Card Edge Connectors - Accessories

Card edge connectors are a type of electrical connector used for providing external connection to electronic cards or printed circuit boards (PCBs). The connector is commonly used in a variety of electronic devices including low-level prototype builds, gaming consoles, power supplies, and even complex robotics projects. The most common card edge connector is the 340-240-318 (commonly referred to as the “3/4 inch card edge connector”). This article will discuss the application fields and working principle of the 340-240-318 card edge connector.

Application Field

The 340-240-318 card edge connector is one of the most common and popular card edge connectors, due to its ability to provide multiple contact positions and its relatively low cost and high reliability. The 340-240-318 card edge connector is widely used across a variety of industries, including the automotive, medical, industrial, consumer electronics, computer/IT, and aerospace. It is commonly used for high speed data transmission, power delivery, and signal integration applications.

Working Principle

The 340-240-318 card edge connector consists of three parts: the base, the contacts, and the cover. The base is typically made of a die cast metal and is designed to protect and secure the card within the connector. The contacts normally consist of metal blades or pins that are soldered to the card edges and are used to transmit signals or power. The cover is used to protect the contacts and prevent any dust or dirt from entering into the connector. When an electrical card is inserted into the 340-240-318 card edge connector, the contacts are forced to move inward and make contact with the electrical card, forming an electrical connection.

Conclusion

The 340-240-318 card edge connector is one of the most commonly used connectors, due to its relatively low cost and high level of reliability. It is widely used across multiple industries, for applications such as high-speed data transmission, power delivery, and signal integration. The connector consists of three parts: the base, the contacts, and the cover. When an electrical card is inserted into the 340-240-318 card edge connector, the contacts make contact with the card and form an electrical connection.
