Description
Technical field
The utility model especially refers to fast this EMI shade to be carried out the EMI shade stator of dismounting operation relevant for a kind of stator of EMI shade.
Background technology
As is generally known; Nearly all electronic product all can produce electromagnetic interference (Electromagnetic Interference in operation; EMI) problem, and after electromagnetic interference promptly is meant electric product itself energising, because of electromagnetic wave that electromagnetic induction effect produced to arround interference effect that electronic equipment caused; Also because electromagnetic interference can cause other electric equipment work interruption, undesired shutdown, safeguards increase, crosstalk and system delay; And cause injury of human body etc., therefore, advanced country all makes laws for the electromagnetic problem of electronic product and gives standard.
Be with; Product just must be to possible electromagnetic problem in planning and designing; Get rid of,, and arranges from external device (ED)s such as shell, slot, apertures to intraware and material etc. is done accurate the design to entire product if do not consider in that design initial is scrupulous; Can't be when the later stage through when test, spent cost will be much larger than estimating originally.For in response to aforesaid requirement, the specific electronic components of some on circuit board all can cover the EMI shade in addition more at present, to avoid the separated evil of electromagnetic wave radiation effect.
The support arm that the cover body that the EMI shade that industry adopts usually is formed in one, this cover body have roof and go out from roof periphery vertical extent.During use, this cover body is covered on the electronic building brick of required shielding, and support arm is fixed on the circuit board that this electronic building brick is set through modes such as welding.Yet in actual production or maintenance process, when electronic building brick went wrong, the engineering staff needed earlier electro-magnetic shielding cover to be separated postwelding and pulls down, and just can check electronic building brick then.Above-mentioned electro-magnetic shielding cover makes the engineering staff inconvenient when operating maintenance.
The utility model content
In view of this, the technical problem that the utility model solved can be carried out this EMI shade the EMI shade stator of dismounting operation fast promptly at the stator that a kind of EMI shade is provided.
The technical scheme of the utility model is: a kind of stator of EMI shade, and it includes: a pedestal, this pedestal is provided with at least one planar portions, and this planar portions both sides straight-line extension has extension; And anchor clamps; Be located on each extension; These anchor clamps are provided with the shell fragment that is extended by these extension both sides up, and this shell fragment is positioned at the below relatively and forms the belly than large space, is extended down to the neck that the top is punctured into small distance; Again upwards then for expanding as an outer portion, and two shell fragments are with respect to this belly place and be provided with a perforation.
Wherein: this outer portion's end is an arc portion towards inner bending further.
Wherein: this EMI shade is provided with plural side plate and fixes for this stator, and each side plate and be provided with at least one protuberance, can supply the perforation clip of these anchor clamps to fix.
Wherein: this planar portions is provided with at least one breach.
Wherein: this extension is provided with at least one breach.
Wherein: this planar portions and extension are provided with at least one breach.
The beneficial effect of the utility model is: a pedestal and anchor clamps, and this pedestal is provided with at least one planar portions, and this planar portions both sides straight-line extension has extension; These anchor clamps are located on each extension; It is provided with the shell fragment that is extended by these extension both sides up, and this shell fragment is positioned at the below relatively and forms the belly than large space, is extended down to the neck that the top is punctured into small distance; Again upwards then for expanding as the outer portion of opening; And two shell fragments are with respect to this belly place and be provided with a perforation, and the side plate of this EMI shade can insert these anchor clamps, and the side plate of this EMI shade and be provided with at least one protuberance; Can supply the perforation clip of these anchor clamps to reach fixed effect, maybe can upwards extract and reach the purpose of the operation and the maintenance of simple separation.

Embodiment
The stator basic structure of the utility model EMI shade such as Fig. 1 and shown in Figure 2, this stator 1 includes at least: a pedestal 11 and anchor clamps 12; Wherein:
This pedestal 11 is provided with at least one planar portions 111, and these planar portions 111 both sides straight-line extensions have extension 112.
These anchor clamps 12 are located on each extension 112; These anchor clamps 12 are provided with the shell fragment 121 that is extended by this extension 112 both sides up; This shell fragment 121 is positioned at the below relatively and forms the belly 122 than large space; Be extended down to the top and be punctured into the neck 123 of small distance, upwards then open portion 124 outward again, and two shell fragments 121 are with respect to these belly 122 places and be provided with one and bore a hole 125 for expanding as.
During whole the use, as shown in Figure 3, this stator 1 can be fixed in earlier on the circuit board 2; Other has an EMI shade 3 to assemble fixing down by this stator 1 top; It is fixing for this stator 1 that this EMI shade 3 is provided with plural side plate 31, and each side plate 31 and be provided with at least one protuberance 311, by this; Please consult shown in Figure 4 simultaneously; With two shell fragments, 121 formed bellies 122, have a suitable elastic space, neck 123 then receives the elastic reaction of belly 122 and has the function of the side plate 31 of this EMI shade 3 of clamping; Open portion 124 outward and then have guiding side plate 31 and strut neck 123 according to this and get into bellies 122, reach fixed effect in this perforation 125 but protuberance 311 clips of each side plate are fixed in.
In addition, shown in second embodiment of Fig. 5, outer portion's 124 ends of this stator are arc portion 126 towards inner bending further, can avoid this outer portion 124 to cause the danger of scratch; And this planar portions 111 and/or extension 112 are provided with at least one breach 113, and be as shown in Figure 1, and when making fixed structure be welded in circuit board, this breach 113 can increase the contact area with scolder, can strengthen its solid welding effect.
