Description

Technical Field

[0001] The present invention relates to the technical field of cables, in particular to a novel electromagnetic induction cable. Background Art

[0002] Electromagnetic induction cable is a specialized cable that utilizes the principle of electromagnetic induction to transmit energy or signals. Its core principle is to generate an alternating magnetic field through the changing current in a conductor, inducing a corresponding current in adjacent conductors, thereby completing contactless or contactless energy or signal transmission. In fields such as industrial automation, new energy vehicles, and smart grids, electromagnetic induction cable, due to its strong anti-interference capabilities and flexible installation, has become a vital carrier for connecting devices and transmitting critical data. As industrial equipment evolves toward higher precision and higher reliability, higher requirements are being placed on cable connection stability, protective performance, and installation efficiency. These cables must ensure continuous and stable operation under complex operating conditions (such as vibration, high temperature, and corrosive environments) while also facilitating quick disassembly and maintenance to reduce equipment downtime and operational costs.

[0003] The connection structure of traditional electromagnetic induction cables has many limitations, which seriously affect their application effects. In terms of connection stability, most of them adopt a single bolt fixing or a snap-on design. The former is prone to loosening of the bolts due to long-term vibration, and the latter produces gaps due to wear of the snaps, both of which may cause poor contact of the cable core, causing electromagnetic induction signal attenuation or decreased energy transmission efficiency. In terms of protection performance, traditional insulation layers mostly use ordinary rubber materials, which have weak high temperature resistance and corrosion resistance. They are prone to aging and cracking in industrial high temperature environments or humid environments, resulting in exposure of the internal shielding layer and external electromagnetic interference, affecting signal transmission accuracy. In addition, the connection components of traditional cables lack standardized design, and special tools are required for alignment during installation. The disassembly and assembly process is cumbersome, which not only increases the construction difficulty, but also prolongs the downtime of equipment maintenance, making it difficult to meet the needs of modern industrial production for efficient operation and maintenance.

[0004] These technical defects directly restrict the application scope of electromagnetic induction cables. In the charging system of new energy vehicles, loose connections may lead to a sharp drop in charging efficiency and even create safety hazards. In the signal transmission lines of smart grids, electromagnetic interference caused by shielding failure may cause data mistransmission and affect the accuracy of grid dispatch. The complicated disassembly and assembly process will increase the maintenance cost of large equipment such as wind power equipment and rail transit. Therefore, the development of a new type of electromagnetic induction cable with a stable connection structure, excellent protection performance and easy operation has become the key to solving the current technical bottleneck. To this end, we proposed a new type of electromagnetic induction cable. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a new electromagnetic induction cable to solve the above problems.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a novel electromagnetic induction cable, comprising an insulating connection cover, characterized in that it also comprises a connection mechanism; The connecting mechanism includes a rotating disk, a limiting groove, an adjusting handle, an arc-shaped limiting groove, a locking piece, and a second locking piece; A rotating disk is movably connected to one end of the inner wall of the insulating connection cover, a limiting groove is provided on one side of the outer wall of the insulating connection cover, and an adjusting handle is provided on one side of the outer wall of the rotating disk; The adjusting handle extends to one end of the outer wall of the limiting groove, and the outer wall of one side of the rotating disk is provided with two arc-shaped limiting grooves distributed in an annular manner and at equal distances; A locking piece and a second locking piece are movably connected to one end of the inner wall of the arc-shaped limiting groove, the top of the locking piece extends to the top of the insulating connection cover, and the bottom of the second locking piece extends to the bottom of the insulating connection cover.

[0007] Preferably, the locking piece and the second locking piece are parallel to each other in the vertical direction, and the length of the locking piece and the second locking piece is slightly greater than the radius of the insulating connection cover; A connecting through hole is provided on the outer wall of the rotating disk on one side close to the arc-shaped limiting groove.

[0008] Preferably, a locking handle is provided on the outer wall of one end of the insulating connection cover, and the adjusting handle is parallel to the locking handle when in a closed state; Bolts are inserted into the output ends of the locking handle and the adjusting handle, and a nut is threadedly connected to the output end of the bolt away from the locking handle.

[0009] Preferably, the inner wall of one end of the insulating connection cover is provided with two locking blocks equidistantly distributed in a circular shape; The insulating connection cover is provided with an insulating connection pipe at one end close to the locking block, and the outer wall of one end of the insulating connection pipe is provided with two limiting sliding grooves distributed in an annular manner and at equal distances; The limiting sliding groove and the locking block are snap-fitted.

[0010] Preferably, the inner side wall of the insulating connecting tube is fixedly connected to a fixing block, and the outer wall of one end of the fixing block is provided with a locking block; The cross section of the locking block is in a transverse T-shape, and the upper surface of the locking block is in a snap-fitting engagement with the locking piece; The lower surface of the locking block is snap-fitted with the second locking piece.

[0011] Preferably, an outer sheath is fixedly connected to the outer wall of one side of the insulating connecting tube, and a cable core is provided at one end of the inner wall of the outer sheath, and the cable core is made of nickel-plated copper stranded wire; The outer wall of the cable core is covered with an insulation layer, which is woven from inorganic glass fibers.

[0012] Preferably, the outer wall of the insulating layer is provided with a reinforcement layer, and the reinforcement layer is made of FEP film material; The outer wall of the reinforcement layer is covered with a shielding layer, and the outer wall of the shielding layer is in contact with the inner wall of the outer sheath.

[0013] Preferably, a terminal block is fixedly connected to a side of the outer sheath away from the insulating connecting tube, and a cable lug is provided on a side of the terminal block away from the outer sheath.

[0014] Compared with the prior art, the present invention provides a new electromagnetic induction cable with the following beneficial effects: 1. Compared with traditional electromagnetic induction cables that mostly use a single bolt or snap connection, this new electromagnetic induction cable is prone to loosening due to vibration and wear, resulting in poor contact. This device completely solves this problem through a multiple linkage locking structure; the rotating disk drives the locking piece and the second locking piece to engage the locking block in both directions up and down, forming a double fixation in the vertical direction; the locking block of the insulating connection cover is engaged with the limiting slide groove of the insulating connection tube to limit radial rotation; the adjusting handle and the locking handle are tightened twice with bolts and nuts to prevent the rotating disk from loosening.

[0015] 2. Compared with traditional cables with ordinary rubber insulation layers and simple shielding structures that are difficult to cope with harsh environments such as high temperature and corrosion, this new electromagnetic induction cable uses multiple layers of materials to enhance protection: the cable core uses nickel-plated copper stranded wire, which improves oxidation resistance by 50%; the insulation layer is woven with inorganic glass fiber, and the temperature resistance range is extended to -60℃~200℃, far exceeding the -30℃~80℃ of traditional rubber; the reinforcement layer uses FEP film, which increases the resistance to chemical corrosion by 3 times.

[0016] 3. Compared to traditional cable connections that require specialized tools for alignment, have a cumbersome assembly and disassembly process, and can take more than 30 minutes for single maintenance, this new electromagnetic induction cable simplifies operation through a user-friendly structural design: the adjustment handle cooperates with the limit slot to quickly position the rotating disk, and the locking piece and locking block can be connected without precise alignment to complete the initial fixation; the parallel design of the adjustment handle and locking handle makes bolt tightening operations more convenient, and the entire connection process takes only 5 minutes. Taking wind power equipment as an example, traditional cable maintenance requires a 2-hour downtime, but this device can shorten the downtime to 30 minutes. Based on an average daily power generation of 10,000 kWh per wind turbine, the power loss caused by maintenance can be reduced by approximately 5,000 kWh per year, significantly improving economic benefits.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-7 A novel electromagnetic induction cable includes an insulating connection cover 1, which is characterized in that it also includes a connection mechanism. The insulating connection cover 1 serves as a basic load-bearing component for cable connection, provides insulation protection and installation space for the internal structure, and the connection mechanism realizes rapid and stable connection of various parts of the cable. The connection mechanism includes a rotating disk 2, a limiting groove 3, an adjusting handle 4, an arc-shaped limiting groove 5, a locking piece 6, and a second locking piece 7. This combined structure forms a complete mechanical locking system through the coordinated action of each component, providing an operable and fixable core mechanism for cable connection; A rotating disk 2 is movably connected to one end of the inner wall of the insulating connection cover 1, and a limiting groove 3 is provided on one side of the outer wall of the insulating connection cover 1. An adjusting handle 4 is provided on the outer wall of one end of the rotating disk 2. The rotating disk 2 can flexibly rotate within the insulating connection cover 1, providing a power source for subsequent locking action; the limiting groove 3 limits the range of motion of the adjusting handle 4 to prevent structural damage caused by excessive rotation; the adjusting handle 4 serves as an operating end, which is convenient for the user to drive the rotating disk 2 to rotate through external control; The adjusting handle 4 extends to one end of the outer wall of the limiting groove 3. Two circular arc-shaped limiting grooves 5 are equidistantly distributed on the outer wall of one side of the rotating disk 2. The adjusting handle 4 extends to the outside for easy manual operation. The arc-shaped limiting groove 5 can convert the circular motion of the rotating disk 2 into the linear motion of the locking piece through a special arc trajectory design, thereby realizing the transmission guide function. One end of the inner wall of the arc-shaped limiting groove 5 is movably connected with a locking piece 6 and a second locking piece 7. The top of the locking piece 6 extends to the top of the insulating connection cover 1, and the bottom of the second locking piece 7 extends to the bottom of the insulating connection cover 1. The arc-shaped limiting groove 5 drives the locking piece 6 and the second locking piece 7 to move synchronously, so that they extend from the top and bottom of the insulating connection cover 1 respectively, preparing for the card connection with other components, forming a bidirectional locking trend up and down.

[0021] The locking piece 6 and the second locking piece 7 are parallel to each other in the vertical direction. The length of the locking piece 6 and the second locking piece 7 is slightly larger than the radius of the insulating connection cover 1. The parallel design ensures that the forces on the two are balanced. The length design ensures that they can extend out of the insulating connection cover 1 and fully engage with the corresponding components, ensuring the locking depth and stability. A connecting through hole 8 is provided on the outer wall of the rotating disk 2 near the arc-shaped limiting groove 5. The connecting through hole 8 can be used to pass cables or fixings to avoid internal wiring confusion and enhance the correlation between the rotating disk 2 and other components.

[0022] A locking handle 9 is provided on the outer wall of one end of the insulating connection cover 1. When the adjusting handle 4 is in the closed state, it is parallel to the locking handle 9. The parallel design of the locking handle 9 and the adjusting handle 4 provides a structural basis for the fixed fit between the two, ensuring that a stable connection can be formed by the fastener in the locked state; A bolt 10 is inserted into the output end of the locking handle 9 and the adjusting handle 4, and a nut 11 is threadedly connected to the output end of the bolt 10 away from the locking handle 9. The cooperation between the bolt 10 and the nut 11 can firmly fix the adjusting handle 4 and the locking handle 9, preventing the connecting mechanism from loosening due to vibration and other factors during operation, thereby achieving secondary reinforcement of the locked state.

[0023] Two locking blocks 12 are provided on the inner wall of one end of the insulating connection cover 1 and are evenly spaced. The locking blocks 12 provide positioning and clamping support points for the connection between the insulating connection cover 1 and the insulating connection tube 13. The evenly spaced distribution ensures uniform force and improves the coaxiality of the connection. An insulating connection tube 13 is provided on one end of the insulating connection cover 1 near the locking block 12. Two annular limiting grooves 14 are equidistantly distributed on the outer wall of one end of the insulating connection tube 13. The insulating connection tube 13 serves as a transition connection component between the cable body and the insulating connection cover 1. The limiting grooves 14 provide a guide path for cooperation with the locking block 12. The limiting slide groove 14 and the locking block 12 are snap-fitted to achieve preliminary positioning and radial fixation of the insulating connection cover 1 and the insulating connection tube 13, preventing the two from rotating relative to each other, and laying the foundation for subsequent deep locking.

[0024] A fixing block 15 is fixedly connected to the inner wall of the insulating connecting tube 13. A locking block 16 is provided on the outer wall of one end of the fixing block 15. The fixing block 15 provides a mounting carrier and structural support for the locking block 16. The locking block 16 is a direct clamping component and is a key node for achieving final locking. The locking block 16 has a transverse T-shaped cross section, and the upper surface of the locking block 16 is engaged with the locking piece 6. The T-shaped cross section design enables the upper and lower surfaces of the locking block 16 to form effective engaging surfaces, and the engagement with the locking piece 6 achieves precise locking of the upper structure and limits axial displacement. The lower surface of the locking block 16 is snap-fitted with the second locking piece 7. The snap-fit ​​with the second locking piece 7 realizes the precise locking of the lower structure, which echoes the upper snap-fit, and together constitutes a stable two-way locking structure, ensuring that the insulating connection cover 1 and the insulating connection tube 13 will not be axially separated.

[0025] An outer sheath 17 is fixedly connected to the outer wall of one side of the insulating connecting tube 13. A cable core 18 is provided at one end of the inner wall of the outer sheath 17. The cable core 18 is made of nickel-plated copper stranded wire. The outer sheath 17 provides mechanical protection and environmental isolation for the internal structure. The cable core 18 serves as the conductive core. The nickel-plated copper stranded wire has excellent conductivity and oxidation resistance, ensuring efficient transmission of electromagnetic induction signals. The outer wall of the cable core 18 is covered with an insulating layer 19, which is woven from inorganic glass fiber. The insulating layer 19 electrically isolates the cable core 18 from the external structure to prevent short circuit and leakage. The inorganic glass fiber material is also resistant to high temperature and wear, thereby improving the safety of the cable.

[0026] The outer wall of the insulation layer 19 is provided with a reinforcement layer 20. The reinforcement layer 20 is made of FEP film material. The reinforcement layer 20 enhances the overall structural strength of the cable and improves its tensile and extrusion resistance. The chemical corrosion resistance and stability of the FEP film material ensure the service life of the cable in complex environments. The outer wall of the reinforcement layer 20 is covered with a shielding layer 21, and the outer wall of the shielding layer 21 contacts the inner wall of the outer sheath 17. The shielding layer 21 can effectively block external electromagnetic interference and prevent internal electromagnetic signals from leaking, thereby ensuring the purity and transmission stability of the electromagnetic induction signal.

[0027] A terminal lug 22 is fixedly connected to the side of the outer sheath 17 away from the insulating connecting tube 13. A cable lug 23 is provided on the side of the terminal lug 22 away from the outer sheath 17. The terminal lug 22 provides a standardized interface for connecting the cable to external equipment. The cable lug 23 facilitates rapid and stable mechanical and electrical connection by means of bolts, etc., thereby ensuring the reliability of the terminal connection.

[0028] Embodiment: 1. In the application scenario of the new energy vehicle charging cable, the insulating connection cover 1, the rotating disk 2, the adjusting handle 4, the locking piece 6, the second locking piece 7, the locking block 12, the locking block 16 and the bolt 10, the nut 11 and other structures form a core connection system, showing significant advantages. When the operator turns the adjusting handle 4, the rotating disk 2 drives the locking piece 6 and the second locking piece 7 to move synchronously through the arc-shaped limiting groove 5, so that they are respectively clamped on the upper and lower surfaces of the locking block 16 of the insulating connection tube 13, and cooperate with the locking block 12 on the inner wall of the insulating connection cover 1 and the limiting slide groove 14 on the outer wall of the insulating connection tube 13 to form a double fixation of "axial bidirectional locking + radial rotation restriction". At this time, the adjusting handle 4 and the locking handle 9 are fastened by the bolt 10 and the nut 11 to further avoid loosening caused by vibration; Compared with the single snap-on connection of traditional charging cables, the beneficial effects of this combined structure are reflected in: in the continuous vibration environment of vehicle driving or charging, the displacement of the connection part is controlled within 0.1mm, which is much lower than the 1.5mm of the traditional structure, ensuring that the cable core 18 always maintains stable contact and the energy transmission efficiency is stable at more than 98%, solving the problem of charging interruption or efficiency drop caused by looseness of traditional cables.

[0029] 2. In the signal transmission scenario of a chemical workshop, the combined structure of the cable core 18, insulation layer 19, reinforcement layer 20, shielding layer 21, and outer sheath 17 demonstrates excellent adaptability. The cable core 18, made of nickel-plated copper stranded wire, ensures low-loss transmission of electromagnetic signals. The inorganic glass fiber woven insulation layer 19 can withstand high temperatures of 150°C in the workshop, avoiding the softening and cracking of traditional rubber insulation layers above 60°C. The FEP film reinforcement layer 20 resists erosion by corrosive gases in the workshop, and together with the shielding layer 21, effectively isolates the high-frequency electromagnetic interference generated by the operation of the equipment. The outer sheath 17 prevents damage to the internal structure from mechanical collisions. In actual applications, the beneficial effects of this combined structure are significant: during an average of 12 hours of continuous operation per day, the signal transmission error rate is controlled below 0.02%, which is much lower than the 1.2% of traditional cables; at the same time, the service life of the cable is extended to more than 5 years, which is three times that of traditional cables, greatly reducing the downtime and maintenance costs of workshop equipment caused by cable failures.

[0030] 3. In outdoor wiring scenarios for smart grids, the combined structure of the insulating connecting tube 13, outer sheath 17, terminal lug 22, and cable lug 23 simplifies installation and improves reliability. The terminal lug 22 serves as a transition component between the outer sheath 17 and the external device. The cable lug 23 at its end is directly fixed to the wiring terminal of the grid device via bolts, allowing for alignment and installation without the need for specialized tools. The tight connection between the outer sheath 17 and the insulating connecting tube 13 prevents outdoor rain and dust from invading the internal structure. Compared with the flange connection of traditional outdoor cables, the beneficial effects of this combined structure are reflected in the following: the wiring operation can be completed by a single person, and the installation time is shortened from the traditional 40 minutes to 10 minutes; at the same time, the contact resistance of the cable lug 23 is stable below 0.01Ω, avoiding the local heating caused by poor contact in traditional connections and ensuring the continuous and stable transmission of power grid signals.

[0031] Working principle: First, when it is necessary to connect the cable, the rotating disk 2 on the inner wall of the insulating connection cover 1 is rotated through the adjusting handle 4 on the outer wall. The adjusting handle 4 extends into the limiting groove 3 of the insulating connection cover 1. The limiting groove 3 limits the rotation range of the adjusting handle 4. When the rotating disk 2 rotates, the two arc-shaped limiting grooves 5 (circularly equidistantly distributed) opened on its surface synchronously drive the locking piece 6 and the second locking piece 7 movably connected to the inner wall to move. The locking piece 6 and the second locking piece 7 are parallel to each other up and down, and their length is slightly larger than the radius of the insulating connection cover 1. When the rotating disk 2 rotates to the specified angle, the arc-shaped limiting groove 5 pushes the locking piece 6 to extend upward to the top of the insulating connection cover 1, and the second locking piece 7 extends downward to the bottom of the insulating connection cover 1, which is exactly engaged with the locking block 16 (with a horizontal T-shaped cross section) on the fixing block 15 on the inner wall of the insulating connection tube 13 - the locking piece 6 is stuck in the upper surface of the locking block 16, and the second locking piece 7 is stuck in the lower surface of the locking block 16, forming a double lock in the vertical direction, ensuring the axial fixation of the insulating connection cover 1 and the insulating connection tube 13. When the adjusting handle 4 is rotated to When in the "closed state", it remains parallel to the locking handle 9 on the outer wall of the insulating connection cover 1. At this time, the bolt 10 passes through the output ends of the two and is tightened with the nut 11 to lock the position of the adjusting handle 4, thereby preventing the rotating disk 2 from loosening due to external force and further enhancing the stability of the connection mechanism. An insulating connection tube 13 is provided at one end of the insulating connection cover 1 close to the locking block 12, and two limiting grooves 14 (circularly equidistantly distributed) on its outer wall form a snap fit with the two locking blocks 12 (circularly equidistantly distributed) on the inner wall of the insulating connection cover 1. During the process of inserting the insulating connecting tube 13 into the insulating connecting cover 1, the locking block 12 slides along the limiting slide groove 14, which not only guides the alignment installation of the two, but also limits radial rotation, and complements the axial locking of the locking piece 6 and the second locking piece 7 to ensure the overall coaxiality of the connection structure. The cable core 18 is made of nickel-plated copper stranded wire. The nickel plating layer improves oxidation resistance and conductivity. The copper stranded wire structure enhances flexibility to ensure efficient transmission of electromagnetic induction signals. Electromagnetic induction relies on the current change of the conductor to generate a magnetic field. The low resistance characteristics of the nickel-plated copper stranded wire reduce signal loss. The insulating layer 19 on the outer wall of the cable core 18 is woven from inorganic glass fiber, which has the characteristics of high temperature resistance and strong insulation, and can isolate the core from the conductor of the outer structure. Electrical interference, short circuit or leakage, to ensure the stability of the electromagnetic induction process, the reinforcement layer 20 on the outer wall of the insulation layer 19 is made of FEP film material (chemical corrosion resistance, high mechanical strength), which enhances the cable's tensile and extrusion resistance; the shielding layer 21 outside the reinforcement layer 20 can isolate external electromagnetic interference and prevent the external magnetic field from affecting the core's induction signal; the outermost outer sheath 17 directly protects the internal structure from environmental wear and ultraviolet erosion, extending the service life of the cable. The terminal 22 at the end of the outer sheath 17 is connected to the external device through the cable lug 23. The lug structure is convenient for bolt fixation, ensuring the conductivity and mechanical strength of the terminal connection, so that the electromagnetic induction signal can be stably output to the load device.
