请参阅图1，图1是本申请实施例提供的一种通信系统1000的示意图。
通信系统1000包括第一设备100、线缆组件200以及第二设备300。线缆组件200连接在第一设备100与第二设备300之间。需要说明的是，图1以及下文相关附图仅示意性地给出了通信系统1包括的一些部件，这些部件的实际形状、实际大小、实际位置和实际构造不受图1以及下文各附图限定。
示例性地，第一设备100可以为机顶盒(也称为数字视频变换盒，set top box，STB)、电脑主机、投影仪、交互式网络电视(internet protocol television，IPTV)盒子、网络机顶盒(over the top,OTT)等设备。第二设备300可以为屏幕、平板电脑(tablet personal computer)、膝上型电脑(laptop computer)、个人计算机、笔记本电脑、车载设备、可穿戴设备、增强现实(augmented reality，AR)眼镜、AR头盔、虚拟现实(virtual reality，VR)眼镜或者VR头盔等显示设备。
一些实施例中，第一设备100是智慧屏，第二设备300是机顶盒。线缆组件200连接在智慧屏和机顶盒之间。当机顶盒通电时，机顶盒可以通过线缆组件200向智慧屏传输电力，以使屏幕通电。这样，屏幕无需通过插头或连接器等器件直接电连接于外部电源，屏幕可以省去与外部电源电连接的器件，从而既可以简化屏幕的结构，又可以避免屏幕因设置有与外部电源电连接的器件而导致屏幕的厚度增大，也即有利于屏幕实现薄型化设置。
一些实施例中，第一设备100是电脑显示屏，第二设备300是电脑主机。示例性地，电脑显示屏可以放置于桌面上。其中，线缆组件200连接在电脑主机与电脑显示屏之间。当电脑主机通电时，电脑主机可以通过线缆组件200向电脑显示屏传输电力，以使电脑显示屏通电。这样，电脑显示屏无需通过插头或连接器等器件直接电连接于外部电源，电脑显示屏可以省去与外部电源连接的器件，从而既可以简化电脑显示屏的结构，又可以避免电脑显示屏因设置有与外部电源电连接的器件而导致电脑显示屏的厚度增大，也即有利于电脑显示屏实现薄型化设置。
另一些实施例中，第一设备100是VR眼镜，第二设备300是电脑主机。线缆组件200连接在电脑主机与VR眼镜之间。由于电脑主机可以通过线缆组件200向VR眼镜传输高速信号。这样，VR眼镜可以呈现高清且较为流畅的虚拟场景。用户的体验性较高。故而，线缆组件200在VR的应用领域内也是较佳选择。
如图1所示，以第一设备100是智慧屏，第二设备300是机顶盒为例进行阐述。一些实施例中，通信系统1000为包括智慧屏100、线缆组件200以及机顶盒300的视频通信系统。示例性的，智慧屏100包括母端连接器1001，机顶盒300包括母端连接器3001，线缆组件200的两端分别设有两个公端连接器(2001、2002)，公端连接器2001可以插接智慧屏100的母端连接器1001，公端连接器2002可以插接机顶盒300的母端连接器3001，以使线缆组件200电连接智慧屏100与机顶盒300。配对的母端连接器和公端连接器形成连接器组件。在本申请中，为了使智慧屏100能够满足高清播放及多功能化需求，连接器组件的功率可以等于或大于300W，传输速率可以等于或大于80Gbps，以实现大功率和高速传输性能。
在传统的视频播放系统中，连接器组件的连接器通常采用USB type-C(universal serial bus type-C，C型通用串行总线)接口结构或HDMI(high definition multimedia interface，高清多媒体接口)结构。USB type-C接口是由USB-IF(USB implementers forum，USB标准化协会)制定的标准接口，其通流能力上限通常为10A，单向传输能力上限通常为40Gbps(每秒1000兆位)。由于USB type-C接口的性能受到协会指定的结构限定，因此难以突破其通流能力上限和单线传输能力上限，无法满足视频播放系统的大功率和高速传输需求。HDMI由HDMI协会定义标准界面，目前最大的传输速率为48Gbps，无供电能力。HDMI由于其结构和界面的固定限制，其传输速率无法突破48Gbps达到更高的传输速率，也无法获得供电能力，因此HDMI也无法满足视频播放系统的大功率和高速传输需求。基于此，本申请提供一种新的连接器组件，其母端连接器及公端连接器采用新的界面设计和结构设计，以满足大功率和高速传输需求。
请结合参阅图2和图3，图2是本申请实施例提供的一种连接器组件10的分解结构示意图，图3是图2所示连接器组件10的组装结构示意图。连接器组件10可以应用于图1所示通信系统1000中。

一些实施例中，第二端子组13包括多个端子131，多个端子131彼此间隔地排布于第一方向X。各端子131均包括接触段131a、连接段131b及尾段131c，连接段131b连接于接触段131a的一端，尾段131c连接于连接段131b远离接触段131a的一端，也即连接段131b连接于接触段131a与尾段131c之间。其中，各端子131的接触段131a均沿第二方向Y延伸；部分端子131的连接段131b整体沿第二方向Y延伸，端子131的连接段131b包括第一部分和第二部分，第一部分连接在接触段131a与第二部分之间，第一部分沿第二方向Y延伸(允许发生该部分偏移)，第二部分相对第一部分弯折；各端子131的尾段131c相对连接段131b的第二部分弯折。其中，第二端子组13包括至少两种端子131结构，这两种端子131结构的主要区别在于端子131的横截面积不同。
一些实施例中，母端连接器1还包括接地片15。接地片15包括第一部分151和第二部分152，第二部分152相对第一部分151弯折，第二部分152的末端形成引脚。
请结合参阅图6A、图6B及图7，图7是图4所示母端连接器1的部分结构沿B-B处剖开的截面结构示意图。
一些实施例中，第一端子组12与第二端子组13堆叠设置，且彼此间隔。第一端子组12与第二端子组13之间形成缝隙、两者不接触。其中，第一端子组12的端子121的连接段121b嵌设于座体111，第二端子组13的端子131的连接段131b嵌设于座体111，以使各端子(121、131)固定于绝缘主体11。端子121的连接段121b的一端可以延伸至舌板112，端子131的连接段131b的一端可以延伸至舌板112。其中，第一端子组12的端子121的接触段121a固定于舌板112,第二端子组13的端子131的接触段131a固定于舌板112，且第一端子组12的端子121的接触段121a和第二端子组13的端子131的接触段131a分别露出于舌板112的两侧。例如，第一端子组12的端子121的接触段121a露出于舌板112的顶面1121，第二端子组13的端子131的接触段131a露出于舌板112的底面1122。示例性的，第一端子组12的端子121和第二端子组13的端子131可以至少部分嵌入舌板112，以使各端子(121、131)与舌板112的连接结构更为稳固可靠。其中，第一端子组12的端子121的尾段121c和第二端子组13的端子131的尾段131c相对绝缘主体11露出，例如相对座体111的底面1112露出。
一些实施例中，如图6A所示，绝缘主体11的内部设有安装空间113，安装空间113自舌板112延伸至座体111。安装空间113还可以自舌板112的第一侧面1123贯穿至第二侧面1124。结合参阅图4和图6A，接地片15位于安装空间113，以嵌设于绝缘主体11。接地片15的部分结构可以相对第一侧面1123和第二侧面1124凸出。如图7所示，接地片15位于第一端子组12与第二端子组13之间，用于提供屏蔽作用，以抑制第一端子组12与第二端子 组13之间的信号串扰。其中，绝缘主体11、第一端子组12、第二端子组13及接地片15可以采用嵌入成形(insert-molding)工艺形成一体化结构，也即为一体成型结构。
结合参阅图5和图7，一些实施例中，金属壳体14环绕舌板112，金属壳体14与舌板112之间形成插拔空间110。第一端子组12的各端子121的接触段121a露出于插拔空间110，第二端子组13的各端子131的接触段131a露出于插拔空间110。公端连接器2插接母端连接器1时，公端连接器2连接第一端子组12的端子121和第二端子组13的端子131。
在本实施例中，由于金属壳体14环绕舌板112、第一端子组12及第二端子组13设置，因此母端连接器1能够通过金属壳体14实现良好的电磁干扰(electromagnetic interference，EMI)功能和电磁兼容(electromagnetic compatibility，EMC)功能。
请结合参阅图6B以及图8，图8是图4所示母端连接器1的部分结构沿C-C处剖开的截面结构示意图。其中，图8所示截面经过母端连接器1的多个端子121的接触段121a和多个端子131的接触段131a。
一些实施例中，第一端子组12的多个端子121的接触段121a与第二端子组13的多个端子131的接触段131a对称设置。第一端子组12的部分端子121的横截面积大于另一部分端子121的横截面积。第一端子组12的部分端子121之间的间距相同，部分端子121之间的间距不同。接地片15的一侧相对舌板112的第一侧面1123凸出，接地片15的另一侧相对舌板112的第二侧面1124凸出。其中，结合参阅图5和图8，接地片15的两端也露出于插拔空间110，公端连接器2插接母端连接器1时，公端连接器2连接接地片15。
在本申请中，第一端子组12的多个端子121可以依据其传输的信号类型命名为不同的信号端子，各信号端子均包括依次连接的接触段、连接段及尾段，各段结构的位置分别对应于端子121的接触段121a、连接段121b及尾段121c的位置，后文中不再赘述。第二端子组13的多个端子131可以依据其传输的信号类型命名为不同的信号端子，各信号端子均包括依次连接的接触段、连接段及尾段，各段结构的位置分别对应于端子131的接触段131a、连接段131b及尾段131c的位置，后文中不再赘述。
一些实施例中，第一端子组12可以包括多个电源端子对122和多个高速端子对123。示例性的，第一端子组12可以包括两个电源端子对122和四个高速端子对123。电源端子对122包括电源端子1221和电源回流地端子1222。高速端子对123包括相邻的两个高速信号端子1231，高速端子对123可以为差分对。电源端子1221的接触段和电源回流地端子1222的接触段的横截面积大于高速信号端子1231的接触段的横截面积。
在本实施例中，母端连接器1通过设置多个电源端子对122提高通流能力，通过设置多个高速端子对123提高信号传输速率。并且，通过设置电源端子1221的接触段和电源回流地端子1222的接触段的横截面积大于高速信号端子1231的接触段的横截面积，使得电源端子1221的接触段和电源回流地端子1222的接触段具有较大的横截面积，电源端子1221和电源回流地端子1222的阻抗较小，以获得更高的通流能力，同时，高速信号端子1231的接触段保持较小的横截面积，既可以避免增加母端连接器1的界面整体尺寸，也有利于确保高速信号具有较佳的高频性能，故而母端连接器1能够提高通流能力，还能够保持较小的结构尺寸和较好的高频性能，以满足大功率、小体积及高传输速率的需求。
一些实施例中，结合参阅图8和图6B，电源端子1221的连接段和电源回流地端子1222的连接段的横截面积大于高速信号端子1231的连接段的横截面积，电源端子1221的尾段和电源回流地端子1222的尾段的横截面积大于高速信号端子1231的尾段的横截面积。此时， 母端连接器1能够更好地满足大功率和高传输速率的需求。
示例性的，在电源端子1221、电源回流地端子1222及高速信号端子1231中，其连接段和尾段的横截面积与接触段的横截面积相等或相近，以确保母端连接器1的通流能力和高速传输性能。例如，连接段和尾段的横截面积可以相等，其与接触段的横截面积的比可以在0.9至1.1的范围内。示例性的，接触段的横截面积可以略大于连接段和尾段，以确保接触段与公端连接器2的端子的充分接触，使得公端连接器2与母端连接器1之间的连接关系更为可靠。
示例性的，电源端子1221的接触段的横截面呈矩形，其在第一方向X上的尺寸可以在0.8mm至1.45mm的范围内，在第三方向Z上的尺寸可以为0.25mm，例如可以为1.45mm×0.25mm；或者，电源端子1221的接触段的横截面在第一方向X上的尺寸可以在1.0mm至1.81mm的范围内，在第三方向Z上的尺寸可以为0.20mm。在本实施例中，电源端子1221的通流能力可达15A，以更好地满足大功率需求。
其中，电源回流地端子1222的接触段的横截面形状及尺寸与电源端子1221的接触段相同。其中，高速信号端子1231的接触段的横截面呈矩形，其在第一方向X上的尺寸小于或等于0.25mm，在第二方向Y上的尺寸小于或等于0.12mm，例如可以为0.25mm×0.12mm。本申请实施例不对各端子的横截面的具体尺寸做严格限定。
一些实施例中，结合参阅图8和图6B，在第一端子组12中，电源端子1221的接触段和电源回流地端子1222的接触段的横截面积可以大于其他端子121的接触段121a的横截面积，以在确保母端连接器1的通流能力的情况下，控制界面整体尺寸，使得母端连接器1同时满足小体积的需求。
示例性的，第一端子组12中，电源端子1221和电源回流地端子1222以外的其他端子121的接触段121a的横截面的形状和尺寸可以是一致的。
其中，在第一端子组12中，电源端子1221的连接段和电源回流地端子1222的连接段的横截面积也可以大于其他端子121的连接段121b的横截面积，电源端子1221的尾段和电源回流地端子1222的尾段的横截面积也可以大于其他端子121的尾段121c的横截面积。
一些实施例中，如图8所示，电源端子1221的接触段与相邻端子121的接触段121a形成第一间距，高速信号端子1231的接触段与相邻端子121的接触段121a形成第二间距，第一间距大于第二间距。其中，在端子组中，相邻的两个端子彼此间隔设置，端子旁形成间隙，该间隙的宽度即为两个相邻端子之间的间距。在本实施例中，电源端子1221的接触段旁的间隙宽度大于高速信号端子1231的接触段旁的间隙宽度。
可以理解的，功率P＝电流I×电压V，母端连接器1为满足大功率需求，电源端子1221需要加载较高的电压。在本实施例中，电源端子1221的接触段与相邻端子121的接触段121a的间距较大，能够使电源端子1221与相邻端子121之间的爬电距离足够大，以避免电源端子1221上的电压大而导致的击穿现象造成母端连接器1的功能失效，使得母端连接器1的可靠性较高。同时，高速信号端子1231上无需加载高电压，高速信号端子1231的接触段与相邻端子121的接触段121a的间距较小，有利于使母端连接器1的界面尺寸较小。故而，母端连接器1的可靠性较高且体积较小。
例性的，若母端连接器1需要满足720W的传输功率，在电源端子1221能够实现15A通流能力的情况下，需要加载48V的电压，电源端子1221的接触段与邻近端子121的接触段121a的间距可以设置为0.85mm，以具有足够的爬电距离。其他端子121的两个相邻端子121间距可以设置为0.25mm。
一些实施例中，结合参阅图8和图6B，电源端子1221的连接段与相邻端子121的连接段121b的间距大于高速信号端子1231的连接段与相邻端子121的连接段121b的间距，电源端子1221的尾段与相邻端子121的尾段121c的间距大于高速信号端子1231的尾段与相邻端子121的尾段121c的间距。也即，电源端子1221与相邻端子121之间的间距大于高速信号端子1231与相邻端子121之间的间距，以确保母端连接器1的可靠性。换言之，电源端子1221旁的间隙宽度大于高速信号端子1231旁的间隙宽度。
一些实施例中，结合参阅图8和图6B，在第一端子组12中，电源端子1221的接触段与相邻端子121的接触段121a的间距可以大于其他端子121中两个相邻端子121的接触段121a的间距。电源端子1221的连接段与相邻端子121的连接段121b的间距可以大于其他端子121中两个相邻端子121的连接段121b的间距。电源端子1221的尾段与相邻端子121的尾段121c的间距可以大于其他端子121中两个相邻端子121的尾段121c的间距。换言之，电源端子1221旁的间隙宽度大于其他端子旁的间隙宽度。
一些实施例中，如图8所示，第一端子组12还可以包括多个隔离地端子124，高速端子对123的相邻端子121包括隔离地端子124。在本实施例中，高速端子对123的旁边设有隔离地端子124，以确保差分对自主的高频性能。其中，高速端子对123的两个相邻端子121中，可以一个是隔离地端子124，或者两个都是隔离地端子124。
一些实施例中，如图8所示，高速端子对123与电源端子1221之间设有隔离地端子124。此时，隔离地端子124用于避免或降低电源端子1221中的电源电流产生的磁场干扰高速端子对123中传输的高速信号。
一些实施例中，如图8所示，第一端子组12还包括低速端子对125，低速端子对125包括相邻设置的两个低速信号端子1251。应理解，在本实施例中，高速信号端子1231用于传输高速信号、低速信号端子1251用于传输低速信号，其中的高速和低速是相对的概念。示例性的，高速信号可以是传输速率等于或大于1Gbps的信号，低速信号可以是传输速率小于1Gbps的信号。
其中，低速端子对125与高速端子对123之间设有隔离地端子124，隔离地端子124用于隔离高速信号端子1231和低速信号端子1251，以降低或避免高速信号与低速信号之间的相互干扰。
一些实施例中，如图8所示，电源端子1221与隔离地端子124之间设有至少一个端子121，且与电源回流地端子1222之间设有多个端子121。在本实施例中，通过设置电源端子1221与隔离地端子121及电源回流地端子1222之间具有较大的间距，以避免母端连接器1的正负极太近而因异物或入液导致的腐蚀与安全问题，提高母端连接器1的可靠性。
一些实施例中，第一端子组12的端子信号序列与第二端子组13的端子信号序列相反。也即，第一端子组12的多个端子121和第二端子组13的多个端子131的传输信号以斜角对称的方式分布。也即，第一端子组12和第二端子组13的多个端子由左到右(也即由舌板112的一侧到另一侧)分别划分为第一个端子至第N个端子，第一端子组12的第一个端子与第二端子组13的第N个端子用于传输相同类型的信号，第一端子组12的第二个端子与第二端子组13的第N-1个端子用于传输相同类型的信号，第一端子组12的第三个端子与第二端子组13的第N-2个端子用于传输相同类型的信号……第一端子组12的第N-1个端子与第二端子组13的第二个端子用于传输相同类型的信号，第一端子组12的第N个端子与第二端子组13的第一个端子用于传输相同类型的信号。
在本实施例中，由于第一端子组12的多个端子121的接触段121a与第二端子组13的多个端子131的接触段131a对称设置，且第一端子组12的端子信号序列与第二端子组13的端子信号序列相反，使得母端连接器1能够允许公端连接器2正插和反插，以提高用户的使用体验。

一些实施例中，第三端子组22可以包括多个电源端子对222和多个高速端子对223。示例性的，第三端子组22可以包括两个电源端子对222和四个高速端子对223。电源端子对222包括电源端子2221和电源回流地端子2222。高速端子对223包括相邻的两个高速信号端子2231，高速端子对223可以为差分对。电源端子2221和电源回流地端子2222的抵接段的横截面积大于高速信号端子2231的抵接段的横截面积。
在本实施例中，公端连接器2通过设置多个电源端子对122提高通流能力，通过设置多个高速端子对123提高信号传输速率。并且，通过电源端子1221和电源回流地端子1222的抵接段的横截面积大于高速信号端子1231的抵接段的横截面积，使电源端子1221和电源回流地端子1222的抵接段具有较大的横截面积，电源端子1221和电源回流地端子1222的阻抗较小，以获得更高的通流能力，同时，高速信号端子1231保持较小的横截面积，既可以避免增加公端连接器2的界面整体尺寸，也有利于确保高速信号具有较佳的高频性能，故而公端连接器2能够提高通流能力，还能够保持较小的结构尺寸和较好的高频性能，以满足大功率、小体积及高传输速率的需求。
一些实施例中，电源端子2221和电源回流地端子2222的连接段的横截面积大于高速信号端子2231的连接段的横截面积，电源端子2221和电源回流地端子2222的尾段的横截面积大于高速信号端子2231的尾段的横截面积。此时，公端连接器2能够更好地满足大功率和高传输速率的需求。
示例性的，在电源端子2121、电源回流地端子2122及高速信号端子2131中，其连接段和尾段的横截面积与抵接段的横截面积相等或相近，以确保公端连接器2的通流能力和高速传输性能。示例性的，电源端子2221的抵接段的横截面呈矩形，其在第一方向X上的尺寸可以在0.8mm至1.40mm的范围内，在第三方向Z上的尺寸可以为0.25mm，例如可以为1.40mm×0.25mm；或者，电源端子2221的抵接段的横截面在第一方向X上的尺寸可以在1.0mm至1.81mm的范围内，在第三方向Z上的尺寸可以为0.20mm。在本实施例中，电源端子2221的通流能力可达15A，以更好地满足大功率需求。
其中，电源回流地端子2222的抵接段的横截面形状及尺寸与电源端子2221的抵接段相同。其中，高速信号端子2231的抵接段的横截面呈矩形，其在第一方向X上的尺寸小于或等于0.25mm，在第二方向Y上的尺寸小于或等于0.25mm，例如可以为0.20mm×0.20mm。本申请实施例不对各端子的横截面的具体尺寸做严格限定。
一些实施例中，结合参阅图24和图25，在第三端子组22中，电源端子2221和电源回流地端子2222的抵接段的横截面积可以大于其他端子221的抵接段的横截面积，以在确保公端连接器2的通流能力的情况下，控制界面整体尺寸，使得公端连接器2同时满足小体积的需求。示例性的，第三端子组22中，电源端子2221和电源回流地端子2222以外的其他端子221的抵接段的横截面的形状和尺寸可以是一致的。
其中，在第三端子组22中，电源端子2221和电源回流地端子2222的连接段的横截面积也可以大于其他端子221的连接段的横截面积，电源端子2221和电源回流地端子2222的尾段的横截面积也可以大于其他端子221的尾段的横截面积。
一些实施例中，结合参阅图24和图25，电源端子2221的抵接段与相邻端子221的抵接段形成第一间距，高速信号端子2231的抵接段与相邻端子221的抵接段形成第二间距，第一间距大于第二间距。可以理解的，功率P＝电流I×电压V，公端连接器2为满足大功率需求，电源端子2221需要加载较高的电压。在本实施例中，电源端子2221的抵接段与相邻端子221的抵接段的间距较大，能够使电源端子2221与相邻端子221之间的爬电距离足够大，以避免 电源端子2221上的电压大而导致的击穿现象造成公端连接器2的功能失效，使得公端连接器2的可靠性较高。同时，高速信号端子2231上无需加载高电压，高速信号端子2231的抵接段与相邻端子221的抵接段的间距较小，有利于使公端连接器2的界面尺寸较小。故而，公端连接器2的可靠性较高且体积较小。
例性的，若公端连接器2需要满足720W的传输功率，在电源端子2221能够实现15A通流能力的情况下，需要加载48V的电压，电源端子2221的抵接段与邻近端子221的抵接段的间距可以设置为0.90mm，以具有足够的爬电距离。其他端子221的两个相邻端子221的间距可以设置为0.30mm。
一些实施例中，电源端子2221的连接段与相邻端子221的连接段的间距大于高速信号端子2231的连接段与相邻端子221的连接段的间距，电源端子2221的尾段与相邻端子221的尾段的间距大于高速信号端子2231的尾段与相邻端子221的尾段的间距。也即，电源端子2221与相邻端子221之间的间距大于高速信号端子2231与相邻端子221之间的间距，以确保公端连接器2的可靠性。
一些实施例中，结合参阅图24和图25，在第三端子组22中，电源端子2221的抵接段与相邻端子221的抵接段的间距可以大于其他端子221中两个相邻端子221的抵接段的间距。电源端子2221的连接段与相邻端子221的连接段的间距可以大于其他端子221中两个相邻端子221的连接段的间距。电源端子2221的尾段与相邻端子221的尾段的间距可以大于其他端子221中两个相邻端子221的尾段的间距。
一些实施例中，如图25所示，第三端子组22还可以包括多个隔离地端子224，高速端子对223的相邻端子221包括隔离地端子224。在本实施例中，高速端子对223的旁边设有隔离地端子224，以确保差分对自主的高频性能。其中，高速端子对223的两个相邻端子221中，可以一个是隔离地端子224，或者两个都是隔离地端子224。
一些实施例中，如图25所示，高速端子对223与电源端子2221之间设有隔离地端子224。此时，隔离地端子224用于避免或降低电源端子2221中的电源电流产生的磁场干扰高速端子对223中传输的高速信号。
一些实施例中，如图25所示，第三端子组22还包括低速端子对225，低速端子对225包括相邻设置的两个低速信号端子2251。应理解，在本实施例中，高速信号端子2231用于传输高速信号、低速信号端子2251用于传输低速信号，其中的高速和低速是相对的概念。示例性的，高速信号可以是传输速率等于或大于1Gbps的信号，低速信号可以是传输速率小于1Gbps的信号。
其中，低速端子对225与高速端子对223之间设有隔离地端子224，隔离地端子224用于隔离低速端子对225与高速端子对223，以降低或避免高速信号与低速信号之间的相互干扰。
一些实施例中，如图25所示，电源端子2221与隔离地端子224之间设有至少一个端子221，且与电源回流地端子2222之间设有多个端子221。在本实施例中，通过设置电源端子2221与隔离地端子224及电源回流地端子2222之间具有较大的间距，以避免公端连接器2的正负极太近而因异物或入液导致的腐蚀与安全问题，提高公端连接器2的可靠性。
一些实施例中，第三端子组22的端子信号序列与第四端子组23的端子信号序列相反。也即，第三端子组22的多个端子221和第四端子组23的多个端子231的传输信号以斜角对称的方式分布。
在本实施例中，由于第三端子组22的多个端子221的抵接段221a与第四端子组23的多 个端子231的抵接段231a对称设置，且第三端子组22的端子信号序列与第四端子组23的端子信号序列相反，使得公端连接器2能够通过正插或反插的方式插接母端连接器1，以提高用户的使用体验。
其中，第三端子组22的端子221和第四端子组23的端子231数量与第一端子组12的端子121数量相同。第三端子组22的端子信号序列可以参阅第一端子组12的端子信号序列，第四端子组23的端子信号序列可以参阅第二端子组13的端子信号序列。例如，第三端子组22的端子221数量为22个，第三端子组22的端子信号序列为：电源回流地端子、高速端子对、隔离地端子、高速端子对、隔离地端子、第一端子、电源端子、配置端子、低速端子对、第二端子、电源端子、辅助端子、隔离地端子、高速端子对、隔离地端子、高速端子对及电源回流地端子。第一端子用于传输低速信号，配置端子用于插拔检测、供电协商、接口配置等，低速端子对包括相邻的两个低速信号端子，第二端子用于传输电源或低速信号，辅助端子用于高速链路初始化、HDCP握手、能力获取、音频回传等。第三端子组22和第四端子组23的端子信号序列的其他实施例和细节，此处不再赘述。
在本申请中，通过对公端连接器2的第三端子组22的端子221和第四端子组23中的端子231的结构设计、信号序列设计，使得公端连接器2能够满足300W至720W的大功率需求，且能够满足80Gpbs至192Gpbs的高传输速率需求，以更好地适用于通信系统1000中。同时，公端连接器2可以实现正反插，有利于提高用户的插拔体验。
请参阅图25，一些实施例中，电源端子2221的抵接段的高度小于高速信号端子2231的抵接段的高度，电源回流地端子2222的抵接段的高度小于高速信号端子2231的抵接段的高度。可以理解的是，端子的正向力F＝dEbh 3/4L 3，h为厚度，L为长度，b为宽度，d是位移量，E是弹性系数。因此，端子的正向力与端子的宽度成正比、与端子的厚度成3次方比，电源端子2221的正向力会因端子增厚、增宽，而较相邻端子221的正向力明显增加，可能造成对附近端子221的影响。在本实施例中，通过使电源端子2221和电源回流地端子2222的抵接段的高度小于高速信号端子2231的抵接段的高度，使得电源端子2221和电源回流地端子2222的正向力降低，以与高速信号端子2231的正向力相等或相近，从而使得电源端子2221、电源回流地端子2222及高速信号端子2231的弹性性能相近，公端连接器2插接母端连接器1时，这些端子221均能够与母端连接器1稳定接触，以提高连接器组件10的连接可靠性。
示例性的，在连接器组件10满足720W功率的实施例中，电源端子2221和电源回流地端子2222的抵接段的高度相较高速信号端子2231的抵接段的高度，可以至少低0.05mm。
其中，一些实施例中，电源端子2221和电源回流地端子2222的抵接段的高度小于其他端子221的抵接段的高度，使得电源端子2221的正向力与公端连接器2的其他端子221的正向力接近，以提高公端连接器2的各端子与母端连接器1的连接可靠性。
请结合参阅图24和图25，一些实施例中，电源端子2221的抵接段还可以设有切割缝2223，切割缝2223延伸至电源端子2221的抵接段的末端。其中，电源端子2221的抵接段的末端是指抵接段远离连接段的端部。在本实施例中，通过切割电源端子2221的抵接段，能够进一步降低电源端子2221的正向力，使得电源端子2221的正向力与其他端子221的正向力更为接近，以提高公端连接器2的各端子221与母端连接器1的连接可靠性。同样的，电源回流地端子2222的抵接段还可以设有切割缝2224，切割缝2224延伸至电源回流地端子2222的抵接段的末端。
可以理解的是，在其他一些实施例中，电源端子2221的抵接段和电源回流地端子2222的抵接段也可以只通过调节高度(也即抵接段不设置切割缝)、或者只设置切割缝、 或者结合更多设计方式，以将电源端子2221的抵接段和电源回流地端子2222的抵接段的正向力调节至目标范围，本申请实施例对此不做严格限定。
请结合参阅图23和图26，图26是图21所示公端连接器2与电路板4连接的组装结构示意图。
一些实施例中，公端连接器2应用于线缆组件中时，线缆组件还包括电路板4和线缆，公端连接器2固定连接且电连接电路板4，公端连接器2还通过电路板4电连接线缆。具体的，电路板4设有多个焊盘41，多个焊盘41中包括用于传输电源信号、高速信号、接地信号和其他信号的焊盘。公端连接器2的第三端子组22和第四端子组23的各端子的尾段焊接电路板4上的多个焊盘41，以电连接电路板4。其中，公端连接器2的接地板26焊接电路板4上的用于传输接地信号的焊盘。电路板4还设有另一部分焊盘，这部分焊盘可以用于电连接线缆组件的线缆。
以下结合连接器组件10的内部结构示意图，对公端连接器2和母端连接器1的连接关系进行举例说明。
请参阅图27，图27是图3所示连接器组件10沿H-H处剖开的截面结构示意图。

在本申请中，通过设计第一端子组12的多个端子的接触段和第二端子组13的多个端子的接触段对称设置、且端子信号序列相反，第三端子组22的多个端子的抵接段和第四端子组23的多个端子的抵接段对称设置、且端子信号序列相反，使得公端连接器2与母端连接器1可以正插，也可以反插，连接器组件10实现正反插功能，能够提高用户的插拔体验。
连接器组件10通过设计各端子组(12、13、22、23)均包括多个电源端子对和高速端子对，以满足大功率和高传输速率的需求。在一些实施例中，连接器组件10的功率可达300W至720W范围，传输速率可达80Gpbs至192Gpbs。同时，连接器组件10还通过设置母端连接器1和公端连接器2的电源端子对的电源端子和电源回流地端子的横截面积大于其他端子的横截面积，使得电源端子对能够实现大功率传输，并且母端连接器1和公端连接器2的界面尺寸较小，有利于小型化，而高速端子对的高速信号端子保持较小的横截面积也有利于确保传输信号的高频性能。
此外，连接器组件10还通过设计各端子组(12、13、22、23)中的电源端子对、高速端子对、隔离地端子、低速端子对等端子的排布位置，以提高可靠性。
此外，连接器组件10还通过设计第三端子组22和第四端子组23的各端子的抵接段的高度和/或形状，使得各端子的正向力相等或相近，使得第三端子组22的各端子的抵接段能够稳定接触第一端子组12，第四端子组23的各端子的抵接段能够稳定接触第二端子组13，母端连接器1与公端连接器2的电连接关系稳定、可靠。
