Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, and in particular to an insulating component for electrical engineering switch connections. Background Technology

[0002] In the field of electrical engineering, switch connection insulation components are key parts that ensure the safe and stable operation of electrical equipment, and their performance is of paramount importance.

[0003] Traditional insulating components often face numerous challenges during installation. For example, when an insulating component needs to be inserted into a channel with a certain amount of friction or moved to connect with other components, the sliding friction between the components generates significant resistance, making the installation process difficult and potentially causing wear on the insulating component and related components, affecting their service life and performance. Moreover, during equipment operation, factors such as vibrations generated by switching actions can cause unnecessary rotation or displacement of the insulating component, leading to unstable electrical connections, which in turn can cause safety hazards and equipment failures, greatly affecting the reliability and stability of the electrical system.

[0004] Therefore, we propose an insulating component for electrical engineering switch connections. Utility Model Content

[0005] The main purpose of this utility model is to provide an electrical engineering switch connection insulation component to prevent problems such as installation difficulties and component wear caused by sliding friction during installation, and the insulator rotating or displacing due to vibration during equipment operation, which can lead to unstable electrical connections, safety hazards, and equipment failures. This invention aims to improve the reliability and stability of electrical equipment and the service life and performance of the insulation component and related parts, and can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An electrical engineering switch connection insulation component includes an insulating sleeve with multiple outer rings arranged at equal intervals on the outside of the insulating sleeve. The outer rings have grooves on their outer walls and are circular ring structures. Multiple grooves are arranged in a ring array around the center of the outer rings. A connecting shaft is fixedly connected to each of the multiple grooves. Rollers are rotatably connected to the outer walls of the multiple connecting shafts. Multiple protrusions are provided on the outer walls of the outer rings, and the protrusions are located between adjacent grooves.

[0008] By adopting the above technical solution, when the insulating component comes into contact with other components or moves during installation, the roller on the outer ring plays a key role. The roller is connected to the groove on the outer ring through the connecting shaft and can rotate around the connecting shaft. For example, when the insulating component is inserted into a channel with a certain friction or when it moves relative to other surfaces, the roller will roll instead of slide. The friction of rolling friction is much smaller than that of sliding friction, which can reduce the resistance during installation or movement, so that the insulating component can be installed in the right position or connected with other components more smoothly.

[0009] The raised strips on the outer wall of the outer ring are located between adjacent grooves. These raised strips can play a role in positioning and increasing stability. When the insulating component is used with other components, the raised strips can be embedded into the corresponding grooves of other components or make close contact with the surfaces of other components, thereby preventing unnecessary rotation or displacement of the insulating component during operation. For example, when vibration is generated by switching action, the raised strips can keep the insulating component and adjacent components in a relatively fixed position, ensuring the stability of the electrical connection.

[0010] Furthermore, both the outer ring and the roller are made of plastic.

[0011] By adopting the above technical solution, since both the outer ring and the roller are made of plastic, and plastic is a good electrical insulator, in the scenario of electrical engineering switch connection, when current passes through the conductive part of the switch, this insulating material can effectively prevent current leakage to the outside. For example, in a high-voltage electrical switch device, even in a high-voltage environment, the plastic outer ring and roller can prevent current from being conducted from the internal conductive line to the outer casing or other grounded parts of the device, ensuring the safety of electrical equipment users and avoiding electric shock accidents caused by leakage.

[0012] Plastic materials have a certain degree of flexibility and wear resistance. For rollers, their wear resistance ensures that the rollers can still work normally after long-term use when they come into contact with and roll with other parts. For example, when the insulating parts are installed or when the switching action causes relative movement between them and the surrounding parts, the rollers will continuously come into contact with other surfaces and roll. Plastic rollers can withstand this friction, reduce wear, and thus maintain a low coefficient of rolling friction, allowing the insulating parts to move smoothly or cooperate with other parts.

[0013] For the outer ring, the flexibility of the plastic material allows it to withstand certain external forces, such as compression during installation or slight impacts in the working environment, without easily breaking. Furthermore, when combined with other components, it can better adapt to subtle differences in shape, ensuring the integrity of the entire insulation structure and the stability of its function.

[0014] Furthermore, the raised strip is made of rubber.

[0015] By adopting the above technical solution, rubber, a material with good elasticity, can buffer and dampen vibrations when the switch vibrates or is subjected to external impacts during operation. Simultaneously, the relatively rough surface of the rubber protrusion generates significant friction when in contact with mating components. This helps to further enhance the stability of the insulating component in its installation position. For example, when the insulating component is installed in a slot or other fixed structure, the protrusion is in close contact with the slot wall, and the friction prevents the insulating component from shifting due to external forces such as slight shaking during equipment operation.

[0016] Furthermore, both ends of the insulating sleeve are provided with interfaces.

[0017] By adopting the above technical solution, the interface design is intended to facilitate connection with components such as wires and switches.

[0018] Furthermore, the insulating sleeve is composed of an inner shielding layer, an insulating layer, and an outer shielding layer.

[0019] By adopting the above technical solution, the inner shielding layer mainly plays the role of uniform electric field. In electrical equipment, especially in high voltage environment, uneven electric field distribution may lead to problems such as partial discharge. The inner shielding layer can adjust the electric field distribution through its own good conductivity, usually semiconductor material.

[0020] The insulating layer is the core part of the entire insulating bushing, used to prevent current from passing through, and it is made of a material with high insulation properties.

[0021] The main function of the outer shielding layer is to shield external interference and protect the insulation layer from the influence of external environmental factors.

[0022] Furthermore, the insulating layer is located outside the inner shielding layer, and the outer shielding layer is located outside the insulating layer.

[0023] By adopting the above technical solution, this distribution structure of inner shielding layer, insulation layer and outer shielding layer forms an effective electric field control and insulation protection system, and this layered structure is a multi-layer protection mechanism.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) This utility model provides an electrical engineering switch connection insulation component. When the insulation component is installed, such as when it is inserted into a channel with friction or when it moves relative to other components during connection, the roller converts sliding friction into rolling friction by means of the rotational connection between the connecting shaft and the outer ring groove. Since the frictional force of rolling friction is much smaller than that of sliding friction, the resistance of the insulation component during installation or movement is greatly reduced, and it can reach the appropriate position more smoothly and complete the connection with other components, which greatly improves the installation efficiency, reduces the wear on the insulation component and related components, and extends the service life of the equipment.

[0026] (2) The present invention provides an electrical engineering switch connection insulation component. When the insulation component is used in conjunction with other components, the protrusion can be precisely embedded into the corresponding groove of other components or in close contact with the surface of other components. Under complex working conditions such as vibration caused by switch operation, the protrusion can effectively prevent unnecessary rotation or displacement of the insulation component, so that the insulation component and adjacent components always maintain a relatively fixed position, which effectively ensures the stability of the electrical connection, reduces the safety hazards and equipment failure probability caused by unstable connection, and provides a solid guarantee for the reliable operation of the electrical system.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] To prevent installation difficulties and component wear caused by excessive sliding friction during installation, and to prevent unstable electrical connections, safety hazards, and equipment failures due to vibration-induced rotation or displacement of insulation components during equipment operation, thereby improving the reliability, stability, and service life and performance of electrical equipment and related components, such as... Figure 1 , Figure 2 , Figure 3As shown, an electrical engineering switch connection insulation component includes an insulating sleeve 1. Multiple outer rings 2 are arranged equidistantly on the outside of the insulating sleeve 1. The outer rings 2 have grooves 3 on their outer walls. The outer rings 2 are circular ring structures. Multiple grooves 3 are arranged in a ring array around the center of the outer rings 2. A connecting shaft 4 is fixedly connected to each of the multiple grooves 3. Rollers 5 are rotatably connected to the outer walls of the multiple connecting shafts 4. Multiple protrusions 6 are provided on the outer walls of the outer rings 2. The protrusions 6 are located between adjacent grooves 3.

[0033] In use, when the insulating component comes into contact with other components or moves during installation, the roller 5 on the outer ring 2 plays a key role. The roller 5 is connected to the groove 3 on the outer ring 2 through the connecting shaft 4 and can rotate around the connecting shaft 4. For example, when the insulating component is inserted into a channel with a certain friction or when it has relative movement with other surfaces, the roller 5 will roll instead of slide. The friction of rolling friction is much smaller than that of sliding friction, which can reduce the resistance during installation or movement, so that the insulating component can be installed in the right position or connected with other components more smoothly.

[0034] The protrusions 6 on the outer wall of the outer ring 2 are located between adjacent grooves 3. These protrusions 6 can play a role in positioning and increasing stability. When the insulating component is in contact with other components, the protrusions 6 can be embedded into the corresponding grooves of other components or in close contact with the surfaces of other components, thereby preventing unnecessary rotation or displacement of the insulating component during operation. For example, when vibration is generated by switching action, the protrusions 6 can keep the insulating component and adjacent components in a relatively fixed position, ensuring the stability of the electrical connection.

[0035] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes that both the outer ring 2 and the roller 5 are made of plastic.

[0036] When in use, since both the outer ring 2 and the roller 5 are made of plastic, and plastic is a good electrical insulator, in the scenario of electrical engineering switch connection, when current passes through the conductive part of the switch, this insulating material can effectively prevent current leakage to the outside. For example, in a high-voltage electrical switch device, even in a high-voltage environment, the plastic outer ring 2 and roller 5 can prevent current from being conducted from the internal conductive line to the outer casing or other grounded parts of the device, ensuring the safety of electrical equipment users and avoiding electric shock accidents caused by leakage.

[0037] Plastic material has a certain degree of flexibility and wear resistance. For roller 5, its wear resistance can ensure that roller 5 can still work normally after long-term use when it comes into contact with and rolls with other parts. For example, when the insulating part is installed or when the switch action causes it to move relative to the surrounding parts, roller 5 will continuously come into contact with other surfaces and roll. The plastic roller 5 can withstand this friction, reduce wear, and thus maintain a low rolling friction coefficient, so that the insulating part can move smoothly or cooperate with other parts.

[0038] For the outer ring 2, the flexibility of the plastic material allows it to withstand certain external forces, such as being squeezed during installation or subjected to slight impacts in the working environment, without easily breaking. Furthermore, when combined with other components, it can better adapt to subtle differences in shape, ensuring the integrity of the entire insulation structure and the stability of its function.

[0039] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes that the protruding strip 6 is made of rubber.

[0040] In use, rubber is a material with good elasticity. When the switch vibrates or is subjected to external impact during operation, the raised strip 6 can act as a buffer and shock absorber. At the same time, the relatively rough surface of the rubber raised strip 6 can generate greater friction when in contact with mating parts. This helps to further enhance the stability of the insulating component in the installation position. For example, when the insulating component is installed in a slot or other fixed structure, the raised strip 6 is in close contact with the slot wall, and the friction can prevent the insulating component from being displaced due to external forces such as slight shaking during equipment operation.

[0041] For example, such as Figure 1 As shown, the present invention also includes an interface 7 provided at both ends of the insulating sleeve 1.

[0042] When in use, interface 7 is designed to facilitate connection with components such as wires and switches.

[0043] For example, such as Figure 3 As shown, the present invention also includes an insulating sleeve 1 composed of an inner shielding layer 8, an insulating layer 9, and an outer shielding layer 10.

[0044] When in use, the inner shielding layer 8 mainly serves to uniform the electric field. In electrical equipment, especially in high-voltage environments, uneven electric field distribution may lead to problems such as partial discharge. The inner shielding layer 8 can adjust the electric field distribution through its own good conductivity, usually a semiconductor material.

[0045] The insulating layer 9 is the core part of the entire insulating sleeve 1, used to prevent current from passing through, and it is made of a material with high insulation properties.

[0046] The main function of the outer shielding layer 10 is to shield external interference and protect the insulation layer 9 from external environmental factors.

[0047] For example, such as Figure 3 As shown, the present invention also includes an insulating layer 9 located outside the inner shielding layer 8, and an outer shielding layer 10 located outside the insulating layer 9.

[0048] When in use, the distribution structure of the inner shielding layer 8, the insulating layer 9, and the outer shielding layer 10 forms an effective electric field control and insulation protection system, and this layered structure is a multi-layer protection mechanism.

[0049] It should be noted that this utility model is an electrical engineering switch connection insulation component. First, based on the requirement of good insulation for electrical engineering switch connections, plastic is selected as the material for the outer ring 2 and the roller 5. This is because in the electrical environment, especially in switch connection parts, preventing current leakage is crucial. The insulation performance of plastic can ensure that under high voltage conditions, current is prevented from being conducted from the internal conductive lines to the outer casing or other grounded parts of the device. As for the roller 5, considering that it will frequently come into contact with other components during installation and switch operation, it needs to be wear-resistant. The wear resistance of plastic material can withstand this long-term friction, reduce wear, and maintain a low rolling friction coefficient to ensure that the insulation component can move smoothly or cooperate with other components.

[0050] For outer ring 2, since it may be squeezed during installation and may be subject to slight impact in the working environment, it needs to have a certain degree of flexibility. The flexibility of plastic can prevent it from breaking easily when subjected to external force and can better adapt to the slight differences in shape with other parts, ensuring the integrity of the insulation structure and the stability of its function.

[0051] Considering the potential for vibration or external impact during switch operation, rubber was chosen as the material for the protrusion 6. The good elasticity of rubber can buffer and dampen vibrations or impacts, protecting the insulating parts and connected components. At the same time, the relatively rough surface of the rubber material can generate greater friction when in contact with mating parts. This is very important for enhancing the stability of the insulating parts in the installation position. For example, when the insulating parts are installed in fixed structures such as slots, the protrusion 6 is in close contact with the slot wall, using friction to prevent the insulating parts from shifting due to external forces.

[0052] In high-voltage electrical equipment, in order to avoid problems such as partial discharge caused by uneven electric field distribution, a material with good conductivity, usually a semiconductor material, is selected as the inner shielding layer 8. Its main purpose is to adjust the electric field distribution through its own conductivity, so that the electric field is more evenly distributed on the side of the insulation layer 9 near the internal conductive part, thereby reducing the risk of partial discharge inside the insulation layer 9.

[0053] The insulation layer 9, as the core part that prevents current from passing through, is made of materials with high insulation properties, such as ceramics, rubber or high-performance plastics. These materials can withstand electric field forces and prevent the movement of electrons, thereby achieving electrical insulation and effectively isolating the internal high-voltage conductive parts from the external equipment casing or other grounded parts to prevent current leakage.

[0054] Considering the need to shield external interference and protect the insulation layer 9 from external environmental factors, the outer shielding layer 10 can be made of materials such as metal foil or conductive coating. For shielding external electromagnetic interference, these materials can effectively absorb or reflect external electromagnetic fields, ensuring the stability of the electric field inside the insulating sleeve 1. In terms of protecting against external environmental factors, such as blocking dust, moisture, and corrosive gases, these materials can protect the insulation layer 9 and extend its service life.
