Description

导电端子和连接器
技术领域
本发明涉及一种导电端子和包括该导电端子的连接器。
背景技术
在现有技术中,存在一种以夹持的方式与导体电连接的导电端子,通常,该导电端子包括两对弹性悬臂,每对弹性悬臂适于夹持一个导体,例如,一根导线。在现有技术中,为了能够可靠地夹持住导体,在导体被压入和夹持在一对弹性悬臂之间时,弹性悬臂会发生弹性变形。但是,在现有技术中,在将导体压入到一对弹性悬臂之间的过程中,弹性悬臂的自由端始终处于悬浮状态,即,弹性悬臂始终为悬臂梁结构,这导致当被夹持的导体的直径过大或者导电端子出现振动时,弹性悬臂很容易发生塑性变形。一旦弹性悬臂出现塑性变形,就会导致导电端子与导体之间的电接触不可靠或失效。
发明内容
本发明的一个目的旨在解决现有技术中存在的上述问题和缺陷的至少一个方面。

所述第二导体的直径小于所述第一导体的直径,当所述第二导体被夹持在所述一对第二弹性悬臂之间时,所述第二弹性悬臂的自由端与所述第二容纳室的内壁不接触。
根据本发明的另一个实例性的实施例,所述第一弹性支撑结构包括形成在所述第一弹性悬臂的自由端处的第一弯钩部;当所述第一导体被夹持在所述一对第一弹性悬臂之间时,所述第一弹性悬臂的自由端通过所述第一弯钩部被弹性地支撑在所述第一容纳室的内壁上。
根据本发明的另一个实例性的实施例,在所述第一容纳室的内壁上形成有第一弧形凸起,所述第一弧形凸起与所述一对第一弹性悬臂的自由端的端面相对。
根据本发明的另一个实例性的实施例,所述导电端子还包括一对第二弹性悬臂,用于夹持第二导体;所述一对第二弹性悬臂连接至所述主体部并容纳在所述主体部的一个第二容纳室中;在所述第二弹性悬臂或所述主体部上形成有第二弹性支撑结构,使得当所述第二导体被夹持在所述一对第二弹性悬臂之间时,所述第二弹性悬臂的自由端可通过所述第二弹性支撑结构被弹性地支撑在所述第二容纳室的内壁上。

根据本发明的另一个实例性的实施例,在所述第二容纳室的内壁上形成有第二弧形凸起,所述第二弧形凸起与所述一对第二弹性悬臂的自由端的端面相对。
根据本发明的另一个实例性的实施例,所述导电端子为通过冲切单片金属料板制成的单个金属端子或通过模制工艺制成的单个金属端子。
根据本发明的另一个实例性的实施例,所述一对第一弹性悬臂和所述一对第二弹性悬臂完全相同,并且对称地布置在所述导电端子上。
根据本发明的另一个方面,提供一种连接器,包括绝缘本体和容纳在所述绝缘本体中的前述导电端子。
在本发明的前述各个实例性的实施例中,在导电端子的弹性悬臂或主体部上形成有弹性支撑结构,当导体被夹持在一对弹性悬臂之间时,弹性悬臂的自由端可通过该弹性支撑结构被弹性地支撑在主体部上,使得一对弹性悬臂从悬臂梁结构转变为简支梁结构,从而能够有效地降低弹性悬臂发生塑性变形的风险。

下面通过实施例,并结合附图,对本发明的技术方案作进一步具体的说明。在说明书中,相同或相似的附图标号指示相同或相似的部件。下述参照附图对本发明实施方式的说明旨在对本发明的总体发明构思进行解释,而不应当理解为对本发明的一种限制。
另外,在下面的详细描述中,为便于解释,阐述了许多具体的细节以提供对本披露实施例的全面理解。然而明显地,一个或多个实施例在没有这些具体细节的情况下也可以被实施。在其他情况下,公知的结构和装置以图示的方式体现以简化附图。
根据本发明的一个总体构思,提供一种导电端子,包括:主体部;和一对第一弹性悬臂,用于夹持第一导体。所述一对第一弹性悬臂连接至所述主体部并容纳在所述主体部的一个第一容纳室中。在所述第一弹性悬臂或所述主体部上形成有第一弹性支撑结构,使得当所述第一导体被夹持在所述一对第一弹性悬臂之间时,所述第一弹性悬臂的自由端可通过所述第一弹性支撑结构被弹性地支撑在所述第一容纳室的内壁上。
第一实施例
图1至图3显示了根据本发明的第一实施例的导电端子和连接器,其中,图1显示根据本发明的第一实施例的连接器的立体示意图;图2显示图1所示的连接器的导电端子10的示意图,其中未显示被夹持的第一导体30;图3显示图1所示的连接器的导电端子10的示意图,其中显示了被夹持的第一导体30。
如图1所示,在图示的实施例中,连接器主要包括绝缘本体1和容纳在绝缘本体1中的导电端子10。
如图2和图3所示,在图示的实施例中,导电端子10包括主体部100和一对第一弹性悬臂110、110。一对第一弹性悬臂110、110用于夹持第一导体30。一对第一弹性悬臂110、110连接至主体部100并容纳在主体部100的一个第一容纳室101中。
如图2和图3所示,在图示的实施例中,在第一弹性悬臂110或主体部100上形成有第一弹性支撑结构101a、101b,使得当第一导体30被压入并夹持在一对第一弹性悬臂110、110之间时,第一弹性悬臂110的自由端110a可通过第一弹性支撑结构101a、101b被弹性地支撑在第一容纳室101的内壁上。
如图2和图3所示,在图示的实施例中,第一弹性支撑结构101a、101b包括形成在第一容纳室101的内壁上的第一凸起部101a和形成在主体部100上的第一通孔101b。第一通孔101b位于凸起部101a的附近,使得第一凸起部101a在受压时可弹性变形。
如图3所示,在图示的实施例中,当第一导体30被压入和夹持在一对第一弹性悬臂110、110之间时,第一弹性悬臂110的自由端110a被弹性地支撑在第一凸起部101a上。这样,第一弹性悬臂110就从悬臂梁结构转变为简支梁结构,从而能够有效地降低第一弹性悬臂发生塑性变形的风险。
如图2和图3所示,在图示的实施例中,导电端子10还包括一对第二弹性悬臂120、120。一对第二弹性悬臂120、120用于夹持第二导体(未图示)。一对第二弹性悬臂120、120连接至主体部100并容纳在主体部100的一个第二容纳室102中。
如图2和图3所示,在图示的实施例中,第二导体的直径小于第一导体30的直径,当第二导体被夹持在一对第二弹性悬臂120、120之间时,第二弹性悬臂120、120的自由端与第二容纳室102的内壁不接触。因此,在图示的实施例中,在导电端子10上没有设计用于弹性支撑第二弹性悬臂120的自由端的第二弹性支撑结构。但是,请注意,本发明不局限于此,也可以在导电端子10上设计有用于弹性支撑第二弹性悬臂120的自由端的第二弹性支撑结构,并且该第二弹性支撑结构可与前述第一弹性支撑结构相同。
如图2和图3所示,在图示的实施例中,导电端子10为通过冲切单片金属料板制成的单个金属端子或通过模制工艺制成的单个金属端子。
如图2和图3所示,在图示的实施例中,一对第一弹性悬臂110、110和一对第二弹性悬臂120、120完全相同,并且对称地布置在导电端子10上。
第二实施例

如图5和图6所示,在图示的实施例中,导电端子20包括主体部200和一对第一弹性悬臂210、210。一对第一弹性悬臂210、210用于夹持第一导体30。一对第一弹性悬臂210、210连接至主体部200并容纳在主体部200的一个第一容纳室201中。
如图5和图6所示,在图示的实施例中,在第一弹性悬臂210或主体部200上形成有第一弹性支撑结构,使得当第一导体30被压入并夹持在一对第一弹性悬臂210、210之间时,第一弹性悬臂210的自由端可通过第一弹性支撑结构被弹性地支撑在第一容纳室201的内壁上。
如图5和图6所示,在图示的实施例中,第一弹性支撑结构包括形成在第一弹性悬臂210的自由端处的第一弯钩部210a。当第一导体30被压入和夹持在一对第一弹性悬臂210、210之间时,第一弹性悬臂210的自由端通过第一弯钩部210a被弹性地支撑在第一容纳室201的内壁上。这样,第一弹性悬臂210就从悬臂梁结构转变为简支梁结构,从而能够有效地降低第一弹性悬臂发生塑性变形的风险。
如图5和图6所示,在图示的实施例中,在第一容纳室201的内壁上形成有第一弧形凸起201a。第一弧形凸起201a与一对第一弹性悬臂210、210的自由端的端面相对。这样,如图6所示,当第一导体30被压入和夹持在一对第一弹性悬臂210、210之间时,第一导体30抵靠在第一弧形凸起201a上,从而能够保护第一导体30,以防第一导体30被第一容纳室201的锋利的内壁边缘刮擦和磨损。
如图5和图6所示,在图示的实施例中,导电端子20还包括一对第二弹性悬臂220、220。一对第二弹性悬臂220、220用于夹持第二导体(未图示)。
如图5和图6所示,在图示的实施例中,一对第二弹性悬臂220、220连接至主体部200并容纳在主体部200的一个第二容纳室202中。
如图5和图6所示,在图示的实施例中,在第二弹性悬臂220或主体部200上形成有第二弹性支撑结构,使得当第二导体被夹持在一对第二弹性悬臂220、220之间时,第二弹性悬臂220的自由端可通过第二弹性支撑结构被弹性地支撑在第二容纳室202的内壁上。
如图5和图6所示,在图示的实施例中,第二弹性支撑结构包括形成在第二弹性悬臂220的自由端处的第二弯钩部220a。当第二导体被夹持在一对第二弹性悬臂220、220之间时,第二弹性悬臂220的自由端可通过第二弯钩部220a被弹性地支撑在第二容纳室202的内壁上。这样,第二弹性悬臂220就从悬臂梁结构转变为简支梁结构,从而能够有效地降低第二弹性悬臂发生塑性变形的风险。
如图5和图6所示,在图示的实施例中,在第二容纳室202的内壁上形成有第二弧形凸起202a。第二弧形凸起202a与一对第二弹性悬臂220、220的自由端的端面相对。这样,当第二导体被压入和夹持在一对第二弹性悬臂220、220之间时,第二导体抵靠在第二弧形凸起202a上,从而能够保护第二导体,以防第二导体被第二容纳室202的锋利的内壁边缘刮擦和磨损。
如图5和图6所示,在图示的实施例中,导电端子20为通过冲切单片金属料板制成的单个金属端子或通过模制工艺制成的单个金属端子。
如图5和图6所示,在图示的实施例中,一对第一弹性悬臂210、210和一对第二弹性悬臂220、220完全相同,并且对称地布置在导电端子20上。
本领域的技术人员可以理解,上面所描述的实施例都是示例性的,并且本领域的技术人员可以对其进行改进,各种实施例中所描述的结构在不发生结构或者原理方面的冲突的情况下可以进行自由组合。
虽然结合附图对本发明进行了说明,但是附图中公开的实施例旨在对本发明优选实施方式进行示例性说明,而不能理解为对本发明的一种限制。
虽然本总体发明构思的一些实施例已被显示和说明,本领域普通技术人员将理解,在不背离本总体发明构思的原则和精神的情况下,可对这些实施例做出改变,本发明的范围以权利要求和它们的等同物限定。
应注意,措词“包括”不排除其它元件或步骤,措词“一”或“一个”不排除多个。另外,权利要求的任何元件标号不应理解为限制本发明的范围。
