QTH-040-04-H-D-DP-A is a type of rectangular connector array that has been designed to provide high performance connections between circuit boards, typically within electronic or telecommunications equipment. It is a mezzanine connector system, meaning it is a board-to-board connector and is suitable for equipped with standard printed circuit boards (PCBs). Depending on the mounting type, QTH-040-04-H-D-DP-A is available in a range of different pin sizes and configurations, with a variety of grounded, surface mount or through hole options available.

Application field

QTH-040-04-H-D-DP-A is primarily used in the telecommunications, computer and associated equipment industries. It is designed to create a secure and reliable connector link between two or more PCBs, and is therefore suitable for applications such as motherboards, graphic cards, switching applications, mobile phones, tablets and other data processing and communication equipment. It is also suitable for a range of industrial applications, including automation, medical equipment and factory automation.

Working principle

QTH-040-04-H-D-DP-A connectors are designed with a board-to-board connection, using an array of up to four PCBs. The connectors are constructed using two main components – the mating and housing parts. The female/mating part is typically a one-piece plastic moulded block that has been designed to contain internal contacts. The male part of the connector contains metal pins, which are used to make an electrical connection between the two boards. The two parts are then mated together to form a secure connection. The connection is then secured by latching, clamping or screwing the two connector parts together. The electrical connection is then established and the connection is complete.

QTH-040-04-H-D-DP-A connectors are typically available in two and four row configurations, with different pin sizes and signal line orientations depending on the application. The female and male parts are colour-coded for easy identification and the contact spring forces minimise contact erosion. The connectors also come with shields to protect against EMI/RFI interference.
