Introduction
GB/T 42710 aims to standardize the technical requirements for DC plugs and sockets for household and similar purposes to ensure that users use DC electronic appliances.
Safety during plugging and unplugging when the product is powered on.
GB/T 42710 consists of the following 2 parts.
---GB/T 42710.1 "Household and similar DC plugs and sockets - Part 1.General requirements". The purpose is to standardize household and
Technical requirements such as anti-shock protection, structural requirements, mechanical properties, and electrical properties for DC plugs and sockets with similar uses.
---GB/T 42710.2 "Household and similar DC plugs and sockets - Part 2.Types and dimensions". The purpose is to standardize household and
Types and dimensions of DC plugs and sockets for similar purposes.
This document can provide guidance for the production of DC plug and socket products for household and similar purposes, and improve the technical performance, safety and reliability of the products.
safety and ensure the safety of electricity consumption for the people.

4 Technical requirements
4.1 General
4.1.1 DC plugs and sockets for household and similar purposes are divided into two basic types. two-pole ungrounded and two-pole grounded.
4.1.2 The type, basic parameters and dimensions of DC plugs and sockets for household and similar purposes, and the arrangement of positive and negative contacts should comply with Figures 1 to 4 and 16
Provisions.
Note. The types, basic parameters and dimensions of plugs and sockets of other specifications are under consideration.
4.2 Plug
4.2.1 The shape of the plug is not specified, but the distance between the live pin of the 400V plug and the edge should not be less than 6.5mm.
Note. If the plug mating surface is not a plane, offset 1 mm from a plane passing through the highest point of the mating surface and perpendicular to the pin axis toward the plug body.
The line that intersects with the surface of the body is regarded as the edge of the plug. An example is the B value in Figure 5.
4.2.2 The live pin of the 400V plug should be equipped with an insulating sheath. The height of the insulating sheath is (9±0.5) mm. The shape of the plug insulating sheath is
The size cannot exceed the minimum size of the corresponding socket jack, and the plug can be inserted into the socket smoothly.
Plugs with insulating sheaths shall comply with the requirements of 4.2.1.
4.3 Socket
4.3.1 The distance between the live socket and the mating surface of the sockets in Figures 2 and 4 should not be less than the value specified in Table 1, see the K value indicated in Figure 6.
