Fig. 2 is the enlarged drawing that Fig. 1 preventing plug from dropping falls the part A of formula earphone cord.
The front view that the preventing plug from dropping that Fig. 3 is Fig. 1 falls the plug of formula earphone cord and wire body connects.
Fig. 4 is the front view that Fig. 1 preventing plug from dropping falls the bared end of formula earphone cord.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
With reference to 1-Fig. 4 of figure, a kind of preventing plug from dropping falls formula earphone cord, including wire body 1, plug 2, capsul 3 and reinforcing block 4.
Plug 2 includes bared end 21 and connection end 22, and bared end 21 is integrally formed with connection end 22, and bared end 21 is located at
The lower section of connection end 22.Connection end 22 is connected with wire body 1, and the middle part of connection end 22 is provided with projection 20, and projection 20 can be two,
It is symmetricly set on connection end 22, projection 20 is oblique, and raised 20 highest one end are towards bared end 21, and raised 20 highests
The distance on one end to the surface of connection end 22 be 0.20mm -0.25mm.
On the other hand, bared end 21 includes L channel section 211, R channel section 212, microphone section 213 and ground connection section 214.
