Description
技术领域
本发明属于电动汽车充电线缆技术领域，尤其涉及一种液冷充电线束用液电分离连接器。
背景技术
随着汽车工业的发展以及全球环保意识的提高，使得市场对新能源汽车的需求越来越大，而与新能源汽车相关的充电配套设备的重要性也逐渐凸显出来。目前市面上的大功率充电枪、座的冷却系统多采用油冷介质冷却方式，使充电导体完全浸没在冷却介质中，通过冷却介质在整个冷却系统中的循环带走线缆热量。然而市面上此种冷却方式的接线尾部液电分离方式多较为复杂，且普遍采用的用螺钉将两者锁紧的连接方式，既不方便操作、增加装配成本，亦不安全，原因如下：（1）因为连接点在铜排内部，所以不好操作；且锁螺钉时，一旦螺钉脱落掉进铜排腔体，不容易取出（2）产品在实际周转、装配及使用过程中，难免会受到振动，振动极易使螺钉晃动、松脱，螺钉一旦晃动则连接部位热量会极高，很可能会导致液冷系统失效；若是螺钉松脱，则整套充电线束很可能会直接报废。例如直接使导体与铜排之间采用螺钉连接方式，连接既不可靠，也不方便将导体上的螺钉部插入铜排内的螺孔，且极易使导体扭曲；又例如采用外设的螺钉将导体压紧在铜排内，此种方式无法识别导体是否插入到位、是否存在冗余导体扭曲在管道中。
发明内容
为解决现有技术不足，本发明提供一种液冷充电线束用液电分离连接器，导体与铜排之间具有良好的连接稳定性，同时可避免导体发生扭曲。
为了实现本发明的目的，拟采用以下方案：
一种液冷充电线束用液电分离连接器，包括：铜排，其内部穿设有导体。铜排沿导体穿设方向的两端分别设有压接管及进液管，且铜排内部具有与压接管及进液管同轴连通的进液孔，导体穿过进液管，且导体末端穿设于压接管内，压接管与导体之间通过压合相连，铜排的侧壁开设有与进液孔连通的出液孔，出液孔的外部与一出液管连通，出液管及进液管分别与冷却系统的入口和出口相连，铜排具有连接孔。
本发明的有益效果在于：
1、导体与铜排的连接方式，采用传统成熟的压接方式，且易于操作，装配工艺简单，且具有较好的密封性能，能有效避免导体脱落，以及防止导体扭曲。
2、具有较强的兼容性，宝塔接头、卡箍、进液管及出液管均可根据实际需求进行选择，并且此类零件多为标准件，无需进行非标定制，可有效降低成本。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面结合附图对本发明的实施方式进行详细说明，但本发明所描述的实施例是本发明一部分实施例，而不是全部的实施例。
如图1、图2及图4、图5所示，一种液冷充电线束用液电分离连接器，包括：铜排1，其内部穿设有导体6。铜排1沿导体6穿设方向的两端分别设有压接管11及进液管4，且铜排1内部具有与压接管11及进液管4同轴连通的进液孔14，导体6穿过进液管4，且导体6末端穿设于压接管11内，压接管11与导体6之间通过压合相连。具体的操作方式是，利用压接工具或者设备对压接管11进行压接，使其中段向轴线方向产生缩颈，从而使缩颈部位的内壁与导体6的外壁紧密贴合，此方式不仅可对导体6进行固定，同时还起到了密封的作用，防止冷却液体渗出。铜排1的侧壁开设有与进液孔14连通的出液孔13，出液孔13的外部与一出液管10连通，出液管10及进液管4分别与冷却系统的入口和出口相连，更具体的，冷却系统包括水泵、散热装置、控制阀门及连接管道等，铜排1具有连接孔12，用于连接外部电源以及实现连接器的装配功能。冷却液从进液管4进入进液孔14内，使导体6浸在冷却液中，利用冷却液吸收导体6的热量，冷却液从出液孔13经出液管10排出，从而实现对连接器散热的目的，排出的冷却液经过冷却系统的冷却后便可从进液管4再次进入铜排1内，从而实现循环散热的目的，冷却液在连接器内的流动轨迹如图5中的箭头标识所示。
铜排1及压接管11可根据实际的应用场景制作成不同的尺寸，因为采用压接的方式对导体6进行固定，因此仅需要根据压接管11的具体尺寸适应性的调整压接力即可。
优选的，如图2及图5所示，进液管4及出液管10与铜排1之间均通过宝塔接头3相连，更具体的，宝塔接头3的一端通过螺纹结构与铜排1相连，螺纹结构为管螺纹结构，以提高密封性，宝塔接头3的另一端分别插设于进液管4及出液管10内，并采用卡箍5将进液管4及出液管10锁紧在对应的宝塔接头3上。
进一步优选的，如图2、图3所示，宝塔接头3的外壁设有螺母结构，螺母结构朝向铜排1一侧的端面具有环形槽31，环形槽31内设有密封圈2，密封圈2的侧面与铜排1的外壁贴合，以保证宝塔接头3与出液孔13及进液孔14之间的密封性，同时螺母结构可方便宝塔接头3的拆装。
优选的，如图2所示，宝塔接头3与进液管4及出液管10连接段部位外壁具有倒刺竹节32，以提高与进液管4及出液管10的连接稳定性及密封效果。
优选的，导体6与进液管4及进液孔14的内壁之间具有预定间隙，不仅便于冷却液流通，而且方便穿设导体6。
优选的，如图4所示，压接管11的端部为开口结构，不仅可作为观察孔使用，方便观察导体6的插接位置，同时可从其端部减去过长的导体6。
组装时，将密封圈2装入环形槽31内，再将宝塔接头3通过螺纹结构拧入铜排1上对应的螺纹孔内，完成宝塔接头3的安装，然后便可安装进液管4及出液管10，组装时，进液管4及出液管10需覆盖倒刺竹节32，然后利用卡箍5进行卡紧。将导体6的前端从进液管4插入，并使其前端插入压接管11内，通过压接管11观察导体6的插入位置，可使导体6更加容易插入压接管11内，不至于使导体6堵塞、弯折、损伤；同时，可以通过压接管11的端部更好确定导体6的穿入尺寸，避免压接好之后在进液管4中扭曲，或者导体6偏短致使压接尺寸不合格的情况出现。使导体6的前端与压接管11的端部齐平，然后利用压接工具或者设备对压接管11的中段进行压接，如图1、图5所示，使压接管11的中段形成内陷的压接痕7，从而对导体6实现固定以及使压接管11与导体6之间形成密封结构；或者使导体6凸出于压接管11的端部，待压接完成之后再减去多余的导体6。
以上所述仅为本发明的优选实施例，并不表示是唯一的或是限制本发明。本领域技术人员应理解，在不脱离本发明的范围情况下，对本发明进行的各种改变或同等替换，均属于本发明保护的范围。
