Backplane connectors specialize in connecting circuitry elements of a system board or a daughterboard in a device. 1703403022 are one of the specialized types on backplane connectors. In this article, the application field and working principle of a 1703403022 will be discussed. Application Field1703403022, also known as HSBP (Half Size Basic Backplane) is a specialty backplane connector that is a horizontally mounted, high-density bus interface. It has been designed to connect circuitry elements on a system board or in a daughterboard. With its distinctive pin-based layout, it utilizes square-pin connections and compliant pin contacts to ensure high-reliability and safe connections.The 1703403022 was original designed for use in a variety of consumer electronics and telecommunications systems such as computers, notebook and tablet computers, server systems, GPS receivers, and mobile phones. In recent years, as the speed and reliability of consumer electronics and telecommunications systems have increased, so has the demand for 1703403022 backplane connectors. They are now commonly used in a wider range of applications, such as in user interface boards, system-management circuit boards, and video image processing boards.Working PrincipleThe 1703403022 backplane connector is designed to allow a number of high-speed signals to be passed between different device subsystems or daughterboards. Its distinctive pin-based layout allows it to provide higher density than other backplane connectors. It utilizes an array of square pins that fit tightly into a slot at the contact edge, and compliant pin contacts spring in to connect with the signal lines. This ensures reliable, consistent and secure connections for transferring data signals.The pins of the 1703403022 are arranged in two symmetrical rows to ensure reliable connections between the daughterboards and the backplane. The contact edge is fitted with a seal to protect the connector from moisture and dust, and the pins are coated with a special resin material to provide resistance to corrosion.The 1703403022 also includes a unique feature that allows for redundancy in the connections. It has two redundant contacts at the ends of each row of pins, which can be used in case one connection fails. This ensures continuous signal transmission even when a single connection fails.In summary, the 1703403022 is a specialized, high-density backplane connector that serves a variety of applications in consumer electronics, telecommunications, and industrial systems. It can provide reliable, secure connections for transferring data signals and has unique features that allow for redundancy and resilience.
