Description

Technical Field

[0001] This invention relates to a connection structure, and more particularly to a connection structure for connecting a power transmission bus. Background Technology

[0002] In the construction of large or high-tech factories, a stable and secure power supply is crucial for the operation of machines and equipment. Compared to cables, power transmission buses offer better space utilization and safety. Therefore, power transmission buses capable of transmitting large amounts of electricity are now widely used to replace traditional cables.

[0003] When installing power transmission buses, it is necessary to connect power buses from different sections to each other. As the area requiring power transmission bus installation expands, the number of power buses needed to be connected also increases. If the connection structure between two power transmission buses is overly complex, it will extend the installation time and increase installation costs. Furthermore, a poorly designed connection structure can lead to increased resistance or poor contact at the connection points, resulting in power loss and heat generation.

[0004] In summary, saving time in connecting power transmission buses and reducing the complexity of the connection structure will also be research goals for the connection structure of power transmission buses. Summary of the Invention

[0005] One objective of this invention is to provide a connection structure that is easy to install and avoids excessive resistance differences at the connection points.

[0006] This invention provides an electrical connection device comprising a first pressure plate, a second pressure plate, and a power bridging portion. The second pressure plate is disposed opposite to the first pressure plate. The power bridging portion is disposed between the first and second pressure plates. The power bridging portion includes an insulating structural member and a first bridging piece. The first bridging piece is disposed on a first surface of the insulating structural member, wherein the first bridging piece is electrically coupled to a first conductor piece and a second conductor piece. The first and second pressure plates are provided with compressive stress to the power bridging portion by a fixing member.

[0007] In some embodiments, the fastener is disposed outside the projection range of the first conductor sheet onto the plane where the first pressure plate is located.

[0008] In some embodiments, the first surface of the insulating structure has a recessed structure, and the first bridging piece is disposed within the recessed structure.

[0009] In some embodiments, the first conductor sheet is disposed within a first housing, the second conductor sheet is disposed within a second housing, a connection is provided between the first housing and the second housing, a first pressure plate is disposed on a first outer side of the connection, and a second pressure plate is disposed on a second outer side of the connection.

[0010] In some embodiments, the power bridging portion further includes: a second bridging piece disposed on a second surface opposite to the first surface of the insulating structure, the second bridging piece being electrically coupled to a third conductor piece and a fourth conductor piece.

[0011] In some embodiments, an insulating sheet is provided between the first conductor sheet and the third conductor sheet, and the insulating structure has a clearance end that extends into the space between the first conductor sheet and the insulating sheet.

[0012] In some embodiments, a colloid is present between the first bridging piece and the second bridging piece.

[0013] In some embodiments, the direction of the compressive stress is the normal direction of the first surface.

[0014] In some embodiments, the first pressure plate has at least one wing disposed on an outer surface of the first pressure plate.

[0015] In some embodiments, the outer surface of the first pressure plate has a first side and a second side opposite to each other, and the at least one wing is disposed on at least one of the first side and the second side.

[0016] In some embodiments, the first pressure plate has at least one gasket structure disposed on an inner surface of the first pressure plate facing the power bridging portion.

[0017] In some embodiments, the first pressure plate is composed of a separable first component and a second component, wherein the first component corresponds to the first housing and the second component corresponds to the second housing.

[0018] As described above, the fasteners apply compressive stress to the power bridging section by applying pressure to the first and second pressure plates. The first bridging piece within the power bridging section electrically couples the first and second conductor pieces, allowing power to be transmitted, for example, from the first conductor piece to the second conductor piece. This facilitates installation and avoids excessive resistance differences at the connection points. Attached Figure Description

[0060] like Figure 1A and Figure 1B As shown, the present invention provides an electrical connection device 1, comprising a first pressure plate 10, a second pressure plate 20, and a power bridging portion 30. The second pressure plate 20 is disposed opposite to the first pressure plate 10. Specifically, the first pressure plate 10 has a first inner surface 101, and the second pressure plate 20 has a second inner surface 201, the first inner surface 101 and the second inner surface 201 being opposite to each other, wherein the first inner surface 101 and the second inner surface 201 are exemplarily defined as surfaces facing the power bridging portion 30. The materials of the first pressure plate 10 and the second pressure plate 20 may be, but are not limited to, metals such as aluminum or plastic; however, the present invention is not limited to the materials of the first pressure plate 10 and the second pressure plate 20. The power bridging portion 30 is disposed between the first pressure plate 10 and the second pressure plate 20. The power bridging portion 30 includes an insulating structural member 31 and a first bridging piece 32. The first bridging piece 32 is disposed on the first surface 311 of the insulating structural member 31. It should be noted that, as Figure 1A and Figure 1B As shown, the power bridging section 30 may include multiple insulating structural members 31. The present invention is not limited to the number of insulating structural members 31. The material of the insulating structural members 31 may be, for example, but not limited to, non-conductive materials such as plastic or fiberglass. The material of the bridging piece 32 is a conductive material, preferably a highly conductive material such as copper, aluminum, or gold. It should be noted that the present invention is not limited to the materials of the insulating structural members 31 and / or the bridging piece 32.

[0061] like Figure 2 As shown, the first bridging piece 32 is electrically coupled to the first conductor piece 41 and the second conductor piece 51. Specifically, the first conductor piece 41 and the second conductor piece 51 are respectively the first power transmission bus and the second power bus. It should be noted that... Figure 2For clarity of the internal configuration, the housings and other non-essential details of the first power transmission bus 100 and the second power bus 200 are omitted. Power on the first conductor sheet 41 can be transmitted to or received by the second conductor sheet 51 via the first bridging piece 32. Electrical coupling can be achieved, for example, but not limited to, direct contact between the first bridging piece 32 and both the first and second conductor sheets 41 and 51. In this embodiment, the first pressure plate 10 and the second pressure plate 20 provide compressive stress F to the power bridging portion 30 via a fastener 60. Specifically, the fastener 60 can be, for example, but not limited to, fasteners, clamps, or screws and nuts, etc., for fixing and / or locking. Figure 2 In the embodiments, the fixing member 60 includes a screw 61 and a nut 62. It should be noted that the present invention is not limited to the number of fixing members 60; the number of fixing members 60 is preferably even so that the compressive stress F can be evenly distributed to the power bridging portion 30. Furthermore, preferably, the direction of the compressive stress F is the normal direction of the first surface 311, and the range of action is preferably within the projection range of the first bridging piece 32 onto the first surface 311. The present invention uses the fixing member 60 to fix the first pressure plate 10 and the second pressure plate 20 and provides compressive stress F to the power bridging portion 30, thereby increasing or tightening the contact area between the first bridging piece 32 and the first conductor piece 41 and the second conductor piece 51, improving the efficiency of power transmission and reducing the probability of poor contact.

[0062] In one embodiment, the power bridging section 30 further includes a second bridging piece 33 disposed on a second surface 312 of the insulating structure 31 opposite to the first surface 311. The second bridging piece 33 is electrically coupled to the third conductor piece 42 and the fourth conductor piece 52. Specifically, bridging pieces 32 and 33 can be disposed on both the first surface 311 and the second surface 312 of the insulating structure 31 to guide the power transmitted on different conductor pieces. In addition, the third conductor piece 42 and the fourth conductor piece 52 can also be electrically coupled through bridging pieces 35 on another set of insulating structures 34. Electrical coupling through multiple sets of bridging pieces 33 and 35 can reduce the resistance at the connection point and avoid risks such as poor contact or open circuit.

[0063] like Figure 3AAs shown, a first conductor sheet 41 is disposed within a first housing 110, and a second conductor sheet 51 is disposed within a second housing 210. A connection 300 is located between the first housing 110 and the second housing 210. A first pressure plate 10 is disposed on the first outer side 301 of the connection 300, and a second pressure plate 20 is disposed on the second outer side 302 of the connection 300. Specifically, the first power transmission bus 100 includes a first housing 110 and the first conductor sheet 41 within the first housing 110. The second power transmission bus 200 includes a second housing 210 and the second conductor sheet 51 within the second housing 210. The first power transmission bus 100 and the second power transmission bus 200 are connected via an electrical connection device 1. The connection 300 is located at the intersection of one end 1001 of the first power transmission bus 100 and one end 2001 of the second power transmission bus 200. The first outer side 301 and the second outer side 302 are exemplarily defined as the sides facing away from the power bridging portion 30. An embodiment in which the first pressure plate 10 and the second pressure plate 20 are disposed on the outer sides 301 and 302 of the connection 300 can be referred to. Figure 3B Specifically, the first pressure plate 10 and the second pressure plate 20 provide compressive stress to the first housing 110 and the second housing 210 to combine the first power transmission bus 100 and the second power transmission bus 200. With this arrangement, the first housing 110 and the second housing 210 can be directly used at the connection 300 between the first power transmission bus 100 and the second power transmission bus 200, thus saving the time of setting up a protective shell at the connection 300.

[0064] The fastener 60 can fix the first pressure plate 10, the second pressure plate 20, the first housing 110, and / or the second housing 210. For example... Figure 3A and Figure 3B In this embodiment, the first pressure plate 10, the second pressure plate 20, the first housing 110, and / or the second housing 210 may have corresponding through holes, so that the screw 61 can pass through the through hole h11 of the first pressure plate 10, the through hole h21 of the first housing 110, and the through hole h31 of the second pressure plate 20, and then be secured with a nut 62, thereby stabilizing the first pressure plate 10, the second pressure plate 20, and the first housing 110. Similarly, the screw 61 can also pass through the through hole h12 of the first pressure plate 10, the through hole h22 of the second housing 210, and the through hole h32 of the second pressure plate 20, and then be secured with a nut 62 to stabilize the first pressure plate 10, the second pressure plate 20, and the second housing 210. It should be noted that... Figure 3A and Figure 3BThe placement of the fastener 60 is merely an example and is not intended to limit the placement or number of fasteners 60 in this invention. This placement not only provides compressive stress F to the power bridging portion 30 but also strengthens the connection between the first housing 110 and the second housing 210, preventing breakage or disengagement of the connection between the first housing 110 and the second housing 210 from the connection point 300. Furthermore, in this embodiment, the fastener 60 is preferably placed outside the projection range P of the first conductor sheet 41 and / or the second conductor sheet 51 onto the plane containing the first pressure plate 10 or the second pressure plate 20. Therefore, the fastener 60 can be prevented from passing through the conductor sheets 41 and 51. In other words, the conductor sheets 41 and 51 do not need to have through holes to fix the first pressure plate 10, the second pressure plate 20, the first housing 110, and / or the second housing 210. Therefore, the resistance value of the conductor sheets 41 and 51 is not affected by the fastener 60, which can, for example but not limited to, reduce heat generation or power transmission losses.

[0065] In one embodiment, such as Figure 4 As shown, the first surface 311 of the insulating structural member 31 has a recessed structure 313, and the first bridging piece 32 is disposed within the recessed structure 313. Specifically, the shape and size of the recessed structure 313 match the first bridging piece 32. When the first bridging piece 32 is disposed on the first surface 311, the first bridging piece 32 can be embedded within the recessed structure 313. This can, for example, but not limited to, prevent the first bridging piece 32 from slipping or shifting, thus reducing the complexity and time required for installation.

[0066] In one embodiment, such as Figure 5 As shown, an insulating sheet 70 is provided between the first conductor sheet 41 and the third conductor sheet 42. The insulating sheet is made of, but is not limited to, fiberglass or Mylar gaskets. The insulating sheet 70 is used to isolate the first conductor sheet 41 and the third conductor sheet 42, preventing short circuits or electromagnetic interference between them. The insulating structure 31 has a clearance end 315 that extends between the first conductor sheet 41 and the insulating sheet 70. Specifically, there is a gap G between the first conductor sheet 41 and the insulating sheet 70, and the clearance end 315 extends into the gap G. It should be noted that... Figure 5 This is merely illustrative and not intended to limit the arrangement of the clearance end 315. In one embodiment, the clearance end 315 may also extend between the third conductor sheet 42 and the insulating sheet 70. By extending the clearance end 315 into the gap G between the first conductor sheet 41 and the insulating sheet 70, for example, but not limited to, the arrangement of the power bridging portion 30 can be made more stable.

[0067] In one embodiment, the first pressure plate 10 and the second pressure plate 20 may each be provided with wings. For example... Figure 6Taking the first pressure plate 10 as an example, the wing 15 is an outwardly protruding structure on the outer surface 102 of the first pressure plate 10, and the included angle θ between the wing 15 and the outer surface 102 is approximately 90 degrees (which may be adjusted depending on the installation state or process). The wing 15 is preferably disposed on the side of the outer surface 102 of the first pressure plate 10. Specifically, the outer surface 102 of the first pressure plate 10 has a first side 1021, a second side 1022, a third side 1023, and a fourth side 1024. The wing 15 may be disposed at at least one of the first side 1021, the second side 1022, the third side 1023, and the fourth side 1024. Preferably, the wing 15 is disposed on opposite sides (e.g., on both sides). Figure 6 (As shown on the first side 1021 and the third side 1023). However, the present invention is not limited thereto. Figure 6 For example, the number of wings 15 can be four, and they are respectively provided at the first side 1021, the second side 1022, the third side 1023, and the fourth side 1024. By providing wings on the first pressure plate 10 and the second pressure plate 20, the structural strength of the first pressure plate 10 and the second pressure plate 20 can be improved, or force application points or support points can be provided for the installer to handle / install, but the purpose of providing wings is not limited to the above examples.

[0068] In one embodiment, the first pressure plate 10 and the second pressure plate 20 may each be provided with a gasket structure. For example... Figures 7A to 7C Taking the first pressure plate 10 as an example, a gasket structure 16 can be provided on the inner surface 101 of the first pressure plate 10. When the first pressure plate 10 and the second pressure plate 20 are fixedly installed on both sides of the connection 300, the gasket structure 16 will be located between the first outer side 301 of the connection 300 and the inner surface 101 of the first pressure plate 10 (e.g., Figure 7B and Figure 7C (As shown). The gasket structure 16 can, for example, serve as a buffer between the first pressure plate 10 and / or the housings 110 and 210 of the power transmission busbars 100 and 200, or to distribute the positive force provided by the first pressure plate 10 evenly across the housings 110 and 210 of the power transmission busbars 100 and 200, but is not limited thereto. The gasket structure 16 can be arranged as follows: Figure 7AAs shown, a through hole 103 is created in the first pressure plate 10 to connect the inner surface 101 and the outer surface 102. A gasket structure 16 is fixed to the inner surface 101 by a fixing material 161. The fixing material 161 and the gasket structure 16 can be rubber, plastic, or other suitable materials. It should be noted that the fixing material 161 and the gasket structure 16 are not necessarily two separate components. When the process allows (e.g., injection molding or mold), the fixing material 161 and the gasket structure 16 can be an integral structure. Furthermore, the present invention is not limited to the method of the gasket structure 16 being disposed on the inner surface 101. For example, the gasket structure 16 can also be disposed between the first outer surface 301 of the connection 300 and the inner surface 101 of the first pressure plate 10 by means of adhesion or directly providing compressive stress. In addition, although... Figures 7A to 7C In the example, the number of gasket structures 16 is four; however, the present invention is not limited to the number of gasket structures 16, and any person skilled in the art can make a decision based on this. Figure 7A and Figure 7B Any adjustments to the number of gasket structures 16 in the examples described herein should fall within the scope of this invention.

[0069] In one embodiment, the first pressure plate 10 and the second pressure plate 20 can be separated into two components. Taking the first pressure plate 10 as an example, as follows... Figure 8A and Figure 8B The first pressure plate 10 can be disassembled into a first component 17 and a second component 18. The first component 17 and the second component 18 can be combined into the first pressure plate 10 using fasteners such as screws and nuts. Specifically, as follows... Figure 8A As shown, one side 171 of the first component 17 and one side 181 of the second component 18 each have wings 172 and 182. The wings 172 and 182 each have through holes 1721, 1722, 1821, and 1822 positioned opposite each other. The fastener can use the through holes 1721, 1821, 1722, and 1822 to connect and fix the first component 17 and the second component 18 (e.g., ...). Figure 8B (As shown). In this embodiment, as Figure 8C The first component 17 corresponds to the first power transmission busbar 100, and the second component 18 corresponds to the second power transmission busbar 200. Similar to the first pressure plate 10, the second pressure plate 20 can also be divided into two separable components, corresponding to the first power transmission busbar 100 and the second power transmission busbar 200 respectively. With the separable first component 17 and second component 18, when the first power transmission busbar 100 and the second power transmission busbar 200 need to be separated or installed, the first pressure plate 10 and / or the second pressure plate 20 do not need to be completely removed; only the corresponding components need to be removed / installed. This achieves convenience during installation / removal and flexibility in construction.

[0070] In one embodiment, the interior of the electrical connection device can be filled with an insulating and waterproof colloid such as silicone, silicone resin, or epoxy resin. Specifically, the electrical bridging portion of the electrical connection device can fill the gaps between or around the bridging pieces with the aforementioned colloid. This can improve the waterproof and dustproof performance of the electrical connection device or enhance its structural strength.

[0071] The present invention has been described by the above-described embodiments; however, these embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. Conversely, modifications and equivalents within the spirit and scope of the invention are all included within the scope of the present invention.
