Description

Technical Field

[0001] This application relates to the field of spring wire technology, and more specifically, to a shaped spring wire. Background Technology

[0002] Spring wire, also known as slingshot wire or spiral wire, is a highly practical type of equipment connection wire. Its main working principle is to fully utilize its stretchability to provide flexible power connections and signal transmission channels for movable equipment. Generally, spring wire is made of high-quality TPU cable, a material with excellent flexibility, abrasion resistance, and corrosion resistance, maintaining good performance in various complex working environments. In the automotive industry, spring wire is widely used for connecting components in automotive electronic devices and sensors. In machinery, spring wire is commonly used for connecting moving parts in automated production lines.

[0003] Existing spring wires lack overall rigidity, and their ability to resist deformation is limited when subjected to external tension or pressure, making them prone to excessive stretching and deformation. For example, in applications requiring the maintenance of specific lengths and shapes, such as connection lines in industrial equipment, existing spring wires may not meet the requirements, leading to circuit instability and affecting the reliability of connections between devices. Utility Model Content

[0004] To address the aforementioned problems, this application provides a shaped spring wire.

[0005] The technical solution for a shaped spring wire provided in this application is as follows:

[0006] A type of shaped spring wire includes an elastic wire body, with connecting blocks at both ends of the elastic wire body. The two ends of the elastic wire body extend through the connecting blocks and are connected to connectors.

[0007] The elastic wire body has a metal spring core inside, and a copper wire reinforcing layer is provided on the outside of the metal spring core. The copper wire reinforcing layer is used to enhance the overall rigidity of the elastic wire body, and an insulation layer is provided on the outside of the copper wire reinforcing layer.

[0008] One end of the connector is equipped with a sealing component.

[0009] Through the above technical solution, the presence of the copper wire reinforcement layer enhances the overall rigidity of the elastic wire body, making it less prone to excessive deformation under stress. Whether it is bending, stretching, or torsion in daily use, the elastic wire body can better maintain its shape.

[0010] Through the above technical solution, the sealing shell and plug can effectively prevent dust, moisture and other impurities from entering the plug. This can protect the conductive parts of the plug in various environments, avoid problems such as poor contact and short circuits caused by dust accumulation or moisture intrusion, extend the service life of the plug, and the sealing shell can provide a certain physical protection for the plug, preventing the plug from being damaged by accidental collisions, scratches and other damage when not in use.

[0011] Furthermore, the sealing assembly includes two sets, each set of sealing assemblies includes a telescopic rod, one end of which is rotatably connected to a connecting plate via a damping bearing, one end of which is connected to a sealing shell, and one end of which is connected to a first magnetic block. Each connector has two blocks at one end, and a rotating rod is provided on the inner side of each pair of blocks.

[0012] Furthermore, the outer wall of each rotating rod is fixedly connected to the telescopic rod, and a second magnetic block is provided at one end of each connector.

[0013] Furthermore, each pair of first magnetic blocks is magnetically connected to the corresponding second magnetic block, and each of the two connectors has a plug on the opposite side.

[0014] Furthermore, each of the two sealing shells is matched with a corresponding plug, and both sealing shells are made of transparent plastic.

[0015] Through the above technical solution, the transparent plastic sealing shell allows users to intuitively observe the status of the plug without opening the sealing shell, making it easy to determine whether the plug needs cleaning or repair.

[0016] Furthermore, both connecting blocks are made of plastic.

[0017] Through the above technical solution, the transparent plastic sealing shell allows users to intuitively observe the status of the plug without opening the sealing shell, making it easy to determine whether the plug needs cleaning or repair.

[0018] Furthermore, the cross-sections of both connecting blocks are annular.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] (1) Due to the presence of the copper wire reinforcing layer, the overall rigidity of the elastic wire body is enhanced, and it is not easy to deform excessively when subjected to force. Whether it is bending, stretching or twisting in daily use, the elastic wire body can better maintain its shape. This is very important for some application scenarios that require specific shape maintenance, such as inside electronic devices, which can avoid interference with other components due to the deformation of the elastic wire body and improve the overall reliability of the device.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figures 1-5 A type of shaped spring wire includes an elastic wire body 1, with connecting blocks 3 at both ends of the elastic wire body 1. Both ends of the elastic wire body 1 extend through the connecting blocks 3 (as shown in the figure, the connecting blocks 3 are enlarged schematic diagrams, and the actual diameter of the connecting blocks 3 is 0.2 mm larger than the diameter of the elastic wire body 1) and are then connected to a connector 4.

[0030] The elastic wire body 1 has a metal spring core 2 inside, and a copper wire reinforcing layer 14 is provided on the outside of the metal spring core 2. The copper wire reinforcing layer 14 is used to enhance the overall rigidity of the elastic wire body 1, and an insulating layer 13 is provided on the outside of the copper wire reinforcing layer 14.

[0031] One end of connector 4 is equipped with a sealing component.

[0032] The metal spring core 2 is the fundamental source of elasticity for the elastic wire body 1. When the elastic wire body 1 is stretched or compressed by an external force, the metal spring core 2 will undergo elastic deformation according to Hooke's Law. That is, under the action of external force, the spacing between the coils of the spring core will change. After the external force is removed, due to the elastic restoring force of the spring core material itself, it will be prompted to return to its original shape. For example, in daily use, if the elastic wire body 1 is stretched, the spring coils of the metal spring core 2 will be stretched apart, storing elastic potential energy; when the external force disappears, the metal spring core 2 will rely on its own elasticity to pull the elastic wire body 1 back to its original length.

[0033] The copper wire reinforcement layer 14 surrounds the outside of the metal spring core 2. When the elastic wire body 1 is subjected to external force, the copper wire reinforcement layer 14 enhances the overall rigidity. If the external force is axial tension or compression, the copper wire reinforcement layer 14 (especially the parallel copper wire structure) will provide additional support along the axial direction, limiting the excessive deformation of the metal spring core 2. For example, when the elastic wire body 1 is subjected to a large axial tension, the copper wire reinforcement layer 14 can prevent the metal spring core 2 from being excessively stretched, ensuring that the elastic wire body 1 maintains a relatively stable length within a certain range of external force. If the external force is lateral bending or torsional force, the copper wire reinforcement layer 14, which is woven into a mesh structure, can limit the deformation of the spring wire from multiple directions, so that the metal spring core 2 will not bend or twist excessively, thereby maintaining the shape stability of the elastic wire body 1.

[0034] Due to the presence of the copper wire reinforcement layer 14, the overall rigidity of the elastic wire body 1 is enhanced, and it is not easy to deform excessively when subjected to force. Whether it is bending, stretching or torsion in daily use, the elastic wire body 1 can better maintain its shape. This is very important for some application scenarios that require specific shape maintenance, such as inside electronic devices, which can prevent interference with other components due to the deformation of the elastic wire body 1 and improve the overall reliability of the device.

[0035] Reference Figures 2-3The sealing assembly includes two sets. Each set of sealing assemblies includes a telescopic rod 8. One end of the telescopic rod 8 is rotatably connected to a connecting plate 11 via a damping bearing. One end of the connecting plate 11 is connected to a sealing shell 5. One end of the sealing shell 5 is connected to a first magnetic block 6. Each connector 4 has two blocks 9 at one end. The inner side of each pair of blocks 9 is provided with a rotating rod 10. The outer wall of each rotating rod 10 is fixedly connected to the telescopic rod 8. Each connector 4 has a second magnetic block 12 at one end. Each pair of first magnetic blocks 6 is magnetically connected to the corresponding second magnetic block 12. Each pair of connectors 4 has a plug 7 on the opposite side.

[0036] The connectors 4 at both ends of the flexible cable body 1 are used to connect to external devices. When it is necessary to connect to an external device, the plug 7 on the opposite side of the connector 4 is prepared to be inserted into the interface of the external device.

[0037] Meanwhile, the sealing assembly on the connector 4 is in its initial state, the telescopic rod 8 is connected to the connecting plate 11 through the damping bearing, the connecting plate 11 is connected to the sealing shell 5, and the first magnetic block 6 at one end of the sealing shell 5 is in a magnetic attraction state with the second magnetic block 12 on the connector 4.

[0038] When both plugs 7 are in an idle state, pull the telescopic rod 8 to extend it, and then adjust the angle of the telescopic rod 8 by rotating the rotating rod 10. When it is rotated to a horizontal state, push the telescopic rod 8 inward so that the sealing shell 5 is aligned with the plug 7.

[0039] When plug 7 is in an idle state, the sealing shell 5, when in contact with plug 7, effectively prevents dust, moisture, and other impurities from entering the interior of plug 7. This protects the conductive parts of plug 7 in various environments, preventing problems such as poor contact and short circuits caused by dust accumulation or moisture intrusion, thus extending the service life of plug 7.

[0040] The sealing shell 5 provides a certain degree of physical protection for the plug 7, preventing it from being damaged by accidental impacts, scratches, or other injuries when not in use. For example, during storage or transportation, the sealing shell 5 can reduce the risk of damage to the plug 7.

[0041] After the sealing shell 5 has been left outside for a long time, it can be wiped with a paper towel to prevent dust from entering when the plug 7 is connected.

[0042] Reference Figures 1-4 The two sealing shells 5 are respectively matched with the corresponding plugs 7. Both sealing shells 5 are made of transparent plastic material. Both connecting blocks 3 are made of plastic material. The cross-section of both connecting blocks 3 is circular.

[0043] The two sealing shells 5 are respectively matched with the corresponding plugs 7, which means that the shape and size of the sealing shells 5 are designed according to the characteristics of the plugs 7. When the plugs 7 are not in use, the sealing shells 5 can fit tightly around the plugs 7 to form a closed space and prevent external impurities from entering the interior of the plugs 7.

[0044] The transparent plastic sealing shell 5 allows users to visually observe the status of the plug 7 without opening the sealing shell 5, making it easy to determine whether the plug 7 needs cleaning or maintenance.

[0045] The connecting block 3 is made of plastic and has a certain strength and toughness. The cross-section of the connecting block 3 is circular, which allows it to be tightly connected with the elastic wire body 1, thus fixing and protecting the elastic wire body 1.

[0046] Working principle: In actual use, when it is necessary to connect external equipment using this shaped spring wire, the connectors 4 at both ends of the elastic wire body 1 are brought close to the interface of the external equipment, so that the plugs 7 on the opposite side of the connectors 4 are ready to be inserted into the interface of the external equipment. At this time, the sealing assembly is in the initial state, that is, the telescopic rod 8 is connected to the connecting plate 11 through the damping bearing, the connecting plate 11 is connected to the sealing shell 5, and the first magnetic block 6 at one end of the sealing shell 5 is in a magnetic attraction state with the second magnetic block 12 on the connector 4. When the two plugs 7 are in an idle state, such as during storage or transportation, in order to protect the plugs 7, the telescopic rod 8 is first pulled to extend it, and then the angle of the telescopic rod 8 is adjusted by rotating the rotating rod 10. When rotated to the horizontal position, push the telescopic rod 8 inward to align the sealing shell 5 with the plug 7. Since the two sealing shells 5 are respectively matched to their corresponding plugs 7, and their shapes and sizes are designed according to the characteristics of the plugs 7, when the plug 7 is not in use, the sealing shell 5 can tightly fit around the plug 7, forming a sealed space. This effectively prevents external dust, moisture, and other impurities from entering the plug 7. This avoids problems such as poor contact or short circuits in the conductive parts of the plug 7 caused by dust accumulation or moisture intrusion, thus extending the service life of the plug 7. At the same time, the sealing shell 5 also provides a certain degree of physical protection for the plug 7, preventing damage from accidental collisions, scratches, etc., when it is not in use. For example, during transportation, the plug 7 may be subjected to bumps and vibrations; the sealing shell 5 can reduce the risk of damage to the plug 7.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
