Abstract

Disclosed is a wire cable connector (100) which comprises a plug (1), a wire cable (2) electrically connected with the plug, a stress releasing portion (4) sleeved outside the wire cable, an inner shell (5) sleeved on the stress releasing portion and in threaded connection with the plug, and an outer shell (6) sleeved outside the inner shell and in threaded connection with the plug. The stress releasing portion is pasted to the inner shell, and when being rotated, the inner shell drives the stress releasing portion to move in the front-back direction, the inner shell moves backwards to protect a repeatedly-bent contact position of the wire cable and the stress releasing portion in the stress releasing portion, so that the circumstance that the wire cable connector cannot be used due to the fact that a joint is thoroughly damaged is avoided, and service life of the wire cable connector is prolonged.

Description

Wire and cable connector

[technical field]

The invention relates to a kind of wire and cable connector, relate in particular to a kind of wire and cable connector of transmission of audio signal.

[background technology]

Chinese patent has disclosed a kind of wire and cable connector No. CN101599593A, the cable that it comprises the plug that is electrically connected electronic equipment, be electrically connected with plug, be coated on plug outer fixing pipe, flexible sleeve and be coated on the outer group of fixing pipe and take over body, flexible sleeve is coated on cable, this class wire and cable connector is used for a long time, can damage its junction due to the repeatedly bending of flexible sleeve and cable, can't use very unfortunate in the intact situation of other parts of wire and cable connector.

Therefore need a kind of improved wire and cable connector to overcome the deficiencies in the prior art.

[summary of the invention]

Main purpose of the present invention is to provide a kind of wire and cable connector increased the service life.

For reaching above-mentioned purpose, the present invention can adopt following technical scheme: a kind of wire and cable connector, the cable that it comprises plug, be electrically connected with described plug, be sheathed on the outer Stress Release section of described cable, the inner casing that is sheathed on described Stress Release section and is threaded with described plug, the shell that is sheathed on described inner casing and is threaded with described plug, described Stress Release section affixes to described inner casing, when rotation during described inner casing, described inner casing drives described Stress Release section and moves up in front and back.

Compared with prior art; the advantage of wire and cable connector of the present invention is: inner casing moves backward; the contact position that cable and Stress Release section are repeatedly bent is protected in Stress Release section; avoid junction thoroughly to damage wire and cable connector can't be used, thereby extended the useful life of wire and cable connector.

[embodiment]

Please refer to Fig. 1 to Fig. 5, wire and cable connector 100 of the present invention is an audio jack, for connecting all kinds of electronic equipment audio signals.Wire and cable connector 100 comprises a plug 1, cable 2, inner module 3, Stress Release section 4, inner casing 5 and shell 6.Wherein, the rear end of plug 1 and cable 2 front ends are electrically connected, plug 1 front end is connected with electronic equipment, inner module 3 takes shape in the junction of plug 1 rear end and cable 2 front ends, Stress Release section 4 is sheathed on outside cable 2, inner casing 5 is sheathed on the outer surface of inner module 3, and shell 6 is sheathed on the outer surface of inner casing 5 front ends.

It is stepped with the second external thread part 12, the first external thread parts 11 and the second external thread part 12 that are positioned at the first external thread part 11 rear ends that plug 1 is provided with the first external thread part 11, and the first external thread part 11 diameters are greater than the diameter of the second external thread part 12.

Inner module 3 is tubulose, and it coats the junction of plug 1 and cable 2.Stress Release section 4 is cylindric, and it is provided with and is positioned at front end and outwards protrudes out the butting section 41 of formation from outer circle wall.

Inner casing 5 is sheathed on Stress Release section 4 and is threaded with plug 1.Inner casing 5 be the front and back external diameter do not wait cylindric, the external diameter that is provided with the first cylindrical portion 51 that is positioned at its front portion and is positioned at second cylindrical portion 52, the first cylindrical portion 51 at its rear portion is greater than the external diameter of the second cylindrical portion 52.Wherein the first cylindrical portion 51 is provided with the second internal thread part 511 that is positioned at its inner peripheral wall, the second internal thread part 511 matches with the second external thread part 12, the second cylindrical portion 52 ends are provided with and are protruded out the holding section 521 formed by inner peripheral wall to axis direction, Stress Release section 4 can pass inner casing 5 from front to back, when 41Yu holding section, butting section 521 contacts, 4, Stress Release section can't further move backward.

Shell 6 is sheathed on inner casing 5 and is threaded with plug 1.Shell 6 is also cylindric, and its front portion is provided with the first internal thread part 61 that is positioned at inner peripheral wall, and wherein the first internal thread part 61 matches with the first external thread part 11.

During assembling, after plug 1 and cable 2 are welded, inner module 3 is overmolded in the rear end of plug 1, the front end of cable 2 and the junction of plug 1 and cable 2.Stress Release section 4 is sheathed on to cable 2, and butting section 41 is positioned at the front end of cable 2.Inner casing 5 turns clockwise from back to front and is threaded io plug 1, and be sheathed on outside Stress Release section 4, holding section 521 is fastened in rear of butting section 41 glue both is bonded together, Stress Release section 4 and inner casing 5 are secured together, when rotary inner casing 5, inner casing 5 drives Stress Release section 4 and moves up in front and back.The second internal thread part 511 matches with the second external thread part 12, finally shell 6 is turned clockwise from back to front and is threaded io plug 1, and the first internal thread part 61 of shell 6 front portions matches with the first external thread part 11, and rear sleeve is located at inner casing 5.So far, wire and cable connector 100 assemblings are complete.

Because long-time cable 2 and the contact position of Stress Release section 4 rear ends of using repeatedly bent and easily damage, inner casing 5 is rotated counterclockwise backward and moves simultaneously with Stress Release section 4, the impaired part of cable 2 is moved in Stress Release section 4, just extended the useful life of wire and cable connector 100 like this, if cable 2 damages again with the junction of Stress Release section 4, the impaired part of cable 2 can be moved on in Stress Release section 4 again, the life-span of wire and cable connector 100 extends again, by that analogy, inner casing 5 moves backward until the first cylindrical portion 51 leans with the end of shell 6, inner casing 5 can't move backward.
