Description
Technical field
The utility model is related to technical field of electronic components, more particularly to a kind of fixed metal foil of extraction electrode spacing
Resistor.
Background technology
The existing metal foil resistor lead for using at present directly leads out hull outside, and lead spacing is not easily controlled, partially
Difference is larger；When lead is subject to external stress, understands some stress and be delivered to resistor chip internal, resistance is produced certain
Influence.
The utility model patent of Patent No. CN200720025044.5, discloses a kind of electronic scale weighing sensor gold
Category paper tinsel temperature-compensated resistor, the resistor outer lead is fixed on the back side of resistance chip after being connected with packing ring, but described
Packing ring is in contact with outer lead, on the one hand can influence the resistance of resistance chip due to being not provided with insulating barrier on packing ring；On the other hand
The position of packing ring cannot be fixed, and make the spacing of lead uncontrollable, structural instability.
The content of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of fixed metal foil resistor of extraction electrode spacing
Device, efficiently solves the problems, such as that current metal foil resistor extraction electrode spacing is uncontrollable, extraction electrode intensity is not enough, the gold
Category paper tinsel resistor with the addition of copper-clad plate pad on two extraction electrodes of existing resistor, and extraction electrode is penetrated copper-clad plate pad
Through hole in and it be weldingly fixed on the bottom of foil and substrate, to solve the problems, such as that lead spacing is not easily controlled,
Extraction line strength is increased simultaneously, makes the structure of resistor and resistance more stable.
The utility model solves the technical scheme that its technical problem used：The fixed metal of extraction electrode spacing
Paper tinsel resistor, including foil, substrate, the lead that housing and enclosure interior are set, it is characterised in that lead is from top to bottom by pasting
Close section and draw section and constitute, the laminating section is pasted onto the back side of substrate by ultraviolet glue, and the top of section of fitting passed through
Lead is crossed to be welded with foil；The extraction section is connected with copper-clad plate pad, and copper-clad plate pad is set to cuboid, copper-clad plate pad
Surface is provided with green welding resistance insulating barrier, and the two ends of its upper surface are symmetrically arranged with pad, and the upper surface of pad is provided with spray tin
Layer, pad is provided centrally with through hole.
The foil and substrate bottom are welded with the upper surface of copper-clad plate pad.
The upper plane for drawing section is concordant with the upper surface of pad to be set.
The beneficial effects of the utility model are that the metal foil resistor that the utility model is set draws for two in existing resistor
Go out on electrode with the addition of copper-clad plate pad, extraction electrode is penetrated in the through hole of copper-clad plate pad and it is weldingly fixed on
The bottom of foil and substrate, solves the problems, such as that lead spacing is not easily controlled, while increased extraction line strength, makes resistor
Structure and resistance it is more stable；The spray tin layers that the upper surface of pad is set serve anti-oxidation, more conducively stable welding；Copper-clad plate
The green welding resistance insulating barrier that gasket surface is set plays insulating effect, makes the electric current on extraction electrode not by the shadow of copper-clad plate pad
Ring, make the resistance of resistor more stable.
