CN2618275Y - Winding ballast with frameless coils - Google Patents

Abstract

The utility model relates to a ballast with a winding without a framework, comprising a winding, a steel core, a terminal and a mount bracket. The winding is supported without the framework. In addition, a mold which is wound around the winding without framework is designed. The mold comprises a base, a sliding pellet and a movable stop block. Because the winding of the ballast is not provided with the framework, the ballast is dipped more thoroughly, which is useful for reducing the noise and improving the insulation performance. The safety is also enhanced. The product has a compact structure and smaller volume.

Description

Exoskeletal winding ballast

Technical field

The utility model belongs to the electric light source technology field, is specially the exoskeletal ballast of a kind of coil windings.

Background technology

Ballast is the important component part of various decorations, illuminating lamp (as fluorescent lamp, metal halide lamp, neon light etc.).Common iron core ballast, its winding part is made up of solenoid and support framework (comprising end tube), and promptly coil winding is seen shown in Figure 1 on support framework.This ballast will be because the existence of skeleton will cause adverse effect to product quality.For example, the stress of skeleton will cause dielectric strength to descend, and particularly the thick line winding is even more serious; And the skeleton wall of thick line winding increases, and the electric wire capacity is reduced, and volume increases; Coil winding is inhomogeneous, causes voltage between layers to become big, burns out easily, influences useful life.

Summary of the invention

The purpose of this utility model is to propose the exoskeletal ballast of a kind of winding, avoids skeleton to the adverse effect that product quality causes, and guarantees the stable of quality.

The ballast of the utility model design is made up of mounting bracket, iron core, winding and junction block, as Fig. 2-shown in Figure 3.Wherein, the exoskeletal supporting of winding, the structure of remaining part is identical with common ballast with matching relationship, between winding and the iron core insulating paper is arranged.

Manufacture method of the present utility model is as follows:

According to the specification requirement of winding, design coiling mould.This coiling mould constitutes the inboard shape of the coil of pellet profile and required coiling, consistent size by pedestal, slip pellet, the mobile block of tape spool.The slip pellet can be installed on the axle of pedestal, and mobile block can be enclosed within axle head, and pellet is blocked.The mould that will wind the line during coiling places on the special-purpose coiling lathe, with row around the mode coiling.

By behind the good coil of design specification coiling, shed mobile block, the slip pellet moves inward under the extension spring effect, and coil windings is taken off from the coiling pellet, sees shown in Figure 4.Then, on coil, wrap insulating paper, insert lamination, carry out argon welding, dipping by common technology.The structure of remaining part and assembly technology etc. are similar with common ballast.

The ballast of the utility model design has following characteristics:

1, removed skeleton, the insulation between winding and the iron core is guaranteed by insulating paper, and the ballast fail safe is improved.

2, remove skeleton after, flood more thoroughly, help reducing noise, improve insulation property.

3, the method for winding of coil be row around, turn-to-turn voltage is reduced.

4, compact conformation, volume-diminished.

Embodiment

Further describe the utility model below by embodiment.

Embodiment:

With reference to the accompanying drawings.Make the ballast of 250W metal halide lamp.Coil windings 1 as shown in Figure 4, exoskeletal supporting, its inboard width is 30.7mm, length is 57.5mm, wire gauge is Q (ZY/XY)-2-0.75, row is insulating paper 5 of outer bag around, winding two ends, layer of transparent adhesive tape 6.Lead-out wire is warded off tin, and wherein, the 1S end is 80mm, and 1C is 25mm, and 1F is 35mm, all is with silicone rubber sleeve 8.The mould of coiling as shown in Figure 3.Constitute the inboard shape and the consistent size of the profile of pellet 10 and size and coil by pedestal 9, slip pellet 10, mobile block 11.Coiling on special use coiling lathe.After coiling finishes, coil windings is unloaded from mould, wrap insulating paper 5 and adhesive tape 6, insert iron core 2.The structure of iron core 2 is similar with routine.Through argon welding, dipping.Winding 1, iron core 2 are installed on the support 4 by hex nut 7, and the overall dimension of ballast is long 110mm, wide 93mm.Weldering knot binding post 3 on shell, the lead-out wire of coil 2 connects binding post 3.Promptly get required ballast through encapsulation.

Claims (1)

1, a kind of exoskeletal winding ballast is made of winding (1), iron core (2), binding post (3), mounting bracket (4), it is characterized in that the exoskeletal supporting of winding (1), between winding (1) and the iron core (2) insulating paper is arranged.
