Introduction

Rectangular connectors are used in a variety of electronic applications to form a connection between two devices or components. The connectors are available in different shapes and sizes, depending on the specific application for which they are intended. The SSQ-112-21-L-D is one type of rectangular connector that can be used for a range of applications. In this article, we will look at the application field and working principle of the SSQ-112-21-L-D rectangular connector.

Application Field

The SSQ-112-21-L-D is a high-performance rectangular connector. It is specifically designed for industrial and military applications that require an efficient and reliable data transfer system. Due to its robust construction, this particular connector can be used in applications that require high temperatures, such as ship cockpit automation systems, navigation systems, and auto-pilot systems. It is also often used in aerospace, railway, and heavy-duty applications for data transmission and power supply.

Design and Components

The SSQ-112-21-L-D rectangular connector is composed of two parts: the header and the receptacle. The header, which is the male part, contains a number of pins (typically 21) that connect to the receptacle, the female part. The pins of the header electrically contact the spring loaded contacts present in the receptacle.

Working Principle

The working principle of the SSQ-112-21-L-D rectangular connector is based on the spring loaded contacts present in the receptacle. When the header with the pins is inserted into the receptacle, the contacts in the receptacle compress and make electrical contact with the pins of the header. This contact creates an efficient electrical connection between the two components. The construction of the connector makes it resistant to shock and vibration, ensuring a reliable connection.

Conclusion

The SSQ-112-21-L-D is a high performance rectangular connector that is specifically designed for industrial and military applications. It is composed of two parts—the header and the receptacle—that when combined together create an efficient electrical connection via the spring loaded contacts present in the receptacle. This connector provides shock and vibration resistance and is suitable for a variety of applications.
