Description

Connection extension mechanism for signal transmission lines

The present invention relates to a connection extension mechanism for a signal transmission line, which can extend the length of the signal transmission line and improve the strength of the connection without additionally setting a female and male connector on the signal transmission line for connection, and can compensate for the attenuation and distortion of the transmission signal , At the same time, it can improve the signal attenuation caused by the possible interference and poor waterproof performance of the plug-in connector.

The signal transmission line is mainly used to transmit high-frequency signals. During the transmission process, the energy of high-frequency signals is easily radiated from the transmission line to the outside in the form of electromagnetic waves. The higher the frequency of the transmission signal, the more serious the energy loss will be. Therefore, signal transmission lines are usually equipped with related structures, such as shielding structures around the signal transmission line, to prevent high-frequency signal energy loss and external signal interference.

Generally speaking, the length of the signal transmission line has its limitations. If the overall length of the signal transmission line is longer, the copper conductor voltage drop will be greater, and the power attenuation will be greater. If it exceeds a certain range, it will often cause damage to the signal transmission and cause signal transmission. Errors or distortions occur. For example, the length of the USB signal transmission line is mostly within 3 meters, and 1.2 meters is better. In practical applications, if the frequency of the transmission signal is higher, the length of the signal transmission line may be shorter to prevent errors in signal transmission.

The chip connecting the two signal transmission lines can be used to compensate and reduce the attenuation of the transmission signal.

The insulating shell is used to cover the volume of the metal shell and one end of the two signal transmission lines, so as to form a complete connection extension mechanism between the two signal transmission lines, and prevent the metal shell from directly contacting the external environment. Through the content described in this new model, the length of the signal transmission line can be increased without the need for corresponding male connectors and female connectors on the signal transmission line, which can not only extend the length of the signal transmission line, but also improve the connection strength of the signal transmission line. At the same time, it can compensate or reduce the attenuation of the transmission signal. In addition, it can also improve the interference and signal attenuation caused by poor waterproof performance that may be caused by extending the length of the signal transmission line through the conventional technology through the plug-in connector.
