Description
Technical field
A kind of core structure for three-dimensional structure radio-frequency coil of the utility model is related to the application coil of induction system, especially
It is the radio-frequency coil of three-dimensional structure.
Background technology
Conventional coil is typically all simple one-dimensional coil, and magnetic flux is stronger in central axis direction, and magnetic flux is close in space
Spend uneven, coil generally will can just be worked normally in specific direction or position, and flexibility is relatively low.The radio frequency line of three-dimensional structure
Circle, generally comprises the absolute coil in three directions of XYZ axis in an iron core and space coordinate, and three single shaft coils pass through from three
Different directions is one by one directly around to being grouped together on iron core, then be positioned on pcb board.The radio frequency line of such three-dimensional structure
Circle can produce stronger magnetic flux in all directions, coupled resonance can occur with coil in different directions, therefore using
When can be more flexible with unlimited position and direction, use.
But the radio-frequency coil of above-mentioned three-dimensional structure is needed along the three direction difference coilings of XYZ axis once in coiling, such as
Shown in Fig. 1, magnetic core 51 is clamped with fixture, the coiling 52 on magnetic core 51, fix the lead of 52 coils, it is ensured that without interference with
The coiling of 53 coils, then clamping magnetic core coiling 53 again, finally in installing coil 54, so needs to unload to press from both sides again again
Fill magnetic core, again and again, and due to the small volume of radio-frequency coil itself, coiling work consuming of getting up is time-consuming, work efficiency compared with
Low, the inferior rate of product is higher.
Utility model content
A kind of purpose of core structure for three-dimensional structure radio-frequency coil of the utility model is exactly to overcome above-mentioned existing skill
The defects of art, by varying the structure of magnetic core, be attached on magnetic core using directly being covered around the air core coil made according to specification in advance
The making of coil has been completed, has reached time saving and energy saving, has improved efficiency, has improved the purpose of product fine rate.
A kind of core structure for three-dimensional structure radio-frequency coil of technical solutions of the utility model, including magnetic core (or iron core)
Body 1, it is characterised in that the core body 1 is all rectangle or square straight quadrangular for upper and lower bottom surface；In the magnetic core
The side 1 of body 1 is equipped with convex block 1, and convex block 2 120 is equipped with the side 2 12 adjacent with the side 1.
A kind of above-mentioned core structure for three-dimensional structure radio-frequency coil, the convex block 1 are located at the side one
On 11 one cambered surface 1111 of convex block is extended to form along the first incline 13；The convex block 2 120 is located on the side 2 12 along second
Incline 14 extends to form two cambered surface 1201 of convex block.
A kind of above-mentioned core structure for three-dimensional structure radio-frequency coil, first incline 13 are with the second incline 14
Diagonal distribution.
Using upper structured core or iron core, it can utilize and be attached to magnetic around the air core coil made directly set according to specification in advance
The making of coil has been completed on core, has reached time saving and energy saving, has improved efficiency, has improved the purpose of product fine rate.

Embodiment
The utility model is further described with reference to embodiment and attached drawing.
It is a kind of core structure embodiment for three-dimensional structure radio-frequency coil of the utility model as shown in Figure 2 and Figure 3.Bag
Magnetic core (or iron core) body 1 is included, which is all square straight quadrangular for upper bottom surface 16 and bottom surface 18；At this
The side 1 of core body 1 is equipped with convex block 1, and convex block two is equipped with the side 2 12 adjacent with the side 1
120.The convex block 1 is located on the side 1 and extends to form convex block into the side 1 along the first incline 13
One cambered surface 1101；The convex block 2 120 is located on the side 2 12 and extends simultaneously along the second incline 14 to the side 2 12
Form two cambered surface 1201 of convex block.First incline, 13 and second incline 14 is two ribs being diagonally distributed.
It is illustrated in figure 4 the schematic diagram that the embodiment magnetic core makes coil.
Step 1：It will be attached in advance according to specification around the air core coil A made directly sets on magnetic core 1, at this time shown convex block
2 120 are used to fix hollow coil A as baffle；
Step 2：Then will be attached to again also according to specification around the hollow coil B made directly sets on magnetic core 1, at this time institute
Show that convex block 1 is used to fix hollow coil B as baffle；
Step 3：The magnetic core for assembling air core coil A and air core coil B is assembled on pcb board, then again by tubular wire
Circle C is sleeved on magnetic core periphery, two cambered surface 1201 of one cambered surface 1101 of convex block and convex block is fastened, then again in pcb board respective foot position
Assembled into line lead scolding tin.
Such structure and step, which make three-dimensional structure radio-frequency coil, can effectively improve efficiency, improve product yield, lifting
Product fine rate.
It these are only the preferred embodiment of the utility model, be not intended to limit the present invention, for this area
