Examples
Referring to fig. 1, the present utility model provides a technical solution:
the three-piece combined cable consists of a three-core power line 1, a two-core sound line 2 and a shielding twisted pair 3, wherein the three-core power line 1, the two-core sound line 2 and the shielding twisted pair 3 are connected in a triangular shape through a connecting part 5.
In this embodiment, the material of the connection portion 5 is the same as that of the cable insulating layer 7, and the connection portion 5 is in hot-melt connection with the three-core power cord 1, the two-core acoustic cord 2 and the shielded twisted pair 3. Three-core power cords are a common power cord, which is typically composed of three conductors, fire (Live), neutral (Neutral) and Ground (Ground), respectively. It is mainly used for connecting the power supply of a power source to an electrical device. The live and neutral wires carry ac power and the ground wire is used for safe grounding to ensure electrical safety during use of the device. Three-core power cords are a common power cord, which is typically composed of three conductors, fire (Live), neutral (Neutral) and Ground (Ground), respectively. It is mainly used for connecting the power supply of a power source to an electrical device. The live and neutral wires carry ac power and the ground wire is used for safe grounding to ensure electrical safety during use of the device. A shielded twisted pair is a cable having a metallic shield layer for providing electromagnetic shielding protection. It consists of a plurality of pairs of insulated twisted pairs, each pair having its own metallic shield. Shielded twisted pair wires are mainly used in applications where it is desirable to reduce the effects of external electromagnetic interference, such as data communications, industrial automation, and audio-video transmission.
In this embodiment, a tensile aluminum stranded wire 6 is disposed at the center of the connection portion 5 to enhance the tensile strength of the cable. The tensile aluminum stranded wire adopts an additional reinforced design, so that the tensile aluminum stranded wire has higher tensile strength. This enables it to withstand greater tension and stress in the power transmission, reducing the risk of cable breakage or damage. The tensile strength of the tensile aluminum strands is generally higher than that of copper conductor cables, such as up to 80-110 newtons per square millimeter (N/mm) 2 ) Whereas copper conductor cables are typically 70-90N/mm 2 . The tensile aluminum stranded wire has a lighter weight than the conventional copper conductor cable. Because of the lower density of aluminum, the use of tensile aluminum strands can reduce the overall weight of the cable. The tensile aluminum stranded wires are relatively light and have a weight of about 30-40% of the weight of the copper conductor cable per meter.
In this embodiment, the three parts of the three-core power cord 1, the two-core acoustic cord 2 and the shielding twisted pair 3 are all provided with a shielding layer 4 for shielding the interference signal generated in the use process. The shielding layer is a cable or a part of a cable for providing electromagnetic shielding protection. The device can effectively reduce the interference of external electromagnetic fields and protect the quality and reliability of signal transmission. The shielding layer may provide a refractive loss (Shielding Effectiveness, SE) of up to 60-80dB or more at a frequency of 10MHz, i.e. attenuating the external interfering signal by 60-80dB. The shielding layer may reduce crosstalk between signals. When a plurality of cables or wires are densely arranged together, signal crosstalk may occur therebetween, resulting in mutual interference, distortion or loss of signals. The shielding layer can effectively reduce the effects of crosstalk by providing physical isolation and electromagnetic shielding. Using shielded cables in a high density wiring environment can reduce crosstalk to below 10% of unshielded cables.
In this embodiment, the two-core acoustic wire 2 is made of a copper-silver alloy material. The acoustic line is made of copper-silver alloy materials, and has the advantages of improving conductivity, improving sound transmission quality, improving oxidation resistance and corrosion resistance, reducing signal distortion and the like. Copper-silver alloys have higher electrical conductivity than pure copper. The conductivity of copper is 59.6MS/m (megasiemens/m), while the conductivity of copper-silver alloy can reach 65-70MS/m. The copper-silver alloy added with the silver element can effectively prevent oxidation and corrosion and prolong the service life of the sound wire. The copper-silver alloy added with the silver element can effectively prevent oxidation and corrosion and prolong the service life of the sound wire.
By means of triangular arrangement, construction difficulty in the construction pipe penetrating process is effectively reduced, and construction efficiency is improved; the tensile aluminum stranded wire is arranged in the center of the connecting part, so that the tensile property of the cable is enhanced, and the situation that the wire core is pulled and broken in construction is effectively solved; by changing the cable combination, the cable combination can adapt to the requirements of the current construction project, and the power line is used for transmitting electric energy; the sound wire is used for transmitting sound signals; the twisted pair is used for transmitting the video monitoring signal. The three are organically combined, so that the times of cable laying are reduced, and the construction efficiency is improved.
The foregoing has shown and described the basic principles and main features of the present utility model and the advantages of the present utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, which is defined in the appended claims.
