The technical scheme that technical problem adopted that the utility model solution prior art is difficult to locate with poor stability provides a kind of high stable precision-fit type audio connector, comprises connector body and structural member; Described main body comprises socket and grafting chamber and neck therebetween again; Described structural member comprises the inverted U-shaped stator that cooperates with described neck again; Its middle part is provided with the public contact site of bending; At least one end of described structural member is provided with outstanding ground wire weld tabs; Particularly the two sides of described neck respectively are provided with a padlock sloping platform; The two side arms of described inverted U-shaped stator respectively is provided with a snap close with described sloping platform adapted.
According to a preferred embodiment of the present utility model, the middle part of described neck is provided with the prominent bar of at least one prestressing force.
According to a preferred embodiment of the present utility model, the projecting height of described prominent bar is 0.3 to 0.8 times of described stator thickness.
According to a preferred embodiment of the present utility model, the afterbody in described connector body grafting chamber is provided with dust cover.
According to a preferred embodiment of the present utility model, described cover plate is provided with a plurality of dead bolts; The tail wall in described grafting chamber is provided with the lockhole with described dead bolt adapted.
According to a preferred embodiment of the present utility model, described structural member comprises that signal switches the shell fragment group; This signal switches shell fragment group and comprises that not only first contact flat spring links to each other with far-end with it but also keeps the reinforcement shell fragment of certain distance; Be provided with stator at described first contact flat spring by center, grafting chamber one side; This first contact flat spring and stator are normally off.
According to a preferred embodiment of the present utility model, the punching press from its parent member of described reinforcement shell fragment system forms, and belongs to same parent member with described first contact flat spring, and both smoothly link to each other at this parent member far-end.
According to a preferred embodiment of the present utility model, described reinforcement shell fragment is with the grafting displacement of the primary clearance between described first contact flat spring less than described first contact flat spring.
The beneficial effects of the utility model are: adopt the measure of the prominent bar of powerful snap close and prestressing force, make the most loosening ground wire contact site of audio connector firmly be fixed in the connector neck exactly, can not become flexible because of plugging repeatedly; After simultaneously fastening in advance, loosening when avoiding welding.In addition, dust cover can reduce laying dust and scruff; The reinforcement shell fragment also makes the contact engaging and separating force of plugs and sockets and reliability strengthen greatly.

[embodiment]
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1 to Fig. 5.
The utility model is a kind of high stable precision-fit type audio connector, comprises connector body 10 and structural member 20; Described main body 10 comprises socket 19 and grafting chamber 18 and neck therebetween again; Described structural member 20 comprises the inverted U-shaped stator 21 that cooperates with described neck again; Its middle part is provided with the public contact site 212 of bending; Described structural member 20 at least one ends are provided with outstanding ground wire weld tabs 213; Particularly the two sides of described neck respectively are provided with padlock sloping platform 11; The two side arms of described inverted U-shaped stator 21 respectively is provided with a snap close 211 with described sloping platform 11 adapteds.During assembling, to pressing down, allow snap close fasten described sloping platform, finish the fastening type assembling from described neck top.Also can detain earlier on one side, detain another side again.
The middle part of described neck is provided with the prominent bar 12 of at least one prestressing force.Its projecting height is 0.3 to 0.8 times of described stator 21 thickness.Rigidity and elasticity that prominent bar has utilized the metal stator are set, make snap close fasten described sloping platform before, need apply prestressing force and just can finish the fastening type assembling, so reliability is higher.
The afterbody in described connector body 10 grafting chambeies 18 is provided with dust cover 23.
