Introduction
Backplane connectors are generally used in computer systems where information and communication needs to be transported quickly and reliably. The PO51M-P-1.5 is a sophisticated backplane contact type connector that offers a superior level of mechanical properties and electrical performance. It has unique features that make it ideal for a wide range of applications. This article will discuss the application field and working principle of the PO51M-P-1.5 contact type backplane connector. Application Field
The PO51M-P-1.5 backplane connector is suitable for use in a variety of applications, from industrial to medical, automotive to consumer. For example, it can be used in power supplies, PDAs, servers, routers, modems, and other Communication Equipment (CE) and telecom equipment for connection and link grounds. It is also suitable for use in computers, measuring instruments, satellites, and other high frequency and high precision devices. In addition, the PO51M-P-1.5 is manufactured in compliance with established EU and US safety standards and is therefore very safe for the end user. The contacts are designed to provide improved breakout force resistance, insulation, and contact retention. Furthermore, the operating temperature range is very wide, from -55°C to +125°C.Working Principle
The PO51M-P-1.5 is composed of two sub-assemblies: a bottom contact and an intermediate contact separated by a dielectric component. The bottom contact is an electrically conductive element that is mounted upon the connector body and is connected to the leads of the signal board. The intermediate contact is a plastic element that is inserted into the bottom contact and aids in providing electrical insulation. The contact system is designed using FMVSS-28 compliant materials and has excellent retention characteristics. It features two unique elements - a concentric spring and an indenting element - that reduce insertion force. The contact geometry is such that minimal contact force is retained in the mated condition and provides excellent breakout force resistance among contacts. Moreover, the design facilitates self-alignment of the contact system. The contact system is designed such that the top cylindrical element is surrounded by the spring element. This ensures that the mated contact pair is highly compliant, providing maximal electrical contact performance and superior durability. The contact sleeve is heated and partially clover-shaped to ensure proper insertion and removal of the contact system.Conclusion
The PO51M-P-1.5 contact type backplane connector is a sophisticated and highly reliable connection solution. It is suitable for a wide range of applications, from the industrial to the medical, and its unique features ensure excellent electrical performance and retention characteristics. The contact system consists of two sub-assemblies; a bottom contact and an intermediate contact, designed to reduce insertion force and provide a highly compliant contact system for maximal electrical contact performance and durability.
