如图1所示，线缆锁紧装置，包括线缆10以及贯穿所述线缆10并依次设置的锁紧壳体20、密封圈40和对配壳体50；
所述密封圈40收容于所述对配壳体50中，并与对配壳体50的内壁贴合设置，所述锁紧壳体20与所述对配壳体50设置对应的第一卡接结构，所述锁紧壳体20通过所述第一卡接结构可拆卸的固定在所述对配壳体50上，并锁紧所述密封圈40；
所述锁紧壳体20包括锁紧环30，所述锁紧环30收容于所述锁紧壳体20内，所述锁紧壳体20与所述锁紧环30设置对应的第二卡接结构，所述锁紧环30通过所述第二卡接结构可拆卸的固定在所述锁紧壳体20上，当所述锁紧壳体20卡接在所述对配壳体50上时，所述锁紧环30锁紧所述线缆10。
线缆锁紧装置是用来锁紧和固定线缆10的装置，能够使电缆线路通畅。锁紧壳体20将密封圈40锁紧在对配壳体50上，能够保证线缆10与充电装置之间的密封性，防止潮气进入到充电装置内部。锁紧壳体20还包括锁紧环30，锁紧环30的设置能够将线缆10进行固定锁紧，不仅能够防止线缆10在外力的作用下产生位移，保证密封圈40的密封性，同时还能够保证线缆10与电连接装置连接的稳定性，此结构安装拆卸方便，结构简单，固定性和密封性好。
沿所述对配壳体50到所述锁紧壳体20的方向上，锁紧环30收容到所述锁紧壳体20后，锁紧环内壁直径的逐渐减小，达到收紧的状态，能够更好的固定线缆10。
如图2所示，在一具体的实施方式中，沿所述对配壳体50到所述锁紧壳体20的延伸方向上，所述第二卡接结构包括分别设置在所述锁紧环30外侧壁的导向柱31，和设置在所述锁紧壳体20内侧壁的具有容纳所述导向柱31的导向槽21，所述导向柱31在所述导向槽21内滑动。

在一具体的实施方式中，所述导向柱31和所述导向槽21的延伸方向与所述线缆10的轴向方向的夹角为2°-15°。
导向柱31和导向槽21的延伸方向与线缆10的轴向方向设置一定的夹角，说明锁紧环30在工作状态时，内部的直径是不同的，此结构的设置能够保证线缆10沿轴向方向移动，使线缆10固定的更牢固。沿轴向方向，所述导向柱31的延伸方向可以是向线缆10外侧方向延伸，也可以是向线缆10内侧方向延伸。根据实际使用环境和线缆10直径的大小，夹角的具体角度可以具体的设置为2°、4°、6°、8°、10°、12°、15°，夹角越大线缆10固定的越牢固，但是夹角如果超过15°，线缆10的绝缘容易破裂，导 致线缆10漏电；夹角设置小于2°线缆10固定不牢固，所以申请人将夹角的范围设置在2°-15°。
在一具体的实施方式中，沿所述对配壳体50到所述锁紧壳体20的延伸方向上，所述导向槽21与线缆10之间的径向尺寸逐渐减小。
此结构的设置能够防止线缆10向锁紧壳体20的方向移动，起到对线缆10的固定作用。
在一具体的实施方式中，所述锁紧环30与所述线缆10锁紧后，所述锁紧环30的径向内径尺寸为所述线缆10外径尺寸的0.8倍-0.95倍。
具体的，申请人选用10组相同尺寸的线缆10，10组不同尺寸的锁紧环30，以所述锁紧环30的径向内尺寸占所述线缆10外径尺寸的倍数作为变量；
线缆10的一端固定，线缆10另一端与锁紧环30和锁紧壳体20锁紧，锁紧环30与所述线缆10锁紧后，使用拉力测力仪测试线缆10与锁紧环30脱离的拉脱力。
具体的申请人设定为拉脱力大于等于100N为合格。
表1，锁紧环30的径向内径尺寸占线缆10外径尺寸的倍数对锁紧环30与线缆10锁紧程度的影响
如表1可以看出，当锁紧环30的径向内径尺寸占线缆10尺寸的倍数大于0.95倍时，锁紧环30和线缆10的拉脱力小于100N，不符合规定值；当锁紧环30的径向内径尺寸占线缆10尺寸的倍数小于0.8倍时，虽然线缆10和锁紧环30之间没有拉脱，但是线缆10的绝缘层11有损坏，所以申请设定人所述锁紧环30的径向内径尺寸为所述线缆10外径尺寸的0.8倍-0.95倍，此范围既能够保证锁紧环30与线缆10锁紧固定又能保证线缆10的完好。
在一具体的实施方式中，如图1所示，所述第一卡接结构包括分别设置在所述锁紧壳体20侧壁上的至少一个卡接凹槽22，和设置在所述对配壳体50的外侧壁上的至少一个卡接凸台52，所述卡接凹槽22与所述卡接凸台52卡接配合。
根据实际使用环境，锁紧壳体20的侧壁设置一个卡接凹槽22，与之对应的对配壳体50外侧壁上设置一个卡接凸台52，所述卡接凹槽22和卡接凸台52卡接配合，卡接凸台52也可以设置在对配壳体50相对的两侧，也可以四周侧面全部设置，卡接凹槽22与卡接凸台52一一对应设置即可。
在一具体的实施方式中，如图3-图4所示，所述锁紧壳体20侧壁设置有限位卡点，所述锁紧环30外侧壁上设置有限位锁片33，所述限位卡点与所述限位锁片33相对应设置，所述限位卡点通过所述限位锁片33限制所述锁紧环30与所述锁紧壳体20脱离。
限位卡点与限位锁片33相配合，能够有效的防止锁紧环30与锁紧壳体20自动脱离，使锁紧环30对线缆10的锁紧更加可靠。
在一具体的实施方式中，如图3-图4所示，沿轴向方向所述限位卡点包括间隔设置的第一限位卡点23和第二限位卡点24，在所述锁紧环30与所述锁紧壳体20进行预安装状态下，所述限位锁片33通过第一限位卡点23与所述第一限位卡点23和第二限位卡点24卡接；在所述锁紧环30与所述锁紧壳体20工作状态下，所述限位锁片33通过所述第二限位卡点24与所述第二限位点卡接。
如图4所示，第一限位卡点23可以是两个，对称设置在锁紧壳体20侧壁的两端，第二限位卡点也可以是两个，对称设置在所述锁紧壳体20侧壁的两端，限位锁片33与第一限位卡点23和第二限位卡点24对应卡接。
在预安装时，所述限位锁片33通过第一限位卡点23与第一限位点和第二限位卡点24卡接，第一限位卡点23限制锁紧环30与锁紧壳体20脱离，第二限位卡点24限制锁紧环30继续插接到锁紧壳体20内，此时锁紧环30和线缆10并没有完全锁死，可以对锁紧壳体20和锁紧环30的位置做相应的调整。
预安装后，进一步的使限位锁片33通过第二限位卡点24，在工作状态时，限位锁片33与第二限位卡点24卡接，此时锁紧环30与线缆10完全锁紧，并限制锁紧环30与锁紧壳体20脱离。最后锁紧壳体20与对配壳体50连接，实现线缆10锁紧装置的锁紧状态。
在一具体的实施方式中，如图2所示，所述锁紧环30包括第一锁紧环30和第二锁紧环30，所述第一锁紧环30和所述第二锁紧环30的两外侧壁分别设置有至少一个导向柱31，所述锁紧壳体20内设置与所述导向柱31数量对应的导向槽21。
锁紧环30分体设置，第一锁紧环30和第二锁紧环30的对接处设有一定的空隙余量，不仅能更容易的与锁紧壳体20配合起到更好的固定电缆的作用，而且拆装比较容易。
在一具体的实施方式中，如图3-图5所示，所述锁紧壳体20的内侧壁还设置有导向凸台25，所述导向凸台25沿所述锁紧壳体20内壁周向间隔设置。
在锁紧环30与锁紧壳体20预安装状态下，锁紧环30通过导向柱31插入到锁紧壳体20中，在进一步的插入过程中，导向凸台25设置有斜面，在锁紧环插入的过程中起到导向的作用，能够使锁紧环30更容易的插合。导向凸台25沿径向方向突起一定的高度，在工作状态下，导向凸台25的斜面与锁紧环30的外侧壁紧密贴合，能够有效地防止锁紧环在锁紧的过程中向外扩张，使锁紧环30对线缆10锁紧的更牢固。
在一具体的实施方式中，如图3-图4所示，所述锁紧环30内侧壁设置有多级凸起结构37，所述多级凸起结构37凸出于所述锁紧环30内侧壁设置，所述多级凸起结构37沿轴向方向间隔设置在所述锁紧环30内壁上。
凸起结构37的设置能够增大与线缆10连接的夹持力，对线缆10的起到很好的固定作用。
在一具体的实施方式中，如图1、图3和图4所示，所述线缆10包括设置在外周的绝缘层11，所述多级凸起结构37上设置有径向凸起的线缆卡点38，所述线缆卡点38相对于所述多级凸起结构37的径向高度，小于等于所述绝缘层厚度的二分之一。
线缆10的绝缘层柔软，在所述锁紧环30与所述线缆10锁紧时，线缆卡点38可以卡接到绝缘层11外壁，但是线缆卡点38凸起的径向高度过高容易导致线缆卡点38将绝缘层11卡破，所以申请人设置多级凸起结构37的径向高度小于等于绝缘层厚度的二分之一，具体的可以设置为四分之一，八分之一，十分之一。
