World’s First Spring Terminal for Conductor Cross-Sections up to 185 mm

July 31, 2015

WAGO’s new Power Cage Clamp high-current terminal blocks make it possible to connect conductors with cross-sections up to 185 mm with spring pressure connection technology. They are vibration-proof and maintenance-free, without having to rely on preparation intensive bolts or clamping yoke connection technology. Not only does this save a lot of time during cabling, but the high contact forces ensure an optimal and gas-tight contact at all times.

Why You Should Use Cage Clamp Terminal Blocks

March 25, 2015

Hi, Adam Ring with Innovative-IDM.  I wanted to take a few minutes and talk about the battle between the screw terminal and the cage clamp. So, why do people choose one or the other? Well, let’s just look at some of the basic facts. On the screw terminal, when you strip a wire and insert it into a screw terminal, the tightest that that’s ever going to be is the connection at the time you actually torque that screw driver down. From that point on it’s only ever going to get looser. Now when you talk about cage clamp terminal, when you strip the wire and insert it into the cage clamp, that’s actually the loosest that connection ever is. And as that wire then starts to take the shape of the terminal and the wires kind of splay out and basically mold to the shape of the terminal, it’s actually going to get tighter over time because of the spring force that’s holding that wire in place.

So, with temperature cycling as that wire has current running through it and it heats up and cools down and heats up and cools down, it’s going to be expanding and contracting and so forth. Well with the screw terminal, that’s only going to force that screw to back out and get looser and looser over time, whereas with the cage clamp with its spring technology, the spring actually compensates. As the wire expands, it expands, when the wire shrinks back it shrinks back with it and so it always maintains the right amount of tension on the wire for the application.

Now there’s also industrial applications; there’s typically a lot of vibration that is experienced. With a screw we all knows what happens when it’s around vibration, they tend to loosen up. With the cage clamp, vibration typically doesn’t matter. It moves and it adjusts and responds to the vibration without coming loose over time.

Now think about what it costs if you’re having to install hundreds of terminals in a given control panel. If you’re having to screw and tighten down each and every terminal, that’s going to take quite a bit of time. But with the cage clamp, all you basically do is insert a screwdriver, insert your wire, remove the screwdriver and it’s done. You get the same great connection every time. The other thing to consider is first thing in the morning when your fresh, you’re probably going to be tightening down those screws a lot tighter than the last one at the end of the day when you’re kind of tired. So you get a variation of how tight those wires are. And so then what ends up happening is once that panel gets installed in a machine, you’re going to start having loose connections and that’s going to potentially cause a machine to go down and cost you extra money.

So you always want to make sure that you use the right product for the right application. In the case where you have temperature cycling and vibration and you’re looking for the most efficient and best cost to connect your wires cage clamps are definitely the leg up.

WAGO: High Current PCB Terminal Block

November 28, 2013

Terminal Block

The new 2716 Series High Current PCB Terminal Block features Lever-Actuated CAGE CLAMP spring pressure terminations. The convenient integrated operating lever allows for simple, intuitive terminations of conductors sized 16-6 AWG, up to 65A/600V.  rather than Velocity mode. This requirement leads to the use of a servo operating in Torque mode even though a servo in Velocity mode might be recommended with an overriding torque limit. Therefore, the servo normally operates as a constant-torque drive, but if the filament breaks, the velocity is limited to the programmed value. The traversing arm is usually driven by a smaller servo.

WAGO Cage Clamp Wire Connectors; Screwless with Spring Pressure

June 4, 2013

The CAGE CLAMP® is the internationally known trademark of the cage clamp spring pressure connection system which was first introduced in 1977 by WAGO and available from Innovative-IDM.

It is a universal clamping system for solid, stranded and fine-stranded conductors with rated cross sections from AWG 28 to 2 (0.08 mm² to 35 mm²).

The clamping unit also consists of only two elements: the cage clamp and the current bar. These two form a self-contained contact unit, which does not transfer any load to the insulation housing. The CAGE CLAMP® is made of high-quality chrome nickel spring steel. The current bar consists of electrolytic copper and has a mixed tin surface.

Irrespective of the type of conductor, the CAGE CLAMP® has to be opened using a screwdriver to introduce the conductor. After the conductor has been inserted into the clamping unit and the spring been released, the conductor is clamped safely in a defined contact zone with a pre-programmed cross section-adequate clamping force. This spring clamp system rules out the possibility that a conductor is inserted into the clamping unit but not secured.
