Description

Technical Field

[0001] This application relates to the field of power distribution cabinet technology, and more specifically, to a power distribution cabinet with a cable plug. Background Technology

[0002] The cable entry holes of a distribution cabinet are a key structural design feature in a power system. They serve as channels for cables to connect internal and external equipment within the cabinet, enabling the input and distribution of electrical energy. These cable entry holes are typically located on the top, bottom, or side of the distribution cabinet, depending on the method of cable entry.

[0003] In related technologies, wiring holes in distribution cabinets are usually fitted with wiring hole covers. The main function of the wiring hole covers is to seal off excess space in the inlet and outlet holes to prevent moisture, dust, or even insects from entering the distribution cabinet, thereby avoiding a series of problems such as rusting of electrical equipment, decreased insulation, or poor contact.

[0004] However, in actual use, because the size of the cable guide cap cannot perfectly match the cable, a gap will remain between them, resulting in poor sealing. Especially in multi-cable scenarios, moisture can easily accumulate in the gap, thus accelerating the corrosion of the cable's outer layer. Utility Model Content

[0005] In view of this, embodiments of this application provide a distribution cabinet with a cable plug, which achieves dynamic sealing by storing putty in the inner cavity of the outer cable cover and using the pusher ring of the inner cable cover to push the putty to fill the cable gap.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A distribution cabinet with a cable plugger includes:

[0008] The cabinet body has a wire hole in the upper left corner of the back panel.

[0009] The outer wire-passing cover includes an inner ring and an outer ring arranged coaxially, and a first limiting ring connected to the ends of the two. The outer ring is embedded in the wire-passing hole, and the length of the inner ring is less than that of the outer ring. An inner cavity for storing putty is formed between the two.

[0010] An inner cable pass-through cover includes a sleeve with an outer diameter smaller than the inner diameter of the outer ring. A mud-pushing ring is fixedly disposed inside the sleeve, and a second limiting ring is fixedly disposed at its end. The inner diameter of the mud-pushing ring is adapted to the inner diameter of the inner ring.

[0011] The sleeve is inserted into the inner cavity, and the axial movement drives the mud-pushing ring to squeeze the mortar into the cable gap.

[0012] In some possible implementations, the inner wall of the outer ring is provided with an external thread, and the outer wall of the sleeve is provided with an internal thread that mates with the external thread.

[0013] In some possible implementations, a first annular groove is provided on the outer wall of the inner ring near the port, and a first sealing ring is provided in the first annular groove.

[0014] In some possible implementations, the inner ring of the mud-pushing ring is provided with a second annular groove near the port, and a second sealing ring is provided in the second annular groove.

[0015] In some possible implementations, the putty is a fire-retardant putty to fill the gaps between the cables during the pushing process.

[0016] In some possible implementations, the first limiting ring contacts and limits the outer surface of the back plate, and the second limiting ring abuts against the end of the outer wire cover during the slurry pushing process to control the slurry filling depth.

[0017] The power distribution cabinet with cable plug provided in this application embodiment has at least the following beneficial effects:

[0018] In the distribution cabinet with cable sealer provided in this application embodiment, an outer cable cover and an inner cable cover are embedded in the cable hole on the back panel of the cabinet. The outer cable cover is connected to the cable hole through an outer ring, and the cable is led out through the inner ring of the outer cable cover. A pusher ring is provided inside the sleeve of the inner cable cover. When the inner cable cover is inserted into the outer ring of the outer cable cover through the sleeve, the pusher ring pushes the sealant axially, causing the sealant to flow into the gap of the cable, thereby achieving an adaptive sealing function. Furthermore, this design can be applied to different cable sizes and has the characteristics of strong sealing performance and simple operation. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1-7 As shown, the power distribution cabinet with cable plug provided in this embodiment includes a cabinet body 100, an outer cable tray 200 and an inner cable tray 300. The cabinet body 100 is the main structure of the power distribution cabinet. A cable tray 110 is provided in the upper left corner of the back panel of the cabinet body 100. The cable tray 110 is used to lead out the cables connected to the electrical components inside the power distribution cabinet and distribute them.

[0031] The outer cable guide cover 200 is composed of a first limiting ring 230 at one end, an inner ring 220 connected to the end face of the first limiting ring 230, and an outer ring 210. The outer diameter of the first limiting ring 230 is larger than the outer diameter of the outer ring 210, the inner diameter of the first limiting ring 230 is equal to the inner diameter of the inner ring 220, and the length of the first limiting ring 230 is shorter than the length of the inner ring 220. The outer cable guide cover 200 is inserted into the cable hole 110 through the outer ring 210, and the surface of the first limiting ring 230 of the outer cable guide cover 200 contacts the outer surface of the back panel of the cabinet 100 to achieve the limiting function. Furthermore, an inner cavity 240 is formed between the inner wall of the outer ring 210 and the outer wall of the inner ring 220, and a sealant 250 is placed in this inner cavity 240. Preferably, the sealant 250 can be a fire-retardant sealant with a certain viscosity to provide a sealing effect.

[0032] In this embodiment, the inner cable cover 300 includes a sleeve 310 and a second limiting ring 330 fixedly connected to the sleeve 310. A pusher ring 320 is fixedly disposed inside the sleeve 310. Specifically, the outer diameter of the sleeve 310 of the inner cable cover 300 is adapted to the inner diameter of the outer ring 210 of the outer cable cover 200, so the inner cable cover 300 can be inserted into the outer ring 210 of the outer cable cover 200 through the sleeve 310. Furthermore, the inner diameter of the pusher ring 320 is adapted to the inner diameter of the inner ring 220 of the outer cable cover 200. During assembly, the sleeve 310 of the inner cable cover 300 is inserted into the inner ring 220 of the outer cable cover 200, and the pusher ring 320 pushes the putty 250 in the inner cavity 240 into the cable gap to achieve a seal.

[0033] The following is combined with Figures 1-7 The working principle and working process of the distribution cabinet with cable plug provided in the embodiments of this application are described.

[0034] First, insert the outer ring 210 of the outer cable cover 200 into the cable hole 110 of the back panel of the cabinet 100. The first limiting ring 230 makes contact with the outer surface of the back panel and limits the cable. The inner cavity 240 of the outer cable cover 200 is pre-filled with putty 250. Slightly insert the sleeve 310 of the inner cable cover 300 into the outer ring 210 of the outer cable cover 200. The cable is led out through the push ring 320 of the inner cable cover 300 and the inner ring 220 of the outer cable cover 200. Push the inner cable cover 300 to move it closer to the outer cable cover 200. At this time, the pusher ring 320 will push the putty 250 in the inner cavity 240 to flow evenly into the gap of the cable. When the second limit ring 330 is pushed to abut against the inner surface of the back plate, the putty 250 will completely fill the gap of the cable, thereby ensuring the sealing between the cable and the inner ring 220 of the outer cable cover 200.

[0035] In the distribution cabinet with cable plug provided in this embodiment, an outer cable cover 200 and an inner cable cover 300 are embedded in the cable hole 110 on the back plate of the cabinet 100. The outer cable cover 200 is connected to the cable hole 110 through an outer ring 210. The cable is led outward through the inner ring 220 of the outer cable cover 200. A pusher ring 320 is provided inside the sleeve 310 of the inner cable cover 300. When the inner cable cover 300 is inserted into the outer ring 210 of the outer cable cover 200 through the sleeve 310, the pusher ring 320 pushes the putty 250 axially, causing the putty 250 to flow into the gap of the cable, thereby achieving an adaptive sealing function. Furthermore, this design can be applied to different cable sizes and has the characteristics of strong sealing performance and simple operation.

[0036] In some embodiments, the inner wall of the outer ring 210 is provided with an external thread 400, and the outer wall of the sleeve 310 is provided with an internal thread 500 that mates with the external thread 400. The outer ring 210 and the sleeve 310 employ a threaded engagement structure, allowing the compression depth to be controlled by the rotation depth, enabling the putty 250 to adapt to the sealing requirements of gaps between different cables. Furthermore, the self-locking characteristic of the thread prevents sealing failure due to accidental detachment.

[0037] In some embodiments, such as Figure 6 and Figure 7 As shown, a first annular groove 600 is provided on the outer wall of the inner ring 220 near the port, and a first sealing ring 700 is provided within the first annular groove 600. Similarly, a second annular groove 800 is provided on the inner ring 220 of the pusher ring 320 near the port, and a second sealing ring 900 is provided within the second annular groove 800. This bidirectional sealing design not only prevents the putty 250 from seeping into the cabinet 100, but also reduces the contact between the putty 250 and air, thereby delaying its hardening time.

[0038] In some embodiments, the first limiting ring 230 contacts and limits the outer surface of the back plate, and the second limiting ring 330 abuts against the end of the outer wire cover 200 during the mud pushing process to control the filling depth of the putty 250.

[0039] The various embodiments or implementation methods described in this specification are presented in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the embodiments can be referred to each other.

[0040] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0041] Generally speaking, terms should be understood at least in part by their use in context.

Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0042] It should be readily understood that the terms “on,” “above,” and “on top of” in this disclosure should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on top of something” but also “on top of something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0043] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures.

[0044] As used herein, the term "substrate" refers to the material on which subsequent material layers are added. The substrate itself may be patterned. The material added on top of the substrate may be patterned or may remain unpatterned. Furthermore, the substrate may include a wide range of materials, such as silicon, germanium, gallium arsenide, indium phosphide, etc. Alternatively, the substrate may be made of a non-conductive material (e.g., glass, plastic, or sapphire wafers).

[0045] The term "layer" as used herein can refer to a portion of material comprising a region of thickness. A layer may extend over the entire underlying or overlying structure, or may have a extent smaller than that of the underlying or overlying structure. Furthermore, a layer may be a region of a homogeneous or non-homogeneous continuous structure, with a thickness less than that of the continuous structure. For example, a layer may be located between the top and bottom surfaces of the continuous structure, or between any pairs of lateral planes at the top and bottom surfaces. A layer may extend laterally, vertically, and / or along a tapered surface. A substrate may be a layer, and may include one or more layers, and / or may have one or more layers located on, above, and / or below it. A layer may include multiple layers. For example, an interconnect layer may include one or more conductor and contact layers (forming contacts, interconnects, and / or vias therein) and one or more dielectric layers.
