<h2>Introduction</h2>The QFS-078-02-H-D-A-P-TR is a rectangular connector array, edge type mezzanine connector from the QFS series family. It is designed to provide Customers with the best performance required and meets the international standard. This connector is a typical mezzanine connection device that can connect two different boards and transmit signals or power quickly. <h2>Application Field</h2>The QFS-078-02-H-D-A-P-TR is suitable for the applications that require high performance connectors for signal or power transmission, and it can also connect two different boards. It is mostly used in the appliance such as digital camera, video monitor, laser printer and LCD. Furthermore, this mezzanine connector also can be used in heavy industries such as aerospace, military, industrial automation. In addition, it also can be used in telecommunication, medical systems, power industry, automotive industries, and etc. <h2>Working Principle</h2>The QFS-078-02-H-D-A-P-TR is a mezzanine connector which consists of two main parts: a male part which contains the pins and a female part which accommodates the pin outlets. With the help of the spring loaded mechanism, the male part has a high contact force and non-uniform pressure distribution which ensure the reliable connection between the two boards they connect. In order to provide a reliable connection between the board-to-board connection, the QFS-078-02-H-D-A-P-TR uses a pin terminal that is perfectly matched to a printed circuit board (PCB). The pin terminal is composed of two parts: pin and insulator. The insulator has a hard surface which provides the lowest contact resistance between the pins of the connector and the circuit board. The pins are made from high-grade alloy that provides superior durability and better reliability in harsh environments.In order to ensure a good connection and secure latch, the QFS-078-02-H-D-A-P-TR is installed with a locking latch mechanism. The latch device has an inner grooved design which allows the connector to be tightly locked into the receptacle. Once the connector is locked into the receptacle, it will remain firmly in place and no damage will happen due to vibration and shocks. Furthermore, the QFS-078-02-H-D-A-P-TR has a high-speed transmission performance that can meet the needs of many high-speed application. It also provides a compliant and reliable contact retention force that is suitable for many challenging environments. In addition, this connector is made with RoHS compliant materials and it is designed to meet the industry standards for high performance. <h2>Conclusion</h2>The QFS-078-02-H-D-A-P-TR is a rectangular connector array, edge type mezzanine connector from the QFS series family. It is designed to provide Customers with the best performance requirement. This connector is suitable for applications that require high performance connectors for signal or power transmission, and it can also connect two different boards. From the above discussion, we have learned the application field and working principle of the QFS-078-02-H-D-A-P-TR rectangular connector array, edge type mezzanine connector. It is a mezzanine connector which consists of two main parts and uses a pin terminal that is perfectly matched to a printed circuit board (PCB). Furthermore, it also has a locking latch mechanism and provides high-speed transmission performance.
