Abstract
The utility model discloses an improved structure of a transformer wire rack. The improved structure of the transformer wire rack is composed of a primary wire rack and a secondary wire rack. The edges of the two ends of the primary wire rack are respectively provided a circular baffle, a space where coils are wound is formed between the two baffles, a plurality of wire outlet grooves are formed in one baffle, and L-shaped terminals and I-shaped thermals are all arranged on the baffle provided with wire outlet grooves. The edges of the two ends of the secondary wire rack are respectively provided a circular baffle, a space where coils are wound is formed between the two baffles, a plurality of wire outlet grooves are formed in one baffle, and L-shaped terminals and I-shaped thermals are all arranged on the baffle provided with wire outlet grooves. The primary wire rack is sleeved with the secondary wire rack, and the baffle, without wire outlet grooves, of the primary wire rack abuts against the outer end of the baffle, with the wire outlet groove, of the secondary wire rack. Due to the facts that the improved structure of the transformer wire rack is composed of the primary wire rack and the secondary wire rack, and the primary wire rack and the secondary wire rack (framework) are independent, the primary wire rack and the secondary wire rack can be machined (produced) respectively, and production efficiency is high.

1, the coiling volume is little;
2, primary and secondary winding wiring (lead-in wire) complex procedures;
3, be unfavorable for doing ground protection (adding copper sheet or Copper Foil) between first coil;
4, Thermal Cutoffs, current insurance silk are installed inconvenient;
5, because the primary and secondary coil is divided into left and right two grooves, coupling is poor, and efficiency is lower.
The utility model content
The purpose of this utility model is to provide a kind of improvement structure of easy to process, production efficiency is high, coupling is good transformer coil holder.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of improvement structure of transformer coil holder, and it is comprised of elementary coil holder and secondary coil holder; The two ends edge of described elementary coil holder has respectively one around all-round baffle plate, forms the space of winding around between two baffle plates, offers a plurality of line outlet grooves on a baffle plate, and L-type terminal and I type terminal all are arranged on the baffle plate with line outlet groove; The two ends edge of described secondary coil holder has respectively one around all-round baffle plate, forms the space of winding around between two baffle plates, offers a plurality of line outlet grooves on a baffle plate, and L-type terminal and I type terminal all are arranged on the baffle plate with line outlet groove; Described elementary coil holder is nested with in secondary coil holder and elementary coil holder leans without the baffle plate of line outlet groove the baffle plate outer end that has line outlet groove at secondary coil holder.The line outlet groove of described elementary coil holder is 2-10; The line outlet groove of secondary coil holder is 2-10.
After adopting such scheme, the utlity model has following advantage:
1, the utility model is comprised of elementary coil holder and secondary coil holder, and elementary coil holder and secondary coil holder (skeleton) are for independently individual, but separate machined (production), and production efficiency is high.
2, elementary coil holder, secondary wire inside elementary line holds hold the secondary coil holder of outside, and are all single groove structure, be coupled, and single groove structure copper cash tiling area are larger, is conducive to the heat radiation of line bag.
3, elementary coil holder and secondary coil holder are assembled by the mode of socket, and be easy to assembly, quick, easy to process.
4, elementary coil holder and secondary coil holder are isolated fully, and coefficient of safety improves.
5, elementary coil holder and secondary coil holder, all with L-type terminal, I type pin pin (hardware), are convenient to routing (bonding wire) and current insurance silk, Thermal Cutoffs installation.
6, elementary coil holder and secondary coil holder are convenient to do ground protection (adding copper sheet or Copper Foil).
7, the coiling volume is larger, and cost is lower.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.

Embodiment
As shown in Figure 3, Figure 4, be first embodiment of the improvement structure of a kind of transformer coil holder of the utility model, it is comprised of elementary coil holder 1 and secondary coil holder 2.
The two ends edge of described elementary coil holder 1 has respectively one around all- round baffle plate 11,12, form the space of winding around between two baffle plates 11,12, offer a plurality of line outlet grooves 111 on a baffle plate 11, L-type terminal 13 and I type terminal 14 all are arranged on the baffle plate 11 with line outlet groove 111.
The two ends edge of described secondary coil holder 2 has respectively one around all- round baffle plate 21,22, form the space of winding around between two baffle plates 21,22, offer a plurality of line outlet grooves 211 on a baffle plate 21, L-type terminal 23 and I type terminal 24 all are arranged on the baffle plate 21 with line outlet groove 211.
Described elementary coil holder 1 is nested with in secondary coil holder 2 and elementary coil holder 1 leans without the baffle plate 12 of line outlet groove baffle plate 21 outer ends that have line outlet groove 211 at secondary coil holder 2.L-type terminal 13 on elementary coil holder 1, I type terminal 14 are identical with L-type terminal 23, I type terminal 24 directions on secondary coil holder 2.
