When plug 200 is extracted electric connector 100, the far-end connecting portion 201 that is used for plug 200 is with the frictional force between strained locking bend 42 greater than locking bend 42 and the confining force that locks between recess 12, and what make that the locking bend 42 of holding device 4 moves and lock bend 42 outward with far-end connecting portion 201 is attached to the part that locks in recess 12 recess 12 that goes out of lock.Along with, holding device 4 continues to move outward, and curved portions 41 moves to bottom from the top of guide surface 11 gradually, and locking bend 42 returns to gradually original removable insulator 3 of state while and also is subject to the stopping of end wall of insulation shell 7 and stops mobile.simultaneously, in the process that removable insulator 3 moves away from fixed insulation body 1, two near-end splicing ears 203 and 204 bend 231 and 241 leave respectively slit 32 and 33 and enter into those widened sections 321 and 331, near-end splicing ear 23 and 24 returns to original free state gradually, near-end splicing ear 23 and 24 contact site also leave respectively near-end connecting portion 203 and 204, even if the far-end connecting portion 202 of plug 200 and 201 in the process that plug 200 is extracted through near-end splicing ear 23 and 24 o'clock, far-end connecting portion 202 does not contact with 24 with near-end splicing ear 23 with 201 yet, thereby reduced the friction to near-end splicing ear 203 and 204.Like this, when plug 200 was extracted electric connector 100 fully, the internal structure of electric connector 100 returned to again the initial condition shown in Figure 14-16.
Plug described in the utility model can be in use to need the audio jack that repeatedly plugs, and for example the headset plug of 3.5 millimeters, phono connector, can be the plug with 4 electrical contacts, the plug with 3 electrical contacts etc.
, according to the electric connector of above-mentioned various embodiment of the present utility model,, by guide hump is set, can guide removable insulator to move in insulation shell, thereby change the operating state of some splicing ears.Further, in the part process that plug inserts in electric connector and the removable insulator of plug promotion moves, namely at the far-end splicing ear with before plug far-end connecting portion is electrically connected to, the near-end splicing ear of fixed insulation body does not contact with any connecting portion of plug, until inserting, plug puts in place, be the far-end splicing ear with after the far-end connecting portion is electrically connected to, the near-end splicing ear just contacts with the near-end connecting portion of plug.Similarly, in the part process that pulls the plug out of the socket, after the far-end splicing ear left the electrical connection of far-end connecting portion, the near-end splicing ear of fixed insulation body did not contact with any connecting portion of plug yet.Shorten thus the contact path of near-end splicing ear with plug, reduced the friction to the near-end splicing ear, extended the life-span of near-end splicing ear.
It will be appreciated by those skilled in the art that, embodiment described above is exemplary, and those skilled in the art can make improvements, structure described in various embodiment in the situation that not the conflict aspect recurring structure or principle can carry out independent assortment, thereby on the basis that solves technical problem of the present utility model, realize more kinds of electric connectors.
