Detailed description of the invention
With embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
As shown in figures 1-8, a kind of helmet goes between with pulling electric connector, including: plug 1 and socket 2；
Plug 1 includes plug casing 11, coupling nut 12, contact pin 13, interface sealing body 14, pin
Insulator 17, jump ring I 18, locking nut 19, tail nut after front insulator 15, spring 16, pin
Ⅰ110；Arrange and be located at plug casing 11 before and after insulator 17 after insulator 15 and pin before pin internal,
Before pin after insulator 15 and pin insulator 17 by positioning table I 11a of plug casing 11 and jump ring I
18 axially position, and it is internal, before pin that insulator 17 after insulator 15 and pin is located at before pin by contact pin 13
Insulator 15 front end is provided with interface sealing body 14, and it is outside that coupling nut 12 is sheathed on plug casing 11,
Locking nut 19 is connected with coupling nut 12 rear threads, and spring 16 is located at plug casing 11 and is connected
Connect between nut 12 and be compressed making positioning table II 11b of plug casing 11 by locking nut 19
Fit with positioning table III 12a of coupling nut 12, tail nut I 110 and plug casing 11 rear threads
Connect；
Socket 2 includes insulator 24, hole before ball 21, Socket casing 22, plugging hole component 23, hole
Rear insulator 25, jump ring II 26, tail nut II 27；Before hole behind insulator 24 and hole before insulator 25
It is internal that Socket casing 22 is also located in rear setting, and before hole, behind insulator 24 and hole, insulator 25 passes through socket
Positioning table IV 22a and the jump ring II 26 of housing 22 axially position, before plugging hole component 23 is located at hole
After insulator 24 and hole, insulator 25 is internal, and tail nut II 27 is connected with Socket casing 22 rear threads；
The anterior riveting of Socket casing 22 has 3 balls being along the circumferential direction uniformly arranged 21, coupling nut
12 front inner wall are provided with the ball annular groove 12b coordinated with ball 21, the anterior outer wall of plug casing 11
Being provided with 3 ball guiding groove 11d coordinated with ball 21, plug casing 11 front portion is provided with boss 11c；
Plug 1, socket 2 are internal uses two traditional body insulator structures, tail nut I 110 and tail spiral shell
Being equipped with through hole on cap II 27, be fixed with pin in through hole, when making cable, on pin, colligation is strengthened
Rope, is used for bearing and pulls pull out force.
This utility model slips into ball annular groove 12b by ball 21 and realizes connection and put in place, and ball 21 takes off
Realize pulling separation from ball annular groove 12b；Axial phase between coupling nut 12 with plug casing 11
To displacement, being to control whether ball 21 can slip into the key in ball annular groove 12b, this is axially opposing
Displacement overcomes spring force to realize by coupling nut 12 and plug casing 11.Connect in detail, divide
As follows from process:
1. such as Fig. 5, when docking starts, coupling nut 12 and Socket casing 22 are promoted in opposite directions with right-hand man,
Ball 21 is made to form extruding with the boss 11c of plug casing 11.The now positioning table of coupling nut 12
III 12a fits with positioning table II 11b of plug casing 11, and ball 21 cannot slip into coupling nut 12
Ball annular groove 12b in.
2., such as Fig. 6, when insertion force reaches certain value, the extruding force of ball 21 and plug casing 11 is made
Becoming spring 16 to compress further, now between coupling nut 12 and plug casing 11, stroke L is sufficiently large,
Ball 21 just can slip in the ball annular groove 12b of coupling nut 12.
3. such as Fig. 7, when ball 21 is slid completely into the ball annular groove 12b of coupling nut 12, Fig. 5,
At axial compression in Fig. 6,3 disappear, therefore under spring 16 elastic force effect, determining of coupling nut 12
Position platform III 12a fits again with positioning table II 11b of plug casing 11, now enters docking hold mode.
The most reversely pulling coupling nut 12 and Socket casing 22, positioning table III 12a of coupling nut 12 is with slotting
To tend between positioning table II 11b of casing 11 keep laminating, so method cannot make plug 1,
Socket 2 separates.
4., such as Fig. 8, when in emergency circumstances pilot seat launches, cable is strengthened rope and is drawn by pin
Dragging the tail nut II 27 of the tail nut I 110 of plug 1, socket 2, pulling-out force causes spring 16 to enter one
Step compression, row when between positioning table III 12a of coupling nut 12 and positioning table II 11b of plug casing 11
When journey L is sufficiently large, ball 21 can skid off ball annular groove 12b, and product returns to the state shown in Fig. 5,
Continuing to exert a force, plug 1, socket 2 realize pulling separation.
Under nonemergency, it is possible to pulled tail nut I 110 and the tail nut II 27 at two ends by right-hand man
Plug 1, socket 2 is made to realize pulling separation.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow ripe
The personage knowing technique will appreciate that content of the present utility model and implements according to this, can not limit with this
Make protection domain of the present utility model.All according to this utility model spirit made equivalence change or
Modify, all should contain within protection domain of the present utility model.
