Description

Technical Field

[0001] This utility model relates to the field of copper busbar installation technology, and in particular to a protective structure for copper busbar installation. 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. Electrical copper busbars have advantages such as low resistivity and high bendability. Also known as copper busbars, copper busbars, copper busbars, or grounding copper busbars, they are long conductors made of copper with a rectangular or chamfered rectangular cross-section, serving to transmit current and connect electrical equipment in circuits.

[0003] Many control cabinets and electrical cabinets have copper busbars extending from inside the enclosure to connect with external cables. Inevitably, these copper busbars will pass through the metal outer casing. To prevent the copper busbars from conducting electricity with the metal casing when energized and to ensure a safe distance, an insulating material is currently used between the copper busbars and the metal plate to prevent conductivity. This material can be FR4 epoxy board, ABS plastic, or bakelite board. The insulating material is processed into a suitable shape using milling and drilling techniques. The processed insulating part is then fitted onto the protruding copper busbar, and bolts are used to connect and fix the insulating part to the outer casing. This method has problems such as significant waste of raw materials, cumbersome installation, and high labor costs.

[0004] To address the aforementioned problems, this utility model proposes a copper busbar installation and protection structure. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model proposes a copper busbar installation protection structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a copper busbar installation protection structure, comprising a protective plate, an outer cabinet plate, and a copper busbar. The protective plate is fixedly attached to the outer cabinet plate, and a square hole is provided on the outer cabinet plate. Two elastic blocks are fixedly attached to both the upper and lower sides of the protective plate, and a limiting groove is provided on each elastic block near the protective plate. An inclined surface is provided on the end of each elastic block away from the protective plate, and the inclined surface of the elastic block abuts against the inner edge of the square hole. A copper busbar outlet is provided in the middle of the protective plate, and the copper busbar is inserted into the copper busbar outlet.

[0007] The present invention is further configured such that multiple sliding rods are slidably installed on both the upper and lower sides of the protective plate, one end of the sliding rod is fixedly installed with an abutment plate located inside the limiting groove, the other end of the sliding rod is fixedly connected with an end plate, and a spring is sleeved on the outside of the sliding rod, one end of the spring is fixedly connected to the end plate, and the other end of the spring is fixedly connected to the protective plate.

[0008] The present invention is further provided that an anti-slip pad is fixedly installed on the side of the abutment plate away from the slide rod.

[0009] The present invention is further provided that a weight-reducing groove is provided on one side of the protective plate corresponding to the square hole.

[0010] The present invention is further provided that rubber pads are fixedly installed on both the upper and lower sides of the inside of the copper busbar outlet, and guide slopes are provided on both rubber pads.

[0011] The present invention is further provided with limiting reinforcing ribs on the left and right sides of the protective plate, and limiting steps on the upper and lower sides of the protective plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This copper busbar installation protective structure comprises a protective plate, elastic locking blocks (with limiting grooves and bevels), a sliding rod, an abutment plate, and a spring. During installation, after the copper busbar passes through the square hole, the protective plate is pushed along the busbar. The beveled surface of the elastic locking block contacts the edge of the square hole and deforms under pressure until the limiting groove engages with the edge of the square hole to complete positioning. Simultaneously, the outer panel of the cabinet compresses the anti-slip pad, causing the sliding rod to slide and stretch the spring to generate continuous clamping force. This structure, through the mechanical interlocking of the elastic locking blocks and the adaptive adjustment of the spring, achieves quick "push-and-lock" installation, ensuring accurate positioning of the copper busbar and adapting to the installation requirements of cabinet outer panels of different thicknesses, significantly improving assembly efficiency and operational flexibility.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a copper busbar installation protection structure, including a protective plate 1, a cabinet outer plate 2, and a copper busbar 7. The protective plate 1 is snapped onto the cabinet outer plate 2. A square hole 3 is provided on the cabinet outer plate 2. Two elastic locking blocks 4 are fixed to the upper and lower sides of the protective plate 1. Each elastic locking block 4 has a limiting groove 5 near the protective plate 1. The end of each elastic locking block 4 away from the protective plate 1 is provided with an inclined surface, which abuts against the inner edge of the square hole 3. A copper busbar outlet 6 is provided in the middle of the protective plate 1, and the copper busbar 7 is inserted into the copper busbar outlet 6. The cooperation between the elastic locking blocks 4 and the square hole 3 enables quick snap-fit ​​installation, improving assembly efficiency. The copper busbar outlet 6 ensures accurate positioning of the copper busbar 7 and avoids displacement.

[0024] Furthermore, multiple sliding rods 8 are slidably installed on both the upper and lower sides of the protective plate 1. An abutment plate 9 is fixedly installed at one end of each sliding rod 8, located inside the limiting groove 5. An end plate 10 is fixedly connected to the other end of each sliding rod 8. A spring 11 is sleeved on the outer side of each sliding rod 8, with one end of the spring 11 fixedly connected to the end plate 10 and the other end fixedly connected to the protective plate 1. The cooperation between the sliding rods 8 and the springs 11 enables the abutment plate 9 to have self-adjusting capability, adapting to cabinet outer panels 2 of different thicknesses. The elastic force of the springs 11 ensures that the abutment plate 9 always presses firmly against the edge of the square hole 3, enhancing connection stability.

[0025] In this embodiment of the invention, an anti-slip pad 12 is fixedly installed on the side of the abutment plate 9 away from the slide rod 8. The anti-slip pad 12 increases the coefficient of friction, prevents relative sliding between the protective plate 1 and the outer panel 2 of the cabinet, and improves installation reliability.

[0026] In this embodiment of the invention, a weight-reducing groove 13 is provided on one side of the protective plate 1 corresponding to the square hole 3. The weight-reducing groove 13 reduces the weight of the protective plate 1 while ensuring structural strength, thereby reducing material costs and facilitating handling and installation.

[0027] In this embodiment of the invention: rubber pads 14 are fixedly installed on both the upper and lower sides of the copper busbar outlet 6, and guide slopes 15 are provided on the rubber pads 14. The rubber pads 14 provide cushioning and insulation protection to prevent wear on the copper busbar 7; the guide slopes 15 facilitate the insertion of the copper busbar 7 and improve assembly convenience.

[0028] In this embodiment of the invention: Limiting reinforcing ribs 16 are provided on the left and right sides of the protective plate 1, and limiting steps 17 are provided on the upper and lower sides of the protective plate 1. The length and width dimensions of the square hole 3 are consistent with the dimensions between the limiting reinforcing ribs 6 and the limiting steps 7. The limiting reinforcing ribs 16 enhance the structural strength of the protective plate 1 and prevent deformation; the limiting steps 17 precisely match the square hole 3 to ensure accurate installation and positioning, and avoid misalignment.

[0029] Working principle:

[0030] The copper busbar 7 extends outward from the inside of the cabinet and passes through the square hole 3 of the outer panel 2. The protective structure for the copper busbar is pre-fitted onto the copper busbar 7 through its copper busbar outlet 6, and then the protective plate 1 is brought close to the outer panel 2. During the advancement process, the elastic blocks 4 on the upper and lower sides of the protective plate 1 contact the inner edge of the square hole 3 with their inclined surfaces. Under the continuous application of external force, the elastic blocks 4 are squeezed and elastically deformed inward, allowing the protective plate 1 to move further towards the outer panel 2. When the protective plate 1 is advanced to the set position, the inner sidewall of the square hole 3 completely slides into the limiting groove 5 of the elastic block 4. At this time, the elastic block 4 returns to its original shape due to the release of pressure, and the sidewall of its limiting groove 5 forms a snap-fit ​​engagement with the edge of the square hole 3. At the same time, the inner edge of the square hole 3 of the outer panel 2 is tightly abutted against the anti-slip pad 12 on the abutment plate 9, pushing the abutment plate 9 to move axially along the slide rod 8 and stretching the spring 11, causing the spring 11 to generate elastic tension. The tension is transmitted to the abutment plate 9 through the slide bar 8, so that the anti-slip pad 12 continuously presses against the inner wall of the square hole 3. At the same time, the limiting groove 5 of the elastic block 4 forms a mechanical interlock with the edge of the square hole 3, ultimately achieving the stable assembly of the protective plate 1 on the outer panel 2 of the cabinet, ensuring the positioning of the copper busbar 7 in the copper busbar outlet 6 and the overall stability of the protective structure.

[0031] Since the slide bar 8 can slide along the protective plate 1 and the extension and retraction of the spring 11 can be adaptively adjusted, the abutment plate 9 can adapt to the outer panel 2 of the cabinet with different thicknesses, ensuring that the limiting groove 5 of the elastic block 4 is always precisely engaged with the edge of the square hole 3, thereby achieving reliable installation of the protective plate 1 under various cabinet thickness conditions.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
