Abstract
Description
Technical Field
[0001] This utility model belongs to the field of conductive busbar connection technology, and in particular relates to a conductive busbar connection component and connection structure. Background Technology
[0002] In existing technologies, conductive busbars are increasingly used. There are generally two ways to connect two conductive busbars. One is welding, but this method has the problems of high cost and long time consumption. At the same time, it is necessary to control the welding heat and the problem of poor welding. The other is to use connectors to overlap the two conductive busbars. However, the parts used in the overlapping process are relatively scattered, and the problem of the surface oxide layer of the conductive busbar itself needs to be considered. That is, before the overlapping process, the surface oxide layer of the conductive busbar must be removed as a whole to ensure the conductivity between the two conductive busbars after the overlapping is completed. However, the cost of removing the surface oxide layer of the conductive busbar is high and it is not feasible to carry out production. Utility Model Content
[0003] In view of the problems existing in the prior art, the main purpose of this utility model is to provide a conductive busbar connection component and connection structure.

[0016] The connecting part can be interference-fitted into the connecting hole of the first conductive busbar / second conductive busbar, so that the end face of the second flange part facing the connecting part in the axial direction abuts against the first conductive busbar / second conductive busbar;
[0017] When the connecting part and the second shaft part are axially connected to both sides of the second flange part, the second locking member can be axially inserted through the two conductive busbars and the conductive bushing from the side of the second conductive busbar / first conductive busbar away from the first conductive busbar / second conductive busbar to lock and connect with the first locking member.
[0018] When the connecting part and the second shaft part are sequentially connected to the same side of the second flange part, the second shaft part can pass through the two conductive busbars and the conductive bushing along the axial direction and be locked and connected with the second locking member.

[0020] When the connecting part and the second shaft part are sequentially connected to the same side of the second flange part along the axial direction, the outer wall of the second shaft part is also provided with an external thread to cooperate with the internal thread provided by the second locking member.

[0022] As a further description of the above technical solution, a second receiving groove is formed between the inner edge of the positioning tooth facing the connecting part and the outer edge of the connecting part facing the positioning tooth.
[0023] This utility model also provides a conductive busbar connection structure, which is formed by connecting the conductive busbar connection components as described above, and a first conductive busbar and a second conductive busbar respectively provided with connection holes, wherein the first conductive busbar and / or the second conductive busbar are formed with a surface oxide layer.
[0024] A conductive bushing is used to electrically connect the first conductive busbar and the second conductive busbar. It includes a first flange portion and a first shaft portion axially connected to one end of the first flange portion. The end face of the first flange portion facing the first shaft portion and the outer wall of the first shaft portion both protrude outward to form a plurality of first insertion portions.
[0025] When the first conductive busbar / second conductive busbar has a surface oxide layer, a first shaft portion of the conductive bushing is disposed in the connection hole of the first conductive busbar and / or the second conductive busbar, and the end face of its first flange portion facing the first shaft portion abuts against the first conductive busbar / second conductive busbar, and the plurality of first piercing portions pierce the surface oxide layer of the first conductive busbar / second conductive busbar; the second conductive busbar / first conductive busbar without a surface oxide layer abuts against the end face of the first flange portion away from the first shaft portion.
[0026] When both the first and second conductive busbars have surface oxide layers, the end faces of the first flange portions of the two conductive bushings facing away from their first shaft portions abut against each other, so that the two first shaft portions are respectively disposed in the connection holes of the two conductive busbars. The end face of any first flange portion facing the first shaft portion connected to it abuts against the corresponding conductive busbar, and the plurality of first piercing portions pierce the surface oxide layers of the two conductive busbars accordingly.
[0027] Based on the above technical solutions, the outstanding effects of this utility model are as follows:
[0028] The conductive busbar connection assembly for forming a conductive busbar connection structure provided by this utility model includes a conductive bushing for electrically connecting a first conductive busbar and a second conductive busbar. It includes a first flange and a first shaft axially connected to one end of the first flange. Multiple first insertion portions are formed on the end face of the first flange facing the first shaft and the outer wall of the first shaft. The first and second conductive busbars are respectively provided with connection holes. When the first or second conductive busbar has a surface oxide layer, only one conductive bushing is needed to achieve electrical connection between the two conductive busbars. Even if the first shaft of the conductive bushing is located in the connection hole of the first / second conductive busbar with a surface oxide layer, and the end face of the first flange facing the first shaft abuts against the conductive busbar, the multiple first insertion portions can pierce the surface oxide layer of the conductive busbar. Then, the other conductive busbar without an oxide layer directly abuts against the end face of the first flange away from the first shaft to achieve electrical connection. Electrical conduction is achieved between two spaced conductive busbars. If both busbars have surface oxide layers, two conductive bushings are required. The first flange portions of the two bushings are positioned so that their opposite ends (away from their first shaft portions) abut against each other. This allows the first shaft portions of the bushings to be positioned within the connection holes of the two busbars. Simultaneously, the end face of any first flange portion facing its connected first shaft portion abuts against the corresponding busbar. The multiple first insertion points formed by the bushings pierce the surface oxide layers of the two busbars, thus achieving electrical conduction. Therefore, in the process of achieving electrical conduction between two conductive busbars using conductive bushings, only one or two bushings need to be selected based on whether the busbars have surface oxide layers. Assembly is simple and quick. Since the surface oxide layers are directly pierced during assembly, there is no need to separately remove the surface oxide layers of the busbars, effectively reducing production costs.

[0045] Please see Figures 1 to 12 This utility model discloses a conductive busbar connection assembly, which includes:
[0046] A first conductive busbar 1 and a second conductive busbar 2 are respectively provided with connection holes 3, and the first conductive busbar 1 and / or the second conductive busbar 2 are formed with a surface oxide layer;
[0047] The conductive bushing 4 is used to electrically conduct the first conductive busbar 1 and the second conductive busbar 2. It includes a first flange portion 41 and a first shaft portion 42 connected axially to one end of the first flange portion 41. The end face of the first flange portion 41 facing the first shaft portion 42 and the outer wall of the first shaft portion 42 are both convexly formed with a plurality of first insertion portions 43.
[0048] When the first conductive busbar 1 / second conductive busbar 2 has a surface oxide layer, the first shaft portion 42 of the conductive bushing 4 can be disposed in the connection hole 3 of the first conductive busbar 1 and / or the second conductive busbar 2, and its first flange portion 41 abuts against the end face of the first shaft portion 42. The plurality of first piercing portions 43 can all pierce the surface oxide layer of the first conductive busbar 1 / second conductive busbar 2. The second conductive busbar 2 / first conductive busbar 1 without a surface oxide layer can abut against the end face of the first flange portion 41 away from the first shaft portion 42.
[0049] When both the first conductive busbar 1 and the second conductive busbar 2 have formed a surface oxide layer, the first flange portion 41 of the two conductive bushings 4 abuts against the end face of its first shaft portion 42, so that the two first shaft portions 42 can be respectively disposed in the connection hole 3 of the two conductive busbars. The end face of any first flange portion 41 facing the first shaft portion 42 connected to it can abut against the corresponding conductive busbar, and the multiple first piercing portions 43 can pierce the surface oxide layer of the two conductive busbars accordingly.
[0050] In the above configuration, the conductive bushing 4 is used to electrically connect the first conductive busbar 1 and the second conductive busbar 2. It includes a first flange portion 41 and a first shaft portion 42 connected axially to one end of the first flange portion 41. The end face of the first flange portion 41 facing the first shaft portion 42 and the outer wall of the first shaft portion 42 are both convexly formed with a plurality of first insertion portions 43. The first conductive busbar 1 and the second conductive busbar 2 are respectively provided with connection holes 3. When the first conductive busbar 1 or the second conductive busbar 2 has a surface oxide layer, only one conductive bushing 4 is needed to achieve electrical connection between the two conductive busbars. Even if the first shaft portion 42 of the conductive bushing 4 is located in the connection hole 3 of the first conductive busbar 1 / second conductive busbar 2 with a surface oxide layer, and the end face of the first flange portion 41 of the conductive bushing 4 facing the first shaft portion 42 abuts against the conductive busbar, the plurality of first piercing portions 43 can all pierce the surface oxide layer of the conductive busbar. Then, the other conductive busbar without surface oxide can directly abut against the end face of the first flange portion 41 away from the first shaft portion 42. The two conductive busbars are electrically connected when they are spaced apart. If both conductive busbars have surface oxide layers, two conductive bushings 4 are required. The first flange portions 41 of the two conductive bushings 4 are positioned so that their ends facing away from their first shaft portions 42 abut against each other. This allows the first shaft portions 42 of the two conductive bushings 4 to be respectively positioned within the connection holes 3 of the two conductive busbars. Simultaneously, the end face of any first flange portion 41 facing the first shaft portion 42 it connects to abuts against the corresponding conductive busbar. Consequently, the multiple first insertion portions 43 formed by the two conductive bushings 4 can respectively pierce the surface oxide layers of the two conductive busbars, achieving electrical connection between them. Therefore, in the process of electrically connecting the two conductive busbars using the conductive bushings 4, only one or two conductive bushings 4 need to be selected for assembly depending on whether the two conductive busbars have surface oxide layers. Assembly is simple and quick. Since the surface oxide layer is directly pierced during assembly, there is no need to consider removing the surface oxide layer of the conductive busbars separately, effectively reducing production costs.
[0051] Please see Figures 1 to 8Specifically, in the first embodiment, the first conductive busbar 1 and the second conductive busbar 2 are both horizontally placed and have vertically extending connection holes 3. The first conductive busbar 1 has a surface oxide layer, while the second conductive busbar 2 does not. When connecting the two conductive busbars, only one conductive bushing 4 is needed. The first shaft portion 42 of the conductive bushing is placed in the connection hole 3 of the first conductive busbar 1, and the end face of its first flange portion 41 facing the first shaft portion 42 abuts against the upper surface of the first conductive busbar 1. Thus, the first piercing on the first shaft portion 42 and the first flange portion 41 can pierce the surface oxide layer of the first conductive busbar 1. At the same time, the lower surface of the second conductive busbar 2 directly abuts against the end face of the first flange portion 41 away from the first shaft portion 42, so that the first conductive busbar 1 and the second conductive busbar 2 are electrically connected. There is no need to separately consider removing the surface oxide layer of the first conductive busbar 1.
[0052] Specifically, in this embodiment, a plurality of first piercing portions 43, formed by the outward protrusion of the first flange portion 41 toward the end face of the first shaft portion 42, are arranged around the first shaft portion 42, and their tips are axially away from the first flange portion 41, so that they can smoothly pierce the surface oxide layer of the first conductive busbar 1 when the first flange portion abuts against the first conductive busbar 1. It should be understood that, provided that the plurality of first piercing portions 43 formed by the outward protrusion of the first flange portion 41 toward the end face of the first shaft portion 42 can smoothly pierce the surface oxide layer, their shape can be appropriately varied, the main feature being that their tips are as sharp as possible.
[0053] Specifically, in this embodiment, the plurality of first inserts 43 formed by the protrusion of the first flange portion 41 toward the end face of the first shaft portion 42 extend radially along the first flange portion 41 and radiate outward with the first shaft portion 42 as the center.
[0054] Specifically, in this embodiment, when the first shaft portion 42 is disposed in the connection hole 3 of the first conductive busbar 1, a plurality of first insertion portions 43 formed by the outward protrusion of the outer wall of the first shaft portion 42 form an interference fit with the connection hole 3 of the first conductive busbar 1. When piercing the surface oxide layer of the inner wall of the connection hole 3, they can also provide anti-torsional and anti-pull-out forces. Specifically, in this embodiment, the plurality of first insertion portions 43 formed by the outward protrusion of the outer wall of the first shaft portion 42 are in a straight knurled shape. Of course, in other embodiments, they may also be in an oblique knurled shape or a polygonal shape, etc.
[0055] Specifically, in this embodiment, the conductive bushing 4 further includes a first receiving groove 44, which is formed by an inward recess at the connection between the first flange portion 41 and the first shaft portion 42. This groove allows the end face of the first flange portion 41 facing the first shaft portion 42 along the axial direction to fit as closely as possible to the first conductive busbar 1, thereby increasing the contact area. In addition, it allows excess deformable material of the first conductive busbar 1 (i.e., material that has undergone plastic deformation of the first conductive busbar 1 but cannot flow into the space between the multiple first inserts 43 formed by the outward protrusion of the outer wall of the first shaft portion 42) to flow in, thereby providing additional anti-pull-out force and making the connection between the conductive bushing 4 and the first conductive busbar 1 more stable.
[0056] Specifically, in this embodiment, in order to ensure the abutment relationship between the second conductive busbar 2 and the conductive bushing 4 to further stabilize and ensure the reliability of the current connection point, a locking unit for axially locking the two conductive busbars and the conductive bushing 4 is also provided. The locking unit includes a first locking member 5 and a second locking member 6. The first locking member 5 includes a second flange portion 51, a connecting portion 52, and a second shaft portion 53. The connecting portion 52 and the second shaft portion 53 are axially connected to the upper and lower sides of the second flange portion 51. The connecting portion 52 can be interference-fitted into the connecting hole 3 of the first conductive busbar 1 so that the end face of the second flange portion 51 facing the connecting portion 52 abuts against the lower surface of the first conductive busbar 1. The second locking member 6 can axially penetrate the two conductive busbars and the conductive bushing 4 from the upper side of the second busbar away from the first conductive busbar 1 and lock with the first locking member 5. The outer diameter of the second shaft portion 53 is smaller than the outer diameter of the second flange portion 51. This is to avoid other components in the installation / support area, making installation more reliable and convenient. At the same time, compared with the traditional integral cylinder (i.e., with a longer second flange portion 51), the weight can be greatly reduced.
[0057] Specifically, in this embodiment, the first locking member 5 is further provided with a threaded hole 54 that passes through the connecting part 52, the second flange part 51 and the second shaft part 53 along the axial direction, so as to cooperate with the external thread provided on the main body part 61 of the second locking member 6. The second locking member 6 is, for example, a hexagonal flange bolt, whose rod-shaped main body part 61 is provided with external thread.
[0058] Specifically, in this embodiment, the second flange portion 51 has a positioning tooth 55 protruding outward from the end face facing the connecting portion 52, and the positioning tooth 55 surrounds the outer periphery of the connecting portion 52. During its connection with the first conductive busbar 1, the first conductive busbar 1 will flow radially into the gap of the positioning tooth 55, so that the first conductive busbar 1 and the first locking member 5 are engaged with each other, thereby preventing relative rotation after the two are connected. Further, in this embodiment, the inner edge of the positioning tooth 55 is circular and the outer edge is serrated. When the first locking member 5 is connected to the first conductive busbar 1, the gap between two adjacent teeth is used to accommodate part of the material of the first conductive busbar 1, so that the first conductive busbar 1 and the first locking member 5 are tightly engaged with each other. Of course, in other embodiments, the outer edge of the positioning tooth 55 can also be set to other shapes, such as a circular outer edge, a rounded octagon, etc.
[0059] Specifically, in this embodiment, a second annular groove 56 is formed between the inner edge of the positioning tooth 55 toward the connecting portion 52 and the outer edge of the connecting portion 52 toward the positioning tooth 55. During the process of connecting the first locking member 5 to the first conductive busbar 1, some material of the first conductive busbar 1 will also flow into the second groove 56 under force to provide the force for the first locking member 5 to be pushed out from the first conductive busbar 1.
[0060] Specifically, in this embodiment, the first locking member 5 and the conductive bushing 4 are connected to the first conductive busbar 1 in stages by riveting (for example, they can be connected separately using a flat riveting tool with intermediate clearance holes). The installation order can be selected according to actual needs. However, considering that the conductive bushing 4 is generally made of copper, while the first locking member 5 is mostly made of carbon steel, and the strength of copper is generally lower than that of carbon steel, it is recommended to install the high-strength first locking member 5 first, so as to ensure that the connection quality of both to the first conductive busbar 1 meets production requirements. Then, it is further locked to the second conductive busbar 2 using the first locking member 5 and the second locking member 6 to ensure that the overall connection is stable and reliable. Of course, in other embodiments, in some special positions where riveting is difficult, the conductive bushing 4 and the first locking member 5 can also be installed on the first conductive busbar 1 as a whole by riveting. It should be understood that in this case, a riveting deformation part needs to be provided, but it does not affect the final effect of the two conductive busbars achieving electrical conduction through the puncture of the surface oxide layer.
[0061] Please see Figures 1 to 10Specifically, in the second embodiment, unlike the first embodiment, both the first conductive busbar 1 and the second conductive busbar 2 have surface oxide layers. Therefore, two conductive bushings 4 are used for connection. Specifically, the first flange portions 41 of the two conductive bushings 4 are arranged opposite to each other from the end faces of their first shaft portions 42, so that the first shaft portions 42 of the two conductive bushings 4 can be respectively disposed in the connection holes 3 of the two conductive busbars. At the same time, the end face of any first flange portion 41 facing the first shaft portion 42 connected to it can abut against the corresponding conductive busbar. Thus, the multiple first piercing portions 43 formed by the two conductive bushings 4 can respectively pierce the surface oxide layers of the two conductive busbars. While the first flange portions 41 of the two conductive bushings 4 are arranged opposite to each other from the end faces of their first shaft portions 42, they also abut against each other, thereby realizing the electrical conduction of the two conductive busbars. The connecting portion 52 of the first locking member 5 remains connected to the first conductive busbar 1. The second locking member 6 penetrates from top to bottom through the two conductive busbars and the two conductive bushings 4 to lock with the first locking member 5, further ensuring the stability and reliability of the current connection point. Of course, in other embodiments, depending on the actual installation situation, the connecting portion 52 of the first locking member 5 can be connected to the second conductive busbar 2, while the second locking member 6 penetrates from bottom to top through the two conductive busbars and the two conductive bushings 4 to lock with the first locking member 5.
[0062] Please see Figures 1 to 8 ,as well as Figure 11 and Figure 12 Specifically, in the third embodiment, unlike the first embodiment, although the first locking member 5 includes a second flange portion 51, a connecting portion 52, and a second shaft portion 53, the connecting portion 52 and the second shaft portion 53 are sequentially connected to the same side of the second flange portion 51. Therefore, the connecting portion 52 of the first locking member 5 is interference-fitted into the connecting hole 3 of the first conductive busbar 1, and when the end face of the second flange portion 51 facing the connecting portion 52 abuts against the lower surface of the first conductive busbar 1 along the axial direction, the second shaft portion 53 directly penetrates the first conductive busbar 1 upwards and continues upwards through the second conductive busbar 2.
