Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a cable for long-distance transmission of image signals from a camera. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals, typically consisting of several or groups of wires. It is usually a rope-like cable made up of several or groups of wires (each group containing at least two wires) twisted together. Cameras require specific cables for transmitting image signals.

[0003] Existing camera cables typically only transmit image signals during signal transmission, and there may be issues such as signal attenuation and eavesdropping during long-distance transmission of image signals.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a cable for long-distance transmission of image signals from a camera. Utility Model Content

[0005] The purpose of this invention is to provide a cable for long-distance transmission of image signals from a camera, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable for long-distance transmission of image signals from a camera, comprising an outer jacket, a metallized PET polyester film, and an STP network cable assembly. A metal foil shielding layer is disposed inside the outer jacket, and a metallized PET polyester film is disposed inside the metal foil shielding layer. Two STP network cable assemblies are disposed inside the metallized PET polyester film. Each STP network cable assembly includes a Pet insulation layer, an Al-Mylar polyester film layer, and an STP cable. An Al-Mylar polyester film layer is disposed inside the Pet insulation layer, and an STP cable is disposed inside the Al-Mylar polyester film layer. A 7C wire is disposed on one side of each of the two STP network cable assemblies, and seven MCC cables are disposed on the other side of each of the two STP network cable assemblies. An insulating filler layer is filled between the STP network cable assembly, the 7C wire, the MCC cable, and the metallized PET polyester film.

[0007] Furthermore, both the metal foil shielding layer and the metallized PET polyester film have a spiral structure.

[0008] Furthermore, the STP cable, 7C wire, and MCC cable are all AWG grade, and the 7C wire is specifically a copper-plated conductor.

[0009] Furthermore, an anti-rodent component is fixed to the outside of the outer jacket, and the anti-rodent component includes an anti-abrasion strip. The anti-abrasion strip is uniformly fixed to the outside of the outer jacket in a circular radial pattern, and the surface of the anti-abrasion strip is coated with an anti-rodent coating containing capsaicin.

[0010] Furthermore, the anti-rat bite component also includes reinforcing plates and conical spikes. The anti-abrasion strip has two reinforcing plates embedded inside, and a conical spike is provided in the middle between the reinforcing plates.

[0011] Furthermore, the outer surface of the outer jacket is coated with an anti-corrosion coating.

[0012] This utility model provides a cable for long-distance transmission of image signals from a camera, which has the following features:

[0013] Beneficial effects:

[0014] This utility model is equipped with a shielding layer and several wires. The metal foil shielding layer and the metallized PET polyester film are both woven in a spiral structure on the outside of the insulation filling layer of the cable to wrap it, forming multiple shielding layers that can isolate electromagnetic interference. The MCC cable can transmit radio frequency signals or high-definition camera signals for long-distance transmission of image signals. The STP network cable assembly is a shielded wire that has the advantages of reducing signal attenuation and preventing information from being eavesdropped. The MCC cable, together with the 7C wire, has the dual functions of power supply and transmission of image signals.

[0015] This utility model is equipped with an anti-rat bite component. The anti-corrosion coating can improve the anti-corrosion effect of the outer layer, the reinforcing sheet can enhance the structural strength of the anti-wear strip, and several anti-wear strips can play an anti-wear role. Furthermore, the surface of the anti-wear strip is coated with an anti-rat bite coating containing capsaicin to prevent rat bites.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1 and Figure 3 As shown, a cable for long-distance transmission of image signals from a camera includes an outer jacket 1, a metallized PET polyester film 3, and an STP network cable assembly 4. A metal foil shielding layer 2 is disposed inside the outer jacket 1, and a metallized PET polyester film 3 is disposed inside the metal foil shielding layer 2. Both the metal foil shielding layer 2 and the metallized PET polyester film 3 have a spiral structure. An insulating filler layer 7 fills the space between the STP network cable assembly 4, the 7C wire 5, the MCC cable 6, and the metallized PET polyester film 3. The metal foil shielding layer 2 and the metallized PET polyester film 3 are spirally woven around the outside of the insulating filler layer 7 of the cable, forming multiple shielding layers to isolate electromagnetic interference. The metallized PET polyester film 3 is a high-performance PET film with high voltage resistance and good insulation, a unique metallic texture, and excellent mechanical properties, chemical stability, and weather resistance. The insulating filler layer 7 forms an insulator to provide insulation.

[0023] like Figures 1-2As shown, two STP cable assemblies 4 are disposed inside the metallized PET polyester film 3. Each STP cable assembly 4 includes a Pet insulating layer 401, an Al-Mylar polyester film layer 402, and an STP cable 403. An Al-Mylar polyester film layer 402 is disposed inside the Pet insulating layer 401, and an STP cable 403 is disposed inside the Al-Mylar polyester film layer 402. A 7C wire 5 is disposed on one side of each of the two STP cable assemblies 4, and seven MCC cables 6 are disposed on the other side. The STP cable 403, 7C wire 5, and MCC cable 6 are also present. All cables 6 are 38AWG in size, and the 7C wire 5 is specifically a copper-plated conductor. The MCC cable 6 can transmit radio frequency signals or high-definition camera signals for long-distance image signal transmission. The six MCC cables 6 are independent and do not interfere with each other. The STP network cable assembly 4 is a shielded conductor, which has the advantages of reducing signal attenuation and preventing information from being eavesdropped on. The Pet insulation layer 401 can effectively insulate, and the Al-Mylar polyester film layer 402 is a shielding layer. It also has the characteristics of high strength, high gloss, transparency, wear resistance, corrosion resistance and high temperature resistance, which can avoid mutual interference with multiple conductors inside the cable.

[0024] like Figures 3-4 As shown, an anti-rat bite component 8 is fixed to the outside of the outer layer 1. The anti-rat bite component 8 includes an anti-abrasion strip 801, which is uniformly fixed to the outside of the outer layer 1 in a circular radial pattern. The surface of the anti-abrasion strip 801 is coated with an anti-rat bite coating containing capsaicin. The anti-rat bite component 8 also includes reinforcing plates 802 and conical spikes 803. Two reinforcing plates 802 are embedded inside the anti-abrasion strip 801, and a conical spike 803 is provided in the middle between the reinforcing plates 802. The outer surface of the outer layer 1 is coated with an anti-corrosion coating 9. The anti-corrosion coating 9 can improve the anti-corrosion effect of the outer layer 1. The reinforcing plates 802 can enhance the structural strength of the anti-abrasion strip 801. Several anti-abrasion strips 801 can play a role in preventing wear. The anti-rat bite coating containing capsaicin on the surface of the anti-abrasion strip 801 can prevent rat bites. If a mouse bites through the anti-abrasion strip 801, the small conical spikes 803 embedded in it will protrude and pierce the mouse's mouth, further preventing rat bites.

[0025] In summary, as Figures 1-4As shown, the cable for long-distance image signal transmission of this camera, when in use, the STP network cable assembly 4, 7C wire 5, and MCC cable 6 are integrated into one cable, which can connect to the camera. The insulating filler layer 7 forms an insulator to provide insulation. The metal foil shielding layer 2 and the metallized PET polyester film 3 are both spirally woven around the outside of the insulating filler layer 7 of the cable, forming multiple shielding layers to isolate electromagnetic interference. The metallized PET polyester film 3 is a high-performance PET film with high voltage resistance and good insulation, a unique metallic texture, and excellent mechanical properties, chemical stability, and weather resistance. During use, the MCC cable 6 can transmit radio frequency signals or high-definition camera signals for long-distance image signal transmission. The six MCC cables 6 are independent and do not interfere with each other. The STP network cable assembly 4 is a shielded wire with the advantages of reducing signal attenuation and preventing information from being eavesdropped. The Pet insulation layer 401 can effectively insulate, and the Al-Mylar polyester film layer 402 is the shielding layer. When in use, the anti-corrosion coating 9 can improve the anti-corrosion effect of the outer jacket layer 1. The reinforcing piece 802 can enhance the structural strength of the anti-wear strip 801, so that several anti-wear strips 801 can play an anti-wear role. In addition, the surface of the anti-wear strip 801 is coated with a rodent-proof coating containing capsaicin to prevent rodent bites. If a mouse bites through the anti-wear strip 801, its embedded small conical barb 803 protrudes and can pierce the mouse's mouth, further preventing rodent bites. This completes the use process of the cable for long-distance transmission of image signals of the camera.
