Description

Technical Field

[0001] This utility model relates to the field of radio frequency cable technology, and in particular to a polypropylene insulated radio frequency cable. Background Technology

[0002] Radio frequency (RF) cables are signal transmission cables and an indispensable component of modern electronic systems. They are widely used in wireless communication, broadcasting, radar, test and measurement instruments, medical equipment, satellite communication, and other fields.

[0003] Existing radio frequency cables mainly consist of a conductor, an insulation layer, an outer conductor, and a sheath. The insulation layer is often made of polyethylene, which results in poor temperature resistance and heavy weight. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a polypropylene insulated radio frequency cable.

[0005] This utility model provides a polypropylene insulated radio frequency cable, including an insulated core, and a braided layer and an outer sheath are sequentially arranged on the outside of the insulated core. The insulated wire core is composed of a conductor and a polypropylene insulation layer extruded outside the conductor.

[0006] Furthermore, the conductor is composed of several strands of tough copper wire twisted together.

[0007] Furthermore, the braided layer is a tough copper wire braided layer, which is braided on the outside of the insulated wire core.

[0008] Furthermore, the outer sheath is a polyvinyl chloride (PVC) outer sheath, which is extruded onto the outside of the braided copper wire layer.

[0009] Compared with the prior art, the beneficial effects of this utility model are: The cable of this utility model includes an insulated core, a braided layer, and an outer sheath. The insulated core consists of a conductor and a polypropylene insulation layer extruded on the outside of the conductor. Compared with the traditional polyethylene insulation layer, polypropylene has a lower density. With the same outer diameter of the insulation layer, the cable using the polypropylene insulation layer is lighter and more suitable for applications where lightweight cables are required. In addition, the temperature resistance of polypropylene is better than that of polyethylene, resulting in better temperature resistance of the cable.

[0010] It should be understood that the description in this utility model description section is not intended to limit the key or essential features of the embodiments of this utility model, nor is it intended to restrict the scope of this utility model. Other features of this utility model will become readily apparent from the following description. Attached Figure Description

[0014] Please refer to Figures 1-2 An embodiment of this utility model provides a polypropylene insulated radio frequency cable, including an insulated core 1, with a braided layer 2 and an outer sheath 3 arranged sequentially on the outside of the insulated core 1; The insulated core 1 is composed of a conductor 11 and a polypropylene insulation layer 12 extruded outside the conductor 11.

[0015] In this embodiment, the insulation layer in the insulated wire core 1 of this application is a polypropylene insulation layer 12, and the density of polypropylene is 0.89 g / cm³. 3 -0.92g / cm 3 The density of polyethylene is 0.94 g / cm³. 3 -0.97g / cm 3 Compared to traditional polyethylene insulation, polypropylene has a lower density. With the same outer diameter of the insulation layer, cables with polypropylene insulation are lighter and more suitable for applications requiring lightweight cables. In addition, polypropylene has a better temperature resistance rating than polyethylene, resulting in better temperature resistance performance of the cable.

[0016] Preferably, conductor 11 is composed of several strands of tough copper wire twisted together.

[0017] Preferably, the braided layer 2 is a tough copper wire braided layer, which is braided on the outside of the insulated core 12.
