Description

一种屏蔽簧片和具有该屏蔽簧片的矩形连接器 技术领域
本发明涉及连接器技术领域，具体涉及一种屏蔽簧片和具有该屏蔽簧片的矩形连接器。
背景技术
屏蔽型矩阵式连接器是基于法拉第笼原理，利用分别与线缆外侧包覆屏蔽编织层连通的插头和插座外壳体的均匀和近似零间隙的插合连接，实现位于连接器插头和插座上线缆的整个线束导电连续性和其形成屏蔽体的电磁屏蔽性能；其中，线缆与连接器插头或插座的导电连续性可以采用常规具有360度屏蔽导通的功能组件来实现。
高密度插芯的矩阵式连接器主要用于自动化、机器人和轨道交通行业；屏蔽型矩阵式连接器常用于飞机线缆布线中，但是被公开的比较少；医疗器械中涉及的大功率设备中常用的屏蔽型矩阵式连接器的电气结构比较复杂，成本相对较高。
穿板式安装是矩阵式连接器安装结构的一种常规安装方式，如图1所示，连接器插座2采用螺钉紧固安装于面板1上；屏蔽簧片21设置于连接器插座2和连接器插头的插合缝隙之间，通过在其短脚处配置具有导通功能的背胶或者用于铆钉固定连接的通孔，将其固定在连接器插座2的侧面周面。
连接器插头与连接器插座2的插合过程中，连接器插头壳体10的内侧面与固定于连接器插座2外侧的屏蔽簧片21形成动态的弹性接触，屏蔽簧片21的凸起部分211受到来自连接器插头壳体1内侧面101的挤压，屏蔽簧片21的凸起211受压后，其自由端自由伸长，长脚端沿着连接器插座2的侧面相对滑动，屏蔽簧片21在连接器壳和座之间与其形成有效接触连接，从而实现了连接器插头壳体1、屏蔽簧片21和连接器插座2的电气连通。
屏蔽簧片21常采用特殊合金铍铜箔材经冲压成型，其金属材质具有一定的屈服极限。在实际使用中，连接器插头壳体10与连接器插座2的不对正插合，一方 面容易引起其背胶固定型屏蔽簧片脱离其黏附体，即连接器插座2；另一方面，对于铆钉固定类型，容易引起在连接器插座2的单侧的屏蔽簧片21上长期疲劳的过量压缩，导致屏蔽簧片21的塑性变形；此时，在连接器插头和连接器插座插合连接中，无法再利用屏蔽弹簧的压缩接触性能实现连接器插头和插座的壳体导电连续性和电磁屏蔽性能。

具体实施方式
下面结合附图和具体实施例对本发明进行详细说明。
如图1，为现有矩形连接器的结构示意图，连接器插座2采用螺钉紧固安装于面板1上，屏蔽簧片Ⅰ21设置于连接器插座2和连接器插头的插合缝隙之间，通过在其短脚处配置具有导通功能的背胶或者用于铆钉固定连接的通孔，将其固定在连接器插座2的侧面周面。
连接器插头与连接器插座2的插合过程中，连接器插头壳体10的内侧面与固定于连接器插座2外侧的屏蔽簧片Ⅰ21形成动态的弹性接触，屏蔽簧片Ⅰ21的凸起部分211受到来自连接器插头壳体1内侧面101的挤压，屏蔽簧片Ⅰ21的凸起211受压后，其自由端自由伸长，长脚端沿着连接器插座2的侧面相对滑动，屏蔽簧片Ⅰ21在连接器壳和座之间与其形成有效接触连接，从而实现了连接器插头壳体1、屏蔽簧片Ⅰ21和连接器插座2的电气连通。
屏蔽簧片Ⅰ21常采用特殊合金铍铜箔材经冲压成型，其金属材质具有一定的屈服极限。在实际使用中，连接器插头壳体10与连接器插座2的不对正插合，一方面容易引起其背胶固定型屏蔽簧片脱离其黏附体，即连接器插座2；另一方面，对于铆钉固定类型，容易引起在连接器插座2的单侧的屏蔽簧片Ⅰ21上长期疲劳的过量压缩，导致屏蔽簧片Ⅰ21的塑性变形，此时，在连接器插头和连接器插座插合连接中，无法再利用屏蔽簧片Ⅰ21的压缩接触性能实现连接器插头和插座的壳体导电连续性和电磁屏蔽性能。
为了解决该问题，本发明提供了一种屏蔽簧片Ⅱ20，将其设置于连接器插座与导通板之间的间隙，如图2，该屏蔽簧片Ⅱ20为矩形环，其2个长边部24和2个短边部22上设置有同向紧密排列的弓形凸起弹性部，弓形凸起弹性部按一字型等间距的排布在长边部和短边部的表面。
屏蔽簧片Ⅱ20固定在导通板17上，导通板17的上端面的外侧设置有周向的 沉槽171，屏蔽簧片Ⅱ20可对正放置在沉槽171上；屏蔽簧片Ⅱ20的矩形环上设置有通孔，可以采用销钉172通过通孔，将屏蔽簧片Ⅱ20固定于导通板17上。
导通板17上设置有装配螺钉的通孔173，连接器插头壳体内侧设有沉台101，沉台上设置有螺纹孔。屏蔽簧片Ⅱ20的矩环形内角设置有避让槽，如图5，装配有屏蔽簧片Ⅱ20的导通板17可采用组合螺钉19，穿过避让槽，将其固定于连接器插头壳体10内侧沉台101上。
导通板17和连接器插头壳体10是由弱磁材料经过特殊工艺加工制成，组合螺钉19由螺钉、弹性垫圈和垫片组成，组合螺钉19可依靠其弹性垫圈的弹性实现导通板17和连接器插头壳体10的可靠紧固和有效的导电连续性。
如图3、4，屏蔽型矩阵式连接器采用ITT矩阵式阳性插芯12和阴性插芯3；阳性插芯12的两边设置有通孔；导通板17上设置有螺纹孔；阳性插芯12从上插入导通板17的通孔后，可通过螺钉将阳性插芯12锁紧在导通板17上。
面板上设有可插合阴性插芯3的通孔，阴性插芯3从面板后侧插合于面板，连接器插座2的内侧设有沉槽171，沉槽171上设有通孔；面板1上设有对应的通孔；连接器插座2从面板1的外侧，对正通孔，与面板1贴合放置，通过螺钉29将连接器插座2和阴性插芯3固定于位于连接器插座2和阴性插芯3之间的面板1上。
具体应用中，如图3、4、5，连接器插座2为固定插合部，连接器插头为活动部，连接器插头的壳体10与连接器插座2对正后插合后止于面板1，可通过旋止设置位于阳性插芯12上的锁紧旋钮15来实现阳性插芯12和阴性插芯3的相对轴向和径向定位，从而实现连接器插头和连接器插座2的插合连接。
依靠黏贴于连接器插头壳体10的阳极插芯12的锁紧定位后，在与阳性插芯12固连的连接器插头的外壳10和与用于固定连接器插座2的面板1的插合方向之间必然存在间隙，同时，在与阴性插芯3固连的连接器插座2和与用于固定连接器插头于壳体10的导通板17的插合方向之间必然也存在间隙。
本发明将屏蔽簧片Ⅱ20设置于连接器插座2和导通板17之间的插合间隙内，可有效保证连接器插头的壳体10和面板的有效导电连通性，即使在由于连接器插头和插座不对正插合或疲劳过载插合引起位于连接器插头壳体10内侧与连接器插座内侧周向的屏蔽簧片Ⅱ2局部弹性连接失效的时候，轴向的屏蔽簧片Ⅱ20的布置可用于弥补合替代实现其连接器插头壳体10和面板1之间的有效导电连续性，最终实现其与连接器插头和连接器插座相连接屏蔽线缆的整体线束系统的整体屏蔽 功能。
如图4、6，连接器插头壳体10的背面设有用于穿入连接器阳极插芯12锁紧螺杆的通孔，锁紧使用标识18对正黏贴于通孔的凸台外圆面，使用标识18上标识有锁紧锁紧旋钮15锁紧阳性插芯12和阴性插芯3的参考标识，旋向箭头181和锁止线182。
上述的对实施例的描述是为便于该技术领域的普通技术人员能理解和使用发明。熟悉本领域技术的人员显然可以容易地对这些实施例做出各种修改，并把在此说明的一般原理应用到其他实施例中而不必经过创造性的劳动。因此，本发明不限于上述实施例，本领域技术人员根据本发明的揭示，不脱离本发明范畴所做出的改进和修改都应该在本发明的保护范围之内。
