Full Description:
FIELD OF THE INVENTION 
   The present invention generally relates to an electronic assembly, and more particularly to an electronic assembly with a foldable connector thereof. The invention relates to the copending application having the same title, the same filing date, the same applicants and the same assignee therewith. 
   DESCRIPTION OF PRIOR ART 
   As development of an electronic technique, an electronic device becomes lower profile and multifunction. Some consumer products, especially those video/audio products, should be equipped with a lower profile power port and signal port. For example, U.S. Pat. Nos. 6,461,198, 6,038,766, 5,895,294 and TW Pat. 406884 introduce some related art of electrical connectors. 
   U.S. Pat. No. 6,461,198 (hereinafter refer to U.S. &#39;198) discloses audio connection apparatus. The connection apparatus includes plug and jack assemblies. The jack assembly defines a primary insertion hole and at least a pair of secondary insertion openings disposed laterally therefrom. The jack assembly includes a plurality of first conductive plates disposed in each of the secondary insertion openings. The plug assembly which releasably couples to the jack assembly includes a central shaft for engaging the primary insertion hole of the jack assembly in electrically conductive manner, as well as at least a pair of secondary insertions disposed laterally from the central shaft for respectively engaging the insertion openings of the jack assembly in electrically conductive manner. Each secondary insertion includes a plurality of second conductive plates each configured to contact a first conductive plate in electrically conductive manner. The engagement of the secondary insertions and secondary insertion openings enables the auxiliary transmission of electrical audio signals for supplementing the transmission of electrical audio signals through the engagement of the central shaft and primary insertion hole. 
   However, the plug assembly of U.S. &#39;198 may be disposed outside of an electronic device, and it may occupy more space and be damaged by exterior environmental conditionals. 
   Hence, an improved electrical assembly is highly desired to overcome the aforementioned problems.

   Referring to the  FIGS. 1-2  and  6 - 9 , the spring member  54  is capable of biasing or preloading a force to the rotational member  5  and thus plug connector  53  is exposed outside of the housing and perpendicular thereto. When the electronic device  100  is retracted into the housing, an exterior force exerted onto the base portions  51 ,  52 , and the rotational member  5  pivots around the shaft  151 , and the plug connector  53  presses onto the inclined surface  621  of the wedge shaped free end  623  to make the resilient member  61  compressed, and a free end of the plug connector  53  slides excessively inwardly and disposed behind the stopper portion  62 , thus the plug connector  53  is locked by the stopper portion  62 . When the plug connector  53  is used, just push the bar portion  64  moving laterally to make the free end  623  of the stopper portion  62  away from the plug connector  53 , thus the plug connector  53  is exposed outside of the housing via a restore force by the spring member  54 . 
   It will be understood that the invention may be embodied in other specific forms without departing from the spirit or central characteristics thereof. The present examples and embodiments, therefore, are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the details given herein.
