Description

Technical Field

[0001] This utility model relates to the field of power connector technology, specifically a rotary power connector. Background Technology

[0002] Power connectors are interface devices used to transmit electrical energy between electrical equipment and power sources. They are widely used in consumer electronics, industrial equipment, communication systems, medical instruments, new energy, and many other fields to ensure safe and stable power transmission. Rotary power connectors allow one component to rotate continuously relative to another while maintaining the transmission of power and signals.

[0003] Existing rotary power connectors typically only allow for rotation of the socket or the housing during use, and the rotation is limited to a flat surface, thus restricting the rotation angle and making them unsuitable for various operating environments. Utility Model Content

[0004] The purpose of this utility model is to provide a rotary power connector to solve the problem mentioned in the background art that currently available rotary power connectors on the market can only be adjusted by rotating the socket or rotating the shell, and can only be rotated on a plane, which limits the rotation angle and makes them unsuitable for various usage environments.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary power connector, comprising a power connector body, a housing on the power connector body, and an inherent inner partition support seat snapped into the housing. A bearing seat is fixed above the inner partition support seat, and a rotary socket is installed inside the bearing seat. A conductive female plug is embedded in the rotary socket, and a conductive ring is fixedly installed below the rotary socket. A brush is movably installed on the outer ring of the conductive ring. A positioning seat is provided below the power connector body, which movably engages with the housing. A protrusion is integrally provided on the bottom of the housing. The bottom of the protrusion structure of the housing is provided with evenly spaced toothed grooves, and a matching worm gear is provided at the bottom of the toothed grooves. The brush is securely installed inside the housing and is electrically connected to a power line. An inherent hollow rotary connecting shaft is snapped between the positioning seat and the housing, and the power line passes through the hollow rotary connecting shaft, allowing the housing to deflect, while the rotary socket rotates under the positioning of the housing.

[0006] Preferably, the part of the rotating socket that engages with the outer shell has a stepped structure, and a sealing element that is fastened to the outer shell is fitted onto the stepped structure of the rotating socket.

[0007] Preferably, heat dissipation fins are installed on the bottom of the outer shell inside the positioning seat, and folded heat dissipation and dustproof mesh plates are fixed on both sides of the outer shell and the positioning seat.

[0008] Preferably, the toothed grooves are distributed with the hollow rotating connecting shaft as the center, and the toothed grooves are located on both sides of the heat dissipation fins.

[0009] Preferably, the worm gear is rotatably installed in the positioning seat, and the bottom of the positioning seat is also provided with a tightening bolt that is fastened to the worm gear.

[0010] Preferably, the bottom of the positioning seat is a planar structure, and the side of the positioning seat is symmetrically provided with integrally formed fixing holes.

[0011] Compared with existing technologies, the advantages of this utility model are: In addition to the rotation of the socket portion, the rotating power connector also allows for a certain angle of deflection adjustment of the outer shell used for socket rotation positioning, increasing the rotation adjustment range of the socket and making the power connector more versatile. This rotating power connector uses a U-shaped positioning seat for basic positioning, and a meshing toothed groove and worm gear are provided between the positioning seat and the outer shell. Rotation of the outer shell drives the toothed groove to move, which in turn drives the worm gear to rotate. Therefore, when locking the outer shell after rotation is required, the worm gear can be locked, while the outer shell can move within a certain range when the worm gear is not locked.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a rotary power connector, including a power connector body 1, a housing 5 on the power connector body 1, and an inner partition support 502 snapped into the housing 5. A bearing seat 4 is fixed above the inner partition support 502, and a rotary socket 3 is installed inside the bearing seat 4. A conductive female plug 303 is embedded in the rotary socket 3, and a conductive ring 301 is fixedly installed below the rotary socket 3. A brush 302 is movably installed on the outer ring of the conductive ring 301. A positioning seat 8 is provided below the power connector body 1, which movably engages with the housing 5. A protrusion is integrally provided on the bottom of the housing 5. The part where the rotary socket 3 engages with the housing 5 is provided with a stepped structure. A sealing element 2, which is fastened to the outer shell 5, is fitted at the stepped structure. This structure provides sealing protection when the rotary socket 3 is rotatable. The stepped structure of the rotary socket 3 also enhances the sealing structure. The bottom of the protruding structure of the outer shell 5 is evenly spaced with toothed grooves 501, and a matching worm gear 6 is provided at the bottom of each toothed groove 501. The toothed grooves 501 are distributed around the hollow rotating connecting shaft 802 as the center and are located on both sides of the heat dissipation fins 10. When the outer shell 5 rotates relative to the positioning seat 8 via the hollow rotating connecting shaft 802, the toothed grooves 501 rotate synchronously. At this time, the toothed grooves 501, through their cooperation with the worm gear 6, enable the rotation of the worm gear 6. The housing 5 is installed inside the positioning seat 8, and the bottom of the positioning seat 8 is also connected to a tightening bolt 803 that is fastened to the worm gear 6. This structure, by tightening the worm gear 6, can achieve the locking treatment of the tooth groove 501, ensuring the stability of the housing 5. This allows the housing 5 to be tightened after being adjusted to the required angle. By making the housing 5 rotatable, the range of motion of the rotary socket 3 is increased, thereby adapting to more usage needs. The brush 302 is fastened inside the housing 5 and is electrically connected to the power cord 7. The bottom of the housing 5 is fitted with heat dissipation fins 10 inside the positioning seat 8, and folded heat dissipation and dustproof mesh plates 9 are fixed on both sides of the housing 5 and the positioning seat 8. This structure can increase the heat dissipation of the power connector body 1. When the rotating socket 3 rotates multiple times in a short period of time, a large amount of heat will be generated. The heat dissipation fins 10 can effectively dissipate heat. At the same time, the folded heat dissipation and dustproof mesh plate 9 can reduce dust from entering the positioning seat 8 while dissipating heat. The positioning seat 8 and the outer shell 5 are locked together with the hollow rotating connecting shaft 802, and the power cord 7 passes through the hollow rotating connecting shaft 802, so that the outer shell 5 can be deflected. The rotating socket 3 rotates under the positioning of the outer shell 5. The bottom of the positioning seat 8 is a flat structure, and the side of the positioning seat 8 is symmetrically provided with an integrally formed fixing hole seat 801. This structure allows the positioning seat 8 to be used for bottom support of the power connector body 1 and to be fixed through the fixing hole seat 801.

[0018] Working principle: When using this rotary power connector, firstly, when using the power connector body 1, the connector is fixed by inserting the conductive female plug 303 of the rotary socket 3. Under the installation and positioning of the housing 5, the rotary socket 3 is limited in rotation by the bearing seat 4. The conductive ring 301 and the brush 302 are always in contact to ensure the stability of the electrical connection. The seal 2 is used for sealing the rotary socket 3, and the inner partition support 502 is used for separating the rotary socket 3 and the power cord 7. If the angle of the housing 5 needs to be adjusted, with the tightening bolt 803 loosened, the housing 5 can rotate relative to the positioning seat 8 through the positioning of the hollow rotary connecting shaft 802. During rotation, the toothed groove 501 works in conjunction with the worm gear 6, causing the worm gear 6 to rotate as the housing 5 moves. The worm gear 6 is tightened by the tightening bolt 803, which can achieve the braking treatment of the housing 5 and ensure the stability of the housing 5. When the tightening bolt 803 is not tightened, the housing 5 can rotate under the restriction of the worm gear 6, ensuring that the housing 5 moves within a certain range, thereby increasing the rotation range of the power connector body 1. The positioning seat 8 can be bolted by the fixing hole seat 801. The housing 5 provides auxiliary heat dissipation treatment for the power connector body 1 through the heat dissipation fins 10, and dissipates heat through the folded heat dissipation and dustproof mesh plate 9, thus completing a series of operations.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
