Also circumferentially for uniform intervals arrangement there are three convex key 211, three convex keys 211 are used to be caught in the groove 38 on rotation stop set 32 for front end
In, realize that Socket casing 21 and the circumferential rotation stop of rotation stop set 32 assemble.It, can be by groove arrangement in socket shell in other embodiments
The front end of body, and convex key is arranged in rotation stop and is put on.
After 200 grafting in place of plug 100 and socket, need to carry out locking by coupling nut component 300.Coupling nut
For the structure of component 300 as shown in Fig. 2, Fig. 3, Fig. 7 and Fig. 8, coupling nut component 300 includes the company being sleeved on plug casing 11
Connect nut 31.Define coupling nut 31 in towards one end of socket 200 be front end, towards one end of plug 100 be rear end.Connection
The front end of nut 31 is distributed along the circumference at three track groove 35 at bail hole and three, and when assembling, bail 39 is passed through the side of riveting
Formula is fixed in bail hole, and the radial inner end of bail 39 extends in coupling nut 31.Coupling nut 31 is axial step structure, preceding
Hold inside and outside diameter larger, rear end is hexagonal structure, can by tool rotate coupling nut 31, make bail 39 on socket 200 three
Locate 210 screw of spiral channel, and then realizes plugging together and separating between plug 100 and socket 200.In coupling nut 31
Rear end offers external screw thread, for 34 Screw assembly of threaded collar.
As shown in Figure 13 and Figure 15, the generally T shape of track groove 35, track groove 35 includes that locked groove is solved at the two of circumferentially extending
311, solution locked groove 311 is connected at two, and the intersection that locked groove 311 is solved at two is provided with lock groove 310, and lock groove 310 is along preceding
Rear direction extends, and lock groove 310 is connected with solution locked groove 311, and the outer circumferential for throughout solving locked groove 311 is additionally provided with rotation stop groove
312, rotation stop groove 312 is connected with solution locked groove 311.Track groove 35 can be embedded in for ball 37.
Coupling nut component 300 further includes rotation stop set 32, and rotation stop set 32 is sleeved on the outside of coupling nut 31, rotation stop set 32
It can be moved forward and backward relative to coupling nut 31.Track groove 35 offers at the front end of rotation stop set 32 is corresponding to three leads at three
Hole, at three through-hole be used to it is corresponding place ball 37, as shown in fig. 7, being placed with ball 37 in through-hole, and pass through 36 envelope of rivet
Dress prevents ball 37 from deviating from, and 37 a part of ball is located in track groove 35, and another part is located in the through-hole of rotation stop set 32, leads to
Crossing ball 37 may be implemented the rotation stop cooperation of rotation stop set 32 and coupling nut 31.In the present embodiment, ball 37 constitutes radial convex
Portion, i.e. nut rotation stop connected structure and unlock connected structure.The presence of ball 37 can guarantee rotation stop set 32 and coupling nut 31
When relatively movable, friction between the two is rolling friction, mitigates abrasion.Ball 37 can be with the inner wall block of track groove 35
Cooperate, in other embodiments, nut rotation stop connected structure and unlock connected structure can be the structures such as pin, bail, convex key.
As shown in fig. 7, the rear end of rotation stop set 32 has a turn edge backwards, when assembly, arranged at the rear of the turn edge
There is pressure spring 33, and the threaded collar 34 by being screwed on coupling nut 31 realizes anticreep.In the front inner wall of rotation stop set 32
Groove 38 at three are distributed along the circumference with, groove 38 is for mating in the axial direction with the convex key 211 in socket 200, to realize
Rotation stop between Socket casing 21 and rotation stop set 32 is assembled.In the present embodiment, groove 38 constitutes shell rotation stop connected structure.And
Rotation stop set 32 constitutes the rotation stop set being set in outside coupling nut 31, i.e. rotation stop set.
It is of the invention use process is as follows: when plug 100 and socket 200 plug together, Socket casing 21 extends to coupling nut 31
In, the screw in the spiral channel 210 on socket 200 of bail 39 in coupling nut 31, the Socket casing 21 of socket 200
It presses against on plug casing 11, plug casing 11 and coupling nut 31 move towards simultaneously compresses bellows spring 114, when bail 39 moves
When moving to the end of spiral channel 210, bail 39 and coupling nut 31 are under the elastic reaction of ripple spring 114 along front and back
It is held out against on the cell wall of spiral channel 210 to (i.e. axial), has reached axial restraint.As is illustrated by figs. 11 and 12, when bail 39
When being moved to the end of spiral channel 210, ball 37 is placed in lock groove 310, realize coupling nut 31 and rotation stop set 32 it
Between the assembly of circumferential rotation stop, and rotation stop set 32 holds out against ball 37 before lock groove 310 under the elastic acting force of pressure spring 33
Side end.At this point, three convex keys 211 correspondence being arranged on Socket casing 21 is axially inserted into groove 38, socket shell is realized
Rotation stop between body 21 and rotation stop set 32 is assembled, moreover, because having been realized in circumferential direction between rotation stop set 32 and coupling nut 31
Rotation stop, so that Socket casing 21 and 32 entirety of rotation stop set realize circumferential rotation stop.Coupling nut 31 will not rotate, bail 39
The position of plug 100 and socket 200 will not be subjected to locking by circumferentially rotating abjection in spiral channel 210.As long as at this point, not
External force in the front-back direction is applied to rotation stop set 32, rotation stop set 32 will not circumferentially rotate, and plug 100 and socket 200 are maintained at
The position plugged together is constant.At this point, the location of rotation stop set 32 is locking position.Rotation stop set 32 is moved forward by the driving of pressure spring 33
Stroke is front travel, and locking position is the extreme position of front travel.
As shown in Figure 14 and Figure 15, when unlock, rotation stop set 32 is pulled back, rotation stop set 32 drives ball 37 along lock groove
310 are moved rearwardly at the position to connect with solution locked groove 311, and ball 37 and lock groove 310 are detached from circumferential block, 211 He of convex key
Groove 38 is also detached from circumferential block, at this point, rotation rotation stop set 32, moves ball 37 along one of solution locked groove 311, and final
Ball 37 is pushed into rotation stop groove 312 under the elastic acting force of pressure spring 33, is maintained at ball 37 in rotation stop groove 312.Convex key
211 and groove 38 be detached from circumferential block and can be rotatablely connected nut 31 after ball 37 and lock groove 310 are detached from circumferential block, gram
The elastic acting force for taking ripple spring 114 produces the bail 39 on coupling nut 31 by spiral in spiral channel 210, plug
100 and socket 200 realize unlock.When ball 37, which is moved to lock groove 310, conciliates 311 joint of locked groove, locating for rotation stop set 32
Position be Xie Suowei, the extreme position that pivoted housing 32 moves backward until position this moment.
In the present embodiment, plug casing 11 and Socket casing 21 are connector shell, and Plug contact 15 and socket connect
Contact element 25 is needle contact piece.
In the present embodiment, the mineral insulation cable being connected on plug 100 constitutes plug insulation cable, is connected to socket
Mineral insulation cable on 200 constitutes socket insulation cable.
