Description

Technical Field

[0001] The utility model relates to the technical field of smart televisions, in particular to a PCDN-based smart television. Background Art

[0002] PCDN technology is widely used in scenarios such as smart TV live video streaming, file downloads, and software updates to provide a better user experience and more efficient content transmission services.

[0003] However, the existing smart TV PCDN wiring is often that the cable is directly plugged into the interface end of the smart TV back panel. When in use, the cable is easily loosened due to being pulled apart, affecting the interface stability and resulting in poor signal transmission quality. In addition, the interface is set on the TV back panel and is directly exposed to the outside, without the function of anti-electromagnetic interference. The surrounding components are likely to affect the cable interface during operation, which is not conducive to use. Therefore, we propose a smart TV based on PCDN. Utility Model Content

[0006] Preferably, a pcdn cable is movably plugged into the pcdn interface, and the pcdn cable is electrically connected to the pcdn interface.

[0007] Preferably, the outer dimensions of the limit slider are matched with the inner dimensions of the limit groove, and the limit slider is slidably engaged in the limit groove.

[0008] Preferably, a soft rubber pad is fixedly adhered to one side of the clamping plate.

[0009] Preferably, the clamping plates are symmetrically distributed on both sides of the pcdn interface.

[0010] Preferably, the inner surface of the rear cover is evenly coated with an anti-electromagnetic coating.
