Description

Technical Field

[0001] This utility model relates to the field of terminal wire technology, and in particular to a terminal wire with a waterproof sealing sleeve structure. Background Technology

[0002] Terminal wires are electronic wire harness assemblies composed of terminals and wires. Circuit connections are achieved by crimping or soldering terminals to both ends of the wires. They are widely used in electronic equipment, home appliances, automobiles and other fields to transmit current or signals.

[0003] Terminal wires with waterproof sealing sleeves are based on ordinary terminal wires, with an additional waterproof sealing sleeve at the connection between the terminal and the wire. The sleeve tightly wraps the connection part through elastic compression or heat shrinkage, preventing moisture, dust and other contaminants from entering, and ensuring stable transmission of current or signals in humid or harsh environments.

[0004] In existing technologies, the fixing effect of terminal wires plays a decisive role in the stability and safety of equipment operation, as terminal wires are key components for transmitting current and signals. Common terminal wire fixing methods mainly include cable tie binding and tape wrapping. Cable tie binding is difficult to adjust once it is tied, while tape wrapping is easily affected by environmental factors. In high temperature and humid environments, the adhesiveness of the tape will decrease rapidly, and repeated disassembly and assembly can easily lead to cable tie breakage, making it difficult to reuse. For wire harnesses of different specifications and quantities, it is often necessary to replace them with different models, and the wire harnesses may become loose or even fall off. Therefore, a terminal wire with a waterproof sealing sleeve structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a terminal wire with a waterproof sealing sleeve structure, which aims to improve the problem of cable tie breakage and difficulty in reuse in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A terminal wire with a waterproof sealing sleeve structure includes a connecting wire, a fixing block fixedly connected to the outside of the connecting wire, a connecting groove formed inside the fixing block, two springs I fixedly connected to the front inner wall of the connecting groove, an active block fixedly connected to the rear side of the two springs I, a lever fixedly connected to the front side of the active block, a connecting groove formed inside the fixing block, multiple springs II fixedly connected to the bottom inner wall of the connecting groove, a driven plate fixedly connected to the top of the multiple springs II, two driven posts fixedly connected to the top of the driven plate, a driven groove formed inside the fixing block, a wire harness rotatably connected to the left side of the fixing block, multiple limiting holes formed inside the wire harness, a connecting end fixedly connected to the front side of the connecting wire, and a reinforcing module sleeved on the outside of the connecting end;

[0008] As a further description of the above technical solution:

[0009] The reinforcing module includes a buffer layer, a sealing layer is provided on the outside of the buffer layer, and a hot melt adhesive layer is provided on the outside of the sealing layer;

[0010] As a further description of the above technical solution:

[0011] The external part of the active block is slidably connected to the inside of the connecting groove, and the external part of the driven plate is slidably connected to the inside of the connecting groove;

[0012] As a further description of the above technical solution:

[0013] The outer side of the driven column is in contact with the inner wall of the limiting hole, and the bottom of the driving block is in contact with the top of the driven plate;

[0014] As a further description of the above technical solution:

[0015] The outer side of the wire harness is slidably connected to the inside of the driven groove, and the inside of the buffer layer is honeycomb-shaped;

[0016] As a further description of the above technical solution:

[0017] The buffer layer is made of foamed silicone, and the sealing layer is made of silicone rubber;

[0021] The top of the connecting line has multiple connection points, and the buffer layer is sleeved over the outside of the connecting end.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by pressing the push block, the active block is driven to slide forward in the connecting groove, while the first spring is stretched. The wedge-shaped surface at the bottom of the active block presses against the wedge-shaped block on the front side of the driven plate, forcing the driven plate to slide downward against the elastic force of the second spring. This causes the driven post to disengage from the limiting hole of the wire harness. After the push block is released, the first spring returns to its original position and pushes the active block backward. The driven plate returns to its original position upward under the action of the second spring, and the driven post re-enters the limiting hole. This achieves the need to fix wire harnesses of different numbers and diameters, significantly improving wiring efficiency. The spring-driven mechanical linkage structure provides elastic buffering when fixing the wire harness, effectively absorbing vibration stress and reducing fatigue wear caused by rigid connection of the wire harness.

[0024] 2. In this utility model, the porous structure inside the honeycomb foamed silicone structure of the buffer layer disperses stress through the elastic deformation of the pore walls when subjected to vibration, bending or impact, protecting the connection point between the terminal and the wire. The middle silicone rubber sealing layer forms a continuous, non-porous elastic barrier, utilizing the material's own water resistance and low surface energy characteristics to prevent further penetration of moisture, oil and corrosive gases. The outer organic silicone hot melt adhesive layer penetrates into the micropores of the sealing layer after heating and melting, and forms a rigid adhesive layer after cooling and solidification. Thus, the complementary properties of the three layers of materials are achieved, which can not only adapt to the complex wire harness surface to achieve tight adhesion, but also improve the reliability of the terminal wire in complex environments such as humidity, vibration and high temperature through the synergistic effect of elastic deformation and rigid fixation.

[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] Reference Figures 1 to 3 This utility model provides an embodiment of a terminal wire with a waterproof sealing sleeve structure, including a connecting wire 1 for data transmission. A fixing block 2 is fixedly connected to the outside of the connecting wire 1, providing space for a connecting groove 3. The connecting groove 3 is formed inside the fixing block 2, providing fixation and support for springs 4. Two springs 4 are fixedly connected to the front inner wall of the connecting groove 3, providing elastic support for its driving block 5. The driving block 5 is fixedly connected to the rear side of the two springs 4. The driving block 5 is subjected to a force from a lever 6, which compresses the driven plate 9, causing it to slide down and thus disengage the driven column 10 from the interior of the limiting hole 13. A lever 6 is fixedly connected to the front side of the driving block 5. The operator presses the lever 6 to compress the wedge-shaped block on the front side of the driven plate 9, causing it to slide down.

[0033] The fixed block 2 has a connecting groove 7 inside, which provides fixation and support for the second spring 8. Multiple second springs 8 are fixedly connected to the bottom inner wall of the connecting groove 7. The second spring 8 has an elastic function and provides elastic support for its driven plate 9. The driven plate 9 is fixedly connected to the top of the multiple second springs 8. The driven plate 9 provides fixation and support for the driven post 10. At the same time, when it slides down, it can take the driven post 10 out of the interior of the limiting hole 13, thereby releasing the limiting fixation of the cable tie 12. Two driven posts 10 are fixedly connected to the top of the driven plate 9. The driven posts 10 are used to snap into the interior of the limiting hole 13, thereby completing the limiting fixation of the cable tie 12.

[0034] The fixed block 2 has a driven groove 11 inside, which is used for the passage of the cable tie 12. The cable tie 12 is rotatably connected to the left side of the fixed block 2. The cable tie 12 can fix other terminal wires when the terminal wire is used, and thus fix multiple lines for easy tidying. The cable tie 12 has multiple limiting holes 13 inside, which are used to cooperate with the driven post 10 to limit and fix the cable tie 12. The front side of the connecting wire 1 is fixedly connected to the connecting end 14, which is used to insert an external device for connection. The connecting end 14 is covered with a reinforcing module.

[0035] Reference Figure 1 and Figure 4 The reinforcement module includes a buffer layer 15. The buffer layer 15, through its porous structure and soft texture, effectively absorbs the mechanical stress generated by vibration, bending, or external pulling of the terminal wire during use, thereby protecting the connection point between the terminal and the wire. A sealing layer 16 is provided outside the buffer layer 15. The sealing layer 16 forms a continuous, non-porous elastic barrier outside the buffer layer 15, effectively preventing the intrusion of external substances such as moisture, dust, and oil, ensuring that the terminal wire maintains good electrical performance even in harsh environments such as humid and dusty conditions. A hot melt adhesive layer 17 is provided outside the sealing layer 16. During installation, the hot melt adhesive layer 17 is heated to melt, allowing it to fully penetrate the surface micropores of the sealing layer 16 and the gaps in the wire harness. After cooling and solidification, it forms a strong, rigid adhesive layer, which not only further enhances the sealing effect but also fixes the position of the terminal wire, preventing axial movement of the wire harness during use.

[0036] Reference Figures 2 to 4 The external of the active block 5 is slidably connected to the inside of the connecting groove 3. The connecting groove 3 provides a limiting and guiding function for the active block 5. The external of the driven plate 9 is slidably connected to the inside of the connecting groove 7. The connecting groove 7 provides a limiting and guiding function for the driven plate 9. The external of the driven post 10 is in contact with the inner wall of the limiting hole 13. The driven post 10 is used to be inserted into the inside of the limiting hole 13, thereby fixing the cable tie 12. The bottom of the active block 5 is in contact with the top of the driven plate 9. The active block 5 can squeeze the wedge block on the front side of the driven plate 9, thereby allowing the driven plate 9 to slide down. The external of the cable tie 12 is slidably connected to the inside of the driven groove 11. The driven groove 11 provides a limiting and guiding function for the cable tie 12.

[0037] The buffer layer 15 has a honeycomb structure inside. When the terminal wire is subjected to vibration, bending, or external impact, the honeycomb pores can evenly distribute stress in multiple directions, preventing excessive local stress. The buffer layer 15 is made of foamed silicone, which can tightly conform to the complex surface contours of the terminal and the wire, filling the irregular gaps between them. While providing buffer protection, it also assists the sealing layer 16 in initially blocking dust and moisture from entering, building the first line of defense for the stable operation of the terminal wire. The sealing layer 16 is made of silicone rubber, which can effectively prevent moisture, oil, corrosive gases, etc. from penetrating into the interior of the terminal wire, ensuring the reliability of the electrical connection.

[0038] The hot melt adhesive layer 17 is made of silicone hot melt adhesive. When heated to a certain temperature, it rapidly melts into a fluid colloid that can quickly penetrate the micropores on the surface of the sealing layer 16 and the tiny gaps in the wire harness. After cooling and curing, the silicone hot melt adhesive not only forms a hard protective shell on the outside of the terminal wire, firmly fixing the wire harness and preventing axial movement, but also provides multiple connection ports 18 inside the connecting wire 1 for data transmission with external device ports. Multiple connection points are provided on the top of the connecting wire 1 for power transmission. The buffer layer 15 is fitted over the outside of the connecting end 14, providing cushioning protection for the connecting end 14.

[0039] Working principle: When using terminal wires, if multiple external terminal wires need to be fixed, the operator presses the lever 6 to drive the active block 5 to slide forward in the connecting groove 3, while simultaneously stretching the spring 4. The wedge-shaped surface at the bottom of the active block 5 presses against the wedge-shaped block on the front side of the driven plate 9, forcing the driven plate 9 to slide downward against the elastic force of the second spring 8. This causes the driven post 10 to disengage from the limiting hole 13 of the cable tie 12. At this time, the cable tie 12 is unlocked and can slide freely in the driven groove 11. The user can wrap it around multiple terminal wires as needed. After releasing the lever 6, the spring 4 resets and pushes the active block 5 backward. The driven plate 9 resets upward under the action of the second spring 8, and the driven post 10 re-engages into the limiting hole 13, achieving rapid fastening of the cable tie. This structure, through spring-driven mechanical linkage, transforms manual operation into locking and unlocking of the cable tie 12, realizing stepless adjustment and elastic fixation of the cable tie, effectively buffering vibration stress, and avoiding fatigue breakage of the cable tie caused by rigid connection.

[0040] When the terminal wire is affected by the external environment, the porous structure inside the honeycomb foamed silicone structure of the buffer layer 15 disperses stress through the elastic deformation of the pore walls when subjected to vibration, bending or impact, protecting the connection point between the terminal and the wire. At the same time, the foamed silicone tightly adheres to the irregular surface of the connection end 14, initially blocking the intrusion of dust and moisture. The middle silicone rubber sealing layer 16 forms a continuous, non-porous elastic barrier, utilizing the material's own water resistance and low surface energy characteristics to prevent further penetration of moisture, oil, and corrosive gases. The outer organic silicone hot melt adhesive layer 17 penetrates into the micropores of the sealing layer 16 after heating and melting, and forms a rigid adhesive layer after cooling and solidification. This not only enhances the sealing effect but also firmly fixes the wire harness in the equipment, preventing sealing failure caused by axial movement. The three-layer structure, through the complementary material properties, provides a triple protection mechanism that significantly improves the reliability of the terminal wire in complex environments such as humidity, vibration, and high temperature.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
