Embodiment Construction

[0037] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0038] Please refer to figure 2 and image 3 , where an example of a section of existing coaxial cable 20 is shown. Coaxial cable 20 generally includes a center conductor 22, a dielectric layer 24 ring around the center conductor 22, a foil / braid shield 26 ring around the dielectric layer 24, and a sheath 28, the center conductor 22 Various conductive materials can be used, such as copper, steel, or copper-clad steel. The dielectric layer 24 can be formed using various dielectric materials such as solid polyethylene (PE), foamed polyethylene (FP), fluorinated ethylene propylene (FEP), foamed fluorinated ethylene propylene (FFEP), air medium / polyethylene (AD / PE) and so on.

[0039] From image 3 It can be clearly seen that the shielding layer 26 may include an inner foil layer 26a and an outer braidin...

Abstract

The invention discloses a method and a device for isolating auxiliary signals by using coaxial cable routing. An antenna grounding system comprises a coaxial cable including an inner conductor, a dielectric layer wrapping the inner conductor, a shielding layer covering the dielectric layer and an outer sheath; and a grounding block including a groove for accommodating the coaxial cable; wherein the grounding blocked is opened to accommodate the coaxial cable in the groove, and also includes at least one cutting assembly with a predetermined size in the groove; and the at least one cutting assembly penetrates the outer sheath to keep contact with the shielding layer, but not reaching the dielectric layer, when the coaxial cable is accommodated in the groove and the grounding block is closed.

Description

technical field [0001] The present invention relates to grounding devices and methods for various cables (such as coaxial cables): in particular, it relates to grounding blocks for coaxial cables and methods of use thereof. Background technique [0002] The US National Electric Code ('National Electric Code, NEC) states that, for safety reasons, before a coaxial cable enters a house, the point of entry must be provided with a cable shield grounding point. The coaxial cable shield should be in contact with a ground wire. If the grounding wire is an aluminum wire, its wire gauge shall not be smaller than No. 8; if it is a solid copper wire, its wire gauge shall not be smaller than No. 10. Another purpose of grounding is to reduce equipment damage from lightning. [0003] Today's method of grounding is to use a device called a ground block. Figure 1A — Figure 1C A top view showing examples of three types of grounding blocks containing F-type connector terminals, namely sin...
