Technical Field

[0001] The present application relates to the technical field of power cable installation, and in particular to a multi-layer threading plate. In addition, the present application also relates to a cabinet including the multi-layer threading plate. Background Art

[0002] Nowadays, the electric control cabinets used in the communication and other industries generally use cable connectors to connect the cables for protection wiring. Usually, the electric control cabinets and communication cabinets need to connect many cables to receive and transmit power and signals, which requires the installation of many cable connectors on the cabinets. The existing cable connectors are all threaded connectors. The threaded connectors need to be installed on the cabinet first, and then they need to be tightened with nuts inside the cabinet. When threading, they also need to be tightened with nuts.

[0003] However, the installation of cable connectors is inconvenient and requires a lot of man-hours. At the same time, the cable connectors take up a lot of space. Different specifications of connectors are required for wiring cables of different diameters. Each time a cable connector is installed, a corresponding hole must be opened on the cabinet. In addition, the subsequent increase or decrease of cables, maintenance and update of the electric control cabinet have made the disadvantages of the application of cable connectors increasingly prominent. Although there are threading plate products on the market, their perforation aperture is a single fixed aperture, which has certain limitations for the passage of cables of different scenarios and specifications.

[0004] Therefore, in response to the above technical problems, how to provide a multi-layer threading plate with high adaptability, convenient and flexible use is a technical problem that technical personnel in this field need to solve. Utility Model Content

[0016] The second threading sheath is nested in the previous second threading sheath in sequence;

[0017] A plurality of the second threading sheaths are embedded in the previous second threading sheath in parallel.

[0018] Preferably, the second threading sheaths are nested in sequence, wherein the maximum diameter of the latter second threading sheath is located inside the former second threading sheath, and the maximum outer diameter of the latter second threading sheath is greater than the opening diameters at both ends of the former second threading sheath.

[0019] Preferably, the plurality of second threading sheaths nested in parallel are independent of each other and are interference-fitted or integrated, and the plurality of second threading sheaths nested in parallel form an outer ring that is circumferentially interference-sealed with the previous second threading sheath.

[0020] Preferably, the end of the second threading sheath is provided with a dragging head extending outside.

[0021] A cabinet body comprises the multi-layer threading plate described in any one of the above items.

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] It should be noted that in this embodiment, the directions or positional relationships indicated by "upper", "lower", "front", "back", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0031] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figure 1 As shown, in this embodiment, a multi-layer threading plate is provided, which includes a main body 1 installed at the opening of the cabinet. Generally speaking, cables can enter and exit through the opening on the cabinet, and the threading plate of the present application can replace the function of the existing cable connector and improve the reliability of the cable.

[0033] The main body 1 is provided with a plurality of wire holes corresponding to the cables in the cabinet to assist the cables in entering and exiting the cabinet. Different from the prior art, the present application is provided with a wire threading sheath at the wire threading hole, and a wire threading hole 5 is provided on the wire threading sheath. After the cable passes through the wire threading hole and the wire threading hole 5, it is connected to the external components.

[0034] It should be noted that the threading sheath includes a first threading sheath 2 and a second threading sheath 3. Figure 1 , the first threading sheath 2 is fixedly connected to the main body 1, and can provide a fixed threading hole 5 aperture. On this basis, the second threading sheath 3 can be embedded in part of the first threading sheath 2 to form a multi-layer threading sheath. In other words, when the first threading sheath 2 cannot meet the aperture of the threading hole 5 required by the actual cable, the second threading sheath 3 can be nested and stacked in the first threading sheath 2 to adjust the actual aperture of the threading hole 5 to meet the requirements of cables of different specifications. Of course, if the first threading sheath 2 has already met the actual threading hole 5 aperture required by the cable, then there is no need to add the second threading sheath 3.

[0035] Considering the sealing of the cable when entering the cabinet, and the stability when the second threading sheath 3 is matched with the first threading sheath 2, the second threading sheath 3 is also set to be interference-sealed with the first threading sheath 2. That is to say, during the nesting process of the second threading sheath 3 and the first threading sheath 2, the sealing setting of the two can be achieved by interference fit, and the interference fit has a high stability effect, preventing the second threading sheath 3 from accidentally falling off.

[0036] In addition, based on the first threading sheath 2, the second threading sheath 3 is required to change the diameter of the threading hole 5, and the second threading sheath 3 is nested in the first threading sheath 2. Therefore, the threading hole 5 opening diameter of the second threading sheath 3 is smaller than the corresponding threading hole 5 opening diameter of the first threading sheath 2, so that according to the threading hole 5 diameter actually required by the cable, the second threading sheath 3 with different opening diameters or the second threading sheath 3 with different layers are selected.

[0037] On the basis of the above embodiment, there are two situations after the cable passes through the threading hole 5. One is that the threading hole 5 of the first threading sheath 2 has met the actual needs of the cable, the cable passes through the first threading sheath 2, and the cable has an interference fit with the first threading sheath 2 along its circumference to ensure its reliability; the other is that the actual needs of the cable are met after the second threading sheath 3 is nested. At this time, the cable passes through the second threading sheath 33, and the cable has an interference fit with the second threading sheath 3 along its circumference to ensure its reliability.

[0038] In summary, the present application designs a wire threading sheath so that multiple wire threading sheaths can be nested and stacked to form wire threading holes 5 with different apertures. When in use, the unnecessary parts can be directly pulled out according to actual needs, or the wire threading sheaths with the actual required wire threading hole diameter can be re-nested. On the basis of one wire threading hole, wire threading holes 5 with different apertures can be selected according to different specifications of cables. The use is convenient and flexible, and the adaptability is high.

[0039] In order to make the second threading sheath 3 more flexible and convenient to cooperate with the first threading sheath 2, while satisfying the conditions of interference sealing fit and achieving the purpose of not damaging the cable insulation layer, the threading sheath is set to be an elastic material, that is, the first threading sheath 2 and the second threading sheath 3 are both elastic materials, which can be rubber insulating materials, such as rubber materials.

[0040] Furthermore, the first threading sheath 2 can be formed integrally with the main body 1, thereby ensuring the stability of the first threading sheath 2 and also improving the stability of the first threading sheath 2 when it is matched with the second threading sheath 3. Since the threading sheath is made of elastic material, when the second threading sheath 3 is matched with the first threading sheath 2, or when the second threading sheaths 3 are matched with each other, it can be more easily disassembled and replaced.

[0041] The first threading sheath 2 and the second threading sheath 3 are both hollow conical structures with small outer diameters at both ends and large outer diameters in the middle. That is, when forming the threading hole 5, the two ends of the threading hole 5 have small apertures, so that the small apertures at both ends of the threading hole 5 are used to achieve fixed sealing of the cable. Of course, please refer to Figure 2 The tapered threading sheath also makes it easier to nest the first threading sheath 2 and the second threading sheath 3 , so that the second threading sheath 3 is stabilized in the middle area of ​​the first threading sheath 2 .

[0042] It should be noted that, depending on the cable specifications, the threading sheath may have the following situations:

[0043] 1. The first threading sheath 2 has met the actual needs of the cable, which has been stated above and will not be described in detail here;

[0044] Second, it is only necessary to embed a second threading sheath 3 in the first threading sheath 2 to meet the actual needs of the cable. In this case, the maximum outer diameter of the second threading sheath 3 is located inside the first threading sheath 2, and the maximum outer diameter of the second threading sheath 3 is larger than the opening diameters at both ends of the first threading sheath 2, thereby preventing the second threading sheath 3 from accidentally falling off from the threading hole 5 of the first threading sheath 2;

[0045] The second wire threading sheath 3 may have one wire threading hole 5 or may be provided with a plurality of wire threading holes 5, so that cables of various specifications can pass through one wire threading hole without affecting each other.

[0046] 3. It is necessary to embed multiple second threading sheaths 3 in the first threading sheath 2. At this time, there are also two situations. One is that part (two or more) of the second threading sheaths 3 are embedded in the first threading sheath 2, and the other part of the second threading sheath 3 is embedded in the previous second threading sheath 3; the other is that part (one) of the second threading sheath 3 is embedded in the first threading sheath 2, and the other part of the second threading sheath 3 is embedded in the previous second threading sheath 3, and the adjacent second threading sheaths 3 are interference-sealed.

[0047] For the third case, that is, when part of the second threading sheath 3 is embedded in the previous second threading sheath 3, there are two possibilities. One possibility is that the second threading sheath 3 is sequentially nested in the previous second threading sheath 3 to form a stacked multi-layer threading sheath; the other possibility is that multiple second threading sheaths 3 are embedded in the previous second threading sheath 3 in parallel. Please refer to Figure 2 .

[0048] It should be pointed out that for the above-mentioned various settings of the threading sheaths, the present application aims to emphasize how to achieve diversified adjustment of the aperture of the threading hole 5 through multiple different levels of threading sheaths, so as to meet the needs of different cables, while making disassembly and replacement more flexible and convenient, thereby improving work efficiency.

[0049] Then, for the second threading sheaths 3 nested in sequence, the maximum diameter of the latter second threading sheath 3 is located inside the former second threading sheath 3, and the maximum outer diameter of the latter second threading sheath 3 is greater than the opening diameters at both ends of the former second threading sheath 3. The principle here is similar to that of the second threading sheath 3 being embedded in the first threading sheath 2, and will not be repeated.

[0050] It should be noted that the second threading sheaths 3 nested in parallel may be multiple second threading sheaths 3 that are independent of each other and have an interference fit; or multiple second threading sheaths 3 may be integrally arranged to form a form similar to that of one second threading sheath 3 with multiple threading holes 5.

[0051] Regardless of whether it is a plurality of relatively independent second threading sheaths 3 or a plurality of integrated second threading sheaths 3, they are all arranged in parallel within the previous second threading sheath 3, so that the second threading sheaths 3 after being arranged in parallel form an outer ring that is circumferentially interference-sealed with the previous second threading sheath 3, thereby ensuring the sealing effect and stabilization effect between the threading sheaths.

[0052] In addition, there is no excessive restriction on the size of the first threading sheath 2, and the size can be determined according to the actual situation. Figure 3 .

[0053] Considering that the nested threading sheaths may be inconvenient to disassemble, a drag head 4 can be provided at the end of the second threading sheath 3, and the drag head 4 extends outside the second threading sheath 3. The operator can directly pinch and drag the drag head 4, thereby facilitating the disassembly of the second threading sheath 3.

[0054] The present application also provides a cabinet, which includes any of the multi-layer threading plates mentioned above, and of course also includes other necessary components that constitute the cabinet, which will not be described here, please refer to the prior art.

[0055] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0056] Specific examples are used herein to illustrate the principles and implementation methods of the present application, and the description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
