Abstract
A novel gas discharge tube relates to a discharge tube which is applied to electronic equipment, signal systems and power systems to prevent the electronic equipment, the signal systems and the power systems from being damaged by overvoltage and operation of overvoltage due to lightning and electromagnetic waves. The novel gas discharge tube comprises a first terminal electrode, a second terminal electrode and a porcelain tube. The first terminal electrode is disposed at one end of the porcelain tube, the second terminal electrode is boss-shaped and is arranged at the other end of the porcelain tube, and a boss of the second electrode extends into the porcelain tube. The first terminal electrode, the second terminal electrode and the porcelain tube form a sealed cavity, the sealed cavity consists of a gap between the boss of the second terminal electrode and the porcelain tube, inert gas is filled in the sealed cavity, and a metal piece is arranged on the inner wall of the porcelain tube. The novel gas discharge tube has the advantages that a function of increasing current passing capacity and a function of reducing the volume of a gas discharge tube are unified, and the novel gas discharge tube is wide in application.
Description
Technical field
The utility model relate to be applied to prevent in electronic equipment, signal system and the power-supply system to be struck by lightning, overvoltage that electromagnetic pulse is brought and switching overvoltage be to they hurtful discharge tubes, refers to that especially a kind of through-current capability reaches the little gas discharge tube of volume greatly.
Background technology
Have a wide range of applications in the infringement that overvoltage that gas discharge tube prevents to be struck by lightning in electronic equipment, signal system and power-supply system, electromagnetic pulse is brought and switching overvoltage cause them.We can say that the size of volume size and through-current capability is to weigh the important indicator of gas discharge tube performance and advanced technology degree.Along with the development of technology and the needs of device miniaturization, in general, require gas discharge tube should volume little, through-current capability is big again.Up to the present, only performance is outstanding in one aspect for gas discharge tube, and perhaps volume is little, but through-current capability is also little; Perhaps through-current capability is big, but its volume is also big.Thereby performance is not comprehensive, can't satisfy client's, but also through-current capability big demand little to gas discharge tube not only volume.
The gas discharge tube of existing two electrodes as shown in Figure 1.In this structure, two termination electrodes 1 are arranged on the two ends of metallized ceramic tubes 2 and form airtight cavity 3, put at two termination electrodes 1 on the interior surface opposing of metallized ceramic tubes 2 and coat cathode emission material 5, termination electrode 1 welds with weld tabs 4 with the joint portion of metallized ceramic tubes 2, fills with inert gas in airtight cavity 3.The discharging gap of this structure is confined to two termination electrodes 1 and puts between the interior surface opposing of metallized ceramic tubes 2, the surface that can form discharge path also is confined to the interior surface opposing that two termination electrodes 1 put in metallized ceramic tubes 2, thereby the surface area that can form discharge path is little, and conveyance capacity is just little.In general, the surface area that can form discharge path in the discharging gap is big more, conveyance capacity is just big, therefore, increasing the surface area that can form discharge path in the discharging gap, is one of main way that improves the gas discharge tube conveyance capacity, but, when can form the surface area of discharge path in increasing discharging gap, the volume of gas discharge tube is as far as possible little, the key point of contradiction that Here it is.
Summary of the invention
The gas discharge tube that the utility model is intended to overcome prior art is outstanding or the little or through-flow big deficiency of volume of performance in one aspect only, releases a kind of new gas discharge tube.Not only through-current capability is big for it, and volume is little.
To achieve these goals, finish above-mentioned task, a kind of new gas discharge tube of the utility model adopts following technical scheme:
A kind of new gas discharge tube of structure the utility model comprises first termination electrode, second termination electrode and porcelain tube; First termination electrode is arranged on an end of porcelain tube, and second termination electrode becomes the boss shape, and second termination electrode is arranged on the other end of porcelain tube, and the boss of second termination electrode puts in the porcelain tube; First termination electrode, second termination electrode and porcelain tube are configured to a closed cavity, and described closed cavity comprises the gap that has between the boss of second termination electrode and porcelain tube, fill with inert gas at closed cavity; Be shaped on metallic object on the inwall of porcelain tube.
Technique scheme is further set forth:
The described metallic object that is shaped on the inwall of porcelain tube is sheet metal or metal level.
Described porcelain tube is a metallized ceramic tubes.
Coat cathode emission material on the surface of first termination electrode of facing closed cavity and the surface of second termination electrode.
Described porcelain tube welds with scolder with the junction of first termination electrode, second termination electrode respectively.
Working mechanism of the present utility model is: the boss of second termination electrode puts in the porcelain tube, and is shaped on sheet metal or is shaped on metal level on the inwall of porcelain tube, makes the inwall of porcelain tube have the function as discharge path that is equivalent to electrode.Like this, the surface area that can become discharge path in the closed cavity of the present utility model comprises: 1) first termination electrode and the second termination electrode facing surfaces are long-pending; 2) side of the boss of second termination electrode and porcelain tube inwall facing surfaces are long-pending.As seen, the long-pending surface area that can become discharge path of the side of the boss of second termination electrode and porcelain tube inwall facing surfaces is that peculiar structure of the present utility model causes.Increase greatly owing to can become the surface area of discharge path in the utility model closed cavity, so the also increase greatly of through-current capability during its discharge.
A kind of new gas discharge tube of the present utility model is compared with prior art, and beneficial effect is:
One, through-current capability improves.Increase greatly owing in closed cavity, can become the surface area of discharge path, thereby can when discharge, form big through-current capability.The second, volume is little.It is that boss by second termination electrode puts in the porcelain tube that the surface area that can become discharge path in the utility model closed cavity increases greatly, and the inwall that makes porcelain tube is shaped on sheet metal or is shaped on that metal level realizes, just closed cavity is fully utilized, do not increase the volume of gas discharge tube.Under the prerequisite of the volume that does not increase gas discharge tube, realized improving its through-current capability, in other words, and under the situation that keeps equal through-current capability, the volume of the gas discharge tube that can diminish.Really realize both having increased through-current capability, reduced the unification of gas discharge pipe volume again.Its three, purposes is wide, uses in the infringement that overvoltage of can prevent to be struck by lightning in electronic equipment, signal system and power-supply system, electromagnetic pulse being brought and switching overvoltage cause them.
