发明内容
本实用新型所要解决的技术问题在于针对上述现有技术中的不足,提供一种CY2型卡子结构包封云母固定电容器,其体积小、重量轻、加工及制造工艺简单、生产周期短、安装紧凑、且性能稳定、介质损耗小、可靠性指标高,适用于较大电流和功率相对较大的各种电子设备的交、直流的高频振荡线路中,径向引出使用操作简便。
为实现上述目的,本实用新型的技术方案是:一种CY2型卡子结构包封云母固定电容器,包括环氧粉末包封料层、叠加层、卡子和引出线,叠加层包括云母保护片、金属引流箔和云母介质片,金属引流箔和云母介质片交替排列叠加至规定容量,再在其两个外表面各叠加一层云母保护片构成叠加层;叠加层各层之间平行排列,卡子为两个,两个卡子分别套接在叠加层的左右两端,两个卡子的对应位置各有一个焊接点,引出线通过焊接点与卡子连接。
进一步,叠加层、卡子以及未伸出叠加层的引出线均包覆在环氧粉末包封料层内;云母介质片为天然白云母片;卡子为镀锡铜卡;引出线为镀锡紫铜线或CP线;叠加层、卡子、引线构成该云母电容器的芯组。
本实用新型与现有技术相比具有以下优点:本实用新型提供的一种CY2型卡子结构包封云母固定电容器性能稳定、体积小、重量轻、介质损耗小且可靠性指标高,电容量及时间稳定性好,既满足了部分大功率振荡电路的特殊使用要求,又扩展了云母电容器的适用范围。
以下将结合附图对本实用新型做进一步详细说明。

具体实施方式
实施例1:
为了克服现有的包封云母固定电容器结构复杂、体积大、制造工艺繁琐且云母片层间存有间隙,防潮性能差、介质损耗大、性能指标低、容量及时间稳定性差、可靠性指标低等缺陷和不足,本实施例提供了一种图3所示的一种CY2型卡子结构包封云母固定电容器,包括环氧粉末包封料层5、叠加层2、卡子1和引出线4,叠加层2包括云母保护片、金属引流箔和云母介质片,金属引流箔和云母介质片交替排列叠加至规定容量,再在其两个外表面各叠加一层云母保护片构成叠加层2,叠加层2平行排列,卡子1为两个,两个卡子1分别套接在叠加层2的左右两端,两个卡子1的对应位置各有一个焊接点3,引出线4通过焊接点3与卡子1连接。
实施例2:
在实施例1的基础上,本实施例提供的叠加层2、卡子1以及未伸出叠加层2的引出线4均包覆在环氧粉末包封料层5内;云母介质片为天然白云母片;卡子1为镀锡铜卡:引出线4为镀锡紫铜线或CP线。
本实用新型的加工制作过程是:首先在一整片云母介质上印刷电极且经过高温烘干后,对带有印刷电极的云母介质进行烧结;之后,对经烧结后的云母介质进行切片,获得带有银质内电极的云母介质片;随后,将带有银质内电极的云母介质片插入金属引流箔,叠加至规定容量后,在叠加好的叠加层两端头各套上一个卡子,并卡紧卡牢。然后再在两个卡子的对应部位焊接上镀锡铜线或CP线,该云母电容器的芯组制作完成后,内封浸渍材料并进行烘干,然后进行环氧粉末包封料包封外形。
以上所述,仅是本实用新型的较佳实施例,并非对本实用新型作任何限制,凡是根据本实用新型技术实质对以上实施例所作的任何简单修改、变更以及等效结构变化,均仍属于本实用新型技术方案的保护范围内。
