Rectangular connectors are one of the most commonly used connectors in a wide range of applications. The 91900-21225 connector is a product of this family and is used in many different settings. Being a form factor that is designed to fit together on both sides of a circuit board, the 91900-21225 rectangular connector is well-suited for a multitude of uses. In this article, we will go over what applications the 91900-21225 rectangular connector can and cannot be used for, as well as its working principle.

Edge Type Arrays

The 91900-21225 rectangular connector has a variety of applications when used as an edge type array connector. This type of connector is mainly used in situations where there are multiple boards that need to be connected together. The connector is easily connected to the edge of the boards and can come in different sizes to fit the boards that they need to be connected to. There are also versions of this connector which have extra components like grounding tabs for additional support. Additionally, this type of connector is great for when high contact density needs to be achieved and when space is very limited.

Mezzanine (Board to Board)

The 91900-21225 rectangular connector is also used as a board-to-board connector in many applications. This type of connector is a great option when boards must be connected to one another but there is no available space to mount a connector. Additionally, the connector has the capability to self-align with mating connectors on either side of the board. The parts can be mounted directly onto the boards and the connection will be made securely without needing to mount any additional components. It is also possible to use the board-to-board connector in applications where dual-inline connectors are used, as the 91900-21225 connector can provide better performance and reliability.

Working Principle

The working principle of the 91900-21225 rectangular connector involves a few components. First, the connector has a number of spring-loaded contact elements. These contact elements are designed to make an electrical connection between the two components when the connector is mated. Once the contact elements are mated, they connect to the two components by pressing against each other using the spring-loaded component. This makes sure that they are held in place while providing an electrical connection between the two.

The second part of the working principle is the shell or housing of the connector. This is a metal component that is designed to protect the contacts of the connector from damage. It also provides structural integrity and ensures that the connections stay secure. The shell is also usually coated in a protective material to prevent the connector from corroding and degrading over time.

Lastly, the connector also has a grounding pin that is used to provide a secure grounding connection. This is usually connected to the shell of the connector and is used to protect against electrostatic discharge. This is important in high-voltage applications such as computers, as it ensures that any stray electricity is channeled away from the rest of the system.

Conclusion

The 91900-21225 rectangular connector is a versatile connector that can be used in a variety of applications. From edge type arrays to board-to-board connections, this form factor is designed to be compatible with a multitude of uses. Additionally, its working principle involves a number of components that work together to ensure a secure connection and a safe working environment. With its many uses and features, the 91900-21225 rectangular connector is an excellent option for connecting circuit boards in a variety of applications.
