Description

Technical Field

[0001] This utility model relates to the field of household wire harness technology, and in particular to a household wire harness with a heat dissipation sleeve. Background Technology

[0002] A wire harness is a component consisting of a bundle of wires, cables, or optical fibers bundled together for transmitting electrical energy, signals, or data in complex systems such as electrical equipment, automobiles, airplanes, and robots.

[0003] For example, CN218300821U discloses a household wire harness with a heat dissipation sleeve, including a base. Movable grooves are provided on both sides of the top of the base. A lead screw is disposed at the center of the base. Sliding grooves are provided on both sides of the bottom of the base. Threaded blocks are provided on both sides of the surface of the lead screw. A first arc-shaped plate and a second arc-shaped plate are respectively disposed on both sides of the top of the base. Heat dissipation fins are fixedly installed on the outer walls of both the first and second arc-shaped plates. An adjusting screw is threadedly connected to the center of the opposite side of the first and second arc-shaped plates.

[0004] In existing technologies, at the connection points of wire harnesses, localized heating is prone to occur due to current flow and contact resistance. If this area remains at high temperatures for an extended period, the insulation layer of the wire harness will age faster due to continuous thermal stress, gradually losing its elasticity and toughness, leading to a decline in insulation performance. When the insulation layer cracks or breaks due to high temperatures, the problem worsens. Damage to the insulation layer exposes the wires, increasing the risk of short circuits between the wires. Once a short circuit occurs between two wires, it can cause circuit overload, resulting in malfunction of electrical equipment or even burning out critical components. Utility Model Content

[0005] This utility model mainly provides a household wire harness with a heat dissipation sleeve that facilitates improved heat dissipation and prevents aging of the wire harness insulation layer.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a household wire harness with a heat dissipation sleeve, including a wire harness head, three connection ports are installed on one side of the wire harness head, a connection sleeve is fixedly connected to one side of the connection ports, and a heat dissipation mechanism is installed on one side of the connection sleeve.

[0007] The heat dissipation mechanism includes a heat dissipation sleeve body, a locking sleeve fixedly connected to one end of the heat dissipation sleeve body, a second threaded sleeve threadedly connected to the outer surface of the heat dissipation sleeve body, a plurality of elastic plates fixedly connected to one end of the heat dissipation sleeve body, a fixing frame fixedly connected to the outer surface of the elastic plates, a first threaded sleeve provided on one side of the elastic plates, the inner wall of the first threaded sleeve being threadedly connected to the connecting sleeve, a plurality of ropes fixedly connected to one side of the first threaded sleeve, a rope groove provided at the top of the fixing frame, and the ropes engaging with the rope groove.

[0008] Preferably, a cable is installed inside the connection port, and the heat dissipation sleeve body is fitted onto the outer surface of the cable. The heat-conducting block works in conjunction with the heat dissipation sleeve body to quickly dissipate the heat generated during cable operation, preventing excessive temperature from affecting cable performance.

[0009] Preferably, a notch is provided on one side of the locking sleeve, and a heat-conducting block is fixedly connected to the outer surface of the heat dissipation sleeve body. The notch design on the locking sleeve increases its flexibility, allowing for fine-tuning and thus achieving a more secure locking effect.

[0010] Preferably, a heat dissipation fin is fixedly connected to the outer surface of one end of the first threaded sleeve. The heat dissipation fin increases the heat dissipation area and effectively improves the heat dissipation efficiency.

[0011] Preferably, the inner diameter of the heat sink body is larger than the cable diameter, and the inner diameter of the first threaded sleeve is larger than the cable diameter. This facilitates quick and easy attachment to the outer surface of the cable.

[0012] Preferably, a limit ring is fixedly connected to the outer surface of one end of the locking sleeve. This prevents the second threaded sleeve from detaching from the heat sink body due to excessive rotation or external force, thereby ensuring the stability and reliability of the entire connection device.

[0013] Preferably, the outer diameter of the limiting ring is larger than the inner diameter of the second threaded sleeve. The limiting ring plays a crucial limiting role. As the second threaded sleeve gradually rotates and moves, when it contacts the limiting ring, the limiting ring can effectively prevent the second threaded sleeve from continuing to move, thus performing the function of position restriction.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, the position of the cable can be freely adjusted between the heat dissipation sleeve body and the first threaded sleeve for easy docking. Then, by tightening the second threaded sleeve, the locking sleeve clamps and fixes the cable surface, ensuring a stable connection. Next, the first threaded sleeve further pulls the sleeve rope and the fixing frame, pushing the elastic piece to tightly fit the cable. This not only enhances the stable connection between the cable and the heat dissipation sleeve body, but also improves the heat dissipation effect. The overall structure is compact, easy to install, and effectively avoids the risk of loosening or insufficient heat dissipation, ensuring the long-term stability and reliability of the system.

[0016] 2. In this utility model, one end of the locking sleeve adopts an open design, which facilitates quick installation. At the same time, the flexibility of the notch makes the locking effect more stable. With the use of the heat-conducting block and the heat dissipation sleeve body, the heat generated during operation can be efficiently dissipated, preventing the cable performance from being damaged by overheating. In addition, the first threaded sleeve ensures overall stability by being fixed with the connecting sleeve by threads. Its outer surface is provided with heat dissipation fins, which greatly improves heat dissipation efficiency. The overall heat dissipation design effectively reduces the temperature at the connection point of the cable and wire harness head, ensuring connection performance and safety, extending equipment life, and ensuring its long-term stability under high load operation.

Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Please see Figure 1 - Figure 4The present invention provides a technical solution: a household wire harness with a heat dissipation sleeve, including a wire harness head 1, three connection ports 11 installed on one side of the wire harness head 1, a connection sleeve 12 fixedly connected to one side of the connection ports 11, and a heat dissipation mechanism 3 installed on one side of the connection sleeve 12.

[0025] The heat dissipation mechanism 3 includes a heat dissipation sleeve body 35. A locking sleeve 37 is fixedly connected to one end of the heat dissipation sleeve body 35. A second threaded sleeve 38 is threadedly connected to the outer surface of the heat dissipation sleeve body 35. A plurality of elastic plates 36 are fixedly connected to one end of the heat dissipation sleeve body 35. A fixing frame 39 is fixedly connected to the outer surface of the elastic plates 36. A first threaded sleeve 31 is provided on one side of the elastic plates 36. The inner wall of the first threaded sleeve 31 is threadedly connected to the connecting sleeve 12. A plurality of ropes 32 are fixedly connected to one side of the first threaded sleeve 31. A rope groove 391 is provided at the top of the fixing frame 39. The ropes 32 are engaged with the rope groove 391.

[0026] During connection, the heat dissipation sleeve body 35 and the first threaded sleeve 31 are first sequentially fitted onto the outer surface of the cable 2. The inner diameter of both components is larger than the outer diameter of the cable 2, so they can move freely on the outer surface of the cable 2. This design facilitates adjustment of the connection end position of the cable 2, allowing it to be easily inserted into the connection port 11 and connected with the wire harness head 1.

[0027] After initial positioning, adjust the position of the heat sink body 35 according to actual needs to ensure it is in the ideal position. Next, begin tightening the second threaded sleeve 38. As it rotates, the second threaded sleeve 38 gradually moves, approaching the outer surface of the heat sink body 35 and near the limiting ring 372. During this process, the second threaded sleeve 38 gradually presses against the locking sleeve 37, causing the locking sleeve 37 to gradually approach and apply pressure to the surface of the cable 2, completing the clamping and locking of the cable 2.

[0028] After locking, the first threaded sleeve 31 is tightened to further strengthen the connection. As the first threaded sleeve 31 rotates, it moves the loops 32, thereby pulling multiple loops 32 located inside. During this pulling process, the multiple loops 32 work in conjunction with the fixing frame 39, causing the fixing frame 39 to gradually bring the elastic plate 36 closer to and press it firmly onto the cable 2. This process not only ensures the secure installation of the cable 2 but also increases the stability of the heat dissipation sleeve body 35. It can tightly fit the cable 2, effectively transfer heat, improve overall heat dissipation efficiency, and prevent loosening or instability, thus ensuring the long-term reliability and stability of the connection.

[0029] like Figure 2 As shown, a cable 2 is installed inside the connector 11, and a heat dissipation sleeve body 35 is fitted over the outer surface of the cable 2. The heat-conducting block 34 works in conjunction with the heat dissipation sleeve body 35 to quickly dissipate the heat generated during cable operation, preventing excessive temperature from affecting cable performance.

[0030] like Figure 4 As shown, a notch 371 is provided on one side of the locking sleeve 37, and a heat-conducting block 34 is fixedly connected to the outer surface of the heat dissipation sleeve body 35. The notch 371 on the locking sleeve 37 increases its flexibility, allowing for fine-tuning and thus achieving a more secure locking effect.

[0031] like Figure 3 As shown, a heat dissipation fin 33 is fixedly connected to the outer surface of one end of the first threaded sleeve 31. The heat dissipation fin 33 increases the heat dissipation area and effectively improves the heat dissipation efficiency.

[0032] like Figure 3 As shown, the inner diameter of the heat sink body 35 is larger than the diameter of the cable 2, and the inner diameter of the first threaded sleeve 31 is also larger than the diameter of the cable 2. This allows for convenient and quick fitting onto the outer surface of the cable 2.

[0033] like Figure 4 As shown, a limit ring 372 is fixedly connected to the outer surface of one end of the locking sleeve 37. This prevents the second threaded sleeve 38 from detaching from the heat sink body 35 due to excessive rotation or external force, thereby ensuring the stability and reliability of the entire connection device.

[0034] like Figure 4 As shown, the outer diameter of the limiting ring 372 is larger than the inner diameter of the second threaded sleeve 38. The limiting ring 372 plays a crucial limiting role. As the second threaded sleeve 38 gradually rotates and moves, when it contacts the limiting ring 372, the limiting ring 372 can effectively prevent the second threaded sleeve 38 from continuing to move, thus performing the function of position restriction.

[0035] The usage and working principle of this device are as follows: During connection, firstly, the heat sink body 35 and the first threaded sleeve 31 are fitted onto the outer surface of the cable 2. Since the inner diameter of both the heat sink body 35 and the first threaded sleeve 31 is larger than the diameter of the cable 2, they can be movably fitted onto the surface of the cable 2. This allows for easy control of the connection end of the cable 2, enabling it to be smoothly inserted into the connection port 11 and connected to the cable harness head 1. After determining the position of the heat sink body 35, first tighten the second threaded sleeve 38. The second threaded sleeve 38 will then move on the outer surface of the heat sink body 35, gradually approaching the limiting ring 372. During this process, the second threaded sleeve 38 will begin to compress the locking sleeve 37, causing the locking sleeve 37 to gradually approach the cable 2, thereby compressing it to complete the locking. Next, tighten the first threaded sleeve 31 to connect it to the connecting sleeve 12. During this process, the first threaded sleeve 31 will drive the sleeve rope 32 to move, thereby causing multiple sleeve ropes 32 to pull the fixing frame 39. During this process, the fixing frame 39 squeezes and drives the elastic plate 36 to gradually approach the cable 2, thereby completing the installation. This improves the stability of the installation during heat dissipation and prevents loosening.

[0036] Because the locking sleeve 37 has a notch at one end, it can be easily and quickly fitted onto the outer surface of the cable. The notch 371 also allows the locking sleeve 37 to move flexibly, thus locking the cable. The heat-conducting block 34, in conjunction with the heat-dissipating sleeve body 35, facilitates heat dissipation from the cable. During this process, the first threaded sleeve 31 is gradually installed on the outer surface of the connecting sleeve 12, and the heat dissipation fins 33 on the outer surface of one end of the first threaded sleeve 31 also improve the heat dissipation effect. During the use of the harness head 1, both the connecting sleeve 12 and the cable 2 can dissipate heat when they heat up, thus preventing the connection point between the cable 2 and the harness head 1 from becoming too hot.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
