Ring connectors are a type of electrical terminal that is composed of two or more screws and a ring collar to provide a threaded termination connection point for insulated cables. The PN18-4R-3K ring connector is a popular choice for a wide variety of applications in industries such as industrial machinery, transportation, and communications. In this article, we will explore the features, applications, and working principle of the PN18-4R-3K ring connector.

Features

The PN18-4R-3K ring connector has a number of features that make it a popular choice for many applications. It is made of high-conductivity cold-rolled steel that has been zinc-plated to resist corrosion. The screw terminals are angled to promote easy wiring and specialized designs help to reduce crosstalk interference and vibration. The spring-type terminals allow for neat wiring by holding the wires firmly in place and the double-sided zinc alloy die-cast cage helps to uniformly distribute the pressure of the terminals. The PN18-4R-3K is a RoHS-compliant, UL-approved connector and is available in a variety of sizes and colors to meet any application needs.

Application Field

The PN18-4R-3K is used in a variety of applications due to its versatile design. It is commonly found in electrical installations for industrial machinery, control systems, instrumentation systems, and telecommunications. It is also used in railway, automotive, metro and traction traction systems, fuel cell power plants, LED lighting, and electronic products. In addition, the PN18-4R-3K can be used for air conditioning, refrigeration, and air relay apparatus.

Working Principle

The PN18-4R-3K is a two-way terminal with three elements: the nut, the washer, and the spring. The outer nut is tightened to provide a secure bond between the wire and the terminal. The washer is then placed between the conductor and the spring to prevent shorts. The spring is placed under the conductor to ensure a clean and secure connection. Once the nut, washer, and spring are in place, a tightening torque is applied to make a permanent connection with the inner conductor.

In order for a PN18-4R-3K connection to be completed, the nut must be tightened until the threading has reached a certain level and the washer must be securely in place. Once tightened, the washer should be covered by the spring, which should be firmly against the terminal and firmly against the cable. The PN18-4R-3K connection then forms a uniform and strong connection that will not loosen over time.

Conclusion

The PN18-4R-3K ring connector is a versatile, reliable terminal choice for a variety of applications. Its features, such as its corrosion-resistant zinc-plated steel construction and specialized designs, make it a popular choice for use in industries such as industrial machinery, transportation, and communications. Its three-part assembly, with a nut, washer, and spring, make for a secure and reliable connection when screwed down correctly. With these characteristics, the PN18-4R-3K is an ideal ring connector for many applications.
