Abstract

A coupling structure for mobile video device provided with multiple output signal terminals and a pair of commensurable multi-terminal jacks for easy and rapid installation or maintenance, and with a multistage adjustment device for adjusting the mobile video device in multiple steps.

Claims

1. A coupling structure for a mobile video device having a mobile video device buried in a pillow, the structure comprising a plurality of signal transmission lines of said mobile video device penetrating through a branch pipe of said pillow and coupled with a signal terminal at a bottom end of said branch pipe, said pillow is coupled with a seat portion by a pair of said branch pipes plugged in two insertion holes of said seat portion for being snap-retained in a pair of terminal jacks of an adjustment device so that the video signal can be transmitted as expected, and

wherein said signal terminal is coupled with said terminal jack by a plurality of storage receptacles in the inner wall of said terminal jack, an elastomer and a steel bead are buried in said storage receptacle in sequence, a plurality of positioning dimples are formed on said signal terminal at positions corresponding with said storage receptacles of said terminal jack so that the steel bead of said terminal jack is pushed by said elastomer into said positioning dimple of said signal terminal, and thereby a signal contact point of said signal terminal is in conductive contact with a signal contact point of said terminal jack.

2. A coupling structure for a mobile video device having a mobile video device buried in a pillow, the structure comprising a plurality of signal transmission lines of said mobile video device penetrating through a branch pipe of said pillow and coupled with a signal terminal at a bottom end of said branch pipe, said pillow is coupled with a seat portion by a pair of said branch pipes plugged in two insertion holes of said seat portion for being snap-retained in a pair of terminal jacks of an adjustment device so that the video signal can be transmitted as expected, and

wherein a plurality of elastic pieces are disposed in the inner wall of said terminal jack and a plurality of positioning dimples are formed on said signal terminal at positions corresponding with the elastic pieces, each elastic piece is snap-retained in a positioning dimple when said signal terminal is plugged to join with said terminal jack, and the signal contact point of said signal terminal is in conductive contact with the signal contact point of said terminal jack.

3. A coupling structure for a mobile video device having a mobile video device buried in a pillow, the structure comprising a plurality of signal transmission lines of said mobile video device penetrating through a branch pipe of said pillow and coupled with a signal terminal at a bottom end of said branch pipe, said pillow is coupled with a seat portion by a pair of said branch pipes plugged in two insertion holes of said seat portion for being snap-retained in a pair of terminal jacks of an adjustment device so that the video signal can be transmitted as expected, and

wherein a positioning groove is formed in said signal terminal, and a positioning piece is disposed on said branch pipes to facilitate wiring of said signal terminal correctly in order to prevent said signal terminal from causing a short circuit because of improper swiveling.

4. A coupling structure for a mobile video device having a mobile video device buried in a pillow, the structure comprising a plurality of signal transmission lines of said mobile video device penetrating through a branch pipe of said pillow and coupled with a signal terminal at a bottom end of said branch pipe, said pillow is coupled with a seat portion by a pair of said branch pipes plugged in two insertion holes of said seat portion for being snap-retained in a pair of terminal jacks of an adjustment device so that the video signal can be transmitted as expected, and

wherein said mobile video device is movable up and down along a pair of displacement rails by a displacement block after said signal terminals have been snap-retained in said terminal jacks of said adjustment device, at an upper end and a lower end of said adjustment device, an upper and a lower stopper are respectively disposed for easy dismounting or mounting of said mobile video device, a plurality of positioning dimples are disposed at two lateral lines in said displacement block while a plurality of storage receptacles are formed in the pair of displacement rails, an elastomer and a steel bead are buried in each storage receptacle sequentially, and by this architecture, the height of said pillow including said mobile video device can be adjusted as desired, and an exit hole is perforated at a bottom end of said terminal jack for extending a signal transmission line.
