Card edge connectors, also known as edge connectors, are electrical connectors used to connect computer components to printed circuit boards. Amongst them, the AAC43FSLD is particularly significant, and is one of the most widely used card edge connectors due to its flexible configuration, space-saving form factor, and robust construction. This article will provide an overview of the application field and working principle of the AAC43 FSLD.

Application Field

The AAC43FSLD is a type of edge connector most commonly used to connect a plug to a printed circuit board (PCB). The application field of this card edge connector is fairly wide. It is mainly used in computers, home appliances, office automation, communication, consumer electronics, and general industrial applications.

The robust construction of the AAC43FSLD allows it to perform reliably under wide temperature ranges, and it is ideal for applications with high vibration and shock, such as aerospace and defence applications. Furthermore, the AAC43FSLD is fully compatible with various signal types and protocols, such as Ethernet, USB, HDMI, Fibre Channel, PCI Express, and others.

Working Principle

The working principle of an AAC43FSLD card edge connector is simple and intuitive. The plug is inserted into the connector, which establishes an electrical connection between the plug and the PCB. To ensure that the connection is correctly established, the parts must be used in combination with a contact retainer. The contact retainer is designed to secure the plug in place, as well as ensure a reliable electrical connection.

The reliable electrical connection between the plug and the PCB is facilitated by the AAC43FSLD’s high density of contacts. The contact density of an AAC43FSLD is typically 200 or 300 contacts per linear inch. This makes it possible to route high-speed signals, up to 20 Gbps, through the connector without experiencing signal loss or crosstalk.

Conclusion

The AAC43FSLD is a widely used card edge connector, owing to its robust construction, wide temperature range, and its ability to route high-speed signals. It can be used in applications ranging from consumer electronics to aerospace and defence, and is renowned for its high contact density and reliable electrical connection. Understanding its application field and working principle is important for effective use of this type of card edge connector.
