Relatively rotating of each linkage section, it mainly acts on also is convenient be connected with the spiral of inner wire (because of the inner wire wall thickness is thinner, it is bigger that other connect difficulty), is connected with the front and back inner wire like this can distinguish independently to connect by precession.Series connection is rotationally connected, obviously the technical staff can understand, can between two linkage sections, increase and connect changeover portion, as adopt three sections or above connection, and also can adopt two sections directly to be and to be rotationally connected, mode is rotationally connected, the technical staff obviously can understand can have multiple, as long as can realize being rotationally connected, there is no too many qualification, specifically can understand by the help for example of back.
Linkage section end spiral mainly is for strengthening and the bonding strength that is connected inner wire, to guarantee an easy connection, not coming off in the two connection rear haulage processes.Can be different and different according to inner wire, spiral inner wire for example, its screw thread preferably cooperates with inner wire spiral; Polished rod then can be provided with spiral separately, also can adopt as preceding spiral, just need join the screw thread scraper of an interworking screw thread in addition, processes connection spiral at smooth inner wire inner surface.
The connector external diameter is not more than the extrusion die internal diameter, mainly is to consider that from passing through extrusion die nib angle connection speed is faster like this, and the time is shorter, and waste also still less.
Connector can be made by metal, also can be the nonmetal making of heatproof (for example 〉=135 ℃ extrusion temperature), and material is not particularly limited.
The utility model radio frequency coaxial electric cable for mobile communication is produced connecting rod, has two sections connectors that are composed in series relative turntable at least owing to make, and linkage section can rotate to different directions respectively before and after making, and realizes fast the continued access of front and back inner wire is connected.With respect to prior art; use this connecting rod to have: continued access is quick; time is short; continued access before and after greatly facilitating in the production process between the inner wire connects; can be in the cable continuous flow procedure; realize not shutting down continuous production; joint passes through extrusion die; as long as cut off seldom one section, to take out joint and reuse, front and back continued access section quality is good; do not had the fare waste and shut down waste; significantly reduce the raw-material waste of cable, and cut off part and can also be used as routine inspection, and do not needed to cut separately check section.
Below in conjunction with a specific embodiment; utility model is further understood in exemplary illustration and help; but the embodiment detail only is for utility model is described; do not represent utility model design whole technical schemes down; therefore should not be construed as the technical scheme qualification total to the present invention, some do not depart from the unsubstantiality of utility model design and change In the view of the technical staff; for example change or replace, all truely use novel protected scope so that technical characterictic with same or similar technique effect is simple.
