Abstract
The utility model discloses a kind of low residual voltage gas discharge tube, comprise top electrode, earthenware and bottom electrode, described top electrode and bottom electrode are encapsulated in earthenware two ends, and the inwall of described earthenware is provided with T-shaped conductive strips, and described T-shaped conductive strips are made up of carbon dust; Be provided with groove in the middle part of the outer face of top electrode and bottom electrode, and the inner face being positioned at earthenware is outwardly; Inert gas is filled with in the package cavity that the encapsulation of described top electrode, earthenware and bottom electrode is formed.T-shaped conductive strips of the present utility model can provide more discharge tip, and the gas inside gas discharge tube can more easily be ionized, and therefore when surge or thunder-strike current occur, greatly can reduce residual voltage, also just can play a protective role sooner.
Description
Technical field
this practicality relates to a kind of security type components and parts, is specifically related to a kind of low residual voltage gas discharge tube.
Background technology
At present; at communication safety-security area; gas discharge tube is due to low electric capacity; there is large Surge handling capability, in all kinds of base station, router; the communication equipments such as Set Top Box are used in a large number; but gas discharge tube shortcoming is exactly that reaction speed is excessively slow, and residual voltage is higher, therefore certain hidden danger is existed to the equipment of its protection.
Summary of the invention
For the problem that existing gas discharge tube residual voltage is higher, the utility model provides a kind of low residual voltage gas discharge tube.
The technical scheme that the utility model is taked is: a kind of low residual voltage gas discharge tube, and comprise top electrode, earthenware and bottom electrode, described top electrode and bottom electrode are encapsulated in earthenware two ends, and the inwall of described earthenware is provided with T-shaped conductive strips.
Further, described T-shaped conductive strips are made up of carbon dust.
Further, described T-shaped conductive strips by lead for retractable pencil on earthenware inwall draw and formed.
Further, in the middle part of the outer face of described top electrode and bottom electrode, be provided with groove, and the inner face being positioned at earthenware is outwardly.
Further, be filled with inert gas in the package cavity that the encapsulation of described top electrode, earthenware and bottom electrode is formed, described inert gas comprises argon gas, neon.
The beneficial effects of the utility model are: top electrode and earthenware and bottom electrode pass through High-temperature Packaging, in package cavity, fill the inert gas of certain pressure intensity, and introduce earthenware inwall the T-shape conductive strips (use lead for retractable pencil (2H) draw) drawn, when gas discharge tube is subject to surge voltage or thunderbolt, due to T-shape conductive strips be use lead for retractable pencil (2H) draw, discharge tip more more than common " 1 " type conductive strips can be produced, make gas discharge tube discharge faster, greatly reduce residual voltage simultaneously.
Accompanying drawing explanation
Fig. 1 is that structure of the present utility model splits schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of low residual voltage gas discharge tube, comprises top electrode 1, earthenware 2 and bottom electrode 3, and described top electrode 1 and bottom electrode 3 are encapsulated in earthenware 2 two ends, and the inwall of described earthenware 2 is provided with T-shaped conductive strips 4.
In the utility model, top electrode 1, earthenware 2 and bottom electrode 3 are encapsulated by high temperature (830 degree 30 seconds).In package cavity, fill the inert gas (Ar, Ne etc.) of certain pressure intensity.T-shaped conductive strips 4 on earthenware 2 inwall use lead for retractable pencil (2H) draw formation.When gas discharge tube is subject to surge voltage or thunderbolt, because T-shaped conductive strips 4 use lead for retractable pencil (2H) institute to draw, be made up of carbon dust, therefore can produces more discharge tip, make gas discharge tube discharge sooner, greatly reduce residual voltage.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art and is realized.
