Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0035] To facilitate understanding of the connection plate technical solution of the embodiments of this application, the technical problem to be solved by the embodiments of this application will be explained first.

[0036] The following section will first explain the wiring on the back of the circuit breaker board, and then combine it with... Figure 1 This section explains the problems with the back-panel wiring structure of circuit breakers in some existing embodiments.

[0037] Rear-panel wiring of circuit breakers is an electrical installation method where the circuit breaker's terminals are located on the back of the equipment (near the mounting panel), and connected to external circuits through wiring holes or connectors on the back of the panel. This design is commonly used in compact spaces such as distribution cabinets and control boxes to improve safety and ease of maintenance.

[0038] refer to Figure 1 , Figure 1 A schematic diagram of the structure of a circuit breaker in some existing embodiments is shown. For example... Figure 1 As shown, to enable back-panel wiring of the circuit breaker, the circuit breaker includes a housing 5, a first connecting plate 1, a second connecting plate 2, two contact posts 3, and two connecting bars 4. The housing 5 has two first terminals 51, which are the outgoing terminal and the incoming terminal, respectively.

[0039] The first connecting plate 1 is located at the outlet end of the housing 5. The first end of the first connecting plate 1 is fixed inside the housing 5. The first end of the contact post 3 passes through the base of the housing 5 and is fastened to the second end of the first connecting plate 1 by means of nuts and spring washers. The second end of the contact post 3 is fastened to the first end of the connecting cable 4 by means of two sets of nuts and spring washers.

[0040] The second connecting plate 2 is located at the inlet end of the housing 5. Similarly, the first end of the second connecting plate 2 is fixed inside the housing 5. The first end of the contact post 3 passes through the base of the housing 5 and is fastened to the second end of the second connecting plate 2 by means of nuts and spring washers. The second end of the contact post 3 is fastened to the first end of the connecting cable 4 by means of two sets of nuts and spring washers.

[0041] The wiring of the circuit breaker requires the combination of multiple components (i.e., it requires a first connecting plate 1 / second connecting plate 2, contact post 3, multiple sets of nuts and flat spring washers). Not only is the installation process cumbersome and involves many parts, but also multiple links need to be tightened. If the operation is not done properly, it can easily lead to poor contact, increased contact resistance, and thus cause the temperature rise to be too high.

[0042] To address this issue, this application provides a circuit breaker comprising a housing and a conductive connection plate. The housing has a first terminal, and the conductive connection plate is integrally formed, with one end fixed inside the housing and the other end located outside the housing and connectable to a cable or a connecting cable strip. Compared to existing back-panel wiring structures, the circuit breaker provided in this application, due to its integrally formed conductive connection plate, eliminates the need for contact posts and multiple sets of nuts and spring washers, avoiding complex back-panel wiring structures and cumbersome installation processes. It is also simpler to manufacture and process, easier to install, more reliable in performance, and less prone to problems such as poor contact and excessive temperature rise.

[0043] The circuit breaker of this application embodiment will be described in detail below with reference to specific embodiments and accompanying drawings.

[0044] refer to Figure 2 , Figure 2 A schematic diagram of the circuit breaker according to an embodiment of this application is shown. Figure 2 As shown, the circuit breaker includes a housing 5 and a conductive connection plate 10. The housing 5 has two first terminals 51, one for output and one for input. The conductive connection plate 10 includes two terminals.

[0045] For example, the two conductive connecting plates 10 are similar in that each conductive connecting plate 10 includes an integrally formed electrical contact portion 6 and a wiring portion 7.

[0046] The energized portions 6 of the two conductive connecting plates 10 are respectively located at the outgoing and incoming ends and fixed inside the housing 5. It can be understood that the end of the energized portion 6 away from the wiring portion 7 can be electrically connected to the moving contact inside the circuit breaker housing 5. When the circuit is closed, the energized portion 6 is electrically connected to the moving contact, and when the circuit is opened, the electrical connection between the energized portion 6 and the moving contact is broken.

[0047] The wiring portions 7 of the two conductive connecting plates 10 are located outside the housing 5, and the wiring portions 7 include a second wiring terminal 71, which includes a wiring plane 711.

[0048] In some embodiments, the second terminal 71 may include a first wiring hole 712, which penetrates the wiring plane 711. The first wiring hole 712 can be used to connect a cable or a connector 4 (…). Figure 2 As shown in the diagram, specifically, the first wiring hole 712 can be made to pass through the hole on the connecting strip 4, and then a fixed connection can be achieved by the stud 8, thereby realizing the surface-to-surface fixation between the wiring plane 711 and the connecting strip 4. This connection method can effectively increase the contact area between the wiring part 7 and the connecting strip 4, firstly making the two fit more reliably, and secondly reducing resistance and temperature rise, making the connection between the cable and the inside of the circuit breaker housing 5 more firm and reliable.

[0049] In some embodiments, the second terminal 71 may not include the first terminal hole 712. When the first terminal hole 712 is not provided, the second terminal 71 of the wiring portion 7 can be fixed to the connecting bar 4 by plugging in, realizing the plug-in connection of the circuit breaker. This connection method makes the wiring and use of the circuit breaker more convenient and efficient.

[0050] In some embodiments, such as Figure 2 As shown, both surfaces of the second terminal 71 in the thickness direction are wiring planes 711, which makes the connection with the cable or connecting strip 4 more reliable. Of course, in some other embodiments, the surface of the second terminal 71 in the thickness direction that is close to the connecting strip 4 can be set as a wiring plane 711. The surface of the second terminal 71 in the thickness direction that is not close to the connecting strip 4 can be set as any shape such as arc, concave, or convex, which can also achieve a fixed connection with the connecting strip 4. This application does not limit this.

[0051] In some embodiments, such as Figure 2 As shown, the wiring portion 7 can be a flat plate structure. Of course, in some other embodiments, the wiring portion 7 can also be a structure consisting of any straight lines and / or curves, and this application embodiment does not limit this.

[0052] Compared to the post-connection method in existing technologies, the circuit breaker in this embodiment uses an integrally molded conductive connection plate 10. The advantages of this structure are: firstly, it reduces the number of parts, simplifies the structure, and facilitates manufacturing; secondly, it facilitates installation and connection, requiring only the contacting part 6 of the conductive connection plate 10 to be fixed inside the housing 5, while the wiring part 7 extends directly; and thirdly, it eliminates the need for nuts, spring washers, or other components for fixing, reducing the likelihood of poor contact and temperature rise in the circuit breaker, thus reducing potential failure points and lowering the risk of malfunctions due to loose connections or poor contact.

[0053] The conductive connecting plate 10 of this application will be described in detail below with reference to specific embodiments of this application.

[0054] First, combine Figures 3-6 For the circuit breaker housing (see reference) Figure 2 The conductive connection plate 10 at the outlet end of the housing 5) shown in the figure will be described in detail for the electrical connection part 6.

[0055] refer to Figure 3 , Figure 3 A schematic diagram of the conductive connecting plate 10 according to the first embodiment of this application is shown. The end of the energized portion 6 furthest from the first terminal 51 is provided with a limiting hole 601 and a magnetically conductive hole 602. The limiting hole 601 is connected to the housing (see reference). Figure 2 The limiting component inside the housing 5) shown is fixedly connected to prevent shaking. The magnetic guide hole 602 is connected to the housing (see reference). Figure 2 The magnetic sheet inside the housing 5) shown is connected so that the circuit breaker can collect current.

[0056] Understandably, the casing (see reference) Figure 2 The limiting component inside the housing 5) shown can be a limiting post, which passes through the limiting hole 601 to achieve a fixed connection between the two. Of course, other methods can also be used, and this application embodiment does not limit this. In addition, the housing (see reference) Figure 2 The magnetic sheet inside the housing 5) shown can also be a magnetic sheet with a bump shape, which passes through the magnetic hole 602 to achieve the connection between the two. Of course, other methods can also be used, and this application embodiment does not limit this.

[0057] In some embodiments, continue to refer to Figure 3 The electrical connection part 6 includes a plate-like structure, which has the aforementioned limiting hole 601 and magnetic guide hole 602, so that it can connect with the housing (see reference). Figure 2 The limiting components inside the housing 5) shown are more stable and secure when fixed and connected to the magnetic sheet. For example, the limiting holes 601 are symmetrically distributed on both sides of the plate-like structure, thereby enhancing the stability of the connection of the conductive connecting plate 10.

[0058] In some embodiments, continue to refer to Figure 3 The plate-like structure can extend in the same direction as the wiring part 7, forming a straight plate. This conductive connection plate 10 has a relatively simple structure, making it easy to connect and manufacture.

[0059] Therefore, as can be seen from the structure of the conductive connecting plate 10 shown in the first embodiment of this application, the conductive connecting plate 10 is precisely positioned and fixed to the housing 5 by the power receiving part 6 on the conductive connecting plate 10, and the conductive connecting plate 10 is reliably connected to the cable or connecting strip 4 by the wiring part 7 on the conductive connecting plate 10, so that the conductive connecting plate 10 can be adapted to cables of different specifications, thereby improving the applicability of the conductive connecting plate 10.

[0060] refer to Figure 4 , Figure 4 A schematic diagram of the structure of the conductive connecting plate 10 according to the second embodiment of this application is shown. Figure 4 The conductive connecting plate 10 shown is... Figure 3 Compared to the conductive connecting plate 10 shown, the difference lies in the specific structure of the plate-like structure included in the connecting part 6, while the rest of the structure is the same (i.e., the structure of the wiring part 7, the second wiring terminal 71 on the wiring part 7, the wiring plane 711 included in the second wiring terminal 71, and the first wiring hole 712 on the wiring plane 711 are the same). The following details... Figure 4 The specific structure of the plate-like structure included in the power-connecting part 6 shown will be described in detail, and the similarities will not be repeated.

[0061] like Figure 4 As shown, the plate-like structure includes a first mounting plate 61 and a second mounting plate 62. The first end 611 of the first mounting plate is connected to the wiring portion 7 and is angled relative to the wiring portion 7. One end of the second mounting plate 62 is connected to the second end 612 of the first mounting plate and is angled relative to the first mounting plate 61. The first end 611 and the second end 612 of the first mounting plate are opposite ends. This arrangement allows the power connection portion 6 to extend flexibly along the opposite ends of the first mounting plate 61 to accommodate the housing (see reference). Figure 2 The internal spatial layout of the shell 5 shown.

[0062] In this embodiment, as Figure 4 As shown, the second mounting plate 62 is provided with a limiting hole 601 and a magnetic guide hole 602 at the end away from the first mounting plate 61. In some other embodiments, the limiting hole 601 and the magnetic guide hole 602 may also be provided on other plates. This application embodiment does not limit this.

[0063] In some embodiments, such as Figure 4 As shown, the angle between the second mounting plate 62 and the first mounting plate 61 is 90 degrees, and the angle between the first mounting plate 61 and the wiring portion 7 is also 90 degrees. Overall, the conductive connection plate 10 has an approximate Z-shaped structure. In other embodiments, the angle between the second mounting plate 62 and the first mounting plate 61 can be acute or obtuse, and the angle between the first mounting plate 61 and the wiring portion 7 can also be acute (e.g., 30 degrees, 40 degrees) or obtuse (e.g., 100 degrees, 150 degrees). Those skilled in the art can customize the design based on different housings (see reference...). Figure 2 The internal spatial layout of the casing 5) shown can be flexibly adjusted at the angle to form irregularly shaped wiring, which can avoid interference with the circuit breaker casing (see reference). Figure 2 Other structures in the housing 5 shown may have an impact, but this application embodiment does not limit this.

[0064] In some embodiments, such as Figure 4 As shown, the second mounting plate 62 and the wiring portion 7 can be located on opposite sides of the plane containing the first mounting plate 61. For example, if the plane containing the first mounting plate 61 is horizontal, the second mounting plate 62 can be located above that horizontal plane, and the wiring portion 7 can be located below that horizontal plane. This arrangement allows the second mounting plate 62 and the wiring portion 7 to extend in different directions.

[0065] Therefore, according to Figure 4 As can be seen from the structure of the conductive connecting plate 10 shown, the plate-like structure in the power receiving part 6 includes a first mounting plate 61 and a second mounting plate 62 arranged in different directions, so that a three-dimensional spatial rigid frame is formed between the power receiving part 6 and the wiring part 7. This can effectively resist mechanical stress in different directions and avoid deformation caused by force in one direction. Furthermore, it can adapt to different housings (see reference). Figure 2 The internal spatial layout of the housing 5) shown makes the conductive connecting plate 10 and the housing (see reference) so that Figure 2 The base of the housing 5 shown is securely fastened while avoiding affecting the housing (see reference). Figure 2 Other structures in the shell shown in 5).

[0066] refer to Figure 5 and Figure 6 , Figure 5 A schematic diagram of the structure of the conductive connecting plate 10 according to the third embodiment of this application is shown. Figure 6 A schematic diagram of the structure of the conductive connecting plate 10 according to the fourth embodiment of this application is shown. Figure 5 and Figure 6 The conductive connecting plate 10 shown is... Figure 4The difference lies in the positional relationship between the first end 611 and the second end 612 of the first mounting plate, while the rest of the structure is the same (i.e., the wiring portion 7, the second wiring terminal 71 on the wiring portion 7, the wiring plane 711 included in the second wiring terminal 71, the first wiring hole 712 on the wiring plane 711, the first mounting plate 61, the second mounting plate 62, and the limiting hole 601 and the magnetic guide hole 602 located on the second mounting plate 62 are the same). The following is in conjunction with... Figure 5 and Figure 6 The differences will be explained in detail, while the similarities will not be repeated.

[0067] exist Figure 5 and Figure 6 In the conductive connection plate 10 shown, the first end 611 and the second end 612 of the first mounting plate are two adjacent ends. Specifically, as shown... Figure 5 As shown, the first end 611 is located at Figure 5 On the right side of the second end 612, while Figure 6 In the middle, the first end 611 is located Figure 6 The left side of the second end 612 in the middle.

[0068] Those skilled in the art will understand that, due to the change in the positional relationship between the first end 611 and the second end 612 of the first mounting plate, Figure 5 and Figure 6 The conductive connecting plate 10 shown no longer forms an approximate Z-shaped structure when viewed as a whole.

[0069] Figure 5 and Figure 6 The conductive connecting plate 10 shown is, with Figure 4 In comparison, although the positional relationship between the first end 611 and the second end 612 of the first mounting plate has changed, from an opposite relationship to an adjacent relationship, it can still form a three-dimensional rigid frame, and still effectively resist mechanical stress in different directions and adapt to different shells (see reference). Figure 2 The advantages of the internal space layout of the shell 5 shown. Additionally, Figure 5 and Figure 6 The conductive connecting plate 10 shown has a different design than the one shown. Figure 4 The structural design improves the flexibility and expandability of the conductive connection plate 10, achieving a large degree of adaptability with minor modifications.

[0070] Understandable Figures 4-6 In the corresponding conductive connection plate 10, the second mounting plate 62 can be connected to the housing (see reference). Figure 2 The moving contacts inside the housing 5) shown are electrically connected, thereby realizing the electrical connection between the conductive connection plate 10 and the inside of the circuit breaker housing.

[0071] in addition, Figures 4-6 In the corresponding conductive connection plate 10, the wiring part 7 is connected to the housing (see reference). Figure 2 The first terminal of the housing 5 shown (refer to) Figure 2 The first terminal 51 shown extends in different directions. This structure provides multi-angle operating space during installation and wiring, thus adapting to different wiring logics.

[0072] The above embodiments combined Figures 4-6 The following describes two configurations: one where the plate-like structure of the power-connecting part 6 extends in the same direction as the wiring part 7, and another where the plate-like structure includes only the first mounting plate 61 and the second mounting plate 62. In other embodiments, the plate-like structure of the power-connecting part 6 may include more mounting plates and connection methods, which will be described in detail below. Figures 7-10 For the circuit breaker housing (see reference) Figure 2 The conductive connecting plate 10 at the wire inlet end of the housing 5) shown in the diagram will be described in detail for its power receiving portion 6. In the following embodiments, the plate-like structure of the power receiving portion 6 includes a connecting plate, a third mounting plate, and a folding plate, which will be described in detail below.

[0073] refer to Figure 7 , Figure 7 A schematic diagram of the conductive connecting plate 10 according to the fifth embodiment of this application is shown. Figure 7 The conductive connecting plate 10 shown is... Figure 3 Compared to the conductive connecting plate 10 shown, the difference lies in the specific structure of the plate-like structure included in the power-connecting part 6, while the rest of the structure is the same (i.e., the structures of the wiring part 7, the second wiring terminal 71 on the wiring part 7, the wiring plane 711 included in the second wiring terminal 71, and the first wiring hole 712 on the wiring plane 711 are the same). Specifically, the plate-like structure of the power-connecting part 6 includes a connecting plate 9, a third mounting plate 63, and a folding plate 68. The following is in conjunction with... Figure 7 The structure of the plate-like structure of the electrical connection part 6 will be described in detail, and the similarities will not be repeated.

[0074] like Figure 7 As shown, in this embodiment, the plate-like structure includes: a connecting plate 9, a third mounting plate 63, and a folding plate 68. The first end of the third mounting plate 63 is connected to the connecting plate 9 and is angled. One end of the folding plate 68 is connected to the second end of the third mounting plate 63 via a bent plate, and the folding plate 68 is inclined towards the third mounting plate 63. Furthermore, the folding plate 68 is spaced apart from both the connecting plate 9 and the third mounting plate 63, and the other end of the folding plate 68 is provided with a magnetic guide hole 602. This structure with the folding plate 68 can further improve the conductivity between the conductive connecting plate 10 and the housing (see reference). Figure 2 The stability of the connection between the shells 5 shown.

[0075] In some embodiments, such as Figure 7 As shown, the connecting plate 9 specifically includes a fourth mounting plate 64 and a fifth mounting plate 65. The first end 641 of the fourth mounting plate is connected to the wiring portion 7, and the extension direction of the fourth mounting plate 64 is consistent with that of the wiring portion 7. The fifth mounting plate 65 is connected to the second end 642 of the fourth mounting plate and is angled relative to the fourth mounting plate 64. The first end 641 and the second end 642 of the fourth mounting plate are two opposite ends. The first end of the third mounting plate 63 is connected to the first end 641 of the fourth mounting plate and is angled relative to the fourth mounting plate 64. The fifth mounting plate 65 has a second wiring hole 651, which can extend out of the housing (see reference). Figure 2 The housing 5 shown in the diagram is then connected to cables or a connector 4, which provides a front-panel wiring method for the circuit breaker. Wiring can be performed using the second wiring hole 651 when needed.

[0076] In some embodiments, such as Figure 7 As shown, the angle between the fifth mounting plate 65 and the fourth mounting plate 64 is 90 degrees, and the angle between the first end of the third mounting plate 63 and the fourth mounting plate 64 is 90 degrees. The fifth mounting plate 65, the fourth mounting plate 64, and the third mounting plate 63 form an approximate Z-shaped structure. In other embodiments, the angle between the fifth mounting plate 65 and the fourth mounting plate 64 can be acute or obtuse, and the angle between the first end of the third mounting plate 63 and the fourth mounting plate 64 can also be acute or obtuse. Those skilled in the art can customize the design according to different housings (see reference). Figure 2 The internal spatial layout of the casing 5) shown can be flexibly adjusted at the angle to form irregularly shaped wiring, thereby avoiding interference with the circuit breaker casing (see reference). Figure 2 Other structures in the housing 5 shown may have an impact, but this application embodiment does not limit this.

[0077] In some embodiments, such as Figure 7 As shown, the fifth mounting plate 65 and the third mounting plate 63 can be located on opposite sides of the plane containing the fourth mounting plate 64. For example, if the plane containing the fourth mounting plate 64 is a vertical plane, then the fifth mounting plate 65 can be located to the right of that vertical plane, and the third mounting plate 63 can be located to the left of that vertical plane. This arrangement allows the fifth mounting plate 65 and the third mounting plate 63 to extend in different directions.

[0078] In some embodiments, such as Figure 7 As shown, the third mounting plate 63 is provided with a first weight-reduction hole 631. The first weight-reduction hole 631 is used to reduce weight and save materials.

[0079] Therefore, according to Figure 7As can be seen from the structure of the conductive connecting plate 10 shown, by designing a connecting plate 9, a third mounting plate 63, and a folding plate 68 in the plate-like structure of the energized part 6, wherein the connecting plate 9 further includes a fourth mounting plate 64 and a fifth mounting plate 65, and the structural design is as described above, it will not be repeated here. Therefore, the conductive connecting plate 10 in this embodiment also has the ability to effectively resist mechanical stress in different directions and adapt to different housings (see reference). Figure 2 The internal space layout of the housing 5 shown has advantages. Furthermore, the third mounting plate 63 extends outward compared to the wiring portion 7, which provides more possibilities for the structural expansion of the conductive connection plate 10, allowing the conductive connection plate 10 to be adapted to the housing (see reference). Figure 2 The shell 5 shown has a more irregular cavity layout. Moreover, the use of a multi-stage bending structure in the plate structure further improves the spatial adaptability of the conductive connection plate 10.

[0080] refer to Figure 8 , Figure 8 A schematic diagram of the structure of the conductive connecting plate 10 according to the sixth embodiment of this application is shown. Figure 8 The conductive connecting plate 10 shown is... Figure 7 The difference lies in the specific structure of the connecting plate 9 in the plate-like structure. Figure 8 The conductive connecting plate 10 shown has added a sixth mounting plate 66 and a seventh mounting plate 67, and removed the fourth mounting plate 64 and the fifth mounting plate 65, while the remaining structures are the same (i.e., the wiring portion 7, the second wiring terminal 71 on the wiring portion 7, the wiring plane 711 included in the second wiring terminal 71, the first wiring hole 712 on the wiring plane 711, the third mounting plate 63, the first weight reduction hole 631 on the third mounting plate 63, the folding plate 68, and the magnetic guide hole 602 on the folding plate 68 are the same structures). The following is in conjunction with... Figure 8 The differences will be explained in detail, while the similarities will not be repeated.

[0081] like Figure 8 As shown, the connecting plate 9 may further include a sixth mounting plate 66 and a seventh mounting plate 67. The first end 661 of the sixth mounting plate is connected to the wiring portion 7 and is angled relative to the wiring portion 7. The first end of the seventh mounting plate 67 is connected to the second end 662 of the sixth mounting plate and is angled relative to the sixth mounting plate 66.

[0082] Furthermore, in this embodiment, the third mounting plate 63 is not connected to the wiring portion 7, and the first end of the third mounting plate 63 is connected to the second end of the seventh mounting plate 67 and is set at an angle to the seventh mounting plate 67.

[0083] In some implementations, such as Figure 8As shown, the first end 661 and the second end 662 of the sixth mounting plate are two opposing ends. This arrangement allows the power-connecting portion 6 to extend flexibly along the opposing ends of the sixth mounting plate 66 to accommodate the housing (see reference). Figure 2 The internal spatial layout of the shell 5 shown.

[0084] In some implementations, such as Figure 8 As shown, the angle between the sixth mounting plate 66 and the wiring portion 7 can be 90 degrees, the angle between the seventh mounting plate 67 and the sixth mounting plate 66 can be 90 degrees, and the angle between the third mounting plate 63 and the seventh mounting plate 67 can be 90 degrees. The sixth mounting plate 66, the seventh mounting plate 67, and the third mounting plate 63 form an approximately Z-shaped structure. Of course, the angle between the sixth mounting plate 66 and the wiring portion 7 can also be an acute or obtuse angle, the angle between the seventh mounting plate 67 and the sixth mounting plate 66 can also be an acute or obtuse angle, and the angle between the third mounting plate 63 and the seventh mounting plate 67 can also be an acute or obtuse angle; this embodiment does not limit this.

[0085] In some embodiments, such as Figure 8 As shown, the seventh mounting plate 67 and the wiring portion 7 can be located on the same side of the plane containing the sixth mounting plate 66. For example, if the plane containing the sixth mounting plate 66 is horizontal, then both the seventh mounting plate 67 and the wiring portion 7 can be located below that horizontal plane. This arrangement creates an opening between the seventh mounting plate 67, the sixth mounting plate 66, and the wiring portion 7 for better engagement with the circuit breaker housing (see reference). Figure 2 The interior of the shell shown in Figure 5).

[0086] In some implementations, such as Figure 8 As shown, in addition to the first weight-reducing hole 631 on the third mounting plate 63, the seventh mounting plate 67 can also be provided with a second weight-reducing hole 671, with the first weight-reducing hole 631 and the second weight-reducing hole 671 being interconnected. This arrangement further saves materials.

[0087] Therefore, according to Figure 8 As can be seen from the structure of the conductive connecting plate 10 shown, by providing a sixth mounting plate 66 and a seventh mounting plate 67 in the connecting plate 9, the conductive connecting plate 10 is mounted on the housing (see reference). Figure 2 The installation and wiring in the housing 5 shown provides multi-angle operating space to accommodate different wiring logics.

[0088] refer to Figure 9 and Figure 10 , Figure 9 A schematic diagram of the conductive connecting plate 10 according to the seventh embodiment of this application is shown. Figure 10A schematic diagram of the structure of the conductive connecting plate 10 according to the eighth embodiment of this application is shown.

[0089] Figure 9 and Figure 10 The conductive connecting plate 10 shown is... Figure 8 The difference lies in the positional relationship between the first end 661 and the second end 662 of the sixth mounting plate, while the rest of the structure is the same (i.e., the wiring part 7, the second wiring terminal 71 on the wiring part 7, the wiring plane 711 included in the second wiring terminal 71, the first wiring hole 712 on the wiring plane 711, the third mounting plate 63, the first weight-reducing hole 631 on the third mounting plate 63, the folding plate 68, the magnetic guide hole 602 on the folding plate 68, the sixth mounting plate 66, the seventh mounting plate 67, and the second weight-reducing hole 671 on the seventh mounting plate 67 are the same). The following is in conjunction with... Figure 9 and Figure 10 The differences will be explained in detail, while the similarities will not be repeated.

[0090] like Figure 9 and Figure 10 As shown, the first end 661 and the second end 662 of the sixth mounting plate are two adjacent ends. Specifically, as... Figure 9 As shown, the first end 661 of the sixth mounting plate is located to the right of the second end 662 of the sixth mounting plate, as... Figure 10 As shown, the first end 661 of the sixth mounting plate is located to the right of the second end 662 of the sixth mounting plate.

[0091] Therefore, according to Figure 9 and Figure 10 As can be seen from the structure of the conductive connecting plate 10 shown, Figure 9 and Figure 10 The conductive connecting plate 10 shown has a different design than the one shown. Figure 8 The structural design specifically involves adjusting the positional relationship between the first end 661 and the second end 662 of the sixth mounting plate. This improves the flexibility and expandability of the conductive connection plate 10, and achieves a large compatibility through minor modifications.

[0092] Understandable Figures 7-10 In the corresponding conductive connecting plate 10, the folding plate 68 can connect with the housing (see reference). Figure 2 The moving contacts inside the housing 5) shown are electrically connected, thereby achieving electrical connection between the conductive connection plate 10 and the inside of the circuit breaker housing. Additionally, Figures 7-10 The corresponding conductive connecting plate 10 can also form a three-dimensional rigid frame, which can effectively resist mechanical stress in different directions and adapt to different shells (see reference). Figure 2 The advantages of the internal space layout of the shell 5 shown.

[0093] As can be seen from the various embodiments provided in this application above, regardless of whether it is in the circuit breaker housing (see reference) Figure 2 The outlet or inlet terminal of the housing 5 shown (refer to...) Figure 2 The first terminal 51 shown and the conductive connecting plate 10 can have various shapes and structures to resist mechanical stress in different directions and adapt to different housings (see reference). Figure 2 The internal layout of the housing 5) shown has good expandability and space adaptability of the conductive connection plate 10.
