作为本实施例的一种改进方式，第一板体141远离第二板体142的一侧设有若干个缺口143。该缺口143用于第一绝缘件11注塑成型后，第一绝缘件11可以在该缺口143处形成阻挡部，使得屏蔽件14可以被限制在第一绝缘件11中。
请参阅8和图9，作为本实施例的一种改进方式，第二连接器20包括第二绝缘件21、固定于第二绝缘件21相对两侧的第二端子22、以及固定于第二绝缘件21的第二金属屏蔽壳23，第二绝缘件21包括第二底板211和围设于第二底板211边缘的第二围壁212，第一连接器10和第二连接器20嵌合时，第二围壁212嵌设于回字形凹槽101中。
作为本实施例的一种改进方式，所述第二金属屏蔽壳23设有两个，第二端子22设于第二围壁212相对的两侧，两个所述第二金属屏蔽壳23分别设于第二围壁212另外相对的两侧。每个第二金属屏蔽壳23包括第二顶板231、设于第二顶板231外边缘的第三侧板232、以及设于第二顶板231内边缘的第四侧板233，第二围壁212设有所述第二金属屏蔽壳23的两侧分别嵌设于第二顶板231、第三侧板232以及第四侧板233围合形成的凹槽中。
作为本实施例的一种改进方式，第一连接器10和第二连接器20嵌合时，第一端子12与所述第二端子22接触，第一金属屏蔽壳13和第二金属屏蔽壳23接触。
实施例二：
请参阅图10-11,本实施例中公开的多极连接器与实施例一中公开的多极连接器100不同的地方在于定位孔的个数和设置方式不同，具体体现在：本实施例中，定位孔201设有两个，两个定位孔201在屏蔽件202的延伸方向上间隔设置，如同实施例一中的设置方式，屏蔽件202将每个定位孔201分隔为位于屏蔽件202一侧的第一孔部203和位于屏蔽件201另一侧的第二孔部204。以该设计方式，通过设置两个定位孔201，使得屏蔽件202的定位更为精确。
需要说明的是，定位孔的个数不局限于实施例一中设置的一个，也不局限于实施例二中设置的两个，还可以是两个以上的其它个数，具体可以根据实际设置需要而定。
本实施例公开的多极连接器中其它部件的结构及部件之间的连接关系可以参照实施例一中公开的多极连接器100，在此不做赘述。
实施例三：
请参阅图12-13,本实施例中公开的多极连接器与实施例一中公开的多极电连接100不同的地方在于孔位机构的不同，具体体现在：本实施例中，定位孔301设有两个，两个定位孔301在屏蔽件302的延伸方向上间隔设置，其中一个定位孔位301于屏蔽件302的一侧，另一个定位孔301位于屏蔽件302的另一侧。
本实施例公开的多极连接器中其它部件的结构及部件之间的连接关系可以参照实施例一中公开的多极连接器100，在此不做赘述。
以上所述的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。
