插头,插座及连接器基础知识

第一部分：插头，插座及连接器基础知识

??基本符号及含义

A——安培（ampere）

V——伏特 (volt)

~ ——交流电（alternating current）

———直流电（direct current）

L ——火线（line contact）

）

earthing contact）

IEC规定标识顺序为：先额定电流，后额定电压，再电源，额定电流和额定电压之间可用斜线或水平线分开。

For the marking with rated current and rated voltage the figures may be used alone. These figures shall be placed on one line separated by an oblique line or the figure for rated current shall be placed above the figure for rated voltage, separated by a horizontal line.

The marking for the nature of supply shall be placed next to the marking for rated current and rated voltage.

Note: The marking for current, voltage and nature of supply may be, for example, as follows (以下为IEC的规定标识例子)：

16A 440V~ or 16/440~ or~

第二部分：插头（Plug）

主要内容：插头的种类

1．按接线极来区分：

a．两极插头

●　无接地触头的可逆式两极插头，一般有两种，一种Pin脚为矩形，另一Pin为圆形，

如下图所示：

●无接地触头的不可逆式两极插头，一般有以下四种，如下图所示：

●　带接地的两极插头，一般有以下几种

b．三极插头

●　三极不带地线插头

●　三极带地线插头

圆Pin脚为地线Pin.

●　三极带零线插头

上方的Pin脚为零线Pin.

2．按额定电流和额电电压来分类：

●　15A 125V插头

●　16A 250V 插头

●　60A 250V 插头

●　15A 220V 插头

因各国使用电压不同，按此方式来分类的插头种类繁多。

第三部分：Connector

??　概述

1．Connector是随计算机和集成电路的发展而产生并被广泛运用，相对于插头来说，Connector为一新生事物，因而有国际通用的标准，无地域差异。

2．此文是以IEC60320为依据，IEC60320是一本两极带地线或不带地线的通用Connector国际标准。

3．IEC60320的有关Connector规定介绍。

●　This part of IEC60320 is applicable to two—pole applicable couplers

for a.c. only, with or without earthing contact, with a rated voltage not

exceeding 250V and a rated current not exceeding 16A, for household

and similar general purposes and intended for the connection of a

supply cord to electrical appliances or other equipment for 50Hz or 60

Hz supply. IEC60320是一本两极带地线或不带地线的用于交流回

路的Connector国际标准，此Connector适用最大额定交流电压为

250V，最大额定交流电流为16A，是一种通用的，作为50Hz或60Hz

电源和电器及电气设备之间的连接。

●　Standard ratings：The standard rated voltage is 250V, the standard rated

currents are 0,2A, 2,5A, 6A, 10A, and 16A. 额定电压为250V, 额定交

流电流为0,2A, 2,5A, 6A, 10A, 16A.

0,2A 250V appliance coupler for classⅡequipment and cold condition．　

2,5A 250V appliance coupler for classⅠequipment and cold condition.

●　Marking：

Connectors shall be marked with: rated current in amperes, except for 0,2A Connectors; rated voltage in volts; symbol for nature of supply; name, trademark or identification mark of the maker or responsible vendor; type reference. Connector需标明额定电流（除0,2A）；额定电压；电源；生产商或销售商的商标；型号。

●　Classification (分类)：

1.According to maximum pin temperature at the base of the pins of

the corresponding appliance inlet, 根据器具的Pin脚的温度：
