Patent ID: 7442088

Claim:
A system for ensuring proper circuit board assembly insertion, comprising: a circuit board assembly including (i) a first keying feature coupled to or integral with the circuit board assembly at a location other than at a faceplate and (ii) a first component of a connector assembly; and a support assembly configured to receive the circuit board assembly and including (i) a second component of the connector assembly and (ii) a second keying feature coupled to the support assembly at a location offset in a direction relative to the second component toward the first component as the first component travels toward the second component to mate with the second component that (a) allows the circuit board assembly to be inserted into the supporting assembly to mate the first and second components of the connector assembly if the first keying feature is aligned with the second keying feature and (b) prevents contact between the first and second components of the connector assembly if the circuit board assembly lacks the first keying feature or has the first keying feature but is not aligned with the second keying feature.
