Description

Technical Field

[0001] The utility model relates to the technical field of wind power slip rings, in particular to an assembled slip ring. Background Art

[0002] Rotating conductive connections are essential components in modern electronic devices and mechanical systems, particularly in applications where power or signal transmission requires relative rotation between components, such as rotating platforms, automated production lines, rotary sensors, and rotating components in aerospace equipment. Traditional rotating conductive connections often utilize slip rings or carbon brushes, but these structures suffer from high contact resistance, severe wear, high maintenance costs, and limited lifespans.

[0003] To overcome the shortcomings of traditional rotating conductive connection technology, modular slip rings have emerged as an innovative solution. Through a modular design, modular slip rings separate the moving and stationary rings, reliably connecting them via specific connectors. This allows the moving ring to rotate freely within the stationary ring, enabling continuous and stable transmission of power or signals. However, existing modular slip rings still have some structural design deficiencies, such as insufficient housing connection strength, prone to longitudinal displacement of the moving ring, and insufficient connector elasticity leading to difficulties in installation and maintenance. These issues limit the application range and performance of modular slip rings. Utility Model Content

[0032] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1

[0034] This embodiment provides an assembled slip ring, the structure of which is as follows: Figures 1 to 5 As shown, it mainly includes a dynamic ring body 1, a static ring body 2, a connecting piece 3 and a fixed sleeve 4.

[0035] The rotating ring body 1 is designed with an outwardly protruding conductive ring 11 on its outer side. This conductive ring 11 is made of a highly conductive material to ensure good current transmission performance. Conductive rings 11 are evenly distributed along the circumference of the rotating ring body 1 and are used to maintain continuous contact with the contact arms (not shown in the figure, but located inside the stationary ring body 2 and cooperating with the conductive rings 11) during rotation, forming a dynamic conductive path.

[0036] The stationary ring body 2 is a hollow structure that fits over the outer surface of the dynamic ring body 1. It is composed of two symmetrical outer shells 21 assembled in a specific manner. A cavity 22 is formed between the two outer shells 21 to accommodate the dynamic ring body 1 and allow it to rotate freely. The outer shells 21 are constructed of a plastic or metal with a certain strength and toughness to ensure structural stability and durability.

[0037] The connector 3 is a key component connecting the two housings 21. Its unique design features an elastic portion 32 in the middle, allowing the two housings 21 to stretch outward relative to each other within a certain range to accommodate installation or maintenance needs. Each end of the connector 3 features a head 31 that fits into a recess 211 pre-set on the housing 21, ensuring a secure connection that resists loosening. The head 31 also features a stop 311, which can be a partially thickened portion or an additional raised structure. This serves to increase the strength of the connection when the housings are stretched, preventing the connector from falling off due to external forces.

[0038] The fixing sleeve 4 is mounted on the outside of the static ring body 2. Its main function is to strengthen the structure of the static ring body 2 and prevent it from deforming due to uneven force during operation. The material of the fixing sleeve 4 matches the shell 21 to ensure the stability and reliability of the overall structure.

[0039] Furthermore, to improve the rotational stability of the dynamic ring body 1 within the cavity 22 and prevent its longitudinal displacement, baffles 23 extending inward are provided at the top and bottom of the cavity 22. These baffles 23 not only serve as position limiters but also reduce friction between the dynamic ring body 1 and the static ring body 2 to a certain extent, thereby extending their service life.

[0040] Regarding the specific implementation of the elastic portion 32, in this embodiment, a spring is preferably used as the elastic element because it has good elasticity and recovery properties and can meet the requirements of relative stretching and resetting of the housing 21. Of course, depending on the actual situation, the elastic portion 32 can also be made of elastic materials such as silicone, rubber, or a combination thereof to achieve similar effects.

[0041] In particular, in this embodiment, the housing 21 has four grooves 211, located at the four corners of the housing 21. This design ensures connection stability while facilitating processing and installation. The interference fit between the head 31 of the connector 3 and the grooves 211 ensures the integrity and robustness of the stationary ring body 2 after assembly.

[0042] In summary, the assembled slip ring provided in this embodiment realizes reliable connection and flexible rotation between the dynamic ring body and the static ring body through ingenious structural design, while ensuring good conductivity and structural stability, and is suitable for various occasions requiring rotating conductive connection.

[0043] Example 2

[0044] like Figure 6 As shown, the difference from Example 1 is that, in order to facilitate the positioning effect and stability when the two shells 21 are assembled, a magnetic ring 5 is also embedded around the groove 211, and the magnetic rings 5 embedded in the adjacent grooves of the two shells 21 are attracted to each other, thereby ensuring the stability of the dynamic ring body.

[0045] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content sought to be protected by the present invention is fully set forth in the claims.
