Abstract
The utility model discloses a novel magnet ring transformer used for an electronic ballast, which belongs to energy-saving lamp electronic ballasts. Particularly, the novel magnet ring transformer comprises a magnet ring and a printed circuit board used for replacing connecting wires, wherein the printed circuit board is E-shaped, the middle supporting leg is inserted into the magnet ring, and two lateral supporting legs are clamped on two sides of the magnet ring. By adopting the technical scheme, a traditional magnet ring transformer is divided into two independent elements, namely a separate magnet ring and a printed circuit board used for replacing original conducting wires, thereby realizing the quality control of the separate magnet ring and convenient assembly of the whole magnet ring transformer. The novel magnet ring transformer provided by utility model has the benefits that the structure is reasonable; magnet ring after test can be mounted conveniently in the printed circuit board; the appearance is beautiful and elegant; and the connection with an electronic circuit in an energy-saving lamp is convenient.
Description
Technical field
The utility model relates to the transformer that uses on a kind of electricity-saving lamp and the electric ballast, specifically is a kind of magnetic ring transformer.Be particularly suitable for the electric ballast of stand alone type, discrete device.
Background technology
At present, in environmental protection, energy-conservation and green illumination product, electricity-saving lamp and fluorescent lamp are serving as main role, use by electricity-saving lamp and fluorescent lamp, can save a large amount of energy, reduce exhaust gas discharging, thereby alleviate greenhouse effect, when throwing light on as the Time for Sunshine, farthest alleviated pollution environment.And to light above-mentioned fluorescent tube, need corresponding ballast.
Existing ballast has two kinds of forms, and a kind of is Inductive ballast, and another kind is an electric ballast.Because the Inductive ballast loss is big, not energy-conservation, and volume is big, and in the electricity-saving lamp of can't packing into, so be eliminated substantially, it is lighted for real matched energy saving lamp and fluorescent lamp and what work is electric ballast.
Electronic circuit in electricity-saving lamp part and independently in the electric ballast, magnetic ring transformer is a very crucial and important element, is the core of ballast and electricity-saving lamp.It has determined to light operating frequency, the driving force of lamp, even has determined lamp and ballast reliability of products.Magnetic ring transformer is commonly called as ballast and electricity-saving lamp " heart ", in entire circuit, its number of turn, the sectional area of the turn ratio and magnet ring etc. has determined the operating frequency of electricity-saving lamp and ballast substantially, the driveability of circuit played cause pass importance, and driving is strong if directly affect the Performance And Reliability of entire circuit, and above-mentioned performance, mainly determined by the magnet ring parameter in the magnetic ring transformer, the inductance value of its middle magnetic ring, initial magnetic permeability, remanent magnetism, rectify object for appreciation power and saturation flux density, and the weighted average (that is: multi-stress) of above-mentioned parameter composition all directly affects the performance of entire circuit, and the Curie temperature of magnet ring and magnetic hysteresis loop also are the principal elements that influences circuit, and the test of these parameters and control, must use relevant tester that magnet ring is directly tested, and the magnetic ring transformer of buying, to its above-mentioned parameter test the time, many restrictions and inconvenience are arranged.Therefore, magnet ring must be separated from magnetic ring transformer, so just can be carried out comprehensive parameter testing magnet ring.
Existing magnetic ring transformer structure magnet ring and many element legs are arranged, and the element leg is made up of flexible conductor as shown in Figure 1, and is very inconvenient in the ballast assembling process, influences efficiency of assembling.And inconvenience is carried out comprehensive parameter testing to magnet ring.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of novel magnetic ring transformer, and the tactic pattern of magnetic ring transformer is improved, and both convenient control to the magnet ring quality is convenient to again install, and has improved production efficiency.
The utility model is realized with following technical scheme: a kind of novel magnetic ring transformer, comprise magnet ring, it is characterized in that also comprising as substituting and connect the printed substrate that lead is used, be printed with the printed wire that substitutes former lead thereon, printed substrate is an E shape, middle supporting leg is inserted in the magnet ring, and the supporting leg of both sides is stuck in the both sides of magnet ring.
Owing to adopted technique scheme, traditional magnetic ring transformer two independently elements have been resolved into, be independent magnet ring and in order to substituting the printed substrate of original lead, to realize to the quality control of independent magnet ring with to the facility assembling of whole magnetic ring transformer.
The beneficial effects of the utility model are, and are rational in infrastructure, and the magnet ring that test is good can be packed in the printed substrate very easily, and appearance looks elegant is generous, being connected of convenient and electronic circuit that electricity-saving lamp is interior.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is traditional magnetic ring transformer structural representation;
Fig. 2 is the utility model structural representation;
Fig. 3 printed substrate structure schematic diagram;
Fig. 4 is the utility model scheme of installation.
Among the figure: 1, magnet ring, 2, printed substrate, 2-1, middle supporting leg, 2-2, two side legs, 2-3, printed circuit, 3, the ballast printed circuit board (PCB).
Embodiment
As shown in Figure 2, a kind of novel magnetic ring transformer is made up of magnet ring 1 and printed substrate 2.
As shown in Figures 2 and 3, printed substrate 2 is an E shape, is printed with the printed wire 2-3 that substitutes former lead thereon.Middle supporting leg 2-2 is inserted in the magnet ring 1, and the supporting leg 2-1 of both sides is stuck in the both sides of magnet ring.Printed substrate 2 thickness are 0.8-1.6mm, and material is cardboard, half glass plate or FR4 plate.Printed wire 2-3 on it requires to draw the figure that sets type to coil turn and line principle according to circuit, will draw good composing figure then and be made into printed substrate.
As shown in Figure 4, during use, magnet ring and printed substrate are directly packed in the ballast printed circuit board (PCB) 3.
Claims (2)
1. novel magnetic ring transformer, comprise magnet ring (1), it is characterized in that: also comprise printed substrate (2), on printed substrate (2), be printed with Copper Foil printed wire (2-3) with lead function, printed substrate (2) is an E shape, middle supporting leg (2-2) is inserted in the magnet ring, and the supporting leg of both sides (2-1) is stuck in the both sides of magnet ring.
