Abstract

本实用新型公开了一种电能表的端钮盒盖,其主要特点是在盒盖的下端面上开设有接线孔,该孔与电能表的进线孔在空间位置上是交错的。这种特殊设计的电能表的端钮盒盖,使用户无法插接、调换和改动电能表的接线,有效地避免了窃电现象的发生。

Description

电能表的端钮盒盖
本实用新型涉及一种防窃电装置,特别涉及一种电能表的端钮盒盖。
目前,我国每年由于窃电而造成的电力能源的浪费是非常巨大的,为此人们研究出了许多防窃电装置,例如防窃电电能表。这种电能表的确具有防窃电作用,但成本较高,推广困难,不可能把当前广泛使用的老式电能表全部替换掉。而老式电能表端钮盒盖的接线孔与电能表的进线孔成直线分布,不具有防窃电作用。经检索有关文献,尚未发现有与本实用新型相同或相似的记载。
本实用新型的目的就是提供一种具有防窃电作用的电能表的端钮盒盖。
本实用新型的技术解决方案很简单,就是在盒盖的下端面上开设接线孔,使该孔与电能表的进线位置在空间产生错移,也就是使导线在经过接线孔后,在前后方向和左右方向上产生错位,避免了用户插接、调换和改动电能表的接线,有效地防止了窃电现象的发生。
本实用新型设计构思独特,制造工艺简单,在老式电能表上换上本实用新型后,可防止用户分流窃电、调换接线窃电、二次接地窃电等一切在电能表上做手段的窃电,具有成本低廉、推广容易的优点。
图1是本实用新型的结构主视图;
图2是图1中的A-A向结构剖视图。
图中标号3是铅封孔,可采用本人的另一项专利申请防拆卸型封印压封胎模对端钮盒盖加封、防窃电效果更佳。
