Description

Technical Field

[0001] This utility model relates to the field of data cable technology, specifically to a data cable head structure, a data cable, and a power bank. Background Technology

[0002] In existing technologies, the data cable connector is often installed inside a metal cylinder, and the metal cylinder is tightly connected to the protective cover via a threaded structure to effectively protect the data cable connector. However, users need to rotate the cover multiple times to separate the protective cover from the metal cylinder, which is inefficient, especially in one-handed operation or emergency plugging / unplugging scenarios, affecting user experience. Furthermore, the threaded structure is prone to wear during long-term repeated use, leading to loosening of the connection between the protective cover and the metal cylinder, thus compromising its protective function and reducing the overall reliability and durability of the structure.

[0003] Therefore, existing technologies urgently need a protective structure that can both simplify operation and be used for a long time to meet the needs of users in diverse usage environments. Utility Model Content

[0004] In view of the above problems, this utility model provides a data cable connector structure, a data cable, and a power bank to solve the problem of inconvenient operation of existing data cable connector protection structures.

[0005] According to a first aspect of the present invention, a data cable header structure is provided, the data cable header structure comprising:

[0006] The protective housing is provided with a sliding channel;

[0007] The wire head body has a connecting terminal at one end and is connected to the wire body at the other end. The wire head body is slidably disposed in the sliding channel, so that the connecting terminal can switch between a retracted state and an extended state.

[0008] The limiting mechanism includes a limiting member, a driving structure, and a receiving groove provided on one of the wire end body and the protective housing, and a limiting groove provided on the other of the two. The limiting member is movably installed in the receiving groove, and the driving structure is placed on the protective housing or the wire end body. The driving structure is used to drive the limiting member to move out of the receiving groove.

[0009] The limiting groove includes a first limiting groove and a second limiting groove spaced apart along the sliding direction of the wire head body. When the connecting terminal is in the receiving state, the limiting member is at least partially placed in the first limiting groove; when the connecting terminal is in the extended state, the limiting member is at least partially placed in the second limiting groove.

[0010] In one alternative embodiment, the limiting element is a limiting magnetic element, and the driving structure includes a first magnetic element and a second magnetic element installed on the wire head body and respectively corresponding to the first limiting groove and the second limiting groove. The first magnetic element and the second magnetic element can be magnetically connected to the limiting element.

[0011] In one alternative embodiment, the receiving groove is disposed on the inner wall of the sliding channel, and a first mounting groove and a second mounting groove are provided at intervals along the sliding direction on the wire head body. The first magnetic component is placed in the first mounting groove, and the side surface of the first magnetic component away from the first mounting groove forms the bottom of the first limiting groove. The second magnetic component is placed in the second mounting groove, and the side surface of the second magnetic component away from the second mounting groove forms the bottom of the second limiting groove.

[0012] In one alternative embodiment, the driving structure includes a driving magnetic element mounted on the bottom of the receiving groove, and the limiting element is a limiting magnetic element. The driving magnetic element and the limiting magnetic element have the same magnetic poles at opposite ends, so that the limiting magnetic element is driven to move out of the receiving groove by the magnetic repulsion between the driving magnetic element and the limiting magnetic element.

[0013] In one alternative embodiment, the limiting groove includes a sliding groove disposed between the first limiting groove and the second limiting groove, the sliding groove being in communication with the first limiting groove and the second limiting groove respectively, and the bottom wall of the sliding groove being provided with a protruding pushing part.

[0014] In one alternative embodiment, the pressing part is provided with a first pressing surface, a top surface and a second pressing surface in sequence along the direction from the first limiting groove to the second limiting groove, and the protrusion height of the first pressing surface and the second pressing surface gradually decreases from one end near the top surface to the other end away from the top surface.

[0015] In one alternative approach, the length of the first pressing surface is greater than the length of the second pressing surface along the direction from the first limiting groove to the second limiting groove.

[0016] In one alternative embodiment, both the first limiting groove and the second limiting groove are provided with limiting walls on the side away from the sliding groove, and the height of the limiting walls is greater than the height of the top surface in a direction perpendicular to the sliding direction.

[0017] In one alternative, the direction of extension of the receiving groove depth is perpendicular to the direction of sliding of the wire head body within the sliding channel.

[0018] In one alternative embodiment, the wire head body has a front end face and a rear end face opposite to each other, the connecting terminal and the wire body are respectively connected to the front end face and the rear end face, and the protective housing has a front end face and a rear end face opposite to each other. When the connecting terminal is in the extended state, the front end face of the wire head body is flush with the front end face of the protective housing; when the connecting terminal is in the retracted state, the rear end face of the wire head body is flush with the rear end face of the protective housing.

[0019] In one alternative embodiment, the outer wall of the protective housing is provided with a booster portion near the rear end, the booster portion including a protruding structure protruding from the outer wall and / or a recessed structure recessed in the outer wall.

[0020] In one alternative embodiment, the driving structure further includes an elastic element disposed at the bottom of the receiving groove and connected to the limiting element. The limiting element has a first guide surface and a second guide surface on the side away from the bottom of the receiving groove. The first guide surface and the second guide surface are spaced apart at both ends of the limiting element along the sliding direction.

[0021] According to a first aspect of the present invention, a data cable is provided, the data cable including a cable body and at least one data cable head structure as described in any one of the first aspects above, the data cable head structure being connected to the cable body.

[0022] According to a first aspect of the present invention, a mobile power supply device is provided, the mobile power supply device including a data cable and a power body, the power body having a buckle, the data cable having a connector, one end of the data cable passing through the connector and the buckle in sequence, and then passing through the connector again to form a lanyard structure connected to the buckle.

[0023] In this embodiment of the invention, the wire head body is located within the sliding channel. When the wire head body slides within the sliding channel, one end with a connecting terminal extends from the front end of the protective housing to the outside of the protective housing, and the wire body passes through the sliding channel from the rear end of the protective housing and connects to the wire head body. When the connecting terminal is needed, external force is applied to both the protective housing and the wire body, causing the wire head body and the protective housing to slide relative to each other, and the connecting terminal extends out of the protective housing. After the connecting terminal is used, external force is applied to both the protective housing and the wire body, causing the protective housing and the wire head body to slide relative to each other, and the connecting terminal is retracted into the protective housing, protecting the connecting terminal from external impacts.

[0024] By placing one part of the limiting member in the receiving groove and the other part in the first limiting groove or the second limiting groove, the connection between the wire head body and the protective shell is fixed, ensuring that the protective shell and the wire head body will not slide arbitrarily when the connecting terminal is in the receiving state or the extended state, and the connecting terminal can be stably in the receiving state or the extended state when no external force is applied.

[0025] When the protective shell and the wire head body move relative to each other under the action of external force, the limiting member and the pushing part come into contact and are squeezed by the pushing part, causing the limiting member to move towards the bottom of the receiving groove, so that the limiting member is separated from the first limiting groove or the second limiting groove, releasing the fixed state of the protective shell and the wire head body, and the limiting member can smoothly slide into the second limiting groove or the first limiting groove.

[0026] This embodiment, by setting a limiting member corresponding to the receiving groove and a first limiting groove or a second limiting groove, can fix the position of the protective shell and the wire head body. At the same time, by setting a pushing part, the limiting member moves to the bottom of the receiving groove, releasing the fixed state of the protective shell and the wire head body, ensuring the smooth sliding of the limiting member, and realizing the extension or reception of the connecting terminal. The data cable head structure provided by this embodiment is simple, convenient and quick to operate, and improves the user experience.

[0048] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0049] Example 1

[0050] Please see Figure 1-9 , Figure 1 A perspective view of an embodiment of the data cable head structure 100 of this utility model is shown, as follows: Figure 1 As shown, the data cable head structure 100 includes: a protective housing 1, a cable head body 2, and a limiting mechanism; the protective housing 1 is provided with a sliding channel 11; one end of the cable head body 2 is provided with a connecting terminal 21, and the other end is connected to the cable body 4; the cable head body 2 is slidably disposed within the sliding channel 11, so that the connecting terminal 21 can switch between a retracted state and an extended state; as shown Figure 2 As shown, the limiting mechanism includes a limiting member 31, a driving structure, and a receiving groove 12 provided on one of the wire head body 2 and the protective housing 1, and a limiting groove provided on the other. The limiting member 31 is movably installed in the receiving groove 12, and the driving structure is placed in the protective housing 1 or the wire head body 2. The driving structure is used to drive the limiting member 31 to move out of the receiving groove 12. The limiting groove includes a first limiting groove 22 and a second limiting groove 23 spaced apart along the sliding direction of the wire head body 2. When the connecting terminal 21 is in the receiving state, the limiting member 31 is at least partially placed in the first limiting groove 22. When the connecting terminal 21 is in the extended state, the limiting member 31 is at least partially placed in the second limiting groove 23.

[0051] Specifically, the wire head body 2 is located within the sliding channel 11. When the wire head body 2 slides within the sliding channel 11, one end with the connecting terminal 21 extends from the front end 13 of the protective housing 1 to the outside of the protective housing 1, and the wire body 4 passes through the sliding channel 11 from the rear end 14 of the protective housing 1 and connects with the wire head body 2. When the user needs to use the connecting terminal 21, external force is applied to make the wire head body 2 and the protective housing 1 slide relative to each other, and the connecting terminal 21 extends to the outside of the protective housing 1, ensuring that the connecting terminal 21 can be used normally; after use, external force is applied to make the protective housing 1 and the wire head body 2 slide relative to each other, and the connecting terminal 21 is housed inside the protective housing 1, protecting the connecting terminal 21 from external impact.

[0052] The wire head body 2 and the protective housing 1 are connected by a limiting mechanism, allowing the connecting terminal 21 to smoothly extend into the protective housing 1 when needed and to be smoothly stored inside the protective housing 1 after use. When the limiting groove is located on the outer wall of the wire head body 2, the receiving groove 12 is located on the inner wall of the sliding channel 11 of the protective housing 1; conversely, when the limiting groove is located on the inner wall of the sliding channel 11 of the protective housing 1, the receiving groove 12 is located on the outer wall of the wire head body 2.

[0053] The first limiting groove 22, the second limiting groove 23, and the receiving groove 12 are correspondingly arranged. The positions of the limiting member 31 and the receiving groove 12, the first limiting groove 22, and the second limiting groove 23 define the positions, providing clear feedback to the user. The limiting member 31 is movably installed within the receiving groove 12, meaning the size of the receiving groove 12 is larger than the size of the limiting member 31, allowing the limiting member 31 to move smoothly along the depth direction of the groove within the receiving groove 12. Figure 2 As shown, when the first limiting groove 22 and the receiving groove 12 are aligned, the driving structure drives the limiting member 31 to move away from the bottom of the receiving groove 12 until the limiting member 31 and the bottom of the first limiting groove 22 are in contact. At this point, the limiting member 31 is partially placed in the first limiting groove 22 and partially placed in the receiving groove 12, thereby fixing the position of the protective housing 1 and the wire head body 2, ensuring that the connecting terminal 21 extending out of the protective housing 1 will not shake or slide back into the protective housing 1 at will.

[0054] Similarly, such as Figure 3 As shown, when the second limiting groove 23 and the receiving groove 12 are aligned, the limiting member 31 moves away from the bottom of the receiving groove 12 along the depth direction of the receiving groove 12 until the bottom of the limiting member 31 and the second limiting groove 23 come into contact. The driving structure drives the limiting member 31 to be partially placed in the second limiting groove 23 and partially placed in the receiving groove 12, thereby fixing the position of the protective housing 1 and the wire head body 2, ensuring that the connecting terminal 21 housed in the protective housing 1 cannot extend out of the protective housing 1 at will, and protecting the connecting terminal 21 from bumps or impacts.

[0055] like Figure 6 As shown, when the drive structure is installed in the limiting groove, it includes a first magnetic element 32 and a second magnetic element 33 installed in the lead body 2 and respectively corresponding to the first limiting groove 22 and the second limiting groove 23. The limiting element 31 is, for example, a limiting magnetic element. The first magnetic element 32 and the second magnetic element 33 can be magnetically connected to the limiting element 31 respectively. When the connecting terminal 21 is in the receiving state, the limiting element 31 is magnetically connected to the first magnetic element 32. When the connecting terminal 21 is in the extended state, the limiting element 31 is magnetically connected to the second magnetic element 33.

[0056] In one implementation, the first magnetic element 32 and the second magnetic element 33 are embedded in the wire head body 2 or the protective housing 1 to prevent the first magnetic element 32 and the second magnetic element 33 from moving or detaching from the wire head body 2 or the protective housing 1. This would prevent the protective housing 1 and the wire head body 2 from being misaligned when the receiving groove 12 and the limiting groove are misaligned, resulting in the connecting terminal 21 not extending or retracting properly. The first magnetic element 32 and the second magnetic element 33 are partially exposed outside the wire head body 2 or the protective housing 1, forming the bottom of the first limiting groove 22 and the bottom of the second limiting groove 23, respectively. This ensures that when the limiting groove and the receiving groove 12 are aligned, the first magnetic element 32 or the second magnetic element 33 attracts the limiting element 31 from the receiving groove 12 to the first magnetic element 32 or the second magnetic element 33 through magnetic force.

[0057] Another implementation involves providing a first mounting groove and a second mounting groove (not shown in the figure) spaced apart on the cable head body 2 or protective housing 1 along the sliding direction. A first magnetic component 32 is fixedly installed in the first mounting groove, with the side of the first magnetic component 32 away from the bottom of the first mounting groove forming the bottom of a first limiting groove 22. A second magnetic component 33 is fixedly installed in the second mounting groove, with the side of the second magnetic component 33 away from the bottom of the second mounting groove forming the bottom of a second limiting groove 23. By providing the first and second mounting grooves, it is ensured that the first magnetic component 32 and the second magnetic component 33 can be quickly installed in the correct position, improving the working efficiency of the data cable head structure 100 in factory production. Furthermore, the surfaces of the first magnetic component 32 and the second magnetic component 33 respectively form the bottoms of the first limiting groove 22 and the second limiting groove 23, ensuring close contact between the limiting component 31 and the first magnetic component 32 or the second magnetic component 33 when magnetically attracted, resulting in stronger magnetic attraction.

[0058] When the receiving groove 12 is provided on the inner wall of the sliding channel 11, the wire head body 2 is provided with a first mounting groove and a second mounting groove at intervals along the sliding direction. The first magnetic component 32 is placed in the first mounting groove, and the side surface of the first magnetic component 32 away from the first mounting groove forms the bottom of the first limiting groove 22. The second magnetic component 33 is placed in the second mounting groove, and the side surface of the second magnetic component 33 away from the second mounting groove forms the bottom of the second limiting groove 23.

[0059] like Figure 6As shown, when the first limiting groove 22 and the receiving groove 12 are aligned, the limiting member 31 and the first magnetic member 32 are magnetically connected to fix the protective housing 1 and the wire head body 2. When the user holds the protective housing 1 and plugs the connecting terminal 21 into the external electronic device, it ensures that the connecting terminal 21, which is placed outside the protective housing 1, will not slide into the protective housing 1 at will. When the second limiting groove 23 and the receiving groove 12 are aligned, the second magnetic member 33 and the first magnetic member 32 are magnetically connected to fix the protective housing 1 and the wire head body 2. It ensures that the connecting terminal 21, which is housed in the protective housing 1, will not slide out of the protective housing 1 at will, and that the connecting terminal 21 will not be damaged by bumps or impacts. At the same time, through the magnetic connection between the limiting member 31 and the first magnetic member 32 or the second magnetic member 33, the user can clearly know by hand whether the sliding between the protective housing 1 and the wire head body 2 is in place. That is, through the magnetic connection between the limiting member 31 and the first magnetic member 32 or the second magnetic member 33, the sliding position of the limiting member 31 can be fed back, and the user can know in time whether the force needs to be released.

[0060] When the limiting member 31 is magnetically connected to the first magnetic member 32 and the second magnetic member 33, the following configurations are possible: the limiting member 31 is a permanent magnet, and the first magnetic member 32 and the second magnetic member 33 are magnetically conductive materials; or, the limiting member 31 is a magnetically conductive material, and the first magnetic member 32 and the second magnetic member 33 are permanent magnets; or, the limiting member 31, the first magnetic member 32, and the second magnetic member 33 are all permanent magnets. Magnetic connection effectively prevents the limiting member 31 from accidentally detaching from the first limiting groove 22 or the second limiting groove 23 due to external vibration or collision, ensuring the stability of the connecting terminal 21 during use or storage. Furthermore, magnetic connection avoids mechanical friction wear between the limiting member 31 and the wire head body 2, significantly reducing structural wear during long-term use and extending service life.

[0061] In another implementation, the driving structure includes a driving magnetic component (not shown) mounted on the bottom of the receiving groove 12, and a limiting magnetic component 31. The driving magnetic component and the limiting magnetic component have the same magnetic poles at opposite ends, so that the limiting magnetic component is driven to move out of the receiving groove 12 by the magnetic repulsion between the driving magnetic component and the limiting magnetic component. The driving magnetic component is fixed to the bottom of the receiving groove 12. When the receiving groove 12 and the limiting groove are aligned, the limiting component 31 has room to move. The driving magnetic component drives the limiting magnetic component to move out of the receiving groove 12 by the magnetic repulsion until the bottom of the limiting magnetic component and the limiting groove abuts to limit the relative position of the protective housing 1 and the wire head body 2, so as to prevent the wire head body 2 from sliding relative to the protective housing 1 in the sliding channel 11, and ensure that the connecting terminal 21 is stably placed outside the protective housing 1 or completely contained in the protective housing 1.

[0062] In another implementation, the drive structure includes an elastic element (not shown in the figure), which is located at the bottom of the receiving groove 12 and a limiting element 31, allowing the limiting element 31 to move from the receiving groove 12 into the limiting groove. When the limiting groove and the receiving groove 12 are not aligned, the limiting element 31 is obstructed and cannot move out of the receiving groove 12, and the limiting element 31 presses against the elastic element, causing the elastic element to be in a compressed state. When the receiving groove 12 is aligned with the limiting groove, the limiting element 31 has space to move out of the receiving groove 12. Under the elastic force of the elastic element, the limiting element 31 moves towards the limiting groove until the limiting element 31 is partially placed in the limiting groove to limit the relative position of the wire head body 2 and the protective housing 1, ensuring that when the connecting terminal 21 is in the receiving state or the extended state, the wire head body 2 and the protective housing 1 will not move relative to each other arbitrarily.

[0063] When the connecting terminal 21 needs to switch between the retracted and extended states, the protective housing 1 and the wire head body 2 are subjected to external force. The limiting member 31 is pushed away from the limiting groove and moves towards the bottom of the receiving groove 12, squeezing the elastic member. The elastic member is compressed to increase the space of the receiving groove 12 to accommodate the limiting member 31 moving towards the bottom of the receiving groove 12, ensuring that the protective housing 1 and the wire head body 2 can slide smoothly relative to each other. This continues until the limiting member 31 is partially placed in the first limiting groove 22 or the second limiting groove 23 to limit the wire head body 2 and the protective housing 1, preventing them from sliding mechanically relative to each other.

[0064] Furthermore, such as Figure 3 and Figure 4 As shown, the limiting member 31 has a first guide surface 311 and a second guide surface 312 on the side away from the bottom of the receiving groove 12. The first guide surface 311 and the second guide surface 312 are spaced apart at both ends of the limiting member 31 along the sliding direction. In this embodiment, by setting the first guide surface 311 and the second guide surface 312 at the end of the limiting member 31 that contacts the wire head body 2, when the connecting terminal 21 needs to switch between the retracted state and the extended state, the limiting member 31 can smoothly disengage from the limiting groove through the first guide surface 311 and the second guide surface 312. This significantly reduces the operating resistance of the relative sliding between the protective shell 1 and the wire head body 2. At the same time, it accurately controls the limiting member 31 to slide into the first limiting groove 22 or the second limiting groove 23 along a predetermined trajectory, eliminating the risk of movement jamming. Furthermore, it ensures that the user can operate smoothly with one hand and also improves the service life of the high data cable head structure 100.

[0065] In another implementation, the protective shell 1 is made of an elastic material. In the depth direction of the receiving groove 12, the depth dimension of the receiving groove 12 is smaller than the thickness dimension of the limiting member 31. When the limiting member 31 is pressed into the receiving groove 12 by the pushing part 24, the limiting member 31 presses the bottom of the receiving groove 12. The bottom of the receiving groove 12 undergoes elastic deformation under pressure to increase the depth space for accommodating the limiting member 31. This allows the limiting member 31 to slide smoothly to the second limiting groove 23 or the first limiting groove 22 after it is disengaged from the first limiting groove 22 or the second limiting groove 23. When the receiving groove 12 and the limiting groove are aligned, the bottom of the limiting member 31 loses pressure, the deformed bottom of the receiving groove 12 recovers its shape, and the bottom of the receiving groove 12 presses the limiting member 31, driving the limiting member 31 to move towards the limiting groove until the limiting member 31 is partially placed in the limiting groove, thereby limiting the wire head body 2 and the protective shell 1 and preventing them from sliding mechanically relative to each other.

[0066] In one implementation, such as Figure 5 and Figure 6 As shown, the limiting groove includes a sliding groove 25 disposed between the first limiting groove 22 and the second limiting groove 23. The sliding groove 25 is connected to the first limiting groove 22 and the second limiting groove 23 respectively. The bottom wall of the sliding groove 25 is provided with a protruding pushing part 24.

[0067] By providing a sliding groove 25 between the first limiting groove 22 and the second limiting groove 23, the gap between the inner wall of the sliding channel 11 and the wire head body 2 in the area between the first limiting groove 22 and the second limiting groove 23 is increased. When the limiting member 31 slides in the area between the first limiting groove 22 and the second limiting groove 23, the pushing part 24 contacts the limiting member 31 and moves the limiting member 31 towards the bottom of the receiving groove 12, causing the limiting member 31 to disengage from the limiting groove. The setting of the sliding groove 25 makes the sliding of the limiting member 31 smoother, further improving the smoothness of the relative sliding between the protective shell 1 and the wire head body 2, reducing the resistance of the limiting member 31 sliding between the first limiting groove 22 and the second limiting groove 23, and ensuring that the user can smoothly perform the opening and closing operation of the connecting terminal 21 with one hand.

[0068] In one implementation, such as Figure 6 , Figure 7 and Figure 8 As shown, the pressing part 24 is provided with a first pressing surface 241, a top surface 243 and a second pressing surface 242 in sequence along the direction from the first limiting groove 22 to the second limiting groove 23. The protrusion height of the first pressing surface 241 and the second pressing surface 242 gradually decreases from the end near the top surface 243 to the end away from the top surface 243.

[0069] The pushing part 24 is disposed between the first limiting groove 22 and the second limiting groove 23 to prevent the limiting member 31 from disengaging from the limiting groove, ensuring that the connecting terminal 21 is stable in the extended or retracted state. When the connecting terminal 21 needs to be retracted into the protective housing 1, the pushing force acting on the limiting member 31 causes the limiting member 31 to slide along the second pushing surface 242 to the top surface 243. The inclined second pushing surface 242 can guide the limiting member 31 to smoothly transition from the second limiting groove 23 to the top surface 243, allowing the limiting member 31 to disengage from the second limiting groove 23. When the connecting terminal 21 needs to extend outside the protective housing 1, the pushing force acting on the limiting member 31 causes the limiting member 31 to slide along the first pushing surface 241 to the top surface 243. The inclined first pushing surface 241 can guide the limiting member 31 to smoothly transition from the first limiting groove 22 to the top surface 243, allowing the limiting member 31 to disengage from the first limiting groove 22.

[0070] Furthermore, such as Figure 7 and Figure 8 As shown, along the direction from the first limiting groove 22 to the second limiting groove 23, the length of the first pressing surface 241 is greater than the length of the second pressing surface 242. In this embodiment, by extending the sliding distance of the limiting member 31 on the first pressing surface 241, the slope of the first pressing surface 241 is reduced. When the user pinches the protective housing 1 and pushes the connecting terminal 21 outward from the protective housing 1, the limiting member 31 in the first limiting groove 22 can quickly slide to the top surface 243 and into the second limiting groove 23. The extended first pressing surface 241 reduces the resistance of the limiting member 31 to exit the first limiting groove 22 and move into the second limiting groove 23, ensuring that the user can more easily push the connector terminal out of the protective housing 1. The second pressing surface 242 is shorter, which increases the slope of the second pressing surface 242, thereby increasing the resistance of the limiting member 31 to detach from the second limiting groove 23. This prevents the limiting member 31 from moving directly into the first limiting groove 22 within the second limiting groove 23, thus preventing the connecting terminal 21 from easily retracting into the protective housing 1.

[0071] Furthermore, such as Figure 8 As shown, both the first limiting groove 22 and the second limiting groove 23 are provided with limiting walls on the side away from the sliding groove 25. The height of the limiting wall is greater than the height of the top surface 243 in the direction perpendicular to the sliding direction.

[0072] A first limiting wall 211 is provided on the side of the first limiting groove 22 away from the slide groove 25. When the limiting member 31 is partially placed in the first limiting groove 22, the first limiting wall 211 prevents the limiting member 31 from sliding further away from the second limiting groove 23, so that the connecting terminal 21 can be completely contained outside the protective housing 1, while ensuring that the wire head body 2 will not slide out of the protective housing 1 from the rear end 14, thus preventing the wire head body 2 from separating from the protective housing 1. A second limiting wall 212 is provided on the side of the second limiting groove 23 away from the slide groove 25. When the limiting member 31 is partially placed in the second limiting groove 23, the second limiting wall 212 prevents the limiting member 31 from sliding further away from the first limiting groove 22, so that the connecting terminal 21 can completely extend from the front end 13 of the protective housing 1 to the outside of the protective housing 1, but the wire head body 2 will not completely extend from the front end 13 to the outside of the protective housing 1.

[0073] Furthermore, such as Figure 9 As shown, the outer wall of the protective housing 1 near the rear end 14 has a protruding push-up portion 15. The push-up portion 15 includes a protruding structure protruding from the outer wall and / or a recessed structure recessed in the outer wall. The push-up portion 15 provides a point of force for the user to act on the protective housing 1. The user presses the push-up portion 15 with their fingers and applies force to move the connector body relative to the protective housing 1, improving the user's operating experience. The push-up portion 15 can be a convex strip-like structure on the outer wall of the protective housing 1, or a dotted circular protrusion structure on the outer wall of the protective housing 1, or multiple arc-shaped protruding ribs distributed on the outer wall of the protective housing 1, or multiple grooves spaced apart on the outer wall of the protective housing 1 along the sliding direction of the connector body 2.

[0074] Furthermore, the extension direction of the depth of the receiving groove 12 is perpendicular to the sliding direction of the wire head body 2 in the sliding channel 11, so as to fix the movement of the limiting member 31 and ensure that the wire head body 2 and the protective shell 1 will not easily slide relative to each other when no external force is applied.

[0075] Furthermore, the wire head body 2 is provided with a front end face 26 and a rear end face 27 opposite to each other. The connecting terminal 21 and the wire body 4 are respectively connected to the front end face 26 and the rear end face 27. The protective housing 1 is provided with a front end 13 and a rear end 14 opposite to each other. When the connecting terminal 21 is in the extended state, such as Figure 3 As shown, the front end face 26 of the cable head body 2 is flush with the front end 13 of the protective housing 1, with only the connecting terminal 21 exposed outside the protective housing 1. The cable head body 2 can be completely placed inside the protective housing 1, improving the overall aesthetics of the data cable head structure 100. When the connecting terminal 21 is in the receiving state, as... Figure 2 As shown, the rear end face 27 of the cable head body 2 is flush with the rear end 14 of the protective shell 1, which prevents the cable head body 2 from being exposed from the rear end 14 of the protective shell 1 and improves the overall aesthetics of the data cable head structure 100.

[0076] Example 2

[0077] Based on the data cable head structure 100 provided in Embodiment 1 above, Embodiment 2 provides a data cable 200, such as... Figure 10 As shown, the data cable 200 includes a cable body 4 and at least one data cable head structure 100 provided in any of the above embodiments 1, which is connected to the cable body 4. In this embodiment, by providing a data cable head structure 100 at at least one end of the cable body 4, an external force is applied to the protective housing 1, allowing the connection terminal 21 of the cable head body 2 to slide out of the protective housing 1 during use. After use, the connection terminal 21 is retracted into the protective housing 1, preventing the connection terminal 21 from being damaged by impact and improving the service life of the data cable 200.

[0078] In one implementation, such as Figure 11 As shown, each end of the cable body 4 along its length is provided with a data cable head structure 100. The two data cable head structures 100 are used to connect to two electronic devices to realize the current transfer between the two electronic devices. For example, the two electronic devices are a mobile phone and a power bank device 300. The connection terminals 21 in the two data cable head structures 100 are connected to the electrical interfaces of the mobile phone and the power bank device 300 respectively, so that the power bank device 300 can charge the mobile phone.

[0079] Example 3

[0080] Based on the data cable 200 provided in Embodiment 2, this embodiment provides a mobile power supply device 300, such as... Figure 12 As shown, the mobile power device 300 includes any of the data cables 200 provided in Embodiment 2 above and a power supply body 5. The power supply body 5 is provided with a buckle 6, and the data cable 200 is hung on the buckle 6.

[0081] In one implementation, the data cable 200 is provided with a connector 7. One end of the data cable 200 passes through the connector 7 and the buckle 6 in sequence, and then passes through the connector 7 again to form a lanyard structure and connect with the buckle 6. Each segment of the data cable 200 located on both sides of the buckle 6 passes through the through hole of the connector 7 to form a lanyard structure and connect with the buckle 6. At the same time, the size of the data head structure is larger than the size of the through hole to ensure that the data head structure will not slip out of the through hole, thereby fixing the data cable 200 and the buckle 6 and preventing the data cable 200 from falling off the buckle 6. This embodiment can ensure that the power supply body 5 and the data cable 200 will not separate, avoiding the inability to find the data cable 200 or the power supply body 5 when needed, thus improving the user experience. At the same time, the data cable 200 can be hung on the buckle 6 as a decoration, improving the aesthetics of the power bank device 300.
