Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board)

Rectangular connectors are a versatile and reliable type of connection solution that is used in almost every industrial, commercial, and residential environment. These connectors are available in a wide variety of shapes and sizes, and can be used to connect wiring, devices, and boards to one another in a variety of ways for various purposes.

A 91920-21141 rectangular connector is an array edge type mezzanine (board to board) that is designed for use in devices that require seamless electrical connectivity. It is a low-cost and small form factor type of connector that is suitable for a variety of applications, such as providing power to portable electronics and computer motherboards.

Application Field

The 91920-21141 connector is ideal for hand-held electronics, single board computers, and I/O boards. It is also suitable for many signal-carrying functions such as parallel input/output (I/O) applications in communication systems and small PCB assemblies. The small form factor of the connector makes it a convenient option for use in tight spaces. Additionally, it is often used in applications where power connectors must form a reliable connection with minimal contact resistance.

Working Principle

The 91920-21141 is designed to provide an array edge type connection. The edges of the board are used to make contact with the connected boards. The contacts are made by inserting two rows of contacts into the mating board edge contacts. This ensures that the contacts are properly aligned and that the connection is secure. The 91920-21141 is designed to provide a reliable connection with minimal contact resistance. This is because the contact resistance is a function of the distance between the contacts. The connector is also designed to reduce the risk of arcing as the current is induced due to the low contact resistance.

To ensure a secure and reliable connection, the contact resistance must be kept as low as possible. This is achieved by using the highest grade of phosphor bronze contacts that have been gold-plated for additional reliability. Additionally, the contacts are designed to self-adjust and form a tighter and more reliable connection as they are plugged in. This is due to the having a “spring” effect on the contacts, which increases the amount of friction between the contact and the mating board. Additionally, the connector is designed with a latching feature that helps to ensure that the connection will stay in place.

The 91920-21141 connector is a reliable and cost-effective type of connector that is suitable for a variety of electronic applications. It is designed to provide a secure and reliable connection with minimal contact resistance, and is suitable for a variety of applications including hand-held electronics, single board computers, and I/O boards. Additionally, it is designed to reduce the risk of arcing and form a tight connection due to its spring effect contacts and latching feature.
