Description
Technical field
The present invention relates to a kind of radome upper and lower cover fastening structure.
Background technology
The radome of the electronic component that uses at present generally is to comprise inside casing and loam cake; Inside casing is connected with the substrate that electronic component is set; Electronic component is enclosed among inside casing; Then loam cake is fastened on outside the inside casing, covers in loam cake inside with making electronic component sealing, with reach prevent between the electronic component or with the electromagnetic interference of outside.Radome upper and lower cover fastening structure especially inside casing needs to be connected with substrate; Flatness to connecting the bottom surface is had relatively high expectations; Therefore flatness directly influences shield effectiveness, and to be that flatness is defective cause most of defective products, in order to reach the flatness requirement; Make processing technology very complicated, increased production cost simultaneously.On the other hand, inside casing is not had a versatility, can only be used with a kind of loam cake of specification.And the coordinate force of loam cake and inside casing is difficult to grasp, if coordinate force is excessive, then needs repairing or when changing, loam cake is difficult for prying open, or in the process of sled, deforms, and can not continue use when electronic component breaks down; If coordinate force is too small, then loam cake is prone to come off from inside casing.
Summary of the invention
Technical problem to be solved by this invention is to overcome defective of the prior art, and a kind of radome upper and lower cover fastening structure is provided, and does not need complicated processing technology, has improved yields, has more versatility, has grip better simultaneously.
For solving the problems of the technologies described above, the present invention provides a kind of radome upper and lower cover fastening structure, it is characterized in that, comprises
Loam cake,
The a plurality of bases that are held on the loam cake sidewall and are connected with substrate;
Said base have a formation plane the bottom surface, be formed at the adsorption section that at least one clamping part and that is used for the clamping loam cake on the bottom surface is suitable for suction nozzle absorption;
Said loam cake sidewall is provided with stop part towards the one side at least of said clamping part.
Said clamping part comprises two holding pieces that are oppositely arranged and form a grasping part, and a side of two holding pieces is connected with the bottom surface respectively or is made of one piece, and opposite side forms and can hold the opening that loam cake inserts.
At least one said holding piece is an arc-like sheet, and this arc-like sheet has a convex surface towards another holding piece, and the grasping part that two holding pieces are formed has a bottleneck, and the loam cake sidewall that inserts grasping part is formed a chucking power.
Said loam cake sidewall is provided with stop part towards the one side of said arc-like sheet, and after said loam cake inserted grasping part, said stop part was arranged in the inner grasping part of bottleneck that said convex surface forms.
Said stop part is one or more raised points, or is a continuous or interrupted raised item.
Minimum range between said two holding pieces is less than the thickness of said loam cake sidewall.
On one of them said holding piece a through hole is set at least, said loam cake sidewall is provided with stop part, and when said loam cake inserted between said two holding pieces, the stop part that covers on said was stuck in the through hole of said holding piece.
Said stop part is convexity or the pawl that protrudes from said loam cake sidewall surfaces.
On the said loam cake sidewall relative with clamping part and with stop part is set a different side side is provided with compensation section, said compensation section is one or more salient points, or be one section continuously or the interrupted raised item of multistage.
The beneficial effect that the present invention reached:
Radome upper and lower cover fastening structure of the present invention adopts the radome base of a plurality of monomer-types, only needs to guarantee the bottom surface flatness of each base, and processing technology is simple, has reduced the defective products rate that causes because of flatness is defective; And be prone to match with the loam cake of plurality of specifications, versatility is good, according to the specification of loam cake base is arranged on four clip positions of sidewall of loam cake, with getting final product in four bases of loam cake insertion.The loam cake sidewall is provided with and prevents its stop part that skids off from base, compensation section, has improved grip.

Embodiment
Below in conjunction with accompanying drawing the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
Like Fig. 1, Fig. 2, shown in Figure 3; Radome upper and lower cover fastening structure of the present invention comprises a plurality of monomer-type bases 2 and loam cake 1; It is that base 2 is set to four that the base 2 that promptly cooperates with loam cake 1 is set to a plurality of, preferable modes, matches with the size of loam cake 1 in the position; But be arranged on the position of loam cake 1 both sides clamping loam cake sidewall, to the stable chucking power of loam cake 1 effect one.Base 2 by a traditional underframe, have bigger contact area when being connected and be improved to a plurality of monomer-type bases of employing of the present invention with substrate; Form a plurality of small footprint 2 with bottom surface 21 of small size, when being connected with substrate, contact-making surface reduces relatively; Base adds man-hour; Its bottom surface flatness is prone to guarantee that processing technology is simpler, has improved accepted product percentage.
Like Fig. 4, shown in Figure 5, in other embodiments, comprise two relative holding pieces 25 in the clamping part of base, one of them holding piece is an arc-like sheet 250, another holding piece is a vertical plate 254.
On the basis of embodiment 1; Further; A holding piece is provided with through hole 2501 therein, and the loam cake sidewall is provided with the stop part 12 that cooperates with through hole towards the face of this holding piece, the loam cake sidewall with the different another side of stop part be set be provided with compensation section 13.
One through hole 2501 is set on arc-like sheet 250 in the present embodiment; Loam cake sidewall 11 is provided with stop part 12 towards the one side of arc-like sheet 250; When loam cake 1 inserts between 25 of two clampings; Stop part 12 on the loam cake 1 is stuck in the through hole 2501 of arc-like sheet 250 just, prevents that loam cake 1 from skidding off disengaging from base 2.
Preferable mode is that stop part 12 is raised points or pawl 121, makes loam cake 1 can insert base 2 smooth-goingly, and after loam cake 1 inserted base 2, pawl 121 snapped in the through hole, is difficult for slippage from through hole 2501.
Further; When preventing that upper cover thickness is thin, the situation that chucking power is not enough, loam cake sidewall 11 and clamping part 22 relative, with stop part 12 different side sides be set be provided with compensation section 13; Compensation section 13 can be one or more salient points 131; Also can to increase the sectional thickness of loam cake, improve chucking power for one section continuous or interrupted raised item of multistage at the compensation section place.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and distortion, these improvement and distortion also should be regarded as protection scope of the present invention.
