Initial position, positioning through hole can be corresponded to by the positioning through hole 9 of positioning pin 11, interior insulation body 3 by being offered on 2 side of shell
9 settings fluted 10, the length direction of groove 10 is parallel with the telescopic direction of interior insulation body 3, and positioning pin 11 passes through positioning through hole 9
And stretch in groove 10, to limit axial rotation of the interior insulation body 3 before hitch is even hung.Wherein, in order to enable present invention knot
Structure is more stablized, and the quantity of positioning through hole 9, positioning pin 11 and groove 10 could be provided as multiple.
For the structure of above-mentioned groove 10, specially：As shown in figure 3, groove 10 can be rectangular channel, positioning pin 11 stretches into
One end side wall of groove 10 and the two side walls of groove 10 in the direction of the width are tangent.In addition, as shown in Figure 4 and Figure 5, groove 10
It may be arranged as：Groove 10 includes first concave part 12 and width of the size more than 11 diameter of positioning pin of width direction
The size in direction is equal to the second concave part 13 of 11 diameter of positioning pin, and before hitch is even hung, positioning pin 11 stretches into one end of groove 10
In the first concave part 12；After hitch is even hung, one end that positioning pin 11 stretches into groove 10 is located in the second concave part 13.
It should be noted that the present invention by shell 2 set positioning pin 11, interior insulator 3 set groove 10 and
Recessed poor 10 are set to include the first concave part 12 and the second concave part 13 so that floating type multicore electrical cnnector is in train operation
When, the offset in axial rotation direction between compensation docking hitch can be played, further reduces the abrasion of moving contact 1 with this, and
It can make the rotation return automatically of interior insulation body 3 in coupler-uncoupling.
Preferably, as shown in Fig. 4 or Fig. 5, in order to make 11 returning quickly of positioning pin in coupler-uncoupling to the first concave part
In 12, and reduce the impact occurred with 4 side arm of groove, can set smoothed between the first concave part 12 and the second concave part 13
It crosses.For the structure of above-mentioned first concave part, 12 and second concave part 13, specially：, as shown in figure 4,12 He of the first concave part
Second concave part 13 forms the structure of similar sector；As shown in figure 5, the first concave part 12 is rectangular channel, the second concave part 13
Two sides are cambered surface, and tangent with the junction of the first concave part 12 and the two sides of the first concave part 12.
It should be noted that by the way that the second contact surface 4 and third contact surface 15 are set as the conical surface, it is fixed in the setting of shell 2
Position pin 11, interior insulator 3 set groove 10 and setting recessed poor 10 include the first concave part 12 and the second concave part 13, one
For aspect in train operation, interior insulation body 3 can compensate for gap of the docking hitch on X, Y, Z and axial-rotation direction, into one
Step reduces the abrasion of moving contact 1, ensures the stability of signal transmission；On the other hand, interior insulation body 3 can be made in coupler-uncoupling
Self-return, the hitch that need not be manually adjusted with this can be such that the present invention is directly used in next time are even hung.
Preferably, as depicted in figs. 1 and 2, in order to ensure leakproofness higher between interior insulation body 3 and shell 2, inside absolutely
One end that edge body 3 installs contact 1 can be arranged dust cover 14, and be provided with to install between dust cover 14 and interior insulation body 3
The end ring 5 of dust cover.
As shown in Figure 1, Figure 2, shown in Fig. 4 and Fig. 5, use process of the invention is as follows；
When hitch is even hung, the hitch of two docking hitches even hangs 8 relative motion of end face, promotes the first of two interior insulation bodies 3
4 centering of contact surface, which contacts, simultaneously mutually to be squeezed, so that interior insulation body 3 overcomes the resistance of elastic element 6 along shell axial shrinkage,
End face 8 is even hung until the hitch of two docking hitches to be bonded completely.
During train operation, two hitches for docking hitches can generate gap between even hanging end face 8, and interior insulation body 3 passes through elastic member
Under the action of part 6 in shell 2 stretch, and compensate two docking hitches hitches even hang end face 8 between along current of traffic
Gap.Offset of the interior insulation body 3 by positioning pin 11 in the second concave part 13 (as shown in Fig. 4 or Fig. 5), two pairs of compensation pick up
The gap on direction is axially rotated between the hitch company extension end face 8 of hook.
During coupler-uncoupling, interior insulation body 3 stretches out return under the action of elastic element 6.In the process, interior insulation body 3 with it is outer
Pass through conical surface contact between shell 2 so that interior insulation body 3 realizes accurate return in the X, Y, Z direction.The lower end of positioning pin 11 from
Second concave part 13 moves to the first concave part 12 so that interior insulation body 3 realizes the accurate return in rotation direction.
