Abstract

一种能够平衡全封闭罩壳内外部气压的防水透气螺塞体。它是把防水透气膜放入螺塞中,与端盖通过超声波铆接为一体。在将硅橡胶垫圈放入螺塞体中,然后将铆接好的端盖旋入螺塞体中,最后装上防水胶圈。对于薄壁壳体,可以另加螺母紧固。

Description

防水透气螺塞 
所属技术领域
本实用新型涉及的是一种防水透气的螺塞体结构,特别是针对解决户外灯具防水透气的一种螺塞体结构。 
技术背景
目前,公知的户外灯具及电子产品的防水防护是采用全封闭方式,但户外灯具等产品因其运行和关闭,内部会由于温度变化而使气压变化较大,壳体内气体便会从薄弱部分排出腔外;产品断电后,随着内部温度的逐渐降低而产生负压,外面的雨水和潮湿空气等介质,便会进入腔体内部,长期聚积将会导致产品的电性能失效。 
发明内容
为了解决采用全封闭方式密封的缺陷,本实用新型提供了一种可以平衡壳体内外气压的防水透气螺塞。 
本实用新型解决其技术问题采用的技术方案是:把防水透气膜放入螺塞中,与端盖通过超声波铆接为一体。再将硅橡胶垫圈放入螺塞体中,然后将铆接好的端盖旋入螺塞体中,最后装上防水胶圈。对于薄壁壳体,可以另加螺母紧固。通过本防水透气螺塞来平衡罩壳内外部气压,达到防水透气的效果。 
本实用新型的有益效果是,使罩壳内外部气压平衡,达到防水透气的效果。并且结构简单紧凑,安装方便快捷,效果好。 
附图说明
下面结合附图和实施例对本实用新型进一步说明。 
图1是本实用新型的外观图。 
图2是防水透气螺塞的端面图。 
图3是图2的剖视图。

具体实施方式
在图3中,一、把防水透气膜3放入螺塞4中,与端盖5通过超声波铆接为一体。二、再将硅橡胶垫圈2放入螺塞体1中,然后将铆接好的端盖旋入螺塞体1中。三、最后装上防水胶圈6。
