[0002] The function of a cable is to transmit electric power, and it can also transmit signals or realize the conversion of electromagnetic energy. It belongs to an electrical product. During the laying process of a cable, installers often use auxiliary tools that can fix the cable, such as wire clips, cable clamps, cable fixing heads, wire fixators, etc. These auxiliary tools can fix the cable, and then the auxiliary tools are installed on the wall. The fixation of the auxiliary tool means that the position of the cable is fixed, thus completing the installation of the cable.

[0003] However, using auxiliary tools to install cables may not be very convenient. And when the weather is hot, due to the effect of thermal expansion and contraction, the part of the cable not fixed by the auxiliary tool will become thicker, while the part of the cable fixed by the auxiliary tool remains unchanged due to the auxiliary tool. In this way, the surface of the cable is unevenly stressed and will be torn, and even the cable may leak electricity, posing certain safety hazards. Therefore, we need to design a multi-core wire and a cable protection device to solve the problem that the fixed part of the cable may be damaged due to the effect of thermal expansion and contraction. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multi-core wire and a cable protection device. By adding a protection mechanism at the fixed part of the cable and the wall to protect the cable and prevent it from being damaged and posing certain safety hazards. The protection mechanism installs a protection spring at the connection of two arc-shaped plates. When the cable expands and contracts due to hot weather, the arc-shaped plates will expand outwards due to the protection spring, so that the surface of the cable will not be unevenly stressed and the cable will not be torn. And because buckles and buckle locks are installed on the arc-shaped plates, the installation and disassembly of the cable become convenient.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A multi-core wire includes a housing. A circular bracket is installed at the center inside the housing. A first protective layer is installed outside the circular bracket. A second protective layer is installed inside the housing.

A plurality of wire cores are installed between the shielding layer and the first protective layer.

[0006] Preferably, partitions are installed between adjacent two wire cores, and both ends of the partitions are installed on the shielding layer and the first protective layer respectively.

[0013] 1. The present utility model mainly improves the service life of the multi-core wire by arranging a first protective layer, an insulating layer and a shielding layer inside the outer shell of the multi-core wire, making the multi-core wire more wear-resistant and durable. A partition is installed between adjacent wire cores to separate the multiple wire cores from each other, so that there is no interference between the wire cores. An annular bracket is installed inside the wire core to make the wire core fit more closely with the first protective layer, the insulating layer and the shielding layer, and it is not easy to cause damage to the wire core.

[0014] 2. The present utility model mainly adds a protection mechanism at the fixed part of the cable and the wall to protect the cable and prevent the cable from being damaged, which may cause certain potential safety hazards. The protection mechanism installs a protection spring at the connection of the two arc-shaped plates.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: a multi-core wire, including an outer shell 5, an annular bracket 4 is installed at the center inside the outer shell 5, a first protective layer 6 is installed outside the annular bracket 4, a second protective layer 3 is installed inside the outer shell 5, an insulating layer 7 is installed inside the second protective layer 3, a shielding layer 8 is installed inside the insulating layer 7, and a plurality of conductor cores 1 are installed between the shielding layer 8 and the first protective layer 6. By installing an annular bracket 4 inside the conductor core 1 and installing a second protective layer 3 outside the annular bracket 4, the conductor core 1 is more closely attached to the first protective layer 6, the insulating layer 7 and the shielding layer 8, and when being impacted, it is not easy to cause damage to the conductor core 1

[0022] Partition boards 2 are installed between adjacent two conductor cores 1, and both ends of the partition board 2 are respectively installed on the shielding layer 8 and the first protective layer 6. By setting the partition board 2, when one of the conductor cores 1 is damaged, it will not affect other conductor cores 1

[0023] A cable protection device includes a connecting plate 9. A frame 11 is installed on one side of the connecting plate 9. A protection mechanism is installed inside the frame 11. The protection mechanism includes four arc-shaped plates 15. One end of two of the arc-shaped plates 15 is hinged. First connecting pieces 13 are installed at the other ends of two of the arc-shaped plates 15. Protection springs 14 are installed at one ends of the two connecting pieces. A second connecting piece 19 is installed at one end of the two protection springs 14. One ends of the other two arc-shaped plates 15 are respectively installed on the two second connecting pieces 19, and a positioning mechanism is installed at the other ends of the other two arc-shaped plates 15.

[0024] The positioning mechanism includes a snap lock 16. The snap lock 16 is installed on the upper arc-shaped plate 15. A snap 17 is installed at a position corresponding to the snap lock 16 on the lower arc-shaped plate 15. By setting the snap 17 and the snap lock 16, the fixing and disassembly of the cable are made more convenient.

[0025] A U-shaped spring piece 12 is installed on the inner wall of the frame 11 close to the connecting plate 9. One end of the U-shaped spring piece 12 is installed on two of the arc-shaped plates 15. The U-shaped spring piece 12 has a certain elasticity, which can not only fix the arc-shaped plates 15 but also does not affect opening the arc-shaped plates 15 to put in or disassemble the cable.

[0026] Multiple screw holes are formed on the connecting plate 9, and screws 10 are installed on the multiple screw holes. The cooperation of the screw holes and the screws 10 facilitates fixing the device on the wall.

[0027] Two support plates 18 are installed at the inner bottom of the frame 11. One ends of the two support plates 18 are respectively installed on two of the arc-shaped plates 15 close to the inner bottom of the frame 11. By setting the support plates 18, the two lower arc-shaped plates 15 are supported to prevent the protection mechanism from tilting due to the weight of the cable.

[0028] When in use, the connecting plate 9 is fixed on the wall through the screws 10, thereby fixing the protection device on the wall. Then, the snap lock 16 is opened to separate the arc-shaped plates 15 where the snap 17 and the snap lock 16 are installed. The cable is placed into the placement area formed by connecting the four arc-shaped plates 15. After placement, the snap lock 16 is buckled onto the snap 17. Since the protection springs 14 are installed between the arc-shaped plates 15, when the cable expands and contracts due to heat in hot weather, the protection springs 14 between the arc-shaped plates 15 will expand outwards, so that the surface of the cable will not be unevenly stressed and the cable will not be torn, thus protecting the cable.
