Description of the drawings
Fig. 1 is a kind of schematic cross-sectional view of telescopic bilateral limit connector of the utility model.
Fig. 2 is a kind of configuration schematic diagram of telescopic bilateral limit connector of the utility model.
Specific implementation mode
The utility model provides a kind of telescopic bilateral limit connector.Below in conjunction with attached drawing to the utility model technical side
Case is described in detail, so that it is more readily understood and grasps.
A kind of telescopic bilateral limit connector, as depicted in figs. 1 and 2, including tubular contact shrapnel 1 and sleeve 3, sleeve
3 both ends are respectively equipped with annular and match access slot 5, and for any annular with fastening ring 2 is equipped in access slot 5, the periphery of fastening ring 2 is tapered
Structure, annular match with access slot 5 with fastening ring 2.
Tubular contact shrapnel 1 is set in sleeve 3, and fastening ring 2 is tight at annular in access slot 5, and tubular contact shrapnel 1 limits
Between the fastening ring 2 at both ends.
It is described in detail, one end outer circumference diameter of the fastening ring 2 towards tubular contact shrapnel 1 is less than to be connect away from tubulose
One end outer circumference diameter of shrapnel 1, the tapered structure in periphery are touched, and the annular matches the shape and the pyramidal structure phase of access slot 5
Match, so-called matching is simultaneously not all consistent, and at least axial wide end of the annular with access slot 5 is consistent with the thickness of fastening ring 5.
When being assembled, one end assembly is carried out first, i.e., by carrying out the mating of fastening ring 2, card in one end of casing 3
Gu ring 2 is fastened on annular in access slot 5, then tubular contact shrapnel 1 is loaded into sleeve 3 so that the one of tubular contact shrapnel 1
End is abutted against with the fastening ring 2 fastened, then crimps the narrow end of the fastening ring of the other end 2 towards tubular contact shrapnel 1
Enter sleeve 3, by squeezing fastening ring 2 so that fastening ring 2 is fastened on annular in access slot 5, after mating, fastening ring 2 is whole embedded
Annular matches access slot 5, by the axial fixing of tubular contact shrapnel 1.
It should be noted that mode of traditional fastening ring 2 using riveting, interference mating, electric welding or molten tin, this
A little traditional docked modes have that firmness is poor.
In order to increase structural strength, fastening ring 2 is metal fastening ring.In addition, when there is fit-up gap, by fixing
Metal washer is set between ring 2 and tubular contact shrapnel 1 and can adjust fit-up gap so that the axial direction of tubular contact shrapnel 1 is stablized,
It will not deviate.When there is gap, it is only necessary to use a metal washer, the figure of the metal washer is omitted in attached drawing
Show.
Tubular contact shrapnel 1 in this case is sleeve-shaped grid shrapnel.The sleeve-shaped grid shrapnel has certain axial direction
Elastic shrinkage amount can suitably reduce axial mounting distance in design, such as design mounting distance is 3cm, according to each part
Plus-minus tolerance, carry out mounting distance reduction, the distance of the reduction by tubular contact shrapnel 1, adjusted by the amount of elasticity of itself
It is whole, it is low to the required precision of each parts of product.
Finally, the both ends of tubular contact shrapnel 1 are equipped with snap ring 6, and snap ring 6 and the inner cavity phase interference of sleeve are coupled.The interference
Secondary fixed mode is played in mating, i.e., fastening ring 2 is used as first axis fixed structure, and the snap ring 6 is as to tubular contact
Second axial fixing structure of shrapnel 1, the two can ensure that the assembly fastness of tubular contact shrapnel 1.
By foregoing description, a kind of telescopic bilateral limit connector of the utility model, using the fastening ring of pyramidal structure,
Coordinated with access slot with annular, axial locking can be carried out to tubular contact shrapnel, stability is better than traditional couplings.
Sleeve-shaped grid shrapnel has certain axial elasticity amount, can reduce the requirement to part axial precision.Tubular contact shrapnel is certainly
Band axial limit structure, assembling structure intensity are high.Terminal with compact integral structure, stability are reliable, service life is long, easy to spread answer
With.
The technical solution of the utility model is fully described above, it should be noted that the tool of the utility model
Body embodiment is simultaneously not limited by the description set out above, and those skilled in the art exist according to the Spirit Essence of the utility model
All technical solutions that structure, method or function etc. are formed using equivalents or equivalent transformation, all fall within this reality
Within novel protection domain.
