Detailed Description

In order to make the objects, features and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1, a digital communication cable according to an exemplary embodiment of the present disclosure includes a plurality of sets of pairs 1, each set of pairs 1 includes a twisted pair formed by twisting two single wires 11, the plurality of sets of pairs 1 are arranged in a straight line in parallel with each other, and two adjacent sets of pairs 1 are connected to each other by a suspension wire 2. Taking the example that the number of the pairs 1 is four, the four pairs 1 are connected with each other by three suspension wires 2, the four pairs 1 are in a straight shape, each two adjacent pairs 1 are in a 8 shape, and the twisted pairs in each pair 1 are in an 8 shape.

In the present embodiment, the requirement of digital signal transmission can be satisfied by using a twisted pair formed by twisting two single wires 11. Because a plurality of groups of line pairs 1 are arranged in parallel in a straight line, the wiring is more convenient, wiring grooves are not required to be arranged, and the structure of various application scenes can be attached; secondly, the structure is simple, the working procedure is simple during production, the manufacture of the crystal head is convenient, and the production efficiency can be greatly improved; moreover, the digital communication cable only needs to be packaged in a roll without adopting a packaging box, the roll packaging occupies small space, and the cost can be reduced and the digital communication cable is convenient to carry. Two adjacent pairs 1 are connected through the suspension wire 2, the distance between the pairs 1 is increased, the pairs 1 are arranged in a separated mode, crosstalk interference between the pairs 1 is reduced, and the problem that the spiral bending of the wire cannot be straightened due to the fact that the pairs 1 are mutually wound is solved. The suspension wire 2 may be made of any of a variety of materials, including but not limited to polyvinyl chloride, polyethylene, glass fiber reinforced plastic, low smoke and halogen-free materials, polyurethane, and thermoplastic polyurethane.

Referring to fig. 1 to 3, in an embodiment, each pair 1 includes an outer sheath 12, the outer sheaths 12 of two adjacent pairs 1 are in line contact with each other to form a line contact portion 120, and the line contact portion 120 is covered in the suspension wire 2 (see fig. 1). It is understood that there may be gaps between the outer sheaths 12 of two adjacent pairs 1, and the gaps are filled with the suspension wires 2 to connect the outer sheaths 12 of two adjacent pairs 1 (see fig. 2). Specifically, in the cross section of the pair 1, the outer sheath 12 may be a circular ring circumscribing the twisted pair, or a ring wrapping the twisted pair (as shown in fig. 3).

In the embodiment, the outer jacket 12 is arranged on the periphery of each pair of twisted pairs, so that each group of pairs 1 is separated by the outer jacket 12, compared with the prior art that the shielding layers 13 between the adjacent pairs 1 are directly contacted, the distance between the pairs 1 is further increased, the crosstalk interference between the pairs 1 is reduced, and the problem that the wires cannot be straightened due to spiral bending caused by mutual winding of the pairs 1 is solved. Moreover, the space between the two adjacent pairs 1 is increased by filling the suspension wires 2 when the gaps exist between the outer sheaths 12 of the two adjacent pairs 1, compared with the way that the suspension wires 2 cover the wire contact part 120 when the outer sheaths 12 of the two adjacent pairs 1 are in wire contact, but the material consumption is increased and the occupied space is enlarged, so that the wire contact mode between the outer sheaths 12 is preferably selected, the crosstalk interference between the pairs 1 is reduced, and meanwhile, raw materials can be saved. In addition, the outer sheath 12 may be made of any of a variety of materials, including but not limited to polyvinyl chloride, polyethylene, glass fiber reinforced plastic, low smoke zero halogen, polyurethane, and thermoplastic polyurethane, to protect the internal structure of the digital communication cable.

Referring to fig. 4, in the above-mentioned embodiment, the suspension wire 2 is bonded to the outer sheath 12, that is, the suspension wire 2 is bonded and connected between the outer sheaths 12 of two adjacent pairs 1 by an adhesive. Preferably, the suspension wire 2 and the outer sheath 12 are integrally formed, the suspension wire 2 and the outer sheath 12 are made of the same material, and a grinding tool with the same shape as the outer sheath 12 and the suspension wire 2 is extruded and formed on a sheath machine in the production process, so that the operation steps are reduced, the production efficiency is greatly improved, and the structure is stable.

In one embodiment, the twisted pairs of the plurality of pairs 1 satisfy the parallel condition in the cross section of the digital communication cable. Or, the twisted pairs of the multiple sets of pairs 1 are not all parallel to each other, as shown in fig. 5, taking the number of the sets of pairs 1 as four sets as an example, the pairs 1 are sequentially the first set to the fourth set from left to right, wherein the twisted pairs of the second set and the fourth set of pairs 1 are parallel to each other, the twisted pair of the first set of pairs 1 is inclined at a certain angle with respect to the twisted pair of the second set of pairs 1, and the twisted pair of the third set of pairs 1 is perpendicular to the twisted pair of the second set of pairs 1.

In the present embodiment, the above two twisted pairs can be placed in a manner that can solve the problem that the twisted wire cannot be straightened due to the mutual winding of the pair 1, and can ensure the structure of the cable to be attached to various application scenarios, but a manner that the twisted pair of the pair 1 satisfies the parallel condition is preferable, which can stabilize the performance and structure of the digital communication cable.

In one embodiment, the geometric centers of the plurality of pairs 1 in the cross section of the digital communication cable are in the same straight line, and the distances between the geometric centers of two adjacent pairs 1 are equal.

In this embodiment, the geometric center of each pair is the twisted point 112 of the twisted pair, and no matter how the twisted pair is placed, the twisted pair is placed by rotating around the geometric center, and the position of the geometric center is not changed and is always on the same straight line, so that the internal structure of the digital communication cable is uniformly distributed, the overall structure is stable, and the best effect can be achieved when the digital signal is transmitted.

In one embodiment, pair 1 further includes a shield 13 that surrounds the outer circumference of the twisted pair. The shielding layer 13 is arranged, so that external electromagnetic interference can be well resisted, electromagnetic wave radiation of the shielding layer can be controlled, normal work of other surrounding equipment and networks can not be interfered, and crosstalk interference is reduced to the minimum.

In one embodiment, the single wire 11 includes a copper wire 110 and an insulating layer 111 disposed on the copper wire 110.

In one embodiment, the number of pairs 1 is four. In the embodiment, the line sequence of the four groups of line pairs 1 from left to right is white (orange) orange, white (green) green, white (blue) blue and white (brown) brown according to the 368B standard, and the production of the crystal head is convenient in the production process. However, the number of the pairs 1 is not limited to four, and may be set to satisfy the standard defined in YD/T1019-2013 polyolefin insulation level twisted pair cable for digital communication.
