Embodiment Construction

[0022] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other; the present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0023] As shown in Figure 1, the present invention provides a water-blocking digital communication cable. The cable includes a spacer 3, a pair of twisted wires 2, a filling layer 1, an inner sheath layer 4, a water-blocking layer 5, and an outer sheath from the inside to the outside. Layer 6; wherein, there are multiple pairs of twisted wires 2; the spacer 3 is arranged between the pair of twisted wires 2; the spacer 3 is used to separate the pair of twisted wires 2; specifically, the use of the spacer 3 replaces the metal armor It ensures the strength of the communication cable while reducing the weight of the communication cable, which is more convenient for installation and mai...

Abstract

The invention provides a water-blocking digital communication cable. The water-blocking digital communication cable comprises a separating frame, a plurality of twist pairs, a filling layer, an innersheath layer, a water-blocking layer and an outer sheath layer in sequence from inside to outside. The separating frame is arranged between the twist pairs, and is used for separating the twist pairs.Gaps of the twist pairs are filled with the filling layer, and the twist pairs are coated with the filling layer. The filling layer is used for filling the gaps formed when the twist pairs winding the cable. By adopting the technical scheme, the waterproofness of the digital communication cable is improved, the mechanical strength is good, and the cushioning performance is excellent; and meanwhile, good processability, easy molding forming, high thermal adaptability, high dimensional accuracy, uniform structure and convenient installation are achieved.

Description

technical field [0001] The invention belongs to the technical field of communication cables, and in particular relates to a water-blocking digital communication cable. Background technique [0002] Today, with the continuous improvement of communication information, the use of digital communication cables is increasing, and the use environment is also constantly being challenged; communication cables are also gradually equipped with anti-corrosion, flame resistance, compression resistance, tensile strength, anti-electromagnetic interference and water resistance. Performance, while the performance is improved, the manufacturing cost continues to increase, and the labor cost of installation and maintenance is also increased. [0003] In humid, underwater or corrosive environments, the water resistance and corrosion resistance of communication cables are the most important; the current communication cables, in order to reduce the weight of communication cables while adding othe...
