Description

Technical Field

[0001] This utility model relates to the field of flexible copper busbar technology, specifically a flexible copper busbar with rapid heat dissipation function. Background Technology

[0002] Flexible copper busbars are widely used in power equipment, new energy batteries, and rail transportation to achieve flexible connections between electrical equipment. Under high current loads, flexible copper busbars are prone to generating a lot of heat. If heat dissipation is not timely, the temperature of the copper busbar will rise, which will affect its conductivity and service life.

[0003] In the existing technology, although some copper busbars have added heat dissipation structures, the position of the heat sink is fixed and cannot be adjusted. When installing flexible copper busbars, it is often necessary to bend them. However, the heat sinks fixedly installed on the part to be bent will hinder the bending, causing inconvenience in installation. Moreover, in complex working conditions with high current load or limited space, it is impossible to specifically dissipate heat in areas with high heat generation. Utility Model Content

[0010] Preferably, several of the sliders are slidably connected inside the long groove, and the upper end of the slider is fixedly connected to the heat sink. L-shaped inserts are sleeved on the outside of the slider near both ends.

Detailed Implementation

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] A flexible copper busbar with rapid heat dissipation function, as described in the reference. Figures 1-7 The device includes a soft copper core 2, which is covered with an insulating protective sleeve 1. The insulating protective sleeve 1 is made of rubber and is used to protect and insulate the soft copper core 2. The outer wall of the insulating protective sleeve 1 has a long groove 4. A support bar 1 5 is fixedly connected to the inner wall of one side of the long groove 4, and a support bar 2 13 is fixedly connected to the inner wall of the other side of the long groove 4 to support the heat sink 6 and provide a track for its sliding. Several heat sinks 6 are covered with the outer wall of the insulating protective sleeve 1. Several slots 18 are opened through the outer wall of the heat sink 6. The heat sink 6 is embedded in the long groove 4 by a slider 9 at the bottom and can slide along the long groove 4. The slots 18 are opened on the outer wall of the heat sink to increase the heat dissipation area. Each of the heat sinks 6 has an adjustment mechanism. Both ends of the soft copper core 2 are fixedly connected to a connector 3. The adjustment mechanism includes a slide groove 14, which is opened through the outer wall of the heat sink 6. A slide rod 10 is fixedly installed inside the slide groove 14.

[0030] Both connectors 3 have mounting holes 16 through their outer walls. Support bars 17 are fixedly connected to the outer walls of support bars 11 and 2 near both ends. The support bars 17 prevent the heat sink 6 from sliding out of the long slot 4. Support bars 11 and 2 are made of titanium alloy, which is non-conductive and has deformation capability, thus providing a certain degree of reinforcement to the copper busbar.

[0031] The adjustment mechanism also includes several sliders 9 and several slots 12. The slots 12 are respectively opened on the outer wall of support bar 1 5 and support bar 2 13. The sliders 9 are all slidably connected inside the long slot 4, and the upper end of the slider 9 is fixedly connected to the heat sink 6. L-shaped inserts 19 are sleeved on the outside of the slide bar 10 near both ends. By using the sliders 8 in conjunction with the long slot 4, each heat sink 6 can be moved conveniently along the outside of the insulating protective sleeve 1.

[0032] One end of the L-shaped insert plate 19 fits into the slot 12. A tension spring 15 is sleeved on the outside of the slide rod 10 and located between the two L-shaped insert plates 19. The two tension springs 15 are fixedly connected to the two L-shaped insert plates 19 respectively. A toggle plate 11 is fixedly connected to the upper end of each L-shaped insert plate 19. By bringing the toggle plates 11 closer together, the two L-shaped insert plates 19 are moved along the slide rod 10, which can move one end of the two L-shaped insert plates 19 out of the two slots 12 respectively, releasing the connection between the heat sink 6, the support bar 2 13 and the support bar 1. With the fins fixed between 5, the tension spring 15 is compressed and contracted. At this time, the heat sink 6 can be moved along the outside of the insulating protective sleeve 1. Adjust the position of each heat sink 6 outside the insulating protective sleeve 1 as needed. After adjustment, release the two toggle plates 11. Under the action of the rebound force of the tension spring 15, the two L-shaped insert plates 19 can be moved to the initial position, and one end of the two L-shaped insert plates 19 can be inserted into the corresponding slots 12 respectively, thus completing the fixation of the position between the heat sink 6 and the second support bar 13 and the first support bar 5 after adjustment.

[0033] In use, fix the connectors 3 at both ends of the flexible copper busbar to the designated position on the equipment through the mounting holes 16 to ensure reliable electrical connection. Then move the two toggle plates 11 on the heat sink 6 that needs to be adjusted so that the L-shaped insert 19 can be dislodged from the slot 12. Slide the heat sink along the long groove 4 to the heat concentration area, while avoiding the bending part of the flexible copper busbar to avoid hindering the bending of the flexible copper busbar and obstructing installation. Then release the toggle plates, and under the action of the spring 15, drive the L-shaped insert 19 to reset and re-insert it into the corresponding slot 12 to complete the fixation of the heat sink 6. When powered on, the heat generated by the flexible copper core 2 is conducted to each heat sink 6, and the heat sink 6 increases the heat dissipation area through the slot 18 to achieve rapid heat dissipation.

[0034] The outer wall of the insulating protective sleeve 1 has several grooves 7, and a hexagonal heat dissipation frame 8 is fixedly connected inside each groove 7. The grooves 7 are evenly distributed, and the hexagonal heat dissipation frame 8 is filled with a heat conductor 20. The grooves 7 on the outer wall of the insulating protective sleeve 1 and the hexagonal heat dissipation frame 8 inside can increase the contact area with the external space through the hexagonal structure, thereby improving the heat conduction efficiency. The heat conductor 20, such as thermal grease, is filled inside to accelerate the heat conduction from the soft copper core 2 to the heat sink 6, thereby improving the heat dissipation effect.

[0035] Specifically, when powered on, the heat generated by the soft copper core 2 is simultaneously conducted to the hexagonal heat sink 8 through the insulating protective sleeve 1. The heat conductor 20 accelerates the heat transfer and further improves the heat dissipation effect. The hexagonal heat sink 8 is made of silicone rubber, which has excellent thermal conductivity.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
