Rectangular Connectors – Arrays, Edge Type, Mezzanine (Board to Board) connectors are becoming increasingly important in a variety of applications due to their versatility and reliability. The DF9L-31P-1V(21) is a specialized rectangular connector used in many applications and its design and features make it a popular choice. This article will discuss the application field and working principle of this connector, as well as its advantages.The DF9L-31P-1V(21) is a high-speed rectangular connector used in a variety of applications. It is designed for signal, power, and/or hybrid applications and can be used in a variety of technologies, including communication, mobile, consumer, and medical. Due to its versatility, it is highly popular in these sectors. The design of the connector consists of an edge-board receptacle and a mezzanine board connector. The edge connector is a 2-row connector, while the mezzanine connector is a 31-position 0.5mm pitch connector. The mezzanine board connector is the main part of the connector, and it features a variety of features such as insulation displacement contacts (IDC), an integrated shield (ISM), and an integrated locking mechanism that prevents accidental disconnection. The edge-board receptacle is designed to be robust and durable and features a low-profile design. This makes the connector ideal for use in space-restricted areas. The design also allows for a high-speed signal transmission rate of up to 40Gb/s.The working principle of the DF9L-31P-1V(21) is based on the use of insulation displacement contacts (IDC). The IDC is a special contact system that is used to establish an electrical connection between the circuit board and the connector. The IDC contact is usually made of metal and has a protrusion on one side. When the two circuit boards are connected, the contact is pushed against the surface of the circuit board, which displaces the insulation and creates an electrical connection. This results in a secure and reliable electrical connection.The DF9L-31P-1V(21) is a versatile and reliable connector that is suitable for a variety of applications. It features a high-speed signal transmission rate, robust design, low-profile design, insulation displacement contacts, and an integrated shieldand locking mechanism. All these features make the connector an ideal choice for a wide range of technologies and applications.
