Description

A spiral earphone cable

technical field

The utility model relates to an earphone wire, in particular to a spiral earphone wire.

Background technique

More and more multimedia devices use headphones to connect calls or answer calls, so that during the answer or call, the user can free up his hands to do other things, and in a crowded environment, wearing headphones to enjoy audio and video Products can avoid disturbing others. Therefore, earphones have been used more and more. At present, the earphone wires used in earphones on the market have a single shape and color, and most of them are flat or round wires. Moreover, the color is single, and it is not convenient for manufacturers to print patterns on the surface of the slender headphone cable. Although there are two colors such as black and white headphone cables, the color has no sense of hierarchy, the appearance is ordinary, the design is not novel enough, and it is not easy to identify.

Therefore, it is necessary to provide a layered earphone cable to overcome the above-mentioned deficiencies in the prior art.

Utility model content

The purpose of the utility model is to provide a spiral earphone cable, which is full of layers, easy to identify, novel in design and beautiful in appearance.

In order to achieve the above object, the utility model provides a spiral earphone cable, the spiral earphone cable includes several core wires and a transparent insulating layer, the core wires are helically twisted together in parallel, and the transparent insulating layer is along the A piercing hole is opened in its length direction, and the core wire is passed through the piercing hole, and the hole wall of the piercing hole is in a spiral shape corresponding to the core wire.

Preferably, the number of the core wires is three.

Preferably, each of the core wires includes a conductor and a conductor insulation layer covering the conductor.

Preferably, the outer wall of the transparent insulating layer has a spiral shape corresponding to the core wire.

Preferably, the core wires include digital signal core wires and power core wires.

Preferably, the diameter of each core wire is 0.8mm˜1.2mm.

Compared with the prior art, the spiral earphone cable of the present invention includes several core wires and a transparent insulating layer, the core wires are helically twisted together in parallel, and the transparent insulating layer is provided with holes along its length direction. A hole, the core wire is passed through the piercing hole, and the hole wall of the piercing hole is in a spiral shape corresponding to the core wire. The spiral piercing holes correspond to the helically twisted core wires, and the transparent insulating layer is transparent, showing a layered spiral shape, beautiful appearance and novel design. In addition, the helically twisted core wire is bound in the helical piercing hole, so it is not easy to move, nor can it be pulled out from the piercing hole, so the structure is stable and compact.

detailed description

Several different preferred embodiments of the present invention will be described below with reference to the accompanying drawings, wherein the same reference numerals in different drawings represent the same components.

The utility model aims to provide a spiral earphone cable 1, which is full of layers, easy to identify, novel in design and beautiful in appearance.

As shown in Figures 1 and 2, the spiral earphone cable 1 includes several core wires 10 and a transparent insulating layer 20, the core wires 10 are helically twisted together in parallel, and the transparent insulating layer 20 has a through hole 21 along its length direction. , the core wire 10 is inserted into the penetration hole 21 , and the wall of the penetration hole 21 is in a spiral shape corresponding to the core wire 10 . In this embodiment, the number of core wires 10 is three, and in other embodiments, it can be adjusted as required. The transparent insulating layer 20 is transparent or translucent.

Each core wire 10 includes a conductor 12 and a conductor insulating layer 14 covering the conductor 12 . The outer wall of the transparent insulating layer 20 can be circular, as shown in FIG. 1 , or can be spiral corresponding to the core wire 10, as shown in FIG. 2 . The core wires 10 include digital signal core wires 10 and power core wires 10, and each core wire 10 has a diameter of 0.8mm˜1.2mm.

Compared with the prior art, the helical piercing holes 21 correspond to the helically twisted core wires 10, and the transparent insulating layer 20 is transparent, presenting a layered helical shape, beautiful in appearance and novel in design. In addition, the helically twisted core wire 10 is bound in the helical insertion hole 21 , so it is not easy to move, nor can it be pulled out from the insertion hole 21 , so the structure is stable and compact.

The above disclosures are only preferred embodiments of the present utility model, and of course the scope of rights of the present utility model cannot be limited with this. Therefore, equivalent changes made according to the patent scope of the utility model are still covered by the utility model. scope.
