Application Field of TMM-125-01-S-S-SM

TMM-125-01-S-S-SM rectangular socket header is an important series of products of commercial connectors. It is a high-performance, high-integrity, cost-effective connector system with a variety of accessories. It has superior performance in signal transmission, power transmission and so on, and can meet different requirements of various application fields. This type of product is mainly used in industrial control system, multimedia electronics, mobile phone, tablet, LED lighting, digital media and other fields.

Working Principle of the Product

Generally speaking, the TMM-125-01-S-S-SM consists of a copper plated contact, a zinc-plated steel socket, and a nylon or PBT insulator. The plastic material that makes up the connector helps to reduce the weight of the product and guarantee its overall performance.The contact on theTMM-125-01-S-S-SM has a double-sided contact structure, which can ensure a stable connection. Both sides of the contact are pressed into the inner wall of the chamber with a series of simultaneously formed crimps, which can prevent the contact from loosening and improve the overall reliability. When the connector is assembled, the contact can fit into the plastic insulator with a predetermined accuracy, and the last step is to insert the plastic insulator into the metal spring of the socket. At this time the connector assembly is completed.When a mating occurs, the end of the contact will pass through the slot of the mating part into the internal chamber of the metal spring. At this time, the contact will be supported by the spring pressure and electrical contact between them will be established, thus the electrical connection is completed.

Conclusion

In conclusion, rectangular socket headers such as the TMM-125-01-S-S-SM are a common type of connectors used in various fields. This type of product has excellent safety and reliability, excellent electrical performance, and can meet the requirements of applications in various fields. Its contact structure also helps to ensure a more reliable connection.
