Description

Technical Field

[0001] This utility model belongs to the field of conductor technology, and in particular relates to a high-temperature compensation conductor. Background Technology

[0002] A conductor is a wire made of metal or other materials that can conduct electric current. It is the most basic component of a circuit and is used to establish electrical connections, connecting power sources, electrical components, and loads, so that current can flow in the circuit. Conductors are usually made of materials with good conductivity, such as metals like copper and aluminum. These materials have a large number of freely moving electrons in their atomic structure.

[0003] High-temperature compensating wires are wires used to connect thermocouples to measuring devices. Their main function is to ensure that, within a certain temperature range, usually in a high-temperature environment, their thermoelectric characteristics are similar to those of the thermocouple they are connected to, so as to accurately transfer the thermoelectric potential generated by the thermocouple to the measuring instrument and ensure the accuracy of temperature measurement.

[0004] Currently, the existing high-temperature compensation wires have poor shielding. In industrial environments, there are many sources of electromagnetic interference, such as motors, transformers, and high-frequency communication equipment. When the shielding of the high-temperature compensation wires is not good, the external electromagnetic field will induce an electromotive force on the wires. These induced electromotive forces will be superimposed on the thermoelectric potential signal generated by the thermocouple, causing the measurement signal to deviate.

[0005] To address the aforementioned issues, this application proposes a high-temperature compensation conductor. Utility Model Content

[0006] The purpose of this invention is to provide a high-temperature compensation conductor that solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a high-temperature compensating conductor, comprising an outer protective sleeve, a shielding sliding sleeve slidably connected to the outer surface of the outer protective sleeve, two sliding shells fixedly connected to the outer surface of the outer protective sleeve, an extension sleeve slidably connected to the inner wall of each sliding shell, two telescopic frames fixedly connected to the inner wall of the outer protective sleeve, a shielding sleeve fixedly connected to the inner wall of the outer protective sleeve, the bottom surface of each telescopic frame contacting the outer surface of the shielding sleeve, a filling rubber and two limiting frames fixedly connected to the inner wall of the shielding sleeve, the left and right ends of the filling rubber being fixedly connected to the sides of the two limiting frames that are close to each other, two sets of shielding mesh sleeves being provided together by the two limiting frames and the inner wall of the filling rubber, and a wire core being provided inside each shielding mesh sleeve.

[0009] Furthermore, a reinforcing frame is fixedly connected to the outer surface of each telescopic frame, and the bottom surface of each reinforcing frame is fixedly connected to the outer surface of the shielding sleeve.

[0010] Furthermore, the two limiting frames and the inner walls of the rubber filling are jointly fixedly connected to two sets of fixing sleeves, and the inner wall of each fixing sleeve is fixedly connected to the outer surface of the shielding mesh sleeve.

[0011] Furthermore, the inner walls of the two limiting frames are jointly fixedly connected with three reinforcing lines, and the outer surface of each reinforcing line is fixedly connected to the inner wall filled with rubber.

[0012] Furthermore, an insulating sleeve is fixedly connected to the outer surface of each of the wire cores, and the outer surface of each insulating sleeve is fixedly connected to the inner wall of the shielding mesh sleeve.

[0013] Furthermore, a fixing block is fixedly connected to the upper surface of each of the extension sleeves, and an assist plate is fixedly connected to the upper surface of each of the fixing blocks.

[0014] Furthermore, a movable ring is fixedly connected to the outer surface of the shielding sliding sleeve, and the outer surface of the movable ring is provided with anti-slip holes arranged at equal intervals.

[0015] This utility model has the following beneficial effects:

[0016] This utility model, by incorporating a wire core, enables connection between thermocouples and measuring devices. Simultaneously, an outer protective sleeve protects and secures the shielding sleeve, filling rubber, shielding mesh sleeve, and wire core, ensuring stable operation. The shielding sleeve, made of metal-plated plastic, guarantees shielding performance while maintaining wire core flexibility. The filling rubber, made of silver-plated conductive rubber, possesses excellent conductivity and dispersion, forming a conductive network within the rubber to achieve electromagnetic shielding. Furthermore, the shielding mesh sleeve, made of woven metal, offers excellent flexibility and conductivity, effectively blocking external electromagnetic interference and significantly reducing its impact on measurement signals, thereby improving the wire core's performance.

[0017] This utility model, through the extension and retraction of the telescopic frame, allows for easy connection of the shielding sleeve to the ground, enabling interference current to be conducted to the earth through the grounding path. This prevents interference signals from circulating within the shielding sleeve and affecting the accuracy of the measurement signal. Simultaneously, the sliding shell, in conjunction with the extension and retraction of the extension sleeve, protects the connection points of the wire core, reducing the influence of external signals on the wire core. Furthermore, the sliding of the shielding sliding sleeve isolates the outer surface of the outer protective sleeve from the contact point with the interference device, further improving the stability of the wire core during use.

[0018] In summary, the wire cores can be connected and used, while the shielding sleeve can shield external signals. The shielding effect is enhanced by filling with rubber and using a shielding mesh sleeve. The telescopic frame allows the shielding sleeve to be grounded, enabling interference current to be conducted to the ground through the grounding path, thus improving the shielding effect. The sliding shell and the sliding extension sleeve can protect the connection points of the wire cores. At the same time, the shielding sliding sleeve can isolate the equipment from the outer protective sleeve, further enhancing the shielding performance of the wire cores during use and enabling the wire cores to stably transmit signals.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] Please see Figure 1-7 As shown, this utility model is a high-temperature compensation conductor, including an outer protective sleeve 1, a shielding sliding sleeve 2 slidably connected to the outer surface of the outer protective sleeve 1, two sliding shells 3 fixedly connected to the outer surface of the outer protective sleeve 1, an extension sleeve 4 slidably connected to the inner wall of each sliding shell 3, two telescopic frames 6 fixedly connected to the inner wall of the outer protective sleeve 1, a shielding sleeve 7 fixedly connected to the inner wall of the outer protective sleeve 1, the bottom surface of each telescopic frame 6 contacting the outer surface of the shielding sleeve 7, a filling rubber 8 and two limiting frames 5 fixedly connected to the inner wall of the shielding sleeve 7 respectively, the left and right ends of the filling rubber 8 being fixedly connected to the side of the two limiting frames 5 that are close to each other, the two limiting frames 5 and the inner wall of the filling rubber 8 are jointly provided with two sets of shielding mesh sleeves 11, and a wire core 12 is provided inside each shielding mesh sleeve 11. In this embodiment, the shielding sliding sleeve 2 and the sliding shell 3 are made of metal-ceramic composite material, which can withstand high temperatures while resisting the erosion of corrosive gases, and can effectively shield external electromagnetic interference.

[0033] Each telescopic frame 6 has a reinforcing frame 9 fixedly connected to its outer surface, and the bottom surface of each reinforcing frame 9 is fixedly connected to the outer surface of the shielding sleeve 7. In this embodiment, the reinforcing frame 9 can fix the telescopic frame 6 to the shielding sleeve 7, so that the telescopic frame 6 can be used stably.

[0034] Two sets of fixing sleeves 10 are fixedly connected to the inner walls of the two limiting frames 5 and the filling rubber 8. The inner wall of each fixing sleeve 10 is fixedly connected to the outer surface of the shielding mesh sleeve 11. In this embodiment, the fixing sleeves 10 can fix the shielding mesh sleeve 11 to the limiting frames 5 and the filling rubber 8, thereby protecting and fixing the shielding mesh sleeve 11.

[0035] In this embodiment, the inner walls of the two limiting frames 5 are jointly fixedly connected with three reinforcing wires 13. The outer surface of each reinforcing wire 13 is fixedly connected to the inner wall of the filling rubber 8. In this embodiment, the reinforcing wires 13 can be fixed with the limiting frames 5 and the filling rubber 8, thereby improving the overall strength of the conductor.

[0036] In this embodiment, an insulating sleeve 14 is fixedly connected to the outer surface of each wire core 12, and the outer surface of each insulating sleeve 14 is fixedly connected to the inner wall of the shielding mesh sleeve 11. In this embodiment, the insulating sleeve 14 can protect the wire core 12 inside, thereby enabling the overall wire to be used safely.

[0037] Each extension sleeve 4 has a fixed block 16 fixedly connected to its upper surface, and each fixed block 16 has an assist plate 15 fixedly connected to its upper surface. In this embodiment, the assist plate 15 can be fixed to the extension sleeve 4 by the fixed block 16, and the extension sleeve 4 can be slid easily by the assist plate 15.

[0038] The outer surface of the shielding sliding sleeve 2 is fixedly connected to a movable ring 17.

Furthermore, the telescopic frame 6, together with the sliding shell 3, the extension sleeve 4 and the shielding sliding sleeve 2, can isolate and protect the connection of the shielding sliding sleeve 2, further improving the overall shielding effect of the wire core 12 during use and enabling the wire core 12 to be used stably.

After the wire core 12 is laid, the telescopic frame 6 is extended and retracted so that the telescopic frame 6 contacts the ground. At the same time, the extension sleeve 4 is extended and retracted within the sliding shell 3 through the assist plate 15 and the fixing block 16, so that the extension sleeve 4 covers the connection of the wire core 12 inside, improving the shielding of the connection of the wire core 12. The shielding is slid by the moving ring 17 and the anti-slip hole 18. The sleeve 2 slides on the outer protective sleeve 1, and at the same time slides the shielding sliding sleeve 2 to the position where the outer protective sleeve 1 is connected to the equipment, so that the shielding sliding sleeve 2 isolates the outer protective sleeve 1 and the equipment, thereby reducing the interference of the equipment to the wire core 12. When the wire core 12 is in use, the shielding sleeve 7, together with the materials of the filling rubber 8 and the shielding mesh sleeve 11, shields the external electromagnetic interference. At the same time, the signal shielded by the shielding sleeve 7 is transmitted to the ground through the telescopic frame 6, further improving the shielding performance of the wire core 12 during use, so that the wire core 12 can be stably connected to the thermocouple and the measuring device.
