Electrical device addressing arrangement

摘要

An address module 20 for providing an electronically readable address for a device comprises a plurality of elongate contacts 21 and a printed circuit board 22. The contacts 21 have one end for insertion into corresponding address cavities (13, Fig. 7) of a connector housing and are mounted to the printed circuit board 22 at their other ends. The printed circuit of the printed circuit board 22 is arranged to electrically connect together various contacts 21 to determine the address. Insulating bushes 23 may be included around the contacts 21 and a plastic coating 24 may be applied to cover the printed circuit board 22 and part of the insulating bushes 23. The contacts 21 may also include spring clip releasable locking means 25 to secure the module 20 to the connector housing. An extraction tool (70, Fig. 8) may be used to separate the address module 20 from the connector housing.
