Description

Technical Field

[0001] The utility model relates to the technical field of copper busbar connection of a distribution cabinet, in particular to a copper busbar connection structure of a distribution cabinet. Background Art

[0002] Copper has excellent electrical conductivity. Using copper busbars in distribution cabinets ensures low-resistance current transmission between various electrical components. This is particularly critical for high-power equipment and complex electrical systems, minimizing power loss during transmission. Distribution cabinets often need to carry high currents, and copper busbars, with their large cross-sectional area and excellent conductivity, can easily handle high current loads. A good copper busbar connection reduces contact resistance and voltage drop, ensuring more stable operation of the entire electrical system.

[0003] Existing copper busbar connections in power distribution cabinets are usually installed with bolts and gaskets. Copper is a metal material with the characteristics of thermal expansion and contraction. When the ambient temperature changes, the thickness of the copper busbar will change, and the existing gaskets are not sufficient to cope with such changes, resulting in insufficient clearance at the connection to accommodate the expansion. At this time, stress will be generated, which may cause the connecting bolts to loosen or the connecting pieces to deform, thereby increasing contact resistance, causing heat, and even electrical failures. Therefore, it is necessary to provide a copper busbar connection structure that can adapt to the influence of thermal expansion and contraction to ensure the normal use of the copper busbar. Utility Model Content

[0004] The purpose of the present utility model is to provide a copper busbar connection structure for a distribution cabinet to solve the problem raised in the above-mentioned background technology that the existing copper busbar connection of a distribution cabinet is usually installed by bolts in combination with gaskets. Copper is a metal material with the characteristics of thermal expansion and contraction. When the ambient temperature changes, the thickness of the copper busbar will change, and the existing gasket is not sufficient to cope with such changes, so that the connection part does not have enough gap to accommodate the expansion. At this time, stress will be generated, which may cause the connecting bolts to loosen or the connecting piece to deform, thereby increasing the contact resistance, causing heat, and even causing electrical failures.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a copper busbar connection structure for a power distribution cabinet, comprising:

[0007] Base and copper busbar;

[0008] An anti-displacement assembly, comprising a card slot, a first mounting slot, a spring, and a second mounting slot;

[0009] Four slots are provided on the base, and the base is movably connected to one end of the copper busbar through the slots. The four corners of one end of the copper busbar are provided with first mounting slots, and the first mounting slots are used to fix one end of the clamping spring. The four corners of the slots are provided with second mounting slots, and the second mounting slots are used to fix the other end of the clamping spring.

[0010] Furthermore, the depth of the slot is greater than the thickness of the copper busbar.

[0011] Furthermore, when the spring is not deformed, its length is greater than the depth of the slot.

[0012] Furthermore, the anti-displacement assembly further includes a first threaded hole, a second threaded hole and a fixing screw;

[0013] A first threaded hole is formed through the copper busbar, and a second threaded hole is formed on the base. A fixing screw is movably inserted between the first threaded hole and the second threaded hole.

[0014] Furthermore, it also includes a high-efficiency heat dissipation component, which includes a corrugated heat sink;

[0015] The surface of the copper busbar is fixedly mounted with wavy heat sinks, and the wavy heat sinks are arranged at equal distances.

[0016] Furthermore, the high-efficiency heat dissipation component further includes heat dissipation holes;

[0017] The copper busbar is provided with heat dissipation holes, which are arranged at equal distances.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] The utility model provides a sufficiently large reaction space for the copper busbar to expand when heated because the depth of the card slot is greater than the thickness of the copper busbar. The installed spring can always maintain sufficient clamping force when the copper busbar expands and contracts, thereby avoiding loosening. This ensures that the copper busbar functions normally, avoids electrical failures, and ensures the safety of the device.

[0020] Based on the above beneficial effects, the provision of wavy heat sinks and heat dissipation holes significantly increases the contact area between the copper busbar and the air, thereby improving the heat dissipation effect; at the same time, compared with the smooth surface of the copper busbar, the corrugated structure provides more heat dissipation channels, so that heat can be transferred to the surrounding air more quickly; and when the air flows through the corrugations, turbulence is generated, which enhances the heat exchange effect. This turbulent effect enables the air to more fully take away the heat from the surface of the copper busbar, further improving the heat dissipation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] See also Figure 1-6 As shown, this embodiment is a copper busbar connection structure for a power distribution cabinet, comprising:

[0036] Base 101 and copper busbar 102;

[0037] The anti-displacement component includes a card slot 201, a first mounting slot 202, a spring 203 and a second mounting slot 204;

[0038] Four slots 201 are formed on the base 101, and the base 101 is movably connected to one end of the copper busbar 102 through the slots 201. The four corners of one end of the copper busbar 102 have first mounting slots 202, and the first mounting slots 202 are fixed to one end of the spring 203. The four corners of the slot 201 have second mounting slots 204, and the second mounting slots 204 are fixed to the other end of the spring 203.

[0039] The base 101 is used to connect the power distribution cabinet and the copper busbar 102. The setting of the card slot 201 provides a guarantee for the initial connection of the base 101 to the copper busbar 102. The setting of the first mounting slot 202 and the second mounting slot 204 provides a guarantee for the stable connection of the spring 203. The setting of the spring 203 provides a guarantee for fully clamping the copper busbar 102.

[0040] The depth of the slot 201 is greater than the thickness of the copper busbar 102;

[0041] The size of the slot 201 and the copper busbar 102 can ensure that there is sufficient space for the copper busbar 102 to expand when it is heated.

[0042] When the spring 203 is not deformed, its length is greater than the depth of the slot 201;

[0043] The dimensions of the spring 203 and the slot 201 are configured to ensure that the spring 203 always has a clamping force.

[0044] The anti-displacement assembly further includes a first threaded hole 205, a second threaded hole 206 and a fixing screw 207;

[0045] A first threaded hole 205 is formed through the copper busbar 102, and a second threaded hole 206 is formed on the base 101. A fixing screw 207 is movably inserted between the first threaded hole 205 and the second threaded hole 206.

[0046] The above components are used in conjunction with each other to realize the installation and removal of the copper busbar 102;

[0047] It also includes a high-efficiency heat dissipation component, which includes a wave-shaped heat sink 301;

[0048] The surface of the copper busbar 102 is fixedly mounted with wavy heat sinks 301, and the wavy heat sinks 301 are arranged at equal distances;

[0049] The arrangement of the wavy heat sink 301 ensures efficient heat dissipation in the copper bus 102.

[0050] The high-efficiency heat dissipation component also includes heat dissipation holes 302;

[0051] The copper busbar 102 is provided with heat dissipation holes 302 , which are arranged at equal distances.

[0052] The provision of the heat dissipation holes 302 can increase the heat dissipation area between the copper busbar 102 and the air;

[0053] Working principle: First, the base 101 is fixedly installed inside the power distribution cabinet, and then one end of the spring 203 is fixedly clamped into the second mounting slot 204, and the other end of the spring 203 is fixedly clamped into the first mounting slot 202. At this time, one end of the copper busbar 102 is movably clamped in the clamping slot 201, and then the fixing screw 207 is screwed into the first threaded hole 205 and the second threaded hole 206 in sequence to complete the installation of the copper busbar 102 and the base 101;

[0054] This step can provide a sufficiently large reaction space for the copper busbar to expand when heated. At the same time, the installed spring can always maintain sufficient clamping force when the copper busbar expands and contracts, thereby preventing loosening. This ensures that the copper busbar functions normally, avoids causing electrical failures, and ensures the safety of the device. In addition, the provision of the wavy heat sink and the heat dissipation holes effectively improves the heat dissipation effect.
