From smart TVs, high-efficiency washing machines to intelligent refrigerators, the stable operation of these appliances relies on reliable internal connection components. Terminal wires, with their flexibility and reliable connection performance, play a crucial role in the transmission of signals and power within home appliances.   II. Application Details of Terminal Wires   (I) Signal Transmission   1. In Smart TVs Flat cables are commonly used as terminal wires between the main board and the display panel. Generally, these flat cables are FPC (Flexible Printed Circuit) cables. They are highly flexible and bendable, making them convenient for wiring in narrow spaces. The internal wires are made of high-purity copper, which has excellent electrical conductivity and can efficiently transmit high-definition video signals. The cables also have a special shielding layer to resist signal interference, ensuring that the display panel receives accurate image signals. With a high-speed transmission rate, they can support 4K or even 8K video playback, presenting clear and vivid pictures to users. Meanwhile, HDMI cables are also crucial in the signal transmission of smart TVs. They are mainly responsible for connecting external devices such as game consoles and Blu-ray players to the main board of the TV. HDMI cables can transmit high-definition video and audio signals in digital form, supporting high-resolution and multi-channel audio. The terminal wires inside the TV further accurately transmit the signals processed by the main board to the display panel. The two work together to meet the diverse audio-visual signal transmission needs of smart TVs. When connecting the main board of a smart TV to the built - in Wi - Fi module, coaxial cables are used as high - frequency - resistant terminal wires. The central conductor of a coaxial cable is surrounded by an insulating layer, a shielding layer, and an outer sheath, which can effectively shield external electromagnetic interference and stably transmit high-frequency wireless communication signals, enabling the TV to connect to the Internet smoothly and access various online video resources and application software.   2. In Washing Machines Multi - core shielded wires are often used as terminal wires to transmit control signals between the control panel and the motor. The multi-core shielded wires have multiple insulated wires inside, which can transmit multiple control signals simultaneously. Their shielding layers can effectively prevent the signals from being interfered with by the outside world and ensure the accurate transmission of control signals. The multi-core shielded wires can accurately transmit the speed control signals from the control panel to the motor. The wire cores are designed with low resistance, which can quickly and accurately transmit electrical signals, enabling the motor to adjust the rotation speed according to different washing programs. At the same time, terminal wires are also used to connect sensors to the main board, transmitting the signals detected by the water-level sensors and clothes-weight sensors to the main board. The main board adjusts parameters such as washing time and water consumption accordingly to achieve intelligent washing.   3. In Refrigerators The temperature sensors and the control circuit are connected by enameled wires. Enameled wires are made by coating an insulating paint on bare copper wires, which have good insulation performance and flexibility and can adapt to the complex wiring environment inside the refrigerator. The temperature sensors monitor the internal temperature of the refrigerator in real-time and transmit the collected temperature signals to the control circuit through enameled wires. The control circuit sends control commands to devices such as compressors through enameled wires according to the preset temperature range, achieving precise control of the refrigerator's refrigeration system and ensuring that the temperature inside the refrigerator is always maintained within an appropriate range to ensure the freshness and quality of food. In addition to temperature signal transmission, the door-opening and closing detection sensors of the refrigerator are also connected to the control circuit by fine-gauge stranded flexible wires. The stranded flexible wires are made by twisting multiple fine copper wires together, which are soft and easy to bend, facilitating wiring at the movable connection between the refrigerator door and the cabinet. When the refrigerator door is opened or closed, the sensors generate corresponding electrical signals, which are transmitted to the control circuit through the stranded flexible wires. The control circuit can make responses such as turning on or off the interior lighting of the refrigerator and adjusting the refrigeration strategy based on these signals to improve the energy efficiency and usability of the refrigerator.
