Abstract
The utility model discloses a clamping sheet of an EMI (Electromagnetic Interference) mask, which at least comprises a seat body and clamps. The seat body is provided with at least one plane part; extending parts linearly extend on two sides of the plane part; the clamps are arranged on the extending parts; the clamps are provided with elastic sheets which extend upwards from two sides of the extending parts; the elastic sheets are relatively positioned below, form vertical parts, and are upwards expanded into outwards-expanded parts; further, two elastic sheets are opposite to the vertical parts and are provided with through holes; the outwards-expanded parts are provided with pressing parts which downwards extend towards the insides of the clamps; a side plate of the EMI mask can be inserted into the clamps; the side plate of the EMI mask is provided with convex parts side by side, and can be clamped below the pressing parts to achieve a fixing effect or can be upwards pulled out to achieve the purposes of simple separation operation and repair.
Description
Technical field
The utility model relates to a kind of EMI shade intermediate plate, especially refers to fast this EMI shade to be carried out the EMI shade intermediate plate 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 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 is promptly providing an EMI shade intermediate plate, can fast this EMI shade be carried out the dismounting operation.
The technical scheme of the utility model is: a kind of EMI shade intermediate plate 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; 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 upright portion, more upwards then for expanding as the outer portion of opening; And two shell fragments are with respect to this upright portion place and be provided with a perforation, and each outer portion of opening is extended with clamping part downwards towards anchor clamps inside.
Wherein, this EMI shade is provided with plural side plate and fixes for this intermediate plate, and each side plate and be provided with at least one protuberance, supplies 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 upright portion, more upwards then for expanding as the outer portion of opening; And two shell fragments are with respect to this upright portion place and be provided with a perforation; Each outer portion of opening is extended with clamping part downwards towards anchor clamps inside, 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; But clip reaches fixed effect in this clamping part below, maybe can upwards extract and reaches the purpose of the operation and the maintenance of simple separation.

Embodiment
The utility model EMI shade intermediate plate basic structure such as Fig. 1 and shown in Figure 2, this intermediate plate 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 upright portion 122, is straight upwardly extending plate for opening 123, two upright portions 122 of portion outside expanding as then upwards again; And two shell fragments 121 are with respect to these upright portion 122 places and be provided with a perforation 124, and each outer portion 123 of opening is extended with clamping part 125 downwards towards anchor clamps inside.
During whole the use, as shown in Figure 3, this intermediate plate 1 can be fixed in earlier on the circuit board 2; It is fixing that other has an EMI shade 3 to be assembled by this intermediate plate 1 top down, and it is fixing for this intermediate plate 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 4ly simultaneously,, have a suitable elastic space with two shell fragments, 121 formed upright portions 122; Open portion 123 outward and then have guiding side plate 31 and strut clamping part 125 according to this and get into upright portion 122 belows, but make protuberance 311 clips of each side plate be fixed in these clamping part 125 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.
