  • Patent number: 11043782
    Abstract: An adjustable coaxial cable compression tool, terminating a coaxial cable connector onto a coaxial cable end, comprising a plunger, a body, a fixed guideway plate, a first moveable guideway plate, a second moveable guideway plate, and a die block is provided. The plunger comprises a first plunger head and a second plunger head, both having different shapes conforming to different types of coaxial cable connectors and are interchangeable. The body has a body receiving end, wherein the plunger is slidable therein. The fixed, first moveable and second moveable guideway plates have fixed, first and second guideways, each having different diameters, respectively. The die block comprises first and second die halves. The plunger is axially advanced to force the coaxial cable connector onto the coaxial cable end, radially contracting the coaxial cable connector into compression engagement with the coaxial cable end.

  • Publication number: 20120192359
    Abstract: A cable stripper with marking structure includes an upper main body, a lower main body, a blade seat installed on the lower main body, a micro-adjustable locating structure including a fixing rod connected with the upper main body and a locating plate movably connected on the fixing rod, and a marking structure including a support body fixed with the lower main body and a marking member connected with the support body and extending from the support body by a certain length. A free end of a coaxial cable can be inserted into the marking structure until the free end of the coaxial cable completely abuts against the locating plate. Then, the coaxial cable is rotated to form a mark on the surface of the skin of the coaxial cable. With the mark, the coaxial cable is prepared to insert into a terminal connector by a correct insertion depth.
