Abstract
The utility model discloses a kind of improved wire spring plug bush, this wire spring plug bush comprises interior cover, overcoat and Duo Gen metal spring silk, outside the cover, forms the annulus between outer section of interior cover and the overcoat in overcoat is linked in; Cover and distribute in section places in each metal spring silk along interior cover inwall, outer section then folds in the described annulus, and and outer wall of inside race and outer casing inner wall between be interference fit.The utility model is simple in structure, and is easy for installation, and contact is good, and conduction is good.
Description
Technical field
The utility model relates to the improvement of the wire spring plug bush of electric connector.
Background technology
Wire spring plug bush is widely used in the electric connector.Common wire spring plug bush all be mostly earlier the metal spring filament winding after interior putting, fill in the lump then in the overcoat, more inside and outside cover crimping is got up.The wire spring plug bush of this structure is installed trouble on the one hand, is difficult on the other hand guarantee contact well between metal spring wire and the interior overcoat.
The utility model content
The purpose of this utility model just provides a kind of easy for installation, good wire spring plug bush of contact.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: this wire spring plug bush, comprise interior cover, overcoat and Duo Gen metal spring silk, and in being linked in, overcoat outside the cover, forms the annulus between outer section of interior cover and the overcoat; Cover and distribute in section places in each metal spring silk along interior cover inwall, outer section then folds in the described annulus, and and outer wall of inside race and outer casing inner wall between be interference fit.
As a kind of improvement, described overcoat outer end end is toward the axis direction bending, form internal diameter than the big annular flange flange of supporting contact pin external diameter.
Improve as another kind, described outer wall of inside race is three grades of stairsteppings that increase successively to the inner end diameter from the outer end; Outer section periphery of overlapping minimum one section of diameter in placing of metal spring silk; One section periphery in the middle of the cover in outer casing inner wall is placed in; The thickest one section external diameter of interior cover then equates with the overcoat external diameter.
As further improving, in the described interior cover metal stopper is arranged, section in each metal spring silk is pressed inside cover inwall.For the ease of overlapping in metal stopper is pushed and pressing inside cover inwall, described metal stopper is the ring taper.
During installation, in the metal spring silk is evenly arranged in around the cover inwall, one section periphery of cover diameter minimum in the outer section of metal spring silk then is folded into, firmly be inserted in overcoat and get final product this moment from minor diameter one end of interior cover, install very convenient.Better for interior cover and metal spring wire connection are touched, metal stopper is pushed interior cover inner end, and firmly knock with hard thing vacancy in metal stopper, enlargement deformation promptly takes place and makes the metal spring silk press inside cover hard in metal stopper.
Wire spring plug bush of the present utility model owing to being interference fit between section and interior cover, the overcoat outside the metal spring silk, has guaranteed that relative fixed also contacts well between the three; The annular flange flange that the overcoat outer end forms shelters from the bending place of each metal spring silk, is taken out of when the metal spring silk can not extracted by contact pin, also can not extracted by other external force; Outer wall of inside race is stairstepping, make behind the fit in the cylindrical of cover and overcoat concordant, outward appearance is succinctly attractive in appearance.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described in detail.
Fig. 1 is the structural representation of the wire spring plug bush of a kind of structure of the utility model.
Fig. 2 is the structural representation of the wire spring plug bush of the another kind of structure of the utility model.
Embodiment
As shown in Figure 1, the outer wall of interior cover 1 is stairstepping, and (i.e. right side the figure) (promptly among the figure left side) is from small to large three section 13,12 and 11 of diameter successively to the inner end from the outer end.In overcoat 2 is enclosed within outside cover 1 the medium and small two sections diameters 12,13 in outer end, the external diameter of overcoat 2 and interior cover 1 the thickest one section 11 external diameter equates or is approaching.The outer end of overcoat 2 to axis direction be bent to form internal diameter compare the supporting big slightly annular flange flange 21 of contact pin 4 external diameters.Cover 1 inwall in many metal spring silks 3 are evenly distributed on, 22 li of the annuluss that forms between outer section bending and insertion overcoat 2 and interior cover 1 reduced diameter section 13, and with overcoat 2 inwalls and in cover 1 reduced diameter section 13 outer wall interference fit, make overcoat 2, interior cover 1 and metal spring silk 3 fixing and closely couple together.The time easy for installation, guaranteed that contact is good.
As shown in Figure 2, parts different with Fig. 1 in the wire spring plug bush of this structure are that the metal stopper 5 of the thin ring taper in thick inner end, an outer end also is equipped with in the inner end of interior cover 1.After overlapping in 1 in metal stopper 5 is pushed into, firmly knock in the vacancy from metal stopper 5 with hard thing, can make metal stopper 5 generation enlargement deformation and make metal spring silk 3 press interior cover 1 inwall hard, thereby guaranteed that metal spring silk 3 contacts well with interior cover 1, conducts electricity well, thereby guaranteed that conduction is good between jack and the contact pin 4.
