Patent number: 11043782Abstract: 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.Type: GrantFiled: September 26, 2018Date of Patent: June 22, 2021Assignee: EZconn CorporationInventor: Cheng Hui Wang
