Vacuum cleaner

Abstract

A vacuum cleaner having a suction brush; a cleaner body detachably mounted on an upper portion of the suction brush and having a suction fan for generating a suction force and a dust receptacle for collecting dust therein; and first and second cable units mounted in the suction brush and the cleaner body, respectively. The first and the second cable units are connected so that electricity is applied to the suction brush when the vacuum cleaner is used with the cleaner body mounted on the upper portion of the suction brush, and disconnected so that the electricity is shut off with respect to the suction brush when only the cleaner body is used, being separated from the suction brush.

1 . A vacuum cleaner comprising: 
 a suction brush;    a cleaner body detachably mounted on an upper portion of the suction brush and having a suction fan for generating a suction force and a dust receptacle for collecting dust therein; and    first and second cable units mounted in the suction brush and the cleaner body, respectively,    wherein the first and the second cable units are connected so that electricity is applied to the suction brush when the vacuum cleaner is used with the cleaner body mounted on the upper portion of the suction brush, and disconnected so that the electricity is shut off with respect to the suction brush when only the cleaner body is used, being separated from the suction brush, and    the first cable unit comprises, 
 a plurality of plug pins connected with an electric wire,  
 a pin housing having a plurality of connection grooves distanced from one another for insertion of the plug pins, and  
 a plug supporter fixing the plug pins at the rear side of the plug pins.  
   
   
   
       2 . The vacuum cleaner of  claim 1 , wherein the plug pins are configured in a manner that a first portion mounted in the pin housing has a larger diameter than a second portion exposed to the outside of the pin housing.  
   
   
       3 . The vacuum cleaner of  claim 2 , wherein the connection groove includes a support part which supports a stepped portion formed on an outer circumference of the plug pin.  
   
   
       4 . The vacuum cleaner of  claim 3 , wherein the first cable unit, in which the plug pin, the pin housing and the plug supporter are assembled, comprises an exterior of molded polyvinyl chloride (PVC).  
   
   
       5 . The vacuum cleaner of clam  1 , wherein the second cable unit comprises: 
 a plurality of pin sockets receiving the plurality of plug pins;    an outlet cover supporting one end of each of the plurality of pin sockets; and    a pin socket housing supporting another end of each of the plurality of pin sockets.    
   
   
       6 . The vacuum cleaner of  claim 5 , wherein the outlet cover comprises a plurality of hollow depressions for receiving and fixing the plurality of pin sockets.  
   
   
       7 . The vacuum cleaner of  claim 6 , wherein the plurality of plug pins comprises three plug pins and the plurality of pin sockets comprises three pin sockets, wherein said three plug pins and said three pin sockets are provided to supply 3-phase induced electricity.  
   
   
       8 . A vacuum cleaner comprising: 
 a suction brush;    a cleaner body detachably mounted to said suction brush;    a first cable unit having a pin housing around a plug pin, said plug pin being in electrical communication with a first electric wire at a first connection point, said plug pin having a first portion extending from a via hole of said pin housing and a stepped portion in said pin housing; and    a second cable unit having an outlet cover around a pin socket, said pin socket being in electrical communication with a second electric wire at a second connection point, said outlet cover having an end through which said second electric wire is defined,    wherein said plug pin and said pin socket are connected so that said first and second wires are in electrical communication when said cleaner body is mounted to said suction brush and are separated so that so that said first and second wires are not in electrical communication when said cleaner body is separated from said suction brush, and    wherein said stepped portion of said plug pin is prevented from being withdrawn from said pin housing through said via hole so that no load is applied to said first connection point when connecting and separating said plug pin and said pin socket.    
   
   
       9 . The vacuum cleaner of clam  8 , wherein said end of said outlet cover has a smaller diameter than an outer diameter of said pin socket so that no load is applied to said second connection point when connecting and separating said plug pin and said pin socket.  
   
   
       10 . The vacuum cleaner of clam  9 , wherein said first cable unit comprises three of said plug pins and said second cable unit comprises three of said pin sockets.
