Introduction

DF3-7P-2H(20) Connectors (herein referred to as “the Connectors”) are a type of rectangular connectors built with headers and male pins and are designed to simplify connection between circuit boards in electrical equipment. This type of Connectors allows for reliable and stable communication between the connected circuits, reducing assembly time, cost, and size with a high-density connection.

Functionality

The most common use for the Connectors is to provide an electrical signal or power between a board-to-board connection. The housing of the Connector contains multiple contacts, which are held together by an enclosure. The Connectors are easily mounted on a panel or flex cable, and equipped with a contact retention force that ensures secure, reliable engagement. The Connector consists of two parts, a male part and a female part. The male part contains seven pins which insert into the female part of the Connector, which contains seven or eight contacts. The Connectors are typically rated to withstand up to 2 amps per Contact.

Design

The Connectors are designed to provide a secure, reliable connection between two circuit boards or components. They contain either seven or eight contacts which engage one another when the male insert is applied. The contacts are located in the female portion of the Connector, and are designed to provide a tight fit, ensuring a signal or power path between the two connected components. The male pins are designed to be firmly retained within the female port, and are covered with a plastic retainer cap to secure the male pins in place.

Applications

The Connectors are commonly used in a wide range of applications including PCB connections, cable connections, sensor connections, and general electronic device connections. These versatile Connectors are widely used in industrial equipment, consumer electronics, and automotive applications. They are typically available in a range of sizes, including DF3-7P-2H (20). Their small size makes them suitable for applications where space is limited.

Working Principle

When the male pins of the Connectors are inserted into the female contacts, electrical signals or power is transmitted along the path formed. The secure and reliable connection is formed by the contact retention force which is provided by the contacts in the female part of the Connector. This ensures reliable signal or power circulation, minimizing the risk of disruption or slip in connections. Additionally, the Connectors use the self-locking feature to prevent the male pins from forcibly removing from the female port.

Conclusion

DF3-7P-2H (20) Connectors are a versatile and reliable type of rectangular Connectors that are suitable for board-to-board connection, sensor connections, cable connections, and a wide range of electronic device connections. Their secure, reliable connection and their small size make them an ideal choice for applications where space is limited. They consist of two parts, a male part and a female part, and use contact retention force to ensure a stable connection.
