Description

Technical Field

[0001] The present invention relates to the technical field of electrical conduits, in particular to an ultraviolet-proof, highly light-transmitting, safe electrical conduit, a material for a flexible pipe connector, a flexible pipe connector and applications thereof. Background Art

[0002] In the electrical engineering field, low-voltage service expansion installations often require the use of electrical conduit to protect the wires. Traditional electrical conduit primarily uses white PVC (polyvinyl chloride) rigid pipe, which offers a high cost-effectiveness, but has some significant drawbacks in practical applications.

[0003] First, the current PVC rigid conduit is opaque, which makes it impossible for business expansion project acceptance personnel to directly inspect the installation process and quality of the wires in the conduit. This makes it difficult to detect problems such as insulation damage, broken wires, and power theft that may occur during the installation process. These problems not only increase the workload of daily inspections and maintenance, but may also lead to safety hazards or power loss. In addition, the material performance of traditional electrical conduits needs to be improved. When used outdoors, electrical conduits need to withstand the influence of various environmental factors such as ultraviolet radiation, high temperature, low temperature, and humidity. However, the performance of existing electrical conduit materials in terms of UV resistance, high temperature resistance, and corrosion resistance is not ideal, and they are prone to aging, brittleness, cracking, etc., which affect the safety and service life of the wires.

[0004] Secondly, the connection between the electrical conduit and the cable protection hose currently usually needs to be fixed with auxiliary materials such as glue or nails. This connection method is not only cumbersome to operate, but may also cause damage to the wires during the installation process. In addition, the connection method fixed with glue or nails may cause problems such as aging and loosening during long-term use due to environmental factors (such as ultraviolet radiation, high temperature, humidity, etc.), thereby reducing the effect of wire protection. In order to solve the above problems, the present invention proposes a flexible pipe connector that is easy to install and highly adaptable to meet the needs of modern electrical engineering. If the flexible pipe connector is prepared with a conventional hose, it will face the same problems as the electrical conduit when used outdoors. It needs to withstand the influence of various environmental factors such as ultraviolet radiation, high temperature, low temperature, humidity, etc., and is prone to aging, brittleness, and cracking.

[0049] Example 1

[0050] This embodiment provides a method for preparing a material for a flexible pipe connector, specifically comprising:

[0051] Formula of materials for flexible pipe connectors: Calculated by mass percentage of raw materials,

[0052] 100 parts of polyvinyl chloride resin SG-3, 12 parts of flame retardant (4 parts each of decabromodiphenylethane, brominated epoxy resin, and ammonium polyphosphate), 5 parts of toughening agent (fluororubber), 10 parts of plasticizer (6 parts of tricresyl phosphate, 4 parts of dioctyl adipate), 3 parts of antioxidant (antioxidant B225), 1 part of ultraviolet absorber (0.5 parts each of UV-3346 and Tinuvin P);

[0053] At this time, the mass ratio of the plasticizer, the antioxidant, and the ultraviolet absorber was 10:3:1.

[0054] After the raw materials are uniformly mixed, they are melt-extruded at 180° C. to obtain a material for a flexible pipe connector.

[0055] Example 2

[0056] The difference between this embodiment and embodiment 1 is that the number of parts of the plasticizer is adjusted to 5 parts, that is, the mass ratio of the plasticizer, antioxidant and ultraviolet absorber is 5:3:1. The rest of the preparation process is the same as that of embodiment 1 to obtain a material for a soft pipe connector.

[0057] Example 3

[0058] The difference between this embodiment and embodiment 1 is that the number of parts of the plasticizer is adjusted to 15 parts, that is, the mass ratio of the plasticizer, antioxidant and ultraviolet absorber is 15:3:1. The rest of the preparation process is the same as that of embodiment 1 to obtain a material for a flexible pipe connector.

[0059] Comparative Example 1

[0060] The difference between this comparative example and Example 1 is that the amount of plasticizer is adjusted to 0 parts, that is, the mass ratio of plasticizer, antioxidant and ultraviolet absorber is 15:3:1, and the rest of the preparation process is the same as Example 1 to obtain a material for a flexible pipe connector.

[0061] The performance of the flexible pipe connector materials prepared in the above examples and comparative examples was tested, and the results compared with those in Example 1 are shown in Table 1.

[0062] Table 1

[0063] Example 1 Example 2 Example 3 Comparative Example 1 Tensile strength / MPa 39.5 35.1 36.3 20.5 Elongation / % 350 300 310 230 Oxygen index 55 50 50 35 Self-extinguishing time / s 15 25 20 31 Sunlight aging resistance / h 2000 1800 1900 1000 Visible light transmittance / % 99％ 97％ 98％ 94％

[0064] As can be seen from the table above, adjusting the ratio of plasticizers, antioxidants, and UV absorbers in the raw materials has a significant impact on the performance of materials used in flexible pipe connectors. This is because the main function of plasticizers is to reduce the cohesive force between polymer molecular chains, thereby increasing the flexibility and plasticity of the material. In addition, they also work synergistically with antioxidants and UV absorbers. Too little plasticizer content will lead to enhanced interactions between polyvinyl chloride molecular chains, and the flexibility and ductility of the material will deteriorate. Too much plasticizer content will lead to reduced mechanical strength of the material. It may also interact with the UV absorber, reducing the efficiency of the UV absorber, and thus affecting the processing performance and final performance of the material. According to the results in the table above, the best technical effect can be achieved when the mass ratio of plasticizer, antioxidant, and UV absorber in the present invention is 10:3:1.

[0065] Example 4

[0066] The difference between this embodiment and embodiment 1 is that the amount of antioxidant is adjusted to 1 part, that is, the mass ratio of plasticizer, antioxidant and ultraviolet absorber is 10:1:1. The rest of the preparation process is the same as that of embodiment 1 to obtain a material for a flexible pipe connector.

[0067] Example 5

[0068] The difference between this embodiment and embodiment 1 is that the number of parts of the antioxidant is adjusted to 5 parts, that is, the mass ratio of the plasticizer, antioxidant and ultraviolet absorber is 10:5:1. The rest of the preparation process is the same as that of embodiment 1 to obtain a material for a soft pipe connector.

[0069] Comparative Example 2

[0070] The difference between this comparative example and Example 1 is that the amount of the antioxidant is adjusted to 0 parts, and the rest of the preparation process is the same as that of Example 1 to obtain a material for a flexible pipe connector.

[0071] The performance of the flexible pipe connector materials prepared in the above examples and comparative examples was tested, and the comparison results with those in Example 1 are shown in Table 2.

[0072] Table 2

[0073] Example 1 Example 4 Example 5 Comparative Example 2 Tensile strength / MPa 39.5 32.7 31.9 23.6 Elongation / % 350 325 333 265 Oxygen index 55 49 51 38 Self-extinguishing time / s 15 20 24 35 Sunlight aging resistance / h 2000 1700 1800 1200 Visible light transmittance / % 99％ 97％ 96％ 93％

[0074] As can be seen from the table above, adjusting the ratio of plasticizer, antioxidant, and UV absorber in the raw materials significantly affects the performance of the flexible pipe connector material. This is because the plasticizer, antioxidant, and UV absorber work synergistically. When the amount of toughening agent is adjusted, it may disrupt the original formula balance and affect the effects of the UV absorber and plasticizer. Adjusting the amount of toughening agent may change the overall formula ratio of the material, thereby affecting the dispersion effect and performance contribution of other ingredients. According to the results in the table above, the best technical effect is achieved when the mass ratio of plasticizer, antioxidant, and UV absorber in the present invention is 10:3:1.

[0075] Example 6

[0076] Reference Figure 1 This embodiment provides a flexible pipe connector, which is obtained by heating the flexible pipe connector material of Example 1 to 130° C., shaping it in a specific mold, and then cooling and solidifying it. The structure of the flexible pipe connector includes:

[0077] The main body 1 includes a first channel 11 penetrating the main body 1 and a second channel 12 concave along the inner wall of the first channel 11 along the end surface of the main body 1;

[0078] The mounting plate 2 is rotatably mounted on the outer wall of the main body 1 . The mounting plate 2 includes a notch 21 and a positioning hole 22 passing through the mounting plate 2 .

[0079] The first channel 11 extends through the main body 1, forming a cylindrical structure. A second channel 12 is recessed outwardly from the inner wall of the first channel 11, and the second channel 12 does not extend through the main body 1. This design allows the main body 1 to be placed over a structure that requires wiring. The hose outside the protected wiring is then inserted into the second channel 12, and the wiring is then routed underneath. This protects the wiring while preventing the hose from being inserted into the wiring installation area, preventing heat from melting the hose. It also provides dust protection. A strip-shaped mounting plate 2 is rotatably mounted on the outer wall of the main body 1. This design allows the strip-shaped mounting plate 2 to be rotated to accommodate different installation locations. For example, if a building has a recessed channel, the cable can be placed into the recessed channel, and the mounting plate 2 is then mounted on the outer wall of the wall. The cable is routed inside the recessed channel, solving the problem of inconvenient installation within a cable groove. Several positioning holes 22 are drilled in an array on the mounting plate 2. This allows the main body 1 to be hung on the wall directly using the positioning holes 22 of the mounting plate 2, using bolts or other columns on the wall.

[0080] In summary, the main body 1 is installed at the cable connector required by the device, and then the cable and the device are installed, such as using the mounting plate 2 to install the main body 1 on the corresponding wall or the outer wall of the cabinet; then the cable is passed through the hose, and the hose is inserted into the inside of the second channel 12, and then along the arranged cable route, the mounting plate 2 is used to fix it to the cable structure at the other end.

[0081] As an optional embodiment, a second channel 12 is provided along the end surface of the main body 1 and is recessed along the inner wall of the first channel 11 .

[0082] Among them, the inner diameter of the second channel 12 is larger than the inner diameter of the first channel 11. The advantage of this design is that it can be used to protect the hose connection of the cable. By utilizing the deformability of the hose, the hose can be directly inserted into the second channel 12, and the main body 1 can play a connecting role. The advantage of this design is that a main body 1 can be installed at the turning point of the cable, and then installed in conjunction with the cable routing.

[0083] As an optional embodiment, the second channel 12 is recessed toward the inner wall of the first channel 11 to form a first surface 121 .

[0084] Among them, the radius of the second channel 12 gradually decreases toward the inside of the main body 1 to form a first surface 121, that is, the first surface 121 forms an inclined surface; the advantage of this design is that when the hose is inserted into the inside of the main body 1, the radius continues to decrease, which will squeeze the hose and increase the pressure on the hose, thereby increasing the friction and facilitating the connection between the hose and the main body 1.

[0085] In summary, the main body 1 is installed at the cable connector required by the device, and then the cable and the device are installed, such as using the mounting plate 2 to install the main body 1 on the corresponding wall or the outer wall of the cabinet; then the cable is passed through the hose, and then the hose is inserted into the inside of the second channel 12. By utilizing the characteristic that the radius of the second channel 12 gradually decreases, the hose can be squeezed to a certain extent, and the cable can also be pressurized to a certain extent. This is convenient for installation and also increases the tightness of the installation, which is more convenient for disassembly; when using, it is only necessary to use force to push the hose inward along the surface of the second channel 12. Due to the characteristics of the hose, the hose will also fit the second channel 12, and it will also prevent water from entering the main body 1, which can ensure both the convenience of installation and the sealing; then, along the arranged cable route, use the mounting plate 2 to fix it to the cable structure at the other end. While ensuring the convenience of installation, it can also ensure that the hose protects the cable directly exposed to the outside.

[0086] As an optional embodiment, the mounting plate 2 includes a first surface 20 , and a notch 21 is formed by being recessed inwardly along the first surface 20 .

[0087] Among them, Figure 1The first surface 20 of the mounting plate 2 is close to the main body 1, and a notch 21 is recessed toward the first side of the first surface 20 to form a trapezoidal mounting plate 2. The advantage of this design is that it can be used when installing bolts or screws, so that the bolts or screws are flush with the mounting plate 2, reducing the protruding structure and the possibility of being scratched. At the same time, it can also make the installation beautiful.

[0088] Furthermore, two mounting plates 2 are provided, and the first surfaces 20 of the two mounting plates 2 are not in the same plane.

[0089] Among them, two mounting plates 2 are arranged on the outer wall of the main body 1, wherein the first surface 20 of one mounting plate 2 is close to the main body 1, and the first surface 20 of the other mounting plate 2 is facing away from the main body 1, forming a Figure 1 As shown, the notch 21 is half the thickness of the mounting plate 2. The advantage of this design is that Figure 3 As shown, when in use, two main bodies 1 can be installed, and then the two mounting plates 2 can be fitted together so that the notch 21 fits with the mounting plate 2, so that the two mounting plates 2 can overlap partially, saving installation space and facilitating the problem of multiple rows of wiring, solving the problem of the prior art that each cable needs to be connected by nails.

[0090] Furthermore, a plurality of positioning holes 22 are provided.

[0091] A plurality of positioning holes 22 are punched on the surface of the mounting plate 2 , and the overlapping positions between the positioning holes 22 can be controlled according to the required space, so that the cables are arranged at the same and neat intervals.

[0092] Based on the above embodiments, Figures 1 to 4 As shown, two main bodies 1 are provided.

[0093] Among them, the two main bodies 1 fit together, and the second channels 12 expand outward. The advantage of this design is that the hose can be connected to both ends of the main body 1. The main body 1 can be installed at one end of the equipment wiring and the hose can be connected. At the same time, the structure of the two main bodies 1 fitting together can facilitate the connection of hoses at both ends.

[0094] Furthermore, a first elastic member 3 is provided between the two main bodies 1 .

[0095] Among them, a first elastic member 3 is used between the two main bodies 1. The first elastic member 3 is made of a deformable material, such as a shock-absorbing airbag, a silicone elastic band, etc.; the advantage of this design is that the two main bodies 1 can be stretched and contracted; at the same time, the two main bodies 1 can also be installed in different positions.

[0096] In summary, the two main bodies 1 are connected by the first elastic member 3, and the two main bodies 1 can be installed in different places according to the actual application. For example, the main body 1 can be installed on both sides of the wall at the corner of the wall. The advantage of this design is that, Figure 5 As shown, the elasticity of the first elastic member 3 can be utilized to adapt to the curvature of different wall corners.

[0097] Beneficial effect: The two main bodies 1 are connected by the first elastic member 3, which can be used to protect the cable installation location and realize the connection between multiple sections of hoses, and can adapt to different installation environments.

[0098] As an optional embodiment, Figures 6-7 The mounting plate 2 is slidably arranged on the outer surface of the main body 1 .

[0099] An annular groove 13 is provided on the outer wall of the main body 1 ; a moving block 23 that can slide along the inner portion of the annular groove 13 is provided on one end of the mounting plate 2 close to the main body 1 .

[0100] Among them, there is an annular groove on the outer wall of the main body 1, and the annular groove 13 is an arc groove with an arc angle greater than 180°. The moving block 23 is a cylindrical structure and can slide along the inside of the annular groove 13. The advantage of this design is that the mounting plate 2 can be slid to a suitable position according to the actual situation on site to install and fix the main body 1; Figure 7 As shown, the position of the mounting plate 2 can be adjusted according to actual conditions.

[0101] In summary, the present invention discloses a UV-resistant, highly transmissive, safe electrical conduit, a material for a flexible pipe connector, a flexible pipe connector, and its applications. The conduit comprises a main body, the main body including a first channel extending through the main body; a mounting plate rotatably mounted on the outer wall of the main body, the mounting plate including a notch and a positioning hole extending through the mounting plate; and a first elastic member connecting the two main bodies. The conduit can be used to protect cable installations, connect multiple hose sections, and adapt to various installation environments. Furthermore, the material has been improved, with the synergistic effects of a plasticizer, an antioxidant, and a UV absorber effectively enhancing the conduit's compressive and impact resistance, toughness, high-temperature resistance, and corrosion resistance.

[0102] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
