Problems solved by technology

[0003] In consumer communication devices, such as 5G mobile phones, due to the high refresh rate of the screen, the large number of antennas and the location near the edge of the screen, a very good grounding is required between the screen and the metal mid-plane to eliminate or weaken signal stray (RSE) ; Especially for flexible OLED screens, due to the small grounding space (generally less than 0.4㎜) and small stress (generally less than 2N), there are higher requirements for the grounding scheme. At this time, the conventional welding metal shrapnel is no longer applicable

Embodiment 1

[0072] Such as figure 1 , 2 As shown, the grounding elastic body provided in this embodiment includes: an elastic core 10, a PET double-sided adhesive layer 20, a PI film 30, a conductive layer 40 and an insulating non-substrate adhesive layer 60, and the elastic core 10 adopts polyurethane foam Cotton, the conductive layer 40 is copper foil with gold plating on the outer surface; the overall length of the grounding elastic body is 6 mm, the length of the welding part is 2.6 mm, and the overall width of the grounding elastic body is 2.5 mm. In the natural state, the elastic core is 10 mm The overall height is 0.76mm, the thickness of the PI film 30 is 0.015mm, the thickness of the PET double-sided tape 20 is 0.01mm, the thickness of the conductive layer 40 is 0.03mm, and the thickness of the insulating non-substrate adhesive layer 60 is 0.01mm.

Embodiment 2

[0074] Such as image 3 As shown, the grounding elastic body provided by this embodiment differs from that of Embodiment 1 only in that a metal reinforcing plate 50 is bonded to the upper surface of the welding part 40, and the metal reinforcing plate 50 is provided with a PU layer on the upper surface. Copper foil, and the thickness of the metal reinforcing plate 50 is 0.018mm; other features are completely the same as those in Embodiment 1, and will not be repeated here.

Abstract

The application discloses a grounding elastic body and electronic equipment, comprising: an elastic core, PET double-sided tape, PI film and conductive layer sequentially arranged on the outer surface of the elastic core; the PI film is laminated and bonded to the PET double-sided tape The outer side of the PET double-sided tape is attached to the upper surface of the elastic core, and the two ends of the PET double-sided tape are respectively bypassed on the left and right sides of the elastic core and then overlapped and attached to the lower surface of the elastic core. On the surface, one end of the conductive layer is bonded to the upper surface of the elastic core, and the other end of the conductive layer is attached to the lower surface of the elastic core after bypassing the left side of the elastic core, and is convex to the right relative to the elastic core. The PET double-sided tape includes a PET substrate and glue coated on both sides of the PET substrate respectively, and the thickness of the PET double-sided tape is ≤0.015mm. The overall resilience performance, impedance performance, product stability and welding stability of the grounding elastic body of the present application are all effectively improved, and at the same time, it is convenient for production and manufacturing, and it is convenient for realizing small-sized product manufacturing.

Description

technical field [0001] The present application relates to the technical field of communication equipment, in particular to a grounding elastic body and electronic equipment including the same. Background technique [0002] In a communication device, in order to avoid signal interference or eliminate static electricity, a grounding elastic body or a welding shrapnel is generally used for electrical connection between two interfaces that need to be grounded. This kind of electrical connection requires as high a stability as possible, and also needs to ensure batch consistency, especially in the grounding area of ​​the RF antenna. [0003] In consumer communication devices, such as 5G mobile phones, due to the high refresh rate of the screen, the large number of antennas and the location close to the edge of the screen, a very good grounding between the screen and the metal mid-plane is required to eliminate or weaken the signal spurious (RSE) ; Especially for flexible OLED sc...
