本实施例中,每个导接件20包括两个导接端子20a,相应的,每个线缆2包括两个信号线路,两个导接端子20a分别与其对应的信号线路电连接。两个导接端子20a分别间隔嵌设 于限位块127,有效防止两个导接端子20a在使用过程中发生电连接。当然,在其他实施例中,每个导接件20还可以包括两个以上导接端子,除传送信号的导接端子还可以包括用于接地的导接端子,用于接地的导电端子与第一壳体电连接能进一步减小连接器组件的串扰影响,能支持112Gbps及更高速率的信号传输。

可以理解的是,屏蔽层2a的周面均与其朝向的屏蔽腔11的周壁电连接,从而信号从屏蔽腔11的周壁回流至线缆2时,位于屏蔽腔11周壁的信号分别传递至与其靠近的屏蔽层2a的第一电连接部和第二电连接部上,信号的回流路径更短,回路电感小,有效减小连接器组件100的串扰影响,能支持112Gbps及更高速率的信号传输。

然后,如图8和图24,将安装有第一金属片14a的第一传输板60a安装于第一壳体12。具体的,第一传输板60a背向第一金属片14a的一侧朝向第一壳体12安装于第一壳体12的凹槽122内,第一传输板60a的导接件20和部分线缆2设于第一屏蔽槽125中,导接件20的接触部21位于第一部分1251,且其远离连接部22的端部设于限位块147上,导接件20的连接部22和部分线缆2位于第二部分1252。线缆2远离导接件20的一端通过第一出线槽126伸出第一壳体12。
本实施例中,接触部21远离连接部22的端部可以部分嵌设于限位块147背向第一屏蔽槽125的表面,也可以设于限位块147背向第一屏蔽槽125的表面。限位块147一方面限位导接件20,避免导接件20在使用过程中变形,另一方面还能防止导接件20与第一屏蔽槽125的槽壁电连接,提高连接器组件的使用寿命和提高连接器组件的安全性能。
第一金属片14a盖于第一壳体12的多个第一屏蔽槽125的第二部分1252的槽口,第一金属片14a的两侧限位于与其对应的容纳槽123的限位缺口1231中,隔墙124上的固定柱1241贯穿第一金属片14a的通孔142,以限位第一金属片14a。第一金属片14a与第二屏蔽槽133形成多个屏蔽腔,第一传输板60a的传输件50位于金属壳体的屏蔽腔内,且第一传输板60a的线缆2的屏蔽层2a的第一电连接部和第一壳体12电连接,第二电连接部和第一金属片14a电连接。
可以理解的是,线缆2位于屏蔽腔的部分嵌设于第一屏蔽槽125内,以使屏蔽层2a朝向第一屏蔽槽125的槽壁的第一电连接部与槽壁贴接,第一金属片14a的导接部143抵持于屏蔽层2a背向第一屏蔽槽125的第二电连接部。从而信号从屏蔽腔的周壁回流至线缆2时,位于屏蔽腔的周壁的信号分别传递至与其靠近的屏蔽层2a的第一电连接部和第二电连接部上,信号的回流路径更短,回路电感小,有效减小连接器组件的串扰影响,能支持112Gbps及更高速率的信号传输。
接着,如图4和图24,将安装有第二金属片14b的第二传输板60b安装于第一金属片14a背向第一壳体12的一侧。具体的,第二金属片14b背向第二传输板60b的表面设于第一金属片14a上,贯穿第一金属片14a的固定柱1241收容于与其对应的定位槽1461中,从而将第二金属片14b限位在第一金属片14a上。
最后,请参阅图13和图24,将第二壳体13的第二安装面1310朝向第一壳体12安装于第一壳体12上,形成连接器组件100(图3)。具体的,第二壳体13的第二屏蔽槽133一一包覆于与其对应的第二传输板60b的导接件20和部分线缆2,并抵持于第二金属片14b,与第二金属片14b围设形成多个屏蔽腔,线缆2远离导接件20的一端通过第二出线槽135伸出 第二壳体13。
具体的,第二壳体13盖于第一壳体12上,第二壳体13的两侧固定连接于容纳槽123内。第二壳体13可以通过卡接或螺接等方式固定连接第一壳体12。部分第一屏蔽槽125露出第二壳体13,可以理解的是,第二壳体13不覆盖部分第一屏蔽槽125,以便于位于第一传输板60a上的导接件20通过该部分第一屏蔽槽125露出金属壳体10,以便于与外部相关器件电连接。
第二壳体13上的凸条1322卡持于第二金属片14b与其对应的卡槽140内,第二壳体13的固定柱1321贯穿第二金属片14b的通孔148,以定位第二壳体13和第二金属片14b,及固定第二金属片14b和第二壳体13。导接件20的接触部21通过第二壳体13的开口1333露出第二壳体13,第二金属片14b的平直段144覆盖第二屏蔽槽133的开口1333,第二传输板60b的传输件50位于金属壳体10的屏蔽腔内,且屏蔽层2a的第一电连接部和第二壳体13电连接,第二电连接部和第二金属片14b电连接。
可以理解的是,第二传输板60b的线缆2位于屏蔽腔的部分嵌设于第二屏蔽槽133内,以使屏蔽层2a朝向第二屏蔽槽133的槽壁的第一电连接部与槽壁贴接,第二金属片14b的导接部149抵持于屏蔽层2a背向第二屏蔽槽133的第二电连接部。从而信号从屏蔽腔的周壁回流至线缆2时,位于屏蔽腔的周壁的信号分别传递至与其靠近的屏蔽层2a的第一电连接部和第二电连接部上,信号的回流路径更短,回路电感小,有效减小连接器组件100的串扰影响,能支持112Gbps及更高速率的信号传输。
本实施例通过先将第一金属片14a安装于第一传输板60a,及将第二金属片14b安装于第二传输板60b之后再将第一金属片14a和第二传输板60b一起安装于第一壳体12,及第二金属片14b和第二传输板60b一起安装于第一壳体12,也就是说,本实施例通过将连接器组件100的不同元件模块化后再进行组装,能够有效提高连接器组件100的组装效率,提高连接器组件100的生产效率,降低生产成本。
当然,在其他实施例的一种场景中,第一金属片不预先装于第一传输板,第二金属片不预先装于第二传输板,先将第一传输板装于第一壳体,接着在第一传输板背向第一壳体的一侧设置第一金属片,接着在第一金属片背向第一传输板的表面设置第二金属片,然后在第二金属片背向第一金属片的表面设置第二传输板,最后将第二壳体安装于第一壳体上。
在其他实施例的又一种场景中,提供金属壳体包括形成第一壳体和第二壳体,提供金属片,将金属片安装于第一传输板,将安装有金属片的第一传输板朝向第一壳体安装,将第二传输板安装于金属片背向第一传输板的一侧,然后将第二壳体安装于第一壳体上,以使第一传输板的传输件设于第一壳体和金属片形成的屏蔽腔中,及使第二传输板的传输件设于第二壳体和金属片形成的屏蔽腔中。
在其他实施例的再一种场景中,提供金属壳体包括形成第一壳体和第二壳体,将传输件或传输板设于第一壳体上,第二壳体盖合于第一壳体上,以使传输件安装于由第一壳体和第二壳体组成的屏蔽腔内,第一电连接部和第一壳体电连接,第二电连接部和第二壳体电连接。可以理解的,一个传输件对一个独立的屏蔽腔,传输件和屏蔽腔的数量相适应。
本申请通过先形成传输件50,再将传输件50安装于金属壳体10的屏蔽腔内,且至少两处电连接部均分别与其朝向的金属壳体10的部分电连接。也就是说,屏蔽层2a至少两处朝向不同的电连接部均分别与其朝向的屏蔽腔的周壁电连接,从而信号从屏蔽腔的周壁回流至线缆2时,位于屏蔽腔周壁的信号分别传递至与其靠近的屏蔽层2a的电连接部,相比于屏蔽腔的周壁仅与屏蔽层2a的一个电连接部电连接,信号的回流路径更短,回路电感小,有效减 小连接器组件100的串扰影响,能支持112Gbps及更高速率的信号传输。
以上,仅为本申请的部分实施例和实施方式,本申请的保护范围不局限于此,任何熟知本领域的技术人员在本申请揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本申请的保护范围之内。因此,本申请的保护范围应以权利要求的保护范围为准。
