Description

Technical Field

[0001] The present invention relates to the technical field related to high voltage wires, and in particular to a high voltage connecting wire with a fixed shape and a shielding function. Background Art

[0002] High-voltage conductors are components that play a vital role in power transmission and distribution systems. High-voltage connecting conductors are mainly used to transmit high-voltage and high-current electrical energy. During the power transmission process, according to Ohm's law, when current passes through the conductor, energy loss will be generated on the conductor resistance, and the lost energy will be dissipated in the form of heat. In order to reduce this loss, when transmitting a certain power of electrical energy, it is necessary to increase the voltage and reduce the current. Therefore, in the power plant, the voltage output by the generator will be increased through a transformer, and then transmitted over long distances through high-voltage connecting conductors. When the electrical energy is transmitted to the power consumption area, the voltage is reduced through a step-down transformer. To a voltage level suitable for users, in order to facilitate inspection and maintenance, and to avoid damage to the wires by natural factors such as underground moisture and crustal movement, high-voltage connecting wires are usually suspended. This can ensure the stability and reliability of power transmission, and can be more easily checked and repaired when a fault occurs. Due to the increasingly fierce competition in new energy vehicles in recent years, various OEMs have vigorously promoted cost reduction and efficiency improvement. The complexity of the vehicle wires and the soft characteristics of the wires themselves make it the most difficult part of realizing the automated installation of the vehicle. Therefore, a high-voltage connecting wire with a fixed shape and shielding function is particularly needed.

[0003] However, the existing high-voltage connecting wires used in traditional fuel vehicles are composed of multiple metal wires, which are soft and have unstable shapes. Soft conductors are usually more susceptible to deformation due to external forces. During installation, use or transportation, their shapes may change due to squeezing, bending or stretching, which may affect the electrical performance of the wires and the reliability of the connection. Summary of the invention

[0004] The purpose of the present invention is to provide a high-voltage connecting wire with a fixed shape and a shielding function, so as to solve the problem of an existing high-voltage connecting wire with a fixed shape and a shielding function proposed in the above background technology. However, the existing high-voltage connecting wire, the wire conductor used in traditional fuel vehicles is a plurality of metal wires, which are soft and have no fixed shape. The soft conductor is usually more susceptible to deformation by external force. During installation, use or transportation, the shape may change due to squeezing, bending or stretching, which may affect the electrical performance of the wire and the reliability of the connection.

[0006] The supporting mechanism comprises a first supporting block, a slot, a second supporting block, a blocking block, a telescopic hole, a telescopic spring, a limiting plate, a fixed block and a fixed hole; the outer surface of the sleeve is movably connected with the first supporting block, the inner surface of the first supporting block is provided with a slot, the outer surface of the sleeve is movably connected with the second supporting block, one end surface of the second supporting block is fixedly connected with the blocking block, the inner surface of the blocking block is provided with a telescopic hole, one end surface of the inner wall of the telescopic hole is fixedly connected with the telescopic spring, the outer end surface of the telescopic spring is fixedly connected with the limiting plate, the outer end surface of the limiting plate is fixedly connected with the fixed block, and the inner surface of the blocking slot is provided with a fixing hole.

[0007] Preferably, the metal conductor is made of copper material, and its conductivity is not less than %IACS.

[0008] Preferably, the materials of the first insulating layer and the second insulating layer are mainly silicone, and the material of the shielding layer is composed of aluminum foil.

[0009] Preferably, the steel wires and support pads are arranged in multiple groups inside the metal conductor, and the steel wires and support pads in each group are distributed at equal intervals.

[0010] Preferably, the support pad is made of rubber, which has good elasticity and wear resistance.

[0011] Preferably, the material of the anti-corrosion layer is epoxy resin coating with a thickness of 0.2mm-0.5mm, the material of the high temperature resistant layer is ceramic fiber material which can withstand a temperature range of 800℃-1200℃, and the material of the wear resistant layer is polytetrafluoroethylene with a thickness of 0.1mm-0.3mm.

[0012] Preferably, the sizes of the first support block and the second support block match each other, and the first support block and the second support block cooperate with each other to support the sheath.

[0013] Preferably, the position of the card block corresponds to the position of the card slot, and the outer wall size of the card block matches the inner wall size of the card slot.

[0014] Preferably, the limit plate cooperates with the fixed block through a telescopic spring to form a telescopic structure, and the limit plate slides inside the telescopic hole.

[0015] Preferably, the position of the fixing block corresponds to the position of the fixing hole, and the outer wall size of the fixing block matches the inner wall size of the fixing hole.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the shape-fixed high-voltage connecting wire with shielding function is provided with steel wire, support pad and support mechanism. When the high-voltage connecting wire needs to be supported and fixed, the first support block and the second support block are firstly approached from both sides of the sheath respectively. As the second support block approaches, the clamping block slowly pushes into the clamping groove on the inner surface of the first support block. In this process, the fixed block begins to be squeezed by the inner wall of the clamping groove. Due to the force of the inner wall of the clamping groove, the fixed block gradually moves into the telescopic hole. This movement process is very delicate. It pushes the limit plate, and the limit plate also slides smoothly in the telescopic hole, thereby compressing the telescopic spring. The telescopic spring is gradually compressed in this process, storing elastic potential energy. When the card block completely enters the card slot, the fixed block pops out accurately under the elastic restoring force of the telescopic spring. This pop-up action is quick and accurate, so that the fixed block is aligned with the fixing hole on the inner surface of the card slot and inserted into it. The completion of this series of actions realizes the fixed connection between the first support block and the second support block. At this time, the first support block and the second support block are jointly surrounded by the outer surface of the sheath, providing stable support for the high-voltage connecting wire. When subjected to external pressure or vibration, the support mechanism can give full play to its structural strength and elastic buffering effect. When external force acts on the wire, the support mechanism first bears most of the pressure and disperses the pressure to various parts through its rigid structure. At the same time, the elastic buffering effect of the telescopic spring also begins. It is shown that when subjected to vibration, the telescopic spring can absorb and alleviate the vibration energy and prevent the vibration from being transmitted to the inside of the wire, thereby protecting the internal wire structure and preventing the wire from being deformed or damaged by external force. This movably connected support mechanism is extremely convenient. It is easy to install and disassemble, and can be adjusted and replaced according to actual needs. During the installation process, the operator can easily assemble the first support block and the second support block without complicated tools and cumbersome steps. When adjustment or replacement is required, it can be completed quickly by simply following the reverse steps. This feature greatly improves the flexibility and adaptability of the high-voltage connecting wire, allowing the wire to be adjusted and optimized under different environments and needs. The first support block and the second support block fit closely together and surround the outside of the sheath to provide rigid support for the entire high-voltage connecting wire. This rigid support allows the wire to maintain a fixed shape in various environments. Compared with the soft and easily deformed wires of traditional fuel vehicles, it has obvious advantages. The wires of traditional fuel vehicles are easily deformed by external forces, which may cause unstable electrical performance and loose connections. The shape-fixed characteristics of the high-voltage connecting wire greatly improve the reliability of the wire during installation and use. During the installation process, the wire with a fixed shape is easier to position and connect, reducing the possibility of installation errors. During use, even if it is affected by external forces, the wire can maintain a stable shape to ensure the stability of electrical performance.It avoids loose connection and failure caused by shape change. In addition, the support mechanism provides rigid support from the outside of the conductor, while the steel wire and support pad play a supporting role inside the metal conductor. From the internal structure point of view, the layout of the steel wire and support pad is reasonable, and the support pads distributed at equal intervals make the support effect of the steel wire more uniform. When the conductor is subjected to external force, the steel wire enhances the overall strength of the metal conductor with its high strength to prevent it from deformation or breakage. The support pad plays a buffering role between the steel wire and the metal conductor, reducing the direct impact of external force on the metal conductor. The combination of inside and outside jointly builds a stable structural system for the high-voltage connection conductor. Whether in static installation or in dynamic use, this structural system can effectively resist various external force interference. During static installation, the support mechanism, steel wire and support pad work together to ensure that the shape of the conductor is stable and does not deform or twist.

Compared with the soft and deformable wires of traditional fuel vehicles, this fixed shape feature greatly improves the reliability of the wire during installation and use, and avoids the problems of unstable electrical performance and loose connection due to shape changes.

[0028] Furthermore, the metal conductor 1 is made of copper material, and its conductivity is not less than 95% IACS. The provision of the metal conductor 1 ensures efficient transmission of electric energy in the high-voltage connecting wire, reduces power loss due to high resistance, and improves the efficiency of power transmission.

[0029] Furthermore, the materials of the first insulating layer 2 and the second insulating layer 4 are mainly silicone, and the material of the shielding layer 3 is composed of aluminum foil. Through the arrangement of the first insulating layer 2, the shielding layer 3 and the second insulating layer 4, the first insulating layer 2 and the second insulating layer 4 are made of silicone material, which has good insulation performance, provides double protection for the wires, effectively prevents leakage and electric shock accidents, and improves safety of use. The aluminum foil material of the shielding layer 3 can effectively shield external electromagnetic interference, reduce the impact of electromagnetic radiation on the surrounding environment and equipment, and also reduce the risk of failure due to external interference.

[0030] Furthermore, multiple groups of steel wires 5 and support pads 6 are arranged inside the metal conductor 1, and each group of steel wires 5 and support pads 6 are evenly spaced. Through the arrangement of the steel wires 5 and support pads 6, the steel wires 5 enhance the overall strength of the metal conductor 1, prevent the conductor from being easily deformed or broken when pulled or squeezed by external force, and improve the durability of the conductor. The evenly spaced support pads 6 make the supporting effect of the steel wires 5 more uniform, further enhancing the stability of the conductor.

[0031] Furthermore, the support pad 6 is made of rubber, which has good elasticity and wear resistance.

During the connection, the fixed block 1108 can be firmly inserted into the fixed hole 1109 under the action of the telescopic spring 1106, thereby ensuring the connection stability of the support mechanism 11.

[0036] Furthermore, the position of the fixing block 1108 corresponds to the position of the fixing hole 1109, and the outer wall size of the fixing block 1108 matches the inner wall size of the fixing hole 1109. By setting the fixing block 1108 and the fixing hole 1109, the fixing block 1108 and the fixing hole 1109 with corresponding positions and matching sizes ensure the connection accuracy of the support mechanism 11 and improve the installation quality. After the fixing block 1108 is inserted into the fixing hole 1109, it can effectively prevent the relative movement between the first support block 1101 and the second support block 1103, thereby enhancing the stability of the support mechanism 11.

[0037] Working principle: When the high-voltage connecting wire is put into use, the metal conductor 1 serves as the main power transmission channel. Since it is made of copper material and its conductivity is not less than 95% IACS, it can efficiently conduct current and reduce the loss of power during transmission. On the inner side of the metal conductor 1, multiple groups of steel wires 5 and support pads 6 cooperate with each other to provide internal support for the metal conductor 1. When the wire is pulled or squeezed by external force, the steel wire 5 enhances the overall strength of the metal conductor 1 with its high strength to prevent it from deformation or breakage. The support pads 6 distributed at equal intervals provide uniform support for the steel wire 5. At the same time, when the wire is impacted by external force, the rubber support pads 6 play a buffering role to reduce damage to the metal conductor 1, and its good wear resistance ensures long-term Stable supporting effect, the outside of the metal conductor 1 is covered with a first insulating layer 2, a shielding layer 3 and a second insulating layer 4 in sequence. The first insulating layer 2 and the second insulating layer 4 are mainly made of silicone, which provides double insulation protection for the wire, effectively prevents leakage and electric shock accidents, and improves safety in use. The shielding layer 3 is composed of aluminum foil, which can effectively shield external electromagnetic interference, reduce the impact of electromagnetic radiation on the surrounding environment and equipment, and reduce the risk of failure due to external interference. On the outside of the second insulating layer 4 is a sheath 7, and the inner surface of the sheath 7 is provided with an anti-corrosion layer 8, a high temperature resistant layer 9 and a wear-resistant layer 10. The epoxy resin coating of the anti-corrosion layer 8 can resist external corrosion factors, protect the wire from corrosion damage, extend the service life of the wire, and withstand high The ceramic fiber material of the temperature layer 9 enables the conductor to work normally in a high temperature environment and can withstand a temperature range of 800°C-1200°C, thereby avoiding degradation or damage to the conductor performance due to high temperature and improving the reliability of the conductor. The polytetrafluoroethylene material of the wear-resistant layer 10 protects the conductor from wear and reduces damage caused by friction, thereby improving the durability of the conductor. A supporting mechanism 11 is provided on the outer surface of the sheath 7. When the conductor needs to be supported and fixed, the first supporting block 1101 and the second supporting block 1103 are respectively approached from both sides of the sheath 7, and the clamping block 1104 at one end of the second supporting block 1103 is pushed toward the clamping groove 1102 on the inner surface of the first supporting block 1101. In the process of the clamping block 1104 entering the clamping groove 1102, the fixing block 11 08 is squeezed by the inner wall of the card slot 1102 and moves into the telescopic hole 1105, thereby pushing the limit plate 1107 to compress the telescopic spring 1106. When the card block 1104 completely enters the card slot 1102, the fixed block 1108 pops out under the elastic restoring force of the telescopic spring 1106, aligns with the fixed hole 1109 on the inner surface of the card slot 1102 and inserts into it, realizing the fixed connection between the first support block 1101 and the second support block 1103. At this time, the first support block 1101 and the second support block 1103, which are matched in size, fit tightly and surround the outer side of the sheath 7, providing rigid support for the entire high-voltage connecting wire, ensuring that the wire can maintain a fixed shape under various environments. When the wire is subjected to external pressure or vibration,The support mechanism 11 can protect the internal wire structure through its own structural strength and elastic buffer. The correspondingly positioned and sized card blocks 1104 and card slots 1102 ensure the connection accuracy and improve the installation efficiency. The telescopic structure formed by the limit plate 1107 through the telescopic spring 1106 and the fixed block 1108 makes the connection more convenient and quick, and ensures the connection stability of the support mechanism 11 after the connection. The correspondingly positioned and sized fixed blocks 1108 and fixed holes 1109 further improve the connection accuracy and stability of the support mechanism 11, and prevent the relative movement between the first support block 1101 and the second support block 1103, thus completing the use process of a high-voltage connection wire with a fixed shape and a shielding function.
