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

QMS-078-02-S-D-RA Application Field And Working Principle

The QMS-078-02-S-D-RA is a Rectangular Connector an Edge Type connector for a Board to Board Mezzanine application. The design of the QMS-078-02-S-D-RA, with its double-row configuration and two guide peg-holes, provide efficient connections from one layer of circuit boards to another. The QMS-078-02-S-D-RA is designed to provide electrical contact to conductive pads on the edge of surface mount printed circuit boards.

This particular connector is designed with two guide peg-holes for better alignment during assembly and mating with other circuit boards. It also has two pieces of dielectric material on both sides of the connector, which helps to block electricity from flowing between the two circuit boards. The grounded metal cover has been specially designed to prevent electrostatic discharge and thus ensure better performance.

The connection method of the QMS-078-02-S-D-RA involves using contact pins to connect the two boards. There are two pieces of contact pin posts that are soldered on each board. The contact pins are press-fit into the contact pin posts, providing the circuit connection between the two circuit boards. The contact pins are made from copper, and they are plated with gold for better electrical contact.

The QMS-078-02-S-D-RA connector is used for various different applications including powering up electrical equipment, providing electrical connections in automotive and industrial applications, and as test pins for measuring electrical connections. The connector is well suited to testing applications due to its low profile and double-row design. The contact pins provide a reliable electrical connection while reducing unwanted noises and vibrations within the system.

In summary, the QMS-078-02-S-D-RA is a board-to-board edge connector which is especially suitable for mezzanine applications. It is designed with two guide pegs holes to ensure better alignment between two circuit boards and it also features two pieces of dielectric material to block electricity from flowing between the two layers. The grounded metal cover helps to protect from electrostatic discharge. Finally, contact pins provide electrical connection between the two boards and are plated with gold to ensure better electrical contact.
