Detailed Description

The utility model is further described with reference to the following examples.

As shown in fig. 1 to 5, the waterproof and dustproof structure of the earphone cord for the headphone according to the present invention includes an earphone shell 1, an earphone cord, and a dustproof cover 3. The earmuff 1 is provided with a mounting hole for inserting the sheath 22, and the bottom end of the mounting hole extends downwards to form a mounting cylinder 11 for inserting the sheath 22.

In this embodiment, the earphone cable includes a sheath 22, a conductive wire and a plug 21 electrically connected to the conductive wire, the sheath 22 is fixedly sleeved at the joint of the conductive wire and the plug 21 by injection molding, and a clamping groove 51 is formed in the peripheral side surface of the sheath 22.

In order to improve the waterproof and dustproof performance of the earphone wire connected with the earmuff 1, the dust cover 3 is sleeved on the outer peripheral side of the sheath 22, the bottom end of the dust cover 3 is inserted into the clamping groove 51, the bottom end of the dust cover 3 is bonded in the clamping groove 51 through the adhesive, so that the bottom end of the dust cover 3 is effectively connected with the clamping groove 51 in a sealing manner, the specific adhesive can be glue such as epoxy resin, or single-component structural adhesive on the market is adopted, only sealing bonding needs to be realized, and the selection can be specifically carried out according to actual needs.
