Hirose unveils 2.2mm pitch, wire-to-board connector for power supplies
Hirose have introduced the DF61 series to meet with the increased demand for compact, high powered wire to board connectors offering advanced reliability for power supplies. The connector range consists of headers, sockets and crimp contacts that have the capacity to handle up to 4A current rating.
The connector range has been designed with space saving in mind. The two position for example only occupies 38mm2 approximate board space, while the height profile is a mere 2.38mm. Power performance is not compromised by the small size - an impressive 4A maximum current rating per contact can be achieved using the two position connector with AWG22 wire.
High reliability is guaranteed with Hirose’s ’Swing Lock’ offering a unique 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, this engages 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, which provides a tactile click sensation to confirm correct mating. It also prevents the receptacle from floating. The positive lock can withstand a minimum of 10N of cable pull force ensuring that the socket cannot be accidentally removed from the header. A small lever makes the un-mating process very quick and easy. A long effective contact mating length of 0.4mm ensures good electrical continuity. Durability is achieved with 30 mating cycles.
Blade contacts, renowned for their strength are utilised to prevent damage against any cable wrenching forces. On the crimp socket these are positioned within a strengthened housing lance to increase the retention further. On the header, the contacts are perfectly isolated to allow a long creepage distance that permits a high voltage capability of 350V. The termination contacts on the header are fully moulded into the insulator to eliminate any gaps to prevent solder wicking. A long effective contact mating length of 0.4mm ensures good electrical continuity.
