Card Edge Connectors - Housings

Card edge connectors are used to join two printed circuit boards (PCBs) to form a larger system, which will enable the flow of data and signals between the two boards. The 582371-9 is one such card edge connector. It has a sitting height of 9mm and a pin count of 50. The connectors are fully shielded for improved electromagnetic performance and the contacts are stamped and formed for reliability. This article will provide information about the 582371-9\'s application field and working principle.

582371-9 Application Fields

The 582371-9 is designed to be incorporated into computer backplanes, high current switching and power supply systems. Its compact design and robust construction make it suitable for applications where space is at a premium and vibration or shock resistance is necessary. It has a reliable, low contact resistance which provides good contact stability and electrical performance over a wide operating temperature range.

The 582371-9 is also designed for military applications where high-density and superior electrical performance are required. It is tested to meet military environmental specifications, and it has cyclic durability of 2500 cycles and withstands shock of 100G and vibration of 5G.

Moreover, its low profile design allows it to be used in applications where height is limited, such as the automotive industry. It is robust and reliable, which is a must in the automotive industry where vibration and shock are common.

582371-9 Working Principle

The 582371-9 card edge connector utilizes two sets of contacts: power contacts and signal contacts. It is designed so that the power contacts are isolated from the signal contacts and are positioned lower than the signal contacts to mitigate electromagnetic interference. The power contacts also have a higher load capability than the signal contacts.

The power contacts consist of two parallel rows of differential pairs of contacts in which the mating pins are of different configurations. The power contacts can support dual current applications, where the current can go up to 12A. The pairs of contacts are also capable of carrying more power than the signal contacts.

The 582371-9 signal contacts consist of two parallel rows of standard contact configurations that support both front- and back-mounting. It has a high-retention force that ensures a reliable connection and provides common-mode choke for improved signal integrity. Its vibration-resistant design enables proper fitting and connection even when exposed to shock and vibration.

The 582371-9 card edge connector is designed for high-power and high reliability application in the military, automotive, and other harsh-environment applications. Its robust construction and reliable performance make it suitable for numerous applications.
