背景技术Background technique
电连接器是实现导电互连的元器件，其在电子通讯领域有较为广泛的应用。其中差分连接器主要被用于需要高速、高质量传输电信号的使用环境中，以其低功耗、低误码率、低串扰和低辐射等特点，逐渐成为主流的电连接器。串扰是影响差分连接器的信号完整性的因素之一，是指有害信号从一个网络通过耦合转移到相邻网络并对上述相邻网络产生影响，影响电信号的传输速度和传输质量。随着信号传输速率越来越高,如何避免或者减弱差分对间的耦合就显得越来越重要。Electrical connectors are components that realize conductive interconnection, and are widely used in the field of electronic communications. Among them, differential connectors are mainly used in environments that require high-speed and high-quality transmission of electrical signals. With their low power consumption, low bit error rate, low crosstalk and low radiation, they have gradually become mainstream electrical connectors. Crosstalk is one of the factors affecting the signal integrity of differential connectors, which means that harmful signals are transferred from one network to adjacent networks through coupling and have an impact on the above-mentioned adjacent networks, affecting the transmission speed and transmission quality of electrical signals. With the increasing signal transmission rate, how to avoid or weaken the coupling between differential pairs becomes more and more important.
现有技术中的屏蔽结构大致可分为三类：差分对单边半屏蔽、差分对双边全屏蔽和差分对周围全屏蔽。如图1所示，差分对双边全屏蔽在差分对101的两侧均设置屏蔽片102，其优点在于能够实现较高的传输速率，但缺点在于使用了双边全屏蔽结构的差分对接触件模块的屏蔽片102与接触件需要采用激光电焊的方式实现连接，装配可靠性不高。The shielding structures in the prior art can be roughly divided into three categories: single-side half-shielding for differential pairs, bilateral full-shielding for differential pairs, and full-circumferential shielding for differential pairs. As shown in FIG. 1, the double-sided full shielding of the differential pair is provided with
