Description
Technical field
The present invention relates to a kind of electronic devices and components, relate in particular to a kind of electrochemical capacitance varistor, belong to varistor manufacturing technology field.
Background technology
Piezo-resistance, owing to having excellent nonlinear characteristic and energy absorption capability, is therefore applied widely on electric power, electronic circuit.Along with high and new technology development, that equipment is is short, little, light, thin, functionalization, digitlization, intellectuality, low consumed development trend, and the antistatic of equipment, anti-interference protection will seem more and more important.Ultralow pressure piezo-resistance, as ultralow pressure Anti-surging power protection device, is widely used in the fields such as mobile phone, USB interface, computer, LCD, automotive electronics, integrated circuit (IC) chip.The SMD piezo-resistance of ultralow pressure relies on Japan, Germany, Korea S's import substantially at present, and because its internal structure is mainly thick film lamination, volume is little, but defect of the current ubiquity of this device, and through-current capacity is little.In circuit, run into large electric current by time, easily there is punch-through.Therefore,, in direct current ultralow pressure circuit, can also improve its security performance.
Summary of the invention
The object of the invention is for the SMD piezo-resistance through-current capacity of ultralow pressure little; when running into large electric current passing through in circuit; easily there is the deficiency of punch-through; a kind of electrochemical capacitance varistor is provided; there is the quick dual-use function of super large capacitor and voltage; be mainly used in direct current ultralow pressure equipment and can effectively get rid of noise jamming, pre-antistatic, the normal work of protection load equipment.
For achieving the above object, technical scheme provided by the invention is: a kind of electrochemical capacitance varistor, comprise shell, the left electrode that shell is sealed fixing base and drawn through base jack by fluid sealant, right electrode, the piezo-resistance that is being coated and fixed in the enclosure thin film chip, described piezo-resistance thin film chip is that internal layer scribbles silver electrode formation internal layer silver end face, skin scribbles the piezo-resistance film that silver electrode forms outer silver-colored end face, and be attached to tightly on outer silver-colored end face with the onesize insulating paper of piezo-resistance film, the cylindrical tube being wound into, described left electrode, right electrode respectively with internal layer silver end face, outer silver-colored end face tightly contacts, and pass through respectively left base jack and right base jack, draw outside base.
Take the present invention of above-mentioned measure, main installation bridges on direct current ultralow pressure device power supply (DPS) line both positive and negative polarity, and wherein an electrode connects direct-flow positive pole, and another electrode connects negative pole, and element does not have polarity, and two electrodes connect arbitrarily regardless of both positive and negative polarity.Direct voltage generation surge on power line, when circuit voltage rises suddenly, the resistance value of electrochemical capacitance varistor can decline suddenly, and unnecessary voltage pass through the piezo-resistance negative pole of flowing through by energy and releases away, makes DC power supply maintenance pressure constant state.When circuit voltage declines suddenly, electrochemical capacitance varistor, owing to self having larger electric capacity, supplements the voltage of circuit, makes DC power supply keep pressure constant state.While having noise jamming and electrostatic interference in circuit, because the electrochemical capacitance varistor of bridge joint has larger electric capacity, can effectively absorb clutter and static, the equipment DC power supply of making remains pressure constant state.
The present invention has the following advantages:
1. the present invention has super large capacitor and the quick dual-use function of voltage; through-current capacity is large; in ultralow pressure DC equipment, can effectively get rid of noise jamming and electrostatic interference, the equipment DC power supply of making remains pressure constant state, thereby effectively protects the normal work of load equipment.
Life-span of the present invention long, product safety performance is high.
3. the present invention is simple in structure, easy to process, and production efficiency is high, is applicable to mass industrialized production.
