Description

TECHNICAL FIELD

[0001] The utility model relates to conductor technical field, especially a kind of high-temperature-resistant conductor assembly. BACKGROUND

[0002] High-temperature-resistant conductor assembly is a kind of key components for stable transmission of electric energy or signal in high-temperature environment, and is widely used in aerospace, energy, metallurgy and electronic industry fields. Traditional conductor assembly often faces the problems of low heat dissipation efficiency and inconvenient connection in high-temperature environment. First, the heat generated by the conductor in high-temperature environment is difficult to dissipate quickly, which can easily lead to material performance degradation and even cause safety hazards. Secondly, the existing conductor connection method usually uses bolt fixing or welding, which is complex to operate and difficult to meet the needs of frequent disassembly, especially in high-temperature environment, the connection stability is poor.

[0003] To solve the above problems, the existing technology usually uses high-thermal-conductivity materials or increases the heat dissipation structure to improve the heat dissipation efficiency, such as coating a thermal conductive coating on the surface of the conductor or setting a heat dissipation fin. However, these methods often have limited heat dissipation effect and increase the complexity of the structure. In terms of connection method, the existing technology relies on traditional mechanical connection and lacks a quick and reliable docking solution, which is difficult to meet the needs of efficient operation in high-temperature environment.

[0004] To solve the above problems, the utility model provides a high-temperature-resistant conductor assembly. UTILITY MODEL CONTENTS

[0005] To solve the problems in the background art, the utility model provides a high-temperature-resistant conductor assembly.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a high-temperature-resistant conductor assembly, comprising a conductor core, an inner protective layer, an outer protective layer, and a spiral heat dissipation fin. The inner protective layer is sleeved on the outside of the conductor core, the outer protective layer is sleeved on the outside of the inner protective layer, the outer wall of the outer protective layer is fixedly installed with the spiral heat dissipation fin, and the surface of the spiral heat dissipation fin is coated with a high-temperature-resistant and oxidation-resistant coating. One end of the inner protective layer and the outer protective layer is fixedly installed with a connecting seat. The other end of the inner protective layer and the outer protective layer is fixedly installed with a tapered plug, and the two ends of the conductor core respectively extend to the inside of the connecting seat and the tapered plug, and the connecting seat and the tapered plug are limitingly inserted and connected.

[0007] The utility model is further provided with a plurality of protective strips fixedly installed on the inner wall of the inner protective layer around the axis of the conductor core, and the plurality of protective strips are tightly attached to the outer wall of the conductor core.

[0008] This invention is further configured such that both the inner protective layer and the protective strip are made of graphene or aluminum-based composite materials, facilitating rapid heat conduction. The protective strip is evenly distributed and tightly fitted to the conductor core, effectively dispersing the mechanical stress of the conductor core and preventing deformation or breakage under high load or vibration conditions. Simultaneously, the tight fit enhances the heat conduction efficiency between the conductor core and the inner protective layer, aiding in rapid heat dissipation and extending the service life of the conductor assembly.

[0009] The present invention is further configured such that a connecting ring is fixedly installed inside the connecting seat. One end of the conductor core extends into the interior of the connecting ring, and a limiting cavity is formed between the outer wall of the connecting ring and the inner wall of the connecting seat. A plug tube is fixedly installed on the tapered plug. The plug tube is inserted into the limiting cavity for limiting.

[0010] This invention is further configured such that limit rods are slidably installed on both the upper and lower sides of the connecting seat. The bottom end of the limit rod is beveled, and limit grooves are formed on both the upper and lower sides of the outer wall of the insertion tube. The limit rods and limit grooves are inserted into each other, and a spring is fixedly connected to the end of the limit rod away from the limit groove. The other end of the spring is fixedly connected to the outer wall of the connecting seat, and the spring is sleeved on the outside of the limit rod. The design of the connecting ring and the limit cavity realizes the precise docking of the conductor core and the insertion tube, ensuring the stability and reliability of the electrical connection. The insertion structure of the limit cavity can effectively prevent the insertion tube from loosening under vibration or thermal expansion and contraction, reduce contact resistance, and improve the electrical performance of the conductor assembly.

[0011] This invention is further configured such that a tapered opening is formed at the end of the inner wall of the connector that is away from the inner and outer protective layers. The tapered opening mates with the outer wall of the tapered plug. This mating design between the tapered opening and the tapered plug ensures precise alignment between the connector and the plug, guaranteeing the stability and sealing of the electrical connection. The tapered structure effectively disperses mechanical stress during insertion and reduces wear during insertion and removal.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This high-temperature resistant conductor assembly features a spiral heat dissipation fin, a connector, a tapered plug, a connector tube, a limiting cavity, and a limiting rod. The spiral structure of the spiral heat dissipation fin guides natural airflow convection, increases the heat dissipation surface area, and enhances the heat dissipation effect. A spring returns the fin to its original shape, causing the limiting rod to automatically enter the limiting groove, thereby limiting the connector tube. At the same time, the conductor cores of the two conductors contact and fit tightly inside the tapered plug, achieving rapid connection of the conductors. Attached Figure Description

[0026] Multiple protective strips 7 are uniformly fixedly installed on the inner wall of the inner protective layer 2 around the axis of the conductor core 1, and the multiple protective strips 7 are all tightly attached to the outer wall of the conductor core 1. Both the inner protective layer 2 and the protective strips 7 are made of graphene or aluminum-based composite materials, which facilitates rapid heat conduction.

[0027] A connecting ring 9 is fixedly installed inside the connecting seat 5. One end of the conductor core 1 extends into the connecting ring 9. A limiting cavity 11 is formed between the outer wall of the connecting ring 9 and the inner wall of the connecting seat 5. A plug tube 10 is fixedly installed on the tapered plug 6. The plug tube 10 is inserted into the limiting cavity 11. Limiting rods 12 are slidably installed on both the upper and lower sides of the connecting seat 5. The bottom end of the limiting rod 12 is set with a slope. Limiting grooves 13 are formed on both the upper and lower sides of the outer wall of the plug tube 10.

Through the cooperation between the plug tube 10 and the inclined surface at the bottom of the limiting rod 12, the limiting rod 12 is pushed away from the plug tube 10 and the spring 14 is extended. When the limiting groove 13 on the plug tube 10 moves to the bottom of the limiting rod 12, the spring 14 returns to its original state, causing the limiting rod 12 to automatically enter the limiting groove 13, thereby limiting the plug tube 10. At the same time, the conductor cores 1 of the two conductors contact and fit tightly inside the tapered plug 6, realizing the rapid connection of the conductors. When it is necessary to disconnect the conductors, the corresponding limiting rod 12 is pulled, causing the limiting rod 12 to disengage from the limiting groove 13, thereby releasing the limitation on the plug tube 10 and separating the two conductors.
