This standard applies to plugs, sockets and connectors with an AC voltage of 50Hz or 60Hz, a rated voltage not exceeding 440V or a DC rated voltage not exceeding 220V, and a rated current of 16 to 125A, used in general ships, refrigerated containers and docks. However, it is not applicable to places with explosion hazards. 2 Reference standards GB2099 Packaging storage and transportation pictorial signs Technical conditions for single-phase and three-phase plugs and sockets GB2423.10 GB2423.16 GB2423.17 Basic environmental test regulations for electrical and electronic products are test A: low temperature test method Basic environmental test regulations for electrical and electronic products Basic environmental test regulations for electrical and electronic products Basic environmental test regulations for electrical and electronic products Basic environmental test regulations for electrical and electronic products Basic environmental test procedures for electronic products GB4942.2 Protection level of low-voltage electrical enclosures 3 Terms 3.1 Interlocking device Test B: High temperature test method Test Db: Alternating damp heat test method Test Fc: Vibration (sinusoidal) test method Test J: Mildew test method Test Ka: Salt mildew test method It refers to a mechanical structure that prevents the plug pin from being energized before the plug and socket or connector are plugged in, and can also prevent the plug pin from being pulled out when energized. 3.2 Retention device It refers to a mechanical structure that keeps the plug or connector in the normal working position when it is plugged in to prevent accidental disengagement. 4 Product classification 4.1 See Table 1 for basic parameters. Approved by the State Administration of Technical Supervision on April 20, 1990, and implemented on December 12, 1990 Rated current 3P+N++ 312321-90 50 or 60 50 or 60 50 or 60 Rated voltage 110 or 220 250 or 440 Grounding contact Clock position Note: ① The position of the grounding contact is determined by comparing the front of the socket with the clock face, setting the key slot position at 6 o'clock (6h), and then according to the clock position of the grounding socket, see Appendix A (supplement). 250V or 440V is only for refrigerated containers. 4.2 The arrangement diagram of the socket and the pin of the plug is shown in Figures 1 and 2.
