Rectangular connectors have been a popular choice in the field of electrical engineering applications for many years. These types of connectors offer the advantages of both convenience and reliability. In this article, we will discuss the 91910-21269 application field and working principle of the rectangular connectors - arrays, edge type, mezzanine (board to board).

Arrays Connectors

Array connectors are typically used in applications requiring a large number of I/O ports and providing secure connections at relatively lower costs. Array connectors are constructed with a method of engagement which allows a large number of contacts to be connected simultaneously with a single locking lever. This design reduces the cost involved in the application and generally requires less assembly time. The common types of array connectors have either 96 or 144 pins which are arranged slightly diagonally in pairs. These array connectors are generally used in applications such as Ethernet connections and printed circuit boards.

Edge Type Connectors

Edge type connectors are another type of rectangular connectors, which are commonly used in applications such as connecting printed circuit boards to one another or connecting printed circuit boards to a backplane. Usually, the termination points are present at the end of the connector as it is designed to fit within the slot of the PCB or the backplane. These types of connectors feature rows of snap-in contact pins which interlock with the housing to ensure stable electrical connections. Edge type connectors are commonly available in three contact patterns - right angle, straight, and reverse. The 91910-21269 connectors feature a right angle contact pattern which is opposed to the straight or reverse type connections.

Mezzanine (Board to Board) Connectors

Mezzanine connectors are commonly used in applications such as motherboard to daughterboard and daughterboard to daughterboard connection. These types of connectors usually feature two or three row right angled contact patterns which reduce contact resistance and help in avoiding hairpin problems. Furthermore, mezzanine connectors also feature a secured latching mechanism to ensure that the assembling steps are done securely and in no time. The 91910-21269 connectors feature two row and three row termination options, which help the end user to opt for the most suitable option according to the application.

Working Principle of 91910-21269 Connectors

The working principle of the 91910-21269 connectors follows the traditional design of rectangular connectors - arrays, edge type, and mezzanine. The main components are an insulator, a contact, and a locking mechanism. The insulating material helps to provide electrical insulation to the contact and prevent short circuiting. The contact has a necessary mechanical locking feature, which is necessary to ensure the contact remains in place during the engagement of connectors. The locking mechanism secures the connection between the contact and the insulator, providing it a strong and reliable connection.

Conclusion

In conclusion, the 91910-21269 rectangular connectors are widely used in applications such as Ethernet connections, printed circuit boards, motherboard to daughterboard, and daughterboard to daughterboard connection. These connectors feature arrays, edge type, and mezzanine contact patterns and a locking mechanism which not only ensures reliable electrical connections but also requires minimal assembly time. The working principle of these connectors is quite straightforward and all the components responsible for providing a secure and reliable connection are available.
