What is a weak electrical connector? What are the main types of weak electrical connectors function as well as characteristic features electrical performance parameters?

Weak power connectors are connectors used for transmitting low voltage and low current signals, mainly used for signal transmission and control in electronic devices. Compared with strong connectors (used for high voltage and high current connections), weak connectors usually have smaller size, lower power and higher signal transmission accuracy. Main types and functions: 1. D-Sub connector: D-Sub connector is a common weak power connector, commonly used in computers and communication equipment, mainly used for transmitting serial data, parallel data and control signals. 2. HDMI connector: HDMI (High Definition Multimedia Interface) connectors are widely used for High Definition video and audio transmission, can be used to connect the TV, monitor, stereo and other devices.3. USB Connector: USB (Universal Serial Bus) connector is a common weak power connector, used to connect a variety of devices, such as computers, cell phones, cameras, etc., for data transmission, charging and peripheral connections.4. RJ45 Connector: RJ45 Connector Used for network communication, mainly used to connect Ethernet devices, such as computers, routers, switches, etc. 5.RCA Connector: RCA (Radio Corporation of America) connectors are usually used for audio and video transmission, such as connecting stereo, TV, video cameras and other equipment. Features and characteristics: 1. miniaturization: weak connectors usually have a small size, easy to install and wiring. 2. signal transmission accuracy: weak connectors require good signal transmission accuracy to ensure reliable data transmission and accuracy. 3. plugging reliability: weak connectors are usually plugged in and out of the number of times, and therefore require good plugging reliability and durability. 4. shielding performance: weak Connectors in high-frequency signal transmission needs to have good shielding performance to prevent interference and signal loss. 5. Electrical performance parameters: rated current: the connector can withstand the value of the larger current. 6. Impedance: the degree of resistance matching between the connector and the circuit. Insulation resistance: the insulation resistance between the connector plug and socket. Differential mode noise suppression: the connector's ability to suppress differential mode noise during transmission. Crosstalk: The degree of interference between neighboring signals in the connector.
