Abstract
The utility model provides a novel gas discharge tube for coaxial cable belongs to and prevents the lightning stroke overvoltage technical field field, including cylindrical cavity, the cavity comprises the end cap at cavity wall and upper and lower both ends, is provided with inert gas in the cavity, wherein, radially is provided with the electrode in the cavity, and the both ends of electrode are passed the end cap at upper and lower both ends respectively and are connected with the sinle silk of the coaxial cable at both ends, the cavity wall is by inlayer, skin and be located inside filler and constitute, be provided with the bump on the electrode. The beneficial effects of the utility model are that: using this gas discharge tube, can concatenating in the coaxial transmission line cable, can reach higher transmission frequency bandwidth, the loss is lower, and thunder and lightning discharge capacity is big, and protection voltage is more excellent, safe and reliable's characteristics.
Description
Technical field
This utility model is related to cable anti-lightning strike overvoltage technical field, more particularly, to a kind of new for coaxial cable
Gas-discharge tube.
Background technology
Thunder and lightning is very big to the harm of the mankind, and the overvoltage surge being sensed by lightening pulse is to the destructiveness of communication equipment very
Greatly, coaxial cable lightning protection device is requisite protection device in microwave communication, is connected to transmitting antenna or reception antenna and machine
On coaxial cable between room equipment, invade machine room for eliminating lightning surge pulse, thus avoiding the infringement to communication equipment.
On the one hand coaxial cable lightning protection device must can filter lightning current, can not have other impacts to the signal of communication of transmission simultaneously.
The core component of coaxial cable lightning protection device is exactly gas-discharge tube at present.
Traditional coaxial cable lightning protection device mainly adopts the gas-discharge tube of two end electrodes formula, and one end is connected to coaxial transmission
On holding wire heart yearn, the other end is connected with the shell body of coaxial cable lightning protection device, the ground connection that the earthing of casing discharges as lightning current
Line.Traditional mode can cause to be lost in transmitting procedure, causes to waste.
Utility model content
The purpose of this utility model is to provide a kind of novel gas discharge tube for coaxial cable.
For achieving the above object, this utility model is realized by following measure: a kind of for coaxial cable
Novel gas discharge tube, including circular cylindrical cavity, cavity is made up of the plug of cavity wall and upper/lower terminal, is provided with cavity
Noble gases, wherein, are radially provided with electrode in described cavity, the two ends of described electrode are each passed through described upper/lower terminal
Plug is connected with the core of the coaxial cable at two ends；Described cavity wall is made up of internal layer, outer layer and internally positioned filler；Described
Salient point is provided with electrode.
Wherein, the plug of described upper/lower terminal is obtained for insulating ceramic materials.
Wherein, described cavity wall is that conductor material iron-nickel alloy is obtained.
Wherein, described filler is carbon black fibre.
This utility model from adopt different electrode structure modes in the market.Gas-discharge tube traditional at present adopts
Upper and lower ends electrode, middle confining gases cavity mode, and this utility model then adopts intermetallic metal needle electrode to pass through one
Cylindrical metallic tube wall and the mode that upper/lower terminal is the closed gas cavity that ceramic plug is formed.Same using this utility model
Axis cable lightning protection device can be serially connected in coaxial transmission cable, can reach higher transmission frequency bandwidth, and loss is lower, and thunder and lightning is through-flow
Capacity is big, more excellent, the safe and reliable feature of protection voltage.
The beneficial effects of the utility model are: using this gas-discharge tube, can be serially connected in coaxial transmission cable, can reach
Higher transmission frequency bandwidth, loss is lower, and thunder and lightning discharge capacity is big, more excellent, the safe and reliable feature of protection voltage；And lead to
Cross the structure and material to electrode and cavity wall further to improve, preferably reduce loss.
