Technical data
Screw connection
Screw connection systems are easy
to handle and are known all over the
world; this is an important point to con-
sider for mounting and maintenance
tasks which are spread throughout
the world. Screw connections which
are based on a clamping-type body offer a gas-tight, vibration-
proof connection for connected wires. They also feature excel-
lent contact force. This system is thus perfectly suited for use in
corrosive environments. The passivated silver surfaces ensure
even more resistance against corrosion. The Weidmuller clam-
ping-style body is perfectly suited for connecting solid-core and
flexible stranded conductors. A wire-protection frame ensures
that finely-stranded wires will not splice off.
Tension clamp connection
The Weidmuller tension clamp
system functions similarly to the
tried-and-tested clamping yoke. Here
again, the mechanical and electrical
functions are kept separate. The
tension spring made from high-quality
rustproof and acid-proof steel pulls
the conductor against the tin-plated copper current bar.
Treating the copper in this way ensures low contact resistance
and high corrosion resistance. The compensating effect of the
tension spring ensures a secure contact for the lifetime of the
terminal.
Push-In connection technology
With the Push-In connection system,
the stripped solid-core conductor is
simply inserted into the terminal point
until it butts against the end stop.
And then its ready. No tool is
required and the result is a reliable,
vibration-resistant and gas-tight connection. Even flexible
conductors with crimped wire end ferrules or ultrasonic-welded
conductors can be connected without any problems.
A stainless steel compression spring, which is fitted in a
separate housing, guarantees a high contact force between the
conductor and the current bar (tin-plates copper). The pull-out
force for this system is even higher than that for the tension
clamp system. Spring and conductor stops in a steel housing
ensure optimum connection conditions and a guide for the
screwdriver needed to detach the conductor.
In the crimping method, the wires
are fed into a metal sleeve, which is
then squeezed together with a special tool. The connection is
now corrosion and vibration proof. The contacts can be
crimped on the conductor outside of the connector and then
inserted into the connector.
The advantage of the axial screw
connection is the small space taken
up by the contact. The axial screw
connection is also extremely easy to use. To make up the con-
nection, the tool and conductor are held in a line. Just three
steps are needed for a secure connection: strip the conductor,
insert the wire into the contact chamber, screw in the contact –
that’s all!
Of course, all of Weidmuller’s wire connection systems are
gas-tight.
Weidmuller offers RockStar
connectors with five different
connection systems
There are five common types of connection: tension clamp
connection, screw connection, crimping, axial screw connec-
tion and push-in technology.
