Description

Cable-assembly

[technical field]

The present invention relates to a kind of cable-assembly with structure of protection cable.

[background technology]

At present, the various portable electric appts such as notebook computer, projecting apparatus and player have obtained extensively popularizing and using, and above-mentioned electronic equipment often is carried at one's side or needs mobile.When carrying or move, for the ease of taking and placing, often the cable on the electronic equipment is drawn in together, like this, cable will be bent.Therefore need a structure or device is protected cable and it is not damaged, and then improve the useful life of described cable.At existing cable front end, generally all form a stress relief element.When cable was subject to excessive bending power, the angle that this stress relief element can protect cable to bend can be not too small, reduced the risk that cable is fractureed.This stress relief element has the effect that really can protect cable; but the miniaturization along with electronic equipment; the size of cable and stress relief element is restricted so; if the too much size that reduces stress relief element; stress relief element is too small, excessively thin or too short so; when being subject to the bending of certain angle, may cause stress relief element, cable to be fractureed together, stress relief element can not play a very good protection.

Therefore, when the cable of some moulding stress releasing members can not satisfy the demand of small-scale structure electronic product at present, be necessary to provide a kind of cable-assembly to overcome the problems referred to above.

[summary of the invention]

Main purpose of the present invention is to provide a kind of cable-assembly of not frangible lines cable.

For achieving the above object, the present invention can adopt following technical scheme: a kind of cable-assembly, it comprises a spring, pass cable in described spring, with the connector that described cable is electrically connected, described spring one end is fixed on the described connector, the other end exposes to described connector.

Compared with prior art, the beneficial effect of cable-assembly of the present invention is: according to the toughness of spring, well the bending angle of control line cable assembly protects cable not fractureed.

[embodiment]

Please refer to Fig. 1 to shown in Figure 4, cable-assembly 100 of the present invention comprises a connector 1, the cable 5 that is connected with connector 1 and is positioned at the spring 6 of cable 5 outer surfaces.

In the present embodiment, cable-assembly 100 is earphone cord, and connector 1 is audio plug connector, it comprises plug 10, be installed on the inner module 2 of plug 10 rear ends, be positioned at inner module 2 rears bonnet 3, coat the shell 4 of inner module 2.

Plug 10 comprises insulator 12 between some Metal Contact section 11, the Metal Contact section 11, at the connecting portion 13 of its rear end, between Metal Contact section 11 and connecting portion 13, have a flange 14.

Bonnet 3 is for plastic rubber shaping forms, and it comprises the host side 31 that is positioned at front end, the accepting hole 33 that is positioned at the blind end 32 at 31 rears, host side and runs through host side 31 and blind end 32.Host side 31 and blind end 32 are cylindrical, and the diameter of host side 31 is less than the diameter of blind end 32.Host side 31 is provided with a support slot 311 that is recessed to form backward from its front surface.

The cylindrical structural that shell 4 forms for plastic rubber shaping.Shell 4 has the through hole 41 that runs through its front and rear surfaces and the accepting groove 42 that is recessed to form forward from its rear end.Through hole 41 and accepting groove 42 concentric cylindrical, the diameter of accepting groove 42 is greater than the diameter of through hole 41.

Spring 6 is a horn-like structure, and the diameter of its front end is less than the diameter of rear end.For ease of introducing technical scheme of the present invention, cable along the line 5 axle center are defined as X-axis, the axle vertical with X-axis is Y-axis.As shown in Figure 3, spring 6 is arranged in the coordinate system of one of them XOY of the coordinate system of several XOY.The diameter of the leading portion of spring 6 identical (Y value of spring 6 is identical), the leading portion of spring 6 coats cable 5, along with the axis direction (X-axis) of spring 6 cables 5 along the line extends back, spring 6 is from a certain X value, the diameter of spring 6 (Y value of spring 6) increases gradually, and so, cable 5 just is contained in the back segment of spring 6, the back segment of spring 6 does not coat cable 5, and the rear end of spring 6 forms the space of reversing of cable 5.In the coordinate system of XOY, spring 6 is from a certain X value, and the peripheral profile of spring 6 is a circular arc shape.

When assembling, the wire of cable 5 (not shown) is electrically connected with the connecting portion 13 of connector 1, and inner module 2 takes shape on the connecting portion 13, and the outer surface of inner module 2 is mutually concordant with the outer surface of flange 14.

Shell 4 coats the flange 14 and inner module 2 of connector 1, and the host side 31 of bonnet 3 is contained in the accepting groove 42, and both can be by the fixing connection of mode of some glue or interference fit.Spring 6 is contained in accepting hole 33, and in the support slot that is fastened in foremost bonnet 3 311 of spring 6, the front surface of the blind end 32 of bonnet 3 is against the rear surface of shell 4.

During the axis direction (X-axis) of spring 6 cables 5 along the line extended back, the width between the adjacent cable that is exposed to spring 65 increased gradually.

The present invention uses the stress relief element of spring 6 alternative prior aries, the drawback that avoided easily breakage of stress relief element, fractures.Simultaneously, the angle of spring 6 rear ends and cable 5 increases, and is conducive to the angle that cable more can improve bending.
