Description

Technical Field

[0001] This utility model relates to the field of insulating connectors, and in particular to wear-resistant ceramic insulating connectors. Background Technology

[0002] Insulating connectors are components used in electrical equipment to provide electrical insulation and achieve mechanical connection. Their main function is to prevent current from flowing where it is not needed, thereby protecting the equipment and the safety of operators. Insulating connectors are widely used in many fields such as power, communications, electronics, and machinery.

[0003] A search revealed that existing Chinese patent publication number "CN221508509U" provides an insulating connector, comprising: a metal radiator a, an insulating sheet between the metal radiator a and a metal radiator b, and a connector disposed on the surface of the insulating sheet away from the metal radiator a. A nut is embedded inside the connector, and a screw is screwed into the nut. This insulating connector's structure allows for both tight attachment between the metal radiators a and b, and ensures safe insulation between the nut and the metal radiator b. The embedded nut and its fit with the metal radiator b facilitate assembly when the screw is engaged, eliminating the need for specific positioning fixtures. The connector is integrally molded, has a simple structure, and occupies little space.

[0004] Currently, in some power production industries, the use of equipment results in the connection of multiple lines. Some of these lines are even multi-segment connections. The joints are connected to adjacent conductors using insulating components. However, these insulating components are mostly made of plastic. When the conductors are thick and the operating time is long, the plastic connectors are prone to aging, causing poor contact or leakage. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a wear-resistant ceramic insulating connector.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The design includes a wear-resistant ceramic insulating connector, comprising an insulating base, an internal groove at the center of the insulating base, and through holes on both sides of the insulating base, which are connected to the internal groove. A sealing plate is provided on the insulating base, covering the opening of the internal groove. A pull head is provided at the upper end of the sealing plate, and the pull head and the sealing plate are integrally formed.

[0008] The built-in slot is equipped with a power socket, which is fixed to the bottom of the built-in slot by screws. Power sockets are provided on both sides of the power socket. A threaded sleeve is provided through the upper end of the power socket. The connection between the threaded sleeve and the power socket is fixed by welding. A threaded knob is provided through the threaded sleeve. The outer threaded surface of the threaded knob and the inner threaded surface of the threaded sleeve are threaded together. A pressure plate is fixed to one end of the threaded knob inside the power socket. The power socket is made of copper alloy material.

[0009] In detail, the upper end of the insulating base is provided with a slot, and the lower end of the sealing plate is fixed with an elastic clip, which is engaged with the inside of the slot.

[0010] In detail, the elastic card is made of rubber material, and the shape of the elastic card and the inner shape of the card slot are both regular hexagons.

[0011] In detail, the insulating base includes a base layer, a buffer layer, a corrosion-resistant layer, and a wear-resistant layer. The base layer is coated with a buffer layer, the buffer layer is coated with a corrosion-resistant layer, and the corrosion-resistant layer is coated with a wear-resistant layer. The insulating base has the same material composition as the sealing plate, the pull head, the threaded knob, and the pressure plate.

[0012] In detail, the base layer is made of ceramic material.

[0013] In detail, the buffer layer is made of a polyurethane coating material.

[0014] In detail, the corrosion-resistant layer is made of phenolic resin coating material.

[0015] In detail, the wear-resistant layer is made of epoxy resin coating material.

[0016] The design scheme proposed in this utility model has the following beneficial effects in application:

[0017] 1. When connecting adjacent wires, first place the power socket in the built-in groove of the insulating base. The power socket can be fixed to the built-in groove with screws, so that the power socket can correspond to the position of the wire hole. Then, insert any wire through the wire hole on one side, so that the wire core is placed in the power socket. Then, turn the threaded knob so that the threaded knob and the threaded sleeve move with each other, so that the pressure plate and the wire core can be contacted and squeezed, thereby fixing the wire to the power socket. Through the connection of the wires on both sides and the power socket's power transition connection, the power supply stability after the line is connected can be ensured. Then, cover the sealing plate and the insulating base, and fix the sealing plate and the insulating base by snapping it into the slot with the elastic clip. This can provide all-round insulation protection for the power socket in the built-in groove.

[0018] 2. In order to further improve the performance of the insulating base in extreme environments, the insulating base is based on a ceramic material base. A polyurethane coating is first applied to the outside of the base to provide buffer protection. Then, a phenolic resin coating is applied to the outside of the polyurethane coating to provide acid and alkali corrosion resistance. Finally, an epoxy resin coating is applied to the outside of the phenolic resin coating to provide wear resistance and auxiliary corrosion resistance. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-4 Wear-resistant ceramic insulating connector, including insulating base 1, with an internal groove 11 at the center of insulating base 1, and through holes 12 on both sides of insulating base 1, which are connected to the internal groove 11. A sealing plate 13 is provided on insulating base 1, covering the groove opening of internal groove 11. A pull head 14 is provided at the upper end of sealing plate 13, and the pull head 14 and sealing plate 13 are integrally formed. After the wire passes through the through hole 12, in order to further ensure the sealing effect between the wire and the through hole 12, resin glue is filled for auxiliary sealing.

[0026] An electrical socket 15 is provided inside the built-in slot 11. The electrical socket 15 is fixed to the bottom of the built-in slot 11 by screws. Electrical slots 16 are provided on both sides of the electrical socket 15. A threaded sleeve 17 is provided through the upper end of the electrical slot 16. The connection between the threaded sleeve 17 and the electrical socket 15 is fixed by welding. A threaded knob 18 is provided through the threaded sleeve 17. The external thread surface of the threaded knob 18 and the internal thread surface of the threaded sleeve 17 are threaded together. A wire pressure plate 19 is fixed at one end of the threaded knob 18 inside the electrical slot 16. The electrical socket 15 is made of copper alloy material.

[0027] It should be further noted that the upper end of the insulating base 1 is provided with a slot 2, and the lower end of the sealing plate 13 is fixed with an elastic clip 21. The elastic clip 21 and the slot 2 are interlocked, which facilitates the assembly and disassembly of the sealing plate 13 and the insulating base 1.

[0028] It should be further noted that the elastic card 21 is made of rubber material, and the shape of the elastic card 21 and the inner shape of the slot 2 are both regular hexagons, which can ensure the stability of the engagement between the elastic card 21 and the slot 2 and the ease of disassembly.

[0029] It should be further explained that the insulating base 1 includes a base layer 1001, a buffer layer 1002, a corrosion-resistant layer 1003, and a wear-resistant layer 1004. The base layer 1001 is coated with a buffer layer 1002, the buffer layer 1002 is coated with a corrosion-resistant layer 1003, and the corrosion-resistant layer 1003 is coated with a wear-resistant layer 1004. The insulating base 1 is made of the same material as the sealing plate 13, the pull head 14, the threaded knob 18, and the pressure plate 19. Through the combination of multiple layers of materials, the insulating base 1 and other components made of the same material can be improved to have good insulation, corrosion resistance, and wear resistance.

[0030] It should be further noted that the base layer 1001 is made of ceramic material. Ceramic materials typically have very high hardness and wear resistance, making them excellent in applications requiring extremely high wear resistance. Ceramic materials can remain stable at extremely high temperatures without melting or deforming. Ceramic materials have high corrosion resistance to most chemicals, making them suitable for applications in corrosive environments. Ceramic materials are generally good electrical insulators, making them suitable for applications requiring electrical insulation.

[0031] It should be further noted that the buffer layer 1002 is made of polyurethane coating material. Polyurethane coating has good flexibility and elasticity, and can remain intact when subjected to impact or bending. It is suitable for surfaces that need to resist mechanical impact. Polyurethane coating has good resistance to many chemicals (such as acids, alkalis and solvents), and is suitable for protection in corrosive environments. Polyurethane coating can adhere well to a variety of substrates, such as metal, concrete and wood, to ensure the durability and effectiveness of the coating.

[0032] It should be further noted that the corrosion-resistant layer 1003 is made of phenolic resin coating material. Phenolic resin can maintain stable performance in high-temperature environments, with a maximum operating temperature of over 200℃, making it suitable for applications in high-temperature environments. Phenolic resin has good resistance to many chemicals (such as acids, alkalis, and solvents), making it suitable for protection in corrosive environments. Phenolic resin has good electrical insulation properties, making it suitable as an insulating material in electronic and electrical equipment. Phenolic resin has good flame retardant properties, is not easily combustible, and is suitable for occasions requiring fire protection.

[0033] It should be further noted that the wear-resistant layer 1004 is made of epoxy resin coating material. Epoxy resin coating has high strength and hardness, can withstand large mechanical loads, and is suitable for manufacturing high-strength parts. Epoxy resin coating has good wear resistance and impact resistance, can effectively resist mechanical wear and impact, and extend the service life of the protected material. Epoxy resin coating has good electrical insulation properties and is suitable for insulating materials in electronic and electrical equipment.

[0034] Working method: When it is necessary to connect adjacent wires, first place the power supply base 15 in the built-in groove 11 of the insulating base 1. The power supply base 15 and the built-in groove 11 can be fixed by screws, so that the power supply groove 16 can correspond to the position of the wire hole 12. Then, insert any wire through the wire hole 12 on one side, so that the wire core is placed in the power supply groove 16. Then, rotate the threaded knob 18, so that the threaded knob 18 and the threaded sleeve 17 move in relation to each other, so as to achieve contact and compression between the pressure plate 19 and the wire core, thereby fixing the wire to the power supply base 15. Through the connection of the wires on both sides and the power supply base 15, the power supply stability after the line is connected can be guaranteed. Then, cover the insulating base 1 with the sealing plate 13 and fix the sealing plate 13 to the insulating base 1 by inserting the elastic clip 21 into the clip slot 2. This can provide all-round insulation protection for the power supply base 15 in the built-in groove 11.

[0035] To further improve the performance of the insulating base 1 in extreme environments, the insulating base 1 is based on a ceramic base 1001. A polyurethane coating is first applied to the outside of the base 1001 to provide buffer protection. Then, a phenolic resin coating is applied to the outside of the polyurethane coating to provide acid and alkali corrosion resistance. Finally, an epoxy resin coating is applied to the outside of the phenolic resin coating to provide wear resistance and additional corrosion resistance.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
