Various Connection Methods Of Insulated Copper Terminals
Nowadays, copper terminals have been gradually used in the field of automation technology manufacturing. Because copper terminals have a wide range of types and perfect functions, they have many advantages that are incomparable in the entire process as wiring accessories. However, how to correctly apply copper terminals to the field of wire connection and signal transmission is a problem that must be considered smoothly. In such a situation, the key is to choose which connection method in the process of using copper terminals. Reasonable and effective selection of connection methods can make the use of copper terminals more effective. Today I will introduce several connection methods of copper terminals to you.
In such a situation, the most common method of copper terminals in the process of connection is spot welding. In such a situation, tin soldering is the most common. Tin soldering is to connect the outermost layer of the same terminal with the tin material to produce metal continuity. In this way, the key point in the connection method of spot welding is the weldability of the copper terminal. If the copper terminal is excellent in weldability, it can be completely connected by spot welding, and the effect is very significant.
The second connection method of Cable Lugs is crimping. The so-called crimping is a technology that compresses and positions the copper terminal within the specified requirements and then connects it. Some of the advantages of crimping are that the metal is dissolved and flowed through the technology to obtain better mechanical strength and electrical continuity. Crimping is generally used in places with relatively harsh environments, so that the connection can withstand the relevant influence of some external harsh factors. In particular, in some places with relatively large currents, crimping is designated as the ** connection method. The reliable and stable performance of crimping is also higher than spot welding, but crimping has some fatal disadvantages. Crimping is a permanent connection method that can only be used once, so it is not as widely used as spot welding in this regard.
The third connection method of copper terminals is winding. The key to winding is to use a winding gun and a fixed winding machine to directly wind the wire on the contact winding column. Generally, the wire is wound, pressed in, and fixed on the contact at the same time to form an absolute airtight and tight closure. Of course, the connection method of winding is not as common as the other connection methods. The main reason is that the connection method of winding has more specific requirements. There are clear range regulations for the wire diameter and the elongation of the conductor material. This leads to certain specific requirements and specifications for winding, and it cannot be used on a large scale.
The fourth connection method of copper terminals is puncture connection. Puncture connection is a relatively advanced and high-end technology. The actual scope of the second type of use is not yet relatively wide. It is mainly suitable for the connection between some ribbon cables. The key operation method is to insert the contact spring of the copper terminal into the insulation layer, and then let the conductor of the cable clamp the copper terminal. This connection method can make the connection between the copper terminal and the cable more compact, and the operation is also very simple and convenient. After the operation, it is also very stable and reliable. Why is it not very popular? In fact, it is basically the same as winding. It is similar to the connection method in that it is limited to a certain extent. Although the tools required for the puncture connection method are relatively simple and convenient, cables with specified wire gauges must be used when using it.
