The rear cover portion 1120 is connected to the highest point of the first inclined section 1126. The rear cover portion 1120 is provided with a mounting groove 1121, and two mounting grooves 1121 are provided. A snap-fit ​​portion 1210 corresponding to the mounting groove 1121 is provided in the middle of the upper cover 1200. The snap-fit ​​portion 1210 is a buckle, and the snap-fit ​​portion 1210 includes a cantilever 1230 and a conical hook 1240. The cantilever 1230 is located in the middle of the upper cover 1200 and corresponds to the position of the mounting groove 1121. The cantilever 1230 extends in a direction away from the upper cover 1200, that is, the cantilever 1230 extends from top to bottom, which can also be understood as the cantilever 1230 extending toward the lower cover 1100, and a conical hook 1240 is provided at the end of the cantilever 1230. A pair of clamping parts 1210 are provided, the number of the clamping parts 1210 is consistent with the number of the mounting grooves 1121, and the direction of the clamping parts 1210 extends downward, so that the conical hook 1240 of the clamping part 1210 can be clamped in the mounting groove 1121 of the rear cover part 1120 of the lower cover 1100, and the clamping part 1210 of the upper cover 1200 matches the mounting groove 1121 of the rear cover part 1120 of the lower cover 1100, so as to clamp and fix the upper cover 1200 on the upper rear side of the rear cover part 1120 of the lower cover 1100, and then assemble into a complete shell 1000.

[0041] It should be noted that the upper cover 1200 is provided with an arc-shaped inner wall, and the lower part of the arc-shaped inner wall is an inner cavity, which is used to accommodate the terminal 2000.
