Plug on electrical signal cable for compact disc player has conducting rod and sleeve inside outer sleeve with small diameter portion carrying elastic expanding ring

摘要

The conducting rod (2) fits inside an insulating sleeve (11) inside a conductive tube (1). A profiled conducting tip (21) fits on the end of the rod and is separated from the conductive tube by an insulating ring (22). A C-shaped elastic ring (13) with longitudinal slits fits onto a small diameter section of the conductive tube (12). A square of insulating material (24) has a off-center through bore and separates contact pieces (23,25) for the conductive tube and rod. There is an insulating tube (32) fitting inside a housing (3) with a female thread (31) screwing onto a male thread (15) on the conductive tube.
