Title: Breaker

Description:
BACKGROUND OF THE INVENTION  
      (a) Field of the Invention  
      The present invention is related to a breaker, and more particularly to one containing a corrugated clip pushing against both sides of a compound metal on front to stay in conducted status and the compound metal is deformed then returns to its original corrugation shape to immediately interrupt the power supply in case of abnormally high temperature due to high load.  
      (b) Description of the Prior Art  
      While our life is overwhelmed with various types of home electric appliances, they become a daily necessity. Most of the appliances are equipped with plugs. The plug must be inserted into a power socket to draw the power. For safety concerns and to avoid property loss due to overload, the plug should be pulled out of the socket whenever the appliance is not in use and there are often problems with poor conduction due to that the improper connection between the blades and the socket or hazards resulted from static generated by humidity to the blades when the plug and/or the socket are damaged by yanking the power cord.  
     SUMMARY OF THE INVENTION  
      The primary objective of the present invention is to provide a breaker that allows safe and repeated use. To achieve the purpose, the present invention is comprised of a chamber containing a locking pin connected in series with compound metal plate, separation ring, corrugated clip, insulation ring, S conduction plate, DIP slide block, and multiple electrodes.  
      Another purpose of the present invention is to provide a breaker that allows easy operation. To achieve the purpose, the corrugated chip has its both ends inserted and secures in respective locking slots on both sidewalls in the chamber. A protruding piece is disposed on the chip to be inserted into a dip slide block so to expose the dip side block out of a casing to achieve easy operation of the breaker by taking advantage of the repeated locking feature of the clip.  
      Yea another purpose of the present invention is to provide a breaker that allows highly safe and repeated use of circuit breaking for industrial purposes. To achieve this purpose, two locking blocks are respectively provided on both sides to the front of the compound metal plate in the chamber. The clip pushes into the both sides of the compound metal to hold against both locking blocks to become conducted. The compound metal plate is deformed then return to its original corrugation shape to immediately interrupt the power supply in case of abnormally high temperature due to high load.  
      The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.  
      Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
      The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.  
      Referring to  FIGS. 1, 2 , and  3 , a preferred embodiment of the present invention includes a main unit  1  having a chamber  11 . wherein, a locking pin  2  connects in series a compound metal plate  3 , a separation ring  4 , a corrugates clip  5 , an insulation ring.  6 , an S conduction plate  7 , a dip slide block  8 , and multiple electrodes A, B and C before being integrated and inserted into a casing  9 , the main unit  1  contains a chamber  11 , two locking blocks  113 ,  113 A respectively o both sidewalls in the chamber  11 , and two corresponding locking. slots  115 ,  115 A disposed also on both sidewalls behind their respective locking blocks  113 ,  113 A in the chamber  11 . A through hole  32  is disposed at the center of the compound metal plate  3  to receive insertion by the locking pin  2 . The separation ring  4  relates to a stepped ring. A hole  52  is disposed at the center of the corrugated slip  5  to receive insertion by the inner stepped ring of the separation ring  4 . Both ends of the clip  5  are respectively inserted into and secured by both locking slots  115 , 115 A provided on both sidewalls in the chamber  11 , and a protruding piece  58  extends from the clips  5 . The insulation ring  6  relates to a circular ring. Holes are drilled in the front and the rear of the S conduction plate  7  to respective rivet the locking pin  2  and the electrode A. A channel  85  is drilled at where below the dip slide block  8  to receive insertion of the protruding piece  58  on the clip  5 . Both of the electrodes B and C are disposed at where appropriately in the front of the main unit  1 . The casing  9  related to a hollow box having on its top drilled with a notch  98  for insertion by the main unit  1 .  
      Now referring to  FIGS. 4A, 4B  and  5 A,  5 B, the dip slid block  8  pushes into the compound metal plate  5  for both sides of the compound metal plate  5  to hold against locking blocks  113 , 113 A and to be conducted. In case of abnormal high temperature due to high load, the compound metal plate is deformed and curves before being returning to its original corrugated status to immediate interrupt the power supply, thus to provide its industrial purpose providing circuit breaking functions.  
      It will be understood that each of the elements described above, or two or more together many also find a useful application in other types of methods differing from the type described above.  
      While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in ant way from the spirit of the present invention.
