Description

Technical Field

[0001] This invention relates to a modular contactor. Background Technology

[0002] Contactors are widely produced and used electrical control components, capable of frequently switching AC / DC main circuits and high-capacity control circuits. Contactors, in conjunction with relays, can achieve functions such as timed operation, interlocking control, quantitative control, voltage application, and undervoltage protection.

[0003] During operation, the contactor's breaking unit is prone to melting, the coil is easily overheated and burned out, and the circuit board is easily damaged. Existing contactors typically have an integrated structure, with the breaking unit, coil, and circuit board all housed in the same casing. When a contactor component fails, the entire contactor usually needs to be disassembled for repair or replacement, a time-consuming, labor-intensive, and inefficient process; alternatively, the entire contactor can be rendered unusable, increasing costs. Furthermore, disassembling the contactor usually requires disconnecting the cables / copper busbars, which also consumes considerable time.

[0033] Various embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that, in the drawings, the same reference numerals are assigned to components having substantially the same or similar structure and function, and repeated descriptions of them will be omitted. Unless otherwise specified, the terms "first side," "second side," "right side," "left side," etc., used herein are described with respect to the accompanying drawings. The description of "first" and its variations is merely for distinguishing components and does not limit the scope of the invention; "first component" may be written as "second component," etc., without departing from the scope of the invention.

[0034] The accompanying drawings in this specification are schematic diagrams used to help illustrate the concept of the invention, and schematically show the shape of each part and their interrelationship.

[0035] Below, refer to Figures 1 to 4 The different types of embodiments of the present invention will be described in detail.

[0036] like Figure 1-4As shown, the modular contactor of the present invention includes a drive module 1, an intermediate connection module 2, a disconnection module 3, an upper application interface module 4, and a lower application interface module 5. For simplicity, the intermediate connection module 2 is omitted from the diagram. It should be understood that the intermediate connection module 2 is located between the drive module 1 and the disconnection module 3 to support the drive module and the disconnection module, and to provide gas guiding components and reset components, etc.

[0037] For example, drive module 1 includes a stationary iron core, a coil, and control components; intermediate connection module 2 includes a moving iron core; and disconnection module 3 includes multiple disconnection units. Upper application interface module 4 and lower application interface module 5 each include multiple copper busbars for electrical connection to user terminals, allowing the modular contactor to be electrically connected to the main circuit of various applications as needed. The drive module is detachably connected to the first side of the intermediate connection module to drive the moving iron core under the control of the control components. The disconnection module is detachably connected to the second side of the intermediate connection module opposite to the first side, enabling the multiple disconnection units to open or close under the drive of the moving iron core. The upper application interface module is detachably connected to the top of the disconnection module to electrically connect to the upper stationary contacts of the multiple disconnection units. The lower application interface module is detachably connected to the bottom of the disconnection module to electrically connect to the lower stationary contacts of the multiple disconnection units.

[0038] Figure 1 A first embodiment of a modular contactor is shown, such as Figure 1 As shown, the disconnecting module 3 includes, for example, three disconnecting units, as indicated by the dashed boxes in the figure. These units are housed within a housing, namely the base housing. The modular contactor can be mounted on a mounting plate (the largest rectangular plate in the figure) via the base housing to secure the contactor in various applications. The upper application interface module 4 and the lower application interface module 5 are mounted on the top and bottom of the base housing, respectively, and thus connected to the top and bottom of the disconnecting module housed within the base housing. The drive module 1 is located on the side of the base housing housing containing the disconnecting module 3 away from the mounting plate.

[0039] Figure 2 A second embodiment of the modular contactor is shown, which is related to... Figure 1 The difference in the first embodiment is that the modular contactor is mounted on the mounting plate via the housing of the drive module 1. That is, Figure 2 The drive module 1 is located between the breakout module 3 and the mounting plate.

[0040] Figure 3 A third embodiment of the modular contactor is shown, which is related to... Figure 1 The difference in the first embodiment is that the three segmented units are each housed in their respective sub-shells, thus Figure 3The modular contactor does not include a base housing. The upper application interface module 4 and the lower application interface module 5 are respectively installed on the top and bottom of the disconnect module, and the modular contactor is mounted on the mounting plate through three sub-housings.

[0041] Figure 4 A fourth embodiment of the modular contactor is shown, which is related to... Figure 3 The structure is similar to that of the other two, except that the modular contactor is mounted on the mounting plate through the housing of the drive module 1, that is, the drive module 1 is located between the disconnect module 3 and the mounting plate.

[0042] In addition, such as Figure 1-4 As shown, the drive module 1 may include a power module 6 and a control module 7, with the power module 6 located above the control module 7. The power module includes, for example, a stationary iron core and a coil, while the control module includes, for example, a control component. For example, the power module 6 and the control module 7 are electrically connected via a flexible connection, allowing the control component, for example, in the form of a circuit board, to send trigger commands to power the coil in the power module. In other examples, the power module 6 may also be located below the control module 7, or the power module 6 and the control module 7 may be arranged side-by-side in a horizontal direction. For example, the power module and the control module may be detachably connected together via their respective housings, or detachably connected to a first side of an intermediate connecting module.

[0043] The positions of the modules of the modular contactor of the present invention are not limited to the above embodiments. In other examples, the drive module and the intermediate connection module may also be combined into one module, that is, both are housed in the same housing, and this module is detachably connected to the disconnect module.

[0044] Below, refer to Figures 5 to 7 The specific structure of the modular contactor according to the present invention will be described in detail.

[0045] Figure 5 An exploded view of the modular contactor is shown. Figure 6a and 6b for Figure 5 A schematic diagram showing the various modules of a modular contactor assembled together. Figure 7 This is a partial schematic diagram of a modular contactor, showing the connection method between the intermediate connection module and the disconnection module.

[0046] like Figure 5 and Figures 6a-6bAs shown, the modular contactor 100 includes a drive module 1, an intermediate connection module 2, a disconnection module 3, an upper application interface module 4, and a lower application interface module 5. The drive module 1 is detachably connected to a first side (the side facing the observer in the figure) of the intermediate connection module 2, and the disconnection module 3 is detachably connected to a second side (the side facing away from the observer in the figure) of the intermediate connection module 2 opposite to the first side. Furthermore, the modular contactor also includes a base housing 8, the intermediate connection module 2 is detachably connected to the base housing, and the disconnection module is housed within the base housing when the modules are assembled together. The upper application interface module 4 is detachably mounted on the top of the base housing 8, and thus detachably connected to the top of the disconnection module 3 housed within the base housing, enabling electrical connection to the upper stationary contacts of multiple disconnection units. The lower application interface module 5 is detachably mounted on the bottom of the base housing 8, and thus detachably connected to the bottom of the disconnection module 3 housed within the base housing, enabling electrical connection to the lower stationary contacts of multiple disconnection units.

[0047] like Figure 5 and Figures 6a-6b As shown, the drive module 1 housing contains a stationary iron core 9, a coil 10, and a control component 11. The control component 11, for example, is in the form of a circuit board and can send trigger commands to power the coil 10. Furthermore, quick-connect plugs exist between the control component and other components, eliminating the need for rewiring when repairing or replacing the control component, thus reducing time and cost.

[0048] like Figure 5-7 As shown, the intermediate connecting module 2 has a moving iron core 12, an elastic element 13, and a stop element 16 housed within its housing. The stop element 16 is located on one end of the moving iron core 12 near the disconnecting module 3. One end of the elastic element 13 is located on the housing of the intermediate connecting module, and the other end is located on the moving iron core. It is used to elastically bias the moving iron core in the open position, thereby separating the moving contact from the stationary contact of each disconnecting unit. The elastic element is, for example, a torsion spring.

[0049] In addition, such as Figure 5 As shown, the segmentation module 3 includes multiple segmentation units, for example, three segmentation units. Figure 5 As shown in Figure 6, each of the plurality of breaking units includes a connector 14 disposed on its moving contact and protruding beyond the housing of the breaking module. When the breaking unit has its own sub-housing, the connector 14 protrudes beyond the sub-housing.

[0050] like Figures 6a-6b As shown, when the modular contactors are assembled together, the disconnecting module is located on the second side of the intermediate connecting module (i.e., the right side of the intermediate module). The stop 16 separates the moving contact in the disconnecting unit from the stationary contact of the disconnecting unit through the connector 14, thereby keeping the disconnecting module open.

[0051] When coil 9 in the drive module is energized, the stationary iron core 10 generates an electromagnetic attraction, drawing the moving iron core 12 to the left. This, in turn, moves the stop 16 to the left. At this point, the stop no longer obstructs the connecting member 14, allowing the moving contact to move to the left under the action of its elastic element. When the moving iron core reaches its closed position, the moving contact contacts the stationary contact, thus closing the tripping module. When coil 9 is de-energized, under the elastic force of the elastic element 13, the moving iron core 12 moves to the right back to its open position, further moving the stop 16 to the right. At this point, the stop drives the connecting member 14 to move the moving contact to the right to separate from the stationary contact, thus opening the tripping module.

[0052] Figure 5 The diagram also illustrates different types of upper application interface modules 4 and lower application interface modules 5. The upper application interface module 4 includes multiple copper busbars 18 connected to terminal blocks, for example, three copper busbars 18, the number corresponding to the number of disconnection units. Another type of upper application interface module 4' includes, for example, three copper busbars 18'. Figures 6a-6b As shown, the copper busbars of the upper application interface module and the lower application interface are electrically connected to the user's wiring terminals via bolts. Figure 6a and Figure 6b As shown, the difference between the upper application interface module 4 and 4' is that the copper busbar 18 is flat and close to the upper stationary contact of the disconnecting unit, while the copper busbar 18' has a "C"-like shape and its portion connected to the terminal block is away from the upper stationary contact of the disconnecting unit. The lower application interface module 5 includes multiple copper busbars 19 connected to the terminal block, for example, three copper busbars 19, the number corresponding to the number of disconnecting units. Another type of upper application interface module 5' includes, for example, three copper busbars 19'. Figure 6a and Figure 6b As shown, the difference between the lower application interface module 5 and 5' is that the copper busbar 19 is flat, while the copper busbar 19' has a "C"-like shape and its portion connected to the terminal block is far from the lower stationary contact of the disconnecting unit. For example... Figure 6c As shown, the copper busbar 18" of the upper application interface module can also have a Z-shaped design, and the copper busbar of the lower application interface can also have a Z-shaped design. In this way, by selecting different types of application interface modules, users can adjust the position and height of the terminals connected to the copper busbar, thereby cooperating with upstream and downstream products, such as keeping it flush with the upstream protection circuit breaker. Therefore, the modular contactor of the present invention can be flexibly used in different situations without complicated wiring.

[0053] Below, for reference Figure 5 as well as Figure 7-10 The connection between the various modules of the modular contactor according to the present invention is described in detail.

[0054] Figure 8 This demonstrates how to connect the drive module to the rest of the modular contactor. (For example...) Figure 8 As shown, the housing of the drive module 1 has a plurality of first holes 21, for example, four first holes 21 located at the four corners of the housing of the drive module; the housing of the intermediate connecting module 2 has a plurality of second holes 20 on a first side that respectively mate with the plurality of first holes, for example, four second holes 20 located at the four corners of the housing of the intermediate connecting module 2. By screwing a plurality of screws into the plurality of first holes 21 and the plurality of second holes 20, the drive module 1 can be mounted on the first side of the housing of the intermediate connecting module 2. By unscrewing the plurality of screws from the plurality of first holes 21 and the plurality of second holes 20, the drive module 1 and the intermediate connecting module 2 assembled together can be disassembled. In other examples of the present invention, the drive module and the intermediate connecting module can be connected by snap-fit.

[0055] like Figure 5 and Figure 7 As shown, the housing of the splitting module 3 (e.g., a sub-housing of multiple splitting units) is provided with multiple third holes 17 and multiple hooks 15, for example, each splitting unit includes one third hole and one hook; the housing of the intermediate connecting module 2 is on the second side ( Figure 7 The right side of the intermediate connecting module 2 has multiple fourth holes 22 that mate with multiple third holes and multiple grooves 23 that mate with multiple hooks 15. For example, the housing of the intermediate connecting module 2 has three fourth holes 22 and three grooves 23, the number of which corresponds to the number of the breaking units. Each of the multiple breaking units is mounted on the second side of the housing of the intermediate connecting module by engaging the hooks 15 in the grooves 23, and each of the multiple breaking units is fixed to the second side by setting screws in the third and fourth holes. The breaking module can be removed from the housing of the intermediate connecting module by unscrewing the screws from the third and fourth holes and then, for example, moving the multiple breaking units of the breaking module upward.

[0056] Figure 9 This demonstrates how to mount the connected drive module, intermediate connection module, and disconnect module onto the base housing. (Example) Figure 9 As shown, the housing of the intermediate connecting module 2 has multiple fifth holes 25, such as two fifth holes at the top and two fifth holes at the bottom (not shown in the figure); the base housing 8 has multiple sixth holes 24 that mate with the multiple fifth holes 25. The intermediate connecting module is mounted on the base housing and the disconnect module is housed within the base housing by screwing multiple screws into the multiple fifth holes and multiple sixth holes. The assembled drive module, intermediate connecting module, and disconnect module can be detached from the base housing by unscrewing the screws from the fifth holes and multiple sixth holes.

[0057] Figure 10 This illustrates how the upper application interface module 4 is mounted on the base housing. The upper application interface module 4 includes multiple upper protrusions 26, and the top of the base housing 8 includes multiple upper recesses 27 that mate with the upper protrusions. Similarly, as... Figure 5 As shown, the lower application interface module 5 includes multiple lower recesses 28, and the bottom of the base housing 8 includes multiple lower protrusions 29 that mate with the lower recesses. For example, the upper application interface module 4 includes four upper protrusions 26, and the top of the base housing 8 includes four upper recesses 27; the lower application interface module 5 includes four lower recesses 28, and the bottom of the base housing 8 includes four lower protrusions 29. Figure 10 As shown, the size of the portion of the upper protrusion 26 furthest from the upper application interface module is larger than the size of the portion of the upper protrusion 26 closest to the upper application interface module, thus allowing it to snap into the upper groove 27 and preventing it from moving up or down. Figure 5 As shown, the size of the portion of the lower protrusion 29 away from the base shell is larger than the size of the portion of the lower protrusion 29 close to the base shell, so that it can be engaged in the lower groove 28 and cannot move up or down.

[0058] For example, by starting from one side of the base shell ( Figure 10 Pushing the upper application interface module 4 (on the right side) pushes the upper protrusion 26 into the upper groove 27, allowing the upper protrusion to be positioned within the groove, thus mounting the upper application interface module on top of the base housing. Then, by passing bolts through holes in the upper stationary contact and the copper busbar of the upper application interface module, the upper application interface module is secured to the base housing and the disconnect module. After removing the bolts, the upper application interface module 4 can be detached from the base housing by pushing it in the opposite direction to push the upper protrusion 26 out of the upper groove 27. The installation and removal of the lower application interface module 5 is similar to that of the upper application interface module 4; by positioning the lower protrusion in the lower groove, the lower application interface module can be mounted at the bottom of the base housing, and by separating the lower protrusion from the lower groove, the lower application interface module can be detached from the base housing.

[0059] When the disconnecting unit malfunctions and requires repair or periodic maintenance, the user can remove the assembled drive module, intermediate connection module, and disconnecting module from the base housing without disassembling the cable / copper busbar fastening bolts on the upper and lower application interface modules. This significantly reduces the time and cost required for maintenance and repair, lowers quality risks, and improves efficiency. Furthermore, when the coil or circuit board malfunctions and requires repair or periodic maintenance, the user can simply remove the drive module from the intermediate connection module for inspection, repair, or replacement without disassembling other modules or loosening the cable / copper busbar connections. This again significantly reduces the time and cost required for maintenance and repair, lowers quality risks, and improves efficiency.

[0060] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the invention to achieve the purpose of the invention.
