proved its worth billions of
Weidmüller products over many
decades.
Clamping yoke connection technology
The Weidmüller clamping yoke
system optimum combination of
the specific properties steel and
copper. stainless steel
spring, which fitted separate
housing, guarantees high contact
force between the conductor and
the current bar (tin-plated copper).Connection systems
Free choice connection technology
TOP connection technology
The Weidmüller TOP connection
system ensures that the conductor
can inserted and the clamping
screw tightened from the same
direction. Even flexible
conductors with crimped wire
end ferrules ultrasonic-welded
conductors can connected without
any problems. The TOP
connection system combines the
specific properties steel and copper. spring-stop
plus conductor stop steel housing
ensure optimum connection conditions
and guide for the screwdriver needed
to detach the conductor.
The high contact force guarantees
a gas-tight connection between
conductor and current bar. Both the clamping yoke and
the clamping screw are made from
hardened steel.
The conductor pull-out force for this
system even higher than that for the
tension clamp system.
Leaf spring connection technology
Weidmüller’s patented leaf clamp
connection system screw
connection system for large conductor
cross-sections. The insertion large
conductors into the clamping point is
made easier here the fact that the
clamping unit can removed first.
And that completes the connection!
No tools are required and the result
is reliable, vibration-resistant and
gas-tight connection.
The conductor can then placed
directly the current bar before
re-inserting the clamping unit and
tightening the screw grip the
conductor. Treating the copper this way
ensures low contact resistance
and high corrosion resistance. This clamping yoke
arrangement generates the necessary
contact force. The
compensating effect the spring
ensures secure contact for the
lifetime the terminal. Such arrangement eases
the wiring work certain installations,
e.
Tension clamp connection technology
The Weidmüller tension clamp
system functions similarly the
tried-and-tested clamping yoke.

Technicalappendix
W.g. The clamping yoke
presses the incoming conductor
against current bar made copper
or high-quality brass. The spring,
made from high-quality rustproof and
acid-proof steel, pulls the conductor
against the tin-plated copper current
bar. The hardened
Weidmüller clamping yoke ensures a
gastight, vibration-resistant connection
between conductor and current bar.
PUSH IN-connection technology
In our PUSH connection
technology the stripped solid
conductor simply inserted into the
clamping point far will go. Here
again, the mechanical and electrical
functions are kept separate.
