Problems solved by technology

[0004] When the connector is used for low-speed signal transmission, the crosstalk interference between the signal terminals is not serious and can be ignored in terms of effect; but when the connector is used for high-speed signal transmission, the crosstalk interference between the signal terminals will cause Serious impact

Abstract

An electric coupler capable of lowering high-frequency crosstalk noise can allow at least two butt joint pieces to be inserted in. The electric coupler capable of lowering the high-frequency crosstalk noise comprises a first connector, a first signal terminal, a second connector, a second signal terminal and a grounding terminal. One of the two butt joint pieces can be inserted into the first connector, and the first signal terminal is used for being electrically connected with the butt joint piece which is inserted into the first connector. The other butt joint piece can be inserted into the second connector, and the second signal terminal is used for being electrically connected with the butt joint piece which is inserted into the second connector. The grounding terminal is electrically connected to the first connector and the second connector and located between the first signal terminal and the second signal terminal. The grounding terminal and the first signal terminal form a signal backflow space, the grounding terminal and the second signal terminal also form a signal backflow space, and the signal backflow spaces serve as signal backflow paths of the first signal terminal and the second signal terminal.

Description

technical field [0001] The invention relates to an electrical connector, in particular to an electrical connector for reducing high-frequency crosstalk noise. Background technique [0002] Today's various electronic devices, such as televisions, tape recorders, VCRs, CD players, and digital video disc (DVD) players, all have plug-and-socket connectors for mutual connection and signal transmission. [0003] Generally, the connector has multiple signal terminals. When the signal is transmitted through the signal terminal, it will cause voltage noise interference to the adjacent signal terminal due to electromagnetic coupling, that is, the mutual interaction of electromagnetic fields caused by different structures in adjacent areas. The effect of electromagnetic field interference is the so-called crosstalk phenomenon (Cross Talk). In other words, crosstalk interference occurs between the signal terminals in the connector. see figure 1 and figure 2 , which is the structure...
