Description

Technical Field

[0001] This utility model relates to the field of circuit structure technology, specifically to a busbar structure. Background Technology

[0002] A busbar is an electrical connection device composed of multiple conductive bars, typically with rectangular, square, or circular cross-sectional shapes. These bars are arranged sequentially or in a crisscross pattern to achieve reliable connections between different conductors. Structurally, the conductive bars are isolated by plastic insulation material to ensure electrical safety. However, currently available busbar products suffer from several technical defects: First, their overall structural design is not compact enough, resulting in excessive size and space consumption; second, the performance of the insulation material needs improvement, and its insulation level cannot meet higher electrical standards; third, the product's withstand voltage is relatively low, limiting its application in high-voltage environments; furthermore, the installation process is complex and inconvenient, increasing construction difficulty; finally, the fixing method of the leads is not secure enough, making them prone to loosening during use and affecting the long-term stable operation of the equipment. Utility Model Content

[0003] Purpose of the utility model: The technical problem to be solved by this utility model is to provide a bus structure that solves the problem of low withstand voltage value of existing bus structures.

[0004] Technical solution

[0005] To solve the above problems, the technical solution provided by this utility model is as follows:

[0006] A bus structure includes a plurality of conductive busbars and a plastic insulator covering the plurality of conductive busbars. Each conductive busbar includes a bent structure located on the same plane and terminals located at both ends of the bent structure. The bent structures of the plurality of conductive busbars are stacked vertically to form an intersection point, and the stacked conductive busbars have a flat structure at the intersection point.

[0007] Furthermore, at least one of the superimposed conductive busbars is provided with a flat structure.

[0008] Furthermore, each of the superimposed conductive busbars is provided with a flat structure.

[0009] Furthermore, the flat structure of the superimposed conductive busbar is eccentrically positioned on the same side in the vertical direction.

[0010] Furthermore, the vertically intersecting conductive bars are divided into upper conductive bars and lower conductive bars. The flat structure at the intersection of the upper conductive bars is eccentrically positioned upwards, and the flat structure at the intersection of the lower conductive bars is eccentrically positioned downwards.

[0011] Furthermore, each of the bent structures of the conductive busbar is covered with a layer of plastic insulator, and a multi-layer structure of several stacked bent structures of the conductive busbar is covered with the plastic insulator.

[0012] Furthermore, the bottom layer of the multilayer structure of the plastic insulator is provided with a downwardly extending injection-molded boss.

[0013] Furthermore, the terminal is led out from the injection-molded boss.

[0014] Furthermore, the plastic insulator is provided with lead-out holes on the side of the injection-molded boss.

[0015] Beneficial effects

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0017] The technical solution provided by this utility model flattens the intersecting conductive bars at their intersection points, significantly increasing the spatial spacing and creepage safety distance of the conductive bars in the stacking direction. Simultaneously, in the stacking installation direction, the flattening process reduces the installation distance between the upper and lower conductive bars, effectively reducing the overall installation space required. From a thickness perspective, this optimized structural design significantly reduces the volume occupied by the entire conductive bar assembly. Furthermore, the plastic insulator structure incorporates injection-molded boss structures. These bosses not only significantly enhance the mechanical strength and stability of the terminals, but also provide convenient access for wiring connections through specially designed lead-out holes, making the entire connection process more convenient and reliable. This comprehensive structural optimization design ensures both reliable electrical performance and maximizes space utilization. Attached Figure Description

[0026] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] Combined with appendix Figure 1-4 A bus structure includes several interconnected conductive busbars 1 and a plastic insulator 6 covering the outside of the conductive busbars 1. The conductive busbars 1 are used to realize electrical connection between conductors. The conductive busbars 1 are designed to avoid stacking of the conductive busbar lines as much as possible, thereby reducing the occurrence of creepage. The conductive busbar 1 consists of bent lines located on the same plane and terminals 3 extending downward at both ends of the bent lines for connecting conductors.

[0029] The conductive busbar 1 is composed of a strip conductive structure with a square or circular cross-section. The two ends of the conductive busbar 1 extend downward to facilitate connection with different conductors. When the lines of different conductive busbars 1 overlap in the vertical direction, the conductive busbars 1 at the overlapping position need to be flattened to increase the distance between the conductive busbars 1 at the overlapping position, thereby increasing the spatial distance and creepage distance between the superimposed conductive busbars 1.

[0030] The conductors 1 can be preferentially designed by bending so that the lines between different conductors 1 can avoid each other through the bending structure on the same plane, thereby preventing creepage. However, since the width and length of the busbar 7 containing several conductors 1 are limited in actual manufacturing, it is not possible to fully avoid the multiple conductors 1 contained in one busbar 7 through the bending design on the same plane. Therefore, the conductors 1 in the busbar 7 will inevitably be stacked on top of each other.

[0031] The lines of at least two conductive busbars 1 stacked one above the other have intersection points in the vertical direction. There is a gap between the vertically intersecting conductive busbars 1. The conductive busbars 1 do not contact each other. The local structure of the conductive busbars 1 at the intersection position is a flat structure 2, so that the vertical distance of the conductive busbars 1 at the intersection position is greater than the vertical distance between the non-intersecting conductive busbars 1.

[0032] The flat structure 2 of the conductive busbar 1 can also be eccentrically set on the same side in the vertical direction. That is, the conductive busbars 1 that intersect in the vertical direction are divided into upper conductive busbars 8 and lower conductive busbars 9. The flat structure 2 at the intersection of the upper conductive busbars 8 can be eccentrically set upward, and the flat structure 2 at the intersection of the lower conductive busbars 9 can be eccentrically set downward, thereby further increasing the distance between the conductive busbars 1 at the intersection in the vertical direction.

[0033] The flat structure 2 on the vertically intersecting conductive busbar 1 can be set on either the upper conductive busbar 8 or the lower conductive busbar 9, or both the upper conductive busbar 8 and the lower conductive busbar 9, thereby achieving a better effect in preventing creepage.

[0034] Furthermore, by setting flat structures 2 on both the upper conductive busbar 8 and the lower conductive busbar 9, the distance between the upper conductive busbar 8 and the lower conductive busbar 9 at the intersection position is increased. Correspondingly, since the flattening process will lengthen the distance between the superimposed conductive busbars 1, the distance between the conductive busbars can be shortened in advance. The distance between the non-superimposed and intersecting conductive busbars does not affect each other, while the distance between the superimposed and intersecting conductive busbars is lengthened due to the flattening process. Thus, the shortening of the distance of the conductive busbars themselves can be offset by the distance lengthened by the flattening process. This can reduce the distance between the upper conductive busbar 8 and the lower conductive busbar 9, reduce the installation space, and reduce the volume of the entire conductive busbar in the thickness direction.

[0035] Multiple conductive bars 1 are covered with plastic insulators 6. The plastic insulators 6 are fixed to the conductive bars 1 by injection molding. Injection-molded insulators are set on conductive bars 1 located on different planes in the vertical direction. The injection-molded insulators are coated along the lines of the conductive bars 1. The plastic insulators 6 can form a multi-layer structure by stacking conductive bars 1 one on top of the other. The multi-layer structure of the plastic insulators 6 is a single structure, which is directly obtained by single injection molding.

[0036] The downward-extending portions on both sides of the conductive busbar 1 are the terminals 3 of the conductive busbar 1. The plastic insulator 6 covering the conductive busbar 1 has downward-extending injection-molded bosses 4 at each terminal 3 at both ends of the conductive busbar 1. The injection-molded bosses 4 can fix the terminals 3 of the conductive busbar 1 and prevent the angle of the terminals 3 at both ends of the conductive busbar 1 from changing. The plastic insulator 6 has lead-out holes 5 on the sides of the injection-molded bosses 4 used to fix the terminals 3 of the conductive busbar 1. The lead-out holes 5 facilitate wiring of the terminals 3.

[0037] The injection-molded boss 4 is located on the bottom surface of the bottom layer of the multi-layer structure of the plastic insulator 6 and extends downwards. The terminal 3 of the conductive bus 1 is led out from the injection-molded boss 4, which strengthens the structural strength of the terminal 3. The lead-out hole 5 runs through the entire multi-layer structure of the plastic insulator 6, facilitating wiring.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
