Abstract
The utility model relates to a surface pasting magnetic bead, which is pasted on a printed circuit board and comprises a body and connecting pins, wherein the body is made of iron powder and is in surface contact with the printed circuit board, and the connecting pins are covered in the body, extend out from two opposite sides of the body and form linear contact with the printed circuit board after being bent. The surface pasting magnetic bead adopts the surface pasting making process, so the surface pasting magnetic bead has the characteristic of low height and meets the requirements of thin appearance of electronic products.
Description
Technical field
The present invention relates to filter element, particularly a kind of magnetic bead.
Background technology
Filter element and anti-electromagnetic interference element are the primary element of electronic product.Magnetic bead is filter element and an anti-electromagnetic interference element more and more commonly used.Usually the dual inline type magnetic bead that adopts adopts standing position to insert on the printed circuit board (PCB), and is highly higher, can't satisfy the slimming trend of following electronic product.
Summary of the invention
In view of this, need provide a kind of surface mount magnetic bead, have than low height.
A kind of surface mount magnetic bead is mounted on the printed circuit board (PCB), comprises body and pin.Body is made by iron powder, and described body contacts with described printed circuit board (PCB) face.Pin is coated in the described body, and is stretched out by the relative both sides of described body, forms line with described printed circuit board (PCB) and contact after bending.
Preferably, described body is any in square body, triangle body, rhombogen, prismatoid and the polyhedral body.
A kind of surface mount magnetic bead is mounted on the printed circuit board (PCB), comprises body and pin.Body is made by iron powder, and described body contacts with described printed circuit board.Pin is coated in the described body, and is stretched out by the relative both sides of described body, contacts with described printed circuit board (PCB) formation face after bending.
Preferably, described body is a cylinder.
Preferably, described pin comprises extension, first fixed part, second fixed part and connecting portion.Extension is coated in the described body, and is stretched out by the relative both sides of described body.First fixed part is mounted on the described printed circuit board (PCB).Second fixed part is mounted on the described printed circuit board (PCB), links to each other with described first fixed part and forms angle.Connecting portion connects described extension and described first fixed part.
Preferably, described first fixed part is opposite at the bearing of trend of the relative both sides of described body with the angle that described second fixed part forms.
Above-mentioned surface mount magnetic bead adopts the surface mount processing procedure, thereby has the feature of low clearance, satisfies the requirement of electronic product slimming.In addition, the surface mount magnetic bead adopts body or pin to contact with the printed circuit board (PCB) face, thus firm surface mount magnetic bead, in order to the surface mount processing procedure.

Embodiment
Fig. 1 is the schematic diagram of surface mount magnetic bead 10 in the utility model first execution mode.In the present embodiment, surface mount magnetic bead 10 adopts the surface mount processing procedure to be mounted on the printed circuit board (PCB) 20, and links to each other with other electron component 30 via Copper Foil 40.Surface mount magnetic bead 10 comprises body 100 and pin 110.Body 100 is made by iron powder, has the advantage of high anti-electric current, can be applicable on the electronic product of high wattage.Body 100 contacts with printed circuit board (PCB) 20 formation faces, and it comprises lower surface 101, and is smooth on printed circuit board (PCB) 20.Body 100 relies on lower surface 101 to contact with printed circuit board (PCB) 20 formation faces, thereby can be fixed on printed circuit board (PCB) 20, in order to the surface mount processing procedure.
In the present embodiment, body 100 is a square body.In second execution mode of utility model, as shown in Figure 2, body 100A is a triangle body, and itself of surface mount magnetic bead 10A and structure are identical with the surface mount magnetic bead 10 among Fig. 1, thereby, no longer describe in detail herein.In other execution mode of the present utility model, body 100A also can be any in the cube that rhombogen, prismatoid and polyhedral body etc. have the plane.
Figure 3 shows that the schematic diagram of surface mount magnetic bead 10B in the utility model the 3rd execution mode.In the present embodiment, surface mount magnetic bead 10B is mounted on the printed circuit board (PCB) 20, and is connected with other electron component 30 via Copper Foil 40.Surface mount magnetic bead 10B comprises body 100B and pin 110B.Body 100B is made by iron powder, and contacts with printed circuit board (PCB) 20 formation lines.In the present embodiment, body 100B is a cylinder.
Surface mount magnetic bead 10 of the present utility model, 10A, 10B adopt the surface mount processing procedure, thereby have the advantage of low clearance, satisfy the requirement of electronic product slimming.In addition, surface mount magnetic bead 10,10A, 10B adopt body or pin to contact with 20 of printed circuit board (PCB)s, thus firmly surface mount magnetic bead 10,10A, 10B, in order to the surface mount processing procedure.
