Description

Technical Field

[0001] The invention relates to the field of cables, and in particular to a highly flame-retardant, torsion-resistant and wear-resistant integrated cable for access control systems. Background Art

[0002] For modern buildings, the intelligent access control system is like the nerves in the body. In recent years, the design and application of the access control system have received widespread attention. It uses a series of high-quality standard materials and a modular combination to integrate voice, data, image and some control signal systems with a unified transmission medium. After unified planning and design, it is integrated into a set of standard wiring systems, which organically connects the three subsystems of modern buildings and provides a physical medium for the system integration of modern buildings. However, the most time-consuming part of installing the access control system is wiring. Each electric shock device, magnetic lock and document reader must be hard-wired to the access control unit (ACU) usually installed in the IT room.

[0003] Disadvantages of traditional access control cable wiring:

[0004] (1) It is relatively troublesome to wire multiple single cables according to the different uses of each cable. It is easy to get confused during wiring, resulting in wiring errors;

[0005] (2) Low-voltage wires are not separated from high-voltage wires. All cables used in the access control system are low-voltage wires. They need to be completely separated from high-voltage wires to prevent induced voltage or interference, which would prevent the access control cables from transmitting signals normally. In addition, after the wiring is completed, there is signal interference between the cables during use, resulting in blurred video and slow card swiping response during face recognition.

[0006] (3) In the event of a fire, ordinary cables can easily become flammable, making the fire difficult to control and producing a large amount of smoke that can suffocate people. Summary of the invention

[0007] In view of the above problems, the present invention overcomes at least one disadvantage and proposes a highly flame-retardant, torsion-resistant and wear-resistant integrated cable for access control system.

[0008] The technical solution adopted by the present invention is as follows:

[0009] A highly flame-retardant, torsion-resistant and wear-resistant integrated cable for access control system, comprising four cables, a fire extinguishing strip, a winding cloth layer and a total sheath;

[0010] The four cables are respectively a communication cable, a sensor cable, a power cable, and a linkage control cable. The four cables are against each other, the wrapping cloth is wrapped around the outside of the four cables, the fire extinguishing strip is located in the space surrounded by the wrapping cloth layer, and the general sheath is located outside the wrapping cloth layer;

[0011] All four cables have outer sheaths, and the colors of the outer sheaths of different cables are different;

[0012] The inner side of the outer sheath of the communication cable has an aluminum foil shielding layer, and the communication cable is used to connect the access control card reader and the access control controller;

[0013] The sensor cable is used to connect various sensors in the access control system with the access control controller;

[0014] The power cable is used to connect the power adapter or power distributor to the power input port of the access control system;

[0015] The linkage control cable is used to connect the access controller and the door lock;

[0016] The fire extinguishing strip includes perfluorohexanone microcapsules.

[0017] The integrated cable of the present application has four cables for different purposes under one general sheath, which effectively saves the time for preparation, setting, pulling and terminating, and the outer sheaths of different cables are of different colors, which is easy to distinguish to prevent wiring errors and reduce wiring costs. The communication cable adopts an aluminum foil shielding layer to shield external interference and enhance the signal stability during signal transmission, so that the signal can be output stably during the operation of the access control system, and prevent signal interruption and jamming. The fire extinguishing strip has perfluorohexanone microcapsules, which can soften and rupture at around 100°C or when exposed to open flames, thereby releasing perfluorohexanone, automatically triggering the fire extinguishing function, and effectively improving the flame retardant ability.

[0018] In actual application, the perfluorohexanone microcapsules can adopt various types of perfluorohexanone microcapsule structures in the prior art.

[0019] In actual application, various types of sensors may include door magnetic sensors, infrared sensors, and so on.

[0020] In one embodiment of the present invention, the fire extinguishing strip includes a plurality of fire extinguishing units arranged in sequence and spaced apart from each other, each fire extinguishing unit is connected by a connecting rope, and the fire extinguishing unit includes:

[0021] A limit block is stuck between two adjacent cables, and the connecting rope is fixed to the limit block;

[0022] A fire extinguishing plate is fixed on the limiting block, and the fire extinguishing plate has the perfluorohexanone microcapsules.

[0023] The limit block is used to facilitate limiting between two cables. The limit block is used to fix the fire extinguishing board. The fire extinguishing boards arranged at intervals can reduce costs. In actual use, the ratio of the length of the fire extinguishing board to the length of the connecting rope is 1: (5~10).

[0024] In one embodiment of the present invention, the limit block has three surfaces arranged in sequence on its circumference, two of which are arcuate surfaces and the third is a straight surface. The two arcuate surfaces of the limit block are respectively in contact with the outer sheaths of the two cables, and the straight surface of the limit block is fixed to the fire extinguishing plate.

[0025] In one embodiment of the present invention, the arc surface has glue on it, and the arc surface is fixed to the outer sheath of the corresponding cable by the glue.

[0026] In one embodiment of the present invention, the four cables are cabled using a back-twist process.

[0027] The traditional access control system cables are easily twisted and bent during wiring, especially when passing through pipes, due to the torque of the single wire, making it difficult to operate. The present invention uses a back-twisting process when cabling the four cables, so that there is no stress during the wiring process, and the pipe and wiring are smooth. The present invention uses a "back-twisting" cabling process for the four cables to make them stress-free during the wiring process, and the pipe and wiring are smooth, thereby improving wiring efficiency and saving time.

[0028] In one embodiment of the present invention, a nylon sheath is further included, and the nylon sheath is arranged on the outside of the total sheath.

[0029] Traditional access control cables use ordinary PVC material as the outermost protective layer. The friction coefficient of PVC material as a sheath is 0.05~0.15, which is relatively easy to be worn out during the wiring and pipe-threading process. The present application squeezes a layer of nylon sheath on the outermost layer of the integrated cable to make the cable as a whole wear-resistant and durable. In addition, nylon material is resistant to high temperatures, chemical corrosion, and has good insulation properties. It can effectively prevent the leakage of current and improve the safety and electrical efficiency of wires. In particular, nylon cables are lighter than traditional metal wires and have a certain degree of flexibility, which is easy to install and maintain, especially in situations where tortuous wiring is required. The friction coefficient of the nylon sheath of the present application is 0.35~0.5. It is wear-resistant and torsion-resistant during the wiring and pipe-threading process, so that the integrated cable body is not damaged by the outside world.

[0030] In one embodiment of the present invention, the communication cable has six conductors, and two conductors diagonally opposite to each other are twisted into a pair of wires.

[0031] The communication cable is configured in this way to form a stable structure during the cabling process, which enhances signal stability during signal transmission.

[0032] In one embodiment of the present invention, the overall sheath is made of flame retardant material.

[0033] Ordinary cables are easy to ignite and produce a large amount of toxic smoke in the event of a fire, which can cause suffocation. In addition, during the combustion process, there are dripping objects that cause other objects to burn and increase the fire. In actual use, the overall sheath can use materials that meet the flame retardant grade of "CMP" in the US UL444 laboratory standard.

[0034] In one embodiment of the present invention, the thickness of the aluminum foil shielding layer is 0.006 μm to 0.012 μm.

[0035] In one embodiment of the present invention, a tear cord is further included, and the tear cord is located in the space surrounded by the wrapped cloth layer.

[0036] The beneficial effects of the present invention are as follows: the integrated cable of the present application has four cables for different purposes under one general sheath, which effectively saves the time for preparation, setting, pulling and terminating, and the outer sheaths of different cables are of different colors, which is easy to distinguish to prevent wiring errors and reduce wiring costs. The communication cable adopts an aluminum foil shielding layer to shield external interference, enhance the signal stability during signal transmission, enable stable signal output during the operation of the access control system, and prevent signal interruption and jamming. The fire extinguishing strip has perfluorohexanone microcapsules, which can soften and rupture at around 100°C or when exposed to open flames, thereby releasing perfluorohexanone, automatically triggering the fire extinguishing function, and effectively improving the flame retardant ability.

The fire extinguishing strip 5 has perfluorohexanone microcapsules, which can soften and rupture at around 100°C or when encountering an open flame, thereby releasing perfluorohexanone, automatically triggering the fire extinguishing function, and effectively improving the flame retardant ability.

[0055] In actual application, the perfluorohexanone microcapsules can adopt various types of perfluorohexanone microcapsule structures in the prior art.

[0056] In actual application, various types of sensors may include door magnetic sensors, infrared sensors, and so on.

[0057] like Figure 3 As shown, in this embodiment, the fire extinguishing strip 5 includes a plurality of fire extinguishing units 51 arranged in sequence and spaced apart from each other, and each fire extinguishing unit 51 is connected by a connecting rope 52. The fire extinguishing unit 51 includes:

[0058] The limit block 511 is stuck between two adjacent cables, and the connecting rope 52 is fixed to the limit block 511;

[0059] The fire extinguishing plate 512 is fixed on the limiting block 511, and the fire extinguishing plate 512 has perfluorohexanone microcapsules.

[0060] The limit block 511 is used to facilitate limiting between two cables. The limit block 511 is used to fix the fire extinguishing plate 512. The fire extinguishing plates 512 arranged at intervals can reduce costs. In actual use, the ratio of the length of the fire extinguishing plate 512 to the length of the connecting rope 52 is 1: (5~10).

[0061] like Figure 1 As shown, in this embodiment, the circumference of the limit block 511 has three surfaces arranged in sequence, of which two are arcuate surfaces 5111 and the third is a straight surface 5112.

[0062] In actual use, preferably, the curved surface 5111 has glue, and the curved surface 5111 is fixed to the outer sheath 100 of the corresponding cable by the glue.

[0063] In this embodiment, the four cables are cabled using a back-twist process.

[0064] The traditional access control system cables are easily twisted and bent during wiring, especially when passing through pipes, due to the torque of the single wire, making it difficult to operate. The present invention uses a back-twisting process when cabling the four cables, so that there is no stress during the wiring process, and the pipe and wiring are smooth.

[0065] like Figure 1 and 2 As shown, in this embodiment, a nylon sheath 8 is also included, and the nylon sheath 8 is arranged on the outside of the main sheath 7.

[0066] Traditional access control cables use ordinary PVC materials as the outermost protective layer. The friction coefficient of PVC sheath is 0.05-0.15, which is relatively easy to be worn out during the wiring and pipe-threading process. The present application squeezes a layer of nylon sheath 8 on the outermost layer of the integrated cable to make the cable as a whole wear-resistant and durable. In addition, nylon material is resistant to high temperatures, chemical corrosion, and has good insulation properties. It can effectively prevent the leakage of current and improve the safety and electrical efficiency of wires. In particular, nylon cables are lighter than traditional metal wires and have a certain degree of flexibility, which is easy to install and maintain, especially in situations where tortuous wiring is required. The friction coefficient of the nylon sheath 8 of the present application is 0.35-0.5, which is wear-resistant and torsion-resistant during the wiring and pipe-threading process, so that the integrated cable body is not damaged by the outside world.

[0067] In actual use, preferably, the communication cable 1 has six conductors 11, and two conductors 11 diagonally opposite to each other are twisted into a pair of wires. The communication cable 1 is arranged in this way to form a stable structure during the cabling process, which enhances the signal stability during signal transmission.

[0068] In this embodiment, the main sheath 7 is made of flame retardant material. Ordinary cables are easy to ignite and produce a large amount of toxic smoke in the event of a fire, which can cause suffocation. In addition, during the combustion process, dripping materials may cause other objects to burn, which may increase the fire. In actual use, the main sheath 7 may be made of a material that meets the flame retardant grade of "CMP" in the US UL444 laboratory standard.

[0069] In this embodiment, the thickness of the aluminum foil shielding layer 12 is 0.006 μm to 0.012 μm.
