Abstract

The utility model discloses a lap guard earphone cord, including shell and 2 bar at least wires, all the wire is followed shell length direction distribute side by side in the shell is inside just to be passed through the shell forms the interval, the cross section of shell is the long circle, the cross section of wire is circular, each the wire includes the filler, set up in 2 piece at least enamelled copper wires around the filler with be used for fixing the winding layer of enamelled copper wire, the cross section of filler be circular and with the wire is concentric, all the enamelled copper wire is followed the center annular of filler distribute with the filler outside. The utility model provides the lap guard earphone cord who arrives through increase shell width, increases the degree of difficulty that earphone cord oneself was knotd to with all wires set up side by side in inside the shell, increase the earphone cord holistic prevent stretching draw, the distortion degree, increase the bulk strength of earphone cord, simple structure, convenient to use.

Description

A kind of lap guard earphone cord

Technical field

The utility model relates to a kind of lap guard earphone cord.

Background technology

In social life of today, data wire is absolutely necessary electronic product, substantially everyone needs to use every day, the data wire CF of now is very single, color is in the majority with black, shape of cross section is essentially circular, produces the problem of knotting when depositing improperly through being everlasting, and stretching to draw in the process with distortion and easily rupture repeatedly.

Utility model content

The purpose of this utility model provides a kind of and can prevent tangled up and knotted to solve above-mentioned the deficiencies in the prior art and can stand repeatedly to stretch the lap guard earphone cord drawn with distortion.

To achieve these goals, a kind of lap guard earphone cord designed by the utility model, comprise shell and at least 2 wires, all described wires are distributed in described enclosure side by side along described outer cover length direction and form spacing by described shell, the cross section of described shell is Long Circle, the cross section of described wire is circular, described in each, wire comprises filler, be arranged at least 2 enamel covered wires around described filler and the winding layer for fixing described enamel covered wire, the cross section of described filler is circular and concentric with described wire, all described enamel covered wires are outside the center annular distribution and described filler of described filler, described winding layer wraps up all described enamel covered wires completely and forms described wire external layer.

Described winding layer is enamelled wire.

Also comprise the insulating barrier be arranged at outside described wire, described insulating barrier is arranged between described winding layer and described enamel covered wire.

Described insulating barrier is made up of clear PE heart yearn.

Described filler is the anti-elater of 200D or the anti-elater of 400D.

Described shell is made up of TPE environmental protection sizing material.

A kind of lap guard earphone cord that the utility model is mentioned, by increasing outer casing width, increase the difficulty of earphone cord oneself knotting, and all wires are arranged side by side in described enclosure, increase earphone cord entirety anti-stretch draw, degreeof tortuosity, increase the bulk strength of earphone cord, structure is simple, easy to use.
