ODU MACThe Concept of Springtac SpringwireContacts.The springwire contact is the invention of Otto Dunkel.The Figure shows a Springtac socket and solid pin.The socket has a multitude of preformed springwires.The springwires are parallel to the plugging direction.They form a flexible cage, with one end fixed at thebottom of the socket, the other end free to move.The springwires are independent from each other andmake contact with the surface of the pin.This arrangement creates in the mated condition analmost constant normal pressure over the entire contactsurface of the pin. A springwire socket for a 1.02 mmdia. (AWG 20) pin has about 19 springwires. Thenumber of springwires increases with the size of thecontact. This results in many contact points betweenpin and socket, creating a large contact area for excellentcurrent transmission. Springtac contacts are availablefrom 0.6 mm dia. to more than 50 mm dia. Theycan be supplied with solder, crimp, or threaded studtermination.Contact retention in a connector insulation body is viamilitary-style contact clips.The outstanding advantages of ODU Springtaccontacts are:❏❏❏❏❏❏❏Very high contact reliabilityLow contact resistanceHigh current carrying capabilityHigh resistance to vibrationLow mating and demating forceHigh number of mating cyclesLong service lifeKontaktdrahtOberflächenveredelungBuchsenwandBerührungsflächeKontaktstiftODU Steckverbindungssysteme GmbH & Co.
