Abstract: A video transmission connector component comprises a video transmission connector and a circuit substrate. The circuit substrate at least includes a regulation module; wherein the circuit substrate is coupled with a pin group of the video transmission connector through a first pad set arranged on the circuit substrate; wherein the regulation module includes a control unit and a redriver. The redriver is configured to couple to at least one signal transmission pin of the pin group of the video transmission connector. Wherein the control unit is coupled to the redriver and the redriver receives at least one relay parameter which is used to adjust signals transmitting to the at least one signal transmission pin.

Abstract: A transmission cable includes a transmission cable, a first circuit board having a first power layout area, a first ground layout area, and a first circuit trace, and a second circuit board having a second power layout area, a second ground layout area, and a second circuit trace. The transmission cable includes a power wire, a pair of signal wires, and a drain wire. When the first power layout area, the first circuit trace, the second power layout area, and the second circuit trace are connected via a resistor, respectively, the drain wire connected between the first circuit trace and the second circuit trace will act as another power wire. Thus, a voltage drop at both ends of the transmission cable can be reduced by increasing the power wires to improve signal transmission quality.

Abstract: A power inlet adapter for connecting a signal transmission line and a first device is disclosed. The power inlet adapter includes a main body and a power inlet end. The main body includes a socket end, a plug end, and a circuit board. The power inlet end is configured to electrically couple with a first socket to receive a second power signal, wherein the power inlet end is connected to the main body through a connecting cable and electrically coupled to the circuit board via conducting wires in the connecting cable. The circuit board has a control module configured to receive the first power signal and the second power signal. The control module is configured to provide an output power signal to the socket end by regulating the first power signal and the second power signal.

Abstract: A transmission cable includes a terminal connector and a line set. The terminal connector includes a circuit board and a setting head having a power terminal, a grounding terminal, and a first signal terminal. The line set includes a signal transmission unit having a first signal transmission part and a drain wire. The first signal transmission part is electrically coupled to the first signal terminal via the circuit board, and the drain wire is electrically connected to the power terminal via the circuit board.

Abstract: An optoelectronic cable comprises an optical fiber wire disposed at the center of the optoelectronic cable, with an armoring layer that is arranged at a periphery of the optical fiber wire. A plurality of electric wires is disposed around the periphery of the optical fiber wire, and an outer sheath is disposed as an outermost layer of the optoelectronic cable. By arranging the armoring layer at the periphery of the innermost optical fiber wire, optical fibers therein can be protected from being damaged by external forces. The overall assembly can also effectively reduce the total diameter, resulting in a softer and more flexible optoelectronic cable highly convenient for packaging and installation.

Abstract: This disclosure provides an active audio and video signal transmission device, which comprises a cable, a display-side connector, and a signal source connector. The cable comprises a first end and a second end. The display-side connector comprises a first shell, a first circuit board configured within the first shell, a first plug configured on the first circuit board and protruded from the first shell, a repeater configured on the first circuit board and electrically connected to the first plug and the first end of the cable, and a microprocessor.
