16、CONNECTOR INTERFACES - Part 9: Type DS connector family 1 Scope This part of IEC 1754 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 cylindrica
17、l, spring-loaded ferrule of a 2,5 mm nominal ferrule diameter. The optical alignment 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
18、 connector interface Interface 9-2 : Jack connector interface The type DS connector 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 ja
19、ck is retained to a printed board housing which is fixed to a printed board. The 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 fol
20、lowing standard interfaces are intermateable. Interface 9-1 mates with interface 9-2.

It

Ferrule compression force shall be from 7,8 N to 11,8 N when the position of the optical datum target from the datum X is moved in the range of 1,775
