BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 The utility model relates to a combined cable used in an integrated wiring system. DETAILED DESCRIPTION

[0016] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0017] like Figure 1As shown, the combined cable for use in an integrated wiring system described in the utility model comprises: a Category 5e data unit 1, a first control unit 2, a second control unit 3 and a serial port line 4. The Category 5e data unit 1, the first control unit 2 and the second control unit 3 are twisted into a cable with the serial port line 4 as the center. Placing the serial port line 4 in the center can make the serial port line 4 closer to the reference level of the signal, which helps to maintain the stability of the signal and can reduce the influence of external electromagnetic interference on the signal transmission of the serial port line 4 to a certain extent. Moreover, the Category 5e data units 1, the first control unit 2 and the second control unit 3 around it can provide good mechanical protection for it and will not be directly affected by external forces, thereby reducing the risk of damage. The two Category 5e data units 1 are arranged on both sides of the serial port line 4, which can reduce the crosstalk between the two Category 5e data units 1 and ensure the stability and reliability of the signal transmission of the Category 5e data units 1. The two second control units 3 are located on one side of the two Category 5e data units 1, and the other two second control units 3 and one first control unit 2 are located on the other side of the two Category 5e data units 1. The four second control units Arranging them in pairs can prevent the four second control units 3 from being too concentrated and causing signal crosstalk between each other. Cotton ropes 5 are filled in the external gaps of the adjacent Category 5e data units 1, the first control unit 2 and the second control unit 3 as filling ropes. Since the combined cable needs to be laid in the wall, the wall is easily damp due to the influence of the external environment. The water vapor in the damp wall is easy to penetrate into the combined cable. Although the amount of water vapor is small, it is also easy to affect the signal transmission performance of the combined cable. The cotton ropes 5 filled in the external gaps of each unit can prevent the small amount of water vapor from penetrating into the combined cable. Water vapor is absorbed to reduce the impact on the combined cable. PE monofilament 6 is filled in the gap between the serial port line 4 and the Category 5e data unit 1, the first control unit 2 and the second control unit 3 as a filling rope. The PE monofilament 6 has high wear resistance and tensile resistance. When the combined cable is bent during the laying process, the friction surface between each unit and the serial port line 4 can be reduced, and the tensile strength of the serial port line 4 can be correspondingly improved. Filling the cotton rope 5 and the PE monofilament 6 inside and outside respectively can not only ensure the roundness of the combined cable, but also prevent the units from being excessively concentrated together.A first tape layer 7 is wrapped around the cabled Category 5e data unit 1, the first control unit 2 and the second control unit 3. The first tape layer 7 fastens the cabled Category 5e data unit 1, the first control unit 2 and the second control unit 3 to the serial port line 4 to prevent them from loosening. A tinned copper wire braided layer 8 is woven on the first tape layer 7. The braiding density of the tinned copper wire braided layer 8 is ≥90%. A first aluminum-plastic composite tape 81 is wrapped around the tinned copper wire braided layer 8. The metal surface of the first aluminum-plastic composite tape 81 is in contact with the tinned copper wire braided layer 8. The overlap rate of the first aluminum-plastic composite tape 81 is greater than 10%. The double shielding structure combining the tinned copper wire braided layer 8 and the first aluminum-plastic composite tape 81 can improve the anti-interference performance of the combined cable and ensure the stable transmission of the signal. Moreover, because the shielding performance of the tinned copper wire braided layer 8 with a braiding density ≥90% is better, it can be The overlap rate of the first aluminum-plastic composite tape 81 is correspondingly reduced, so that when the first aluminum-plastic composite tape 81 has a certain shielding effect, the flexibility of the first aluminum-plastic composite tape 81 can be improved due to the smaller overlap rate, thereby improving the flexibility of the combined cable. A second wrapping layer 9 is wrapped on the first aluminum-plastic composite tape 81, and the wrapping direction of the second wrapping layer 9 is opposite to the wrapping direction of the first aluminum-plastic composite tape 81, which can reduce the stress concentration inside the combined cable, thereby enhancing the overall stability of the combined cable. A flame retardant layer 10 and a sheath 101 are sequentially extruded on the second wrapping layer 9. The sheath 101 cooperates with the flame retardant layer 10 to improve the protective performance of the combined cable. When the flame retardant layer 10 and the sheath 101 are co-extruded, it is necessary to ensure that the flame retardant layer 10 is coaxial with the sheath 101 to ensure the uniformity of the overall structure of the combined cable, thereby ensuring the mechanical strength and electrical performance of the combined cable.

[0018] The serial port line 4 is formed by twisting two first insulating core wires 41, and the two first insulating core wires 41 are a transmitting line and a receiving line respectively. Since the double-layer shielding layer composed of the tinned copper wire braided layer 8 and the first aluminum-plastic composite tape 81 in the combined cable can play a grounding role, there is no need to set an additional ground wire in the serial port line 4, which reduces the production cost and improves the flexibility of the serial port line 4. Since the serial port line 4 is located in the center, the mechanical stress on the combined cable when bending can be reduced, which is more convenient for the bending of the combined cable and more convenient when laying. The twisting pitch of the serial port line 4 is different from the cabling pitch to ensure the structural stability of the combined cable.

[0019] The Category 5e data unit 1 comprises: two second insulating core wires 11, the two second insulating core wires 11 are twisted into a cable, the twisting pitch of the two Category 5e data units 1 is different from the twisting pitch of the serial port line 4, which can reduce the signal crosstalk between the Category 5e data unit 1 and the serial port line 4, and the twisting gap is filled with a polypropylene bulked yarn 12, which can not only ensure the roundness of the Category 5e data unit 1, but also ensure the electrical performance of the Category 5e data unit 1 due to its good insulation. A drainage line 13 is wrapped around the two second insulating core wires 11 in the cable, and a second aluminum-plastic composite tape 14 is wrapped around the two second insulating core wires 11 in the cable, the overlap rate of the second aluminum-plastic composite tape 14 is greater than 50%, and the metal surface of the second aluminum-plastic composite tape 14 faces inward and overlaps with the drainage line. The wire 13 is in contact with the second aluminum-plastic composite tape 14, and the high overlap rate of the second aluminum-plastic composite tape 14 can improve the shielding effect of the second aluminum-plastic composite tape 14. The second aluminum-plastic composite tape 14 combined with the drainage wire 13 further improves the shielding effect, and can reduce the mutual crosstalk, external interference and return loss between the loops, thereby improving the signal transmission efficiency and quality of the super five data unit 1. A third wrapping layer 15 is wrapped on the second aluminum-plastic composite tape 14, and the wrapping direction of the third wrapping layer 15 is opposite to the wrapping direction of the second aluminum-plastic composite tape 14, thereby reducing the internal stress concentration of the super five data unit 1, thereby enhancing the overall stability of the super five data unit 1. The two super five data units 1 have different twisting pitches, which can eliminate the system coupling between the two, reduce interference, and improve their respective response speeds and control efficiency.

[0020] The first control unit 2 includes: seven third insulating core wires 21, the seven third insulating core wires 21 are twisted into a cable in a 1+6 structure, the twisting pitch of the first control unit 2 is different from the twisting pitch of the serial port line 4 and the super five data unit 1, reducing the signal crosstalk between the first control unit 2 and the super five data unit 1 and the serial port line 4, and the conductor cross-sectional area of ​​the third insulating core wire 21 is 0.14mm 2 , can be connected to information sockets, distribution frames, optical fiber connectors and other devices with low transmission current in the integrated wiring system. The second control unit 3 includes: four single insulated core wires, the conductor cross-sectional area of ​​the single insulated core wire is 1mm 2 It can be connected to devices with large transmission current, such as transfer points, network cabinets, and electrical protection equipment in the integrated wiring system. In this way, the corresponding control unit can be selected according to the different current requirements of the equipment. There will be no situation where large-diameter insulating core wires are used on small-current equipment, resulting in the large-diameter insulating core wires having too low resistance and affecting the efficiency of the electrical system. There will also be no situation where small-diameter insulating core wires are used on large-current equipment, resulting in the inability to carry the normal current of the equipment and causing the small-diameter insulating core wires to be overloaded and short-circuited.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modification or equivalent replacement that does not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
