Description

Technical Field

[0001] This application relates to the field of electronic device technology, and in particular to an electrical connector that can reduce the degree of interference when transmitting high-speed signals. Background Technology

[0002] In recent years, with the rapid increase in demand for high-speed computing, servers, and data center applications, electrical connectors have been widely used in various electronic devices. Electrical connectors typically transmit signals through their internal circuit boards to support multi-channel data exchange. However, as electronic devices increasingly demand high-speed and high-bandwidth data transmission, electrical connectors are required to support signals with even higher transmission rates.

[0003] In existing technologies, the circuit boards inside electrical connectors typically house multiple high-speed signal circuits for data transmission. However, due to the limited spacing between these high-speed signal circuits on the circuit board, crosstalk, impedance discontinuities, or other electromagnetic interference problems are prone to occur during high-speed signal transmission. Such interference reduces signal integrity, leading to an increased transmission error rate and failing to meet the stability and reliability requirements of servers or high-speed computing systems.

[0004] To mitigate these issues, existing technologies attempt to reduce signal interference by adding grounding layers, shielding structures, or adjusting the routing of high-speed signal circuits within the electrical connector's internal circuit board. However, such designs often require increasing the number of circuit board layers or structural complexity, leading to increased connector size or manufacturing costs. Furthermore, improper internal circuit board design can cause impedance discontinuities due to excessive grounding layers and shielding structures, which may actually reduce the connector's efficiency during high-speed signal transmission.

[0005] As can be seen from the above, how to effectively improve the signal interference and inefficiency of existing electrical connectors during high-speed signal transmission while maintaining the miniaturization of electrical connectors is a problem that urgently needs to be solved by those in the relevant technical field.
