Description
Technical field
The present invention relates to the connected mode of technical field of electric connectors contact and contact seat, especially a kind of demountable structure of contact.
Background technology
Contact is the core part in connector, and he is for the Signal transmissions of connector, under the use occasion of a lot of connector, connector is needed to have maintenanceability, can be convenient to when contact generation problem change, or be convenient to client oneself assembling, this just needs contact to have detachability.In industry, Demountable contact element generally adopts jack catchs type to fix, and on contact, namely arranges outer support thorn claw or in pedestal, arrange inner support thorn claw, to be fixed in pedestal by contact.The claw of prior art is the elastic component of three, annular band support Ci Tezheng, and the punching of general use elastic metallic material forms.Problems existing is, this structure has significant limitation, is mainly the requirement of strength of claw material very high, and require high to the fit dimension of contact and pedestal, whole connector processing cost is high.And its contact is mainly fixing by support thorn in pedestal, is easily stressedly subjected to displacement, ruptures, affect connector connection reliability and through-current capability.
Summary of the invention
The demountable structure of a kind of contact provided for the deficiencies in the prior art is provided, the present invention has that structure is simple, assembling and convenient disassembly, low cost of manufacture and functional reliability is high, be applicable to the advantage of high current connector.
The concrete technical scheme realizing the object of the invention is:
A kind of demountable structure of contact, its feature comprises contact seat, contact and snap ring, described contact seat is provided with through hole, through hole is divided into the first contact holes and the second contact holes vertically, boss is provided with between first contact holes and the second contact holes, contact is cylindrical member, it is provided with vertically the first external diameter and the second external diameter, the first groove and the second groove is provided with between first external diameter and the second external diameter, snap ring is the tubular annulus that one end is provided with tapering, and its annulus axially has groove; Described contact is located in the through hole of contact seat, and in the first external diameter on contact and the second external diameter the first contact holes of laying respectively at contact seat and the second contact holes, on contact, the first groove is positioned at the boss of contact seat, and snap ring is located between the second groove of contact and the second contact holes of contact seat.
The present invention has that structure is simple, assembling and convenient disassembly, low cost of manufacture and functional reliability is high, the advantage of big current.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of contact seat of the present invention;
Fig. 3 is the structural representation of contact of the present invention;
Fig. 4 is the structural representation of snap ring of the present invention.
Embodiment
Consult Fig. 1 ~ Fig. 4, the present invention includes contact seat 11, contact 12 and snap ring 13, described contact seat 11 is provided with through hole, through hole is divided into the first contact holes 111 and the second contact holes 112 vertically, boss 113 is provided with between first contact holes 111 and the second contact holes 112, contact 12 is cylindrical member, it is provided with vertically the first external diameter 121 and the second external diameter 122, the first groove 123 and the second groove 124 is provided with between first external diameter 121 and the second external diameter 122, snap ring 13 is provided with the tubular annulus of tapering for one end, and its annulus axially has groove 131; Described contact 12 is located in the through hole of contact seat 11, and in the first external diameter 121 on contact 12 and the second external diameter 122 the first contact holes 111 of laying respectively at contact seat 11 and the second contact holes 112, on contact 12, the first groove 123 is positioned at the boss 113 of contact seat 11, snap ring 13 is located between the second groove 124 of contact 12 and the second contact holes 112 of contact seat 11.
The present invention uses like this:
Consult Fig. 1 ~ Fig. 4, the present invention includes pedestal 11, contact 12 and snap ring 13, described contact 12 is located in the through hole of contact seat 11, and in the first external diameter 121 on contact 12 and second diameter bore 122 the first contact holes 111 of laying respectively at contact seat 11 and the second contact holes 112, with the first contact holes 111 of the first external diameter 121 on contact 12 and contact seat 11 for coordinating benchmark, and select matched in clearance; The second external diameter 122 on contact 12 is matched in clearance with the second contact holes 112 of contact seat 11;
On contact 12, the first groove 123 is positioned at the boss 113 of contact seat 11, and boss 113 defines the top-down monodisplacement of contact 12;
What snap ring 13 was made for elastomeric material is axially arranged with the elastic ring having groove 131, snap ring 13 is located between the second groove 124 of contact 12 and the second contact holes 112 of contact seat 11, because snap ring 13 is defined in the second groove 124 of contact 12, when contact 12 is penetrated to the second contact holes 112 by the first contact holes 111 of contact seat 11 together with snap ring 13, snap ring 13 is by compression, continue to penetrate with contact 12, snap ring 13 is by entering the second contact holes 112 after the boss 113 of contact seat 11, snap ring 13 is released, recover original shape, now, snap ring 13 defines contact 12 monodisplacement from bottom to top in contact seat 11, realize contact 12 effectively fixing in contact seat 11,
During dismounting, second contact holes 112 of socket wrench specially adapted for it by contact seat 11 is inserted, the tapering end of snap ring 13 is touched in sleeve termination, with sleeve axial force distribution, by compression under the effect of snap ring 13 tapering, now, contact 12 can be ejected to the first contact holes 111 together with second contact holes 112 of snap ring 13 by contact seat 11, complete dismounting.
The present invention is all realized by compression by snap ring 13 in assembling or unloading process, can not scratch contact seat 11, realizes conveniently installation and removal.
The present invention, compared with the claw structure of prior art, has connection reliability high, stronger to the holding capabilities of contact, can meet the fixing of large contact, thus be applicable to high current connector, is convenient to machining and production cost is low.
