Description

Technical Field

[0001] This utility model relates to the field of integrated sealed copper busbar assemblies, and more specifically, to an integrated sealed copper busbar assembly. Background Technology

[0002] Copper busbars are high-current conductive products suitable for electrical engineering applications such as high and low voltage electrical appliances, switch contacts, power distribution equipment, and busbar trunking. They are also widely used in ultra-high current electrolytic smelting projects such as metal smelting, electroplating, and chemical caustic soda production. In circuits, they serve to transmit current and connect electrical equipment. Many electrical components need to be connected through copper busbars to form an electrical connection. However, the existing connection points between copper busbars and electrical components are only covered by insulating protective sleeves, which only provide insulation protection and cannot meet the waterproof and dustproof sealing requirements of the connection points. Moreover, many large power components need to operate in harsh environments for a long time, requiring even higher waterproof performance.

[0003] In the prior art, such as application publication number CN115663520A, this invention relates to the field of electronic connectors and provides a waterproof and sealed copper busbar connector and wiring assembly, including a copper busbar body and an integrally injection-molded plastic body. The plastic body has a first end face and a second end face, with one end of the copper busbar body extending through the first end face and the other end extending through the second end face. The plastic body is provided with a plurality of connection holes with sealing bushings, and a waterproof sealing ring is provided on the first end face. A first plastic sleeve is integrally molded on the first end face side of the plastic body and fitted onto one end of the copper busbar body, with waterproof adhesive between the first plastic sleeve and the copper busbar body. A second plastic sleeve is integrally molded on the second end face side of the plastic body and fitted onto the other end of the copper busbar body. The waterproof and sealed copper busbar connector and wiring assembly provided by this invention, with an integrally injection-molded plastic body, has good waterproof and dustproof effects and excellent sealing performance.

[0004] In the aforementioned patent, the sealing method uses multiple points of fixation, resulting in too many gaps that make it easy for water to leak in, thus leading to poor sealing performance. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an integrated sealed copper busbar assembly. By adopting an upper and lower combined fixing structure, a sealing concave cover main structure is then snapped into the end face of the power connection end for sealing and fixing. The inner protrusion is snapped into the connection for sealing, resulting in a small gap closure and improved sealing performance.

[0006] To solve the above problems, the present invention adopts the following technical solution.

The end faces of the first and second insulating shells are pressed and fitted together. The inner surfaces of the first and second insulating shells are provided with positioning grooves. A copper busbar is clamped and fixed to the inner surfaces of the positioning grooves of the first and second insulating shells. Electrical terminals are provided on the outer surfaces of the left and right ends of the copper busbar. Rubber rings are sleeved on the inner and outer surfaces of the electrical terminals. The outer surfaces of the rubber rings are snapped into the inner surfaces of the positioning grooves of the first and second insulating shells. Sealing concave cover bodies are snapped into the outer surfaces of the left and right sides of the first and second insulating shells. By adopting an upper and lower combined fixing structure, the sealing concave cover body structure is then snapped into the end face of the electrical terminal, which seals and fixes the connection. The inner protrusion is snapped into the connection to seal, resulting in a small gap and improved sealing performance.

[0008] Furthermore, the surface of the sealing recess body is provided with a square socket, and the inner surface of the square socket is slidably sleeved on the outer surface of the electrical terminal.

[0009] Furthermore, the inner end surface of the square insertion port of the sealing concave cover body is provided with an inner protrusion, and an inclined cut is provided outside the inner protrusion. The outer surface of the inner protrusion is tightly engaged with the inner side surface of the outer end of the first insulating sealing shell and the second insulating sealing shell.

[0010] Furthermore, the outer end surfaces of the first and second insulating sealing shells are provided with concave annular grooves, and the outer surface of the inner convex opening is tightly engaged with the inner surface of the concave annular groove.

[0011] Furthermore, the inner surface of the sealing recess body is covered with a rubber layer.

[0012] Furthermore, the first insulating enclosure is fixed to the upper surface of the second insulating enclosure by first screws, with three sets of first screws arranged in a row, and the left and right rows distributed on the surface of the first insulating enclosure.

[0013] Furthermore, the inner surfaces of the positioning grooves of the first and second insulating sealing shells are coated with a rubber layer, and the sealing concave cover body is fixedly connected to the outer end surfaces of the first and second insulating sealing shells by a second screw.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) By adopting an upper and lower combined fixed structure, the main structure of the sealing concave cover is installed in a snap-fit ​​type at the end face of the power connection end. The sealing and fixing are achieved by snapping the connection at the inner protrusion, resulting in a small gap closure and improved sealing performance. Attached Figure Description
