Description

Technical Field

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

[0002] In the current field of electronic device accessories, data cables, as key components connecting electronic devices to power sources or other devices, have extremely wide applications, covering various aspects of daily life, office work, and travel. However, existing data cables on the market cannot achieve effective extension and deformation.

[0003] As users increasingly demand greater flexibility and portability in their electronic devices, the drawbacks of existing data cables—their inability to extend or deform—are becoming more pronounced, making it difficult to meet diverse usage needs. For example, when users are far from power outlets, insufficient cable length prevents them from charging or transferring data smoothly, forcing them to find extension cables or adjust their location, severely impacting ease of use. In confined spaces, excessively long cables become cluttered and take up space, potentially causing damage and shortening their lifespan due to tangling and pulling.

[0004] Therefore, there is an urgent need for a data cable that can extend and deform to meet diverse usage needs. Utility Model Content

[0010] In one embodiment of the present invention, the core wire includes a conductor wire and an insulating elastic layer that wraps the conductor wire, wherein the insulating elastic layer of the stretchable portion is a wavy bending structure or a zigzag bending structure extending along the length direction.

[0011] In one embodiment of this utility model, the outer sheath has a flat structure, and the number of core wires is multiple, with the multiple core wires arranged along the width direction of the data line.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] See Figure 1 This utility model embodiment provides a data cable 10, which may include, for example, a connecting wire 100 and two connectors 200. The two connectors 200 are located at both ends of the connecting wire 100, and the connectors 200 are electrically connected to the connecting wire 100.

[0033] See Figure 2 The connecting cable 100 may include a core wire 110 and an outer sheath 120, with the outer sheath 120 wrapping around the core wire 110. The core wire 110 includes a retractable portion arranged along the length direction of the data cable 10, which can extend and retract along this length direction. Similarly, the outer sheath 120 can also extend and retract along the length direction, and the outer sheath is made of an elastic material. Specifically, the outer sheath 120 may be made of elastic materials such as rubber or silicone, allowing it to be stretched under external force and return to its original shape after the external force is removed. For example, when a user is far from a power outlet and needs to use a longer data cable for charging, the data cable 10 can be stretched to meet the long-distance usage requirements; when using the data cable 10 in a small space, the data cable 10 returns to its original state for easy use. Therefore, the data cable 10 provided in this embodiment is stretchable compared to existing basic-length data cables, thus meeting long-distance requirements, and is shorter than the length of existing long data cables, making it easier to store. The data cable 10 provided in this embodiment sets the connecting wire 100 as a core wire 110 and an outer sheath 120 that wraps the core wire 110. By setting the core wire 110 with a retractable part and setting the outer sheath 120 as an elastic material that can stretch along the length direction, the data cable 10 can be stretched to meet the usage requirements of different lengths and meet diverse usage scenarios.

[0034] In this embodiment, the elastic deformation of the outer sheath 120 is greater than or equal to the elastic deformation of the core wire 110, and the maximum tensile length of the outer sheath 120 is greater than or equal to the maximum tensile length of the core wire 110. If the elastic deformation of the outer sheath 120 is less than the elastic deformation of the core wire 110, the maximum tensile length of the data line 10 will be less than the preset tensile length. By ensuring that the elastic deformation of the outer sheath 120 is greater than or equal to the elastic deformation of the core wire 110, the tensile length of the data line 10 can be guaranteed to reach the preset tensile length, and the difficulty of tensile operation can be reduced, making it easier for users to perform the tensile operation.

[0035] like Figure 2 and Figure 3 As shown, in one embodiment of this invention, the telescopic portion is a wavy or zigzag curved structure, comprising a plurality of alternately connected raised curved sections 1101 and recessed curved sections 1102. The telescopic portion of the core wire 110 extends in a wavy or zigzag shape along its length. Under external force, the core wire 110 is stretched, causing deformation of the telescopic portion. Theoretically, in extreme cases, the telescopic portion can be stretched from a wavy or zigzag shape to a straight shape. See also... Figure 5 and Figure 6 , Figure 5 and Figure 6 This diagram illustrates the data cable 10 after it has been stretched. The core wire 110 and outer sheath 120 are stretched under external force, allowing the data cable 10 to be elongated. Furthermore, after the external force is removed, both the core wire 110 and the outer sheath 120 return to their original shape. The stretching and contraction of the data cable 10 is achieved through the wavy or zigzag bending structure of the core wire 110 and the elastic material of the outer sheath 120.

[0036] See Figure 4 and Figure 7 The retractable section includes multiple consecutive raised curved sections 1101 and recessed curved sections 1102, which are adjacent to each other. The raised curved section 1101 has a raised apex. When the data line 10 is in a normal state, there is a first gap W1 between two adjacent raised apexes of the core wire 110. When the data line 10 is in a stretched state, there is a second gap W2 between two adjacent raised apexes of the core wire 110, and the second gap W2 is greater than the first gap W1. In the stretched state, because the core wire 110 is stretched, the second gap W2 becomes greater than the first gap W1. In extreme cases, the core wire 110 can be stretched into a straight line. The length of the stretched extension (increase) is equal to the outer circumference of the bend (wave shape) multiplied by the number of deformations (wave count). That is, the larger the bending radius, the longer the stretched length. The bending radius of the wave can be set as needed.

[0037] See Figure 8 and Figure 9The core wire 110 may include, for example, a conductor wire 113 and an insulating elastic layer 114. The insulating elastic layer 114 wraps around the conductor wire 113. The insulating elastic layer 114 of the stretchable portion has a wavy or zigzag bend structure extending along the length direction. The conductor wire 113 may be, for example, a copper conductor, and the insulating elastic layer 114 may be, for example, made of PP (Polypropylene), FEP (Fluorinated Ethylene Propylene), or XLPE (Cross-linked Polyethylene). The insulating elastic layer 114 can be formed by high-temperature extrusion to wrap around the conductor wire 113. The insulating elastic layer 114 is formed by high-temperature extrusion to form a wavy or zigzag bend structure and wraps around the conductor wire 113, so that the core wire 110 as a whole presents a wavy extension and has deformation capability and a certain degree of stretching characteristics.

[0038] See also Figure 1 and Figure 5 The outer sheath 120 has a flat structure, which makes the connecting wire 100 flat as well. The flat structure of the connecting wire 100 makes it easier to store, reducing storage space. Furthermore, the outer sheath 120's wrapping of the core wire 110 enhances its protection. See further... Figure 4 There are multiple core wires 110, which are arranged along the width of the data line 10. The thickness of the outer sheath 120 only needs to cover the diameter of a single core wire 110. The width of the outer sheath 120 covers multiple core wires 110, thus making the outer sheath 120 have a flat structure.

[0039] In one embodiment of this invention, the multiple core wires 110 include signal lines 111 and power lines 112, which are arranged along the width of the data line 10. The signal lines 111 include D+, CC, and D- signal lines, and the power lines 112 include a positive power line and a negative power line. During the communication process of the charging protocol handshake between the device to be charged and the charger via the data line 10, the D+, CC, and D- signal lines are used to transmit corresponding charging protocol handshake signals. In some embodiments of this invention, the raised bends 1101 on the signal lines 111 and 1102 on the power lines 112 are staggered, and the recessed bends 1102 on the signal lines 111 and 1102 on the power lines 112 are also staggered. In other embodiments of this invention, the raised bends 1101 on the signal lines 111 and 1102 on the power lines 112 are correspondingly arranged. For example, the protruding bend 1101 of signal line 111 corresponds to the recessed bend 1102 of power line 112, and the recessed bend 1102 of signal line 111 corresponds to the protruding bend 1101 of power line 112. Of course, this embodiment is not limited to this. This arrangement makes it easy to distinguish between signal line 111 and power line 112.

[0040] In one embodiment of this example, the outer sheath 120 may be made of elastic yarn woven into a mesh and wound with the core wire 110 to form a data cable. In another embodiment of this example, the outer sheath 120 may have a hollow space formed inside, and the core wire 110 is housed in the hollow space. The outer sheath 120 may be integrally formed on the outside of the core wire 110, or the outer sheath 120 may be an upper outer sheath and a lower outer sheath separated from each other, with the core wire 110 located between the upper and lower outer sheaths. Of course, this embodiment is not limited to this. The outer sheath 120 may have a housing space inside, and the core wire 110 is disposed in the housing space. In some embodiments of this example, the housing space includes a housing through hole, and multiple core wires 110 are located in one housing through hole. In other embodiments of this example, the housing space includes multiple housing through holes, and multiple core wires 110 are located one-to-one in multiple housing through holes.

[0041] In one embodiment of this invention, the core wire 110 is fixedly connected to the outer sheath 120, for example, the core wire 110 is pasted inside the outer sheath 120, although this embodiment is not limited to this. By fixing the core wire 110 to the outer sheath 120, the outer sheath 120 and the core wire 110 can deform together when stretched, distributing external force to the outer sheath 120 and the core wire 110 as a whole, preventing a single core wire 110 from breaking due to excessive local stress, and preventing multiple core wires 110 from tangling, being squeezed, etc., reducing signal interference caused by internal structural disorder. In another embodiment of this invention, the core wire 110 is movably disposed inside the outer sheath 120, allowing it to freely adjust its posture when subjected to external force, reducing the forced constraint on the core wire 110 due to the deformation of the outer sheath 120, making the data cable 10 more flexible overall; when the data cable 10 is stretched, the unfixed core wire 110 can naturally stretch with the elongation of the outer sheath 120, reducing the probability of the core wire being overstretched and improving the overall tensile tolerance.

[0042] See also Figure 2 The connector 200 includes a connection terminal 210 and a circuit board 220 electrically connected to the connection terminal 210. The end of the connecting cable 100 is electrically connected to the circuit board 220. The data cable 10 may also include two connectors 300, which are fixedly connected between the connecting cable 100 and the connector 200, and are sleeved on the end of the connecting cable 100 and the circuit board 220. The connectors 300 may, for example, be integrally formed on the end of the connecting cable 100 and the circuit board 220, or may, for example, be adhered to the end of the connecting cable 100 and the circuit board 220. The connectors 300 can improve the connection stability between the connecting cable 100 and the connector 200, and protect the connection point between the connecting cable 100 and the connector 200, preventing the core wire 110 from detaching from the connector 200 due to external force during stretching, thereby increasing service life. In some embodiments of this example, metal buckles may be provided at both ends of the connector 300, and the metal buckles are fixed to the connecting wire 100 and the connector 200 respectively, thereby further improving the connection stability between the connecting wire 100 and the connector 200.
