Description

一种连接器
本申请要求申请日为：2015年11月13日，申请号为：201520907924.X，名称为：“一种连接器”的中国专利申请的优先权。
技术领域
本申请涉及通信连接技术领域，更具体地，本申请涉及一种连接器。
背景技术
连接器的端子与外壳需紧密配合，不允许有间隙，否则连接器会晃动，影响连接器的使用，存在安全问题。所以线材本身的选择有了较大的限制，通常设计的线材弹性释放件(Strain Relief)的尺寸需小于连接器的尺寸，线材才能从外壳的线孔穿出，强行组装会造成SR磨损或者破坏线材；如果线材本身或SR的尺寸大于连接器的尺寸，就会出现线材穿不过外壳穿线孔的情况，无法适应大直径数据线的使用。
发明内容
本申请的一个目的是解决现有连接器的外壳装配大直径数据线时易造成数据线划伤甚至损坏的技术问题。
根据本申请的一个方面，提供一种连接器。该连接器包括：
端子，包括插头和与所述插头信号连接的接线端；
数据线；
弹性垫圈；以及
套设于所述接线端的外壳，所述外壳设有第一端敞开的腔体，所述腔体具有设定的高度；所述外壳的与敞开端相对的第二端设有线孔，所述线孔的直径大于所述腔体的高度；沿所述腔体的高度方向具有相对设置的第一边和第二边；所述第一边所在的平面为第一表面；所述第一边设有与所 述线孔的边缘相匹配的凹槽；所述凹槽的远离所述线孔的一端设有由所述凹槽的底边向所述第一表面过度的斜面；所述数据线穿过所述线孔且与所述接线端信号连接；所述数据线与所述线孔之间设有弹性垫圈。
可选地，所述第二边所在的平面为第二表面；所述第二边设有与所述线孔的边缘相匹配的凹槽；所述凹槽的远离所述线孔的一端设由所述凹槽的底边向所述第二表面过度的斜面。
可选地，所述斜面的横截面为楔形。
可选地，所述数据线的直径为3.2mm-3.6mm。
可选地，所述线孔的直径为4.80mm。
可选地，所述外壳的材质为塑料或者塑胶。
可选地，所述弹性垫圈的材质为橡胶、塑料或者塑胶。
可选地，所述外壳一体注塑成型。
本申请的一个技术效果在于，端子的接线端连接大直径数据线，组装壳体时，先将弹性垫圈套设到大直径数据线的设定位置；然后，使用微型治具或者手工挤压外壳，使大直径数据线的自由端穿过线孔；接下来，弹性垫圈到达凹槽区域。由于斜面的存在，使得弹性垫圈的安装省力。弹性垫圈从凹槽继续深入，由于凹槽的存在，使得壳体的第一边与第二边对弹性垫圈的挤压力变小，安装省力。最后，弹性垫圈到达线孔处，安装完毕。该连接器的壳体可以有效避免组装时，弹性垫圈或者数据线的划伤甚至损坏。该连接器适于大流量数据或者大电流电力的传输。
通过以下参照附图对本申请的示例性实施例的详细描述，本申请的其它特征及其优点将会变得清楚。

具体实施方式
现在将参照附图来详细描述本申请的各种示例性实施例。应注意到：除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本申请的范围。
以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本申请及其应用或使用的任何限制。
对于相关领域普通技术人员已知的技术和设备可能不作详细讨论，但在适当情况下，所述技术和设备应当被视为说明书的一部分。
在这里示出和讨论的所有例子中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它例子可以具有不同的值。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
本申请提供了一种连接器，参照图3，该连接器用于数据或者电力的传输，尤其适用于大流量数据或者大电流电力的传输。该连接器包括：端子2、数据线3、弹性垫圈4和外壳1。其中，端子2包括插头201和与插头201信号连接的接线端202，插头201与接线端202分别设于端子2的两端。在本实施例中，插头201是USB插头。通常情况下，插头201的横截面为矩形，接线端202也为矩形。其他实施方式中，插头201也可以为小头USB插头，或者Type-C插头，本领域技术人员可以根据实际需要进行选择，本申请对此不做限定。弹性垫圈4套设于数据线3，且与线孔102接触。弹性垫圈4位于数据线3和线孔102之间，受到数据线3和线孔102的挤压，以对数据线3产生弹性应力。该弹性应力为径向弹性应力，可以增大数据线3与弹性垫圈4之间的摩擦力，防止数据线3滑动。
参照图1-2，外壳1具有腔体，外壳1套设于接线端202以形成对接线端202的保护，接线端202位于腔体内，以防止水或者灰尘进入。腔体 具有设定的高度，通常接线端202的高度为4.5mm。外壳1设有敞开端103，插头201凸出于敞开端103并且裸露。为防止接线端202的晃动，外壳1的腔体设计成与接线端202的轮廓相匹配的结构，使得接线端202在外壳1中更加牢固。外壳1还设有线孔102。数据线3穿过线孔102，与接线端202信号连接。本领域技术人员可以理解，通常情况下，USB连接器的高度通常为4.5mm，与USB连接器连接的数据线3常用的直径为2.3mm、2.5mm或者2.8mm。与USB连接器配合的外壳1，通过大直径数据线时易造成数据线3或者弹性垫圈4划伤。
在本实施例中，参照图2，沿腔体的高度方向具有相对设置的第一边和第二边。第一边所在的平面为第一表面。第一边设有与线孔102的边缘相匹配的凹槽101。凹槽101的远离线孔102的一端设有由凹槽101的底边向第一表面过度的斜面。凹槽101的深度可以根据需要进行设计，本申请对此不加限定。凹槽101的斜面可以是弧形也可以是其他形状。
进一步地，第二边所在的平面为第二表面。第二边设有与线孔102的边缘相匹配的凹槽101。凹槽101的远离线孔102的一端设由凹槽101的底边向第二表面过度的斜面。凹槽101的深度可以根据需要进行设计。第一边的凹槽101与第二边的凹槽101相对设置，使得数据线3在安装时，外壳1的内部有更大的容纳空间，可以更省力地将数据线3组装到位。
为了使数据线3更容易组装，斜面的横截面设计为楔形。弹性垫圈4到达横截面时，容纳空间逐渐增大，使得弹性垫圈4受到第一边和第二边的挤压力逐渐减小，组装更容易。
特别地，数据线3为大直径数据线，该大直径数据线的直径为3.2mm-3.6mm。数据线3的直径可以根据需要进行设计。本领域的技术人员可以理解，当数据线3变粗时，可以选择相对较薄的弹性垫圈4以便于安装。进一步地，线孔102的直径为4.80mm，以便适应大直径数据线的安装。当然，也可以根据需要对线孔102的直径进行设计，本申请对此不做限定。大直径数据线有利于大流量数据传输或者大电流的电力传输。
更进一步地，为了便于制造和使用，并具有良好的韧性，外壳1的材质为塑料或者塑胶。为了使弹性垫圈4容易安装并且获得合适的弹性应力。 弹性垫圈4的材质为橡胶、塑料或者塑胶。为了便于加工，节省加工工艺，外壳1采用一体注塑成型的方式进行加工。
本申请提供的连接器，端子2的接线端202连接大直径数据线，组装壳体时，先将弹性垫圈4套设到大直径数据线的设定位置；然后，使用微型治具或者手工挤压外壳1，使大直径数据线的自由端穿过线孔102；接下来；弹性垫圈4到达凹槽101的区域。由于斜面的存在，使得弹性垫圈4的安装省力。弹性垫圈4从凹槽101继续深入，由于凹槽101的存在，使得壳体的第一边与第二边对弹性垫圈4的挤压力变小，安装省力。最后，弹性垫圈4到达线孔102处，安装完毕。安装十分方便。凹槽101的斜面形成的过度区域，可以有效防止弹性垫圈4或者数据线3被划伤甚至损坏。由于弹性垫圈4可以具有更大的外径，所以，可以使用更大直径的数据线3，该连接器适应大流量数据或者大电流电力的传输。
虽然已经通过示例对本申请的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上示例仅是为了进行说明，而不是为了限制本申请的范围。本领域的技术人员应该理解，可在不脱离本申请的范围和精神的情况下，对以上实施例进行修改。本申请的范围由所附权利要求来限定。
