[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

Therefore, the first component discussed below may be referred to as the second component without departing from the teachings of this application. As used herein, the term "and / or" includes any and all combinations of any one or more of the associated listed items.
[0042] In the description of this application, "multiple" means two or more, and "at least one" means one, two, or more, unless otherwise explicitly specified. In the description of this application, "perpendicular" means completely perpendicular to 90° or almost completely perpendicular, for example, an angle of 80° to 100° is considered perpendicular. Similarly, "parallel" means completely parallel or almost completely parallel, for example, a completely parallel angle of 10° is considered parallel.
[0043] It should also be noted that in the accompanying drawings of this application, arrows labeled X indicate the first direction X, arrows labeled Y indicate the second direction Y, and arrows labeled Z indicate the third direction Z. The introduction of the first direction X, the second direction Y, and the third direction Z is for the convenience of describing the structural positional relationship of the partition device, thereby facilitating understanding of its structure. In the embodiments of this application, the first direction X is the length direction of the first partition member 100; the second direction Y is the width direction of the first partition member 100; and the third direction Z is the thickness direction of the first partition member 100, which is also the engagement direction between the first partition member 100 and the second partition member 200. Furthermore, the first direction X, the second direction Y, and the third direction Z intersect each other, and more specifically, they are perpendicular to each other.
[0044] In the design of electrical cabinets, electrical clearance is a crucial consideration to meet safety regulations. This requirement necessitates a significant gap between the wiring busbars or electrical components and the sheet metal parts. However, due to space constraints, most products are designed to minimize the distance between electrical components or busbars. To properly address issues such as electrical clearance and arcing, adding partition components between busbars or electrical components has become a common solution.
[0045] Currently, conventional partition components typically achieve isolation by gluing branch boards to the main board. However, this structure has several drawbacks. Under prolonged high temperatures, the adhesive is prone to aging, causing the branch PC boards to detach and compromising reliability. Furthermore, during production, this method is difficult to position, and the stability of the adhesive is hard to control, severely impacting production efficiency.
[0046] In view of this, embodiments of this application provide a partition device designed to significantly improve the stability of the connection, thereby solving at least some of the aforementioned technical problems.
[0047] Please see Figure 1 , Figure 2 , Figure 3 This embodiment provides a partition device, which includes a first partition 100 and a second partition 200. The first partition 100 includes a first body 110 and a first snap-fit portion 120 connected to each other. The first body 110 has a first through hole 111, and the first snap-fit portion 120 is disposed on one side of the first through hole 111. The second partition 200 includes a second body 210, a first partition portion 220 connected to the second body 210, and a second snap-fit portion 230 disposed on the first partition portion 220. The second body 210 is located on the side of the first body 110 opposite to the first snap-fit portion 120. The first partition portion 220 passes through the first through hole 111 so that the second snap-fit portion 230 and the first snap-fit portion 120 engage.
[0048] It should be noted that the first body 110 may be plate-shaped and parallel to the surface of the object to be partitioned 300. The function of the first body 110 is to provide the main support structure for the entire first partition 100. A first through hole 111 penetrates the first body 110 along the second direction Y. A first snap-fit portion 120 is provided on the side of the first body 110 facing the object to be partitioned 300 and extends in the direction of the object to be partitioned 300. The second body 210 is parallel to the first body 110. A first partition portion 220 extends along the third direction Z. The size of the first partition portion 220 in the second direction Y is larger than the size of the object to be partitioned 300, and the size of the first partition portion 220 in the third direction Z is larger than the size of the object to be partitioned 300.
[0049] Specifically, the first partition 220 passes through the first through hole 111, thereby defining the relative positions of the first partition 100 and the second partition 200 in the horizontal direction (the horizontal direction refers to the first direction X and the second direction Y). The engagement process of the first engaging part 120 and the second engaging part 230 is as follows: the second engaging part 230 extends toward the second body 210, and the second engaging part 230 passes through the first through hole 111 together with the first partition 220. During the insertion process, the side of the second engaging part 230 away from the first partition 220 abuts against the side of the first engaging part 120 facing the first partition 220 and deforms until the minimum distance is reached between the first body 110 and the second body 210. At this time, the second latching part 230 returns to its original state, and its end away from the first partition part 220 abuts against the end of the first latching part 120 away from the first body 110, thereby realizing the limitation of the relative position of the first partition 100 and the second partition 200 in the third direction Z.
[0050] In view of this, this embodiment uses a snap-fit connection between the first partition 100 and the second partition 200, instead of relying on adhesive as in traditional methods, effectively solving the problem of component detachment due to adhesive aging in high-temperature environments. Workers can quickly assemble the first partition 100 and the second partition 200 according to the design structure, reducing production difficulty and time, thereby improving overall production efficiency. This partition device provides a reliable solution to electrical clearance or arcing problems in electrical cabinets. It can effectively isolate copper busbars or electrical components, ensuring the safe operation of electrical equipment, while also taking into account space constraints in product design.
[0051] In some embodiments, the orthographic projection of the first latching portion 120 on the second body 210 partially overlaps with the orthographic projection of the second latching portion 230 on the second body 210. It should be noted that this is to ensure that the first latching portion 120 and the second latching portion 230 can smoothly achieve relative latching. When the second latching portion 230 passes through the first through hole 111, in the third direction Z, the second latching portion 230 needs to have a certain overlap area with the first latching portion 120. Only in this way, when the distance between the first body 110 and the second body 210 gradually decreases to its minimum, can the end of the second latching portion 230 away from the first partition portion 220 accurately abut against the end of the first latching portion 120 away from the first body 110, thereby effectively defining the relative position of the first partition member 100 and the second partition member 200 in the third direction Z.
[0052] Furthermore, to avoid the first engaging portion 120 and the second engaging portion 230 failing to engage smoothly due to overlap in the third direction Z, at least one of the two engaging portions, 230 or 120, should be configured as an elastic element, possessing the ability to elastically deform. Taking the second engaging portion 230 as an example, during the process of the second engaging portion 230 passing through the first through hole 111, once the second engaging portion 230 comes into contact with the first engaging portion 120, due to the elastic characteristics of the second engaging portion 230, it will elastically deform under the contact force, thus cleverly avoiding obstacles and continuing the passing action. When the first body 110 and the second body 210 reach their minimum distance, the second engaging portion 230 will recover its original shape due to its elasticity, achieving a tight contact with the first engaging portion 120 and a stable engagement effect. This design, which incorporates the second snap-fit part 230 as an elastic element, not only cleverly solves the snap-fit problem that may arise from overlapping components, but also greatly enhances the flexibility and operability of the entire partition device during assembly. Simultaneously, the elastic snap-fit design can absorb stress caused by vibration, thermal expansion and contraction, and other factors to a certain extent, further enhancing the stability and reliability of the partition device under complex operating conditions. This ensures that it can perform its partitioning function stably and for a long time, providing a solid guarantee for the safe operation of related equipment.
[0053] The partition device in this embodiment is detachable. Due to the elastic properties of the second latching portion 230, during disassembly, the second latching portion 230 is pried away from the first latching portion 120. During this process, the second latching portion 230 undergoes elastic deformation due to external force, and its end away from the first partition portion 220 gradually releases its contact with the end of the first latching portion 120 away from the first body 110. Once the contact is released, the constraint that originally restricted the relative positions of the first partition member 100 and the second partition member 200 in the third direction Z is broken. This disassembly method utilizes the elastic design of the second latching portion 230, making the operation simple and convenient. It also ensures that other components of the partition device are not damaged during disassembly, facilitating subsequent maintenance, component replacement, or rearrangement of the partition device as needed.
[0054] In some embodiments, please refer to Figure 7The angle between the side of the first snap-fit portion 120 facing the first partition portion 220 and the first body 110 is A1, and the minimum angle between the side of the second snap-fit portion 230 facing the second body 210 and the first partition portion 220 is B1, satisfying 0°≤A1-B1≤15°. It should be noted that this angle difference range is set based on considerations of the mechanical characteristics of the snap-fit process and assembly convenience. When the difference between A1 and B1 is within this range, it ensures that the first snap-fit portion 120 and the second snap-fit portion 230 form a smooth contact and deformation path through the inclined surface during the snap-fit process, while avoiding sudden changes in snap-fit force due to excessive angle difference, which could lead to a sudden increase in assembly resistance or damage to components.
[0055] Specifically, when A1-B1 = 0°, the bevel angles of the two locking parts are perfectly matched. During the locking process, the second locking part 230 can fit against the first locking part 120 with minimal deformation, effectively reducing assembly energy consumption and stress concentration caused by excessive deformation, thus improving the long-term stability of the locking structure. As the angle difference gradually increases to 15°, the second locking part 230 will undergo moderate elastic deformation during insertion. This deformation not only helps overcome assembly errors but also forms a tighter engagement after locking, enhancing the device's vibration and impact resistance. During disassembly, the moderate angle difference allows operators to more precisely control the degree and direction of deformation when prying the second locking part 230, avoiding excessive disassembly resistance or component breakage risks caused by unreasonable angle design. By limiting the difference between A1 and B1 to between 0° and 15°, the efficiency and reliability of the partition device during assembly are ensured, while the convenience of disassembly and maintenance is also taken into account, thereby significantly improving the practicality and applicability of the entire device in electrical cabinet application scenarios.
[0056] In some embodiments, please refer to Figure 7 The angle between the side of the first snap-fit portion 120 facing the first partition portion 220 and the first body 110 is A1, and the minimum angle between the side of the second snap-fit portion 230 facing the second body 210 and the first partition portion 220 is B1, satisfying 90°-B1≤A1≤45°. This angular relationship is set based on a comprehensive balance between the mechanical performance of the snap-fit structure and the actual engineering requirements.
[0057] From the perspective of the snap-fit process, when A1 is within this angle range, it ensures that the first snap-fit part 120 and the second snap-fit part 230 form a reasonable contact slope when they cooperate with each other. The lower limit of 90°-B1 ensures that the inclination of the slope is not too large during the initial contact stage of the two snap-fit parts, so that the second snap-fit part 230 can contact the first snap-fit part 120 in a relatively gentle manner and undergo elastic deformation when passing through the first through hole 111, effectively avoiding excessive instantaneous impact force due to excessive angle, which could damage the snap-fit components. The upper limit of 45° provides sufficient inclination for the snap-fit parts, allowing the second snap-fit part 230 to undergo moderate elastic deformation during the snap-fit process. After snapping in place, the elastic restoring force forms abutment, enhancing the stability and vibration resistance of the snap-fit structure.
[0058] In terms of ease of assembly, this angle range effectively reduces assembly difficulty. When assembling the second partition 200 with the first partition 100, the second snap-fit part 230 can be more easily aligned with the first snap-fit part 120 due to the angular fit between A1 and B1, reducing repeated adjustments caused by angular deviations and improving assembly efficiency. At the same time, the reasonable angle setting makes the snap-fit process smoother, requiring no additional auxiliary tools or special operating skills, thus lowering the skill requirements for operators.
[0059] When the partition device needs to be disassembled, the operator can cause it to elastically deform by bending the second locking part 230. Since A1 and B1 satisfy 90°-B1≤A1≤45°, the direction and extent of deformation of the second locking part 230 can be effectively controlled during disassembly. This avoids excessive deformation or stress concentration caused by improper angles, preventing component damage and ensuring the safety and integrity of the partition device during disassembly. It also facilitates subsequent maintenance, component replacement, or rearrangement. Through this angle setting, the partition device exhibits excellent performance in all aspects of assembly, use, and disassembly, greatly improving its practicality and reliability in real-world applications such as electrical cabinets.
[0060] In some embodiments, please refer to Figure 8 The first partition 100 has two first engaging portions 120, and the first body 110 has two first through holes 111 corresponding to the two first engaging portions 120. The second partition 200 has two first dividing portions 220 arranged circumferentially around the second body 210, and each first dividing portion 220 passes through a first through hole 111, so that the second engaging portion 230 on each first dividing portion 220 engages with a first engaging portion 120. This structural design is based on the consideration of improving the overall stability and reliability of the partition device. By using a multi-point engaging method, the external force borne by a single engaging portion is distributed, effectively reducing the risk of engaging failure due to excessive local stress.
[0061] From the assembly process, when assembling the first partition 100 and the second partition 200, the operator can simultaneously align the two first partition portions 220 with their corresponding first through holes 111, and then push the second partition 200 so that the first partition portions 220 pass through the first through holes 111 along the third direction Z. During this process, the second locking portion 230 gradually contacts the first locking portion 120 and deforms until the first body 110 and the second body 210 reach a predetermined distance, at which point the second locking portion 230 returns to its original shape and completes the locking. During the operation of the electrical cabinet, the equipment may experience displacement or stress due to factors such as vibration and thermal expansion and contraction. The double-point locking can more effectively resist these external forces, maintain the stable connection state of the partition device, and thus ensure the reliability of the electrical clearance and improve the safety of the electrical equipment. At the same time, because the two locking parts work together, even if one locking point becomes slightly loose, the other locking point can still maintain basic connection strength, providing redundancy for the safe operation of the equipment.
[0062] In some examples, when the two first snap-fit portions 120 are arranged opposite each other along the first direction X, this layout is more suitable for scenarios where stability requirements in the first direction X are high. For example, in an electrical cabinet, if the equipment is susceptible to significant vibration or external impact in the first direction X, the two snap-fit portions distributed along the first direction X can form a stronger constraint in the first direction X, effectively limiting the relative displacement between the first partition 100 and the second partition 200 in the first direction X, and enhancing the device's impact resistance in the first direction X. Furthermore, since the two snap-fit portions are in the same direction, alignment is easier during assembly, further improving assembly efficiency. This double-snap-fit structure not only simplifies the assembly process but also ensures precise positioning between the two components through symmetrically distributed snap-fit points, reducing the accumulation of assembly errors.
[0063] In some examples, when the two first engaging portions 120 are perpendicular in the first direction X and the second direction Y, this orthogonal distribution provides all-around constraint in the horizontal plane (the plane formed by the first direction X and the second direction Y). In practical applications, it can better cope with external forces from different directions, whether vibrations or displacements along the first direction X or the second direction Y. The vertically distributed engaging portions can effectively limit the relative movement of the two components in the horizontal plane through mutual cooperation. This layout is particularly suitable for electrical cabinets under complex operating conditions, providing a more robust and reliable connection for the isolation device, ensuring the stability of electrical clearances, and thus guaranteeing the safe operation of electrical equipment in variable environments.
[0064] In some embodiments, the first partition 100 has three first snap-fit portions 120, and the first body 110 has three first through holes 111 corresponding to the three first snap-fit portions 120. The second partition 200 has three first partition portions 220 arranged circumferentially around the second body 210, and each first partition portion 220 is respectively inserted into a first through hole 111, so that the second snap-fit portion 230 on each first partition portion 220 is respectively engaged with a first snap-fit portion 120. This three-snap-fit structure design further enhances the connection stability and reliability on the basis of the two-snap-fit structure, and greatly improves the ability of the partition device to cope with complex working conditions.
[0065] From the assembly process perspective, when assembling the first partition 100 and the second partition 200, the operator needs to simultaneously align the three first partition portions 220 with the corresponding three first through holes 111, which ensures more precise positioning between components. When pushing the second partition 200, the three first partition portions 220 simultaneously pass through the first through holes 111 along the third direction Z. During this period, the three second locking portions 230 sequentially contact the corresponding first locking portions 120 and undergo elastic deformation. As the distance between the first body 110 and the second body 210 continuously decreases, the three second locking portions 230 gradually return to their original shape, completing the locking engagement with the first locking portions 120. Although the entire assembly process is relatively complex, the multi-locking point collaborative positioning effectively reduces the errors that may be caused by a single locking portion, ensuring high assembly precision.
[0066] From a mechanical perspective, the three locking joints can evenly distribute external forces from all directions, avoiding localized stress concentration. During the operation of the electrical cabinet, whether it's the periodic external force generated by equipment vibration or the deformation stress caused by thermal expansion and contraction, the three-locking joint structure, with its stable mechanical properties, can evenly transmit these external forces to the entire partition device, effectively reducing the load on individual locking joints and thus improving the overall durability of the device. Furthermore, the redundant connection design provided by the three locking joints further enhances the reliability of the device. Even if one locking joint accidentally loosens or is damaged, the other two locking joints can still maintain a certain connection strength, ensuring that the partition device can continue to perform its isolation function in the event of a fault, thus buying more maintenance time for the safe operation of electrical equipment.
[0067] In some embodiments, please refer to Figure 3 , Figure 4 , Figure 6 , Figure 9The second partition 200 includes at least one positioning part 240, which is circumferentially spaced from the first partition 220 around the second body 210. Correspondingly, the first body 110 has at least one positioning hole 112, which is adapted to each positioning part 240. The first body 110 has at least one positioning hole 112 for the positioning part 240 to pass through. This structural design further optimizes the connection system of the partition device. Through the cooperation of the positioning part 240 and the positioning hole 112, the relative position of the first partition 100 and the second partition 200 is precisely constrained, significantly improving the overall assembly accuracy and structural stability of the device. It should be noted that the total number of the first partition 220 and the positioning part 240 is four. Under the condition of a total of four, the number of the first partition 220 and the positioning part 240 can be arbitrarily designed, and no specific limitation is made here.
[0068] Specifically, the number of positioning parts 240 can be one, two, or three. When there is one positioning part 240, the number of positioning holes 112 on the first body 110 is also one; when there are two positioning parts 240, the number of positioning holes 112 on the first body 110 is also two; when there are three positioning parts 240, the number of positioning holes 112 on the first body 110 is also three.
[0069] In some examples, please refer to Figure 4 , Figure 5 , Figure 6 Taking the case where there are two positioning parts 240 as an example, the two positioning parts 240 are arranged opposite each other on both sides of the second body 210 along the second direction Y. Correspondingly, the two positioning holes 112 on the first body 110 are also arranged opposite each other along the second direction Y. This arrangement can fully utilize the cooperation between the positioning parts 240 and the positioning holes 112, further enhancing the stability of the relative positions of the first partition member 100 and the second partition member 200 in the second direction Y. When the first partition 220 passes through the first through hole 111 to define the relative position in the first direction X, and the first snap-fit part 120 and the second snap-fit part 230 fix the relative position in the third direction Z, the positioning part 240 and the positioning hole 112 closely cooperate in the second direction Y, so that the relative positions of the first partition 100 and the second partition 200 in three mutually perpendicular directions, namely the first direction X, the second direction Y, and the third direction Z, are effectively and stably defined. This ensures the stability and reliability of the entire partition device structure in all aspects, ensuring that it can operate stably in various complex environments and perform its partition function well.
[0070] Furthermore, there is another arrangement for the positioning part 240. One positioning part 240 can be positioned on one side of the second body 210 in the second direction Y, while the other positioning part 240 is positioned opposite the first partition part 220 on both sides of the second body 210. Positioning holes 112 are provided at corresponding positions on the first body 110 to cooperate with the two positioning parts 240. The positioning part 240 positioned on the second body 210 in the second direction Y is mainly responsible for defining the relative position in the second direction Y, ensuring the stability of the positions of the first partition member 100 and the second partition member 200 in that direction. The other positioning part 240, positioned opposite the first partition part 220, cooperates with the first partition part 220 to further enhance the stability of the relative position definition of the first partition member 100 and the second partition member 200 in the first direction X. In other words, in this embodiment, the relative positions of the first partition member 100 and the second partition member 200 in three mutually perpendicular directions—the first direction X, the second direction Y, and the third direction Z—can be more effectively defined. This not only greatly enhances the stability of the entire partition structure, but also ensures that it can continuously and reliably perform its partition function in complex environments, providing a solid guarantee for the safe operation of related equipment.
[0071] In some examples, taking the case where there are three positioning parts 240, two positioning parts 240 are arranged opposite each other on both sides of the second body 210 along the second direction Y, and another positioning part 240 and the first partition 220 are arranged opposite each other on both sides of the second body 210 along the first direction X. That is, the three positioning parts 240 and the first partition 220 are arranged circumferentially around the second body 210. Positioning holes 112 are provided at corresponding positions on the first body 110 to mate with the three positioning parts 240. The two positioning parts 240 arranged opposite each other along the second direction Y mate with their corresponding positioning holes 112 to define the positions of the first partition 100 and the second partition 200 in the second direction Y. The positioning part 240, which is opposite to the first partition 220 in the first direction X, mates with one positioning hole 112 and then with the first partition 220, further enhancing the stability of the relative position definition of the first partition 100 and the second partition 200 in the first direction X. In other words, the relative positions of the first partition 100 and the second partition 200 in three mutually perpendicular directions—namely, the first direction X, the second direction Y, and the third direction Z—are more effectively defined in this embodiment. This not only greatly improves the stability of the entire partition device structure but also ensures that it can continuously and reliably perform its partitioning function in complex environments, providing a solid guarantee for the safe operation of related equipment.
[0072] It should be noted that, from a working principle perspective, the engagement between the positioning part 240 and the positioning hole 112 is similar to a pin positioning mechanism in a mechanical structure. During assembly, when the first partition 220 passes through the first through hole 111, the positioning part 240 simultaneously aligns with the positioning hole 112. The positioning part 240 is typically designed with a specific shape (such as cylindrical, prism, or plate-like) to form a tight clearance fit with the positioning hole 112. As the second partition 200 approaches the first partition 100, the positioning part 240 gradually inserts into the positioning hole 112. Its precise geometry and dimensions ensure that the relative positions of the two components in the horizontal direction (first direction X and second direction Y) are fixed, effectively preventing offset or misalignment between components. In actual assembly, the circumferentially spaced design of the positioning part 240 and the first partition 220 provides clearer operational guidance for the operator during assembly. The combination of multiple positioning parts 240 and positioning holes 112 acts like multiple positioning anchor points, further enhancing the fault tolerance of the assembly. Even with slight deviations during operation, these positioning structures can guide the first partition 100 and the second partition 200 to accurately engage through their guiding function. For example, when the positioning part 240 is cylindrical, its smooth cylindrical surface can correct the horizontal offset of the component through its own geometry during insertion into the positioning hole 112, ensuring accurate engagement of the locking part. From a technical perspective, the arrangement of the positioning part 240 and the positioning hole 112 brings multiple advantages. First, it improves assembly efficiency. Compared to relying solely on the locking part for positioning, this positioning structure helps workers quickly determine the installation position of the component, reducing the time spent on repeated adjustments. Second, it enhances structural stability. The cooperation between the positioning part 240 and the positioning hole 112 adds extra reinforcement to the locking structure, effectively resisting component loosening caused by vibration, external impact, etc., during the operation of the electrical cabinet, further dispersing the stress borne by the entire partition device. Third, it improves product consistency and reliability.
[0073] In some embodiments, please refer to Figure 11 The first partition 100 has four first snap-fit portions 120, and the first body 110 has four first through holes 111 corresponding to the four first snap-fit portions 120. The second partition 200 has four first partition portions 220 arranged circumferentially around the second body 210, and each first partition portion 220 passes through a first through hole 111 so that the second snap-fit portion 230 on each first partition portion 220 engages with a first snap-fit portion 120. This four-snap-fit structure design is based on the ultimate pursuit of connection strength, stability and reliability of the partition device. By constructing a quadrilateral mechanical framework, a stable connection between components in all directions and multiple dimensions is achieved.
[0074] From the assembly process perspective, when assembling the first partition 100 and the second partition 200, the operator needs to align the four first partition portions 220 with the corresponding four first through holes 111. During the pushing of the second partition 200, the four first partition portions 220 simultaneously penetrate the first through holes 111 along the third direction Z, and the four second locking portions 230 sequentially contact the corresponding first locking portions 120. Since the locking portions are typically designed with an elastic structure, at the moment of contact, the second locking portions 230 will undergo elastic deformation due to force. As the distance between the first body 110 and the second body 210 continuously decreases, the four second locking portions 230 gradually return to their original shape, completing a tight locking fit with the first locking portions 120. In this process, the four locking portions cooperate with each other, ensuring precise alignment of the two components during assembly and reducing assembly errors caused by uneven force on individual locking portions.
[0075] From a mechanical performance perspective, the four-clamp joint structure has significant advantages. The four clamping parts, arranged in a quadrilateral pattern on a plane, can evenly distribute external forces from all directions throughout the partition device. During actual operation of the electrical cabinet, whether subjected to horizontal vibration, vertical impact, or thermal stress caused by temperature changes, the four-clamp joint structure, with its symmetrical mechanical properties, effectively suppresses relative displacement between components. Compared to double-clamp or triple-clamp joint structures, the four-clamp joint structure is particularly outstanding in resisting torsional forces. For example, when the electrical cabinet experiences torsional vibration due to equipment operation, the quadrilaterally distributed clamping parts can mutually restrain each other, decomposing the torsional force into multiple components through the principle of force balance. This prevents components from loosening or being damaged due to excessive localized stress, greatly enhancing the partition device's resistance to deformation.
[0076] In some embodiments, please refer to Figure 12 The partition device comprises multiple first partition components 100 and multiple second partition components 200. The multiple first partition components 100 are arranged sequentially along a first direction X or a second direction Y, and each first partition component 100 is engaged with a second partition component 200. This multi-component combination design is intended to meet the requirements of complex electrical layouts within electrical cabinets and higher electrical safety standards. Through modular arrangement and combination, it achieves precise isolation and protection of electrical components in different areas, significantly improving the overall safety and reliability of the electrical system.
[0077] From an assembly perspective, during installation, workers can arrange multiple first partition components 100 sequentially in a predetermined direction (first direction X or second direction Y) according to the design drawings inside the electrical cabinet. Since each first partition component 100 has a pre-set snap-fit structure, after arrangement, the corresponding second partition components 200 can be quickly snapped into place with the first partition component 100. Taking the arrangement along the first direction X as an example, the operator can first fix the first first partition component 100 in the designated position, then install the corresponding second partition component 200 in place using the snap-fit mechanism, and then install the subsequent first partition components 100 and second partition components 200 in sequence. The entire process is like building with blocks, possessing strong operability and continuity. This modular assembly method not only reduces installation difficulty but also significantly improves assembly efficiency, making it particularly suitable for large-scale production scenarios.
[0078] From a structural advantage perspective, multi-part partition devices offer significant flexibility and adaptability. By adjusting the number and arrangement of the first partition 100 and the second partition 200, they can easily adapt to electrical cabinet spaces of different sizes and shapes. For example, in a long and narrow electrical cabinet, more partitions can be arranged along the first direction X to effectively isolate the elongated area; while in a square or wide electrical cabinet, arranging them along the second direction Y better utilizes space and meets different layout requirements. Furthermore, the independent snap-fit design of each first partition 100 and second partition 200 gives the entire partition device excellent expandability. When new electrical components need to be added to the electrical cabinet or wiring needs to be modified, only new partition combinations need to be added at the corresponding locations, without requiring large-scale modifications to the original structure, effectively reducing the cost of equipment upgrades and maintenance.
[0079] In some embodiments, please refer to Figure 7The angle A1 between the side of the first latching portion 120 facing the first partition portion 220 and the first body 110 satisfies 45°≤A1≤60°. It can be understood that A1 can be any value or a range between any two values from 45°, 46°, 47°, 48°, 49°, 50°, 51°, 52°, 53°, 54°, 55°, 56°, 57°, 58°, 59°, and 60°. It should be noted that this angle range is perfectly suited to the mechanical requirements and assembly process requirements of the latching structure in electrical cabinet applications. When A1 is in the 45°-60° range, the inclined side of the first latching portion 120 can form an ideal contact guide surface with the second latching portion 230. During assembly, this angle ensures that when the second locking part 230 inserts into the first through hole 111, it contacts the first locking part 120 at a relatively gentle angle, avoiding excessive locking resistance due to an excessively small angle, while also ensuring sufficient tilt to allow the second locking part 230 to undergo moderate elastic deformation, ensuring a tight mechanical engagement after locking. From a mechanical perspective, within this angle range, the stress distribution of the locking part under external force is more uniform, effectively dispersing the stress generated by vibration and thermal expansion and contraction during the operation of the electrical cabinet, preventing local stress concentration that could lead to locking failure. For example, in high-temperature environments, when internal components of the electrical cabinet undergo thermal expansion, a suitable A1 angle allows the locking part to maintain a stable connection during deformation, preventing loosening due to an unreasonable angle, thus providing a reliable defense for the safe operation of electrical equipment.
[0080] In some embodiments, please refer to Figure 7The minimum included angle B1 between the side of the second latching portion 230 facing the second body 210 and the first partition portion 220 satisfies 30°≤B1≤45°. It can be understood that B1 can be any value or a range between any two values from 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, and 45°. It should be noted that this angle range setting, in conjunction with the angle A1 of the first latching portion 120, jointly constructs an efficient and stable latching system. The lower limit of angle B1 at 30° ensures that the second locking part 230 has sufficient rigid support, preventing excessive deformation under external pressure and maintaining the basic shape of the locking structure. The upper limit of 45° gives the second locking part 230 good elastic deformation capability, allowing it to cleverly avoid obstacles caused by assembly errors during engagement with the first locking part 120, achieving smooth engagement. During disassembly, this angle range allows operators to apply appropriate force and direction to pry the second locking part 230 away from the first locking part 120, ensuring ease of disassembly while avoiding damage to components due to improper angle. For example, in electrical cabinet maintenance scenarios, technicians can easily disassemble and repair the partition device. Thanks to the design advantages of angle B1, equipment maintenance efficiency is significantly improved while reducing maintenance costs.
