Description
Technical field
The present invention relates to connector technique field, especially a kind of resilient contact of Spring capable of diameter varying.
Background technology
The resilient contact that prior art in the market is used for connector mainly has leaf spring formula jack, hat spring formula jack, coil spring
Formula jack or spring in spring jack.The problem of existing be, when to plug together feature be that plug is initially inserted into of these jacks, insertion force compared with
Greatly, conversely, withdrawal force is also larger once plugged together, the frictional force of the jack of above-mentioned resilient contact produced by during plugging together
It is directly proportional with the normal pressure positive correlation of plug, the i.e. contact engaging and separating force of plug to the frictional force of jack.The mistake plugged repeatedly in connector
Cheng Zhong, causes jack to replace stress, to reach fatigue limit, reduces the reliability of connector product, service life shortens.
The content of the invention
A kind of resilient contact for Spring capable of diameter varying that the purpose of the present invention is in view of the shortcomings of the prior art and provided, this hair
Bright use sets Spring capable of diameter varying in jack matrix, and when plug and Spring capable of diameter varying grafting, the normal pressure in each portion of its plug is divided
Solution is on the turn of Spring capable of diameter varying different-diameter, and Spring capable of diameter varying will not extend and shrink simultaneously, so that it is overall to change jack
Alternately the present situation of stress, is not likely to produce fatigue, makes that the reliability of connector product is improved, service life is greatly prolonged.
Realizing the concrete technical scheme of the object of the invention is：
A kind of resilient contact of Spring capable of diameter varying, its feature includes jack matrix, Spring capable of diameter varying, overcoat and plug, the jack
Matrix be one end be provided with spring eye cylindrical member, the Spring capable of diameter varying be variable cross-section ring spring, its variable cross-section ring spring along axis successively
Provided with the first grade circle external diameter, roundlet external diameter, variable cross-section external diameter, the circle external diameter such as second and great circle external diameter, the overcoat sets for nozzle
Have a tubular elements of closing in, the plug is the cylindrical member that one end is provided with contact head, its contact head along axis be sequentially provided with small column,
Bore cylinder and wait cylinder；
The Spring capable of diameter varying is in the spring eye of jack matrix, and coat suit is on the outside of jack matrix, and Spring capable of diameter varying is big
Circle external diameter is connected between the end face of jack matrix and the closing in of overcoat；The contact head of plug is plugged on Spring capable of diameter varying through overcoat
It is interior, and the small column of plug, bore cylinder and wait cylinder respectively with the roundlet external diameter of Spring capable of diameter varying, variable cross-section external diameter and the circle such as second
External diameter is touched；The internal diameter of described overcoat is tight fit with the external diameter of jack matrix；The termination of small column is on described plug
Bulb.
The present invention in jack matrix using Spring capable of diameter varying is set, when plug and Spring capable of diameter varying grafting, each portion of its plug
Normal pressure be broken down on the turn of Spring capable of diameter varying different-diameter, Spring capable of diameter varying will not extend and shrink simultaneously, so as to change
Become jack integrally replace stress present situation, be not likely to produce fatigue, improve the reliability of connector product, service life significantly
Extension.

Fig. 3 is the structural representation of plug.
Embodiment
Refering to Fig. 1, Fig. 2, Fig. 3, the present invention includes jack matrix 1, Spring capable of diameter varying 2, overcoat 3 and plug 4, the jack base
Body 1 be one end be provided with spring eye 11 cylindrical member, the Spring capable of diameter varying 2 be variable cross-section ring spring, its variable cross-section ring spring along axis according to
Secondary first grade that is provided with justifies the circle external diameter 24 such as external diameter 21, roundlet external diameter 22, variable cross-section external diameter 23, second and great circle external diameter 25, described
Overcoat 3 be nozzle provided with close up 31 tubular elements, the plug 4 is the cylindrical member that one end is provided with contact head, and its contact head is along axle
Line is sequentially provided with small column 41, cone cylinder 42 and waits cylinder 43；
The Spring capable of diameter varying 2 is in the spring eye 11 of jack matrix 1, and overcoat 3 is sleeved on the outside of jack matrix 1, and reducing bullet
The great circle external diameter 25 of spring 2 is connected between the end face of jack matrix 1 and the closing in 31 of overcoat 3；The contact head of plug 4 passes through overcoat
3 are plugged in Spring capable of diameter varying 2, and the small column 41 of plug 4, cone cylinder 42 and wait roundlet of the cylinder 43 respectively with Spring capable of diameter varying 2
The circle external diameter 24 such as external diameter 22, variable cross-section external diameter 23 and second is touched.
The internal diameter of described overcoat 3 is tight fit with the external diameter of jack matrix 1.
The termination of small column 41 is bulb on described plug 4.
Present invention assembling：
Refering to Fig. 1, Fig. 2, Fig. 3, Spring capable of diameter varying 2 is loaded to the spring eye of jack matrix 1 provided with one end that the first grade justifies external diameter 21
In 11, overcoat 3 is press-fitted mounted in the outside of jack matrix 1, and the great circle external diameter 25 of Spring capable of diameter varying 2 is connected to jack matrix 1
Between the closing in 31 of end face and overcoat 3；During grafting, the contact head of plug 4 is plugged in Spring capable of diameter varying 2 through overcoat 3, and inserted
First 4 small column 41, cone cylinder 42 and wait cylinder 43 respectively with the roundlet external diameter 22 of Spring capable of diameter varying 2, variable cross-section external diameter 23 and the
Second-class round external diameter 24 is touched.It is oriented to during for ease of grafting, present invention termination of small column 41 on plug 4 is provided with bulb.
The present invention is so used：
Refering to Fig. 1, Fig. 2, Fig. 3, because the present invention in jack matrix 1 using Spring capable of diameter varying 2 is provided with, when plug 4 and reducing
During 2 grafting of spring, the normal pressure in its each portion of plug 4 is broken down on the turn of the different-diameter of Spring capable of diameter varying 2, therebetween, plug 4
During preliminary insertion, plug 4 and Spring capable of diameter varying 2 are contactless, only when plug 4 small column 41 or wait cylinder 43 and Spring capable of diameter varying 2
The grade of roundlet external diameter 22 or second circle external diameter 24 just start stress, and roundlet external diameter 22 or second of Spring capable of diameter varying 2 etc. when touching
The turn of circle external diameter 24 also will not extend and shrink simultaneously, so, cause the contact engaging and separating force between plug 4 and Spring capable of diameter varying 2 to subtract
It is small, it is also corresponding to the frictional force that this is directly proportional to reduce, so as to change the present situation that conventional jack integrally replaces stress, it is not likely to produce
Fatigue, makes that the reliability of connector product is improved, service life is greatly prolonged.
Process its normal pressure from coil to coil of plugging together of plug 4 and the Spring capable of diameter varying 2 of the present invention is acted on Spring capable of diameter varying 2, is compared
For the state of conventional jack entirety stress, the smaller service life of abrasion of Spring capable of diameter varying 2 is higher and antifatigue, anti-vibration punching
Hit effect more preferable.
