Abstract
Description
Technical Field
[0001] This utility model relates to the field of threading board technology, specifically a cold-shrink threading board. Background Technology
[0002] In industries such as photovoltaics, energy storage, communications, wind power, and electricity, cables are essential connection tools. When cables enter the enclosure from the external environment, cable management boards are used to achieve a seal. Cable management boards not only fix the cable to the enclosure panel but also tighten the cable due to their unique elastic material and shape to achieve a seal. To achieve a good waterproof seal, the inlet and outlet holes of the cable management board are usually made relatively small. The board must be opened during cable pulling, which results in greater resistance and low efficiency during operation, and also poses a risk of damaging the cable management board. This places high demands on operators to strictly adhere to construction specifications. These drawbacks are particularly pronounced when the cable diameter is large.
[0003] To address the aforementioned issues, we have made improvements by proposing a cold-shrink threading board. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0005] This utility model provides a cold-shrink cable tray, including a chassis, cables and a cable tray body. The cable tray body is made of an elastomer and is provided with a secondary cable tray and a main cable tray.
[0006] The main threading port is equipped with a cold shrink tube, and the end of the cold shrink tube is provided with a drawstring.
[0007] The main body of the threading plate has an embedded skeleton inside the elastic body, and the top two parts of the skeleton extend out of the elastic body to form wing plates.
[0008] Side clips are provided on the side edges of the main body of the threading plate;
[0009] The bottom of the chassis is provided with a panel slot, the side of the panel slot is provided with an opening, and the inner edge of the panel slot is provided with a slot.
[0010] Limiting components are provided on both sides of the inner bottom surface of the chassis.
[0011] As a preferred technical solution of this utility model, the cold shrink tube is formed by pre-fixing the shape of the plastic support strip after spiral winding, and the draw strip is placed at the end of the main threading port.
[0012] As a preferred technical solution of this utility model, the side clips and slots of the threading plate body are shaped and positioned in accordance with each other, and the threading plate body is inserted from the opening of the panel slot.
[0013] As a preferred technical solution of this utility model, the limiting member is welded to the inner bottom surface of the chassis, the front end of the limiting member is provided with bolt holes, the two end wing plates of the frame are provided with bolt holes corresponding to the positions of the limiting member, and bolts are installed between the two bolt holes.
[0014] As a preferred embodiment of this utility model, the front of the chassis is hinged with a cover plate, and a sealing strip is installed on the inner surface of the cover plate.
[0015] As a preferred embodiment of this utility model, the cable is inserted into the main body of the cable guide plate from the main cable guide port.
[0016] The beneficial effects of this utility model are:
[0017] 1. This type of cold-shrink cable tray uses a cold-shrink tube made of plastic support strips wound in a spiral shape to open the main cable opening from the inside out, fixing the shape of the inlet and outlet of the main cable opening. A pull strip is left at the end of the cold-shrink tube. First, the cable is passed through the cold-shrink tube, and the installation position and length of the cable are adjusted. After installation, pulling the pull strip will cause the cold-shrink tube to gradually collapse. The cable tray's elastic body returns to its smallest diameter when it is in a free state, thereby tightly wrapping the cable and tightening it to achieve a good sealing effect during cable installation.
[0018] 2. Insert the cable guide plate into the side opening of the panel slot. During the side pushing process, there is no need to change the external structure and elasticity of the cable guide plate body, so as to avoid damage to the cable guide plate and pull on the already passed cables. After pushing the cable guide plate into the slot, tighten the wing plate with bolts and fasten the cover plate to complete the assembly of the cold shrink cable guide plate. The installation is convenient and quick and can effectively extend the overall service life of the cable guide plate. Attached Figure Description

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0027] Example: Figure 1-5 As shown, a cold-shrink cable tray includes a chassis 1, a cable 2 and a cable tray body 3. The cable tray body 3 is made of an elastomer and is provided with a secondary cable tray 10 and a main cable tray 15.
[0028] The main threading port 15 has a built-in cold shrink tube 9, and the end of the cold shrink tube 9 is provided with a drawstring 16;
[0029] A skeleton 11 is embedded inside the elastic body of the threading plate body 3, and the top two parts of the skeleton 11 extend out of the elastic body to form a wing plate 13.
[0030] Side clips 14 are provided on the side edge of the main body 3 of the threading plate;
[0031] The bottom of the chassis 1 is provided with a panel slot 6, the side of the panel slot 6 is set as an opening, and the inner edge of the panel slot 6 is provided with a slot 12.
[0032] Limiting components 7 are provided on both sides of the inner bottom surface of the chassis 1.
[0033] The cold shrink tubing 9 is formed by pre-fixing the shape of the plastic support strip by spiral winding, and the drawstring 16 is placed at the end of the main threading port 15.
[0034] The side clips 14 and the slots 12 of the main body 3 of the cable guide plate are in the same shape and position, and the main body 3 of the cable guide plate is inserted from the opening of the panel slot 6.
[0035] The limiting component 7 is welded to the inner bottom surface of the chassis 1. The front end of the limiting component 7 has bolt holes. The two end wing plates 13 of the frame 11 have bolt holes corresponding to the positions of the limiting component 7. Bolts 8 are installed between the two bolt holes.
[0036] A cover plate 4 is hinged to the front of the chassis 1, and a sealing strip 5 is installed on the inner surface of the cover plate 4.
[0037] Cable 2 is inserted into the main body of the cable tray 3 from the main cable insertion port 15.
[0038] Working principle: In use, this type of cold-shrink cable tray uses a cold-shrink tube 9, which is made of plastic support strips wound in a spiral shape, to open the main cable opening 15 from the inside out, fixing the shape of the cable inlet and outlet of the main cable opening 15. A pull tab 16 is left at the end of the cold-shrink tube 9. First, the cable 2 is passed through the cold-shrink tube 9, and the installation position and length of the cable 2 are adjusted. After installation, pulling the pull tab 16 will cause the cold-shrink tube to gradually collapse, and the cable tray body 3 will return to its smaller diameter when the elastic body returns to its free state, thus tightly wrapping the cable 2 and tightening it, achieving a good sealing effect during the installation of the cable 2. The cable tray body 3 is inserted into the side opening of the panel slot 6. During the side push-in process, there is no need to change the external structure and elasticity of the cable tray body 3, avoiding damage to the cable tray body 3 and not pulling the already passed cable 2. After pushing the cable tray body 3 into the panel slot 6, the wing plate 13 is locked with bolts 8, and the cover plate 4 is fastened, thus completing the overall assembly.
