In this specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of this utility model with reference to the accompanying drawings is intended to explain the overall inventive concept of this utility model and should not be construed as a limitation thereof.

[0023] The terms “comprising,” “including,” and similar terms as used herein should be understood as open-ended terms, meaning “including / including but not limited to,” implying that other content may also be included. The term “based on” means “at least partially based on.” The term “one embodiment” means “at least one embodiment”; the term “another embodiment” means “at least one additional embodiment,” and so on.

[0024] As mentioned earlier, existing rotary connectors cannot prevent dust from entering the electrode interior. Dust adhering to the electrode surface can cause equipment malfunctions or short circuits during use, reducing product safety. To address these issues, this invention proposes a dustproof rotary connector assembly that effectively prevents external dust from entering the electrode area and contacting conductive components, ensuring the safety and stability of the rotary connector assembly.

[0025] The following will take the exemplary dustproof tail connection component of this utility model as an example for detailed explanation.

[0026] Combined with reference Figures 1 to 4An exemplary dustproof tail connector assembly 100 includes a tail body 10 and a tail socket 20 that mates with the tail body 10. For example... Figure 2 As shown, the tailpiece body 10 includes a power cord 11, a conductive element 12, a support element 13, and an insulating element 14. The conductive element 12 forms an electrical connection with one end of the power cord 11 to receive electrical power. The support element 13 is disposed adjacent to the conductive element 12 and configured to support the conductive element 12, thereby keeping the conductive element 12 stable in the axial direction and preventing wobbling during insertion and removal of the conductive element 12. In one embodiment, the support element 13 is injection molded and can be made of a rigid plastic material such as reinforced nylon, or other materials with high hardness, good insulation, and wear resistance.

[0027] like Figure 2 As shown, the support member 13 also includes an annular stepped portion 131, and the insulating member 14 is disposed on the stepped portion 131. In one embodiment, the insulating member 14 is fixedly installed to the stepped portion 131 by an interference fit, or the insulating member 14 can be assembled to the stepped portion 131 by other suitable methods.

[0028] The swivel socket 20 includes a housing 21 and a conductive connection assembly 22. In one embodiment, the socket housing 21 can be assembled to the swivel body 10 by interference fit, or by snap-fit ​​or other suitable means. When the swivel body 10 is connected to the swivel socket 20, the housing 21 at least partially accommodates the swivel body 10, and the housing 21 cooperates with the insulating member 14 to form an insulating space 17. The insulating space 17 can prevent dust from the outside of the dustproof swivel connection assembly 100 from contacting the conductive member 12, ensuring the safety of the internal electrical connection of the swivel connection assembly 100. In one embodiment, the insulating member 14 can be an iron ring with a smooth outer surface, which can reduce the friction between the insulating member 14 and the housing 21, allowing the swivel body 10 to rotate within the socket housing 20. In other embodiments, the insulating member can also be made of other materials with high hardness, low coefficient of friction, and wear resistance.

[0029] The conductive connection assembly 22 is at least partially disposed within the socket housing 21, and the conductive connection assembly 22 can contact the conductive element 12 to form an electrical connection. When the conductive connection assembly 22 is connected to a load (not shown), the conductive connection assembly 22 can provide the electrical power received by the conductive element 12 to the load.

[0030] In one embodiment, the dustproof tail connector assembly 100 further includes a stress relief element 15. The stress relief element 15 at least partially encloses the power cord 11 to reduce stress bending of the power cord 11 and prevent problems such as breakage or damage during long-term use. In one embodiment, the stress relief element 15 may be made of a soft plastic material such as thermoplastic polyurethane, or other materials with good insulation, abrasion resistance, and bending resistance.

[0031] In one embodiment, the dustproof tailpiece connection assembly 100 further includes an injection-molded body 16, which is at least partially disposed within the stress relief member 15. The injection-molded body 16 is injection-molded at the bend of the power cord 11, further relieving stress on the power cord 11 and thereby improving the vibration resistance and durability of the tailpiece body 10. In one embodiment, the injection-molded body 16 may be made of reinforced nylon, or other materials with good insulation and abrasion resistance may be used.

[0032] In one embodiment, the conductive element 12 includes a conductive post 121 and an annular conductive portion 122. The annular conductive portion 122 is spaced around the conductive post 121 and arranged coaxially with it. In one embodiment, the conductive post 121 and the annular conductive portion 122 may be made of copper, or other materials with good conductivity and wear resistance. In one embodiment, the conductive post 121 may be a copper needle, and the annular conductive portion 122 may be a copper ring.

[0033] In one embodiment, the conductive connection assembly 22 includes a conductive connector 221 and a connection terminal 222. When the tailpiece body 10 is connected to the tailpiece socket 20, the conductive connector 221 contacts the conductive post 121 and the annular conductive portion 122 to form an electrical connection. One end of the connection terminal 222 is connected to the conductive connector 221, and the other end is connected to a load (not shown) and configured to provide electrical power to the load. In one embodiment, both the conductive connector 221 and the connection terminal 222 may be made of copper or a copper alloy, or other materials with high hardness, good conductivity, and wear resistance may be used. In one embodiment, the conductive connector 221 may be connected to the connection terminal 222 by a variety of suitable methods, such as riveting, rivet connection, or welding.

[0034] In one embodiment, the number of conductive connectors 221 can be two, such as... Figure 2The first conductive connector 221a and the second conductive connector 221b are shown. The first conductive connector 221a contacts the conductive post 121 to form an electrical connection, and the second conductive connector 221b contacts the annular conductive portion 122 to form an electrical connection. It is understood that the number of conductive connectors 221 is not limited to two, and can be set according to the number of conductive posts 121 and the actual required number of annular conductive portions 122.

[0035] In one embodiment, the number of connection terminals 222 can be two, such as... Figure 2 The terminals shown are the first connecting terminal 222a and the second connecting terminal 222b. The first connecting terminal 222a and the second connecting terminal 222b are respectively fixedly connected to the first conductive connector 221a and the second conductive connector 221b. It can be understood that the number of connecting terminals 222 is not limited to two, and can be set according to the actual number of conductive connectors 221 required.

[0036] In one embodiment, the socket housing 21 includes an upper housing 211 and a lower housing 212. The upper housing 211 and the lower housing 212 can be assembled together by interference fit, snap-fit, or other suitable means.

[0037] In one embodiment, the socket housing 21 further includes an opening 213, one end of a connecting terminal 222 is configured to pass through the opening 213 and is located on the outside of the socket housing 21, and the size of the opening 213 is the same as the cross-section of the connecting terminal 222. The socket housing 21 is made of a material with good insulating properties, one end of the connecting terminal 222 is connected to the conductive connector 221, and the other end is connected to the load. Therefore, the end of the connecting assembly 222 connected to the load is located on the outside of the housing 21, facilitating the connection of the load. Since the dustproof tail connector 100 is used in conjunction with the load, the opening 213 is not exposed to the outside during use, and the size of the opening 213 is the same as the cross-section of the connecting terminal 222, so that dust will not enter the socket housing 21 and contact the conductive component 12 through the gap between the opening 213 and the connecting assembly 222.

[0038] In one embodiment, the isolation space 17 also includes a dust-proof lubricant. The dust-proof lubricant allows the rotating body 10 to rotate flexibly within the socket housing 21 and further isolates dust, preventing dust from contacting the conductive element 12.

[0039] In one embodiment, the dust-repellent lubricant includes grease or lubricating oil. Both grease and lubricating oil have water-repellent and adhesive properties, and can act as a waterproof agent while preventing dust.

[0040] In one embodiment, a dust-repellent lubricant may be applied to the outer side of the insulating member 14 forming the isolation space 17. In another embodiment, a dust-repellent lubricant may be applied to the inner side of the socket housing 21 forming the isolation space 17.

[0041] In the dustproof rotating tail connection assembly of various embodiments of this utility model, by forming an isolation space with the insulating member and the socket housing, external dust can be effectively prevented from entering the electrode area and contacting the conductive parts, ensuring the safety and stability of the rotating tail connection assembly. At the same time, the dustproof lubricant within the isolation space further enhances the dustproof and waterproof effect of the rotating tail, ensures smooth rotation, and extends the product's service life.

[0042] The above description is merely an optional embodiment of the present utility model and is not intended to limit the embodiments of the present utility model. For those skilled in the art, the embodiments of the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the embodiments of the present utility model should be included in the protection of the embodiments of the present utility model.
