Description

Technical Field

[0001] This application relates to the field of connecting wire technology, and in particular to a connecting wire with heat dissipation function. Background Technology

[0002] Currently, many connector cables on the market, including data cables and charging cables, commonly experience severe overheating at their plug interfaces during use. This not only affects the data cable's transmission efficiency and lifespan but also poses potential safety hazards, becoming a major concern for consumers when selecting and using data cables.

[0003] Therefore, while ensuring the stable function of the connecting cable, how to effectively solve the problem of overheating at the plug interface has become an urgent issue to be addressed. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a connecting cable with heat dissipation function, which can not only ensure functional stability, but also solve the problem of the interface easily overheating during use.

[0005] To achieve the above objectives, this application provides a connecting cable with heat dissipation function, comprising: a cable body, a first interface assembly, a fixing member, and a heat dissipation member. The cable body includes a conductive wire and a sleeve wrapping the conductive wire. The first interface assembly is connected to the conductive wire. One end of the fixing member is connected to the first interface assembly, and the other end of the fixing member is connected to the sleeve. The conductive wire is embedded in the fixing member. The heat dissipation member includes a housing and a heat dissipation layer. A heat dissipation cavity is formed between the inner surface of the housing and the heat dissipation layer. The first interface assembly and the fixing member are disposed within the heat dissipation layer, and a flowing liquid is disposed within the heat dissipation cavity.

[0006] According to the embodiments of this utility model, a connecting cable with heat dissipation function has at least the following beneficial effects: First, one end of the fixing member is connected to the first interface assembly, and the other end of the fixing member is connected to the wire sleeve. The conductive wire extends from the wire sleeve and passes through the internal cavity of the fixing member to connect to the first interface assembly. Under the fixing action of the fixing member, the connection between the conductive wire and the first interface assembly is more stable and less likely to break under external force, thus enabling more stable power transmission or data transmission during use. Second, the heat dissipation cavity formed between the inner surface of the housing and the heat dissipation layer serves as a space for heat exchange, which helps in the transfer and dissipation of heat. This is particularly beneficial when the connecting cable is used for charging or data transmission in electronic devices. During the process, heat is generated inside the first interface component, especially in the area near the connection between the first interface component and the fixing member, where the temperature is usually relatively high. By placing the first interface component and the fixing member inside the heat dissipation layer, heat can be effectively transferred from the heat dissipation layer to the heat dissipation cavity. Furthermore, a flowing liquid is placed inside the heat dissipation cavity. The flowing liquid has a high specific heat capacity and can absorb a large amount of heat, which is then transferred to the external environment through the outer surface of the shell. This quickly reduces the temperature of the first interface component to maintain the stability of the connection cable. In addition, the flowing liquid inside the heat dissipation cavity not only improves the heat dissipation effect but also serves a decorative purpose, making the connection cable more aesthetically pleasing.

[0007] In some embodiments, the housing and heat dissipation layer of the heat sink are both made of transparent material.

[0008] In some embodiments, the flowing liquid is a transparent material; the flowing liquid is a translucent material; or, the flowing liquid is an opaque material; or, the flowing liquid is a fluorescent material.

[0009] In some embodiments, an annular seal is further included, the front end of the heat dissipation cavity is sealed, and the rear end of the heat dissipation cavity is provided with an opening, the annular seal being used to seal the opening of the heat dissipation cavity.

[0010] In some embodiments, the annular seal includes a first ring body and a second ring body, the first ring body being connected to the second ring body, and the second ring body being used to block the opening of the heat dissipation cavity.

[0011] In some embodiments, a step is provided on the inner surface of the housing, the step being used to limit the first ring body.

[0012] In some embodiments, the first interface component includes a first interface and a chip fixedly connected to the first interface, the first interface being used to connect to an electrical device, and the chip being connected to a conductive wire of the line body.

[0013] In some embodiments, the fixing member includes a first fixing part and a second fixing part connected to the first fixing part. The first fixing part is provided with a first receiving cavity, and the wire sleeve is built into the first receiving cavity. The second fixing part is provided with a second receiving cavity, and the chip and the conductive wire are both built into the second receiving cavity.

[0026] Currently, many connector cables on the market, including data cables and charging cables, commonly experience severe overheating at their plug interfaces during use. This not only affects the data cable's transmission efficiency and lifespan but also poses potential safety hazards, becoming a major concern for consumers when selecting and using data cables.

[0027] Based on this, this utility model embodiment provides a connecting cable with heat dissipation function, which can not only ensure functional stability, but also solve the problem of interface overheating during use.

[0028] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0029] Reference Figures 1 to 3 This utility model provides a connecting wire with heat dissipation function, including: a wire body 100, a first interface component 200, a fixing member 300, and a heat dissipation component 400. The wire body 100 includes a conductive wire 120 and a wire sleeve 110 that wraps the conductive wire 120. The first interface component 200 is connected to the conductive wire 120. One end of the fixing member 300 is connected to the first interface component 200, and the other end of the fixing member 300 is connected to the wire sleeve 110. The conductive wire 120 is built into the fixing member 300. The heat dissipation component 400 includes a housing 410 and a heat dissipation layer 420. A heat dissipation cavity 430 is formed between the inner surface of the housing 410 and the heat dissipation layer 420. The first interface component 200 and the fixing member 300 are disposed in the heat dissipation layer 420, and a flowing liquid is disposed in the heat dissipation cavity 430.

[0030] According to an embodiment of this utility model, a connecting cable with heat dissipation function is provided. First, one end of the fixing member 300 is connected to the first interface assembly 200, and the other end of the fixing member 300 is connected to the wire sleeve 110. The conductive wire 120 extends from the wire sleeve 110 and passes through the internal cavity of the fixing member 300 to connect to the first interface assembly 200. Under the fixing action of the fixing member 300, the connection between the conductive wire 120 and the first interface assembly 200 is more stable and less likely to break under external force, thus enabling more stable power transmission or data transmission during use. Second, the heat dissipation cavity 430 formed between the inner surface of the housing 410 and the heat dissipation layer 420 serves as a space for heat exchange, which helps in the transfer and dissipation of heat. During the process of using the connecting cable for charging or data transmission of electronic devices, Heat is generated inside the first interface component 200, especially in the area near the connection between the first interface component 200 and the fixing member 300, where the temperature is usually relatively high. By placing the first interface component 200 and the fixing member 300 within the heat dissipation layer 420, heat can be effectively transferred from the heat dissipation layer 420 to the heat dissipation cavity 430. Furthermore, a flowing liquid with a high specific heat capacity is provided in the heat dissipation cavity 430, which can absorb a large amount of heat and then transfer it to the external environment through the outer surface of the housing 410. This quickly reduces the temperature of the first interface component 200 to maintain the stability of the connection cable. In addition, the flowing liquid in the heat dissipation cavity 430 not only improves the heat dissipation effect but also serves a decorative purpose, making the connection cable more aesthetically pleasing.

[0031] It should be noted that a ring-shaped heat dissipation cavity 430 is formed between the housing 410 and the heat dissipation layer 420 of the heat sink 400. The ring-shaped heat dissipation cavity 430 increases the contact area for heat exchange with the first interface assembly 200 and the fixing member 300, thereby further improving the heat dissipation effect.

[0032] Preferably, the housing 410 and heat dissipation layer 420 of the heat sink 400 are both made of silicone material. The housing 410 and heat dissipation layer 420 of the heat sink 400 have good flexibility. The heat dissipation layer 420 can adapt to the shape and size changes of the first interface assembly 200 and the fixing member 300, ensuring a tight fit with the first interface assembly 200 and the fixing member 300. This allows for better transfer of heat generated inside the first interface assembly 200 to the heat dissipation cavity 430, improving the heat dissipation effect. In addition, the annular structure of the heat sink 400 has good shock absorption performance, which can absorb and disperse vibrations, protecting the first interface assembly 200 and the fixing member 300 located inside the heat sink 400 from vibration damage, thereby extending the service life of the connecting wire.

[0033] It should be noted that the flowing liquid is composed of a liquid substance with thermal conductivity, which can help the heat sink 400 to quickly absorb heat and improve the heat dissipation effect.

[0034] Understandably, the heat sink 400, fitted onto the first interface assembly 200 and the fixing member 300, not only serves to dissipate heat but also protects the electrical components within the first interface assembly 200 from external environmental interference and damage. For example, it prevents dust, moisture, and other impurities from entering the first interface assembly 200, thereby extending the equipment's lifespan. Furthermore, the heat sink 400 further strengthens the connection between the fixing member 300 and the first interface assembly 200, ensuring the stability and reliability of the equipment.

[0035] Preferably, the heat dissipation layer 420 can be made of a material with high thermal conductivity to improve heat dissipation efficiency.

[0036] In some embodiments, the housing 410 and the heat dissipation layer 420 of the heat sink 400 are both made of transparent material.

[0037] Understandably, the transparent housing 410 and heat dissipation layer 420 make the internal flowing liquid clearly visible, and this dynamic visual effect provides users with a unique visual experience.

[0038] In some embodiments, the flowing liquid is a transparent material; the flowing liquid is a translucent material; or, the flowing liquid is an opaque material; or, the flowing liquid is a fluorescent material.

[0039] Understandably, different pigments can be added to the flowing liquid in the heat dissipation cavity 430 to create a semi-transparent or opaque material. During the heat dissipation process, the flowing liquid can exhibit different colors or light and shadow changes, increasing the product's interest and visual appeal. If the flowing liquid is fluorescent, it can glow in the dark, not only providing users with a unique visual experience but also helping them quickly locate connection cables in the dark, thus enhancing the user experience.

[0040] Preferably, the flowing liquid can be mineral oil, silicone oil, or fluorinated liquid; the material of the flowing liquid is not limited in this regard.

[0041] Preferably, the heat sink 400 is detachably mounted on the first interface assembly 200 and the fixing member 300. By adding different colored liquids to the heat sink cavity 430, heat sinks 400 of different colors can be formed. Users can replace the heat sinks 400 of different colors with their own preferences and mount them on the first interface assembly 200 and the fixing member 300 to improve the user experience.

[0042] In some embodiments, refer to Figure 1 , Figure 2 It also includes an annular seal 500, a front end seal for the heat dissipation cavity 430, and an opening at the rear end of the heat dissipation cavity 430. The annular seal 500 is used to seal the opening of the heat dissipation cavity 430.

[0043] Preferably, the annular seal 500 is detachably disposed at the opening of the sealed heat dissipation cavity 430, which facilitates the user to replace the flowing liquid, for example, injecting flowing liquid of different colors into the heat dissipation cavity 430, thereby improving the user experience.

[0044] In some embodiments, refer to Figure 1 , Figure 2 The annular seal 500 includes a first ring body 510 and a second ring body 520. The first ring body 510 is connected to the second ring body 520, and the second ring body 520 is used to block the opening of the heat dissipation cavity 430.

[0045] It should be noted that the diameter of the first ring body 510 is larger than the diameter of the second ring body 520, and the rear end of the housing 410 is used to limit the first ring body 510.

[0046] Preferably, the second ring 520 is adapted to the opening of the heat dissipation cavity 430, which can better seal the flowing liquid in the heat dissipation cavity 430 and prevent leakage. In addition, the rear end of the housing 410 provides a limiting effect on the first ring 510, which can prevent the first ring 510 from collapsing or falling off under pressure or external force, ensuring that the annular seal 500 always stays in the correct position and improving stability.

[0047] Preferably, the first ring body 510 is made of plastic material, but no further restrictions are imposed here.

[0048] Preferably, the second ring 520 is made of silicone material by liquid injection molding and is firmly bonded to the first ring 510 as a whole; however, no further limitations are imposed here.

[0049] Furthermore, adhesive is applied to seal the joint between the first ring body 510 and the housing 410, for example, by applying UV-curable adhesive to ensure that the liquid flowing inside the heat dissipation cavity 430 does not leak out.

[0050] In some embodiments, refer to Figure 4 , Figure 5 A step 411 is provided on the inner surface of the housing 410, which is used to limit the first ring body 510.

[0051] It should be noted that the diameter of the first ring 510 is larger than that of the second ring 520. The second ring 520 is adapted to the opening of the heat dissipation cavity 430, which can better seal the flowing liquid inside the heat dissipation cavity 430 and prevent leakage. In addition, the step 411 limits the first ring 510, so that the first ring 510 can be precisely fixed on the outside of the step 411, preventing the first ring 510 from collapsing into the heat dissipation cavity 430 under pressure or external force, which helps to improve the sealing effect of the second ring 520. Furthermore, the step 411 provides a clear installation position for the first ring 510, simplifying the installation process and reducing the difficulty of operation.

[0052] Furthermore, apply adhesive to seal the joint between the first ring 510 and the step 411, for example, apply UV-curable adhesive to ensure that the liquid flowing inside the heat dissipation cavity 430 does not leak out.

[0053] In some embodiments, refer to Figure 1 The first interface component 200 includes a first interface 210 and a chip 220 fixedly connected to the first interface 210. The first interface 210 is used to connect electrical equipment, and the chip 220 is connected to the conductive wire 120 of the line body 100.

[0054] Preferably, the structure of the heat dissipation cavity 430 is annular, the radial thickness of the heat dissipation cavity 430 is 0.5 mm, and the axial length of the heat dissipation cavity 430 is 19 mm. Here, the radial thickness and axial length of the heat dissipation cavity 430 are not limited too much.

[0055] Preferably, the structure of the heat dissipation layer 420 is annular, and the maximum radial length of the heat dissipation layer 420 is 9 mm. Here, the maximum radial length of the heat dissipation layer 420 is not limited too much.

[0056] Preferably, the axial length of the conductive wire 120 exposed outside the wire sleeve 110 is 8.5 mm. Here, the axial length of the conductive wire 120 exposed outside the wire sleeve 110 is not limited too much.

[0057] Preferably, the axial length of chip 220 is 8.5mm, but the axial length of chip 220 is not limited in too much.

[0058] Preferably, the ratio between the maximum radial length of the heat dissipation layer 420 and the radial thickness of the heat dissipation cavity 430 is 18:1. Here, the ratio between the maximum radial length of the heat dissipation layer 420 and the radial thickness of the heat dissipation cavity 430 is not limited too much.

[0059] Preferably, the ratio between the axial length of the heat dissipation cavity 430 and the axial length of the conductive wire 120 exposed outside the wire sleeve 110 is 2.2:1. Here, we will not impose too much limitation on the ratio between the axial length of the heat dissipation cavity 430 and the axial length of the conductive wire 120 exposed outside the wire sleeve 110.

[0060] Preferably, the ratio between the axial length of the heat dissipation cavity 430 and the axial length of the chip 220 is 2.2:1. Here, we will not impose too many restrictions on the ratio between the axial length of the heat dissipation cavity 430 and the axial length of the chip 220.

[0061] In this embodiment, preferably, the heat sink 400 is detachably sleeved on the first interface assembly 200 and the fixing member 300. The first interface 210 can be of type USB Type-C or USB Type-A, etc., and the power device can be an electronic product such as a mobile phone or tablet. In addition, after the heat sink 400 is installed, it will not affect the connection between the first interface 210 and the power device.

[0062] It should be noted that one end of the fastener 300 is connected to the chip 220, and the conductive wire 120 extends out from the wire sleeve 110 and passes through the internal cavity of the fastener 300 before connecting to the chip 220 of the first interface assembly 200.

[0063] In some embodiments, refer to Figure 2 The fixing member 300 includes a first fixing part 310 and a second fixing part 320 connected to the first fixing part 310. The first fixing part 310 is provided with a first receiving cavity, and the wire sleeve 110 is built into the first receiving cavity. The second fixing part 320 is provided with a second receiving cavity, and the chip 220 and the conductive wire 120 are both built into the second receiving cavity.

[0064] It is understandable that by embedding both the chip 220 and the conductive line 120 within the second receiving cavity, the second fixing part 320 can play a certain buffering and protective role, reducing the impact of external impacts and vibrations on the connection stability between the conductive line 120 and the chip 220.

[0065] In some embodiments, the second fixing part 320 is made of a thermally conductive material.

[0066] It is understandable that if the second fixing part 320 is made of thermally conductive material, the second fixing part 320 can not only play a certain buffering and protective role, reducing the impact of external impact and vibration on the connection stability between the conductive wire 120 and the chip 220, but also quickly transfer the heat generated in the chip 220 to the heat sink 400, thereby enhancing the heat dissipation effect.

[0067] In some embodiments, refer to Figure 1 , Figure 2 The heat sink 400 has an annular boss 440 at the front end of the housing 410, which is sleeved on the first interface 210, and the heat dissipation layer 420 is sleeved on the second fixing part 320.

[0068] It should be noted that the annular boss 440 fits into the first interface 210, which can effectively prevent the heat dissipation cavity 430 from falling off under the action of external force after it is sleeved on the second fixing part 320.

[0069] Preferably, a plurality of evenly spaced first protrusions are provided on the inner side of the annular boss 440. At the same time, a corresponding number of evenly spaced second protrusions are also arranged in the area where the first interface 210 contacts the annular boss 440. The first and second protrusions are arranged in an alternating manner to cooperate and support each other. On the one hand, this helps to install and position the annular boss 440 on the first interface 210. On the other hand, it can significantly enhance the stability of the heat dissipation cavity 430 after it is fitted onto the second fixing part 320, and effectively prevent it from falling off under external force.

[0070] Furthermore, the first protrusion structure inside the annular boss 440 is set in an inclined shape, and the second protrusion structure in the first interface 210 is also set in an inclined shape accordingly. The first protrusion structure and the second protrusion structure cooperate and support each other, which can further significantly enhance the stability of the heat dissipation cavity 430 after it is sleeved on the second fixing part 320, and more effectively prevent it from falling off under the action of external force.

[0071] It should be noted that during use, heat can easily accumulate in the chip 220. Constructing both the chip 220 and the conductive wire 120 within the second receiving cavity of the second fixing part 320 facilitates heat transfer to the second fixing part 320. Furthermore, placing the heat dissipation layer 420 on the second fixing part 320 helps transfer the accumulated heat in the second fixing part 320 to the heat dissipation cavity 430, allowing the flowing liquid inside the heat dissipation cavity 430 to effectively exchange heat with the second fixing part 320, thereby rapidly reducing the temperature of the chip 220 and preventing damage due to overheating. Additionally, the heat dissipation cavity 430 formed between the housing 410 and the heat dissipation layer 420 also acts as a buffer and protector, reducing the impact of external impacts and vibrations on the connection stability between the conductive wire 120 and the chip 220.

[0072] Preferably, a gap is reserved between the heat dissipation layer 420 and the second fixing part 320, which can effectively prevent the expansion of the flowing liquid in the heat dissipation cavity 430 due to the influence of external factors, thereby causing the internal chip 220 to be squeezed. For example, in winter, the flowing liquid expands due to solidification or in summer, the volume of the flowing liquid changes due to evaporation, which can ensure that the internal chip 220 will not be squeezed unnecessarily, thereby ensuring the stable operation of the connecting wire.

[0073] Preferably, the radial thickness of the gap is 0.1 mm, but the radial thickness of the gap is not limited in too much.

[0074] Preferably, the thickness of the first protrusion structure inside the annular boss 440 is 0.1 mm. Here, the thickness of the first protrusion structure inside the annular boss 440 is not limited too much.

[0075] Understandably, with the cooperation and support between the first protrusion structure inside the annular boss 440 and the second protrusion structure on the first interface 210, even if there is a gap between the heat dissipation layer 420 and the second fixing part 320, the heat dissipation layer 420 can be stably fitted onto the second fixing part 320, effectively preventing it from falling off under external force.

[0076] In some embodiments, refer to Figure 1 , Figure 2 , Figure 3 The first fixing part 310 includes a first boss 311 and an annular sleeve 312. One end of the first boss 311 is connected to the second fixing part 320, and the other end of the first boss 311 is connected to the annular sleeve 312. A receiving cavity is provided in both the first boss 311 and the annular sleeve 312. The receiving cavity provided in the first boss 311 and the receiving cavity provided in the annular sleeve 312 are connected to form a first receiving cavity. The wire sleeve 110 is built into the first receiving cavity.

[0077] It should be noted that the first boss 311 is used to limit the heat sink 400. The first boss 311 provides a clear installation position for the heat sink 400, ensuring that the heat sink layer 420 is accurately fitted onto the second fixing part 320.

[0078] It should be noted that when the heat dissipation layer 420 is fitted onto the second fixing part 320, the outer side of the second fixing part 320 will be wrapped by the heat dissipation cavity 430 formed between the housing 410 and the heat dissipation layer 420. Furthermore, from an overall perspective, the rear end of the housing 410 of the heat dissipation component 400 is tightly fitted with one end of the first protrusion 311, and the outer surface of the housing 410 of the heat dissipation component 400 is flush with the upper surface of the first protrusion 311, forming a smooth transition and reducing gaps. This not only reduces the entry of dust, moisture or other contaminants into the second fixing part 320, but also improves the overall cleanliness and aesthetics.

[0079] In some embodiments, the annular seal 500 includes a first ring body 510 and a second ring body 520, the first ring body 510 and the second ring body 520 are connected, the second ring body 520 is used to block the opening of the heat dissipation cavity 430, a step 411 is provided on the inner surface of the housing 410, the step 411 is used to limit the first ring body 510, the front end of the housing 410 of the heat dissipation component 400 is provided with an annular boss 440, the annular boss 440 is sleeved on the first interface 210, the heat dissipation layer 420 is sleeved on the second fixing part 320, the first fixing part 310 includes a first boss 311 and an annular sleeve 312, one end of the first boss 311 is connected to the second fixing part 320, the other end of the first boss 311 is connected to the annular sleeve 312, a receiving body is provided in both the first boss 311 and the annular sleeve 312, the receiving body in the first boss 311 and the receiving body in the annular sleeve 312 are connected to form a first receiving body, and the wire sleeve 110 is built into the first receiving cavity.

[0080] It should be noted that, referring to Figure 5 After the annular seal 500 is used to seal the opening of the heat dissipation cavity 430, a groove 600 is formed between the second ring 520, the inner surface of the housing 410, and the heat dissipation layer 420. Glue is injected into the groove 600, which not only seals the joint between the first ring 510 and the housing 410, ensuring that the liquid flowing in the heat dissipation cavity 430 will not flow out and cause leakage, but also makes the joint between the heat dissipation component 400 and one end of the first boss 311 more tightly connected, ensuring that the heat dissipation layer 420 can be stably fitted onto the second fixing part 320, thereby enabling the liquid flowing inside the heat dissipation cavity 430 to exchange heat with the second fixing part 320 stably and effectively, so as to maintain a stable heat dissipation effect.

[0081] Understandably, injecting glue into the groove 600 fills the gap between the heat sink 400 and the first boss 311, effectively preventing dust, moisture or other contaminants from entering the second fixing part 320.

[0082] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
