Abstract
The utility model discloses a novel capacitor which comprises a capacitor and a resistor. The resistor is connected between two ends of the capacitor so as to be parallel with the capacitor. The capacitor and the resistor are packaged into an integral body, and a plurality of pins are led out. The novel capacitor has a simple and compact structure, is easy to install, and is low in cost and good in reliability.
Description
Technical field:
The utility model relates to a kind of novel capacitor.
Background technology:
The general Support Capacitor that is used for the high-power system; require it to possess good sudden-wave absorbing ability; protection rear class electronic devices and components are operated in the metastable environment; simultaneously for avoiding some high value components and parts of rear class the phenomenon that overvoltage damages to occur; requirement is to the circuit overvoltage protection; for addressing this problem; usually adopt the piezo-resistance of correct position increase proper parameter in system, but external installation resistance need to increase mounting structure, also will consider simultaneously heat radiation and the lead-in inductance of piezo-resistance; this complex structure; take up room large, difficult design is installed trouble; cost is high, poor reliability.
Summary of the invention:
The purpose of this utility model provides a kind of novel capacitor, and this is simple in structure, compact, installs simple and easyly, and cost is low, good reliability.
The utility model is achieved by following technical proposals:
A kind of novel capacitor comprises electric capacity and resistance, and resistance is connected in parallel on the electric capacity two ends, and electric capacity and resistance plastic packaging one are also drawn some pins.
Resistance described above is piezo-resistance.
The integrally formed rectangle box body of electric capacity described above and resistance plastic packaging.
Some pins described above are 6, comprise the first pin, the second pin, the 3rd pin, the 4th pin, and the 5th pin and the 6th pin, are distributed on box side wall by per 2 one group.
Some mounting ears are protruded at the two ends of box body described above.
The utility model structure compared with prior art has following effect: 1) the utility model saves the external mounting structure of piezo-resistance by with electric capacity and resistance plastic packaging one and draw some pins, simple in structure, compact, to install simple and easyly, cost is low, reduce lead-in inductance, good reliability; 2) resistance is piezo-resistance, and piezo-resistance makes the macro-energy spike sudden-wave absorbing ability of capacitor stronger, makes simultaneously capacitor have the ability of overvoltage protection, prevents from puncturing; 3) the integrally formed rectangle box body of electric capacity and resistance plastic packaging, some pins are 6, comprise the first pin, the second pin, the 3rd pin, the 4th pin, the 5th pin and the 6th pin, are distributed on box side wall by per 2 one group, reasonable in design, compactness are connected simple and easy with outer member; 4) some mounting ears are protruded at the two ends of box body, make things convenient for capacitor to install, and are connected firmly.
Description of drawings:
Fig. 1 is the circuit diagram of capacitor of the present utility model;
Fig. 2 is capacitor stereogram of the present utility model.
Embodiment:
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Embodiment one: as depicted in figs. 1 and 2, the utility model is a kind of novel capacitor, comprises electric capacity 1 and resistance 2, and resistance 2 is connected in parallel on electric capacity 1 two ends, and electric capacity 1 and resistance 2 plastic packaging one are also drawn some pins 3.
Embodiment two: the basis at embodiment one increases following technical characterictic: described resistance 2 is piezo-resistances.
Embodiment three: the basis at embodiment one or embodiment two increases following technical characterictic: the integrally formed rectangle box body 4 of electric capacity 1 and resistance 2 plastic packagings.
Embodiment four: the basis at embodiment three increases following technical characterictic: some pins 3 are 6, comprise the first pin 31, the second pin 32, the 3rd pin 33, the 4th pin 34, the 5th pin 35 and the 6th pin 36, are distributed on box body 4 sidewalls by per 2 one group.
Embodiment five: the basis at embodiment three increases following technical characterictic: some mounting ears 41 are protruded at the two ends of box body 4.
Because the application is mechanical field, the apparent association of ability those of ordinary skill obtains: the technical characterictic independent assortment of the increase that embodiment two, embodiment three, embodiment four and embodiment five mention is combined into new technical scheme with the technical scheme of embodiment one.
Operation principle of the present utility model: according to the operating voltage of capacitor use; the electric current environment; piezo-resistance in electric capacity internal parallel appropriate size; use piezo-resistance when voltage is lower than its threshold values; the electric current that flows through it is minimum; be equivalent to a valve that shuts; when voltage surpasses a certain value UN; the electric current that flows through it increases sharply; the characteristic that is equivalent to valve open; can suppress the frequent abnormal overvoltage that occurs in the circuit, protective circuit is avoided superpotential infringement, makes simultaneously capacitor (instantaneous overvoltage or overcurrent) when running into surge; inside begins to reduce by the piezo-resistance impedance; its inner classes is like the mechanism opening of valve, and surge current passes through, and circuit in parallel or equipment surge current reduce with it; surge current in circuit is larger; the impedance of piezo-resistance is less, and is larger by the electric current of piezo-resistance, and piezo-resistance has individual residual voltage value; the limiting voltage of capacitor in parallel and external circuit and equipment has played the function of capacitor for voltage protection and equipment in residual voltage with it.
