TMMH-143-01-L-DV-EC

Rectangular Connectors - Headers, Male Pins

TMMH Series is a kind of rectangle connectors, which primarily used as a male header with standard mounting and solder pins. The series of TMMH-143-01-L-DV-EC includes mini-bench terminals, D-sub connnectors and other components. Below we will discuss the application field and working principle of this series.

Application Fields

TMMH series is widely used in telecom, cellular phones, handheld transceivers, medical and industrial electronics and industrial control. It is also suitable as an extra choice for application areas in which a combination of low profile, mated height and low cost is required. Moreover, TMMH series has high impedance and offers a maximum of 1,500 V dielectric withstanding voltage.

Working Principle

The working principle of TMMH series is quite simple. The connectors consist of two components, the pin header and receptacle. The pin header is the male component, which contains inset pins or wires soldered to the PCB. The receptacle is the female component, which contains rows of holes with contacts. The male and female components of the connector mate together to form a connection. The pins make contact with the receptacle contacts, forming an electrical connection between the two components.

The contact system of the TMMH series has a unique design that guarantees a reliable connection. The pins are designed with a special plating that improves the contact surfaces and prevents oxidation. This ensures that the contact surfaces remain clean and provides a good electrical contact even after long periods of use. The contacts also have a slip or tear feature that prevents the contacts from sliding out of the connector even when the connector is pulled or twisted.

In addition, each contact has two wire wrap surfaces that provide enhanced mechanical and thermal stability. The standard wire wrap feature also eliminates the need for additional assembly time, as it securely injects the wires into the connector. The TMMH series is also designed for easy installation uses, including push-in, latch, and screw connections. This makes the connectors more versatile and easy to install.

To ensure a reliable connection, the TMMH series also has a locking mechanism that prevents the connectors from accidental disconnections during use. The locking mechanism is designed to provide secure connections and is available in both the male and female components of the connector.

Conclusion

In summary, TMMH-143-01-L-DV-EC series is a type of rectangle connector with low profile, mated height and low cost feature. It is widely used in telecom, cellular phones, handheld transceivers, medical and industrial electronics applications. The device offers a maximum of 1,500 V dielectric withstanding voltage and has a unique contact system that offers reliable connections. In addition, the locking mechanism prevents accidental disconnection during use.
