Embodiment
Below will combine accompanying drawing, specific embodiments of the invention and embodiment specify, and described specific embodiment in order to explain the present invention, is not to be used to limit embodiment of the present invention only.
As shown in Figure 1, Fig. 1 is the exploded view of the quick detachable radome of the present invention before assembling, is example with the radome that is used to shield the BB chip on the smart mobile phone mainboard, and said quick detachable radome comprises the capping 120 of the weldering frame 110 and the metal of metal; Said capping 120 is used to be fastened on said weldering frame 110 when assembling; In conjunction with shown in Figure 2; Fig. 2 is the partial structurtes figure of the quick detachable radome of the present invention after assembling; Said capping 120 is wrapped in the outside of said weldering frame 110, the BB chips 100 that are positioned at said weldering frame 110 inside behind the welding assembly are played the effect of shielding and auxiliary heat dissipation; Wherein, For the ease of dismounting and assembling, in conjunction with shown in Figure 3, Fig. 3 is the partial structurtes enlarged drawing of the capping in the quick detachable radome of the present invention; The sidewall 121 of said capping 120 peripheries is provided with the line of rabbet joint 123 that is communicated to base 122; Form the line of rabbet joint 123 of open type, the sidewall 121 of said capping 120 is carried out part cut apart, to reduce the bonding strength of itself and said weldering frame 110; The said line of rabbet joint 123 vertically is provided with, and for example, the said line of rabbet joint 123 is rectangular, and the base 122 of the vertical said capping 120 in long limit of the rectangle line of rabbet joint 123 is provided with.
In the preferred implementation of the quick detachable shielding of the present invention; As shown in Figure 1; The said line of rabbet joint 123 can be arranged along 122 lateral separations, base of said capping 120 sidewalls 121, with said capping 120 of further reduction and the firm degree that said weldering frame 110 is connected, is easier to dismounting.
Be preferably, uniformly-spaced be provided with between a plurality of lines of rabbet joint 123, the distance between promptly adjacent two lines of rabbet joint 123 equates, evenly weakening the rigidity of said capping 120 sidewalls 121, homogenizing reduces itself and the bonding strength of said weldering frame 110, guarantees the fastening quality.
Further, also can be provided with lightening core 115, be used to alleviate the weight of said weldering frame 110 at the end face 114 of said weldering frame 110; And, in said lightening core 115, can be provided with the connecting portion 116 that is connected to each top side wall, be used to increase the bulk strength of said weldering frame 110, the end face 114 that said connecting portion 116 exceeds said weldering frame 110 is provided with.
Accordingly; Be provided with the rib 126 of adaptive said connecting portion 116 at the end face 124 of said capping 120; Be used to strengthen the bulk strength of said capping 120, said rib 126 is the end face 124 of the said capping 120 of protrusion outwards, exceeds the connecting portion 116 of said weldering frame 110 end faces 114 with containing.
Concrete, the connecting portion 116 on the said weldering frame 110 comprises the intercell connector 116a and the 116b of two right-angled intersections; Rib 126 in the said capping 120 comprises square convex edge 126a and the cross convex edge 126b that on this square convex edge 126a, is provided with, and the cross convex edge 126b in the said capping 120 and the intercell connector 116a and the 116b of two right-angled intersections on the said weldering frame 110 are suitable.
Simultaneously; The lightening core 115 of said weldering frame 110 end faces 114 also can play the further effect that improves radome heavy industry performance; This moment, the size of said lightening core 115 need surpass device such as BB chip 100 sizes that shielded, and when needing rework, pulled down said capping 120 thus; Cut off intercell connector 116a and 116b on the said weldering frame 110; Can be under the situation that need not take off said weldering frame 110 heavy industry BB chip 100, behind heavy industry, buckle said capping 120 then again, and then also can the shield effectiveness of radome do not impacted.
In addition, in order to improve welding performance, knot also can be provided with the breach 113 that is communicated to base 112 on the sidewall 111 of said weldering frame 110 peripheries, with the pad increase of cooperation PCB and the contact area of scolding tin, climbs tin when being convenient to weld.
In the preferred implementation that the above capping of the present invention and said weldering frame are fastened and connected; As shown in Figure 1; The lateral separation is arranged with a plurality of outstanding to the inside salient points 127 on the sidewall 121 of said capping 120, sphere shape boss point etc. for example, and also the lateral separation is arranged with a plurality of through holes 117 on the sidewall 111 of said weldering frame 110; Corresponding one by one with said salient point 127, for example put corresponding circular hole etc. with boss; In fastening to said capping 120 on the said weldering frame 110, each salient point 127 that is arranged on said capping 120 sidewalls 121 all is buckled in each through hole 117 on corresponding said weldering frame 110 sidewalls 111 one by one, with the reliability that guarantees to be fastened and connected.
In conjunction with shown in Figure 2, be preferably, in order to reduce technology difficulty; Reduce production cost, the capping 120 of metal and the weldering frame 110 of metal all can be through the mode moulding of bending, therefore; Corner in said capping 120 can be provided with technology groove 128, after bending, produces the phenomenon of interfering each other to avoid intersecting two side 121, and; Corner at said weldering frame 110 also can be provided with technology groove 118; After bending, produce the phenomenon of interfering each other to avoid intersecting two side 111, avoided thus making that through said capping 120 of the mode moulding that stretches and weldering frame 110 line of rabbet joint and the breach on the said weldering frame 110 in the said capping 120 all can be accomplished in the blanking operation in its first time separately; Reduce technology difficulty, practiced thrift production cost.
In conjunction with shown in Figure 3; Be preferably; Salient point 127 on said capping 120 sidewalls 121 and the said line of rabbet joint 123 interlaced arrangements, the inhomogeneities that both can avoid said capping 120 to be connected with said weldering frame 110 can guarantee the consistency of said capping 120 sidewalls 121 local strengths again; Concrete, can whenever 1 said line of rabbet joint 123 be set as required at a distance from 1 ~ 3 said salient point 127.
Compare with radome of the prior art; A kind of quick detachable radome provided by the present invention; Owing to adopted the two-part construction that is fastened and connected, and on the capping sidewall that plays shielding action, adopted the line of rabbet joint design of opening, greatly reduced capping and the bonding strength that welds frame; Be convenient to when heavy industry, dismantle and assemble, very favourable to improving the heavy industry performance of radome after welding.
Should be understood that; The above is merely preferred embodiment of the present invention, is not sufficient to limit technical scheme of the present invention, concerning those of ordinary skills; Within spirit of the present invention and principle; Can increase and decrease according to above-mentioned explanation, replacement, conversion or improvement, and all these increases and decreases, replacement, conversion or improve after technical scheme, all should belong to the protection range of accompanying claims of the present invention.
