技术领域
本申请涉及电配件技术领域，具体而言，涉及一种电连接器及储能系统。
背景技术
随着储能行业的快速发展，在储能系统中导线组件承载着系统内部大电流的传导，导线组件中的插头可以配合插座实现系统中的快速连接，有着高效、可靠的技术优点，但随着行业的快速发展，对于导线组件在不同情况下也有着特定使用需求。
目前，储能系统在生产、运输、设备安装过程中，为了最大程度保证安装人员及整个系统安全，在储能装置在出厂前，先将储能系统中的导线组件拆离，即将插头和插座拆离，然后将插头与导线、插座与电气装置分别进行打包发货，等到达现场后，并在整机调试前，再由现场安装人员对导线组件进行连接，即将插头与插座插接，最后实现整个高压回路导通。目前在现场实际施工操作过程中，一方面，由于储能系统中高压回路较为复杂，其中需要连接的插头与插座较多，上述插头只具有能够与插座形成电连接的电插口和能够连接线缆的导线接口，容易造成错插和误插，例如本应该插入第三行插座的插头插入了第二行插座上；另一方面，由于现场安装人员的经验和专业性参差不齐，没有足够的时间对安装人员进行系统的安装培训。因此，导致安装人员在实际操作过程中的错插、误插频发，进而引发多起系统短路事故，造成经济损失，并且会大大增加现场安装人员的安全风险。
发明内容

进一步地，插头还具有预插口，预插口被构造为能够与插座插接形成预插状态。
进一步地，对插口上设置有卡扣，预插口内设置有第一预插锁扣，电插口内设置有第一电插锁扣，卡扣能够选择性地与第一预插锁扣卡锁连接在第一锁紧位置或者与第一电插锁扣卡锁连接在第二锁紧位置。

进一步地，对插口上设置有卡扣，电插口内设置有限位件，限位件被构造为在插头处于预插状态时防止卡扣与第二槽段插接。
进一步地，卡扣包括沿对插口的周向间隔布置的预插限定部和电插引导部，插头处于预插状态时，预插限定部与限位件抵接，预插限定部和电插引导部均位于第一槽段内，插头处于电插状态时，预插限定部和电插引导部均位于第二槽段内，插头通过转动和移动的方式从预插状态转换为电插状态。
进一步地，限位件具有引导槽，插头内部具有引导空隙，引导槽的宽度小于预插限定部的长度，且不小于电插引导部的长度，引导槽被构造为在插头处于预插状态时防止预插限定部插入，并允许电插引导部插入，引导空隙的宽度大于预插限定部和电插引导部的长度，引导空隙被构造为在电插状态时允许预插限定部和电插引导部插入。

具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
参见图1、图5和图9所示，本申请提供了一种电连接器。电连接器包括：插座10，具有对插口101和设备端接口102，设备端接口102被构造为能够与电气装置30电连接，并固定在电气装置30上；插头20，具有电插口201和导线接口202，插座10能够通过对插口101和电插口201与插头20插接，导线接口202被构造为能够与导线40电连接，插头20被构造为具有能够与插座10形成绝缘连接的预插状态和与插座10形成电连接 的电插状态。
在一个实施例中，电气装置30为电池包，导线40为高压线缆。
在上述技术方案中，插头20与插座10能够通过不同的插接位置或方式，形成绝缘连接和电连接的两种插接状态。结合图13，实际应用过程中，插头20与插座10分别设置有若干个，每个插头20对应一个插座10，在储能系统运输前，先将插头20与对应的插座10插接形成绝缘连接的预插状态，在储能系统运输到现场后，再将插头20与该插座10解除预插状态，后将插头20与插座10插接形成电插状态。其中，若干个指的是两个或两个以上。
通过上述设置，安装人员只需要将某个插头20与对应的插座10解除预插状态，再将该插头20与同一个插座10二次插接形成电插状态，每一个插头20均与对应的一个插座10形成预插状态或电插状态，使得安装人员不需要再寻找某个插头20对应的插座10，减少错插、误插的情况发生。
实施例一
参见图1至图4所示，本申请的实施例一中，插头20还具有预插口203，预插口203为绝缘材质，预插口203被构造为能够与插座10插接形成预插状态。
在上述技术方案中，预插口203与对插口101插接后，由于预插口203绝缘，使得预插口203与对插口101无法导电，即使预插口203与对插口101形成预插状态。电插口201与预插口203相对设置，预插口203与对插口101解除预插状态的插接关系后，将插头20径向旋转180°后，电插口201与对插口101相对，此时将电插口201与对插口101插接形成电插状态。预插口203内沿长度方向(即第一轴线方向)开设有预插槽212，对插口101通过插入预插槽212内的方式与预插口203插接；电插口201内沿长度方向开设有电插槽211，对插口101通过插入电插槽211内的方式与电插口201插接。
通过上述设置，两个插口分别实现两种插接状态，操作简单，便于安装人员理解和实际操作。预插口203和电插口201共同形成插头20的头部，并且预插口203和电插口201相对设置，便于插头20的制作。预插槽212和电插槽211均用于为对插口101提供插接空间。
参见图1至图4所示，本申请的实施例一中，对插口101上设置有卡扣103，预插口203内设置有第一预插锁扣213，电插口201内设置有第一电插锁扣214，卡扣103能够选择性地与所述第一预插锁扣213卡锁连接在第一锁紧位置以及与所述第一电插锁扣214卡锁连接在第二锁紧位置。
在上述技术方案中，卡扣103为沿对插口101端部边缘周向延伸的环状凸起，第一预插锁扣213和第一电插锁扣214均为卡块。在对插口101与预插口203插接的过程中，卡扣103在预插槽212内移动，卡扣103从第一预插锁扣213的第一侧移动至第一预插锁扣213的第二侧，卡扣103在第一预插锁扣213的第二侧即为第一锁紧位置，此时，卡扣103与第一预插锁扣213卡锁连接，预插状态形成；在对插口101与电插口201插接的过程中，卡扣103在电插槽211内移动，卡扣103从第一电插锁扣214的第一侧移动至第一电插锁扣214的第二侧，卡扣103在第一电插锁扣214的第二侧即为第二锁紧位置，此时，卡扣103与第一电插锁扣214卡锁连接，电插状态形成。
通过上述设置，在预插口203与对插口101插接后，第一预插锁扣213与卡扣103配合实现插头20与插座10的锁定，防止在运输过程中，插头20受颠簸或碰撞等外力脱离插座10，而使预插口203失去预插的作用；在电插口201与对插口101插接后，第一电插锁扣214与卡扣103配合实现插头20与插座10的锁定，防止在高压导通过程中，插头20脱离插座10而引发系统断路故障，保证系统稳定性。
参见图1至图4所示，本申请的实施例一中，插头20的外壁设置有第一解锁件215，第一解锁件215相对于插头20的外壁可转动地设置，第一解锁件215与第一预插锁扣213和第一电插锁扣214均连接，第一解锁件215被构造为能够通过转动的方式将卡扣103解锁。
在上述技术方案中，第一解锁件215设置有两个，其中一个与第一预插锁扣213连接，
其中另一个与第一电插锁扣214连接。插头20的外壁开设有第一通孔，第一通孔与预插槽212连通，且第一通孔的轴线与第一预设轴线L1之间具有夹角，第一预插锁扣213从第一通孔穿过并位于预插槽212内，第一解锁件215与插头20的外壁枢转连接，第一预插锁扣213位于第一解锁件 215的第一端，第一解锁件215的第一端位于第一通孔内，第一预插锁扣213的第二端位于插头20的外壁，按压第一解锁件215的第二端，通过杠杆原理，第一预插锁扣213被带动离开预插槽212，并穿出第一通孔，此时对插口101能够沿预插槽212没有阻挡的顺畅移动，即第一预插锁扣213不再具备卡锁功能，对插口101能够拔出或插入预插口203。第一解锁件215的第二端与插头20的外壁之间连接有弹簧，在松开第一解锁件215时，弹簧恢复原长，带动第一解锁件215的第一端再次进入第一通孔内，连接于第一预插锁扣213的第一解锁件215的结构和动作原理分别与连接于第一电插锁扣214的第一解锁件215的结构和动作原理相同。
第一电插锁扣214朝向电插口201开口的一端具有倾斜表面，第一预插锁扣213朝向预插口203开口的一端具有倾斜表面。
通过上述设置，在预插口203与对插口101插接时，卡扣103与第一预插锁扣213的倾斜表面接触，并相对第一预插锁扣213的倾斜表面移动，通过杠杆原理，压缩第一解锁件215的第二端与插头20的外壁之间的弹簧，第一预插锁扣213穿出第一通孔，卡扣103相对第一预插锁扣213继续移动，直至第一预插锁扣213与卡扣103卡锁连接，弹簧使得在卡扣103与第一预插锁扣213连接时，不需要按压第一解锁件215，通过移动产生的推力使第一预插锁扣213解锁；在预插口203拔出对插口101时，按住第一解锁件215，待预插口203完全拔出对插口101后，松开第一解锁件215，保证预插口203与对插口101顺利解除插接关系。电插口201与对插口101插接过程中，卡扣103与第一电插锁扣214之间的卡锁过程与卡扣103和第一预插锁扣213之间的卡锁过程相同；卡扣103与第一预插锁扣213之间的解锁过程与卡扣103和第一电插锁扣214之间的解锁过程相同。
本申请的实施例一中，电插口201内部为导电材质或设置有导电片。
通过上述设置，使得电插口201与对插口101插接并通电后，两者能够实现电导通。
实施例二
实施例二与实施例一的不同之处在于：实施例二中，插头20不具备预插口203，且电插口201的结构与实施一不同。
参见图5至图8所示，本申请的实施例二中，电插口201具有相连通 的第一槽段221和第二槽段222，电插口201能够与对插口101滑动配合，以使对插口101选择性地与第一槽段221或第二槽段222插接，对插口101与第一槽段221插接形成预插状态，对插口101与第二槽段222插接形成电插状态。
在上述技术方案中，第一槽段221与第二槽段222均为环形槽，两者沿电插口201的径向布置，第一槽段221位于电插口201的深度小于第二槽段222位于电插口201的深度，对插口101通过插入深度的不同分别与第一槽段221和第二槽段222插接。
通过上述设置，对插口101与电插口201从预插状态切换为电插状态时，只需要将电插口201同向更深的插入对插口101，使对插口101从第一槽段221进入第二槽段222内，操作方便，便于安装人员的理解和实际操作。
参见图5至图8所示，本申请的一个实施例中，对插口101上设置有卡扣103，电插口201内设置有第二预插锁扣223和第二电插锁扣224，第二预插锁扣223位于第一槽段221内，第二电插锁扣224位于第二槽段222内，卡扣103能够选择性地与第二预插锁扣223卡锁连接在第一锁紧位置以及与第二电插锁扣224卡锁连接在第二锁紧位置。
在上述技术方案中，卡扣103为沿对插口101端部边缘周向延伸的环状凸起，第二预插锁扣223和第二电插锁扣224均为卡块，第二预插锁扣223为两个，两个第二预插锁扣223之间的距离与卡扣103的宽度相同，以使卡扣103能够卡锁在两个第二预插锁扣223之间。在对插口101与电插口201插接的过程中，卡扣103先在第一槽段221内移动，卡扣103从第一个第二预插锁扣223的第一侧移动至第一个第二预插锁扣223的第二侧，同时位于第二个第二预插锁扣223的第一侧，卡扣103在该位置处即为第一锁紧位置，此时，卡扣103位于两个第二预插锁扣223中间，即卡扣103与第二预插锁扣223卡锁连接，预插状态形成；卡扣103继续移动，从第二个第二预插锁扣223的第一侧移动至第二个第二预插锁扣223的第二侧，同时，卡扣103从第一槽段221进入第二槽段222，并在第二槽段222内继续移动，直至从第二电插锁扣224的第一侧移动至第二电插锁扣224的第二侧，卡扣103在第二电插锁扣224的第二侧即为第二锁紧位置， 此时，卡扣103与第二电插锁扣224卡锁连接，电插状态形成。卡扣103与第二预插锁扣223卡锁连接时，电插口201端部与对插口101端部的导电金属之间保持安全距离，保证插头20与插座10的绝缘。
通过上述设置，在电插口201与对插口101插接后，且电插口201位于第一槽段221内时，第二预插锁扣223与卡扣103配合实现插头20与插座10的锁定，防止在运输过程中，插头20受颠簸或碰撞等外力脱离插座10，而使电插口201失去预插的作用；在电插口201与对插口101插接后，且电插口201位于第二槽段222内时，第二电插锁扣224与卡扣103配合实现插头20与插座10的锁定，防止在高压导通过程中，插头20脱离插座10而引发安全事故。
参见图5至图8所示，本申请的实施例二中，插头20的外壁设置有第二解锁件226，第二解锁件226相对于插头20的外壁可移动地设置，第二解锁件226与第二预插锁扣223和第二电插锁扣224均连接，第二解锁件226被构造为能够通过滑动的方式将卡扣103解锁。
在上述技术方案中，第二预插锁扣223与第二电插锁扣224连接形成一体式的锁扣结构225，第二解锁件226为一个，第二解锁件226与锁扣结构225连接，锁扣结构225与电插口201内壁滑动配合且两者之间连接有弹簧，弹簧处于原长状态时，锁扣结构225与电插口201的内壁之间形成有间隙，第二解锁件226与插头20的外壁滑动连接，锁扣结构225受外力向下移动时，弹簧压缩，锁扣结构225压缩间隙，直至第二预插锁扣223和第二电插锁扣224离开第一槽段221和第二槽段222，此时对插口101能够沿第一槽段221和第二槽段222没有阻挡的顺畅移动，即第二预插锁扣223和第二电插锁扣224不再具备卡锁功能，对插口101能够拔出或插入电插口201；施加在第一解锁件215上的力消失后，弹簧根据弹性原理恢复原长，锁扣结构225向上移动，使第二预插锁扣223和第二电插锁扣224再次进入第一槽段221和第二槽段222。第一预插锁扣213朝向电插口201的开口的一侧具有倾斜表面。
通过上述设置，在电插口201与对插口101插接时，卡扣103与第二预插锁扣223的倾斜表面接触，并相对第二预插锁扣223的倾斜表面移动，压缩弹簧，第二预插锁扣223离开第一槽段221，卡扣103相对第二预插 锁扣223继续移动，直至第二预插锁扣223与卡扣103卡锁连接，弹簧使得在卡扣103与第二预插锁扣223连接时，不需要按压第二解锁件226，通过移动产生的推力使第二预插锁扣223解锁；在对插口101需要进入第二槽段222或电插口201需要拔出对插口101时，向下滑动第二解锁件226，第二解锁件226带动锁扣结构225压缩间隙，同时弹簧压缩，待第二预插锁扣223离开第一槽段221，且第二电插锁扣224离开第二槽段222后，对插口101能够相对于第一槽段221和第二槽段222自由移动，待对插口101插入第二槽段222或电插口201拔出对插口101后，松开第二解锁件226，弹簧通过自身弹性原理恢复原长，第二预插锁扣223和第二电插锁扣224再次进入第一槽段221和第二槽段222。
参见图5至图8所示，本申请的实施例二中，对插口101外壁设置有标识条104，卡扣103位于第一锁紧位置时，标识条104位于插头20外部，卡扣103位于第二锁紧位置时，标识条104位于插头20内部。
在上述技术方案中，标识条104为环形，且具有荧光色(比如，绿色)，标识条104套设在对插口101上。在电插口201与对插口101插接形成预插状态时，即卡扣103位于第一锁紧位置时，标识条104位于电插口201外部，能够被安装人员看见，提醒安装人员此时插头处于预插状态；在电插口201与对插口101插接形成电插状态时，即卡扣103位于第二锁紧位置时，标识条104位于电插口201内部，安装人员无法看到标识条104。因此，标识条104用于使安装人员判断对插口101与电插口201是处于预插状态还是电插状态。
通过上述设置，使得进行预插工作的安装人员能够通过标识条104判断对插口101与电插口201是否处于预插状态，防止进行预插工作的安装人员将对插口101与电插口201插接形成电插状态，引发安全事故；同样，也使得进行电插工作的安装人员能够通过标识条104判断对插口101与电插口201是否处于电插状态，防止进行电插工作的安装人员将对插口101与电插口201插接形成预插状态，无法导通。
实施例三
实施例三与实施例二的不同之处在于：插座10的卡扣103的具体结构、插头20具备限位件231以及仅具有一个第二预插锁扣223。
参见图9至图12所示，本申请的实施例三中，电插口201内设置有限位件231，卡扣103包括沿对插口101的周向间隔布置的预插限定部131和电插引导部132，限位件231被构造为能够阻挡预插限定部131，且不阻挡电插引导部132，预插限定部131被构造为能够与第二电插锁扣224卡锁连接，电插引导部132被构造为能够与第二预插锁扣223卡锁连接。
参见图9至图12所示，本申请的实施例三中，限位件231包括至少两个限位块，两个限位块之间形成引导槽232，预插限定部131和电插引导部132均为沿对插口101的端部周向间隔布置的筋条，预插限定部131的长度大于电插引导部132的长度，引导槽232的宽度小于预插限定部131的长度，且不小于电插引导部132的长度，以使预插限定部131无法穿过引导槽232，且电插引导部132能够穿过引导槽232。
在上述技术方案中，限位件231包括四个限位块，每两个限位块为一组，两组限位块相对设置在电插口201内；每组限位块中的两个限位块之间形成引导槽232，两组限位块之间形成引导空隙233，引导槽232和引导空隙233均与第一槽段221和第二槽段222重合。预插限定部131为两个相对设置的筋条，电插引导部132也为两个相对设置的筋条，预插限定部131和电插引导部132沿对插口101的端部周向间隔交错布置，预插限定部131的长度小于引导空隙233的长度，使预插限定部131能够从引导空隙233穿入至第二槽段222内。
电插口201与对插口101形成预插状态时，预插限定部131正对限位块，电插口201插入对插口101，直至预插限定部131与限位块接触时，电插口201无法继续移动，此时第二预插锁扣223与电插引导部132卡锁连接，将电插口201与对插口101锁定在预插状态；电插口201与对插口101形成电插状态时，将插头20轴向旋转90°，电插引导部132正对引导槽232，且预插限定部131正对引导空隙233，电插口201插入对插口101，直至电插引导部132穿过引导槽232，且预插限定部131穿过引导空隙233，此时第二电插锁扣224与预插限定部131卡锁连接，将电插口201与对插口101锁定在电插状态。
实施例三中的第二解锁件226的结构和原理与实施例二相同。
通过上述设置，限位件231和卡扣103的结构设计，实现预插的准确 限位，保证进行预插工作的安装人员无法将电插口201与对插口101插接形成电插状态，进而保证安全性。
参见图9至图12所示，本申请的实施例三中，第二预插锁扣223设置为一个，配合限位件231实现与卡扣103的卡锁连接。
参见图13所示，本申请还提供了一种储能系统。该储能系统包括电气装置30、导线40、以及上述电连接器，插头20和插座10均为多个，多个插头20与多个插座10一一对应设置。
需要说明的是，多个是指两个或两个以上。电气装置30由六组电池组成，每个电池组与两个插座10电连接。导线40为若干根，两个电池组之间通过一根导线40连接，每一根导线40的两端分别电连接两个插头20。
从以上的描述中，可以看出，本申请的上述的实施例实现了如下技术效果：主要通过改变插头的结构，增加插头的插口或改变插头的插入深度，进而使插头与插座能够插接形成绝缘连接的预插状态，通过专业人员先将插头与插座预插，现场的安装人员只需要将插头与插座的预插状态转换为电插状态，就能够实现导线40的连接，原理简单，操作方便，减少错插、误插的情况发生。
显然，上述所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本申请保护的范围。
需要注意的是，这里所使用的术语仅是为了描述具体实施方式，而非意图限制根据本申请的示例性实施方式。如在这里所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式，此外，还应当理解的是，当在本说明书中使用术语“包含”和/或“包括”时，其指明存在特征、步骤、工作、器件、组件和/或它们的组合。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
