Embodiment

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

See also Fig. 1, the utility model probe connector 1 comprises an insulating body 10, and insulating body 10 is assembled with at least one probe 20 and at least one second elastomer 30.

Insulating body 10 is rectangular-shaped, offers assembly hole 11 on it, and this insulating body 10 is run through in described assembly hole 11 front and back.Also offer assembling grove 12 on the insulating body 10, described assembling grove 12 is interconnected with this assembly hole 11.When assembly hole 11 when being a plurality of, then between two adjacent assembly holes 11, offer a described assembling grove 12, and this assembling grove 12 is communicated with respectively with the assembly hole 11 of its both sides.

See also Fig. 2, described probe 20 comprises a sleeve pipe 21, a

probe

22 and 1 first elastomer 23 respectively.

Described sleeve pipe 21 comprises a columned cylindrical shell 211 and one and the base 216 of described cylindrical shell 211 integrative-structures.The inside of cylindrical shell 211 offers a host cavity 212, and host cavity 212 forms an opening that is communicated with space outerpace 213 in the upper end of cylindrical shell 211.The lower end closed of cylindrical shell 211, and vertically offer a fluting 214 on the sidewall of cylindrical shell 211, this fluting 214 runs through the sidewall of cylindrical shell 211 and is communicated with described host cavity 212.The bottom of cylindrical shell 211 goes out to all boss and forms described base 216.

The columniform contact site 226 that described probe 22 has a columniform stop section 221 and extended to form by stop section 221 front ends.The bottom surface of this stop section 221 is an inclined-plane, and its diameter is greater than the diameter of the opening 213 of described sleeve pipe 21 front ends.The diameter of this contact site 226 stretches out sleeve pipe 21 less than the diameter of described opening 213 thereby this contact site 226 can see through described opening 213.During assembling, probe 22 is installed in the host cavity 212 of sleeve pipe 21 and can be free to slide in host cavity 212, and its contact site 226 can stretch out in sleeve pipe 21 outsides by this opening 213.

Described first elastomer 23 has one first end 231 and one and first end, 231 second opposed end 232, and this first elastomer 23 can produce an elastic force when described

first end

231 and 232 relative motions of second end.This first elastomer 23 is arranged in the host cavity 212 of sleeve pipe 21, and its first end 231 is connected to the diapire of host cavity 212, and its second end 232 is connected on the bottom surface of probe 22 stop section 221.Probe 22 contact site 226 is replaced by the elasticity of first elastomer 23 and is seen through opening 213 and stretch out in outside the

sleeve pipe

21, and 22 stop section 221 inlay cards of popping one's head in are in these opening 213 inboards.Described first elastomer 23 is a compression spring in the present embodiment.

Please consult Fig. 1 again, probe 20 is assembled in the assembly hole 11 of insulating body 10, and its base 216 exposes and electrically connects an electronic component (figure does not show) from assembly hole 11 1 ends of correspondence.The probe 22 of probe 20 stretches out insulating body 10 by the other end of assembly hole 11, supplies and another electronic component (figure does not show) butt.

Please continue and consult Fig. 1, second elastomer 30 that present embodiment adopted is a torsion spring, and this torsion spring has two elastic arms 31, and when this two elastic arm 31 compressed relatively, torsion spring produced an elastic-restoring force.The end of two elastic arms 31 is respectively to the curved top 32 that is bent to form of a side, the terminal holding section 33 that freely extends to form of this top 32.When assembling, this second elastomer 30 is arranged in the assembling grove 12 of insulating body 10, and the fluting 214 that the top 32 of its two elastic arm 31 sees through on the sleeve pipe 21 of described probe 20 respectively stretches in the host cavity 212 of an adjacent probe 20, its holding section 33 is held in respectively on the outer rim of corresponding fluting 214, excessively stretches into this host cavity 212 to prevent described top 32.

Described torsion spring only is a preferable selection of second elastomer 30 of the utility model probe connector 1, the scheme that other is equivalent, as fix elasticity bending element respectively at fluting 214 places of each probe 20, the part of its elasticity bending element is stretched in the host cavity 212 of probe 20, also can reach identical technique effect.

See also Fig. 3, when the contact site 226 of the probe 22 of the utility model probe connector 1 was pushed against downwards by an external force, probe 22 to lower slider, and compressed described first elastomer 23 along the inwall of sleeve pipe 21.Because 221 bottom surfaces, stop section of the probe 22 of present embodiment probe connector 1 are an inclined-plane, first elastomer 23 produces a bounce when being pressed down by this inclined-plane, the pushing and pressing effect of this bounce make probe 22 to lopsidedness and with the inwall butt of sleeve pipe 21.Along with probe 22 continuation to lower slider, the top 32 of described second elastomer 30 is touched in the bottom surface of the stop section 221 of probe 22, and compresses described top 32 laterally and affect the elastic arm 31 of this second elastomer 30.Second elastomer 30 promptly produces a bounce, the direction of this bounce is identical with the elastic force direction that described first elastomer 23 is produced, thereby strengthen the conflict power of probe 22 and sleeve pipe 21 inwalls, stablizing of the electric connection that further assurance the utility model probe connector 1 is realized effectively prevents the generation of hit phenomenon.

It is pointed out that the utility model be not the bottom surface that only is only applicable to pop one's head in be the probe on inclined-plane.As shown in Figure 4, in another embodiment of the present utility model, offer a groove 222 ' on the probe 22 ' bottom surface of probe connector 1 ', this groove 222 ' is in order to fix second end 232 ' of this first elastomer 23 '.This embodiment can reach the purpose of the electrical connection effect of strengthening the utility model probe connector equally.In addition, when the bottom surface of the probe of probe connector is designed for plane formula, also can reach technique effect of the present utility model equivalently.

In sum, the top 32 of second elastomer 30 of the utility model probe connector 1 is stretched in the host cavity 212 of probe 20 through the fluting 214 of sleeve pipe 21.When the probe 22 of probe 20 is pressed down by external force, will pop one's head in and 22 be resisted against on the inwall of sleeve pipe 21 to a side in the top 32 of described second elastomer 30, thereby reach the purpose that probe 22 and sleeve pipe 21 inwalls stablize butt, realize the effect that guarantees that electric connection is stable.

Above disclosed, only be preferred embodiment of the present utility model, do not use to limit interest field of the present utility model.Modify or variation as for other equivalence of the present utility model, all should be encompassed in the claim scope of the present utility model.
