Embodiment
Consult Fig. 3, preferable the executing of the utility model provides a kind of electric connector socket in the example, and it comprises: an insulating base 100, a tongue piece 200, a detection terminal 300 and a shell 400.
The pedestal that insulating base 100 is preferably processed for plastic cement, it comprises a stop surface 110.Tongue piece 200 is that a plastic cement is dull and stereotyped, and it stretches out from the stop surface 110 vertical stop surfaces 110 of insulating base 100, and tongue piece 200 comprises a sidewall 210, and sidewall 210 vertical stop surfaces 110 stretch out from stop surface 110.
Consult Fig. 4 to Fig. 6, detection terminal 300 is a punching press and the long-bar metal sheet that is bent into, preferably processes (but the utility model is not limited thereto) for phosphor bronze, and it comprises a stiff end 310, an elastic arm 320, a contact-segment 330.Stiff end 310 preferably comprises vertically section 311, one traversing section 312 and a bending segment 313, and in present embodiment, preferably vertically section 311 is embedded in the insulating base 100 and whole detection terminal 300 is fixed in the insulating base 100, but and the elasticity activity; Vertically section 311 passes from the outer place of stop surface 110 upper side walls 210, passes back bending 90 degree and forms traversing section 312 towards extending away from the direction of sidewall 210 along stop surface 110; Traversing section 312 is along stretching and bending and be the bending segment 313 of circular arc.Elastic arm 320 is preferably from the bending segment 313 curved extensions of stiff end 310; Bending segment 313 connects elastic arm 320 and traversing section 312; Bending segment 313 is smooth-going the connection with elastic arm 320, and its junction two arcs are tangent, and the arcuate directions that elastic arm 320 extends is recessed to sidewall 210; Contact-segment 330 is from elastic arm 320 curved extensions and continuous with elastic arm 320 curvature, and the arcuate directions of contact-segment 330 is protruding in sidewall 210; Lead segment 340 is from contact-segment 330 straight-line extensions and continuous with contact-segment 330 curvature, and its bearing of trend is away from sidewall 210 and away from stop surface 110, so lead segment 340 has an angle with sidewall 210.
Consult Fig. 3 and Fig. 7, shell 400 is the tubular of both ends open for the sheet metal bending forms, and a wherein end of shell 400 is sheathed on insulating base 100 and makes it around tongue piece 200.Shell 400 preferably comprises a start hole 410, start hole 410 be opened on the shell 400 and its position corresponding with detection terminal 300,340 1 sections of elastic arm 320 to the lead segment of start hole 410 corresponding detection terminals 300 preferably.
Consult Fig. 8; The electric connector socket of the utility model; The corresponding electrical connector plug that is applied to peg graft, electrical connector plug has an iron-clad 21, and tongue piece 200 profiles conform in the inboard shape of iron-clad 21 and the utility model; When the electric connector socket of electrical connector plug grafting the utility model, iron-clad 21 is placed in outside the tongue piece 200.
When iron-clad 21 inserts the electric connector socket of this wound; Lead segment 340 just can be guided iron-clad 21 and slip between detection terminal 300 and the sidewall 210; Make iron-clad 21 promote contact-segments 330 and elastic arm 320 outwards strutted that elastic arm 320 to the lead segment of detection terminal 300 is just passed to start hole 410 by iron-clad 21 for 340 1 sections.Because elastic arm 320 is an arc, it makes to have a start gap 420 between iron-clad 21 and elastic arm 320 and the bending segment 313 after being passed by iron-clad 21, so iron-clad 21 just can not be urged to the structure of detection terminal 300 and make it impaired.The utility model need not change original material, through improved arc elastic arm 320, uses straight elastic arm 12 compared to prior art, and the bending segment 313 bending angles of the utility model are less, therefore can be when not making the metal folding angle excessive and subdue.Moreover when iron-clad 21 promoted elastic arm 320, stress can be scattered on the elastic arm 320 of arc, can not concentrate on bending segment 313 and make bending segment 313 fatigues cause permanent deformation by stress.
Certainly; The utility model also can have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
