Description:
BACKGROUND OF THE INVENTION 
     1) Field of the Invention 
     The invention herein relates to a signal cable connector comprised of a lower housing, an upper housing, four fan-shaped levers, two squeeze buttons, a connector shell, a signal cable, a plastic body, and a fastening component, the structural innovations of which include the profiling of gear teeth on the fan-shaped levers that minimize physical effort during connector removal and, furthermore, that are simultaneously articulated into convergence to automatically dislodge the signal cable connector from equipment panels. 
     2) Description of the Prior Art 
     Conventional signal cable connectors are utilized to establish continuity between the connectors of household audio-video equipment, with the said signal cable connectors having 20 built-in contacts to conduct signals of varying frequencies and formats such as the audio, composite video, S-VHS (super VHS) video, and component video signals widely used by household audiovisual appliances. Since the conventional signal cable connectors linking household audio-video equipment are typically extended length conductor interfaces and, furthermore, have a high number of contacts, when the said signal cable connectors are plugged into or unplugged from equipment, the frictional resistance encountered is of considerable magnitude and even requires rocking to the left and right before manual force is sufficient to achieve removal; however, such procedures often result in the serious shortcomings of shape deformity and poor contact. 
     In view of the existent technological drawbacks of conventional product structures, the inventor of the invention herein originated several innovations based on professional knowledge and extensive design experience gained while engaged in the related fields that culminated in the successful design of the improved structure signal cable connector of the present invention. 
     SUMMARY OF THE INVENTION 
     The objective of the invention herein is to provide a signal cable connector, the structural innovations of which include the profiling of gear teeth on four fan-shaped levers to minimize physical effort during removal and, furthermore, that are simultaneously articulated into convergence to automatically dislodge the signal cable connector from equipment panels, a feature that effectively enhances the practical value of signal cable connectors.

     The connector shell  81  is a hood-like structure of punch-fabricated metal construction and a plurality of connector pins arrayed in two rows are disposed along the interior section of the connector shell  81 ; a signal cable  82  consists of numerous individual wires and is soldered to the rear section of the said connector shell  81 ; and the plastic body  8  is an injection molded enclosure situated between the connector shell  81  and the signal cable  82 . The lower housing  1  and the upper housing  5  constituting its top and bottom sides, respectively, are aligned together and, furthermore, two screws  59  are respectively inserted into the screw holes  51  and  52  of the upper housing  5  and then fastened to the tapped mounting posts  11  and  12  of the lower housing  1 ; the squeeze button  4  has a screw hole  41  formed in each of its two sides, and two screws  42  are respectively inserted through the union shank  21  and  61  holes  22  and  62  of the fan-shaped levers  2  and  6  and fastened therein; the other squeeze button  43  has a screw hole  44  formed in each of its two sides, two screws  45  are respectively inserted through the union shank  3  and  7  holes  32  and  72  of the fan-shaped levers  3  and  7  and fastened therein; furthermore, the said fastening component  9  is installed onto the external threads  18  and  58  at the top edges and rear sides of the lower housing  1  and the upper housing  5  to complete the assembly of the signal cable connector of the present invention. 
     Given the assembled structural components of the invention herein, referring to FIG.  3  and FIG. 4, the said signal cable connector is plugged into the female socket of audio-video equipment A and the fan-shaped lever union shanks  61 ,  21 ,  71 , and  31  extend outward and, furthermore, are postured in a perpendicular state; when the user wants to unplug the signal cable connector, the user only has to press the squeeze buttons  4  and  43  together, at which time the said four fan-shaped levers  2 ,  3 ,  6 , and  7  simultaneously converge inward such that their lifting lobes  24 ,  34 ,  64 , and  74  situated against the panel of the audio-video equipment A automatically dislodges the signal cable connector in an effort-saving and stable operation; when the squeeze buttons  4  and  43  are released, the four fan-shaped levers  2 ,  3 ,  6 , and  7  of the present invention are restored back to their original perpendicular state by the wound springs at their back sides. 
     In summation of the foregoing section, since the disclosed structure of the invention herein is capable of achieving the claimed objectives and is of greater practical value and functionality, the invention herein is submitted to the examination committee for review in application for the granting of the commensurate patent rights.
