New power filter

Abstract

This utility model relates to a novel power filter. By arranging multiple output terminals longitudinally in layers at the highest and secondary mounting positions along the insulating base, it replaces the existing method of arranging output terminals laterally at intervals. This significantly reduces the lateral space occupied by the new power filter, making it suitable for installation in narrow spaces such as data center chassis and solving the problem of poor adaptability to confined spaces. Simultaneously, by providing a mounting groove formed by a lower support plate and an upper protective plate, and ensuring that the longitudinal projection of any wire connection hole of the upper output terminal partially or completely overlaps with the longitudinal projection of the lower upper protective plate, without any intersection between the longitudinal projections of any two wire connection holes, the wire connection holes on each output terminal are fully exposed and do not obstruct each other even with a compact longitudinal arrangement. This reduces the lateral dimensions while facilitating the installation of wire connection bolts.

Description

Technical Field

[0001] This utility model relates to the field of filters, and in particular to a novel power supply filter. Background Technology

[0002] A power filter is a passive / active device used to suppress electromagnetic interference signals conducted along power lines. It is typically connected in series between the power input and the load, effectively filtering out common-mode and differential-mode interference in the power supply, providing a cleaner power supply to downstream equipment, thus ensuring stable operation of electronic equipment and meeting relevant electromagnetic compatibility requirements. However, existing power filters still have certain shortcomings: Existing power filters often employ a horizontally spaced arrangement of their multiple output terminals. This arrangement aims to fully expose all the wiring terminals on each output terminal, facilitating cable connection and securing. However, this horizontally arranged and spaced layout significantly increases the overall lateral space occupied by the filter. While facilitating wiring, it sacrifices the compactness of the product structure, making the filter difficult to install in environments with extremely limited internal space, such as data center chassis, and exhibiting poor adaptability to confined spaces.

[0003] In particular, with the diversification of power demand, when the filter needs to meet the requirements of three-phase four-wire power supply and each output terminal needs to be configured with multiple terminals to cope with the needs of multiple cable connections, four output terminals must be set. However, the addition of terminals to each terminal will further increase its own lateral size. As a result, four output terminals at the same height and arranged at intervals will drastically increase the overall lateral space required by the product, making the compactness very low. This seriously restricts the normal deployment of the filter in a small space and brings layout difficulties or even the inability to install it in high-density installation scenarios such as data center cabinets.

[0024] The following are the beneficial effects of implementing this utility model: This utility model relates to a novel power filter, which replaces the existing technology of arranging output terminals horizontally at intervals by layering multiple output terminals along the longitudinal direction of the insulating base at the highest mounting position and each secondary mounting position. This significantly reduces the horizontal space occupied by the new power filter, enabling it to adapt to the installation requirements in narrow spaces such as data center chassis, and solving the problem of poor adaptability of products in narrow spaces.

[0025] Meanwhile, by setting the secondary mounting position as a mounting groove formed by the lower support plate and the upper protective plate, and by making the longitudinal projection of any wire connection hole of the upper output terminal of any two adjacent output terminals partially or completely overlap with the longitudinal projection of the lower upper protective plate, and ensuring that the longitudinal projections of any two wire connection holes do not intersect, the wire connection holes on each output terminal can still be fully exposed and not obstruct each other under the compact longitudinal arrangement. This reduces the lateral size while making it convenient for operators to complete cable connections using wire connection bolts, thus ensuring wiring convenience. Attached Figure Description

[0032] Figure 1 and Figure 2 The illustration shows a novel power filter 10 according to some embodiments of the present invention, which includes a filter housing 1, an insulating base 2, and an output device 3. The insulating base 2 is disposed on the filter housing 1, and the output device 3 is disposed on the insulating base 2.

[0033] It should be noted that the filter housing 1 provides mounting positions for the various components required by the filter and supports the insulating base 2. The output device 3 is used for electrical connection with the electrical equipment, transmitting the filtered current to the subsequent electrical equipment.

[0034] like Figures 1 to 10 As shown, the insulating base 2 is disposed on the periphery of the filter housing 1. The insulating base 2 is provided with a highest mounting position 21 and multiple secondary mounting positions 22. The highest mounting position 21 and each secondary mounting position 22 are arranged at intervals along the longitudinal direction, and each secondary mounting position 22 is located below the highest mounting position 21. The highest mounting position 21 is provided with a highest insertion hole 211. Each secondary mounting position 22 is provided with a lower support plate 221 and an upper protective plate 222 arranged at intervals. A mounting groove 223 is formed between the lower support plate 221 and the upper protective plate 222.

[0035] The output device 3 includes multiple output terminals 31, one of which is inserted into the highest insertion hole 211, and the remaining output terminals 31 are inserted into each mounting slot 223 respectively. Each output terminal 31 has multiple wire connection holes 3111 on the part exposed outside the insulating base 2. Each wire connection hole 3111 is for wire connection bolts 32 to pass through and screw.

[0036] Please refer to Figure 10 In the longitudinal direction of the insulating base 2, the projections of any two wire connection holes 3111 do not intersect.

[0037] Please refer to Figure 10 Between any two adjacent output terminals 31, the longitudinal projection S1 of any wire connection hole 3111 in the upper output terminal 31 partially or completely overlaps with the longitudinal projection S2 of the lower upper protective plate 222.

[0038] Understandably, the insulating base 2 is made of insulating material to achieve electrical isolation between the output device 3 and the filter housing 1. Furthermore, the insulating base 2, through its longitudinal extension structure, provides a basis for the layered arrangement of each output terminal 31, transforming the lateral space occupied by multiple output terminals 31 into a longitudinal arrangement, thus reducing the lateral dimensions of the novel power filter 10. The highest mounting position 21 is used to install the uppermost output terminal 31, defining the highest position of this output terminal 31 in the longitudinal direction of the insulating base 2. Each secondary mounting position 22 is used to install the remaining output terminals 31 one by one. By being longitudinally spaced from the highest mounting position 21, the output terminals 31 are arranged in a layered manner along the longitudinal direction of the insulating base 2. The contour of the highest insertion hole 211 matches the outer contour of the output terminal 31 with the highest longitudinal position, thereby ensuring stable and reliable support for this highest longitudinally positioned output terminal 31.

[0039] Regarding the lower support plate 221 and upper protective plate 222 that are spaced vertically within each secondary mounting position 22, the lower support plate 221 defines the lower boundary of the mounting groove 223, and the upper protective plate 222 defines the upper boundary of the mounting groove 223. Specifically, the lower support plate 221 is used to support the output terminal 31 inserted into the secondary mounting position 22, and the upper protective plate 222 is used to limit the output terminal 31 from the opposite side, and also to form a separation and protection between adjacent output terminals 31. Furthermore, and especially importantly, the upper surface of each upper protective plate 222 partially or completely overlaps with the projection of the wire connection hole 3111 of the output terminal 31 located above it in the longitudinal direction, thereby providing necessary electrical isolation with a compact longitudinal spacing, without obstructing the operation of the wire connection hole 3111.

[0040] Relative to the output device 3, each output terminal 31 is used to conduct filtered current. The portion of the terminal inserted and exposed outside the mounting slot 223 or the highest insertion hole 211 provides operating space for wire connection. Wire connection holes 3111 are used for wire connection bolts 32 to pass through, clamping and fixing external wires to the output terminal 31. Furthermore, it is particularly important to note that since the projections of any two wire connection holes 3111 in the longitudinal direction of the insulating base 2 are configured to not intersect, the wire connection holes 3111 are arranged compactly without vertical interference, ensuring that operating tools can be easily inserted. For example, the operator can directly place the bolt locking sleeve onto the wire connection bolt 32 on the output terminal 31 to be locked from the longitudinal direction, avoiding interference from the protrusion of other conductive terminals. The wire connection bolt 32 is used to achieve a reliable electrical connection between the wire and the output terminal 31.

[0041] Regarding the upper protective plate 222, it should be noted that because "the upper surface of the upper protective plate 222 partially or completely overlaps with the projection of the wire connection hole 3111 of the output terminal 31 located above in the longitudinal direction," it can prevent the wire connection bolt 32 from excessively rotating and directly contacting the output terminal below when the worker inserts the wire connection bolt 32 through the wire connection hole 3111 from top to bottom and screws it in. Specifically, in actual working conditions, construction personnel may make human error—using a bolt of mismatched length to thread into the wire connection hole 3111. This can cause the end of the excessively long bolt to contact the output terminal 31 below and conduct electricity before the bolt is fully tightened and locked into the corresponding wire connection hole 3111, leading to a short circuit. In applications such as data centers where power stability is extremely important, this can easily lead to very serious consequences, such as burnt-out components or even data loss. By employing the positional relationship between the upper protective plate 222 and the wire connection hole 3111 of the upper output terminal 31 as described in this utility model, even if an operator mistakenly uses a bolt of a different specification to electrically connect the external wire to the output terminal 31, the excessively long bolt end will only rest against the lower upper protective plate, preventing the bolt from directly contacting and conducting the two output terminals 31. This greatly reduces the risk of human error. For manufacturers, this also avoids the problem of untraceable human error leading to a sharp increase in after-sales maintenance costs.

[0042] In summary, this utility model arranges multiple output terminals 31 in a longitudinal layered manner by the highest mounting position 21 and multiple secondary mounting positions 22 on the insulating base 2, replacing the transversely spaced arrangement. This significantly reduces the transverse space occupied by the new power filter, making it suitable for narrow installation environments. Simultaneously, the projection configuration of the upper protective plate 222 in the secondary mounting position 22 and the wire connection hole 3111 on the upper output terminal 31 overlaps, and the longitudinal projection configuration of each wire connection hole 3111 is non-intersecting. This ensures that each wire connection hole 3111 is fully exposed and does not obstruct the operation and locking space of each other under the longitudinal arrangement, balancing wiring convenience and operational safety.

[0043] like Figure 8 As shown, in some embodiments of the novel power filter 10, the upper protective plates 222 are parallel to each other, and the central axis L1 of any wire connection hole 3111 is perpendicular to the upper surface α of the upper protective plate 222, so that the central axis of any wire connection bolt 32 in the length extension direction is perpendicular to the upper surface α of the upper protective plate 222.

[0044] Understandably, in this embodiment, each upper protective plate 222 is configured to be parallel to each other, thereby forming a consistent isolation surface (i.e., the upper surface of each upper protective plate 222) in the longitudinal distribution structure of the secondary mounting position 22, making the protective structure neat, facilitating overall molding and assembly, and providing a uniform working orientation reference for the wire connection bolt 32.

[0045] Furthermore, in this embodiment, the central axis L1 of the wire connection hole 3111 is configured to be perpendicular to the upper surface α of the upper protective plate 222, so that after the wire connection bolt 32 is inserted into the wire connection hole 3111, its central axis in the length extension direction is also perpendicular to the upper surface α. This ensures that the screwing operation direction of the wire connection bolts 32 on all output terminals 31 is consistent, eliminating the need for operators to repeatedly adjust tool posture during wire connection, thus significantly improving the convenience and efficiency of wiring in confined operating spaces. Of course, it also ensures that each wire connection bolt 32 moves as linearly as possible in the longitudinal direction, preventing the ends of the wire connection bolts 32 from tilting and avoiding the upper protective plate below, thus ensuring the effectiveness of insulation isolation.

[0046] like Figures 5 to 9 As shown, in some embodiments of the novel power filter 10, the insulating base 2 is provided with a highest mounting position 21 and two secondary mounting positions 22, and the highest mounting position 21 and the two secondary mounting positions 22 are arranged alternately along the longitudinal direction.

[0047] Understandably, in this embodiment, the total number of output terminals 31 is three, thus enabling the product to adapt to three-phase three-wire wiring requirements. Furthermore, the number of wire connection holes 3111 on each output terminal 31 can be flexibly set.

[0048] In some embodiments of the novel power filter 10, the insulating base 2 is provided with a highest mounting position 21 and three secondary mounting positions 22, and the highest mounting position 21 and the three secondary mounting positions 22 are arranged alternately along the longitudinal direction.

[0049] Understandably, in this embodiment, there are a total of four output terminals 31, and the insulating base 2 presents a four-layer wiring structure distributed longitudinally. Thus, the product can adapt to the wiring requirements of three-phase four-wire systems. Furthermore, the number of wire connection holes 3111 on each output terminal 31 can be flexibly set.

[0050] like Figure 5 As shown, in some embodiments of the novel power filter 10, an external connection surface 23 is provided on the insulating base 2, and the highest mounting position 21 and each secondary mounting position 22 are located on the external connection surface 23.

[0051] Please refer to the following: Figures 5 to 10 A maximum support plate 212 is provided in the highest mounting position 21, which is used to contact the lower surface of the output terminal.

[0052] Among them, the highest support plate 212 has a first protrusion T1 relative to the outer connecting surface 23, each lower support plate 221 has a second protrusion T2 relative to the outer connecting surface 23, and each upper protective plate 222 has a third protrusion T3 relative to the outer connecting surface 23.

[0053] Understandably, the outer connecting surface 23 serves as the mounting surface on the insulating base 2 for arranging the output terminals 31, providing a unified longitudinal positioning reference for the highest mounting position 21 and each secondary mounting position 22, thus ensuring the accuracy and consistency of the relative positions of each output terminal 31 after installation. The highest support plate 212 is used to provide support and limit the output terminals 31 located in the highest mounting position 21 in the longitudinal direction.

[0054] like Figure 7 As shown, in some embodiments of the novel power filter 10, the first protrusion T1 is smaller than any second protrusion T2, and in the direction of increasing height of the insulating base 2, each second protrusion T2 gradually decreases, and each third protrusion T3 gradually decreases.

[0055] Understandably, configuring the first protrusion T1 to be less than any second protrusion T2 makes the protrusion of the output terminal 31 at the highest mounting position 21 less than the protrusion of the output terminal 31 at each of the secondary mounting positions 22. That is, the wire connection hole 3111 on the output terminal 31 at the highest mounting position 21 is located closer to the outer connection surface 23 in the longitudinal direction, making more space available for the wiring operation of the output terminals 31 in the lower layers.

[0056] Furthermore, in this embodiment, in the direction of increasing height of the insulating base 2, the second protrusion T2 is further configured to gradually decrease, thereby making the protrusion of the output terminal 31 relative to the external connection surface 23 larger in the lower secondary mounting position 22. Thus, when comparing any two output terminals 31, the protrusion of the output terminal 31 with a higher position on the insulating base 2 relative to the external connection surface 23 is smaller than the protrusion of the output terminal 31 with a lower position relative to the external connection surface 23. Therefore, output terminals at different heights will not obstruct or interfere with the wire connection holes 3111 of output terminals at other positions.

[0057] Furthermore, in the direction of increasing height of the insulating base 2, the amount of each third protrusion T3 gradually decreases. This can, on the one hand, prevent the upper protective plate 222 in the same secondary mounting position 22 from obstructing the wire connection hole 3111 on the output terminal 31, and on the other hand, ensure that the upper protective plate 222 can limit the insertion depth of the upper wire connection bolt 32, that is, prevent the end of the upper wire connection bolt 32 from abutting against the output terminal 31 in the current secondary mounting position 22.

[0058] It should be noted that the progressively decreasing protrusion in this embodiment ensures that the wire connection holes 3111 of each layer of output terminals 31 are staggered longitudinally, further guaranteeing that the longitudinal projections of each wire connection hole 3111 do not obstruct each other. Furthermore, it ensures that the projection overlap between the upper wire connection hole 3111 and the lower upper protective plate 222 of any adjacent output terminals 31 is stably and reliably determined at each level.

[0059] like Figure 7 As shown, in some embodiments of the novel power filter 10, in any secondary mounting position 22, the third protrusion T3 of the upper protective plate 222 is less than the second protrusion T2 of the lower support plate 221, and the difference between the second protrusion T2 and the third protrusion T3 is 3mm to 5mm.

[0060] Understandably, by adopting the content of this embodiment, the lateral extension length of the upper protective plate 222 in the same secondary mounting position 22 is shorter than the lateral extension length of the output terminal 31 in the same secondary mounting position 22. By limiting this difference to 3mm~5mm, the lateral exposure of the area where the wire connection hole 3111 on the output terminal 31 is located in the same mounting groove 223 beyond the top of the upper protective plate 222 can be limited. This ensures that when the wire connection bolt 32 is inserted into the wire connection hole 3111, the bolt head and the operating tool's movement space completely avoid the upper protective plate 222, preventing the bolt head from interfering with the upper protective plate 222 during the tightening process. At the same time, it ensures that the exposure is not too large, which would lead to an unnecessary increase in lateral dimensions, thus ensuring the overall compactness of the product.

[0061] like Figure 7 As shown, in some embodiments of the novel power filter 10, the size of the first protrusion T1 is 3mm to 5mm.

[0062] Understandably, by setting the first protrusion T1 to 3mm~5mm, it can be ensured that the wire connection hole 3111 on the output terminal 31 at the highest mounting position 21 has sufficient lateral exposed space, so as to prevent the wire connection bolt 32 from being blocked by the outer connection surface 23 during insertion and tightening.

[0063] like Figures 1 to 7 As shown, in some embodiments of the novel power filter 10, the filter housing 1 includes a bottom shell 11 and a cover 12. A U-shaped mounting notch 111 is provided on the bottom shell 11, and a U-shaped mounting ring groove 24 is provided on the insulating base 2 (the U-shaped mounting ring groove 24 is found in...). Figure 5 and Figure 6 The insulating seat 2 is inserted into the U-shaped mounting notch 111, and the side wall of the U-shaped mounting notch 111 is inserted into the U-shaped assembly ring groove 24. The cover 12 is placed on the bottom shell 11 and abuts against the insulating seat 2.

[0064] Understandably, the bottom shell 11 and the cover 12 are used together to accommodate the various components required for the filter. The U-shaped mounting notch 111 provides an insertion position for the insulating base 2. The cover 12 is used to limit the insulating base 2 in the longitudinal direction, preventing the insulating base 2 from coming out of the U-shaped mounting notch 111. The U-shaped mounting ring groove 24 is used to accommodate the side wall of the U-shaped mounting notch 111, so that the insulating base 2 and the bottom shell 11 form a mutually fitting structure through the plug-in fit, realizing the positioning and fixation of the insulating base 2 on the bottom shell 11, limiting the lateral movement and longitudinal displacement of the insulating base 2 relative to the bottom shell 11, ensuring the stability of the assembly between the output device 3 and the filter housing 1, and improving the positional stability of the output device 3.

[0065] like Figure 6As shown, in some embodiments of the novel power filter 10, the bottom of the insulating base 2 is provided with a glue-reducing groove 25, and a plurality of reinforcing ribs 251 are provided in the glue-reducing groove 25, and the reinforcing ribs 251 are cross-connected.

[0066] Understandably, the material reduction groove 25 is used to reduce the amount of material used during the molding of the insulating base 2, thereby reducing manufacturing costs and weight. Each reinforcing rib 251 forms a mesh-like reinforcing structure in the area thinned by the material reduction groove 25, improving the structural rigidity and deformation resistance of the bottom of the insulating base 2. This prevents insufficient strength of the insulating base 2 due to the material reduction groove 25, ensuring structural stability of the insulating base 2 when subjected to the insertion force of the output terminal 31 and the tightening force of the wire connection bolt 32. Thus, this embodiment, by setting the material reduction groove 25 and the cross-connected reinforcing ribs 251, reduces the weight of the insulating base 2 and lowers material costs while ensuring its structural strength meets usage requirements.

[0067] like Figure 9 and Figure 10 As shown, in some embodiments of the novel power filter 10, each mounting slot 223 is provided with a limiting part 224, which abuts against the output terminal 31.

[0068] Understandably, the limiting part 224 is used to limit the position of the output terminal 31 after it is inserted into the mounting slot 223, preventing the output terminal 31 from being over-inserted or from being accidentally displaced during use. In this way, on the one hand, the positional assembly accuracy of each output terminal 31 can be improved during assembly, and on the other hand, the positional stability of the output terminal 31 can be improved during use.

[0069] like Figures 8 to 10 As shown, in some embodiments of the novel power filter 10, each output terminal 31 includes an external portion 311, a connecting portion 312, and an internal portion 313 connected in sequence. Each wire connection hole 3111 is located on the external portion 311. A portion of the external portion 311 is inserted into the mounting groove 223 and abuts against the limiting portion 224. The connecting portion 312 passes through the insulating seat 2. The internal portion 313 is exposed inside the filter housing 1. The amount of protrusion of each internal portion 313 inside the filter housing 1 is equal, and each internal portion 313 has an internal wiring hole 3131 in the portion exposed inside the filter housing 1.

[0070] Understandably, the external portion 311 is the part of the output terminal exposed outside the insulating base 2, used to connect external wires via the wire connecting bolt 32 to realize the external output of filtered current. When inserting the output terminal 31, the insertion depth of the output terminal 31 can be quickly positioned by the abutment of the external portion 311 and the limiting portion 224. The connecting portion 312 is used to realize the electrical connection between the external portion 311 and the internal portion 313, leading the filtered current from inside the filter housing 1 to the external portion 311. The internal portion 313 is used to realize the electrical connection with the circuit components inside the filter housing 1 and receive the filtered current. Furthermore, by configuring the protrusion of each internal portion 313 inside the filter housing 1 to be equal, the internal portion 313 of each output terminal 31 can have a uniform protrusion inside the filter housing 1, thereby simplifying the internal wiring assembly process and ensuring the consistency of internal wiring.

[0071] In addition, the inner wiring hole 3131 is used for the internal wiring bolts to pass through, pressing and fixing the wires or conductive parts inside the filter housing 1 onto the inner connection part 313, so as to realize the electrical connection between the inner connection part 313 and the internal circuit of the filter.

[0072] like Figure 8 and Figure 9 As shown, in some embodiments of the novel power filter 10, the length of each connecting portion 312 decreases sequentially in the direction of increasing height of the insulating base 2.

[0073] Understandably, by adopting the content of this type of embodiment, although the inner connection portion 313 of each output terminal protrudes equally within the filter housing 1, the longitudinal height position of the outer connection portion 311 outside the insulating base 2 adapts layer by layer with the change in the length of the connection portion 312. In conjunction with the longitudinal layered arrangement of each output terminal 31 on the insulating base 2, the wire connection holes 3111 of the outer connection portion 311 are staggered in the longitudinal direction, and the longitudinal projections of the wire connection holes 3111 of each layer do not obstruct each other.

[0074] like Figure 8 and Figure 9 As shown, in some embodiments of the novel power filter 10, the external portion 311, the connecting portion 312, and the internal portion 313 in each output terminal are configured as an integrally formed structure.

[0075] Understandably, by employing the methods described in this embodiment, all positions of the output terminal can be tightly fitted, thereby reducing contact resistance, improving conductivity reliability, and enhancing the structural integrity and bending strength of the terminal block. This prevents deformation or breakage due to torque during the tightening of the wire connection bolts 32. Thus, to a certain extent, the product's durability and conductivity reliability are improved.

[0076] like Figures 6 to 9As shown, in some embodiments of the novel power filter 10, the output device 3 further includes a plurality of external nuts 33 and a plurality of internal nuts 34. Each external nut 33 is disposed on the lower surface of each external portion 311, and each external nut 33 is aligned and connected to each wire connection hole 3111. The external nuts 33 are used to be screwed with the wire connection bolts 32. Each internal nut 34 is disposed on the lower surface of each internal portion 313, and the internal nut 34 is aligned and connected to the internal wiring hole 3131.

[0077] Understandably, each external nut 33 is used to screw into the wire connection bolt 32, providing a threaded fit so that the wire connection bolt 32 can be reliably locked after passing through the wire connection hole 3111, pressing and fixing the external wire onto the external part 311. Similarly, the internal nut 34 ensures that the internal wiring bolt can stably and reliably hold and fix the cable end onto the internal part 313, forming a stable and reliable electrical connection.

[0078] It should be noted that, in this type of embodiment, by setting an external nut 33 and an internal nut 34, a reliable threaded locking structure is provided for the wire connection bolt 32 and the internal wiring bolt, ensuring the firmness of the connection between the external wiring and the internal wiring.

[0079] like Figures 8 to 10 As shown, in some embodiments of the novel power filter 10, each output terminal 31 is provided with three wire connection holes 3111, and the wire connection holes 3111 are arranged one at a time along a straight line, and the center distance between two adjacent wire connection holes 3111 is 15mm~25mm.

[0080] Understandably, the arrangement of three wire connection holes 3111 allows a single output terminal 31 to connect three external wires simultaneously, meeting the wiring requirements for multi-line output. The center distance between two adjacent wire connection holes 3111 is set to 15mm~25mm, providing sufficient clearance for the bolt heads of adjacent wire connection bolts 32 and operating tools, avoiding interference during tightening, and keeping the lateral dimension of the output terminal 31 within a reasonable range to prevent a single output terminal 31 from occupying too much space.

[0081] It should be noted that in this type of embodiment, by setting three wire connection holes 3111 arranged in a straight line with a reasonable center distance, the wiring capacity of a single output terminal 31 is increased and the convenience of wiring operation is ensured.

[0082] In some embodiments of the novel power filter 10, each output terminal 31 is provided with four wire connection holes 3111, and the wire connection holes 3111 are arranged one at a time along a straight line, and the center distance between two adjacent wire connection holes 3111 is 15mm~25mm.

[0083] Understandably, the four wire connection holes 3111 further increase the number of wires that can be connected to a single output terminal 31, adapting to wiring scenarios with more wires. Furthermore, by configuring the wire connection holes 3111 to be spaced apart along a straight line, with an adjacent center-to-center distance of 15mm to 25mm, the wire connection bolts 32 maintain a non-interfering operating distance even with an increased number of connection holes, ensuring that wiring convenience is not affected.

[0084] It should be noted that in this type of embodiment, by setting four wire connection holes 3111, the wiring density of the output terminal 31 is increased, while maintaining the wiring operation space.

[0085] like Figure 3 and Figure 4 As shown, in some embodiments of the novel power filter 10, the bottom edge of the filter housing 1 extends laterally to form a mounting skirt 13, and a through hole 131 is provided on the mounting skirt 13 for mounting bolts to pass through and fix.

[0086] Understandably, the mounting skirt 13 provides a mounting and fixing structure for the entire filter unit. Through holes 131 allow mounting bolts to pass through, securing the new power filter 10 to the preset mounting position. This enables rapid fixing of the new power filter 10, facilitating quick installation of the entire unit inside data center cabinets or other mounting platforms.

[0087] like Figures 1 to 4 As shown, in some embodiments of the novel power filter 10, the novel power filter 10 further includes an input device 4. The input device 4 includes an input socket 41 and a plurality of input terminals 42. The input socket 41 and the insulating base 2 are respectively disposed on two surfaces of the filter housing 1. Each input terminal 42 is disposed on the input socket 41 at intervals along a straight line. Parts of each input terminal 42 pass through the input socket 41 and are exposed inside the filter housing 1. Each input terminal 42 corresponds to each output terminal 31.

[0088] Understandably, the input device 4 is used to receive the external current to be filtered. The input socket 41 provides a mounting position for the input terminals 42, thereby fixing the relative position of each input terminal 42 with respect to the filter housing 1. Furthermore, by separating the input socket 41 and the insulating socket 2 on two different surfaces of the filter housing 1, the current input side and the current output side of the product can be spatially separated, facilitating the identification, routing, and management of external cables, and improving the wiring convenience of the product.

[0089] The following are the beneficial effects of implementing this utility model: This utility model relates to a novel power filter, which replaces the existing technology of arranging output terminals horizontally at intervals by layering multiple output terminals along the longitudinal direction of the insulating base at the highest mounting position and each secondary mounting position. This significantly reduces the horizontal space occupied by the new power filter, enabling it to adapt to the installation requirements in narrow spaces such as data center chassis, and solving the problem of poor adaptability of products in narrow spaces.

[0090] Meanwhile, by setting the secondary mounting position as a mounting groove formed by the lower support plate and the upper protective plate, and by making the longitudinal projection of any wire connection hole of the upper output terminal of any two adjacent output terminals partially or completely overlap with the longitudinal projection of the lower upper protective plate, and ensuring that the longitudinal projections of any two wire connection holes do not intersect, the wire connection holes on each output terminal can still be fully exposed and not obstruct each other under the compact longitudinal arrangement. This reduces the lateral size while making it convenient for operators to complete cable connections using wire connection bolts, thus ensuring wiring convenience.
