  • Patent number: 7670170
    Abstract: A connector assembly includes a first connector having a housing and a plurality of contacts extending from the housing. The housing and the contacts define a mating interface and the first connector includes a light source. A second connector has a housing and a plurality of contacts defining a mating interface configured to mate with the mating interface of the first connector. The connector assembly also includes a light pipe assembly having a plurality of separate light pipe segments, wherein a first light pipe segment is provided with the first connector and directs light from the light source, and a second light pipe segment is provided with the second connector and receives light from the first light pipe segment to direct light to an external portion of the second connector.
