Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board)

QFS-078-02-H-D-RA-PC4 is a type of rectangular connector designed for applications that link boards or electronic components in a backplane and provide rapid connections or disconnection of circuits. This device has an 8-position male header and a 7-position female socket and is designed for rugged dependable performance in extreme environmental and mechanical conditions.

Application FieldQFS-078-02-H-D-RA-PC4 is widely used in various industrial, medical, automotive and aerospace applications. It can be used in some of the most demanding environments including high shock and vibration, extreme temperatures, high humidity, dust, and corrosive materials. It is very limited in space when compared to other more sprawling connectors.This type of rectangular connector is often used in mezzanine board-to-board applications. It is suitable for applications that need space saving and high density such as test and measurement,industrial automation, medical, and communications.FeaturesQFS-078-02-H-D-RA-PC4 connectors offer some advantages including multiple contact points that are tighter and smaller than conventional round connectors,long service life and secure connections,low crosstalk,high-speed signaling,high heat resistance, and others.These connectors also provide the user with the ability to perform insulation displacement on the IDC contacts that help to reduce labor cost and installation time. This type of connector also offers diagonal design patterns which facilitates connecting two boards at right angle or mezzanine board interconnections. It supports motor vehicle standards used in modern vehicles, providing optimum air tightness and environmental resistance.Working PrincipleThe working principle of the QFS-078-02-H-D-RA-PC4 connector is based on a positive locking mechanism that couples the male and female components together. The secure connection is achieved through robust latch systems that keep the connection in place once engaged.The male-female connection is made through insulation displacement contacts (IDC) that crimp the insulation jacket of the wire to the contact tab on the connector. This is accomplished by pressing the tab against the conductor of the wire, thus establishing a secure electrical path.When the connection is made, the latch system, which consists of two tapered tabs, locks the male and female connectors together. Once the connection is securely locked, it cannot be released without pressing the latch release tabs.ConclusionQFS-078-02-H-D-RA-PC4 is an advanced rectangular connector that is designed for use in high-density, space-constrained applications that require secure manufacturing quality. It provides reliable connections and a long lifespan, and offers an extensive array of features that result in maximum performance. This connector also supports the latest automotive standards for air-tightness and environmental resistance.
