This embodiment also discloses a production method of a transmission line for VR equipment, which is used to produce a transmission line for VR equipment. The production method includes:

Tin-plated copper with a preset number and a preset diameter is selected and twisted to form a wire with a preset lay length. It can be understood that different wires in the transmission line for VR equipment have different functions according to their functions, so there are different numbers, different diameters, and different twist lengths. The field can set the above parameters according to actual needs, and the specific values are not given here. Specific limits.

Specifically, in order to produce the transmission line for VR equipment as in Example 1, it is necessary to twist the following four kinds of wires: Wire 1. Select 7 high-quality tinned coppers with a diameter of 0.083TC±0.001 and twist them to form a high-speed transmission The signal conductor adopts a 300-type copper twisting machine, and the set twist distance is 3.1±0.3mm. Conductor 2. Select 7 pieces of high-quality tinned copper with a diameter of 0.064±0.003 and twist them to form a high-speed transmission signal conductor. Use a 300-type copper twisting machine and set the twist distance to 2.5±0.3mm. Conductor 3. Select 7 pieces of high-quality tinned copper with a diameter of 0.1±0.003 and twist them to form a conductor. Use a 300-type (or 400#) copper twisting machine and set the twist distance to 4.5±0.5MM. Wire 4. Select 61 pieces of high-quality tinned copper with a diameter of 0.06±0.005 and twist them to form a wire. Use a 400-type (or 500#) copper twisting machine and set the twist distance to 6.8±0.5MM.

Further, the high-frequency wire core adopts the coaxial horizontal winding process, that is, the shielding wire 410 wound in the right direction, the double-layer isolation technology of wrapping the copper foil 420 in the left direction and the outer wrapping tape 430 in the right direction, wherein the shielding wire 410 selects 50 copper wires with a diameter of 0.04TC, copper foil 420 selects PET4/CUJ, W=3.0mm, and outer wrapping tape 430 selects hot-melt self-adhesive PET (polyester tape PET4/AC W=2.5mm). In addition, the right-left-right interlocking process is beneficial to ensure more reliable winding. The production process of double-layer isolation is molded in two times and heated and fixed, which not only reduces the distortion of the high-speed core wire 400 caused by high-frequency signals during isolation, but also solves the problem of wrapping when the core assembly is processed due to the use of hot-melt materials. The cladding component 500 is troubled by one end being loose and the other being tight, which improves product quality and ensures the stability of high-frequency transmission.

The accuracy is controlled by 100% online wire diameter monitoring equipment, automatic wire diameter control system, and the tolerance of transmission line 210 wire diameter is controlled within ±0.02mm.

Further, the twisted ground wire 220 is formed by twisting seven copper wires with a diameter of 0.064TC±0.005mm, and then twisted with two green and white transmission lines 210 pairs, using a 400-type high-frequency twisting machine; The distance is 14±2MM, and the direction is twisted rightward; the length of the green and white transmission lines 210 should be the same or the length of the white should be 1-2mm, so as to ensure the physical length consistency of the twisted wires. Finally, a layer of 13UM*5mm single-side silver aluminum foil is wrapped to form the transmission core wire 200 of the twisted wire structure.

Six wires with preset parameters are covered with insulating material, and three filler wires 140 are added to twist to form the functional core wire 100 .

Use FEP material with superior dielectric constant to synthesize the power line 110, the wire diameter is 0.78±0.03mm, and the color of the power line 110 is red (its accuracy passes 100 ％Online wire diameter monitoring equipment, automatic wire diameter control system, making the power cord 110 wire diameter tolerance control within ±0.03mm).

Further, yellow, red, and black second functional core wires 130, blue first functional core wires 120, and two red power cords 110, and three cotton wires (20s) are added as filling wires 140 to form a cable , using a 300-type high-frequency twisting machine; set the twisting distance to 20±3mm, and the direction is right twisting; (the first blue functional core wire 120 and the two red power cords 110 need to be 100% untwisted), The functional core wires 100 of the twisted wire structure are formed by cabling.

Twist eight high-speed core wires 400, transmission core wires 200 and functional core wires 100, and add a first cage stranded ground wire 310, two second cage stranded ground wires 320 and two third cage stranded ground wires 330 Combined into a core assembly.

That is, the 5M transmission cable for VR equipment can meet the high-frequency signal transmission requirements of USB 3.1 high-frequency requirements.

Because the frequency of use of VR equipment requires that the transmission line used for VR equipment can meet the high life requirements of 60,000 times of high swing and 10,000 times of torsion, the durability test includes swing test and torsion test. The selection of transmission lines for VR equipment must meet the following requirements: multi-strand copper wire 7/0.083 tinned copper and 61/0.06 tinned copper should be selected to enhance the bending life of the conductor, and the material of the core wire should be selected for physical properties such as tensile extension and aging Superior Teflon FEP material. The coaxial horizontal winding production stranding process adopts 100% untwisted stranding technology to release stress and ensure that the wire structure is not deformed. The integrated cable adopts a new planetary 18-head back-twist device to release stress and ensure that the wire structure does not deform.

Durability test data are as follows: swing test requirements: R = 25.4mm. Lifting weight: 2N; 20 times/min; ±54 degrees; 60,000 times; after the test, the transmission line for VR equipment has good conduction and no bad appearance. Torsion test (without lifting weight), frequency 20RPM, angle ±180 degrees: 10,000 times; after the test, the sample has good conduction and no bad appearance. That is, the durability test can meet the high service life of 60,000 swings and 10,000 torsion tests.

Furthermore, the length of the transmission line for VR equipment reaches 5M, and the wire is required to be soft so that the wire will not be knotted or bent during mobile use. Therefore, the production method of the transmission line for VR equipment also includes a softness test. Due to the above production method, the copper wire of the conductor is selected to be finer copper wire (0.083MM, 0.06MM, 0.04MM design), the core wire material is selected from soft FEP material, and the wrapping tape is made of soft and ultra-thin copper foil 420PET4/CUJ , W=3.0mm and ultra-thin hot-melt self-adhesive PET (polyester tape PET4/AC W=2.5mm) and the outer tube extruded PVC, and with the coaxial horizontal rolling untwisting / cable untwisting process to release twist The line stress wire is soft, so the standard softness of the transmission line for VR equipment after processing and production is ≤150TSU, which meets the normal use of users, and at the same time, there will be no knotting, bending deformation, etc.

The above content is only a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope. limits.
