Description

轴向上弹性的压入接触销
技术领域
本发明涉及一种轴向上弹性的压入接触销，其具有金属体，金属体具有压入弹簧和销状的部段，其中，该销状的部段至少局部地由可导电的弹性元件包围，并且其中，弹性元件超越销状的部段的自由的末端部段延伸。
背景技术
由德国的公开文件DE102006000959A1已知具有成形于两个末端部段上的压入弹簧的金属销，以便在两个相互对置设置的电路板之间建立电连接，所述压入弹簧压入两个电路板中。
当电路板中的一个电路板构造成薄片导体时，无法应用这样的压入销。在这种情况下通常使用同样被称作ZIF(Zero Insertion Force)连接器的零力式插接连接器，所述零力式插接连接器容纳并接触薄片导体的末端部段。然而，尤其在仅仅需要建立较少的电连接时，ZIF连接器成本相对高昂。
发明内容
于是要探寻可简单实现的且成本特别低廉的方案，以便在刚性的电路板和另一接触面之间、尤其是和薄片导体之间建立数个电连接。
该任务通过具有权利要求1的特征的轴向上弹性的压入接触销解决。
在第一末端部段上，压入接触销构造压入弹簧，该压入弹簧能够置入电路板中的金属化的孔内。对置的第二末端部段在轴向上弹性地，并且可导电地实施，从而所述第二末端部段可弹性地贴靠在接触面上并且在此产生一定的接触压力。
要么能够通过与压入接触销的金属体相连的弹性体来构造压入接触销的第二末端部段，要么能够通过例如螺旋弹簧形式的金属弹簧元件来构造压入接触销的第二末端部段。
附图说明
后文借助附图示出并进一步阐述本发明多个实施例。在各截面图中：
图1示出压入接触销的第一实施例，
图2示出压入接触销的第二实施例，
图3示出压入接触销的第三实施例，
图4示出第一压入接触销的应用示例，
图5示出第二压入接触销的应用示例，
图6示出第三压入接触销的应用示例，
图7示出第四压入接触销的应用示例，
图8示出第五压入接触销的应用示例。
具体实施方式
图1示出根据本发明实施的轴向上弹性的压入接触销1的第一实施例。所述压入接触销1由金属体10构成，该金属体的第一末端部段通过形成为小环圈的压入弹簧12构造。
所述金属体10的第二末端部段实施为销状的部段14。在所述第一末端部段和第二末端部段之间，所述金属体10具有横梁16。
销状的部段14由弹性体20包围，该弹性体完全围住销状的所述部段14并且优选地支撑在所述横梁16上。所述弹性体20在此尤其超出销状的所述部段14的自由的末端。
优选地以弹性体材料将销状的所述部段14注塑包封，因此制造所述弹性体20。在此有利的是，销状的所述部段14在其纵向方向上具有变化的、例如呈多个横截面加宽部形式的横截面宽度，借此得到所述金属体10与所述弹性体20之间的形锁合的连接。通过合适地选出的可导电的填充材料，所述弹性体20构造成整体上可良好导电。
图1示出的压入接触销1的应用示例在图4中示出。所述压入接触销1在此借助其压入弹簧12压入刚性的第一电路板40中的金属化的孔42内。
所述压入接触销1的对置的末端部段通过所述弹性体20的端面22构造，并且贴靠在构造成导电薄片的第二电路板50上。在此通过壳体面60的部段来支撑所述导电薄片50。
设定所述第一电路板40和第二电路板50之间的距离、或者说设定所述压入接触销1的轴向总长度，使得所述弹性体20在所述压入接触销1的轴向方向上弹性地受到一定程度的压缩，从而所述弹性体20的端面22以一定的接触压力贴靠在所述第二电路板50上的接触面上。
可以设想的是，金属化的所述孔42通过所述第一电路板40上的未示出的导体路径，与同样未示出的电结构元件或者电子结构元件相连。因此，通过所述压入弹簧12、金属体10和可导电的弹性体20，得到所述第一电路板40上的结构元件与所述第二电路板50上的接触面之间的导电连接。
所述导电薄片50例如可构造所述壳体面60下方的电容式接近传感机构的接触面，其中，附属的分析评估电子器件的结构元件可设置在所述第一电路板40上。
图2示出压入接触销2的第二实施例，其中所述弹性体20′的形状能够变化。所述弹性体20′在这里具有两个(或者同样多于两个的)臂24′或者甚至具有环行的、分别带有端面22′的圆环状盘，而不再像图1中的弹性体20那样具有单独的端面22。由图5可知，所述压入接触销2能够这样同时接触所述第二电路板50的多个位置。
图3示出轴向上弹性的压入接触销3的第三实施方案。在这里通过金属的弹簧元件构造所述弹性元件30并且专门构造为螺旋弹簧。
所述金属体10’的销状的部段14′可借此构造成简单的圆柱状销，并且不需要具有不同横截面宽度的部段。为了固定所述螺旋弹簧30，所述螺旋弹簧可与所述金属体10′的横梁16焊接或钎焊在一起。
图6示出类似于图4、图5工作的应用示例，其具有根据图3的压入接触销3。
图7示出压入接触销4的另一实施方案。该压入接触销4的销状的部段14″在其自由的末端折叠或者呈螺旋状地卷起，它借此构造了横截面加宽部18″，弹性体20″能够喷射在该横截面加宽部上或者按其它方式固定在该横截面加宽部上。
图8示出作为最后的实施例的压入接触销5，该压入接触销的销状的部段14″′具有冷杉树状的横截面加宽部18″′。所述弹性体20″′在这里形成为衬套状的单独部件，该单独部件与壳体基体62预装配。在将销状的所述部段14″′置入所述弹性体20″′时，冷杉树状的所述横截面加宽部18″′呈倒钩状地抓在所述弹性体20″′的内壁上。在将壳体面60装配到所述壳体基体62上时，同样使贴靠于所述壳体面60的第二电路板50压紧至所述弹性体20″′的端面22″′上。
