Background In the age of rapid development of digitalization and informatization, electronic devices are increasingly widely and deeply applied in various fields, and the performance requirements of the electric connectors are increasingly improved. As an indispensable key component in electronic devices, electrical connectors have assumed important roles for achieving electrical connection and signal transmission. With the continuous advancement of technology, electronic devices are increasingly powerful, and existing electrical connectors are required to transmit not only huge amounts of data, but also data at higher transmission rates. For example, in the field of high-speed communication, the popularity of 5G technology has led to an exponential increase in data transmission, which presents an unprecedented challenge to the data transmission capability of electrical connectors, and in the field of high-performance computers, the cooperation of multi-core processors, mass memories, and high-speed storage devices, also requires that electrical connectors be capable of transmitting large amounts of data quickly and accurately.
