From 1 January 1997, all IEC publications have the number 60000 added to the old number. For instance,

6、 IEC27-1 has been renumbered as IEC60027-1. For a period of time during the change over from one numbering system to the other, publications may contain identifiers from both systems. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists

47、be connected to a round cable. The shielding braid of the cable shall be connected to the conductive shell of the housing, and the insulation of the cable shall be retained by a strain relief device. The signal wires shall be connected either directly to the female contacts by crimped or insulation

48、displacement connections (IDC), or to an internal printed circuit board by means of a transition device. The cable-to-board connectors are recommended for the use in three different applications: Application a, rear plug-up connection; Application b, connection to backplane; Application c, connectio

49、n through front panel. See Figure 1 for location of the above-mentioned reference letters. Depending on the application the fixed board connectors shall be attached to the backplane or to the front panel through the press-in connections of their shielding frames.
