Description




BACKGROUND OF THE INVENTION




This invention relates to a coupling structure for mobile video device, particularly to a coupling structure for mobile video device provided with multiple output terminals and a commensurable multi-terminal jack for easy installation and maintenance and a multistage adjustment device for multistage adjustment.




Subsequent to the soaring popularity of the personal mobile video device, convenience of maintenance job is considered more important than ever, however, as the wiring in a conventional mobile video device is usually coupled in way of point or cup joint, it would be rather troublesome to open the seat for wire-cutting and wire-connecting when maintaining.




In a coupling structure for the conventional mobile video device shown in

FIG. 1

, a video device C is disposed in a pillow A, wherein a plurality of signal transmission lines C


1


penetrates through a branch pipe A


1


of the video device C, then is sleeve-jointed with an adopter C


2


which is coupled to a signal transmission line D extended out of a seat B; and another branch pipe A


1


is swiveled to lock on a pipe end A


2


.




In view of abovesaid imperfection in maintenance, after years of constant effort in research, the inventor of this invention has consequently developed and proposed an improved coupling structure pertaining to the subject matter.




SUMMARY OF THE INVENTION




This invention is proposed to provide a coupling structure for mobile video device with multiple output terminals and a commensurable multi-terminal jack for easy installation and maintenance and a multistage adjustment device for multistage adjustment.




For a better understanding to the present invention, together with further advantages or features thereof, at least one preferred embodiment will be elucidated below with reference to the annexed drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




As shown in

FIG. 2

, a mobile video device


3


is included in a pillow


1


, wherein a signal transmission line


31


penetrated through a branch pipe


11


is coupled with a signal terminal


32


located at one end of the branch pipe


11


. A pair of the branch pipes


11


of the pillow


1


is plugged in two insertion holes


21


of a seat portion


2


and snap-fastened to a pair of terminal jacks


41


of an adjustment device


4


. The mobile video device


3


is movable up and down along a pair of displacement rails


43


in virtue of a displacement block


42


. At an upper and a lower end of the adjustment device


4


, an upper and a lower stopper


44


,


45


are disposed respectively for easy dismounting or mounting of the mobile video device


3


. And, an exit hole


416


is perforated at a bottom end of the terminal jack


41


for extending a signal transmission line


46


.




Referring to FIG.


3


A through FIG.


3


C and FIG.


4


A through

FIG. 4D

, a plurality of signal contact points


321


is offered to each of the signal terminals


32


according to requirement of the increasing functions of the mobile video device


3


. The signal terminal


32


is lengthened in a multi-layer structure for accommodating the contact points


321


, which may be aligned horizontally or staggeringly, and a plurality of receptacles or slots


322


is also arranged in the signal terminal


32


. A positioning groove


323


is formed in the signal terminal


32


, and a positioning piece


111


is disposed on the branch pipes


11


to facilitate wiring of the signal terminal


32


correctly and prevent the signal terminal


32


from causing a short circuit because of improper swiveling, and one or two sets of the signal terminal


32


may be arranged depending on functions provided by the mobile video device


3


.




As shown in

FIGS. 5A and 5B

, a plurality of storage receptacles


412


is formed in the inner wall of the terminal jack


41


, wherein an elastomer


413


and a steel bead


414


are buried in the storage receptacle


412


in sequence. A plurality of positioning dimples


322


is formed on the signal terminal


32


at positions corresponding with the storage receptacles


412


of the terminal jack


41


. Therefore, the steel bead


414


of the terminal jack


41


is pushed by the elastomer


413


into the positioning dimple


322


of the signal terminal


32


when the terminal


32


is plugged to joint with the terminal jack


41


, and thereby a short circuit owing to improper swivel of the signal terminal


32


can be avoided. At this moment, the signal contact point


321


of the signal terminal


32


is in conductive contact with a signal contact point


411


of the terminal jack


41


.




In another way of coupling the signal terminal


32


with the terminal jack


41


, a plurality of elastic pieces


415


is disposed in the inner wall of the terminal jack


41


and a plurality of positioning dimples


322


on the signal terminal


32


at positions corresponding with the elastic pieces


415


. Hence, the elastic piece


415


is snap-retained in the positioning dimple


322


when the signal terminal


32


is plugged to joint with the terminal jack


41


. At this moment, the signal contact point


321


of the signal terminal


32


is in conductive contact with the signal contact point


411


of the terminal jack


41


.




In

FIG. 6

, after the signal terminals


32


have been snap-retained in the terminal jacks


41


of the adjustment device


4


, the mobile video device


3


is movable up and down along the displacement rails


43


by virtue of the displacement block


42


. As abovesaid, at the upper and the lower end of the adjustment device


4


, the upper and the lower stopper


44


,


45


are disposed respectively for easy dismounting or mounting of the mobile video device


3


, and the exit hole


416


is perforated at the bottom end of the terminal jack


41


for extending the signal transmission line


46


. Further, a plurality of positioning dimples


421


is disposed at two lateral lines properly in the displacement block


42


while a plurality of storage receptacles


431


is formed in those two displacement rails


43


, wherein an elastomer


432


and a steel bead


433


are buried in each storage receptacle


431


sequentially. Hence, the height of the pillow


1


of the mobile video device can be adjusted as desired.




In short, this invention is proposed to provide a coupling structure that is more advantageous for installing and maintaining a mobile video device, and an additional multistage that is convenient for adjusting height of the pillow of the mobile video device.




In the above described, at least one preferred embodiment has been elucidated with reference to drawings annexed, it is apparent that numerous variations or modifications may be made without departing from the true spirit and scope thereof, as set forth in the following claims.
