Abstract

一种扣式双电层电容器的绝缘性胶圈,属于高容量双电层电容器设计制造领域，涉及一种扣式双电层电容器的绝缘性胶圈。以工程塑料为材料，采用模具浇铸法制造，在绝缘性胶圈上平面留有2－8个浇注口凸起；浇注口凸起均匀分布在绝缘性胶圈上;胶圈整体密度一致，硬度一致，降低了产品断裂的几率，留有浇注口，在胶圈上表面产生凸起，这些突起很方便的将模具与产品分离，避免了产品变形，也提高了产品的产率。

Description

一种扣式双电层电容器绝缘性胶圈
所属技术领域
本实用新型属于高容量双电层电容器设计制造领域，涉及一种扣式双电层电容器的绝缘性胶圈。
背景技术
扣式双电层电容器一般拥有高能量密度，比锂二次电池充放电频率优秀，以其所拥有的友好的特征而被作为手提机器中的备份电源使用。
常规方法制造的扣式双电层电容器如图5所示。其结构与制造方法具体来说为：在上盖部和下盖部中间使用被导电性粘结剂附着的分极性电极，经过高温干燥再充分的注入分解液，夹入隔膜纸后，在上盖部和下盖部之间夹入用于隔离及密封的中间胶圈。 
目前，扣式双电层电容器中的绝缘性胶圈采用高性能工程塑胶制造，其耐热性能突出。但是，高性能工程塑胶的流动性不好，容易在模具内急速硬化，导致在形成圆形之前断掉或发生尾端部分的密度变弱的现象，时有胶圈在模具中抽不出来的现象，强行抽出容易变型，增大了双电层电容器发生漏液的可能性。
实用新型内容
本实用新型的目的就在于克服上述现有技术的缺陷，提供一种保证胶圈所有部分密度均匀，强度一致，不易发生断裂，不易发生变形的扣式双电层电容器的绝缘性胶圈。
为实现上述实用新型目的所采取的技术方案为：
以工程塑料为材料，采用模具浇铸法制造，在绝缘性胶圈上平面留有2－8个浇注口凸起；
浇注口凸起均匀分布在绝缘性胶圈上。
本实用新型通过在浇注模具设置2－8个浇注口，同时浇注，塑料硬化时间基本一致，从而可以保证胶圈整体密度一致，硬度一致，降低了产品断裂的几率，留有浇注口，在胶圈上表面产生凸起，这些突起很方便的将模具与产品分离，避免了产品变形，也提高了产品的产率。 
附图说明
图1为依据本实用新型方法生产的胶圈的结构示意简图；
图2为图3的俯视图；
图3为扣式双电层电容器的结构示意简图。
图中：上盖部11、下盖部12、上分极性电极21、下分极性电极22、分解液24、隔膜纸23、胶圈13。 
具体实施方式
以工程塑料为材料，采用模具浇铸制造，在绝缘性胶圈（13）上平面留有8个浇注口凸起(9)；浇注口凸起(9)均匀分布在绝缘性胶圈(13)上平面。
