Abstract
Description
Technical Field
[0001] Embodiments of the present disclosure generally relate to the technical field of electrical equipment, and more specifically, to an electrical connector and a DC bus duct. Background Art
[0002] Conventional bus ducts are usually used in AC scenarios. If the bus duct is used in DC scenarios, one of the solutions is to connect the A-phase busbar and the B-phase busbar in parallel as one pole, and connect the C-phase busbar and the neutral busbar in parallel as the other pole.
[0003] In order to apply AC bus duct to DC scenarios, conventional DC bus ducts are usually equipped with flanges at both ends of its loop. However, when power is taken from the plug interface in the middle of the loop to supply power to loads such as plug-in boxes, it is easy to cause load or current imbalance on the same-pole busbar downstream of the loop.

[0006] According to the embodiments of the present disclosure, the conductor is integrally formed or includes at least a pair of conductive parts. When one busbar in the same-polarity busbar is in contact with one side of the conductor and the other busbar in the same-polarity busbar is in contact with the other side of the conductor, since the conductor can connect the busbars on both sides thereof, the busbars in the same polarity can be connected in parallel again at the position of the electrical connector through the conductor, that is, the electrical connector 100 can achieve a convergence effect, thereby solving the problem of load or current imbalance of the busbars in the same polarity downstream of the loop.

[0027] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

The term "based on" means "based at least in part on". The terms "an example embodiment" and "an embodiment" mean "at least one example embodiment".

[0029] As described above, conventional DC bus ducts are usually provided with flanges at both ends of the loop to connect the A-phase busbar and the B-phase busbar in parallel, and the C-phase busbar and the neutral busbar in parallel. However, when taking power at the plug interface in the middle of the loop to supply power to loads such as plug-in boxes, due to differences in conductor lengths of busbars of the same polarity, differences in contact resistance when electrical connectors are connected, and differences in the length of the power-taking loops of the plug-in boxes, the load or current of the busbars of the same polarity downstream of the loop is unbalanced. The embodiments of the present disclosure provide an electrical connector 100 and a DC bus duct to at least partially solve the above problems. In the following, the present invention will be combined with the present invention to provide a DC bus duct with a plurality of different types of connectors. Figures 1 to 9 The principles of the present disclosure are described.
[0030] Figure 1 A cross-sectional view of an electrical connector 100 according to some embodiments of the present disclosure is shown. Figure 2 FIG. 2 shows an exploded view of an electrical connector 100 according to some embodiments of the present disclosure. Figure 1 to Figure 2 As shown, the electrical connector 100 described herein generally includes a pair of conductors 10 , a first insulating assembly 20 , a pair of second insulating assemblies 30 , an upper cover 40 , a lower cover 50 , and a pair of mounting members 60 .
[0031] Continue to refer Figure 1 to Figure 2 , the first insulating assembly 20 is arranged between the paired conductors 10. The paired second insulating assemblies 30 are each arranged on a side of the paired conductors 10 away from the first insulating assembly 20. It can be understood that along the first direction X, the upper cover 40, one second insulating assembly 30 of the paired second insulating assemblies 30, one conductor 10 of the paired conductors 10, the first insulating assembly 20, the other conductor 10 of the paired conductors 10, the other second insulating assembly 30 of the paired second insulating assembly 30, and the lower cover 50 are arranged in sequence. The bolts can pass through the bolt washers, the upper cover 40, the paired conductors 10, the first insulating assembly 20, the paired second insulating assemblies 30, the lower cover 50, the nut washers, and the bolts can be locked by nuts.
[0032] Figure 3 FIG. 1 is a schematic diagram showing the structure of a conductor 10 according to some embodiments of the present disclosure. Figure 3 As shown, the paired conductors 10 are each integrally formed. Therefore, the conductor 10 according to the embodiment of the present disclosure can eliminate the design of the middle insulating member, so that the conductor 10 can conduct the busbars on both sides without changing the size of the conductor 10; at the same time, since the conductor 10 eliminates the design of the middle insulating member, the thermal conductivity of the electrical connector 100 is improved, thereby significantly reducing the temperature rise at the electrical connector 100.
[0033] By utilizing the above configuration, when one busbar of the same-pole busbar is in contact with one side of the conductor 10 and the other busbar of the same-pole busbar is in contact with the other side of the conductor 10, since the conductor 10 can conduct the busbars on both sides thereof, the busbars of the same pole can be connected in parallel again at the position of the electrical connector 100 through the conductor 10, that is, the electrical connector 100 can achieve a convergence effect, thereby solving the problem of load or current imbalance of the busbars of the same pole downstream of the loop.
[0034] Continue reading Figures 1 to 3 , further, the paired conductors 10 may each include a mounting hole 12. The paired mounting members 60 may each be disposed in the mounting hole 12 of the corresponding conductor 10. Along the first direction X, one end of each mounting member 60 in the paired mounting members 60 may be matched with the corresponding first insulating assembly 20, and the other opposite end of each mounting member 60 in the paired mounting members 60 may be matched with the corresponding second insulating assembly 30.
[0035] Continue reading Figures 1 to 3Further, the paired conductors 10 may each include a guiding slope 13. The guiding slope 13 may extend along the second direction Y, and the second direction Y may be perpendicular to the first direction X. The guiding slope 13 may be located at the edge of the conductor 10. It can be understood that the guiding slope 13 can play a guiding role, thereby facilitating the insertion of the busbar.
[0036] Figures 4 to 7 Schematic diagrams of the structures of the conductor 10 according to other embodiments of the present disclosure are shown. Figures 4 to 7 The conductor 10 shown is Figure 3 The conductor 10 shown has similar structures, such as the mounting hole 12 and the guide slope 13, but is not limited thereto. The main difference is that Figures 4 to 7 The conductor 10 shown may include at least a pair of conductive members 1. In the following, the difference between the two will be mainly described, and the same parts will not be repeated.
[0037] refer to Figures 4 to 7 In some embodiments, the paired conductors 10 each include at least a paired conductive member 1. Therefore, the conductor 10 according to the embodiment of the present disclosure can eliminate the design of the middle insulating member, so that the conductor 10 can conduct the busbars on both sides without changing the size of the conductor 10; at the same time, since the conductor 10 eliminates the design of the middle insulating member, the thermal conductivity of the electrical connector 100 is improved, thereby significantly reducing the temperature rise at the electrical connector 100.
[0038] Using the above configuration, the conductor 10 includes at least a pair of conductive parts 1. When one busbar in the same-pole busbar is in contact with one side of the conductor 10, and the other busbar in the same-pole busbar is in contact with the other side of the conductor 10, since the conductor 10 can conduct the busbars on both sides, the busbars in the same pole can be connected in parallel again at the position of the electrical connector 100 through the conductor 10, that is, the electrical connector 100 can achieve a convergence effect, thereby solving the problem of load or current imbalance of the busbars in the same pole downstream of the loop.
[0039] Continue to refer Figures 4 to 7 Further, at least pairs of conductive members 1 may be arranged along the first direction X, and at least adjacent conductive members 1 in the pairs of conductive members 1 are connected.
[0040] It should be noted that the numbers, values, and quantities mentioned above and elsewhere in the present disclosure are exemplary and are not intended to limit the scope of the present disclosure in any way. Any other appropriate numbers, values, and quantities are possible.
[0041] For example, continue to refer to Figures 4 to 7 In some embodiments, the paired conductors 10 may each include a paired conductive member 1. The paired conductive members 1 may be arranged along the first direction X, and the paired conductive members 1 may be detachably connected.
[0042] In the following, the structure of the conductor 10 of the embodiment of the present disclosure will be mainly described by the pair of conductors 10 each including a pair of conductive parts 1, and the pair of conductive parts 1 are detachably connected. The case where the pair of conductors 10 each includes three or more conductive parts 1 is similar and will not be repeated here.
[0043] By utilizing the above configuration, when one busbar in the same-pole busbar is in contact with one of the conductive parts 1 and the other busbar in the same-pole busbar is in contact with the other conductive part 1, since the paired conductive parts 1 are connected, the same-pole busbars can be connected in parallel again at the position of the electrical connector 100 through the conductor 10, that is, the electrical connector 100 can achieve a convergence effect, thereby solving the problem of load or current imbalance of the same-pole busbars downstream of the loop.
[0044] refer to Figures 4 to 5 In some embodiments, the surfaces of the paired conductive members 1 adjacent to each other may be planes. Thus, the paired conductive members 1 are easy to install and are conducive to reducing production costs.
[0045] refer to Figure 6 to Figure 7 In some embodiments, each of the paired conductive members 1 includes a groove 11. The groove 11 can be provided on the surfaces of the paired conductive members 1 adjacent to each other. Of course, if the surfaces of the paired conductive members 1 adjacent to each other can be planes, then the groove 11 can be provided on the plane. It can be understood that the provision of the groove 11 is conducive to reducing the material used for the conductive member 1, thereby reducing the production cost of the conductor 10.
[0046] refer to Figure 7 , further, the grooves 11 of each conductive member 1 in the pair of conductive members 1 may be spaced apart from each other.
[0047] Continue to refer Figure 7 Furthermore, the groove 11 of each conductive member 1 in the pair of conductive members 1 may extend along a second direction Y perpendicular to the first direction X.
[0048] Continue to refer Figure 6 to Figure 7 Furthermore, the grooves 11 in the pair of conductive members 1 can be aligned with each other. Of course, the grooves 11 in the pair of conductive members 1 can also be staggered with each other.
[0049] Return to reference Figures 4 to 7 In some embodiments, when the paired conductors 10 may each include a mounting hole 12, one of the paired conductive members 1 may include a portion of the mounting hole 12, and the other conductive member 1 may include another portion of the mounting hole 12. It can be understood that when the paired conductive members 1 are connected to form the conductor 10, the mounting hole 12 of the conductor 10 is formed.
[0050] Return to reference Figures 4 to 7 In some embodiments, when the paired conductors 10 may each include a guide ramp 13, the guide ramp 13 may be provided on the paired conductive members 1, and the guide ramp 13 may be located at an edge of the conductive member 1 to facilitate insertion of the busbar.
[0051] Figure 8 A partial structural schematic diagram of a DC bus duct according to some embodiments of the present disclosure is shown. Fig. 9 Shows Figure 8 The front view of the DC bus duct is shown in Figure 2. Figures 8 to 9 As shown, an embodiment of the present disclosure further provides a DC bus duct, which includes any one of the electrical connectors 100 described above, and a base segment 200. The electrical connector 100 is located between adjacent base segments 200.
[0052] Continue to refer Figure 8 and Fig. 9 The base section 200 may include a first-phase busbar 201, a second-phase busbar 202, a third-phase busbar 203, a neutral busbar 204, and a pair of grounding busbars 205. One of the pair of grounding busbars 205 is located between the upper cover 40 and the corresponding second insulating assembly 30, and the other grounding busbar 205 is located between the lower cover 50 and the corresponding second insulating assembly 30. The first-phase busbar 201 is located between the upper second insulating assembly 30 and the upper conductor 10. The neutral busbar 204 is located between the lower second insulating assembly 30 and the lower conductor 10. The second-phase busbar 202 is located between the first insulating assembly 20 and the upper conductor 10. The third-phase busbar 203 is located between the first insulating assembly 20 and the lower conductor 10.
[0053] It can be seen that the first-phase busbar 201 and the second-phase busbar 202 can be connected in parallel via corresponding conductors 10 , and the third-phase busbar 203 and the neutral busbar 204 can be connected in parallel via corresponding conductors 10 .
[0054] It should be noted that the return reference Figure 2 In some embodiments, the first insulating assembly 20 may include a first insulating plate 21 and a pair of first conductive plates 22. One of the pair of first conductive plates 22 is disposed on one side of the first insulating plate 21, and the other first conductive plate 22 is disposed on the other side of the first insulating plate 21 along the first direction X. The first insulating plate 21 is sandwiched between the pair of first conductive plates 22 and can prevent the pair of first conductive plates 22 from conducting.
[0055] Understandably, reference Figure 2 and Fig. 9The first insulating assembly 20 can prevent the second-phase busbar 202 and the third-phase busbar 203 from being conductive through the first insulating plate 21 to achieve an insulating effect. However, due to the presence of the paired first conductive plates 22, the same busbars of adjacent base segments 200 can be conductive (for example, the second-phase busbars 202 of adjacent base segments 200 are conductive).
[0056] Return to reference Figure 2 In some embodiments, the paired second insulating components 30 may each include a second insulating plate 31 and a paired second conductive plate 32. One of the paired second conductive plates 32 is disposed on one side of the second insulating plate 31, and the other second conductive plate 32 is disposed on the other side opposite to the second insulating plate 31 along the first direction X. The second insulating plate 31 is sandwiched between the paired second conductive plates 32 and can prevent the paired second conductive plates 32 from conducting.
[0057] Similarly, refer to Figure 2 and Fig. 9 The second insulating assembly 30 can prevent the grounding busbar 205 from being connected to the first phase busbar 201 through the second insulating plate 31, and can also prevent the grounding busbar 205 from being connected to the fourth phase busbar 204 to achieve an insulation effect. However, due to the presence of the paired second conductive plates 32, the same busbars of adjacent base segments 200 can be connected (for example, the grounding busbars 205 of adjacent base segments 200 are connected).
[0058] The electrical connector 100 according to the embodiment of the present disclosure can be applied to various DC bus slots to at least partially solve the above problems. It should be understood that the electrical connector 100 according to the embodiment of the present disclosure can also be applied to other electrical components, and the embodiment of the present disclosure is not limited to this.
[0059] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
