Abstract
Description
Technical Field
[0001] This utility model relates to rail vehicle manufacturing technology, specifically to a current collector insulating base. Background Technology
[0002] Current collector insulators are commonly used in the traction systems of urban rail transit vehicles. Their main function is to ensure insulation between the current-carrying current collector and the bogie or other components, while also supporting other components of the current collector. By providing insulation, current collector insulators help prevent current leakage or short circuits, thus ensuring the safety and reliability of power transmission. Current collector insulators typically consist of a base plate and multiple partitions mounted on the base plate, dividing the insulating base plate into different areas. In existing technologies, the partitions and base plate are usually bonded with adhesive. While adhesive bonding can meet the insulation and fixation requirements to a certain extent, this method also has some potential drawbacks. For example, the adhesive bonding strength may be affected by environmental factors such as time, temperature, and humidity, leading to a decrease in bonding effectiveness and even the possibility of partition detachment. Furthermore, the adhesive bonding process is relatively complex, requiring strict control of the type, amount, and curing conditions of the adhesive to ensure bonding quality and production efficiency. In addition, the through-holes in the base plate in existing technologies may also pose a significant risk to insulation performance. Over time, these connection holes may become less insulating due to the intrusion of external factors such as rain and dust, posing a potential threat to the safety and reliability of power transmission. Summary of the Invention
[0003] To address the problems existing in the prior art, a current collector insulating base is provided to improve the overall strength and insulation performance of the current collector insulating base.
[0004] The technical solution adopted by this utility model is as follows: a current collector insulating base includes a base plate and a surrounding plate and an ear plate connected to the base plate. The surrounding plate is U-shaped and is set on the upper end surface of the base plate. A current collector mounting area is formed on the inner side of the surrounding plate. Two ear plates are respectively set at both ends of the base plate. The base plate, surrounding plate and ear plates are molded in one piece using SMC material. Multiple blind holes are provided on the base plate of the current collector mounting area. A metal connecting sleeve with internal thread is pre-embedded in the blind holes. A through fixing hole is opened on the ear plate.
[0005] Furthermore, a metal bushing is embedded in the fixing hole.
[0006] Furthermore, positioning pins are pre-embedded in the base plate of the current receiver installation area.
[0007] Furthermore, a reinforcing rib is provided between the surrounding plate and the ear plate, and the reinforcing rib is integrally formed with the bottom plate, the surrounding plate, and the ear plate.
[0008] The beneficial effects of this utility model are as follows: The current collector insulating base of this utility model is molded from SMC material in one piece, which significantly improves the overall structural strength of the insulating base, ensuring its stability and durability during use. This not only improves production efficiency but also reduces manufacturing costs. By designing multiple blind holes on the base plate of the current collector mounting area, and pre-embedding metal connecting sleeves with internal threads in these blind holes, a convenient interface is provided for the installation and fixing of the current collector. The blind holes completely isolate the possibility of current passing through the holes, effectively preventing current leakage and the intrusion of external factors, ensuring the insulation performance of the insulating base, and improving the overall safety of the equipment. By embedding metal nests in the fixing holes of the ear plate, the strength of the material around the fixing holes can be significantly improved, thereby significantly increasing the load-bearing capacity, as well as the compressive and shear resistance at the mounting bolt positions.
