QMS-026-05.75-L-D-A-GP-K-TR application field and working principle

Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) connectors provide a uniquely flexible means for interconnecting printed circuit boards with different pitches and sizes such as edge boards, edge cards, and flex ribbons. They are ratchet-style connectors that feature receptacles which are designed for use with mateable plug-in connectors. These connectors offer high density, high reliability, and mechanical ruggedness for harsh environment use. The primary application field of QMS-026-05.75-L-D-A-GP-K-TR is for mezzanine-style connectors that target applications involving board-to-board connections.

Working Principle

QMS-026-05.75-L-D-A-GP-K-TR have a set of spring-loaded, curved arms or “fingers” at their rear side. When a plug is inserted into the connector, the fingers latch onto it and apply spring force towards the mating surface. This ensures proper electrical contact between the terminals on the plug and its mating surface. It also provides a secure mechanical fit. Since the mating surfaces on QMS-026-05.75-L-D-A-GP-K-TR are designed in a tongue and groove pattern, the springs help keep the plug and mating surface aligned when inserted.

To remove the plug from the connector, there is an ejector on the connector’s foot. Applying pressure on the rejector will release the plug from the locking arms. Once the plug is in place, the mechanical and electrical connection is secure and reliable.

Applications

The primary application field of QMS-026-05.75-L-D-A-GP-K-TR is for mezzanine-style connectors that target applications involving board-to-board connections.
