本专利申请涉及电气连接领域，尤其涉及用于在对配的公端子和母端子之间建立电连接和机械连接的弹性接触件。
背景技术
在电气连接领域，电连接器广泛应用于各种电气线路中，起着传输电流的作用。电连接器通常包括彼此配合的插座和插头。电连接器的插座和插头内各自装有端子，通常要求这些端子之间具有较佳的配合，以满足大电流传输要求。若端子之间配合过松，则容易出现接触不良，从而降低电流传输效率，甚至中断电流传输；但若配合过紧，则不利于电连接器的插拔。
冠簧是一种用于在对配的端子之间建立电连接和机械连接的弹性接触件。典型的冠簧被装于母端子内，并与插入母端子的公端子发生电接触和机械接触。例如，中国实用新型专利授权公告号为CN203423290U描述了一种用于桥接接触套筒(即母端子)与接触销钉(即公端子)之间的电气触点的接触弹簧。然而，在诸如高压大电流连接的开发和应用场合中，这种冠簧仍存在进一步的改进空间。

具体实施方式
下面结合具体实施例和附图对本专利申请作进一步的说明，在以下的描述中阐述了更多的细节以便于充分理解本专利申请，但是本专利申请显然能够以多种不同于此描述的其它方式来实施，本领域技术人员可以在不违背本专利申请内涵的情况下根据实际应用情况作类似推广、演绎，因此不应以此具体实施例的内容限制本专利申请的保护范围。
本申请使用了特定词语来描述本申请的实施例。如“一个实施例”、“其他实施例”、和/或“一些实施例”意指与本申请至少一个实施例相关的某一特征、结构或特点。因此，应强调并注意的是，本说明书中在不同位置两次或多次提及的“一个实施例”或“其他实施例”或“一些实施例”并不一定是指同一实施例。此外，本申请的一个或多个实施例中的某些特征、结构或特点可以进行适当的组合。
应当注意的是，为了筒化本申请披露的表述，从而帮助对一个或多个实施例的理解，后文对本申请实施例的描述中，有时会将多种特征归并至一个实施例、附图或对其的描述中。但是，这种披露方法并不意味着本申请对象所需要的特征比权利要求中提及的特征多。实际上，实施例的特征要少于在下文披露的单个实施例的全部特征。
参照图1-4，图1示出了根据本专利申请的一个实施例的冠簧10的立体图。图2示出了根据本专利申请的一个实施例的冠簧10在卷绕前的内侧平面示意图。图3示出了根据本专利申请的一个实施例的冠簧10在卷绕前的侧视图。图4示出了根据本专利申请的一个实施例的冠簧的根据图1中的视角A的侧视图。参见图1，冠簧10可呈大致筒状结构，包括分别位于两端的第一环状部分11A和第二环状部分11B，以及连接于第一环状部分11A与第二环状部分11B之间的多个弹性梁12。基于冠簧10的这种筒状结构，可定义内侧I和外侧E。沿着圆筒的环方向，冠簧10可具有第一端13A和第二端13B，其中第一端13A与第二端13B之间可具有第一间隙15。第一间隙15的大小可根据需要而进行调整。参见图2，冠簧10可以是由单片导电材料形成的，并且可通过将所述单片导电材料的第一端13A和第二端13B朝向内侧I卷绕形成如图1所示的具有筒状结构的冠簧10。
如图1-2所示，冠簧10可包括多个弹性梁12，这些弹性梁12可彼此平行设置并且两端对齐，并且相邻的弹性梁12之间可具有第二间隙14。每一个弹性梁12可包括形成外弹臂121的部分和形成内弹臂123的部分。沿着冠簧10的圆筒结构的径向方向，外弹臂121向外侧凸起以定义外触点，内弹臂123向内侧凸起以定义内触点。
位置相邻的弹性梁12可反向设置，从而每一个弹性梁12的外弹臂121可与相邻弹性梁12的对应内弹臂123相邻，换言之，每一个弹性梁的外触点与相邻弹性梁的内触点沿着所述筒状元件的圆周方向交错排列。
参见图3，以弹性梁12两端点的连线为弹性梁的纵轴线L，则内弹臂123所定义的内触点(例如为公针触点)到弹性梁轴线L的距离大于外弹臂123所定义的外触点(例如为母针触点)到弹性梁轴线L的距离。在另一些实施例中，内弹臂123所定义的内触点(例如为公针触点)到弹性梁轴线L的距离可以小于外弹臂123所定义的外触点(例如为母针触点)到弹性梁轴线L的距离。
外弹臂121的臂长度可以被确定为等于向外凸起的外弹臂121的弧长。类似地，内弹臂123的臂长度可以被确定为等于向内凸起的内弹臂123的弧长。在一些实施例中，如图1-2所示的，向外凸起的外弹臂121与向内凸起的内弹臂123可相接于接合125处。接合125优选地偏离弹性梁的中心，即外弹臂121的臂长度不同于内弹臂123的臂长度。例如，同一弹性梁12上的外弹臂121的臂长度可以小于或大于同一弹性梁12上的内弹臂123的臂长度。参见图4，同一弹性梁12上的外弹臂121朝向外侧的凸起程度与内弹臂123朝向内侧的凸起程度可以是不同的，从而使得在图4的视角中，内弹臂123所定义的内触点比外弹臂所定义的外触点更为凸出。换言之，沿圆筒的径向方向，外弹臂121向外凸起的距离小于内弹臂123向内凸起的距离。在其他实施例中，沿圆筒的径向方向，外弹臂121向外凸起的距离可以大于内弹臂123向内凸起的距离。
在图5-6所示的应用中，相比于母端子20，冠簧10和公端子30之间更加需要基于弹簧形变而产生的作用力以确保可靠接触。因此，通过差异化设计同一弹性梁12上的外弹臂121和内弹臂123，可以使弹簧形变产生的作用力更加集中发生于冠簧10的内侧(图3的I侧，与公端子接触一侧)。因此，冠簧10在具有较小尺寸(例如，较短的弹性梁12)的情况下获得更好的弹性，从而提高电连接器1(如以下的图5-6中所示的)的电流传输效率。
如图3所示，由于相邻位置的弹性梁12是镜像设置的，因此，冠簧10在装 配中没有正向反向之分，因此，免除了防错设计，并保证了插拔力的一致性。
虽然在以上描述的实施例中，每一个弹性梁12仅包括一个外弹臂121和一个内弹臂123，但在其他实施例中，每一个弹性梁12可以包括一个或多个外弹臂121以及一个或多个内弹臂123。
参照图5-6，图5示出了根据本专利申请的一个实施例的电连接器1中的冠簧10、母端子20和公端子30三者在安装前的示意图。图6示出了根据本专利申请的一个实施例的电连接器1中的公端子30与安装有冠簧10的母端子20在安装前的示意图。
如图5所示，公端子30可具有安装腔21，安装腔21可用于容纳冠簧10和公端子30。冠簧10以及公端子30的形状和尺寸可与母端子20的安装腔21的形状和尺寸相匹配，以便适配安装。如图6所示的，当冠簧10被安装到母端子20的安装腔21内时，安装腔21的内壁可以与冠簧10的外弹臂121的至少一部分(例如，外触点)接触。当将公端子30插入安装有冠簧10的母端子20的安装腔21内时，公端子30的外壁31可以与冠簧10的内弹臂123的至少一部分(例如，内触点)接触。当电连接器1的冠簧10、母端子20和公端子30三者安装在一起时，母端子20的内壁与冠簧10的外弹臂121之间可具有相互作用力，公端子30的外壁31与冠簧10的内弹臂123之间可具有相互作用力，这可以提高母端子20与公端子30之间的连接可靠性并进一步提高电连接器1的电流传输效率。
在其他变化例中，根据实际应用需要，可以使外弹臂所定义的外触点比内弹臂所定义的内触点更为凸出，从而使弹性更为集中于冠簧和母端子之间。
上述实施例中，以“冠簧”来称呼附图标记为10的弹性接触件。应该理解，更为广义的弹性接触件应涵盖一种筒状元件，所述筒状元件包括位于两端的环状部分，以及连接于两端环状部分之间的多个弹性梁。
尽管己经根据本公开的优选实施例描述了本专利申请，然而并不旨在受限于此，而是仅受所附权利要求书中所阐述的范围限制。本领域技术人员应该理解，可对本文中所描述的实施例作出各种修改和改变，而不背离如所附权利要求中所阐述的本专利申请的更宽泛精神和范围。

  7. 如权利要求1-6中任一项所述的弹性接触件，其特征在于，所述多个弹性梁彼此平行并且两端对齐，从而每一个弹性梁的外触点与相邻弹性梁的内触点沿着 所述筒状元件的圆周方向交错排列。
  8. 如权利要求1-6中任一项所述的弹性接触件，其特征在于，所述弹性接触件由单片导电材料形成。
  9. 如权利要求8所述的弹性接触件，其特征在于，所述弹性接触件是通过将所述单片导电材料卷绕而形成的。
  10. 如权利要求9所述的弹性接触件，其特征在于，卷绕而成的所述弹性接触件的所述两端之间具有间隙。
  11. 如权利要求1所述的弹性接触件，其特征在于，所述弹性接触件是冠簧。
  12. 如权利要求1所述的弹性接触件，其特征在于，每一个弹性梁包括一个或多个所述外弹臂，以及一个或多个所述内弹臂。
  13. 一种电连接器，其特征在于，所述电连接器包括：
    如权利要求1-12中任一项所述的弹性接触件；
    母端子，所述母端子具有安装腔，所述安装腔用于容纳所述弹性接触件，所述安装腔的内壁用于与所述弹性接触件的外弹臂的至少一部分接触；以及
    公端子，所述公端子用于插入所述母端子的所述安装腔内并与所述弹性接触件的内弹臂的至少一部分接触。
