Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board)

The DF37B-16DS-0.4V(75) connector is part of the rectangular connector category, categorized under Arrays, Edge Type, Mezzanine (Board to Board). It is designed for applications where denser connector packing, higher power-density and greater durability and reliability are required. It is a two-part system that includes a male part, to be mounted on the circuit board, and a female part for connection to the device. The system also includes several other components such as insulator pins, retaining clips, ground contacts, contact pins, and lead frames.

Features of the DF37B-16DS-0.4V(75)

• Polarized
• For Printed Circuit Board Assembly
• Small body size and narrow pitch
• Number of contacts: 16
• High temperature/moisture resistance

Application Field

The DF37B-16DS-0.4V(75) is mostly used in automotive, industrial, and telecom applications. It offers high temperature/moisture resistance and is suitable for soldering and cable harnessing direct to the connector, making it suitable for many applications, including automotive, medical, and industrial applications. In addition, its small size and narrow pitch allow for higher packing density, enabling enhanced control and communication capabilities.

Working Principle

The DF37B-16DS-0.4V(75) includes two parts, a male part and a female part, both of which must be correctly aligned and installed in order for the connector to work properly. The male part consists of a base plate, contact pins, and a contact array. The base plates are adapted for soldering to the printed circuit board; the contact pins serve as electrical contact points; and the contact array captures the system\'s contact force, which ensures secure yet reliable contact. The female part consists of a set of contact pins, an insulation part, and cutouts for the insulation pins.

Each contact pin has a connector tab that slides into the base plate\'s groove, aligning the contact pin with the contact array and establishing electrical connectivity. In order to ensure secure contact, contact pins must also be locked into place with the help of a retaining clip. After contact is established, the connector is insulated with the insulation pins. This prevents electrical leakage in the system and sustains the system\'s contact force.
