Description

Technical Field

[0001] This utility model relates to the field of laminated busbar technology, and in particular to a riveting gasket structure for laminated busbars. Background Technology

[0002] As an important electrical connection element, the multilayer busbar is composed of multiple layers of conductive materials. Insulation layers are usually set between the layers to ensure electrical isolation and reduce inductance. In this structure, the use of rivet shims has become one of the key technologies to improve the interlayer connection performance. Rivet shims are mainly used to fix the conductive layers and ensure their stability under mechanical stress.

[0003] The existing riveting gasket structure for laminated busbars (publication number: CN211455966U) has at least the following drawbacks: Although the above-mentioned device presses the anti-slip teeth of the positioning end of the riveting gasket into the riveting hole of the busbar copper plate through the riveting equipment to fix the position of the gasket, the anti-slip teeth of the riveting gasket need to be pressed into the riveting hole with the aid of the riveting device before the position of the riveting gasket is fixed. Before riveting, the riveting gasket that is not fixed in position is easy to fall off from the riveting hole, resulting in poor riveting effect of laminated busbars. Therefore, we propose this utility model. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a riveting gasket structure for laminated busbars.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A riveting pad structure for a laminated busbar includes two conductive layers stacked vertically, with a first insulating layer between the two conductive layers. A second insulating layer is attached to the top and bottom surfaces of both conductive layers. A plurality of upper pads are disposed on the top surface of the upper conductive layer, and a plurality of lower pads are disposed below the lower conductive layer. A fixing structure is provided between the upper and lower pads. The fixing structure includes a plurality of riveting holes formed on the top surface of the conductive layers. A plurality of connecting holes are formed on the top surfaces of both the first and second insulating layers, with each connecting hole corresponding to one of the riveting holes. The plurality of upper and lower pads also correspond to the respective riveting holes.

[0007] As a further embodiment of this utility model, the positioning end of the upper gasket passes through the riveting hole and the connecting hole and is slidably inserted into the interior of the lower gasket. The inner wall surface of the lower gasket is provided with a plurality of positioning grooves, and each of the plurality of positioning grooves is provided with an installation groove. A fixing ring is fixed to the outer circular wall surface of the upper gasket, and the fixing ring is slidably inserted into the interior of the lower gasket. A plurality of fixing blocks are fixed to the outer circular wall surface of the fixing ring, and the plurality of fixing blocks are slidably disposed within the interior of the plurality of positioning grooves.

[0008] As a further embodiment of this utility model, a locking block is slidably inserted inside the mounting groove, and a first spring is fixed inside the mounting groove, with one end of the first spring fixed to one side of the locking block.

[0009] As a further embodiment of this utility model, the ends of the locking block and the fixing block that are close to each other are both inclined surfaces, and the two inclined surfaces are inclined in the same direction.

[0010] As a further embodiment of this utility model, the width of the positioning groove is greater than the width of the fixing block, an arc rod is slidably inserted into one side of the fixing block, one end of the arc rod is fixed with an abutment plate, the abutment plate abuts against one side of the inner wall of the positioning groove, and a second spring is wound around the outer circular wall of the arc rod, with the two ends of the second spring abutting against one side of the fixing block and one side of the abutment plate, respectively.

[0011] As a further embodiment of this utility model, limit strips are fixed on both sides of the locking block, and limit grooves are opened on both sides of the inner wall of the mounting groove, with the limit strips slidingly disposed within the limit grooves.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This riveting gasket structure, through a fixed structure setting, has the positioning end of the upper gasket inserted into the interior of the lower gasket. The fixing block on the outer circular wall of the fixing ring is inserted into the positioning groove. The locking block is squeezed into the mounting groove by the fixing block. The first spring is compressed, and the locking block pops out under the action of the first spring to lock the fixing block, thereby preventing the positioning end of the upper gasket from detaching from the lower gasket. This achieves the fixation between the upper and lower gaskets, preventing them from detaching from the riveting hole, thus facilitating the riveting of single or multiple busbars and improving the riveting effect of the busbars.

[0023] like Figures 1-5As shown, a riveting pad structure for a laminated busbar includes two conductive layers 1 stacked vertically, with a first insulating layer 2 between the two conductive layers 1. A second insulating layer 3 is attached to the top and bottom surfaces of both conductive layers 1. Several upper pads 4 are provided on the top surface of the upper conductive layer 1, and several lower pads 5 are provided below the lower conductive layer 1. A fixing structure is provided between the upper pads 4 and the lower pads 5. The fixing structure includes several riveting holes 201 on the top surface of the conductive layer 1. Several connecting holes 202 are provided on the top surfaces of both the first insulating layer 2 and the second insulating layer 3. The connecting holes 202 correspond to the positions of the riveting holes 201, and the upper pads 4 and lower pads 5 correspond to the positions of the riveting holes 201. The upper pads 4 and their positioning ends are a combination of annular and cylindrical structures, and the lower pads 5 are annular structures.

[0024] In this embodiment, the positioning end of the upper gasket 4 passes through the riveting hole 201 and the connecting hole 202 and is slidably inserted into the interior of the lower gasket 5. The inner wall surface of the lower gasket 5 is provided with a plurality of positioning grooves 203, and each of the plurality of positioning grooves 203 is provided with an installation groove 204. A fixing ring 208 is fixed on the outer circular wall surface of the upper gasket 4. The fixing ring 208 is slidably inserted into the interior of the lower gasket 5. A plurality of fixing blocks 207 are fixed on the outer circular wall surface of the fixing ring 208. The plurality of fixing blocks 207 are slidably disposed in the interior of the plurality of positioning grooves 203. Through the positioning grooves 203 and the fixing blocks 207, the positioning end of the upper gasket 4 and the fixing ring 208 can be accurately inserted into the lower gasket 5.

[0025] In this embodiment, a locking block 205 is slidably inserted into the mounting groove 204, and a first spring 206 is fixed inside the mounting groove 204. One end of the first spring 206 is fixed to one side of the locking block 205. Through this fixing structure, the operator inserts the positioning end of the upper gasket 4 through the riveting hole 201 of the upper conductive layer 1, so that the positioning end of the upper gasket 4 passes through the riveting holes 201 and the connecting hole 202 of the two conductive layers 1 and reaches the bottom of the second insulating layer 3. Then, the lower gasket 5 is placed at the connecting hole 202 on the bottom surface of the second insulating layer 3, so that the positioning end of the upper gasket 4 is inserted into the interior of the lower gasket 5. When the positioning end of the upper gasket 4 is inserted, the fixing block 207 on the outer circular wall of the fixing ring 208... Insert the fixing block 207 into the positioning groove 203 to position the positioning end within the lower pad 5. When the fixing block 207 is inserted into the positioning groove 203, the locking block 205 is squeezed into the mounting groove 204 by the fixing block 207 and compressed by the first spring 206. When the fixing block 207 moves below the locking block 205, the locking block 205 pops out under the action of the first spring 206 to lock the fixing block 207, thereby preventing the positioning end of the upper pad 4 from detaching from the lower pad 5. This achieves the fixation between the upper pad 4 and the lower pad 5, preventing the upper pad 4 and the lower pad 5 from detaching from the riveting hole 201, thus facilitating the riveting of single or multiple busbars by the workers and improving the riveting effect of the busbars.

[0026] In this embodiment, the ends of the locking block 205 and the fixing block 207 that are close to each other are both inclined surfaces, and the two inclined surfaces are inclined in the same direction. When the fixing block 207 is inserted into the positioning groove 203 and contacts the locking block 205, the design of the inclined surfaces makes it easier for the fixing block 207 to squeeze the locking block 205 into the mounting groove 204.

[0027] In this embodiment, the width of the positioning groove 203 is greater than the width of the fixing block 207. An arc rod 301 is slidably inserted into one side of the fixing block 207. One end of the arc rod 301 is fixed with an abutment plate 302. The abutment plate 302 abuts against one side of the inner wall of the positioning groove 203. A second spring 303 is wound around the outer circular wall of the arc rod 301. The two ends of the second spring 303 abut against one side of the fixing block 207 and one side of the abutment plate 302, respectively. When the worker needs to detach the unriveted upper gasket 4 and lower gasket 5, the worker can rotate the upper gasket 4 to move the fixing block 207 closer to the abutment plate 302. The second spring 303 is compressed, the arc rod 301 retracts into the fixing block 207, and the fixing block 207 is released from the limit of the locking block 205, thereby facilitating the worker to detach the upper gasket 4 and lower gasket 5.

[0028] In this embodiment, limit strips 401 are fixed on both sides of the locking block 205, and limit grooves 402 are opened on both sides of the inner wall of the mounting groove 204. The limit strips 401 and the limit grooves 402 are slidably arranged inside each other. The movement of the locking block 205 can be limited and guided by the cooperation of the limit strips 401 and the limit grooves 402.

[0029] Working principle: In use, the operator inserts the positioning end of the upper gasket 4 through the riveting hole 201 of the upper conductive layer 1, so that the positioning end of the upper gasket 4 passes through the riveting holes 201 and the connecting hole 202 of the two conductive layers 1, reaching the bottom of the second insulating layer 3. Then, the lower gasket 5 is placed at the connecting hole 202 on the bottom surface of the second insulating layer 3, so that the positioning end of the upper gasket 4 is inserted into the interior of the lower gasket 5. When the positioning end of the upper gasket 4 is inserted, the fixing block 207 on the outer circular wall of the fixing ring 208 is inserted into the positioning groove 203 to position the positioning end in the lower gasket 5. When the fixing block 207 is inserted into the positioning groove 203, the locking block 205 is squeezed into the mounting groove 204 by the fixing block 207, and the first spring 206 is compressed. When the fixing block 207 moves to the bottom of the locking block 205, the locking block 205 pops out under the action of the first spring 206 and locks the fixing block 207. The upper gasket 4 is fixed in place, preventing the positioning end of the upper gasket 4 from detaching from the lower gasket 5, thus fixing the upper gasket 4 and the lower gasket 5 and preventing them from detaching from the riveting hole 201. When the fixing block 207 is inserted into the positioning groove 203 and contacts the locking block 205, the inclined surface design facilitates the fixing block 207 to squeeze the locking block 205 into the mounting groove 204. When the worker needs to detach the unriveted upper gasket 4 and lower gasket 5, the worker can rotate the upper gasket 4, causing the fixing block 207 to move closer to the abutment plate 302. The second spring 303 is compressed, the arc rod 301 retracts into the fixing block 207, and the fixing block 207 is released from the limit of the locking block 205, thus facilitating the worker to detach the upper gasket 4 and the lower gasket 5. The movement of the locking block 205 can be limited and guided by the cooperation of the limiting strip 401 and the limiting groove 402.

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.
