Embodiment Construction

[0016] The invention provides a shielded cable with a wound copper foil layer. The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings, so as to make it easier to understand and grasp.

[0017] Shielded cables with a copper foil layer such as figure 1 with figure 2 As shown, it includes a PTFE core wire 2 with several guide cores 1 inside. The outer periphery of the PTFE core wire 2 is seamlessly wound with a rolled copper foil tape 3, and the outer periphery of the rolled copper foil tape 3 is provided with a protective agent curing sleeve 4, and the protective agent is cured. The outer periphery of the cover 4 is provided with a PVC protective cover 5 .

[0018] The specific implementation process and principle description:

[0019] The molding of the PTFE core wire 2 is extrusion molding, that is, extrusion wrapping of PTFE material is performed on the guide core 1 to form the PTFE core wire 2. This...

Abstract

The invention discloses a shielding cable with a wound copper foil layer. The shielding cable comprises a PTFE core wire internally provided with a plurality of conducting cores, wherein a calenderingcopper foil belt is seamlessly wound on the periphery of the PTFE core wire, a protective agent curing sleeve is arranged on the periphery of the calendering copper foil belt, and a PVC protective sleeve is arranged on the periphery of the protective agent curing sleeve. According to the invention, the calendering copper foil tape replaces the traditional tin-copper-dipped metal braided sleeve, so that the cost of the shielding cable is effectively reduced while the shielding performance of the shielding cable is guaranteed; by adopting the design of the specific protective agent curing sleeve, the wound calendering copper foil strip can be cured, so that the stability requirement of the wound calendering copper foil strip in a cable is met, the characteristics of high-temperature resistance, corrosion resistance and the like are achieved, and the service life is prolonged; the calendering copper foil tape adopts a winding single-side bonding mode, so that the structural stability ofthe shielding layer is further improved, and a certain fatigue resistance is achieved; and copper foils abut against each other to form a shielding closed loop, so that the shielding performance is remarkable.

Description

technical field [0001] The invention relates to a shielded cable with a wound copper foil layer, belonging to the technical field of shielded cables. Background technique [0002] The arrival of 5G networks has had a major impact on key components, especially connectors and cables used in wireless and wired infrastructure. Recently, the United States and the United Kingdom have announced the accelerated development of 5G networks, which has injected vitality into the entire network industry. Now, Western economies are trying to compete with China's intensive rollout of 5G technology. [0003] Making this leap at scale, however, will depend on adopting new cable technologies. Around the world, copper-based mobile backhaul architectures are being upgraded to packet transport over fiber optics. Optical cables can transmit higher bandwidth, so they are an essential configuration for the processing speed of future 5G network products. Small cells, new devices and products to ...
