Causes of Pogo Pin breakage
PogoPin covers various springs and connectors such as charging pins, battery pins, antenna pins, etc. This connector has the advantages of small size, large current, strong contacts, beautiful appearance, and stable performance. It is widely used in mobile phones, walkie-talkies, and connections. Line, digital products, laptop computers, security products, medical equipment, aerospace, military electronics, communication equipment, consumer electronics, household appliances, toys, etc.
The stresses received by the spring mainly include bending stress, changing stress, tension and compression stress, and compound stress.
The main faults of the spring are cracking, deformation, slack, and abrasion. The main analysis is cracking and deformation (relaxation).
1. Brittle cracking: most of the spring cracks are brittle cracking. Only when the working temperature is relatively high, will some of them show plastic cracking. In engineering, fatigue cracking, stress corrosion cracking, and hydrogen embrittlement cracking are all called brittle cracking.
2. Fatigue cracking: cracking of the spring under the effect of cyclic loading.
3. Stress corrosion cracking: Tension spring cracking is caused by the action of tensile stress and corrosive media.
4. Corrosion fatigue cracking: the spring cracking under the action of cyclic load and corrosive medium.
5. Hydrogen embrittlement, cadmium embrittlement, black embrittlement: brittle fracture caused by high impurity content in the spring material.
6. Wear: Wear is divided into abrasive, fatigue and corrosion wear, and cracking.
