Abstract

The utility model discloses an in-ear headphone, a backshell and a wire fixing device thereof. The earphone comprises a backshell and a wire. The backshell is provided with a thread hole for the wire passing through. The wire is sleeved with a plastic conduit which tightly fits with the wire. The plastic conduit is at least provided with two clamping hooks. A ring of clamping bench used for hanging the clamping hooks is raised on the inner wall of the thread hole. As the clamping hooks are arranged on the plastic conduit, the plastic conduit can be directly hung on the backshell after threading, and the wire which tightly fits with the plastic conduit is fixed. Thus, knotting and sizing of the wire are not required so as to save labor and time for knotting and sizing of the wire, raise production efficiency of the in-ear headphone and reduce production costs of the in-ear headphone. In addition, the hard plastic conduit also plays a role in guiding to a certain degree during the threading process, thus bringing convenience for assembling of the soft wire.

Description

A kind of In-Ear Headphones and back cover thereof and wire fixing device

Technical field

The utility model relates to In-Ear Headphones and back cover thereof and wire fixing device field, in particular a kind of wire reliable In-Ear Headphones easy to assembly, fixing and back cover and wire fixing device.

Background technology

Existing In-Ear Headphones in process of production, the wire of the overwhelming majority all will pass through wires hole on back cover in the process of assembling, then tie a knot and gluing.

But at the production link of In-Ear Headphones, other operations of comparing, the operation of threading, knotting and gluing have taken the more artificial and time, have reduced In-Ear Headphones production efficiency, have increased the In-Ear Headphones production cost.

Therefore, prior art still haves much room for improvement and develops.

The utility model content

For solving the problems of the technologies described above, the utility model provides a kind of wire fixing device of In-Ear Headphones, can be convenient to the fixedly assembling of wire.

Simultaneously, the utility model also provides a kind of back cover of In-Ear Headphones, can be convenient to the fixedly assembling of wire.

And the utility model also provides a kind of In-Ear Headphones, can save the artificial and time of wire knotting and gluing.

The technical solution of the utility model is as follows: a kind of In-Ear Headphones, comprise back cover and wire, be provided with the through wires hole that adaptive described wire passes on described back cover, be set with a plastic catheter on described wire, described plastic catheter and described wire tight fit, at least be provided with two grabs on described plastic catheter, protrude the Ka Tai that a circle is used for the described grab of adaptive hook on the inwall of described through wires hole.

A kind of back cover of In-Ear Headphones is provided with one and is used for the through wires hole that wire passes on it, be used for the Ka Tai of hook grab on the inwall of described through wires hole to a projecting inward circle.

The back cover of described In-Ear Headphones, wherein: described Ka Tai is arranged on the root of this through wires hole along the radial direction of described through wires hole.

A kind of wire fixing device of In-Ear Headphones comprises that one is used for being sleeved on the plastic catheter on wire, and described plastic catheter and described wire tight fit are provided with two grabs that are used for being hooked on back cover at least on described plastic catheter.

The wire fixing device of described In-Ear Headphones, wherein: described grab is evenly distributed on the insertion end of this plastic catheter around the axial line of described plastic catheter.

The wire fixing device of described In-Ear Headphones, wherein: described wire is placed in the mould of described plastic catheter as mold insert in the process of the described plastic catheter of injection moulding.

A kind of In-Ear Headphones provided by the utility model and back cover and wire fixing device, owing to having adopted grab on plastic catheter, can directly plastic catheter be hooked on back cover after threading, and the wire of fixing and its close-fitting, need not thus again wire to be tied a knot and gluing, and then saved the artificial and time of wire knotting and gluing, and improved In-Ear Headphones production efficiency, reduced the In-Ear Headphones production cost; And the hard plastic conduit also played the to a certain degree effect of guiding in the threading process, has been convenient to the assembling of soft wire.
