The characteristics of leaning on, saving space.Technical high cost investment limits high-speed transmission connector and develops to high integration direction.
The electrical contact components such as coil spring hole, hat spring hole, brush contact and the twist needle of the prior art, manufacture difficulty is high, assembling
Complex process, reliability are influenced very big by process equipment and condition.
Utility model content
A kind of micro- spring socket that the purpose of this utility model is in view of the deficiencies of the prior art and designs is in electrical contact component, adopts
The needle body that helical groove structure is embedded in micro- spring is connect with sleeve riveting, and Microspring is made to be clamped in the gap of sleeve and needle body,
Flange is contacted with the butt end needle body of insertion, is stepped down, while not losing elasticity again, is improved by the deflection and deformation of Microspring
It is in electrical contact high reliability, simple in structure, easy to assembly, manufacturing cost is low, significantly improves circuit performance.
What the purpose of this utility model was realized in：A kind of micro- spring socket electrical contact component, its main feature is that the contact group
Part is formed by sleeve and the needle body riveting equipped with Microspring, and described needle body one end is the jack equipped with helicla flute, and the other end is to set
There is the welding ends of the shaft shoulder；The helicla flute is the notch of " D " tee section, and small end notch penetrates jack；The Microspring insertion
In the helicla flute of needle body, and outer rim protrusion is in jack；Sleeve one end is equipped with guide angle, and the other end is equipped with and turns over riveting knot
Structure turns over riveting knot structure by sleeve and needle body riveting into electrical contact component.
The utility model has reliability high compared with prior art, and simple in structure, easy to assembly, manufacturing cost is low, easily
It is efficient in implementation micro-production, electrical contact performance is substantially improved, the needs of product structure layout are greatly met, it can
It is widely used in little profile, the solution of half step distance, high density and high speed data transfers component.

Specific implementation mode
Refering to 1~Fig. 2 of attached drawing, riveting forms after the utility model is set with by sleeve 1 with the needle body 3 equipped with Microspring 2, institute
It states Microspring 2 to be arranged in the helicla flute 31 of " D " type groove mouth of needle body 3, is connected with each other after needle body 3 and 2 riveting of sleeve, makes micro- bullet
Spring 2 ensures the contact assembly for being in close contact and being formed a separate unit to each other without device for elimination of axial-and radial-play.
Refering to attached drawing 3,3 one end of the needle body is the jack 34 equipped with helicla flute 31, and the other end is the weldering equipped with the shaft shoulder 32
Connect end 33；The helicla flute 31 is the notch of " D " tee section, and small end notch penetrates jack 34；" D " of the helicla flute 31
Shape notch had both contained Microspring 2, again limits Microspring 2 and runs out of notch inner wall；The shaft shoulder 32 is fixed with pedestal for component
Position fixing；The welding ends 33 is for system PCB welding.
Refering to 4~Fig. 5 of attached drawing, 1 one end of the sleeve is equipped with guide angle 11, and the other end is equipped with and turns over riveting knot structure 12, described to turn over
It is in close contact after riveting knot structure 12 and 3 riveting of needle body, and locking needle body 3 prevents sleeve 1 and needle body 3 from mutually axially moving.
Refering to 6~Fig. 7 of attached drawing, the Microspring 2 is wrapped on the jack 34 of needle body 3, and is embedded in " D " of helicla flute 31
In shape notch.
Refering to attached drawing 8, the sleeve 1 is sleeved on 34 one end of jack of needle body 3, and by turning over riveting knot structure 12 by sleeve 1 and needle
3 riveting of body connects into electrical contact component, and the small thin of 2 both ends of Microspring can be clamped in the gap of 1 inner wall of the sleeve and needle body 3
Silk, makes Microspring 2 be positioned between sleeve 1 and needle body 3, ensure that the contact between sleeve 1 and Microspring 2 and needle body 3, simultaneously
1 inner wall of sleeve oppress Microspring 2 outer rim 21 31 inner wall of helicla flute close to and protrude in jack 34.
Refering to attached drawing 9, by the jack 34 to being inserted into needle body 3 with end contact pin 4, the Microspring 2 being wrapped in helicla flute 31 is justified
Torsion or the freely-supported of positive compression provide elastic force after ring deflection, the outer rim 21 of Microspring 2 provide with to the contact for holding needle body 4
Region, this contact area can provide Multi-contact, and outer rim 21 is contacted with the butt end needle body 4 being inserted into, and passes through Microspring 2
Deflection is stepped down with deformation, while not losing elasticity, and Redundant contact is more, improves electrical contact high reliability.
Above to be only further described to the utility model, not to limit this patent, all is the utility model
Equivalence enforcement is intended to be limited solely by within the right of this patent.
