Hirose develops 1.2mm pitch, wire-to-board connector for power supplies
Hirose has launched the new DF57H range of headers, sockets and crimp contacts to meet with the demand for smaller yet better performing connectors.
The connector has been designed with space saving in mind. The two positions for example, only occupies around 18mm² of board space while the height profile is a mere 1.4mm. Power performance is not compromised by the small size; an impressive 2.5 amp maximum current rating per contact can be achieved using the 2 position connector with AWG 28 wire.
High reliability is guaranteed with Hirose’s unique ’Swing Lock’ double locking mechanism. During the mating operation the receptacle is inserted into the header at a slight angle by offering the cable end in first and engaging with the positive lock. The mating operation is then finished by ‘swinging’ the other end of the receptacle in to engage with the friction lock. This provides a tactile click sensation to confirm correct mating and also prevents the receptacle from floating. The positive lock can withstand a minimum of 5N of cable pull force ensuring that the socket cannot be accidentally removed from the header. A small lever makes the unmating process very quick and easy. Durability is achieved with 30 mating cycles.
Blade contacts, renowned for their strength, are utilised to prevent damage against any cable wrenching forces and positioned within a strengthened housing lance to increase the retention further. A long effective contact mating length of 0.42mm ensures good electrical continuity. The termination contacts on the header are fully moulded into the insulator to eliminate any gaps and prevent solder wicking.
