Embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.

See also Fig. 1 and Fig. 2, the utility model audio socket connector 30 comprises an insulating body 31 and some probe terminals 32.

See also Fig. 2, insulating body 31 has a matrix 311 that roughly is rectangular bulk, and matrix 311 offers about one near the upside places and runs through matrix 311 and roughly cylindrical inserting groove 312.Offer some columniform support slots 313 that extend to lower surface and be communicated with on the matrix 311 with inserting groove 312.

See also Fig. 2 and Fig. 3, probe terminal 32 comprises a metal sleeve 321, a metal probe 322 and an elastomer 323.Metal sleeve 321 has a cylindrical circular housing 3211, and an end of this housing 3211 inwardly shrinks the stopper section 3213 that is formed with an annular, and stopper section 3213 has an opening 3214.The other end of housing 3211 is connected with the base 3212 of a sealing, and an end of this base 3212 forms weld part 3215.Metal probe 322 has a cylindrical sliding part 3221 and by the sliding part 3221 convex cylindrical contact sites 3222 that stretch out, and sliding part 3221 bottoms set to the concave and form a columniform cavity 3223.Sliding part 3221 is installed in the housing 3211 of metal sleeve 321, and the diameter of sliding part 3221 greater than the diameter of opening 3214 so that sliding part 3221 be fastened in the housing 3211; The diameter of contact site 3222 less than the diameter of opening 3214 so that contact site 3222 passes the opening 3214 of metal sleeve 321 stretches out outside the metal sleeve 321.Elastomer 323 is contained in the housing 3211 of metal sleeve 321, and the one end contacts on the bottom surface of cavity 3223, and the other end contacts on the bottom surface of base 3212.The metal sleeve 321 of probe terminal 32 holds in the support slot 313 that is contained in insulating body 31 in one-body molded mode respectively, and the metal probe 322 of probe terminal 32 stretches out in support slot 313 movably and enters in the inserting groove 312.
