Jumpers serve as connectors between two electrical circuits, such as between two blocks of a terminal strip. This article will examine the application field and working principle of JB1-04/J jumpers, one type of terminal block accessories.

Application Field

JB1-04/J jumpers are commonly used on terminal strips, but can also be used with a wide variety of other soldering or screw application terminals. This type of jumper is suitable for circuit configurations with different properties, such as direct current, alternating current, digital logic, and so on. Furthermore, as the external insulation of the jumper is composed of non-toxic and flame-resistant ABS material, its environments of use should not contain inflammables or explosives, and it can be used in settings between 0-50°C.

Working Principle

The JB1-04/J jumper comprises two contacts, one end is attached to one terminal of the terminal strip, the other end to the terminal adjacent. Therefore, two circuits can be connected together. The contacts are made of copper coated with tin, protecting the jumper from oxidation. The housing of the jumpers is made from a durable, heat-resistant material.

To ensure effective connection, it’s essential to maintain clean contacts and make sure the terminals of the jumper are inserted properly and aligned. This can be facilitated with a spring loaded slot which helps keep the contact in place and prevents accidental ejection. Additionally, the jumper can also be secured with a latch which keeps the contact in place if the spring is not applicable.

Conclusion

In conclusion, JB1-04/J jumpers is a type of terminal block accessory used for connecting two circuits in various applications. It is composed of two contacts that are made from copper with tin coating, and the housing material promotes heat-resistance. Proper usage of jumpers requires cleaning and ensuring the terminals are properly inserted and aligned.
