Detailed Implementation

[0074] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0075] In the embodiments described in this application, it should be noted that, unless otherwise stated and limited, the term "connection" should be interpreted broadly. For example, it can be 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.

[0076] It should be noted that the terms "first," "second," and "third" used in the embodiments of this application 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 application described herein can be implemented in an order other than those illustrated or described herein.

[0077] The following combination Figures 1 to 14 The retractable data cable and the retractable data cable described in the embodiments of this application will be described in detail.

[0078] like Figures 1 to 3 As shown in the illustration, this application describes a retractable data cable reel, comprising: a winding member 230, a first positioning structure 210, and a second positioning structure 220. The winding member 230 has a first end and a second end disposed opposite to each other in the axial direction; the first positioning structure 210 is disposed at the first end of the winding member 230; the second positioning structure 220 is disposed at the second end of the winding member 230; the second positioning structure 220 is different from the first positioning structure 210.

[0079] In related technologies, data cable structures include rotating structures; these rotating structures enable the extension and retraction of the cable structure. However, the limiting structure of the rotating structure is simple, resulting in poor adaptability of the data cable structure. The retractable data cable reel of this application includes a first positioning structure 210 and a second positioning structure 220, and the first positioning structure 210 and the second positioning structure 220 are different, allowing the retractable data cable to have different limiting structures, thereby greatly improving the adaptability of the retractable data cable.

[0080] like Figure 4 and Figure 5As shown in the illustration, this application also describes a retractable data cable, including the swivel 200 of this application embodiment. The retractable data cable further includes a housing 100 and a cable 300. The housing 100 has a receiving cavity 101 and at least one opening 102 communicating with the receiving cavity 101; the swivel 200 is rotatably disposed within the receiving cavity 101; the cable 300 may include a winding section 310 and at least one end. The winding section 310 is used to wind around a winding member 230; at least one end is connected to the winding section 310 and is located outside the housing 100 through at least one opening 102.

[0081] like Figures 6 to 10 As shown, the retractable data cable may also include a first mating structure 400, which is movably disposed in the housing 100 and is used to cooperate with the first positioning structure 210 to limit the rotation position of the wheel 200; thus, the rotation position of the wheel 200 can be limited by the cooperation of the first mating structure 400 and the first positioning structure 210.

[0082] like Figures 11 to 14 As shown, the retractable data cable may further include a second mating structure 500, which is movably disposed in the housing 100 and used to engage with the second positioning structure 220 to limit the rotational position of the rotating wheel 200; thus, the rotational position of the rotating wheel 200 can be limited by the engagement of the second mating structure 500 and the second positioning structure 220. Here, the structure of the retractable data cable that limits the rotational position of the rotating wheel 200 is the same as described above. Figures 6 to 10 The retractable data cable has a different structure for limiting the rotation position of the rotating wheel 200, but the two types of retractable data cables can be used interchangeably. Figures 1 to 3 Using the same rotating wheel 200 reduces the development costs of both types of retractable data cables; it also reduces the number of parts in both types of retractable data cable products, thus reducing the management costs of these parts. If the rotating wheel 200 is formed by injection molding, it also reduces the number of molds needed to produce both types of retractable data cables, thereby lowering the manufacturing cost of both types of retractable data cables.

[0083] In this embodiment, two types of retractable data cables can share the same housing or use different housings. When two retractable data cables share the same housing, the development cost of both types of retractable data cables can be further reduced; the number of parts in the two types of retractable data cable products can also be further reduced, further reducing the management cost of the parts. If the housing is formed by injection molding, the number of molds used to produce the two types of retractable data cables can be further reduced, further reducing the manufacturing cost of the two types of retractable data cables. This application mainly uses the example of two retractable data cables sharing the same housing for illustration. Of course, the two retractable data cables can also not share the same housing, and this application does not limit this.

[0084] In the embodiments of this application, the structure of the housing 100 is not limited. For example, in some embodiments, the housing 100 can be a cuboid structure. In other embodiments, the housing 100 can be an elliptical structure.

[0085] As an example, such as Figure 4 and Figure 5 As shown, the housing 100 may include a first half-shell 110 and a second half-shell 120, which are fixedly connected to the first half-shell 110 by means of a snap-fit ​​structure, a threaded structure, an adhesive structure, etc. Here, an opening 102 and a receiving cavity 101 may be defined between the second half-shell 120 and the first half-shell 110. Of course, in some other examples, two openings may also be defined between the second half-shell 120 and the first half-shell 110.

[0086] In the embodiments of this application, the structure of the rotating wheel 200 is not limited. For example, in some embodiments, the rotating wheel 200 can be a columnar structure. In other embodiments, the rotating wheel 200 can be a ring-shaped structure.

[0087] The implementation method in which the rotating wheel 200 is rotatably disposed within the receiving cavity 101 is not limited. For example, in some embodiments, the rotating wheel 200 can be rotatably disposed within the receiving cavity 101 via a rotating shaft structure. As an example, a connecting post 122 may be provided within the receiving cavity 101, and the rotating wheel 200 may have a first connecting hole 201, such as... Figure 7 and Figure 12 As shown, the connecting post 122 passes through the first connecting hole 201 and is rotatable within the first connecting hole 201; thus, by means of the connecting post 122 passing through the first connecting hole 201, the rotating wheel 200 is rotatably disposed within the receiving cavity 101. Here, as... Figure 10 and Figure 14As shown, the connecting post 122 can be fixed to the second half-shell 120. Alternatively, the connecting post 122 and the second half-shell 120 can be a single structural component; here, the connecting post 122 and the second half-shell 120 can be integrally molded by injection molding. The connecting post 122 can also be connected to the first half-shell 110, and the connecting post 122 and the first half-shell 110 can be connected by fasteners. The structure of the fasteners is not limited. For example, the fastener can be a screw. Alternatively, the connecting post 122 can also be fixed to the first half-shell 110, and the connecting post 122 and the first half-shell 110 can be a single structural component; here, the connecting post 122 and the first half-shell 110 can also be integrally molded by injection molding.

[0088] In this embodiment, the first positioning structure 210 can be disposed on the first end of the winding member 230 by means of bonding, welding, or snap-fitting. The first positioning structure 210 and the winding member 230 can also be different parts of the same structural member.

[0089] The first positioning structure 210 can be disposed on the end face side of the winding member 230 or on the periphery side of the winding member 230.

[0090] The form of the first positioning structure 210 is not limited. For example, the first positioning structure 210 may have at least one groove 211. Here, the number of grooves 211 is not limited. As an example, such as Figure 1 As shown, the first positioning structure 210 can be located on the end face side of the rotating wheel 200 and at the axis of the rotating wheel 200; the number of grooves 211 is at least two, and the at least two grooves 211 are arranged circumferentially spaced along the first positioning structure 210; so that the rotating wheel 200 can be positioned by the at least two grooves 211. Of course, the first positioning structure 210 may also not have grooves 211. The surface of the first positioning structure 210 can engage with the surface of the first mating structure 400 to limit the rotational position of the rotating wheel 200.

[0091] The second positioning structure 220 can be attached to the second end of the winding member 230 by means of bonding, welding, or snap-fit. The second positioning structure 220 and the winding member 230 can also be different parts of the same structural member.

[0092] The second positioning structure 220 can be disposed on the end face side of the winding member 230 or on the periphery side of the winding member 230.

[0093] The form of the second positioning structure 220 is not limited. For example, such as Figure 2 and Figure 3As shown, the second positioning structure 220 may have: an inner annular slide 221, an outer annular slide 222, a sliding in channel 223, a sliding out channel 224, and a slot 225; the outer annular slide 222 and the inner annular slide 221 are radially spaced apart on the rotating wheel 200; the sliding in channel 223 communicates with both the inner annular slide 221 and the outer annular slide 222; the sliding out channel 224 communicates with both the inner annular slide 221 and the outer annular slide 222; and the slot 225 is located at the sliding in channel 223. Alternatively, the surface of the second positioning structure 220 may also engage with the surface of the second mating structure 500 to limit the rotational position of the rotating wheel 200.

[0094] The second positioning structure 220 is different from the first positioning structure 210. The way the second positioning structure 220 is coupled with the second mating structure 500 can be different from the way the first positioning structure 210 is coupled with the first mating structure 400, thereby providing different limiting structures for the wheel 200.

[0095] Example 1, such as Figure 1 As shown, the winding member 230 may include: a winding portion 231, a first plate portion 232, and a second plate portion 233. The winding portion 231 has a first end and a second end that are disposed opposite each other in the axial direction; the first plate portion 232 is disposed at the first end of the winding portion 231; a first positioning structure 210 is disposed at the first plate portion 232; the second plate portion 233 is disposed at the second end of the winding portion 231; a second positioning structure 220 is disposed at the second plate portion 233; a winding space is defined between the winding portion 231, the first plate portion 232, and the second plate portion 233, so that the cable 300 is wound outside the winding portion 231 and located within the winding space, thereby making the cable 300 wound on the winding member 230 neater.

[0096] In Example 1, the winding portion 231 can be a cylindrical structure so that the elastic element 630 is disposed within the cavity defined by the winding portion 231; here, the elastic element 630 can be connected to both the winding member 230 and the housing 100 to provide a restoring force to the winding member 230 in the direction of rotating in the cable receiving direction. The elastic element 630 can be a torsion spring.

[0097] In Example 1, in order to install the elastic member 630 into the cavity defined by the winding portion 231, one of the first plate portion 232 and the second plate portion 233 can be provided as a separate structure, or both the first plate portion 232 and the second plate portion 233 can be provided as separate structures.

[0098] In Example 1, the first plate portion 232 may include a first annular portion 2321 and a first stop portion 2322 detachably disposed at a through hole in the first annular portion 2321; the first annular portion 2321 is connected to a first end of the winding portion 231, and the through hole of the first annular portion 2321 communicates with the cavity defined by the winding portion 231; so that the elastic member 630 is disposed in the cavity defined by the winding portion 231 through the through hole of the first annular portion 2321.

[0099] Here, the first stop 2322 can be detachably installed at the through hole of the first annular part 2321 by means of plug-in, snap-fit, threaded structure, etc.

[0100] Here, the first positioning structure 210 can be attached to the first stop 2322 by bonding or welding. Of course, the first positioning structure 210 and the first stop 2322 can also be different parts of the same structural component. By placing the first positioning structure 210 in the smaller first stop 2322, it is easier to process and manufacture.

[0101] In Example 1, the second plate portion 233 may include a second annular portion and a second stop portion detachably disposed at a through hole in the second annular portion; the second annular portion is connected to the second end of the winding portion 231, and the through hole in the second annular portion communicates with the cavity defined by the winding portion 231; so that the elastic member 630 is disposed in the cavity defined by the winding portion 231 through the through hole in the second annular portion.

[0102] Here, the second stop can be detachably installed at the through hole of the second annular part through a plug-in, snap-fit, or threaded structure.

[0103] Here, the second positioning structure 220 can be attached to the second stop portion by means of bonding, welding, or other methods. Alternatively, the second positioning structure 220 and the second stop portion can be a single structural component. The second positioning structure 220 can also be attached to the second annular portion by means of bonding, welding, or other methods. Alternatively, the second positioning structure 220 and the second annular portion can be a single structural component. The second positioning structure 220 can also be attached to both the second stop portion and the second annular portion simultaneously by means of bonding, welding, or other methods.

[0104] Here, the second positioning structure 220 is provided in the smaller second stop and / or second annular portion to facilitate processing.

[0105] In Example 1, the first positioning structure 210 may be located on the end face side of the first plate portion 232 away from the second plate portion 233; the first positioning structure 210 may have at least one groove 211.

[0106] In Example 1, the second positioning structure 220 may be located on the end face of the second plate portion 233 away from the first plate portion 232; the end face of the second positioning structure 220 away from the winding member 230 may be provided with: an inner annular slide 221, an outer annular slide 222, a sliding in channel 223, a sliding out channel 224 and a slot 225.

[0107] In this embodiment, the length of the cable 300 can be increased by stretching one end or by stretching both ends. As an example, for instance... Figure 4 and Figure 5 As shown, the housing 100 has an opening 102, where an opening 102 and a receiving cavity 101 can be defined between the second half-shell 120 and the first half-shell 110.

[0108] In this embodiment, the form of the first mating structure 400 is not limited. For example, the first mating structure 400 can be a strip-shaped structure, the first mating structure 400 can be movably disposed on the housing 100, and the first mating structure 400 can move to engage with the surface of the first positioning structure 210 or the groove 211 of the first positioning structure 210 to limit the rotation position of the rotating wheel 200.

[0109] In this embodiment, the structure of the second mating structure 500 is not limited. For example, the second mating structure 500 can be a strip-shaped structure, the second mating structure 500 can be movably disposed on the housing 100, and the second mating structure 500 can move to engage with the surface of the second positioning structure 220 or the slot 225 of the second positioning structure 220 to limit the rotation position of the rotating wheel 200.

[0110] In some optional implementations of this application, the first positioning structure 210 is located at the axis on the first end face side of the winding member 230; the first positioning structure 210 may have at least two grooves 211 spaced circumferentially along the first positioning structure 210, such as... Figure 7 As shown; the first mating structure 400 may include: a connector 410, a limiting gear 420, and a reset member 430, such as Figure 8 , Figure 9 and Figure 10 As shown; so that the rotational position of the rotating wheel 200 is limited by the connector 410, the limiting gear 420 and the reset member 430.

[0111] In this implementation, the number of grooves 211 is not limited. For example, as Figure 7 As shown, there are four grooves 211, and the four grooves 211 can be evenly arranged along the circumference of the first positioning structure 210.

[0112] In this implementation, the connector 410 can be rotatably connected to the housing 100 via a pivot structure; the peripheral side of the connector 410 may have a first protrusion 411; the first protrusion 411 is used to engage with at least two grooves 211; when the first protrusion 411 is located within one groove 211 and the connector 410 no longer rotates, the wheel 200 no longer rotates relative to the housing 100. When the first protrusion 411 is located outside at least two grooves 211, the connector 410 does not affect the rotation of the wheel 200.

[0113] The end of the connector 410 facing the rotating wheel 200 may also have two spaced-apart second protrusions 412 and third protrusions 413; the limiting gear 420 can be rotatably connected to the housing 100 through a rotating shaft structure and is located between the second protrusion 412 and the third protrusion 413; the limiting gear 420 is used to cooperate with the second protrusion 412 or the third protrusion 413 to limit the swing position of the connector 410.

[0114] Here, the structure of the limiting gear 420 is not limited, as long as the limiting gear 420 can cooperate with the second protrusion 412 or the third protrusion 413 so that the first protrusion 411 is outside the groove 211 when the cable 300 is stretched, and the first protrusion 411 is inside the groove 211 after the cable 300 is stretched to a certain length.

[0115] For example, such as Figure 7 and Figure 8 As shown, the limiting gear 420 may include: a first side surface 421, a first tooth groove 422, and a second tooth groove 423. The first tooth groove 422 and the second tooth groove 423 are used to mate with the second protrusion 412; the first side surface 421 is used to mate with the second side surface 4131 of the third protrusion 413; wherein, the depth of the first tooth groove 422 is greater than the depth of the second tooth groove 423, and the distance between the first tooth groove 422 and the axis of the limiting gear 420 is less than the distance between the second tooth groove 423 and the axis of the limiting gear 420; in the stretched state, the first side surface 421 and the second side surface 4131 are arranged adjacent to each other; in the positioned state, the second protrusion 412 is located within the second tooth groove 423; in the retracted state, the second protrusion 412 is located within the first tooth groove 422.

[0116] In this implementation, the reset member 430 can be connected to the housing 100 through a snap-fit ​​structure, adhesive structure, etc.; the reset member 430 is used to provide a restoring force to the connector 410.

[0117] Here, the structure of the reset member 430 is not fixed. For example, the reset member 430 can be a spring-loaded structure, so that the connecting member 410 can be in a position that engages with the limit gear 420.

[0118] During use, in the stretched state, external force overcomes the deformation force of the elastic element 630 to pull the cable 300. The cable 300 drives the rotating wheel 200 to rotate in the stretching direction, and the length of the cable 300 increases. At this time, the first protrusion 411 is outside the groove 211. When the cable 300 is pulled to a suitable length, the external force is removed, and the rotating wheel 200 rotates in the retracting direction under the deformation force of the elastic element 630. When the rotating wheel 200 rotates to the side where the groove 211 faces the connector 410, the reset element 430 provides a force to the connector 410 to rotate in the first direction, causing the first protrusion 411 to... Located within the groove 211, and simultaneously, in the stretched state, due to the adjacent arrangement of the first side 421 and the second side 4131, the connector 410 also pushes the limiting gear 420 to rotate. When the connector 410 rotates until the second protrusion 412 is located within the second tooth groove 423, the limiting gear 420 prevents the connector 410 from rotating. Since the first protrusion 411 is located within the groove 211, at this time, the resistance of the first protrusion 411 to the rotating wheel 200 is greater than the force provided by the elastic member 630 for the rotating wheel 200 to rotate in the receiving direction, thereby causing the connector 410 to be in a position where the first protrusion 411 is located within the groove 211. The positioning state within 11 ensures that the cable 300 is stably at the appropriate length. When it is necessary to store the cable 300 inside the housing 100, the cable 300 can be pulled again by external force. The cable 300 drives the rotating wheel 200 to rotate in the stretching direction, thereby causing the first protrusion 411 to disengage from the groove 211. At the same time, since the second protrusion 412 is located in the second tooth groove 423, the connector 410 will push the limiting gear 420 to rotate to the position where the second protrusion 412 corresponds to the first tooth groove 422. When the external force is removed, the first protrusion 411 will be located in the groove 211 again, and the rotating wheel... The first protrusion 411 will drive the connector 410 to rotate a certain angle in the first direction. When the connector 410 rotates to the point where the second protrusion 412 is located in the first tooth groove 422, since the depth of the first tooth groove 422 is greater than the depth of the second tooth groove 423, the first protrusion 411 is located outside the groove 211. At this time, the connector 410 cannot prevent the rotating wheel 200 from rotating through the first protrusion 411. The rotating wheel 200 rotates continuously in the storage direction under the action of the elastic member 630 until the part of the cable 300 that can be coiled outside the rotating wheel 200 is completely coiled outside the rotating wheel 200.When the length of cable 300 needs to be adjusted, external force can be used to overcome the deformation force of elastic element 630 and pull cable 300. Cable 300 drives wheel 200 to rotate in the stretching direction. When wheel 200 rotates until groove 211 faces connector 410, first protrusion 411 enters groove 211. Wheel 200 can drive connector 410 to rotate in the second direction through first protrusion 411. At the same time, since second protrusion 412 is located in first tooth groove 422, connector 410 can push limit gear 420 to rotate at a certain angle. When wheel 200 drives connector 410 to rotate in the second direction through first protrusion 411 until first protrusion 411 is outside groove 211, data cable storage device is in the stretched state again. At this time, first side 421 and second side 4131 are arranged adjacent to each other. The data cable storage device can repeat the above process during use, switching between stretched state, positioning state and storage state in sequence to facilitate use of data cable storage device. Here, the first direction and the second direction are opposite, and the storage direction and the stretching direction are opposite.

[0119] Here, the first protrusion 411 makes a sound when it enters or leaves the groove 211, providing the operator with a audible limiting structure.

[0120] In this implementation, the housing 100 may have a first connecting structure 130 connected to the first mating structure 400, so that the first mating structure 400 can be connected to the housing 100 through the first connecting structure 130. The form of the first connecting structure 130 is not limited.

[0121] For example, such as Figure 8 and Figure 9 As shown, the first connecting structure 130 may include a first connecting portion 131, a second connecting portion 132, and a third connecting portion 133. The first connecting portion 131 may be located on one side of the axis of the rotating wheel 200; the first connecting portion 131 is rotatably connected to the connecting member 410; the second connecting portion 132 may be located on the side of the first connecting portion 131 near the axis of the rotating wheel 200; the second connecting portion 132 may be rotatably connected to the limiting gear 420; the third connecting portion 133 may be located on one side of the axis of the rotating wheel 200; the third connecting portion 133 is connected to the reset member 430.

[0122] In this example, the first connecting portion 131 can be a columnar structure or a perforated structure. The second connecting portion 132 can be a columnar structure or a perforated structure. The third connecting portion 133 can be a strip-shaped structure. The number of third connecting portions 133 is not limited. As an example, such as Figure 8 and Figure 9As shown, there are two third connecting parts 133. The two third connecting parts 133 are respectively connected to the two ends of the reset member 430, and the middle part of the reset member 430 can contact the side of the connecting member 410.

[0123] In this implementation, the housing 100 includes a first wall 111 and a second wall 121 disposed opposite to each other along the axial direction of the rotating wheel 200; the first wall 111 may have a first connecting structure 130 on the side facing the second wall 121, such as... Figure 8 and Figure 9 As shown; the second wall 121 facing the first wall 111 may have a second connection structure 140, such as Figure 13 As shown, the second connecting structure 140 can be connected to the second mating structure 500, which in turn mates with the second positioning structure to limit the rotational position of the wheel 200 relative to the housing; thus achieving a common housing 100 for both types of retractable data cables. It should be noted that... Figures 6 to 10 The corresponding retractable data cable does not have a second mating structure 500 installed.

[0124] In some optional implementations of the embodiments of this application, such as Figure 13 As shown, the second positioning structure 220 can be located on the second end face side of the winding member 230; the end face side of the second positioning structure 220 away from the winding member 230 is provided with: an inner annular slide 221, an outer annular slide 222, a sliding in channel 223, a sliding out channel 224, and a slot 225; the outer annular slide 222 and the inner annular slide 221 are radially spaced apart on the rotating wheel 200; the sliding in channel 223 communicates with the inner annular slide 221 and the outer annular slide 222 respectively; the sliding out channel 224 communicates with the inner annular slide 221 and the outer annular slide 222 respectively; the slot 225 is located at the sliding in channel 223. The second mating structure 500 is rotatably connected to the housing 100, and the end face of the second mating structure 500 facing the rotating wheel 200 has a limiting protrusion 510, such as Figure 13 and Figure 14 As shown; the limiting protrusion 510 is used to cooperate with the slot 225 to limit the rotational position of the rotating wheel 200 relative to the housing.

[0125] In this implementation, the limiting protrusion 510 can slide within the inner annular slide 221, the outer annular slide 222, the sliding in channel 223, and the sliding out channel 224. When the limiting protrusion 510 slides to engage with the slot 225, the rotating wheel 200 stops rotating, thereby allowing the cable 300 to be at a suitable pull-out length.

[0126] During use, when the cable 300 is stretched by external force, the limiting protrusion 510 slides in the outer annular slide 222. When the cable 300 is stretched to a suitable length, the external force is removed, and the rotating wheel 200 rotates in the opposite direction under the action of the elastic element 630. The limiting protrusion 510 enters the slot 225 from the sliding in channel 223, and the rotating wheel 200 stops rotating. When the rotating wheel 200 is gently pulled and released, the limiting protrusion 510 enters the inner annular slide 221 from the sliding in channel 223 and rotates in the opposite direction under the action of the elastic element 630. The limiting protrusion 510 slides in the inner annular slide 221 until the cable 300 is fully retracted. Because the limiting protrusion 510 can slide within the inner annular slide 221, outer annular slide 222, sliding in channel 223, and sliding out channel 224, no loud noise occurs during the stretching or retraction of the cable 300. Here, the second positioning structure 220 and the second mating structure 500 work together to create a limiting structure similar to a silent one. Figures 6 to 10 The retractable data cable features a audible sound when the first protrusion 411 enters or exits the groove 211, providing an audible limiting structure for the operator. These two types of retractable data cables offer users more options, significantly improving the adaptability of the retractable data cable.

[0127] In this implementation, the housing 100 may include a first wall 111 and a second wall 121 disposed opposite to each other along the axial direction of the rotating wheel 200; the second wall 121 has a second connecting structure 140 on the side facing the first wall 111, such as... Figure 13 As shown, the second connecting structure 140 is rotatably connected to the second mating structure 500; the first wall 111 has a first connecting structure 130 on the side facing the second wall 121; the first connecting structure 130 is used to connect with the first mating structure 400, and the first mating structure 400 is used to mate with the first positioning structure 210 to limit the rotational position of the wheel 200 relative to the housing; thereby realizing that the two types of telescopic data cables share the same housing 100. It should be noted that... Figures 11 to 14 The first mating structure 400 is not installed in the corresponding retractable data cable.

[0128] In one application, the retractable data cable can be provided with a limiting structure through the second positioning structure 220 and the second mating structure 500. However, the retractable data cable can also use the first mating structure 400 as an accessory. Here, when the user wants to use the first mating structure 400 for limiting, the first mating structure 400 can be installed on the housing 100, and the second mating structure 500 can be removed and used as an accessory; thereby greatly improving the adaptability of the retractable data cable.

[0129] In some optional implementations of the embodiments of this application, such as Figure 4 and Figure 6As shown, the retractable data cable may further include: a circuit board 610 which can be attached to the second end of the winding member 230 by means of bonding, snapping, etc., and is electrically connected to the first end 320 of the cable 300; the second end 330 of the cable 300 is located outside the housing 100 through the opening 102; the interface member 620 can be attached to the housing 100 by means of bonding, snapping, etc., and is electrically connected to the circuit board 610; the interface portion 621 of the interface member 620 is exposed through the slot 103 of the housing 100.

[0130] The method of electrically connecting the interface component 620 and the circuit board 610 is not limited. For example, one of the interface component 620 and the circuit board 610 is provided with at least one annular groove, and the other of the interface component 620 and the circuit board 610 is provided with a conductive protrusion inserted into the annular groove, and a conductive part electrically connected to the conductive protrusion is provided in the annular groove. When the winding component 230 rotates relative to the housing 100, the conductive protrusion slides in the annular groove and is electrically connected to the conductive part.

[0131] The interface portion 621 is a conductive structure. The interface portion 621 can be electrically connected to either a power supply device or a user device. The second end 330 of the cable 300 can also be electrically connected to either a power supply device or a user device.

[0132] When the winding member 230 rotates relative to the housing 100, the cable 300 extends out of the housing 100 or retracts into the housing 100 through the opening 102 to adjust the distance between the second end 330 of the cable 300 and the interface portion 621.

[0133] It should be noted that when the retractable data cable is Figures 8 to 14 In the case of a corresponding retractable data cable, the circuit board 610 and the second mating structure 500 are spaced apart, such as... Figure 11 As shown, this is to prevent the circuit board 610 and the second mating structure 500 from interfering with each other.

[0134] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0135] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
