Embodiment Construction

[0027] like Figure 1 to Figure 4 As shown, the low-loss coaxial cable includes an inner conductor, and the outside of the inner conductor is covered with an insulating layer 2, an outer conductor layer 3, a dielectric layer, a shielding layer 6, an inner sheath 8, a water-absorbing layer 9 and an outer sheath in turn. Set of 10.

[0028] The outer surface of the outer sheath 10 is provided with several axial grooves 101 extending in the axial direction, and the axial grooves 101 are connected with a circumferential groove 102 around the outer sheath 10. When encountering rainy weather, the axial grooves 101 and The circumferential groove 102 has a drainage effect, and the rainwater will flow to the ground along the axial groove 101 and the circumferential groove 102 . The axial grooves 101 are evenly distributed in the circumferential direction of the outer sheath 10, the cross-sectional shape of the axial grooves 101 is semicircular, and the cross-sectional shape of the joi...

Abstract

The invention provides a low-loss coaxial cable, and belongs to the technical field of cables. The low-loss coaxial cable comprises an internal conductor, wherein an insulation layer, an external conductor layer, a dielectric layer, a shielding layer, an internal sheath, a water absorption layer and an outer sheath sequentially wrap the internal conductor, water absorption particles are filled inthe water absorption layer, a plurality of axial grooves are formed in an outer surface of the outer sheath and extend along an axial direction, and the axial grooves are connected with a circumferential groove encircling the outer sheath by a circle. The low-loss coaxial cable has the advantages of favorable waterproof performance, high strength, low dielectric and low loss.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a low-loss coaxial cable. Background technique [0002] Coaxial cables are used in mobile, microwave communication, electronic countermeasures, instrumentation, antennas, base stations, navigation, industrial robots, and transmission of high-frequency signals in equipment. Conventional cables are often bent or twisted during use, so high requirements are placed on the cable's resistance to breakage during the bending and twisting process, and excellent fatigue resistance is required due to long-term use. [0003] During the laying and operation of coaxial cables, when mechanical stress or external force causes damage to the cable sheath or damage to the joints, in rainy weather, moisture or moisture will infiltrate along the longitudinal and radial gaps of the cables, causing the cable insulation to age due to moisture. At the same time, the immersion of water will ca...
