Abstract

The utility model discloses a kind of handset earphone line, part fork earphone cord on the left side by main earphone cord with by what extend in described main earphone cord, part fork earphone cord on the right side and form, described main earphone cord comprises rubber layer and is coated on four enamel covered wires in described rubber layer and two aramid fiber cores are formed; Described part fork earphone cord on the left side and part fork earphone cord on the right side form by rubber layer and two enamel covered wires be coated in described rubber layer and an aramid fiber core.The utility model is when ensureing that enamel covered wire wire diameter is constant, four enamel covered wires and two Kev bracing wires are provided with in main earphone cord, and formation two enamel covered wires and a Kev bracing wire form a furcation area earphone cord after earphone cord bifurcated, utilize two enamel covered wires and a Kev bracing wire stranded, after making bifurcated, the wire diameter of core is 1.0mm, and ensures stability and the tensile resistence of earphone cord Signal transmissions.

Description

A kind of handset earphone line

Technical field:

The utility model relates to a kind of handset earphone line, and what be specifically related to is the handset earphone line that a kind of wire diameter is little, tensile resistence is strong.

Background technology:

Handset earphone line general is in the market enamelled wire coppered wire, and with the outer quilt of TPE extrusion, wire diameter is 2.8mm, after bifurcated left and right acoustic channels each one, wire diameter is 1.4mm.And along with client's demand for experience more and more less to wire diameter, it is also proposed higher requirement to high-end earphone cord, after its bifurcated, wire diameter needs to reach 1.0mm, but also will ensure stability and the tensile resistence of earphone cord Signal transmissions.

Summary of the invention:

For this reason, the purpose of this utility model is to provide the handset earphone line that a kind of wire diameter is little, tensile resistence is strong.

For achieving the above object, the utility model mainly adopts following technical scheme:

A kind of handset earphone line, part fork earphone cord on the left side by main earphone cord with by what extend in described main earphone cord, part fork earphone cord on the right side and form, described main earphone cord is by rubber layer and be coated on four enamel covered wires in described rubber layer and two aramid fiber cores are formed; Described part fork earphone cord on the left side and part fork earphone cord on the right side form by rubber layer and two enamel covered wires be coated in described rubber layer and an aramid fiber core.

Further, described main earphone cord and described parting on the left side are pitched earphone cord, are parted on the right side and pitch earphone cord crotch and be provided with Y connection.

Further, the Kev bracing wire that described aramid fiber core is intensity is 21g/d, elongation is 3.6%.

Further, described rubber layer is that thermoplastic elastic material is made.

The utility model is when ensureing that enamel covered wire wire diameter is constant, four enamel covered wires and two Kev bracing wires are provided with in main earphone cord, and formation two enamel covered wires and a Kev bracing wire form a furcation area earphone cord after earphone cord bifurcated, utilize two enamel covered wires and a Kev bracing wire stranded, after making bifurcated, the wire diameter of core is 1.0mm, and ensures stability and the tensile resistence of earphone cord Signal transmissions.

Accompanying drawing illustrates:

Fig. 1 is the structural representation of the utility model handset earphone line;

Fig. 2 is A-A cutaway view in Fig. 1;

Fig. 3 is B-B cutaway view in Fig. 1;

Fig. 4 is C-C cutaway view in Fig. 1.

Identifier declaration in figure: main earphone cord 10, rubber layer 11, enamel covered wire 12, aramid fiber core 13, part on the left side fork earphone cord 20, part on the right side fork earphone cord 30, Y connection 40.

Embodiment:

For setting forth thought of the present utility model and object, below in conjunction with the drawings and specific embodiments, the utility model is described further.

Refer to shown in Fig. 1 ~ Fig. 4, Fig. 1 is the structural representation of the utility model handset earphone line; Fig. 2 is A-A cutaway view in Fig. 1; Fig. 3 is B-B cutaway view in Fig. 1; Fig. 4 is C-C cutaway view in Fig. 1.The utility model provides the handset earphone line that a kind of wire diameter is little, tensile resistence is strong.When it is less mainly for current handset earphone line wire diameter, the problem of tensile resistence and less stable.

The utility model includes main earphone cord 10 and the bifurcated earphone cord 20 that extended out by this main earphone cord 10 and part fork earphone cord 30 on the right side, is connected with between bifurcated earphone cord at main earphone cord 10 by Y connection 40.

Wherein main earphone cord 10 mainly includes and is positioned at outer field rubber layer 11, thermoplastic elastic material (TPE) is preferably in the present embodiment, and be positioned at four enamel covered wires 12 and two aramid fiber cores 13 (Kev draws) of rubber layer 11 inside, and described four enamel covered wires 12 and two aramid fiber cores 13 twist together (see Fig. 2).

Part fork earphone cord 20 on the left side the same with parting fork earphone cord 30 on the right side, it is all form (see Fig. 3, Fig. 4) with two enamel covered wires 12 and an aramid fiber core 13 (Kev draws) being positioned at internal layer by being positioned at outer field rubber layer 11.

Part fork earphone cord 20 herein on the left side and part fork earphone cord 30 on the right side and be actually two branch lines separated by a main earphone cord 10, because its line inside have employed a Gen Kaifula and two enamel covered wire combination, and Kev tensile strength be 21g/d, elongation is 3.6%, it has good stability, it is little to take up room, therefore, it is possible to meet, handset earphone line wire diameter is little, tensile resistence strong and the requirement of good stability.

More than that a kind of handset earphone line provided by the utility model is described in detail, apply specific case herein to set forth structural principle of the present utility model and execution mode, above embodiment just understands method of the present utility model and core concept thereof for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
