Abstract

The utility model relates to a ring choker whose coil is coiled into ring. An iron core is composed of a plurality of chip laminated layers (7) with inner bayonets; the upper part and the lower part of the chip laminated layers (7) is relatively inserted on a ring coil (4); a non-magnetic gap (8) is arranged between two relative chip laminated layers. The ring choker of the structure has simple manufacturing technology, and only requires ordinary devices, dispensing with special devices. The ring choker solves the problem that the existing ring choker has great producing difficulty; consequently, the cost is reduced; the producing efficiency is enhanced.

Description

The annular choke

The utility model relates to the structure that choke comprises ballast, relates to the structure of annular choke iron core and coil in more detail.

Existing annular choke all is the coiling iron core formula, its structure as shown in Figure 1, coil 1 is looped around on the annular core 2, is non magnetic gap 3 between the plurality of sections iron core of looping iron core 2, and the annular choke of this structure has very big difficulty on manufacturing process:

1, aspect fabrication of iron core

(1) silicon steel sheet must be cut into the fillet of required width, so just need bulky cutting machine;

(2) the fillet silicon steel sheet must be wound into annular, so just need complicated iron core volume ring machine;

(3) annular core must be cut off so that form a non-magnetic gap in iron circuit, so just need the higher metal cutter of precision.

2, aspect the coil making

(1) annular core of band gap closely must be wrapped one deck insulating paper, so that make the good insulation performance layer be arranged between coil and the iron core, this is one time-consuming operation;

(2) must on the annular core of wrapping, coil, so expensive and inefficient special-purpose annular core coil winding machine with regard to needs.

Cause the big basic reason of above-mentioned technology difficulty to be the loop configuration of iron core, making annular core difficulty is big, and coiling is also very difficult on annular core.

The purpose of this utility model is to solve the big problem of ringlike induction ballast producting process difficulty by the structure that changes ringlike induction ballast, thereby reduces cost, and enhances productivity.

The utility model is made up of iron core and coil, and wherein the coil spiral circularizes, and the iron core setting is fixed on the loop coil, and iron circuit is provided with non-magnetic gap.

Above-mentioned coil generally is wound on the loop coil skeleton, and to form loop coil, the loop coil outer surface is coated with insulating barrier.

Above-mentioned iron core can be the monoblock iron core, also can be made up of the plurality of chips lamination, and iron core is upper and lower to be inserted on the loop coil relatively, leaves the gap between upper and lower relative two iron cores, to form non-magnetic gap.The chip of above-mentioned formation chip-stack can be the U-shaped chip of bayonet socket in the band, can divide behind the horizontal closed assembly of this U-shaped chip folded upper and lowerly to be inserted on the loop coil relatively; Said chip also can be the flute profile sheet, and branch is folded upper and lower behind the upper and lower suit successively of flute profile chip from small to large is inserted on the loop coil relatively.

Install on loop coil reliably for iron core, iron core can be fixed on the loop coil by modes such as plastic packaging, fixed mounts.

The annular choke of this structure is extremely simple on manufacture craft:

1, aspect the coil making

Inject the loop coil skeleton of insulation earlier, just can on this skeleton, lay out loop coil, coat one deck insulating material at coil surface then with common coil winding machine, as insulating tape, the loop coil skeleton can be insulating material such as plastics, and like this, the loop coil surface is insulated material and coats.

2, aspect fabrication of iron core

(1) only needs common punch press stamping-out to go out the chip of bayonet socket in the band, be inserted on the loop coil relatively chip-stack up and down then;

(2) by cutting out some paper-like materials, pad just can form non-magnetic gap on the loop coil between the two folded relative chip-stack.

The utility model compared with prior art has following advantage:

1, simple, the manufacturing easily of technology;

2, equipment is simple, only needs some common equipments, and does not need special equipment.

Fig. 2 is the structural representation of the utility model annular choke.

Fig. 3 is the A-A face cutaway view of annular choke shown in Figure 2.

Fig. 4 is the U-shaped chip that constitutes chip-stack shown in Figure 2.

Fig. 5 is inserted into structural representation on the annular line chart up and down relatively by two chip-stack that U-shaped chip shown in Figure 4 constitutes.

Fig. 6 is the flute profile chip that constitutes chip-stack shown in Figure 2.

Fig. 7 is the upper and lower structural representation that is inserted into relatively on the loop coil of two chip-stack that is made of flute profile chip shown in Figure 6.

The utility model is described in further detail below in conjunction with implementing side and accompanying drawing.

As Fig. 2, shown in Figure 3, coil is wound on and forms loop coil 4 on the loop coil skeleton 5, outer surface at loop coil 4 coats an insulating barrier 6, chip-stack 7 is inserted on the loop coil 4 up and down relatively, leave non-magnetic gap 8 between the upper and lower two relative folded chips, iron core is fixed as one by plastic packaging mode and loop coil 4.

As shown in Figure 4 and Figure 5, divide folded being inserted on the loop coil 4 behind the horizontal closed assembly of U-shaped chip.

As shown in Figure 6 and Figure 7, divide folded being inserted on the loop coil 4 behind the flute profile chip suit that varies in size.
