Abstract
The utility model relates to an integrally-molding composite material insulation drive bar provided with an insert, which comprises an integrally-molding composite material insulation bar with metal insert parts and a coupling, wherein, the metal insert parts are positioned at two ends of the composite material insulation bar, and the coupling is connected with the composite material insulation bar through the metal insert parts. The bond strength of the integrally-molding metal insert parts and a composite material layer can be designed according to the requirements of an insulation drive component, and can be exponentially increased compared with the adhesive bonding structure, and the stability and the reliability are high. Because the composite material insulation bar is made by the integrally-molding process, the bonding process of the coupling is avoided, and the processing technique is simplified. Meanwhile, reinforced material of alkali-free glass fiber and the like is added in epoxide resin, so the mechanical property of the composite material insulation bar is greatly improved. The abutting end of the metal insert parts and the composite material layer is designed to a circular bead according to the influence of the shape of the insert to the electric field distribution, and the concentration of the field strength at the end parts of the metal insert parts can be reduced.
