Hirose – New low profile, wire-to-board connectors for power supplies

Hirose has introduced the DF58 series to deliver a space-saving, low profile, Wire-to-Board connectivity solution for miniature applications. The connector range consists of crimp sockets and headers in a single row. The mated height profile is minimised to 1mm and the depth to 4.97mm to reduce the space needed on the board. Although the connector is miniature in size the power rating is not comprised. A high current rating capability of 3A (using the two contact version with 28AWG cable) can be achieved to support power supply applications. Secure connection is guaranteed with the ViSe (Vertical-insertion Swing-extraction) double-locking mechanism. The crimp socket is mated to the header in a vertical direction; however it is guided in at an angle to engage with the positive lock. This ensures high retention force in the upper direction and prevents the cables from easily being disconnected. The friction lock prevents incomplete locking and floating after mating. Highly reliable two-point clipping contacts are utilised to stabilize contact resistance and reduce temperature rise. Furthermore, a long effective mating length of 0.29mm is achieved even though the low profile mated height is low at only 1mm.
