Backplane Connectors - Specialized 73644-1017 Application Field and Working Principle

Backplane connectors are typically a specialized form of computer interconnects used to support applications requiring connections between printed circuit boards mounted perpendicularly to each other. The specialized 73644-1017 backplane connector is a type of backplane connector designed for high-density applications in a board-to-board configuration. It is a high performance, 24-position connector rated up to 5A per contact, making it capable of handling power and signal requirements simultaneously. The 73644-1017 backplane connector offers a large number of features, including:

• A 26 mm profile that easily accommodates a range of PCB stackups
• High current-carrying capacity of 5A per contact when used with the appropriate mating hardware
• A co-axial contact system for improved EMI protection
• Integrated housings and contacts to reduce cost and ensure repeatable assemblies
• An extensive range of accessory options that allow the creation of versatile and low-cost solutions

The 73644-1017 backplane connector is ideal for applications requiring high-density connections between boards. The housing of the connector is made of a polyester/fiberglass blend and it is sized to fit most PCB stackups. The contacts are gold-plated, providing a reliable electrical connection. The contacts are also co-axial, providing an additional layer of protection from electromagnetic interference (EMI) from external sources.The working principle of the 73644-1017 backplane connector is similar to that of other backplane connectors. The connectors are designed to interconnect boards in a perpendicular orientation, with the contact being forced together as a result of the boards being pushed together. The contact is then moved deeply into its receptacle, making the connection between two boards. This connection is constantly monitored, and if any poor electrical contact is detected, it is corrected by mechanical pressure automatically.The 73644-1017 connectors are also designed to be versatile and low cost. The extensive range of accessories available for the connector make it possible to customize the connection between the boards. This allows for a complete range of options from simple power connections, data transmission or a wide array of other specialized functions. Additionally, the integrated housings and contacts allow for reduced assembly costs. The 73644-1017 backplane connector is a reliable, high-performance, low-cost special connector designed to meet the requirements of high-density applications. This connector provides a reliable connection between two boards, suitable for simultaneous power and signal transmission. The housing is designed for easy installation and the accessories make it easy to customize the connection. The integrated housing and contacts also reduce assembly costs. It is the perfect solution for applications requiring high-density connections.
