Signal lines are needed to transmit signals, and signal line connectors are needed to connect signal lines to other devices. Signal line connectors are important components for connecting signal lines. The signal lines they connect can be video, audio, data or other types of signal lines. Signal line connectors are divided into many different types according to the type of interface, such as HDMI, RCA, VGA, USB, LAN, etc. Signal line connectors are widely used in various electronic devices, such as TVs, stereos, computers, mobile phones, etc. When these devices need to be connected together, or when they need to be connected to other devices or systems, signal line connectors play an important role.

The signal is often not a standard rectangular wave signal, which causes multiple reflected signals to be superimposed on the original signal, thereby forming an overshoot problem. If the overshoot amplitude is large or the duration is long, it may cause circuit components to fail and affect the normal signal transmission. Therefore, a signal quick connector device is needed to solve the above problem. Utility Model Content
