Abstract

本发明涉及一种接触系统，接触系统包括弹簧和对应的相关印刷电路板表面，弹簧与该印刷电路板表面接触。被接触的印刷电路板表面是碳印刷电路板表面。根据本发明的接触系统，弹簧和碳印刷电路板表面之间的增强的接触阻抗进一步通过电和/或电子装置被补偿。弹簧的作用在于提供适合碳印刷电路板表面的弹簧力。

Description

接触系统
本发明涉及一种如权利要求1所述的接触系统。
目前，具体地讲，使用五种接触系统。在本申请中，给出可分离式接触系统与不可分离式接触系统之间的区别。
以锡弹簧(tin spring)为基础的接触系统是最节省成本的接触系统，锡弹簧与锡印刷电路板表面接触。
此外，已知以镀金弹簧为基础的接触系统，镀金弹簧与镍/金印刷电路板表面接触。
另外，已知以插头和插座形成的接触系统，该接触系统例如通过线缆结合到扬声器上。
另外，文档EP 1708218A2披露了一种具有至少一个接触弹簧和作用于接触弹簧的开关元件的接触系统，具有相对的接触器(opposing contact，与接触弹簧相关)的接触系统安装在印刷电路板上，且具有碳层。
最后，已知一种不可分离式接触系统，例如基于通过焊接制成的接触系统。
下文所涉及的金弹簧仅表示弹簧的端表面具有厚度厚达(例如)0.1μm的金层，而不是整个弹簧用金制成。然而，理论上，虽然通常因成本关系而不会这么做，不过当然也有可能制造出完全由金制成的弹簧。从技术上讲，也没有用实金制造弹簧的必要。
锡印刷电路板表面接触系统上的锡弹簧会由于磨擦腐蚀(frictioncorrosion)而发生故障，也就是说，使接触系统的功能失灵。
金电路板表面接触系统上的金弹簧对灰尘敏感。
具有用于弹簧接触的相对的接触器(具有碳层)的接触系统的传导性低于例如金层或者银层的传导性。
在仅需评估“数字”开关信号而不需要评估例如信号强度的开关程序的情况下，与接触系统的降低的传导性无关。
因此，这种接触系统可被用于例如家庭用具，而不会存在任何问题，其中，必须通过具有这种接触系统的选择开关的协助才能选择不同开关状态。
如果将上述三种接触系统与例如扬声器或例如收听器(hearing capsule)等结合，则由于这些接触系统的缺点，可能出现咔嚓噪声(clicking noise)或接触干扰或信号强度过低等现象。
本发明的目的在于在技术上改善这种接触系统，基于最初提及类型的接触系统，改善与这种接触系统相关的缺点，尤其避免在配合扬声器一起使用时，出现咔嚓噪声、干扰和信号强度过低等问题。此外，改善过后的接触系统成本应该低。
根据本发明，其目的通过如权利要求1所述的接触系统来实现。
根据本发明的接触系统，基于与印刷电路板表面接触的弹簧，相应地，接触系统具有作为印刷电路板表面的碳印刷电路板表面。此外，电和/或电子装置连接至接触系统，这样考虑到弹簧和碳印刷电路板表面之间的接触阻抗。最后，具有接触力的弹簧配入碳印刷电路板表面。
使用通过弹簧进行接触的碳印刷电路板表面，将接触阻抗从先前典型的20至200μOhm提高到2至10Ohm。通过示例，在收听器连接中，通过使用合适的电和/或电子装置来匹配电路以合适的方式补偿额外的阻抗。
由于在与弹簧结合时，弹簧的接触压力(contact pressure)与根据本发明的接触系统中的关系匹配，因此，根据本发明的接触系统可长期使用。
根据本发明的接触系统的进一步的优点在于，例如，当用碳印刷键盘印刷电路板时，同时也能印刷例如基于先前的生产系统必须使用不同材料按照不同制造步骤生产的收听容器接触器。因此，与例如使用锡弹簧和锡印刷电路板表面的接触系统相比，本发明的印刷电路板不需要额外成本。
另一优点在于，假设没有其它组件需要具有镍/金表面，则可能完全省掉进行接触需要的镍/金表面。
在接触系统不失坚实性的条件下，接触系统的寿命可达一百万或一百万以上的磨擦循环。与先前使用的具有锡弹簧和锡印刷电路板表面的接触系统相比，本发明相较之下使用寿命可延长大于1000倍。
根据本发明的接触系统，在制造过程中和使用时均相当抗尘。同时，根据经验，对于已知的接触系统，先前所使用的所有可能的金属组合均会产生咔嚓噪音，然而，在本申请中，根据本发明的接触系统，具体地讲，通过收听器应用的示例，并不存在咔嚓噪音。如上所述，唯一的区别在于较强的接触阻抗，然而，这一点也可通过上述的简单技术措施来补偿。
本发明的有利的改进在于从属权利要求的主题。
据此，用金弹簧作为弹簧，这样在接触系统进行接触时，能够达到最佳可能质量。
作为示例性实施例，描述了接触系统与安装在对应的相关印刷电路板上的收听器结合使用的情况，而在这种情况下，具体地讲，收听器设置有增强接触压力的金弹簧，当收听器被安装在印刷电路板上时，对对应的相关印刷电路板(在本申请中，印刷电路板由碳制成)表面施压，以这种方式进行接触。
