Rectangular connectors—headers, male pins—have been used for decades in wide-ranging applications, such as automotive, consumer electronics, and more. In this article, we’ll dive into the application field and working principle of the TMMH-137-04-S-5 type connector.

What is a TMMH-137-04-S-5 type connector?

TMMH-137-04-S-5 connectors are rectangular, molded plastic housing with metal oxide contacts and pins positioned parallel to one another. It has five pins—four receptacles and one pin—in a L-shape form, arranged 3-2. This type of connector is commonly used in automotive applications.

Application Field

TMMH-137-04-S-5 connectors are made to withstand extreme temperatures and have a wide range of applications. They are commonly used in automotive, consumer electronics, and related industries.

In automotive applications, TMMH-137-04-S-5 connectors are used in vehicles such as cars, vans, trucks, and more to provide power and data transfer for peripherals such as sensors, GPS navigations, infotainment systems, automatic control systems, and more.

In consumer electronics, TMMH-137-04-S-5 connectors are used in household appliances such as television sets, washing machines, microwave ovens, air conditioners, refrigerators, and more to provide power and data transfer for peripherals such as sensors, displays, and keypads.

Working Principle

TMMH-137-04-S-5 connectors employ compact design, high reliability and corrosion resistance to meet the needs of their various applications. They use a mechanical lock-ring style to ensure a secure and vibration-resistant connection.

The TMMH-137-04-S-5 connector has four terminal receptacles, and they’re symmetrically arranged on the two sides of the connector. Each receptacle is contacting with the spring-loaded male terminals in the header, and the pins have a positive lock that prevents accidental loosening of the connectors. The contacts also feature flattened ends which are in contact with the pins in the header, forming the electrical connection.

The TMMH-137-04-S-5 connector also has anti-twist mechanism, so that two connectors cannot be twisted together, making the working mechanism more reliable. The PVC-housing is flame-retardant quality grade V0, and it ensures the connectors\' connections are stable and durable.

Conclusion

TMMH-137-04-S-5 connectors are widely used in automotive, consumer electronics, and related industries for power and data transmission applications. This type of connector features a molded plastic housing with metal oxide contacts and pins in L-shape form, and they are secured with mechanical lock rings to provide a secure and vibration-resistant connection.
