USB (Universal Serial Bus) molded wire structure and molded wire cabling pair-twisted setting device

Abstract

The invention discloses a USB (Universal Serial Bus) molded wire structure and a molded wire cabling pair-twisted setting device; a molded wire comprises IP (Internet Protocol) signaling wires, 2C power wires, a weaving shielding layer, an insulating layer, a coat and a ground wire, wherein the two pair-twisted IP(Internet Protocol) signaling wires are arranged at the centers of a USB (Universal Serial Bus) molded wire; the 2C power wires are symmetrically arranged at both sides of the two pair-twisted IP(Internet Protocol) signaling wires and are sequentially covered by the weaving shielding layer and the insulating layer; the ground wire is arranged inside the weaving shielding layer; and wire body insulating layers are arranged on the IP (Internet Protocol) signaling wires and the 2C power wires. According to the molded wire cabling pair-twisted setting device, an eye model fixing mount is arranged at a distance between the two IP signaling wires and the two 2C power wires, which enter a wire passing plate of a cabling machine from a payoff stand; the eye model fixing mount is slightly larger than the passing wire diameter after core wires of the IP (Internet Protocol) signaling wires are pair-twisted; and a cabling eye model which is used for pair-twisting is arranged on the eye model fixing mount. The USB (Universal Serial Bus) molded wire is beneficial to the stability of signaling wire transmission and the symmetry arrangement of the molded wire and enables wire rods and wire bodies to be effectively protected.

Description

technical field [0001] The invention belongs to the technical field of cable cabling, and relates to a cable structure and cabling technology, in particular to a USB type wire structure and a type wire cabled pair twist assembly device. Background technique [0002] Existing digital devices mostly use USB cables to transmit data and signals, and the basic structure of USB cables is four lines, such as figure 1 As shown, one pair of twisted pairs is a differential signal line marked D+ / D-, called 1P, used for signal transmission, each using half-duplex differential signals and working together, and the other two lines are responsible for power transmission, marked It is VCC / GND, called 2C. In the traditional production process, this kind of USB cable is a 1P signal line that is twisted separately first, and then combined with a 2C power line and added with a shielding layer, and finally cabled. [0003] In the existing traditional cabling process, two pairs of twisted white...

Problems solved by technology

Therefore, the 1P signal line in the USB type line is also entangled with the 2C power line during the handling process and when it is connected and combined with other components, so it is easy to cause damage to the structure of the wire itself (such as: wire diameter, twist length) Damaged, resulting in unstable transmission of the signal line performance of the USB cable during use
