Description

Technical Field

[0001] This utility model relates to the field of copper busbars, specifically a high-power copper busbar. Background Technology

[0002] Copper busbars are conductive busbars made primarily of copper. They are widely used in power equipment, power distribution systems, switch cabinets, transformers, UPS, charging piles, and new energy equipment. Their main function is to conduct electricity and shunt current, and they are a basic component of electrical equipment.

[0003] Publication number CN209592905U discloses a high-power medium- and high-frequency power supply busbar, the structure of which includes an electroplated copper busbar, brass bolts, a first fixing bolt, a second fixing bolt, a first insulator, a second insulator, a hub device, and a displacement device. By setting the displacement device at the bottom of the first insulator, the problem of inconvenience in small-distance position adjustment and its disadvantage in subsequent use is solved. Turning the knob counterclockwise causes the slider to loosen in the slide groove, and then pushing the sliding plate causes the slider to slide in the slide groove, thereby adjusting the position of the electroplated copper busbar. After determining the position, turning the knob clockwise fixes it, so that the sliding plate no longer moves, which is beneficial to facilitate the lateral position adjustment after installation.

[0004] In the aforementioned prior art, a sliding plate is installed on the base, and a copper busbar and a knob are mounted on the sliding plate. The sliding plate moves the copper busbar, and the knob can be rotated to control whether the sliding plate can move, thus solving the problem of inconvenient small-distance position adjustment of the copper busbar. However, in actual use, since the copper busbar is a high-current conductor, it may generate corona discharge at its edges or sharp corners. Under certain conditions, air breakdown may also occur, resulting in an electric arc. In this case, even if there is no direct contact with the copper busbar, there is a safety risk just by being near it. Even in a low-voltage environment, although air discharge generally does not occur, if the copper busbar is accidentally touched during adjustment or if a metal tool accidentally comes into contact with the copper busbar, it may still cause electric shock or short circuit accidents. The existing technology of directly adjusting the position of the copper busbar by using a knob requires the operator to be close to the copper busbar, which poses certain safety hazards and is not conducive to ensuring safe use. Therefore, we propose a high-power copper busbar. Utility Model Content

[0005] The purpose of this invention is to provide a high-power copper busbar to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, a high-power copper busbar includes an electroplated copper busbar, which is mounted on the upper side of a sliding plate via an insulator. The sliding plate is slidably connected to the upper side of a base. A knob is provided between the sliding plate and the base. A fan plate is rotatably connected to the corner of the upper surface of the sliding plate near the knob. One end of the fan plate engages with the outer wall of the knob. A telescopic cylinder is fixedly connected to the top of the fan plate near the corner of the sliding plate. One end of the telescopic cylinder extends away from the sliding plate, and a pull rope is fixedly connected to the end of the telescopic cylinder.

[0007] Furthermore, a connecting seat is fixedly connected to the bottom of the fan plate, and the fan plate is also vertically movably connected to the upper surface of the slide plate through the connecting seat.

[0008] Furthermore, a positioning block is fixedly connected to the upper surface of the slide plate on the inner side of the fan plate, and the top of the positioning block is a smooth hemispherical shape.

[0009] Furthermore: a groove is provided on the inner side of the base, the outer wall of the knob is threaded to one end of the slide plate, and the lower end of the knob extends to the groove and is fixedly connected with a convex ring.

[0010] Furthermore, a stop block is fixedly connected to the lower surface of the skateboard.

[0011] Furthermore: the maximum vertical movement height of the fan plate does not exceed the lowest top height of the knob, and the lowest top height of the knob exceeds the sum of the heights of the fan plate and the positioning block.

[0012] Furthermore, the upper surface of the electroplated copper busbar is threaded with brass screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the adjustment of the copper busbar position does not require direct contact or proximity to the exposed copper busbar during the rotation of the control knob via the fan plate and telescopic cylinder. This avoids the risk of electric shock and short circuit caused by high voltage corona discharge, arc discharge, low voltage accidental contact, or tool contact. The improved design allows for quick and precise small-distance, fine-tuning displacement control of the copper busbar, avoiding the inconvenience of manual, rough adjustments.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 The figure shows a preferred embodiment of the present invention. A high-power copper busbar includes an electroplated copper busbar 1, which is mounted on the upper side of a slide plate 3 via an insulator 2. The slide plate 3 is slidably connected to the upper side of a base 4. A knob 5 is provided between the slide plate 3 and the base 4. A fan plate 6 is rotatably connected to the corner of the upper surface of the slide plate 3 near the knob 5. One end of the fan plate 6 engages with the outer wall of the knob 5. A telescopic cylinder 7 is fixedly connected to the top of the fan plate 6 near the corner of the slide plate 3. One end of the telescopic cylinder 7 extends away from the slide plate 3, and a pull rope 8 is fixedly connected to the end of the telescopic cylinder 7.

[0022] Specifically, the bottom of the fan plate 6 is fixedly connected to the connecting seat 9. The fan plate 6 is also vertically movably connected to the upper surface of the slide plate 3 through the connecting seat 9. The connecting seat 9 is located inside the slide plate 3, and its top passes through the slide plate 3 and is connected to the bottom of the fan plate 6. The fan plate 6 can be raised to a limited length on the upper side of the slide plate 3 through the connecting seat 9, and will not detach from the slide plate 3.

[0023] Understandably, in order to easily determine whether the knob 5 is tightened or loosened, a positioning block 10 is fixedly connected to the upper surface of the slide plate 3 on the inner side of the fan plate 6. Normally, when one end of the fan plate 6 moves to contact the positioning block 10, it will tighten or loosen the knob 5. The top of the positioning block 10 is a smooth hemispherical shape. It should also be noted that the height of the positioning block 10 does not exceed half the height of the fan plate 6, so that the fan plate 6 is not easily blocked by the positioning block 10 after it is raised.

[0024] like Figure 2As shown, a groove 11 is provided on the inner side of the base 4. The outer wall of the knob 5 is threaded to one end of the slide plate 3. The lower end of the knob 5 extends to the groove 11 and is fixedly connected to a convex ring 12. After rotating the knob 5 clockwise, the knob 5 is raised vertically on the slide plate 3. The convex ring 12 moves with the knob 5, so that its top abuts against the upper end of the inner wall of the groove 11, clamping the slide plate 3 and the base 4, thereby restricting the movement of the slide plate 3.

[0025] Among them, a stop block 13 is fixedly connected to the lower surface of the slide plate 3. The stop block 13 and the knob 5 are partially inserted into the groove 11, so that the slide plate 3 can only move along the base 4 on the base 4 and will not rotate.

[0026] The maximum vertical movement height of the fan plate 6 does not exceed the lowest top height of the knob 5, and the lowest top height of the knob 5 exceeds the sum of the heights of the fan plate 6 and the positioning block 10, so that the movement of the fan plate 6 will not disengage from the knob 5. It should be added that the surfaces of the knob 5 and the fan plate 6 are provided with matching tooth-like patterns or gear teeth for meshing, which are not shown in the figure.

[0027] Specifically, the upper surface of the electroplated copper busbar 1 is threaded with brass screws 14 so as to fix the wires.

[0028] In this embodiment, the surface of the telescopic cylinder 7 is provided with an insulating protective layer. Before using the copper busbar, the base 4 is first fixed in the appropriate position with bolts. In the case of power failure, the electroplated copper busbar 1 is installed on the slide plate 3 through the insulator 2. The copper wire inside the wire can be wound around the brass screw 14 and fixed to the electroplated copper busbar 1 by the brass screw 14. When it is necessary to adjust the position of the electroplated copper busbar 1 laterally, the inner section of the telescopic cylinder 7 can be pulled out from the inside by pulling the rope 8. After holding the telescopic cylinder 7, the fan plate 6 can be rotated on the top of the slide plate 3 by pushing the telescopic cylinder 7. One end of the fan plate 6 engages with the surface of the knob 5, pushing the knob 5 to rotate. Taking clockwise rotation of the knob 5 as an example, after clockwise rotation of the knob 5, the knob 5 is raised vertically on the slide plate 3, and the convex ring 12 moves with the knob 5, so that the top abuts against the upper end of the inner wall of the groove 11, clamping the slide plate 3 and the base 4, thereby restricting the movement of the slide plate 3. Conversely, the same applies. After the knob 5 is rotated counterclockwise, the slide plate 3 and the base 4 are not constrained. At this time, the slide plate 3 can be remotely pushed on the base 4 by the telescopic cylinder 7. After moving to the designated position, the knob 5 is pushed to rotate back and fix it.

[0029] It should also be added that the fan plate 6 can be lifted off the slide plate 3 via the connecting seat 9, and its stroke is not restricted by the positioning block 10. If necessary, the range of motion of the fan plate 6 and the telescopic cylinder 7 can be extended.

[0030] Finally, it should be noted that, in order to facilitate a clear demonstration and understanding of the structure of this invention, the accompanying drawings are not drawn strictly according to the actual scale. The drawings may contain enlarged, reduced, or distorted representations of specific components, spacing, or angles.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
