QTH-020-01-L-D-DP-A-K-TR Application Field and Working Principle

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

Rectangular connectors are one of the most common and commonly used connectors in the industrial and electronics field. They are used as interconnects between circuit boards, cables, and other electronic components, and they can be used in a variety of ways due to their modularity. The QTH-020-01-L-D-DP-A-K-TR is an example of an edge type array mezzanine connector, and is designed to provide a reliable electrical connection with ease of assembly for applications with a high degree of density. This type of connector can be found in a wide range of configurations and sizes.

The QTH-020-01-L-D-DP-A-K-TR Connectors: Applications and Advantages

The QTH-020-01-L-D-DP-A-K-TR connectors are a multi-row, edge-type mezzanine (board-to-board) connector, configurable up to fourteen rows. The connectors offer high packing density, reliable performance, and small mounting footprint. Because of the high packing density, the Connectors are ideal for compacting applications while allowing multiple-row signal connections without overcrowding.

The connectors are designed to meet the requirements for designations such as the UL950, CSA LR96977-1, and IEC60950 standards. This means that they have been tested and verified as capable to provide reliable performance in extreme temperatures and vibration as well as electromagnetic interference (EMI) protection. The design, which includes a positive latch mechanism, ensures secure connections and has been tested to withstand more than 20,000 mating cycles per spring to meet the most rigorous requirements.

QTH-020-01-L-D-DP-A-K-TR Connectors: Working Principle

The QTH-020-01-L-D-DP-A-K-TR connectors are designed for board-to-board connections, with two identical connectors, one on each board. The connectors are held in place on the board with a two-part clamp, which helps to provide a secure connection. The connector contains two rows of gold-plated pins that can mate to either an internal or an external row on the other board.

During mating, one of the connectors bumps slightly inward while the other connector experiences a slight outward bump. This results in a positive locking action, as the connectors latch together and form a secure connection. The gold-plated pins then establish electrical contact with each other, creating an electrical connection that is reliable and withstands thousands of mating and un-mating cycles without degradation. The connectors are also designed with a special contact area that helps to shield the connections from dust, dirt, and other contaminants, ensuring a reliable connection.
