Constant frequency power supply

Abstract

A constant frequency power supply applied in an exchange-type circuit having a primary winding and a secondary winding includes a first core, a second core, a first bobbin, and a second bobbin. The first core and the second core being disposed in opposite position have a first protruded body and a second protruded body respectively. The first bobbin being positioned on the first protruded body and having a first set of coils wound around thereof is electrically connected to a first set of connecting pins of the primary winding The second bobbin being positioned on the second protruded body and having a second set of coils wound around thereof is electrically connected to the second set of connecting pins of the secondary winding. The first bobbin further includes a slip opening that is capable of slipping on the second bobbin. A sliding telescopic combination is formed by making use of the slipping opening to perform displacement motion on the first protruded body and the second protruded body in order to perform the action of adjusting the inductance between the primary winding and the secondary winding.

1 . A constant frequency power supply applied in an exchange-type circuit having a primary winding and a secondary winding comprising: 
 a first core and a second core being disposed in opposite position and having a first protruded body and a second protruded body;    a first bobbin being positioned on the first protruded body and having a first set of coils wound thereof, and being electrically connected to a first set of connecting pins of the primary winding: and    a second bobbin being positioned on the second protruded body and having a second set of coils wound thereof, and being electrically connected to a second set of connecting pins of the secondary winding;    wherein the first bobbin further includes a slip opening that is capable of slipping on the second bobbin, and a sliding telescopic combination is formed by combining the first bobbin and the second bobbin, together with the slipping opening to perform displacement motion on the first protruded body and the second protruded body in order to perform the action of adjusting the inductance between the primary winding and the secondary winding.    
   
   
       2 . The constant frequency power supply applied in an exchange-type circuit having a primary winding and a secondary winding as claimed in  claim 1 , wherein the first bobbin and the second bobbin have at least a partition plates and a wire slot partitioned by the partition plates respectively.  
   
   
       3 . The constant frequency power supply applied in an exchange-type circuit having a primary winding and a secondary winding as claimed in  claim 1 , wherein the slip opening has an inside diameter that is greater than the outside diameter of the second bobbin.  
   
   
       4 . The constant frequency power supply applied in an exchange-type circuit having a primary winding and a secondary winding as claimed in  claim 1 , wherein the primary winding and the secondary winding are separated at a distance.  
   
   
       5 . The constant frequency power supply applied in an exchange-type circuit having a primary winding and a secondary winding as claimed in  claim 1 , wherein the first bobbin is capable of performing a displacement motion along the extended direction of the first protruded body.  
   
   
       6 . The constant frequency power supply applied in an exchange-type circuit having a primary winding and a secondary winding as claimed in  claim 1 , wherein the second bobbin is capable of performing a displacement motion along the extended direction of the second protruded body.  
   
   
       7 . The constant frequency power supply applied in an exchange-type circuit having a primary winding and a secondary winding as claimed in  claim 1 , wherein the first protruded body and the second protruded body are arranged in a predetermined shape.
