Description

[Technical Field]

[0001] This utility model relates to the field of electronic device technology, and in particular to a rotary connection device, data cable and adapter. [Background Technology]

[0002] In the existing technology, due to the inconsistent specifications of data interfaces on different electronic products, people need to configure different data cables to match different electronic products, which is extremely inconvenient when traveling. Therefore, people have developed a multi-connector rotatable data cable. The connection between the data cable and the electronic product is equipped with a rotatable connection device including multiple types of connectors to reduce the number of data cables to carry.

[0003] However, in the existing technology, the rotating connection device of the rotatable data cable is prone to misalignment of the electrical connection part after repeated rotation during use. This leads to the electrical connection parts not being aligned, affecting the electrical connection effect, the service life of the rotating connection device, and thus reducing the service life of the data cable. [Utility Model Content]

[0004] To prevent the rotary connection device from shifting during rotation and to improve its service life, this utility model provides a rotary connection device, a data cable, and an adapter.

[0005] The present invention provides a rotary connection device, comprising a first connecting component, a second connecting component, a connecting portion, and a rotating component for rotatably connecting the first connecting component, the second connecting component, and the connecting portion. The first connecting component includes a protruding ring, and the connecting portion is disposed within an accommodating space formed by the protruding ring. The connecting portion contains a plurality of metal terminals, the free ends of which protrude from the accommodating space. The second connecting component has a groove matching the protruding ring, and a conductive terminal electrically connected to the metal terminals is disposed within the groove. The rotating component passes through the first connecting component and the second connecting component, and the rotation center of the rotating component is located within the protruding ring and the groove. When the first connecting component and the second connecting component are connected, the protruding ring extends into the groove, causing the metal terminals to electrically connect with the conductive terminals.

[0006] Preferably, the first connecting component further includes a first protective shell and a first circuit board disposed within the first protective shell, and the side of the connecting portion away from the second connecting component is fixedly connected to the first circuit board; and / or the first protective shell is injection molded.

[0007] Preferably, the connecting part is rectangular or cross-shaped. When the connecting part is rectangular, the rotation center of the rotating component is located at the center of the length direction of the connecting part. When the connecting part is cross-shaped, the rotation center of the rotating component is located at the center of the cross of the connecting part; and / or the length of the connecting part is less than or equal to the diameter of the protruding ring.

[0008] Preferably, the first protective shell extends in a direction away from the first circuit board to form the raised ring, and the raised ring has a clearance opening corresponding to the short side of the connecting portion.

[0009] Preferably, the first protective shell further includes a fixing part connected to the protruding ring, the diameter of the fixing part being larger than the diameter of the protruding ring, the first circuit board being located within the accommodating space enclosed by the protruding ring, and the first circuit board being disposed within the fixing part.

[0010] Preferably, the metal terminal is a spring-loaded contact pin, the conductive terminal is a conductive ring, and / or the number of the metal terminals is at least five.

[0011] Preferably, the second connecting assembly includes a second protective shell, the second protective shell having a channel for the protruding ring to enter, the diameter of the channel being smaller than the diameter of the fixing part.

[0012] Preferably, the rotary connection device further includes an external fixing member disposed on the side of the first connecting component away from the second connecting component. The external fixing member includes a first fixing end and a second fixing end. The rotating component passes through the first protective shell and is connected to the first fixing end. The second fixing end is connected to the second protective shell. During the relative rotation of the first connecting component and the second connecting component, the second fixing end can abut against the first protective shell.

[0013] To solve the technical problem, this utility model also provides a data cable, including a cable body and the aforementioned rotary connecting device connected to at least one end of the cable body, wherein the first connecting component is connected to the cable body, and the second connecting component further includes at least two different types of connecting ports.

[0014] To solve the technical problem, this utility model also provides an adapter, including the above-mentioned rotating connection device and interface end. The interface end is located at the end of the first connection component away from the second connection component, and the second connection component also includes at least two connection ports of different types.

[0015] Compared with the prior art, the rotary connection device, data cable and adapter of this utility model have the following advantages:

[0016] 1. When the first connecting component and the second connecting component of this utility model are connected, the protruding ring extends into the groove to electrically connect the metal terminal and the conductive terminal. It can be understood that, due to the cooperation between the protruding ring and the groove, the protruding ring remains within the groove during the mutual rotation of the first and second connecting components. This ensures that the metal terminal within the protruding ring and the conductive terminal within the groove remain aligned, preventing misalignment of the metal terminal and conductive terminal after repeated rotation and wear of the first and second connecting components, thus improving the service life of the rotary connecting device. Simultaneously, this utility model also protects the metal terminal through the connecting part. During the mutual rotation of the first and second connecting components, no lateral load is applied to the metal terminal. Furthermore, the protection provided by the connecting part reduces the impact of friction and corrosive substances in the working environment on the metal terminal during operation, greatly improving the service life of the metal terminal and further extending the service life of the rotary connecting device.

[0017] 2. The connecting part of this utility model is fixedly connected to the first circuit board. During the mutual rotation of the first connecting component and the second connecting component, the connecting part will not shift in position, which is beneficial to keep the metal terminal and the conductive terminal aligned at all times.

[0018] 3. The length of the connecting part of this utility model is less than or equal to the diameter of the protruding ring, so that the connecting part is located inside the protruding ring, so that the connecting part will not affect the mutual rotation between the first connecting component and the second connecting component, which is beneficial to improving the sensitivity of rotation.

[0019] 4. The protruding ring of this utility model has a clearance opening at the short side of the connecting part. The clearance opening allows the short side of the connecting part to enter the clearance opening, which is beneficial to the miniaturization of the rotary connecting device and avoids the rotary connecting device being too large due to the thickness of the protruding ring.

[0020] 5. The first circuit board of this utility model is located inside the fixing part. The diameter of the fixing part is larger than the diameter of the protruding ring. By setting the larger circuit board inside the fixing part and the smaller connecting part inside the protruding ring, the space is reasonably arranged, which is conducive to the miniaturization of the rotating connecting device.

[0021] 6. The present invention has at least 5 metal terminals, which can achieve a transmission power of at least 60W and a fast transmission speed.

[0022] 7. The diameter of the channel in this utility model is smaller than the diameter of the fixing part. When the first connecting component is connected to the second connecting component, the fixing part with a larger diameter will overlap the second protective shell and cover the small diameter channel opening. This helps to prevent dust and other substances from entering the groove and causing adverse effects on the metal terminals and conductive terminals.

[0023] 8. The external fastener of this utility model can further enhance the stability of the connection between the first connecting component and the second connecting component, and at the same time limit the rotation angle between the first connecting component and the second connecting component, so as to avoid the user rotating too frequently, thereby improving the service life of the rotary connection device.

[0024] 9. This utility model also provides a data cable and adapter, including the aforementioned rotary connecting device. In producing the rotary connecting device for the data cable and adapter, the components on the first circuit board and the second circuit board are first assembled. For example, in some specific embodiments, metal terminals are fixed to the first circuit board, and the connecting part is welded and fixed to the first circuit board. Then, the first circuit board and the second circuit board are placed in different molds. A first protective shell is set on the outside of the first circuit board using injection molding, and an inner protective shell and a second protective shell are sequentially set on the outside of the second circuit board. This yields the first connecting component and the second connecting component of the rotary connecting device. The rotary connecting device is then obtained by rotating the first connecting component and the second connecting component together. It is understood that the first connecting component and the second connecting component can be manufactured simultaneously using two production lines, simplifying and facilitating the production process and greatly improving production efficiency. Furthermore, since the rotary connecting device of this utility model can maintain a stable electrical connection during rotation, it is less prone to damage during repeated rotations, thus significantly extending the service life of the data cable and adapter.

[0048] Please combine Figure 1 and Figure 2 The first embodiment of this utility model provides a rotary connecting device 1, including a first connecting component 11, a second connecting component 12, a connecting part 15, and a rotating component 14 for rotatably connecting the first connecting component 11 and the second connecting component 12.

[0049] Combination Figures 1 to 3The first connecting component 11 includes a protruding ring 18, and a connecting portion 15 is disposed within the accommodating space 110 formed by the protruding ring 18. The connecting portion 15 contains a plurality of metal terminals 16, with the free ends 161 of the metal terminals 16 protruding out of the accommodating space 110. The second connecting component 12 has a groove 19 that matches the protruding ring 18. The groove 19 contains conductive terminals 17 that are electrically connected to the metal terminals 16. A rotating component 14 passes through the first connecting component 11 and the second connecting component 12, and the rotation center of the rotating component 14 is located within the protruding ring 18 and the groove 19. When the first connecting component 11 and the second connecting component 12 are connected, the protruding ring 18 extends into the groove 19, causing the metal terminals 16 to be electrically connected to the conductive terminals 17.

[0050] It is understandable that, due to the cooperation between the protruding ring 18 and the groove 19, the sidewalls around the groove 19 will restrict the protruding ring 18 within the groove 19. During the mutual rotation of the first connecting component 11 and the second connecting component 12, the protruding ring 18 is always kept within the groove 19, thereby ensuring that the metal terminal 16 within the protruding ring 18 always rotates within the groove 19. This ensures that the metal terminal 16 within the protruding ring 18 and the conductive terminal 17 within the groove 19 are always aligned, preventing the metal terminal 16 and the conductive terminal 17 from becoming misaligned after repeated rotation and wear of the first connecting component 11 and the second connecting component 12. This is beneficial for improving the service life of the rotary connecting device 1.

[0051] In some specific embodiments of this utility model, the metal terminal 16 may include a spring contact pin, and the conductive terminal 17 may include a conductive ring. In other embodiments of this utility model, the metal terminal 16 may also be a metal spring or the like, and its exposed free end 161 of the connecting portion 15 is generally U-shaped.

[0052] Continue to combine Figures 1 to 3 The first connecting assembly 11 further includes a first protective shell 111 and a first circuit board 112 disposed within the first protective shell 111. A connecting portion 15 is disposed within the first protective shell 111, and the side of the connecting portion 15 away from the second connecting assembly 12 is fixedly connected to the first circuit board 112. Through the fixed connection between the connecting portion 15 and the first circuit board 112, the connecting portion 15 will not shift position during the relative rotation of the first connecting assembly 11 and the second connecting assembly 12, which helps to keep the metal terminal 16 and the conductive terminal 17 aligned at all times.

[0053] Specifically, the first protective shell 111 is prepared by injection molding, which has high production efficiency. In some embodiments, the protruding ring 18 is integrally formed with the first protective shell 111.

[0054] Furthermore, the connecting portion 15 is roughly rectangular, that is, generally rectangular in shape, the protruding ring 18 is circular or elliptical in shape, and the shape of the groove 19 corresponds to the shape of the protruding ring 18. In some embodiments, the connecting portion 15 may also be cross-shaped.

[0055] It is understandable that setting the protruding ring 18 and the groove 19 to be circular or elliptical facilitates better mutual rotation between the first connecting component 11 and the second connecting component 12. Setting the connecting portion 15 to a near-rectangular shape facilitates the arrangement of the metal terminals 16 within the connecting portion 15.

[0056] Continue to combine Figures 1 to 3 The second connecting assembly 12 includes a second protective shell 121, a second circuit board 122 disposed within the second protective shell 121, and an inner protective shell 123. The second circuit board 122 is disposed within the inner protective shell 123. The inner protective shell 123 extends toward the first connecting assembly 11 to form a groove 19. A conductive terminal 17 is disposed at the bottom of the groove 19 and electrically connected to the second circuit board 122.

[0057] Continue to combine Figures 1 to 3 The rotating connection device 1 also includes an outer fixing member 13 disposed on the side of the first connecting component 11 away from the second connecting component 12. The outer fixing member 13 includes a first fixing end 131 and a second fixing end 132. The rotating component 14 passes through the first protective shell 111 and is connected to the first fixing end 131. The second fixing end 132 is connected to the second protective shell 121. During the relative rotation of the first connecting component 11 and the second connecting component 12, the second fixing end 132 can abut against the first protective shell 111.

[0058] Specifically, the external fixing member 13 of this utility model includes two second fixing ends 132, which are respectively connected to the two ends in the length direction of one side of the second protective shell 121, so that the rotation range of the first connecting component 11 and the second connecting component 12 is less than 360°.

[0059] It is understandable that during the relative rotation of the first connecting component 11 and the second connecting component 12, when one of the two second fixed ends 132 abuts against the first protective shell 111, the first connecting component 11 and the second connecting component 12 reach their rotation limit and cannot continue to rotate in that direction. By limiting the rotation angle, excessively frequent rotation by the user can be avoided, thereby improving the service life of the rotary connecting device 1.

[0060] Furthermore, the connecting part 15 includes a bottom 151 fixed to the first circuit board 112. The bottom 151 and the first circuit board 112 can be fixedly connected by welding or other means. The connecting part 15 is also provided with independent through holes 150 corresponding to the number of metal terminals 16. Each through hole 150 allows one metal terminal 16 to pass through, and the free end 161 of the metal terminal 16 is exposed in the through hole 150.

[0061] It is understood that by protecting each metal terminal 16 through the independent through hole 150 on the connecting part 15, the first connecting component 11 and the second connecting component 12 will not cause lateral load on the metal terminal 16 during mutual rotation. At the same time, the protection of the connecting part 15 also helps to reduce the impact of friction and corrosive substances in the working environment on the metal terminal 16 during operation, which greatly improves the service life of the metal terminal 16 and further improves the service life of the rotary connecting device 1.

[0062] Combination Figure 2 and Figure 5 The rotating assembly 14 includes a rotating shaft 142 and a protective sleeve 141 sleeved on the rotating shaft 142. The protective sleeve 141 is located on the side of the second circuit board 122 away from the first connecting assembly 11 and is used to fix the rotating shaft 142 to improve the stability of rotation. The protective sleeve 141 can be made of materials such as plastic.

[0063] Furthermore, the connecting part 15 is also provided with a shaft hole 152 for the shaft 142 to pass through, and the shaft 142 can pass through the shaft hole 152 to connect with the first connecting component 11 and the second connecting component 12 respectively.

[0064] Combination Figure 3 , Figure 5 and Figure 6 In this embodiment, the connecting portion 15 extends out of the accommodating space 110 formed by the protruding ring 18, which facilitates better electrical connection between the metal terminal 16 in the connecting portion 15 and the conductive terminal 17 in the groove 19.

[0065] It is understood that in other embodiments, the connecting portion 15 may also be located within the accommodating space 110. When the connecting portion 15 is located within the accommodating space 110, the metal terminal 16 within the connecting portion 15 will extend out of the accommodating space 110 so that the metal terminal 16 extends out of the protruding ring 18 and connects with the conductive terminal 17 in the groove 19.

[0066] Combination Figure 2 and Figure 6 The metal terminal 16 of this invention is elastic. In a free state (i.e., when the metal terminal 16 is not under pressure and is not in contact with the conductive terminal 17), the distance between the metal terminal 16 exposed in the connection part 15 is D1, which is 1mm-3mm. When the protruding ring 18 extends into the groove 19, the free end 161 of the metal terminal 16 protruding from the accommodating space 110 can contact the conductive terminal 17 to achieve electrical connection.

[0067] It is understandable that when the user rotates the first connecting component 11 and the second connecting component 12, force may be applied to various positions of the first connecting component 11 and the second connecting component 12. If the force is too great, the metal terminal 16 in the rotating connecting device 1 may be subjected to excessive force and fail to spring back. However, this utility model protects the metal terminal 16 through the connecting part 15. The connecting part 15 will bear most of the force, thereby preventing the metal terminal 16 from being excessively compressed or subjected to lateral load. This can avoid the problem of the metal terminal 16 getting stuck or not springing back, and improve the service life of the rotating connecting device 1.

[0068] Combination Figure 2 and Figure 7 Furthermore, in order to improve the smoothness of the mutual rotation between the first connecting component 11 and the second connecting component 12, the length D3 of the connecting part 15 is less than or equal to the diameter D2 of the protruding ring 18, so that the connecting part 15 is located inside the protruding ring 18, and the connecting part 15 protruding out of the protruding ring 18 is avoided from affecting the mutual rotation between the first connecting component 11 and the second connecting component 12.

[0069] It can be understood that when the connecting part 15 is a rectangle, the length D3 of the connecting part 15 refers to the length of the long side of the connecting part 15. The rotation center of the rotating assembly 14 is set at the center of the long side of the connecting part 15, such as... Figure 7 As shown.

[0070] In some embodiments, the connecting portion 15 is cross-shaped. When the connecting portion 15 is cross-shaped, the length D3 of the connecting portion 15 refers to the length of the longest two ends of the cross shape. The rotation center of the rotating assembly 14 is located at the center of the cross shape of the connecting portion 15. Figure 8 As shown.

[0071] Continue to combine Figure 2 and Figure 7 To make efficient use of space, the first protective shell 111 also includes a fixing part 113 connected to the protruding ring 18. The diameter D4 of the fixing part 113 is larger than the diameter D2 of the protruding ring 18. The first circuit board 112 is located within the accommodating space 110 formed by the protruding ring 18, and the first circuit board 112 is disposed within the fixing part 113. By placing the larger first circuit board 112 within the larger fixing part 113 and the smaller connecting part 15 within the smaller protruding ring 18, the space is rationally arranged, which further facilitates the miniaturization of the rotary connecting device 1.

[0072] Continue to combine Figure 2 and Figure 7To make efficient use of the internal space of the rotary connecting device 1 and to make the rotary connecting device 1 more compact, the first protective shell 111 extends away from the first circuit board 112 to form a raised ring 18. The raised ring 18 has a clearance opening 180 at the short side of the connecting portion 15. The clearance opening 180 allows the short side of the connecting portion 15 to enter the clearance opening 180, avoiding the space occupied by the thickness of the raised ring 18. This allows the raised ring 18 to be as small as possible while maintaining a sufficiently large connecting portion 15, saving space and materials. Furthermore, with a sufficiently large connecting portion 15, more metal terminals 16 can be arranged within the connecting portion 15.

[0073] Furthermore, combined Figure 3 and Figure 7 The second protective shell 121 is provided with a channel 120 for the protruding ring 18 to enter. The diameter D5 of the channel 120 is smaller than the diameter D4 of the fixing part 113. It can be understood that when the diameter of the channel 120 is smaller than the diameter of the fixing part 113, after the first connecting assembly 11 and the second connecting assembly 12 are connected, the fixing part 113 will overlap the second protective shell 121 to cover the channel 120, which helps to prevent dust and other substances from entering the groove 19 and causing adverse effects on the metal terminal 16 and the conductive terminal 17.

[0074] Furthermore, the metal terminals 16 of this utility model include at least five, and the metal terminals 16 are respectively disposed on both sides of the rotating assembly 14. The rotating assembly 14 is approximately located at the center of the connecting part 15. The metal terminals 16 include signal V (Voltage Bus), D+, D- (Data+, Data-, differential data line pairs), CC (Configuration Channel), and G (Ground, ground).

[0075] Combination Figure 9 In some embodiments, the number of metal terminals 16 is five, arranged in a roughly straight line on both sides of the rotating assembly 14, from left to right ( Figure 9 The metal terminals 16 (in the direction indicated by the middle arrow f 1) are G, D-, CC, D+, and V, respectively.

[0076] Combination Figure 10 In some embodiments, the number of metal terminals 16 is seven, respectively disposed on both sides of the rotating assembly 14. From left to right ( Figure 10 As indicated by the middle arrow (f 1 direction), each metal terminal 16 is G, D-, CC, D+, and V, with two V signals on the far left and two G signals on the far right.

[0077] Combination Figure 11In some embodiments, the number of metal terminals 16 is nine, respectively arranged around the periphery of the rotating assembly 14, from left to right ( Figure 11 As indicated by the middle arrow (f 1 direction), each metal terminal 16 is designated as G, D-, CC, D+, and V, with two V signals on the far left and two G signals on the far right; from top to bottom ( Figure 11 One of the two metal terminals 16 (in the direction of f 2 as indicated by the middle arrow) is G, and the other is V.

[0078] It is understood that in other embodiments, the metal terminals 16 may be arranged in other quantities on both sides of the rotating assembly, such as 10, 11, 13, etc.

[0079] It is understandable that increasing the number of metal terminals 16 can achieve the function of conductive current diversion, that is, the total current is distributed to multiple metal terminals 16 for transmission, which can achieve better current transmission, prevent power outages and overheating during use, and can stably achieve high power output, such as 240W, making it more convenient for users.

[0080] Combination Figure 12 The second embodiment of this utility model provides a data cable 2, including a cable body 21 and a rotary connecting device 1 provided in the first embodiment of this utility model, which is connected to at least one end of the cable body 21. The first connecting component 11 is connected to the cable body 21, and the second connecting component 12 also includes at least two different types of connecting ports 22.

[0081] Specifically, in this invention, the second connecting component 12 includes two different types of connection ports 22, respectively located at both ends of the second connecting component 12. In other embodiments, three, four, five, or six different types of connection ports may be provided around the second connecting component 12 to accommodate more different types of electronic devices.

[0082] Furthermore, at least one connector 22 can be any of the following interface types: USB Type-A, USB Type-B, USB Type-C, MicroUSB, MiniUSB, Lightning, Mag Safe (magnetic connector), DC round connector, etc.

[0083] Specifically, in this utility model, each end of the cable 21 is connected to a rotating connection device 1 provided in the first embodiment of this utility model. In other embodiments, one end of the cable 21 may be connected to the rotating connection device 1 provided in the first embodiment of this utility model, and the other end may be connected to other existing connection structures, such as a single interface type such as USB Type-A, USB Type-B, USB Type-C, Micro USB, MiniUSB, Lightning, MagS afe (magnetic interface), DC round head, etc.

[0084] It is understood that the data cable 2 provided in the second embodiment of this utility model has the same beneficial effects as the rotary connection device 1 provided in the first embodiment of this utility model, and will not be described in detail here.

[0091] This utility model provides a data cable and adapter, including the aforementioned rotary connecting device. In manufacturing the rotary connecting device for the data cable and adapter, the components on the first and second circuit boards are first assembled. For example, in some specific embodiments, metal terminals are fixed to the first circuit board, and the connecting part is welded to the first circuit board. Then, the first and second circuit boards are placed in different molds. A first protective shell is formed on the outside of the first circuit board using injection molding, and an inner protective shell and a second protective shell are formed sequentially on the outside of the second circuit board. This yields the first connecting component and the second connecting component of the rotary connecting device. The rotary connecting device is then obtained by rotating the first connecting component and the second connecting component together. It is understood that the first and second connecting components can be manufactured simultaneously using two production lines, simplifying and facilitating the production process and greatly improving production efficiency. Furthermore, because the rotary connecting device of this utility model maintains a stable electrical connection during rotation, it is less prone to damage during repeated rotations, significantly extending the service life of the data cable and adapter.
