DETAILED DESCRIPTION
[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0014] See attached Figure 1-3A pressure-resistant cable for new energy vehicles, comprising an outer skin 1, a tape layer 2 and an insulating layer 7, and a plurality of conductors 6 arranged in the insulating layer 7, a pressure-resistant assembly 5 is arranged outside the conductor 6, the pressure-resistant assembly 5 comprises a pressure-resistant seat 51 and four pressure-resistant pads 52 embedded around the pressure-resistant seat 51, the conductor 6 is installed in the pressure-resistant pad 52, the pressure-resistant seat 51 and the four pressure-resistant pads 52 form a cylindrical shape, the pressure-resistant seat 51 and the pressure-resistant pads 52 are both made of rubber material, a support column 54 is installed in the middle of the pressure-resistant seat 51, a slot 56 penetrating the pressure-resistant seat 51 is arranged around the support column 54, and a support arm adapted to the slot 56 is installed on the pressure-resistant pad 52 57, the support arm 57 is inserted into the slot 56, and a plurality of anti-compression rods 58 are distributed in the anti-compression pad 52. Arc plates 55 are installed on the edges of the four sides of the anti-compression seat 51. This arrangement helps to protect the wire core from being damaged by external collision and extrusion. On the basis of ensuring the overall compressive strength, it can prevent the adjacent wires 6 from being squeezed. Although the anti-compression component 5 is made of rubber material as a whole, the overall structure will not be easily deformed because of the addition of the arc plate 55 and the anti-compression rod 58. The anti-compression pad 52 and the anti-compression seat 51 are connected by plug-in type, which prevents the wire 6 from being deflected due to high-intensity external force.
[0015] The support column 54, the arc plate 55 and the support arm 57 are all made of plastic material, so that while ensuring the structural strength, it can also prevent the rubber material of the anti-pressure seat 51 and the anti-pressure pad 52 from being damaged when subjected to external pressure;
[0016] It should be noted that, in this embodiment, a compression-resistant layer 4 is provided outside the insulating layer 7, and a braided layer 3 is provided outside the compression-resistant layer 4. The braided layer 3 is made of epoxy resin fiber material. The braided layer 3 is glued between the tape layer 2 and the compression-resistant layer 4. The epoxy resin fiber material has very high strength and can withstand greater pressure and load, thereby improving the overall compression resistance of the cable.
[0017] The pressure-resistant layer 4 is formed by weaving a mesh of copper-clad aluminum wires and wrapping a rubber material on the outside. The specific production steps are: first, weave the copper-clad aluminum wires into a mesh, then put it into a mold to pour liquefied rubber, and finally cool it to shape. The copper-clad aluminum wires can resist external signal interference, and the aluminum wires themselves have a certain plasticity. Finally, the external rubber can also achieve pressure resistance.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.
