Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, and in particular to a protective structure and a flame-retardant computer cable. Background Technology

[0002] With the widespread use of computers and computer network systems, cables are increasingly used in various environments, especially in important locations such as data centers, high-rise buildings, subways, and power plants. In critical facilities like data centers, a large number of computer cables undertake important tasks such as power transmission and network transmission. These locations have strict requirements for the flame-retardant and fire-resistant properties of cables to ensure safety by minimizing casualties and equipment damage in the event of a fire. Traditional computer cables generally do not have flame-retardant requirements, or the requirements for flame-retardant levels are not high, which can no longer meet the demands of today's rapidly developing industries for higher-performance computer cable products. Furthermore, common computer cables often consist of multiple conductors bundled together, which makes cable management and wiring difficult, increasing the complexity and difficulty of cabling, and also easily causing interference, thus hindering usability.

[0003] Therefore, in order to meet the demands of modern computer systems for rapid data transmission, as well as to satisfy more stringent requirements for flame retardancy, fire resistance, and anti-interference capabilities, it is necessary to design a computer cable with higher flame retardancy and anti-interference capabilities.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0026] Example 1

[0027] Reference Figure 1This is the first embodiment of the present invention. This embodiment provides a protective structure, including a receiving unit 100, which includes a support 101, a first shielding layer 102 disposed on the outer wall of the support 101, a first wrapping strap 103 disposed on the outer wall of the support 101, a second shielding layer 104 disposed on the outer wall of the first wrapping strap 103, and a third shielding layer 105 disposed on the outer wall of the second shielding layer 104; and a flame-retardant unit 200, which includes a first fireproof layer 201 disposed on the outer wall of the third shielding layer 105, a heat dissipation support 202 disposed on the outer wall of the first fireproof layer 201, a second fireproof layer 203 disposed on the outer wall of the heat dissipation support 202, and a first protective sleeve 204 disposed on the outer wall of the second fireproof layer 203.

[0028] The first wrapping tape 103, viewed in cross-section, is a ring, essentially a cylinder. Within the space enclosed by the first wrapping tape 103 are a support 101 and a first shielding layer 102. The support 101 divides the space enclosed by the first wrapping tape 103 into at least one region. Dividing the internal space of the first wrapping tape 103 into multiple regions facilitates cable cabling and subsequent installation and wiring. Each region has its own first shielding layer 102, which is a copper wire braided shield. The first wrapping tape 103 is made of polyester tape to prevent the braided copper wire shield from puncturing the insulation and to prevent the cable cores from loosening. The second shielding layer 104, like the first shielding layer 102, is a copper wire braided shield. The third shielding layer 105, like the second shielding layer 104, is also a copper wire braided shield. The fireproof layer 201 is made of fire-resistant silicone rubber composite tape, which is a fire-resistant material with excellent high-temperature resistance and flame resistance. The heat dissipation support 202 has an arc-shaped cross-section. The heat dissipation support 202 and the first fireproof layer 201 form a semicircle with an arc cross-section outside the arc. The heat dissipation support 202 is made of TPE (thermoplastic polypropylene), which increases the heat dissipation capacity of the cable and also improves the impact resistance of the cable. The inner wall of the second fireproof layer 203 is in contact with the apex of the arc of the heat dissipation support 202. The second fireproof layer 203 is made of fire-resistant silicone rubber composite tape of the same material as the first fireproof layer 201. The first sheath 204 is in close contact with the outer wall of the second fireproof layer 203. The first sheath 204 is made of flame-retardant polyethylene material, which further improves the flame-retardant and fire-resistant performance of the cable.

[0029] In use, the internal support 101 supports the internal first wrapping tape 103 while dividing the internal space of the first wrapping tape 103 into several parts. The number of parts divided by the support 101 is increased or decreased according to the user's usage. The support 101 has a hollow structure for heat dissipation. Each space in the first wrapping tape 103 divided by the support 101 is equipped with a first shielding layer 102. When the external temperature rises or an open flame is present, the first sheath 204 acts as the first layer of fire protection, preventing the open flame from directly contacting the inside of the cable and achieving a certain temperature barrier. The second fireproof layer 203 then... To prevent high temperatures from affecting the inside of the cable, the first fireproof layer 201 absorbs heat, and the space between the third shielding layer 105 and the first wrapping tape 103 provides an air medium to disperse heat. When the internal cable conductor is energized, the heat dissipation support 202 contacts the second fireproof layer 203 and the first fireproof layer 201 to form an arc-shaped hole, creating an air layer between the second fireproof layer 203 and the first fireproof layer 201. This adds an air medium to the temperature conduction process to achieve cooling. At the same time, the arc-shaped hole formed by the heat dissipation support 202 can also improve the cable's impact resistance. Through the temperature attenuation of the layers, the final temperature will be greatly reduced.

[0030] In summary, the first fireproof layer 201 and the second fireproof layer 203 form a multi-layer fireproof structure, which can increase the fire resistance of the cable. The space structure formed between the heat dissipation support 202 and the first fireproof layer 201 and the second fireproof layer 203 not only increases the heat dissipation capacity of the cable, but also improves the impact resistance of the cable.

[0031] Example 2

[0032] Reference Figures 1-2 This is the second embodiment of the present invention, which includes a second wrapping tape 102a tightly attached to the inner wall of the first shielding layer 102.

[0033] The second wrapping tape 102a is made of polyester tape. The polyester tape is used to prevent the braided copper wires of the first shielding layer 102 from piercing the insulation layer and damaging the cable conductor, as well as to prevent the core of the cable from becoming loose.

[0034] Furthermore, the bracket 101 divides the internal space of the first packing strap 103 into multiple spaces, and the first shielding layer 102 is provided in each of the multiple spaces.

[0035] Among them, the support 101 is a hollow structure that mainly serves to dissipate heat. The specific shape of the support 101 can be changed by dividing the first wrapping tape 103 into a certain number of spaces, i.e., setting up a certain number of first shielding layers 102.

[0036] Furthermore, the heat dissipation support 202 has an arc-shaped cross-section.

[0037] Among them, when the cross-section of the heat dissipation support 202 is of other shapes, the improvement in the cable's impact resistance is less than when the cross-section of the heat dissipation support 202 is arc-shaped. Moreover, the arc shape requires less material compared to other shapes, while also creating a larger space to allow more air medium during heat conduction.

[0038] Furthermore, the inner wall of the second packing tape 102a is provided with a first insulating layer 106.

[0039] Multiple first insulation layers 106 may be provided close to the inner wall of the second wrapping tape 102a. The number of first insulation layers 106 can be increased or decreased according to the actual use. The function of the first insulation layer 106 is to protect the internal cable conductor.

[0040] Furthermore, the space enclosed by the second shielding layer 104 is located within the space enclosed by the first wrapping tape 103 and the third shielding layer 105, and the second shielding layer 104 is provided with at least one.

[0041] The second shielding layer 104 is a closed cylindrical structure. The cross-sectional shape of the second shielding layer 104 can be circular, elliptical, etc. The second shielding layer 104 is a copper wire braided shield. The cross-section of the space enclosed by the first wrapping tape 103 and the third shielding layer 105 is a ring. The second shielding layer 104 is located within the ring space enclosed by the first wrapping tape 103 and the third shielding layer 105. The number of second shielding layers 104 can be increased or decreased according to the actual application.

[0042] Furthermore, a third wrapping tape 104a is provided tightly against the inner wall of the second shielding layer 104.

[0043] The third wrapping tape 104a is made of the same material as the second wrapping tape 102a, which is polyester tape. The function of the third wrapping tape 104a is to prevent the copper wire braid of the second shielding layer 104 from piercing the insulation layer and causing damage to the cable conductor, and to prevent the cable core from becoming loose.

[0044] Furthermore, the inner wall of the third wrapping tape 104a is provided with a second insulating layer 104b.

[0045] The second insulation layer 104b is located within the space enclosed by the third wrapping tape 104a. The main function of the second insulation layer 104b is to protect the cable conductor. The number of second insulation layers 104b can be increased or decreased according to the actual usage.

[0046] Furthermore, the first shielding layer 102 is made of the same material as the second shielding layer 104 and the third shielding layer 105, the first insulating layer 106 is made of the same material as the second insulating layer 104b, and the first wrapping tape 103 is made of the same material as the second wrapping tape 102a and the third wrapping tape 104a.

[0047] The first shielding layer 102, the second shielding layer 104, and the third shielding layer 105 are all made of copper wire braiding, and the first wrapping tape 103, the second wrapping tape 102a, and the third wrapping tape 104a are all made of polyester tape.

[0048] In use, the internal support 101 supports the internal first wrapping tape 103 while dividing the internal space of the first wrapping tape 103 into several parts. The number of parts divided by the support 101 is increased or decreased according to the user's usage. The support 101 has a hollow structure for heat dissipation. Each space in the first wrapping tape 103 divided by the support 101 is equipped with a first shielding layer 102. When the external temperature rises or an open flame is present, the first sheath 204 acts as the first layer of fire protection, preventing the open flame from directly contacting the inside of the cable and achieving a certain temperature barrier. The second fireproof layer 203 then... To prevent high temperatures from affecting the inside of the cable, the first fireproof layer 201 absorbs heat, and the space between the third shielding layer 105 and the first wrapping tape 103 provides an air medium to disperse heat. When the internal cable conductor is energized, the heat dissipation support 202 contacts the second fireproof layer 203 and the first fireproof layer 201 to form an arc-shaped hole, creating an air layer between the second fireproof layer 203 and the first fireproof layer 201. This adds an air medium to the temperature conduction process to achieve cooling. At the same time, the arc-shaped hole formed by the heat dissipation support 202 can also improve the cable's impact resistance. Through the temperature attenuation of the layers, the final temperature will be greatly reduced.

[0049] In summary, the first fireproof layer 201 and the second fireproof layer 203 form a multi-layer fireproof structure, which can increase the fire resistance of the cable. The space formed between the heat dissipation support 202 and the first fireproof layer 201 and the second fireproof layer 203 not only increases the heat dissipation capacity of the cable, but also improves the impact resistance of the cable.

[0050] Example 3

[0051] Reference Figures 1-2 This is the third embodiment of the present invention. This embodiment further provides a flame-retardant computer cable 300, which includes a protective structure and a first conductor 301 disposed on the inner wall of the first insulation layer 106 and a second conductor 302 disposed on the inner wall of the second insulation layer 104b.

[0052] The first conductor 301 and the second conductor 302 are solid or twisted structures.

[0053] In use, when the first conductor 301 and the second conductor 302 are located inside the first insulation layer 106 and the second insulation layer 104b respectively, the first conductor 301 and the second conductor 302 are separated by the first shielding layer 102 and the second shielding layer 104b, minimizing their mutual interference. Separating the two different cable conductor structures (first conductor 301 and second conductor 302) also facilitates wiring. In actual use, the internal support 101 supports the internal first wrapping tape 103 while dividing the space inside the first wrapping tape 103 into several parts. The number of parts divided by the support 101 can be increased or decreased according to the user's needs. The support 101 has a hollow structure for heat dissipation. Each space in the first wrapping tape 103 divided by the support 101 is equipped with a first shielding layer 10. 2. When the external temperature rises or an open flame is present, the first sheath 204 acts as the first layer of fire protection, preventing the open flame from directly contacting the inside of the cable and providing a certain degree of temperature barrier. The second fireproof layer 203 further blocks the impact of high temperature on the inside of the cable. After the first fireproof layer 201 absorbs heat, there is a space between the third shielding layer 105 and the first wrapping tape 103, which also provides an air medium to disperse heat. When the internal cable conductor is energized, the heat dissipation support 202 contacts the second fireproof layer 203 and the first fireproof layer 201 to form an arc-shaped hole, forming an air layer between the second fireproof layer 203 and the first fireproof layer 201. This adds an air medium to the temperature conduction process to achieve cooling. At the same time, the arc-shaped hole formed by the heat dissipation support 202 can also improve the cable's impact resistance. Through the temperature attenuation of the layers, the final temperature will be greatly reduced.

[0054] In summary, the first fireproof layer 201 and the second fireproof layer 203 inside the flame-retardant computer cable 300 of this utility model form a multi-layer fireproof structure, which can increase the fire resistance of the cable. The space formed between the heat dissipation support 202 and the first fireproof layer 201 and the second fireproof layer 203 not only increases the heat dissipation capacity of the cable, but also improves the impact resistance of the cable. The layered cable shielding structure makes the anti-interference performance better and the wiring more convenient.
