Self-locking Cable Clamp

      This article describes a self-locking clamp for optical
cables.

      Electrical connectors for machines which, during their
operation, are connected to mains voltage have to be suitably
protected.  The computer industry has developed tension relief cable
connectors which prevent the machine on which they are provided from
being accidentally disconnected.

      In computer equipment with optical glass fiber transfer cables,
special measures for protecting such cables are indispensable.  For
this purpose, the bending and tensile forces at the cable outlet have
to be reduced to a minimum.

      As shown in the figure, the cable is inserted in an S-shaped
recess  in the arrow-marked direction.  The top end of the recess is
provided with a clamping plate which is eccentrically supported on a
pivot and designed such that the cable is forced past it.  When the
cable is tensioned, the friction turning the clamping plate increases
the surface pressure exerted on the cable.  As a result, the blocking
effect occurring in the cable's direction of movement prevents the
plug connector, preceding the cable clamp, from being accidentally
disconnected or loosened. Excess surface pressure on the optical
cable is avoided by a stop provided on the housing.

      A mirror-inverted design of the housing with an additional snap
connector permits the simultaneous use of two cables.  Additional
elements preventing the cables from being...
