GB 2099.1-1996 Plugs and sockets for household and similar purposes Part 1: General requirements
Some standard content:
GB2099.1-1996
This standard is equivalent to IEC881-1 (1991 second edition); "Plugs and sockets for household and similar purposes Part 1: General requirements". Plugs and sockets for household and similar purposes are widely used products, mainly used by non-professionals in homes, offices, hotels, farms, light industrial factories, etc., and are connected to electrical appliances and equipment in most cases. The quality and safety performance of their products determine the safety of people's lives, property and the surrounding environment. At the same time, considering the current situation of plug and socket types and sizes in my country and the actual situation in the world, we have adopted IEC884-1 in terms of technical content and the same writing format as IEC.884-1 to formulate this standard. The main differences between this standard and IEC884-1 are as follows: a: This standard is suitable for my country's plug and socket system. IEC884-1 is a universal international standard, which is suitable for both flat plug and socket systems and shaped plug and socket systems. When we adopted IEC 884-1 to formulate this standard, we made appropriate inclusions to some of the contents, namely, we deleted the contents about the round plug barrel seat system, including the contents about non-solid pins (Article 14.2 and Figure 31) and the plug insulating sheath (Chapter 20, Chapter 21, Article 24.7, 30, Figure 23, Figure 26, Figure 29, Figure 30). At the same time, we changed the schematic diagrams of the flat pin plug in IEC 884-1: Figure 1, Figure 22, Figure 25, Figure 28, to the schematic diagrams of the flat pin plug, but the technical requirements and test methods are consistent with IEC 884-1. This standard is suitable for the introduction of my country's flat socket system.
b, this standard is suitable for my country's socket power supply, voltage and frequency ratings. There are basically three voltage ratings in IEC884-1: 130V, 250V and 440V. In this standard, only 250V and 440V are retained, which are compatible with my country's relevant national standards. The rated current values in IEC884-1 are 2.5A6A, 10A, 16A and 32A. my country's single-phase and two-phase socket current ratings are 6A, 104: 16A, 32A. Therefore, we deleted the relevant content of 2.5A in this standard. There are two power frequencies in IEC 884-1, 50 Hz and 60 Hz. In this standard, we only take 50Hz which is suitable for my country.
, Suitable for my country's geographical location and ambient temperature. Some parts of my country are in tropical areas with high ambient temperatures, while IEC standards mainly come from European and American countries with high latitudes. Therefore, IFC884-1 stipulates that the ambient temperature of plugs and sockets is usually not more than 25°C, and occasionally reaches 35°C. According to the geographical and climatic characteristics of my country, we stipulate in GB2099.1: The ambient temperature of plugs and sockets is usually not more than 35, and occasionally reaches 40C. For tests of certain clauses that need to be evaluated under harsher conditions, IFC884-1 stipulates that the test should be conducted at 35°C, while GB2099.1 stipulates that the test should be conducted at 40°C.
Compared with GB2099-80, this standard mainly adds protection against electric shock and connection. The provisions of local measures have increased the requirements and tests for the structure of sockets and plugs, and also increased the requirements and tests for screws, current-carrying parts and their connections, hatching distances, electrical clearances and distances through insulation, and abnormal heat, flame resistance and leakage resistance. The addition of these contents makes the new plug and socket standard more scientific and stricter. This standard mainly stipulates the general technical requirements for plugs and sockets for household and similar purposes. Its types, basic parameters and dimensions can be found in the relevant national standards of my country.
This standard replaces GB209980 from the date of implementation. This standard was proposed and submitted by the National Technical Committee for Standardization of Electrical Accessories. This standard was drafted by the National Standard Revision Group for Plugs and Sockets for Household and Similar Purposes. The drafting unit of this standard: Guangzhou Electric Science Research Institute of the Ministry of Machinery Industry, the main drafters of this standard; Gong Yue, Yue Shijie, Luo Huaiping, Sun Fangneng, Yan Cuiqin, He Weien, Gu Qixiang.

1] According to the actual situation in my country, the types, basic parameters and dimensions of plugs and sockets for household and similar purposes should comply with CB 1002 2. The tolerance grade of plug and socket gauges conforms to GB180079 General Tolerance and Fit, Standard Tolerance and Basic Deviation 3. GB1U02.31 From a safety perspective, we do not allow barrel heads and sockets with different poles to interlock, so the words "except for barrel sockets specially manufactured to allow interlocking with barrel heads with fewer poles, but without any danger" are deleted in this paragraph. GB 2099. 1—1996
If the plug is a plug of Class 0 equipment, it should not be possible to insert the plug into a socket with a grounding sleeve; the plug of Class I equipment should not be able to be inserted into a socket designed for plugging Class II equipment. Compliance shall be checked by observation or manual test using a gauge in accordance with 9.1. If there is any doubt about the above non-insertable performance, it shall be checked by applying force for 1 min with an appropriate gauge. The force applied is 150N for electrical accessories with a rated current not exceeding 16A and 250N for other electrical accessories. If the elastic material or thermoplastic material used will affect the test results, this test shall be carried out in an environment of 40℃+2-, and the electrical accessories and gauges shall be at this temperature.
Note: For hard materials, such as thermosetting resins, ceramic materials, etc., as long as they meet the relevant plug and socket type and basic parameter standards, they will definitely meet this requirement.
10 Protection against electric shock
10.1 The socket shall be designed so that when the plug is installed and wired as required for proper use, live parts are not accessible, even after parts which can be removed without tools have been removed. Live parts of the plug shall not be accessible when the plug is partially or fully engaged with the socket-outlet. Compliance shall be checked by inspection and, if necessary, by the following test: Install the plug as for normal use and install the conductor with the smallest cross-section. The test shall be repeated with the conductor with the largest cross-section as specified in Table 3.
For socket-outlets, apply the standard test finger shown in Figure 2 to each possible position F. For plugs, apply the test finger to each possible position when the plug is partially or fully engaged with the socket-outlet. The contact of the test finger with the relevant part is shown by a voltage indicator of not less than 40 V but not more than 50 V. For electrical accessories which may fail to meet the requirements due to the use of elastic or thermoplastic materials, the test shall be carried out at an ambient temperature of ℃ ± 2, and the electrical accessories shall also reach this temperature. During this additional test, the accessory shall be subjected to a force of 75 N for 1 min, applied by the end of a straight, jointless test finger of the same size as the standard test finger. The test finger, equipped with the above-specified test finger, is applied to all positions where deformation of the insulating material would impair the safety of the accessory, but not to diaphragms. When this additional test is carried out on thin-wall knockout holes, the force applied by the test finger to the thin-wall knockout hole is 10.
During this test, the compression deformation of the accessory and its related mounting parts shall not cause excessive changes in the dimensions specified in the relevant standards to ensure safety, and no live parts shall become accessible. Each sample of the plug or portable socket is then pressed between two flat surfaces with a force of 150 N for 5 min in the manner shown in Figure 22. The sample is removed from the test device for 15 min and then checked again. The deformation of the test partner shall not cause excessive changes in the dimensions specified in the relevant standards to ensure safety. 10.2 When the electrical accessories are wired and installed according to the normal use requirements, the parts that are still easily accessible (except for the small screws and the like that are isolated from the auxiliary parts and used to fix the base and cover or plate of the socket) shall be made of insulating materials. However, the cover or cover plate of the fixed socket can be made of metal if it meets the requirements of 10.2.1 or 10.2.2. 0.2.1 The metal cover or cover plate shall be protected by the additional insulation formed by the insulating pad or insulating barrier fixed to the cover or plate or the body of the electrical accessory. These insulating pads or barriers shall be reliably fixed and can only be removed if they are permanently damaged; or they shall only be used in the correct position. Note:
1_Since part of my country has a subtropical climate, considering the harsh conditions, the test environment temperature for electrical accessories made of elastic or thermoplastic materials is changed to 40C±21. Here, IFC884-1 stipulates 35:12: The following similar provisions for the test temperature of electrical accessories made of elastic or thermoplastic materials are the same.
2 In my country, the size of the head and seat must comply with the relevant national standards of my country. Therefore, Article 9.3 of C884-1 is not applicable to this standard.
