A kind of combined type shielding part structure (shielding external member), including mainboard are present embodiments provided, is arranged on mainboard
Pad, pass through the shielded rack on mainboard of pad solder, and the radome being fastened on shielded rack.Optionally, the screen
Cover and assembled when cover fastens with shielded rack by the convex closure on radome bending edges and shielding top of support one open section.The shielding external member
In all consumption electronic products that may be applicable to shielding part device.
Fig. 4 is pad distribution schematic diagram on the mainboard of the embodiment of the present invention, and Fig. 5 is the shielded rack plane of the embodiment of the present invention
Figure, Fig. 6 are the shield plane figures of the embodiment of the present invention, and Fig. 7 is the frame cover assembling lateral side view of the embodiment of the present invention, as Fig. 4,
5th, shown in 6, a kind of combined type shielding part structure.There are several places on the long cross direction of pad profile on the mainboard of wherein Fig. 4 signals
2.1 in the place such as Fig. 4 that pad spacing is 4.0MM；Respectively there is at one breach on the long cross direction bending edges of shielded rack described in Fig. 5 such as
3.1 in Fig. 5；The long cross direction of radome described in Fig. 6, which corresponds to shielded rack indentation, there, has at one convex closure coordinate, and radome is accordingly herein
4.1 in perforate such as Fig. 6.
Fig. 8 is sectional view after the assembling of frame of embodiment of the present invention cover, and Fig. 9 is partial enlargement at B shown in Fig. 8 of the embodiment of the present invention
Figure, cover (radome) are coordinated by breach on convex closure and shelf (shielded rack) bending edges, and this cooperation position is located exactly at pad
The bigger place of upper spacing, can not so consider that pad climbs tin problem herein, i.e., cover herein bending edges can do and shelf
Concordantly, other positions cover bending edges height is vacated compared with shelf climbs tin height.
Further illustrate, as schematically shown in Figure 9, radome 0.15MM material, shielded rack are used in the present embodiment
0.2MM material, radome convex closure diameter 0.5MM, assembled with shielded rack, rigging position is because pad has empty avoiding, without considering
Tin height is climbed, the shielding cover height of bending herein is concordant with shelf after can assembling, and other positions bending is highly preferably
0.75MM (size as shown in Figure 7, this is reduced to 0.55MM apart from minimum)；Shielded rack height is radome bending height
0.75 is added with climbing tin height 0.25MM (ensureing that radome can assemble after shielded rack paster), therefore the present embodiment shielding part is whole
Body is highly 0.75+0.25=1.0MM.
The scheme of the present embodiment is avoided on shielded rack because of mating holes compared with correlation technique as shown in Figure 1, Figure 2, Figure 3 shows
Assemble and influence the whole height of shielding part, also take full advantage of pad distribution, allow radome to coordinate convex closure shaping without influenceing
To shielding part height, and breach is easy to disassemble on shielded rack bending edges, is not influenceed by scolding tin height also, related that can reach
Greatly save motherboard space while technology requires, and it is simple in construction, be easily achieved.
Anticipate as shown in this embodiment, by conventional shielded rack material thickness 0.2MM, radome material thickness 0.15MM
To calculate, correlation technique shielding part whole height accomplishes that 1.35MM is more reasonable, as shown in Figure 3, coordinates on shelf bending edges
Pitch-row bending edges root need to ensure to be not less than 0.15MM, otherwise may influence the assembling effect of shielded rack and radome, cover
Need to reserve after assembling and climb tin height not less than 0.25MM, mating holes presses 0.6MM on shelf, therefore shielding part total height is
0.25+0.6+0.15+0.2+0.15=1.35MM.And 1.0MM, such as Fig. 9 can be accomplished with the general shielding part integral thickness of this structure
It is shown, it is even lower.
As another optional embodiment of embodiment, coordinate shape using shielded rack breach stretching wall and radome salient point
Formula, the salient point on radome can also be cancelled, shielded rack stretching wall is lengthened and directly coordinated with the breach on radome, Tu10Shi
Pad distribution schematic diagram on the present embodiment mainboard, Figure 11 are the present embodiment shielded rack plans, and Figure 12 is the present embodiment radome
Plan, such as Figure 10, shown in 11,12.Wherein, Figure 10 is pad profile on mainboard, has a few place's pad gap ratios on long cross direction
Position 1 in larger place such as figure；Figure, respectively have on the 11 long cross direction bending edges of shielded rack at one in breach stretching wall such as figure
Position 2；The long cross direction of radome described in Figure 12, which corresponds to shielded rack breach and had on bending edges and top surface, accordingly opens one of breach such as
Position 3 in figure, due to this position gap of radome, to ensure intensity herein, bending edges height and other positions herein
Height, ensureing that radome is concordant with shielded rack bending edges after being assembled with shielded rack, Figure 13 is the present embodiment shield plane figure,
Position 4 in Figure 13.To sum up radome with shielded rack is coordinated by the position 2 of shielded rack and the position 3 of radome, radome
The part of position 4 just at the position 1 of pad, can not so consider to climb tin influence.Separately due to radome after this Standard
Dismounting can be a little difficult, therefore the dismounting mouth of radome, so convenience blade or pincet are reserved at Figure 13 middle position 5
Auxiliary dismounting.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
