Technical field
The present invention relates to technical field of basic electronic devices more particularly to a kind of gas-discharge tubes.
Background technology
Gas-discharge tube belongs to a kind of switching mode protection device, uses usually as over-voltage protector, generally makes at present
Gas-discharge tube is to be encapsulated solder thawing by high temperature by insulation tube body and its two end electrodes, tube cavity filled with
Inert gas will cause product both ends when the applied voltage at gas discharge pipe electrode both ends is more than the breakdown voltage of gas
Gap discharge between electrode becomes low resistance state, tubular body gas discharge conducting, to protect circuit from high-impedance state rapidly
In other devices, in addition simultaneously, if the overvoltage duration long either frequency of occurrences it is higher or occur for a long time or
When high current, gas-discharge tube causes body self-heating cooking to heat up because bearing long-time or frequent overcurrent, and excessively high temperature is not
But the safe handling that other devices in circuit can be influenced, the risk for causing gas-discharge tube to there is short circuit or burst, or even burn
, there is fire in customer service circuit plate.
Invention content
Technical problem to be solved by the invention is to provide one kind can either providing effective protection for circuit, and can be in mistake
Disconnecting circuit when electric current, the gas-discharge tube for avoiding long-time power current or super-high-current from having an adverse effect circuit.
In order to solve the above technical problems, the technical solution used in the present invention is：A kind of gas-discharge tube, including gas are put
Fulgurite ontology, it is characterised in that：Further include pedestal and fuse, the gas discharge tube body and the fuse are fixed on institute
It states on pedestal, the gas discharge tube body is connected in series with the fuse, and the part of the fuse is close to the gas
The insulation tube body setting of body electric discharge tube body.
Further technical solution is：The gas discharge tube body includes insulation tube body, is welded electrode using solder
The both ends of the insulation tube body are connected to, are sealed insulation tube body by electrode, pin is connect with the electrode respectively, the gas
Electric discharge tube body is fixedly connected by the pin with the pedestal.
Further technical solution is：The fuse is wound in the periphery of the insulation tube body.
Further technical solution is：Upper half setting of the fuse portion close to the insulation tube body.
Further technical solution is：Lower half setting of the fuse portion close to the insulation tube body.
Further technical solution is：It is provided with shell on the outside of the gas discharge tube body and fuse, it is described
Shell is fixedly connected with the pedestal, and using there is fillable particulate matter to be filled between the pedestal and the shell.
Further technical solution is：One end of the fuse extends to outside the shell.
Further technical solution is：The pedestal is pcb board, one of those described pin passes through on pcb board
Copper foil line is connect with one end of the fuse.
It is using advantageous effect caused by above-mentioned technical proposal：The discharge tube includes the gas discharge being connected in series with
Tube body and fuse pass through certain long-time power current or excessive electricity when discharge tube and fuse are cascaded
When stream, conducting inside discharge tube, body self-heating cooking temperature increases fusing fuse or fuse directly fuses, thus by gas coming through
The failure of current of discharge tube, can either provide effective protection for circuit, but can in overcurrent disconnecting circuit, so that circuit is used
It is safer.
