Rectangular Connectors are among the most widely used electrical connectors for providing electrical connection and power distribution in electronic systems and electrical equipment. Among the different types of rectangular connectors, the SBH31-NBPB-D21-SM-BK is arguably the most popular one due to its reliable performance and wide application range. This article will discuss its application field and working principle.

Application Field

The SBH31-NBPB-D21-SM-BK is designed for board-to-board connection applications. It is commonly used in communication equipments, servers, computer motherboards, and similar applications. It features a shrouded header construction, making it ideal for use in high-density applications with tight board spacing. It also features a two-row, 31-position, low-profile configuration, and header height of 8.4mm. Its narrow pitch improves design flexibility and increases board-space efficiency, and its SMT terminal design ensures reliable connections.

Working Principle

The working principle of the SBH31-NBPB-D21-SM-BK is straightforward. It is a two-row, 31-position, low-profile header connector that uses a shrouded, board-mountable design to connect two signal boards through the mating of the male pins and female sockets. Electrical connection is formed when the pins from one board are pushed into the sockets on the second board. The shroud at the top of the connector prevents the mating of incompatible components and ensures that there is no accidental contact between them. It also helps indicate which direction the connector should be inserted. The connector is then secured in place by using an adjustable screw or clamp, depending on the application requirements.

Conclusion

The SBH31-NBPB-D21-SM-BK is a popular rectangular connector that is designed for board-to-board connection applications. Its low-profile configuration and SMT terminal design make it ideal for use in high-density applications with tight board spacing and ensures reliable electrical connection. Its working principle is straightforward and reliable, and it is secured in place using an adjustable screw or clamp.
