One can conduct electricity the conductive cap that connects Edison base second utmost point, and it is fixed in insulator, and insulation gap between it and the spiral conductor wire.

In the utility model one preferred embodiment, this spiral conductor wire is a metal coil spring.

In the utility model one preferred embodiment, this insulator is a plastic casing, is provided with the helicla flute that cooperates the spiral conductor wire outside this plastic casing.

In the utility model one preferred embodiment, the surface of revolution outside the partly outstanding insulator of this spiral conductor wire.

In the utility model one preferred embodiment, this spiral conductor wire lower end is installed with a conduction straight section, offers first through hole that runs through inside and outside on this insulator, and this conduction straight section passes first through hole and stretches within the insulator; Other sets sideline conduction and connects the conduction straight section.

In the utility model one preferred embodiment, offer second through hole that runs through inside and outside on this insulator, other sets a center line and passes second through hole outward and stretch out outside the insulator from interior, and conduction connects conductive cap.

The technical program is compared with background technology: owing to adopt metal threaded line to substitute the metal threaded shell of background technology, therefore overcome the existing deficiency of background technology, and had following advantage: 1, the metal materials are few, and cost is low, economize on resources; 2, outward appearance is succinct, and is attractive in appearance; 3, can directly firmly connect metal threaded line and insulator during injection mo(u)lding, thereby need not other assembly technology, operation is few, the working (machining) efficiency height, and cost is low; 4, there are not welding, environmental protection.Because this spiral conductor wire is a metal coil spring, so this elasticity can strengthen the connectivity robustness between conductor wire and the insulator.Owing to be provided with the helicla flute that cooperates the spiral conductor wire outside this plastic casing, therefore can fixedly positioning the spiral conductor wire.Because therefore the surface of revolution outside the partly outstanding insulator of this spiral conductor wire can guarantee that the conduction between spiral conductor wire and the Edison base connects.Because this spiral conductor wire lower ends downward extends into the conduction straight section, this conduction straight section stretches within the insulator, therefore is convenient to processing, can save manufacturing procedure.
