Description

Computer rear window shell fragment

The utility model is about a kind of computer rear window shell fragment, the computer rear window shell fragment that the good anti-electromagnetic radiation of particularly a kind of simple in structure, convenient disassembly and tool disturbs.

Along with the frequency of the inner set wafer of computer (quickening wafer as central processing unit and figure) is more and more fast to strengthen the ability of its deal with data, the lifting of various wafer frequencies makes the also corresponding increase of the intensity of its radiation that generates electromagnetic waves, and the computer casing computer rear window important area that to be electromagnetic wave leak, and on the existing computer rear window usually installing computer rear window matte or ground lug etc. to prevent electromagnetic interference.

As No. the 84202220th, Taiwan patented claim, its be each grid sheet of computer rear window up and down the edge inner face punching press of both sides be formed with some recessed, it is prominent that the corresponding punching press in each groove lid both sides is formed with some lids, thus the groove cover lock admittedly the prominent sheet that can place of its lid of back realize that electromagnetic wave can't pass through in recessed.Yet, grid sheet and groove cover formed recessed and lid is prominent, can cause loose contact and cause and can not effectively prevent electromagnetic interference.

The relative patent the 5th of No. the 84216497th, the Taiwan patented claim and the U.S. and for example, 650, No. 922, it all is the improvement of another kind of computer rear window, it comprises a plug-in card positioning seat, one ground connection guide plate and some expansion plug-in cards, the ground connection guide plate is mainly the rectangular bending-like of a vertical surface and its top, vertical surface is provided with the identical fluting of the fluting on some corresponding plug-in card positioning seats, and respectively be provided with a corresponding pintle hook body on the vertical surface of each fluting left and right sides, and each fluting bottom is the grab that is downward, and the both sides of the edge of each fluting are provided with the several pieces of contact chips that outwards protrude in addition.Be inserted in the plug-in card positioning seat by the ground connection guide plate, the contact chip that makes the ground connection guide plate closely contacts with plug-in card and realizes good ground connection effect.Yet the integrally formed ground connection guide plate part of this kind is damaged just all subscription rates, cause great waste, therefore relatively and the expansion board number that every kind of computer installed is not quite similar, and computer casing computer rear window fluting number also is not quite similar, and makes this ground connection fairlead not have a versatility.

Other relevant therewith patent sees also Taiwan patented claim the 84209619th and No. 85107563 etc.

The purpose of this utility model provides a kind of simple in structure, easy to assembly and can effectively prevent the computer rear window shell fragment of electromagnetic interference.

It is good that another purpose of the present utility model provides a kind of versatility, saves the computer rear window shell fragment of material.

The purpose of this utility model realizes by following proposal: a kind of computer rear window shell fragment is to be fixed in the computer rear window.Outwards convex with some conflict sheets along computer rear window shell fragment two lengthwise lateral margins, this conflict sheet comprises an a junction and a contact part, and the two ends of the computer rear window shell fragment sheet of conflicting relatively oppositely is convexly equipped with two and fixes sheets, the bearing of trend of this two fixings sheet is opposite, and all comprise connecting portion, holding division and introduction part, then be provided with on each grid sheet of computer rear window in order to fix the fixing mouth of sheet.This computer rear window shell fragment can fix the fixing mouth that sheet is fastened in window bar sheet behind the computer by it and be fixed in the computer rear window, thereby window is inconsistent can be reduced the slit of computer rear window matte and grid sheet and constitute grounded circuit and buckle by computer rear window shell fragment and computer, thereby effectively prevents electromagnetic interference.

Pass through technique scheme, computer rear window shell fragment of the present utility model not only can simply promptly be installed on the grid sheet of computer rear window, and can reduce the slit between computer rear window matte and grid sheet and constitute grounded circuit, thereby can effectively prevent electromagnetic interference.

With reference to the accompanying drawings, in conjunction with the embodiments the utility model is further described

Fig. 1 is the three-dimensional exploded view of the utility model computer rear window shell fragment and computer rear window, computer rear window matte.

Fig. 2 is the stereographic map of the utility model computer rear window shell fragment.

Fig. 3 is another stereographic map of the utility model computer rear window shell fragment.

Fig. 4 is the three-dimensional combination figure of the utility model computer rear window shrapnel device in computer rear window and computer rear window and matte conflict.

As shown in Figure 1, computer rear window shell fragment 10 of the present utility model can be installed on computer rear window 40, and can and computer rear window matte 50 inconsistent with the ground connection that constitutes 50 of computer rear window 40 and mattes and prevent electromagnetic interference.

See also Fig. 2 and Fig. 3, computer rear window shell fragment 10 outwards convexes with some conflict sheets 16 along its two lengthwises lateral margin, and the two ends of computer rear window shell fragment 10 sheet 16 of conflicting relatively then oppositely is convexly equipped with two and fixes sheets 18,21.Conflict sheet 16 comprise the segment distance that stretches out connecting portion 162 and by connecting portion 162 continue to extend and with the contact part 164 of lengthwise lateral margin almost parallel.The bearing of trend of two

fixing sheets

18,21 is opposite, it comprises the connecting portion 182,212 that tilts to extend respectively, and continue to extend and the holding divisions 184,214 slightly parallel, and respectively by the introduction part 186,216 of holding division 184,214 more outward-dipping extensions with the lengthwise lateral margin from connecting portion 182,212.

See also Fig. 1 again, computer rear window 40 is provided with some openings 42 and reaches the some grid sheets 44 that distribute alternately with opening 42,

relative fixing mouth

46,48 all is set, with the fixing sheet 18,21 (showing as Fig. 3) that fixes computer rear window shell fragment 10 respectively on the grid sheet 44.And computer rear window matte 50 can be fixed in computer rear window 40 and be pressed on computer rear window shell fragment 10 at opening 42 places.

Show for another Fig. 1 and Fig. 4, during assembling, only the application of force is pulled the two ends of rolling over computer rear window shell fragment 10 and is made its generation elastic deformation slightly, be placed on grid sheet 44 places of computer rear window 40 then, the

fixing mouth

46,48 that makes the

fixing sheet

18,21 of computer rear window shell fragment 10 align grid sheet 44 unclamps then, the

fixing sheet

18,21 of computer rear window shell fragment 10 just can import by its introduction part 186,216, fixes (Fig. 3 shows) and make the holding division 184,214 that fixes

sheet

18,21 and fix mouth 46,48.Then, computer rear window matte 50 can be fixed in opening 42 places of computer rear window 40, and inconsistent with the conflict sheet 16 of computer rear window shell fragment 10 1 sides on the opening 42 both sides grid sheets 44, thus effectively prevent electromagnetic interference.In addition, the width difference of the

fixing sheet

18,21 of computer rear window shell fragment 10, and the also corresponding difference of width of the

fixing mouth

46,48 of computer rear window 40 is to prevent to adorn when computer rear window shell fragment 10 is assembled in computer rear window 40 anti-phenomenon.
