[0020] Embodiment 1: Figure 1 As shown, a puncture flat sheathed cable for prefabricated buildings according to an embodiment of the utility model includes a cable core 200 and an outer sheath 300, the outer sheath 300 is wrapped around the cable core 200, the cable core 200 includes 2-core insulated wire cores 100 (2 equal cores) of the same specification, the 2-core insulated wire cores 100 are in contact with each other and arranged in parallel to form a flat structure, and the 2-core insulated wire cores 100 are specifically a phase line and a neutral line.

[0021] Furthermore, if Figure 1 As shown, the outer coating 300 in this embodiment is extruded on the outer periphery of the cable core 200 by the sheath plastic embedded extrusion, so that the outer coating 300 and the cable core 200 are tightly combined and become one, ensuring that the structure of the insulated core 100 is stable and the position is accurate, ensuring that when the external junction box pierces the branch electrode and contacts the single wire on the surface of the conductor, it will slide into the gap between the single wires of the conductor and enter the interior of the conductor 110.

[0022] Furthermore, if Figure 1 As shown, the insulated wire core 100 in this embodiment includes a conductor 110 and an insulating layer 120 from the inside to the outside. The conductor 110 is formed by twisting multiple core soft round copper wires in a non-tightly compressed circular manner. Generally, the conductor 110 is formed by twisting 7 cores of soft round copper wires of the same nominal diameter in a non-tightly compressed circular manner. The single wires are arranged as 1+6, including 1 core located in the center and 6 cores located on the periphery. When an external junction box punctures a branch electrode and contacts a single wire on the surface of the conductor, it will slide into the gap between the single wires of the conductor and enter the interior of the conductor. Such a conductor structure makes the tension of the conductor copper single wire to the puncture branch electrode uniform.

[0023] Furthermore, if Figure 1As shown, the insulating layer 120 in this embodiment is extruded on the conductor 110 by an insulating plastic embedded type, so that the conductor 110 has a stable structure and will not be locally deformed when the puncture branch electrode is inserted, so that the copper single wire and the puncture branch electrode are in contact more fully and reliably.

[0024] Furthermore, if Figure 1 As shown, the twisted pitch diameter ratio of the conductor 110 in this embodiment is 14-24, and the twisted pitch diameter ratio is the ratio of the twisted pitch diameter to the twisted outer diameter of the conductor 110. This twisted pitch diameter ratio range makes the copper single wire contact with the puncture branch electrode more fully and reliably and has good conductive performance.

[0025] Embodiment 2: Figure 2 As shown, the difference between this embodiment and the first embodiment lies in the number of insulating cores 100 in the cable core 200. The cable core 200 in this embodiment includes 3 insulating cores 100 (3 equal cores) of the same specification, specifically a phase line, a grounding protection line and a neutral line, wherein the grounding protection line is in the middle position.

[0026] Embodiment 3: Figure 3 As shown, the difference between this embodiment and the first embodiment lies in the number of insulating cores 100 in the cable core 200. The cable core 200 in this embodiment includes 5 insulating cores 100 (5 equal cores) of the same specification, specifically, phase A, neutral, phase B, grounding protection, and phase C.

[0027] Embodiment 4: Figure 4 As shown, the difference between this embodiment and the first embodiment lies in the number and specifications of the insulating cores 100 in the cable core 200. The cable core 200 of this embodiment is composed of two specifications of insulating cores 100, including 2 large-sized insulating cores 100 and 1 small-sized insulating core 100 (2+1 cores). The large-sized insulating cores 100 are specifically phase lines and neutral lines, and the small-sized insulating cores 100 are specifically grounding protection lines. The two specifications of insulating cores 100 are arranged at intervals, and the two ends are relatively large-sized insulating cores 100.

[0028] Embodiment 5: Figure 5 As shown, the difference between this embodiment and the first embodiment lies in the number and specifications of the insulating cores 100 in the cable core 200. The cable core 200 of this embodiment is composed of two specifications of insulating cores 100, including 3 large-sized insulating cores 100 and 2 small-sized insulating cores 100 (3+2 cores). The large-sized insulating cores 100 are specifically A-phase line, B-phase line, and C-phase line, and the small-sized insulating cores 100 are specifically neutral lines and grounding protection lines. The two specifications of insulating cores 100 are arranged at intervals, and the two ends are relatively large-sized insulating cores 100.

[0029] It should be noted that the specification of the insulated wire core in Embodiments 1 to 5 refers to the nominal cross-sectional area of ​​the conductor, which is specifically 0.5 to 35 mm2.
