Why Do Electrical Terminals Fail in High-Vibration Environments?
Understanding failure mechanisms is essential when selecting terminals for demanding applications.
단자 풀림
Mechanical vibration can gradually reduce the retention force between mating terminals. Even microscopic movement can cause a connector to loosen over time.
As vibration cycles accumulate, terminals may partially disengage, resulting in unstable electrical connections and eventual failure.
Common symptoms include:
간헐적인 신호
Power interruptions
Unexpected equipment shutdowns
유지관리 비용 증가
프레팅 부식
Fretting corrosion is one of the most overlooked causes of terminal failure.
Under vibration, microscopic movement occurs between contact surfaces. This repeated motion wears away protective plating and generates oxide particles.
Consequences include:
접촉 저항 증가
Signal degradation
발열
전도성 감소
Industries such as automotive and aerospace frequently encounter fretting corrosion in high-vibration environments.
Wire Fatigue and Conductor Breakage
Repeated vibration can cause stress concentrations near the crimp area.
시간이 지남에 따라, conductor strands may fracture due to cyclic loading, leading to complete electrical disconnection.
Applications with constant motion, such as heavy equipment and railway systems, are particularly susceptible to this issue.
Contact Resistance Increase
As terminals loosen or corrode, the contact resistance rises.
저항이 높을수록:
과도한 열 발생
Reduced current carrying capacity
Connector damage
조기 시스템 오류
This issue becomes especially critical in electric vehicle battery systems and high-current industrial equipment.
Key Design Features of High-Vibration Resistant Terminals
