Beneficial effect:
The utility model power-type paster fusing resistor product; can use as common patch resistor under circuit normal condition; but working as has abnormal conditions to occur in circuit; during such as unexpected overvoltage or overcurrent; this product can fuse rapidly oneself, disconnecting circuit thus the safety of protecting complete machine, reduces bigger loss; after abnormal conditions find out eliminating, after only need to changing this product, circuit can recover normal.
Brief description
Fig. 1 is structural representation of the present utility model.
1-shell, 2-plated film ceramic rod resistance unit, 3-cutting, the tin plating chapeau de fer of 4-, 5-copper extraction electrode, 6 be flux ring.
Detailed description of the invention
In order to illustrate the technical solution of the utility model and technical purpose, below in conjunction with the accompanying drawings and the utility model is described further by specific embodiment.
A kind of power-type paster fusing resistor as shown in Figure 1, including plastic shell 1 and the plated film ceramic rod resistance unit 2 being arranged in shell 1.
The two ends of described plated film ceramic rod resistance unit 2 are provided with tin plating chapeau de fer 4, described tin plating chapeau de fer 4 is connected with copper extraction electrode 5, described copper extraction electrode 5 stretch out shell 1 part flatten after along shell 1 external surface shape bending, the outer surface of shell 1 is provided with the projection blocking two bronze medal extraction electrode ends.
Described plated film ceramic rod resistance unit 2 conductive film layer periphery is provided with on flux ring, and film layer and is machined with cutting, and described flux circling point is on the position arranging cutting.Described cutting is thread groove, and processing is in the middle part of resistance unit.
The production process of the utility model power-type paster fusing resistor product includes forward and backward two procedures, its preceding working procedure can use Conventional alloys film resistor production technology, concrete early stage flow process is: cylinder ceramic rod → vacuum sputtering masking → pressure cap → cutting → spot welding, after spot welding completes, using plastic package process that resistor is transferred to SMD technique to produce, idiographic flow is: some flux → plastic packaging → pin forming → plating → mark → test → packaging.
In above-mentioned technique:
1) putting flux: use unleaded fusing agent to be flux material, described flux ring uses resistor colour circle wheel manufacture craft to realize；
2) plastic packaging: designing corresponding plastic package die according to product size, use plastic packaging machine can be integrated for product plastic packaging fusing resistor；
3) pin forming: use the step that automatic forming machine carries out pin flattening, cut-out and bending, forms the extraction electrode molding procedure of paster fusing resistor；
4) electroplate: by pin copper facing, nickel plating or the plating processing such as tin plating, making resistor reach the product with good welds performance；
5) product after electroplating is marked, tests, braid institutional operation, uses automatic laser marking, resistance to measure and braid completes the operation of the mark of product, test and packaging.
The present embodiment is designed to SMD technique power-type fusing resistor, it is simple to SMT operation, reduces the action of manual plug-in unit, can improve operating efficiency.
The present embodiment resistor product has a few place to need the key point of control: 1) selection of cylinder ceramic rod is different from normal alumina porcelain, will select the ceramic rod of about 60% aluminum content；2) for ensureing the uniformity of follow-up operating chacteristics when being cutting, the groove number of turns of product cutting need to control 1 circle above to 2 enclose between be advisable and adjust groove in the product between position；3) it is the operation increasing by one flux before plastic packaging, to ensure the consistent of product operating chacteristics.
Of the present utility model general principle, principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; the utility model is not restricted to the described embodiments; described in above-described embodiment and specification, principle of the present utility model is simply described; on the premise of without departing from the utility model spirit and scope; the utility model also has various changes and modifications, and the utility model claims scope and defined by appending claims, specification and equivalent thereof.
