Connectors are essential components in various applications to enable data and power transmission. Rectangular connectors are one of the most common types, featuring two mating parts that accommodate multiple contacts. The STMM-114-02-G-D-SM is a type of compact rectangular connector typically used in a variety of applications. This article will discuss the application field and working principle of the STMM-114-02-G-D-SM.

Application Field

The STMM-114-02-G-D-SM is designed for applications where space is limited, such as within digital automotive, communication, industrial, and consumer electronic devices. It is a small connector that comprises an insulating body that securely holds two parallel rows of two pins on a 0.188” pitch. These two rows have opposing centerline layouts which allow them to mate with other connectors in the STMM series. The small size of the STMM-114-02-G-D-SM makes it ideal for a variety of applications that require low-frequency signal transmission. In addition, the connector has a flexible design that allows it to be easily soldered with high-frequency waves, making it suitable for a wide range of applications.

Working Principle

The STMM-114-02-G-D-SM consists of two primary parts: the header and the male pins. The header is a one-piece insulation casing that includes two parallel rows of two pins. These are spaced 0.188” apart and are designed to mate with the male pins of another connector. The male pins, on the other hand, are individually encapsulated parallelepiped-shaped structures that include two configuration pins. These pins then enter the header of the opposite mating connector, engaging the header pins and creating an electrical connection.

Once the pins enter the header, they are held in place securely by pre-stressing forces within the header. The pre-stressing forces are controlled by the configuration pins, which interact with the configuration holes in the header and allow for a secure connection. The engagement force is also adjustable to suit a variety of applications. When the mated connectors are pulled apart, the engagement force increases, ensuring that the connection is secure.

Conclusion

The STMM-114-02-G-D-SM is a rectangular connector composed of an insulating body and two parallel rows of two pins. It is designed for applications that require low-frequency signal transmission and features a flexible design that allows it to be easily soldered with high-frequency waves. The connector utilizes pre-stressing forces within the header and the configuration pins to ensure a secure connection, making it suitable for a wide range of applications.
