Introduction of UK terminal

Promulgator : DIHAO Date : 2018-07-10

The UK DIN Rail Terminal Blocks are used to facilitate the connection of the wire. It is actually a piece of metal sealed in the insulating plastic. Both ends have holes to insert the wire. There are screws for fastening or loosening. For example, two wires, sometimes needed to connect, and sometimes need to be disconnected, can be connected to them with terminals. And they can be disconnected at any time without having to weld them or wrap them together, which is very convenient and quick. A certain crimping area is designed to ensure reliable contact and ensure enough power. The metal conductor inside the terminal is the core part of the terminal, which transfers the voltage, current, or signal from the external wires or cables to the contacts corresponding to the connectors that they match. Therefore, contacts must have excellent structure, stable and reliable contact force and good electrical conductivity.

Interchangeability examination is a dynamic check. It requires that the same series of Industrial Plugs And Sockets can be intercalated with each other. It is found that there is no intercalation, positioning and locking, or even disintegration under the use of rotating force, because of the oversize of the insulators, contact parts and other parts, and the lack of parts or assembly. Another function of interchangeability inspection is to find out whether there are metal remnant that affects insulation performance in time. Therefore, some important UK terminals should be checked by 100% to avoid such fatal accidents. The single hole separation force refers to the separation force from the static state into the moving contact, which is used to characterize the contact between the pin and the socket. The experiment shows that when the single hole separation force is too small, it may cause signal break when subjected to vibration and impact load. It is effective to check contact reliability by measuring single hole separation force than measuring contact resistance. It is found that the contact resistance of the jack with a single hole separation force is still qualified. Therefore, in addition to developing a new generation of flexible intercalation contact and stable contact parts, the production plant should not use the multi point test of the automatic pulling force test machine for the key model, so that 100% of the point by point single hole separation force check for the finished product should be carried out to prevent the signal transient caused by the relaxation of the individual Jack.

Disintegration refers to the abnormal separation between the plug and socket caused by the unreliable structure of the Industrial Plugs And Sockets caused by the unreliable structure of the UK DIN Rail Terminal Blocks in the intercalation state, which will result in the serious consequences of the power transmission of the control system and the interruption of the signal control. Due to unreliable design, wrong selection of material, improper selection of molding process, poor quality of heat treatment, die, assembly and welding, and so on. Without reliable DIN Rail Terminal Blocks, there is no reliable system engineering. Failure and reliability are two aspects of a contradictory body that corresponds to each other. Through the reliability screening of terminal terminals, various failure modes and failure mechanisms can be found, which can lead to a large number of experience and lessons and eliminate all kinds of hidden dangers. It provides a scientific basis for improving design, process, inspection and use. It is also an important basis for revising and formulating the technical conditions of terminal terminals. It is the ultimate goal of failure analysis to find ways to prevent failures and transform them from failure to reliable ones.
