Shell 20 can also select other metal good conductor materials, such as using aluminium, steel, iron, copper at.
In order to improve effectiveness, the second metallic shield 50, second metal are provided on the mainboard 10
Shielding case 50 and first metallic shield 30 are separately positioned on 10 two sides of mainboard.By deviating from institute in the mainboard 10
It states 30 side of the first metallic shield and the second metallic shield 50 is set, play the effect being electromagnetically shielded to the side of mainboard 10
Fruit.
The utility model on the end face that the first metallic shield 30 is connected with shell 20 it is alternatively possible to be arranged open
Structure, that is, the plane is removed, to form entire hatch frame, the metal edge and shell of the first metallic shield 30 at this time
20 are connected；Multiple hatch frames can be set in the plane that the first metallic shield 30 is connected with shell 20, make the table
Face forms porous structure；For the first metallic shield 30 in a plane of shell 20, it can be also provided with opening, it is corresponding
The size and shape of opening can be determined according to shielding needs, processing cost and difficulty of processing.
Referring to Fig. 2, the following are the first embodiment that the utility model is applied to the electromagnetic armouring structure of ultrasonic device, In
In the present embodiment, conducting foam is filled between 30 edge of the first metallic shield and the contact surface of the mainboard 10
40。
Since conducting foam 40 is to wrap up conductive fabric on flame-retardant sponge, after a series of processing, make it have good
Good surface conductivity.The first metallic shield 30 is filled by using conducting foam 40 to be in contact with mainboard 10 seam at position
Gap can play the effect for preventing electromagnetic interference from revealing；Simultaneously as conducting foam 40 is conductive, mainboard can be increased
10 ground connection reduce influence of the electromagnetic interference of the generation of mainboard 10 to external equipment.
Referring to Fig. 3, the following are the second embodiment that the utility model is applied to the electromagnetic armouring structure of ultrasonic device, this
The difference of embodiment and first embodiment is, in the present embodiment, at 30 edge of the first metallic shield and the shell
Conducting foam 40 is filled between the contact surface of body 20, the technology effect in the technical effect and first embodiment of the conducting foam 40
Fruit is identical, repeats no more.
Conducting foam, technical effect can be filled between 50 edge of the second metallic shield and the contact surface of mainboard 10
It is identical as the technical effect in first embodiment, it repeats no more.
Please continue to refer to Fig. 1, Fig. 2 and Fig. 3, the following are the utility model to be applied to the electromagnetic armouring structure of ultrasonic device
3rd embodiment in the present embodiment, discloses the preferred structure of first metallic shield 30, it is preferable that the opening is set
In the plane that first metallic shield 30 is connected with the shell 20, make first metallic shield 30 with it is described
The side plane that shell 20 is connected is in uncovered structure, and the metallic shield 30 is equipped with away from a side plane of the shell 20
Opening forms it into the frame structure of uncovered structure or hollow out.
When the electromagnetic wave that mainboard 10 generates reaches shell by the engraved structure or hatch frame of the first metallic shield 30
When 20, under the action of shell 20, electromagnetic wave leakage can be avoided, simultaneously as the surface of the first metallic shield 30 is open,
The surface does not need processing closing, makes its weight is opposite to reduce, while 20 structure of shell being cooperated to avoid electromagnetic wave leakage, Neng Gouyou
Help reduce the volume of the first metallic shield 30.
