Detailed description of the invention
Below in conjunction with embodiment accompanying drawing, lightness round electric connector tail accessory of the present invention is done further
Describe in detail:
If Fig. 3 is to embodiment illustrated in fig. 7, lightness round electric connector tail accessory of the present invention, it is by swivel nut 1, tail
Portion's shell 2 and grommet 3 form.Swivel nut 1 butt end is provided with female thread 11, for being connected with connector body part 4, the most logical
Cross and screw swivel nut 1 and make the butt end female thread 11 of swivel nut 1 capture connector body part 4 tail end external screw thread (not shown), and then
Whole tail accessory is driven to be connected with connector body part 4 afterbody；Swivel nut 1 inner chamber is provided with cannelure 12, is used for loading afterbody
The connection end 21 of shell 2 also realizes axial limiting by cannelure 12 front-rear side walls 13, prevents afterbody shell 2 from deviating from vertically；
Swivel nut 1 uses circular profile and at surface configuration anti-slip tank 14, can conveniently screw；Swivel nut 1 tail end is provided with uniform 3 of circumference to be prevented
The safe string holes 15 of pine, may pass through the locking safety line 5 for colligation afterbody shell 2.The connection end 21 of afterbody shell 2 passes through interference
In fit system press-in swivel nut 1, it is notching construction that afterbody shell 2 connects end 21, i.e. multiple circumferentially having of connection end 21
Axially grooved 29, therefore connect end 21 and can produce, when interference loads swivel nut 1, the elastic deformation radially closed up, make afterbody shell
2 connect in the cannelure 12 that end 21 external diameter diminishes to load swivel nut 1.After connection end 21 loading of afterbody shell 2 puts in place, outside afterbody
Shell 2 connects the resilient-elasticity recovery of end 21, external diameter increases, and snaps in the cannelure 12 of swivel nut 1 inner chamber, now afterbody shell 2
Connect end 21 and coordinate realization axially location with cannelure 12 front-rear side walls 13 of swivel nut 1 inner chamber by its former and later two step surfaces；
For realizing the anti-rotation after tail accessory assembles with connector body part, in the connection end 21 of afterbody shell 2, first stop is set
Tooth 22, can engage with the second stop tooth (not shown) of connector body part tail end；Afterbody shell 2 inner chamber is designed with annular table
Rank 23, for axial restraint grommet 3；Afterbody shell 2 afterbody arranges bracket 24, for the colligation of tail cable wire harness 6, it is provided that
The support of core of a cable；Bracket 24 includes that afterbody shell 2 one side that bracket main body 28, bracket main body 28 are tubulose extends back
The support come, bracket main body 28, closer to tail end gradually inward deflection, contrasts this compact conformation of prior art, takes up room relatively
Little.Tail end at afterbody shell 2 bracket main body 28 is provided with radially outer fan-shaped boss 25, for the axial limit of binding strap 7
Position, prevents binding strap 7 from retreating abjection；Afterbody shell 2 is additionally provided with the muscle shape boss 26 extended radially outward at muscle shape boss
Being provided with arched part 27 on 26, arched part 27 is provided with circular hole 271, may pass through the locking safety for colligation afterbody shell 2
Line 5.Bracket main body 28 is played the effect strengthening supporting by muscle shape boss 26.Meanwhile, between fan-shaped boss 25 and muscle shape boss 26
Constitute a stopper slot, for limiting the position of binding strap 7.Grommet 3 is elastic rubbery body, and inside is provided with cellular circular hole
31, when adapter uses, the wire 8 of tail end passes from cellular circular hole 31, wire 8 and the cellular circular hole 31 in grommet 3
For interference fit, grommet produces compression, by the tight of grommet 3 with wire 8, can prevent environmental liquids, ash
Dirt etc. enter inside adapter from tail accessory tail end, thus play the sealed damp-proof effect of adapter tail end.
