Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.

As shown in Figure 1, the utility model provides a kind of earphone patchcord, including switching wire box 1, the switching wire box 1 Inner surface is equipped with shielding stratum reticulare 8, and the switching wire box 1 is internally provided with transit line plate 2, and the transit line plate 2 passes through support Bar 9 is vacantly mounted on inside switching wire box 1, and the transit line plate 2 is electrically connected with USB heads 3, and USB heads 3 are located at patchcord Outside box 1,2 left side of the transit line plate is electrically connected with the first receiver J-Horner 4 and the second receiver J-Horner 5, first ear Machine transplanting of rice mouth 4 and the second receiver J-Horner 5 are fixedly mounted on inside switching wire box 1, first receiver J-Horner, 4 and second receiver J-Horner 5 left sides are equipped with protection attachment device 6；

In present embodiment, switching wire box 1 is mainly used for the installation of earphone interface and transit line, shielding stratum reticulare 8 Setting, avoids influence of the external noise signal to audio signal, and transit line plate 2 is used to turn the audio signal in terminal It is changed to the audio signal that earphone can receive, transit line plate 2 is vacantly mounted on by supporting rod 9 in switching wire box 1, Ke Yijia The radiating efficiency of fast transit line plate, is effectively protected transit line plate, and USB connect with terminal, and the audio of terminal is believed It number is transmitted on transit line plate 2, USB heads is not limited in present embodiment, TYPE-C heads, transit line plate can also be used 2 are converted to the audio signal that terminal transmission comes the audio signal that earphone can identify, by be connected to the first receiver J-Horner 4 with And the second earphone on receiver J-Horner 5 plays out audio, and in the present embodiment, the first receiver J-Horner 4 and the second receiver J-Horner 5 OMTP standards are respectively adopted and CTIA standards carry out wiring, different earphones can be suitable for, protection attachment device 6 can not only It enough prevents earphone from falling off from the first receiver J-Horner 4 or the second receiver J-Horner 5, while being also avoided that earphone cable drawing after earphone connection Earphone thread breakage caused by pulling.

The protection attachment device 6 includes the mounting hole 601 being arranged in switching wire box 1, and 601 right side of the mounting hole is set There are two slide bars 602, two 602 middle parts of the slide bar that fixed plate 603 is installed, is slidably connected on two slide bars 602 Two fixed strips 604, two fixed strips 604 are respectively connected with adjustable spring 605 with fixed plate 603 and 1 inner wall of interconnecting device, Two 604 both ends of the fixed strip are mounted on the movable plate 606 of half cone planar, 604 section semicircular in shape of the fixed strip, and Two fixed strips 604 form cylinder after closing up.

In present embodiment, protection attachment device 6 can not only prevent earphone from being inserted from the first receiver J-Horner 4 and the second earphone It falls off on mouthfuls 5, while being also avoided that earphone thread breakage caused by earphone cable is pullled after earphone connection, when in use, it is only necessary to will Headset plug pushes movable plate 606 to, and after 607 side of movable plate is by the thrust of headset plug, movable plate 606 is moved to both sides, The fixed strip 604 being connect simultaneously with movable plate 606 is moved along slide bar 602 to both sides, and adjustable spring 605 is compressed, and earphone is worked as Plug is loosed one's grip after being inserted into the first receiver J-Horner 4 or the second receiver J-Horner 5, due to the elastic force of adjustable spring 605, two fixations Item 604 fixes earphone, and when earphone cable is by the larger power of pullling, the work of power occurs with internal movable plate 606 for headset plug With fixed strip 604 being pushed open, earphone is pulled out at this time, it is therefore prevented that earphone was subject to pull, and power is excessive to cause earphone thread breakage.

Further, sealing telescopic platform 7 is installed, the sealing is stretched between 601 inner wall of the fixed strip 604 and mounting hole Contracting platform 7 includes outsourcing coaming plate 701 and interior encirclement plate 702, and the outsourcing coaming plate 701 is slidably connected with interior encirclement plate 702, described outer It surrounds plate 701 to be fixedly connected on 601 inner wall of mounting hole, the outsourcing coaming plate 701 is fixedly connected on 604 outer surface of fixed strip On.

In present embodiment, the setting of telescopic platform 7 is sealed so that mounting hole 601 is inside and outside to keep good leakproofness, avoids 1 inside of switching wire box influences the working performance of patchcord into dust, and in the present embodiment, interior encirclement plate 702 is always It remains and is moved synchronously with fixed strip 604 so that switching wire box 1 is inside and outside to be separated by sealing telescopic platform 7, plays the effect of sealing Fruit.

It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this practicality is new in other specific forms Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this practicality is new The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing in the equivalent requirements of the claims will be fallen All changes in justice and range are embraced therein.Any reference numeral in claim should not be considered as limitation Involved claim.
