Electronic device with a floating electrical connector unit

An electronic device comprising:

• a housing having a side wall formed with an access opening therethrough, said access opening having a first length in a first direction, and a first width in a second direction transverse to said first direction;
• a barrier secured to said housing and extending parallel to said side wall, said barrier being spaced apart from said access opening in a third direction transverse to the first and second directions so as to form a connector mounting space between said barrier and said side wall;
• and
• an electrical connector unit including
• a dielectric terminal holding seat disposed in said housing and having a front portion that projects outwardly of said housing through said access opening, and a rear portion that extends from said front portion in the third direction and that is disposed in said connector mounting space, said front portion of said terminal holding seat having a cross-section smaller than size of said access opening such that said terminal holding seat is movable relative to said housing,
• a contact terminal set mounted in said terminal holding seat and having a cable connecting portion that extends in the third direction through said rear portion of said terminal holding seat, and
• a ribbon cable having a terminal mounting plate mounted on one end thereof, said cable connecting portion of said contact terminal set connecting electrically with said ribbon cable and being mounted on said terminal mounting plate, said terminal mounting plate being disposed in said connector mounting space and having an abutment face in sliding contact with a contact face of said barrier.
