BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The present invention relates to a status display electric signal plug, and specifically a plug structure used with electric signal connections and possessing external ring components pervious to light that directly display the strength of electric signals.  
           [0003]    2. Description of the Prior Art  
           [0004]    Electric signal plugs are widely used in electric signal connections, such as for linking signal sources with all kinds of electric/electronic equipment so that signal sources can directly supply the needed electric signal to electric/electronic equipment. Therefore it is necessary to confirm electric signal strength levels in order to maintain circuit free flow. Nevertheless, in actual situations where electric signal plugs are applied to connect signal source and electric/electronic equipment, it leads to a situation where the electric signal must take an extremely long transmission route because of the connection of the electric signal plug and signal source by an electric cable, thereby creating problems such as transmission failures to the electric/electronic equipment, breaks in signal transmission, or large amounts of damaged signals due to disturbance, route break malfunction, or signal source malfunction.  
           [0005]    Also, the electric signal transmitted by the electric signal plug is usually related to voltage, current, or frequency changes. For example, the electric signal plug power source types commonly used to provide direct current power source to electric/electronic equipment are totally unable to concisely and immediately display status detection results for voltage or current changes in electric cords. If a voltage meter or current meter must be used to measure electric signals in the electric cord then the electric signal plug must be temporarily disconnected from the electric/electronic equipment and this leads to having to temporarily stop using the equipment as well as inconvenient detecting and inspection steps. Also, there are problems we cannot easily or lightly ignore stemming from voltage deficiency, current deficiency, or even breaks in the line or signal transmission inside the electric cable that leads to other malfunction situations and makes it further impossible to use the naked eye to directly obtain observation results; while having to judge by the situation of end equipment performance makes it even more impossible to immediately understand electric signal transmission malfunction circumstances and greatly affects electric/electronic equipment performance.  
         SUMMARY OF THE INVENTION  
         [0006]    The primary objective of the present invention is to provide a status display electric signal plug possessing an electric signal strength detector and circuit display able to directly and immediately display electric signal strengths.  
           [0007]    Another objective of the present invention is to provide a status display electric signal plug possessing an exterior radiating ring that displays electric signal strength and is able to display the conditions of signal strength detection in a manner observable by the naked eye.  
           [0008]    In order to accomplish the above-described objective, the present electric signal plug invention includes a plug that connects to an electric cable at one end for linking to the electric signal source; the above-described plug can detect and display electric signal strength by connecting a circuit detector equipped with an IC detector and at least one display component to the electric cable, in order to detect and display electric signal strength. Moreover, the plug itself also is enclosed with an internal tube and outer case as well as a light conducting tube installed between the internal tube and outer case with a display ring exposed at its top and a plurality of half-circle shaped indentations at its bottom to avoid contact with the circuit detector display components and welded points, acting to diffuse and guide the flashing light from the display component to the display ring thereby revealing electric signal strength and status through the display ring.  
           [0009]    Structural details and application of the present invention will be made clear by the details in the explanation to follow. At the same time an elaboration of the structure are presented in the detailed description of the preferred embodiments below and preceded by the brief description of the drawings to provide a further understanding of technological content of the invention herein.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0017]    First look at FIG. 1 through  3  and notice that the present electric signal plug invention is displayed as unit  100  in all of the following Figures. However plug  100  shall not be limited in shape or form. The present invention uses a direct power source connection model as an example. Plug  100  includes: a plug  10  utilizing direct current connection model as described above, electric cable  20  to link with the electric signal source. The example made in the present invention is used to supply direct current to equipment that includes an insulation encasement  21  at the end of the electric cable  20 (as shown in FIG. 1, 2,  3 ) to act as a bridge inside the plug  10 .  
         [0018]    Conducting wires  22  and  23  of the above described electric cable  20  pass through the top part of insulation encasement  21  to provide electric signal from said signal source (direct current supply equipment). At the top part of insulation encasement  21  is installed a protruded area  30  acting to fasten circuit detector  40  in place. The shape or form of circuit detector  40  is not limited in form, and in the present invention has a disk design with opening  41  designed in the center to allow it to be fixed within protrusion  30 . Other circuit detector forms and fixation methods shall remain within the scope of the present invention.  
         [0019]    IC detector  42  and a plurality of display components  43  are included on circuit detector  40 . IC detector  42  connects to conductor wires  22  and  23  to test the strength of the electric signal. The scope of signal strength testing includes the testing of components such as voltage, currency, frequency, etc, while display component  43  uses different colored lights to show signal strength. For example the present invention&#39;s direct current model use a green light to show normal voltage and currency and an orange light to show irregular voltage or current. Moreover, different colored light signals can be shown by a single display component  43  or a combination of multiple display components  43 , of which the form of component  43  shall not be limited, while the present invention uses Light Emitting Diode (LED) as a explanation demonstration. The above described circuit detector  40  forms a connection with plug  10  through conductor wires  44  in order to again transfer electric signal to plug  10 .  
         [0020]    The circuit connection process of above described IC detector  42  and display components  43  on circuit detector  40  must be completed by a plurality of soldering points  45 , which are individually located spread out on the top and bottom sides of circuit detector  40 .  
         [0021]    In regard to present invention electric signal plug  100  described above there is included internal tube  50  and outer cover  60  encases plug  10 . Inside on plug  10  is circumferential indentation  11  as well as a plurality of indented clips  51  and protruding clips  52  on internal tube  50 . Indented clips  51  match up with circumferential indentation  11  to fix plug  10  and internal tube  50  into one piece, while outer cover  60  is used to encase part of the insulated area  21  of electric cable  20  and internal tube  50 . Internal tube  50  and plug  10  protrude from outer case  60  and are used to connect to the corresponding socket of electric/electronic equipment (not shown in the accompanying figures).  
         [0022]    The form of conduction tube  70  shall not be limited, and can be made from any light conducting transparent or non-transparent tube component structure, fitting beneath said internal tube  50  and outer case  60 , into which are indentations  71  (see FIG. 8- 9 ) matching up with protruding clips on said internal tube  50 , thereby fixing outer case  60  and internal tube  50  tightly together with light conductor tube  70 . On the top outer border of light conductor tube  70  is installed a display ring  72 , which has a mouth larger than the mouth of light conductor tube  70 , which protrudes out beyond outer case  60 . On the inside of this ring is side  721 , which is covered with reflecting or refracting material.  
         [0023]    Now please correlate with FIG. 4, 5,  6 , and  7  to see half-circle shaped indentations  73  on the bottom of said light conductor tube  70 , which fit around each display component  43  and soldering point  45  located on the circuit detector  40  (see FIG. 4, 5,  6 ), thereby ensuring that the bottom of conductor tube  70  does not touch display components  43  and soldering points  45 . This also allows half-circle shaped indentations  73  to act as concave lenses diffusing and guiding the light rays emitted by display component  43  and transmitting them through light conducting tube  70  to display ring  72  at the top end. During this transmission process the reflecting or refracting material applied to inner ring  721  it causes light to reflect or refract 90 degrees thereby expanding light into the entirety of display ring  72  (see FIG. 7) and displaying such results on the surface of display ring  72  so that such results correlate exactly with the colors flashed by circuit detector  40  when it releases signal source electric signal testing results. Thus by looking at the exterior of signal plug  100  the naked eye can directly observe and identify the strength and condition of the electric signal being transferred inside the plug. Moreover, according to the detailed structure, capability, and operation explanation of the present electric signal plug invention as described above in FIG. 1˜ 7 , we discover the following conclusions about its advantages, practical uses, and valuable industrial applications as follows:  
         [0024]    1. Possesses automatic electric signal strength testing capability through the direct testing of the electric signal by circuit detector  40  and display of the results by display component  43 . By now combining this with the conduction and display of flashing from display component  43  though display ring  72  and conductor tube  70 , the user is now able to clearly observe the strength and condition of the electric signal directly with the human eye and without any need for additional apparatus.  
         [0025]    2. Possesses simple and direct clear display capability results. Through a structure causing flashing from display component  43  to be conducted and displayed through display ring  72  and conductor tube  70 , the user does not need to use additional apparatus to be able to clearly observe the strength and condition of the electric signal directly with the human eye.  
         [0026]    The present invention is an electric signal plug with status display, the essence of which lies in the most streamlined composition of components resulting in the electric signal plug possessing direct electric signal strength and status display capabilities, further making it the only such superior invention with industrial application value.
