[0033] Embodiment 1

[0034] See also Figure 1 As shown, this embodiment is a high temperature and high pressure resistant sheathed wire with nano-carbon nickel silicone shielding for new energy vehicles, comprising:

[0035] A conductor 11, an insulation 12 wrapped around the conductor 11, a nano-carbon nickel silica gel 13 wrapped around the outer layer of the insulation 12, and a sheath 14 wrapped around the nano-carbon nickel silica gel 13;

[0036] A limiting component, located outside the sheath 14;

[0037] The conductor 11 is made of soft round copper wire or tinned soft round copper wire with a purity of more than 99.99%;

[0038] Using soft round copper wire or tinned soft round copper wire with a purity of more than 99.99% helps to improve the transmission efficiency of the wire, extend its service life, and ensure the reliability of the wire under various environmental conditions.

[0039] The single wires of the conductor 11 are twisted in layers, and the conductor 11 has a regular twisting structure of 1+6+12+18, and the twisting direction is left;

[0040] The twisted structure can effectively reduce electromagnetic interference inside and outside the wire, allowing the sheathed wire to adapt to complex installation environments and wiring requirements.

[0041] The insulation 12 and the sheath 14 are both made of a new type of high temperature resistant silicone rubber material;

[0042] The high temperature resistant silicone rubber material used has the advantages of high temperature resistance, heat stability, corrosion resistance, insulation performance, softness and elasticity.

[0043] Working principle:

[0044] The conductor 11 is a bare soft round copper wire, and the conductor 11 is in a regular 1+6+12+18 twisted structure. An insulating layer is uniformly extruded outside the conductor 11. The insulation 12 is made of high-temperature resistant silicone rubber material and is produced by thin-wall extrusion. The shielding layer is a new composite material composed of silicone rubber as a base material and nano-carbon nickel conductive particles embedded therein, namely nano-carbon nickel silica gel 13, which is directly extruded as an intermediate layer on the outside of the wire core insulation as a shielding layer, replacing the original braided aluminum foil shielding method. The sheath 14 is made of high-temperature resistant silicone material and is extruded through a thin wall as a protective layer to protect the entire wire.

[0045] This step reduces the molding process from two shielding steps to one step, which greatly improves production efficiency.

[0046] Embodiment 2

[0047] See also Figure 1-Figure 3 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0048] The limiting assembly includes a semi-ring frame 21 sleeved on the outside of the sheath 14. The semi-ring frame 21 is provided with two groups, an upper limiting frame 22 fixed on the left and right surfaces of the bottom end of the upper semi-ring frame 21 and a lower limiting frame 23 fixed on the left and right surfaces of the top end of the lower semi-ring frame 21;

[0049] The semi-ring frame 21 is used to be installed on the outer surface of the sheath 14, and to limit the sheath 14 when the sheath 14 is torn off. The upper limit frame 22 and the lower limit frame 23 are used to connect the semi-ring frame 21 together;

[0050] A spring 24 is fixed inside the lower limit frame 23, a limit column 25 is fixed on the top of the spring 24, the limit column 25 is located inside the upper limit frame 22, and limit blocks 26 are fixed on the outer surfaces of the front and rear sides of the limit column 25. The upper limit frame 22 is provided with limit slots 27 on the front and rear sides, and the limit blocks 26 are located inside the limit slots 27;

[0051] The limit groove 27 is provided for the limit block 26 to move inside the limit groove. Under the elastic force of the spring 24, a force in the opposite direction can be applied to the semi-ring frame 21, so that the semi-ring frame 21 can move on the surface of the sheath 14. The limit column 25 is used to receive and install the limit block 26.

[0052] The limiting block 26 and the upper limit frame 22 are provided with a limiting hole 28, and a limiting rod 29 is movably connected inside the limiting hole 28. A connecting buckle 291 is fixed on the outer surface of the limiting rod 29, and an elastic rope 292 is fixed inside the connecting buckle 291. The other side of the elastic rope 292 is fixed inside the upper limit frame 22.

[0053] By inserting the limiting rod 29 into the limiting hole 28, the limiting block 26 can be fixed at the top of the limiting groove 27, the connecting buckle 291 is convenient for applying an outward pulling force to the limiting rod 29, and the elastic rope 292 is convenient for taking and using the limiting rod 29 again;

[0054] Working principle:

[0055] When moving the half ring frame 21 position;

[0056] Apply an outward pulling force to the connecting buckle 291 so that the limiting rod 29 is separated from the limiting hole 28, and then apply a reverse force to the semi-ring frame 21 manually, so that the limiting block 26 moves downward in the limiting groove 27 so that the semi-ring frame 21 is separated from the contact with the sheath 14, and then the semi-ring frame 21 is moved to the desired position, and the force applied to the semi-ring frame 21 is canceled. Under the elastic force of the spring 24, the limiting block 26 moves to the top of the limiting groove 27, and then the limiting rod 29 is inserted into the limiting hole 28.

[0057] This step not only makes the torn length of the sheath 14 more accurate, but also avoids cracks in the sheath 14, which would reduce the shielding interference resistance of the sheath cable.

[0058] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
