Specific embodiment
Refer to shown in Fig. 1 to Fig. 4, Fig. 1 is the cable 100 of the present invention, it includes inner part 1, and inner part 1 includes first
Section 11 and second segment 12 (see Fig. 4).Cable 100 also includes wrapping up the first paragraph 11 of inner part 1 by way of injection mo(u)lding
Second rubber section 2, wrapped up by way of injection mo(u)lding internal 1 second segment 12 the first rubber section 3, the first rubber section 3
Including the Part I 31 being molded respectively by injection molding twice and Part II 32.Part I 31 and second
Points 32 internally part 1 week to be upwardly into small part not overlapping.Technical solution of the present invention can make cable 100 surface manufacturing
Do not leave a blemish on, do not destroy the overall appearance of cable.
The abutting end of the first rubber section 3 and the second rubber section 2 partly overlaps, and is arranged such, after moulding, the first rubber
Glue portion 3 and the second rubber section 2 can be very good to link together.
In the present embodiment, the first rubber section 3 and the second rubber section 2 are cylinder, and the diameter of the first rubber section 3 is big
Diameter in the second rubber section 2.Inner part 1 is cylinder, and inner part 1, the first rubber section 3 and the second rubber section 2 are coaxial.
Refer to shown in Fig. 3 and Fig. 4, Part I 31 is provided with the extension 311 and first extending into Part II 32
Groove 312；The extension (not shown) that Part II 32 is provided with the first groove 312 extending into Part I 31 and confession extend
The second groove (not shown) that portion 311 extends.
In the present embodiment, the extension 311 of Part I 31 is one, in other embodiments, extension 311
Can at least two.
Part II 32 includes second groove of at least two and extension 311 cooperation of Part I 31.Part I
31 extension 311 and the first groove 312 are with the central shaft centrosymmetry of inner part 1.
In the present embodiment, cable 100 can be earphone cord, coiled handset cord or usb data wire.
The invention also discloses a kind of method manufacturing cable 100, refer to shown in Fig. 2 and Fig. 5, the 3rd mould 200 wraps
Include mould 4 and lower mould 5, after matched moulds, inject rubber, mold first assembly 101.First assembly 101 includes inner part 1 and bag
It is rolled in the second rubber section 2 on inner part 1.
Refer to shown in Fig. 3, Fig. 6 and Fig. 7, the first mould 300 includes mould (6,7) and lower mould 8, by first assembly
