Card edge connectors are contacts, or fittings, that allow electrical connection between a printed circuit board (PCB) and a card such as a daughter card or extended card. There are several types of card edge connectors. One such type of card edge connector is the 66084-3, which accomplishes connection between a PCB and card by means of pushing the card edge into the connector. This article will discuss the application field and working principle of the 66084-3 card edge connector.

Application Field

The 66084-3 card edge connector is an ideal solution for connecting daughter or extended cards to a PCB. It is specifically designed to fit snugly into slots in cards, so that it stays securely in place. The 66084-3 connector also has a low profile and does not protrude much from the surface of the card. This makes it well suited for applications that require small and compact designs. Since the 66084-3 connector is able to provide high levels of mechanical retention, it is well-suited for use in harsh environments and vibration-prone applications, such as automotive, consumer electronics, instrumentation and test equipment.

Working Principle

The 66084-3 card edge connector is a contact-based connector, which makes electrical connection between a PCB and card by means of pushing the card edge into the connector. This type of connection is made possible by the use of spring action contacts, which are spring-loaded contact pads on the PCB. When the card is inserted into the connector, the contacts on the card push up against the corresponding contacts on the connector. This electrical connection is maintained as long as the card remains in contact with the connector. The 66084-3 connector also features a keying system, which allows the connector to be rotated into the card or PCB in only one orientation. This helps to ensure that the card and connector are electrically connected in the correct orientation.

Furthermore, the 66084-3 card edge connector is designed to accommodate a range of card thicknesses. This makes it suitable for use with a variety of different applications. The connector can also be easily customized with different contact configurations to accommodate different types of connection requirements.

In summary, the 66084-3 card edge connector is an ideal solution for connecting a daughter or extended card to a PCB. It is made with spring-action contacts that are spring-loaded on the PCB, and it has a keying system that allows the connector to be rotated into the card or PCB in only one orientation. Additionally, it has a low profile and can accommodate a variety of card thicknesses. All of these features make this connector well-suited for use in a variety of harsh environments and vibration prone applications.
