Microscler all insulation window type connects

The utility model discloses a microscler all insulation window type connects, its technical scheme main points are, including the annular metallic pipe, all insulation outer tube that annular metallic outside of tubes wall fixedly connected with was made by transparent material, and the annular metallic pipe be close to the intermediate position sentence in the cross section seted up two windows for reference surface bilateral symmetry. The utility model aims at providing a microscler all insulation window type connects in when butt joint, can see the concrete mounted position of wire clearly, guarantees that both ends wire head all is located the intermediate position of tubular metal resonator, makes wire and tubular metal resonator area of contact maxmizing, prevents direction roll -off or take place not hard uply from the metal pipe, avoids taking place contact failure, and the be brought into contact effect reaches the best.
