Clamping tool for connecting coaxial cable and terminal

Abstract

This invention relates to a clamping tool for connecting coaxial cable and terminal, the clamping tool being composed of a connecting frame, two clamping handles, four connecting links, a sliding seat and a guiding tube. One end of the clamping handle being pivoted on the connecting frame, two end of the connecting link being pivot respectively on the clamping handle and the connecting frame, the sliding seat being fixed on the ellipse hole of the connecting frame and one pivot end of the connecting links, the guiding tube being inserted through a clamping head and fixed on the sliding seat. Once the operator press the clamping handles inwardly, the connecting links will move along the ellipse holes to push the sliding seat and the clamping head upwardly to clamp the terminal until it is connected with a coaxial cable, further, the central conductor of coaxial cable can be inserted into the guiding tube and kept on the straight to prevent it from being twisted in clamping process.

1 . A clamping tool for connecting coaxial cable and terminal comprising: 
 a connecting frame, top of the connecting frame having an aperture and two upright part, two sides of the connecting frame having respectively two parallel ellipse holes, two sides of each upright part having respectively a pivot hole;    two clamping handles, one end of the clamping handle being pivoted on said pivoting hole, two sides of the clamping handle having respectively a connecting hole;    four connecting links, one end of the connecting link being pivoted on said connecting hole and the other end being pivoted on said ellipse hole;    a sliding seat fixed on said ellipse holes and said other end of the four connecting links, top and bottom of the sliding seat having respectively a screw hole and an opposite locating hole;    a clamping head screwed into said screw hole, the clamping head having a central hole;    a guiding tube having a guiding hole, one end of the guiding tube being inserted through said central hole of the clamping head and fixed on said locating hole, the central conductor of coaxial cable can be inserted into the guiding hole, once pressing the clamping handles inwardly, said four connecting links can move along said ellipse holes to push said sliding seat and said clamping head upwardly to clamp the terminal until it is connected with the coaxial cable, further, the central conductor of coaxial cable can be kept on the straight to prevent it from being twisted in clamping process.    
   
   
       2 . A clamping tool for connecting coaxial cable and terminal as claimed in  claim 1 , wherein the top of each said upright part having respectively a clip piece, the clip piece being pivoted respectively on said pivot hole and can be moved toward to each other when pressing said clamping handles inwardly, the near end of the two clip pieces having respectively a semicircular aperture which can form a circular aperture to clip the coaxial cable and press the top of terminal in clamping process.  
   
   
       3 . A clamping tool for connecting coaxial cable and terminal as claimed in  claim 1 , between said screw hole and said locating hole have a tension spring which is installed on outside of said guiding tube so as to diminish excessive clamping force to prevent the central conductor of coaxial cable from being twisted in clamping process.
