[0041] Embodiment 1
[0042] As Figure 1 and Figure 2 shown, this embodiment provides a pressed busbar. The pressed busbar includes an insulating film 2 and a conductive plate 1. The conductive plate 1 includes a conductive plate body 11 and pins 12. Insulating films 2 are stacked on both sides of the conductive plate body 11 along the thickness direction of the conductive plate body 11. The conductive plate body 11 includes a connected body portion 111 and a bent portion 112, and pins 12 are provided extending outward from the edge of the bent portion 112. For the pressed busbar provided in this embodiment, by providing a bent portion 112 on the conductive plate body 11 and providing pins 12 extending outward from the edge of the bent portion 112, electrical connection with corresponding electrical components is achieved through the pins 12, which is more convenient for routing and facilitates the electrical connection between the pins 12 and the corresponding electrical components.
[0043] It should be noted that the laminated busbar provided in this embodiment includes at least two conductive plates 1. The at least two conductive plates 1 are stacked, and an insulating film 2 is clamped between two adjacent stacked conductive plates 1, so that the two conductive plates 1 can share one insulating film 2. It should be noted that in the drawings of this embodiment, only one conductive plate 1 is shown for illustration. The laminated busbar provided in this embodiment can be provided with two stacked conductive plates 1, or more conductive plates 1 can be provided. The specific number of conductive plates 1 can be set according to requirements, as long as it is not less than two.
[0044] Optionally, in this embodiment, the size of the insulating film 2 is larger than the size of the conductive plate body 11, and the edge of the insulating film 2 extends out of the edge of the conductive plate body 11, so that a part of the insulating film 2 is stacked on the pin 12. The above setting enables the edges of two adjacent insulating films 2 to fit together, thereby forming a sealed edge, so as to better protect the conductive plate body 11 and ensure the insulation effect on the outer surface of the conductive plate body 11.
[0045] Optionally, in this embodiment, as Figure 1 and Figure 2 shown, the bending part 112 includes a first bending plate 1121 and a second bending plate 1122 connected at an angle. Among them, the first bending plate 1121 is connected to the body part 111 at an angle, and the edge of the second bending plate 1122 extends out to be provided with a pin 12. Optionally, in this embodiment, the first bending plate 1121 is perpendicularly connected to the body part 111. In other embodiments, the connection angle between the first bending plate 1121 and the body part 111 can be set according to requirements. Optionally, in this embodiment, the first bending plate 1121 and the second bending plate 1122 are perpendicularly connected, and the second bending plate 1122 extends away from the body part 111. In other embodiments, the first bending plate 1121 and the second bending plate 1122 can also be connected at other angles.
[0046] Optionally, in this embodiment, as Figure 1 and Figure 2 shown, a plurality of pins 12 are spaced apart from each other on the edge of the second bending plate 1122, thus meeting the wiring requirements of the laminated busbar.
[0047] It should be noted that after insulating films 2 are attached to both opposite sides of the conductive plate body 11 along the thickness direction of the conductive plate body 11, and then the conductive plate 1 is bent. Since the size of the bending part 112 formed by bending the conductive plate 1 is small, especially the extension size of the second bending plate 1122 is small, the bending stress received at the bending part 112 is large, which easily causes the insulating film 2 stacked at the bending part 112 to blister and separate from the conductive plate body 11, greatly reducing the stability and reliability of the attachment of the insulating film 2 to the conductive plate body 11.
[0048] To solve the above problems, as Figure 1 and Figure 2 shown, in this embodiment, a stress relief portion 21 is provided on the insulating film 2 stacked at the bending portion 112. By providing the stress relief portion 21 on the insulating film 2 stacked at the bending portion 112, the bending stress on the insulating film 2 at the bending portion 112 during the bending operation of the conductive plate 1 is effectively reduced, and the problem of blistering and separation of the insulating film 2 caused by excessive bending stress on the insulating film 2 stacked at the bending portion 112 is avoided, improving the stability and reliability of the stacking and attachment of the insulating film 2 on the conductive plate body 11.
[0049] Optionally, in this embodiment, as Figure 1 and Figure 2 shown, the stress relief portion 21 is a stress relief opening. The lead 12 is correspondingly provided with two stress relief openings arranged at intervals along the first direction (the width direction marked in the figure). The lead 12 is located between the two stress relief openings, and the opening of the stress relief opening faces the edge of the insulating film 2. The above setting makes the insulating film 2 no longer closely attached to both sides of the lead 12, effectively relieving the bending stress on the insulating film 2, especially the bending stress on the insulating film 2 at the second bending plate 1122, and improving the stability and reliability of the stacking and attachment of the insulating film 2 on the conductive plate body 11.
[0050] Optionally, in this embodiment, as Figure 1 and Figure 2 shown, the end of the stress relief opening far from the opening extends to the edge of the bending portion 112. The above setting not only avoids the exposure of the conductive plate body 11, ensures the insulation effect of the outer surface of the conductive plate body 11, but also effectively relieves the bending stress on the insulating film 2 at the bending portion 112, improving the stability and reliability of the stacking and attachment of the insulating film 2 on the conductive plate body 11.
[0051] This embodiment also provides an electrical device, which includes an electrical component and the above-mentioned pressed busbar, and the electrical component is electrically connected to the lead 12. The electrical device provided in this embodiment is more convenient for wiring and electrically connecting the lead 12 to the corresponding electrical component by applying the above-mentioned pressed busbar to be electrically connected to the electrical component.
[0052] Optionally, in this embodiment, the electrical device can be a transformer cabinet, a switch cabinet, a reactor, etc. This embodiment does not limit the specific form of the electrical device.
[0053] Embodiment 2
[0054] The pressed busbar provided in this embodiment is basically the same as that in Embodiment 1. The difference between the pressed busbar provided in this embodiment and that in Embodiment 1 is as follows:
[0055] AsFigure 3 and Figure 4 As shown in Figure 4 , in this embodiment, a cutting hole 22 is further provided on the insulating film 2 stacked at the bending portion 112, and the cutting hole 22 communicates with two stress relief openings corresponding to the pin 12. With the above arrangement, the insulating film 2 stacked on the pin 12 is removed, the area of the removed insulating film 2 is increased, and the bending stress on the insulating film 2 at the bending portion 112 is further relieved, thereby further improving the stability and reliability of the insulating film 2 stacked and attached on the conductive plate body 11.
[0056] Optionally, in this embodiment, as Figure 3 and Figure 4 shown, the first end of the cutting hole 22 extends to the edge of the insulating film 2, and the second end of the cutting hole 22 extends to the connection portion between the first bending plate 1121 and the second bending plate 1122. With the above arrangement, the portion of the insulating film 2 that is greatly affected by the bending stress is effectively removed, avoiding affecting the overall attachment effect of the insulating film 2, and improving the overall stacking and attachment effect of the insulating film 2 on the conductive plate body 11.
[0057] Optionally, in this embodiment, as Figure 3 and Figure 4 shown, along the first direction (the width direction marked in the figure), the first side of the cutting hole 22 is flush with the edge of one of the stress relief openings of the pin 12, and the second side of the cutting hole 22 is flush with the edge of the other stress relief opening of the pin 12. With the above arrangement, on the basis of effectively removing the portion of the insulating film 2 that is greatly affected by the bending stress, the insulating protection effect on the conductive plate body 11 is ensured as much as possible.
[0058] The electrical device provided in this embodiment, by applying the above-mentioned press-fitting busbar to electrically connect with the electrical component, is more convenient for wiring and facilitates the electrical connection between the pin 12 and the corresponding electrical component.
[0059] Embodiment Three
[0060] The press-fitting busbar provided in this embodiment is basically the same as that in Embodiment One. The difference between the press-fitting busbar provided in this embodiment and that in Embodiment One is as follows:
[0061] As Figures 5 to 7 shown, in this embodiment, the stress relief portion 21 is a stress relief hole, the stress relief hole extends along the first direction (the width direction marked in the figure), and the stress relief hole is located at the connection portion between the pin 12 and the bending portion 112. With the above position setting of the stress relief hole, the bending stress on the insulating film 2 is effectively released, thereby improving the stability and reliability of the insulating film 2 stacked and attached on the conductive plate body 11.
[0062] Optionally, in this embodiment, the first direction is the width direction of the pin 12, and the extension length of the stress relief hole is not less than the width of the pin 12, thereby ensuring the stress relief effect of the insulating film 2 on the bending stress received.
[0063] For the electrical device provided in this embodiment, by applying the above-mentioned laminated busbar to be electrically connected to the electrical component, it is more convenient for wiring and for the pin 12 to be electrically connected to the corresponding electrical component.
[0064] Embodiment Four
[0065] The laminated busbar provided in this embodiment is basically the same as that in Embodiment One. The difference between the laminated busbar provided in this embodiment and that in Embodiment One lies in:
[0066] As Figures 8 to 10 shown, in this embodiment, the stress relief portion 21 is a stress relief hole, and the stress relief hole extends in the first direction (the width direction marked in the figure), and the stress relief hole is located at the connection between the first bending plate 1121 and the second bending plate 1122. The above-mentioned position setting of the stress relief hole enables the bending stress received by the insulating film 2 to be effectively released, thereby improving the stability and reliability of the insulating film 2 stacked and attached on the conductive plate body 11.
[0067] Optionally, in this embodiment, the first direction is the width direction of the pin 12, and the extension length of the stress relief hole is not less than the width of the pin 12, thereby ensuring the stress relief effect of the insulating film 2 on the bending stress received.
[0068] For the electrical device provided in this embodiment, by applying the above-mentioned laminated busbar to be electrically connected to the electrical component, it is more convenient for wiring and for the pin 12 to be electrically connected to the corresponding electrical component.
[0069] Obviously, the above-mentioned embodiments of the present application are merely examples for clearly illustrating the present application, rather than limiting the implementation manners of the present application. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here.
