Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to FIG. 1 and FIG. 2 , the audio socket connector 30 of the present invention includes an insulating body 31 and a plurality of probe terminals 32 .

Please refer to FIG. 2 , the insulating body 31 has a substantially rectangular base 311 . Near the upper side of the base 311 is defined a substantially cylindrical insertion slot 312 passing through the base 311 left and right. The base body 311 defines a plurality of cylindrical locking grooves 313 extending to the lower surface and communicating with the insertion grooves 312 .

Please refer to FIG. 2 and FIG. 3 , the probe terminal 32 includes a metal sleeve 321 , a metal probe 322 and an elastic body 323 . The metal sleeve 321 has a cylindrical shell 3211 , one end of the shell 3211 shrinks inwardly to form an annular stop portion 3213 , and the stop portion 3213 has an opening 3214 . The other end of the housing 3211 is connected to a closed base 3212 , and one end of the base 3212 forms a welding portion 3215 . The metal probe 322 has a cylindrical sliding portion 3221 and a cylindrical contact portion 3222 protruding upward from the sliding portion 3221 . The bottom end of the sliding portion 3221 is recessed to form a cylindrical cavity 3223 . The sliding part 3221 is installed in the housing 3211 of the metal sleeve 321, and the diameter of the sliding part 3221 is larger than the diameter of the opening 3214 so that the sliding part 3221 is stuck in the housing 3211; the diameter of the contact part 3222 is smaller than the diameter of the opening 3214 The contact portion 3222 protrudes out of the metal sleeve 321 through the opening 3214 of the metal sleeve 321 . The elastic body 323 is accommodated in the casing 3211 of the metal sleeve 321 , one end of which is in contact with the bottom surface of the cavity 3223 , and the other end is in contact with the bottom surface of the base 3212 . The metal sleeves 321 of the probe terminals 32 are held and accommodated in the holding grooves 313 of the insulating body 31 in an integral molding manner, and the metal probes 322 of the probe terminals 32 can be movably protruded from the holding grooves 313 and inserted into the socket. Inside the groove 312.

Please refer to Fig. 4, when a plug connector 40 is inserted into the audio socket connector 30 of the present invention, the plug connector 40 has a metal plug 41, and the metal plug 41 is inserted into the insulating body 31 of the audio socket connector 30. In the insertion groove 312, since the metal probe 322 of the probe terminal 32 protrudes from the holding groove 313 and enters the insertion groove 312, the metal plug 41 presses the metal probe 322 into the metal sleeve 321 during the insertion process, and the metal The probe 322 compresses the elastic body 323 and the elastic body 323 provides an upward elastic force, so that the metal probe 322 forms a pressing force against the metal plug 41 to firmly resist the metal plug 41 .

As mentioned above, the audio jack connector 30 of the present utility model uses the probe terminal 32 instead of the existing shrapnel type connection terminal, which not only can maintain long-term stable and reliable performance, but even after long-term use, the probe terminal 32 can still maintain the connection to the plug. The effective pressing of the device 40 ensures the electrical connection between the audio jack connector 30 and the plug connector 40; moreover, the design and manufacture of the audio jack connector 30 are more convenient.

The utility model is not limited to the above-mentioned specific embodiments, and those familiar with the technical field can also make various changes accordingly, such as the clamping groove can be selected at any angle according to requirements, and these changes should be covered in the claims of the utility model In the range.
