Product Overview
The model of N male plug crimp connector is N-C-J400-1.N series are very popular screw-coupling middle-or-low power coaxial connectors with impedances of 50Ω and 75Ω. They are widely used for electrical instruments or applications where vibration resistance and environmental protection is required, including communication equipment, coaxial components,duplexers, couplers, microwave testing system and microwave network or connecting RF cables. Connected with high accuracy semi-flexible or semi-rigid cables N connectors can work up to11GHz resulting in low VSWR.

As a type of threaded connection, the N-type connector boasts high reliability, excellent shielding, and is widely used. However, due to the wide range of uses for threaded connectors, connection failures are common. Below, we'll summarize these issues and briefly explain how to address them.
Connection failed
1. The designer made an inappropriate material selection. To reduce costs, they mistakenly used a non-elastic brass seat ring, which easily caused the nut to fall off.
2. During processing, the groove for the nut retaining ring was not deep enough, causing the nut to fall off even with a slight application of torque during connection.
3. Although the material selection was correct, the process was unstable. The beryllium bronze elastic treatment did not reach the hardness specified in the drawings, resulting in a lack of elasticity in the retaining ring, which caused the nut to fall off.
4. During testing, the user did not have a torque wrench and used a standard wrench to tighten the nut. The tightening torque greatly exceeded the specified value, causing the nut (retaining ring) to become damaged and fall off.
