Contact force is an essential element of terminal blocks. Terminal Block is an accessory product used to realize Electrical Connection, which is divided into the category of connector in industry. Terminal Connector With the increasing degree of industrial automation and the stricter and more precise requirements of industrial control, the amount of terminal connectors has gradually increased. With the development of the electronics industry, the use of terminal blocks is increasing, and there are more and more types. The terminal block is used to facilitate the connection of wires. It is actually a piece of metal sealed in insulating plastic. There are holes at both ends to insert wires, and screws are used for fastening or loosening, such as two wires, sometimes Need to connect, sometimes need to disconnect, then you can use the terminal to connect them, and can be disconnected at any time, without having to solder or twist them together, very convenient and fast. Using a high quality conductive material is of no use if you don't have a good contact force. If the contact force is low, there will be displacement between the wire and the conductive plate, and serious oxidative pollution will occur, causing the contact resistance to increase and overheating. If the wire frame of the terminal block is used, the impact on the environment does not exist, and because of the large contact area and the large force, the connection is more durable. However, if the voltage changes, the impact on the contact force will be relatively large, which mainly depends on the quality of the terminal board. Therefore, if we choose the method of crimping frame for the terminal, in fact, the enterprise is still relatively safe and reliable. After the screw is tightened, the tongue of the thread on the surface of the crimping frame will pop out directly, and it will play a certain role in the screw. The reverse promotion effect, however, because the diameter of the wire has some changes due to the ambient temperature, so the crimping frame itself will not be seriously affected in terms of elasticity. Wire Connection also has a certain persistence in the self-locking function, but it can only play its main significance online. Due to different operators, the torque requirements will be different, so the quality of the connection will not be affected, which can also reflect the quality of the wire rack. importance. In addition, if Terminal Block uses wire frame, there is no need for any maintenance, because air tightness can be used in different environments, such as ordinary air temperature, humidity, and can be used for terminal blocks for a long time, so the terminal blocks also need to have good environmental factors. But even so, the influence on the contact force of the terminal is not very big. Even if the terminal is directly connected to the flexible wire, the pressure wire frame can keep the air tightness very well, which is why the terminal must choose the wire The main factor of the box mode, because its advantages are very obvious.
