Description
Technical field
The present invention relates to a kind of resistor, particularly relate to a kind of miniature fixed resistor.
Background technology
Resistor, mainly utilizes made by material that resistance coefficient is larger, produces inhibition by resistor to electric current, changes electron stream flux according to this; And resistor can be divided into fixed resistance (Fixedresistor) and the large class of variable resistor (Variableresistor) two according to its working method.
With fixed resistance, the clavate resistance 10 with pin as shown in Figure 1 and the sheet shape resistance 20 of not having a pin is as shown in Figure 2 divided into again according to its mounting means, there is the clavate resistance 10 of pin mainly based on porcelain rod, porcelain rod skin makes metal film by the spraying of airless spraying technology again, the resistive layer such as carbon film or metal oxide film, last again through cutting, welding lead-in wire and armor coated and formed, the described clavate resistance with pin directly carries out grafting installation by its pin, therefore its use install very convenient, although have the feature of power height, but namely its maximum shortcoming is that volume is larger, and miniaturized application demand cannot be applicable to.
And do not have sheet shape resistance 20 mainly printed resistor layer, a conductor on high heat conduction porcelain plate of pin; then cut required resistance, plating is manufactured protective layer and formed; the volume of described shape resistance 20 is minimum and can be applicable to accurate circuit application; but therefore its power be also less than clavate resistance, and described shape resistance itself does not have a pin and cannot do the installation of plug-in type.
From the above, though clavate resistance and flap-type electricity group respectively have its feature and applicable field domain, both have individually again the restriction in use, between the two also cannot mutually with complementary, necessity thus still to be improved.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of miniature fixed resistor, has that volume is little, power is high and can the feature of direct grafting, can improve that general rod resistor amasss large and generally sheet shape resistor power is low and cannot the shortcoming of grafting use.
For solving the problems of the technologies described above, miniature fixed resistor provided by the invention, comprises:
A slice shape resistance, has two lateral electrodes.
Two pins, make by conductive material, the first end conductive solder of a described pin in a described lateral electrode of described shape resistance, the first end conductive solder of pin described in another in described shape resistance another described in lateral electrode.
One resistive coating, is coated on the first end of pin described in described shape resistance and two.
Further improvement is, wears a pillar respectively between the two ends of pin described in two, and the second end of pin described in two passes corresponding described pillar, and described pillar isolation material is made.
Further improvement is, described resistive coating is glass glaze coating.
The present invention has that volume is little, power is high and can the advantage of direct grafting: the present invention can be applicable to the mounting means that pin grafting uses by overall structural allocation, and the general resistor of overall electrical resistance device and equal-wattage can have less volume again in comparison, and miniaturized application can be applicable to; Under the specification of same volume, then can provide higher rated power, improve the applicability used.

Embodiment
As shown in Figure 3, be the stereo appearance figure of the miniature fixed resistor of the embodiment of the present invention; As shown in Figure 4, be the partial sectional perspective view of the miniature fixed resistor of the embodiment of the present invention; The miniature fixed resistor of the embodiment of the present invention comprises:
A slice shape resistance 30, has two lateral electrodes 31.
Two pins 40, make by conductive material, and pin 40 described in two respectively with one end conductive solder in each lateral electrode 31 of described shape resistance 30, be specially the first end conductive solder of a described pin 40 in a described lateral electrode 31 of described shape resistance 30, the first end conductive solder of pin 40 described in another in described shape resistance 30 another described in lateral electrode 31.
One resistive coating 50, is coated on pin 40 described in described shape resistance 30 and two and is connected one end and the first end of described shape resistance 30; The described resistive coating 50 of the present embodiment is glass glaze coating.
Two pillars 60, between the two ends being set in pin 40 described in two respectively, and the other end of pin 40 described in two i.e. the second end passes pillar 60 described in two, and described pillar 60 is with made by isolation material.
Be more than structural configuration and the feature of the miniature fixed resistor of the embodiment of the present invention, be directly plugged in by pin described in two 40 mounting means that circuit board provides plug-in type during use, the convenience therefore used is high; Pillar 60 on pin 40 described in two then can be avoided each described pin 40 and other electronic building bricks to touch the situation producing short circuit occurring, guarantee the safety in utilization of the miniature fixed resistor of the embodiment of the present invention accordingly in time installing other electronic building bricks.
And the overall appearance of the miniature fixed resistor of the embodiment of the present invention can be become by the coating form of described resistive coating 50 as shown in Figure 3 as the outward appearance of clavate resistance, but, due to coated in described resistive coating 50 be the minimum described shape resistance of volume, thus significantly can reduce overall volume.
With product on the market, with the clavate resistance of same nominal power 1W (Watt) and sheet shape resistance, the outward appearance with 1W clavate resistance is about long 11.5mm, the cylinder (volume about 63.6 cubic millimeters) of diameter 4.5mm, and the outward appearance of the sheet shape resistance of 1W is about long 6.3mm, wide 3.2mm, the square plate body structure (volume is about 11 cubic millimeters) of high 0.55mm, under same nominal power, the volume of sheet shape resistance is significantly less than the volume of clavate resistance, as can be seen here, under the specification of same nominal power, the volume of the miniature fixed resistor of the embodiment of the present invention is significantly less than clavate resistance, and the installation of plug-in type is carried out by pin described in two 40, except being applicable to the utilization of microminiaturized product, more can improve the convenience of use, and the rated power needed for maintaining.
On the other hand, if with regard to the resistor of same volume, because the outer coating of of the present invention shape resistance 30 arranges described resistive coating 50, the area of dissipation of overall electrical resistance device can be improved by described resistive coating 50, the basis of original shape resistance 30 possesses the rated power of described shape resistance 30, and under applying the situation of described resistive coating 50 again outside sheet shape resistance 30, except improving area of dissipation, the rated power of overall electrical resistance device can be increased again simultaneously, accordingly, in the resistor specification of same volume, the miniature fixed resistor of the embodiment of the present invention can provide compared to the higher rated power of general resistor, improve the applicability of the embodiment of the present invention accordingly.
