Connection pipe of carbon fiber compound core lead

The utility model discloses a carbon fiber composite core conductor connection tube able to connect a conductor in an overhead power line. The utility model is provided with a coupling device composed of a A coupling part as well as a B coupling part at the center inside an external pressure connection tube and liner tubes at the two sides inside the external pressure connection tube; wherein, the two ends of the coupling device are symmetrically provided with wedge holders with built-in wedge grips. By utilizing the feature that the wedge grips at the two sides of the coupling device can move inside the wedge holders, the utility model tightly clips the carbon fiber composite core under the effect of the tension of the conductor when the temperature changes, and splices the conductor through the coupling device; meanwhile, the utility model can also protect the carbon fiber composite core when crimping under the effect of the liner tubes. Thus, the utility model avoids the damage or fracture to the carbon fiber, dramatically enhances the loading capacity of the core, and effectively reduces the sag of the conductor; the utility model also has the advantages of the reasonable design structure, unique and novel conception, impact and fatigue resistance, stable and reliable performance, and easy installation and use and being favorable in promotion and application.
