CHASSIS CONNECTORS


A new line of PCI riser cage fasteners is enhancing the shock resistance of next-generation server chassis models


F


astener manufacturer Southco has expanded its line of DZUS quick access fasteners with a new product designed specifi cally for PCI riser


cages. In addition to quick access, the fastener assembly provides enhanced shock resistance when connected to next- generation server chassis models. As Global Product Manager Nick


Bennett explains, “T e DZUS D9 Tech Line Quick Access PCI Riser Cage Fastener Assembly off ers simple operation and is designed to secure PCI graphics, audio and storage cards. T e newest addition to Southco’s DZUS Fastener series locks into position quickly and can be easily unfastened to save service time.”


UNDERBODY SERVICE PANELS Southco has a long-standing relationship with the automotive industry as a supplier of innovative fastening products designed to meet the demands of the latest technologies deployed on a wide variety of vehicles. T e company’s DZUS Quick Access


fastener series and captive screws are designed for underbody and under hood service panels that require a high strength and easy-to-remove fastening solution. As a result, the DZUS range is engineered to provide accurate, secure engagement and convenient mounting within an array of applications.


ENHANCED SHOCK AND VIBRATION RESISTANCE T e DZUS D9 Tech Line Quick Access PCI Riser Cage Fastener Assembly accommodates size 2U servers, designed to support the new type of connecter currently deployed by leading server manufacturers. Featuring a captive spring-loaded design and tool-free operation, the fastener assembly locks fi rmly into position to provide shock and vibration resistance. T is durable design ensures the safety of PCI cards if the server is moved or dropped. For installation, the user simply pushes


down on the cap while rotating 180 degrees to fasten the server cage to the mating receptacles on the chassis. Meanwhile, the


D9 PCI Riser used in Data Centre Storage Solutions


set clamping force provided by the fastener prevents over-tightening. To ensure compatibility with a variety of PCB thickness ranges, the DZUS D9 Tech Line is available with multiple stud lengths which make it easy to install, remove and replace server cards. T e fastener assembly combines Southco’s quarter-turn and captive fastening technologies to provide consistent and reliable clamping force, as well as quick access. Essentially, the quick access fastener is


engineered to off er engineers a user-friendly solution for telecom, networking and data storage applications, holding PCI graphics, audio and storage cards securely in place. Meanwhile, the cap allows designers to designate access through a range of standard and custom colour options.


HISTORY IN AUTOMOTIVE DESIGN A


s automotive manufacturers gradually take on more responsibility for the


performance of a vehicle over its life cycle, they are increasingly looking for ways to lower installation costs and facilitate quick access to critical vehicle components, resulting in faster service calls. Simultaneously, OEMs are also under pressure to meet consumer demand for


superior ergonomics and motorists demand greater convenience. Amid the rapid pace at which


new materials and components are being introduced to automotive design, the DZUS fastener has stood the test of time. First patented by William Dzus in the 1930s and incorporated under the Southco brand in 2004, the fastener was originally designed


for the aerospace market. Now, it is a proven and reliable fastener commonly used within many vehicles in the automotive sector, off ering fast and repeatable access to components, no loss in strength under continued operation, and retention of hardware in the panel. As such, the fastener enables faster service calls and lower maintenance costs. ●
