QSH-090-01-L-D-A-K Application Field and Working PrincipleQSH-090-01-L-D-A-K forms part of a range of edge type connectors that are designed to suit mezzanine, board to board applications. These connectors come with soldering areas that feature two rows of nine edge type contacts and pins of 0.635 mm, or 0.025 inches, pitch. Solder tails are also supplied with the QSH-090-01-L-D-A-K, to enable easy installation.QSH-090-01-L-D-A-K connectors are available in a variety of styles and shapes, and feature two mating parts that can be mounted to either the same board or as a two part system. It can also be used to bridge one or two components on a mezzanine type board. The number of contacts and pins can range from nine to thirty-six, and these are normally located on either a single or a double row.The most common form of QSH-090-01-L-D-A-K components are those with nine contacts. All parts are made of thermally stable resin and are designed to provide exceptional electrical performance. The connectors also have low insertion and extraction forces. This is down to two end locking tabs that provide reliable and repeatable connection.The application field of QSH-090-01-L-D-A-K is very broad. It is suitable for connecting adjacent boards or components in mezzanine boards, for example devices such as system printers, etc. The connectors can also be used in communication and networking applications, for power supplies, industrial and commercial displays, and in a wide range of applications in instrumentation, medical and automotive systems.To understand how the QSH-090-01-L-D-A-K works, we must first understand what a ‘mezzanine’ type board is and how it is used. A mezzanine board is a type of printed circuit board that is designed to be easily attached or removed from a larger board. It contains a single printed circuit trace on the board, enabling the connectors to be soldered to the board.The way QSH-090-01-L-D-A-K works is that it uses tabs to provide a secure connection to the board. The connectors, when mated, wrap the board trace in between two sets of tab contacts. This ensures that the connection is firmly secured and that no further attachment is required. This also prevents ‘mistakes’ or premature unplugging.QSH-090-01-L-D-A-K is also designed to provide reliable electrical performance and signal integrity. The connectors feature high contact density and are designed to minimize cross talk and inductance. Furthermore, the connectors have excellent loading capability which helps to prevent electrical signal degradation over time.QSH-090-01-L-D-A-K connectors can also provide very active performance as they allow for efficient power distribution. Mechanical stability is also ensured by the use of locking tabs which ensures a secure and reliable connection between the boards. These tabs also prevent any unwanted movement during insertion or removal of the connectors.In conclusion, QSH-090-01-L-D-A-K connectors are used in a wide range of applications, including but not limited to, mezzanine, board to board and double connectors. The connectors are designed to provide excellent electrical performance and signal integrity. They feature high contact density and are designed to minimize crosstalk and inductance. Furthermore, the connectors have excellent loading capability and also provide a reliable and secure connection. Ultimately, QSH-090-01-L-D-A-K connectors are ideal for a range of applications requiring a high performance and reliable connection.
