Abstract

本发明涉及一种适于同带有电接触器(31)的电源电连接的传感器。该传感器具有带第一电极(2)的第一绝缘基片(1),和带第二电极(6)的第二绝缘基片(7)。这些电极以彼此隔开的关系面对面设置而将隔片(4)夹在其间。第一切口部分穿过第一绝缘基片(1)和隔片(4)延伸,以在第二绝缘基片(7)上暴露一第一接触区(23)。这就允许电接触器(31)实现与第一接触区(23)的电连接,随后实现第一接触区(23)与第二电极(6)的导电连接。类似的接触机构可被设置在传感器的相反一侧。

Description

传感器连接机构
技术领域
本发明涉及可随意处理型用于定量分析例如血液中葡萄糖含量、pH值测量或诸如此类用的电化学传感器。更具体地说，本发明涉及电连接这种传感器至测量设备上用的机构。
背景技术
美国专利5,437,999公开了一种这类电化学传感器，其被与一电源电连接使用。该传感器由两决隔开的印刷电路板构成，每一印刷电路板在其一侧带有金属层，且被配置为使两金属层以隔开的关系相互面对。该金属层被进行光刻处理以限定构成样品池(cell)一部分的电极区。在该组件的一端，此电极基片被切开以提供沿横向分隔开的突起薄片，支承在金属层上面。该薄片被暴露的表面起着接触焊盘的作用，每一接触焊盘被电连接在相应电极上。该接触焊盘随后同连接电源的接触端啮合，并在传感器与电源之间提供电连接。
美国专利5,437,999的配置具有如下缺点，其基片要求具有显著的刚性，以保证满意和可靠的电接触。此外，就传感器是否满意地与电源连接而论，用户常常难于辨别。
在共同未决的申请PCT/AU96/00207，PCT/AU96/00365，PCT/AU96/00723和PCT/AU96/00724中，描述了许多种非常薄的电化学样品池(electrochemical cell)。每种样品池被限定在彼此隔开且面对面的一对电极之间，该电极被作为淀积在薄的惰性塑料膜(例如100μ厚度的PET聚酯薄膜)上的薄的金属镀层(例如溅射镀层)形成。两电极被一厚度例如500μm或更小的隔片彼此隔开。
美国专利5,437,999的连接装置对于我们共同未决的申请中讨论的这种极薄的传感器装置并不适用，由于其绝缘电极承载体的柔韧性不足。一般说来，需要这种可随意处理型传感器能由不熟练的用户简单、迅速、可靠及有效地与测量装置中的电源相连接。本发明的目的在于克服或者改进现有技术中的至少缺点之一，或者提供有效的供选择的比较方案。
发明描述
根据第一方面，本发明提供一种适于同带有第一接触器的电源电连接的传感器，该传感器包括：
一带有第一电极的第一绝缘基片和一带有第二电极的第二绝缘基片，并且上述电极以彼此隔开的关系面对面设置，
一第一切口部分，其穿过上述第一绝缘基片和一隔片延伸而使第二绝缘基片上暴露一第一接触区，以让第一接触器与设置在第二绝缘基片上的该第一接触区实现电连接，且此第一接触区与第二电极处于导电连接。
该第一接触区可被保持在距第一绝缘基片以一予定的深度。
根据第二方面，本发明提供一种根据第一方面的传感器，进一步包括一第二切口部分，其穿过上述第二绝缘基片和该(或另一)隔片延伸而使第一绝缘基片上暴露一第二接触区，以让第二接触器与设置在第一绝缘基片上的第二接触区实现电连接，且此第二接触区与第一电极处于导电连接。
该第二接触区可被保持在距第二绝缘基片以一予定的深度。
根据第三方面，本发明还提供一种检测系统，其包括根据第一或第二方面的传感器和一检测设备，该检测设备包括适于分别同第一和第二接触区实现电连接的第一接触器和/或第二接触器。
如在此使用的“包括”被用在范围广的意义上，也就是说在“包括”或“包含”的意义上。该术语并不是用在排他的意义上(“由……组成”或“由……构成”)。
在优选实施例中，该绝缘基片由柔性绝缘材料制成。第二电极和第一接触区由淀积在第一基片上的一体的金属层形成，而且更为优选的是通过溅射镀膜淀积其上。适合的金属包括但不局限于钯、金、铂、铱和银。碳也可以使用。该接触器最好是金属接触器，其被弹性偏置，以穿过第一切口部分伸展而与第二基片上的金属的第一接触区相接触。在非常优选的实施例中，该接触器适于同穿过第一绝缘基片和隔片延伸的切口部分掣子啮合。
采用本发明的连接器，其隔离层可提供附加的强度。因而使用柔性的材料可以构成刚性的连接器。这就能够利用较宽范围的各种材料。而且音响证实连接也可简单地由本发明提供，不象美国专利5,437,999中描述的连接器。

实施本发明的最佳方式
参见图1至3，其表示一电化学传感器的第一实施例。该传感器包括一约为25mm×5mm的聚酯隔片4，厚度100μ并带有直径3.4mm的圆孔8。圆孔8限定一圆柱形的样品池壁10。粘在隔片4一侧的是带有第一个钯镀层2的第一绝缘基片的聚酯片1。钯是在4与5毫巴之间的压力下在氩气氛中溅射镀在片1上的，以给出约100-1000厚度的均匀涂层。片1通过粘合剂3粘在隔片4上，并以其钯镀层2邻接隔片4和盖住孔8的一侧。
第二个绝缘基片7由带有第二个溅射的钯镀层6的聚酯片构成，通过接触粘合剂5以其钯镀层6粘附在隔片4另一侧并盖住孔8的相反一侧。因而限定一样品池，其具有圆柱形的侧壁10并以圆柱体一端为第一个钯金属电极2所封闭。圆柱体的另一端壁则是由钯形成的第二电极6。此组件在9处被切口，以为溶液进入该样品池及让空气逸出提供手段。
邻近20一端切出来的孔21贯穿第一绝缘层1和第一金属层2。在本实例中切口21是卵形。隔片4中相应的切口部分22与切口21对准。图3表示传感器1的侧视剖面，传感器被插入其上装有第一弹性接触器31和第二弹性接触器32的测量装置一部分30中形成的接收槽中。当传感器的一端20插入接收槽时，接触器31在绝缘层1的外表面上浮动并卡入由孔21和22形成的侧壁，以与金属层6上的第一接触区23啮合。第一接触区23乃是淀积在绝缘层7上的由其形成第二电极的同一金属层6的一部分，因而与样品池8的第二电极区处在导电耦合中。接触区23实际上在本实例中是由隔片4中切口20的直径限定的。
在图1所示的实施例中，比孔21进一步偏离边缘20的第二个圆形切口部分25，穿过第二个绝缘层7和第二个金属层6延伸。隔片4中的切口部分26(参见图2)同绝缘层7中的切口部分25相应及对准。再一次参见图3，在使用中传感器的结构是让第二个弹性偏置的接触器32穿过切口部分25及26限定的壁延伸，从而使弹性接触器32与在27处的金属层2啮合及进行电接触，因而与样品池8的第一电极2电接触。
弹性接触器31及32被安置在测量装置的槽30中，并且电连接在测量电路中。在使用中传感器以其边缘20导向被插入槽30中。第一弹性接触器31在传感器的端部范围上浮动，直至其碰到第一孔21及22从而与此开口掣子啮合并与金属层6上的第一接触区23进行电接触。传感器1在接收槽30中轻微的附带插入，将引起第二接触器32与第二孔25及26的掣子啮合并与金属层2的第二接触区27接触。
隔片4环绕两个孔设置并且确保，不论这些绝缘层的固有柔性如何和传感器如何地薄，均可以可靠的精度进行电接触。
本发明第二实施例表示在图5～7中，其中功能上与图1，2实施例的相应部分对应的部分以相应的数字加以区分。第二实施例与第一实施例之间的主要区别在于，第二实施例中的切口部分21，22是从传感器1的一侧边缘切出的，而切口部分25，26是从传感器1的相反一侧边缘切出的。在这种情况下，接触器31和32是沿横向隔开的，并且基本上同时卡入它们相应的切开口中。这些切开口被隔片4三边环绕，第四边被暴露在该传感器的相应边缘处。
虽然图5～7所示实施例中两开口处于距底端20相应距离处，但在其它实施例中它们也可沿纵向分隔开，如在所述第一实施例中的情况那样。这可保证仅当传感器被沿正确方向插入时才能接触，并保证正确的极性。
第三实施例示意表示在图8中。在这种情况下其开口采取从边缘20纵向延伸的槽21，25的形式。首选隔片4环绕图8中开口21及25的所有边缘延伸，但在不太优选的实施例中隔片4只沿槽21及25的三边延伸，在这种情况下无法获得掣子啮合，或者仅当接头从相反方向伸出时才能获得。然而其优点是该传感器的接触焊盘区以予定的尺寸距其相对面得以保持。如果所需要的这些槽可以长度不同并且与纵向分隔开的接头共同操作，那么带有两个接头的接触要求传感器正确取向地插入。
应当理解，该结构的材料和规格只是通过举例给出的，而且不同设计或结构的传感器均可以利用本发明。一、二或者更多个接头可由所示的机构提供。本发明当与传感器通过所述机构连接时可扩展到包括电源或测量装置。任何适当形式的接触器可与本发明的传感器一起使用。
