Description

电连接组件，将电缆的导体与金属织物电连接的方法
技术领域
本发明涉及一种电连接组件和一种将电缆的导体与金属织物电连接的方法。
背景技术
电连接组件可以例如在汽车的加热系统中使用。这样的加热系统可以包括垫状的柔性电加热元件，其具有用于电阻加热的金属织物。然而，在当前的解决方案中，难以与这些加热元件进行电连接。
发明内容
本发明的目的是要提供一种解决方案，其中电连接容易进行。
该目的通过一种电连接组件来实现，该电连接组件包括具有导体的电缆、与导体电接触的金属织物，该电连接组件还包括压接元件，其中，压接元件在导体和金属织物之间产生压力。
该目的进一步通过一种将电缆的导体与金属织物电连接的方法来实现，其中压接元件用于将导体和金属织物按压成电接触。
通过以下进一步的发展和有利的实施例，可以进一步改进根据本发明的解决方案，它们彼此独立并且可以根据需要任意组合。
为了使组装特别容易，可以在压接元件和金属织物之间放置绝缘织物。在这样的实施例中，例如，在进行电连接之前不必去除绝缘织物。
如果绝缘织物位于金属织物和压接元件之间，则可以在导体和金属织物之间存在直接的电连接。绝缘织物例如可以用作力传递元件，用于将按压力从压接元件传递到金属织物和导体之间的连接处。绝缘织物还可以帮助更好地分配力，避免可能造成损坏的局部力峰值。
在不同的解决方案中，绝缘织物可以位于导体和金属织物之间。在金属织物和压接元件之间可以存在电连接。压接元件然后可以在远离连接的不同位置处接触导体。
在另一发展中，至少在终端区域中不存在绝缘织物。在这样的实施例中，压接元件、金属织物和导体可以直接接触并且因此彼此电接触。这可能导致电连接组件的低电阻和高电导率。
金属织物和绝缘织物可以是电元件的一部分。电元件可以例如是电加热元件或柔性导电元件。金属织物可以是电元件的功能区域。
例如，金属织物和绝缘织物可以是电元件的接触部分的一部分。接触部分可以电连接到其他部分，例如加热部分。
电元件和金属织物可以具有两个或更多个接触区域，用于接触不同的电势。例如，一个接触区域可以适于接触正电压源，而第二接触区域可以适于接触地。
接触部分和/或接触区域可以是条形的，以便允许容易地插入压接部分中。
金属织物可以是机织织物，以易于生产。在替代方案中，金属织物可以是针织织物以实现高柔韧性。由纤维制成具有二维结构的织物的其他可能性，例如钩编、打结、毛毡，编织或其他技术，也是可能的。
金属织物尤其可以包括包含金属或由金属组成的丝线，以便能够导电。丝线可以例如被金属覆盖或涂覆。
在有利的实施例中，绝缘织物可以与金属织物机械地互连。这可以帮助增加稳定性。
例如，绝缘织物可以与金属织物交织。金属织物的一部分，例如丝线，可以被机织到绝缘织物的一部分中，反之亦然。
压接元件可以包围导体和/或金属织物。这可以帮助实现良好的按压连接。按压力可以指向内部或指向由周围的压接元件限定的区域。
压接元件可包括至少一个适于变形的压接部分。
压接元件可以通过变形获得压力。变形可以是塑性的和/或弹性的。优选地，压接元件在变形状态下产生作用在金属织物和/或导体上的按压力。
压接元件，特别是在压接部分处，至少在其变形之前的状态下可以具有C形的横截面，以便实现电连接。至少两个支腿可以从基部突出，特别是沿不同或相反的方向。支腿和基部可以限定用于金属织物和导体的容纳部。在变形期间，两个支腿的端部可以彼此接触，使得支腿和基部围绕金属织物。金属织物因此可以在变形状态下位于由压接元件限定的空间中。在变形状态下，压接元件可以围绕导体和金属织物形成闭合的环形结构。
根据本发明的用于电连接组件的套件可以包括处于未组装和/或未变形状态的电连接组件的元件。该套件可以例如包括具有导体、金属织物和/或压接元件的的电缆。
在该方法的有利实施例中，将金属织物和导体插入由压接元件形成的容纳部中，然后将压接元件围绕金属织物和导体压接。
有利地，首先将导体与金属织物连接，然后将两者的组合插入压接元件的容纳部中。例如，导体可以被放置在金属织物的旁边或之上。这样的实施例可以容易地以自动方式进行处理。
可以例如通过在金属织物和/或绝缘织物中切开狭缝来至少部分地切割金属织物和/或绝缘织物，以便使随后的变形更容易。
为了使插入更容易，在将金属织物插入到容纳部中之前，金属织物可以至少暂时地变形。例如，金属织物可以在插入导体之前或之后变形。该变形尤其可以包括在侧向方向上的滚动。金属织物然后可以形成主要为圆筒形的部分。
在替代方案中，首先将金属织物插入容纳部中，然后将导体插入。
附图说明
现在将使用有利的实施例并参考附图以示例性的方式且更详细地描述本发明。所描述的实施例仅仅是可能的构造，其中，然而，如上所述的各个特征可以彼此独立地提供或者可以省略。

在图1至4中，示出了将电缆10的导体11与金属织物20电连接的方法的四个步骤。
具体实施方式
金属织物20可以是电元件90(例如电加热元件91)的接触部分95的一部分。接触部分95可以包括两个接触区域96，一个用于接地连接，一个用于电压连接。每个接触区域96是条形的。
金属织物20位于绝缘织物30上。金属织物20和绝缘织物13可以例如通过交织而互连。金属织物20和绝缘织物可以以类似的方式被机织、针织或生产以实现二维织品或布。诸如导体33和加热线34的另外的导电线可以被机织到绝缘织物30中。
在图1中，已经执行了该方法的第一步。狭缝85已沿着纵向方向L切入绝缘织物30中，以便给予导电金属织物20的端部25可移动性。
在图2所示的第二步骤中，端部部分25向侧面变形，使得它们至少部分地形成基本圆形或圆筒形的横截面。
在图3所示的第三步骤中，将具有导体11的电缆10沿着与纵向方向L平行的插入方向I插入圆筒状的端部部分25，以使圆筒状的端部部分25沿着周向方向C围绕导体11。在部分25的外侧处，存在绝缘织物30。
图4示出了第四步骤，其中，将端部部分25插入压接元件50中，特别是插入由压接元件50形成的容纳部52中。随后，使压接元件50，特别是压接部分55变形，使得压接部分55围绕导体11、金属织物20和绝缘织物30。然后，压接部分55沿周向方向C闭合，并且特别是在导体11和金属织物20之间形成压配合，使得在两者之间实现可靠的电接触。
图5示出了通过图1至4的方法产生的电连接组件100的实施例的横截面。压接部分55包括两个实施为压接侧面56的支腿59，压接侧面56附接至基部57。压接部分55限定了一容积，电导体11、金属织物20和绝缘织物30位于其中。压接元件50通过绝缘织物30在导体11和金属织物20之间产生间接压配合。
导体11包括若干单个股线12，但是在另一示例中，导体11也可以仅包括一根粗线或股线12。类似地，金属织物20包括若干丝线23，其可以由金属制成或包括金属，例如为覆层形式的。
图6示出了另一可能的实施例。在该示例中，绝缘织物30已经部分地从电元件90移除。由此，可以实现压接元件50的压接部55、金属织物20和导体11之间的直接按压连接。绝缘织物30可以例如通过切割或加热来去除。
在图7中，示出了通过由图6中的部件形成的电连接组件100的横截面。可以看出，连接器11的股线12、金属织物20的丝线23和压接元件50直接电和机械接触。同样，压接部分55沿着周向方向C闭合。两个支腿59或压接侧面56已经朝向彼此弯曲，使得它们的端部接触。压接部分55的高力的塑性变形导致即使在主动变形步骤之后也仍然保持按压力并且此后产生恒定压力。
图8示出了为电加热元件91形式的整个电元件90。电元件90包括加热部分93，该加热部分93电连接至接触区域96，电缆10又附接至接触区域96。在接触区域96中，存在两条金属织物20，二者均位于绝缘织物13的顶部。金属织物20经由压接元件50附接到电缆10。这使得容易进行连接。
在图9中，示出了用于电连接组件100的套件。该套件包括具有导体11的电缆10，导体11包括若干单个股线12，具有两个压接部分55的压接元件50，以及附接到绝缘织物13上的金属织物20。如图10中所示的，电缆11的导体11可以缠绕有金属织物20并插入压接元件50中。
在图11中，示出了电连接组件100的另一实施例，其类似于由图9和图10的实施例产生的电连接组件。然而，在该实施例中，金属织物20、绝缘织物30和电缆10向远离压接元件50的同一侧突出。
