Abstract

一种单相二极插头,既能插二极插座,又能插三 极插座;和现有插头一样,插头铜极和导线相连后注 塑于塑料体中,但塑料体开有V形缺口,并可沿剖线 分开,用塑料量略少于现有插头,且由于本插头的结 构特征,使之避免现有插头经常出现与插座接触不良 的情况。

Description

本实用新型是关于一种改进的单相6A以下二极插头,该插头能方便地插入二极或三极插座。
现有单相二极插头插不进三极插座,在使用时常碰到这样的情况,墙上的插座是三极的,用电器插头是二极,人们常用钢丝钳将插头两铜插销硬转过一个角度,但这既容易损坏插头,又使插头铜极与插座接触不良。在现有资料中,也有能插二极或三极插座的插头,但因结构复杂而未能实施。
本实用新型的目的是提供一种改进的二极插头,它结构简单,成本和现有二极插头一致,既能插二极插座又能插三极插座。
本实用新型的任务是以如下方式完成的:如图1,两铜插销1分别和导线7相连后注塑在塑料体2中,2的一边去掉一部分,形成一V型缺口3,参见图2,塑料体2中上部可沿剖开线6完全分开,或在V型缺口3的顶点4处相连,剖开线6的剖开深度达缺口3的下顶点8处,图2为插头和二极插座相配时的顶部型状,当需插三极插座时,用手捏塑料体2的两边,使V型缺口3闭合,参见图3,剖开线6分开成一个大V字型。根据国家标准,二极插座的插套中心距离为12.7±0.15(mm),三极插座的火、零两插套中心距离为13.7±0.1(mm)。,所以V型缺口3的顶点4(见图2)距塑料体2的中心点5距离定为2.6~2.8(mm),使插头在图3型状时,插销的中心距离刚好和三极插座相配。
该插头在生产出厂时的型状可既不是剖开线6完全闭合,也不是V型缺口3完全闭合,而处于一中间状态,即剖开线6的顶端分开角度为25°~30°之间,最好为29°~31°,这样无论插二极或三极插座时,塑料体2均有一个向中间状态的恢复力,该力使插头的铜插销与插座的铜插套接触良好,避免现有普通插头经常出现与插座接触不良的情况。
插头的外观也可以制成如图4的型状,塑料体2为圆型(见图5)。

Claims (2)

1、一种单相二极插头,两铜插销1分别和导线7相连后注塑于塑料体2中,其特征是:塑料体2有一V型缺口3,塑料体2的中上部沿剖开线6完全分开,或在缺口3的顶点4处相连,剖开线6的剖开深度达缺口3的下顶点8处,剖开线6顶端分开的角度在25°~30°之间,塑料体2的中心点5与顶点4的距离为2.6~2.8mm之间。
2、根据权利要求1所述二极插头,其特征是:剖开线6顶端分开角度为29°~31°。
