Background technology
Contact is the core part in connector, and he is used for the signal transmission of connector, in the use of many connectors
, it is necessary to connector has maintenanceability under occasion, can be conveniently replaceable when contact occurs problem, or be easy to client oneself
Assembling, this is accomplished by contact has detachability.Demountable contact element is typically fixed using jack catchs type in industry, i.e., in contact
Outer support thorn claw is set on part or inner support thorn claw is set in pedestal, so that contact is fixed in pedestal.Prior art
Claw be an annular with three elastic components of support thorn feature, generally use elastic metallic material punching and form.Exist
Problem is that this structure has significant limitation, essentially consist in it is very high to the intensity requirement of claw material, to contact and pedestal
Fit dimension requirement it is high, whole connector high processing costs.And its contact is mainly fixed in pedestal by support thorn, is easily received
Power is subjected to displacement, is broken, and influences connector connection reliability and through-current capability.
The content of the invention
A kind of demountable structure of contact that the purpose of the present invention is directed to the deficiencies in the prior art and provides, the present invention
With simple structure, assembling and convenient disassembly, low cost of manufacture and functional reliability is high, it is adaptable to high current connector it is excellent
Point.
Realizing the concrete technical scheme of the object of the invention is：
A kind of demountable structure of contact, its feature includes contact seat, contact and snap ring, on the contact seat
Through hole is provided with, through hole is divided into the first contact holes and the second contact holes, the first contact holes and the second contact holes vertically
Between be provided with boss, contact is cylindrical member, first external diameter and second external diameter is provided with vertically thereon, outside first external diameter and second
The first groove and the second groove are provided between footpath, snap ring is provided with the tubular annulus of taper for one end, and its annulus is axially provided with groove；
The contact is in the through hole of contact seat, and first external diameter and second external diameter on contact are located at contact seat respectively
The first contact holes and the second contact holes in, on contact the first groove be located at contact seat boss in, snap ring is located at
Between second contact holes of the second groove and the contact seat of contact.
The present invention has simple structure, assembling and convenient disassembly, a low cost of manufacture and functional reliability is high, high current it is excellent
Point.
Brief description of the drawings
Fig. 1 is structural representation of the 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.
Specific embodiment
Refering to Fig. 1~Fig. 4, the present invention includes contact seat 11, contact 12 and snap ring 13, is set on the contact seat 11
There is through hole, through hole is divided into the first contact holes 111 and the second contact holes 112 vertically, and the first contact holes 111 and second connect
Boss 113 is provided between contact element hole 112, contact 12 is cylindrical member, is provided with first external diameter 121 and second external diameter vertically thereon
122, the first groove 123 and the second groove 124 are provided between first external diameter 121 and second external diameter 122, snap ring 13 is provided with for one end
The tubular annulus of taper, its annulus is axially provided with groove 131；The contact 12 connects in the through hole of contact seat 11
First external diameter 121 and second external diameter 122 in contact element 12 connect positioned at the first contact holes 111 of contact seat 11 and second respectively
First groove 123 is located in the boss 113 of contact seat 11 in contact element hole 112, on contact 12, and snap ring 13 is located at contact 12
The second groove 124 and contact seat 11 the second contact holes 112 between.
The present invention is so to use：
Refering to Fig. 1~Fig. 4, the present invention includes pedestal 11, contact 12 and snap ring 13, and the contact 12 is located at contact
In the through hole of seat 11, and first external diameter 121 and second diameter bore 122 on contact 12 are located at the first of contact seat 11 respectively
In the contact holes 112 of contact holes 111 and second, connect with the first of contact seat 11 with the first external diameter 121 on contact 12
Contact element hole 111 is coordinated to coordinate benchmark from gap；Second external diameter 122 and the second of contact seat 11 on contact 12
Contact holes 112 coordinates for gap；
First groove 123 is located in the boss 113 of contact seat 11 on contact 12, and boss 113 defines contact 12
Top-down monodisplacement；
Snap ring 13 is axially arranged with the elastic ring for being provided with groove 131 for what elastomeric material was made, and snap ring 13 is located at contact 12
The second groove 124 and contact seat 11 the second contact holes 112 between, because snap ring 13 is defined to contact 12
In second groove 124, when contact 12 together with snap ring 13 from contact seat 11 the first contact holes 111 to the second contact holes
112 when penetrating, and snap ring 13 continues to penetrate by compression with contact 12, after boss 113 of the snap ring 13 by contact seat 11
Into the second contact holes 112, snap ring 13 is released, and recovers original shape, and now, snap ring 13 defines contact 12 in contact
Monodisplacement in part seat 11 from bottom to top, realizes effective fixation of the contact 12 in contact seat 11；
During dismounting, socket wrench specially adapted for it is inserted by the second contact holes 112 of contact seat 11, snap ring 13 is touched in sleeve termination
Taper end, with sleeve axial force distribution, by compression in the presence of the taper of snap ring 13, now, you can connect contact 12
Ejected to the first contact holes 111 from the second contact holes 112 of contact seat 11 with snap ring 13, complete dismounting.
It is of the invention to be realized by compression by snap ring 13 during assembly and disassembly, will not scratch contact seat
11, realize conveniently installing and dismounting.
The present invention compared with the claw structure of prior art, with connection reliability it is high, to the holding capabilities of contact more
By force, the fixation of big contact can be met, so as to be applied to high current connector, is easy to machining and low production cost.
