QTH-020-02-L-D-DP-A Application Field and Working Principle Overview

Rectangular Connectors – Arrays, Edge Type, Mezzanine (Board to Board). QTH-020-02-L-D-DP-A connectors are a type of array, edge connector that is used for board-to-board mezzanine connections. Primarily used in the aerospace, military and modern electronics industries, QTH-020-02-L-D-DP-A connectors offer an efficient and reliable way to interconnect two boards. The QTH-020-02-L-D-DP-A connectors are a type of rectangular edge connector with a nominal pitch of 0.020 inches. Designed to have both male and female contacts on the end of the connectors, the QTH-020-02-L-D-DP-A connector can easily interconnect two PCBs in conjunction with solder, press fit or crimp termination techniques. Depending on the application, the QTH-020-02-L-D-DP-A connector can come in many different configurations. For example, a QTH-020-02-L-D-DP-A connector can have headers or sockets, or separable contacts. The standard male and female connectors are typically constructed of stamped and formed copper alloy, nickel plated contacts, and UL 94V-0 rated thermoplastic insulators. The contacts, typically constructed of stainless steel, are available in multiple sizes, so that a wide range of wire sizes can be supported. The application for the QTH-020-02-L-D-DP-A connectors vary depending on the particular goal or design; however, due to its small size and high complexity, the QTH-020-02-L-D-DP-A connector is typically used in aerospace and military applications, as a higher power interface for consumer electronics, or in rack-and-stack computer systems. In aerospace applications, the QTH-020-02-L-D-DP-A connector can be used to connect multiple circuit boards in electronics systems, such as in aircrafts, tankers, UAVs, and missiles.* In consumer electronics, the QTH-020-02-L-D-DP-A connectors can provide a higher power interface, such as USB ports or audio/video connections. In rack-and-stack computer systems, the QTH-020-02-L-D-DP-A connectors can provide a high-speed, high-density bus interface for smaller form factor motherboards. The working principle of the QTH-020-02-L-D-DP-A connector is relatively simple. In most applications, the cable and connector are fitted with a single socket or header on one end and a mating socket and header on the other end. When the cable and connector are fully assembled, the male and female sockets or connector pins are aligned to form an electrical pathway. This electrical pathway allows for the electricity to pass freely between the connected devices, enabling signals to be transmitted. The QTH-020-02-L-D-DP-A connector also provides a secure connection to prevent any interference or contamination from outside sources. Thanks to their small size, high performance, and reliable reliability, QTH-020-02-L-D-DP-A connectors have become an invaluable component to many electronics industries, including aerospace, military, consumer electronics, and rack-and-stack computer systems. As the demand for high power, high density, and high performance cables and connectors continues to rise, the QTH-020-02-L-D-DP-A connector will remain at the forefront of providing reliable and secure connections. *Note: The info contained in the statement regarding QTH-020-02-L-D-DP-A connector applications in aerospace, military, and the consumer electronics is intended to provide a general overview and not meant to be taken as a statement of fact.
