DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-2 The technical solution provided by the present invention specifically includes the following embodiments: Embodiment: A high-speed FFC cable comprises a cable body 1, the number of the cable bodies 1 is two, a printed circuit board 2 is fixedly disposed at one adjacent end of the two cable bodies 1, a cable plug 3 is fixedly connected at one outer end of the two cable bodies 1, and the two cable plugs 3 and the cable body 1 are symmetrically distributed. The printed circuit board 2 includes a first power input unit 204, a second power input unit 205, a voltage unit 208, a first signal input unit 201, a second signal input unit 202, a third signal input unit 219 and a fourth signal input unit 229. The first signal input unit 201, the second signal input unit 202, the third signal input unit 219 and the fourth signal input unit 229 are respectively electrically connected to the signal transmission line inside the cable body 1, and the first power input unit 204 and the second power input unit 205 are respectively electrically connected to the power transmission line inside the cable body 1.

[0019] The output end of the first power input unit 204 is electrically connected to the first diode 206, the output end of the first diode 206 is electrically connected to the first connection point 209, the output end of the voltage unit 208 is electrically connected to the receiving end of the first connection point 209, the output end of the second power input unit 205 is electrically connected to the second diode 207, the output end of the second diode 207 is electrically connected to the first connection point 209, the output end of the first connection point 209 is electrically connected to the capacitor 224, the output end of the capacitor 224 is electrically connected to the alternating resistor 225, and the output end of the alternating resistor 225 is electrically connected to the receiving end of the left cable body 1; When the first power input unit 204 and the second power input unit 205 are supplying power, the voltage is first stabilized by the first diode 206 and the second diode 207.

Thus, the input power is switched from the first power input unit 204 to the second power input unit 205. When the second power input unit 205 is powered off, the voltage of the voltage unit 208 drops due to the non-conduction of the second diode 207, so that the first diode 206 is turned on, and the first amplifier 226 is restored to be powered by the first power input unit 204, thereby completing the stabilization of the power input unit voltage. The current firstly powers the first amplifier 226 through the first amplifier 226, and then performs secondary voltage stabilization through the third diode 227, and finally transmits the electric energy to the second amplifier 228, completing the second amplifier The energy supply of the amplifier 228 enables the first amplifier 226 and the second amplifier 228 to normally enhance the electrical signal. The current is delayed through the capacitor 224 to prevent more current from being unable to pass through the alternating resistor 225, causing loss of the alternating resistor 225. The current can be stable and stably pass through the alternating resistor 225 to enter the cable body 1 on the left, and then input to the screen through the cable body 1 and the cable plug 3 to light up the screen. The current and voltage output of the cable are stable. Even if a single output line has a problem, it can still be powered and will not affect the device, which is convenient for use of the device.

[0027] In the present scheme, when a high-speed FFC cable is working, the right cable plug 3 is inserted into the signal device for welding, and then the left cable plug 3 is inserted into the screen to complete the signal connection between the signal device and the screen. The signal device simultaneously supplies power to the screen and transmits signals. The signal is transmitted through the first signal input unit 201, the second signal input unit 202, the third signal input unit 219 and the fourth signal input unit 229. The first signal input unit 201 and the second signal input unit 202 are USB signal sources. The first signal input unit 201 stabilizes the signal through the first resistor 210. When the signal is unstable, it is derived through the second signal grounding unit 223.

The third signal input unit 219 and the fourth signal input unit 229 are network signal sources. When the first signal input unit 201 and the second signal input unit 202 are in use, the third signal input unit 219 and the fourth signal input unit 229 cannot be used, and the signal is exported through the second signal grounding unit 223. The screen will not receive the signal transmitted by the third signal input unit 219 and the fourth signal input unit 229.

When the second power input unit 205 has power and the voltage of the second power input unit 205 is greater than that of the first power input unit 204, at this moment, the voltage of the voltage unit 208 is greater than that of the first power input unit 204, so the first diode 206 cannot be turned on to supply power to the first amplifier 226, and the second power input unit 205 supplies power to the first amplifier 226. Thus, the input power is switched from the first power input unit 204 to the second power input unit 205. When the second power input unit 205 is powered off, the voltage of the voltage unit 208 drops due to the non-conduction of the second diode 207, so that the first diode 206 is turned on, and the first amplifier 226 is restored to be powered by the first power input unit 204, thereby completing the stabilization of the power input unit voltage. The current firstly powers the first amplifier 226 through the first amplifier 226, and then performs secondary voltage stabilization through the third diode 227, and finally transmits the electric energy to the second amplifier 228, completing the second amplifier The energy supply of the amplifier 228 enables the first amplifier 226 and the second amplifier 228 to normally enhance the electrical signal. The current is delayed through the capacitor 224 to prevent more current from being unable to pass through the alternating resistor 225, causing loss of the alternating resistor 225. The current can be stable and stably pass through the alternating resistor 225 to enter the cable body 1 on the left, and then input to the screen through the cable body 1 and the cable plug 3 to light up the screen. The current and voltage output of the cable are stable. Even if a single output line has a problem, it can still be powered and will not affect the device, which is convenient for use of the device.
