The production cost of product is reduced while sealing effectiveness is ensured.
In above-mentioned embodiment, the second horizontal plane 32 and first foam of underrun 41 of shell 4 of MIC supports 3 are sealed.Its
In, foam good seal, MIC supports 3 are tightly connected with shell 4 by the first foam 41, can be improved MIC supports 3 and be sealed with shell 4
Reliability.From this sealing means, when mobile terminal goes wrong, can easily by the first foam 41, MIC supports 3 with
Shell 4 is taken apart, facilitates product to repair.
In above-mentioned embodiment, the vertical 33 of MIC supports 3 is sealed with the side of shell 4 by the second foam 42.Its
In, foam good seal, MIC supports 3 are tightly connected with shell 4 by the second foam 42, can be improved MIC supports 3 and be sealed with shell 4
Reliability.From this sealing means, when mobile terminal goes wrong, can easily by the second foam 42, MIC supports 3 with
Shell 4 is taken apart, facilitates product to repair.
Further, as shown in figure 8, for fixing seal MIC supports, in the corresponding position of the bottom surface of shell 4 and MIC supports 3
The place of putting is respectively arranged at two ends with the position of bone 43, can be clamped on MIC supports 3 by two position of bone 43.The bottom surface of shell 4 and MIC supports 3
Bondd by gum, so as to fix on MIC supports 3 on the bottom surface of shell 4.
The MIC sealing structures that the present invention is provided, by the second face seal of the first level face of MIC supports and pcb board, MIC
Second horizontal plane of support is sealed with enclosure bottom, and the vertical of MIC supports is sealed with the side of shell, forms firm sealing
System, effectively prevent deformation and the leakage mail topic of sealing system during use.Additionally, the sealing structure assembles letter
It is single, quick, improve production and assembly efficiency.
