具体实施方式
现在将参照附图来详细描述本发明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发明的范围。
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，决不作为对本发明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、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法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。
本发明公开了一种连接器柔性连接结构，如图1-图4所示，
包括连接器本体1、柔性导体4和传输导体5，所述连接器本体1内设置有插接端子2，所述插接端子2的端部设置第一连接件3，所述传输导体5端部设置第二连接件6；
所述柔性导体4一端与所述第一连接件3电性连接，另一端与所述第二连接件6电性连接。
现有的连接器结构都是传输导体5直接连接连接器本体1内的端子。整个连接结构使得连接器和端子处于刚性固定中，在充电枪插拔过程中会出现端子偏磨的现象。偏磨现象是指端子与对插端的插接处由于各个方向受力不均匀出现的反复摩擦，导致镀层破损露出端子本体的现象。露出端子本体后电阻增加，电流减弱，发热量增加，长期如此影响高压充电的安全性和充电效率。而本发明的柔性导体4既能够导电，又能够通过自身具有的柔性，使连接器本体1内的插接端子2能够具有一定的活动空间。当充电枪插入连接器本体1时，插接端子2因为柔性导体4的存在而会随着充电枪插入的力的方向产生些许移动，从而避免刚性接触所造成的某个面受力过大导致的摩擦强度增加。另外，柔性导体4的柔软特性导致其不适合用螺接等方便拆卸的连接方式，只能采用焊接等固定的连接方式，这样就不容易将其与传输导体5分开以方便更换。在这种情况下，通过设置第二连接件6连接柔性导体4和传输导体5可以方便拆卸，即在需要更换连接器本体1时只需分开第二连接件6和传输导体5即可。
进一步的，当所述第二连接件6发生振动时，所述柔性导体4产生形变从而对所述第二连接件6的振动进行缓冲。在车辆行驶中，传输导体5会随着车体发生摆动，长时间的摆动会带动第二连接件6发生振动，而第二连接件6振动时，在刚性的连接中会带动插接端子2抖动，长期抖动会损坏插接端子2和连接器本体1的连接结构，因此，设置柔性导体4能够通过自身的形变阻止第二连接件6的振动传递给插接端子2，从而保护插接端子2。
在一些实施方式中，所述柔性导体4从与所述第二连接件6连接的一端开始，沿所述柔性导体4长度方向，至少占所述柔性导体4长度2％的部分发生径向位移。如果柔性导体4发生径向位移的长度太小，则对振动的缓冲不够，无法充分缓冲第二连接件6的振动，为了寻找合适的柔性导体4发生径向位移占柔性导体4长度的比，发明人进行了相关试验，试验的方法为选择相同的第二连接件6和不同的柔性导体4组成样件，柔性导体4具有不同的能够发生径向位移长度。对样件进行一小时的振动测试，如果阻抗增加的比率大于2％为不合格，说明微动腐蚀依然存在，为不合格，结果如表1所示。
表1：柔性导体4发生径向位移的长度占柔性导体长度的比对阻抗的影响
如表1所示，当柔性导体4发生径向位移的长度占柔性导体长度的比小于2％时，振动试验后柔性导体4和第二连接件6之间的阻抗上升大于2％，因此，发明人优选所述柔性导体4从与所述第二连接件6连接的一端开始，沿所述柔性导体4长度方向，至少占所述柔性导体4长度2％的部分发生径向位移。
因此，发明人通过测试发现柔性导体4振动的部分如果小于柔性导体4总长度的2％，则无法对第二连接件6的振动起到有效的缓冲，振动产生的力集中释放在柔性导体4和第二连接件6的连接处，如果长时间这样，很容易导致两者的脱离，造成断路，因此发明人优选至少占所述柔性导体4长度2％的部分发生径向位移。
在一些实施方式中，所述柔性导体4从与所述第一连接件3连接的一端开始，沿所述柔性导体4长度方向，至少占所述柔性导体4长度1％的部分不发生径向位移。
如果柔性导体4不发生径向位移的部分过小，则第二连接件6的振动还是会传递给第一连接件3，为了找合适的柔性导体4不发生径向位移占柔性导体4长度的比，发明人进行了相关试验，试验的方法为选择相同的第一连接件3和不同的柔性导体4组成样件，柔性导体4具有不同的能够发生径向位移长度。对样件进行一小时的振动测试，如果阻抗增加的比率大于2％为不合格，说明微动腐蚀依然存在，为不合格，结果如表2所示。
表2：柔性导体4不发生径向位移的长度占柔性导体长度的比对阻抗的影响
如表2所示，当柔性导体4不发生径向位移的长度占柔性导体长度的比小于1％时，振动试验后柔性导体4和第一连接件3之间的阻抗上升大于2％，为不合格。因此，发明人优选所述柔性导体4从与所述第一连接件3连接的一端开始，沿所述柔性导体4长度方向，至少占所述柔性导体4长度1％的部分不发生径向位移。
