Description

A kind of earphone cord structure

Technical field

The utility model belongs to earphone technical field, relates to a kind of earphone cord structure.

Background technology

Traditional wired earphone has two kinds of bend resistance modes at plug and earphone cord junction, the one, as shown in Figure 1, by joint overstriking, make joint not bent, to keep inner lead joint can not be pullled and cause off-line, be also difficult for causing that because frequent bending causes joint crust to break wire is exposed; The 2nd, adopt multiple and the vertically arranged sheet clip of wire to be set shown in Fig. 2 in joint, can only flexural deformation in minimum space with limiting joint, to prevent that joint from fractureing.Above-mentioned two kinds of modes all prevent that by preventing that wire bending is next inner lead Joint's falling off and joint from fractureing, but find after long-term use, and earphone cord crust breakdown point often appears at not bent connector end, causes inner lead to expose, and affects earphone quality.

Only rely on several superfine copper wires being connected between the earphone cord of earplug end and earplug inner member, therefore need firm tramline to avoid that copper wire joint is stressed to come off, cause earphone to lose efficacy.The fixing method of tradition is that earphone cord is directly accessed in earplug, and the wire in earphone is made a call to a knot, makes it be stuck in the exit of earplug shell.This inside configuration is easily loosening, pull for a long time inner knot can become tighten little deviate from, cause the junction of wire and inner member to come off.

When earphone need to carry, be usually by by folding earphone cord or curl up after pack pocket into, folding for several times or curling up to cause earphone cord crust to break from burst, expose inner lead, and aforesaid joint is damaged, and also has some relations with folding the curling up of earphone cord.

Utility model content

For addressing the above problem, the utility model provides a kind of earphone cord structure, thereby has reached the effect of avoiding earphone cord to fracture.

The utility model is achieved by following technical solution.

A kind of earphone cord structure, the earphone cord that comprises earplug, plug and earplug and plug are coupled together, described earphone cord comprises external insulation layer, is wrapped in the earphone core in external insulation layer and is located at respectively A bulge structure and the B bulge structure at external insulation layer two ends, described A bulge structure and B bulge structure are stuck in the shell end outlet place of earplug end and plug end, are provided with folding stretching structure in described external insulation layer stage casing.

The described earphone core that is positioned at folding stretching structural sections is spring-like screw arrangement; Described earphone core comprises wire and inner insulating layer, and described inner insulating layer is tightly coated on conductive line surfaces; The A bulge structure at described earphone cord two ends and B bulge structure be bonded in respectively in earplug shell and plug body in; Described inner insulating layer adopts flax fiber material to make.

The beneficial effects of the utility model are:

A kind of earphone cord structure described in the utility model, by establishing bulge structure at earphone cord external insulation layer two ends, earphone cord two ends are tightly stuck in to the end of earplug and plug body, strengthen the tensile property of joints, earphone cord two ends, reach guarantee earphone cord inner lead stable, the effect of difficult drop-off;

By the inner insulating layer of making at the coated flax fiber material of conductive line surfaces, increased the tensile property of wire, make earphone cord more not fragile, even and external insulation layer break, inner insulating layer is also can guardwire unlikely, and it is outside exposed;

By folding stretching structure being set in earphone cord stage casing, make earphone to need to elongate or shrink according to using, because inner lead is also spring-like screw arrangement, can realize and shrinking and stretch function with external insulation layer folding stretching structure well, and anti-bending strength is better, in the time carrying, can reduce wire fold by after shrinking, be convenient for carrying, not fragile.

Embodiment

Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but described in claimed scope is not limited to.

As Fig. 3, Fig. 4, shown in Fig. 5, a kind of earphone cord structure described in the utility model, comprise earplug 1, plug 2 and the earphone cord 3 that earplug 1 and plug 2 are coupled together, described earphone cord 3 comprises external insulation layer 31, be wrapped in the earphone core 35 in external insulation layer 31 and be located at respectively A bulge structure 33 and the B bulge structure 34 at external insulation layer 31 two ends, described A bulge structure 33 and B bulge structure 34 are stuck in the shell end outlet place of earplug 1 end and plug 2 ends, be provided with folding stretching structure 32 in described external insulation layer 31 stage casings, user in use can be by stretching or shrinking the length of freely adjusting earphone cord 3, while carrying, earphone cord 3 folding stretching structure 34 places are retracted to the shortest after, can reduce the folding of earphone cord 3, not only simple and convenient, and good looking appearance.

The described earphone core 35 that is positioned at 32 sections, folding stretching structure is spring-like screw arrangement, and two earphone cores 35 cross one another and spiral; Described earphone core 35 comprises wire 351 and inner insulating layer 352, and described inner insulating layer 352 adopts flax fiber material to make, and is tightly coated on wire 351 surfaces, to strengthen tensile property and the insulation property of earphone core 35; The A bulge structure 33 at described earphone cord 3 two ends and B bulge structure 34 be bonded in respectively in earplug 1 shell and plug 2 shells in, prevent the loosening effect in earphone cord 3 joints except reaching, also can play the effect of the shell end outlet place sealing of earplug 1 and plug 2.

Point line segment that common headphones line generally includes the total segment being connected with plug 2 and total segment is connected respectively with two earplugs.In the technical program, described folding stretching structure 32 is arranged in the bus of earphone cord 3, as shown in Figure 6, in the time using earphone, only plug 2 need be connected with audio frequency apparatus interface, can as required earphone cord 3 be stretched to Len req; After using, only the folding stretching structure 32 of earphone cord 3 need be shunk, can carry easily; Even if do not shrink, directly earphone cord 3 is folded up, because its external insulation layer 31 is similar to the structure of collapsible suction pipe, and the spring-like helical structure of earphone core 35, even if 180 ° of bendings also can easily complete, and internal-external all can not damage.

The foregoing is only preferred embodiment of the present utility model, the distortion identical with thinking of the present utility model and replacement all should be in protection ranges of the present utility model.
