Description
Technical Field
[0001] The utility model specifically relates to a bakelite component of an electric appliance box. Background Art
[0002] Existing electric vehicles and motorcycles both need to be provided with an ignition switch, also known as an electric door lock. After the key is inserted into the electric door lock, it drives components such as the lock core to work, thereby starting the rotor switch. An electric appliance box bakelite component is arranged outside the rotor switch, and the electric appliance box bakelite component is connected with a conducting wire to achieve connection with the controller. In this way, the vehicle can be started.
[0003] Existing electric appliance box bakelite components usually have through connection holes, and conductive metal parts are installed in the connection holes. The end of the conducting wire is welded to the metal part. During this process, a flowing molten pool will be generated, and the molten pool will penetrate into the interior of the electric appliance box bakelite component along the connection hole, resulting in electrical breakdown or open circuit, greatly affecting the safety performance of the electric door lock. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide an electric appliance box bakelite component aiming at the deficiencies of the above-mentioned existing technology, and design a boss at the connection hole to prevent the molten pool from penetrating.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] An electric appliance box bakelite component, including a base, a through connection hole is arranged at the end of the base, and a conductive metal part is installed at the connection hole. It is characterized in that: a boss is connected to the upper end of the connection hole, the end face of the boss is higher than the end face of the base, and a first through hole communicating with the connection hole is penetrated through the middle of the boss.
[0007] By adopting the above technical solutions, by adding a boss at the upper end of the connection hole and the boss being higher than the end face of the base, the problem that the molten pool penetrates into the interior of the electric appliance box bakelite component along the connection hole is effectively avoided. This improvement not only prevents the occurrence of electrical breakdown or open circuit, but also improves the safety performance of the electric door lock. Specifically, the setting of the boss forms a physical partition to prevent the penetration of the molten pool during the welding process. The molten pool will flow to the outer periphery of the boss and will not directly penetrate along the connection hole, while the design of the first through hole ensures that the connection between the metal part and the end of the conducting wire will not be hindered, ensuring the working performance of the electric appliance box bakelite component. Among them, the metal part can be a conductive component such as a copper nail, etc., which is used for electrically connecting the wire with the working components inside the base.
[0008] The above-mentioned bakelite component of the electrical box can be further configured as follows: a circular flange is provided at the upper end of the metal part, the outer diameter of the circular flange is larger than the inner diameter of the connection hole, and after the metal part is installed in the connection hole, the circular flange contacts the end face of the boss.
[0009] With the above technical solution, by adding a circular flange at the upper end of the metal part and making its outer diameter larger than the inner diameter of the connection hole, when the metal part is installed, the circular flange contacts the end face of the boss. This design enhances the structural stability and sealing performance of the bakelite component of the electrical box. The circular flange forms a good sealing surface at the connection hole, preventing the penetration of the molten pool into the connection hole during welding, thereby effectively avoiding the risk of electrical breakdown or open circuit and improving the safety performance of the electric door lock.
[0010] The above-mentioned bakelite component of the electrical box can be further configured as follows: the boss is in the shape of a truncated cone, and the large end of the boss is connected to the end face of the base. An annular groove is provided on the end face of the boss at the small end, and the annular groove is distributed on the outer periphery of the first through hole.
[0011] With the above technical solution, firstly, the boss in the shape of a truncated cone can provide better structural stability. Its large end is connected to the end face of the base, enhancing the overall firmness. Secondly, the annular groove design at the small end of the boss surrounds the outer periphery of the first through hole. This layout helps to disperse the welding stress, reduce the thermal influence on the bakelite component of the electrical box during the welding process, and thus reduce the risk of welding deformation. At the same time, the presence of the annular groove also helps to collect the molten pool penetrant and prevent it from further spreading into the interior of the bakelite component of the electrical box, improving the electrical safety.
[0012] The above-mentioned bakelite component of the electrical box can be further configured as follows: a counterbore is provided at the lower end of the connection hole, the inner diameter of the counterbore is larger than the inner diameter of the connection hole, and a cylindrical flange seat adapted to the counterbore is provided at the lower end of the metal part.
[0013] With the above technical solution, the design of the counterbore enables the metal part to be more stably installed in the hole, avoiding excessive upward movement of the metal part when the wire is welded to the metal part.
[0014] The above-mentioned bakelite component of the electrical box can be further configured as follows: a counterbore is provided at the upper end of the metal part, and the inner peripheral surface of the counterbore is arc-shaped.
[0015] With the above technical solution, the design of the counterbore allows the metal part to fit tightly with the connection hole of the bakelite component after installation. Its arc-shaped inner peripheral surface helps to disperse the stress generated during welding or fastening, enabling the circular flange to undergo slight deformation, thereby reducing damage to the metal part and the conductive wire.
[0016] The above-mentioned bakelite component of the electrical box can be further configured as follows: the base includes a mounting frame and a fixing plate. An accommodation cavity is provided inside the mounting frame, and the upper end of the accommodation cavity is open. The fixing plate is distributed at the open end of the accommodation cavity. A plurality of groups of insertion plates are provided on the outer periphery of the fixing plate, and a set of insertion holes are respectively provided on the mounting frame corresponding to each group of insertion plates. An inclined surface is provided at the lower end of the insertion plate; the connection holes are distributed on the fixing plate.
[0017] Adopting the above technical solution, splitting the base into a split form of a mounting frame and a fixing plate can improve the assembly efficiency of the bakelite component of the electrical box and facilitate the installation of working components such as a rotor switch into the accommodation cavity. The setting of the fixing plate ensures the stability of the connection holes, and the cooperation with the insertion plates and insertion holes provides a fast and stable assembly method, facilitating the detachable connection between the fixing plate and the mounting frame.
[0018] The above-mentioned bakelite component of the electrical box can be further configured as follows: a plurality of groups of fan-shaped strip holes are provided on the upper end surface of the fixing plate, a convex block is further provided on the upper end surface of the fixing plate, and a second through hole penetrates through the middle of the fixing plate.
[0019] Adopting the above technical solution, designing the fan-shaped strip holes can reduce the overall weight of the bakelite component of the electrical box and facilitate the processing of markings. Processing the markings in the fan-shaped strip holes will neither make the surface of the fixing plate uneven nor is it simple and beautiful. At the same time, designing the second through hole facilitates the working components to pass through. Designing the convex block provides installation guidance and is convenient for disassembly and assembly.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0026] As Figures 1 to 3 shown in the bakelite assembly of the electrical box, it includes a base. A through connection hole 3 is provided at the end of the base. A conductive metal part 4 is installed at the connection hole 3. A boss 5 is connected to the upper end of the connection hole 3. The end face of the boss 5 is higher than the end face of the base, and a first through hole that is conductively connected to the connection hole 3 runs through the middle of the boss 5. By adding the boss 5 at the upper end of the connection hole 3 and making the boss 5 higher than the end face of the base, the problem that the molten pool penetrates into the interior of the bakelite assembly of the electrical box along the connection hole 3 is effectively avoided. This improvement not only prevents the occurrence of electrical breakdown or open circuit, but also improves the safety performance of the electric door lock. Specifically, the setting of the boss 5 forms a physical partition that prevents the penetration of the molten pool during the welding process. The molten pool will flow to the outer periphery of the boss 5 and will not directly penetrate along the connection hole 3. The design of the first through hole ensures that the connection between the metal part 4 and the end of the wire will not be hindered, ensuring the working performance of the bakelite assembly of the electrical box. Among them, the metal part 4 can be a conductive component such as a copper nail, which is used to electrically connect the wire to the working components inside the base.
[0027] A circular flange 6 is provided at the upper end of the metal part 4. The outer diameter of the circular flange 6 is larger than the inner diameter of the connection hole 3. After the metal part 4 is installed in the connection hole 3, the circular flange 6 contacts the end face of the boss 5. By adding the circular flange 6 at the upper end of the metal part 4 and making its outer diameter larger than the inner diameter of the connection hole 3, when the metal part 4 is installed, the circular flange 6 contacts the end face of the boss 5. This design enhances the structural stability and sealing performance of the bakelite assembly of the electrical box. The circular flange 6 forms a good sealing surface at the connection hole 3, preventing the molten pool from penetrating into the connection hole 3 during welding, thus effectively avoiding the risk of electrical breakdown or open circuit and improving the safety performance of the electric door lock.
[0028] The boss 5 is in the shape of a truncated cone, and the large end of the boss 5 is connected to the end face of the base. An annular groove 7 is provided on the end face of the small end of the boss 5, and the annular groove 7 is distributed on the outer periphery of the first through hole. First of all, the boss 5 in the shape of a truncated cone can provide better structural stability. Its large end is connected to the end face of the base, enhancing the overall firmness. Secondly, the annular groove 7 at the small end of the boss 5 is designed to surround the outer periphery of the first through hole. This layout helps to disperse the welding stress, reduce the thermal influence on the bakelite component of the electrical box during the welding process, and thus reduce the risk of welding deformation. At the same time, the existence of the annular groove 7 also helps to collect the molten pool penetrant, prevent it from further spreading into the interior of the bakelite component of the electrical box, and improve the electrical safety.
[0029] A counterbore 8 is provided at the lower end of the connecting hole 3. The inner diameter of the counterbore 8 is larger than the inner diameter of the connecting hole 3.

[0030] A counterbore 10 is provided at the upper end of the metal part 4, and the inner peripheral surface of the counterbore 10 is arc-shaped. The design of the counterbore 10 allows the metal part 4 to be closely fitted with the connecting hole 3 of the bakelite component after installation. Its arc-shaped inner peripheral surface helps to disperse the stress generated during welding or fastening, enabling the circular flange edge 6 to undergo slight deformation, thereby reducing damage to the metal part 4 and the conducting wire.
[0031] The base includes a mounting frame 1 and a fixing plate 2. A receiving cavity 11 is provided inside the mounting frame 1. The upper end of the receiving cavity 11 is open.
