Description
Technical field
The present invention relates to a kind of inductor, the inductor particularly on electricity-saving lamp and LED.
Background technology
At present, the developing direction of transformer, for reducing volume, reduces costs, miniaturized, slimming.After typical transformer stitch dish line, upper tin, welding, solder joint is higher, affects the setting height(from bottom) of product, separately because this product requirement is miniaturized, there is the situation that safety distance is not enough, easily causes high-voltage breakdown to make property and personal safety can not get ensureing.
Summary of the invention
Technical problem to be solved by this invention is just to provide a kind of EE type inductor, enhances product performance, and ensures the distance of primary and secondary safety, meets the safety requirement of product, reduce costs simultaneously.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of EE type inductor, comprise coil rack and the magnetic core fixing with coil rack one, described magnetic core is EE type, described coil rack is provided with coil groove, coil windings is provided with in described coil groove, described coil windings is divided into primary coil winding and secondary coil winding, described coil rack bottom left is provided with row's primary coil winding stitch, bottom described coil rack, right side is provided with row's secondary coil winding stitch, the lead-out wire of described primary coil winding is connected with primary coil winding stitch, the lead-out wire of described secondary coil winding is connected with secondary coil winding stitch, it is characterized in that: the width of described coil rack is 2.5 times of magnetic core width to 3.5 times, in the middle part of described coil groove, the whole circumference of wound coil groove is provided with separation baffles, coil groove is separated primary coil winding wire ring recess and secondary coil winding wire ring recess by described separation baffles, the width of described primary coil winding wire ring recess is greater than the width of secondary coil winding wire ring recess, bottom described coil rack, the left and right sides is provided with pin frame, the wire lead slot of opening is provided with in the middle part of described pin frame, described pin frame both sides before and after wire lead slot are respectively provided with row's stitch, go between from coil windings extraction and be connected with stitch through after this wire lead slot, lead-in wire is fixed in this wire lead slot.
Preferably, described baffle plate is double-decker, is separated between two-layer baffle plate by separation trough.
Preferably, described coil windings adopts copper-clad aluminum conductor to be entwined.
Preferably, before and after bottom described wire lead slot, both sides are provided with stem, go between through the gap between stem and wire lead slot sidewall, are fixed by lead-in wire after the hot melt of stem top.
By changing coil skeleton structure in the present invention, by original coil rack by widening, making the long-pending increase of core cross section, improving AE.And adopt copper-clad aluminum conductor to reduce copper cash consumption.Be fixed on by lead-in wire in wire lead slot, what cut the interlayer adhesive tape of same winding and line wraps up in an adhesive tape, and for using automaton coiling to provide possibility, use automaton to enhance productivity, reduction product cost, ensures the quality of products, alleviate artificial dependence.
In addition, by the structural adjustment of coil rack, coil groove is designed to two line of rabbet joint groove designs not of uniform size, make armature winding around in the relatively wider groove of wire casing, make secondary winding around in the relatively narrower groove of wire casing, and use multi cord coiling, the elementary and secondary baffle plate having again skeleton itself to be with, so just avoid the safety requirement for reaching primary and secondary winding, use side control adhesive tape and the requirement of reflexed adhesive tape.Add this skeleton and have a supporting shell, avoid core to reach safety requirement by the mode of operation of gum, save cost of labor like this and improve production efficiency.
In a word, the invention has the beneficial effects as follows: core cross section is long-pending to be increased, and improves AE and enhances product performance, ensure the distance of primary and secondary safety, avoid use side control, finally reach the object reducing cost of labor, the safety meeting product requires and improves the total quality of product.
