Nowadays, copper terminals have been gradually used in the industrial automation production industry. Because copper terminals have a wide variety and complete functions, they have incomparable advantages as wiring accessories in the past. However, how to correctly apply copper terminals to the field of wire connection and signal transmission is a problem that needs to be considered, The most important thing is which connection mode to choose when using copper terminals. Reasonable selection of connection mode can make the use of copper terminals more effective. Today, I'll introduce several connection modes of copper terminals to you
Among them, the most common connection of copper terminals is welding, and tin welding is the most common. The simple point of tin welding is to connect the same terminal surface and tin material to produce metal continuity. Therefore, in the connection mode of welding, the most important thing is the solderability of copper terminals, If the copper terminal is of high quality in weldability, this connection method can be adopted, and the effect is very remarkable
The second connection method of copper terminals is crimping. The so-called crimping is a technology that compresses and positions the copper terminals within the specified requirements, and then connects them. The advantage of crimping is that it dissolves and flows the metal through the technology to obtain better mechanical strength and electrical energy continuity, Crimping connection is generally used in places with poor environment, so that the connection can withstand the influence of some external adverse factors, especially in places with large current, crimping connection is designated as the only connection, and the reliability and stability of crimping is also higher than that of welding, However, the crimping connection has one of the most fatal disadvantages. The crimping connection is a permanent connection and can only be used once, so it is not widely used as welding in use
The third connection mode of copper terminal is winding. Winding mainly uses winding gun and fixed winding machine to directly wind the conductor on the winding column of the contact. Generally, the conductor is wound, pressed and fixed on the contact to form an absolute air tight seal. Of course, the connection mode of winding connection is not as common as the other several connection modes, because it has many requirements and has clear scope provisions on the conductor diameter and the extensibility of conductor materials, which leads to certain specifications and can not be used on a large scale
The fourth connection mode of copper terminal is puncture connection. Puncture connection is a relatively advanced and high-end technology. At present, it is not widely used. It is mainly applicable to the connection between some ribbon cables. The main operation mode is to insert the contact spring of copper terminal into the insulating layer, and then let the conductor of cable clamp the copper terminal, This connection method can make the connecting line between the copper terminal and the cable more compact, the operation is also very simple and convenient, and the operation is also very stable and reliable. Why is it not widely popular? In fact, it is the same reason as winding. It is also limited in connection. Although the tools required for piercing connection are relatively simple, the cable with specified wire gauge must be used
