opposite to the assembly direction D1 (as shown in FIG. 7 ). Since the second rear slope 224 of the hook portion 222 of each second buckle 22 is blocked by the corresponding first front slope 147 , the second rear slope 224 is applied to the second rear slope 224 by the first front slope 147 . The component force pushes the second rear slope 224 , urges the second rear slope 224 to slide along the first front slope 147 , and drives the arm 221 to bend and deform relative to the rear wall 211 to accumulate restoring elastic force. When the hook portion 222 moves away from the corresponding card When the groove 145 and the corresponding buckle portion 146 are in place, the hook portion 222 is automatically returned to the position shown in FIG. , the disassembly of the rear case 2 is completed.

Referring to FIG. 7 , FIG. 8 and FIG. 10 , with the design of the first latching parts 14 and the second latching parts 22 , the operator can push the rear case 2 in a single direction along the assembling direction D1 .
