QTH-150-02-H-D-A is a kind of rectangular connector within the arrays, edge type, mezzanine (board-to-board) classification. Its main application field lies in computers, peripherals, and communication systems that passively and actively require an interface between two printed circuit boards or boards and cables.

QTH-150-02-H-D-A connector is known for its two-level, dual-row, board-to-board power and signal interface. The major construction of the connector is included of two over-molded parts, one receptacle housing and one plug housing. On the receptacle, the signal is transmitted through surface-mounted, flat body contacts, as well as through cage contacts that are pre-loaded. The connector also features a protective lid, which is attached to the plug housing and helps to protect contacts from mechanical damage, EMI/RFI, and droplet incursion during the assembly process.

The working principle of QTH-150-02-H-D-A connector involves the internal configuration of contacts and housings. The receptacle housing has two rows of surface-mounted contacts—each row containing 20 metal pieces—and a secondary header. Each row of contact pieces is connected to one metal spring inside the housing in order to assure reliable contact connection with the insert. On the plug housing, a combination of both 20-position and secondary headers are present. Each of the 20-position headers contain both cage contacts and flat bodies, which provide a medium for signal transfer.

When the two halves of the QTH-150-02-H-D-A connector are mated, the metal springs inside the receptacle housing are compressed and biased towards the corresponding contact pieces in the plug housing. This creates a physical connection between the two parts and allows signal transmission. Furthermore, the protective lid on the plug housing helps to secure the connection and reduce the effects of EMI/RFI and mechanical stress.

In conclusion, QTH-150-02-H-D-A connector is ideal for computers, peripheral devices, and communication systems that require higher signal transmission accuracy, durability and fast assembly. The connector features a two-level, dual-row board-to-board power and signal interface with surface-mounted contacts and pre-loaded cage contacts, as well as a protective lid. The connector’s working principle involves the internal configuration of contacts and housings coupled with compression and bias created when the two elements are connected.
