Claim Text:
1. A connecting unit adapted to be mounted to a housing of an electronic device for connecting an electronic unit to the housing, the housing having an inner surface, the electronic unit including a board body that has one side facing the inner surface, and that is formed with a first through hole, said connecting unit comprising: a first connecting component adapted to be mounted to and in the housing, projecting from the inner surface of the housing, and having an end face that is distal from the inner surface and that is formed with a fastening hole; a second connecting component including a head and a stem that is connected to said head, that has a cross-section smaller than that of said head, and that cooperates with said fastening hole in said first connecting component; and a buffering member sleeved on said first connecting component, being resilient, and having an end that is adapted to abut against the board body and that is formed with a mounting hole registered with said fastening hole in said first connecting component, a portion of said buffering member being disposed between said first connecting component and the board body; wherein said stem of said second connecting component extends through the first through hole and said mounting hole to engage said fastening hole so as to secure said second connecting component to said first connecting component, such that the board body of the electronic unit abuts against said buffering member, and is spaced apart from said first connecting component and said head of said second connecting component so as to be movably restricted relative to the housing between said head of said second connecting component and said buffering member; wherein said buffering member includes a surrounding wall surrounding said first connecting component, and a top wall extending from said surrounding wall to abut against said end face of said first connecting component, and has a bottom face abutting against said inner surface, said top wall having a top face opposite to said bottom face and adapted to abut against the board body, said mounting hole being formed in said top wall; and wherein said top wall of said buffering member further includes a plurality of spaced-apart top abutting blocks which surround said mounting hole and cooperatively forming said top face so as to increase resiliency in the portion of said buffering member that is in contact with the board body.
