技术领域
本申请涉及电池技术领域，具体涉及一种隔离板组件、电池模组、电池包、用电装置。
背景技术
电池模组或电池包的输出极相对于电芯组件的距离并不固定，当远离时，输出极过长，运输和锁附时容易开裂失效。
发明内容
鉴于上述问题，本申请提供一种隔离板组件、电池模组、电池包、用电装置，可对输出极提供更稳定的连接，防止输出极出现开裂失效的问题出现。
第一方面，本申请提供了一种隔离板组件，包括：
隔离板，设有多个汇流排安装位；
汇流排，每个汇流排安装位上安装有汇流排；
输出极，具有第一固定部和第二固定部，第一固定部与至少一个汇流排电连接；

本申请实施例的技术方案中，绝缘板与输出极连接，隔离板与绝缘板连接，输出极与汇流排电连接，可以加强输出极的固定，有效防止输出极在运输和锁附时开裂失效的问题出现。
在一些实施例中，第二连接部与第二固定部粘接设置，且二者之间设有胶层。
由此，可使输出极更稳固地连接在绝缘板上，以防止运输和锁附时出现较大力矩而引起输出极开裂失效的问题出现。
在一些实施例中，隔离板包括：
第一绝缘板体；
第二绝缘板体，与第一绝缘板体叠置，汇流排设置在第一绝缘板体和第二绝缘板体之间，第一连接部位于第一绝缘板体和第二绝缘板体之间。

在一些实施例中，第一连接部与第一绝缘板体连接；和/或第一连接部与第二绝缘板体连接。
由此，可进一步提高绝缘板与隔离板连接的可靠性。
在一些实施例中，多个汇流排中的至少一个汇流排将第一连接部压在第一绝缘板体或第二绝缘板体上。
由此，可以更加牢固地对绝缘板固定。
在一些实施例中，第二固定部为板状结构，第二固定部横向设置于第二连接部的上方。
由此，可以减小输出极沿隔离板的厚度方向的体积，使电池模组或电池包更加紧凑。

除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同；本文中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请；本申请的说明书和权利要求书及上述附图说明中的术语“包括”和“具有”以及它们的任何变形，意图在于覆盖不排他的包含。
在本申请实施例的描述中，技术术语“第一”“第二”等仅用于区别不同对象，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量、特定顺序或主次关系。在本申请实施例的描述中，“多个”的含义是两个以上，除非另有明确具体的限定。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人 员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
在本申请实施例的描述中，术语“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
在本申请实施例的描述中，术语“多个”指的是两个以上(包括两个)，同理，“多组”指的是两组以上(包括两组)，“多片”指的是两片以上(包括两片)。
在本申请实施例的描述中，技术术语“中心”“纵向”“横向”“长度”“宽度”“厚度”“上”“下”“前”“后”“左”“右”“竖直”“水平”“顶”“底”“内”“外”“顺时针”“逆时针”“轴向”“径向”“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请实施例和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请实施例的限制。

申请人注意到，电池模组或电池包的输出极与输出排电连接后，会悬出一部分，成为悬臂结构，在运输和锁附时，悬臂相对输出极与输出排连接位置较远，存在较大的受力，在运输和锁附时容易造成输出极开裂失效。
为了解决上述问题，申请人研究发现，可以在输出极的第二固定部332与隔离板31之间设置绝缘板，输出极的第二固定部332与隔离板31分别与绝缘板固定，可以对输出极起到加强的作用，可避免运输和锁附时容易造成输出极开裂失效的问题发生。

在一些实施例中，请参照图6，绝缘板34的上表面设有注胶槽342，沿隔离板31的厚度方向A，注胶槽342的槽底比储胶槽343的槽底浅，注胶槽342设有排胶口，排胶口与储胶槽343连通，用于向储胶槽343排胶。
具体可选的，可在绝缘板34的上表面设有具有开口的围挡344，围挡344的内部空间可以形成注胶槽342，围挡344的开口作为排胶口。也可以不设置围挡344，在绝缘板34的上表面开设凹槽作为注胶槽342。
注胶槽342的槽底比储胶槽343的槽底浅，二者的底面形成阶梯，当向注胶槽342 内注胶时，胶水可以自高处向低处流入储胶槽343内，实现输出极33与绝缘板34的粘接。注胶槽342的设置可以更方便绝缘板34与输出极33的粘接，无需将隔离板31和绝缘板34先涂胶后再安装在一起，方便操作。
在一些实施例中，请参照图6，注胶孔341位于注胶槽342内。
注胶孔341的顶部高度可以大于、等于或小于注胶槽342的顶部边沿的高度。
示例性地，注胶孔341的顶部高度可以大于注胶槽342顶部边沿的高度。可以先向注胶孔341内注胶，待注胶孔341内注满胶水后，胶水从注胶孔341溢出至注胶槽342，并从注胶槽342流入储胶槽343内。也可以分别向注胶孔341和注胶槽342内注胶。
示例性地，注胶孔341的顶部高度可以等于注胶槽342的顶部边沿的高度。可以先向注胶孔341内注胶，待注胶孔341内注满胶水后，胶水从注胶孔341溢出至注胶槽342，并从注胶槽342流入储胶槽343内。也可以分别向注胶孔341和注胶槽342内注胶。
示例性地，注胶孔341的顶部高度小于注胶槽342的顶部边沿的高度。可以先向注胶槽342内注入胶水，胶水同时流向注胶孔341和储胶槽343。
可以向注胶孔341或注胶槽342或同时向注胶孔341或注胶槽342内注胶，实现绝缘板34与电池单体20以及绝缘板34与输出极33的粘接固定，使操作更加简单方便。
在一些实施例中，请参照图6，注胶孔341内设有加强筋。
加强筋可以为但不限于十字加强筋，也可以为X形等。
由此，可实现胶水和绝缘板34的连接，提升绝缘板34的强度。
在一些实施例中，请参照图6，绝缘板34上设有注胶观察窗345，注胶观察窗345沿绝缘板34的厚度方向贯通绝缘板34。
注胶观察窗345可设置在注胶孔341的一侧，从注胶孔341内向电池单体20内注入胶水，胶水会横向流动，当胶水流至注胶观察窗345时，可以确定胶水已经过多，可停止注胶。
由此，可以通过注胶观察窗345确定注胶孔341流向电池单体20的胶量是否过多。
以下实施例为了方便说明，以本申请一些实施例的一种电池模组为例进行说明。
本申请的电池模组包括上述隔离板组件和至少一个电池单体20。其中，隔离板组件位于电池单体20的顶部，电池单体20与绝缘板34连接。
电池单体20与绝缘板34连接指电池单体20与绝缘板34相对固定不能移动。
本申请的电池模组包括上述隔离板组件的技术特征，所起效果与上述相同，在此 不再赘述。
在一些实施例中，在一些实施例中，电池单体20的顶部与绝缘板34的底部粘接固定。
具体可选的，可通过向绝缘板34的注胶孔341内注胶，实现电池单体20与绝缘板34的粘接固定。
由此，可以使绝缘板34更加牢固，进一步使输出极33的第二固定部332更可靠地固定，防止输出极33的第二固定部332在运输和锁附时开裂失效的问题出现。
以下实施例为了方便说明，以本申请一些实施例的一种电池包为例进行说明。
本申请的电池包包括电池模组。
具体的，电池模组设置在电池包的箱体内。
由于电池模组包括上述隔离板组件的技术特征，所起效果与上述相同，在此不再赘述。
