Description of the drawings
Fig. 1 is a kind of schematic cross-sectional view of telescopic unilateral limit connector of the utility model.
Fig. 2 is a kind of configuration schematic diagram of telescopic unilateral limit connector of the utility model.
Specific implementation mode
The utility model provides a kind of telescopic unilateral 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 unilateral limit connector, as depicted in figs. 1 and 2, including tubular contact shrapnel 1, fastening ring 2 and set
Cylinder 3,3 one end of sleeve are equipped with the position limiting convex ring 4 for limiting 1 displacement of tubular contact shrapnel, and the other end is equipped with to be fixed for assembling
The annular of ring 2 matches access slot 5.
One end limit is realized by position limiting convex ring 4, and other end limit is realized with access slot 5 with annular by fastening ring 2, is realized
Both ends limit to tubular contact shrapnel 1.
The tapered structure in periphery of the fastening ring 2, 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 position limiting convex ring 4 and fastening ring 2
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, tubular contact shrapnel 1 is loaded into sleeve 3 first so that one end of tubular contact shrapnel 1 and position limiting convex ring 4
It abuts against, then crimps the narrow end of fastening ring 2 into sleeve 3 towards tubular contact shrapnel 1, by squeezing fastening ring 2 so that card
Match in access slot 5 Gu ring 2 is fastened on annular, after mating, the whole embedded annular mating slot 5 of fastening ring 2, by 1 axis of tubular contact shrapnel
To fixing.
It should be noted that mode of traditional fastening ring using riveting, interference mating, electric welding or molten tin, these
Traditional docked mode has 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.The diagram of the metal washer is omitted in attached drawing.
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 unilateral 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.
