Description

Technical Field

[0001] This utility model relates to the field of alloy busbar technology, specifically a high-current sealing structure for alloy busbars. Background Technology

[0002] In the complex working conditions of industrial plants, high-current busbar trunking plays a critical role in the distribution of high-power electricity. Its sealing failure may cause equipment failure and affect the continuous operation of the production line. As a high-precision power environment, data centers have even more stringent requirements for the sealing of busbar trunking.

[0003] According to announcement number CN214069492U, a busbar trunking with good sealing effect includes a busbar trunking body, a connector is provided on the left side of the busbar trunking body, a limiting plate is fixedly connected to the inner wall of the busbar trunking body, a sealing gasket is fixedly connected to the left side of the limiting plate, and the right side of the connector extends into the inner cavity of the busbar trunking body and contacts the sealing gasket.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, the magnetic field generated by the alternating current in the device induces eddy currents in the metal shell. Eddy current losses cause local temperature rise in the metal parts of the sealing structure, accelerating the thermal and oxidative aging of the rubber seals. This necessitates periodic replacement of the shell. The connection between the shells is simply fixed with bolts, and the uniformity of the preload of the bolt connection is difficult to guarantee. During thermal expansion and contraction cycles, local loosening is likely to occur, leading to pressure attenuation at the sealing interface. Utility Model Content

[0006] The purpose of this invention is to provide a high-current sealing structure for alloy busbar trunking to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-current sealing structure for alloy busbar trunking, comprising a U-shaped lower shell and a U-shaped upper shell, wherein a connecting mechanism is provided on the U-shaped lower shell and the U-shaped upper shell, and a fixing mechanism is provided on the connecting mechanism;

[0008] The connecting mechanism includes a long groove, which is formed on the left and right sides of the inner wall of the U-shaped upper shell. Long plates are fixedly connected to the left and right sides of the U-shaped lower shell. Slots are formed on the outer sides of the two long plates. Inserts are inserted into the slots. Connecting seats are fixedly connected to the outer sides of the inserts on the left and right sides. Connecting plates are fixedly connected to the top of the connecting seats. Slide plates are fixedly connected to the two connecting plates away from the connecting seats. Limiting seats are fixedly connected to both ends of the top of the U-shaped upper shell. There are four limiting seats, which are arranged in pairs. A long rod is fixedly connected between two limiting seats.

[0009] Preferably, the number of slots is four, and they are arranged in pairs. The slot openings on the left and right sides are correspondingly opened. When the plug is inserted into the slot, the U-shaped upper shell can be fixedly set on the top of the U-shaped lower shell to achieve high current sealing. Conversely, it is also convenient to replace the U-shaped upper shell and the U-shaped lower shell if they are damaged.

[0010] Preferably, there are two skateboards and two long poles, and the inside of the skateboard and the surface of the long pole are slidably connected.

[0011] Preferably, the U-shaped upper shell has through slots on the left and right sides, and the surface of the insert block is inserted through the through slots on the left and right sides of the U-shaped upper shell.

[0012] Preferably, the fixing mechanism includes T-slots, which are densely arranged on the top of the slide plate. The long rod has densely arranged insertion slots inside. A T-block is slidably connected inside the T-slots. A fixing seat is fixedly connected to the top of the T-block. A fixing plate is fixedly connected to the bottom of the fixing seat. An insertion rod is fixedly connected to the side of the fixing plate near the long rod. Screws are threadedly connected to the fixing plate and the slide plate.

[0013] Preferably, the front and rear sides of the insertion slot are set as openings, and the surface of the insertion rod is inserted into the inside of the insertion slot. The insertion rod is inserted into the insertion slot, which can limit and fix the position of the insertion block, making it easier to install the U-shaped upper shell on the top of the U-shaped lower shell more firmly.

[0014] Preferably, the insert rods are arranged in pairs, with each pair of insert rods positioned on the outside of two slide plates.

[0015] Compared with the prior art, this utility model provides a high-current sealing structure for alloy busbar trunking, which has the following advantages:

[0016] 1. The high-current sealing structure used in this alloy busbar trunking uses a connecting mechanism. The long plate is inserted into the long groove, and the sliding plate is pushed to slide on the surface of the long rod until the sliding plate drives the connecting plate. The connecting plate drives the connecting seat, and the connecting seat drives the plug to be inserted into the slot. The U-shaped upper shell can be fixed on the top of the U-shaped lower shell to achieve high-current sealing. Conversely, if the U-shaped upper shell and U-shaped lower shell are damaged, they can be easily replaced.

[0017] 2. The high-current sealing structure used in this alloy busbar trunking uses a fixing mechanism. The fixing seat drives the T-shaped block to slide in the T-shaped groove until the fixing seat drives the fixing plate. The fixing plate drives the plug rod to be inserted into the plug slot.

A connecting mechanism 3 is provided on the U-shaped lower housing 1 and the U-shaped upper housing 2, and a fixing mechanism 4 is provided on the connecting mechanism 3.

[0031] The connecting mechanism 3 includes a long groove 33, which is opened on the left and right sides of the inner wall of the U-shaped upper shell 2. Long plates 31 are fixedly connected to the left and right sides of the U-shaped lower shell 1 respectively. Slots 32 are opened on the outer side of the two long plates 31. Inserts 34 are inserted into the slots 32. Connecting seats 35 are fixedly connected to the outer side of the inserts 34 on the left and right sides. Connecting plates 36 are fixedly connected to the top of the connecting seats 35. Slide plates 38 are fixedly connected to the side of the front and rear connecting plates 36 away from the connecting seats 35. Limiting seats 39 are fixedly connected to the top two ends of the U-shaped upper shell 2 respectively. There are four limiting seats 39, which are in pairs. A long rod 37 is fixedly connected between two limiting seats 39.

[0032] There are four slots 32, which are in pairs. The openings of the slots 32 on the left and right sides correspond to each other. There are two slide plates 38 and two long rods 37. The inside of the slide plate 38 and the surface of the long rod 37 are slidably connected. The inside of the left and right sides of the U-shaped upper housing 2 is provided with through slots. The surface of the insert block 34 is inserted through the through slots provided on the left and right sides of the U-shaped upper housing 2.

[0033] Furthermore, the long plate 31 is inserted into the long slot 33, pushing the slide plate 38 to slide on the surface of the long rod 37 until the slide plate 38 drives the connecting plate 36, the connecting plate 36 drives the connecting seat 35, and the connecting seat 35 drives the insert block 34 to be inserted into the slot 32. This can fix the U-shaped upper housing 2 on the top of the U-shaped lower housing 1 to achieve high current sealing. Conversely, it is also convenient to replace the U-shaped upper housing 2 and the U-shaped lower housing 1 when they are damaged.

[0034] Example 2

[0035] See Figure 1-6Furthermore, based on Embodiment 1, the fixing mechanism 4 includes T-slots 44, which are densely arranged on the top of the slide plate 38. Insertion slots 41 are densely arranged inside the long rod 37. T-blocks 43 are slidably connected inside the T-slots 44. A fixing seat 45 is fixedly connected to the top of the T-blocks 43. A fixing plate 46 is fixedly connected to the bottom of the fixing seat 45. An insertion rod 47 is fixedly connected to the side of the fixing plate 46 near the long rod 37. Screws 42 are threadedly connected to the fixing plate 46 and the slide plate 38.

[0036] The front and rear sides of the insertion slot 41 are set as openings, and the surface of the insertion rod 47 is inserted into the inside of the insertion slot 41. The insertion rods 47 are in pairs, and each pair of insertion rods 47 is set on the outside of the two slide plates 38.

[0037] Furthermore, the fixing seat 45 drives the T-block 43 to slide in the T-slot 44 until the fixing seat 45 drives the fixing plate 46, and the fixing plate 46 drives the insertion rod 47 to be inserted into the insertion slot 41. The fixing plate 46 and the sliding plate 38 are threadedly fixed by the screw 42, which can limit and fix the position of the insertion block 34, making it easier to install the U-shaped upper housing 2 on the top of the U-shaped lower housing 1 more firmly.

[0038] In actual operation, when this device is used and sealing of high current is required, a U-shaped groove (12mm deep, 10mm wide) is designed at the joint of the U-shaped lower housing 1 and the U-shaped upper housing 2. A conductive sealing strip (silver-filled silicone rubber, 6×6mm cross-section) is embedded in the groove, and a 15° beveled guide surface (10mm long) is machined at the interface edge. Simultaneously, the U-shaped structure avoids the formation of closed eddy current loops, reducing eddy current loss by 35% compared to traditional closed interfaces. The beveled guide surface reduces magnetic field concentration, and combined with the low resistance characteristics of the conductive rubber (conductivity 2×10⁻⁶), it effectively mitigates the problem. 4 S / m), which can make the grounding impedance at the interface ≤15mΩ;

[0039] Insert the long plate 31 into the long slot 33, push the slide plate 38 to slide on the surface of the long rod 37 until the slide plate 38 drives the connecting plate 36, the connecting plate 36 drives the connecting seat 35, and the connecting seat 35 drives the insert block 34 to be inserted into the slot 32. The U-shaped upper housing 2 can be fixedly set on the top of the U-shaped lower housing 1 to achieve high current sealing. Conversely, if the U-shaped upper housing 2 and the U-shaped lower housing 1 are damaged, it is also convenient to replace them.

[0040] Push the fixing seat 45 again to make the T-block 43 slide in the T-slot 44 until the fixing seat 45 drives the fixing plate 46, and the fixing plate 46 drives the insertion rod 47 to be inserted into the insertion slot 41. Use the screw 42 to fix the fixing plate 46 and the sliding plate 38 with threads, so that the position of the insertion block 34 can be limited and fixed, making it easier to install the U-shaped upper housing 2 on the top of the U-shaped lower housing 1 more firmly.
