Description

一种大功率充电枪专用DC+与DC-串冷液冷端子连接管组件
技术领域
本发明涉及大功率充电桩技术领域，具体的说是一种大功率充电桩专用液冷端子DC+和DC-之间的液冷端子连接管组件。
背景技术
公知的，随着世界发达国家对新能源电动汽车的推广应用，国内新能源电动汽车行业也朝气蓬勃，其发展速度日新月异，由于新能源电动汽车没有尾气排放，其环保无污染，因此燃油汽车终将要被环保型的电动汽车所取代，而伴随着电动汽车的迅猛发展，便捷的充电站也终将会取代现在传统的加油站；目前，用于电动汽车的充电站，硬件设施基本都是中功率充电桩，直流电压750伏,输出电流小于250安,以普通车型的电动公交车充电为例，充满全车电瓶至少需要三个小时。中功率充电桩的充电效率不高,国内正在研发的大功率充电桩,它的技术参数:直流充电电压1000～1500伏，输出电流500～600安培，若使用大功率充电桩充电，以普通车型的电动公交车充电为例，充满全车电瓶只需要10分钟就够了；大功率充电桩充电效率高,是未来充电站的主流产品。
上述设计的大功率充电桩专用液冷电缆DC+和DC-,每根软体导线的截面仅为35～60平方毫米,其比中功率充电桩干式集成电缆的70平方毫米还要小，且整体电缆外径尺寸也仅为39毫米,与传统的干式集成电缆的外径一样,不仅如此,该大功率充电桩专用液冷电缆还能够安全地承载600安培的电流，保障大功率充电使用，避免充电桩工作过程中电缆和充电枪端子DC+和DC-出现过热现象；然而，在实际应用中，上述大功率充电桩专用液冷电缆软体导线若与现有中功率充电枪的干式充电枪端子配接，由于现有中功率充电枪端子不是液冷结构，其根本无法构成冷却液循环流动的通路，因此，现需要设计一种能够有效与上述大功率充电桩专用液冷电缆软体导线配套使用的充电枪专用液冷端子DC+和DC-，而大功率充电枪专用液冷端子绝缘连接管是安装在大功率充电枪内的一个关键部件,是充电枪专用液冷端子DC+和DC-之间的液冷通道。由绝缘连接管实现冷却液从一根电缆进,到另一根电缆出的串接冷却。
发明内容
本发明的目的是提供一种大功率充电桩专用液冷端子DC+和DC-之间的绝缘连接管。
本发明为解决上述技术问题采用的技术方案为：
一种大功率充电枪专用DC+与DC-串冷液冷端子连接管组件,连接充电枪内的DC+和DC-两个液冷端子，所述DC+和DC-两个液冷端子上均设置900弯管贯通口，两个900弯管贯通口相互对应，且其中一个900弯管贯通口端部设置有内螺纹，另一个900弯管贯通口端部设置有外螺纹；绝缘连接管包括绝缘导管、绝缘锁紧螺母、喇叭型螺母和密封圈，其绝缘导管为中空结构，该中空部分为冷却液通道，导管的两端端面上设置有环形槽，环形槽内设置有密封圈；绝缘导管的一端设置有与其中一个液冷端子的900弯管贯通口相配合的外螺纹，其配合处通过绝缘螺母锁紧；绝缘导管的另一端设置为倒锥型结构, 通过喇叭型螺母的内螺纹与另一个900弯管贯通口的外螺纹旋紧配合，喇叭型螺母的内锥面压紧配合导管的外锥面。
为了进一步改进技术方案，本发明所述导管内冷却液通道内的冷却液为纯净水、变压器油、变压器硅油或氟化液。
为了进一步改进技术方案，本发明所述导管的材质为聚四氟乙烯。
与现有技术相比，本发明的有益效果是：本发明所述的大功率充电枪专用液冷端子，在充电枪内的DC+和DC-液冷端子的中部分别设置一个凸出的900弯管贯通口，并通过绝缘连接管将两个900弯管贯通口对应连通起来，当两个充电枪液冷端子分别与背景技术中所述大功率充电桩专用液冷电缆的软体导线对应连接，冷却液由一根液冷电缆电极进入，冷却液(可以是:纯净水、变压器油、变压器硅油、氟化液…等)由(红色)电缆＋DC的快接通过电极,进入绝缘套管,穿过软体导线,到达充电枪液冷端子内腔底部。通过绝缘连接管进入(黑色)电缆－DC的充电枪液冷端子内腔底部,进入绝缘套管,穿过软体导线,进入电极到达快接,再回到冷却装置，从而形成冷却液的循环。
