ICSE培训资料10：施工工具（同轴电缆） - 美国理想.pptVIP

同轴电缆施工工具 同轴电缆的布放与屏蔽型双绞线类似 使用符合同轴电缆结构特点的工具进行剪切及剥线 专用连接器及端接工具 双绞线验证与认证设备同样适用于同轴电缆 同轴电缆分类 同轴电缆结构 同轴电缆施工工具——剪切 同轴电缆施工工具——剪切 同轴电缆施工工具——剥线 Stripping coax – F-style 同轴电缆施工工具——剥线Coax Stripmaster? Spring action grips strips Speeds up 2-step stripping Different blades for: RG6 RG59 RG6 Quad 同轴电缆施工工具——剥线Stripping coax with the Stripmaster? 45-262 同轴电缆施工工具——剥线Stripping with the Coax Stripper 45-524 同轴电缆施工工具——剥线Adjusting the Coax Stripper 45-524 同轴电缆施工工具——剥线Replacing the blade cassette 同轴电缆施工工具——端接About “F” Connectors One-piece Most preferred, easiest installation Two-piece More pullout strength Twist-on What twists on will twist off… 同轴电缆施工工具——端接 About “F” Connectors Must be used for all open CATV outlets Eliminates leakage and ingress, which lead to poor signal quality 同轴电缆施工工具——端接F-Connector Tool Using leverage to install an F connector will seat every connector properly Most video signal problems are caused by loose connections. Tighten all connectors with an F-Connector tool. 同轴电缆施工工具——端接Coax Strip Crimp Tool Cuts, Strips Crimps RG-6 RG-59 No need to carry separate tools Good for occasional contractor use 同轴电缆施工工具——端接Terminating coax - CrimpMaster? Consistency repeatability More leverage, less installer fatigue The same crimp every time 28 interchangeable dies For the installer with more than an occasional crimp to do 同轴电缆施工工具——剥线Stripping coax - BNC Accuracy, efficiency, repeatability 同轴电缆施工工具——剥线To use the 45-520 同轴电缆施工工具——剥线Center Conductor Cutter 35-060 同轴电缆施工工具——端接BNC/TNC Connectors Primary use today is for video/security installations Was an early data connector Looks like a difficult termination, but can be the easiest 同轴电缆施工工具——端接Three-piece BNC Recommended Fastest Easiest Captive contact pin Gas-tight crimp 同轴电缆施工工具——端接Two-piece BNC Less expensive More labor No captive contact pin No gas tight crimp 同轴电缆施工工具——端接Twist-on BNC Quickest, easiest Least reliable No captive contact pin No gas-tight crimp Can be affected by thermal change Installer
