Abstract
Description
technical field
[0001] The invention relates to the technical field of computer reinforcement, in particular to a structure in which screen lines at the hinges of a portable computer are protected from rain and electromagnetic compatibility. Background technique
[0002] The area where the hinge of the portable reinforced computer goes through the screen is an area where electromagnetic leakage is relatively serious. At present, the treatment method of shielding electromagnetic waves by wrapping conductive tape on the screen wire and applying waterproof glue to prevent rain has the following disadvantages:
[0003] 1) The electromagnetic shielding effect is unstable and unsatisfactory, and the electromagnetic leakage often exceeds the standard;
[0004] 2) The method of preventing rain by applying waterproof glue is an irreversible treatment method, which is not conducive to repair;
[0005] 3) The processing method is complicated, especially the effects of different worke...
Examples
Embodiment 1
[0026] Such as figure 1 , figure 2 As shown, the screen line at the hinge of the portable computer is a structure that takes into account both anti-drenching rain and electromagnetic compatibility. The structure includes two parts: rubber sleeve 3 and magnetic ring pressure plate 2, wherein:
[0027] The structure of the rubber sleeve 3: a cylindrical structure, a raised edge is arranged at the lower part of the middle of the cylinder, and the distance from the upper part of the cylinder to the raised edge is equivalent to the thickness of the base;
[0028] The structure of the magnetic ring pressing plate 2 includes a ferrite magnetic ring 7 and a metal pressing plate 8. The ferrite magnetic ring 7 is an annular columnar body fixed on the metal pressing plate 8. There is a circle at the connection between the metal pressing plate 8 and the annular columnar body. The hole, the round hole and the inner wall of the annular column form a through hole, and the shape of the inne...
Embodiment 2
[0032] On the basis of Example 1, ferrite wave-absorbing material particles 5 are evenly distributed in the rubber sleeve 3 of this example, so as to realize the function of conductive continuity and converting electromagnetic energy, and the ferrite wave-absorbing material is efficient The wave-absorbing filling medium can not only effectively absorb and transform electromagnetic wave energy, but also ensure the continuity of electrical conductivity at the connection.
Embodiment 3
[0034] On the basis of Embodiment 1, a closed flexible metal coil 4 is implanted around the wall of the rubber sleeve 3 in this embodiment to weaken the leakage of electromagnetic waves. The flexible metal coil can ensure sufficient deformation of the rubber, and at the same time according to the electrical The principle of magnetic induction cancels out the leaking electromagnetic waves.
