the anti-loose earphone wire for the headset comprises a sheath, a lead and a plug electrically connected with the lead, wherein the sheath is fixedly sleeved at the joint of the lead and the plug in an injection molding mode, and external threads connected with external threaded holes are formed at the end part of the peripheral side surface of the sheath; the outer peripheral side surface of the sheath is also provided with a convex ring which extends outwards and is positioned at the bottom end of the external thread, and the top end surface of the convex ring is provided with a first sealing ring which is sleeved on the outer peripheral side of the sheath.

Wherein, the top end face of bulge loop is seted up and is used for the slot of holding first sealing washer.

Wherein, the plug is provided with at least two seal grooves which are arranged at intervals along the axial direction of the plug.

Wherein, all be equipped with the second sealing washer of cover on the plug in each seal groove.

Wherein, still include the earlap, the earlap is seted up and is supplied sheath male screw hole, and threaded hole is equipped with the internal thread with external screw thread fit.

The utility model has the beneficial effects that:

compared with the prior art, the anti-loosening earphone wire for the headset is characterized in that the external thread in threaded connection with the external threaded hole is arranged on the sheath, so that the earphone wire can be prevented from loosening through threaded connection, the problem that the earphone wire is easy to loosen in the past is solved, in addition, the sheath is also provided with the convex ring and the sealing ring, the convex ring can extrude the sealing ring under the fastening state of the earphone wire, and the sealing ring can block the gap between the earphone wire and the earshell, so that sealing is realized, and the waterproof and dustproof effects are achieved.
