GB 17465.2-1998 Appliance couplers for household and similar purposes Part 2: Interconnection couplers for household and similar equipment
Some standard content:
GB17465.21998
This standard is equivalent to IEC320-2-2 (1990 first edition) "Appliance couplers for household and similar purposes Part 2: Interconnection couplers for household and similar equipment" and the first revision in November 1994 and the second revision in June 1997. It should be used in conjunction with GB17465.1-1998 "Appliance couplers for household and similar purposes Part 1, General requirements". Five-way couplers for household and similar equipment are widely used in household electrical appliances and connected to electrical appliances or equipment. In most cases, they are used by non-professionals. The quality and safety of the product directly affect people's lives, property and the safety of the surrounding environment. In order to improve the usability and safety and reliability of products, and to make products have a unified inspection method and safety requirements, we have equivalently adopted IEC320-2-2:1990 in terms of technical content. In terms of writing format, we have added a chapter of "reference standards" because it is used in conjunction with GB17465.1-1998. The remaining chapters and articles completely correspond to IEC 320-2-2:1990, and the serial number is added with 1IEC320-2-2:1994. The first revision was mainly made to Figure 2E and Figure 2F. The second revision of IEC320-2-2:1997 was mainly to expand from 10A to 16A, and the chapters and articles were modified accordingly, adding Figures 2I~2I. and Figures 101~104. The differences between this standard and IEC 320-2-2 are as follows: 1. Some areas in my country have a subtropical climate with a high ambient temperature. The IEC standard comes from European and American countries with a high latitude. Therefore, IEC320-2-2 stipulates that the ambient temperature of the equipment interconnection coupler usually does not exceed 25°C and occasionally reaches 35°C. According to the characteristics of my country's geographical environment and climate, this standard stipulates that the working ambient temperature of the equipment interconnection coupler usually does not exceed 35°C and occasionally reaches 40°C. 2. In order to correspond to GB17465.11998 "Appliance Couplers for Household and Similar Purposes Part 1 General Requirements", this standard adds a chapter "*References" in the text, and the referenced standards of IEC320-2-2:1990 are placed in the preface, and their contents are the same. This standard is proposed by the Ministry of Machinery Industry.
This standard is under the jurisdiction of the National Technical Committee for Standardization of Electrical Accessories. The drafting unit of this standard is Guangzhou Electric Science Research Institute of the Ministry of Machinery Industry. The main drafters of this standard are Huang Shiguan and He Weien. This standard is entrusted to the National Technical Committee for Standardization of Electrical Accessories for interpretation. GB17465.2-1998

GB 17465.1-1998 Clause 19 is applicable with the following changes. The interconnecting coupler shall have adequate breaking capacity. For appliance inlets, compliance is checked by the following test, in which the appliance inlet is mounted in a test apparatus similar to that shown in Figure 14 and fitted with a plug connector having a polished steel pin and the dimensions being those specified in the relevant Figures 2A to 21. The appliance inlet shall be positioned so that the plane through the axis of the socket is halfway and the earthing socket, if any, is at its highest. Insert and remove the plug connector into the appliance socket 50 times (100 strokes) at a rate of 30 strokes per minute. The connection method is shown in Figure 15. The test voltage is 275 V and the test current is 1.25 times the rated current. For 10 A and 16 A For electrical accessories, the power factor shall be at least (.95; for 2.5A appliance sockets, the power factor shall be (0.6 ± 0.05). The grounding circuit, if any, is not energized. When the switch is halfway through the stroke, turn the selector switch C that connects the grounding circuit and easily accessible metal parts to one pole of the power supply (switch to one pole of the power supply). If an air-core inductor is used, a resistor that can shunt 1% of the current flowing through the inductor should be connected in parallel with the air-core inductor. Iron-core inductors can also be used if the current is formed into a substantially sinusoidal waveform. During the test, no flashover or sustained arcing shall occur between live parts of different polarities or between such parts and parts of the grounding circuit (if any). After the test, the specimen shall not have any damage that may affect its future use, nor shall the insertion hole of the plug have any serious damage. Note: If in doubt, the test shall be repeated with a new plug. The new plug shall be tested within the effective length. The surface roughness within the range shall not exceed 0.8umm, and the new plug shall be installed in the plug connector of the test device. If this set of samples can withstand the retest with the new plug, the appliance socket shall be deemed to meet the above requirements. 2 strokes refer to the first insertion or removal of the plug connector. 3 The plug connector is not tested for breaking capacity. 20 Normal operation
Chapter 20 of GB17465.1--1998 is applicable with the following changes. The five-way coupler shall be able to withstand the mechanical, electrical and thermal stresses occurring in normal use without excessive wear or other harmful effects.
