What ensures that all contacts align properly during a visual inspection on the connector?

• A. Latching mechanism
• B. Dielectric
• C. Keyways
• D. Shielding

Answer: (C)

Keyways provide the orientation guide that makes sure every contact lines up in its proper position when the connector is mated. The mating halves are designed with matching grooves and ridges so they can only fit together in one correct orientation, guiding each contact into its intended place. During a visual inspection, this alignment becomes apparent as the contacts sit in their proper channels and the plug and receptacle mate cleanly. The latching mechanism simply secures the connection after correct alignment; it doesn’t ensure that alignment by itself. Dielectric is the insulating material around the contacts, and shielding is the EMI/RFI protection around the assembly. So the feature that ensures proper contact alignment is the keyways.
