Embodiment 1
[0045] Example 1: as Figure 9 The elastic sheet 31 shown is an unnotched sheet 31a, which is a full sheet without any notches.
[0046] Implementation two: if Figure 10 The elastic sheet 31 shown is a rectangular slot sheet 31b, and a rectangular slot 310 is provided at the sealing working end of the elastic sheet, so that the elastic sheet has more elasticity when working.
[0047] Implementation three: as Figure 11 The elastic sheet 31 shown is a serrated notch sheet 31c, the notch of the sealing working end of the elastic sheet 31 is formed into serrated notch 311, and each serrated notch 311 is in a trapezoid shape.
[0048] In the length direction of the component mounting main board 33, the interface between the sealing element 3 and the sealing element also has various embodiments, see Figure 12 .
[0049] Embodiment 1 of the interface between the sealing elements 3: the form of concave-convex fit, such as Figure 13 , When assembling the elastic sheets, each s...
