Description

与陶瓷密封夹爪的电连接和实现这种连接的方法
技术领域
本发明涉及用于导电陶瓷部件如密封夹爪的电连接，以及实现这种连接的方法。
背景技术
在包装技术中很久以来就已经知道了生产热塑性材料或涂覆有热塑性层的材料、例如塑料覆层的纸或纸板的包装。这些材料的固有优势在于它们可以通过施加在热塑性层相互之间的表面熔化而以方便的方式熔合在一起和密封在一起。通过这种方式，不仅可以保证通过折叠或其它方式所形成的包装可以保持其给定的结构，而且可以保证这些包装可形成液密密封，其可保护包装的内容物并防止这些内容物泄漏出来。这种类型的密封通常借助于不同类型的密封夹爪来实现。如果包装材料包括铝层，那么目前普遍采用所谓的感应密封，其中包装材料局部地承受快速变换的磁场，这会在铝层中引起热致电流，而该电流又会加热附近的热塑性层。如果包装材料不包括铝层，那么通常使用所谓的脉冲加热。根据这种方法，使用了所谓的加热夹爪，其由某些装置组成，待密封在一起的材料容纳在这些装置之间，并且装置在同时供热的过程中压缩该材料，从而导致被压缩且相互面对的塑料层的所需部分熔合在一起，形成紧密且机械上耐用的接合。通常出现的这类密封夹爪由设于支撑轨上的金属条或金属体构成，它们或者永久性地受热，或者在电流从中流过的各个单独的密封部位中受热。借助于在待密封材料的任一侧面上相互压在一起的两个受热密封夹爪，或者借助于一个密封夹爪和一个所谓的对靠夹爪都可执行这样的密封，其中对靠夹爪的目的只是构成加热夹爪的承靠物并冷却材料，从而使密封接缝快速稳定下来。在充填机中最普遍存在的密封夹爪由带有薄金属条的加热夹爪构成，其设置在钢轨上的绝缘陶瓷材料之上。在密封的场合中，以很大的压缩力来封闭密封夹爪，使得它们将待密封材料容纳在它们之间，之后使短电流脉冲通过上述瞬时被加热到升高温度的金属条。金属条中所产生的热量传递到包装材料上，导致相互面对的热塑性层熔合在一起。当已经产生了足量的热量时终止该电流脉冲，随后打开密封夹爪，使密封材料露出来。
如已在美国专利US-A-5682732和欧洲专利申请No.01108745.9中介绍的那样，近来已经看到研制了由加热轨构成的密封夹爪，其包括嵌入在由电绝缘陶瓷材料组成的主体中的导电陶瓷材料。对于这种类型的密封夹爪来说，使密封区域形成不同的几何形状具有多种可能性。另外，通过选择大致相同的线膨胀系数的材料可以降低与热相关的机械负荷，该负荷是由于所含组分的不同温度线膨胀系数引起的。
欧洲专利申请No.01108745.9描述了如何可以分别形成包含在密封夹爪中的导电和电绝缘的部件，从而便于制造和组装。该出版物还讨论了加热夹爪的冷却。
如在美国专利US-A-5682732中所述，通过使陶瓷表面金属化便可局部地提高该表面的导电能力。例如，这可以在那些通过传统的夹紧连接而将供电用的导电体连接到陶瓷上的位置处实现，在该夹紧连接中，导体被夹紧在被金属化的表面上。然而已经证明，在某些构造中，这种连接中的过渡电阻将具有与加热轨中的总电阻相同的数量级。另外已经证明，在连接位于潮湿环境中的某些构造中，连接会受到腐蚀损坏的影响。由于所采用的那些材料呈现出较高的电化学势，因此这种腐蚀情况甚至会恶化，这便导致该连接暴露在强大的电化学腐蚀下。
因此，在本领域中需要能够实现解决上述与供电用导电体和导电陶瓷之间的连接有关的问题。
发明概要
根据本发明，上述目的通过一种导言所述类型的连接来实现，该连接的特征是，导电体通过箔片而与导电陶瓷的一部分相结合，箔片使导电陶瓷的所述部分金属化，并使所述部分与导电体熔合在一起。
通过这种方式，已经形成了这样一种连接，其作为固定的整体连接到陶瓷的主体上，没有任何松散的部分需要被夹紧在正确的位置。形成为固定整体的电连接还提供了关于极大地降低了过渡电阻以及极大地降低了腐蚀敏感度的优点。在两个夹紧在一起的部件之间的连接中，不可避免会形成的狭窄间隙产生了用于所谓间隙腐蚀的理想空间。另外，腐蚀使间隙的开口增大，结果使过渡电阻甚至变得更大。而通过根据本发明的电连接则可避免这些问题。
从从属权项中可以清楚优选实施例。
根据一个优选实施例，电连接封装在可提供腐蚀防护的电绝缘材料中。通过这种方式，可以使可能形成电解质的液体保持远离连接，从而防止任何可能的电化学腐蚀破坏该连接。如果以一个整体件的形式形成该连接，那么可将绝缘材料压入到覆盖了该连接的罩盖中，而不存在渗透到接触面之间的风险。
有利的是，为了获得所需的电性能，第一导体可由选自银、铜、钛及其选择性组合的金属来生产。
有利的是，由于箔片由选自银、铜、钛及其选择性组合的金属来生产，因此便促进了结合。已经证明，这种箔片在关于陶瓷表面和导体金属表面的粘附和金属化方面具有正面的特性。
通过一种可在导电陶瓷部件如密封夹爪和导电体之间实现电连接的方法也可以达到上述目的，该方法包括步骤：在陶瓷表面上设置用于实现金属化表面的金属化箔片，提供与金属化箔片相接触的导电体，并且加热该金属化箔片，从而使陶瓷表面金属化并将其与导电体相结合。
通过这种方式，可以获得上述类型的电连接，其具备针对电连接本身的描述所提及的那些优点。
从从属权项中可以清楚根据本发明方法的优选实施例。
根据一个优选实施例，金属化箔片被加热，同时经历强大的局部真空，如同处于真空室等中一样。执行这个步骤是为了避免箔片材料与空气中的氧或其它成分发生反应的风险。这样实现的电连接是机械上坚固的，并可在高达600-700℃的较高工作温度下使用。
附图简介
下面将参照示意性附图来更加详细地介绍本发明，这些附图出于示例性的目的显示了本发明的一个当前最佳实施例。在附图中：
图1是密封夹爪的示意图；
图2显示了从侧面径直看去的根据一个优选实施例的密封夹爪；
图3显示了从正面径直看去的根据图2的密封夹爪；和
图4以透视图显示了图2和3所示的密封夹爪的一端。
一个优选实施例的详细描述
如图1中示意性显示，密封夹爪包括例如由铝制成的主体1，其中具有两个制冷剂可连续地或间歇地从中流过的冷却管道2a，2b。
在主体1中还设有陶瓷杆件3a，3b，4a，4b，它们沿着密封夹爪的纵向方向A(见图1和图3)在主体1的凹槽5a，5b中延伸。这些陶瓷杆件由电绝缘的陶瓷3a，3b以及导电陶瓷4a，4b构成，通过绝缘陶瓷3a，3b便可使导电陶瓷4a，4b与密封夹爪中的其余部件及其周围环境电绝缘。
图1还示意性地显示了狭长的凹口6，其在于充填机中进行密封接合时用来接受刀具。
图2-4显示了一个优选实施例，其中电绝缘陶瓷材料的整体件3带有两根导电陶瓷材料的狭长杆件4a，4b。例如，电绝缘材料可采用二氧化锆(ZrO2)和碳化硅(SiC)的混合物，而导电材料可采用硼化钛(TiB2)和碳化硅(SiC)的混合物。在绝缘材料中，ZrO2构成了10到50％体积、优选20到40％体积、最好约为30％体积的数量级。在导电材料中，TiB2构成了20到60％体积、优选35到55％体积、最好约为45％体积的数量级。
在末端处设置了导电材料的杆件4a，4b以便与电流源相连，借此可将电流提供给杆件4a，4b以加热杆件。该连接(见图4)包括两块银或银合金的板片7a，7b、夹紧套筒8以及一个更坚固的第二导电体11，其中夹紧套筒8通过螺钉9而夹紧在下方插入件10上，从而机械式地减轻电流连接的负荷，而银片7a，7b硬钎焊到第二导电体11上，并且第二导电体11设置用来与上述电流源相连。第二导电体11由银合金或其它一些低电阻率的金属制成，如镀银的铜等。夹紧套筒8和下方插入件10由电绝缘的聚合物材料制成，例如不同的塑料、硅等。另外，这类材料还呈现出一定的挠性，因此其可在不破坏接触的情况下吸收该连接中的某些运动。
为了保证接触片7a，7b与陶瓷4a，4b之间的接触电阻尽可能地小，在那些银片7a，7b将要与陶瓷材料4a，4b相连的位置点处使陶瓷材料4a，4b金属化，或者镀上金属。这种金属镀大约在700-800℃、强真空(约10-6毫巴)下进行，以避免与氧发生反应。这种金属镀通过薄的箔片形银/铜/钛基焊料12来进行。
在这种金属镀操作中，由于接触片7a，7b保持在陶瓷材料4a，4b的连接面上，因此可将接触片7a，7b与镀面钎焊或焊接在一起，从而形成具有整件制品式的连接。所选的焊料12具有良好的针对陶瓷表面的润湿能力，以及良好的贴靠在接触片7a，7b上的粘附能力。
通过以这种方式生产包含有陶瓷杆件4a，4b、接触片7a，7b以及焊料12的电连接，并且其中焊料12使陶瓷表面金属化且将接触片7a，7b焊接到陶瓷表面上，就可以实现一种完全的整体部件，之后可保护该整体部件免受潮湿和其它可能会增大腐蚀破坏风险的因素的影响。
例如，为了防止湿气渗入和导致腐蚀破坏，可在夹紧套筒8之下的空间内提供硅、油脂或其它绝缘材料。由于在导电体7a，7b和陶瓷杆件4a，4b的金属化表面之间不存在间隙等，因此不存在明显的该绝缘材料将影响电连接质量的风险。在采用夹紧连接的现有技术的设计和构造中，提供任何这种绝缘材料是不可能的，因为这会具有敞开的间隙且湿气会渗透至接触片之间，从而对连接质量产生负面影响的风险。最重要的是，这在使用具有相对较低机械强度的材料时会带来问题，并导致使用任何可用的作用力都无法将其夹紧在一起。
通过将陶瓷杆件4a，4b和第一导电体7a，7b之间的连接与第一导电体7a，7b和其它相连的连接件11之间的连接分离开来，就可以视其具体情况和条件而以优化方式来设计第一接触，并视其具体情况和条件来优化设计第二接触。由于已经通过根据本发明的方法直接在陶瓷金属化过程中实现了第一接触，因此其可经受相对较高的温度而不被破坏。因此，例如可在不会冒第一接触被破坏的风险的情况下对第二接触采用硬钎焊。
本领域的技术人员能够容易地意识到，在不脱离由所附权利要求限定的本发明范围的前提下，可对本文所介绍的本发明实施例进行各种修改。
例如，可以大量不同的方式来设计出包围了该连接的罩盖，只要其能以足够大的程度覆盖该连接，并将防蚀性材料保持在该连接的周围即可。
另外，可以构思出陶瓷所含组分的其它浓度。还可以构思出采用具有相应电性能的其它陶瓷材料。
