Abstract
Description
Technical Field
[0001] This application relates to the field of switch technology, specifically to a conductive busbar and a reversible contactor. 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 input 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, conductive busbars are often used instead of wires. The terminals of conductive busbars can be plugged into contactors, making operation more convenient.
[0004] However, existing conductive busbars suffer from poor heat dissipation. Therefore, there is an urgent need to propose a conductive busbar to solve the problems existing in the current technology. Utility Model Content
[0005] This application provides a conductive bus and a reversible contactor for improving the heat dissipation effect of the conductive bus.
[0006] To achieve the above objectives, in a first aspect, this application provides a conductive bus, which includes a carrier plate and a first connecting bus, a second connecting bus and a third connecting bus disposed on the same side of the carrier plate.
[0007] The first connecting bar includes a first terminal block, a first connecting part, and a second terminal block connected sequentially along a first direction. The first connecting part is disposed on a support plate. The first connecting part is located in a first plane, and both the first plane and the first direction are parallel to the support plate.
[0008] The second connecting bar includes a third terminal block, a second connecting part, and a fourth terminal block connected sequentially along a first direction. The second connecting part is disposed on a support plate. The second connecting part is located in a second plane, which is parallel to the support plate.
[0009] The third connection bar includes a fifth terminal block, a third connection part, and a sixth terminal block connected sequentially along a first direction. The third connection part is disposed on a support plate. At least a portion of the third connection part is located in a third plane, which is parallel to the support plate.
[0010] The first terminal block, the third terminal block, the fifth terminal block, the second terminal block, the fourth terminal block, and the sixth terminal block are arranged sequentially along the first direction.
[0011] When the above technical solution is adopted, the first connecting part is located in the first plane, the second connecting part is located in the second plane, at least part of the third connecting part is located in the third plane, and the first plane, the second plane, and the third plane are parallel.
[0012] In other words, the first connecting part and the second connecting part are not in the same plane, the first connecting part and at least part of the third connecting part are not in the same plane, and the second connecting part and at least part of the third connecting part are not in the same plane.
[0013] Compared to the prior art where the first, second, and third connecting parts are all in the same plane, the conductive bus provided in this application can stagger the first, second, and third connecting parts, which helps to increase the distance between the first, second, and third connecting parts, effectively reducing the possibility of heat source concentration, facilitating heat dissipation of the conductive bus, and improving the heat dissipation effect of the conductive bus.
[0014] In one possible implementation, the third connecting part includes a first connecting segment and a second connecting segment, wherein the first connecting segment is located in a third plane and the second connecting segment is located in a first plane.
[0015] When the above technical solution is adopted, the first connecting part and the second connecting segment are both located in the first plane, the second connecting part is located in the second plane, and the first connecting segment is located in the third plane.
[0016] In one possible implementation, the second plane coincides with the third plane.
[0017] When the above technical solution is adopted, both the first connecting part and the second connecting segment are located in the first plane, and the second connecting part and the first connecting segment are located in the same plane.
[0018] This makes it easier to reduce the space occupied by the first connecting part, the second connecting part, and the third connecting part in the second direction, thereby improving the compactness of the busbar.
[0019] In one possible implementation, the third connecting part includes a first connecting segment and a second connecting segment, the first connecting segment being located in a second plane and the second connecting segment being located in a third plane.
[0020] When the above technical solution is adopted, the first connecting part is located in the first plane, the second connecting part and the first connecting segment are both located in the second plane, and the second connecting segment is located in the third plane.
[0021] The structure of the busbar has been enriched, making it easier to select and set it according to actual conditions.
[0022] In one possible implementation, the second connecting part is located in the second plane, the third connecting part is located in the third plane, and the first plane, the second plane, and the third plane are arranged sequentially along the second direction, which is perpendicular to the bearing plate.
[0023] In one possible implementation, the second connecting part is located in the second plane, the third connecting part is located in the third plane, and the first plane, the third plane, and the second plane are arranged sequentially along the second direction, which is perpendicular to the bearing plate.
[0024] The above technical solutions enrich the structural forms of the busbars, making it easier to select and set them according to actual conditions.
[0025] In one possible implementation, a busbar is used to connect the main circuit input terminals of two adjacent contactors in series in the same phase; the side of the carrier plate near the contactor is provided with one of a latch and a slot that cooperate with each other, and the contactor is provided with the other of a latch and a slot.
[0026] When the above technical solution is adopted, the slot and the buckle cooperate when the conductor busbar is installed on the contactor, which can improve the stability of the connection between the conductor busbar and the contactor.
[0027] Additionally, during the installation of the busbar onto the contactor, aligning the slots and clips facilitates quick installation and effectively reduces the possibility of incorrect installation.
[0028] In one possible implementation, the carrier plate is provided with through holes corresponding to 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.
[0029] When the above technical solution is adopted, the wiring terminals of the external power supply can pass through the through hole and be electrically connected to the corresponding main circuit input terminal of the contactor, which facilitates the electrical connection between the external power supply and the contactor.
[0030] In one possible implementation, wiring markings are provided on the side of the carrier plate away from the first connection bar.
[0031] 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.
[0032] Secondly, this application provides a reversible contactor, including two contactors and a conductive bus as described in any possible implementation of the first aspect, wherein the conductive bus is electrically connected to the main circuit input terminals of the two contactors for connecting the main circuit input terminals of the two contactors in series in the same phase.
[0033] The beneficial effects of the reversible contactor described in the second aspect can be referred to the beneficial effects of the conductive busbar described in the first aspect, and will not be repeated here. Attached Figure Description

[0049] like Figure 1 As shown in the figure, this application provides a reversible contactor, which includes two contactors and a conductive busbar 1. The conductive busbar 1 is electrically connected to the main circuit input terminals of the two contactors, and is used to connect the main circuit input terminals of the two contactors in series in the same phase.
[0050] For ease of description, the two contactors are hereby defined as the first contactor 21 and the second contactor 22, as follows: Figure 2 and Figure 3 As shown.
[0051] In the embodiments provided in this application, the first contactor 21 and the second contactor 22 may each have three main circuit input terminals. The specific models of the first contactor 21 and the second contactor 22 are not limited here, nor are their specific structures and dimensions.
[0052] In fact, each contactor has three main circuit input terminals L1, L2, and L3, and these three main circuit input terminals L1, L2, and L3 are arranged sequentially along the first direction.
[0053] In practice, the main circuit input terminals L1, L2, and L3 correspond to phases L1, L2, and L3 of the three-phase power supply, respectively. When wiring, phases L1, L2, and L3 of the three-phase power supply need to be connected to the main circuit input terminals L1, L2, and L3 of the first contactor 21 or the second contactor 22, respectively.
[0054] It should be noted that the contactor includes stationary contacts, and each contactor can include three stationary contacts. One end of the stationary contact is the main circuit input terminal, and the three stationary contacts correspond to the three main circuit input terminals L1, L2, and L3 respectively.
[0055] The first contactor 21 and the second contactor 22 are arranged side by side along the first direction. The side wall of the first contactor 21 can be fitted together with the side wall of the second contactor 22. The first contactor 21 can be fixedly connected to the second contactor 22.
[0056] The fixed connection method between the first contactor 21 and the second contactor 22 is not limited here.
[0057] For example, the first contactor 21 and the second contactor 22 can be fixedly connected by means of adhesive bonding, snap-fitting, or welding. Of course, the actual method is not limited to this.
[0058] It should be noted that the main circuit input terminals of the two contactors are connected in series with the same phase. That is, the main circuit input terminal L1 of the first contactor 21 is electrically connected to the main circuit input terminal L1 of the second contactor 22. At the same time, the main circuit input terminal L2 of the first contactor 21 is electrically connected to the main circuit input terminal L2 of the second contactor 22, and the main circuit input terminal L3 of the first contactor 21 is electrically connected to the main circuit input terminal L3 of the second contactor 22.
[0059] In one possible implementation, please combine Figure 2 and Figure 3 The conductive bus 1 provided in this application embodiment includes a carrier plate 11, and a first connecting bus 12, a second connecting bus 13 and a third connecting bus 14 disposed on the same side of the carrier plate 11.
[0060] The specific structure and dimensions of the bearing plate 11 are not specified here, but shall be subject to the actual situation.
[0061] In the embodiments provided in this application, the support plate 11 can be a rectangular structure. Of course, it is not limited to this.
[0062] It should be noted that the support plate 11 can be made of an insulating material. For example, the support plate 11 can be made of plastic.
[0063] In practice, the first connecting bar 12, the second connecting bar 13, and the third connecting bar 14 can be located on the side of the support plate 11 closer to the contactor, so that the first connecting bar 12, the second connecting bar 13, and the third connecting bar 14 can be electrically connected to the main circuit input terminal of the contactor.
[0064] The arrangement of the first connecting row 12, the second connecting row 13, and the third connecting row 14 on the support plate 11 is not specifically limited here.
[0065] For example, the first connecting row 12, the second connecting row 13, and the third connecting row 14 can be installed on the support plate 11 by means of riveting, snap-fitting, or welding.
[0066] like Figure 3 As shown, the first connecting bar 12 includes a first terminal 121, a first connecting part 122 and a second terminal 123 connected sequentially along a first direction, that is, the two ends of the first connecting part 122 are respectively connected to the first terminal 121 and the second terminal 123.
[0067] The first connecting strip 12 can be a split structure, that is, the first terminal 121, the first connecting part 122, and the second terminal 123 are set separately. During installation, the first terminal 121 and the second terminal 123 are respectively connected to the two ends of the first connecting part 122.
[0068] The connection method between the first terminal 121 and the first connecting part 122 is not specifically limited here. For example, the first terminal 121 and one end of the first connecting part 122 can be connected by welding, snap-fitting or threaded connection.
[0069] The connection method between the second terminal 123 and the first connecting part 122 is not specifically limited here. For example, the second terminal 123 can be connected to the other end of the first connecting part 122 by means of welding, snap-fit, or threaded connection.
[0070] In the embodiments provided in this application, the first connecting strip 12 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 121, the first connecting part 122, and the second terminal 123.
[0071] The material of the first connecting row 12 can be copper or aluminum, but it is not limited to these in practice.
[0072] The first terminal 121 and the second terminal 123 can extend along a second direction, which is perpendicular to the support plate 11. In the second direction, the cross-section of the first terminal 121 can remain consistent, which not only ensures the electrical connection area between the first terminal 121 and the contactor and ensures connection stability, but also ensures the heat dissipation effect of the first terminal 121.
[0073] Similarly, the cross-section of the second terminal 123 can remain consistent in the second direction.
[0074] like Figure 3 As shown, the first terminal 121 and the second terminal 123 are arranged along the first direction, and the first connecting part 122 is disposed on the support plate 11.
[0075] In fact, the first terminal 121 corresponds to the main circuit input terminal L3 of the first contactor 21, and the second terminal 123 corresponds to the main circuit input terminal L3 of the second contactor 22. The first connecting block 12 connects the main circuit input terminals L3 of the first contactor 21 and the second contactor 22 in series.
[0076] In actual connection, the first terminal 121 can be inserted into the first contactor 21, and the first terminal 121 can be electrically connected to the main circuit input terminal L3 of the first contactor 21. The second terminal 123 can be inserted into the second contactor 22, and the second terminal 123 can be electrically connected to the main circuit input terminal L3 of the second contactor 22.
[0077] The first connecting part 122 is disposed on the support plate 11, thereby disposing the first connecting row 12 on the support plate 11. The manner in which the first connecting part 122 is disposed on the support plate 11 is not specifically limited here.
[0078] For example, the first connecting part 122 can be installed on the support plate 11 by means of riveting, snap-fitting or welding.
[0079] In the embodiments provided in this application, the first connecting part 122 can be integrally injection molded with the support plate 11.
[0080] 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 1. On the other hand, it can reduce dimensional errors caused by assembly. At the same time, the first connecting part 122 and the supporting plate 11 are integrally injection molded, which can enhance the structural integrity of the conductive busbar 1 and improve its structural strength.
[0081] The first connecting part 122 is located in the first plane, and the first plane and the first direction are both parallel to the bearing plate 11.
[0082] like Figure 3As shown, the second connecting bar 13 includes a third terminal 131, a second connecting part 132 and a fourth terminal 133 connected sequentially along the first direction. That is, the two ends of the second connecting part 132 are respectively connected to the third terminal 131 and the fourth terminal 133, and the second connecting part 132 is disposed on the support plate 11.
[0083] The second connecting strip 13 can be a split structure, that is, the third terminal 131, the second connecting part 132, and the fourth terminal 133 are separately arranged. During installation, the third terminal 131 and the fourth terminal 133 are respectively connected to the two ends of the second connecting part 132.
[0084] The connection method between the third terminal 131 and the second connecting part 132 is not specifically limited here. For example, the third terminal 131 and one end of the second connecting part 132 can be connected by welding, snap-fitting or threaded connection.
[0085] The connection method between the fourth terminal 133 and the second connecting part 132 is not specifically limited here. For example, the fourth terminal 133 can be connected to the other end of the second connecting part 132 by means of welding, snap-fit, or threaded connection.
[0086] In the embodiments provided in this application, the second connecting strip 13 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 131, the second connecting part 132, and the fourth terminal 133.
[0087] The material of the second connecting row 13 can be copper or aluminum, but it is not limited to these in practice.
[0088] The third terminal 131 and the fourth terminal 133 can extend in the second direction.
[0089] In the second direction, the cross-section of the third terminal 131 can remain consistent, which not only ensures the electrical connection area between the third terminal 131 and the contactor and ensures connection stability, but also ensures the heat dissipation effect of the third terminal 131.
[0090] Similarly, the cross-section of the fourth terminal 133 can remain consistent in the second direction.
[0091] In fact, the third terminal 131 corresponds to the main circuit input terminal L2 of the first contactor 21, and the fourth terminal 133 corresponds to the main circuit input terminal L2 of the second contactor 22. The second connecting block 1313 connects the main circuit input terminals L2 of the first contactor 21 and the second contactor 22 in series.
[0092] In actual connection, the third terminal 131 can be inserted into the first contactor 21, and the third terminal 131 can be electrically connected to the main circuit input terminal L2 of the first contactor 21. The fourth terminal 133 can be inserted into the second contactor 22, and the fourth terminal 133 can be electrically connected to the main circuit input terminal L2 of the second contactor 22.
[0093] The second connecting part 132 is disposed on the support plate 11, thereby disposing the second connecting row 13 on the support plate 11. The manner in which the second connecting part 132 is disposed on the support plate 11 is not specifically limited here.
[0094] For example, the second connecting part 132 can be installed on the support plate 11 by means of riveting, snap-fitting or welding.
[0095] In the embodiments provided in this application, the second connecting part 132 can be integrally injection molded with the support plate 11.
[0096] 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 1. On the other hand, it can reduce dimensional errors caused by assembly. At the same time, the second connecting part 132 and the supporting plate 11 are integrally injection molded, which can enhance the structural integrity of the conductive busbar 1 and improve its structural strength.
[0097] The second connecting part 132 is located in the second plane, which is parallel to the bearing plate 11.
[0098] Please continue to refer to this. Figure 3 As shown, the third connection bar 14 includes a fifth terminal 141, a third connection part 142 and a sixth terminal 143 connected sequentially along the first direction, that is, the two ends of the third connection part 142 are connected to the fifth terminal 141 and the sixth terminal 143 respectively.
[0099] The third connecting strip 14 can be a split structure, that is, the fifth terminal 141, the third connecting part 142, and the sixth terminal 143 are set separately. During installation, the fifth terminal 141 and the sixth terminal 143 are respectively connected to the two ends of the third connecting part 142.
[0100] The connection method between the fifth terminal 141 and the third connecting part 142 is not specifically limited here. For example, the fifth terminal 141 and one end of the third connecting part 142 can be connected by welding, snap-fitting or threaded connection.
[0101] The connection method between the sixth terminal 143 and the third connecting part 142 is not specifically limited here. For example, the sixth terminal 143 can be connected to the other end of the third connecting part 142 by means of welding, snap-fit, or threaded connection.
[0102] In the embodiments provided in this application, the third connecting strip 14 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 141, the third connecting part 142, and the sixth terminal 143.
[0103] The material of the third connecting row 14 can be copper or aluminum, but it is not limited to these in practice.
[0104] The fifth terminal 141 and the sixth terminal 143 may extend in the second direction.
[0105] In the second direction, the cross-section of the fifth terminal 141 can remain consistent, which not only ensures the electrical connection area between the fifth terminal 141 and the contactor and ensures connection stability, but also ensures the heat dissipation effect of the fifth terminal 141.
[0106] Similarly, the cross-section of the sixth terminal 143 can remain consistent in the second direction.
[0107] In fact, the fifth terminal 141 corresponds to the main circuit input terminal L1 of the first contactor 21, and the sixth terminal 143 corresponds to the main circuit input terminal L1 of the second contactor 22. The third connecting block 14 connects the main circuit input terminals L1 of the first contactor 21 and the second contactor 22 in series.
[0108] In actual connection, the fifth terminal 141 can be inserted into the first contactor 21, and the fifth terminal 141 can be electrically connected to the main circuit input terminal L1 of the first contactor 21. The sixth terminal 143 can be inserted into the second contactor 22, and the sixth terminal 143 can be electrically connected to the main circuit input terminal L1 of the second contactor 22.
[0109] The third connecting part 142 is disposed on the support plate 11, thereby disposing the third connecting row 14 on the support plate 11. The manner in which the third connecting part 142 is disposed on the support plate 11 is not specifically limited here.
[0110] For example, the third connecting part 142 can be installed on the support plate 11 by means of riveting, snap-fitting or welding.
[0111] In the embodiments provided in this application, the third connecting row 14 can be integrally injection molded with the support plate 11.
[0112] 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 1. On the other hand, it can reduce dimensional errors caused by assembly. At the same time, the third connecting part 142 and the supporting plate 11 are integrally injection molded, which can enhance the structural integrity of the conductive busbar 1 and improve its structural strength.
[0113] In actual processing, the first connecting row 12, the second connecting row 13 and the third connecting row 14 can be cut and pressed into shape first, and then the first connecting row 12, the second connecting row 13 and the third connecting row 14 can be injection molded together with the support plate 11.
[0114] At least a portion of the third connection portion 142 is located within a third plane, which is parallel to the support plate 11.
[0115] In specific implementation, a portion of the third connecting part 142 may be located within the second plane, or the entire second connecting part 132 may be located within the second plane; no specific limitation is made here.
[0116] like Figure 3 As shown, the first terminal 121, the third terminal 131, the fifth terminal 141, the second terminal 123, the fourth terminal 133, and the sixth terminal 143 are arranged sequentially along the first direction.
[0117] Please combine Figure 1 and Figure 3 As shown, when the busbar 1 is connected to the first contactor 21 and the second contactor 22, the first terminal 121 is electrically connected to the main circuit input terminal L3 of the first contactor 21, and the second terminal 123 is electrically connected to the main circuit input terminal L3 of the second contactor 22. The third terminal 131 is electrically connected to the main circuit input terminal L2 of the first contactor 21, and the fourth terminal 133 is electrically connected to the main circuit input terminal L2 of the second contactor 22. The fifth terminal 141 is electrically connected to the main circuit input terminal L1 of the first contactor 21, and the sixth terminal 143 is electrically connected to the main circuit input terminal L1 of the second contactor 22.
[0118] Thus, by using the conductive busbar 1 provided in the embodiments of this application, the main circuit input terminals of the first contactor 21 and the second contactor 22 can be connected in series in phase.
[0119] In practical operation, by connecting the main circuit output terminals of the first contactor 21 and the second contactor 22 in a phase sequence cross-connection manner, the forward and reverse rotation of the motor can be achieved.
[0120] In the embodiments provided in this application, the first connecting portion 122 is located in the first plane, the second connecting portion 132 is located in the second plane, at least part of the third connecting portion 142 is located in the third plane, and the first plane, the second plane, and the third plane are parallel.
[0121] That is, the first connecting portion 122 and the second connecting portion 132 are not in the same plane, the first connecting portion 122 and at least part of the third connecting portion 142 are not in the same plane, and the second connecting portion 132 and at least part of the third connecting portion 142 are not in the same plane.
[0122] Compared to the prior art where the first connecting part 122, the second connecting part 132, and the third connecting part 142 are all in the same plane, the conductive bus 1 provided in this application embodiment can stagger the first connecting part 122, the second connecting part 132, and the third connecting part 142, which helps to increase the distance between the first connecting part 122, the second connecting part 132, and the third connecting part 142, effectively reducing the possibility of heat source concentration, facilitating the heat dissipation of the conductive bus 1, and improving the heat dissipation effect of the conductive bus 1.
[0123] In specific implementation, the structure of the first connecting part 122, the second connecting part 132, and the third connecting part 142 is not specifically limited here.
[0124] For example, the first connecting part 122 can be a long strip structure, and the second connecting part 132 can be a U-shaped structure. Of course, it is not limited to these in practice.
[0125] As an example, such as Figure 3 As shown, the third connecting part 142 includes a first connecting segment 1421 and a second connecting segment 1422. The first connecting segment 1421 is located in the third plane, and the second connecting segment 1422 is located in the first plane.
[0126] At this time, the first connecting part 122 and the second connecting segment 1422 are both located in the first plane, the second connecting part 132 is located in the second plane, and the first connecting segment 1421 is located in the third plane.
[0127] In a specific implementation, the third connecting part 142 also includes a bent section, the two ends of which are connected to the first connecting section 1421 and the second connecting section 1422, respectively.
[0128] As another example, the second plane coincides with the third plane.
[0129] At this time, the first connecting part 122 and the second connecting segment 1422 are both located in the first plane, and the second connecting part 132 and the first connecting segment 1421 are located in the same plane.
[0130] This makes it easier to reduce the space occupied by the first connecting part 122, the second connecting part 132, and the third connecting part 142 in the second direction, thereby improving the compactness of the busbar 1.
[0131] When the first connecting part 122, the second connecting part 132, and the third connecting part 142 are integrally injection molded with the support plate 11, ejector pins of the same length can be used to press against the first connecting part 122 and the second connecting part 1422 respectively, thereby positioning the first connecting part 122 and the third connecting part 142. Alternatively, ejector pins of the same length can be used to press against the second connecting part 132 and the first connecting part 1421 respectively, thereby positioning the second connecting part 132 and the third connecting part 142.
[0132] Furthermore, the third connecting portion 142 includes a first connecting segment 1421 and a second connecting segment 1422, wherein the first connecting segment 1421 is located in the second plane and the second connecting segment 1422 is located in the third plane.
[0133] Thus, the first connecting part 122 is located in the first plane, the second connecting part 132 and the first connecting segment 1421 are both located in the second plane, and the second connecting segment 1422 is located in the third plane.
[0134] The structure of the conductive busbar 1 has been enriched, making it easier to select and set according to actual conditions.
[0135] As an alternative, the second connecting part 132 is located in the second plane, the third connecting part 142 is located in the third plane, and the first plane, the second plane, and the third plane are arranged sequentially along the second direction.
[0136] Of course, it can also be set up so that the first plane, the third plane, and the second plane are arranged sequentially along the second direction.
[0137] This enriches the structural forms of the conductive busbar 1, making it easier to select and set according to actual conditions.
[0138] In some embodiments, the busbar 1 is used to connect the main circuit input terminals of two adjacent contactors in series in the same phase. One of a latch and a slot that cooperates with each other is provided on the side of the support plate 11 near the contactor, and the other of a latch and a slot is provided on the contactor.
[0139] At this time, when the conductor bus 1 is installed on the contactor, the slot and the buckle cooperate to improve the stability of the connection between the conductor bus 1 and the contactor.
[0140] Additionally, during the installation of the conductor busbar 1 onto the contactor, aligning the slot and the clip facilitates quick installation of the conductor busbar 1. This also effectively reduces the possibility of the conductor busbar 1 being installed backwards.
[0141] In practice, a latch can be provided on the support plate 11, and a corresponding slot can be provided on the contactor. Alternatively, a slot can be provided on the support plate 11, and a latch can be provided on the contactor.
[0142] The placement of the clips and slots is not specifically limited here and will depend on the actual situation. Similarly, the number of clips and slots is not specifically limited here.
[0143] As a feasible approach, such as Figure 2 As shown, the support plate 11 is provided with through holes corresponding to the first terminal 121, the second terminal 123, the third terminal 131, the fourth terminal 133, the fifth terminal 141 and the sixth terminal 143.
[0144] In this way, the terminals of the external power supply can pass through the through hole and be electrically connected to the corresponding main circuit input terminal of the contactor, which facilitates the electrical connection between the external power supply and the contactor.
[0145] Additionally, it should be noted that cage-type terminal blocks can be used to connect the corresponding external power supply terminals, busbars, and the main circuit input terminals of the contactor to ensure the stability of the electrical connection.
[0146] Please refer to Figure 1 and Figure 2 Wiring markings 15 are provided on the side of the support plate 11 away from the first connecting row 12.
[0147] At this point, the arrangement of the first connecting row 12, the second connecting row 13 and the third connecting row 14 within the carrier plate 11 can be shown more intuitively, making it easier for users to identify the purpose of the conductive row 1.
[0148] 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.
