1766886-4: Backplane Connectors - Contacts

The 1766886-4 backplane connector is a low-profile contact designed to quickly and eas- ily connect two printed circuit boards. This contact is a shielded backplane connector, meaning it has increased contact-spacing isolation that protects sensitive high-density circuitry from electrostatic interference. Its ease of use and its structural strength make it suitable for use in a wide variety of applications.

Application Field

The 1766886-4 backplane connector is ideal for applications requiring low-profile, high contact-density and shielding, such as in telecommunications, data communications, and telecommunications network equipment. Because the connector is designed to connect two printed circuit boards, it is well-suited for applications requiring maximum board-to-board connection density, such as:

• Inner board and backplane interconnections
• Router and switch boards
• Modules for mass storage systems
• PCI Express cards
• Network interface cards
• Motherboards for servers

The 1766886-4 backplane connector can also be used in a variety of industrial applications such as medical imaging, laboratory instrumentation, industrial control boards, and automotive electronics.

Working Principle

The 1766886-4 backplane connector consists of two parts—a contact and a receptacle. The contact contains a series of pins, and the receptacle contains slots that correspond to the pins. The connector is designed to provide a tight fit between the contact and receptacle. It is also designed to allow the pin-to-slot connection to be easily and quickly disengaged.

The connector\'s tight fit is achieved by using a pressure-based locking mechanism. This mechanism is triggered when the contact is inserted into the receptacle, which causes the pins to move and engage more securely with the slots. This locking mechanism helps ensure that electrical conductivity is maintained between the two components while providing a reliable and durable connection.

The 1766886-4 backplane connector also contains built-in shielding and insulation to protect against electrostatic interference. This shielding minimizes the chance of cross-talk, providing a clean signal path between the two connected components.

Conclusion

The 1766886-4 backplane connector is a low-profile contact designed to connect two printed circuit boards. It is well-suited for high-density applications, making it ideal for a variety of applications in telecommunications, data communications, and industrial control. Its pressure-based locking mechanism ensures a tight fit between the contact and receptacle, while its shielding and insulation protects against cross-talk and electrostatic interference.
