TFM-149-01-H-D-RA Application Field and Working Principle

The TFM-149-01-H-D-RA is a type of rectangular connector, specifically a header male pin. It’s a component used to link circuits, and typically used when a low-temperature solder is required. The connector features a resistance welding connection and takes a 1.27 mm spacing between terminals.

Application Field

The low-temperature solder of the TFM-149-01-H-D-RA is suitable for electronic equipment, microwave ovens, wireless communications and other applications in which low temperatures create a challenge. The connectors are typically used with or without female receptacles, and often feature a push-in latching system for improved connection stability.

Working Principle

When the male and female terminals of the TFM-149-01-H-D-RA are mated, they create a secure mechanical and electrical connection. This is due to the ridges, or barbs, that are present on the metallic portions of the connectors. The ridges create an interference fit within the plastic connectors, providing a tight grip on the receptacle. This grip ensures that the male and female connectors remain firmly attached when in use.The other major component of the TFM-149-01-H-D-RA connector is the resistance welding mechanism. By electrical induction, the male and female terminals are able to bond, providing an extra layer of connection security and reliability. This is invaluable in high-vibration applications, where other connector types may seperate due to movement.

Additional Uses

The low temperature of the TFM-149-01-H-D-RA connector also enables the use of thermal paste in certain applications. The paste is an effective way of managing heat in locations where it may need to be regulated, such as in high-speed processors.The latching mechanism of the connector also eliminates the need for soldering in certain applications. This makes the connector well-suited for fiddly work, such as board-to-board design, where soldering is not always the most practical solution.

Conclusion

The TFM-149-01-H-D-RA is a versatile and reliable rectangular connector, ideal for low-temperature applications. Its ridges, or barbs, provide a secure mechanical connection, while the resistance welding ensures a strong electrical bond between the male and female pins. Additionally, the low temperature enables the use of thermal paste in certain applications. The latching system also enables applications where soldering is not viable.
