Terminal blocks, or terminal strips, are common wire-to-board electrical connection devices. They are found in just about any electrical device, from consumer electronics to industrial automation. In this article, we will take a closer look at model 1871270000 terminal blocks, and their application field and working principle.

Overview of 1871270000

The 1871270000 terminal block is a plug-in device, with an IEC EN 60 60947-7-1 international standard. It offers both screw and spring clamp connections with a rated current of 30 amps. These devices are designed with a flange on the top that helps to not only make them easier to mount, but also to reduce vibration. The plug-in style also makes them a popular choice for applications that require the flexibility to be moved or adjusted on the fly without completely disconnecting, such as machine tool operations.

Application Field of 1871270000

The 1871270000 terminal block can be used in a variety of applications. They are often found in factories and workshops, providing reliable electrical connections for equipment. They are also well-suited for industries that require rapid and precise movement, such as robotics or automation, as the plug-in style allows for larger cables to be connected quickly while the flange helps to reduce vibrations. They are also commonly seen in combination with protective devices, such as earth leakage current monitoring, for added security.

Working Principle of 1871270000

The 1871270000 terminal block is designed to be easily assembled and provide secure connections. Each terminal block has two plug openings, one on each side, for two electrical cables. The plug openings are designed to fit the wire insulation easily, and a short screw thread runs along the bottom to connect to a metal terminal base. When the cables are connected, the terminal block is secured with a tightening nut.

Inside each opening is an internal contact, which grips the metal core of the cable. These contacts are designed to create an electrical connection between the cables, making a secure connection with minimal contact resistance. Additionally, the inner contacts are mechanical barriers, helping to protect the cables from possible damage.

Conclusion

The 1871270000 terminal block is a popular wire-to-board device, often used in industrial settings and automation. With an IEC EN 60 60947-7-1 international standard, they offer both screw and spring clamp connection options and can handle up to 30 amps of current. They are easy to assemble and provide a secure connection between two cables with a low contact resistance. The internal contact block also helps to protect the cables from any accidental damage.
