Abstract
The utility model discloses an improved wire spring plugging sleeve in the electric connector, comprising an external sleeve, an internal sleeve and metal spring filaments. The inner segment of the internal sleeve is provided with a metal plug, which presses tightly the inner segment of the metal spring filaments towards the internal wall of the internal sleeve. The utility model has the advantages of simple structure, good contacting and fine conductivity.
Description
Technical field
The utility model relates to the improvement of the wire spring plug bush of electric connector.
Background technology
In connector, usually use wire spring plug bush.Existing most of wire spring plug bush all is that the interior cover that is wound with the metal spring silk is inserted in the overcoat, then inside and outside cover crimping is got up.The shortcoming of this jack be come in contact easily between spring wire and the interior overcoat bad, thereby make the loose contact of contact pin sleeve.
The utility model content
The purpose of this utility model provides a kind of good wire spring plug bush that contacts.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: this wire spring plug bush, comprise overcoat, interior cover and metal spring silk, and Duan Youyi metal stopper in the described interior cover, metal stopper inwardly overlaps inwall to the inner segment of each metal spring silk and compresses.
In cover in putting into, it is conical that described metal stopper is, and inner thin outer end is thick.
Make it contact closelyr with metal spring silk and interior cover inwall in order to make metal stopper be easy to deform, described metal stopper is done and is circularized.
The internal diameter of cover is bigger than the diameter of cover in one section of the outer end in this section at described metal stopper place.
As a kind of improvement, described overcoat be linked in described in the periphery of cover, form the slit of annular between outer section of interior cover and the overcoat; Inside cover inwall is pressed by metal stopper in arbitrary metal spring silk the inner, and the outer end then folds in the described annulus.
In order to make contact pin plug smooth and easy and to touch well with the metal spring wire connection, described arbitrary metal spring silk stage casing is curved, inwardly the axis bending of cover.The internal diameter that the oriented axis direction in described overcoat outer end end extends greater than the annular flange flange of supporting contact pin external diameter, form between this annular flange flange and the end, interior cover outer end and can supply the space of metal spring silk bending place activity.Cooperating between the part that described arbitrary metal spring silk folds into described annulus and outer wall of inside race and the outer casing inner wall is matched in clearance.
In the wire spring plug bush of the present utility model, metal stopper is the ring taper, is convenient to push in the jack on the one hand, on the other hand, overlaps the back in pushing and firmly knocks from the middle part with awl, can make the metal stopper distortion and tightly approach the metal spring silk and interior cover inwall.The diameter of this section jack at metal stopper place is bigger slightly than the diameter of the one section jack in outer end, guarantee metal stopper with in be locked connect airtight touch in, make metal stopper have enough space to produce distortion.Because each metal spring silk to the hole center curvature, when contact pin inserts, is pressed contact pin hard under the effect of elastic return, guaranteed to connect pin and contacted again with the good of metal spring silk.Between the outer section of each metal spring silk and the inside and outside cover be matched in clearance, and the space that forms between the annular flange flange at end, overcoat outer end and the end, interior cover outer end, and each spring wire can be in certain spatial movement in the contact pin insertion and when extracting, thereby it is smooth and easy that contact pin is plugged.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of wire spring plug bush of the present utility model.
Fig. 2 is the structural representation of metal spring silk.
Embodiment
As shown in Figure 1, the periphery of the interior cover 1 of wire spring plug bush terminal with overcoat 2 between form annulus 12, in the outer section invagination slit 12 of many metal spring silks 4 arranged side by side, and with interior cover 1 outer wall and overcoat 2 inwalls between to cooperate be matched in clearance.End, overcoat 2 outer end is bent to form annular flange flange 21 to the axle center, the internal diameter of annular flange flange 21 greater than the external diameter of supporting contact pin 3, form the space 13 that can move for metal spring silk 4 bending places between it and the end, interior cover 1 outer end.The middle part of each metal spring silk 4 distributes along the inwall of interior cover 1, overlaps 1 li section in inner segment arrives and is pressed inside cover inwall by metal stopper 5.This metal stopper 5 is the ring taper, and the outer end is thick inner thin, be convenient to make its from 1 mouthful in interior cover push and from stopper the vacancy knocked distortion and press hard in cover 1.The diameter of cover 11 is bigger slightly than the diameter of the outer section of interior cover in this section at metal stopper 5 places, makes metal stopper 5 outsides certain space be arranged to produce distortion, guarantees that metal spring silk 4 closely contacts with interior cover 1 inwall.As shown in Figure 2, metal spring silk 4 stage casings are curved, inwardly overlap 1 axis direction bending.When overlapping 1 in contact pin 3 insertions, metal spring silk 4 stage casings are pressed, and under the effect of elastic return, make it to contact pin 3 close proximity, have guaranteed to contact with the good of contact pin 3, contact well thereby make between contact pin 3 and metal spring silk 4 and the interior cover 1, and conductivity is good.On the other hand, because between each metal spring silk 4 outer section and the inside and outside cover 1,2 is matched in clearance, and forming between interior overcoat 1,2 ends can be for mobile within the specific limits space 13, metal spring silk 4 bending places, each metal spring silk 4 has certain activity space when contact pin 3 inserts, thereby makes contact pin 3 plugs all very smooth and easy.
Certainly, the utility model is also applicable to the line spring abutment with jacket structure form in other, so long as utilize metal stopper that metal spring silk and interior cover are compressed, all should be protection range of the present utility model.
