Would you like to connect solid or stranded conductors quickly and safely? This is not a problem with the plug-in terminals from the eibabo® technology store. Choose from numerous different versions for a wide range of applications. Best prices, a wide range of additional information and illustrations, fast availability and worldwide shipping characterize our shop. In addition to the company Wago, other well-known manufacturers offer high-quality plug-in terminals. The eibabo® shop stocks plug-in terminals from the brands ABN, Barthelme, Eaton, Finder, Hager, Hellermann Tyton, Kleinhuis, OBO, Phoenix, PROTEC.class, Spelsberg and Striebel & John.
You will find a large selection of clamps for different requirements and areas of application. There is a large number of terminals, which are designed in different designs depending on the wire type and cross-section and thus perfectly match the respective area of application. These include bus coupler terminals, compact connection terminals, box terminals, terminal strips and connection terminals. Depending on the design and area of application, the plug-in terminals have a certain number of slots. Some variants of clamps are transparent. This will help you see if the wire is properly attached.

What are plug-in terminals?
Plug-in terminals is the name for numerous different spring-loaded terminals, spring-loaded terminals, connecting terminals or screw terminals. These are used in electrical engineering to connect wires, cores and lines. Clamping or screwing an electrical conductor offers a safe and maintenance-free connection.
Already knew?
Push-in terminal does not mean that the wire is fixed by inserting it into the terminal. There are also push-in terminals where the wire is held in place with a screw.
The plug-in terminal is also often referred to as a Wago terminal. The clamps were given this designation after the manufacturer Wago. He introduced the spring clamp technology in the early 1950s and has continuously improved it since then. Since the 1970s, the product has revolutionized electrical installation, as screw connections can now be dispensed with in many areas. However, this does not mean that clamps with screw fastening are no longer used. In this catalog you will also find clamps with screw connections, also known as luster clamps or Euroclamps.
Where are plug-in terminals used?
Push-in terminals are one of the most popular methods of making electrical connections. Solid or stranded conductors can be connected quickly and safely with the help of plug-in terminals. In our shop we offer different types of clamps, which are suitable for different areas of application. For example, there are terminals for use in the following branches of industry:
- electrical industry
- automotive industry
- telecommunications
- communications engineering
- Plant construction and mechanical engineering
- computer engineering
- medical technology
In the private sphere, plug-in terminals are mainly used to clamp rigid wires in junction boxes, in control cabinets, in domestic installations or to connect lights.
What should I know about plug-in terminals before buying?
Electrical installations and electronic circuits almost always have to be connected to external devices, power sources, inputs or outputs. These connections are made using plug-in terminals. These are available in many different types, shapes, sizes and denominations. Choosing unsuitable plug-in terminals can cause some difficulties. These can be simple space problems within a terminal box or have serious consequences such as fires. Therefore, we would like to introduce you to some types of plug-in terminals. Although there are many other variants, we limit ourselves to the most well-known products, which can be found in almost every sector. The areas of application range from classic household wiring to automated applications.
Push-in terminals
So-called push-in terminals use small spring-loaded contact levers. The highlight is that the electrical conductor can be pushed into the terminal without tools. However, it is not possible to pull it out just as easily. The wire is effectively held in place. Compared to the screw clamp, this fixing method offers the advantage that the wire cannot be damaged during installation. If you want to release a pinched wire, pull on the wire while making an alternating twisting motion. In this way, you release the plug connection without damaging the plug-in terminal, the spring mechanism or the electrical conductor.
Please note
Not all push-in terminals are designed for multiple use. Some clamp springs hold the wire 'forever'. If you want flexibility in your installation for modifications or repairs, choose push-in clamps with a lever-release lever. This releases the wire again when actuated.
When choosing the right terminal, pay attention to the appropriate cable cross-section. This should always correspond to the permitted nominal cross-section of the terminal. You will typically find this information on the packaging. An electrical conductor that is too thin cannot be securely clamped and held.
terminal blocks and terminal blocks
Terminal blocks accept a single wire and connect it to a circuit or other system. Terminal blocks are available in a variety of sizes, ratings and shapes and are available in rows. Each terminal in a row is only fitted with one wire. This variant of the plug-in terminal is useful for connections that are subject to regular maintenance, repair or modification. Terminal blocks always have a mechanically strong body made of plastic or another insulating material. In addition to the spring attachment, versions with a locking lever are also available. The wire is inserted and a clamping lever holds the electrical conductor in place. Another common connection method is to use a screw.
TIP:
Great care must be taken when tightening the screw. Overtightening the inserted cable can damage the electrical conductor. An unreliable or potentially dangerous connection would result.
In some variants, the screw presses the electrical conductor against a metal body. On other screw-connection terminal blocks, the screw presses onto a flat metal head. This in turn presses the wire against a metal insert.
Pluggable terminals
Pluggable terminals have a cable entry to allow the wire to be connected. On the other hand, these terminals have a plug output and thus offer a pluggable connection for further installation. This type of plug-in terminal is useful when the connection must be frequently disconnected for maintenance or inspection. These contacts are usually screwed.
barrier clamps
Barrier clamps also use screws as the mechanism for holding the electrical conductors. Barrier clamps often have more than one connection point for multiple cables or wires. These connection points are isolated from each other (barrier). Depending on the model, barrier terminals have small covers or housings. These protect the cabling additionally. Barrier clamps find application in house wiring and other high voltage connections where arcing or potential short circuits must be avoided.
