为了更好地理解本申请，下面结合图1至图14对本申请实施例的端子保护装置及电池模组进行详细描述。
图1为本申请实施例提供的一种电池模组的装配图，图2为图1的爆炸结构示意图。电池模组包括：多个单体电池20，多个单体电池20沿第一方向(图2中的X方向)层叠设置；输出极60，电连接于单体电池20；端板40，沿第一方向设置于多个单体电池20的一侧，端板40上设置有凹槽41，且凹槽41和输出极60位置相对应；端子保护装置10，卡设于凹槽41，且端子保护装置10上开设有输入口121，以使输出极60能够 由输入口121伸入端子保护装置10内部。
电池模组的设置方式不仅限于此，例如电池模组还包括上盖30，沿第三方向(图1中的Z方向)设置于多个单体电池20的一侧，输出极60由上盖30和单体电池20之间伸出，凹槽41位于端板40朝向上盖30的一侧，令端子保护装置10卡设于凹槽41时能够和输出极60的位置相对应。
在本申请实施例的电池模组中，电池模组的输出极60伸入端子保护装置10内部，受端子保护装置10的保护，防止输出极60外露带来安全隐患。
请一并参阅图3，当多个电池模组相互连接时，用于连接多个电池模组的电连接件50可以伸入端子保护装置10，并与端子保护装置10内的输出极60相连接，从而完成各电池模组之间的互连。
端子保护装置10的设置方式有多种，如图4和图5所示，端子保护装置10包括底座100，底座100具有底部110及连接于底部110周侧的侧板120，侧板120与底部110一并形成容纳腔130，侧板120上开设有输入口121，输入口121用于穿设输出极60，即用于穿设输出极60的输入口121开设于侧板120。
请一并参阅图6，为了提高输出极60和端子保护装置10相对位置的稳定性，输出极60上设置有贯穿的通孔61，底部110设置有导电紧固件112，导电紧固件112例如为导电螺母，令螺栓等连接件能够穿过通孔61与导电紧固件112电连接，并将输出极60固定于底部110。
为了提高端子保护装置10和端板40之间相对位置的稳定性，底座100的底部110沿第三方向(图2中的Z方向)延伸成型，底部110在第二方向(图2中的Y方向)上的至少一侧设置有凸台111，令端子保护装置10通过凸台111可以和端板40的凹槽41过盈配合，从而提高端子保护装置10和端板40之间相对位置的稳定性。在一些可选的实施例中，底座100的底部110在沿第二方向相对的两侧均设置有凸台111，令底座100受力更加均匀，同时能够进一步保证端子保护装置10和端板40之间相对位置的稳定性。
进一步的，侧板120还开设有接通口122，以使外部的电连接件50能 够穿过接通口122与容纳腔130内的输出极60连接。
侧板120的设置方式有多种，例如，侧板120在接通口122处不设置遮挡物，当多个电池模组相互连接时，电连接件50直接通过接通口122和容纳腔130内的输出极60连接。
在一些可选的实施例中，接通口122处设置有护板140，护板140可拆卸地盖合于接通口122。在这些可选的实施例中，当多个电池模组无需相互连接时，例如电池模组在运输过程中，护板140盖合于接通口122处，防止容纳腔130内的输出极60与外部电连接而发生漏电事故，提高电池模组运输过程中的安全性能。当电池模组需要相互连接时，将护板140由接通口122处拆下，令外部的电连接件50能够穿过接通口122与输出极60连接。
其中，护板140可拆卸地盖合于接通口122处是指在护板140的拆卸过程中不会对护板140或侧板120等结构造成破坏的连接方式，例如护板140卡设于接通口122处等。护板140可拆卸地设置于接通口122，拆卸护板140时不会对端子保护装置10的其他部位造成结构性损坏，提高端子保护装置10的使用寿命，防止端子保护装置10损坏导致带电的部分输出极60或电连接件50外露，进而进一步提高电池模组的安全性能。
请一并参阅图7和图8，护板140和接通口122可拆卸连接的方式有多种，在一些可选的实施例中，侧板120朝向接通口122的内壁面具有在第三方向上延伸的滑槽125，护板140包括本体部141及位于本体部141相对两边缘的滑板142，滑板142相对滑槽125可移动设置，以使护板140通过滑板142可拆卸地设置于滑槽125。
在这些可选的实施例中，通过滑板142相对滑槽125移动实现护板140和侧板120之间的可拆卸连接。滑板142相对滑槽125可移动设置。当输出极60无需跟电连接件50相连时，护板140通过滑板142限位于滑槽125内；当输出极60需要跟电连接件50相连时，护板140通过滑板142滑出滑槽125，进而完成护板140的拆卸。且在护板140的拆卸过程中，不会对侧板120或护板140造成结构上的破坏，操作简单方便。
在一些可选的实施例中，护板140的设置方式不仅限于此，滑板142 在第三方向具有相对的两个端部、及位于两个端部之间的中部，在由至少一个端部至中部的方向上，滑板142在第一方向上的尺寸具有增大的趋势。
在这些可选的实施例中，滑板142在其端部至中部的方向上尺寸增大，令中部的尺寸较大而端部的尺寸较小，在滑板142利用其端部进入滑槽125时，便于滑板142和滑槽125的相互对准，提高端子保护装置10的装配速度。
护板140具有增大趋势的设置方式有多种，例如在两个端部中的至少一者上设置有导向面142a，在由中部至端部的方向上导向面142a沿靠近本体部141的方向倾斜。
如图7和图8所示，滑板142相对的两个端部均设置有导向面142a，且主体部两边缘的两个滑板142上相对的两个端部均设置有导向面142a，一个护板140上具有四个导向面142a。在护板140的装配过程中，可以从护板140在第三方向上的任一端滑入滑槽125内，进一步提高端子保护装置10的装配速度。
接通口122的数量在此不做限定，在一些可选的实施例中，接通口122为两个以上，两个以上的接通口122在侧板120的周向上间隔分布，每个接通口122内均设置有护板140。
在这些可选的实施例中，接通口122为两个以上，且分别位于侧板120的不同位置。在多个电池模组的连接中，便于电连接件50从侧板120的不同位置伸入容纳腔130内，电连接件50可以选择令其自身延伸路径最小的接通口122处伸入容纳腔130内，从而节省电连接件50的用料，并能够简化电连接件50的结构，减少电连接件50所占空间。
进一步的，两个以上的接通口122和输入口121在侧板120的周向上间隔分布，且输入口121位于侧板120朝向输出极60的一侧，令输出极60延伸较小的距离即可伸入容纳腔130，同时优化接通口122和输入口121的分布，减小侧板120的体积。
请一并参阅图9至图12，在一些可选的实施例中，容纳腔130还具有和底部110相对设置的开口131，开口131和接通口122连通，开口131 处还盖设有顶盖200，顶盖200可拆卸地设置于开口131，以通过顶盖200将护板140限位于接通口122。
在这些可选的实施例中，容纳腔130的开口131处设置有顶盖200，且接通口122和开口131连通，能够通过顶盖200将护板140限位于接通口122处。当多个电池模组无需相互连接时，将顶盖200盖设于开口131处，以通过顶盖200将护板140限位于接通口122处，保证护板140和侧板120相对位置的稳定性，及电池模组在运输过程中的安全性能。当多个电池模组需要相互连接时，将顶盖200由开口131处拆下，令护板140能够从开口131处取下，便于多个电池模组相互连接。
通过顶盖200将侧板120限位于接通口122的方式有多种，在一些可选的实施例中，当护板140利用滑板142可移动地设置于侧板120上的滑槽125时，接通口122和开口131连通，滑槽125延伸至开口131处。当输出极60无需跟电连接件50相连时，护板140可以从开口131处滑入滑槽125内，继而将顶盖200盖设于开口131处，防止护板140由开口131处脱落。当输出极60需要跟电连接件50相连时，将顶盖200由开口131处拆卸，令护板140可以通过开口131从滑槽125内滑出，完成护板140的拆卸。
在另一些可选的实施例中，当护板140利用其它方式可拆卸地设置于接通口122处时，可以通过置于开口131处的顶盖200向护板140提供沿第三方向上的限位，而将护板140限位于接通口122。
侧板120和顶盖200的设置方式不仅限于此，在一些可选的实施例中，侧板120还包括在其周向上和接通口122间隔设置的连接口123；顶盖200包括盖板210及由盖板210伸出的遮挡板220，盖板210盖设于开口131，遮挡板220对应遮挡连接口123；其中，遮挡板220上开设有沿第二方向延伸的豁口230，以通过豁口230能够将位于豁口230远离盖板210一侧的至少部分遮挡板220去除，使外部的电连接件50能够穿过连接口123与输出极60连接。
在这些可选的实施例中，侧板120上还设置有连接口123，令电连接件50可以通过连接口123和接通口122中的任一者和输出极60连接。顶 盖200上伸出有遮挡板220，遮挡板220能够遮挡连接口123，且遮挡板220上开设有豁口230，通过豁口230能够将至少部分遮挡板220去除，从而令连接口123敞开。通过设置连接口123，进一步增加了电连接件50在端子保护装置10上连接位置的个数，令电连接件50可以从不同方向、不同位置与容纳腔130内的输出极60连接。
在多个电池模组无需相互连接时，遮挡板220能够对连接口123起到遮挡作用，提高多个电池模组在运输过程中的安全性能；当多个电池模组相互连接且电连接件50需要从连接口123和输出极60连接时，将部分遮挡板220去除，令电连接件50能够由连接口123伸入容纳腔130并与输出极60相互连接。
侧板120的形状在此不做限定，例如侧板120大致呈四棱柱状，连接口123和输入口121沿第一方向相对设置于侧板120，接通口122有两个，两个接通口122沿第二方向相对设置于侧板120。如此，令两个接通口122和一个连接口123开设于侧板120不同位置，并分别朝向不同方向。如图3、图13和图14所示，电连接件50可以由三个不同方向分别连接于输出极60。
可以理解的是，在上述实施例中，通过豁口230能够将至少部分遮挡板220去除的设置方式有多种，在一些可选的实施例中，遮挡板220包括在第三方向上相继分布的分离部221和连接部222、以及连接分离部221和连接部222的剪角部223，分离部221位于豁口230远离盖板210的一侧，连接部222位于豁口230和盖板210之间，第三方向和第二方向相交；剪角部223的横截面在分离部221至连接部222的方向上具有减小的趋势。
在这些可选的实施例中，可以通过豁口230和剪角部223将分离部221由连接部222上掰下，从而令连接口123敞开。由于剪角部223的横截面在分离部221至连接部222的方向上具有减小的趋势，因此在对遮挡板220施力去除分离部221时，剪角部223靠近连接部222的部位容易被折断，不易在连接部222的端面留下多余的剪角部223，能够提高连接部222端面的平整性，当电连接件50伸入连接口123时，能够减小连接部 222对电连接件50的摩擦损耗，提高电连接件50的使用寿命。
其中，剪角部223的横截面可以是剪角部223上被X-Y所在平面截得的第一平面，也可以是剪角部223上被X-Z所在平面截得的第二平面。在一些可选的实施例中，剪角部223的横截面既包括第一平面，也包括第二平面，进一步保证分离部221被掰下后，连接部222端面的平整性。
在上述任一实施例中，顶盖200可拆卸地设置于开口131处的方式有多种，例如，顶盖200和侧板120中的一者上设置有第一卡扣，另一者上设置有和第一卡扣相适配的第二卡扣，令顶盖200和侧板120利用第一卡扣和第二卡扣相互卡扣连接。
其中，第一卡扣和第二卡扣的设置方式在此不做限定，例如第一卡扣为卡槽124，第二卡扣为凸起240，当第二卡扣为凸起240时，凸起240为两个，以使其中一个凸起240卡扣于卡槽124，另一个凸起240止挡于侧板120顶部或顶盖200顶部。
如图6所示，侧板120在第一方向上相对的两个内侧面均设置有卡槽124；顶盖200在第一方向上相对的两个外表面均设置有两个凸起240，两个凸起240在第三方向上间隔分布，以使其中一个凸起240卡扣于卡槽124，另一个凸起240止挡于侧板120的顶部。
在这些可选的实施例中，侧板120的两个内侧面上设置有卡槽124，顶盖200上与侧板120的两个内侧面对应的两个外表面上均设置有两个凸起240，凸起240和卡槽124相对应，令侧板120和顶盖200通过卡槽124、凸起240及材料本身的弹性相互卡扣连接。其中，每个外表面均设置有两个凸起240，其中一个凸起240卡扣于卡槽124，另一个凸起240止挡于侧板120的顶部，能够进一步提高顶盖200和侧板120相对位置的稳定性。
当顶盖200上设置有两个凸起240，两个凸起240沿第三方向间隔设置时，位于顶盖200上靠近侧板120一侧的凸起240上设置有引导面，令该凸起240在靠近侧板120的方向上尺寸具有减小的趋势，便于通过该引导面将凸起240卡扣于卡槽124内。
可以理解的是，凸起240和卡槽124的设置位置不仅限于此，例如还 可以在侧板120在第一方向上相对的两个内侧面均设置有两个凸起240，在顶盖200在第一方向上相对的两个外表面均设置有卡槽124，令其中一个凸起240卡扣于卡槽124，另一个凸起240止挡于顶盖200的顶面。
进一步的，当顶盖200和侧板120利用第一卡扣和第二卡扣相互卡扣连接时，为了提高顶盖200在第一方向上的弹性变形，顶盖200的盖板210包括在第一方向上相互连接的平面部211和回弹部212，回弹部212呈U型，回弹部212具有在第一方向上间隔设置的两侧臂212a、及连接于两侧臂212a之间的底臂212b。
在这些可选的实施例中，在顶盖200卡扣于侧板120时，利用两侧臂212a的形变能够提高顶盖200在第一方向上的变形量，防止将顶盖200卡扣于侧板120，或将顶盖200由侧板120上分离时，造成顶盖200或侧板120的损坏，提高顶盖200和侧板120的使用寿命。
平面部211和回弹部212的数量及设置方式在此不做限定，例如平面部211可以为两个，两个平面部211分设于回弹部212在第一方向上的两侧，且两个平面部211分别通过两侧臂212a连接于回弹部212。
在一些可选的实施例中，为了简化顶盖200的成型方式，盖板210包括在第一方向上相继分布的平面部211和回弹部212，回弹部212利用其中一个侧臂212a连接于平面部211。
当顶盖200在第一方向上相对的两个外表面均设置有两个凸起240时，平面部211远离回弹部212的侧边具有朝向底座100延伸的侧部，两个凸起240设置于侧部的外表面；回弹部212的其中一个侧臂212a连接于平面部211，另一个侧臂212a的外表面设置有两个凸起240。
回弹部212的个数在此不做限定，回弹部212可以为一个或两个以上，当回弹部212为两个以上时，两个以上的回弹部212沿第二方向间隔分布，两个以上的回弹部212的其中一个侧臂212a均连接于平面部211，两个以上的回弹部212的另一个侧臂212a的外表面均设置有两个凸起240。
可以理解的是，顶盖200的设置方式不仅限于此，例如当卡槽124设置于顶盖200时，侧臂212a的外表面设置有卡槽124，且回弹部212远离 平面部211的侧臂212a外表面也设置有卡槽124。
本申请可以以其他的具体形式实现，而不脱离其精神和本质特征。例如，特定实施例中所描述的算法可以被修改，而系统体系结构并不脱离本申请的基本精神。因此，当前的实施例在所有方面都被看作是示例性的而非限定性的，本申请的范围由所附权利要求而非上述描述定义，并且，落入权利要求的含义和等同物的范围内的全部改变从而都被包括在本申请的范围之中。
