The snap-fit ​​part 41 includes a snap-fit ​​body 411 and a snap-fit ​​spring piece 412 disposed on the snap-fit ​​body 411. The box has a first state in which the snap-fit ​​part 41 is located in the connecting groove 3 and the upper end face of the snap-fit ​​spring piece 412 abuts against the lower end face of the first limiting protrusion 21. During installation, the snap-fit ​​part 41 is inserted from the upper opening of the connecting groove 3. The snap-fit ​​spring piece 412 abuts against the first limiting protrusion 21 and is deformed under pressure until it enters the connecting groove 3. Then, the snap-fit ​​spring piece 412 is released from the squeezed state of the first limiting protrusion 21 and returns to its original state. At this time, the upper end face of the snap-fit ​​spring piece 412 abuts against the lower end face of the first limiting protrusion 21 to prevent the mounting fastener 4 from disengaging from the connecting groove 3.

[0036] The first limiting protrusion 21 is provided with a guide portion 211 which can be an arc surface or an inclined surface, facilitating the insertion of the clamping portion 41 into the connecting groove 3.
