Description
Technical field
The utility model relates to a kind of six barrier enclosure boxes, is specifically related to that a kind of performance is good, six barrier enclosure boxes of cost of raw material lowland environment-friendly type.
Background technology
Along with the progress and the development of science and technology, electronic equipment has become an inseparable part in people's life.For improving the performance of electronic equipment, its frequency of operation constantly refreshes in producer.Yet the operate as normal with its other compatible electronic equipments in the electromagnetic radiation pollution serious threat that high-frequency circuit produced, and also there is considerable influence aspects such as communication quality, health.So the electron radiation that reduces electronic product is very necessary.Usually through circuit board being placed can or metal framework, adopt electroplating technology again in the industry, utilize metal material that interference source is closed with function of shielding at an above-mentioned can or a metal frame surface plating skim.There is following shortcoming in this method: material cost is high, adopts the electroplating technology environmental pollution damage big, and difficulty of processing is big.
Existing six shielding products generally all are to adopt the housing and a flap of an opening of being processed by shielding material to be welded together to form a closed cassette construction packages.Adopt this packaged type, not only technology difficulty is big, and product inside is prone to tin sweat(ing), possibly cause very big influence to performance of products.In addition, heavy metals such as the nickel of the electroplating process for surface of metal shell use, cadmium also can cause serious pollution to environment.
Be 200920051805.3 at application number and be called in the Chinese utility model patent of ' six barrier enclosure boxes of a kind of nested type '; Mention a kind of boss that stretches out in the setting of barrier enclosure box bottom; Relevant position at screening can is provided with the through hole that holds corresponding boss; Let bottom and its screening can tabling of barrier enclosure box through this structure, saved the welding step in the traditional handicraft, constantly realized six shieldings and solved the residual problem of tin sweat(ing).
But; Six barrier enclosure boxes of the nested type of said structure; In giving enclosure, pour into liquid such as liquid-state silicon gel, resin etc. with fix electronic devices and components in the enclosure, when strengthening the insulativity between the components and parts; Lead to the hole site is prone to the excessive of liquid, causes silica gel, resin etc. to fill with, and influences properties of product.In addition, the whole metal material that adopts of the enclosure in the above-mentioned patent is processed, and the cost of raw material is higher.
The utility model content
The utility model technical problem to be solved is: provide that a kind of performance is good, six barrier enclosure boxes of cost of raw material lowland environment-friendly type.
The utility model technical problem to be solved realizes through following technical scheme: six barrier enclosure boxes that a kind of performance is good; Comprise screening can, be provided with the base that buckles into the inboard side of screening can; It is characterized in that: an opposite flank of said base is provided with through hole; Said screening can is provided with the boss with said through hole coupling, and described screening can realizes that with the cooperation of boss buckle-type is connected through above-mentioned through hole with base.
The utility model has been changed the position of being provided with of boss and through hole in the prior art; Be about in the prior art boss to be set in that through hole is set on the screening can on base; Change in that boss is set on the screening can through hole with its coupling is set on base; So the side of screening can is an enclosed construction, and the boss on the screening can be blocked the through hole on the base, and liquid was excessive when the enclosed construction of its side can further stop filling liquid; Eliminated because of liquids such as silica gel and can't fill the influence that causes, enhanced product performance the aspects such as fixing, insulativity of components and parts in the enclosure.
The utility model can be on the such scheme basis further improves, and provide six low barrier enclosure boxes of a kind of cost of raw material: described base is the plastic cement base, the base inboard be provided with one with the suitable shielding lamellar body of medial surface of said base; Described shielding lamellar body is the lamellar body that pcb board or copper sheet or aluminium flake or other materials with shielding action are processed.At the inboard lamellar body that is provided with of plastic cement base with shielding action, do not influence six function of shielding on the one hand, another is convenient with the metab before the replacement of plastic cement base, has saved raw-material cost greatly.
The boss that each side of the described enclosure of the utility model is complementary and the quantity of through hole are no less than two pairs; The height of described boss is identical with the degree of depth of said through hole.
Described screening can inboard is provided with the splicing ear of the redundant electric charge on being used to derive the shielding lamellar body and be connected the electronic devices and components that shield lamellar body, and said splicing ear connects said shielding lamellar body.
The utility model can improve as follows on the such scheme basis, and further provide a kind of environment-friendly type six barrier enclosure boxes: described screening can is the housing that hard aluminium alloy is processed, and housing has the top layer through anodic oxidation and blasting treatment.
The utility model screening can is processed by hard aluminium alloy; And the surface is through anodic oxidation and blasting treatment; Compare copper alloy electroplating technology of the prior art, more environmental protection, the nickel of having avoided discharging in the electroplating process, hexavalent chromium compound are to the pollution of human body, environment.
Relative prior art the utlity model has following beneficial effect:
1) the utility model is through the position that is provided with of boss and through hole in the transposing prior art, and structure is when pouring into liquid such as silica gel before having solved, and liquid is prone to overflow the through hole on being located at screening can and causes silica gel to fill influencing problems such as the fixing of components and parts in the enclosure, insulation; Improved performance of products; In addition, the screening can of the utility model adopts buckle-type to be connected with base, is easy to assembling; Compared to prior welding mode, encapsulation flow process and technology have been simplified; The design of boss and through hole has avoided base and screening can because of the situation that interlock does not tightly come off, and has reinforced the packaging effect of six shieldings;
2) at the inboard lamellar body that is provided with of plastic cement base, six shieldings have been realized equally with shielding action; The plastic cement base is set replaces metab before, saved raw-material cost, thereby saved production cost;
3) screening can is selected the housing of hard aluminium alloy, and surface of shell is through anodic oxidation and blasting treatment, and with respect to electroplating technology of the prior art, the technology of the utility model is simpler; The surface property of painted, heat radiation and housing all is improved, and the more important thing is, has avoided the heavy metal pollution in the electroplating process; Can be through the RoHS checking, very environmental protection, in addition; The surface treatment mode that the utility model is taked is electroplated, and has also reduced cost.
