Contact force is an essential element of terminal blocks. Terminal Block is an accessory product used to realize Electrical Connection, which is industrially divided into the category of Terminal Connector. Terminals With the increasing degree of industrial automation and stricter and more precise industrial control requirements, the amount of terminal blocks is gradually increasing. 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 for inserting wires, and there are screws for fastening or loosening. For example, two wires, sometimes If they need to be connected, sometimes they need to be disconnected. At this time, they can be connected with terminals, and they can be disconnected at any time without having to weld them or twist them together, which is very convenient and quick. It is useless to use high quality conductive material without good contact force. If the contact force is low, displacement will occur between the wire and the conductive plate, and serious oxidation pollution will occur, resulting in continuous increase in contact resistance and overheating. If the wire frame of the Wire Connection platform is used, the impact on the environment does not exist, and because the contact area is large and the force is large, the connection is relatively durable. However, if the voltage changes, the impact on the contact force will be relatively large, mainly depending on the quality of the terminal board. Therefore, if we choose the crimping frame for the terminal block, the company is actually relatively safe and reliable. After the screw is tightened, the threaded tongue on the surface of the crimping frame will pop out directly, and have a certain effect on the screw. Reverse promotion, however, due to some changes in the diameter of the wire due to the ambient temperature, the elasticity of the crimping frame itself will not be seriously affected. The self-locking function of the terminal block also has a certain durability, but it can only play a major role on the line. Because the operator is different, the torque requirement will be different, so the quality of the connection will not be affected, which can also reflect the quality of the line frame. importance. In addition, if the terminal block uses a wire frame, there is no need for any maintenance, because the airtightness can be used in different environments, such as ordinary air temperature, humidity, and the terminal block can be used for a long time, so the terminal block also needs to have a good environmental factors. But even so, the impact on the contact force of the Terminal Block is not very great. Even if the terminal block is directly connected to the flexible wire, the pressure wire frame can maintain a good airtight performance, which is why the terminal block must choose wire The main factor of the box mode, because its advantages are very obvious.
