Description

Technical Field

[0001] The utility model relates to the technical field of busbar connection, in particular to a busbar connector. Background Art

[0002] The compact busbar is an indispensable part in the process of power transmission and distribution. Due to the compact arrangement of the busbar conductors in the compact busbar, with overall heat dissipation, compact structure, small occupied space and convenient use, it is a safe and reliable power distribution system and is widely used as a high-current and efficient power transmission and distribution system in large commercial plazas, real estate projects, hospitals, industrial factories and other projects. When installing the compact busbar, connectors are required to connect between each section of the busbar. During the process of transmitting electric energy, the busbar may come into contact with water or dust, which may cause a short circuit between the busbars.

[0003] At the current stage, in the busbar connector, two end plates and a plurality of conductive connecting plates for clamping the busbar conductors located between the two end plates are included in the connector body. The two end plates and the plurality of conductive connecting plates are movably penetrated together by an insulating bolt. The two end plates are respectively in contact with the positioning plates located outside the conductive connecting plates. As shown in the A part of Figure 1 a positioning protrusion is formed on the inner side of the end plate, and positioning is achieved only by relying on the positioning protrusion and the conductive connecting plate.

[0004] However, when the end plate is too long or deformed and abuts against the positioning plate of the busbar, it will cause the end copper bar extending into the connector to be too short; the original external lap joint may have deviations in the lap joint surface due to other factors such as the deformation of the side plate, and the lap joint surface is too small, resulting in heat generation of the connector and affecting its performance. Summary of the Utility Model

[0005] Aiming at the defects in the prior art, the utility model provides a busbar connector to solve the problem that positioning is achieved through the positioning protrusion of the end plate and the side plate at present, resulting in a too small lap joint surface, which will cause heat generation of the connector and affect its performance.

[0006] A busbar connector provided by the utility model for connecting a compact busbar includes:

[0007] Spacer blocks, which are arranged at intervals;

[0008] Connector busbars, which are arranged on the front and back surfaces of the spacer blocks, the connector busbars are arranged at intervals, and positioning convex packages are arranged on the connector busbars;

[0009] Insulating bolts, which are penetrated between the spacer blocks and the connector busbars;

[0010] The conductive connection bar is arranged between the conductive bars of the connector. The conductive connection bar is arranged on both sides of the conductive bars of the connector. The conductive connection bar is electrically connected to the conductive bars of the connector, and the end of the conductive connection bar abuts against the positioning convex hull.

[0011] As can be seen from the above technical solution, for a busbar connector provided by the present utility model, when the end copper bar of the busbar is connected to the connector, due to the positioning convex hull on the conductive bar of the connector, the end copper bar of the busbar can be quickly installed in the predetermined position, which not only ensures the copper bar lapping area between the busbar and the connector, but also avoids other problems that may be caused by the length of the end plate.

[0012] Optionally, the positioning convex hull includes a first convex hull and a second convex hull. The first convex hull is arranged on the lower surface of the conductive bar of the connector and on both sides of the insulating bolt; the second convex hull is arranged on the upper surface of the conductive bar of the connector and on both sides of the insulating bolt; the straight lines where the first convex hull and the second convex hull on the same side are located are arranged parallel to each other.

[0013] Optionally, both the first convex hull and the second convex hull are two. The first convex hulls on both sides of the conductive bar of the connector are arranged diagonally, and the second convex hulls on both sides of the conductive bar of the connector are arranged diagonally; the diagonals where the first convex hull and the second convex hull are located are arranged staggeredly.

[0014] As can be seen from the above technical solution, the diagonal arrangement avoids contact between the first convex hull and the second convex hull and mutual interference; at the same time, the diagonals where the first convex hull and the second convex hull are located are arranged staggeredly, and the conductive connection bar is limited on both sides.

[0015] Optionally, the sum of the height of the first convex hull and the second convex hull is less than the thickness of the conductive connection bar.

[0016] As can be seen from the above technical solution, there is a gap between the first convex hull and the second convex hull located above and below the conductive connection bar respectively. While realizing the quick positioning of the conductive connection bar, the electrical isolation of the conductive bar of the connector is ensured, and mutual interference is avoided.

[0017] Optionally, it further includes an end plate and a positioning plate. The end plate is arranged on the outside of the connector; a sealing groove is arranged on the end plate, a sealing strip is arranged in the sealing groove, and the positioning plate and the end plate clamp the sealing strip.

[0018] Adopting the above technical solution, the present application has the following technical effects:

[0019] The busbar connector provided by the present utility model, when the end copper bar of the busbar is connected to the connector, due to the positioning convex bumps on the conductive bar of the connector, the conductive connection bar can be quickly installed in the established position, which not only ensures the copper bar lap area between the busbar and the connector, but also avoids other problems that may be caused by the length of the end plate.

For example, it may be a fixed connection, a detachable connection, or integrated; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal connection of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0032] In this application, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature.

[0033] As Figures 1-4 shown, a busbar connector 2 provided in this embodiment is used to connect a compact busbar 1 and includes partition blocks 21, connector busbars 22, insulating bolts 23, and conductive connection bars 24. The partition blocks 21 are arranged at intervals; the connector busbars 22 are arranged on the front and back surfaces of the partition blocks 21, and the connector busbars 22 are arranged at intervals. Positioning bumps 221 are provided on the connector busbars 22; the insulating bolts 23 are passed through between the partition blocks 21 and the connector busbars 22; the conductive connection bars 24 are arranged between the connector busbars 22, the conductive connection bars 24 are arranged on both sides of the connector busbars 22, the conductive connection bars 24 are electrically connected to the connector busbars 22, and the ends of the conductive connection bars 24 are abutted against the positioning bumps 221.

[0034] For the busbar connector 2 provided in this embodiment, when the connector busbar 22 at the end of the busbar is connected to the connector 2, due to the positioning bumps 221 on the connector busbar 22, the connector busbar 22 can be quickly installed in the predetermined position, which not only ensures the copper bar lap area between the busbar and the connector, but also avoids other problems that may be caused by the length of the end plate.

[0035] The positioning convex hull 221 includes a first convex hull 221a and a second convex hull 221b. The first convex hull 221a is disposed on the lower surface of the connector conductive row 22, and the second convex hull 221b is disposed on the upper surface of the connector conductive row 22. The straight lines where the first convex hull 221a and the second convex hull 221b on the same side are located are arranged parallel to each other.

[0036] As Figures 4-5 shown, there are two first convex hulls 221a and two second convex hulls 221b. The first convex hulls 221a on both sides of the connector conductive row 22 are diagonally arranged, and the second convex hulls 221b on both sides of the connector conductive row 22 are also diagonally arranged; the height of the first convex hull 221a plus the second convex hull 221b is less than the thickness of the conductive connection row 24. There is a gap between the first convex hull 221a and the second convex hull 221b respectively above and below the conductive connection row 24, which while achieving the rapid positioning of the conductive connection row 24, ensures the electrical isolation of the connector conductive row 22 and avoids mutual interference.

[0037] It can be understood that Figures 4-5 the setting positions of the first convex hull 221a and the second convex hull 221b in are not specifically limited, and the two first convex hulls 221a and the two second convex hulls 221b can also be arranged at opposite diagonals.

[0038] Specifically, the first convex hull 221a and the second convex hull 221b are arranged in an interleaved manner to avoid contact between the first convex hull 221a and the second convex hull 221b and avoid mutual interference. At the same time, the diagonals where the first convex hull 221a and the second convex hull 221b are located are interleaved, and the limiting of the conductive connection row 24 is realized on both sides.

[0039] As Figure 1 shown, the busbar connector 2 further includes an end plate 3 and a positioning plate 4. The end plate 3 is disposed outside the busbar connector 2; a sealing groove 5 is provided on the end plate 3, and a sealing strip is provided in the sealing groove 5. The positioning plate 4 and the end plate 3 clamp the sealing strip. When the end plate 3 is abutted against the positioning plate 4 of the busbar 1 through the insulating bolt 23, the end plate 3 and the positioning plate 4 clamp the sealing strip with each other, thereby preventing water or dust from entering the busbar 1 and achieving a sealing effect.
