19、754 defines the standard interface dimensions for type DS family of connectors. 2 Description The parent connector for type DS connector family is a single position plug connector which is characterized by a cylindrical, spring-loaded ferrule of a 2,5 mm nominal ferrule diameter. The optical alignme
20、nt mechanism of the connectors is of a rigid hole or a resilient sleeve style, and is self-contained within the jack connector. 3 Interfaces This standard contains the following standard interfaces. Interface 9-1 : Plug connector interface Interface 9-2 : Jack connector interface The type DS connect
21、or family is a connector set of a plug and a jack configuration, and is generally used as a plug-in type backplane connector. The plug is retained to a backplane connector housing which is mounted to a backplane. The jack is retained to a printed board housing which is fixed to a printed board. The
22、plug mates to the jack by plugging the printed board into the backplane. The plug of interface 9-1 and jack of interface 9-2 have a ferrule with a spherically polished ferrule endface, and make physical contact. The following standard interfaces are intermateable. Interface 9-1 mates with interface
23、9-2.

It is noticed that the ferrule is movable by a certain axial compression force with direct contacting end faces, and therefore dimension D is variable. Ferrule compression force s
