With the adoption of the technical scheme, compared with the prior art, the wires of the magnetic bead comprise the soft wire cores made of aluminum materials, and the outer surfaces of the wire cores are coated with the tin layers; when the magnetic bead is processed, the wires are coated with the tin layers, so that the paint scrapping and tin coating procedures can be omitted, and the processing is convenient; and meanwhile, the wire cores are soft, so that the wires are convenient to penetrate, the labor intensity of a worker can be reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of magnetic bead.
Background technology
Magnetic bead can be used in Inhibitory signal line, high-frequency noise on power line and spike disturb, the role who plays the part of alternating-current resistance, this device can allow direct current signal to pass through, and filtering AC signal, it generally comprises and is provided with the ferrite of penetrating wire perforation and is located in the wire in guiding perforation, while having electric current to pass in wire, ferrite does not almost have any impedance to low-frequency current, and can produce compared with high attenuation effect the electric current of upper frequency, high-frequency current distributes with form of heat therein, its equivalent electric circuit is an inductance and a resistance series connection, the value of two equivalent elements is all proportional with the length of magnetic bead, and with wire square relevant through ferritic number of times.
Existing a kind of magnetic bead as depicted in figs. 1 and 2, on ferrite 91, have a plurality of wire perforation 911, wire is enamel covered wire 92, during processing magnetic bead, enamel covered wire 92 can be located in many ways in hole and pass number of times to obtain different wires, thereby obtains different impedances.Enamel covered wire 92 has and is connected to two corresponding lead perforation 911 axially with the cross-over connection sections 921 of one end, and the two ends of enamel covered wire 92 is stretched out in ferrite 91 outsides, as pin.Because the core of enamel covered wire 92 is to be made of copper, material is harder, more difficult bending, so threading is more difficult, has affected production efficiency; And can only be bent into inverted U-shaped across the stage 921, its distance from top ferrite 91 distant, easily to sideshake, for preventing that cross-over connection section 921 from relatively swinging and causing short circuit between adjacent cross-over connection section 921 while having multistage, and then preventing that enamel covered wire 92 from reducing through the number of times of ferrite 91 the impedance reduction causing, there is enamelled coating the outside of core.For realizing, be connected with the good of circuit, after enamel covered wire 92 threading complete, its pin need to be scraped paint operation, then wards off tin, complex procedures, and labor strength is large, and production efficiency is low.In addition, when a large amount of production, for example, have the three-phase kilowatt-hour meter manufacturing enterprise of a large amount of magnetic bead demands, the problems referred to above are more outstanding, and equipment, raw material, cost of labor are all higher, make magnetic bead be processed into production bottleneck.
Utility model content
The purpose of this utility model is to provide a kind ofly can save scraping paint and warding off the magnetic bead of tin operation in production process.
The technical solution adopted in the utility model is: a kind of magnetic bead, comprise and be provided with the ferrite of wire perforation and be located in the wire in ferrite, described wire has and is connected to two corresponding lead perforation axially with the cross-over connection section of one end, described wire comprises the soft core that aluminum is made, and the outer surface of described core is enclosed with tin layer.
Described cross-over connection section is configured to end face near adjacent across the domes that are in contact with one another between the stage to reduce.
Described wire is tin alclad line.
The utility model adopts technique scheme, and compared with prior art, the wire of magnetic bead comprises the soft core that aluminum is made, the outer surface of described core is enclosed with tin layer, during processing magnetic bead, because wire outside has been provided with tin layer, therefore can save and scrape paint and ward off tin operation, easy to process.Meanwhile, because core is softer, so threading is convenient, can alleviate labor strength, enhances productivity.

Fig. 1: a kind of structure of magnetic bead and threading mode schematic diagram in prior art;
Fig. 2: a kind of another kind of threading mode schematic diagram of magnetic bead in prior art.
The name that in figure, each Reference numeral is corresponding is called: 91 ferrites, 911 wire perforation, 92 enamel covered wires, 921 cross-over connection sections.
Fig. 3: a kind of structural representation of magnetic bead in the utility model.
The name that in figure, each Reference numeral is corresponding is called: 1 ferrite, 2 tin alclad lines, 21 cross-over connection sections, 22 pins.
Embodiment
An embodiment of a kind of magnetic bead of the utility model as shown in Figure 3, comprises and is provided with the ferrite 1 of wire perforation and is located in the wire in ferrite 1.Wherein wire is tin alclad line 2, comprises the aluminum soft core of making and the tin layer that is included in core outer surface.
Tin alclad line 2 is to wear in corresponding wire perforation by the requirement of setting, after tin alclad line 2 threading complete, tin alclad line 2 forms and is connected to the axial cross-over connection section with one end of two corresponding lead perforation, during 2 tension of tin alclad line, the part being in contact with one another between the opening's edge of cross-over connection section 21 and two guiding perforation corresponding end openings forms compression fit, can complete the processing of magnetic bead, like this, cross-over connection section 21 forms to ferritic end face near adjacent across the domes that are in contact with one another between the stage to reduce, these domes are with respect to the inverted U-shaped of existing magnetic bead, the distance of domes top and ferrite 1 corresponding end-faces is very little, the cross-over connection section 21 of domes there will not be larger swing, therefore can avoid being short-circuited between adjacent cross-over connection section 21, thereby avoid affecting the impedance of magnetic bead.And the existing tin layer of pin 22 outer surfaces of tin alclad line 2, can be directly and circuit welding, so can save of the prior art scraping and paint and ward off tin operation.Meanwhile, tin alclad line 2 materials are softer, and threading is convenient, can alleviate labor strength, enhances productivity.
Adopt the magnetic bead in the utility model, empirical tests, the magnetic bead quantity of workman processing in one hour can be brought up to 500 by original 125, operating efficiency improves nearly 4 times, can solve production bottleneck problem, and can save a large amount of labour costs, in addition because the price of tin alclad line is lower than enamel covered wire, therefore also can save a large amount of material costs.
In the above-described embodiments, what wire adopted is tin alclad line 2, and in other embodiments, wire also can adopt outer surface to be enclosed with the aluminum steel of tin layer.
