Abstract
The utility model relates to a fixed sheet of an EMI shade. The fixed sheet at least includes a base body and clamps. The base body is provided with at least one plane part, and the two sides of the plane part are provided with extending parts which extends linearly. The clamps are arranged on the extending parts. The clamp is provided with springs which extend upward from the two sides of the extending part. A protruding part which protrudes inward is arranged near the top of the spring. A side plate of the EMI shade can insert into the clamps, and the side plate of the EMI shade is provided in parallel with at least one outstanding part, so the protruding parts of the clamp can be snapped above the outstanding parts to reach an fixing effect, and the outstanding parts can be simply separated from the protruding parts by being pulled out upward, and consequently the maintenance becomes convenient.
Description
Technical field
The utility model relates to a kind of stator of EMI shade, especially refers to fast this EMI shade to be carried out the stator of the EMI shade of dismounting operation.
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 inner member 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 particular electronic component 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 component of required shielding, and support arm is fixed on the circuit board that this electronic component is set through modes such as welding.Yet in actual production or maintenance process, when electronic component went wrong, the engineering staff needed earlier electro-magnetic shielding cover to be separated postwelding and pulls down, and just can check electronic component then.Above-mentioned electro-magnetic shielding cover makes the engineering staff inconvenient when operating maintenance.
The utility model content
The technical problem that the utility model solved can be carried out this EMI shade the stator of the EMI shade 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 includes: a pedestal, and this pedestal is provided with at least one planar portions, and this planar portions both sides straight-line extension has extension; And anchor clamps, to be located on each extension, these anchor clamps are provided with the shell fragment that is uprightly extended by these extension both sides up, and each shell fragment is near the top and be formed with protuberance inwardly.
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 protuberance clip of these anchor clamps to be fixed in this protuberance top.
This planar portions is provided with at least one breach.
This extension is provided with at least one breach.
This planar portions and extension are provided with at least one breach.
This protuberance top forms extratensive type
The beneficial effect of the utility model is: a pedestal and anchor clamps; This pedestal is provided with at least one planar portions; This planar portions both sides straight-line extension has extension, and these anchor clamps are provided with the shell fragment that is uprightly extended by these extension both sides up, and each shell fragment is near the top and be formed with protuberance inwardly; 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 protuberance clip of these anchor clamps to be fixed in this protuberance top and reach fixed effect, maybe can upwards extract and reaches 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, and these anchor clamps 12 are provided with the shell fragment 121 that is uprightly extended by this extension 112 both sides up, and each shell fragment 121 is near the top and be formed with protuberance 122 inwardly, and these protuberance 122 tops form the outer form of opening.
During whole the use; As shown in Figure 3, this stator 1 can be fixed in earlier on the circuit board 2, and 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 also is provided with at least one protuberance 311, by this, please consults shown in Figure 4 simultaneously; Has a suitable elastic space with two shell fragments 121; Protuberance 122 then receives the elastic reaction of shell fragment 121 and has the function of the side plate 31 of this EMI shade 3 of clamping, and top 122 of protuberances forming extratensive type have guiding side plate 31 and strut protuberance 122 according to this and get into shell fragments 121, but protuberance 311 clips of each side plate are fixed in these protuberance 122 belows and reach fixed effect.
In addition, 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.
