第一楔形面104、第一下嵌凸台105和第二下嵌凸台106便于密封件结构1与防脱盖2、插头外壳3的连接。
本申请还提供一种电缆连接结构，包括前述的高压连接器插头，高压连接器插头插合连接于一高压连接器插座。
所述高压连接器插头和所述高压连接器插座插合后，所述密封件结构1压缩后的体积占所述密封件结构1初始的体积比为50％-85％。
为了验证密封件结构1压缩后的体积占密封件结构1初始体积的比值对密封件本体的使用寿命以及对插头插入插座插入力的影响，申请人选用相同的密封件结构1和相同规格的插头，不同规格的插座，对插头和插座插拔次数以及对插头和插座的插入力进行测试，在本实施例中，不同规格的插座与相同规格的插头及相同的密封件本体插接时可以实现密封件结构1的不同的压缩比值。
防水等级的测试方法使用防水5级的测试方法为：喷水试验；
试验设备：喷嘴的喷水口内径为6.3mm试验条件：使插头和插座插合后的连接结构至喷水口相距为2.5m～3m，水流量为12.5L/min(750L/h)。
试验时间：按被检插头和插座插合后的电缆连接结构的外壳表面积计算，每平方米为1min(不包括安装面积)最少3min。在本实施例中，申请人设定使用防水等级为5级的测试方法，插头和插座插合后，密封件结构1达到防水效果为合格。
插入力的测试方法为：使用推拉力计测试作用于插头，待插头插入插座插合后，得出的推拉力计读数，在本实施例中，申请人设定插头和插座插入力设定小于95N为合格。
表1：密封件结构1压缩后的体积占密封件结构1初始的体积的百分比对密封件本体是否防水的影响和对插入力的影响。
Figure PCTCN2022131381-appb-000001
从表1中可以看出，当密封件结构1压缩后的体积占密封件结构1初始的体积的百分比大于85时，插头和插座插合后的电缆连接结构的密封件本体不防水，不能够满足使用要求；当密封件结构1压缩后的体积占密封件结构1初始的体积的百分比小于50时，插头和插座的插入力大于95N,不能满足合格值要求。所以申请人选定密封件结构1压缩后的体积占密封件结构1初始的体积的百分比为50-85％。
IP是国际用来认定防护等级的代号，IP等级由两个数字所组成，IPXX中第一个数字X表示防尘；第二个数字X由表示防水，数字越大表示防护等级越佳。
防尘等级一共为8个等级，分别为0-7级；0级为无防护，无特殊的防护；1级为防止大于50mm之物体侵入，防止人体因不慎碰到电气设备内部零件；2级为防止大于12.5mm之物体侵入，防止手指碰到电气设备内部零件；3级为防止大于2.5mm之物体侵入，防止直径大于2.5mm的工具、电线或物体侵入；4级为防止大于1.0mm之物体侵入，防止直径大于1.0mm的蚊蝇、昆虫或物体侵入；5级为防尘，无法完全防止灰尘侵入，但侵入灰尘量不会影响电气正常运作；6级为尘密，完全防止灰尘侵入；
防水等级为9个等级，分别为0-8级；0级为无防护，对水或湿气无特殊的防护；1级为防止水滴浸入，垂直落下的水滴不会对电器造成损坏；2级为倾斜15度时仍可防止水滴浸入，当电气设备由垂直倾斜至15度时，滴水不会对电器造成损坏；3级为防止喷洒的水浸入，防止雨水或垂直的夹角小于60度的方向所喷洒之水侵入电器而造成损坏；4级为防止飞溅的水浸入，防止各方向飞溅而来的水侵入；5 级为防止喷射的水浸入，防止来自各个方向由喷嘴射出的水侵入电器而造成损坏；6级为防止大浪的水侵入，防止因大浪的侵袭而造成损坏；7级为防止浸水时的水侵入，电气设备浸入水中一定时间或水压在一定的标准以下，可确保不因浸水而造成损坏；8级为防止沉没时水的浸入，电气设备无期限的沉没在一定水压的条件下，可确保不因浸水而造成损坏。
高压连接器插头内采用密封件结构1，能够有效防止水或颗粒进入高压连接器插头内。通过本申请的设计，密封件结构1的防尘等级可以达到4级、5级、6级，防水等级可以达到5级、6级、7级以及8级，具体的可以选用IP67,IP6K9K，满足多种使用环境的需要。
由上所述，本申请的高压连接器插头、密封件结构和电缆连接结构具有如下有益效果：
本申请提供的密封件结构，能在插头和插座的插合过程中形成多级密封，密封更牢固可靠，增强了插头插座配合的稳定性和电气的安全性；密封件结构的多级密封凸起结构与插座内表面相接触，其使得插座和插头的接触面积小，插头插拔阻力小，密封更牢固可靠；
本申请的高压连接器插头内，防脱盖2与密封件结构的结合面为斜面，第一楔形面104内嵌在防脱盖里，防脱盖向下压紧密封件结构，保持其不扭曲不变形，防止插座与插头插合时密封件结构扭曲变形；装配防脱盖时，防脱盖的第二楔形面201少许加力在密封件结构的第一楔形面104上，使密封件结构产生塑性变形，能增强密封件结构的密封效果；
本申请的高压连接器插头内，密封件本体的第一下嵌凸台105和第二下嵌凸台106交替内嵌于插头外壳的第一连接槽301和第二连接槽302内，防脱盖2的压力传导在此处有一定的密封效果，实现密封件结构与插头外壳的密封连接，防止插头与插座插合时密封件结构上下窜动扭曲变形，同时第一连接槽301和第二连接槽302的设计可以防止插头和插座插合时密封件结构的变形，第一下嵌凸台105与第二下嵌凸台106交替分布预防密封件的转动，减少密封失效的发生；防脱盖2的倒钩紧紧卡在插头外壳的第三连接槽401内，密封件结构受到防脱盖2的下压力，增强了密封件结构的密封效果。
以上所述仅为本申请示意性的具体实施方式，并非用以限定本申请的范围。任何本领域的技术人员，在不脱离本申请的构思和原则的前提下所作出的等同变化与 修改，均应属于本申请保护的范围。
