[0020] Depend on Figures 1 to 4 This utility model discloses a multi-layer armored tensile-resistant antistatic flexible connector, comprising a flexible connector body 1, with a grounding wire 2 penetrating one end of the flexible connector body 1 and a grounding wire 3 penetrating the other end. The flexible connector body 1 consists of a steel strip armored outer layer 4, a fluororubber outer layer 5, a spiral steel wire 1 6, a spiral steel wire 2 7, a fluororubber intermediate layer 8, a nylon mesh interlayer 9, a fluororubber inner layer 10, a carbon fiber mesh interlayer 11, and a copper wire braided inner layer 12. The structure consists of a steel belt armored outer layer 4 covering the outer surface of a fluororubber outer layer 5; spiral steel wire 1 6 and spiral steel wire 2 7 connected in a staggered manner to the inside of the fluororubber outer layer 5; a fluororubber intermediate layer 8 connected to the inner surface of the fluororubber outer layer 5; a nylon mesh interlayer 9 connected to the inside of the fluororubber intermediate layer 8; a fluororubber inner layer 10 connected to the inner surface of the fluororubber intermediate layer 8; a carbon fiber mesh interlayer 11 connected to the inside of the fluororubber inner layer 10; and a copper wire braided inner layer 12 connected to the inner surface of the fluororubber inner layer 10.

[0021] The outer steel strip armor layer 4 provides outer reinforcement, improving puncture resistance and tensile strength. The fluororubber outer layer 5, spiral steel wire one 6, spiral steel wire two 7, fluororubber intermediate layer 8, nylon mesh interlayer 9, fluororubber inner layer 10, and carbon fiber mesh interlayer 11 provide sealed protection and high tensile strength. The copper wire braided inner layer 12, grounding wire one 2, and grounding wire two 3 provide anti-static properties. The grounding effect is improved through the grounding design at both ends.

[0022] The outer layer 4 of the steel strip armor is a braided structure. The outer layer 5 of fluororubber, the first spiral steel wire 6, the second spiral steel wire 7, the middle layer of fluororubber 8, the nylon mesh interlayer 9, the inner layer of fluororubber 10, and the carbon fiber mesh interlayer 11 are an integral extrusion molding structure. The inner layer 12 of copper wire braid and the inner layer of fluororubber 10 are glued together. Copper rings 13 are fixedly installed at both ends inside the inner layer of fluororubber 10.

By setting up limiting rings, threaded connecting sleeves, O-ring one, O-ring two, and O-ring three, a double seal can be formed during connection. The outer and inner seals effectively improve the sealing performance of the connection, preventing flammable and explosive gases from entering the interior of the flexible connecting pipe.
