Technical field
The utility model is related to resistor field, more particularly to one kind without lead line around fusing resistor.
Background technology
As market competition is increasingly fierce, the production cost increases, i.e., to meet that product electrical property improves corresponding production again
Efficiency, therefore demand of the line around fusing resistor Surface Mounting Technology is greatly increased.And traditional insert is substituted with its efficient and stability
Hole electronic component, therefore, invention are a kind of necessary to solve the above problems around fusing resistor without lead line.
Utility model content
The purpose of this utility model is to provide one kind without lead line around fusing resistor, to solve in above-mentioned background technology
The problem of proposition.
To achieve the above object, the utility model provides following technical solution：One kind is without lead line around fusing resistor, bag
Ceramic core is included, resistance wire is wound with the ceramic core, the ceramic core external stability is equipped with electrode cap, is opened on the electrode cap
Equipped with groove, enamelled coating is scribbled on the groove.
Preferably, the number of recesses is arranged on electrode cap for three and uniform intervals.
Preferably, the electrode cap thickness is arranged to 0.2mm.
Preferably, the enamelled coating is made of fire retardant insulating paint material.
Preferably, the electrode cap section is arranged to ellipticity.
The technique effect and advantage of the utility model：0.2mm is arranged to by electrode cap thickness, advantageously reduces electrode cap
Difference of height between ceramic core, resistor main body is smooth after ensureing japanning, easy to absorption of the chip mounter to component, reaches reduction
Material casting rate, improves the purpose of chip mounter production efficiency, by equipped with groove, advantageously ensuring that electrode cap with resistance wire junction not
Because of tension force enamelled coating can be caused to overflow to electrode cap pad, so that influencing patch welding, electrode cap passes through plates process processing again, into
One step strengthens terminal solderability, and the electrode cap welding position is arranged at 1/3rd on the inside of electrode cap both ends, is conducive to weld
Connect firmly, good seal, is hardly damaged.
Brief description of the drawings

The utility model provide as shown in Figs. 1-3 one kind without lead line around fusing resistor, including ceramic core 1, institute
State and resistance wire 2 is wound with ceramic core 1,1 external stability of ceramic core is equipped with electrode cap 3, and electrode cap 3 adds by plating process again
Work, further strengthens terminal solderability, opens up fluted 4 on the electrode cap 3, enamelled coating 5 is scribbled on the groove 4.
4 quantity of groove is arranged on electrode cap 3 for three and uniform intervals, advantageously ensures that electrode cap 3 and resistance
2 junctions of silk will not cause enamelled coating 5 to overflow to 3 pad of electrode cap because of tension force, so that influence patch welding, the electrode cap 3
Thickness is arranged to 0.2mm, is conducive to select the electrode cap 3 for being different from conventional 0.2mm thickness（It is conventional to use 0.25mm）, reduce
Difference of height between electrode cap 3 and ceramic core 1, resistor main body is smooth after ensureing japanning, easy to absorption of the chip mounter to component,
Reach and reduce material casting rate, improve the purpose of chip mounter production efficiency, the enamelled coating 5 is made of fire retardant insulating paint material, is conducive to
Fire retardant insulating, 3 welding position of electrode cap are arranged at 1/3rd on the inside of electrode cap both ends, are conducive to firm welding, close
Seal, be hardly damaged, 3 section of electrode cap is arranged to ellipticity, is conducive to reduce installation thickness.
This practicality operation principle：Electrode cap 3 is processed by plating process again, further reinforcement terminal solderability, on electrode cap 3
Fluted 4 are opened up, enamelled coating 5 is scribbled on groove 4, ensures that electrode cap 3 and 2 junction of resistance wire will not cause enamelled coating 5 unrestrained because of tension force
Overflow to 3 pad of electrode cap so that influencing patch welding, 3 thickness of electrode cap is arranged to 0.2mm, advantageously reduce electrode cap 3 with
Difference of height between ceramic core 1, resistor main body is smooth after ensureing japanning, easy to absorption of the chip mounter to component, reaches reduction
Material casting rate, improves the purpose of chip mounter production efficiency.
Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify the technical solution described in foregoing embodiments, or to which part technical characteristic
