Engineer Desso says that welding is a common method of wire joining in which two wires are joined together by molten metal. In M12 connectors, solder connections are typically used to connect wires and contacts. The welded connection has the advantages of firm connection and stable electrical performance, and is suitable for occasions with high requirements for electrical connection. However, there are some disadvantages of welded connections, such as the possibility of thermal stress during the welding process that causes deformation of the wire, and the fact that the wire is not easy to replace after welding.
The crimp connection is a mechanical connection by pressing the wire and the contact together with a special crimping tool. The crimp connection has the advantages of reliable connection and simple operation, and is suitable for high-volume production and repair scenarios. In addition, the crimp connection has high electrical and weather resistance, which can meet the needs of use in harsh environments. However, there is also a potential risk of crimped wires that are not firmly connected or loose.
Threaded connection is to set threads on wires and contacts, and realize the tight connection between wires and contacts by rotation. The threaded connection has the advantages of stable connection, easy disassembly and replacement, and is suitable for occasions where frequent wire replacement is required. In addition, the threaded connection has high weather resistance and vibration resistance, making it suitable for harsh environments and use scenarios. However, threaded connections also have disadvantages such as cumbersome connection process and high skill requirements for operators.
The mating connection is to insert the wire into the jack of the connector, and the connection between the wire and the contact is realized through the spring blade or pin inside the jack. The plug-in connection has the advantages of fast connection and simple operation, and is suitable for occasions where fast plugging and unplugging of wires is required. In addition, the plug-in connection also has good electrical performance and weather resistance, which can meet the needs of general industrial environments. However, there are also potential risks such as poor plugging and easy loosening of plugging connections, and it is necessary to pay attention to the control of plugging depth and plugging strength.
The advantages of welded connection are firm connection and stable electrical performance; The disadvantages are that thermal stress may occur during the welding process, which can lead to deformation of the wire, and the wire is not easy to replace after welding.
The advantage of crimp connection is that the connection is reliable and easy to operate; The disadvantage is that there are potential risks such as poor crimping and loosening of the wire.
The advantage of threaded connection is that the connection is stable, easy to disassemble and replace; The disadvantage is that the connection process is cumbersome and requires high operator skills.
The advantage of plugged connection is that the connection is fast and the operation is simple; The disadvantage lies in the potential risks such as poor plugging and easy loosening.
