Industrial connectors, we also call them connectors and plugs. Its function is to connect two active components and act as a current and signal transmission function. The more famous connector brands include Yuanya, Toshiba, and Kanami. Depending on the application object and environment, the connector is divided into several models, but no matter what kind of FPC connector, it must ensure smooth and reliable transmission of electrical signals. With the changes in the application environment, connectors have derived many connection methods, the purpose is to better adapt to the on-site environment and ensure stable signal transmission. Here are some common connector connection methods.
1. Threaded connection
This is a traditional connection method, which is relatively rare now. It will be useful in some larger components or environments with strong vibration. The advantage of this connection form is that it is highly reliable and the cable is fixed by the friction of the nut gear. If a fuse is added to prevent loosening, the effect will be better. The disadvantage is that the disassembly speed is relatively slow, and it takes a little electricity to withdraw the thread, which is very time-consuming.
2. Bayonet connection
This is a popular connection form that can be quickly connected and separated. Commonly used to connect two simple electrical components, the connector with snap-on connection will mark the correct snap-on locking direction at the snap-on. The user can observe whether the snap-on is installed through the small hole on the side of the connector nut.
3. Plug-in connection
Plug-in connection is a commonly used connection method. The plug and socket of the connector can be connected and separated by moving horizontally. It does not require twisting and optional installation. It can be connected and separated in a very short time. Common plug-in connections have two structures: ball bearings and pins. This connection method eliminates the traditional mechanical locking mechanism, so once the connector is plugged in by mistake, it is very difficult to pull it out.
4. Cabinet connection
It is an electrical connection method based on the need for blind connection to the equipment close to the frame. This method can make the electrical equipment very light and small, and each unit works independently of each other, which is easier to maintain and more reliable. Since the operator cannot perceive the connection status in this connection method, a precise positioning device must be used to assist the smooth connection. Floating contact or spring design is usually used to ensure its correct connection.
5. Soldering connection
Soldering connection means that continuous metal should be formed between the solder material and the surface to be welded. Therefore, the prerequisite for the connector is that it must be weldable. Common plating layers on the connector welding end include metals such as tin alloy, silver and gold. Common welding ends for reed-type contacts include soldering plates, punched soldering plates and notched soldering plates: common welding ends for pinhole contacts have drilled arc notches.
6. Piercing connection
Piercing connection, also known as insulation displacement connection, has the characteristics of high reliability, low cost and ease of use. It has been widely used in connectors in the printing industry. It is suitable for interconnection between ribbon cables. When connecting, there is no need to pierce the insulation layer of the cable. With the help of the tip of the "U"-shaped contact reed of the connector, the conductor of the cable slides into the concave groove of the connector and is fixed, so that the cable and the connector are in close contact.
