Terminal Blocks - Accessories - Jumpers

Jumpers play an important role in the field of electrical and electronic engineering. Commonly used interminal blocks, jumpers are specialized connecting components in the field of signal transmission or circuit control. The jumper used most often is the 474139, a single-piece folding terminal which is easy to install and require minimal wire termination. In this article, we will discuss the 474139 application field and working principle.

Application Field of 474139 Jumpers

474139 jumpers are commonly used in terminal blocks where its small size, easy installation, and a strong connection make it an ideal choice. The 474139 is most popularly used in switch cabinets, panel boards, gate boards, and machine control systems, where it serves to connect two points of a circuit without causing any disruption to the flow of the current. Additionally, the 474139 is also popular in telecommunication systems, particularly in low-voltage systems, where its wide working temperature range (-40 to 155℃) makes it a reliable choice.

Working Principle of 474139 Jumper

The jumper 474139 is a single-piece folding terminal jumper that uses two contact bridges to serve as a bridge between two sections of the circuit. It is composed of two connecting plates with very limited contact area. The plates are connected by a connecting shaft with holes on both sides. When the jumper is installed, a hole in one of the connecting plates is connected to a source point (one side of the circuit) while the other connecting plate is connected to the termination point (the other side of the circuit).

The working principle of the 474139 jumper is quite simple. When current is passed through one plate, it is conducted through the connection shaft to the other plate, thus bridging the two points of the circuit and sending current through. In this way, 474139 jumper quickly and easily bridges two points in a signal transmission or circuit control system, without any complex wiring or installation of additional components.

Conclusion

In conclusion, the 474139 jumper is a popular jumper used primarily in terminal blocks in a wide variety of electrical, telecommunication, and industrial systems. Due to its size, easy installation, and wide working temperature range, it is an ideal choice for connecting two sections of a circuit. Its working principle relies on the simple concept of two connecting plates connected by a connecting shaft, thus bridging two points of a circuit quickly and easily.
