This standard specifies the requirements for wire maintenance components used for household and similar general equipment. This standard does not apply to industrial wire assemblies (i.e. wire assemblies with industrial plugs and connectors that comply with GB11918 and GB11919). It also does not apply to extended wire assemblies. Note: According to the definition of this standard, the power cord with a detachable plug and connector is not a "cord set". However, considering that they are similar to "cord sets" and have the same purpose, it is recommended that the power cord with a detachable plug and connector should adopt the requirements of this standard as much as possible as long as it is reasonable. 2 Terminology
Cord set
A cord set refers to an assembly consisting of a flexible cable or cord with a non-detachable plug and a non-detachable connector, which is used to connect an appliance or equipment to a power source.
Note: For the definitions of "non-detachable plug" and "non-detachable connector", refer to GB2099.1 and ZBK32003 respectively. The difference between a cord set and an extended cord set is that the latter has a removable socket but no connector, and cannot directly connect an appliance or equipment to a power source.
Non-detachable connectors with a section of wire connected are sometimes called "incomplete wire assemblies". For the requirements of such incomplete wire assemblies, see GB2099.1.
3 General requirements
The design and manufacture of wire assemblies should ensure that the performance of the wire assemblies is reliable during normal use and does not pose a hazard to users and the surrounding environment. All specified tests should be carried out to check whether they meet this requirement. Approved by the State Administration of Technical Supervision on May 23, 1996 and implemented on April 1, 1997
4 Technical requirements
4.1 Technical requirements for components
The plug of the wire assembly should comply with GB2099.1.GB 15934-1996
The connector of the wire assembly should comply with ZBK32003. The flexible cables and cords of wire and cable components shall comply with GR5023.3, GB5013.2, GB3958 and IEC227-51. The plugs, connectors and flexible cables or cords shall be checked by the tests specified in the corresponding standards. During the test of the plug (or connector), the influence on the connector (or plug) shall be ignored. When the stranded wire is subjected to contact pressure, the ends of the stranded wire shall not be consolidated by soldering unless the design of the fastening components can avoid poor contact caused by cold flow of flux. Note: The type, parameters and dimensions of the plug of the wire assembly shall comply with the following types in GR102\: Figure 1: 6A or 10A two-pole plug
Figure 3: 6A or 10A two-pole with grounding headwww.bzxz.net
Figure 5: 16A two-pole with grounding plug
4.2 Requirements for the entire assembly
4.2.1 Rated voltage
The rated voltage of the connector and the flexible relay or cord shall not be less than the rated voltage of the corresponding plug. 4.2.2 Rated current
The rated current of the plug shall not be less than the rated current of the corresponding connector. 4.2.3 Classification of equipment
The classification of the protection against electric shock of the plug and connector should be the same as the classification of the protection against electric shock of the equipment to be connected. The classification standard of the protection against electric shock of the equipment is shown in GB/T12501.
A wire assembly equipped with a connector for Class I equipment can be equipped with a head for Class 1 equipment in GB1002. 4.2.4 Marking
Plugs and connectors shall be marked in accordance with the corresponding marking provisions. Wire assemblies that are not delivered with the appliance and whose plugs and connectors are not manufactured by the same manufacturer shall also be marked with the name and trademark of the manufacturer of the complete wire assembly or the store responsible for sales. Such markings shall not be marked on the packaging.
Note: Such manufacturer or store name and trademark may be marked on the sheath of the wire assembly. Plugs, connectors or wire assemblies used to connect to class 2 equipment shall not be marked with class structure codes (double boxes). 4.2.5 Type of flexible cord
The type of flexible cable or cord of a wire assembly shall not be lighter than the type determined by the connector of the wire assembly, and its cross-sectional area shall not be less than the value specified in the following table.

1- TFC 799 stipulates that the plug types that can be used on the wire assembly are TFC 83: household and community plugs and sockets A1-15, A5-1, R2, C2b, C3b, C4.C5, C6. According to the specific situation in my country, the type, parameters and dimensions of the plugs used in the wire assembly should comply with GB The provisions in Figures 1, 3 and 5 of 1002, ..com Rated current

Note; 1) See sub-clause 4.2.6.
2) For flexible cables or cords not exceeding 2 m in length, the minimum cross-sectional area may be 0.5 mm2. Compliance with the requirements of 4.2.1 to 4.2.5 shall be checked by inspection. 4.2.6 Length of flexible cord
0.75mtn3
If the cross-sectional area of ​​the flexible cord of the cord assembly is equal to or less than 0.5mm*, the length of the flexible cord shall not exceed 2m. For: 227IFC.41, the cross-sectional area of ​​the flat gold-skinned flexible cord is less than 0.5mm. The length of the flexible cord is measured between the two points where the flexible cable or cord sheath enters the plug and the connector. If there is no clear end point, the length of the flexible cord is measured at the point where its outer diameter is 1mm greater than the outer diameter of the flexible cord. For fan-shaped cords, this increased outer diameter is measured along the long axis of the flexible cord. Compliance with the requirements of this subclause is checked by observation and measurement. 5 Electrical continuity and polarity
For cord assemblies used in polarized systems, electrical continuity between the plug pins of each pole and the barrel of the connector shall be ensured. Compliance with this requirement shall be determined by measurement. Note: (1) The lightest type of flexible cord connected to a connector with a rated current of 0.2.A used in class 1 equipment specified in IEC799 is 227IEC41. Since there is a type of flat gold-skinned soft wire number corresponding to 227IFX:41 in China, we directly quote 227IEC.41. This number is specified in the IEC 227-5 standard. Please refer to the translation of IEC 227-5 by Shanghai Cable Research Institute. GB15934-1996
