Embodiment
The perspective view of the first spring electric wire 100 that the utility model embodiment provides as shown in Figure 1, this spring electric wire 100 has elasticity, namely can be made the length of spring electric wire 100 by tractive when using, after traction force disappears, spring electric wire 100 just can make the retracted in length of himself shorten by self tightening power.Spring electric wire 100 comprises the oversheath 1 with helical structure and the wire be located in this oversheath 1, and the material of oversheath 1 is polyvinyl chloride or polyurethane.The wire of this inside, spring electric wire 100 top 11 is connected with the circuit of electronic equipment internal, the end 12 of this spring electric wire 100 can be electrically connected with external equipment, for powering to external equipment or carrying out signal output, think in the utility model that the convenience-for-people charger that electric motor car charges is example, spring electric wire 100 top 11 is connected with convenience-for-people charger, end 12 is connected with electric motor car charging plug, for charging to electric bicycle.Pass through tractive charging plug when user uses to be elongated by the helical structure of spring electric wire 100, can reach the position needing to use to make charging plug, after finishing using, unclamp charging plug, spring electric wire 100 makes retracted in length by the power that tightens of self.
As shown in Figure 1, spring electric wire 100 is also provided with elastic tensioning part, and this elastic tensioning part tightens power for what strengthen spring electric wire 100, and this elastic tensioning part can be have flexible spring or elastica.Tension part in Fig. 1 is a spring 2, can certainly be the structure that many springs are joined together to form, the material of spring can be plastics or metal, and is preferably the spring 2 of metal material, such spring 2 pulling force is comparatively strong, and what contribute to enhancing spring electric wire 100 tightens power.Spring 2 has multiple set-up mode on spring electric wire 100, the inside of spring electric wire 100 can be arranged on, and the structure be preferably in Fig. 1, spring 2 is arranged in a parallel manner in the accommodation space 13 of oversheath 1 helical structure formation, this setup is succinct, and attractive in appearance, and the vertically disposed pulling force of spring 2 is the strongest, and conveniently change after the power that tightens of spring 2 self weakens.The top of spring 2 to be connected with the casing of charger by syndeton and to be fixed, and this syndeton can be that the hook ring arranged respectively on charger casing with spring 2 hooks conjunction mutually; Also can be that connecting hole is set on charger casing, by bolt and pressing plate, spring 2 is fixed; Also can be spring 2 is directly bonded in charger casing on wait all methods that can be fixed, certainly spring 2 can also be fixed on the top 11 of spring electric wire oversheath 1.
The end 22 of spring 2 by syndeton and spring electric wire 100 end 12 be connected and fixed, this syndeton is that oversheath 1 end 12 hooks conjunction mutually with the hook ring structure that spring 2 end 22 is arranged respectively; Other structures can also passed through directly to bond together etc. or can be fixed also can be fixed on by spring 2 end 22 on other plug portions of being connected with spring electric wire 100.Such as, when the end 12 of spring electric wire is connected with the deconcentrator with multitapped charging output line, then an annulus is set in deconcentrator part, the end 22 of spring 2 arranges snap fit, by snap fit hook joint on this annulus, realize fixing spring 2.By spring 2 is fixed on spring electric wire 100, power is tightened with what strengthen spring electric wire 100, spring electric wire 100 is used and no longer pulls rear timely retraction, avoid because of spring electric wire 100 use too much tighten power weaken after and the spring electric wire 100 that causes is straightened, and then cause spring electric wire 100 put easily chaotic problem.
Certainly, spring 2 also can adopt spiral form to wear and be fixed in the sleeve pipe of this oversheath 1, spring inside diameter by spring 2 is set to identical with the internal diameter of spring electric wire 100, by after spring 2 outer wrap insulating barrier and inner lead be located in oversheath 1 in the lump, also can directly be made of one the structure of formula with oversheath 1.Spring 2 can be hidden by this setup be located at spring electric wire inside, and what the outward appearance not affecting spring electric wire 100 can also strengthen spring electric wire 100 tightens power.
Spring 2 shown in Fig. 2 is arranged on the outside of spring electric wire 100 oversheath 1, this spring 2 can adopt the outside being arranged on described oversheath 1 helical structure as shown in FIG. with parallel form, and identical with the fixed form of above-mentioned spring 2 in spring electric wire 100 accommodated inside space 13 for the fixed form of spring 2.Certainly, spring 2 also can adopt spiral form dish to be located at the jacket exterior of this oversheath 1, as shown in Figure 3, be set to identical by the spring inside diameter of spring 2 and the internal diameter of spring electric wire, by bonding or other fixed forms, spring 2 be fitted on the surface of spring electric wire 100 oversheath 1.By spring 2 is fixed on spring electric wire 100, power is tightened with what strengthen spring electric wire 100, spring electric wire 100 is bounced back in time when outside traction force disappears, avoid because of spring electric wire 100 use too much tighten power weaken after and cause be straightened after put chaotic problem.
Certainly, above-mentioned elastic tensioning part can also be elastica, such as rubber, latex etc. have the line of elastic material, the set-up mode of elastica can be identical with above-mentioned spring 2, inside or the outside of spring electric wire can be arranged on too, and in the accommodation space 13 that formed of the helical structure being preferably arranged on spring electric wire oversheath 1, arrange like this can strengthen spring electric wire 100 well tighten power, operation is succinct simultaneously, and attractive in appearance.Certainly, elastic tensioning part also can be the tension part of other structures or form, as long as on the casing that can be fixed on electronic equipment and the end 22 of spring electric wire 100 or the top 21 being fixed on spring electric wire 100 and end 22, what can realize strengthening spring electric wire tightens power.
Please refer to Fig. 4 and Fig. 1, a kind of charger 200 that the utility model embodiment provides, it comprises charging mainboard 3 and spring electric wire 100, spring electric wire 100 has top 11 and the end 12 relative with top 11, top 11 is electrically connected to charging mainboard 3, end 12 can be electrically connected to storage battery 4, to charge to storage battery 4; Spring electric wire 100 also comprises elastic tensioning part, and elastic tensioning part tightens power for what strengthen spring electric wire 100, and to avoid the spring electric wire 100 of charger 200 because of after the too much elasticity of access times weakens, that causes puts chaotic phenomenon.
In sum, the utility model by arranging an elastic tensioning part on the spring electric wire of charger, what strengthen spring electric wire further by tension part tightens power, thus avoid spring electric wire too much because user constantly pulls access times, the power that tightens of spring electric wire is caused to weaken and lost efficacy, and then spring electric wire be straightened after put unordered, and easily chaotic problem.
