Description

Technical Field

[0001] This utility model relates to the field of electronic device charging technology, and in particular to a cable reel. Background Technology

[0002] With the rapid development and innovation of modern mobile devices, different mobile devices generally use their own interfaces or charging ports. In the same space, when multiple mobile devices are used, their data cables can easily get tangled together if they are not properly organized. Therefore, cable winders with multiple different interfaces have emerged, which can connect multiple mobile devices at the same time and can rewind the data cables.

[0003] During the cable pulling process, the impact force on the reel mainly comes from when the cable is pulled to its maximum length. Excessive stretching during the pulling process can lead to the following problems:

[0004] 1. Conductor breakage and contact surface damage: The conductor inside the wire breaks due to exceeding the tensile strength of the material, causing power outage or equipment failure;

[0005] 2. Damage to shielding and insulation layers: Excessive tensile force may cause cracks or damage to the insulation layer of the wire due to mechanical stress, leading to safety hazards such as leakage and short circuit, as well as disrupting the uniform distribution of the electric field and increasing the risk of breakdown;

[0006] 3. Structural deformation and core wire displacement: Long-term or instantaneous excessive tension can cause core wire displacement, reduced sheath wrapping force, and even permanent structural deformation, reducing the cable's flexibility and durability;

[0007] 4. Loose joints and overheating: Concentrated tension at the joints can easily lead to loose connections, causing poor contact, sparks, or localized overheating, thus increasing the risk of fire.

[0008] 5. Accelerated wire wear: Repeatedly bearing excessive tensile force will accelerate the fatigue wear of the wire sheath and internal materials, shortening the overall service life. Utility Model Content

[0009] The technical problem to be solved by this utility model is to avoid the risk of breakage or damage to the interface between the wire and the take-up reel due to excessive tension during the wire pulling process. To this end, a wire reel is provided that can buffer the tension at the interface when the wire is pulled to its limit.

[0010] The technical solution adopted by this utility model to solve its technical problem is: a wire reel, including a housing, a conductive wire and a take-up reel, the take-up reel being sleeved in the housing, the take-up reel including a spool, the spool having a first opening and a second opening, the conductive wire being wound around the spool, one end of the conductive wire connecting to the take-up reel passing through the first opening, and the conductive wire having a glue-locking opening, the glue-locking opening being locked in the second opening.

[0011] Preferably, the reel has a first hollow structure, and the conductive wire passes through the first opening and then through the first hollow structure.

[0012] Preferably, the take-up reel is provided with a first fixing groove near the second opening, and the conductive wire portion is disposed in the first fixing groove.

[0013] Preferably, the take-up reel is further provided with a reinforcing rib corresponding to the first fixing groove, and the conductive wire is clamped between the reel and the reinforcing rib.

[0014] Preferably, the adhesive inlet is integrally formed with the conductive wire, and the adhesive inlet protrudes from the outer surface of the conductive wire.

[0015] Preferably, the adhesive outlet is elastic.

[0016] A cable reel includes a housing, a take-up reel, and a conductive wire. The take-up reel is movably mounted on the housing, and the conductive wire is housed in the take-up reel. The take-up reel has a second fixing groove, and the conductive wire has an adhesive outlet, which is fixed to the second fixing groove.

[0017] Preferably, the adhesive outlet has a second hollow structure, and the conductive wire is interference-fitted with the second hollow structure.

[0018] Preferably, the adhesive outlet has a sheet-like structure.

[0019] Preferably, the glue inlet has an arc, and the arc is consistent with the take-up reel.

[0020] The following are the beneficial effects of implementing this utility model:

[0021] The cable reel provided by this utility model has two aspects. First, the conductive wire extends into the inside of the reel through a first opening and is fixedly connected inside. The connection port of the conductive wire can reduce local tension and concentrate part of the pulling force into stable support, avoiding excessive stretching caused by uneven force during dynamic movement. Second, the conductive wire has a retaining opening fixed to the second opening, so that the conductive wire is fixed to the reel. The pulling force on the conductive wire is transmitted to the retaining opening, which is blocked by the reel, buffering the tension at the connection port of the conductive wire. This avoids the conductive wire being broken due to excessive pulling force by the user, which could lead to circuit interruption or equipment failure, or damage to the shielding or insulation layer of the conductive wire, causing safety hazards such as leakage and short circuit, as well as disrupting the uniform distribution of the electric field and increasing the risk of breakdown.

[0038] Example 1:

[0039] Please see Figures 1-4This embodiment provides a cable reel 100, including a housing 10, a take-up reel 20, and a conductive wire 30. The take-up reel is fitted inside the housing 10. The take-up reel 20 includes a spool 21 and a base 22. The outer side 211 of the spool 21, the base, and the housing 10 form a storage space for the conductive wire 30. The conductive wire 30 is stored in the storage space around the outer side of the spool 21. The inner side 212 of the spool provides a second space for installing other components. Specifically, the spool 21 has a first opening 201 and a second opening 202. A portion of the conductive wire 30 passes through the first opening 201, that is, a portion of the conductive wire 30 is located on the inner side 212 of the spool 21, and the other portion is coiled around the outer side 211 of the spool 21. Unlike existing technologies, the connection port of the conductive wire 30 is not connected on the outer surface 211 of the reel 21, but on the inner surface 212. This reduces local tension at the connection port of the conductive wire 30, concentrating some of the tensile force into stable support and preventing excessive stretching due to uneven stress during dynamic movement. Furthermore, placing the connection port of the conductive wire 30 on the inner surface 212 of the reel 21 prevents material fatigue and breakage at the connection point caused by repeated bending or friction.

[0040] In addition, the conductive wire 30 is provided with a glue opening 31, which protrudes from the outer surface of the conductive wire 30. The spool 21 is divided into at least two parts by the first opening 201 and the second opening 202: a first part 21A and a second part 21B. The portion of the conductive wire 30 that extends into the inner side of the spool 21 from the first opening 201 and is in close contact with the first part 21A, the glue opening 31 is inserted into the second opening 202 and the glue opening 31 at least abuts against the first part 21A, and the connection port portion of the conductive wire 30 is in close contact with the second part 21B. When the user needs to use the conductive wire 30, as the user pulls the conductive wire 30 outward, when it is pulled to almost its maximum limit, the tension on the conductive wire 30 is transmitted to the adhesive port 31. The adhesive port 31 is blocked by the first part 21A, thereby reducing the tension on the connection port of the conductive wire 30 and buffering the tension at the connection port of the conductive wire 30. This avoids the conductive wire 30 being torn off due to excessive pulling force by the user, which could lead to circuit interruption or equipment failure, or damage to the shielding or insulation layer of the conductive wire 30, causing safety hazards such as leakage and short circuit, as well as disrupting the uniform distribution of the electric field and increasing the risk of breakdown.

[0041] In this embodiment, the take-up reel 20 has an overall T-shaped structure, that is, the spool 21 and the base 22 are T-shaped. The first opening 201 and the second opening 202 are located at the end of the spool 21 away from the base 22. The glue inlet 31 is adapted to the size of the second opening 202, and the glue inlet 31 is just accommodated in the second opening 202. Its two ends abut against the first part 21A and the second part 21B, respectively.

[0042] Furthermore, in order to make the glue inlet 31 fit more closely to the second opening 202, the glue inlet 31 has the same curvature as the second opening 202, or the glue inlet 31 has an arc surface on the side of the outer side 211 of the roll 21, and the curvature of the arc surface is the same as that of the second opening 202.

[0043] Specifically, the arc surfaces of the first part 21A and the second part 21B are connected through the adhesive inlet 31 to the side facing the outer surface 211 of the reel 21. The arc surfaces of the first part 21A, the adhesive inlet 31, and the second part 22B are connected to form a complete ring surface, thereby making the conductive wire 30 fit more tightly against the outer surface 211 of the reel 21 when wound. Specifically, as Figure 3 As shown, the connector 31 has a protrusion 301 that surrounds the conductive wire 30 and abuts against four walls of the first part 21A and the second part 21B respectively. The tension force on the conductive wire 30 is transmitted to the protrusion 301, which is blocked by the first part 21A. This reduces or interrupts the tendency of the conductive wire 30's connector to be pulled out, thereby reducing the tension force at the connection port of the conductive wire 30 and thus reducing damage or destruction to the conductive wire 30.

[0044] It should be noted that the adhesive opening 31 can be an integral structure with the conductive wire 30, or it can be a separate structure of the conductive wire 30, such as a sheath, which is directly sleeved on the conductive wire 30 to form the adhesive opening 31.

[0045] Specifically, when the glue opening 31 and the conductive wire 30 are separated, the glue opening 31 is provided with a first hollow structure 303, the conductive wire 30 passes through the first hollow structure 303, and the conductive wire 30 and the first hollow structure 303 are interference fit, so that the conductive wire 30 and the glue opening 31 do not need complex connecting elements, such as keys or pins, to make close contact, so that the conductive wire 30 is stuck in the glue opening 31 and is not easy to rotate freely or move relative to each other.

[0046] In the actual implementation, to ensure that the conductive wire 30 and the adhesive inlet 31 are in close contact and relatively fixed, and will not move relative to each other, the shape of the first hollow structure 303 is consistent with the shape of the conductive wire 30. For example, if the conductive wire 30 is circular, the first hollow structure 303 is circular. If the conductive wire 30 has protrusions or grooves, the inner wall of the first hollow structure 303 can be provided with corresponding grooves and protrusions for matching.

[0047] It should be noted that when the adhesive inlet 31 and the conductive wire 30 are integrally formed, the conductive wire 30 and the adhesive inlet 31 can be formed through overmolding and injection molding processes to increase the contact area between them, enhance their firmness, and further improve the protection against sudden violent pulling of the yarn reel. Furthermore, the conductive wire 30 and the adhesive inlet 31 can also be reinforced and fixed through other methods.

[0048] In a practical implementation, when the adhesive inlet 31 and the conductive wire 30 are integrally formed, the adhesive inlet 31 can be provided only on one side of the conductive wire 30. Specifically, the adhesive inlet 31 is a sheet-like structure, integrally formed on the side of the conductive wire 30 near the outer surface 211 of the spool 21. The thickness of the adhesive inlet 31 and the conductive wire 30 is the same as the thickness of the spool 21, or the thickness of the adhesive inlet 31 is independently the same as the thickness of the spool 21.

[0049] Furthermore, the first part 21A is close to the first opening 201, and the second part 21B is close to the second opening 202. The first part 21A or the second part 21B is provided with a fixing block (not shown in the figure). The fixing block is located on the inner side of the spool 21 and protrudes from the inner side of the spool. The conductive wire 30 is provided with a fixing hole (not shown in the figure) corresponding to the fixing block.

[0050] In other possible implementations, the conductive wire 30 is provided with a fixing block, and the first part 21A or the second part 21B is provided with a fixing hole corresponding to the fixing block.

[0051] Furthermore, the number of fixing blocks and fixing holes can be multiple.

[0052] Furthermore, the elastic opening 31 is elastic. When the conductive wire 30 is subjected to tension, the elastic opening 31 deforms, extending the duration of the force through elastic deformation. This buffers and counteracts the tension on the conductive wire 30, reducing the likelihood of breakage or damage due to a sudden large tension. When the tension is removed, the elastic opening 31 returns to its original shape. Specifically, the elastic opening 31 can be made of a soft material, such as a rubber band or rubber. It can also be made of a hard material, such as a spring.

[0053] Furthermore, the adhesive port 31 has good material strength, and when the conductive wire 30 is subjected to a large tensile force, it has a strong ability to withstand the stretching, compression, bending and other effects caused by the tensile force.

[0054] It should be noted that the first part 21A of the spool 21 is provided with a second hollow structure 213. After the conductive wire 30 passes through the first opening 201, it continues to pass through the second hollow structure 213, which is used to limit the conductive wire 30, prevent the conductive wire 30 from coming loose in the inner side 212 of the spool 21, and facilitate the conductive wire 30 to extend into the inner side 212 of the spool during assembly.

[0055] Furthermore, the conductive wire 30 can also be interference-fitted with the second hollow structure 213 to further buffer the tensile force on the conductive wire 30 and further fix and limit the conductive wire 30.

[0056] Furthermore, along the direction of the second hollow structure 213 toward the first opening 201, the first part 21A of the spool 21 near the first opening 201 is also provided with a transition section, that is, the second hollow structure 213 does not cover the first part 21A, and the transition section is used to adjust the direction of the conductive wire 30 passing through the first opening 201.

[0057] Furthermore, the chassis 22 is provided with a first fixing groove 220 corresponding to the second part 21B, and one end of the conductive wire 30 connection port is limited and fixed by the first fixing groove 220. Even further, the inner side of the reel 21 is also provided with a reinforcing rib 210, which is located above the first fixing groove 220 and, together with the reel 21, clamps the conductive wire 30, further limiting and fixing the conductive wire 30.

[0058] Example 2:

[0059] This embodiment is similar to Embodiment 1, such as... Figures 5-6 As shown, the spool 21 and the chassis 22 also form a T-shaped structure. The conductive wire 30 passes through the first opening 201 and enters the inner side of the spool 21. The conductive wire 30 also has an adhesive inlet 31 and is secured in the second opening 202. The difference is that the second part 21B of the spool 21, near the second opening 202, has a fixing hole 215 for accommodating the conductive wire 30. The width of the fixing hole 215 is the same as the width of the conductive wire 30, providing better securing effect. Furthermore, the bottom of the fixing hole 215 has an interface or contact point for easy electrical connection to other circuits.

[0060] Furthermore, the end of the fixing hole 215 away from the second opening 202 is closed, and the closed surface transitions gently towards the scroll 21, that is, it forms an inclined angle with the scroll 21. The fixing hole 215 is provided with an interface or conductive contact for connecting a conductive device.

[0061] Furthermore, a fixing plate 26 is provided at the end of the scroll 21 away from the chassis 22, which is used to fix and limit the components in the space inside the scroll 21, and at the same time facilitates connection with the housing 10.

[0062] Furthermore, the chassis 22 has a notch 227 near the first opening 201 for limiting and fixing the PCB board 40.

[0063] In this embodiment, as Figure 7 As shown, the reel 100 also includes a PCB board 40, a conductive structure 50, and a control mechanism 60. The PCB board 40 is fitted onto the end of the chassis 22 opposite to the reel 21 and is limited by a notch 227. The conductive structure 50 and the control mechanism 60 are mounted on the base shell 10. The control mechanism 60 controls the rotation of the take-up reel 20 and the conductive structure 50 to adjust the rotation angle, thereby controlling the length of the conductive wire 30 released, achieving arbitrary stretching and stopping. During this process, the conductive structure 50 remains electrically connected to the PCB board 40.

[0064] In addition, it should be noted that the reel 100 in this embodiment is also provided with a housing, a data interface (charging interface) and other structures, as well as a limiting mechanism for limiting the rotation of the conductive mechanism. The above structures can use existing structures in the field, and the structures that need to be protected in this application are omitted here and in the accompanying drawings. This application will not describe them in detail.

[0065] Example 3:

[0066] This embodiment differs from Embodiments 1 and 2, providing a cable reel 100, including a housing 10, a take-up reel 20, and a conductive wire 30. The difference is that in this embodiment, the spool 21 of the take-up reel 20 may not have an opening, that is, there is no first opening and second opening structure. The spool 21 is a complete toroidal surface, and the conductive wire 30 is electrically connected on the outer surface 211 of the spool 21.

[0067] In this embodiment, as Figures 8-12 As shown, the port of the conductive wire 30 is connected to the interface 29 on the outer side of the spool 21. The spool 21 is provided with a second fixing groove 208 at the connection point with the port of the conductive wire 30. The conductive wire 30 is provided with a glue inlet 31 near the port. The glue inlet 31 is located in the second fixing groove 208 and is fixed to the spool 21.

[0068] Furthermore, the adhesive port 31 is provided with a third hollow structure 502, through which the conductive wire 30 passes. The conductive wire 30 is interference-fitted with the adhesive port 31, making the conductive wire 30 in close contact with the adhesive port 31. When the conductive wire 30 is pulled to its limit, the tension on the conductive wire 30 is buffered by the adhesive port 31, reducing the tension of the conductive wire 30 at the interface 29. This prevents the conductive wire 30 from being torn off at the interface 29 due to excessive pulling force from the user, which could lead to circuit interruption or equipment failure, or damage to the shielding or insulation layer of the conductive wire 30, causing safety hazards such as leakage or short circuit, as well as disrupting the uniform distribution of the electric field and increasing the risk of breakdown.

[0069] In this embodiment, the take-up reel 20 can be a T-shaped structure or an I-shaped structure. For example... Figure 8 and Figure 9 As shown, the take-up reel 20 has an overall I-shaped structure, including an upper end face 205, a lower end face 204, and a side wall surface 206 connecting the upper end face 205 and the lower end face 204. The upper end face 205, the lower end face 204, and the side wall surface 206 enclose a cavity for accommodating the conductive wire 30. The connection between the side wall surface 206 and the upper end face 205 and the lower end face 204 is provided with a second fixing groove 208. Part of the structure of the glue outlet 31 is fixed in the second fixing groove 208, that is, the glue outlet 31 is fixed by the take-up reel 20 and the glue outlet 31 is restricted by the take-up reel 20.

[0070] Furthermore, the expansion joint 31 includes a main body 501 and a third hollow structure 502 formed by the main body 501. A portion of the main body 501 is fitted into the second fixing groove 208. The conductive wire 30 passes through the third hollow structure 502, and the conductive wire 30 is interference-fitted with the main body 501, meaning that the conductive wire 30 is in close contact with and fixed to the expansion joint 31. When the conductive wire 30 is pulled to near its limit, the expansion joint 31 is fixed by the take-up reel 20. The tension on the conductive wire 30 is transmitted to the expansion joint 31, which is then fixed by the reel 21. The tendency of the conductive wire 30 to be pulled is relieved or interrupted by the expansion joint 31, thereby reducing the tension force at the interface 29 between the conductive wire 30 and the take-up reel 20, thus reducing damage or destruction to the conductive wire 30.

[0071] Specifically, such as Figure 10 As shown, the main body 501 includes four walls: a first wall 51, a second wall 52, a third wall 53, and a fourth wall 54. The first wall 51 and the second wall 52 face each other. The second wall 52 is completely housed in the second fixing groove 208 within the take-up reel 20, and the widths of the first and second walls 51 and 52 are the same as the width of the take-up reel 20. Therefore, the width of the third hollow structure 502 is slightly smaller than the width of the conductive wire 30. The third wall 53 and the fourth wall 54 face each other, and their end portions are engaged in the second fixing groove 208. The distance between the third wall 53 and the fourth wall 54 is the same as the height of the conductive wire 30, meaning the height of the third hollow structure 502 is the same as the thickness of the conductive wire 30. Since the width of the conductive wire 30 is also the same as the width of the take-up reel 20... When the conductive wire 30 passes through the third hollow structure 502 formed by the first wall surface 51, the second wall surface 52, the third wall surface 53, and the fourth wall surface 54, it is interference-fitted with the main body 501, thus fixing the conductive wire 30 to the glue opening 31. When the conductive wire 30 is almost stretched to its limit, as the conductive wire 30 is pulled, the second wall surface 52 is blocked by the fixing groove 208. The fixing groove 208 acts as a buffer for the glue opening 31, interrupting or reducing the pulling tendency of the conductive wire 30, so that the conductive wire 30 from the glue opening 31 to the interface 29 is not pulled outward, thereby reducing the tension of the conductive wire 30 at the interface 29 and reducing damage to the conductive wire 30 at the interface 29.

[0072] Furthermore, the height of the second fixing groove 208 is the same as the thickness of the second wall surface 52, so that the inner wall surface of the second wall surface 52 is flush with the side wall surface 206 of the take-up reel 20, so that the conductive wire 30 can remain flat when it is wound in the take-up reel 20.

[0073] Furthermore, to ensure a better fit between the adhesive inlet 31 and the take-up reel 20, the adhesive inlet 31 has the same curvature as the take-up reel 20. Additionally, to guarantee tight contact between the conductive wire 30 and the adhesive inlet 31, the shape of the third hollow structure 502 is consistent with the shape of the conductive wire 30. For example, if the conductive wire 30 is circular, the third hollow structure 502 will also be circular. If the conductive wire 30 has protrusions or grooves, the third hollow structure 502 will have corresponding grooves or protrusions to match them.

[0074] Furthermore, such as Figure 10 As shown, if the rubber inlet 31 is made of a soft material, the second wall surface 52 of the rubber inlet 31 is provided with a through hole 503. Through the through hole 503, the internal structure of the rubber inlet 31 is more likely to deform when subjected to tension, thereby enhancing the buffering effect.

[0075] Furthermore, since the glue outlet 31 is close to the interface 29, and the second fixing groove 208 restricts the glue outlet 31, the conductive wire 30 between the glue outlet 31 and the interface 29 cannot be pulled out. If the glue outlet 31 is too far from the interface 29, the actual maximum length of the conductive wire 30 pulled out will be shortened. Therefore, the glue outlet 31 should be as close as possible to the interface 29.

[0076] Example 4:

[0077] This embodiment is similar in structure to the cable reel 100 in Embodiment 3, as shown in the attached figure. Figure 13 As shown, in this embodiment, the adhesive inlet 31 is a sheet-like structure. The adhesive inlet 31 and the side wall surface 206 of the take-up reel 20 form a fourth hollow structure (not shown). The conductive wire 30 passes through the fourth hollow structure and is subjected to pressure from the adhesive inlet 31 towards the take-up reel 20, resulting in close contact between the conductive wire 30 and the adhesive inlet 31. Specifically, the adhesive inlet 31 is parallel to the side wall surface 206 of the take-up reel 20. The top and bottom ends of the adhesive inlet 31 are respectively engaged with the upper end surface 205 and the lower end surface 204 of the take-up reel 20. The thickness of the adhesive inlet 31 is greater than that of the conductive wire 30, which squeezes the conductive wire 30 towards the take-up reel 20, making it difficult for the conductive wire 30 to move within the fourth hollow structure.

[0078] In this embodiment, the surface of the adhesive inlet 31 facing the take-up reel 20 has a higher roughness. When the conductive wire 30 is subjected to tension, friction is generated between the adhesive inlet 31 and the conductive wire 30, thereby transmitting the tension of the conductive wire 30 to the adhesive inlet 31. The adhesive inlet 31 extends the duration of the force by undergoing elastic deformation, thereby buffering and offsetting the tension on the conductive wire 30, and reducing the possibility of the conductive wire 30 breaking or being damaged due to a large instantaneous tension.

[0079] Furthermore, the adhesive port 31 can be provided with microstructures or protrusions to increase roughness and increase the friction between the adhesive port 31 and the conductive wire 30.

[0080] In this embodiment, the conductive wire 30 can also be fixed to the adhesive inlet 31, such as by using adhesive to keep the conductive wire 30 and the adhesive inlet 31 fixed. Alternatively, the adhesive inlet 31 facing the take-up reel 20 can be fixed by providing corresponding grooves and protrusions, so that when the conductive wire 30 is subjected to tension at the adhesive inlet 31, the conductive wire 30 is bound and fixed by the adhesive inlet 31, and the tension on the conductive wire 30 is transmitted to the adhesive inlet 31, thereby reducing the tension of the conductive wire 30 at the interface 29.

[0081] It should be noted that the curvature of the rubber inlet 31 is consistent with that of the side wall of the take-up reel 20. The hollow structure enclosed by the rubber inlet 31 and the take-up reel 20 can be rectangular or curved.

[0082] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
