AI Technical Summary
In the existing technology, the assembly of the hairspring assembly requires two processes and two components, resulting in high costs and low production efficiency.
It adopts an integrated hairspring assembly, with the hairspring directly fixed on the hairspring holder. The hairspring holder has the function of a bushing and integrates a second conductive component, reducing the number of parts and assembly processes.
The integrated design reduces the number of parts and assembly steps, lowers costs and improves production efficiency, while also increasing product precision and lifespan.

Abstract
Claims
1. An integrated hairspring assembly, characterized in that, include: gossamer; A hairspring holder includes a shaft, on which a first boss and a second boss are integrally formed. The first boss and the second boss are arranged parallel to each other and form a connecting groove between them. The hairspring is fixedly installed in the connecting groove. The first boss is located in the middle of the shaft and forms a first stepped surface with the shaft. The first stepped surface is suitable for abutting against and assembling a second conductive component.
2. An integrated hairspring assembly as claimed in claim 1, characterized in that The depth of the connecting groove is greater than the radial protrusion height of the first boss or the second boss.
3. An integrated hairspring assembly as claimed in claim 1, characterized in that The width of the connecting groove is greater than the width of the hairspring. After the hairspring is fixed in the connecting groove, gaps are formed between the upper and lower sides of the hairspring and the connecting groove.
4. An integrated hairspring assembly as claimed in claim 1, characterized in that The hairspring is fixed in the connecting groove by riveting or welding.
5. An integrated hairspring assembly as claimed in claim 1, wherein, The second boss is also provided in the middle of the shaft body, and the second boss and the shaft body form a second stepped surface.
6. The integrated hairspring assembly as described in claim 1, characterized in that, The first boss and the second boss have the same outer diameter and the same thickness.
7. An integrated hairspring assembly as claimed in claim 1, wherein, The first boss and the second boss are symmetrically arranged on the shaft.
8. An electrical contact device, comprising: First conductive component; A connector, wherein the first conductive component is fixedly disposed on the connector, characterized in that an integrated hairspring assembly as described in any one of claims 1 to 7 is rotatably disposed on the connector, the second conductive component is fixedly disposed on the integrated hairspring assembly, and the connector is provided with limiting structures at both ends to axially limit the first conductive component and the integrated hairspring assembly.
9. An electrical contact as claimed in claim 8, wherein the contact element is formed from a material having a hardness of at least 8 on the Mohs scale. The limiting structure includes a stop integrally formed at one end of the connector, and the other end of the connector limits the first conductive component by riveting or by using a snap ring.
10. An electrical contact device as claimed in claim 9, characterised in that An insulating film is provided between the first conductive component and the hairspring holder, and an insulating washer is provided between the hairspring holder and the stop.
