Abstract
The utility model discloses a fuse base overload protection combined structure which comprises a fuse base body and a pair of lead wires penetrating through the base body. Lead wire pins are formed at the upper parts of the lead wires, which penetrate through the base body; a group of fuse wires are clamped on the lead wire pins; and at least one recessed groove is arranged between the lead wire pins on the base body. According to a base of a miniaturized fuse, a supplementary structure ensuring to cut an overload current is improved in the technical scheme, and one or more recessed grooves are formed between the lead wire pins after the size of the fuse is reduced, so that the distance of an edge surface between the two lead wire pins connected with the fuse wires is increased, therefore, the miniaturized fuse can meet electronic safety standards.
Description
Technical field
The utility model relates to the overload protection combining structure of electronic devices and components, particularly a kind of pedestal of fuse, and this fuse base mainly is at after the fuse microminiaturization, can make microminiaturized fuse can meet the electronic security(ELSEC) standard.
Background technology
At present; the structure of fuse as depicted in figs. 1 and 2; the critical piece of this fuse is a kind of fuse 30; be welded in the circuit that is required to insure; when the electric current that flows through fuse 30 surpasses the value that is provided with; fuse 30 fusing; protected circuit is opened circuit herein; other components and parts in this circuit of success protection are owing to electric current damages too greatly; therefore, fuse generally is to be model with the current value set, such as the fuse of 5A; the fuse of 3A etc.; for fuse itself is protected, at present, fuse is arranged on the pedestal; the structure of pedestal as depicted in figs. 1 and 2; comprise a base body 10, base body 10 is provided with a pair of lead-in wire 20 that runs through this base body 10, this is flattened 20 the end of going between form pair of lead wires pin 21; insert and put one group of fuse 30 at terminal pin 21 again, by lid base body 10 complete upper shields are formed a complete fuse again.This fuse is generally used for protecting the electronic loop between the electronic equipment, reduces noise, as various power-supplying circuits such as power supply device, charger for mobile phone, office or the automation equipment in factory of electronic game machine and household electrical appliance.In such use, the power supply circuit of littler thinner electronic game machine is just continuing to grow up with the demand of charger for mobile phone, in order to adapt to the needs in market, various types of electronic components are all in further miniaturization, therefore, need the littler fuse of volume, still, if the fuse of present this structure further will cause connecing the creepage distance shortening of establishing between the pair of pins 21 of organizing fuse 30 after the miniaturization, finally cause to meet some national desired electronic security(ELSEC) standards.
The utility model content
If the utility model shortens for the creepage distance that the fuse that solves present this structure further will cause connecing between the pair of pins of establishing fuse after the miniaturization; finally cause to meet the deficiency of some national desired electronic security(ELSEC) standards, a kind of fuse base overload protection combining structure is provided.
The utility model for the technical scheme that realizes its technical purpose and adopt is: a kind of fuse base overload protection combining structure comprises the fuse base body and runs through the pair of lead wires of described base body; Described lead-in wire runs through the base body top and partly forms terminal pin, inserts and puts one group of fuse on the described terminal pin; At least be provided with a recessed groove on the described base body between the terminal pin.
Further, in above-mentioned a kind of fuse base overload protection combining structure: on described base body, be provided with a recessed groove or multiple recessed groove between the paired terminal pin.
In the technical solution of the utility model at the fuse base after the fuse microminiaturization to guaranteeing to block the supplementary structure improvement after the overload current, after size is dwindled, make and form one or multiple recessed groove between the terminal pin, the creepage distance that connects between two terminal pins establishing fuse is increased, allow fuse after the microminiaturization can meet the requirement of electronic security(ELSEC) standard.
