Detailed description of the invention
The enforcement of a kind of electric connector is such as shown in Fig. 2 ~ 5: include jack, jack includes spring body and axis extends along the longitudinal direction inner sleeve and overcoat 5, and inner sleeve, overcoat all adopt overall structure, the front end of overcoat 5 to be inserted terminal.Overcoat includes coat body 14, and the endoporus of coat body 14 is shoulder hole structure, and shoulder hole structure includes diameter holes section 17, central diameter hole section 15 and big hole, the footpath section 12 that diameter from front to back becomes larger.Inner sleeve includes internal sleeve noumenon 6, the outer peripheral face of internal sleeve noumenon 6 is multidiameter structure, the outer peripheral face of multidiameter structure includes the big footpath shaft part 61 being positioned at middle part and the path shaft part 62 being positioned at shaft part 61 both sides, big footpath, the wherein size fit of big footpath shaft part 61 and central diameter hole section 15, spring body includes the cylindrical coil spring silk 3 of 60 circumferentially spaced layouts, the front end face of internal sleeve noumenon is provided with and coil spring silk coil spring silk front limit groove 18 one to one, the rear end face of internal sleeve noumenon is provided with coil spring silk one to one coil spring silk after stopper slot 19, the front end of each coil spring silk has the outer front overhanging structure 2 turning to outside inner sleeve and overhanging backward, the rear end of each coil spring silk has the outer rear overhanging structure 9 turning to outside inner sleeve and overhanging forward, before, rear overhanging structure is in the path shaft part 62 of correspondence.Before same coil spring silk, rear overhanging structure is respectively radially by corresponding coil spring silk front limit groove, stopper slot traverse after coil spring silk, deviate mutually in a circumferential direction corresponding to stopper slot after coil spring silk front limit groove and the coil spring silk of same coil spring silk, namely coil spring silk front limit groove is staggeredly arranged with stopper slot projection in the axial direction after corresponding coil spring silk, a pair coil spring silk stopper slot is become corresponding to stopper slot after coil spring silk front limit groove and the coil spring silk of same coil spring silk, so make coil spring silk can form certain angle excursion with the centrage of inner sleeve, ensure the reliable grafting of coil spring silk and corresponding contact pin.Equipped with the inner sleeve 6 of spring body by rear to the front central diameter hole section 15 being encased in shoulder hole structure and hole, big footpath section 12 during use, the step surface between diameter holes section 17 with central diameter hole section 15 constitutes and coordinates to limit spring body and inner sleeve moves forward the front block step 16 of the limit for spacing with front overhanging structure.Hole, big footpath section forms the annular installation cavity of overhanging structure peripheral after being positioned at, annular installation cavity is coordinated with inner sleeve and to the fixing fixed cover 8 of rear overhanging structural clamp, the step surface composition between the section of hole, Duan Yu great footpath, central diameter hole is used for coordinate spacing with fixed cover moving the rear block step 13 of the limit forward limiting fixed cover from rear to front being incorporated with.The inner hole wall of coat body is provided with thread segment 11 in the rear side of annular installation cavity, on thread segment 11, screw thread is installed with stop nut 10, stop nut 10 includes the thread segment with coat body threaded engagement and is arranged at the baffle plate of thread segment front end, and baffle plate coordinates thus limiting fixed cover, inner sleeve and spring body and moving backwards with fixed cover, rear overhanging structure block.The inner hole wall of coat body is provided with spring touch finger 1 in the front side of spring body, realizes conduction by the cooperation of spring touch finger and each coil spring body, it is ensured that through-current capability.
When assembling, before first each coil spring silk is assembled to the coil spring silk of correspondence, in rear stopper slot, before the coil spring silk of every pair of coil spring silk stopper slot, rear stopper slot is circumferentially offset with one another (namely before the coil spring silk of every pair of coil spring silk stopper slot, the centrage of rear stopper slot is in a certain angle), therefore each coil spring silk can produce radially gathering power, when with adaptive contact pin to slotting use, coil spring silk and contact pin produce radial direction chucking power thus ensureing reliable contacts, before coil spring silk, each coil spring silk is defined spacing by the use of rear stopper slot, ensure that coil spring silk will not produce mobile, also a fairly large number of coil spring silk is made to be assembled into possibility, ensure that the through-current capability of product.After front overhanging structure is by front block step block, being encased in annular installation cavity by fixed cover by rear to front, subsequently by stop nut spinning in the endoporus of coat body, complete assembling, whole assembling process is simple and convenient, and efficiency of assembling is greatly improved.
In other embodiments of the invention: the number of coil spring silk can also be configured as required, for example, 10,20,35 etc.；Spring touch finger can not also set；Spring body can also adopt the structure of hat spring formula；Stop nut can also be replaced by other the locating part being capable of fixed cover and inner sleeve are carried out block spacing by some, such as is installed on the jump ring on outer casing inner wall；Certainly, when the interference power between fixed cover and overcoat and rear projecting end, inner sleeve can ensure that inner sleeve is not moved after the meeting, locating part can not also set；Spacing fixing to front extended structure can also adopt the fixed form being similar to rear extended structure, such as annular installation cavity is set in the periphery of front extended structure on the inwall of overcoat, then by a fixed cover being inserted in annular installation cavity from front to back, thus what realize front extended structure is fixing.
The enforcement of jack is such as shown in Fig. 2 ~ 5: the concrete structure of jack is identical with the jack described in above-mentioned each adapter embodiment, is not described in detail in this.
The enforcement of inner sleeve is such as shown in Fig. 2 ~ 5: the concrete structure of inner sleeve is identical with the inner sleeve described in above-mentioned each adapter embodiment, is not described in detail in this.
