Abstract

The utility model relates to a material-saving-type iron-core ballast, which comprises a wire wrap, a bottom shell and an iron core, wherein, the iron core is composed of L-shaped chips and a T-shaped chip. The utility model is characterized in that buckled openings are arranged on the L-shaped chips. A buckled slot is arranged on the T-shaped chip. Both of the two L-shaped chips are fastened on the buckled slot of the T-shaped chip through the buckled opening to combine into a chip in the shape of two connected squares. The utility model has the advantages of simple and reasonable structure, compact and firm structure, easy fabrication, reliability, practicability, material saving and cost saving.

Description

Material-saving formula iron core ballast

The utility model relates to a kind of ballast, particularly a kind of material-saving formula iron core ballast.

Disclose in the Chinese patent (patent No. 922435294) a kind of " economical inductance type ballast ", its iron core is to piece together " ㄩ " shape in opposite directions by the pair of L-shaped chip, and be combined into a slice T core sheet "

" shape, form with the folded system of the same chip of multi-disc.But there is following shortcoming in it: after the amalgamation "

" shape iron core both sides must wrap up with shell, have expended the material of shell, have increased certain cost; And " " shape iron core two ends are not because of there being detent mechanism, so L shaped chip be easy to come off from the iron core two ends, practical.

It is a kind of simple and reasonable that the purpose of this utility model is to provide, practical reliable, can save the material-saving formula iron core ballast of material and cost.

The purpose of this utility model can reach by following measure: the utility model comprises line bag, drain pan, and the iron core that constitutes by L shaped chip and T core sheet, it is characterized in that: L shaped chip is provided with the button mouth, T core sheet is provided with catching groove, two L shaped chips are fastened on the catching groove of T core sheet by the button mouth, be combined into " " the core sheet.

The purpose of this utility model can also reach by following measure: also be provided with button bit on the L shaped chip, and can be fastened on drain pan by button bit.The both ends of the surface of iron core can establish one deck by T core sheet and " ㄩ " core sheet constitute " " the core sheet.

Fig. 1 is the structural representation of L shaped chip;

Fig. 2 is the structural representation of T core sheet;

Fig. 3 is the combining structure schematic diagram of two L shaped chips and T core sheet;

Fig. 4 is a combining structure schematic diagram of the present utility model;

Fig. 5 is the combining structure schematic diagram of another embodiment of the utility model.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1～Fig. 4, the utility model is made up of other annexes such as line bag 1, drain pan 2, iron core 3 and binding posts.Iron core 3 is by synthetic " ㄩ " shape of two L shaped chipsets, and be combined into a slice T core sheet "

" shape, form with the folded system of the same chip of multi-disc.L shaped chip is provided with button mouth 4, and T core sheet is provided with 5, two L shaped chips of catching groove and is fastened on the catching groove 5 of T core sheet by button mouth 4, be combined into "

" the core sheet; Line bag 1 be loaded on " " in the core sheet.Also be provided with button bit 6 on the L shaped chip, and can be fastened on drain pan 2, form structure as shown in Figure 4 by button bit 6.Owing to adopted above-mentioned fastening structure, so even do not adopt the shell iron core 3 can be not loose, the L shaped chip at iron core two ends can not come off yet yet.

With reference to Fig. 5, for the L shaped chip that guarantees iron core 3 two ends more reliably can not come off, so can establish respectively at iron core 3 two ends one deck by T core sheet and " ㄩ " chip constitute "

" the core sheet, its effect is the L shaped chip in the middle of clamping, and it can not come off from iron core 3 two ends.

The utility model has following advantage compared to existing technology: simple and reasonable, and compactness Firmly, make easily, reliable and practical, saved material and cost.
