Abstract

The utility model relates to a combined coil former which consists of a wrapping post, an upper baffle and a lower baffle; the upper baffle, the lower baffle and the wrapping post are provided with inner holes used to contain magnetic cores; the coil former is characterized in that both ends of the wrapping post are provided with separation blades; the shape and the size of the inner holes of the wrapping post are matched with that of the inner holes of the upper and the lower baffles, and the inner holes of the wrapping post are inlaid between the upper baffle and the lower baffle. Also, the wrapping post, the upper baffle and the lower baffle can serve as components, the shape and the size of the inner holes are the same, and the upper baffle and the lower baffle are spliced on both ends of the wrapping post. The inner holes of the wrapping post, the upper baffle and the lower baffle are respectively rectangular, circular, semi-circular, oval, trapezoidal, triangular and the like. Because the utility model is a combined coil rack, the wrapping post is singly processed, and the wall thickness is not restricted by the machine injection and processing requirements, the coil rack can easily process quite thin products with thickness less than 0.1mm, thereby reducing the length and the materials of a coil enameled wire, saving copper and prolonging the service life of the product.

Description

A kind of combined-type coil frame

One, technical field

The utility model relates to a kind of bobbin, relates in particular to a kind of combined-type coil frame.

Two, background technology

Traditional bobbin is an integrative-structure, four faces that the endoporus of wrapping post contacts with the magnetic core center pillar in the middle of the bobbin are the structure of full bag, because the machine injection moulding is processed with thickness requirement, its thickness requirement limiting proportion is thicker, general requirement will be more than 0.7mm, in order to satisfy the thickness requirement of machine injection moulding processing, and be convenient to the accessory combine and assemble, the cooperation place of its endoporus and magnetic core, must leave certain clearance, the wall ratio that adds wrapping post is thicker, the girth that causes winding the line will increase, and has increased the length and the material of coil varnish envelope curve, and device self copper resistance is increased, copper loss is also along with increase, the temperature of device also can raise, and waste material is also wasted electric energy, reduces the useful life of product.

Three, summary of the invention

The technical problem that the utility model solves is the thickness that reduces the wrapping post wall thickness, thereby reduces the length and the material of coil varnish envelope curve, reaches the purpose of saving copper material, can prolong the bobbin in product useful life.

For solving the problems of the technologies described above, the utility model is achieved in that

It is made of wrapping post, overhead gage and lower baffle plate, overhead gage, lower baffle plate and wrapping post are provided with the endoporus of dress magnetic core, described wrapping post two ends are provided with catch, and hole shape and size are complementary with upper and lower baffle plate endoporus in the wrapping post, and are embedded between the upper and lower baffle plate.

Wherein said wrapping post, overhead gage and lower baffle plate are assembly, and hole shape is identical with size in it, and overhead gage and lower baffle plate are bonded in the wrapping post two ends.

The shape of wherein said wrapping post endoporus and upper and lower baffle plate endoporus is respectively structures such as rectangle, circle, semicircle, ellipse, trapezoidal, triangle.

Because the utility model is the combined-type coil frame, wrapping post is processed separately, the thickness of its wall thickness is not limit by the requirement of machine injection moulding processing, can process easily thickness below 0.1mm than thin product, thereby reduce the length and the material of coil varnish envelope curve, reach the saving copper material, prolong the product purpose in useful life.

Four, description of drawings

Concrete structure of the present utility model is provided by the following drawings.

Fig. 1 is according to the combined-type coil shelf structure schematic diagram that the utility model proposes.

Fig. 2 is according to another exemplary construction schematic diagram of combined-type coil frame that the utility model proposes.

Sign in the accompanying drawing is represented respectively: 1. 6. wrapping post endoporus, 7. catch in stitch 2. lower baffle plates 3. wrapping posts 4. overhead gages 5. baffle plates

Five, embodiment

As can be seen from Figure 1, the utility model is made of wrapping post 3, overhead gage 4 and lower baffle plate 2, overhead gage 4, lower baffle plate 2 and wrapping post 3 are provided with the

rectangle endoporus

5,6 of dress magnetic core, wrapping post 3 two ends are provided with catch 7, wrapping post endoporus 6 sizes are complementary with upper and lower baffle plate endoporus 5, and are embedded between the upper and lower baffle plate 4,2.During manufacturing, wrapping post 3 adopts sheets to become the structure of rectangle again, and what requirement its machine when production and processing does not have substantially for wall thickness minimum production thickness, just can do thinlyyer very easily, for example 0.025mm etc.Stitch 1 is not essential as required.Wrapping post 3 is embedded between the upper and

lower baffle plate

4,2 gets final product.As can be seen from Figure 2, the utility model can be wrapping post 3, overhead gage 4 and lower baffle plate 2 assembly also, and its

endoporus

6,5 is rectangle, and size is identical, and overhead gage 4 and lower baffle plate 2 are bonded in wrapping post 3 two ends.During manufacturing, wrapping post 3, overhead gage 4 and lower baffle plate 2 are processed respectively, and stitch 1 is not essential as required, overhead gage 4 and lower baffle plate 2 are bonded in wrapping post 3 two ends get final product.Shapes such as that wrapping post endoporus 6 and upper and lower baffle plate endoporus 5 also can be done is circular, semicircle, oval, trapezoidal, triangle.
