[0034] To more clearly illustrate the technical solutions in the embodiments of this utility model and the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort. Furthermore, the design orientation only indicates the relative positional relationship between the components, not the absolute positional relationship.

[0035] This utility model embodiment provides a structural sealing plate for cabinet cable entry. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 The structural sealing plate 1 includes a base plate 11 and a positioning rod 5. A wire-passing window 2 is opened in the middle of the base plate 11, and positioning rods 5 are provided on both sides of the wire-passing window 2. The wire-passing window 2 is used to introduce a cable 7 from the outside. The cable 7 passes through the base plate 11 from below the positioning rod 5 or from above the positioning rod 5.

[0036] In this application, the structural sealing plate 1 is generally used at the top and bottom of the cabinet where the cable needs to enter, and can be fixed according to the basic frame of the cabinet; for example, fixing holes are provided at the four corners of the structural sealing plate 1, and it is fixed to the cabinet through the fixing holes and screws at the four corners.

[0037] For example, see [link / reference] Figure 3 This is a schematic diagram of structural panel 1 applied to the bottom of the cabinet; please refer to... Figure 4 This is a schematic diagram of structural panel 1 applied to the top of the cabinet.

[0038] In specific applications, installation can be selected according to the actual situation:

[0039] If only the top of the cabinet has a cable entry requirement, a structural sealing plate 1 can be installed only at the top, and a conventional base plate structure can be used for sealing at the bottom. Single-end wiring can be carried out only at the top, and the cable can be introduced into / out of the cabinet from the top.

[0040] If only the bottom of the cabinet has a cable entry requirement, a structural sealing plate 1 can be installed at the bottom, and a conventional top plate structure can be used for sealing at the top. Single-end wiring is only carried out at the bottom, and the cable is introduced into / out of the cabinet from the bottom.

[0041] If there is a need for wiring at both the bottom and top of the cabinet, a structural sealing plate 1 can be installed at both the bottom and top to enable double-ended wiring. Cables can be introduced into / out of the cabinet from the top and bottom as close as possible.

[0042] The above scenario is a standard application. If there is a large demand for incoming lines on the side walls and rear wall of the cabinet, ports for incoming lines can be opened on the cabinet, and a fixed structural sealing plate 1 can be installed at the port.

[0043] In the embodiments of this application, the basic structure of the structural sealing plate 1 is a substrate 11, and a wire-passing window 2 is opened in the middle of the substrate 11. The wire-passing window 2 is used to introduce external cables 7. Positioning rods 5 can be set on both sides of the wire-passing window 2 to constrain the introduced cables 7.

[0044] Taking the orientation of the structural sealing plate 1 when it is installed and fixed at the bottom of the cabinet as an example, at this time, the structural sealing plate 1 is upright in the cabinet, and there is a suspension gap between the positioning rod 5 and the base plate 11. Preferably, the cable 7 can pass through the suspension gap, that is, the cable 7 passes through the bottom of the positioning rod 5. Figure 3 As shown in the diagram; in addition, it can also pass through from above the positioning rod 5, or of course, the cable 7 can pass through in both places.

[0045] When structural panel 1 is installed and fixed to the top of the cabinet, it is inverted, such as... Figure 4As shown, the suspension gap between the positioning rod 5 and the base plate 11 remains constant, while the structural sealing plate 1, which is fixed at the bottom, only changes in orientation. When introducing the cable 7, it is preferable to pass it through the suspension gap, i.e., the cable passes over the positioning rod 5, as shown. Figure 4 As shown in the diagram; in addition, it can also pass under the positioning rod 5, or of course, the cable 7 can pass through both places.

[0046] In this application, Figure 3 The diagram shows the scenario where cable 7 passes through the suspension gap. Figure 4 The diagram shows a scenario where cable 7 passes outside of positioning rod 5.

[0047] Understandably, when there are few cables 7, they can simply pass through the suspension gap without needing to be fixed; when there are many cables 7, some or all of the cables 7 can be fixed based on the positioning rod 5, and the passing position of the cables 7 can also be adjusted.

[0048] In the embodiments of this application, the positioning rod 5 is a vertical frame structure, the inner frame width of the vertical frame structure is greater than the width of the through window 2, and the top frame of the vertical frame structure is suspended above the substrate 11.

[0049] It is feasible to have a fixed frame structure with a fixed height and no adjustable suspension gap; or a telescopic frame structure with an adjustable height and suspension space, which can be adjusted according to the amount of wiring harness introduced, thus avoiding the impact of a fixed-height frame on the equipment installation space inside the cabinet.

[0050] Preferably, the positioning rod 5 and the base plate 11 can be detachably connected for easy separate transportation; of course, the positioning rod 5 and the base plate 11 can also be an integrated structure that can be transported together with the cabinet.

[0051] The frame structure of the positioning rod 5 can be of various forms, and can be selected independently according to the actual situation and wiring harness layout habits during implementation.

[0052] In one specific embodiment, the frame structure includes two uprights and a top rod that are vertically fixed to the substrate 11. The distance between the two uprights is greater than the width of the through window 2. The two ends of the top rod are fixed to the tops of the two uprights respectively, and the top rod is parallel to the substrate 11.

[0053] The width between the two uprights is the inner frame width; the top rod is the top frame, which is suspended above the base plate 11 to form a suspension gap, which is a closed type.

[0054] After entering through the cable passage window 2, cable 7 can pass through the closed suspension gap or over the top pole. The distance between the two uprights is greater than the width of the cable passage window 2, allowing more cables 7 to pass through in an orderly manner.

[0055] In another feasible embodiment, the frame structure can be L-shaped, consisting of only one upright and one top rod. The lower end of the upright is fixed vertically to the substrate 11, and one end of the top rod is fixed to the top of the upright. The top rod is suspended horizontally above the substrate 11.

[0056] The fixed position of the upright is located behind or in front of the wire-passing window 2, so that the limiting point of the inner frame width is outside the width boundary of the wire-passing window 2; the top rod is the top frame, suspended above the base plate 11, forming a suspension gap, which is semi-open.

[0057] The other end of the top rod can face the opposite direction of the wire harness fixing, so that the wire harness is stopped and positioned by the upright rod and will not fall loose from the opening; at the same time, when disassembling, it can be pulled out directly along the opening in the opposite direction without having too much intersection with other cables.

[0058] When the telescopic function is implemented, the upright can be a telescopic sleeve rod; when the detachable function is implemented, the upright and the base plate 11 can be detachably fixed, such as by threaded connection; furthermore, on this basis, the top rod and the upright can be detachably connected, for example, a detachable stop ring is provided at one end of the top rod, a collar is provided at the top of the upright, the top rod passes into the collar, and the stop ring is used to stop and fix it.

[0059] In the embodiments of this application, the opening of the wire-passing window 2 can be set to be relatively large, and a sliding positioning plate 3 can be provided on the substrate 11 to adjust the size of the opening of the wire-passing window 2 to accommodate the introduction requirements of different numbers of cables 7.

[0060] In one specific embodiment, a positioning plate 3 is slidably mounted on the substrate 11, and the positioning plate 3 is slidably disposed above the wire-passing window 2; by sliding the positioning plate 3, the positioning plate 3 blocks the wire-passing window 2, thereby adjusting the size of the wire-passing window 2.

[0061] A sliding assembly 4 can be provided on the substrate 11. The sliding assembly 4 is located on the front and rear sides of the wire-passing window 2, arranged in pairs, such as... Figure 1 As shown, the front and rear sides of the positioning plate 3 are respectively slidably engaged with the sliding components 4 on one side. Preferably, symmetrical sliding components 4 are provided on the front and rear sides of the wire guide window 2, and the positioning plate 3 is slidably disposed within the sliding components 4, with the sliding direction of the positioning plate 3 perpendicular to the direction of the positioning rod 5.

[0062] In one specific embodiment, the sliding kit 4 includes a fixing part and a suspended limiting part. The fixing part is fixed to the substrate 11, and the limiting part is suspended above the substrate 11 to form a sliding gap. The sliding gap faces the wire-passing window 2, and the positioning plate 3 is slidably disposed in the sliding gap.

[0063] The height of the sliding gap can be the same as or slightly less than the thickness of the positioning plate 3, so that the positioning plate 3 can be slidably inserted into the sliding gap and has the basic conditions for sliding.

[0064] It should be noted that a semi-open sliding gap is formed between the limiting part and the substrate 11. The two sliding gaps on the front and rear sides of the wire-passing window 2 cooperate to limit the sliding of the positioning plate 3, so that the sliding of the positioning plate 3 can cover the wire-passing window 2 and shield the wire-passing window 2, thereby realizing the adjustment of the opening size of the wire-passing window 2.

[0065] When the positioning plate 3 is assembled, the positioning plate 3 is inserted into the sliding gap from below the positioning rod 5. In this application, in the insertion direction of the positioning plate 3, the opening position of the wire-passing window 2 on the substrate 11 is located in the center of the setting position of the upright frame structure on the substrate 11, and the upright is located outside the opening area of ​​the wire-passing window 2, so that the sliding of the positioning plate 3 does not interfere with the positioning rod 5.

[0066] After the adjustment is completed, the positioning plate 3 can be fixed. Since the positioning plate 3 is located below the limiting part, the positioning plate 3 can be fixed based on the limiting part.

[0067] In one specific embodiment, the front and rear sides of the positioning plate 3 are provided with a plurality of positioning holes 31 evenly distributed within the sliding gap, and the limiting part is provided with a plurality of through holes 41. When the positioning plate 3 is slidably disposed within the sliding gap, the positioning holes 31 are located directly below the through holes 41. When the positioning holes 31 and the through holes 41 are aligned, the positioning plate 3 is fixed by the positioning holes 31 and the through holes 41.

[0068] It can be fixed by bolts, screws, etc. Before fixing, align the positioning hole 31 with the through hole 41 so that the two holes pass through each other from top to bottom. Then insert the bolt / screw between the two holes to lock the positioning plate 3 in place and fix its position.

[0069] The multiple positioning holes 31 and through holes 41 can be evenly spaced and arranged in a single row, such as... Figure 1 As shown in the figure, due to the variable number of cables 7, the positions of the two holes may not match well during alignment.

[0070] Therefore, to facilitate fixing, multiple through holes 41 can be formed on the limiting part at different densities, making it easier for the positioning hole 31 and the through holes 41 to align; for example, the density of the through holes 41 gradually decreases from the side closer to the positioning rod 5 to the rear. Of course, the density of the two holes can be reversed.

[0071] Preferably, the positioning plate 3 is fixed in place by means of uniformly spaced positioning holes 31 and through holes 41 with a density that gradually decreases from the positioning rod 5 to the rear.

[0072] In this application, one positioning plate 3 can be used to adjust the opening size of the wire-passing window 2, or multiple positioning plates 3 can be used to adjust the wire-passing window 2, with the preferred embodiment being the use of two positioning plates 3 for adjustment.

[0073] As a preferred embodiment, see [reference]. Figure 1 The base plate 11 is provided with two left-right symmetrical positioning plates 3. The front and rear sides of the wire passage window 2 are provided with two sets of left-right symmetrical sliding kits 4. The two positioning plates 3 together adjust the opening size of a wire passage window 2. The sliding stroke of the two positioning plates 3 can be synchronous or different, depending on the number of cables 7 on one side.

[0074] Specifically, a sliding assembly 4 is provided on the left and right sides of the front side of the wire-passing window 2, namely the front left assembly and the front right assembly, and a sliding assembly 4 is provided on the left and right sides of the rear side of the wire-passing window 2, namely the rear left assembly and the rear right assembly; two symmetrical positioning plates 3 are respectively provided on the left and right sides of the wire-passing window 2.

[0075] Among them, the front left kit and the rear left kit are the first group, which are used in conjunction with the positioning plate 3 on the left side; the front right kit and the rear right kit are the second group, which are used in conjunction with the positioning plate 3 on the right side; the two positioning plates 3 can slide relatively independently on both sides, and the opening and closing range on one side is controlled.

[0076] In this application, the two positioning plates 3 can completely close the wire-passing window 2; or a certain size gap can be left at the docking point so that the wire-passing window 2 is not completely closed.

[0077] Based on the actual situation, the number of cables 7 inserted may not be perfectly matched with the size of the opening of the cable passage window 2; for example, if multiple cables 7 are concentrated on one side of the opening, there will be gaps on the other side. The cables 7 cannot completely fill the opening of the cable passage window 2, and adjusting the size of the opening cannot completely eliminate the gaps; therefore, in order to prevent foreign objects from entering the cabinet, these gaps should be sealed.

[0078] As a feasible implementation, when the gap is small, it can be sealed with fireproof putty; when the gap is large, the sealing with fireproof putty needs to be combined with a supporting structure.

[0079] As a preferred embodiment, a rubber pad can be placed on the fixed positioning plate 3 to seal the opening of the wire-passing window 2, and a gap or port for the cable to pass through can be opened on the rubber pad to make the gap as small as possible.

[0080] For example, after the positioning plate 3 is fixed to the limiting part, a rubber pad is provided in the gap between the two positioning plates 3, and the rubber pad is laid flat to seal the gap.

[0081] For example, when only one positioning plate 3 is configured on the wire-passing window 2, a rubber pad is configured in the gap between the front end of the positioning plate 3 and the wire-passing window 2, and the rubber pad is laid flat to seal the gap.

[0082] The rubber pad has a threading slit, through which the cable passes; the threading slit is the center seam of the rubber pad running front to back; the threading slit is also a shrink hole, through which the cable passes.

[0083] This utility model also provides a cabinet with a port for cable entry. The aforementioned structural sealing plate 1 is installed at the port to facilitate cable entry / exit. Fixing holes can be provided at the four corners of the structural sealing plate 1, and the plate can be fixed to the port on the cabinet using screws through the four corner fixing holes.

[0084] Specifically, the structural sealing plate 1 is fixedly installed on the port, and the cables 7 outside the cabinet are introduced into the cabinet through the cable passage window 2; the cables 7 inside the cabinet are introduced and exited in the same way. The port for cable entry is generally opened at the top and / or bottom of the cabinet; however, for some practical needs, ports can also be opened on the side wall of the cabinet, and the structural sealing plate 1 can be installed and fixed on them.

[0085] It is understandable that the side wall where the port is opened is generally fixed and the port is not opened on the cabinet's opening and closing door, which is generally the front side wall; therefore, the port is generally opened on the left and right side walls and the rear side wall. Since some cabinets include two opening and closing doors, namely the front door on the front side wall and the rear door on the rear side wall, it is preferable that the port is opened on the left and right side walls.

[0086] In this application, the left and right sidewalls are Figure 3 , Figure 4 The middle section is the side wall 6. Following a conventional layout, structural panels 1 can be installed at the top and bottom of the cabinet (one or two structural panels 1 are mounted inside the cabinet). The two positioning rods 5 on the structural panels 1 are respectively positioned close to the two side walls 6 of the cabinet (left side wall and right side wall). Figure 3 , 4 As shown in the figure (the front and rear side walls are not shown), the cable 7 can quickly approach the cabinet after being positioned and constrained by the positioning rod 5. The cable 7 is laid out in a standardized manner, which helps to shape the cable harness for cabinet placement.

[0087] It is understandable that the cabinet's ribbed structure has multiple through holes for bundling. These through holes allow for easy visual positioning of the wire harness, enabling it to be laid along the ribs towards the center of the cabinet and guided to the equipment at a suitable location. The positioning rod 5 in this application helps position the wire harness and allows it to quickly approach the ribbed structure of the cabinet, ensuring that the wire harness is restrained after being introduced into the cabinet and does not occupy a large amount of internal cabinet space (bottom and top space).

[0088] Low-voltage distribution cabinets are prone to corrosion when used in environments with high levels of dust and moisture, which also reduces the insulation performance of the electrical components inside the cabinet. Therefore, improving the sealing performance of the cabinet and reducing the entry of dust and moisture into the cabinet can improve the durability of the distribution cabinet.

[0089] In this application, the cabinet is equipped with an openable side door, which may include a front side door and a rear side door. Correspondingly, the side walls include a left side wall and a right side wall. A sealing strip is provided between the side door and the cabinet door frame. For example, a 12mm wide * 6mm high foamed sealing strip can be applied to the contact surface between the front and rear side doors and the cabinet door frame (fixed beam) to improve the overall sealing performance of the cabinet.

[0090] Air intake grilles are provided on the side doors (front door, rear door) and / or side walls 6 (left side wall, right side wall) of the cabinet. A filter screen is installed inside the air intake grille, and the size of the filter screen is at least the same as the size of the air intake grille. For example, the air intake grille can be provided as needed, and can be located on the side door or side wall 6, or both. The filter screen can be made of nylon fiber synthetic resin, which can filter out dust and moisture from the air, reduce the risk of corrosion of electrical components inside the cabinet, and improve the durability of the electrical equipment inside the cabinet.

[0091] When laying and installing cables in the distribution cabinet and performing subsequent maintenance, the work can be carried out based on the structural characteristics of the structural sealing plate 1. There is no need to cut the sealing plate to enlarge the cable passage window 2, and the basic structure of the base plate 11 will not be damaged. The port sealing plate of the cabinet can maintain the structural integrity.

[0092] The structural sealing plate 1 can be made of stainless steel to avoid rust and damage, thus improving the durability of the cabinet. Positioning rods are set on the left and right sides of the wire passage window 2, and reinforcing ribs can be set on the front and rear sides of the wire passage window 2 to enhance the mechanical strength of the base plate. The length of the reinforcing rib is greater than the distance between the two positioning rods. The reinforcing rib supports the two positioning rods at the same time, so that the support effect of the positioning rods is stable, and the wire harness is effectively constrained, ensuring that the positioning rods and the base plate are not easily deformed by the rebound force of the wire harness.
