Description
Technical field
The present invention relates to overvoltage protection product technical field more particularly to a kind of self-recovering type gas-discharge tubes.
Background technique
Gas discharge gap prevents the overvoltage such as lightning stroke, electromagnetic pulse, electrostatic in electronic equipment, signal, power-supply system
To having a wide range of applications in damage caused by electronic equipment.Gas-discharge tube is maintained to put since the system of power supply is capable of providing
The voltage and current of electricity, causes gas-discharge tube after overvoltage reliably cannot voluntarily close, that is, is referred to as " afterflow ".
In the protection circuit that gas-discharge tube participates in, after pulse current discharging, gas-discharge tube is in Low ESR shape
State, the power supply that gas-discharge tube is protected at this time may have electric current to flow through, and afterflow frequently can lead to power supply for a long time
System cannot work properly or even damage, and will lead to power supply short circuit, power-supply system cisco unity malfunction or due to discharge tube itself
Continuous discharge fever damage.
Summary of the invention
The technical problem to be solved by the present invention is to according to above-mentioned the deficiencies in the prior art, provide a kind of self-recovering type gas to put
Fulgurite solves the problems, such as the afterflow of gas-discharge tube.
Technical scheme is as follows:
A kind of self-recovering type gas-discharge tube, includes gas discharge tube body and bimetal leaf, and bimetal leaf is connected with contact,
Contact is contacted with the electrode of gas-discharge tube, realizes the connection of gas-discharge tube and protection circuit, when temperature increases, bimetal leaf
Band movable contact flicks gas-discharge tube, realizes the connection for disconnecting gas-discharge tube and protection circuit.
Further, the gas discharge tube body is placed in fixing seat, and fixing seat bottom both ends, which are provided with, connects pin,
It is fixed in fixing seat after the bottom part bending of the bimetal leaf, the pin that connects of fixing seat bottom end is put with the gas
The electrode of fulgurite connects, and the pin that connects of the fixing seat bottom other end is connect with the bimetal leaf.
Further, the sheet metal is fixed with the fixing seat by fixing glue.
Further, it is additionally provided with fixed link in the fixing seat, for fixing the gas discharge tube body.
Further, gas-discharge tube tube body setting is fluted, is provided with metal buckle on groove, on metal buckle
It is connected with metal card contact pin, metal card contact pin is connect after twice bended with the bimetal leaf.
Further, the metal card contact pin is fixed with the bimetal leaf by fixing glue.
Compared with prior art, it is simple and convenient that the invention has the following beneficial effects: structures, preferably solves gas discharge
The afterflow problem of pipe.

Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with attached drawing
Step ground detailed description.
As depicted in figs. 1 and 2, embodiment provided by the invention, a kind of self-recovering type gas-discharge tube include that gas is put
Fulgurite ontology 1 and bimetal leaf 2, bimetal leaf 2 are connected with contact 3, and contact 3 is contacted with the electrode 8 of gas-discharge tube, realize gas
The connection of body discharge tube and protection circuit, when temperature increases, bimetal leaf 2 flicks gas-discharge tube with movable contact 3, realizes and disconnects
The connection of gas-discharge tube and protection circuit.
Gas discharge tube body 1 is placed in fixing seat, and fixing seat bottom both ends, which are provided with, connects pin 4, bimetal leaf 2
It is fixed in fixing seat after bottom part bending by fixing glue 5, fixing seat bottom end connects pin 4 and gas-discharge tube
Electrode 8 connects, and the pin 4 that connects of the fixing seat bottom other end is connect with bimetal leaf 2.It is provided with fixed link 10 in fixing seat, uses
In fixed gas electric discharge tube body 1.
When there is " afterflow " since gas-discharge tube itself generates heat, gas discharge tubular heat passes through contact 3 and air conduction
Bimetal leaf 2 is conducted heat to, bimetal leaf 2 acts after the desired temperature has been reached, by touching of the contact on gas-discharge tube
Point 3 flicks, to disconnect the connection of discharge tube and protection circuit.It is double when temperature is down to the temperature spot that sheet metal 2 restores in pairs
Sheet metal 2 restores automatically, and contact 3 is pressed on gas-discharge tube again, and gas-discharge tube restores and the connection of protection circuit again.
As in Figure 3-5, another embodiment provided by the invention, a kind of self-recovering type gas-discharge tube.The present embodiment with
The distinctive points of a upper embodiment are: gas-discharge tube tube body setting fluted 9, are provided with metal buckle 7, metal on groove 9
It is connected with metal card contact pin 6 on buckle 7, metal card contact pin 6 is connect after twice bended with bimetal leaf 2, metal card contact pin 6
It is fixed by fixing glue 5 with bimetal leaf 2.Metal card contact pin 6 forms " U " font after bending twice.
The above disclosure is only the preferred embodiments of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, therefore equivalent changes made in accordance with the claims of the present invention, is still within the scope of the present invention.
