Description

Technical Field

[0001] This utility model relates to the field of wire harness sealing and fixing technology, and in particular to a split-type multi-diameter wire guide plate and a photovoltaic inverter. Background Technology

[0002] In industries such as power, telecommunications, and home appliances, it is often necessary to pass wire harnesses through the partitions of a housing. In existing technology, to prevent the ingress of foreign objects such as water and dust, a sealing structure is usually installed at the wire passage holes in the partition. Traditional sealing structures generally involve placing a rubber protective ring or injecting sealant into the wire passage holes.

[0003] The above structure has the following disadvantages: 1) The wire hole cannot be adjusted according to the outer diameter of the wire harness, and it is inconvenient to change the wire hole on site; 2) After the sealant has cured, it is inconvenient to replace the wire harness; 3) The sealing ring is prone to poor sealing. Utility Model Content

[0004] The present invention provides a split-type multi-diameter wiring board and a photovoltaic inverter, which can be used for wire harnesses of different diameters, and has good sealing effect and convenient wire harness replacement and installation.

[0005] The above-mentioned technical problems are solved by the following technical solutions:

[0006] A split multi-diameter wire guide plate includes a wire guide plate body, which includes two opposing substrates, each substrate having a wire guide area.

[0007] The threading area is provided with a plurality of semi-circular grooves distributed sequentially from the center outwards. Adjacent semi-circular grooves and the innermost semi-circular groove are provided with detachable partitions. When two substrates are snapped together, the corresponding semi-circular grooves are joined together to form a concentric annular threading channel for threading wire harnesses.

[0008] In one embodiment, both substrates are provided with a plurality of threading regions distributed along the length direction of the substrate and corresponding one-to-one, and at least two adjacent threading regions on each substrate partially overlap.

[0009] In two overlapping wiring regions of each of the substrates, a semi-annular boss is provided on the outer edge of the semi-annular groove in one wiring region and extending into the other wiring region. The semi-annular boss extends into the other wiring region and is fixedly connected to the corresponding partition.

[0010] In one embodiment, the semi-annular boss is inclined outward.

[0011] In one embodiment, the semi-annular grooves are symmetrically arranged on both the front and back sides of each substrate.

[0012] In one embodiment, the semi-annular groove is provided with a plurality of circumferentially distributed reinforcing ribs. The reinforcing rib in the outermost semi-annular groove is connected between the threading plate body and the corresponding partition, and the reinforcing ribs in the remaining semi-annular grooves are connected between two adjacent partitions.

[0013] In one embodiment, each of the partitions is provided with an identifier for identifying the wire harness diameter.

[0014] In one embodiment, the substrate is a rubber component or a silicone component.

[0015] In one embodiment, one of the two substrates having interlocking end faces has at least one of a protrusion and a groove on its end face, and the other substrate has at least one of the protrusion and the groove on its end face. Both the protrusion and the groove extend along the length of the substrate. When the two substrates are interlocked, the protrusion is embedded in the groove.

[0016] In one embodiment, the end faces of both substrates are provided with the protrusions and the grooves, and the protrusions and grooves on each substrate are spaced apart along the thickness direction of the substrate.

[0017] A photovoltaic inverter, including the split-type multi-diameter wiring board described in any of the above solutions.

[0018] The beneficial effects of this utility model are as follows:

[0019] The modular multi-diameter wire guide plate provided by this utility model features semi-annular grooves spaced at intervals in the wire guide area of ​​the substrate. These semi-annular grooves do not penetrate the main body of the guide plate, thus forming partitions in the wire guide area. The number of partitions that can be removed can be selected according to the wire diameter of the wire harness, allowing the wire guide area to accommodate wire harnesses of various diameters when the two substrates are interlocked. It is understood that the semi-annular grooves not penetrating the main body of the guide plate ensures the sealing of the guide plate during use. Furthermore, the semi-annular grooves not penetrating the main body create annular connecting plates at the bottom of the grooves, providing support for the partitions and ensuring a compressive force on the wire harness. When partial partition removal is required according to the wire harness specifications, the annular connecting plate is simply broken along the corresponding semi-annular groove to remove the partition. The wire harness then passes through the concentric annular wire guide channel formed after the partial partition removal. This split-type multi-diameter cable tray can accommodate both single-core and multi-core wires as needed, offering high practicality, flexibility, good sealing, and easy wire harness disassembly and replacement.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] like Figures 1-4 As shown, this utility model embodiment provides a split multi-diameter wire guide plate, which includes a wire guide plate body 1. The wire guide plate body 1 includes two substrates 11, and each substrate 11 is provided with a wire guide area 12. When the two substrates 11 are interlocked, the wire guide areas 12 on the two substrates 11 are aligned and used to guide the wire harness 100. Each substrate 11 has a semi-annular groove 121 arranged sequentially from the center of the wire guide area 12 outwards at its wire guide area 12. The semi-annular grooves 121 do not penetrate the wire guide plate body 1, so that a detachable partition 122 is provided between any two adjacent semi-annular grooves 121 and in the semi-annular groove 121 with the smallest diameter (i.e., located on the innermost side). When the two substrates 11 are interlocked, the semi-annular grooves 121 at the corresponding wire guide areas 12 on the two substrates 11 correspond one-to-one. Understandably, the corresponding partitions 122 on the two substrates 11 can be removed according to the wire diameter of the wire harness 100. When the two substrates 11 are fastened together, the position of the removed partitions 122 forms a concentric annular wire passage, and the wire harness 100 is clamped in the wire passage.

[0032] By providing semi-annular grooves 121 spaced apart in sequence in the wiring area 12 of the substrate 11, the semi-annular grooves 121 do not penetrate the wiring plate body 1, so that partitions 122 are formed in the wiring area 12 of the substrate 11. The number of partitions 122 that can be removed can be selected according to the wire diameter of the wire harness 100, so that when the two substrates 11 are interlocked, the wiring area 12 can be used for wire harnesses 100 of various wire diameters. It can be understood that the semi-annular grooves 121 do not penetrate the wiring plate body 1, ensuring that the wiring plate body 1 is safe during use. The sealing performance is good; in addition, the semi-annular groove 121 does not penetrate the wire guide plate body 1, so that the bottom of the semi-annular groove 121 forms an annular connecting plate connecting the partition 122. The annular connecting plate is used to provide support for the partition 122 to ensure that the wire harness 100 is compressed. When it is necessary to disassemble part of the partition 122 according to the specifications of the wire harness 100, it is only necessary to break the annular connecting plate along the corresponding semi-annular groove 121 to disassemble the partition 122. The wire harness 100 is passed through the concentric annular wire guide channel formed after the disassembled part of the partition 122.

[0033] This split-type multi-diameter cable tray can accommodate both single-core and multi-core wires as needed, offering high practicality, flexibility, and good sealing. The wire harness is 100% easy to disassemble and replace.

[0034] Optionally, the semi-annular grooves 121 are provided on both sides of the wire guide plate body 1, that is, both sides of the wire guide plate body 1 are provided with semi-annular grooves 121, and the semi-annular grooves 121 on both sides of the wire guide plate body 1 are not connected to each other. This structural design is more reasonable, so that the partition 122 can provide a more stable clamping force.

[0035] Optionally, both substrates 11 are provided with multiple wire-passing areas 12 distributed along the length direction of substrate 11 and aligned one by one, so that the wire-passing plate body 1 can pass multiple wire bundles 100 at the same time.

[0036] To improve the utilization rate of the threading plate body 1, refer to Figure 3 As shown, at least two adjacent wire-passing areas 12 on each substrate 11 partially overlap. In this embodiment, the wire-passing board body 1 is provided with five wire-passing areas 12, wherein the second wire-passing area 12 and the third wire-passing area 12 partially overlap, and the third wire-passing area 12 and the fourth wire-passing area 12 also partially overlap. This design enables the wire-passing board body 1 to simultaneously fix up to five wire harnesses 100.

[0037] It is understandable that when two wiring areas 12 partially overlap, the strength of the partition 122 at the overlapping part will decrease. Therefore, when installing the wire harness 100, the unremoved partition 122 needs to provide clamping force. Due to the reduced strength of the overlapping partition 122, the clamping force decreases. In order to reduce the attenuation of the clamping force of the partition 122 at the overlapping part of the two wiring areas 12, a semi-annular boss 123 is provided in one of the two overlapping wiring areas 12. The semi-annular boss 123 is provided at the outer edge of the semi-annular groove 121 of the selected wiring area 12 (the outer edge of the semi-annular groove 121 is the side away from the center of the wiring area 12). That is, a semi-annular boss 123 is provided at the outer edge of the semi-annular groove 121 in the selected wiring area 12 and extends to the other wiring area 12. The semi-annular boss 123 extends into the other wiring area 12 and is fixedly connected to the corresponding partition 122. In this embodiment, semi-annular bosses 123 are provided in the second and fourth threading areas 12. The two semi-annular grooves 121 located on the outer side of the second and fourth threading areas 12 extend into the third threading area 12. Therefore, semi-annular bosses 123 are provided on the outer edges of the two semi-annular grooves 121 located on the outer side of the second and fourth threading areas 12. The semi-annular bosses 123 extend into the third annular area and are fixedly connected to the corresponding partitions 122 to reduce the attenuation of the clamping force of the corresponding partitions 122 in the second, third, and fourth threading areas 12.

[0038] Optionally, the semi-circular boss 123 is inclined outward, that is, the semi-circular boss 123 has an outward draft angle. When the wire harness 100 is clamped in the wire passage, interference between the semi-circular boss 123 and the wire harness 100 can be avoided, so as to fix the wire harness 100.

[0039] Optionally, each partition 122 is provided with a mark for identifying the wire diameter of the wire harness 100, that is, each partition 122 is provided with a corresponding wire diameter mark, so that the user can disassemble the corresponding partition 122 according to the corresponding wire harness 100, making the operation more convenient.

[0040] Optionally, a plurality of circumferentially distributed reinforcing ribs 124 are provided in the semi-annular groove 121. The reinforcing rib 124 in the semi-annular groove 121 with the largest diameter (i.e. located on the outermost side) is connected between the wire guide plate body 1 and the corresponding partition plate 122. The reinforcing ribs 124 in the other semi-annular grooves 121 are all connected between two adjacent partition plates 122. By providing reinforcing ribs 124, the connection strength of the partition plates 122 can be provided.

[0041] Optionally, the main body 1 of the wire guide plate is made of rubber or silicone, that is, the base plate 11 is made of rubber or silicone, so that the base plate 11 has good elastic properties. When the two base plates 11 are fastened together, the two base plates 11 can elastically hold the wire harness 100 to form an interference fit on the wire harness 100, thereby achieving clamping and sealing.

[0042] To ensure a tight seal when the two substrates 11 are engaged, such as Figure 4 As shown, in the end faces where the two substrates 11 are interlocked, one substrate 11 has at least one of a protrusion 111 extending along the length direction of the substrate 11 and a groove 112, and the other substrate 11 has at least one of a groove 112 extending along the length direction of the substrate 11 and a protrusion 111. When the two substrates 11 are interlocked, the protrusion 111 can be embedded in the groove 112. This structure ensures accurate alignment of the two substrates 11 when they are interlocked, and the protrusion 111 and groove 112 also improve the sealing performance when the two substrates 11 are interlocked.

[0043] Furthermore, both substrates 11 have protrusions 111 and grooves 112 on their end faces, and the protrusions 111 and grooves 112 on each substrate 11 are spaced apart along the thickness direction of the substrate 11. When the two substrates 11 are fastened together, the protrusions 111 and grooves 112 on one substrate 11 are respectively engaged with the grooves 112 and protrusions 111 on the other substrate 11, further improving the sealing performance when the two substrates 11 are fastened together.

[0044] This utility model embodiment also provides a photovoltaic inverter, including a photovoltaic inverter body and a split multi-diameter cable tray disposed on the photovoltaic inverter body, so that the photovoltaic inverter can adapt to different specifications of wire harness 100, that is, it can adapt to single-core wires and multi-core wires.

[0045] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0046] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
