Because the invention is used for fixing the electric wire, the electric wire is provided with current and the coil spring 5 is conductive, the invention has the insulation effect by fixedly connecting the rubber ring 42 at one end of the coil spring 5 for fixing the electric wire, and meanwhile, the rubber has certain elasticity and can better fix the electric wire.
Because the inner surface of the rubber ring 42 and the outer surface of the electric wire are smooth, the electric wire is likely to slide, the copper strip 421 is fixedly connected to the inner surface of the rubber ring 42, and the section of the copper strip 421 is triangular, so that when the coil spring 5 contracts and fixes the electric wire in the rubber ring 42, the copper strip 421 can clamp the outer surface of the electric wire, so that the electric wire has a better fixing effect, meanwhile, the copper strip 421 is connected with a relay in an electric energy meter, and because of the plurality of copper strips 421, when one copper strip 421 is damaged, the electrification to the interior of the relay is not influenced, so that the electric wire has better usability.
