Abstract
The utility model relates to an improve structure of an iron core of fluorescent lamp ballast. The structure of the iron core is formed by the crossing stack of a stem whose two flat yokes are of different length (comprising two yokes) and an oblique E-shaped iron core punched chip whose two yokes are respectively provided with convex-concave seam. The utility model which adopts the structure of the iron core has the advantages of low magnetic leakage, low noise, low cost, easy machining and easy manufacture.
Description
The utility model relates to the improvement of the core construction of electric inductance type fluorescent lamp ballast.
The electric inductance type fluorescent lamp ballast mainly constitutes by iron core with coil.Core construction has following several (referring to number of patent application 90205208.X, title " a kind of electric inductance type fluorescent lamp ballast iron core of new structure ") in the prior art:
(1) stamen formula iron core.
(2) shell-type iron core.
(3) has the fixedly shell-type iron core of magnetic gap.
(4) by flat two yokes of stamen post tiltedly or the two yokes oblique E shape sheet that is uneven in length intersect the repeatedly shell-type iron core of dress.
(4) plants iron core is better than first three kind iron core, but easily makes the iron-core lamination dislocation and the damage coil windings when laminate patch and adjusting electric current; Because leakage field is bigger, noise is bigger sometimes on the other hand.
The utility model has improved the deficiency of prior art (four).
As shown in Figure 1, the iron-core lamination (1) that the iron core of electric inductance type fluorescent lamp ballast (13) is uneven in length (comprising that two yokes are oblique) by flat two yokes of stamen post and two yokes have Convex Joint (4) and recessed seam (3) respectively intersects repeatedly to adorn and forms.Convex Joint (4) and recessed seam (3) can be half garden shape (containing half ellipse garden shape) (see figure 1) or triangle (see figure 2)s.The core limb middle part is magnetic gap (2), the size that the size of adjusting magnetic gap (2) can be regulated electric current.In the window unshakable in one's determination coil windings (5) is arranged, the lead-out wire (12) of the two ends of winding through passing conduit (11) joins with external circuit.Have the insulation framework (6) and the insulation scraps of paper (7) to be separated by between coil windings (5) and the iron core, shell (9) and cover plate (10) play fixing and thermolysis.
Because the Convex Joint (4) of iron-core lamination (1) two yoke and the effect that recessed seam (3) has the location do not cause punching dislocation up and down when laminate patch and adjusting electric current, reduce percent defective decline so damage the possibility of coil windings.The convex-concave seam is bigger than the length of linear joint in addition, so have the advantage that long seam leakage field is little, noise is low.Groove (8) can be set in the ballast of having relatively high expectations, compress iron core, thereby noise is further reduced so that penetrate screw rod.
Claims (3)
1, new construction fluorescent lamp ballast, it comprises by punching (1) intersection with Convex Joint (4), recessed seam (3) and groove (8) repeatedly adorns the iron core with magnetic gap (2) (13), coil windings (5), conduit (11), lead-out wire (12), skeleton (6), the insulation scraps of paper (7), shell (9) and the cover plate (10) that forms, it is characterized in that: punching (1) has Convex Joint (4) and recessed seam (3), and the stamen post of (13) unshakable in one's determination has magnetic gap (2).
2, fluorescent lamp ballast according to claim 1 is characterized in that: the Convex Joint (4) of punching (1) and recessed seam (3) are half garden shape (containing half ellipse garden shape).
3, fluorescent lamp ballast according to claim 1 is characterized in that: the Convex Joint (4) of punching (1) and recessed seam (3) are triangle.
