Description

一种连接器组件及其连接器
技术领域
本发明涉及一种连接器组件及其连接器。
背景技术
连接器是两个设备或者部件之间常用的连接装置，在实际生产和生活中，例如机箱模块与机柜之间，电池箱与电池舱或充电架之间以及两块PCB板之间均会遇到需要用到连接器组件连接的情况，其中两块PCB板之间传输信号所用到的连接器组件主要为差分对连接器组件，对信号的传输速度以及传输质量、密度等均有着十分严格的要求。
现有的用于两个PCB板之间的连接器组件均为两件式对插结构，插头和插座对插在一起，要求侧向偏移最大为0.15mm。若偏移超差，则会导致插头、插座的信号导体和接地导体距离过小而出现耐压能力不足等问题。因此目前的用于PCB板之间连接的电连接器对两PCB板之间的对正精度有着十分严格的要求，但是在实际的应用过程中，两个PCB板之间的对正是比较困难的。
发明内容
本发明的目的在于提供一种连接器组件，以降低对需要连接的两部件的对正要求；本发明的目的还在于提供一种该连接器组件的连接器。
为实现上述目的，本发明连接器的技术方案是：
连接器，包括壳体，壳体上沿插接方向的前端为浮动插接端，后端为尾端，壳体的尾端固定有多个固定接触单元，多个固定接触单元沿垂直于插接方向排布，壳体内在靠近浮动插接端的一侧间隙浮动装配有与各个固定接触单元对应的偏斜补偿接触单元，偏斜补偿接触单元沿垂直于插接方向可相对于固定接触单元偏斜浮动，偏斜补偿接触单元的前端形成用于与适配连接器的适配接触单元连接的接触端，后端与固定接触单元的前端导电接触。
更进一步的，为了方便偏斜补偿接触单元和固定接触单元的组装，所述壳体为分体式结构，壳体包括用于安装固定接触单元的固定壳体部分，还包括与固定壳体部分固定连接的用于安装偏斜补偿接触单元的补偿壳体部分。安装更加方便。
更进一步的，为了安装方便，所述补偿壳体部分为分体式对扣结构，补偿壳体部分的相对两端设有用于挡止对应的偏斜补偿接触单元的挡止结构。方便偏斜补偿接触单元的装配，同时防止偏斜补偿接触单元从补偿壳体部分内脱出，结构比较简单。
更进一步的，为了方便偏斜补偿接触单元与固定接触单元之间的适配插接，所述固定壳体部分具有用于容纳固定接触单元的固定容纳孔，固定容纳孔的靠近偏斜补偿接触单元的一端边沿处设有与固定接触单元轴向挡止并径向向内延伸的突起，所述突起具有用于引导偏斜补偿接触单元的对应端部导向插入的引导楔形面。具有一定的导引作用，结构比较简单，而且对固定接触单元起到一定的保护作用。

具体实施方式
下面结合附图对本发明的实施方式作进一步说明。
本发明的连接器组件的具体实施例1，如图1至图5所示，该连接器组件包括两部分，即相互适配插接的第一连接器2和第二连接器3，同时，在本实施例中，该连接器组件为差分连接器组件，连接器组件的结构如图1所示，定义第一连接器2和第二连接器3的插接方向为上下方向，在本实施例中，第一连接器2和第二连接器3均包括壳体和设置在壳体内的接触单元，且壳体均为矩形的绝缘壳体，当然，在其他实施例中，壳体的形状还可以根据实际的需要任意设计为其他形状，其材质可还可以为金属，在壳体内另外设置绝缘体安装即可。
对于第一连接器2来说，其壳体包括两部分，分别为用于固定在对应的设备1上的固定壳体部分21，以及固定连接在固定壳体部分21上的补偿壳体部分22，对应的在固定壳体部分21内固定有固定接触单元211，在补偿壳体部分22内活动装配有偏斜补偿接触单元221，偏斜补偿接触单元221与固定接触单元211相互适配插接从而能够将设备1上的信号通过固定接触单元211连通到偏斜补偿接触单元221上。当然，在本实施例中，对于固定壳体部分21和补偿壳体部分22来说，二者之间相对固定，其具体的固定形式本领域技术人员可以根据实际的操作选择，不再详细叙述，如可以通过螺钉锁紧连接，卡扣卡紧实现相对固定，或者是直接通过粘接连接在一起；同时，在本实施例中，固定壳体部分21与补偿壳体部分22之间为可拆连接，当然，在其他实施例中，固定壳体部分21与补偿壳体部分22之间也可以为不可拆连接；二者也可以为一体式结构。
以第一连接器2的前端为浮动插接端，对于固定壳体部分21来说，其为绝缘结构，其内部沿插接方向延伸设置有固定容纳孔，上述的固定接触单元211装配在固定容纳孔中，同时在固定容纳孔的前端的孔口边沿沿径向向内延伸设有突起4，这样能够对固定接触单元211起到一定的保护作用，防止误插以及防止固定接触单元211从固定壳体部分21内向前脱出于固定壳体部分21内。
对于补偿壳体部分22来说，其也为绝缘结构，其内部沿插接方向延伸设有活动容纳孔，上述的偏斜补偿接触单元221活动装配在活动容纳孔中，具体的为活动容纳孔的孔径要大于偏斜补偿接触单元221的外径，从而能够实现偏斜补偿接触单元221沿径向间隙浮动，以满足第一连接器2和第二连接器3连接时的侧向偏差对正。
对于固定接触单元211来说，其包括相互注塑胶封装在一起的固定接触件和固定绝缘体，同时在固定绝缘体的外侧设置有固定屏蔽层，通过固定屏蔽层与固定壳体部分21之间的相对固定结构实现固定壳体部分21与固定接触单元211之间的相对固定；同时，由于该连接器组件为差分连接器组件，上述的固定接触件有相对布置的两个，固定接触件的后端具有用于与对应的设备1连接的固定鱼眼。当然，在其他实施中，固定接触件的后端也可以是与外接设备的连接器适配插接的插接接触端，也可以直接连接导线等结构。固定接触件的前端为喇叭口形的扩口结构，用于引导偏斜补偿接触单元221的补偿接触件的导正插入。偏斜补偿接触单元的与固定接触单元插接的对应端部受固定接触件的弹性挤压保持导电接触，也可以通过将固定接触件的扩口结构设置为弧形面，偏斜补偿接触单元的对应端部在浮动过程中受到固定接触件的强压而时刻具有一定的侧面与弧形面导电接触，这样也能够保证固定接触单元与偏斜补偿接触单元的导电连接。
对于偏斜补偿接触单元221来说，其包括相互注塑封装在一起的活动接触件和活动绝缘体，活动绝缘体的外侧设有活动屏蔽层，活动屏蔽层的外径尺寸小于活动容纳孔的尺寸，这样能够保证偏斜补偿接触单元221在活动容纳孔内的径向浮动。当然，为了实现偏斜补偿接触单元221与补偿壳体部分22之间的装配，在本实施例中，补偿壳体部分22为分体式对扣结构，同时在补偿壳体部分22的相背两端设有用于挡止偏斜补偿接触单元221从补偿壳体部分中脱出的限位结构，具体的为偏斜补偿接触单元221的两端均具有台阶面，同时在补偿壳体部分22的对应位置设有供偏斜补偿接触单元221伸出并与台阶面挡止的限位孔，限位孔内壁上具有挡沿，挡沿与台阶面挡止限位配合保证偏斜补偿接触单元221不会从补偿壳体部分22中脱出。装配时将偏斜补偿接触单元221插入至活动容纳孔中，将补偿壳体部分22与固定壳体部分21相对装配，最后与对应的固定接触单元211适配插接，实现第一连接器2的组装。上述的偏斜补偿接触单元221具有与第一连接器2的固定接触单元211适配插接的第一接触端，还具有与第二连接器3的适配接触单元32适配插接的第二接触端。
对于第二连接器3来说，在本实施例中，其具体结构与第一连接器2中的固定壳体部分21和固定接触单元211的组合形式一致，不再详细叙述，通过在第一连接器2的固定壳体部分21的前端设置补偿壳体部分22，这样能够增大固定接触单元211与适配接触单元32之间的插接距离。而具体的大偏移插合原理由图3可知，两个连接器的水平方向的偏移量为△2，则在连接器插合处偏移量为△1，补偿壳体部分22内的偏斜补偿接触单元221的长度为H，在标称堆叠高度情况下偏斜补偿接触单元221的第二接触端至第二连接器3内的距离为h，根据相似三角形原理，则：△1/△2 = h/H。从而通过结构上的巧妙设计减小了产品对插时的实际偏移量。
这样设置的连接器组件，在实际的插接过程中，可通过补偿壳体部分22以及偏斜补偿接触单元221的作用来使第一固定接触单元211和适配接触单元32之间的相对距离增加，并通过偏斜补偿接触单元221与固定接触单元211和适配接触单元32之间的配合来减小插合部位的偏移量，从而能够保证在第一连接器2的固定壳体部分21与第二连接器3之间的侧向偏移较大时，补偿壳体部分22和偏斜补偿接触单元221的设置使得第一连接器2和第二连接器3的插接仍具有较小的相对偏差以及较高的对正精度，结构比较简单，而且为连接器组件的小型化设计、高速数据传输设计等提供了可能。
上述的实施例1是对本发明的连接器组件的最优实施方式，在其他实施例中，可以根据实际的需要对相应的结构进行调整和简化：
本发明的连接器组件的实施例2，在本实施例中，对连接器组件的结构做了简化，具体的为连接器组件包括适配插接的第一连接器和第二连接器，第二连接器具有适配接触单元，第一连接器包括壳体，壳体上沿插接方向的前端为浮动插接端，后端为尾端，壳体的尾端固定有多个固定接触单元，多个固定接触单元沿垂直于插接方向排布，壳体内在靠近浮动插接端的一侧间隙浮动装配有与各个固定接触单元对应的偏斜补偿接触单元，偏斜补偿接触单元沿垂直于插接方向可相对于固定接触单元偏斜浮动，偏斜补偿接触单元的前端形成与适配接触单元连接的接触端，后端与固定接触单元的前端导电接触。
在连接器相互连接时，通过偏斜补偿接触单元的作用来使第一固定接触单元和适配接触单元之间的相对距离增加，并通过偏斜补偿接触单元与第一固定接触单元和适配接触单元之间的配合来减小插合部位的偏移量，从而能够保证在第一连接器的固定壳体与第二连接器之间的侧向偏移较大时，偏斜补偿接触单元在壳体内可偏斜摆动的浮动设置使得第一连接器和第二连接器的插接仍具有较小的相对偏差以及较高的对正精度，结构比较简单，而且为连接器组件的小型化设计、高速数据传输设计等提供了可能。
本发明的连接器组件的实施例3，作为对实施例2的进一步优化，壳体为分体式结构，壳体包括用于安装固定接触单元的固定壳体部分，还包括与固定壳体部分固定连接的用于安装偏斜补偿接触单元的补偿壳体部分。方便偏斜补偿接触单元和固定接触单元的组装，安装更加方便。当然，在其他实施例中，壳体可以为整体式结构。
本发明的连接器组件的实施例4，作为对实施例3的进一步优化，补偿壳体部分为分体式对扣结构，补偿壳体部分的相对两端设有用于挡止对应的偏斜补偿接触单元的挡止结构。方便偏斜补偿接触单元的装配，同时防止偏斜补偿接触单元从补偿壳体部分内脱出，结构比较简单，安装方便。当然，在其他实施例中，可以在偏斜补偿接触单元与补偿壳体之间设置限位件的形式实现挡止限位。
本发明的连接器组件的实施例5，作为对实施例3的进一步优化，固定壳体部分具有用于容纳固定接触单元的固定容纳孔，固定容纳孔的靠近偏斜补偿接触单元的一端边沿处设有与固定接触单元轴向挡止并沿径向向内延伸的突起，所述突起具有用于引导偏斜补偿接触单元的对应端部导向插入的引导楔形面。方便偏斜补偿接触单元与固定接触单元之间的适配插接，具有一定的导引作用，结构比较简单，而且对固定接触单元起到一定的保护作用。
本发明所涉及的连接器的实施例，其结构与上述的连接器组件的实施例1~5任意一个中的第一连接器的结构一致，不再详细展开。
