1、 It should be designed with a mechanism that prevents the wire from sliding out of the designated position when tightened with screws or inserted.

2、 Measures should be taken to prevent the connectors from loosening during use.

3、 Appropriate contact pressure should be ensured to prevent damage to the function of the connecting wire, even when the connecting wire is directly clamped with multiple strands of wire.

4、 Whether to apply contact pressure through insulating materials, and when applying contact pressure through insulating materials, a grounding continuity test should be conducted for assessment.

5、 Permanent connector connection method

6、 Plug-in connector

1. Each connector should have at least two connection points, each independent of the other contact point.

2. If the factory connector is still internally energized when disconnected, the connector should be equipped with an interlocking device to prevent disconnection when energized, or a sign should be set up. For small parts, they can be marked near them.
