72/7VZ application field and working principle

72/7VZ terminal blocks are parts of a multi-conductor system, used in a wide variety of electrical installations for the termination of a variety of wires. They are ideal for a number of industries including the automotive, industrial, commercial, telecommunications, and aviation industries. 72/7VZ terminal blocks are used in a wide range of applications such as data and control wiring, power distribution, signal processing, and electronic equipment.

Application

72/7VZ terminal blocks provide a termination point for multiple wires, allowing them to be securely connected to each other. Their compact design and low profile make them suitable for confined spaces in tight wiring applications, where they are often used for board-mounting in control panel wiring in automotive, industrial, commercial, telecommunications, and aviation industries. They can also be used in wiring applications that require a combination of crimp connection (for loose wires) and traditional soldering (for solid core wires).

72/7VZ terminal blocks are available in a range of sizes and shapes, including blade, dual-blade, and ribbon configurations, and also in DIN mountable and PCB configurations. They are also available in a variety of colors and insulation types including PVC, Thermoplastic, and Nylon.

Working Principle

The working principle of 72/7VZ terminal blocks is based on the induction method. In this method, the module uses an inductively coupled current to create a secure electrical connection. The current is induced by a coil, usually connected on one side of the module. The other side is connected to a contactor terminal that is connected to the conductors of the wires. This contactor terminal has a spring-loaded clip that slips onto the conductor.

The coil is energized, and this induces a current in the conductor attached to the contactor terminal. This current causes eddy currents to form in the conductor, which creates a resistive hot-spot on the conductor’s surface. This hot-spot creates a secure electrical connection with the contactor terminal, and the spring-loaded clip provides a secure mechanical grip on the conductor. The electrical connection is thus made secure and the multiple wires are connected to each other.

The 72/7VZ terminal blocks are also designed with optional insulation covers that protect against finger contact with the energized parts. The covers are available in various colors and materials, including clear Polycarbonate and ABS plastic, to protect against electrical shocks and provide an additional layer of safety.

Conclusion

72/7VZ terminal blocks are a great solution for tight wiring applications, providing a secure electrical and mechanical connection that can be used in a wide range of industries. The induction method used in the terminal blocks is a reliable and easy to use connection system that requires no soldering or crimping. Their optional insulation covers offer additional safety and are available in various colors and materials.
