What must be undamaged during a visual inspection on the connector?

• A. Conductive material
• B. Dielectric
• C. Ground plane
• D. Shielding

Answer: (B)

The insulating dielectric between the connector’s conductors must remain undamaged. This dielectric insulates the conducting paths and defines the connector’s voltage isolation. If the dielectric is cracked, chipped, swollen, or shows moisture intrusion, it can create leakage paths, lead to arcing between contacts, and cause insulation breakdown or changes in impedance. These issues can result in electrical faults or reliability problems, which is why visual inspection focuses on the integrity of the dielectric. The other elements—conductive material, shielding, and ground plane—are important for function and EMI control, but the condition of the dielectric is the critical factor to verify in a visual check.
