Abstract
The utility model discloses a screening shield for IC. The screening shield includes a screening frame and a screening cover. The screening frame includes a frame-shaped substrate, the edges of which protrude upwards to form a first side plate. The screening cover includes a cover plate, the edges of which protrude downwards to form a second side plate. The screening cover is arranged on the screening frame. A first positioning element is arranged on the first side plate, a second positioning element is arranged on the second side plate, and the first positioning element is matched with the second positioning element. By fixing the screening frame and the screening cover with the first and the second positioning elements, the screening cover is prevented from falling from the screening frame during working, thus safety and reliability of the screening cover are improved.
Description
Technical field
The utility model relates to the radome that is used for IC.
Background technology
As shown in Figure 1, in order to shield the radiation of IC on the mobile phone, radome is set, radome is the box body of below hollow out, and IC is loaded on the pcb board, the edge joint weld of radome lower surface 1 ' is connected on the pcb board in the IC outside; During maintenance, earlier radome is taken off with heat gun, repair IC then, after repairing finished, in the radome welding, such time of reprocessing was long again, and efficient is low.
The inventor of this patent proposes a kind of radome of separate type at the problems referred to above, comprises mask frame and screening cover, and described mask frame comprises substrate, and the substrate outer rim upwards protrudes out and forms first side plate; Screening cover comprises cover plate, and the cover plate outer rim protrudes out downwards and forms second side plate, and cover plate places the substrate top, and second side plate is connected with the surface of first side plate.Adopt screening cover directly to cover the fit system that is located on the mask frame, reliability is often not enough.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the above problems, and is provided for the radome of IC.
The utility model realizes that the above-mentioned purpose scheme is: be used for the radome of IC, comprise mask frame and screening cover, described mask frame comprises substrate, and substrate is a frame shape, and the substrate outer rim upwards protrudes out and forms first side plate; Screening cover comprises cover plate, and the cover plate outer rim protrudes out downwards and forms second side plate, and the screening cover lid is located on the mask frame, on described first side plate first keeper is set, and second keeper is set on second side plate, and first keeper and second keeper are complementary.
The inner surface of described second side plate is connected with the outer surface of first side plate, and second keeper is the projection that is distributed in the second side plate inner surface, and first keeper is the hole that is distributed on first side plate.
Adopt the beneficial effect of above scheme:
First keeper that employing is complementary and second keeper fixed mask frame and the screening cover, when avoiding using, screening cover breaks away from from mask frame, has improved the fail safe and the reliability of radome.
Projection and hole all adopt the punch forming mode to obtain, the punch forming of projection is greater than the influence of the punch forming in hole to flatness to the influence of flatness, because mask frame need weld together by tin cream with pcb board, therefore, the requirement of mask frame flatness is higher than the flatness requirement of screening cover, and the flatness of mask frame generally requires below 0.1mm projection to be set on screening cover, the hole is set on the mask frame, can improves the qualification rate of radome.
Description of drawings
Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1 is the structural representation of existing radome.
Fig. 2 is the structural representation of the utility model mask frame.
Fig. 3 is a structural representation of the present utility model.
Embodiment
The radome that is used for IC shown in Fig. 2,3, comprises mask frame 1 and screening cover 2, and described mask frame 1 comprises substrate 11, and substrate 11 is a frame shape, and substrate 11 outer rims upwards protrude out and form first side plate 12; Screening cover 2 comprises cover plate 21, and cover plate 21 outer rims protrude out downwards and form second side plate 22, and screening cover 2 lids are located on the mask frame 1, and cover plate 21 places substrate 11 tops, and second side plate 22 is connected with the surface of first side plate 12.
If IC goes wrong in the radome, needn't look like prior art, whole radome is taken off with heat gun earlier, can directly screening cover be taken off, repair IC then; Repairing finishes, and also need not again the radome manual welding to be gone back, and only screening cover need be covered on mask frame again to get final product, and adopts this kind scheme, has greatly shortened maintenance time, improves maintenance efficiency, thereby reduces maintenance cost.
Jagged on second side plate 22, on first side plate 12 shielding part 121 is set, described shielding part 121 is corresponding with the breach on second side plate 22.Screening cover 2 is to be bent to form after the metallic plate of monoblock is sheared, in the process of making, reason in the bending place of second side plate 22 because of technology can stay breach, in order to improve shield effectiveness, therefore when making first side plate 12, the position of corresponding breach can not form breach, but one-body molded be shielding part 121, the breach that will form because of the reason of technology is arranged on second side plate, 22 places, when such first side plate 12 and second side plate, 22 couplings, just can not stay the shielding breach.
Be provided with on first side plate 12 and on first keeper, 122, the second side plates 22 second keeper, 222, the first keepers 122 be set and second keeper 222 is complementary, be used for fixing mask frame 1 and screening cover 2.
The inner surface of second side plate 22 is connected with first keeper 122 by second keeper 222 with the outer surface of first side plate 12, second keeper 222 is for being distributed in the hole on second side plate 22, and first keeper 122 is for being distributed in the projection of first side plate, 12 outer surfaces.
Second keeper 222 can also be for being distributed in the projection of second side plate, 22 inner surfaces, and first keeper 122 is corresponding for being distributed in the hole on first side plate 12.Projection and hole all adopt the punch forming mode to obtain, the punch forming of projection is greater than the influence of the punch forming in hole to flatness to the influence of flatness, because mask frame 1 need weld together by tin cream with pcb board, therefore, the requirement of mask frame 1 flatness is higher than the flatness requirement of screening cover 2, and the flatness of mask frame 1 generally requires on screening cover 2 projection to be set below 0.1mm, on the mask frame 1 hole is set, can improves the qualification rate of radome.
Suction cup carrier 111 also is set, two opposite side of suction cup carrier 111 bridge joint substrates 11.Because mask frame 1 adopts metallic plate to shear and is bent to form, and for ease of making, suction cup carrier 111 is set, suction cup carrier 111 is one-body molded with substrate 11, can strengthen the intensity of substrate 11, thereby is stablized, mask frame accurately, improves the reliability of radome.
The width at described suction cup carrier 111 two ends is less than the width in the middle of it, when the IC in the radome keeps in repair, sometimes need whole taking-up back place under repair with IC, so just require suction cup carrier 111 is cut off, the width at suction cup carrier 111 two ends is less than the structure of the width in the middle of it, can conveniently cut off suction cup carrier 111, further improve the efficient of maintenance IC.
