Abstract

The utility model discloses an annular coil framework relating to electric appliance parts, in particular to a framework for winding a coil. The annular coil framework consists of a coil frame and a base, wherein the middle positions at the two opposite sides of the base are respectively provided with a central edge, two sides of which are respectively provided with a side edge; two clamp grooves are formed between the two side edges and one central edge; two splicing raised edges that are axially and parallelly arranged are arranged at the side parts of the annular coil frame, and two ends of the two splicing raised edges are respectively inserted between the two side edges and the centre edge of the base; and the inner side of the centre edge is protruded to form a buckle, and the lower part of a central line of the coil frame is provided with a clamp platform that is clamped with the buckle. The clamp grooves play a positioning role, and the buckle of the centre edge plays a fixing role. The annular coil framework solves the problems that the base of the coil framework in the prior art is adhered with a copper wire by glue and that the base of the framework is easy to deform due to heating. The annular coil framework can effectively reduce the product cost, and improve the product durability and production efficiency.

Description

The loop coil skeleton

Technical field

The utility model relates to electric component, particularly a kind of skeleton of winding around.

Background technology

The coil rack of traditional design generally is to adopt in the side of base to insert mounting means, clings with adhesive again, and there is following shortcoming in coil like this: one, energising afterwards coil be heated, can make adhesive lose adhesiveness, separate easily between skeleton and the base; Two, be under pressure or temperature when higher skeleton base easy deformation when coil part; Three, coil rack can not separate with the skeleton base, and is very inconvenient during operation, influences production efficiency.

The utility model content

The purpose of this utility model provides a kind of loop coil skeleton, the utility model has improved the problem that skeleton base that the coil rack of prior art exists and copper cash cause with the glue adhesive surface, solved the skeleton base easy deformation of being heated, very inconvenient during operation, influence problems such as production efficiency.The utility model reduces product cost, has improved production efficiency.

Loop coil skeleton of the present utility model is made up of bobbin and base, in the centre position of two relative sides of base a center rib is arranged respectively, on each rib both sides, center an incline is arranged respectively, forms two clip slots between two inclines and a center rib; There are two grafting fins that be arranged in parallel vertically in limit portion at the described bobbin of annular, and insert respectively between two inclines and center rib of base at the two ends of two grafting fins.

Loop coil skeleton of the present utility model has the following advantages: one, coil rack separates with base, and the coil rack coiling is not easy to make mistakes easily; By combination, lock out operation, can increase work efficiency; Two, base has check design, when element is under pressure or temperature when higher, is not easy distortion; Three, the coil copper cash can adopt direct insertion design, saves cost, beautifies outward appearance; And, reduce product cost without adhesive, improved production efficiency.

Embodiment

Below in conjunction with accompanying drawing and with illustrated embodiments the utility model is done detailed explanation.

Embodiment one

Consult Fig. 1-3, the loop coil skeleton is made up of bobbin 1 and base 2, in the centre position of two relative sides of base 2 a center rib 2-2 is arranged respectively, on each rib 2-2 both sides, center an incline 2-1 is arranged respectively, form two clip slots between two incline 2-1 and a center rib 2-2; There are two grafting fin 1-1 that be arranged in parallel vertically in limit portion at the described bobbin 1 of annular, and insert respectively between two the incline 2-1 and center rib 2-2 of base 2 at the two ends of two grafting fin 1-1.The cross sectional shape of described two grafting fin 1-1 is in the shape of the letter V.The striped 2-3 that the criss-cross projection is arranged on the bottom surface of described base 2.Coil patchhole 2-4 is arranged on base 2.Described bobbin 1 vertical diametrical position has dividing plate 3, and dividing plate 3 plays the effect of safe insulation.

Above-mentioned coil skeleton structure has coil patchhole 2-4 on base 2, the copper cash of coil can adopt the formula of inserting design, can save the set-up time, has shortened production process greatly, provides cost savings and has beautified outward appearance.The coil of plug-in type is heated and also is not easy distortion.Coil rack separates with base, and the coil rack coiling is difficult for makeing mistakes easily, plugs base again after coiling is finished, and is convenient and swift, improved operating efficiency.The striped 2-3 that the criss-cross projection is arranged on base when element is under pressure or temperature when higher, is not easy distortion.

Embodiment two

Consult Fig. 2, present embodiment is with embodiment one difference: in base 2 relative dual-side portions one row's line hole 2-5 is arranged, the line hole on each limit is positioned at the minimum of middle part, increase gradually from the centre to both sides line hole size, the edge port 2-6 of each line hole 2-5 is that boss 2-7, inner end are arranged is circular port 2-8 square, both sides, middle part, and the edge port 2-6 width of above-mentioned line hole 2-5 is less than circular port 2-8 diameter.The line hole of said structure is multilevel hierarchy, and copper cash is bigger than inlet, and the first order plays the screens effect, and second level chucking enters circular port copper cash is blocked, and has played effectively firmly effect.
