Abstract
Description
Technical Field
[0001] This application relates to the field of switch technology, specifically to a reversible contactor assembly. Background Technology
[0002] A reversible contactor typically consists of two contactors, which switch the power phase sequence via a control circuit to achieve forward and reverse rotation of the motor. Currently, it is common practice to connect the main circuit output terminals of the two contactors in series with wires of the same phase. In this case, the wires need to be cut according to the actual distance and shaped before connecting to the contactors. This not only makes the installation and operation more cumbersome, but also easily leads to damage or even breakage of the wires at bends.
[0003] Therefore, busbars are often used instead of wires. The terminals of busbars can be plugged into contactors, making operation more convenient.
[0004] Meanwhile, for safe electricity use, a relay is usually connected to the main circuit output terminal of one of the contactors.
[0005] However, in the existing technology, the connection between the relay and the contactor is inconvenient in actual operation, and there is a possibility that the reversible contactor assembly occupies a large amount of space. Utility Model Content
[0006] This application provides a reversible contactor assembly that facilitates the connection between a relay and a contactor, thereby reducing the space occupied by the reversible contactor assembly.
[0007] To achieve the above objectives, this application provides a reversible contactor assembly including a relay, a busbar, and two contactors arranged side-by-side along a first direction. The relay is electrically connected to the main circuit output terminal of one of the contactors. At least one of a latch and a slot that cooperates with each other is provided on the contactor electrically connected to the relay, and the relay is provided with the other of a latch and a slot. The busbar is electrically connected to the main circuit output terminals of the two contactors, for cross-connection of the phase sequence of the main circuit output terminals of the two contactors. A clearance hole is provided on the busbar, through which the latch passes and engages with the slot.
[0008] When adopting the above technical solution, in specific implementation, the conductive busbar can be connected to the contactor first, and the conductive busbar can be electrically connected to the main circuit output terminals of the two contactors.
[0009] Subsequently, when connecting the relay and contactor, the clip and slot can be aligned and matched. The clip is inserted into the slot, thereby engaging the relay and contactor. The operation is simple and convenient, and the arrangement of the conductor bar will not interfere with the relay.
[0010] Meanwhile, the orthographic projection of the conductor bar on the contactor overlaps with the orthographic projection of the relay on the contactor, which can reduce the space occupied by the conductor bar and the relay, and further reduce the space occupied by the reversible contactor assembly.
[0011] In one possible implementation, the conductive busbar includes a carrier plate, a first connecting busbar, a second connecting busbar, and a third connecting busbar, with clearance holes formed on the carrier plate. The first connecting busbar includes a first terminal, a first connecting portion, and a second terminal connected sequentially along a first direction. The first connecting portion is disposed on the carrier plate and has a first opening space. The second connecting busbar includes a third terminal, a second connecting portion, and a fourth terminal connected sequentially along the first direction. The second connecting portion is disposed on the carrier plate and located within the first opening space, having a second opening space. The third connecting busbar includes a fifth terminal, a third connecting portion, and a sixth terminal connected sequentially along the first direction. The third connecting portion is disposed on the carrier plate and located within the second opening space.
[0012] When the above technical solution is adopted, the first connecting part has a first opening space, the second connecting part is located within the first opening space, the second connecting part has a second opening space, and the third connecting part is located within the second opening space. Thus, the first terminal block, the third terminal block, the fifth terminal block, the sixth terminal block, the fourth terminal block, and the second terminal block are sequentially arranged along the first direction. At this time, when the conductor bar is connected to the two contactors, the function of cross-connection of the phase sequence of the main circuit output terminals of the two contactors can be realized.
[0013] In one possible implementation, the first connecting part is integrally injection molded with the support plate.
[0014] When the above technical solution is adopted, no subsequent assembly process is required, which shortens the production cycle to a certain extent and improves the production efficiency of the conductive busbar. On the other hand, it can reduce dimensional errors caused by assembly. At the same time, the first connecting part and the supporting plate are integrally injection molded, which can enhance the overall structural integrity of the conductive busbar and improve its structural strength.
[0015] In one possible implementation, the second connecting part is integrally injection molded with the support plate.
[0016] When the above technical solution is adopted, no subsequent assembly process is required, which shortens the production cycle to a certain extent and improves the production efficiency of the conductive busbar. On the other hand, it can reduce dimensional errors caused by assembly. At the same time, the second connecting part is integrally injection molded with the supporting plate, which can enhance the overall structural integrity of the conductive busbar and improve its structural strength.
[0017] In one possible implementation, the third connecting part is integrally injection molded with the support plate.
[0018] When the above technical solution is adopted, no subsequent assembly process is required, which shortens the production cycle to a certain extent and improves the production efficiency of the conductive busbar. On the other hand, it can reduce dimensional errors caused by assembly. At the same time, the third connecting part is integrally injection molded with the supporting plate, which can enhance the overall structural integrity of the conductive busbar and improve its structural strength.
[0019] In one possible implementation, a first notch is provided on the carrier plate at the position corresponding to the first terminal and the third terminal.
[0020] In one possible implementation, a second notch is provided on the carrier plate at the position corresponding to the third terminal and the fifth terminal.
[0021] In one possible implementation, a third notch is provided on the carrier plate at the position corresponding to the fifth terminal and the sixth terminal.
[0022] In one possible implementation, a fourth notch is provided on the carrier plate at the position corresponding to the sixth terminal and the fourth terminal.
[0023] In one possible implementation, a fifth notch is provided on the carrier plate at the position corresponding to the fourth terminal and the second terminal.
[0024] When the above technical solution is adopted, the setting of the first notch, the second notch, the third notch, the fourth notch and the fifth notch can reduce the weight of the support plate, and at the same time, can reduce the amount of material used in the support plate.
[0025] In one possible implementation, an arc-blocking plate is provided on the relay at the positions corresponding to the first, second, fourth, and fifth notches, and the arc-blocking plate is perpendicular to the support plate. The contactor is provided with a slot that mates with the arc-blocking plate.
[0026] When the above technical solution is adopted, the arc-shielding plate can enhance the interphase insulation of the reversible contactor assembly provided in this application embodiment. Simultaneously, when the relay is installed on the contactor, the arc-shielding plate, in conjunction with the slot, can improve the secure mounting of the relay on the contactor.
[0027] In one possible implementation, the first terminal block, the second terminal block, the third terminal block, the fourth terminal block, the fifth terminal block, and the sixth terminal block all extend along a second direction, which is perpendicular to the support plate. In this second direction, the cross-section of the first terminal block is uniform.
[0028] When the above technical solution is adopted, not only can the electrical connection area between the first terminal and the contactor be ensured, and the connection stability be ensured, but also the heat dissipation effect of the first terminal can be guaranteed.
[0029] In one possible implementation, the cross-section of the second terminal is consistent in the second direction.
[0030] When the above technical solution is adopted, not only can the electrical connection area between the second terminal and the contactor be ensured, and the connection stability be ensured, but also the heat dissipation effect of the second terminal can be guaranteed.
[0031] In one possible implementation, the cross-section of the third terminal is consistent in the second direction.
[0032] When the above technical solution is adopted, not only can the electrical connection area between the third terminal and the contactor be ensured, thus ensuring connection stability, but also the heat dissipation effect of the third terminal can be guaranteed.
[0033] In one possible implementation, the cross-section of the fourth terminal is consistent in the second direction.
[0034] When the above technical solution is adopted, not only can the electrical connection area between the fourth terminal and the contactor be ensured, thus ensuring connection stability, but also the heat dissipation effect of the fourth terminal can be guaranteed.
[0035] In one possible implementation, the cross-section of the fifth terminal is consistent in the second direction.
[0036] When the above technical solution is adopted, not only can the electrical connection area between the fifth terminal and the contactor be ensured, thus ensuring connection stability, but also the heat dissipation effect of the fifth terminal can be guaranteed.
[0037] In one possible implementation, the cross-section of the sixth terminal is consistent in the second direction.
[0038] When the above technical solution is adopted, not only can the electrical connection area between the sixth terminal and the contactor be ensured, and the connection stability be ensured, but also the heat dissipation effect of the sixth terminal can be guaranteed.
[0039] In one possible implementation, the third connecting portion has a third opening space, and the opening directions of the first opening space, the second opening space, and the third opening space are the same.
[0040] When using the above technical solution, in actual connection, the first, second, third, fourth, fifth, and sixth terminals are all located below the main circuit output terminals of the corresponding contactors. The conductor busbars have a neat and aesthetically pleasing appearance.
[0041] In one possible implementation, the first connecting part is located on the first plane, the second connecting part is located on the second plane, and the third connecting part is located on the third plane, with the first, second, and third planes all parallel to the support plate.
[0042] When the above technical solution is adopted, the first connecting part, the second connecting part and the third connecting part can be staggered, which helps to increase the distance between the first connecting part, the second connecting part and the third connecting part, effectively reducing the possibility of heat source concentration, facilitating the heat dissipation of the conductive busbar, and improving the heat dissipation effect of the conductive busbar.
[0043] In one possible implementation, the side of the carrier plate near the contactor has one of a protrusion and a recess that cooperate with each other, and the contactor has the other of a protrusion and a recess.
[0044] When the above technical solution is adopted, the protrusion and the recess cooperate to improve the stability of the connection between the conductor bus and the contactor when the conductor bus is installed on the contactor.
[0045] In addition, during the installation of the busbar on the contactor, aligning the protrusions with the recesses facilitates quick installation. This also effectively reduces the possibility of the busbar being installed backwards.
[0046] In one possible implementation, wiring markings are provided on the side of the carrier plate away from the first connection bar.
[0047] When the above technical solution is adopted, the arrangement of the first connecting bar, the second connecting bar and the third connecting bar in the carrier plate can be shown more intuitively, making it easier for users to identify the purpose of the conductive bar.

[0066] In existing technologies, when connecting relays and busbars to contactors, the busbars generally interfere with the relays, making the connection inconvenient. Furthermore, after connecting the relays and busbars to the contactor, the projections of the busbars onto the contactor and the relays onto the contactor often do not overlap, potentially leading to a large space requirement for the reversible contactor assembly.
[0067] In view of the problems existing in the prior art, such as Figure 1 As shown in the figure, this application embodiment provides a reversible contactor assembly, which includes a relay 2, a conductor bar 3, and two contactors arranged side by side along a first direction. The relay 2 is electrically connected to the main circuit output terminal of one of the contactors.
[0068] For ease of description, the two contactors are hereby defined as the first contactor 11 and the second contactor 12, as follows: Figure 1 and Figure 2 As shown.
[0069] The first contactor 11 and the second contactor 12 are arranged side by side along the first direction. The side wall of the first contactor 11 can be fitted together with the side wall of the second contactor 12. The first contactor 11 can be fixedly connected to the second contactor 12.
[0070] The fixed connection method between the first contactor 11 and the second contactor 12 is not limited here.
[0071] For example, the first contactor 11 and the second contactor 12 can be fixedly connected by means of adhesive bonding, snap-fitting, or welding. Of course, the actual method is not limited to this.
[0072] In the embodiments provided in this application, the first contactor 11 and the second contactor 12 may each have three main circuit output terminals. The specific models of the first contactor 11 and the second contactor 12 are not limited here, nor are their specific structures and dimensions.
[0073] In practice, each contactor has three main circuit output terminals T1, T2, and T3, and these three terminals are arranged sequentially along the first direction.
[0074] Relay 2 has three terminals at both ends, with one end of relay 2 corresponding to the main circuit output terminal of one of the contactors. Furthermore, the three terminals at one end of relay 2 correspond to the three main circuit output terminals T1, T2, and T3 on one of the contactors.
[0075] When wiring, the three terminals of the load can be connected to the three terminals on the other end of relay 2 respectively.
[0076] At least one of a latch 21 and a slot 13 that is electrically connected to the relay 2 is provided on the contactor, and the other of the latch 21 and slot 13 is provided on the relay 2. The latch 21 and slot 13 are provided to engage with the contactor.
[0077] In practical implementation, a latch 21 can be set on relay 2, and a slot 13 can be set on one of the contactors. Please refer to the following: Figures 1 to 3 As shown.
[0078] For example, a latch 21 can be provided on the relay 2, and a slot 13 can be provided on the first contactor 11 or the second contactor 12. Alternatively, a latch 21 can be provided on the relay 2, and slots 13 can be provided on both the first contactor 11 and the second contactor 12, so that the relay 2 can be connected to either the first contactor 11 or the second contactor 12 when needed.
[0079] The conductor bar 3 is electrically connected to the main circuit output terminals of the two contactors to enable the phase sequence of the main circuit output terminals of the two contactors to be cross-connected.
[0080] In practice, the conductor bus 3 is installed on the contactor to improve the stability of the electrical connection between the conductor bus 3 and the main circuit output terminals of the two contactors.
[0081] The method of installing the conductive busbar 3 on the contactor is not limited here; the specific method depends on the actual situation.
[0082] It should be noted that the main circuit output terminals of the two contactors are connected in a cross-phase sequence. Specifically, the main circuit output terminal T1 of the first contactor 11 is electrically connected to the main circuit output terminal T3 of the second contactor 12. At the same time, the main circuit output terminal T2 of the first contactor 11 is electrically connected to the main circuit output terminal T2 of the second contactor 12, and the main circuit output terminal T3 of the first contactor 11 is electrically connected to the main circuit output terminal T1 of the second contactor 12.
[0083] Please combine Figures 1 to 4 As shown, the conductive busbar 3 has a clearance hole 311, and the buckle 21 passes through the clearance hole 311 and engages with the slot 13.
[0084] Thus, in practical implementation, the conductive busbar 3 can be connected to the contactor first, and the conductive busbar 3 can be electrically connected to the main circuit output terminals of the two contactors.
[0085] Subsequently, when connecting relay 2 to the contactor, the latch 21 and the slot 13 can be aligned and matched. The latch 21 is inserted into the slot 13, thereby engaging relay 2 with the contactor. The operation is simple and convenient, and the arrangement of the conductive busbar 3 will not interfere with relay 2.
[0086] Meanwhile, the orthographic projection of the conductor bar 3 on the contactor overlaps with the orthographic projection of the relay 2 on the contactor, which can reduce the space occupied by the conductor bar 3 and the relay 2, and further reduce the space occupied by the reversible contactor assembly.
[0087] In one possible implementation, the conductive busbar 3 includes a carrier plate 31, a first connecting busbar 32, a second connecting busbar 33 and a third connecting busbar 34, and the carrier plate 31 is provided with a clearance hole 311.
[0088] The specific structure and dimensions of the bearing plate 31 are not specified here, and shall be subject to the actual situation.
[0089] In the embodiments provided in this application, the support plate 31 can be a rectangular structure. Of course, it is not limited to this.
[0090] It should be noted that the support plate 31 can be made of an insulating material. For example, the support plate 31 can be made of plastic.
[0091] In practice, the first connecting bar 32, the second connecting bar 33, and the third connecting bar 34 can be located on the side of the support plate 31 closer to the contactor, so that the first connecting bar 32, the second connecting bar 33, and the third connecting bar 34 can be electrically connected to the main circuit output terminals of the two contactors.
[0092] The arrangement of the first connecting row 32, the second connecting row 33, and the third connecting row 34 on the support plate 31 is not specifically limited here.
[0093] For example, the first connecting row 32, the second connecting row 33, and the third connecting row 34 can be installed on the support plate 31 by means of riveting, snap-fitting, or welding.
[0094] like Figure 5 As shown, the first connecting bar 32 includes a first terminal 321, a first connecting part 322 and a second terminal 323 connected sequentially along a first direction, that is, the two ends of the first connecting part 322 are respectively connected to the first terminal 321 and the second terminal 323.
[0095] The first connecting strip 32 can be a split structure, that is, the first terminal block 321, the first connecting part 322, and the second terminal block 323 are set separately. During installation, the first terminal block 321 and the second terminal block 323 are respectively connected to the two ends of the first connecting part 322.
[0096] The connection method between the first terminal 321 and the first connecting part 322 is not specifically limited here. For example, the first terminal 321 and one end of the first connecting part 322 can be connected by welding, snap-fitting or threaded connection.
[0097] The connection method between the second terminal 323 and the first connecting part 322 is not specifically limited here. For example, the second terminal 323 can be connected to the other end of the first connecting part 322 by means of welding, snap-fit, or threaded connection.
[0098] In the embodiments provided in this application, the first connecting strip 32 can be an integral structure. In specific implementation, the connecting strip with a circular or polygonal cross-section and a long strip shape can be bent to form the first terminal 321, the first connecting part 322, and the second terminal 323.
[0099] The material of the first connecting row 32 can be copper or aluminum, but it is not limited to these in practice.
[0100] like Figure 4 and Figure 5 As shown, the first terminal 321 and the second terminal 323 are arranged along the first direction, and the first connecting part 322 is disposed on the support plate 31.
[0101] In fact, the first terminal 321 corresponds to the main circuit output terminal T1 of the first contactor 11, and the second terminal 323 corresponds to the main circuit output terminal T3 of the second contactor 12.
[0102] In actual connection, the first terminal 321 can be inserted into the first contactor 11, so that the first terminal 321 is electrically connected to the main circuit output terminal T1 of the first contactor 11. The second terminal 323 is inserted into the second contactor 12, so that the second terminal 323 is electrically connected to the main circuit output terminal T3 of the second contactor 12.
[0103] The first connecting part 322 is disposed on the support plate 31, thereby disposing the first connecting row 32 on the support plate 31. The manner in which the first connecting part 322 is disposed on the support plate 31 is not specifically limited here.
[0104] For example, the first connecting part 322 can be installed on the support plate 31 by means of riveting, snap-fitting or welding.
[0105] like Figure 5 As shown, the second connecting bar 33 includes a third terminal 331, a second connecting part 332 and a fourth terminal 333 connected sequentially along the first direction, that is, the two ends of the second connecting part 332 are respectively connected to the third terminal 331 and the fourth terminal 333.
[0106] The second connecting strip 33 can be a split structure, that is, the third terminal 331, the second connecting part 332, and the fourth terminal 333 are separately arranged. During installation, the third terminal 331 and the fourth terminal 333 are respectively connected to the two ends of the second connecting part 332.
[0107] The connection method between the third terminal 331 and the second connecting part 332 is not specifically limited here. For example, the third terminal 331 can be connected to one end of the second connecting part 332 by means of welding, snap-fit, or threaded connection.
[0108] The connection method between the fourth terminal 333 and the second connecting part 332 is not specifically limited here. For example, the fourth terminal 333 can be connected to the other end of the second connecting part 332 by means of welding, snap-fit, or threaded connection.
[0109] In the embodiments provided in this application, the second connecting strip 33 can be an integral structure. In specific implementation, the connecting strip with a circular or polygonal cross-section and a long strip shape can be bent to form the third terminal 331, the second connecting part 332, and the fourth terminal 333.
[0110] The material of the second connecting row 33 can be copper or aluminum, but it is not limited to these in practice.
[0111] In fact, the third terminal 331 corresponds to the main circuit output terminal T2 of the first contactor 11, and the fourth terminal 333 corresponds to the main circuit output terminal T2 of the second contactor 12.
[0112] In actual connection, the third terminal 331 can be inserted into the first contactor 11, and the third terminal 331 can be electrically connected to the main circuit output terminal T2 of the first contactor 11. The fourth terminal 333 can be inserted into the second contactor 12, and the fourth terminal 333 can be electrically connected to the main circuit output terminal T2 of the second contactor 12.
[0113] like Figure 4 and Figure 5 As shown, the third terminal block 331 and the fourth terminal block 333 are arranged along the first direction, and the second connecting part 332 is disposed on the support plate 31, thereby placing the second connecting block 33 on the support plate 31. The manner in which the second connecting part 332 is disposed on the support plate 31 is not specifically limited here.
[0114] For example, the second connecting part 332 can be installed on the support plate 31 by means of riveting, snap-fitting or welding.
[0115] Please continue to refer to this. Figure 5 As shown, the third connection bar 34 includes a fifth terminal 341, a third connection part 342 and a sixth terminal 343 connected sequentially along the first direction, that is, the two ends of the third connection part 342 are connected to the fifth terminal 341 and the sixth terminal 343 respectively.
[0116] The third connecting strip 34 can be a split structure, that is, the fifth terminal 341, the third connecting part 342, and the sixth terminal 343 are set separately. During installation, the fifth terminal 341 and the sixth terminal 343 are respectively connected to the two ends of the third connecting part 342.
[0117] The connection method between the fifth terminal 341 and the third connecting part 342 is not specifically limited here. For example, the fifth terminal 341 and one end of the third connecting part 342 can be connected by welding, snap-fitting, or threaded connection.
[0118] The connection method between the sixth terminal 343 and the third connecting part 342 is not specifically limited here. For example, the sixth terminal 343 can be connected to the other end of the third connecting part 342 by means of welding, snap-fit, or threaded connection.
[0119] In the embodiments provided in this application, the third connecting strip 34 can be an integral structure. In specific implementation, the connecting strip with a circular or polygonal cross-section and a long strip shape can be bent to form the fifth terminal 341, the third connecting part 342, and the sixth terminal 343.
[0120] The material of the third connecting row 34 can be copper or aluminum, but it is not limited to these in practice.
[0121] In fact, the fifth terminal 341 corresponds to the main circuit output terminal T3 of the first contactor 11, and the sixth terminal 343 corresponds to the main circuit output terminal T1 of the second contactor 12.
[0122] In actual connection, the fifth terminal 341 can be inserted into the first contactor 11, and the fifth terminal 341 can be electrically connected to the main circuit output terminal T3 of the first contactor 11. The sixth terminal 343 can be inserted into the second contactor 12, and the sixth terminal 343 can be electrically connected to the main circuit output terminal T1 of the second contactor 12.
[0123] like Figure 4 and Figure 5 As shown, the fifth terminal 341 and the sixth terminal 343 are arranged along the first direction, and the third connecting part 342 is disposed on the support plate 31, thereby disposing the third connecting row 34 on the support plate 31. The manner in which the third connecting part 342 is disposed on the support plate 31 is not specifically limited here.
[0124] For example, the third connecting part 342 can be installed on the bearing plate 31 by means of riveting, snap-fitting or welding.
[0125] like Figure 5 As shown, the first connecting portion 322 has a first opening space, the second connecting portion 332 is located within the first opening space, the second connecting portion 332 has a second opening space, and the third connecting portion 342 is located within the second opening space. Thus, the first terminal block 321, the third terminal block 331, the fifth terminal block 341, the sixth terminal block 343, the fourth terminal block 333, and the second terminal block 323 are arranged sequentially along the first direction.
[0126] Please combine Figure 2 and Figure 4As shown, when the conductive busbar 3 is connected to the first contactor 11 and the second contactor 12, the first terminal 321 is electrically connected to the main circuit output terminal T1 of the first contactor 11, and the second terminal 323 is electrically connected to the main circuit output terminal T3 of the second contactor 12. The third terminal 331 is electrically connected to the main circuit output terminal T2 of the first contactor 11, and the fourth terminal 333 is electrically connected to the main circuit output terminal T2 of the second contactor 12. The fifth terminal 341 is electrically connected to the main circuit output terminal T3 of the first contactor 11, and the sixth terminal 343 is electrically connected to the main circuit output terminal T1 of the second contactor 12.
[0127] Thus, by using the conductive busbar 3 provided in the embodiments of this application, the main circuit output terminals of the first contactor 11 and the second contactor 12 can be cross-connected in phase sequence.
[0128] In practical operation, by connecting the main circuit input terminals of the first contactor 11 and the second contactor 12 in series in the same phase, the forward and reverse rotation of the motor can be achieved.
[0129] In one example, the first connecting part 322 is integrally injection molded with the support plate 31.
[0130] Thus, no subsequent assembly process is required, which shortens the production cycle to a certain extent and improves the production efficiency of the conductive busbar 3. On the other hand, it can reduce dimensional errors caused by assembly. At the same time, the first connecting part 322 and the supporting plate 31 are integrally injection molded, which can enhance the structural integrity of the conductive busbar 3 and improve its structural strength.
[0131] Furthermore, the second connecting part 332 and the supporting plate 31 are integrally injection molded.
[0132] Thus, no subsequent assembly process is required, which shortens the production cycle to a certain extent and improves the production efficiency of the conductive busbar 3. On the other hand, it can reduce dimensional errors caused by assembly. At the same time, the second connecting part 332 and the supporting plate 31 are integrally injection molded, which can enhance the structural integrity of the conductive busbar 3 and improve its structural strength.
[0133] Furthermore, the third connecting part 342 is integrally injection molded with the support plate 31.
[0134] Thus, no subsequent assembly process is required, which shortens the production cycle to a certain extent and improves the production efficiency of the conductive busbar 3. On the other hand, it can reduce dimensional errors caused by assembly. At the same time, the third connecting part 342 and the supporting plate 31 are integrally injection molded, which can enhance the structural integrity of the conductive busbar 3 and improve its structural strength.
[0135] In actual processing, the first connecting row 32, the second connecting row 33 and the third connecting row 34 can be cut and pressed into shape first, and then the first connecting row 32, the second connecting row 33 and the third connecting row 34 can be injection molded together with the support plate 31.
[0136] In some embodiments, such as Figure 4 As shown, a first recess 312 is provided on the support plate 31 at the position between the first terminal 321 and the third terminal 331. A second recess 313 is provided on the support plate 31 at the position between the third terminal 331 and the fifth terminal 341. A third recess 314 is provided on the support plate 31 at the position between the fifth terminal 341 and the sixth terminal 343. A fourth recess 315 is provided on the support plate 31 at the position between the sixth terminal 343 and the fourth terminal 333. A fifth recess 316 is provided on the support plate 31 at the position between the fourth terminal 333 and the second terminal 323.
[0137] In this case, the arrangement of the first notch 312, the second notch 313, the third notch 314, the fourth notch 315 and the fifth notch 316 can reduce the weight of the support plate 31 and at the same time reduce the amount of material used in the support plate 31.
[0138] As a formable mode, please combine Figures 1 to 4 As shown, at the positions corresponding to the first recess 312, the second recess 313, the fourth recess 315, and the fifth recess 316, the relay 2 is provided with an arc-blocking plate 22, which is perpendicular to the support plate 31. The contactor is provided with a slot 14 that mates with the arc-blocking plate 22.
[0139] Thus, the arc-shielding plate 22 enhances the interphase insulation of the reversible contactor assembly provided in this embodiment. Simultaneously, when the relay 2 is mounted on the contactor, the arc-shielding plate 22 engages with the slot 14, improving the secure mounting of the relay 2 on the contactor.
[0140] In one possible implementation, the first terminal 321, the second terminal 323, the third terminal 331, the fourth terminal 333, the fifth terminal 341, and the sixth terminal 343 all extend along a second direction, which is perpendicular to the support plate 31. In this second direction, the cross-section of the first terminal 321 is uniform.
[0141] At this time, not only can the electrical connection area between the first terminal 321 and the contactor be ensured, thus ensuring connection stability, but also the heat dissipation effect of the first terminal 321 can be guaranteed.
[0142] In one example, the cross-section of the second terminal 323 is consistent in the second direction.
[0143] At this time, not only can the electrical connection area between the second terminal 323 and the contactor be ensured, thus ensuring connection stability, but also the heat dissipation effect of the second terminal 323 can be guaranteed.
[0144] In another example, the cross-section of the third terminal 331 is consistent in the second direction.
[0145] Similarly, this not only ensures the electrical connection area between the third terminal 331 and the contactor, thus ensuring connection stability, but also guarantees the heat dissipation effect of the third terminal 331.
[0146] Furthermore, in the second direction, the cross-section of the fourth terminal 333 is consistent.
[0147] This not only ensures the electrical connection area between the fourth terminal 333 and the contactor, thus ensuring connection stability, but also guarantees the heat dissipation effect of the fourth terminal 333.
[0148] Furthermore, in the second direction, the cross-section of the fifth terminal 341 is consistent.
[0149] This not only ensures the electrical connection area between the fifth terminal 341 and the contactor, thus ensuring connection stability, but also guarantees the heat dissipation effect of the fifth terminal 341.
[0150] Furthermore, in the second direction, the cross-section of the sixth terminal 343 is consistent.
[0151] This not only ensures the electrical connection area between the sixth terminal 343 and the contactor, thus ensuring connection stability, but also guarantees the heat dissipation effect of the sixth terminal 343.
[0152] In one possible implementation, such as Figure 5 As shown, the third connecting part has a third opening space, and the opening directions of the first opening space, the second opening space, and the third opening space are the same.
[0153] Thus, in actual connection, the first terminal 321, the second terminal 323, the third terminal 331, the fourth terminal 333, the fifth terminal 341, and the sixth terminal 343 are all located below the main circuit output terminals of the corresponding contactors. The conductive busbar 3 has a neat and aesthetically pleasing appearance.
[0154] In one alternative embodiment, the first connecting portion 322 is located on a first plane, the second connecting portion 332 is located on a second plane, and the third connecting portion 342 is located on a third plane, with the first, second, and third planes all parallel to the support plate 31.
[0155] The first connecting part 322, the second connecting part 332 and the third connecting part 342 can be staggered, which helps to increase the distance between the first connecting part 322, the second connecting part 332 and the third connecting part 342, effectively reducing the possibility of heat source concentration, which is conducive to heat dissipation of the conductive busbar 3 and improves the heat dissipation effect of the conductive busbar 3.
[0156] In one possible implementation, the carrier plate 31 has one of a protrusion and a recess that cooperate with each other on the side near the contactor, and the contactor has the other of a protrusion and a recess.
[0157] At this time, when the conductive busbar 3 is installed on the contactor, the protrusion and the recess cooperate to improve the stability of the connection between the conductive busbar 3 and the contactor.
[0158] Furthermore, during the installation of the conductor busbar 3 onto the contactor, aligning the protrusions with the recesses facilitates quick installation of the conductor busbar 3. Simultaneously, it effectively reduces the possibility of the conductor busbar 3 being installed backwards.
[0159] In practice, a protrusion can be provided on the support plate 31, and a corresponding recess can be provided on the contactor. Alternatively, a recess can be provided on the support plate 31, and a protrusion can be provided on the contactor.
[0160] The location of the protrusions and recesses is not specifically limited here, and shall be determined according to the actual situation. Similarly, the number of protrusions and recesses is not specifically limited here.
[0161] In some embodiments, such as Figure 2 and Figure 4 As shown, a wiring mark 317 is provided on the side of the support plate 31 away from the first connection row 32.
[0162] At this point, the arrangement of the first connecting row 32, the second connecting row 33 and the third connecting row 34 within the carrier plate 31 can be shown more intuitively, making it easier for users to identify the purpose of the conductive row 3.
[0163] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, "connection" or "joining" in mechanical structures can refer to a physical connection, such as a fixed connection, for example, a connection fixed by fasteners, such as a connection fixed by screws, bolts, or other spacers; a physical connection can also be a detachable connection, such as a snap-fit or interlocking connection; a physical connection can also be an integral connection, such as a connection formed by welding, bonding, or integral molding. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
