D4, a diameter of D of equal diameter section 3025, and D3≤D1<D4≤D2, D5=D3.When not being squeezed, boss 502 and positioning section 402
Not contacting, when extruding module 6 and extruding anticreep pad 5, boss 502 contacts with positioning section 402 and carries out positioning section 402
Extruding, makes contact pin 4 fix, during positioning section 402 is extruded by anticreep pad 5, provides axial extruding to contact pin 4
Power so that contact pin 4 fixing relatively stable.
Further, anticreep pad 5 uses elastomeric material to make, and during anticreep pad 5 is extruded, anticreep pad 5 is subject to
The extruding force of extruding module 6 and the extruding force of conical section 301 sidewall, produce micro-strain, and contact location with positioning section 402
Section 402 produces extruding, makes contact pin 4 fix.
Further, boss 502 is provided with the breach 503 connected with trepanning 504, and breach 503 is from one end of boss 502
Offer the other end to boss 502, anticreep pad 5 be squeezed the extruding force of module 6 move time, boss 502 is at conical section 301
Sidewall extruding force effect under, breach 503 starts deformation, shrinks, thus boss 502 contacts with positioning section 402, it is achieved right
Fixing of contact pin 4.
Further, according to the anticreep pad 5 loading characteristic when being squeezed, the width of breach 503 is from the end face of boss 502
The one end being connected with shim body 501 to boss 502 is gradually reduced, the width of breach 503 from the outer wall of boss 502 to trepanning
The hole wall direction of 504 is gradually reduced.
It addition, in the present embodiment, the outer wall of the inserting section 403 of contact pin 4 also sets up draw-in groove, spliced eye 303 with card
The aperture of the position that groove is corresponding is more than the aperture of other positions, and is provided with card in the position that spliced eye 303 is corresponding with draw-in groove
Spring, the inserting section 403 of contact pin 4 is fixed in spliced eye 403 by jump ring and card slot fit.
As it is shown in fig. 7, this utility model embodiment additionally provides a kind of train adapter, including such as two of Fig. 2 and Fig. 3
Plug connector, and the inserting section 703 of the contact pin 7 of a plug connector extend axially outwardly formation connecting portion 7031, another grafting
The inserting section 403 of the contact pin 4 of part is provided with the connecting hole 4031 coordinated with connecting portion vertically, when connecting, only need to squeeze using
Contact pin 4 and contact pin 7 are fixed by die block 6 respectively, then by the connection of the connecting portion 7031 of a contact pin 7 with another contact pin 4
Hole 4031 coordinates, and can realize the connection of adapter.
During use, extruding module can be threaded connection with the outer wall of wiring section, it is simple to compression and the disengagement to contact pin.
In sum, a kind of train adapter of this utility model embodiment offer and plug connector thereof, anticreep pad is being subject to
During extruding module extruding, anticreep pad gradually moves along the hole wall of the conical section in hole, location to adapter closure, anticreep pad
Simultaneously by the extruding force of hole wall of conical section, starting deformation, shrink, barbed portion is gradually reduced, and compresses contact pin；Meanwhile, by
It is inserted into position in contact pin group, can't move with anticreep pad, so that with anticreep pad to the movement of adapter closure, gradually
Axial stable contact force is provided for contact pin.Boss distance of distance contact pin positioning section when not pressurized also defines contact pin simultaneously
Axially-movable, it is ensured that do not resulted in run-bake-needle fault by severe impact.Contact pin can compressed, while preventing run-bake-needle fault, carry for contact pin
For the axial compression power that lasting connected direction is identical, it is ensured that connector body plug under train high-speed cruising environment still
Can ensure that stable contact, when adapter needs the withdraw of the needle, simple to operate, contact pin jump ring will not be caused damage, improve greatly
The anticreep performance of contact pin.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；
Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that:
Technical scheme described in foregoing embodiments still can be modified by it, or carries out wherein portion of techniques feature
