Abstract

The utility model provides an EMI (Electromagnetic Interference) mask fixing structure, which at least comprises a base body and clamps, the base body at least is provided with a plane part, and the two sides of the plane part extend in a straight line to form extending parts; the clamps are arranged on the extending parts, spring leaves extending upwards from the two sides of the extending parts are arranged on the clamps, and the spring leaves comparatively form abdomen parts with larger space at the lower parts, extend upwards to form neck parts with a small diameter, further expand upwards to form outwardly expanded parts, thus side plates of the EMI mask are fixedly clamped in an inserting manner or are pulled out upwards to achieve the purpose of simple detachment for maintenance.

Description

EMI shade fixed structure

Technical field

The utility model especially refers to fast this EMI shade to be carried out the EMI shade fixed structure of dismounting operation relevant for a kind of EMI shade fixed structure.

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 at possible electromagnetic problem in planning and designing, got rid of, if not in the scrupulous consideration of design initial, and arrange from external device (ED)s such as shell, slot, apertures to intraware and material etc. is done accurate design at entire product, can't be when the later stage by 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 shade, 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 electromagnetism shade cover to be separated postwelding and pulls down, and just can check electronic building brick then.Above-mentioned electromagnetism shade cover makes engineering staff's inconvenience when operating maintenance.

The utility model content

The technical problem that the utility model solved is to provide a kind of EMI shade fixed structure, can fast this EMI shade be carried out the EMI shade fixed structure of dismounting operation.

The technical solution of the utility model is: a kind of EMI shade fixed structure, and it includes at least: 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, to 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 belly of below formation than large space relatively, is extended down to the neck that the top is punctured into small distance, more upwards then for expanding as the outer portion of opening.

Wherein, further be formed with the segment difference section between this planar portions and this extension, make the height of this extension be higher than this planar portions.

This extension is terminal and be formed with afterbody, further is formed with the segment difference section between this afterbody and this extension, makes the height of this extension be higher than this afterbody.

Should open portion's end outward is arc portion towards inner bending further.

The beneficial effects of the utility model are: meet EMI shade fixed structure of the present utility model, it includes at least: 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, these anchor clamps are located on each extension, it is provided with the shell fragment that is extended by these extension both sides up, this shell fragment is positioned at the belly of below formation than large space relatively, be extended down to the neck that the top is punctured into small distance, again upwards then for expanding as the outer portion of opening, by this, the side plate that makes the EMI shade can be held fixing in the mode into the position of plugging together, and maybe can upwards extract and reaches the purpose of the operation and the maintenance of simple separation.

Embodiment

The utility model EMI shade fixed structure basic structure as shown in Figures 1 and 2, this fixed structure 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 belly 122 of below formation than large space relatively, is extended down to the neck 123 that the top is punctured into small distance, more upwards then for expanding as the outer portion 124 of opening.

During whole the use, as shown in Figure 3, this fixed structure 1 can be fixed in earlier on the circuit board 2, other has an EMI shade 3 to assemble fixing down by this fixed structure 1 top, by this, please consult Fig. 4 and shown in Figure 5 simultaneously, with two shell fragments, 121 formed bellies 122, has a suitable elastic space, neck 123 then is subjected to the elastic reaction of belly 122 and has the function of the side plate 31 of this EMI shade 3 of clamping, opens portion 124 outward and then has guiding side plate 31 and strut neck 123 according to this to enter belly 122 fixing.

Moreover, 112 of the planar portions 111 of this fixed structure and this extensions further are formed with segment difference section 113, as Fig. 1 and shown in Figure 6, the height that makes this extension 113 is a little more than this planar portions 111, these extension 112 ends also are formed with afterbody 114, and 112 of this afterbody 114 and this extensions also are formed with segment difference section 113, the height that makes this extension 112 is a little more than this afterbody 114, this planar portions 111 then is positioned at same plane with this afterbody 114, when so this fixed structure 1 is welded in

circuit board

2,2 of this extension 112 and this circuit boards form an excessive glue space, but allow 21 overflows of unnecessary scolder to the glue space of should overflowing.

In addition, shown in second embodiment of Fig. 7, outer portion's 124 ends of this fixed structure are arc portion 125 towards inner bending further, can avoid this outer portion 124 to cause the danger of scratch.
