  • Patent number: 7758353
    Abstract: A circuit board connector assembly mounted in a housing and method of mounting are described. The assembly has orthogonal first and second circuit boards (CB). The CB has a CB connector containing a CB housing with CB electrical contacts. A flexible electrical link has a link connector mounted in a link connector housing with link electrical contacts. A resilient pad is mounted on a link connector housing and a flexible sheet is mounted to both the pad and the link. The sheet spans a length of the link. When the length of the link is substantially planar, the sheet provides a ramp tapering away from the pad. During mounting of the assembly in the housing, the CB connector is operatively coupled to the link connector thereby forming a first connector assembly, and an abutment edge of the second circuit board slidably engages the sheet thereby compressing the pad.

  • Patent number: 7484981
    Abstract: A submersible electrical connector assembly (300) includes an electrical connector (301) mounted to a first substrate (309) where a second substrate (311) adjoins the first substrate (309). The second substrate (311) is comprised of a pliable material that acts as a seal. The first substrate and second substrate are positioned within a compartmentalized area of an electrical device housing for preventing water or other fluid from entering an aperture within the housing. Although water may inadvertently enter the electrical connector (301), the connector assembly (300) is substantially submersible since water is prevented from entering the housing (400) as used for an electronic device.
