Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a tensile-resistant fully armored cable. Background Technology

[0002] Cables are conductors that transmit electrical energy. They are classified as bare wires, magnet wires, and insulated wires. Bare wires have no insulation layer and include copper and aluminum flat wires, overhead stranded wires, and various profiles (such as shaped wires, busbars, copper busbars, aluminum busbars, etc.). They are mainly used for outdoor overhead cables and indoor busbars and switch boxes.

[0003] Current cables have poor tensile strength and are prone to breakage. In severe weather conditions, the physical protection of cables is poor when they are hit by external objects. Therefore, it is necessary to propose a cable with better tensile strength and physical protection. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a tensile-resistant fully armored cable with better tensile strength and physical protection.

[0005] To solve the above-mentioned technical problems, the present invention includes a cable core, and an armor strip is spirally wound around the outside of the cable core in such a way that adjacent loops overlap each other by a portion. A groove in the extension direction is opened on one side of the armor strip, and a retaining strip is fixedly installed in the extension direction on the other side of the armor strip, and the retaining strip engages with the groove.

[0006] Preferably, a groove in the extension direction is opened on the side of the armor strip facing the cable core near one edge, and a retaining strip is fixedly installed on the other side of the armor strip away from the cable core near the other edge in the extension direction.

[0007] To improve the sealing effect of the armor, several first sealing strips are fixedly installed along the length direction on the bottom surface of the groove, and several second sealing strips are fixedly installed along the length direction on the other side of the armor strip away from the cable core and near the other edge.

[0008] In a preferred configuration, the second sealing strip and the first sealing strip are engaged with each other in a staggered manner.

[0009] To enhance the overlapping effect of adjacent armor bands, bends are added between the two edges of the armor bands.

[0010] To improve the strength and rust resistance of the armor, the armor belts are preferably made of stainless steel.

[0011] To reduce manufacturing difficulty and cost, both the first and second sealing strips are made of rubber and are fixed to the armor strip by adhesive bonding.

[0012] To improve the sealing effect, the first and second sealing strips are set at equal intervals and fit together when they are in contact with each other.

[0013] In summary, this utility model spirally winds the armor tape onto the cable core surface by overlapping adjacent loops, which facilitates processing. The combination of the locking strip and the groove prevents the armor tape from easily detaching under tension. The interlocking sealing strips also act as a buffer during the tensile process of the armor. The sealing strips prevent external substances from entering the cable core surface and causing corrosion, thus improving the overall tensile, bending, and impact resistance of the cable. Furthermore, the sealing provides comprehensive protection for the cable core, greatly extending the cable's service life. This design is suitable for outdoor cable wiring.

[0019] See attached document Figure 1-4 This type of tensile-resistant fully armored cable includes a cable core 1, with an armor strip 2 spirally wound around the outside of the cable core. A groove 3 is formed along the length direction on one side of the armor strip 2 facing the cable core, and several first sealing strips 4 are fixedly arranged along the length direction on the bottom surface of the groove 3. Several second sealing strips 5 and retaining strips 6 are fixedly arranged along the length direction on the other side of the armor strip away from the cable core, near the other side edge. Figure 1 As shown, the armor strips of adjacent loops are spirally wound on the surface of the cable core in such a way that a portion of them overlap. The second sealing strip 5 and the retaining strip 6 are inserted into the groove 3 inside the armor strip of the adjacent loop. At this time, the retaining strip is located on one side of the groove. The second sealing strip and the first sealing strip cooperate with each other in a staggered manner, that is, at least one first sealing strip is located between two second sealing strips. Similarly, at least one second sealing strip is located between two first sealing strips.

[0020] A bend 7 is set between the two edges of the armor strip. By setting the bend, the armor strip of adjacent loops can be better overlapped when it is wrapped around the cable core. It can also increase the bending strength of the armor strip. After the armor strip is wrapped around the cable core to form armor, the overall strength is higher.

[0021] The armor strips are preferably made of stainless steel strips, and the bends and grooves are made by stamping. This design can improve the strength and rust resistance of the armor.

[0022] Both the first and second sealing strips are made of rubber and are fixed to the armor strip by adhesive bonding. This design facilitates the fixing of the sealing strips and reduces manufacturing difficulty and cost.

[0023] The first and second sealing strips are set at equal intervals and are in a close fit when they are in contact with each other. This design can ensure improved sealing effect. When the cable is bent, the first and second sealing strips, which are in contact with each other, can maintain the sealing effect through their own deformation capacity.

[0024] The armor tape is spirally wound onto the cable core surface by overlapping adjacent loops. This facilitates processing, and the combination of the locking strips and grooves prevents the armor tape from easily coming undone under tension. The interlocking sealing strips also act as a buffer during the tensile process of the armor. The sealing strips prevent external substances from entering the cable core surface and causing corrosion, thus improving the overall tensile, bending, and impact resistance of the cable. They also provide a sealing function, protecting the cable core in all directions and greatly extending the cable's service life. This method is suitable for outdoor cable wiring.

[0025] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
