Sealed cavity with vent hole method and apparatus for use in sensor modules

摘要

A method and apparatus for creating a sealed cavity includes a housing assembly (100) incorporating a molded connector (110) with an interior portion formed into a cavity (170) and a vent hole (160) that communicates with the cavity (170). The vent hole (160) permits escape of gas generated by solidification of sealant (410) used to attach lid (410) to housing lid seat (120). The vent hole (160) further prevents contaminants from reaching the cavity interior until the final connector seal is applied. The vent hole (160) can be interfaced with a final applied mating sealed connector which utilizes the mating connector seal to provide the final cavity seal. The molded connector (110) can then be adapted with a sensor module which circumvents the need for sealing the small vent hole (160) using additional processes.
