Detailed Implementation

[0018] The technical solutions of this disclosure will be further described in detail below with reference to the accompanying drawings and some embodiments.

[0019] In the embodiments described in this disclosure, it should be noted that, unless otherwise stated and limited, the term "connection" should be interpreted broadly. For example, it can refer to an electrical connection or a connection between two internal components. It can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above term according to the specific circumstances.

[0020] It should be noted that the terms "first," "second," and "third" used in the embodiments of this disclosure are merely used to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first," "second," and "third" can be interchanged in a specific order or sequence where permitted. It should be understood that the objects distinguished by "first," "second," and "third" can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein.

[0021] The following combination Figures 1 to 8 The conductive device described in the embodiments of this disclosure will be described in detail.

[0022] like Figure 1 and Figure 4 As shown in the embodiments of this disclosure, the conductive device may include: a first support member 310, a first conductive member 100, a second support member 320, and a second conductive member 200. The first conductive member 100 may be disposed on the first support member 310 by means of bonding, snap-fitting, welding, etc.; the first conductive member 100 may include a first annular side surface 110 and a second annular side surface 120 disposed opposite to each other; an annular groove 130 is defined between the first annular side surface 110 and the second annular side surface 120; the second support member 320 is rotatably disposed on the first support member 310; the second conductive member 200 may be disposed on the second support member 320 by means of bonding, snap-fitting, welding, etc.; the second conductive member 200 may include a first protrusion 210 inserted into the annular groove 130, the first protrusion 210 contacting the first annular side surface 110 and the second annular side surface 120 respectively.

[0023] The inventors discovered that data cable structures include conductive structures, which have poor conductivity stability. For example, the two structural components of a conductive structure are typically connected through only one set of surface contacts, and after a period of use, the two structural components often separate, resulting in poor conductivity stability. In contrast, the conductive device of this application has a first protrusion 210 that contacts the first annular side surface 110 and the second annular side surface 120 respectively. This two sets of surface contacts achieve electrical connection between the first conductive element 100 and the second conductive element 200, significantly improving the conductivity stability of the device. Furthermore, achieving electrical connection between the first conductive element 100 and the second conductive element 200 through two sets of surface contacts also increases the conductive contact area between them, thereby reducing conductive contact impedance and shrinkage resistance, and improving the conductivity between the first conductive element 100 and the second conductive element 200.

[0024] In the embodiments of this disclosure, the conductive device can be used in data cable devices, charging devices, electronic devices, etc., for power supply, charging, data transmission, etc. This disclosure does not limit this use.

[0025] In this embodiment, the structure of the first support member 310 is not limited. The first support member 310 is a non-conductive structure. For example, the material of the first support member 310 can be a non-conductive polymer material, resin, etc. As an example, the first support member 310 can be the substrate material of a circuit board.

[0026] The shape of the first support member 310 is not limited. For example, the first support member 310 can be a disc-shaped structure or a ring-shaped structure, etc.

[0027] In this embodiment, the structure of the first conductive element 100 is not limited. For example, the material of the first conductive element 100 can be conductive materials such as copper, copper alloy, silver, silver-graphite, and silver-nickel.

[0028] The first conductive element 100 may consist only of a first annular side surface 110 and a second annular side surface 120 disposed opposite to each other; an annular groove 130 is defined between the first annular side surface 110 and the second annular side surface 120; here, the first annular side surface 110 and the second annular side surface 120 can be directly connected, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown. Of course, the first conductive element 100 may also include a first bottom surface 140 connected to the first annular side surface 110 and the second annular side surface 120 respectively, as shown. Figure 7 and Figure 8 As shown.

[0029] The annular groove 130 can form a depth direction between the groove opening and the groove bottom. The first protrusion 210 can be inserted into the annular groove 130 from the groove opening. The first protrusion 210 and the groove bottom of the annular groove 130 can be spaced apart. The groove bottom of the annular groove 130 can be formed by the first bottom surface 140, or by the portion where the first annular side surface 110 and the second annular side surface 120 are connected.

[0030] In some examples, the direction of the rotation axis of the second support member 320 relative to the first support member 310 and the depth direction of the annular groove 130 may be the same or substantially the same.

[0031] The depth directions of the first annular side surface 110 and the annular groove 130 can be parallel or non-parallel. For example Figure 6As shown, when the first annular side surface 110 is arranged parallel to the depth direction of the annular groove 130, the first annular side surface 110 can be arranged along the depth direction of the annular groove 130. For example, the depth direction of the annular groove 130 can be vertical, and the first annular side surface 110 can be arranged along the vertical direction; here, the first annular side surface 110 can be a cylindrical surface. When the first annular side surface 110 is not parallel to the depth direction of the annular groove 130, the first annular side surface 110 may not be arranged along the depth direction of the annular groove 130. Figure 3 , Figure 5 and Figure 7 As shown, the first annular side surface 110 can be inclined. For example, the depth direction of the annular groove 130 can be vertical, and the first annular side surface 110 can be arranged in a non-vertical direction. Here, the first annular side surface 110 can be a frustoconical surface.

[0032] The depth directions of the second annular side 120 and the annular groove 130 can be set parallel or non-parallel. For example Figure 5 and Figure 8 As shown, when the second annular side surface 120 is arranged parallel to the depth direction of the annular groove 130, the second annular side surface 120 can be arranged along the depth direction of the annular groove 130. For example, the depth direction of the annular groove 130 can be vertical, and the second annular side surface 120 can be arranged along the vertical direction; here, the second annular side surface 120 can be a cylindrical surface. When the second annular side surface 120 is not parallel to the depth direction of the annular groove 130, the second annular side surface 120 may not be arranged along the depth direction of the annular groove 130. Figure 3 , Figure 6 and Figure 7 As shown, the second annular side surface 120 can be inclined. For example, the depth direction of the annular groove 130 can be vertical, and the second annular side surface 120 can be arranged in a non-vertical direction. Here, the second annular side surface 120 can be a frustoconical surface.

[0033] The second annular side 120 and the first annular side 110 can be arranged in parallel or not in parallel.

[0034] The number of annular grooves 130 is not limited. For example, the first conductive member 100 may include at least two spaced-apart annular grooves 130, and the number of second conductive members 200 may be at least two. These at least two second conductive members 200 may be spaced-apart, and the first protrusions 210 of the at least two second conductive members 200 may be respectively inserted into the at least two annular grooves 130, so that each first protrusion 210 and the corresponding annular groove 130 are electrically connected. Here, the at least two spaced-apart annular grooves 130 may be coaxially arranged. As an example, such as... Figure 1As shown, the first conductive element 100 may include five annular grooves 130 spaced apart, and the number of second conductive elements 200 may be five, with the first protrusions 210 of the five second conductive elements 200 respectively inserted into the five annular grooves 130.

[0035] In this embodiment, the structure of the second support member 320 is not limited. The second support member 320 can be a non-conductive structure. For example, the material of the second support member 320 can be a non-conductive polymer material, resin, etc. As an example, the second support member 320 can be the substrate material of a circuit board.

[0036] The shape of the second support member 320 is not limited. For example, the second support member 320 can be a disc-shaped structure or a ring-shaped structure, etc. This disclosure does not limit it in this regard.

[0037] The method by which the second support member 320 and the first support member 310 are rotatably configured is not limited. For example, the second support member 320 and the first support member 310 can be rotatably configured using a pivot structure, a protruding column structure, or the like. Alternatively, the second support member 320 and the first support member 310 can also be rotatably configured by being mounted on two structures capable of relative rotation.

[0038] Here, the rotation axis of the second support member 320 and the axis of the annular groove 130 can be the same or substantially the same; thus, the first protrusion 210 can be inserted into the annular groove 130 while the second support member 320 and the first support member 310 are rotating relative to each other.

[0039] In this embodiment, the structure of the second conductive element 200 is not limited. For example, the material of the second conductive element 200 can be conductive materials such as copper, copper alloy, silver, silver-graphite, and silver-nickel.

[0040] The shape of the second conductive element 200 is not limited. For example, the second conductive element 200 may be in the form of a strip to reduce the installation space and volume of the second conductive element 200. As an example, the second conductive element 200 may be in the form of a column. The cross-sectional shape of the second conductive element 200 is not limited. For example, the cross-sectional shape of the second conductive element 200 may be circular, elliptical, trapezoidal, etc.

[0041] The number of second conductive elements 200 is not limited. For example, the number of second conductive elements 200 can be at least two, and the at least two second conductive elements 200 can be spaced apart in the circumferential direction of the annular groove 130. Here, at least two second conductive elements 200 are electrically connected to one annular groove 130, which can greatly improve the safety and stability of the electrical connection between the at least two second conductive elements 200 and the annular groove 130. For example, if one of the at least two second conductive elements 200 is damaged, the other two second conductive elements 200 can still be electrically connected to the annular groove 130. As an example, such as Figure 1 and Figure 4 As shown, the number of second conductive elements 200 can be three, and the three second conductive elements 200 are arranged circumferentially in the annular groove 130; the three second conductive elements 200 are electrically connected to one annular groove 130.

[0042] The cross-sectional dimensions of the second conductive element 200 in each region can be the same or different.

[0043] The shape of the first protrusion 210 is not limited. For example Figure 1 As shown, the first protrusion 210 can be curved, which increases the contact area between the first protrusion 210 and the first annular side surface 110 and the second annular side surface 120. Of course, the first protrusion 210 can also be non-curved. For example, the first protrusion 210 can also be straight.

[0044] The cross-sectional shape of the first protrusion 210 is not limited. For example, the cross-sectional shape of the first protrusion 210 can be circular, elliptical, etc. As an example, the cross-section of the first protrusion 210 can be circular to make the first protrusion 210 slide more smoothly in the annular groove 130. As another example, the cross-section of the first protrusion 210 can be elliptical to make the first protrusion 210 slide more smoothly in the annular groove 130.

[0045] As an example, the second conductive member 200 may be elastic, and the first protrusion 210 may have a first pressure toward the first annular side 110 and a second pressure toward the second annular side 120. The first pressure on the first protrusion 210 toward the first annular side 110 improves the stability and contact area of ​​the contact between the first protrusion 210 and the first annular side 110. Similarly, the second pressure on the first protrusion 210 toward the second annular side 120 improves the stability and contact area of ​​the contact between the first protrusion 210 and the second annular side 120. The elasticity of the second conductive member 200 prevents the first protrusion 210 from getting stuck during sliding within the annular groove 130. In the event of jamming between the first protrusion 210 and the annular groove 130, deformation of the second conductive member 200 allows the first protrusion 210 to continue sliding relative to the annular groove 130. Meanwhile, the second conductive element 200 is elastic and can set a larger pressure between the first protrusion 210 and the annular groove 130, so as to further improve the stability and contact area of ​​the first protrusion 210 and the annular groove 130.

[0046] Here, the value of the first pressure can be greater than zero, and the value of the second pressure can be greater than zero, thereby preventing the first protrusion 210 from separating from the annular groove 130, and improving the stability and contact area of ​​the conductive contact between the first protrusion 210 and the annular groove 130.

[0047] Here, the first pressure and the second pressure can satisfy the same conditions or they can be different. Same conditions mean identical or substantially identical. When the first pressure and the second pressure satisfy the same conditions, the first frictional force between the first protrusion 210 and the first annular side surface 110 and the second frictional force between the first protrusion 210 and the second annular side surface 120 can be the same or substantially the same. This allows the first protrusion 210 to slide more smoothly within the annular groove 130, improving the smoothness of the sliding within the annular groove 130 and reducing the risk of the first protrusion 210 getting stuck within the annular groove 130.

[0048] In some implementations of the embodiments of this disclosure, the distance between the first annular side 110 and the second annular side 120 can gradually decrease from the opening of the annular groove 130 to the bottom of the annular groove 130; thereby forming an flared structure in the annular groove 130, which facilitates the insertion of the first protrusion 210 into the annular groove 130 and allows the first protrusion 210 to have a tendency to slide towards the bottom of the annular groove 130, thereby improving the stability and contact area of ​​the first protrusion 210 with the first annular side 110 and the second annular side 120 respectively.

[0049] Of course, in its implementation, the distance between the first annular side 110 and the second annular side 120 from the opening of the annular groove 130 to the bottom of the annular groove 130 can remain unchanged. Alternatively, the distance between the first annular side 110 and the second annular side 120 can be increased first and then decreased. This disclosure does not limit this.

[0050] In this implementation, the first annular side 110 and the second annular side 120 are not arranged in parallel.

[0051] In this implementation, at least one of the first annular side surface 110 and the second annular side surface 120 can be non-parallel to the depth direction of the annular groove 130. For example, one of the first annular side surface 110 and the second annular side surface 120 can be parallel to the depth direction of the annular groove 130, and the other of the first annular side surface 110 and the second annular side surface 120 can be inclined, such as... Figure 5 , Figure 6 and Figure 8 As shown. For example, such as... Figure 3 and Figure 7 As shown, the first annular side 110 and the second annular side 120 can also be inclined. The inclined arrangement of the first annular side 110 and the second annular side 120 can reduce the difference between the first frictional force between the first protrusion 210 and the first annular side 110 and the second frictional force between the first protrusion 210 and the second annular side 120, thereby improving the smoothness and stability of the first protrusion 210 sliding in the annular groove 130.

[0052] In this implementation, the first protrusion 210 and the bottom of the annular groove 130 can be spaced apart. The spaced arrangement of the first protrusion 210 and the bottom of the annular groove 130, and the gradual decrease in distance between the first annular side surface 110 and the second annular side surface 120 from the opening of the annular groove 130 to the bottom of the annular groove 130, enable the first protrusion 210 to tend to move towards the bottom side of the narrower part of the annular groove 130, thereby enabling the first protrusion 210 to contact the first annular side surface 110 and the second annular side surface 120 more closely, respectively. For example, if the first protrusion 210 slides within the annular groove 130 for a long time, the size of the first protrusion 210 may decrease due to wear. Here, since the distance between the first annular side 110 and the second annular side 120 gradually decreases from the opening of the annular groove 130 to the bottom of the annular groove 130, the first protrusion 210 is spaced apart from the bottom of the annular groove 130, and the first protrusion 210 can slide towards the bottom of the annular groove 130, thereby enabling the first protrusion 210 to stably re-contact different areas of the first annular side 110 and the second annular side 120 respectively.

[0053] In this implementation, a first included angle A can be formed between the first annular side surface 110 and the second annular side surface 120; the value of the first included angle A is not limited. For example, the value of the first included angle A can be 80 degrees to 100 degrees, 70 degrees to 170 degrees, 80 degrees to 150 degrees, 90 degrees to 120 degrees, etc. For another example, the value of the first included angle A can be 90 degrees, 85 degrees, 87 degrees, 89 degrees, 92 degrees, 95 degrees, etc. When the value of the first included angle A is 90 degrees or close to 90 degrees, the stability of the contact between the first protrusion 210 and the first annular side surface 110 and the second annular side surface 120, and the contact area, can be improved.

[0054] In this implementation, the first conductive element 100 may further include a first bottom surface 140 connected to the first annular side surface 110 and the second annular side surface 120 respectively, and the first protrusion 210 and the first bottom surface 140 may be spaced apart; here, the first annular side surface 110, the second annular side surface 120 and the first bottom surface 140 surround and form an annular groove 130 with a trapezoidal cross-section, such as Figure 7 and Figure 8 As shown.

[0055] Of course, the first annular side 110 and the second annular side 120 can also be directly connected, and the connecting portion of the first annular side 110 and the second annular side 120 can be spaced apart from the first protrusion 210. Here, the cross-section of the annular groove 130 can be triangular, such as... Figure 3 , Figure 5 and Figure 6 As shown.

[0056] In some implementations of the embodiments of this disclosure, the first protrusion 210 may include a first arcuate surface and a second arcuate surface disposed opposite to each other; the first arcuate surface contacts the first annular side surface 110; the second arcuate surface contacts the second annular side surface 120; the first protrusion 210 can improve the smoothness of sliding within the annular groove 130 by means of the arcuate surface and the annular side surface of the annular groove 130, and prevent the first protrusion 210 from getting stuck within the annular groove 130.

[0057] Of course, in other implementations, the first protrusion 210 may also contact the first annular side surface 110 via a curved surface, a flat surface, or the like. The first protrusion 210 may also contact the second annular side surface 120 via a curved surface, a flat surface, or the like.

[0058] In this implementation, the first annular side 110 and the second annular side 120 can be symmetrically arranged; the first arcuate surface and the second arcuate surface can also be symmetrically arranged. By symmetrically arranging the first annular side 110 and the second annular side 120, as well as the first arcuate surface and the second arcuate surface, the first frictional force between the first arcuate surface and the first annular side 110 and the second frictional force between the second arcuate surface and the second annular side 120 can be the same or substantially the same. This can improve the smoothness of the sliding of the first protrusion 210 in the annular groove 130, and improve the stability of the contact between the first protrusion 210 and the first annular side 110 and the second annular side 120, respectively.

[0059] In some implementations of the embodiments of this disclosure, such as Figure 4 As shown, the conductive device may further include: a base 330. The base 330 may be attached to the second support member 320 by means of bonding, snap-fitting, welding, etc.; the base 330 may have a first groove 331 corresponding to the position of the annular sliding groove 130; the second conductive member 200 is disposed on the base 330, and the first protrusion 210 protrudes from the side wall of the first groove 331 from the base 330. The first groove 331 can provide a limiting space for the deformation of the second conductive member 200. In other words, the second conductive member 200 deforms within the space defined by the first groove 331, thereby preventing the second conductive member 200 from deforming into other spaces due to sliding resistance and failing to return to its original position.

[0060] In this implementation, the structure of the base 330 is not limited. The base 330 is a non-conductive structure. For example, the material of the base 330 can be a non-conductive polymer material, plastic, etc.

[0061] The shape of the base 330 is not limited. For example, the second support member 320 can be a block structure, a plate structure, etc.

[0062] The shape of the first groove 331 is not limited. The first groove 331 can match the shape of the second conductive element 200. For example, the second conductive element 200 can be strip-shaped, and the first groove 331 can be strip-shaped. During the sliding of the first protrusion 210 in the annular groove 130, the strip-shaped second conductive element 200 can deform within the strip-shaped first groove 331. By limiting the second conductive element 200 through the sidewall of the first groove 331, the second conductive element 200 can be prevented from deforming to areas outside the first groove 331.

[0063] This disclosure also describes a data cable device, including a conductive device, a housing, an interface component, a winding component, and a cable. The housing may have a receiving cavity and an opening communicating with the receiving cavity; the interface component may be fixed to the housing by means of bonding, snapping, welding, etc.; the winding component may be rotatably disposed in the receiving cavity by means of a rotating shaft structure; the cable may include: a winding segment, a first end, and a second end. The winding segment may be used to wind around the winding component; the first end is connected to the winding segment and is located outside the housing through the opening; the second end is connected to the winding segment and fixed to the winding component; one of the first carrier 310 and the second carrier 320 is fixed to the winding component, and the other of the first carrier 310 and the second carrier 320 is fixed to the housing; the conductive component of the first conductive component 100 and the second conductive component 200 disposed on the winding component is electrically connected to the second end; the conductive component of the first conductive component 100 and the second conductive component 200 disposed on the housing is electrically connected to the interface component.

[0064] In this embodiment, the winding member is rotatably connected to the housing. The first carrier 310 and the second carrier 320 are rotatably connected to the housing via the winding member. The first conductive member 100 and the second conductive member 200 are rotatably connected to the housing via the winding member. During the rotation of the winding member relative to the housing, the first conductive member 100 and the second conductive member 200 rotate relative to each other. The first protrusion 210 slides within the annular groove 130 and contacts the first annular side surface 110 and the second annular side surface 120, respectively, thereby keeping the first conductive member 100 and the second conductive member 200 electrically connected. This ensures that the cable and the interface are always electrically connected. Simultaneously, during the rotation of the winding member relative to the housing, the winding section wraps around the outside of the winding member or unwraps from it. The winding section can enter the receiving cavity through the opening of the housing or extend out of the receiving cavity through the opening of the housing, thereby adjusting the length of the cable and the distance between the interface and the first end of the cable. The first end of the cable and the interface can be electrically connected to electrical equipment, power supply equipment, and data transmission equipment, thereby adapting to electrical connections between devices with different spacings by adjusting the distance between the first end and the interface.
