Detailed Description

The invention will be further described with reference to examples of embodiments shown in the drawings.

The first embodiment is as follows: as shown in fig. 1, the ribbon cable includes a cable core and a mylar-coated layer 4 (jacket layer) coated outside the cable core.

The cable core includes a plurality of signal lines 1 and/or a plurality of power cord 2, and in this embodiment, the cable core includes many signal lines 1 and many power cord 2. The signal lines 1 and/or the power lines 2 each extend in a first direction, and the signal lines 1 and/or the power lines 2 are arranged in a second direction, wherein the first direction is perpendicular to the second direction. In fig. 1, the first direction is a vertical direction on the drawing, and the second direction is a horizontal direction on the drawing. Thus, the signal lines 1 and the power lines 2 are extended in parallel and arranged in a row so that the entire cable core assumes a flat ribbon shape.

The cable core also comprises a plurality of reinforcing wires 3, and the reinforcing wires are used for enhancing the tensile property and the bending resistance of the ribbon cable. The enhancement type also extends in the first direction and is aligned in the second direction in common with the signal line 1 and/or the power supply line 2. The reinforcing thread 3 can be cotton thread, nylon thread or bulletproof thread.

The arrangement sequence of the signal line 1, the power line 2 and the reinforcing line 3 is randomly arranged. For example, the signal line 1 and the power line 2 may be arranged at an interval; for another example, the signal lines 1 and the power lines 2 are respectively divided into a plurality of groups, each group includes a plurality of signal lines 1 or power lines 2, and the plurality of groups of signal lines 1 and the plurality of groups of power lines 2 are arranged at intervals. In this embodiment, the signal lines 1 are divided into two groups, one group includes four signal lines 1, the other group includes two signal lines 1, the power lines 2 are divided into one group, includes two power lines 2, and the two groups of signal lines 1 are respectively located on two sides of one group of power lines 2. The two enhancement lines 3 are divided into two groups and are disposed on two sides of the whole body formed by the signal line 1 and the power line 2, as shown in fig. 1, or may be disposed between the signal line 1 and the signal line 1, or between the power line 2 and the power line 2, or between the signal line 1 and the power line 2.

The diameter of the signal wire 1 and/or the diameter of the power wire 2 are equal to the diameter of the reinforcing wire 3 and are arranged in a fitting manner, so that a cable core with the same thickness is formed, the thickness direction of the cable core is the third direction perpendicular to the first direction and the second direction, namely the vertical direction on the drawing plane in fig. 1, and the width of the cable core in the second direction is larger than the thickness of the cable core in the third direction.

The coated mylar layer 4 is made of a PET mylar material by using an FFC (flexible flat cable) bonding process, namely, an upper PET film and a lower PET film of the cable core are bonded through glue layers on the inner surfaces of the upper PET film and the lower PET film to form the coated mylar layer 4.

In the above scheme, the signal line 1 and the power line 2 both adopt coaxial cables. The signal line 1 includes a signal line conductor core 11 for transmitting radio signals, a signal line insulating layer 12 covering the signal line conductor core 11, and a signal line interference preventing layer covering the signal line insulating layer 12. The signal line interference preventing layer for reducing interference of surrounding metal objects on signal transmission comprises a signal line copper alloy shielding layer 13 covering the signal line insulating layer 12, a signal line copper foil or aluminum foil mylar layer 14 covering the signal line copper alloy shielding layer 13, and a signal line hot melting mylar layer 15 made of PET material covering the signal line copper foil or aluminum foil mylar layer 14. Wherein the signal line copper alloy shielding layer 13 may be grounded. The power supply line 2 includes a power supply line conductor core 21 for transmitting a power supply signal, and a power supply line insulating layer 22 covering the power supply line conductor core 21.

Example two: as shown in fig. 2, the ribbon cable of the present embodiment is different from the first embodiment in that: the signal wire 1 and the power wire 2 both adopt twisted-pair cables. The signal line 1 includes two twisted-pair signal transmission lines 16, and the signal transmission line 16 includes a signal line conductor core 11, a fluorine-based signal line insulating layer 12 covering the signal line conductor core 11, and a signal line interference preventing layer covering the signal line insulating layer 12. The signal line interference preventing layer comprises a signal line copper alloy shielding layer 13 covering the signal line insulating layer 12, a signal line copper foil or aluminum foil mylar layer 14 covering the signal line copper alloy shielding layer 13, and a signal line hot melting mylar layer 15 made of PET material covering the signal line copper foil or aluminum foil mylar layer 14. The power supply line 2 includes two twisted power supply transmission lines 23, and the power supply transmission lines 23 include a power supply line conductor core 21 and a fluorine-based power supply line insulating layer 22 covering the power supply line conductor core 21.

The advantage of above-mentioned scheme lies in: 1. the multi-layer shielding structure has excellent electromagnetic interference resistance; 2. the sheath layer adopts an FFC (flexible flat cable) laminating process, is orderly arranged, has no distortion, occupies small space and is resistant to bending; 3. the polyfluorinated insulation layer is made of high-temperature-resistant polyfluorinated insulation materials and has multiple special functions of low smoke, zero halogen, environmental protection, high/low temperature resistance, aging resistance, oil resistance and the like; 4. the round structure of the traditional cable is changed into a belt-shaped structure, cabling and weaving are not needed, and the damage of each process to signal transmission is reduced.
