Abstract
The utility model relates to a novel electric contact jack which is composed of a jack main body, a weld zone and a jack zone. The jack zone and the weld zone are respectively arranged on the front end and the back end of the jack main body. The jack zone is provided with a grooving zone along the axial direction of the jack main body. The inner cavity of the jack zone is divided into a contact zone and a deep hole zone in a stepped manner. The dimension of the inner hole of the deep hole zone is greater than the dimension of the inner hole of the contact zone. The jack zone of the jack is combined by the contact zone and the deep hole zone, which are arranged in a stepped manner. The contact zone is fully utilized for large-area cylindrical contact of plugging between the jack and a pin. Moreover, the deep hole zone is utilized for correction of a concentricity deviation of plugging between the pin and the jack. The jack is simple in structure, is favorable for stable plugging of the pin, is fine in plugging performance, and enables the service life of both the pin and the jack to be prolonged.
Description
Technical field
The utility model relates to a kind of structure that electrically contacts jack, relates in particular to a kind of adaptive and circular structure that electrically contacts the jack of contact pin when plugging together.
Background technology
The version of traditional electrical contact chip spring socket (hereinafter to be referred as jack) is shown in figure (1): perforate φ D is with adaptive contact pin on the jack main body; φ D is generally than nominal dimension+0.18+0.13 of adaptive contact pin φ E; The contact pin excircle dimension is on the basis of its nominal dimension φ E-0.01-0.03; Fluting forms the sheet spring so that close up.Jack contact endoporus φ D and adaptive contact pin cylindrical φ E form the purpose in gap: prevent contact pin, plug together decentraction and cause that the sheet spring excessively struts and lost efficacy owing to inevitable process deviation causes when jack plugs together.
From Fig. 2,3, can find out, after the closing in, cause dwindling of endoporus φ D, see from virtual condition, the endoporus that the interior R arc of two springs forms after closing in has been oval.
After the closing in timeliness, not enough below the state after plugging together with contact pin exists:
1, contacts the contact of not formation face: because the gap between Socket bore φ D and the contact pin cylindrical φ E reaches 0.13～0.18; After the closing in; The inner hole surface of Socket bore φ D can not contact with the periphery formation face of contact pin φ E, can only on this line of cylindrical line mouth of cross section, A-A place, form contact.
2, contacting efficiency is low: because the existence in gap between contact pin cylindrical φ E and the Socket bore φ D; R arc 7 can not coincide with the contact pin cylindrical well in the jack sheet spring; Form contact blind area 8 at nearly fluting end, from this point, the structure in sheet spring hole can only be a contact.
Can be found out that by above-mentioned analysis traditional sheet spring formula jack is easy to process, processing cost is low, but be the some contact, contact area is less, and contact resistance is bigger.
Summary of the invention
The utility model provides a kind of novel jack that electrically contacts; It overcome existing sheet spring electrically contact jack can not contact of formation face and the low defective of contacting efficiency; Form the contact of effective face of cylinder at contact pin, when jack plugs together; It is convenient, stable that contact pin and jack are pegged graft, and plugging capability is good, prolonged contact pin, jack useful life.
The technical scheme that the utility model adopts is: a kind of novel jack that electrically contacts; Form by jack main body, weld zone and jack district; Jack district and weld zone are located at the front-end and back-end of jack main body respectively; Have in the jack district along the jack body shaft to slotted zones, it is characterized in that said jack district inner chamber staged ecto-entad is divided into contact zone and deep hole district, the interior hole dimension in deep hole district is greater than the interior hole dimension of contact zone.
Further, said bearing length is less than slotted zones length.
Further, the length+1mm of the length=contact zone in said deep hole district.
Further, the length of said slotted zones=jack section length-1mm.
Again further, to going deep into the direction symmetrical grooving, groove width 0.5～0.6mm slots several 2～4 to said slotted zones by the weld zone insertion end.
The formation in this jack deep hole district effectively guarantees Concentricity tolerance and the effective elasticity life-span that guarantees reed when calibration contact pin and jack plug together, and slotted zones is the closing in of reed for the benefit of, guarantees the normal pressure of contact zone reed to contact pin.Because of the contact zone is positioned at jack foremost, get into contact condition when plugging together at first, thereby increased contact length effectively with contact pin, that is to say to have increased contact area, improved the plugging capability of jack; Can effectively control the length of contact pin in addition, thus reduce the outer damage contact pin causes owing to contact pin is long maybe, help preventing oblique cutting, prolongation contact pin, jack useful life.
The jack district of the utility model jack is the staged contact zone and the deep hole district combines; Make full use of the contact zone and realize that jack contacts with big territory of cylinder that contact pin plugs together; And the calibration of the Concentricity tolerance when utilizing the deep hole district to realize that contact pin and jack plug together, jack structure is simple, helps the stable grafting of contact pin; Plugging capability is good, has prolonged contact pin, jack useful life.

Among the figure: jack main body 1, jack district 2, weld zone 3, slotted zones 4, contact zone 5, deep hole district 6.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Shown in Figure 4, a kind ofly novelly electrically contact jack and comprise jack main body 1, jack district 2 and weld zone 3; Jack district 2 and weld zone 3 are located at the forward and backward two ends of jack main body 1 respectively; Have in the jack district 2 along the axial slotted zones 4 of jack main body 1, slotted zones by the weld zone insertion end to going deep into the direction symmetrical grooving, groove width 0.5～0.6; It is several 2～4 to slot, the length of slotted zones=jack section length-1mm; Jack district 2 inner chamber staged ecto-entads are divided into contact zone 5 and deep hole district 6, and the interior hole dimension in deep hole district 6 is greater than the interior hole dimension of contact zone 5, and bearing length is less than slotted zones length, the length+1mm of the length=contact zone in deep hole district.
When contact pin, when jack plugs together, contact pin can contact by formation face with the contact zone in jack district, stops point, line contact, and contact area is big; Contact pin inserts in the deep hole district, and the decentraction of effectively offsetting processing technology deviation, the caused contact pin of assembling deviation, jack plugs together the influence that brings.
The utility model has reduced the contact resistance of contact pin and jack to greatest extent, realizes low resistance contact, in case contact resistance significantly reduces; List will rise to contact pin, the right carrying rated current of jack contact, and the ampacity of the whole connector under the equal core spectrum density will increase, and the anti-current impact capacity strengthens; Improve reliability, contact descends to the heating power under certain current condition, reduces its temperature rise; Improve the life-span; Under the constant situation of current capacity, can increase the core spectrum density, in sum, the technological improvement of the utility model is significant to the right influence of whole contact.
