The technical solution adopted in the utility model is: design a kind of earphone cord automatic retraction device, it comprises: Wiinding cartridge, strip conductor, wind spring, spool, support, sliding contact and retractable earphone cord; Described Wiinding cartridge is the roll structure, and spool is positioned at the Wiinding cartridge center, and the Wiinding cartridge both sides are provided with catch, and the recess that forms between two catch is a winding space, and the recess periphery is provided with some solder joints, and weld with it described earphone cord the inner; Described Wiinding cartridge inner ring is fixed with the some annular strip conductors that gradually increase identical with number of welds, and described solder joint electrically connects with the corresponding one by one realization of strip conductor; The periphery of spool is provided with wind spring, and wind spring drives Wiinding cartridge and strip conductor rotation; One end of spool is fixed a support, and support is provided with strip conductor and cooperates the some sliding contacts that contact, and the lead-out wire of sliding contact is derived along support and connect audio signal; Be provided with stop near the receiver place on the described earphone cord.
In the such scheme, described wind spring is short and the suitable sheet type spring of volume power.
In the such scheme, described sliding contact comprises the stage clip of contact and top, contact.
In the such scheme, described support is the cuboid of hollow.
In the such scheme, described earphone cord adopts sheet-like cable line, soft alloy line or common two-wire.
In the such scheme, described stop adopts the deconcentrator or the microtelephone of earphone cord.
In the such scheme, described Wiinding cartridge is provided with positioning checkpoint outward.
In the such scheme, the recess periphery is provided with 4 solder joints, and the Wiinding cartridge inner ring is fixed with 4 annular strip conductors that increase gradually, and support is provided with 4 sliding contacts that match with strip conductor.
The beneficial effects of the utility model are: it makes earphone cord to be drawn out in use, is wound in automatically on the Wiinding cartridge when not using, and is convenient to earphone cord is managed.Since be wrapped on the Wiinding cartridge at ordinary times, dog leg not easy to break, and earphone cord prolongs useful life.The scope of application is extensive, can be used in the device of needs use earphones such as mobile phone, walkman.
Description of drawings
Fig. 1 is the structural representation of earphone cord automatic retraction device;
Fig. 2 is the schematic perspective view of earphone cord automatic retraction device.
Embodiment
Below in conjunction with drawings and Examples, further specify the utility model.
See figures.1.and.2, earphone cord automatic retraction device of the present utility model comprises: Wiinding cartridge 4, strip conductor 7, wind spring 8, spool 13, support 9, sliding contact 6 and retractable earphone cord 1; Wiinding cartridge 4 is the roll structure, spool 13 is positioned at Wiinding cartridge 4 centers, and Wiinding cartridge 4 both sides are provided with catch, and the recess 12 that forms between two catch is winding space, the recess periphery is provided with four solder joints 5, and four end points of earphone cord weld at solder joint 5 places respectively; Wiinding cartridge 4 inner rings are fixed with four 7 one corresponding ground of 7, four solder joints 5 of annular strip conductor and four strip conductors that increase gradually and electrically connect; The periphery of spool 13 is provided with wind spring 8, and wind spring can adopt short and the suitable sheet type spring of volume power, and wind spring 8 drives Wiinding cartridge 4 and strip conductor 7 rotates to the take-up direction together; The front end of spool 13 is fixed a support 9, and support can be the cuboid of hollow, and support 9 is provided with strip conductor 7 and cooperates four sliding contacts 6 that contact, and the lead-out wire 10 of sliding contact 6 connects the mainboard audio signal from support 9 interior derivation; Be provided with stop 3 near receiver 2 places on the earphone cord 1.
Sliding contact 6 comprises the stage clip of contact and top, contact, and the effect of stage clip is that the contact is contacted with strip conductor 7 all the time, is in UNICOM's state.
