The Weidmüller clamping yoke
system vibration-resistant. The vibration resistance
depends the magnitude the
spring force the leaf clamp, and
this force also compensates the
relaxation phenomena which occurs
in the conductor. The
relaxation the conductor is
compensated for the elastic
behaviour the Weidmüller
clamping yoke.Connection systems
The principle vibration resistance
Clamping yoke
As the clamping screw tightened,
the ensuing force causes the upper
threaded part spring back and
exert locknut effect the screw. therefore not
necessary retighten the clamping

Leaf clamp
The distance “d” between the shaft
of the clamping screw and the leaf
clamp causes elastic deformation
of the spring the screw is
tightened.
TOP
Like with the clamping yoke, the
force exerted the steel lever as
the screw tightened forces apart
the two threaded parts the TOP
connection.
It therefore not necessary to
retighten the clamping screw. This exerts locking
effect the screw and guarantees
excellent vibration resistance
