Background technique

With the development of new energy vehicles and the development and popularization of electric vehicle technology, the research on cables for electric vehicles has also become a crucial part.

The purpose of the utility model is to provide a reinforced cable, as shown in Figure 1, comprising at least one wire, the wire comprising a conductor 1 and an insulating layer 2 sleeved on the outside of the conductor 1, each of the conductors 1 is formed by twisting a plurality of conductive monofilament bundles, and at least one first bulletproof wire 3 is arranged in the insulating layer 2 along the extension direction of the cable.

With the development of new energy vehicles, the development and popularization of electric vehicle technology, the research of cables for electric vehicles has also become a crucial part. The existing small square multi-core cables are generally formed by twisting multiple core wires into cables and extruding a sheath 5. However, due to the small cross-sectional area of the small square, the breaking force of the wire is also relatively small, causing the cable to be easily broken in a complex use environment, resulting in safety or economic losses. Therefore, a new structure of cable is urgently needed to solve the above problems.

Each conductor 1 in the cable is formed by twisting a plurality of conductive monofilament bundles, and at least one first bulletproof wire 3 is arranged in the insulating layer 2. The addition of the bulletproof wire can enhance the mechanical strength and breaking force of the cable, ensure that the cable is not easily broken in a complex use environment, extend the service life of the cable, and improve the safety of electricity use.

Furthermore, as shown in FIG. 2 , at least one second bulletproof wire 4 is interspersed in the plurality of strands of the conductive monofilaments, and each of the conductors 1 is formed by twisting a plurality of strands of the conductive monofilaments and the second bulletproof wire 4 .

The conductor 1 in which the conductive monofilaments and the second bulletproof wires 4 are twisted together increases the mechanical strength of the entire cable.

Furthermore, as shown in FIG. 3 , a sheath 5 is disposed on the outer shell of the conductor, and at least one third bulletproof wire 6 is disposed inside the sheath 5 along the extending direction of the cable.

Adding the first bulletproof wire 3 in the insulating layer 2 and the third bulletproof wire 6 in the sheath 5 can increase the mechanical strength of the cable.

Furthermore, as shown in FIG. 4 , a sheath 5 is provided outside the insulating layer 2 , and at least one fourth bulletproof wire 7 is provided inside the sheath 5 along the extending direction of the cable.

Adding a second bulletproof wire 4 to the conductive monofilament of the conductor 1, adding a first bulletproof wire 3 to the insulating layer 2 and adding a third bulletproof wire 6 to the sheath 5, and adding bulletproof wires sequentially from the inside to the outside of the cable can greatly increase the mechanical strength of the cable.

Furthermore, as shown in FIG. 5 , there are multiple wires, which are arranged in sequence, with a gap between two adjacent wires, and the multiple wires are collectively covered with a same sheath 5 , and at least one fifth bulletproof wire 8 is provided in the gap.

Adding a first bulletproof wire 3 in the insulating layer 2 and providing a fifth bulletproof wire 8 in the gap between two adjacent conductors can multiply increase the mechanical strength of the cable.

Furthermore, as shown in FIG6 , there are multiple wires, and the multiple wires are collectively covered with the same sheath 5 , and the multiple wires are distributed on a circle with the center of the cross section of the sheath 5 as the center, and at least one sixth bulletproof wire 9 is provided at the center of the multiple wires.

A plurality of sixth bulletproof wires 9 are arranged at the center to cooperate with the first bulletproof wires 3 in the insulating layer 2 to enhance the breaking force of the cable and improve the overall mechanical strength of the cable, thereby ensuring its normal use in a complex use environment and increasing its practical life.

Furthermore, the sixth bulletproof wire 9 is provided with multiple strands which are twisted together.

A plurality of sixth bulletproof wires 9 are arranged at the center and twisted together, so as to increase the mechanical strength of the center of the cable.

Furthermore, as shown in FIG. 7 , a filler is disposed between the outer walls of the plurality of conductive wires and the inner wall of the sheath 5 , and a plurality of seventh bulletproof wires 10 are disposed in the filler.

The first bulletproof wire 3 arranged in the insulating layer 2, the multiple seventh bulletproof wires 10 arranged in the filler and the multiple sixth bulletproof wires 9 arranged at the center position work together to improve the overall mechanical strength of the cable.

Furthermore, the conductive monofilament is a copper wire with a diameter of 0.03 mm.

Furthermore, the lay length of the conductive monofilament is 50mm-60mm.

It should be noted that in other embodiments, bulletproof wire can be added to the conductor 1 or the sheath 5, or bulletproof wire can be added to both the conductor 1 and the sheath 5. It can be set according to actual needs and is not limited here. For example, in the fifth, sixth and seventh embodiments, bulletproof wire can be added to the conductor 1 or the sheath 5, or bulletproof wire can be added to both the conductor 1 and the sheath 5 to further achieve the effect of enhancing the mechanical strength of the cable.
